Impact of Herbal Therapies on COVID-19 and Influenza
Synthetic antivirals and corticosteroids have been used to treat both influenza and the SARS-CoV-2 disease named COVID-19. However, these medications are not always effective, produce several adverse effects, and are associated with high costs. Medicinal plants and their constituents act on several different targets and signaling pathways involved in the pathophysiology of influenza and COVID-19. Medicinal plants, in different formulations, can help to decrease viral spread and the time until full recovery. Plants reduced the incidence of acute respiratory syndromes and the symptom scores of the illnesses. Moreover, plants are related to few adverse effects and have low costs. In addition to their significance as natural antiviral agents, medicinal plants and their bioactive compounds may exhibit low bioavailability.

Effect of Long-Acting Muscarinic Antagonists on Asthma
Long-acting muscarinic antagonists (LAMAs) are a class of inhalers that has recently been included as add-on therapy in the GINA guidelines, either in a single inhaler device with inhaled corticosteroids plus long-acting β2-agonists (ICS + LABA) (closed triple inhaler therapy) or in a separate one (open triple inhaler therapy).

Physicochemical Characterization of Aluminum Adjuvants
Aluminum-based adjuvants will continue to be a key component of currently approved and next generation vaccines. Their large adsorptive capacity allows the combination with other immunostimulatory molecules to create a toolbox of adjuvants for selective vaccine applications. The widespread use of aluminum adjuvants is due to their excellent safety profile, which has been established through the use of hundreds of millions of doses in humans over many years, low cost, and extensive experience with licensure through regulatory agencies.

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.
