Poloxamer 188 stabilized poly (ε-caprolactone) microspheres of voriconazole for targeting pulmonary aspergillosis.

Aim: Voriconazole (VRZ) is highly effective in treating invasive pulmonary aspergillosis (IPA), in addition to hepatotoxicity. Therefore, the current study focuses on the development and characterization of voriconazole-loaded microspheres (VRZ@PCL MSPs) to augment pulmonary localization and antifungal efficacy.

Methods: VRZ@PCL MSPs were fabricated by using the o/w emulsion method.

Garcinol enriched fraction of Garcinia morella (Gaertn.) Desr. fruit rind improves gut health and reduces the risk of nonalcoholic fatty liver disease by regulating PCK1/ACC/SREBP1/FASn pathway in a mouse model.

Nonalcoholic fatty liver disease (NAFLD), a fast-emerging global burden, is an umbrella term for several liver manifestations that result in excessive accumulation of fat in the liver. NAFLD leads to gut microbiome dysbiosis, loss in gut epithelia, increased gut permeability, etc. The limited availability of registered drugs for NAFLD highlights the urgent need to focus on understanding its pathogenesis and discovering new treatments, including the potential exploration of herbal therapies for managing the condition.

sp. MNP32, a forest-dwelling endowed with potent antibacterial metabolites.

The isolate, MNP32 was isolated from the Manas National Park of Assam, India, located in the Indo-Burma biodiversity hotspot region of Northeast India. Morphological observations and molecular characterization revealed its identity to be sp. with a 99.

Vitamin B12-Immobilized Graphene Oxide for Efficient Electrocatalytic Carbon Dioxide Reduction Reaction.

A naturally occurring water-soluble cobalt-complex cyanocobalamin (Vitamin B12) has been identified as a new and efficient electrocatalyst for the CO -to-CO reduction reaction in aqueous solution. Heterogeneous B12-electrocatalysts prepared by a simple electrochemical immobilization technique on graphene-oxide (GO)-modified glassy carbon and carbon paper (CP) electrodes, without any non-degradable polymer-binders, showed a highly stable and well-defined surface-confined redox peak at E'=-0.138 V vs.

Nickel sulfide-incorporated sulfur-doped graphitic carbon nitride nanohybrid interface for non-enzymatic electrochemical sensing of glucose.

A nickel sulfide-incorporated sulfur-doped graphitic carbon nitride (NiS/S-g-CN) nanohybrid was utilized as an interface material for the non-enzymatic sensing of glucose in an alkaline medium (0.1 M NaOH). The precursors used in the preparation of NiS/S-g-CN hybrid were thiourea and nickel nitrate hexahydrate as the sulfur and nickel sources, respectively.

Achieving a Stable High Surface Excess of Glucose Oxidase on Pristine Multiwalled Carbon Nanotubes for Glucose Quantification.

In this study, glucose oxidase (GOx) immobilization onto ten different types of carbon modified GCEs and its direct electron transfer (DET) were investigated. A maximum amount of GOx immobilization (Γ) of 2.9 nM/cm was achieved on the pristine multiwalled carbon nanotubes (PMWCNT) with high stability.

Synthesis, Characterization, and Biomedical Applications of an Alkylated Quercetin-Gadolinium Complex.

Flavonoids and their derivatives have been extensively studied for their pharmaceutical applications due to their antioxidant and anti-inflammatory properties. The coordination complexes of several flavonoids have demonstrated DNA binding ability that can confer anticancer properties. The structure of the flavonoid has a pronounced influence on its pharmacological properties.

A blood-serum sulfide selective electrochemical sensor based on a 9,10-phenanthrenequinone-tethered graphene oxide modified electrode.

The sulfide ion and its associated species (HS and HS) are widely referred to as toxic chemicals. However, at concentrations of ∼10-100 μM, it serves as a neurotransmitter and signaling agent in biological systems. Abnormalities in blood serum sulfide can be an indication of several diseases, including diabetes, wherein there is a significant reduction in the sulfide ion concentration (<10 μM).

In Situ Structural Elucidation and Selective Pb Ion Recognition of Polydopamine Film Formed by Controlled Electrochemical Oxidation of Dopamine.

Owing to the versatility and biocompatibility, a self-polymerized DA (in the presence of air at pH 8.5 tris buffer solution) as a polydopamine (pDA) film has been used for a variety of applications. Indeed, instability under electrified condition (serious surface-fouling) and structural ambiguity of the pDA have been found to be unresolved problems.

Oral Disintegration Tablets of Stavudine for HIV Management: A New Technological Approach.

Stavudine oral disintegration tablets were formulated to minimize the bitter taste and to reduce the first-pass hepatic metabolism. The various precompression parameters like the angle of repose, bulk density, compressibility index and Hausner's ratio were determined for the powder blend. In this study, 14 formulations of stavudine oral disintegration tablet were prepared by direct compression method.
