Medical Ozone Treatment Attenuates Male Reproductive Toxicity Induced by Bleomycin, Etoposide, and Cisplatin Regimen in an Experimental Animal Model.

The chemotherapeutic combination of bleomycin, etoposide, and cisplatin (BEP) is well-documented to exert gonadotoxic effects, ultimately leading to impaired fertility. This experimental rat study investigated the potential protective role of repeated medical ozone therapy in mitigating the deleterious effects of BEP treatment in male rats. Thirty-two adult male Sprague Dawley rats were randomly assigned to four groups: (i) a healthy control group, (ii) a group receiving injections of the BEP regimen over nine weeks, (iii) a group receiving the same BEP regimen plus medical ozone (1 mg/kg IP)

Anti-Tumor Effects of Low Dose Zoledronate on Lung Cancer-Induced Spine Metastasis.

Zoledronate (Zol) is an anti-resorptive/tumoral agent used for the treatment of many cancers including spinal bone metastasis. High systemic administration of a single dose is now the standard clinical care, yet it has been associated with several side effects. Here, we aimed to evaluate the effects of lower doses Zol on lung cancer and lung cancer-induced bone metastasis cells over a longer time period. Human lung cancer (HCC827) and three bone metastases secondary to lung cancer (BML1, BML3 and BML4) cells were treated with Zol at 1, 3 and 10 µM for 7 days and then assessed for cell prolifer

Biosensors, Artificial Intelligence Biosensors, False Results and Novel Future Perspectives.

Medical biosensors have set the basis of medical diagnostics, and Artificial Intelligence (AI) has boosted diagnostics to a great extent. However, false results are evident in every method, so it is crucial to identify the reasons behind a possible false result in order to control its occurrence. This is the first critical state-of-the-art review article to discuss all the commonly used biosensor types and the reasons that can give rise to potential false results. Furthermore, AI is discussed in parallel with biosensors and their misdiagnoses, and again some reasons for possible false results

Recent Advances in Therapeutics for the Treatment of Alzheimer's Disease.

The most prevalent chronic neurodegenerative illness in the world is Alzheimer's disease (AD). It results in mental symptoms including behavioral abnormalities and cognitive impairment, which have a substantial financial and psychological impact on the relatives of the patients. The review discusses various pathophysiological mechanisms contributing to AD, including amyloid beta, tau protein, inflammation, and other factors, while emphasizing the need for effective disease-modifying therapeutics that alter disease progression rather than merely alleviating symptoms. This review mainly covers m

Cancer health disparities in racial/ethnic minorities in the United States.

There are well-established disparities in cancer incidence and outcomes by race/ethnicity that result from the interplay between structural, socioeconomic, socio-environmental, behavioural and biological factors. However, large research studies designed to investigate factors contributing to cancer aetiology and progression have mainly focused on populations of European origin. The limitations in clinicopathological and genetic data, as well as the reduced availability of biospecimens from diverse populations, contribute to the knowledge gap and have the potential to widen cancer health dispar

The cGAS-STING pathway in senescence and aging-related diseases: mechanisms and therapeutic opportunities.

The cGAS-STING pathway acts as a critical molecular hub connecting genomic instability with cellular senescence. Functioning as a key regulator of the innate immune system, this pathway detects aberrant cytoplasmic DNA to activate downstream inflammatory responses, thereby playing a pivotal role in aging-related diseases. This review systematically explores the core mechanisms by which the cGAS-STING pathway regulates cellular senescence, emphasizing its role in triggering senescence through the recognition of DNA damage signals (e.g., oxidative stress, telomere dysfunction) and promoting para

Regional, demographic and temporal trends in anemia and malignant cancer-related mortality in U.S. older adults: a nationwide CDC WONDER analysis (1999-2020).

PurposeAnemia and malignancy concurrently contribute to reduced quality of life, treatment intolerance, and increased morbidity and mortality, disproportionately affecting older adults, socioeconomically disadvantaged groups, and minority populations. Despite its clinical importance, national patterns and population-level disparities in the mortality burden associated with this comorbidity remain poorly characterized. This study aims to examine mortality trends associated with concurrent anemia and malignancy in the United States using CDC WONDER (Centers for Disease Control and Prevention Wid

Plasma Heat Shock Protein 90 Alpha: A Valuable Predictor of Early Chemotherapy Effectiveness in Advanced Non-Small-Cell Lung Cancer.

BACKGROUND Heat shock protein-90 alpha (HSP90a) is more abundant in non-small-cell lung cancer (NSCLC) patients than in control individuals. However, whether it can reflect chemotherapy efficacy remains unknown. This study aimed to investigate the association of HSP90a with chemotherapy in advanced NSCLC. MATERIAL AND METHODS We retrospectively evaluated data from patients admitted to the Department of Respiratory Medicine, Shaoxing People's Hospital, from September 2016 to September 2018 with stage IIIB or IV NSCLC and administered 4 cycles of third-generation platinum-based combination chemo

Molecular mechanisms underlying methotrexate-induced intestinal injury and protective strategies.

Methotrexate (MTX) is a folic acid reductase inhibitor that manages various malignancies as well as immune-mediated inflammatory chronic diseases. Despite being frequently prescribed, MTX's severe multiple toxicities can occasionally limit its therapeutic potential. Intestinal toxicity is a severe adverse effect associated with the administration of MTX, and patients are significantly burdened by MTX-provoked intestinal mucositis. However, the mechanism of such intestinal toxicity is not entirely understood, mechanistic studies demonstrated oxidative stress and inflammatory reactions as key fa

Male Lower Urinary Tract Dysfunction: An Underrepresented Endpoint in Toxicology Research.

Lower urinary tract dysfunction (LUTD) is nearly ubiquitous in men of advancing age and exerts substantial physical, mental, social, and financial costs to society. While a large body of research is focused on the molecular, genetic, and epigenetic underpinnings of the disease, little research has been dedicated to the influence of environmental chemicals on disease initiation, progression, or severity. Despite a few recent studies indicating a potential developmental origin of male LUTD linked to chemical exposures in the womb, it remains a grossly understudied endpoint in toxicology research

Pharmacomicrobiomics in Anticancer Therapies: Why the Gut Microbiota Should Be Pointed Out.

Anticancer treatments have shown a variable therapeutic outcome that may be partly attributable to the activity of the gut microbiota on the pathology and/or therapies. In recent years, microbiota-drug interactions have been extensively investigated, but most of the underlying molecular mechanisms still remain unclear. In this review, we discuss the relationship between the gut microbiota and some of the most commonly used drugs in oncological diseases. Different strategies for manipulating the gut microbiota layout (i.e., prebiotics, probiotics, antibiotics, and fecal microbiota transplantati

Treating Infected Non-Healing Venous Leg Ulcers with Medical-Grade Honey: A Prospective Case Series.

Venous leg ulcers (VLUs) are hard-to-heal wounds and are prone to microbial colonization. Innovative and improved therapies are thus required to resolve local infection and enhance the wound healing process. The objective of this study was to evaluate the effectiveness of medical-grade honey (MGH) for the treatment of clinically infected and non-healing VLUs. This prospective case series included nine patients with an average age of 83.4 years (range: 75-91 years) with a total of eleven VLUs, previously ineffectively treated with various products. Major risk factors for the appearance of VLUs

Construction for the predictive model of quality of life in patients after robot-assisted radical prostatectomy: a cohort study.

Background: Urinary incontinence (UI) and erectile dysfunction (ED) often arise as frequent postoperative complications following robotic-assisted radical prostatectomy (RARP) for prostate cancer (PCa). These issues can significantly diminish patients' quality of life (QoL). The assessment of QoL is even more important because treatment decisions may be influenced by the expected QoL. Few studies have integrated the clinical profiles of patients with magnetic resonance imaging (MRI) metrics to assess postoperative UI and ED. Methods: PCa patients treated with RARP between January 2018 and Sept

Cancer-Induced Cardiac Dysfunction: Mechanisms, Diagnostics, and Emerging Therapeutics in the Era of Onco-Cardiology.

Cancer-induced cardiac dysfunction has become a major clinical challenge as advances in cancer therapies continue to extend patient survival. Once regarded as a secondary concern, cardiotoxicity is now recognized as a leading contributor to morbidity and mortality among cancer patients and survivors. Its pathophysiology is multifactorial, involving systemic inflammation (e.g., TNF-α, IL-6), oxidative stress driven by reactive oxygen species (ROS), neurohormonal imbalances (e.g., angiotensin II, endothelin-1), and metabolic disturbances. These mechanisms collectively promote cardiomyocyte apopt
