Context:

 The skin is the most important organ of the body, and maintaining its integrity is important for health. Severe skin damage is life-threatening, and wound healing restores its integrity. One of the main health problems is impaired cutaneous wound healing. According to the importance of wound healing and the fact that unrepaired skin decreases the quality of life, many studies have investigated the effect of some natural and chemical substances on the length and quality of wound healing to find beneficial interventions for rapid and economical treatment.

 This review was conducted to describe the physiology of cutaneous wound healing and some positive and negative factors affecting it with a focus on exercise.

 An electronic search without any time limitation was performed on the PubMed, Google Scholar, and Web of Science databases. The keywords were ‘wound’, ‘healing’, and ‘exercise’. Finally, according to the similarities or differences between the results and the relationship with the subject, 53 papers were selected and reviewed.

 Wound healing is a complex physiological process with four overlapping processes. It seems that disturbance in the inflammatory phase of wound healing is the main factor in the impairment of healing. Traditionally, many chemical and herbal medicines and compounds have been used to speed up wound recovery due to their anti-inflammatory and antioxidative properties. Many studies have evaluated the effect of exercise, as complementary medicine, on wound healing, and they have examined the effect of different protocols of exercise on the speed of wound healing. According to the results of these studies, aerobic exercise, due to its anti-inflammatory and antioxidative effects, is a beneficial method in shortening the length of healing, especially in aged, obese, and diabetic individuals.

 Exercise as a low-cost intervention is a good strategy in the treatment of impaired and chronic wounds.
 

 The mandibular bone is affected by age, metabolic activity, and hormonal changes.

 This study aimed to determine the sex determination using the mandibular angle in the adult population of Iran.

 This cross-sectional study enrolled 149 patients (73 men and 76 women) referred to the 600 Army Dental Center in 2016. Graphics were obtained from cephalogram and panorex using a Soredex digital device and Pack software to measure mandibular angles.

 The mean mandibular angle was 122.19 ± 3.89 in men and 124.72 ± 3.24 in women, with a significant difference based on the independent t test (P < 0.05).

 It seems that the mandibular angle is higher in women than in men.

 Tattoos or stencils on the body have a special charm for the people of different cultures. The fact that such stencils are considered attractive and essential to some people from a specific culture has led to the conclusion that there might be factors which make tattooing attractive to someone.

 The present study aimed to determine and compare behavioral activation system (BAS), behavioral inhibition system (BIS), and fight-or-flight system between tattooed and non-tattooed substance-dependent individuals.

 Using convenience sampling method, this study included 146 substance-dependent individuals (73 tattooed and 73 non-tattooed) referring to Baharan rehabilitation center in Zahedan, Iran. Data collection was done by the short form of the Gray–Wilson Personality Questionnaire (GWPQ), and data were analyzed by independent t-test.

 According to the results of GWPQ, in BIS, in tattooed individuals, extinction and total scores of avoidance was significantly higher than non-tattooed. Meanwhile, there was no significant difference between BAS and fight-or-flight system.

 While BAS is associated with positive emotions, BIS is associated with negative emotions. The tattoo seems to be a sign of special personality characteristics and can be used as a way to extinction the emotions and avoiding to deal with pejorative emotions.

 Following the emergence of the new coronavirus pandemic, e-learning seemed to be the first and best alternative to classroom-based medical education. The Learning Management System (LMS) is a key infrastructure requirement for the provision and progression of e-learning.

 This brief report is about a team-based e-learning method for clinical education in the COVID-19 pandemic.

 A novel e-learning protocol was implemented for the instruction of knowledge-based part of practical operative dentistry course to third- and fourth-year dental students in NAVID LMS, and their satisfaction levels were evaluated.

 More than 90% of the students mentioned that the method encouraged them to learn new topics and created a joyful learning experience for them. More than 80% reported that the method decreased their anxiety for learning practical topics during the COVID-19 pandemic.

 Implementation of such a team-based e-learning method can greatly help in the instruction of clinical topics.
 

 A bioresonance-based complementary treatment for corneal ulcers is described to determine whether an electromagnetic field can improve intractable corneal ulcers.

 The patient was a 65-year-old man who was suffered from corneal ulcer. The wound was burned five times with laser surgery; however, there was no significant improvement in the patient's condition. He had been treated for a year with electromagnetic frequency complements.

 Since bioresonance therapy can heal the corneal ulcer in this patient, we advised patients to perform this treatment.

Nocturnal enuresis is a symptom defined as enuresis in children with higher than 5 years of age that might have mutual connection to sleep disturbances. This condition might be a stressful factor for children and their families.

This study aimed to find the correlation between primary monosymptomatic nocturnal enuresis (PMNE), as a stressful factor and sleep disorders.

This case-control study was conducted on 132 children, including 66 children with nocturnal enuresis as the case group and 66 healthy children as the control group. The two groups were homogenous in age, gender, and other demographic characteristics. The organized sleep disorder questionnaire based on sleep disorder diagnostic criteria (using the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision) was used in this study. The correlation between PMNE and sleep disorders was investigated based on the Chi-square test on SPSS software (version 23).

The mean scores of the subjects with sleep disorders in the control and case groups were 0.38 ± 0.78 and 2.24 ± 1.73, respectively. Therefore, there were significant differences between the two groups in sleep disorders (P = 0.001). In addition, primary insomnia, hypersomnia, circadian sleep rhythm, and sleep terror disorders in the case group were higher than the control group (P = 0.001).

The PMNE has been defined as a risk factor for sleep disorders.

The reliable and easy-to-operate detection of hydrogen peroxide (H2O2) has attracted extensive attention in the fields of biomedicine, food security, and environmental analysis.

In this work, a novel electrochemical method was proposed for H2O2 monitoring using a carbon paste electrode (CPE) modified with MnO2/sepiolite nanocomposite.

MnO2/sepiolite material was characterized by transmission electron microscopy (TEM), energy-dispersive X-ray spectroscopy (EDS), and X-ray diffraction (XRD) technique. The modified CPE was employed for the amperometric monitoring of H2O2 in human serum samples.

Electrochemical data showed that the MnO2/sepiolite-CPE displays a high peak current towards H2O2 oxidation. A linear range from 5 to 700 μM and a low detection limit of 0.8 μM for H2O2 were obtained with the proposed sensor. Besides, the electrode depicted excellent reproducibility and anti-interferant ability, promising the applicability of this electrochemical method in practical analyses.

This work introduced a new and effective enzyme-less H2O2 sensor based on the MnO2/sepiolite nanocomposite modified CPE. The suggested sensor showed good sensitivity for the rapid detection of H2O2 in a wide linear range with a low detection limit and satisfactory reproducibility, which made it practical for the analysis of hydrogen H2O2 in real samples.
