Clinical Efficacy and Safety, Interchangeability of Biosimilars
Clinical safety and efficacy studies add substantial cost and time to the approval of biosimilars. However, this argument will have little weight if these studies were able to add additional value over and above the rest of the testing. Interchangeability is a legally defined path in the US biosimilar guidance.

The Potential Role of Toll-like Receptors in Schizophrenia
Toll-like receptors (TLRs) are a family of pattern recognition receptors (PRRs) ubiquitously expressed in the human body. They protect the brain and central nervous system from self and foreign antigens/pathogens. The immune response elicited by these receptors culminates in the release of cytokines, chemokines, and interferons causing an inflammatory response, which can be both beneficial and harmful to neurodevelopment. Such changes due to TLRs are shown to be associated with alterations in cognitive functions in various neurodegenerative and psychiatric disorders, and schizophrenia is one such disorder where multiple genetic and environmental factors contribute to alterations associated with TLRs.

Cell-Penetrating Peptides Applications
Since their identification over twenty-five years ago, the plethora of cell-penetrating peptides (CPP) and their applications has skyrocketed. These 5 to 30 amino acid in length peptides have the unique property of breaching the cell membrane barrier while carrying cargoes larger than themselves into cells in an intact, functional form. CPPs can be conjugated to fluorophores, activatable probes, radioisotopes or contrast agents for imaging tissues, such as tumors. There is no singular mechanism for translocation of CPPs into a cell, and therefore, many CPPs are taken up by a multitude of cell types, creating the challenge of tumor-specific translocation and hindering clinical effectiveness. Varying strategies have been developed to combat this issue and enhance their diagnostic potential by derivatizing CPPs for better targeting by constructing specific cell-activated forms. These methods are currently being used to image integrin-expressing tumors, breast cancer cells, human histiocytic lymphoma and protease-secreting fibrosarcoma cells, to name a few. Additionally, identifying safe, effective therapeutics for malignant tumors has long been an active area of research. CPPs can circumvent many of the complications found in treating cancer with conventional therapeutics by targeted delivery of drugs into tumors, thereby decreasing off-target side effects, a feat not achievable by currently employed conventional chemotherapeutics. Myriad types of chemotherapeutics such as tyrosine kinase inhibitors, antitumor antibodies and nanoparticles can be functionally attached to these peptides, leading to the possibility of delivering established and novel cancer therapeutics directly to tumor tissue.

Cannabidiol as a Therapeutical Tool in Dentistry
The medical use of cannabis has a very long history. In the use of cannabinoids, the oral mucosa is the tissue that primarily comes into contact with them and interacts with them. Cannabidiol (CBD) itself is not responsible for the psychotropic effects of cannabis, since it does not produce the typical behavioral effects associated with the consumption of this drug.

URAT1 and Other UA Transporters with Metabolic Syndrome
Urate transporter 1 (URAT1), which is a urate anion exchanger that regulates serum uric acid (UA) levels in the human kidney, was identified in 2002, and it has been targeted by uricosuric agents. In humans, renal reabsorption of UA into the blood plays an important role in controlling serum UA levels. The UA exchange is mediated by various molecules expressed in the renal proximal tubule. UA enters the proximal tubule epithelial cells in exchange for monocarboxylate via apical URAT1 and for dicarboxylate via the apical organic anion transporter (OAT) 4. OAT1 and OAT3 on the basolateral membrane of epithelial cells transport UA from the renal interstitial into the renal proximal tubule epithelial cells. Renal UA reabsorption is mainly mediated by URAT1 and glucose transporter 9 (GLUT9). Apical GLUT9b plays a significant role in UA reabsorption; the reabsorbed UA exits the proximal tubule epithelial cells into the blood through basolateral GLUT9a. The ATP-binding cassette transporter G2 (ABCG2) has been identified as a high-capacity UA exporter that mediates renal and/or extra-renal (intestinal) UA excretion.

Obesity Treating Natural Products
Obesity is a global issue faced by many individuals worldwide. However, no drug has a pronounced effect with few side effects. Green tea, a well-known natural product, shows preventive effects against obesity by decreasing lipogenesis and increasing fat oxidation and antioxidant capacity. In contrast, other natural products are known to contribute to obesity. The natural products were classified as single compounds, foods, teas, fruits, herbal medicines—single extract, herbal medicines—decoction, and herbal medicines—external preparation. Then, the mechanisms of these medicines were organized into lipid metabolism, anti-inflammation, antioxidation, appetite loss, and thermogenesis. This research aimed to assess the efficacy and mechanisms of effective natural products in managing obesity. Several clinical studies reported that natural products showed antiobesity effects, including Coffea arabica (coffee), Camellia sinensis (green tea), Caulerpa racemosa (green algae), Allium sativum (garlic), combined Ephedra intermedia Schrenk, Thea sinensis L., and Atractylodes lancea DC extract (known as Gambisan), Ephedra sinica Stapf, Angelica Gigantis Radix, Atractylodis Rhizoma Alba, Coicis semen, Cinnamomi cortex, Paeoniae radixalba, and Glycyrrhiza uralensis (known as Euiiyin-tang formula).

Alpha-Amylase Inhibitory Metabolites from Pericarps of Garcinia mangostana
Two new benzophenones and five known metabolites were purified from Garcinia mangostana ((GM) pericarps. They were characterized by various spectral techniques. Compounds 6 and 7 displayed AAI activity. They also exhibited highly negative docking scores, when complexed with 5TD4. Their complexes with the α-amylase were found to be stable over the course of 50 ns. These results supported the previous reports that GM can potentially represent an appealing treatment of diabetes and its related disorders.

Prebiotic Boron-Containing Compounds in Complex Regional Pain Syndrome
Studies have demonstrated that individuals with complex regional pain syndrome (CRPS) often exhibit dysbiosis, with imbalances in beneficial and pathogenic gut bacteria. Dysbiosis can lead to increased gut permeability and systemic inflammation, contributing to the chronic pain experienced in CRPS. B, an essential trace element, has shown promise in modulating the gut microbiome positively and exerting anti-inflammatory effects. Preclinical and clinical studies suggest that B supplementation may alleviate neuropathic pain and improve CRPS symptoms by restoring microbiota balance and reducing inflammation.

Enhanced Drug Penetration and Retention in Airway Mucosa
Airway mucus is a complex viscoelastic gel mainly composed of water, glycoproteins, lipids, enzymes, minerals, etc. Among them, glycoprotein is the main factor determining mucus-gel-like rheology. Airway mucus forms a protective barrier by secreting mucin, which represents the absorption barrier, especially for more lipophilic drugs. It rapidly clears the drug from the airways through physiological mucus clearance mechanisms, so the drug does not remain in the lungs or reach the airway epithelial tissue for a long time.
