As nanocarriers of a new generation, biomimetic nanovesicles are an emerging class of therapeutic tools whose surface is integrated or fabricated with biomaterials capable of mimicking the biological features and functions of native cells. Thanks to this, biomimetic nanovesicles, in particular, those made by plasma membrane moieties, possess greatly improved biocompatibility, high target specificity, a long retention time, and minimal undesired immune responses. For these reasons, a multitude of progenitor cells including cancer ones were employed as templates to generate biomimetic or membrane-camouflaged nanovesicles hosting different therapeutic compounds.

Article Synopsis
  • The study aimed to evaluate outcomes in patients with tumors in the third ventricle by analyzing surgical interventions performed at Loyola University Medical Center from 1986 to 2021.
  • A total of 97 patients underwent 123 surgeries, with the results indicating that a higher extent of tumor removal (EOR) correlated with improved patient performance status post-surgery.
  • No significant differences were found between the outcomes of open versus endoscopic surgical techniques, suggesting that the type of approach may not impact long-term recovery as much as the extent of tumor resection.

The present study assessed the diet characteristics, trophic guild structure, and microplastics (MPs) ingestion by a group of fish sourced from the tidal creeks of the Mumbai coast along the Eastern Arabian Sea. The diet patterns were characterized using gastro-somatic index (GaSI), relative length of gut (RGL), diet overlap (α), diet breadth (B), and relative abundance of food items (%IOP), with a special emphasis on MPs contamination. The findings revealed that teleost and shrimps are the most preferred food items for these species.

Grass carp intestinal waste-mediated biosynthesized nanosilver (AgNPs) was valorized using guaran and zeolite matrices, resulting in AgNPs-guaran, AgNPs-zeolite, and AgNPs-guaran -zeolite composites. The valorized products were examined using Environmental Scanning Electron Microscopy, Energy Dispersive X-ray analysis and X-ray Diffraction analysis to confirm uniform dispersion and entrapment of AgNPs within the matrixes. These valorized products were evaluated for their efficacy in detoxifying the ubiquitous and toxic hexavalent chromium (Cr) in aquatic environments, with Anabas testudineus exposed to 2 mg l of Cr for 60 days.

We studied the effect of shade on the phenology, growth, berry yield, and chemical content of two common blueberry species ( and ) in Northwestern Ontario. We hypothesized that high shade would delay vegetative and reproductive phenology and decrease berry yield by increasing resource allocation to vegetative vs. reproductive growth, whereas moderate shade would increase berry phenolic content and antioxidant capacity.

Column purchasing cost is an important issue for an analyst to analyze complex sample matrices. Here, we report the development of an amino acid (β-alanine)-derived stationary phase (Sil-Ala-C12) with strategic and effective interaction sites (amide and urea as embedded polar groups with C12 alkyl chain) able to separate various kinds of analytes. Owing to the balanced hydrophobicity and hydrophilicity of the phase, it showed exceptional separation abilities in both reversed-phase high-performance liquid chromatography (RP-HPLC) as a hydrophobic phase and hydrophilic interaction chromatography (HILIC) as a hydrophilic phase.

Article Synopsis
  • The study explores using poultry intestines to create stable silver nanoparticles (AgNPs) and assess their effects on fish physiology.
  • The toxicity tests on the fish species Anabas testudineus indicated a lethal concentration (LC) value of 25.46 mg/l, with subsequent exposure to lower concentrations over 60 days revealing dose-dependent stress responses.
  • Findings show silver accumulates in various organs but not in muscle tissue, suggesting the fish can detoxify over time, and specific lower concentrations of AgNPs may not induce significant stress, highlighting potential applications in aquaculture.

The kukri snakes of the genus Fitzinger, 1826 reach the westernmost limits of their distribution in Middle and Southwest Asia (Afghanistan, Iran, and Turkmenistan), and the Palearctic portions of Pakistan. In this article, we review the systematics and distribution of the two species native to this region, (Shaw, 1802) and (Jerdon, 1853) based on an integrative approach combining morphological, molecular, and species distribution modeling (SDM) data. Phylogenetic analyses recover populations from Iran and Turkmenistan in a clade with the species complex, rendering the former species paraphyletic relative to stricto on the Indian subcontinent.
