Brittany S Barros, Andrea L Zaenglein
The use of cosmeceuticals by patients with acne is common; however, their role is unclear and confusing, with many asking, "Do they really help acne?" Cosmeceuticals are intermediate products between prescription medications and cosmetics, available to consumers over the counter. These products are popular and may be used without the direct supervision of a dermatologist, creating a practice gap in educating patients. Herein, a variety of cosmeceuticals are discussed, including retinoids, niacinamide, and glycolic acid...

3-acetylpyridine (3-AP) is a metabolic antagonist used in research to decrease levels of nicotinamide (niacinamide) in laboratory animals. The administration of 3-AP followed by nicotinamide to rats leads to the selective destruction of neurons in the medial inferior olive, resulting in a loss of climbing fibers innervating cerebellar Purkinje cells and a consequent ataxia manifest by alterations in both balance and gait. Although 3-AP has also been administered to mice to destroy neurons in the inferior olive, there are limited studies quantifying the consequent effects on balance, and no studies on gait...

Bhavik Bhatt, Vijay Kumar
In the present work, the release mechanisms of active pharmaceutical ingredients (APIs) enclosed in self-pore forming regenerated cellulose (RC) two-piece hard shell capsules are described. The RC capsules were fabricated using a modified dip-coating approach, which yielded an assembled dosage form that was equivalent in size and shape to a conventional gelatin two-piece hard shell capsule. Drug release characteristics from RC capsules were evaluated using potassium chloride, diphenhydramine hydrochloride, tramadol hydrochloride, niacinamide, acetaminophen and ketoprofen as model APIs...

Blood and urine biochemistry screening tests are important for initial detection of diabetes, determination of severity of its complications, and monitoring of therapy. We evaluated the effects of aqueous chicory seed extract (CSE), on renal biochemical parameters, histology, and Na+/glucose cotansporters, SGLT1 and SGLT2 expression levels using metformin, and aspirin as controls. Late stage type 2 diabetes (LT2D; FBS, >300 mg/dl) and early stage type 2 diabetes (ET2D; FBS, 140-220 mg/dl) were induced in rats by streptozotocin (STZ group) and a combination of STZ and niacinamide (NIA/STZ group), respectively...

The association of bullous pemphigoid with melanoma remains controversial and poorly understood. Recent studies report the presence of the bullous pemphigoid antigen, BP180, in melanoma cells, yet not normal melanocytes, suggesting an underlying mechanism for cases of melanoma-associated bullous pemphigoid. We report on an 88-year-old woman who showed a temporal relationship between the development of bullous pemphigoid and melanoma. The patient did not receive programmed death ligand 1 inhibitor therapy and improved rapidly following complete excision of her melanoma, with clobetasol, doxycycline, and niacinamide...

New binuclear chromium (III) niacinamide compound with chemical formula [Cr2(Nic)(Cl)6(H2O)4]·H2O was obtained upon the reaction of chromium (III) chloride with niacinamide (Nic) in methanol solvent at 60°C. The proposed structure was discussed with the help of microanalytical analyses, conductivity, spectroscopic (FT-IR and UV-vis.), magnetic calculations, thermogravimetric analyses (TG/TGA), and morphological studies (X-ray of solid powder and scan electron microscopy. The infrared spectrum of free niacinamide in comparison with its chromium (III) compound indicated that the chelation mode occurs via both nitrogen atoms of pyridine ring and primary -NH2 group...

UNLABELLED: Glioblastoma multiforme (GBM) is a CNS (central nervous system) malignancy with a low cure rate. Median time to progression after standard treatment is 7 months and median overall survival is 15 months [1]. Post-treatment vasculogenesis promoted by recruitment of bone marrow derived cells (BMDCs, CD11b+ myelomonocytes) is one of main mechanisms of GBM resistance to initial chemoradiotherapy treatment [2]. Local secretion of SDF-1, cognate ligand of BMDCs CXCR4 receptors attracts BMDCs to the post-radiation tumor site...

Hyperpigmentation disorders constitute important medical and aesthetical conditions. Dark areas or dark spots on the skin result from inappropriate amount and/or deposition of skin pigments - melanins. Several depigmenting agents, such as kojic acid, arbutin, aloesin, ellagic acid, resveratrol, azelaic acid, niacinamide, tretinoin, glycolic acid, lactic acid, and citric acid, have already been identified and are used in topical drugs or cosmetic formulations for the treatment of hyperpigmentations. However, these compounds are characterized by insufficient effectiveness and multiple adverse effects...

Inflammation is an important immune response; however, excessive inflammation causes severe tissue damages and secondary inflammatory injuries. The long-term and ongoing uses of routinely used drugs such as non-steroidal anti-inflammatory drugs (NSAIDS) are associated with serious adverse reactions, and not all patients have a well response to them. Consequently, therapeutic products with more safer and less adverse reaction are constantly being sought. Radix Bupleuri, a well-known traditional Chinese medicine (TCM), has been reported to have anti-inflammatory effects...

IMPORTANCE: Metabolomics is the broad and parallel study of metabolites within an organism and provides a contemporaneous snapshot of physiologic state. Use of metabolomics in the clinical setting may help achieve precision medicine for those who have experienced trauma, where diagnosis and treatment are tailored to the individual patient. OBJECTIVE: To examine whether metabolomics can (1) distinguish healthy volunteers from trauma patients and (2) quantify changes in catabolic metabolites over time after injury...

OBJECTIVE: Evidence suggests prolonged exposure to lower levels of low-density lipoprotein cholesterol (LDL-C), starting at a younger age, substantially lowers cardiovascular (CV) risk. Accordingly, the CV pandemic affecting younger population in low- to low-middle-income countries, where statin usage is poor even in secondary prevention, may benefit from lipid-lowering nutritional products, as nutritional intervention is generally preferred in these cultures. However, the safety and efficacy of such preparations have not been systematically tested...

Although some physiological and pathological function parameters of hepatitis and liver cancer have been investigated in relation to hispidulin (5,7,4'-trihydroxy-6-methoxyflavone), the changes of small metabolites in biofluids have been reported rarely. Recent research has shown that metabolic profiling with ultra-high-performance liquid chromatography coupled to quadrupole time of flight mass spectrometry (UHPLC-QTOF/MS) coupled with multivariate statistical analysis provides a good understanding of hispidulin effects on mice vaccinated intraperitoneally with H22 tumor cells...
