Phylogenetic analysis and homology modelling of a new Cry8A crystal protein expressed in a sporulating soil bacterium.

Cry proteins, commonly found in Gram-positive soil bacteria, are used worldwide as aerial sprays or in transgenic plants for controlling crop pest populations and insect vectors. Via PCR analysis, a spore producing soil isolate (BV5) was speculated to encode a Cry gene. Partial nucleotide sequence of the amplified PCR fragment showed homology with the Cry8 genes present in GenBank.

Combination of Apigenin and Melatonin with nanostructured lipid carriers as anti-inflammatory ocular treatment.

Ocular inflammation is a complex pathology with limited treatment options. While traditional therapies have side effects, novel approaches, such as natural compounds like Apigenin (APG) and Melatonin (MEL) offer promising solutions. APG and MEL, in combination with nanostructured lipid carriers (NLC), may provide a synergistic effect in treating ocular inflammation, potentially improving patient outcomes and reducing adverse effects.

A new coamorphous ethionamide with enhanced solubility: Preparation, characterization, in silico pharmacokinetics, and controlled release by encapsulation.

This study reports the synthesis and the experimental-theoretical characterization of a new coamorphous system consisting of ethionamide (ETH) and mandelic acid (MND) as a coformer. The solid dispersion was synthesized using the slow solvent evaporation method in an ethanolic medium. The structural, vibrational, and thermal properties of the system were characterized.

Transmissible venereal tumour with encephalic metastasis in dogs.

From January 2000 to December 2023 the Laboratory of Animal Pathology of the Federal University of Campina Grande received 6,218 canine autopsy and biopsy submissions, with six (0.09%) autopsy cases diagnosed as transmissible venereal tumour (TVT) with encephalic metastases. The mean age of affected dogs (four females and two males) was 7 years.

Multifunctional Indomethacin Conjugates for the Development of Nanosystems Targeting Cancer Treatment.

Purpose: It is well known that the nonsteroidal anti-inflammatory drug (NSAID) indomethacin (IND) exhibits significant anticancer potential reported not only by in vitro and in vivo studies, but also in clinical trials. Despite promising results, IND is not widely used as an adjunctive agent in cancer therapy due to the occurrence of several gastrointestinal side effects, primarily after oral administration. Therefore, this study aimed to develop a nanosystem with reduced toxicity and risk of side effects for the delivery of IND for cancer treatment.
