Abstract
Enzymes have been used experimentally in the preparation of fermented, food, and medicinal products since mankind started a regular life in the form of early civilizations, without any information about their nature being available. It has been more than a century since scientists have obtained information about the enzymatic reactions and the enzyme structure, and a newer and more practical attitude towards them is obtained day by day. Today, these proteins play roles as biomarkers in the diagnosis, monitoring and treatment of diseases. Enzymes roles as receptor for some hormones and their qualitative and quantitative changes interfering in the onset of some diseases such as diabetes have been known. In addition, they are used as accurate and specific tools in the assay of some biochemical analytes, phenotypic identification of bacteria and biosensor design. The basis of the mechanism of some drugs is enzyme inhibition. Meanwhile, some enzymes are directly used as drugs. The enzymes are applied in some immunoassay techniques, genetics and proteomics laboratory methods. In modern biotechnology, enzymes are used to produce plenty of products. This review article aimed to take a new, updated and comprehensive approach to several roles that enzymes play in various fields from diagnosis, monitoring and treatment of diseases to their application in medical, genetics and proteomics laboratory methods.

Abstract
Endometriosis is a long-term health condition that is known as a significant factor in women's infertility issues nowadays. Since many factors contribute to the development of this disease and because diagnosis is difficult and typically happens late in the progression of the disease, early detection is especially crucial. Extracellular micro vesicles called exosomes have diverse biological molecules and can alter the behavior of recipient cells, influencing angiogenesis, fibrosis, and inflammation. Exosomes are significant in cell communication and could act as new biomarkers for early detection of endometriosis. Hence, exploring and comprehending the impact of exosomes on the development of endometriosis can create opportunities for studying potential diagnostic biomarkers and targeted therapeutic interventions to prevent the advancement of the condition. This article delves into new approaches to diagnose and treat endometrial disorders by highlighting the various functions of exosomes in endometriosis.

Abstract
Leishmaniasis is a parasitic infectious disease that accounts for approximately one million new cases annually. The treatment of this disease is complex and costly, particularly in developing countries. Numerous studies have been conducted on various vaccines utilizing live attenuated parasites, killed parasites, subunit antigens, recombinant vaccines, and DNA technology. However, an effective and widely applicable preventive vaccine for leishmaniasis has not yet been developed. Present study aimed to examine the progress in the development of leishmaniasis vaccines.
Articles for this study were selected from the PubMed, Web of Science and Scopus databases using relevant keywords, focusing on subject matter, scientific quality, and publication date, with an emphasis on more recent publications.
Research on the development of leishmaniasis vaccines indicates that several candidates, such as Leishmune, CaniLeish, and Leish-Tec, which are at various stages of clinical trials, may serve as suitable options for controlling and preventing leishmaniasis in dogs. The LeishChim vaccine, designed using immunoinformatics and molecular docking techniques, has shown promising efficacy results in mouse studies. Additionally, the mutant gene-centered LmCen-/- vaccine has completed Phase 1 clinical trials in humans.
Given the importance of developing a leishmaniasis vaccine, research in this area continues. Utilizing immunoinformatics and biological modeling studies can aid in the faster identification of effective vaccine candidates.

Abstract
Alzheimer's disease is a progressive, incessant and neurodegenerative disorder that affects large areas of the cerebral cortex and hippocampus. Abnormalities first involve the frontal and temporal lobes in the brain tissue and then slowly reach other areas of the neocortex. It seems that Alzheimer's patients who participated in sports activities had an increase in blood flow, hippocampal volume and improved neurogenesis. In this study, we provide an overview of the positive effects of exercise on the biomarkers of this challenging disease. In this study, PubMed, Google Scholar, and SID.IR databases were searched with the keywords "Alzheimer, Resistance Training, Endurance Training, Biomarker" between the years 2000 and 2024. The results of the studies indicate that exercise can be a non-pharmacological strategy to prevent or delay the decline of the cognitive power of the brain. Exercise also plays an effective role in changes in plasma biomarkers associated with Alzheimer's and cognitive impairment associated with the disease. Among the changes created following sports activity, we can mention the increase in the expression of neurotrophic factors in the brain, inhibition of oxidative stress, and angiogenesis, which leads to an increase in blood supply to the hippocampus tissue.

Abstract
Immunotherapy has emerged as a promising and effective approach in cancer treatment by stimulating the body’s immune system to target and eliminate malignant cells. Despite its significant therapeutic potential, several challenges remain, including accurate patient selection, identification of appropriate therapeutic targets, and the minimization of adverse effects.
Artificial intelligence (AI) plays a critical role in addressing these challenges by analyzing complex genomic, proteomic, and clinical datasets. Machine learning and deep learning algorithms can accurately identify patients likely to respond to immunotherapy, enabling the development of personalized treatment plans while avoiding unnecessary interventions in low-response individuals.
A key application of AI is predicting the efficacy of immune checkpoint inhibitors such as PD-1 and CTLA-4. By integrating medical imaging and genomic data, AI models can forecast treatment outcomes, enhance diagnostic precision, and reduce healthcare costs. Furthermore, AI is increasingly used in drug development, where it simulates novel molecular structures and predicts their therapeutic efficacy, thereby accelerating drug discovery and lowering development expenses. AI also contributes to identifying and managing side effects, improving the safety profile of immunotherapy.
Nevertheless, the implementation of AI in oncology is not without limitations. These include the need for high-quality, annotated datasets, algorithmic interpretability, and ethical concerns such as data privacy, algorithm transparency, and psychological impacts of extensive genetic testing, excessive diagnostic testing, potential treatment discrimination, and unclear legal responsibilities.
This article concludes that with robust data infrastructure and the advancement of interpretable AI models, the full potential of AI in cancer immunotherapy can be realized. This synergy promises a major leap toward precision medicine and a brighter future in cancer care.

Abstract
Colorectal cancer (CRC) remains one of the most prevalent gastrointestinal malignancies, posing significant challenges in diagnosis and treatment. Recent research has highlighted exosomes and their non-coding RNA (ncRNA) cargo as key players in tumor progression and novel diagnostic tools. Exosomes are extracellular vesicles (50-150 nm) secreted by normal and cancer cells that mediate intercellular communication. This comprehensive review examines the role of exosomal miRNAs, lncRNAs, and circRNAs in critical oncogenic processes including angiogenesis, metastasis, drug resistance, and immune modulation. Emerging evidence demonstrates that specific exosomal ncRNA contents may serve as sensitive and specific biomarkers for early detection, prognosis prediction, and monitoring of treatment response. However, challenges persist regarding standardization of exosome isolation methods and the need for expanded clinical validation. Advances in exosome research technologies hold promise for translating these findings into personalized medicine approaches. This review synthesizes current knowledge on the pathophysiological significance of exosomal ncRNAs in CRC and their clinical potential as diagnostic and therapeutic targets, while addressing existing limitations and future research directions in this rapidly evolving field.
