Diet-driven microbiome changes and physical activity in cancer patients.

Exploring the role of the gut microbiome in oncology is gaining more attention, mainly due to its ability to shape the immune system in cancer patients. A well-balanced microbial composition forms a symbiotic relationship with the host organism. Mounting evidence supports the potential of modifiable lifestyle factors, such as diet and physical activity, in restoring intestinal dysbiosis related to cancer development and treatment. In this Minireview, we describe the host-microbiome interplay following different dietary patterns, including a high-fat diet, fiber-rich diet, diet rich in rice and

Trichloroethylene: An Invisible Cause of Parkinson's Disease?

The etiologies of Parkinson's disease (PD) remain unclear. Some, such as certain genetic mutations and head trauma, are widely known or easily identified. However, these causes or risk factors do not account for the majority of cases. Other, less visible factors must be at play. Among these is a widely used industrial solvent and common environmental contaminant little recognized for its likely role in PD: trichloroethylene (TCE). TCE is a simple, six-atom molecule that can decaffeinate coffee, degrease metal parts, and dry clean clothes. The colorless chemical was first linked to parkinsonism

Prognostic significance of dipeptidyl peptidase-7 (DPP7) in HPV16-negative head and neck squamous cell carcinoma treated with induction chemoradiotherapy.

BackgroundHead and neck squamous cell carcinoma (HNSCC) significantly impairs critical functions such as speech, swallowing, and breathing, often resulting in disfigurement and a substantial decline in quality of life. Despite advances in treatment, the 5-year survival rate remains approximately 60-65%. This study aimed to assess the impact of induction chemoradiotherapy on organ preservation in HNSCC and to explore the potential role of DPP7 as a diagnostic and prognostic biomarker.MethodsA total of 104 patients with locally advanced, non-metastatic HNSCC were enrolled in the study.

Skin cancer: understanding the journey of transformation from conventional to advanced treatment approaches.

Skin cancer is a global threat to the healthcare system and is estimated to incline tremendously in the next 20 years, if not diagnosed at an early stage. Even though it is curable at an early stage, novel drug identification, clinical success, and drug resistance is another major challenge. To bridge the gap and bring effective treatment, it is important to understand the etiology of skin carcinoma, the mechanism of cell proliferation, factors affecting cell growth, and the mechanism of drug resistance. The current article focusses on understanding the structural diversity of skin cancers, tr

Development of a Serum Metabolome-Based Test for Early-Stage Detection of Multiple Cancers.

BackgroundDetection of cancer at the early stage currently offers the only viable strategy for reducing disease-related morbidity and mortality. Various approaches for multi-cancer early detection are being explored, which largely rely on capturing signals from circulating analytes shed by tumors into the blood. The fact that biomarker concentrations are limiting in the early stages of cancer, however, compromises the accuracy of these tests. We, therefore, adopted an alternate approach that involved interrogation of the serum metabolome with machine learning-based data analytics. Here, we mon

Impact of Vitamin D Supplementation on Multiple Sclerosis.

Multiple sclerosis (MS) is an autoimmune disease affecting a large number of people every year. The exact causal factor for this disease is unclear, but it commonly affects middle-aged women, with known triggers like stress, childbirth, infections, poor diet, lack of sleep, etc. Many epidemiological studies have indicated that various genetic abnormalities are also critical drivers of the onset of MS. The major risk factors of MS identified include hypovitaminosis D while environmental protective factors include allele HLA DRB1 1501, obesity, Epstein-Barr virus infection, sexual hormones, and

Адаптация эукариот-подобных PRS к прокариот-подобным tRNAPro.

Синтеты Проли-ТРНА (ПРОРС) уникальны среди аминоачил-тРНК (ААРС) two различные структурные архитектуры различных организмов: прокариота-подобные (П-тип) и эукариоте/археон-подобные (Е-тип). Интересно, что Бакиллус Тюрингьенси гавань обоих типов, сосуществует P-тип (BtProRS1) и E-тип PRS (BtProRS2). Несмотря на свои различия, оба фермента формально выражаются и функционируют в vivo. По аналогии с BtProRS1, BtPRS2 выборочно заряжает TRNAPro типа P и демонстрирует более высокий допуск к галоугинону, чем каноническая PRS. Однако эти two Изозимы признают основные идентификационные элементы типа P t

The predictors of spiritual dryness among Iranian cancer patients during the COVID-19 pandemic.

BackgroundSpiritual struggles affect the wellbeing of religious people. Among them are strugglers with God which is perceived as non-responsive and distant. These perceptions were so far analyzed predominantly in Western societies with a Christian background, but not in Muslims from Iran. The aim of this study was to determine the predictors of spiritual dryness among cancer patients in Iran during the COVID-19 pandemic.MethodsCross-sectional study with standardized questionnaires (i.e., Spiritual Dryness Scale, WHO-5, BMLSS-10, Awe/Gratitude Scale) among 490 cancer patients (mean age 49.50 ±

Pharmacogenomics and Big Data in medical oncology: developments and challenges.

Medical oncology, through conventional chemotherapy as well as targeted drugs, remains an important component of cancer patient management, particularly for systemic disease. Despite advances in all areas of medical oncology, certain challenges persist in the form of drug resistance and severe normal tissue toxicity. These unwanted effects can be counteracted through a patient-tailored treatment approach, which in chemotherapy is translated as pharmacogenomics. This research field investigates the way genetic makeup influences a patient's response to various drugs with the aim to minimize tria

Influence of the Mediterranean Diet on Healthy Aging.

The life expectancy of the global population has increased. Aging is a natural physiological process that poses major challenges in an increasingly long-lived and frail population. Several molecular mechanisms are involved in aging. Likewise, the gut microbiota, which is influenced by environmental factors such as diet, plays a crucial role in the modulation of these mechanisms. The Mediterranean diet, as well as the components present in it, offer some proof of this. Achieving healthy aging should be focused on the promotion of healthy lifestyle habits that reduce the development of pathologi
