RESUMEN
This study delves into Usher syndrome type 2 (USH2), an uncommon genetic disorder characterized by sensorineural hearing loss (HL) and retinitis pigmentosa (RP), often associated with the USH2A gene. Focusing on an Iranian family exhibiting USH2 symptoms, exome-sequencing was employed for a comprehensive genome analysis in a 30-yearold patient. The investigation unveiled a novel variation (NM_206933.4: c.9389G>A; p.Trp3130*) within exon 48 of the USH2A gene, a previously unreported variant emphasizing the genetic diversity in USH2. Sanger sequencing was then utilized to assess variation segregation within the family, offering insights into the inheritance pattern. This discovery not only advances our understanding of the genetic basis of USH2 but also holds significant implications for genetic counseling, early management, and informed decision-making regarding prenatal options. By adopting an integrated approach, this study aims to empower affected families, facilitating a nuanced understanding of the disorder's complexities and ultimately improving patient outcomes and family well-being through informed decisionmaking and proactive management strategies.

RESUMEN
BACKGROUND: Obesity, a global challenge, is a complex disorder linked to various diseases. Different kinds of treatments are currently used to treat or control this pandemic. Despite their positive effects on controlling obesity, they still have limitations and side effects including digestive problems, difficulties of daily infusion of some drugs, surgical complications, and weight regain. All these issues cause these conventional methods not to have desirable efficacy. In this regard, brown adipose tissue (BAT) transplantation as a new investigational treatment is proposed, which has beneficial effects with no documented side effect in studies up to now. METHODS: This systematic review protocol was registered in the International Prospective Register of Systematic Reviews (Registration Number: CRD42018110045). The systematical search was conducted on Web of Science, Scopus, PubMed, Embase, and ProQuest databases. The quality assessments in the included studies and data gathering were conducted independently by two authors. The main variables were anthropometric indices including body weight, levels of leptin, IGF-1, glucagon, adiponectin, fasting blood glucose, and UCP-1. RESULTS: Following the search in mentioned databases, ten articles were entered into this systematic review. In most studies, weight gain and white adipocyte size were reduced in the BAT transplant group. It seems that the transplantation leads to the regeneration of healthy adipose tissue by activating the endogenous BAT. CONCLUSIONS: Since BAT transplantation is one of the possible future treatments of obesity, many studies are conducted to evaluate the outcomes and related procedures precisely, so it can finally step into clinical application.

Recently, gene therapy as one of the most promising treatments can apply genes for incurable diseases treatment. In this context, vectors as gene delivery systems play a pivotal role in gene therapy procedure. Hereupon, viral vectors have been increasingly introduced as a hyper-efficient tools for gene therapy. Adenoviral vectors as one of the most common groups which are used in gene therapy have a high ability for humans. Indeed, they are not integrated into host genome. In other words, they can be adapted for direct transduction of recombinant proteins into targeted cells. Moreover, they have large packaging capacity and high levels of efficiency and expression. In accordance with translational pathways from the basic to the clinic, recombinant adenoviral vectors packaging must be managed under good manufacturing practice (GMP) principles before applying in clinical trials. Therein, in this chapter standard methods for manufacturing of GMP-compliant Adenoviral vectors for gene therapy have been introduced.

Breast cancer is a heterogeneous disease, which is the consequence of several genetic and environmental factors. Also, it is one of the most common causes of cancer death and second leading cancer among women all around the world. Therefore, it is necessary to develop novel therapeutic approaches useful for the successful treatment of breast cancer. As conventional treatments had limited success, alternative approaches for the treatment of breast cancer have been applied in recent years. Hence, the molecular basis of breast cancer has provided the opportunity of using genetic materials for therapeutic uses. In this regard, gene therapy as one of the potentially efficient and beneficial treatments among various techniques became a popular treatment for different cancers, especially breast cancer. Accordingly, there are plenty of targets available for gene therapy of breast cancer. Gene therapy strategies have the potential to correct molecular defects that contributed to the cancer progression. These techniques should selectively target tumor cells without affecting normal cells. Moreover, data of clinical trials in gene therapy for breast cancer indicated that this approach has little toxicity compared to other therapeutic approaches. In this study, different aspects of breast neoplasm, gene therapy techniques, challenges, and recent developments will be mentioned.

Although stem cells have the most therapeutic potential, the advantages of regenerative medicine may be best provided using extracellular vesicles which also known in the past as "cellular dust." These microparticles are substances released by cells and play a pivotal role in pathophysiology of tumor progression and metastasis, thrombosis, and inflammation. Extracellular vesicles including exosomes and cell-derived microparticles supporting many physiological and disease processes which are relevant to immunology, hemostasis, thrombosis, neurobiology, cell signaling, angiogenesis, and cancer. While they have not any value for many years, this cellular dust has been studied and shows therapeutic properties similar to their mother cells (stem cells) but without their disadvantages. These vesicles do not divide, limiting the risk of cancer, and do not differentiate either. Therefore, they prevent tumor progression and development of poor function. Furthermore, it appears that they can be produced by a single donor for several patients, and have already confirmed their therapeutic potential in animals in repairing heart, liver and kidney lesions. The present study was aimed to introduce cellular dust as a new horizon for regenerative cancer medicine and also new hope for potential therapeutic applications of cancer and associated diseases.

Gene therapy as a novel study in molecular medicine will have a significant impact on human health in the near future. In recent years, the scope of gene therapy has been developed and is now beginning to revolutionize therapeutic approaches. Accordingly, many types of diseases are now being studied and treated in clinical trials through various gene delivery vectors. The emergence of recombinant DNA technology which provides the possibility of fetal genetic screening and genetic counseling is a good case in point. Therefore, gene therapy advances are being applied to correct inherited genetic disorders such as hemophilia, cystic fibrosis, and familial hypercholesterolemia as well as acquired diseases like cancer, AIDS, Alzheimer's disease, Parkinson's disease, and infectious diseases like HIV. As a result, gene therapy approaches have the ability to help the vast majority of newborns with different diseases. Since these ongoing treatments and clinical trials are being developed, many more barriers and challenges have been created. In order to continue this positive growth, these challenges need to be recognized and addressed. Accordingly, safety, efficiency and also risks and benefits of gene therapy trials for each disease should be considered. As a result, sustained manufacturing of the therapeutic gene product without any harmful side effects is the least requirement for gene therapy. Herein, different aspects of gene therapy, an overview of the progress, and also the prospects for the future have been discussed for the successful practice of gene therapy.

PURPOSE: The healing process is impaired in diabetic wounds like the other types of chronic wounds. Cytokines, and growth factors are valuable candidates for determination of wound vitality or duration. The aim of this study is to introduce a beneficial method to stop the inflammatory phase and infection in the wound healing process for accelerating the treatment of diabetic foot ulcers. METHODS: As a randomized controlled trial, 44 patients with diabetic foot ulcers were selected and randomized. Twenty-two patients received standard care and rest of them received SC (standard care) + CAP (cold atmospheric plasma), n = 22). Clinical examination was performed to assess the status of peripheral nerves and arteries for all patients. Cold plasma jet was used as a source of helium gas plasma generator. Plasma was irradiated on the wound 5 min, 3 times a week for 3 consecutive weeks. RESULTS: Applying a plasma jet was effective in wound healing. The level of inflammatory cytokines was changed. Moreover, after applying plasma the mean expression of these variables was significantly decreased (P = 0.001). Following the plasma treatment, the level of cytokines such as IL-1 (39.44 ± 7.67), IL-8 (368.30 ± 82.43), INF-γ (17.03 ± 2.62), TNFα (22.75 ± 4.02) has decreased, inflammatory factors have ameliorated over three weeks, and accelerate wound healing. After CAP exposure, the mean of the mean fraction of bacterial load counts was significantly decreased. CONCLUSION: The effect of plasma irradiation on infectious diabetic foot ulcer was decreased bacterial load then accelerated wound healing by effecting on inflammatory phase in diabetic foot ulcers.
