For many years HbA1c used as diagnostic criteria for diabetes, however, measurement of HbA1 has some limitations that cannot be accurately assess blood glucose levels in conditions such as changes in red blood cell life. in this study, we evaluated and compared the levels of HbA1C in diabetic, pre-diabetic and non-diabetic individuals to understand the role and relationship of different values of RBC`s indices in these conditions.

This study performed between august to December of year 2021, and the demographic information and hematologic indices of 706 individuals which referred to laboratories in Gorgan city were investigated. According to results of FBS and HbA1c, individuals categorized in three distinct healthy (H), pre-diabetic (PD), and diabetic (D) groups base on latest ADA criteria.

Evaluation of HbA1c level based on the presence or absence of anemia showed that in diabetic group with anemia significantly had a lower level 8.4 (± 1.5) than people without anemia 8.6 (± 1.5) (P= 0.045).

In this study, it was shown that changes in RBC indices in anemia can lead to inaccurate measurement of HbA1c level.

Leishmania Species produced diseases include clinical problems from cutaneous self-limiting to severe non-healing forms such as visceral leishmaniasis (VL). As an obligatory intracellular parasite these pathogens proliferate and survive inside macrophages in animals and human; while these cells as a major host immune cell destroy majority of disease producing agents. Because macrophages act as first line of innate immunity, produce several molecules when activated. Proinflammatory and inflammatory cytokines are produced by these cells through their activation, act as main coordinators of the immune system against pathogens and other harmful disease producing factors against the body. Through such a mechanism the immune response resolves the problem.  To play such a critical role many cells as monocytes, macrophages, DCs and others involved in T cell regulation to establish proper innate and adaptive immunity responses. Proinflammatory and inflammatory cytokines are produced in a network acting through many signal pathways. In this descriptive designed study, quality-controlled cDNA samples sequenced (RNA-seq) and mapped against a standard human genome version. Based on the results of this study, proinflammatory and inflammatory gene expressions were significantly upregulated. Upregulations of proinflammatory and inflammatory gene expressions early infection time might be indication for an early  innate immunity response.

Cutaneous leishmaniasis is endemic in most areas of Iran, and the diagnosis of its species is essential for controlling the disease. Leishmania major is the causative agent for cutaneous leishmaniasis in humans. Molecular methods are generally more sensitive than microscopic methods. The present study aimed to use a polymerase chain reaction-enzyme linked immunosorbent assay (PCR-ELISA) technique for detecting live L. major from wounds of patients with cutaneous leishmaniasis.

In the present study, a standard strain of L. major promastigotes was used as the positive control for purification of DNA. The Novy–MacNeal–Nicolle and RPMI-1640 media were used for reproduction of parasites. DNA was isolated from specimens taken from 35 patients with suspected cutaneous leishmaniasis whose disease was confirmed by direct smear method. The PCR-ELISA technique was later applied by using the standard strain, patient specimens, and primers specific for the 18s rRNA.

Out of 35 patients, 17 (48.6%) were male and 18 (51.4%) were female. In addition, 8.6% of the patients lived in the Gonbad-e Kavus County, while all patients had been infected in villages around Gonbad-e Kavus. Of 35 patients with confirmed cutaneous leishmaniasis according to the direct smear method, 31 patients (86.31%) had leishmaniasis based on the PCR method and the PCR-ELISA methods.

Based on the results, the PCR-ELISA method is more sensitive and accurate for detecting L. major.

Leishmaniasis is caused by members of the Leishmania species and constitute a group of infective diseases that range from cutaneous lesions to lethal visceral forms. In infected persons, macrophages recognize and eliminate the parasites via phagocytosis. In order to change a hostile environment into an environment adequate for survival and reproduction, the engulfed Leishmania species needs to modulate the function of its host macrophage. The expression patterns of cytokine genes such as interleukin-12 (IL-12), tumour necrosis factor-alpha (TNF-α), IL-1, and interferon-gamma (IFNγ) represent the immune response. In this study, we employed an RNA-seq approach for human monocyte-derived macrophages infected with Leishmania major (L. major) to decipher cytokine gene expression alterations in host macrophages.

In this descriptive study, human monocytes were isolated by magnetic activated cell sorting (MACS) and cultured in the presence of monocyte colony stimulating factor (M-CSF) to obtain the macrophages. Monocyte-derived macrophages were then co-cultured with metacyclic promastigotes of L. major for 4 hours. RNA isolation was performed using TRIzol reagent. RNA sequencing was performed using the Illumina sequencing platforms. Gene expression analysis was performed using a Bioconductor DESeq2 package.

Our data revealed significant changes in immune response gene expressions in macrophages infected with L. major, with an up-regulation of cytokines and mostly down-regulation of their receptors.

The obtained data could shed more light on the biology of L. major and how the host cell responds to leishmaniasis.

Human T-cell lymphotropic virus type-1 is an oncornavirus that causes adult T cell leukemia (ATL) HTLV-I-associated myelopathy⁄tropical spastic paraparesis (HAM/TSP). Golestan province is located in North West of Khorasan province known as an endemic area for HTLV-I in Iran. This study aimed to evaluate seroprevalence of HTLV-Iin Golestan province. In this cross-sectional descriptive study in 2007, blood samples were collected from 2034 healthy people residing in different parts of Golestan province. Sera were assessed for HTLV-I/II–specific antibodies by ELISA method and reactive samples were confirmed by Western blot. Demographic and serologic data were entered in SPSS version 11.5 and statistical analysis was performed. An overall HTLV-I/II prevalence of 0.7% was observed in 15 cases by ELISA. Six out of 15 were confirmed as HTLV-I by western blot. Regional variation in the prevalence of HTLV-I was observed; 0%, 0%, 0.1%, 1.9%, 0.3%, 0%, and 2.6% tested HTLV-I-positive from west to east of Golestan Province regions, respectively. Seropositivity increased with age. No association between HTLV-I infection and sex status was detected. Highest rate of HTLV-I seroprevalence was shown in east of this region located in neighborhood with Khorasan province, the only confirmed endemic area in Iran. It seems that eastern area of our province is endemic for HTLV-I. Further comprehensive detailed epidemiological and molecular studies are recommended.

Colorectal cancer is the third common malignancy in the world. Personal habits including life style and nutrition have been proposed as risk factors of colorectal cancer. We conducted this study to assess the nutritional characteristics in colorectal cancer patients in Golestan province of Iran.

This case-control study was done on 47 colorectal cancer cases, diagnosed during 2004-05 and 47 healthy controls. A questionnaire containing socio-demographic and nutritional characteristics (FFQ) was filled for each of the participants. Chi square test was used to assess the relationship between variables.

In each of the two groups, 40.4% were females and 59.6% were males. The mean±SD age of age in cases and controls were 52.4±13.4 and 52.1±13.1 years, respectively. Total energy expenditure of higher than 1837.5 Kcal/ day was significantly related to colorectal cancer (OR=3.8 95% CI: 1.2-11.3). Colorectal cancer risk was higher in individual with frying cooking method (OR=3 95% CI: 0. 8-11.1). The risk of colorectal cancer was 6.5 times higher in individuals with fat consumption of higher than 118.5 grams/day (95% CI: 1.5-28.8). No significant relationship was seen between vegetables consumption and the risk of colorectal cancer.

This study showed that high total energy expenditure, high fat consumption and using frying method for cooking are risk factors of colorectal cancer in Golestan prevince in Nothern of Iran.

Hepatitis B virus (HBV) infection is one of the most important health problems all over the world. This study was conducted to determine the co-infection of hepatitis C virus (HCV), hepatitis D virus (HDV) in HBV infected patients in Golestan province of Iran. This population based cross sectional study was done in 2004. 139 HBsAg positive cases were assessed for co-infection with HCV and HDV. Serologic tests were done by ELISA method using available kits. Data were analyzed by SPSS-12 and STATA8 software. P-values of less than 0.05 were considered as significant. Sixty eight (48.9%) of 139 cases were males and 71 (51.1%) were females. The mean (±SD) of participant's age was 41.89 (±11.3) years (range: 25-64 years). Anti-HCV and Anti-HDV antibodies were positive in 17 (12.3%) and 8 (5.8%) cases, respectively. Females were more infected with HCV and HDV than males. But the differences were not significant. The prevalence of co-infection with HCV and HDV in HBV infected cases is relatively high and notable in Golestan province of Iran. Because of negative effects of these co-infections in clinical outcome of the disease, it is recommended to assess possible HCV and HDV infection in individuals with HBV infection. This may result in more efficient management of the disease.

Foot ulcers are common in 12-25 percent of diabetic patients. Preventing, controlling and treating of these kind chronic wounds are of the major clinical challenges.Evidence based documents revealed that DFU (Diabetic Foot ulcer) is a chronic wound type originating from disturbed cellular and molecular mechanisms that have to be in its functional form to overcome its problem. In diabetes and some other chronic based diseases, harmonized acting machine causes chronic phases that result in conditions as foot ulceration and related complications seen commonly in diabetes.DFU needs to be transformed into acute phase in order to be healed in a physiological manner. Disturbed mechanisms have to be corrected reversely and to achieve such a goal it is essential to better understanding of disturbing factors responsible for biological abnormalities. Factors associated with DFU are as cellular and molecular recruitment and function impairments and there is need to repair these mechanisms. For this, we believe that the activated Th-1 cells (T helper-1 Cells) might have a critical role in regulation of the several effector functions of the cellular and molecular mechanisms essential to the body to act the best. Evidences and our successful results urge us to suggest this regulatory role for effector cells and molecules generated through activation of Th-1 cells as a treatment strategy.
