Microglial activation states and their implications for Alzheimer's Disease.

Alzheimer's Disease (AD) is a chronic neurodegenerative disorder characterized by the accumulation of toxic amyloid-beta (Aβ) plaques and neurofibrillary tangles (NFTs) of tau protein in the brain. Microglia, key immune cells of the central nervous system, play an important role in AD development and progression, primarily through their responses to Aβ and NFTs. Initially, microglia can clear Aβ, but in AD, chronic activation overwhelms protective mechanisms, leading to sustained neuroinflammation that enhances plaque toxicity, setting off a damaging cycle that affects neurons, astrocytes, cerebral vasculature, and other microglia.

Serial systemic immune inflammation indices: markers of acute migraine events or indicators of persistent inflammatory status?

Background: Migraine is the most common complex neurological disorder, affecting over a billion people worldwide. Neurogenic inflammation has long been recognized as a key factor in the pathophysiology of migraine though little research has been directed to investigating whether inflammation is greatest in migraine with aura or without, and whether inflammation is a permanent state in migraine or whether is an event related transitory state. Thus, the primary aim of this single-centre, retrospective study was to explore the potential clinical utility of the Serial Systemic Immune-Inflammatory Indices (SSIIi) as a comparative measure of duration and severity of inflammation derived from routine blood cell counts in migraine patients with aura and no-aura both within an acute inpatient setting and as outpatients.

Extract Improves Vascular Dysfunction in Obese Mice Fed a High-Fat Diet.

Background: Obesity is a risk factor for developing cardiovascular diseases (CVDs) by impairing normal vascular function. Natural products are gaining momentum in the clinical setting due to their high efficacy and low toxicity. extract (CFE) has been shown to control appetite and promote weight loss; however, its effect on vascular function remains poorly understood.

Melittin as a therapeutic agent for rheumatoid arthritis: mechanistic insights, advanced delivery systems, and future perspectives.

Rheumatoid arthritis (RA), a condition characterized by joint deterioration through the action of matrix metalloproteinases (MMPs), is prevalent worldwide. Bee venom (BV) has traditionally been used in Chinese medicine for pain, arthritis, rheumatism, skin diseases, etc. BV is enriched with active substances, notably melittin and phospholipase A2 (PLA2), offering significant therapeutic potential.

Gene Polymorphisms in Greek Primary Breast Cancer Patients.

Background: Breast cancer is a heterogeneous disease with distinct clinical subtypes, categorized by hormone receptor status, which exhibits different prognoses and requires personalized treatment approaches. These subtypes included luminal A and luminal B, which have different prognoses. Breast cancer development and progression involve many factors, including interferon-gamma ().

Role of Vitamin B in Healthy Ageing and Disease.

B vitamin complex consist of vitamins B1, B2, B5, B6, B9, B12 and is pivotal for overall health, influencing vital functions such as, energy metabolism, DNA maintenance, and healthy immune system. Inadequate B vitamin levels are associated with various health issues, including neurocognitive problems, immune imbalances, and inflammation. In ageing individuals, deficiencies in B vitamins increase the risk of cardiovascular ailments, stroke, cognitive disorders, neurodegeneration, mental health issues, and methylation-related disorders.

The Role of Calorie Restriction in Modifying the Ageing Process through the Regulation of SIRT1 Expression.

Calorie restriction (CR), as a dietary approach of reducing caloric intake while maintaining nutritional adequacy, has gained significant attention due to its potential role in promoting longevity and enhancing health. Central to the beneficial effects of CR is SIRT1. SIRT1 belongs to a family of NAD+ dependent deacetylases and plays an important role in regulating various cellular processes, including histone deacetylation, oxidative stress response, and mitochondrial biogenesis.

Targeting H3N2 influenza: advancements in treatment and vaccine strategies.

Introduction: The emergence of the H3N2 influenza virus in 1968 marked a significant event as it crossed the species barrier. This shift led to a pandemic, resulting in the deaths of one million people globally and highlighting the virus's severe impact on older individuals due to antigenic drift.

Area Covered: This review comprehensively examines the virological characteristics, evolutionary trends, and global epidemiology of the Influenza A (H3N2) virus.

A review on essential oils: A potential tonic for mental wellbeing in the aging population?

Mental wellbeing is crucial to a good quality of life. With progression in life, mental health can deteriorate, leading to multiple disorders, such as depression, anxiety, stress, and insomnia. Essential oils, from various sources, have a long history of use in aromatherapy.

Early Functional Outcomes and Complications of the First Carpometacarpal Arthroplasty: A Single-Institution Experience.

Rhizarthrosis is accompanied by decreased mobility, poor grip, and progressive pain. Surgical treatment, which involves various techniques, is the only definitive solution sparing the joint. First carpometacarpal (CMC) joint arthroplasty helps reduce the discomfort associated with rhizarthrosis and restores joint function.

Cannabinoids and the male reproductive system: Implications of endocannabinoid signaling pathways.

The escalating use and legalization of cannabis (marijuana) in the United States reflect shifting societal attitudes and growing awareness of its potential therapeutic benefits. Historically viewed as a harmful psychoactive substance, contemporary research has shown the intricate pharmacology of cannabis, with its diverse array of cannabinoids and their interactions with the endocannabinoid system. Among these cannabinoids, Δ9-tetrahydrocannabinol is the primary psychoactive component, characterized by its activation of cannabinoid receptors.

Computational Evidence for Bisartan Arginine Blockers as Next-Generation Pan-Antiviral Therapeutics Targeting SARS-CoV-2, Influenza, and Respiratory Syncytial Viruses.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), influenza, and respiratory syncytial virus (RSV) are significant global health threats. The need for low-cost, easily synthesized oral drugs for rapid deployment during outbreaks is crucial. Broad-spectrum therapeutics, or pan-antivirals, are designed to target multiple viral pathogens simultaneously by focusing on shared molecular features, such as common metal cofactors or conserved residues in viral catalytic domains.

Osteosarcomas of the hand and foot: A sarcoma‑center case series experience.

Hand and foot osteosarcoma represents ~1% of all diagnosed cases of osteosarcoma. The rarity of osteosarcoma of the hand and foot leads to frequent misdiagnosis, delayed diagnosis or incorrect treatments, which can lead to fatal consequences. Typically, salvaging the affected limb is the treatment of choice, and with the use of chemotherapy, 60-65% of patients with osteosarcoma can be treated without amputation.

Assessment of De-Escalation of Empirical Antimicrobial Therapy in Medical Wards with Recognized Prevalence of Multi-Drug-Resistant Pathogens: A Multicenter Prospective Cohort Study in Non-ICU Patients with Microbiologically Documented Infection.

Antimicrobial resistance poses a major threat to human health worldwide and the implementation of antimicrobial stewardship programs (ASPs), including antimicrobial de-escalation (ADE), is a multifaceted tool for minimizing unnecessary or inappropriate antibiotic exposure. This was a prospective observational study of 142 non-Intensive Care Unit (ICU) patients with microbiologically documented infection who were initially administered empirical antimicrobial therapy and admitted to the medical wards of 6 tertiary-care hospitals in Greece from January 2017 to December 2018. Patients were divided into two groups, the ADE and non-ADE group, based on whether ADE was applied or not, respectively.
