Brain Endothelial Cell Activation and Dysfunction (BECact/dys)
Embryonic genetic mechanisms are present in the brain and ready to be placed into action upon cellular injury, termed the response to injury wound-healing (RTIWH) mechanism. When injured, regional brain endothelial cells initially undergo activation and dysfunction with initiation of hemostasis, inflammation (peripheral leukocytes, innate microglia, and perivascular macrophage cells), proliferation (astrogliosis), remodeling, repair, and resolution phases if the injurious stimuli are removed.

Matrix Metalloproteinases Inhibitors in Cancer Treatment
Matrix metalloproteinases (MMPs) are a member of the enzyme group that is capable of protein degradation. MMPs are recognized as metalloproteinases because they require either zinc and calcium to perform their functions.

Omega-3 and Omega-6 Fatty Acids
Omega-3 fatty acids v(ω-3 FAs) such as EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) and omega-6 fatty acids (ω-6 FAs) such as linoleic acid and arachidonic acid are important fatty acids responsible for positive effects on human health. The main sources of ω-3 FAs and ω-6 FAs are marine-based products, especially fish oils.

Pediatric-Type Diffuse Low-Grade Glioma
Pediatric-type diffuse low-grade glioma (LGG) are the most common pediatric brain tumor, accounting for approximately one-third of all cases. These tumors are designated as WHO grade 1 or 2 and encompass a wide array of histology and varying molecular backgrounds. Many of these tumors are incidentally found on head imaging with intervention needed when adverse symptoms present or when found to have progressive disease. Pediatric diffuse LGGs are primarily heterogenous in nature and can be molecularly classified into distinct subgroups; diffuse astrocytoma MYB- or MYBL1-altered, angiocentric glioma, polymorphous low-grade neuroepithelial tumors, and diffuse LGG MAPK pathway-altered.

Associations of Linoleic Acid Intake and Chronic Disease
The intake of linoleic acid (LA) has increased dramatically in the standard American diet. LA is generally promoted as supporting human health, but there exists controversy regarding whether the amount of LA currently consumed in the standard American diet supports human health. While LA is considered to be an essential fatty acid and support health when consumed in modest amounts, an excessive intake of LA leads to the formation of oxidized linoleic acid metabolites (OXLAMs), impairments in mitochondrial function through suboptimal cardiolipin composition, and likely contributes to many chronic diseases that became an epidemic in the 20th century, and whose prevalence continues to increase. As LA consumption increases, the potential for OXLAM formation also increases. OXLAMs have been associated with various illnesses, including cardiovascular disease, cancer, and Alzheimer’s disease, among others. Lowering dietary LA intake can help reduce the production and accumulation of OXLAMs implicated in chronic diseases.

Promising Highly Targeted Therapies for Cholangiocarcinom
To overcome the poor prognosis of cholangiocarcinoma (CCA), highly targeted therapies, such as antibody-drug conjugates (ADCs), photodynamic therapy (PDT) with/without systemic chemotherapy, and experimental photoimmunotherapy (PIT), have been developed. Three preclinical trials have investigated the use of ADCs targeting specific antigens, namely HER2, MUC1, and glypican-1 (GPC1), for CCA. Trastuzumab emtansine demonstrated higher antiproliferative activity in CCA cells expressing higher levels of HER2. PDT is effective in areas where appropriate photosensitizers and light coexist. Its mechanism involves photosensitizer excitation and subsequent reactive oxygen species production in cancer cells upon irradiation. Hematoporphyrin derivatives, temoporfin, phthalocyanine-4, talaporfin, and chlorine e6 derivatives have mainly been used clinically and preclinically in bile duct cancer. PIT is the most novel anti-cancer therapy developed in 2011 that selectively kills targeted cancer cells using a unique photosensitizer called “IR700” conjugated with an antibody specific for cancer cells. PIT is currently in the early stages of development for identifying appropriate CCA cell targets and irradiation devices. Future human and artificial intelligence collaboration has potential for overcoming challenges related to identifying universal CCA cell targets. This could pave the way for highly targeted therapies for CCA, such as ADC, PDT, and PIT.

Role of Melatonin in Fibromyalgia
Fibromyalgia syndrome (FMS) is a chronic widespread pain syndrome that is accompanied by fatigue, sleep disturbances, anxiety, depression, lack of concentration, and neurocognitive impairment. Melatonin is a low-molecular-weight indolamine (N-acetyl-5-methoxytryptamine) synthesized from the amino acid L-tryptophan, which is present in animals, plants, and even unicellular organisms. Melatonin is produced in the main cell of the pineal gland, the pinealocyte, and is controlled in mammals via ambient light.

Etiology and Pathogenesis of EC in Fertile Women
Endometrial cancer (EC) affects the lining of the uterus and is usually diagnosed in postmenopausal women, but about 5% of cases occur in women under 40, and approximately 20% of cases are diagnosed before menopause.

Drug Delivery Systems for Uveitis and Neuro-Ophthalmologic Conditions
To circumvent these constraints, the development of biodegradable nano-based drug delivery systems (DDS) has gained prominence. These systems promise extended residence time in ocular tissues, improved penetration through ocular barriers, and are composed of nanosized, biodegradable polymers, thereby diminishing the risk of toxicity and adverse reactions.
