Chrysin attenuates epithelial prostatic hyperplasia in the ventral prostate of spontaneously hypertensive rats.

The aim of this study was to evaluate the effects of chrysin on the ventral prostate of spontaneously hypertensive rats (SHR). Ten-week-old male Wistar and SHR rats received 100 mg/kg/day of chrysin (TW and TSHR) or 200 µL/day of the dilution vehicle (CW and CSHR) for 70 days. After the treatment, the animals were euthanized and the prostates were dissected out, fixed, and processed for further morphological, immunohistochemical, and biochemical analyses.

Anti-inflammatory and antinociceptive effects, and safety toxicological profile of a new paracetamol analog, LQFM291.

In the scope of a research program with the goal of developing treatments for inflammatory diseases, the pharmacological evaluation of LQFM291, designed by molecular hybridization from butylated hydroxytoluene and paracetamol, was described. The antioxidant profile of LQFM291 was evaluated by electrochemical measurement. Also, acute or repeated treatments with equimolar doses to paracetamol were used to evaluate the antinociceptive and/or anti-inflammatory activities of LQFM291 in animal models.

In vivo effect of orally given polyvinyl alcohol/starch nanocomposites containing bioactive peptides from Phaseolus vulgaris beans.

In this study, a nanocomposite produced with a blend of polyvinyl alcohol and partially hydrolyzed starch from Solanum lycocarpum was used as a matrix to entrap natural bioactive peptides from Phaseolus vulgaris. The nanocomposites were characterized by dynamic light scattering, scanning electron microscopy, and field emission gun scanning electron microscopy. The nanocomposites were then orally administered to Wistar rats, and their absorption was determined using morphometric, histopathological, cytochemistry, transmission electron microscopy, and biochemical analysis.

Neonatal exposure to aluminum chloride disrupts branching morphogenesis and hormonal signaling of the ventral male prostate and female prostate of gerbils.

Backgroung: Exposure to environmental pollutants in critical developmental windows may predispose the prostate to permanent changes in its homeostasis. Thus, it is essential to know the effects that environmental toxics, such as aluminum, can cause during the development of this gland. The aim of this study was to evaluate the effects of neonatal aluminum exposure on the ventral male prostate and the female prostate of 15 days old gerbils.

Action of Brazilian propolis on hematological and serum biochemical parameters of Blue-fronted Amazons (Amazona aestiva, Linnaeus, 1758) in captivity.

The present study aimed to evaluate the effect of propolis use on hematological and serum biochemical parameters in Blue-fronted Amazons (Amazona aestiva). For this, 12 adult birds were distributed randomly into individual cages, divided into treatments with different propolis levels (A = 0.0%; B = 0.
