Alzheimer's disease (AD) is a leading cause of cognitive decline in the aging population, presenting a critical need for early diagnosis and effective prognostic tools. Epigenetic modifications, including DNA methylation, histone modifications, and non-coding RNAs, have emerged as promising biomarkers for AD due to their roles in regulating gene expression and potential for reversibility. This review examines the current landscape of epigenetic biomarkers in AD, emphasizing their diagnostic and prognostic relevance.

Periodontitis Continuum: Antecedents, Triggers, Mediators, and Treatment Strategies.

Periodontitis (PD) is a chronic inflammatory disease of the periodontium characterized by the formation of gingival pockets and gingival recession. The local inflammatory environment can lead to the destruction of the extracellular matrix and subsequent bone loss. The pathophysiology of PD involves interactions between genetic predisposition, lifestyle, environmental factors, the oral microbiota condition, systemic health disorders, innate and adaptive immune responses, and various host defenses.

This systematic review will provide insight into host genetic and epigenetic factors that interfere with COVID-19 expression in light of available evidence.

The Possible Roles of β-alanine and L-carnosine in Anti-aging.

alanine (BA), being a non-proteinogenic amino acid, is an important constituent of L-carnosine (LC), which is necessary for maintaining the muscle buffering capacity and preventing a loss of muscle mass associated with aging effects. BA is also very important for normal human metabolism due to the formation of a part of pantothenate, which is incorporated into coenzyme A. BA is synthesized in the liver, and its combination with histidine results in the formation of LC, which accumulates in the muscles and brain tissues and has a well-defined physiological role as a good buffer for the pH range of muscles that caused its rapidly increased popularity as ergogenic support to sports performance.

An Update on Glutathione's Biosynthesis, Metabolism, Functions, and Medicinal Purposes.

Glutathione (GSH) has been the focus of increased scientific interest in the last decades. It plays a crucial role in all major physiological processes by supplying antioxidant defenses through participating in cellular redox reactions in the human body and other living organisms. GSH also participates in detoxifying xenobiotics, protecting protein thiols from crosslinking and oxidation, regulating the cell cycle, storing cysteine, etc.

Potential Drugs in COVID-19 Management.

The SARS-CoV-2 virus first emerged in China in December 2019 and quickly spread worldwide. Despite the absence of a vaccination or authorized drug specifically developed to combat this infection, certain medications recommended for other diseases have shown potential effectiveness in treating COVID-19, although without definitive confirmation. This review aims to evaluate the existing literature on the efficacy of these medications against COVID-19.

Natural Compounds Used for Treating Hair Loss.

Hair loss or alopecia is a common dermatological condition affecting up to 2% of the world population. It is often caused by hereditary factors, such as male or female pattern baldness, but it can also result from various environmental factors, an unbalanced diet, or chronic illness. While hair loss is not life-threatening, it can cause significant anxiety, depression, and other psychological problems, ultimately impacting an individual's quality of life.

Pharmacological Treatments and Natural Biocompounds in Weight Management.

The obesity pandemic is one of society's most urgent public health concerns. One-third of the global adult population may fall under obese or overweight by 2025, suggesting a rising demand for medical care and an exorbitant cost of healthcare expenditure in the coming years. Generally, the treatment strategy for obese patients is largely patient-centric and needs dietary, behavioral, pharmacological, and sometimes even surgical interventions.

The use of natural bioactive constituents from various food sources for anticancer purposes has become increasingly popular worldwide. Broccoli ( var. ) is on the top of the consumed vegetables by the masses.

Natural Ingredients to Improve Immunity.

The immune system protects the body from infectious agents such as bacteria, viruses, or fungi. Once encountered with pathogens or antigens, the innate and adaptive arms of the immune system trigger a strong immune response to eliminate them from the system and protect the body. Thus, well-balanced immunity is pivotal for maintaining human health, as an insufficient level of immune defense leads to infections and tumors.

Traditional Chinese Medicine as the Preventive and Therapeutic Remedy for COVID-19.

The coronavirus disease 2019 (COVID-19) pandemic still has tremendous impacts on the global socio-economy and quality of living. The traditional Chinese Medicines (TCM) approach showed encouraging results during previous outbreaks of Severe Acute Respiratory Syndrome-related Coronavirus (SARS-CoV) and the Middle East Respiratory Syndrome Coronavirus (MERS-CoV). With limited treatment availability, TCM herbs and formulations could be useful to reduce COVID-19 symptoms and potential sources for discovering novel therapeutic targets.
