A series of polypyrrole doped TiO-SiO nanohybrids (Ppy/TS NHs) were synthesized thru in-situ oxidation polymerization by varying weight ratio of pyrrole. The structural analysis of NHs were characterized by X-ray Diffraction (XRD) spectra, UV-visible (UV-Vis) spectra and X-ray Photoelectron spectra (XPS) confirmed synthesis of nanomaterials. Surface and morphological study done by adopting, Scanning Electron Microscopy (SEM), Energy Dispersive Spectroscopy (EDS), Transmittance Electron Microscopy (TEM) and Brunauer-Emmett-Teller (BET) analysis confirmed the homogenous distribution, nano range size formation and mesoporous nature of nanohybrids. Further, electrochemical behavior of synthesized NHs investigated by adopting Electrochemical Impedance Spectroscopy (EIS) showed good kinetic behaviour and electron transport tendency. The nanohybrids and precursors were examined for photocatalytic degradation of methylene blue (MB) dye and revealed enhanced degradation tendency for the NHs series photocatalysts. It was found that variation of pyrrole (0.1 to 0.3 g) to TS nanocomposites (TS Nc) increased the photocatalytic potential of TS Nc. The maximum photodegradation efficacy was found to be 90.48% in 120 min for Ppy/TS0.2 NHs under direct solar light. Additionally, Ppy/TS0.2 NHs performed appreciably towards antibacterial studies against some Gram-positive and Gram-negative deleterious bacteria, Escherichia coli, Klebsiella pneumoniae, Staphylococcus aureus, Shigella flexneri microbes.

Pili trianguli et canaliculi syndrome is a rare hair shaft disorder characterized by frizzy hair that cannot be smoothed flat. Affected hair shafts are triangular or kidney-shaped with longitudinal grooving. Diagnosis typically requires electron microscopy, which may be cost-prohibitive, or alternatively, the distinctive features of hair shafts can be identified through histological examination of cross sections, that is time-consuming.

Background: Cystic echinococcosis (CE) is a common neglected parasitic disease. Nanoparticles containing drugs have been widely utilized in various formulations for several purposes, including improving the bioavailability of drugs by increasing the solubility and dissolution rate of the nanoparticles. The purpose of this study was to evaluate the effects of solid lipid nanoparticles containing albendazole and conjugated to albumin (B-SLN + ABZ) as a novel treatment approach for hydatid cysts in vivo.

Background: Acanthocephalans (thorny headed worms) of the genus Pseudoacanthocephalus mainly parasitize amphibians and reptiles across the globe. Some species of the genus Pseudoacanthocephalus also can accidentally infect human and cause human acanthocephaliasis. Current knowledge of the species composition of the genus Pseudoacanthocephalus from amphibians and reptiles in China is incomplete.

Objective: This study aims to elucidate the mechanisms by which nanovesicles (NVs) transport curcumin(CUR) across the blood-brain barrier to treat hypothalamic neural damage induced by heat stroke by regulating the expression of poly(c)-binding protein 2 (PCBP2).
Methods: Initially, NVs were prepared from macrophages using a continuous extrusion method. Subsequently, CUR was loaded into NVs using sonication, yielding engineered cell membrane Nanovesicles loaded with curcumin (NVs-CUR), which were characterized and subjected to in vitro and in vivo tracking analysis.
