Elevated Procalcitonin and COVID-19
PCT is a precursor of calcitonin, which is secreted by neuroendocrine cells such as C cells of the thyroid and pancreatic tissues.  PCT plays an important role in the diagnosis of systemic bacterial infection.  Elevated serum PCT levels have also been reported in patients with pulmonary infection. Additionally, the positive feedback between procalcitonin and proinflammatory cytokines subsequently culminates in a severe systemic inflammatory response.

Hepatic CYP2E1 in Causal Toxicity and Treatment Options
Cytochrome P450 2E1 (CYP2E1), one of the major metabolizing enzymes in humans, is mainly expressed in the liver. Alcohol and several therapeutic drugs, including acetaminophen, are metabolized by CYP2E1 into toxic compounds. At low levels, these compounds are not detrimental, but higher sustained levels of these compounds can lead to life-long problems such as cytotoxicity, organ damage, and cancer. Furthermore, CYP2E1 can facilitate or enhance the effects of alcohol-drug and drug-drug interactions.

Fluoroquinolones Used in Therapy
Antibacterial fluoroquinolones (FQs) are frequently used in treating infections. However, the value of FQs is debatable due to their association with severe adverse effects (AEs). The Food and Drug Administration (FDA) issued safety warnings concerning their side-effects in 2008, followed by the European Medicine Agency (EMA) and regulatory authorities from other countries.

Solid Lipid Nanoparticles/Nanostructured Lipid Carriers in Acne VulgarisTreatment
Acne vulgaris (acne) is one of the most common dermatological problems affecting adolescents and young adults. Although acne may not lead to serious medical complications, its psychosocial effects are tremendous and scientifically proven. The first-line treatment for acne is topical medications composed of synthetic compounds, which usually cause skin irritation, dryness and itch. Therefore, naturally occurring constituents from plants (phytochemicals), which are generally regarded as safe, have received much attention as an alternative source of treatment. However, the degradation of phytochemicals under high temperature, light and oxygen, and their poor penetration across the skin barrier limit their application in dermatology. Encapsulation in lipid nanoparticles is one of the strategies commonly used to deliver drugs and phytochemicals because it allows appropriate concentrations of these substances to be delivered to the site of action with minimal side effects. Solid lipid nanoparticles (SLNs) and nanostructured lipid carriers (NLCs) are promising delivery systems developed from the combination of lipid and emulsifier. They have numerous advantages that include biocompatibility and biodegradability of lipid materials, enhancement of drug solubility and stability, ease of modulation of drug release, ease of scale-up, feasibility of incorporation of both hydrophilic and lipophilic drugs and occlusive moisturization, which make them very attractive carriers for delivery of bioactive compounds for treating skin ailments such as acne.

Biomarkers Derived from the Molecular Profiling of TNBC
Triple-negative breast cancer (TNBC), the most aggressive and heterogenous type of cancer, lacks the expression of hormones like estrogen, progesterone, and human epidermal growth receptor-2, making chemotherapy the only treatment regimen against TNBC. To overcome the problem faced during chemotherapy, and to address the heterogeneity of TNBC, targeted therapy emerged based on the molecular profiling of TNBC. Several biomarkers are used as targets for the precision therapy in TNBC, including EGFR, VGFR, TP53, interleukins, insulin-like growth factor binding proteins, c-MET, androgen receptor, BRCA1, glucocorticoid, PTEN, ALDH1, etc.

Definition and Characterization of Coronary Calcification
Coronary artery calcification is increasingly prevalent in our patient population. It significantly limits the procedural success of percutaneous coronary intervention and is associated with a higher risk of adverse cardiovascular events both in the short-term and long-term.

Phytochemistry, Medicinal Uses and Pharmacological Activities of Parkia
Parkia is a genus of flowering plants belonging to the family Fabaceae (subfamily, Mimosoideae) with pan-tropical distribution. The word Parkia was named after the Scottish explorer Mungo Park, who drowned in the Niger River, Nigeria in January 1805. The genus Parkia (Fabaceae, Subfamily, Mimosoideae) comprises about 34 species of mostly evergreen trees widely distributed across neotropics, Asia, and Africa.

The Pharmacological Therapies of Huntington’s Chorea
Huntington’s Disease (HD) is an autosomal, dominantly inherited neurodegenerative disorder caused by an expansion of the CAG repeat in the huntingtin (HTT) gene. The disease generally manifests during mid-life and is clinically characterized by involuntary movements (chorea), psychiatric and behavioral symptoms, and cognitive decline. To this date, no cure or disease-modifying therapy exists. However, a wide variety of pharmacological therapies are used to improve quality of life.
