Article Synopsis
  • The study explores how the Vision Transformer (ViT) can be used for analyzing medical images, specifically for diagnosing osteoporosis from X-ray images.
  • Researchers compared the performance of ViT to traditional convolutional neural networks (CNNs) to see which method was more effective in classification tasks.
  • Results indicated that ViT outperforms CNNs, especially when there is ample training data available, leading to better solutions for medical image analysis.

Chemotherapy and radiotherapy are widely used in clinical practice across the globe as cancer treatments. Intrinsic or acquired chemoresistance poses a significant problem for medical practitioners and researchers, causing tumor recurrence and metastasis. The most dangerous kind of malignant brain tumor is called glioblastoma multiforme (GBM) that often recurs following surgery.

Article Synopsis
  • Highly pathogenic avian influenza viruses like H5N1 pose a potential pandemic threat, but their rapid mutation makes vaccine development difficult.
  • Researchers utilized an in silico method to design a multi-epitope vaccine targeting the H5N1 virus, incorporating various immune system components and adjuvants to enhance the immune response.
  • The study confirmed the vaccine's antigenicity, non-toxicity, and solubility, and showed promising results in molecular interactions with immune receptors TLR7 and TLR8, suggesting it could effectively stimulate T and B cell responses.

Article Synopsis
  • - Zymosan nanoparticles, derived from yeast, have been developed for drug delivery, particularly with doxorubicin (DOX), and their properties were analyzed using various sophisticated techniques.
  • - The release of DOX from these nanoparticles depends on pH, and their impact on cancer cells was assessed, showing these carriers enhance the effectiveness of DOX against C26 cells by affecting specific gene expressions related to cancer growth and apoptosis.
  • - The study indicates that zymosan nanoparticles not only improve targeted drug delivery but also promote cell death in cancer cells by modifying key signaling pathways, leading to a synergistic anti-cancer effect.

Autoimmune diseases are a diverse set of conditions defined by organ damage due to abnormal innate and acquired immune system responses. The pathophysiology of autoimmune disorders is exceedingly intricate and has yet to be fully understood. The study of long non-coding RNAs (lncRNAs), non-protein-coding RNAs with at least 200 nucleotides in length, has gained significant attention due to the completion of the human genome project and the advancement of high-throughput genomic approaches.

Article Synopsis
  • * Traditional treatments may not work for these chronic wounds because diabetes disrupts the body’s natural healing processes.
  • * Mesenchymal stem cells (MSCs) show promise in enhancing wound healing by supporting the body’s immune response, differentiating into necessary cell types, and promoting new blood vessel formation.

Gastrointestinal (GI) cancers are among the main reasons for cancer death globally. The deadliest types of GI cancer include colon, stomach, and liver cancers. Multiple lines of evidence have shown that angiogenesis has a key role in the growth and metastasis of all GI tumors.

Gynecological cancer affects the female reproductive system, including ovarian, uterine, endometrial, cervical, vulvar, and vaginal tumors. Non-coding RNAs (ncRNAs), and in particular microRNAs, function as regulatory molecules, which can control gene expression in a post-transcriptional manner. Normal physiological processes like cellular proliferation, differentiation, and apoptosis, and pathological processes such as oncogenesis and metastasis are regulated by microRNAs.

Gynecologic cancers involve the female genital organs, such as the vulva, vagina, cervix, endometrium, ovaries, and fallopian tubes. The occurrence and frequency of gynecologic cancer depends on personal lifestyle, history of exposure to viruses or carcinogens, genetics, body shape, and geographical habitat. For a long time, research into the molecular biology of cancer was broadly restricted to protein-coding genes.

Bladder cancer, a life-threatening serious disease, is responsible for thousands of cancer-associated deaths worldwide. Similar to other malignancies, standard treatments of bladder cancer, such as Chemoradiotherapy, are not efficient enough in the affected patients. It means that, according to recent reports in the case of life quality as well as the survival time of bladder cancer patients, there is a critical requirement for exploring effective treatments.

Glioma is known as one of the most common primary intracranial tumors accounting for four-fifths of malignant brain tumors. There are several biological pathways that play a synergistic, pathophysiological role in glioma, including apoptosis, autophagy, oxidative stress, and cell cycle arrest. According to previous rese arches, the drugs used in the treatment of glioma have been associated with significant limitations.

Osteosarcoma (OS) is a kind of primary bone cancer that is considered as the leading cause of children death. Surgery and chemotherapy are considered as common treatment approaches for OS; the rate of survival for patients is almost 60-70%. Besides the used therapeutic approaches, it seems that there is a crucial need to launch new treatments for OS.
