Abstract
Background and Aim: Body image is one of the main factors of self efficacy. This study aimed to investigate the relationship between body image and self-efficacy among female students in Hamadan University of Medical Sciences.
Methods: This cross-sectional study was carried out on 408 female students of Hamadan University of Medical Sciences in 2017 with a stratified sampling method. To gather data, we used Multidimensional Body Self-Relation Questionnaire (MBSRQ) and general self-efficacy questionnaire and recorded demographic variables. Data were analyzed with SPSS-21 software using Pearson correlation and linear regression tests.
Results: The dimensions of body areas satisfaction and illness orientation were evaluated at relatively desirable and moderate levels, respectively. Students' self-efficacy was also estimated at 60.05% of the mean score of the maximum achievable score at the moderate level. The results of regression analysis showed that the dimensions of the illness orientation, overweight preoccupation, fitness orientation, self-classified weight and appearance evaluation predicted the self-efficacy among the female students. In total, different dimensions of body image explained 14.1% of the variance of self-efficacy.
Conclusion: We suggest providing training packages about body image dimensions improvement to enhance the self-efficacy of university female students.

Abstract
Background and Aim: Patients with systemic lupus erythematosus do not have a flexible approach against stress and have difficalty regulating their cognitive skills performance. The aim of our study was to evaluate the impact of cognitive-behavioral group therapy on reducing perceived body image stress and improving cognitive flexibility among women with systemic lupus erythematosus.
Methods: In this research, 24 women referred to rheumatology clinics in Mashhad between the years 2015 and 2016 were selected and randomly assigned into two experimental (cognitive-behavioral group therapy) and control groups. Before and after interventions, Body Image Concern Inventory (BICI), Cognitive Flexibility Inventory (CFI), Client Satisfaction Questionnaire (CSQ) and Clinical Global Improvement Scale (CGI) were filled out for both groups. The data was analyzed using multivariate analysis of variance (MANOVA) in SPSS-19 software with the significance level of 0.05. Further, percentages of improvement were calculated.
Results: Cognitive-behavioral group therapy compared to the control group led to a significant reduction in body image concern, and improvement of cognitive flexibility (P<0.001). The level of treatment satisfaction and overall improvement were significantly higher in intervention group and the improvement in all the research variables were more than those of the subjects in the control group (P<0.001).
Conclusion: Cognitive-behavioral group therapy was effective in reducing body image concern and improving cognitive flexibility in women with systemic lupus erythematosus.

Abstract
Background and Aim: The cosmetic surgery is one of the prevalent phenomenons in recent decades. Body image is a key factor for interest in cosmetic surgery, but body image is a multidimensional concept and all its dimensions should be studied. This study aimed to study cognitive, emotional and behavioral dimensions of body image in women interested in cosmetic surgery.
Methods: This study was a cross-sectional research with causal-comparative method. A sample of 600 female students, age 18 to 35 years, were selected from universities in Tehran by using multi-stage cluster random sampling methid, who completed a set of questionnaires including “Beliefs About Appearance Scale (BAAS)“, “Body Areas Satisfaction Scale (BASS)“, “the Body Image Coping Strategies Inventory (BICSI)“ and Acceptance of Cosmetic Surgery Scale (ACSS). The collected data were analyzed by multivariate analysis of variance (MANOVA).
Results: The students who were interested in cosmetic surgery got a higher score in components of body investment as cognitive dimension and body dissatisfaction as emotional dimension. Among the three behavioral components of body image, there was significant difference only in appearance fixing coping (P<0.0001) and there were no significant differences in acceptance and avoidant strategies between students.
Conclusion: All of the cognitive, emotional and behavioral dimensions of body image are important in cosmetic surgery, and women interested in cosmetic surgery not only had body dissatisfaction, but also had dysfunctional attitudes about appearance important in interpersonal relationships, personal achievement and self-concept, and used strategies based on body modification. These findings can be used in prevention and intervention programs.

Abstract
Fungi are eukaryotic organisms that potentially have the ability to cause disease in humans and animals. Fungal infections are called mycosis, which are divided into four types of superficial, cutaneous, subcutaneous and systemic, depending on the area of the body involved. Though cutaneous mycoses are rarely life-threatening infections, they can isolate the patient socially due to the disfigurement of the tissues they caused, as a result of which, treatment has always been an important issue. On the other hand the similarity of fungi to mammalian cells led to difficulties in the development of novel antifungal drugs. Consequently, in recent years, extensive efforts have been made to design and develop novel drug delivery systems with better efficacy for drug delivery of conventional anti-fungal drugs. In this study, we compared conventional forms and novel drug delivery systems of a number of antifungal drugs. All studies confirm the relative priority of novel drug delivery systems to conventional forms in terms of penetration, release, and antifungal effects.

Abstract
Background and Aim: The aim of this study was to investigate the relationship between perfectionism and depression with body image in women asking for cosmetic surgery.
Methods: In this study 360 women (20-40 years old) asking for cosmetic surgery (nose and chest) in north of Tehran in year 1397 were selected by convenience sampling. The questionnaires that were used included multidimensional perfectionism in Tehran (2007), Beck depression (BDI-II 1996) and body image (MBSRQ 1983) and to analyze the findings, multi-variant regression analysis and Pearson correlation coefficient were used.
Results: The results showed there is an inverse relationship between perfectionism and body image. That means higher perfectionism shows that the body image is weaker. Also there is an inverse relationship between depression and body image. That means higher depression shows that the body image is weaker. There is a direct relationship between perfectionism and depression. That means high perfectionism in subjects shows that depression is high in them (P<0.05).
Conclusion: Perfectionism and depression can predict the body image, perfectionism prediction was stronger, as it had a higher beta value than depression.

Abstract
Superficial dermatophytoses are among the most common infectious disease. The most commonly used antifungal categories reazoles, polyenes and echinocandins. Due to the limited number of available antifungal drugs, toxicity and the emergence of resistant (intrinsic or acquired) strains, antifungal strategy needs to be developed. Recently the researchers try to find alternative antifungal agents. This review emphasizes the action and resistance mechanisms to antifungal drugs, the search for new agents, drug- resistant genes, and the application of combination therapy and immunomodulators (using cytokines and gamma interferon which can provide novel insights to fighting fungal infections). A comprehensive review study was performed using the keywords including Candida, antifungal drugs and drug resistance in valid medical databases, mainly PubMed. Articles that were most relevant to the purposes of the study were selected and studied. Problems with antifungal resistance and the emergence of resistant strains of fungal has produced an enormous demand for new antifungal agents. The clinical complexity of patients with resistant mycoses prevents an easy approach to the detection, prevention, and management of antifungal drug resistance. Continuing investigation will illustrate the role of susceptibility testing for resistant mycoses and on clinical strategies used to fighting antifungal drug resistance in pathogenic fungi.

Abstract
Introduction: Dermatophytosis are micro-organisms which can lead to skin diseases. In rare occasions they can have atypical skin manifestations, which could result in delay in diagnosis.
Case Report: A 20-year-old Iranian boy was referred to our center with a 5-month history of circular, symmetrical, itchy crusted skin lesions on his groin. Direct microscopy, culture test and PCR-sequencing of ITS regions of the rDNA gene were conducted and showed T. indotinea as the causative agent. Based on antifungal susceptibility test oral pulse therapy with itraconazole 100 mg twice daily for 1 week combined with topical clotrimazole cream for 1 month was initiated, which cleared the lesions.
Conclusion: This case report is of significance since T. indotinea produces atypical skin lesions, as well as, multidrug resistance to antifungal agents.

Methods: In this cross-sectional study, 1419 men over 35 years from 32 provinces participated by invitation. Demographic information, underlying disease history and presence of skin problems/diseases were collected by dermatologists. The participants were evaluated in terms of the presence of skin complaints (itching, burning, dry skin, redness, scaling, and skin color change); and any skin complaints with type, severity and location.
Results: About one third 31.6% of the Iranian male middle-aged and elderly, had an underlying disease (n=449). High blood pressure, diabetes, and neurological disorders constituted 79.7% of the chronic diseases. In total, n=344 persons (24.2%) were rated as having skin complaint. Most people who had a skin complaint reported more than one skin complaint 75.6% (n=260). The most common skin complaints were related to itching 14.6% (n=207) and dry skin 5.6% (23.3%) in studied population, which were mostly mild 59.3% (n=204) and localize 58.4% (n=201). The use of corticosteroids was stated in 7.2%(n=103) and the most common types of usage was oral 62.1% (n=64). There was significant correlation between skin complaint and occupational exposure (P=0.01); lower education level (P=0.05); corticosteroid usage in general (P<0.001) and both oral (P=0.02) and topical (P<0.001) corticosteroid.
Conclusion: Skin complaint is common among middle-aged and elderly Iranian men. The most common skin complaint are mostly mild and localized itching and dry skin.

Abstract
Background and Aim: Oral hydrolyzed collagen is one of the newest and most popular systemic supplementations for skin rejuvenation. However, there are limited information in case of Middle Eastern consumers. The purpose of this study was to evaluate the tolerability and efficacy of an oral collagen supplement for improvement of skin elasticity, hydration and roughness.
Methods: It was a 12-week, before-after clinical study, conducted on 20 participants (18 women and two men) aged 44.15±5.36 years with skin type III-IV. Skin elasticity parameters (R0, R2, R5 and R7), skin hydration and friction, as well as the thickness and echo density of the dermis, were measured after six and 12 weeks daily intake of the study product, as well as four weeks after stopping its use (week 16). Participants’ satisfaction was assessed on the basis of their answers to the standard questionnaire, and tolerability of the product was assessed by monitoring the adverse effects.
Results: A significant improvement was detected in R2, R5 and skin friction at week 12 (P<0.041, P<0.012 and P<0.01, respectively). At week 16, the values remained at an increased level, which indicates the stability of the results. The increase of dermis density in week 16 was also significant (P=0.03). Moderate overall satisfaction was reported with the treatment, and a few gastrointestinal complications were reported.
Conclusion: The study demonstrated that oral collagen peptides could significantly improve the skin elasticity, roughness, and dermis echo density, and they also proved to be safe and well-tolerated.

Abstract
This review study examines the effects of oral collagen supplementation on various biophysical properties of the skin, including hydration, elasticity, and wrinkle reduction. Collagen, as the most abundant structural protein in the skin, plays a vital role in maintaining its firmness, elasticity, and moisture. With aging, collagen production declines, leading to visible signs of aging such as wrinkles, sagging, and dryness of the skin. Additionally, factors like UV radiation and environmental pollutants accelerate collagen degradation, contributing to premature skin aging. In recent years, oral supplements containing hydrolyzed collagen, particularly collagen peptides, have gained significant popularity due to their potential ability to stimulate collagen production and improve skin quality. Various studies indicate that regular consumption of these supplements can significantly increase skin hydration, enhance elasticity, and reduce the depth and number of wrinkles. However, there are notable limitations in the existing studies, including variations in dosage, intervention duration, and collagen sources. Moreover, many of these studies have small sample sizes and short intervention periods, which limit the validity of the results. Additionally, the presence of other ingredients, such as vitamin C and hyaluronic acid in some supplements, makes it challenging to isolate the direct effects of collagen. Despite these challenges, the existing evidence suggests that oral collagen supplementation holds high potential as an effective approach for addressing skin aging. However, further long-term studies with larger sample sizes and more diverse populations are necessary to determine the precise mechanisms and optimal dosage, thereby providing more definitive scientific recommendations.

Abstract
Background and Aim: Image brightness heterogeneity is one of the major challenges in computer image processing that can lead to inaccurate results in image segmentation. Despite the existence of numerous segmentation methods, few studies have been conducted on the effect of brightness heterogeneity and the selection of the best color channels in segmentation. In this paper, different color spaces have been used for automatic detection of skin lesions.
Methods: In this study, the LSE (Level Set Evolution) segmentation method along with intensity smoothing has been used for computer recognition of skin lesions. First, the brightness heterogeneity is reduced and a more uniform image is created. Then, the proposed segmentation divides the image domain into distinct regions. This method results in more accurate recognition of skin lesions.
Results: The proposed method has been tested on 200 dermoscopic images from the known PH2 dataset using different color channels. The results show that this method performs better than other methods. Accuracy of 97%, sensitivity of 98%, specificity of 99% and Dice coefficient of 92% have been obtained.
Conclusion: This method has the ability to accurately isolate and diagnose lesions and can help doctors in the treatment process of skin lesions.

Abstract
Impaired wound healing following significant tissue damage such as severe burns, trauma, or surgery can result in scarring and skin fibrosis. Pathological scarring leads to changes in the natural shape of the wound and, in addition to cosmetic problems, may be accompanied by pain and even limit the person's normal movement. The immune response plays a very important role in the wound healing process. Activation of immune cells and factors initiates the inflammatory process, facilitates wound cleansing, and tissue repair and regeneration. However, disruption of the immune system during the wound healing process leads to persistent inflammation and delayed healing, ultimately leading to the development of chronic wounds. The microenvironment of a chronic wound contains a large number of immune cells, including proinflammatory macrophages, and high expression of inflammatory mediators such as TNF-α and IL-1β is observed in it. Among them, macrophages, as innate immune cells, play a key role in promoting the immune response and activating adaptive immunity. These cells are also key factors in the transition from the inflammatory phase to the tissue repair phase. As a result, dysregulation of macrophage function will have consequences such as scarring. Therefore, knowledge of the exact mechanism of the inflammatory process during wound healing, the inflammatory and anti-inflammatory mediators produced, and the effect of macrophages on this process can promise the achievement of new strategies in scarless wound healing. Therefore, this article discusses the mechanism of the immune system during the inflammatory process, and the key role of macrophages in this process, as well as scar formation.

Abstract
Skin infections caused by pathogenic bacteria such as Staphylococcus aureus and Pseudomonas aeruginosa have become a serious challenge in the field of antibacterial therapies, especially in the context of antibiotic resistance. In this regard, the simultaneous use of classical antibiotic combinations with advanced nanostructures is considered a novel and effective approach. Narasin, an ionophore antibiotic of natural origin, has a high potential in inhibiting bacterial growth due to its ability to disrupt cell membrane function and ion transport. On the other hand, silica nanostructures, especially mesoporous silica nanoparticles, play an important role in enhancing antibacterial activity due to their properties such as biocompatibility, drug loading capability, controlled release, and production of reactive oxygen species.
Recent studies have shown that the combination of narasin with silica nanostructures enhances the synergistic antibacterial effects, increases drug stability, and improves penetration into bacterial biofilms. This combination has also been effective in reducing the dosage and systemic toxicity. Despite promising results in laboratory and animal models, challenges such as the assessment of cytotoxicity, precise release control, and the need for extensive clinical studies remain.
In this article, while comprehensively reviewing the properties and functions of narasin and silica nanostructures, the mechanisms of their combined effects on skin pathogenic bacteria are discussed and future prospects in the development of nanobiotechnological therapies are reviewed.

Abstract
Human lip aging is one of the natural signs of the body’s aging process, occurring over time due to factors such as a decrease in collagen and elastin, exposure to sunlight, environmental stress, and genetic changes. As time passes, the lips may lose their appearance, and fine lines or deep wrinkles may form around the lips and the upper lip area. These changes can lead to a reduction in lip volume and the loss of their natural shape. Additionally, dryness and chapping of the lips are other issues commonly observed with lip aging. Skin care, the use of moisturizers, and avoiding prolonged sun exposure can help slow down this process.
