Infrared Radiation in Management of Musculoskeletal Conditions
Infrared radiation (IR), also known as infrared light, consists of electromagnetic radiation with wavelengths but shorter than microwave radiation and longer than visible light (750 nm to 1 mm). IR derives from thermal energy; hence, material bodies emitting heat can produce it. Higher temperatures lead to the production of higher amounts of IR of higher frequency and shorter wavelength. IR consists of a promising complementary treatment for a wide range of musculoskeletal conditions, including knee osteoarthritis, fibromyalgia, chronic low back pain, chronic myofascial syndrome, sacroiliitis, and Gulf War Illness. Infrared therapy can be delivered with light-emitting devices (photobiomodulation), wires, ceramic materials, and IR saunas. In a number of studies, infrared therapy has also been associated with clinical and perceptual improvement in chronic-pain-related psychosomatic symptoms such as fatigue and insomnia.

Helicobacter pylori Diagnosis
Helicobacter pylori infection still remains one of the most prevalent infections worldwide, especially in low-resource countries, and the major risk factor for peptic ulcer and gastric cancer. The "test-and-treat" strategy is recommended by several guidelines and consensus. The choice of testing method is based on patient age, presence of alarm signs and/or symptoms, use of non-steroidal anti-inflammatory drugs, as well as local availability, test reliability and cost. Culture is the gold standard to detect H. pylori and, possibly, to perform susceptibility testing, however, it requires upper endoscopy and dedicate labs. Recent advances in molecular biology provide new strategies in detecting the infection and antimicrobial resistance without invasive tests.

p53 Mutations in Cancers
The members of the p53 family comprise p53, p63, and p73, and full-length isoforms of the p53 family have a tumor suppressor function. However, p53, but not p63 or p73, has a high mutation rate in cancers causing it to lose its tumor suppressor function.

DHA and AA: Neuroprotective Nutrient
The role of docosahexaenoic acid (DHA) and arachidonic acid (AA) in neurogenesis and brain development throughout the life cycle is fundamental. DHA and AA are long-chain polyunsaturated fatty acids (LCPUFA) vital for many human physiological processes, such as signaling pathways, gene expression, structure and function of membranes, among others. DHA and AA are deposited into the lipids of cell membranes that form the gray matter representing approximately 25% of the total content of brain fatty acids. Both fatty acids have effects on neuronal growth and differentiation through the modulation of the physical properties of neuronal membranes, signal transduction associated with G proteins, and gene expression. DHA and AA have a relevant role in neuroprotection against neurodegenerative pathologies such as Alzheimer’s disease and Parkinson’s disease, which are associated with characteristic pathological expressions as mitochondrial dysfunction, neuroinflammation, and oxidative stress.

Parenteral Nutrition and Sepsis
Parenteral nutrition (PN) is recommended in malnourished patients or those at risk of malnutrition in some conditions—such as gut functional unavailability or gut physical inaccessibility. The lipids are sepsis risk factors in patients receiving parenteral nutrition.

Uremic Toxins Control in CKD
Uremic toxins (UTs) are mainly produced by protein metabolized by the intestinal microbiota and converted in the liver or by mitochondria or other enzymes. The accumulation of UTs can damage the intestinal barrier integrity and cause vascular damage and progressive kidney damage. Together, these factors lead to metabolic imbalances, which in turn increase oxidative stress and inflammation and then produce uremia that affects many organs and causes diseases including renal fibrosis, vascular disease, and renal osteodystrophy. This article is based on the theory of the intestinal–renal axis, from bench to bedside, and it discusses nonextracorporeal therapies for UTs, which are classified into three categories: medication, diet and supplement therapy, and complementary and alternative medicine (CAM) and other therapies. The effects of medications such as AST-120 and meclofenamate are described. Diet and supplement therapies include plant-based diet, very low-protein diet, probiotics, prebiotics, synbiotics, and nutraceuticals. The research status of Chinese herbal medicine is discussed for CAM and other therapies. This review can provide some treatment recommendations for the reduction of UTs in patients with chronic kidney disease.

DNA Damage/Repair Management in Cancers
DNA damage is well recognized as a critical factor in cancer development and progression. DNA lesions create an abnormal nucleotide or nucleotide fragment, causing a break in one or both chains of the DNA strand. When DNA damage occurs, the possibility of generated mutations increases. Genomic instability is one of the most important factors that lead to cancer development. DNA repair pathways perform the essential role of correcting the DNA lesions that occur from DNA damaging agents or carcinogens, thus maintaining genomic stability. Inefficient DNA repair is a critical driving force behind cancer establishment, progression and evolution. A thorough understanding of DNA repair mechanisms in cancer will allow for better therapeutic intervention.

Lipolysis and Lipolytic Enzymes
In adipose triglyceride (AT), but also in other organs, three major enzymes are involved in lipolysis—adipose triglyceride lipase (ATGL), hormone-sensitive lipase (HSL), and monoacylglyceride lipase (MGL). TGs, specifically triolein, are very often used as a substrate to measure HSL and ATGL activity despite the fact that HSL hydrolase activity is up to 10-fold higher for diglycerides (DGs) compared to TGs. The activity of lipolysis is finely regulated by multiple signals, with catecholamines, insulin, growth hormone, and natriuretic peptides being the main hormonal regulators.

Effect of a Vegan Diet on Alzheimer’s Disease
A vegan diet tends to be plant-based, but plant-based diets are not vegan by definition. Regarding Alzheimer’s disease (AD) prevention, a vegan diet includes low levels of saturated fats and cholesterol, contributing to a healthy blood lipid profile.
