Role of the endocannabinoid system in gonadal development: Implications for endocrine disruption and reproductive toxicity.

The endocannabinoid system (ECS) plays a pivotal role in reproductive physiology, including gonadal development, though its influence on testis and ovary development has only recently gained attention. The ECS comprises lipid-derived ligands such as anandamide (AEA) and 2-arachidonoylglycerol (2-AG), along with cannabinoid receptors CB1 and CB2, which are expressed in various gonadal cells. Emerging research indicates that ECS signaling is critical for testosterone synthesis and gonadal cell proliferation and differentiation.

Discriminatory dose of nitroxynil and albendazole sulfoxide using a modified egg hatch test of Fasciola hepatica.

Fasciolosis is a food-borne anthropozoonotic disease caused by Fasciola spp. that affects multiple hosts, including ruminants and humans. In vitro testing of anthelmintics is of interest to establish the drug's activity without the need for time-consuming and expensive in vivo assays.

Comparative analysis of extracellular vesicles miRNAs (EV-miRNAs) and cell-free microRNAs (cf-miRNAs) reveals that EV-miRNAs are more promising as diagnostic and prognostic biomarkers for prostate cancer.

MicroRNAs can be found intracellularly incorporated into extracellular vesicles (EV-miRNAs) or extracellularly as cell-free miRNAs (cf-miRNAs). This study aimed to compare the diagnostic and prognostic potential of four miRNAs with recognized roles in prostate cancer as cf-miRNAs and EV-miRNAs, obtained from liquid biopsies (LB). Total RNA was isolated from whole plasma and plasma EVs from 15 controls (CTR) and 30 patients (20 with localized prostate cancer (PCa), 10 with metastatic prostate cancer (mPCa)).

Sustainable assessment of ultrasound-assisted extraction of anthocyanins with bio-based solvents for upgrading grape pomace Cabernet Sauvignon derived from a winemaking process.

This work assessed the efficiency and sustainability of ultrasound-assisted extraction (UAE) of anthocyanins from grape pomace using bio-based solvents: Ethanol, Isopropanol, Propylene-glycol, and Ethylene-glycol at different concentrations (50 and 100 % v/v) and temperatures (25 °C and 50 °C). Higher ultrasonic intensities (UI) were obtained at 50 °C and 50 % v/v by decreasing solvents viscosities. Under these conditions, anthocyanin extractions were performed with different combinations of solvent to liquid ratio (SLR) at 1:10 and 1:50 g/mL, and UI (3.

Trazodone-gabapentin association increases sedation scores with mild hemodynamic and echocardiographic impact in healthy cats.

Despite the increasing use of drugs to facilitate feline management in veterinary care, there is still a lack of information on the anxiolytic and sedative effects and their specific physiological impacts. We aimed to compare the sedative, hematological, biochemical and cardiovascular effects of oral single-dose trazodone and gabapentin, alone or in combination, in 8 healthy adult mixed-breed domestic cats on a prospective, randomized, cross-over, and placebo-controlled study. Cats were assigned to receive an oral single dose of trazodone (50 mg) (TG), gabapentin (100 mg) (GG), trazodone (50 mg) and gabapentin (100 mg) (GTG), or placebo (PG).

Proximal tibial osteotomies for treating grade IV medial patellar luxation in two feline stifles.

Objectives: There is a lack of literature regarding the surgical management of high-grade patellar luxation in cats.

The Lasting Impact of Social Isolation: Behavioral Insights From Former Pet and Entertainer Chimpanzees in a Sanctuary in Spain.

Human fascination with chimpanzees has driven extensive research on the species, but also led to exploitation by private owners and entertainment industries. These animals often suffer species-specific inadequate conditions, which can result in the development and display of abnormal behaviors even after rescue. These behaviors highlight the importance for zoos and sanctuaries to actively prevent worsening the effects of previous inadequate treatment by providing apes with social and stimulating environments that support their recovery.

Ca3.2 T-type calcium channels contribute to CGRP- induced allodynia in a rodent model of experimental migraine.

Background: Migraine is a painful neurological syndrome characterized by attacks of throbbing headache, of moderate to severe intensity, which is associated with photo- and phono- sensitivity as well as nausea and vomiting. It affects about 15% of the world's population being 2-3 times more prevalent in females. The calcitonin gene-related peptide (CGRP) is a key mediator in the pathophysiology of migraine, and a significant advance in the field has been the development of anti-CGRP therapies.

Polyacrylamide Hydrogel Containing Starch and Sugarcane Bagasse Ash: Synthesis, Characterisation, and Application in Cement Pastes and Mortars.

Internal curing is a process based on the addition of materials that function as water reservoirs in cementitious media. Superabsorbent hydrogels are an alternative that can be used as an internal curing agent, as they have the ability to absorb and release water in a controlled manner. In the present work, superabsorbent hydrogels based on crosslinked polyacrylamide in the presence of starch and sugarcane bagasse ash (SCBA) were developed and applied to mortars as an internal curing agent.

Hydrogels Based on Polyacrylamide and Pectin Containing Rice Husk Ash: Preparation, Characterization and Application in Formulation of Cementitious Materials.

Superabsorbent polymers (PSAs) have been extensively studied to act as internal curing agents in cementitious materials, as they have the characteristic of absorbing and releasing water in a controlled manner, which can contribute to the hydration process of a cementitious medium during its consolidation. Thus, hydrogels consisting of polyacrylamide (PAAm), pectin (Pec) and rice husk ash (RHA) were synthesized to be applied in cementitious matrices. In addition, the PSAs were characterized by FTIR, SEM, and XRD.
