The majority of the body’s organs are impacted by ambient air pollution (AAP), which is currently a serious environmental global health issue. The objective of this work was to assess the impact of ozone (O3 ), sulfur dioxide (SO2 ), and AAP on oxidative stress (OS) and lipid profile indicators in male Wistar rats. To this end, these rats were exposed for three hours each day for five weeks in control, AAP, O3 (0.6 ppm), and SO2 (10 ppm) groups (each containing 8 animals). Several parameters, such as total antioxidant capacity (TAC), superoxide dismutase (SOD), glutathione peroxidase (GPx) activities, low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triglyceride, and malondialdehyde (MDA), were measured on blood samples. AAP exposure on TAC (P=0.014) and SOD (P=0.05), MDA (P=0.018), and HDL (P=0.003), O3 exposure on TAC (P<0.001), and SO2 exposure on blood serum TAC (P=0.006) all had statistically significant effects. Based on the results, exposure to SO2 and AAP did not significantly alter the lipid profile (P>0.05). According to our research, exposure to O3 , SO2 , and AAP can increase overall antioxidant capacity by stimulating blood serum oxidative defense enzymes. Except for the enhanced effect of O3 exposure on serum HDL, AAP, SO2 , and O3 exposures had no discernible effects on the lipid profile.

With urbanization and industrialization, air pollution is one of the known health hazards and a severe problem in human societies. This study assessed the relationship of SO2, O3, and ambient air pollution on hematologic factors, serum iron, and TIBC in a rat model. A total of 32 male Wistar rats were enrolled in the study. They were randomly divided into the four study groups (n = 8 in each) as follows: The control, SO2 group exposed to 10 ppm, ozone group (O3) exposed to 0.6 ± 0.1 ppm, and ambient air pollution (AAP) group for five weeks (3 h/day). One-way analysis of variance was used to With urbanization and industrialization, air pollution is one of the known health hazards and a severe problem in human societies. This study assessed the relationship of SO2, O3, and ambient air pollution on hematologic factors, serum iron, and TIBC in a rat model. A total of 32 male Wistar rats were enrolled in the study. They were randomly divided into the four study groups (n = 8 in each) as follows: The control, SO2 group exposed to 10 ppm, ozone group (O3) exposed to 0.6 ± 0.1 ppm, and ambient air pollution (AAP) group for five weeks (3 h day-1). One-way ANOVA (analysis of variance) was used to compare parameters. Significant changes in RBC (P=0.026), hemoglobin concentration (P=0.029), mean corpuscular volume (MCV) (P=0.011), mean corpuscular hemoglobin concentration (MCHC) (P<0.001), monocytes (P=0.002), and basophils (P=0.022) were observed between control and AAP groups. The other parameters showed an insignificant difference for these two groups' comparison. In the of leucocytes’ differential counts, only basophils and monocytes were statistically high in the AAP group compared to the control group (P=0.002 and P=0.022, respectively). In terms of serum iron, the differences between the control and SO2 groups (P =0.008), or between the groups of O3 and APP (p=0.028) were statistically significant. The observed hematological and biochemical changes indicated the toxic effects of ambient air particles. Further epidemiological studies are necessary to investigate the impact of other air pollutants like NO2, NO, and CO on hematological and biochemical parameters.

Type 1 diabetes mellitus (T1DM) occurs due to the decrease in insulin secretion following the destruction of pancreatic beta cells. This disease is increasing worldwide, especially among children under the age of 5 years, which is usually associated with irreversible complications such as hepatopathy and nephropathy. The present study aimed to investigate the antidiabetic effect of the heat-killed Actinomycetales species, including Gordonia bronchialis (Gb), and Tsukamurella inchonensis (Ti) in streptozotocin-diabetic rats by oral administration. This experiment was performed in six groups, including healthy control, diabetic control, low-dose Gb (G1), high-dose Gb (G2), low-dose-Ti (T1), and high-dose Ti (T2). Subsequently; the levels of ALT, AST, total protein, albumin, BUN, creatinine, CRP, IL-1β, and IL-2 were measured in the serum samples in the 14th and 21st days. Besides, histopathological lesions were studied in the liver and kidney. Our findings showed that Gb and Ti could alter the examined serum parameters, particularly in the T2 groups. Also, histological examination revealed a remarkable attenuation in the pathological lesions such as focal necrosis, vascular congestion, and hemorrhage in the liver and kidney of the treated rats by Gb and Ti. Here, it is concluded that oral administration of the heat-killed Actinomycetales species, particularly with a high dose of Ti, could beneficially improve the progression of T1DM and its various complications, which can be used to treat T1DM in the future.

In the last decades, numerous studies have focused on the search for new agents to suppress the growth of cancer cells. In this study, we investigated the effect of two novel synthetic coumarin derivatives, namely 2-amino-4-(4-(2-hydroxyethoxy)-3-methoxyphenyl)-5-oxo-4H,5H-pyrano[3,2-c]coumarin-3-carbonitrile and 2-amino-4-(4-hydroxyphenyl)-5-oxo-4H,5H-pyrano[3,2-c]coumarin-3-carbonitrile, on the induction of apoptosis in breast cancer in a mouse model. Breast cancer was induced in BALB/c mice, which were randomly divided into six groups and then underwent the experiment. The groups and treatments included A1: coumarin A with a low dose (10 µm), A2: coumarin A with a high dose (1 mM), B1: coumarin B with a low dose (10 µm), B2: coumarin B with a high dose (1 mM), D: doxorubicin, and C: cancer control/ treatment with normal saline. The samples underwent treatments for 5 weeks. Animals were euthanized, and tissue samples, including the lung, liver, and tumor mass, were collected for histopathological examination. In addition, quantitative real-time polymerase chain reaction (qRT-PCR) was performed to determine some apoptotic markers, such as BCL-2, caspase-9, COX-2, and c-Myc. The qRT-PCR presented that both coumarin compounds could significantly alter the expression levels of BCL-2, caspase-9, COX-2, and c-Myc. Consistent with these results, histopathological observations showed a significant reduction in pathological lesions and severity of malignancy of the tumor mass, as well as a decrease in microscopic metastases in the lung and liver. This suggests that the present new coumarin compounds may induce apoptosis in breast cancer cells by altering some apoptosis-related genes that may play a chemotherapeutic role in breast cancer therapy in the future.

Echinacea purpurea (L.) Moench is a member of the Asteraceae family and is traditionally used mainly due to its immunostimulatory properties. Various compounds including alkylamides and chicoric acid were reported as active ingredients of E. purpurea. Here, we aimed to prepare electrosprayed nanoparticles (NPs) containing hydroalcoholic extract of E. purpurea using Eudragit RS100 (EP-Eudragit RS100 NPs) to improve the immunomodulatory effects of the extract.

The EP-Eudragit RS100 NPs with the different extract:polymer ratios and solution concentrations were prepared using the electrospray technique. The size and morphology of the NPs were evaluated using dynamic light scattering (DLS) and field emission-scanning electron microscopy (FE-SEM). To evaluate the immune responses, male Wistar rats were administrated with the prepared EP-Eudragit RS100 NPs and plain extract in the final dose of 30 or 100 mg/kg. The blood samples of the animals were collected and the inflammatory factors and complete blood count (CBC) were investigated.

In vivo studies indicated that the plain extract and EP-Eudragit RS100 NPs (100 mg/kg) significantly increased the serum level of tumor necrosis factor-α (TNF-α) and interleukin 1-β (IL1-β) whereas the EP-Eudragit RS100 NPs (30 mg/kg) significantly increased the number of white blood cells (WBCs) compared to the control group. Lymphocytes’ count in all groups was increased significantly compared to the control group (P < 0.05) whereas other CBC parameters remained unchanged.

The prepared EP-Eudragit RS100 NPs by electrospray technique caused significant reinforcement in the immunostimulatory effects of the extract of E. purpurea.

Cell-based therapies with certain cell types are touted as novel and hopeful therapeutic intervention in the clinical setting. Here, we aimed to assess the regenerative potential of c-Kit+ cells in the rejuvenation of ovarian tissue and fertility rate in rat model of premature ovarian failure (POF).

Rats were treated with 160 mg/kg/BW of 4-vinylcyclohexene dioxide for 15 days. Freshly enriched rat bone marrow-derived c-Kit+ (MACS) and c-Kit- cells (4×105 cells/10 µL) were transplanted into the ovaries of treatment and control animals. Prior to transplantation as well as 2, 4, 6, and 8 weeks post-transplantation, randomly-selected rats were euthanized and ovarian tissues were subjected to pathophysiological examinations and real-time PCR analyses.

POF status was confirmed by the presence of pathological features and a decreased number of immature and mature follicles compared with the control group (P < 0.05). Histological examination revealed a substantial reduction of atretic follicles in POF rats receiving c-Kit+ cells in comparison with POF rats that did not receive these cells (P < 0.05). Compared with the control samples, angiogenesis-related genes, Angpt2 and KDR, showed increased and decreased expressions in POF ovaries, respectively (P < 0.05). c-Kit+ cells had potential to restore angiogenesis in the ovarian tissue within normal ranges. Systemic levels of FSH did not significantly change in pre- or post-transplantation time points for any group (P > 0.05). Notable reduction of collagen deposition was found in c-Kit-treated rats. Transplantation of c-Kit+ cells also restored the reduced fertility rate (P < 0.05).

The administration of c-Kit+ cells can modulate angiogenesis and pathological changes, leading to the rejuvenation of ovarian function of a rat model of premature menopause.

Type 1 diabetes mellitus (T1DM) has dramatically increased in recent years, especially in young people, and limits the life quality of the patients involved. Thus, many researchers are performing extensive studies to find alternative treatments for DM.

Here, we evaluated the improvement effects of the heat-killed Actinomycetales species, including Gordonia bronchialis, and Tsukamurella inchonensis in streptozotocin-diabetic rats by biochemical, immunological, and histopathological examinations.

The present findings exhibited a dramatic and progressive alteration in the serum levels of IL-6, IL-10 and TNF-α in the diabetic group, which were related to the blood glucose and insulin levels, oxidative stress defense (evaluated by TAC and MDA activities), and the pancreas biochemical indicators (such as amylase and lipase). More importantly, the present results were consistent with the histopathological findings, which included cellular degeneration, vascular congestion, hemorrhage, focal necrosis associated with mononuclear cell infiltration. Interestingly, all of the diabetic changes in the blood serum and tissues improved remarkably in the treated groups by Actinomycetales species.

Surprisingly, most of the current diabetic complications effectively attenuated after oral administration of both Actinomycetales species, particularly with a high dose of T. inchonensis. Thus, it is concluded that the heat-killed Actinomycetales species can prevent and improve the progression of T1DM and its various complications profoundly.

This study investigated the effect of non-surgical periodontal treatment on clinical indices and salivary levels of visfatin, chemerin, and progranulin in diabetic patients with periodontitis.

This interventional clinical trial was performed on 20 patients with type II diabetes mellitus (T2DM) with moderate to severe chronic periodontitis (periodontitis stages II or III according to the new classification of periodontal diseases). Clinical indices, including gingival index (GI), probing pocket depth (PPD), clinical attachment level (CAL) and plaque index (PI), were recorded and visfatin, chemerin, and progranulin adipokines levels were also measured in unstimulated saliva by ELISA technique at baseline and twelve weeks after non-surgical periodontal treatment.

GI dropped from 1.92±0.27 to 0.71±0.14 after the intervention (P<0.001). Also, there were significant changes in the PPD and PI (P<0.001). However, no significant changes were observed in the CAL (P<0.05). The concentrations of all three salivary adipokines decreased after treatment, but this change was statistically significant only for progranulin (P<0.05).

Non-surgical periodontal therapy resulted in improvements in the clinical indices of GI, PPD, and PI in T2DM patients with periodontitis. Moreover, the significant reduction in the salivary level of progranulin after treatment suggests that it might be considered a target inflammatory marker in periodontal diseases.

 Fibroblast growth factor 23 (FGF-23) and its cofactor alfa klotho, are one of the most important factors, directly and indirectly, involved in the process of calcification and atherosclerosis. This study aimed to evaluate the efficacy of a combination of regular exercise during dialysis on quality of life and markers including FGF-23, alfa klotho, and fetuin-A levels.

Forty-five hemodialysis patients aged 61 ± 9.02 years and weight 69 ± 11.25 kg were randomly divided into two training, EX (n = 24) and control groups, CON (n = 21). The EX group patients participated in a 16-week combined aerobic and resistance exercise program during dialysis. Bone markers including, FGF-23, klotho, fetuin-A, were measured before and at the end of the study in both groups. Statistical analysis for comparing data change during study by SPSS software and the P value was set at .05.

In the control group in the secondary assessment, reduction in quality of life was observed (P < .05). Significant change in growth factor 23, CRP, and fetuin-A was not observed in exercise and control groups (P > .05), however significant rising of klotho was observed in treated patients (P < .05). Also, combined training reduced the amount of phosphorus, parathyroid hormone; significantly (P < .05).

This study showed that regular exercise during dialysis improves quality of life and physical functions. No significant change in FGF-23 and CRP were observed during the study. However significant rising of klotho and reduction of iPTH and phosphorous levels were observed in treated patients.

Chronic obstructive pulmonary disease (COPD) is characterized by systemic inflammation and accelerated inflammaging of the lungs. Some studies showed that conjugated linoleic acid (CLA) has anti-inflammatory effects. The aim of the present study was to evaluate the effect of CLA supplementationon serum levels of interleukin (IL)-6 and sirtuin1 (SIRT1) in patients with COPD.

82 patients with stable COPD were enrolled in a double blind clinical trial. Subjects were randomly assigned to two groups: placebo (n=42) and 3.2 g CLA daily supplementation (n=40). Forced expiratory volume in one second (FEV1%), BODE index, and serum levels of IL-6, and SIRT1 were measured at the baseline and six weeks after the intervention. In addition, the study parameters in the two groups were compared based on the Global Initiative for Chronic Obstructive Lung Disease (GOLD) criteria.

After supplementation with CLA, serum levels of IL-6 and BODE index significantly decreased (p

Supplementation with CLA can modify the inflammatory markers and improve the health status of COPD patients. The results suggest that CLA supplementation in COPD patients can be useful in the management of the disease.

Certain salivary biomarkers that are considered unique in relation to the physiological aspects of periodontitis can be helpful in the diagnosis of periodontitis by considering quantitative changes in such biomarkers. This study was undertaken to answer the question to what extent non-surgical periodontal treatment can affect concentrations of salivary biomarkers in patients suffering from chronic periodontitis.

Eighteen patients with generalized moderate-to-severe chronic periodontitis were recruited for this study by considering periodontal parameters of gingival index (GI), probing pocket depths (PPD), clinical attachment levels (CAL) and a number of radiographic parameters. Salivary samples were analyzed at baseline and at one-month interval after non-surgical periodontal treatment consisting of scaling and root planing. Concentrations of salivary biomarkers, including cortisol, immunoglobulin A (Ig A), IL-6, interferon-γ, soluble intercellular adhesion molecule-1 (sICAM) and ALP, were determined with the use of an ELISA kit. Data were subjected to statistical analyses using paired t-test, with SPSS 15. Statistical significance was set at P<0.05.

Mean levels of IgA and interferon-γ decreased significantly after treatment (P<0.05); however, cortisol concentrations increased significantly after treatment. In addition, the decrease in IL-6, sICAM-1 and ALP levels were not significant (P>0.05).

The results showed that the salivary levels of IgA and interferon-γ decreased and those of cortisol increased significantly subsequent to scaling and root planing.

Hypercholesterolemia is a common metabolic disorder in developing and developed countries and is associated with the increased rates of chronic kidney disease (CKD). Statin therapy could reduce cholesterol synthesis as well as progression of CKD. Diversity between statins causes variety in pharmacokinetics and pharmacodynamics and also their pleiotropic effects. In the present investigation we aimed to evaluate the protective potentials of both atorvastatin (Ator) (as lipid-soluble statin) and rosuvastatin (Ros) (as water-soluble statin) against renal histopathological damages in the high cholesterol diet induced hypercholesterolemic rats (HCDIHR).

Serum lipid profile, oxidized low density lipoprotein (OX-LDL), malondialdehyde (MDA), urea and creatinine levels, as well as renal histopathology were evaluated.

While Ros acted better than Ator to reduce serum low density lipoprotein cholesterol (LDL-C) (P<0.01), atherogenic index (AI) (P<0.01), MDA (P<0.01), and OX-LDL (P<0.01); no significant differences were noted in their cholesterol (P=0.72), triglyceride (TG) (P=0.79), and very low density lipoprotein cholesterol lowering (VLDL-C) (P=0.79) and high density lipoprotein cholesterol elevating effects (HDL-C) (P=0.72). Ator was more effective to reduce renal histopathologic indices compared to Ros, including accumulation of lipid droplet, glomerular foam cells, mesangial cell proliferation, renal hemorrhage, and tubulointerstitial damages in the kidneys of diet induced hypercholesterolemic rats.

The findings underline that the lipophilic Ator may performs better than Ros in attenuating renal damages in HCDIHR.

This study evaluated the possible protective effects of Gordonia bronchialis (Gb) on oxidative stress and some subsequent alterations on testis from rats undergoing an experimentally induced type 1 diabetes.

A total of 40 male rats were randomly divided into four groups of ten. Diabetes was induced by injection of 55 mg/kg streptozotocin in 30 rats. Oral administration of Gb at dose of 105 (low dose) and 107 (high dose) CFU/rat was performed in two groups continuously for 14 days. The third and fourth groups received normal saline as the diabetic and healthy control groups, respectively. The blood and testicular tissue samples were taken on the 14th and 21st days post treatment for biochemical and histopathological evaluations.

Significant differences were found in blood glucose level, insulin, IL-6 and TNF-α values together with catalase and superoxide dismutase activities and malondialdehyde level in the diabetic group in comparison with healthy and Gb recipient groups. Moreover, the histopathological lesions observed in the diabetic rats mainly included basement membrane thickening, decreased number of Sertoli cells, and severe reduction of spermatogenesis markedly attenuated in Gb-treated rats.

Taken together, it seems that oral administration of Gb could ameliorate testicular damage associated with some related parameters in the diabetic animal model.

Hepatotoxicity—the most important side effect of the Methotrexate (MTX)—seems to relate to the generation of reactive oxygen species. Pomegranate has high anti-oxidant capacities. We studied if MTX-induced hepatotoxicity can be protected by pomegranate peel and seed methanolic extracts (PPE and PSE) in rats. Forty-eight Wistar rats were divided on the basis of: orally received normal saline as control, orally received 500 mg/kg PSE, orally received 500 mg/kg PPE, intramuscularly (IM) received 10 mg/kg MTX, MTX- and PSE-received, and MTX- and PPE-received groups. After the intervention, blood and liver samples were obtained. The results showed considerable antioxidant activity (510.7 ± 2.5 µg/ml) and total phenolic content (147.2 ± 0.2 mg GAE/g extract) of PSE and PPE, respectively. The ALT value reached the levels of the control group after treatment with PSE in PSE + MTX group. The serum level of ALT showed a significant increase in PPE+MTX group in comparison with MTX group. The results indicated that the PSE and PPE did not have considerable effect on ALP levels alone or together with MTX. Our results showed that PSE+ MTX and also PPE+ MTX treatment caused serum AST values to increase significantly in comparison with control and MTX groups. In histopatological study, the extracts decreased the pathological changes induced by methotrexate. The present study demonstrated that PPE and PSE that have notable total flavonoid and phenolic contents and also antioxidant activity, can protect the liver against histo-pathological and some enzymatic changes induced by MTX in rats.

Empagliflozin, a sodium-glucose cotransporter-2 (SGLT-2) inhibitor, possesses verified anti-inflammatory and anti-oxidative stress effects against diabetic nephropathy. The present investigation aims to examine empagliflozin effects on the renal levels of high mobility group box-1 (HMGB1), a potent inflammatory cytokine, and its respective receptor toll-like receptor-4 (TLR-4) in STZ-induced diabetic rats. Empagliflozin at 10 mg/kg per os (p.o.) was administered for 4 weeks, starting 8 weeks after the induction of diabetes. Renal function, kidney inflammation, oxidative stress, and apoptosis markers as well as renal HMGB1, receptor for advanced glycation end products (RAGE), and TLR-4 levels were assessed. In addition to down-regulating NF-κB activity in renal cortices, empagliflozin reduced renal levels of HMGB1, RAGE, and TLR-4. It alleviated renal inflammation as indicated by diminished renal expressions of inflammatory cytokines and chemokines like tumor necrosis factor-alpha (TNF-α) and monocyte chemoattractant protein-1 (MCP-1) and also decreased urinary levels of interleukin-6 (IL-6) and alpha-1 acid glycoprotein (AGP). Moreover, empagliflozin ameliorated renal oxidative stress as demonstrated by decreased renal malondialdehyde (MDA) and elevated renal activities of superoxide dismutase (SOD) and glutathione peroxidase (GPX). It also suppressed renal caspase-3, the marker of apoptosis; and furthermore, enhanced renal function noticed by the declined levels of serum urea and creatinine. These findings underline that empagliflozin is able to attenuate diabetes-related elevations in renal HMGB1 levels, an influential inflammatory cytokine released from the necrotic and activated cells, and its correspondent receptors, i.e., RAGE and TLR-4.

Molecular imaging is one of the import methods for recognition of cancer at the early stage in order to enhance the capacity of remedy. This study was aimed to introduce a new contrast agent that was targeted with CD24 so as to improve the CT scan detection of cancer cells with higher CD24 expression. The surface modifications of gold nanoparticles (Au-NPs) were done with long PEG (HS-PEG-CH3O) and short PEG (HS-PEG-COOH) chains to enhance their stability and capacity for immobilization of different antibodies. MTT assay was carried out to assess the biocompatibility of the NPs. The obtained contrast agent was implemented in the targeted CT imaging based on in vitro and in vivo studies of breast cancer. The results revealed that the attached CD24 to the cell surface of PEGylated Au-NPs could enhance significantly the cells CT number (40.45 HU in 4T1, while it was 16.61 HU in CT26) It was shown that the attenuation coefficient of the molecularly targeted cells was more than 2 times excessive than the control groups. Further, the tumor region in model of xenograft tumor has higher density compare to the omnipaque groups, 60 min after injection (45 Hu vs.81 Hu). These results showed that the nanoparticles stayed in tumor region for longer time. It is predicted that the synthesized nanoparticle can be used as computed tomography contrast agent. Also, it can be used to identify the tumor cells with higher expression of CD24 at the early stages more efficiently compare to the other routine methods.

Type 2 diabetes mellitus (T2DM) is related to the gut microbiota with numerous molecular mechanisms. Modulating the gut microbiota by probiotics could be effective in management of T2DM. The aim of the present trial was to evaluate the effect of Lactobacillus casei on glycemic control and serum sirtuin1 (SIRT1) and fetuin-A in patients with T2DM. Forty patients with T2DM (n = 20 for each group) were divided into intervention (probiotic) and placebo groups. The intervention group received a daily capsule containing 108 cfu of L. casei for eight weeks. The patients in placebo group took capsules containing maltodextrin for the same time duration. Anthropometric measurements, dietary intake questionnaires, and blood samples were collected, and the patients were assessed by an endocrinologist at the beginning and at the end of the trial. Fasting blood sugar, insulin concentration, and insulin resistance significantly decreased in probiotic group compared with placebo group (-28.32 [-50.23 to -6.41], 0.013; -3.12 [-5.90 to -0.35], 0.028; -32.31 [-55.09 to -9.54], 0.007, respectively). Moreover, HbA1c reduced after intervention, but the reduction was not significant (-0.45 [-0.96 to 0.05], 0.077). In comparison with placebo, the L. casei supplementation significantly increased SIRT1 and decreased fetuin-A levels at the end of the trial (0.52 [0.026 to 1.02], 0.040; -17.56 [-32.54 to -2.58], 0.023, respectively). L. casei supplementation affected SIRT1 and fetuin-A levels in a way that improved glycemic response in subjects with T2DM. Affecting the SIRT1 and fetuin-A levels introduces a new known mechanism of probiotic action in diabetes management.

Cisplatin (Cis) is a chemotherapeutic agent and nephrotoxicity is a serious adverse effect of the drug. This study investigated the protective effects of Cornus mas fruit hydro-methanolic extract (CME) on cisplatin-induced nephrotoxicity in a rat model.
Forty Wistar rats were divided into the control group, CME group, CME 300 Cis group, CME 700 Cis group, and Cis group. After the intervention samples were taken for biochemical and histopathological analysis.
The CME analysis showed considerable total antioxidant and total phenol contents. The blood serum urea and creatinine increased (p 0.05). The renal MDA levels of the Cis and CME 300 Cis groups decreased significantly in comparison to the control and the CME groups (p The results showed renoprotective effects of CME against Cis-induced nephrotoxicity in rats.

Cisplatin (Cis) has serious adverse side-effects that limit its clinical use. The mechanism underlying the effects is complex, including mitochondrial oxidative stress and inflammation. This study investigated whether Cornus mas, a fruit with high antioxidant contents, hydro-methanolic extract (CME) can modulate the cisplatin-induced changes. Forty Wistar rats were divided into a control group, Cis group, CME group, CME 300 Cis group, and the CME 700 Cis group. After the intervention, blood samples were taken for biochemical and hematological analysis. CME analysis showed noticeable total phenol and total antioxidant contents. The plasma glutathione peroxidase and catalase levels were significantly decreased and malondialdehyde and blood hemoglobin levels were significantly increased in the Cis group, which were reversed to the control levels in the CME Cis groups. In the CME group, the red blood cell count was significantly lower and the red cell distribution width and hemoglobin distribution width levels were significantly higher. In the Cis-treated group, white blood cells, neutrophils, monocytes, basophils, and large unstained cells were significantly increased and lymphocytes were significantly decreased when compared with the control group that was reached to non-significant levels in CME 700 Cis group. The blood cholesterol and high density lipoprotein in all CME-treated groups were significantly decreased. The eosinophils increased in the CME group significantly. The results showed considerable total antioxidant and total phenol contents and relative protective effects of CME against Cis-induced antioxidant and hematologic changes in rats.

Despite progress in the control and treatment of gestational diabetes mellitus (GDM) in pregnant females, these patients remain at risk of disease complications.
The present study aimed at investigating the effect of probiotic supplements on Systolic Blood Pressure (SBP) and Diastolic Blood Pressure (DBP) in pregnant females diagnosed with GDM.
This randomized double-blind, placebo-controlled trial randomly assigned 64 pregnant females with GDM, recruited through convenience sampling, to either a group receiving a probiotic capsule (n = 32) or a group receiving a placebo (n = 32) for 8 weeks in Tabriz, Iran, during the spring and summer months of 2014. Their blood pressure was measured at baseline and at 2-week intervals, up to 8 weeks.
A total of 56 subjects completed the study. There was no significant difference in SBP in the probiotic group at any time compared with that at onset, yet, SBP increased significantly in the placebo group. The declining trend of DBP was evident in the probiotic group at 2 weeks and continued to the end of the study; however, DBP had increased slightly by week 6 in the placebo group. There were significant differences between the probiotic and placebo groups at 6 and 8 weeks, respectively, for SBP (104.828 (2.051) mmHg vs. 112.963 (2.126) mmHg; P = 0.008) and (106.552 (1.845) mmHg vs. 115.185 (1.912) mmHg; P = 0.002) and for DBP (62.414 (1.353) mmHg vs. 70.741 (1.402) mmHg; P The results demonstrated that consumption of probiotic supplements for 8 weeks prevented an increase in SBP and decreased DBP in pregnant females diagnosed with GDM.

Methotrexate (MTX) is prescribed in many diseases and can result in oxidative stress (OS) followed by injuries in some tissues. Antioxidants administration are effective in reducing OS. Pomegranate exhibits high anti-oxidant capacities. This study investigated whether pomegranate seed and peel methanolic extracts (PSE and PPE) could protect against MTX-induced OS and lipid profile changes in rats.
Forty-eight rats were randomly divided into 6 groups: control group (normal salin), PSE group (500 mg/kg, orally), PPE group (500 mg/kg, orally), MTX group (10 mg/kg, IM), MTX and PSE group, and MTX and PPE group. Blood samples were taken for analysis in the end of the procedure.
The findings showed a significant reduction in Glutathione peroxidase (GPx) and Superoxide dismutase (SOD), and an enhancement in malondialdehyde (MDA) values after MTX treatment (p The results showed the OS induced by MTX and the protective effects of PSE and PPE against MTX-induced serum oxidative stress and lipid profile changes in rats.

Nanostructured lipid carriers (NLCs) composed of solid lipid and oil are a new generation of lipid nanoparticles which have exhibited some merits over traditional used lipid nanoparticles in fortifying food and beverages and nutraceuticals delivery systems such as liposomes and solid lipid nanoparticles.
In this study, Precirol and Compritol as solid lipids, Miglyol and Octyloctanoat as liquid lipids, Tween80, Tween20 and Poloxamer407 as surfactants were used to prepare vitamin D3-loaded NLC dispersion using hot homogenization method. The particle size and size distribution for all formulations were evaluated by immediately after production and during a storage period of 60 days.
The Precirol-based NLC showed superiority over Compritol-based NLC in the point of physical stability. Results clearly suggested that an optimum concentration of 3% of Poloxamer407 or 2% of Tween20 was sufficient to cover the surface of nanoparticles effectively and prevent agglomeration during the homogenization process. Octyloctanoat was introduced for the first time as a good substituent for Miglyol in the preparation of NLC formulations. The vitamin D3 Intestinal absorption enhanced by the incorporating in NLCs.
It was concluded that NLC showed a promising approach for fortifying beverages by lipophilic nutraceuticals such as vitamin D.

Methotrexate (MTX), as one of the most pivotal drugs in treatment of some malignancies and autoimmune diseases, is associated with damages to different tissues particularly the liver tissue through impairing the balance between antioxidant and pro-oxidants. Pomegranate peel is a great source of polyphenols with antioxidant function that has recently become a center of attention.
The current study was undertaken to investigate the effects of MTX and pomegranate peel methanolic extract (PPME), alone and in combination, on liver antioxidants of rats.
Antioxidant capacity, total phenolic and flavonoid contents of PPME were analyzed. 32 rats were divided into (1) control, (2) orally received 500 mg/kg PPME, (3) intramuscularly received 10 mg/kg MTX, and (4) PPME (for 18 days) and MTX (for 3 days beginning from the 10th day) groups. After the experimental period, the rats were euthanatized and tissue samples were obtained for antioxidant analysis.
PPME had a considerable antioxidant capacity, as well as total phenolic and flavonoid contents. There were low liver contents of Glutathione peroxidase (GPx) and Catalase and a high level of Malondialdehyde and Superoxide dismutase (SOD) in the Methotrexate group compared to the control group (P Methotrexate can surprisingly increase SOD and Malondialdehyde and decrease Catalase contents. PPME can decrease GPx and relatively prevent the effects of Methotrexate on SOD and Catalase contents of the liver tissue. However, further studies are recommended.

Statement of the Problem: Various researchers have suggested the use of β2-adrenergic receptor antagonists in prevention or treatment of bone resorption.
This study aimed to evaluate the effect of β2-adrenergic receptor antagonists on number of osteoclasts and osteoblasts involved in the healing of extraction socket of maxillary first molar in rats.
Maxillary first molars of 40 rats were extracted and divided into two groups. The test group received 0.1 mg/kg propranolol intraperitoneally daily. The controls received normal saline. At days 7, 14, 21 and 28 post-extraction, 5 rats were euthanized from each group. Maxillary bone was resected and the mean number of osteoblasts and osteoclasts in tooth socket was measured.
After 1 week, the number of osteoclasts in the controls was significantly higher than the test group. A significant increase in the number of osteoclasts in both groups at week 1 was observed compared to the following weeks (p β2 adrenergic receptor antagonists decrease the number of osteoclasts and increase the number of osteoblasts during extraction socket healing.

This paper1 was simultaneously submitted by the authors to "Transplantation" journal under the title "The Effects of Valsartan on Renal Klotho Expression and Oxidative stress in Alleviation of Cyclosporine Nephrotoxicity" and was accepted for publication in that journal. On the basis of BioImpacts policy in accordance with the Committee on Publication Ethics (COPE), any duplicate submission is considered as an ethical misconduct. The accepted manuscript in Transplantation shared considerable overlapping text and data (identical images and materials) with the published paper1 in BioImpacts. The Editor-in-Chief of BioImpacts, Prof. Y. Omidi, was alerted by the Editor-in-Chief of Transplantation, Prof. Jeremy R. Chapman, on such duplication. A comprehensive investigation through comparison of both papers was conducted by the editorial office of BioImpacts along with the Ethics Committee of Tabriz University of Medical Sciences (TUOMS) under Prof. M. R. Rashidi, who also acts as Director-in-Charge of BioImpacts and TUOMS Vice Chancellor of Research and Technology Affairs. As a result, they decided to retract this paper in line with the COPE recommendations. The authors were informed and advised on this serious ethical breach. Therefore, the paper is retracted at the request of authors, the aforementioned committee and the Editor-in-Chief of BioImpacts, even though the corresponding author believed that two papers were different in their aims, studied animals, and factors. By the way, they apologize for any inconvenience this may have caused. One of the conditions of submission of a paper to BioImpacts is that authors declare explicitly that "This manuscript has been exclusively submitted to this journal and is not under review or accepted for publication elsewhere". As such, this paper represents abuse of the scientific publishing system. As a peer-review multidisciplinary international "Publish Free" and "Access Free" journal, BioImpacts strongly adheres to the "Publication Ethics", and its foremost goal is to preserve the integrity of the scientific reports in the highest standards, therefore the journal takes all issues of publication misconduct seriously.
