Background: The efficacy and safety of P2Y12 inhibitors (P2Y12i) with aspirin in patients with non-cardioembolic ischemic cerebrovascular events remains a topic of ongoing debate. Therefore, we conducted an updated meta-analysis to compare these drugs with aspirin alone.
Methods: We systematically searched PubMed, Embase, and Cochrane Central for randomized controlled trials (RCTs) comparing the two treatment regimens in patients with ischemic cerebrovascular events.

Orofacial pain is one of the most common causes of chronic pain leading to physical and cognitive disability. Several clinical and pre-clinical studies suggest that chronic pain results in cognitive impairment. However, there is a lack of meta-analyses examining the effects of orofacial pain models on behavioral learning and memory in rodents.

Objectives: This in vitro study aimed to investigate the toothbrushing wear on both enamel and dentin surfaces of reference and commercially available dentifrices.
Methods: Bovine enamel and dentin blocks were initially polished and embedded within a resin composite in square shapes (10×8×6 mm3). Employing toothbrushes equipped with nylon bristles, a toothbrushing machine was utilized, subjecting dentin specimens (n = 36) to 500 brush cycles and enamel samples to 5000 brush cycles (n = 36).

This paper presented the preparation, characterization, and adsorption properties of Brazil nut shell activated carbon for catechol removal from aqueous solutions. The equilibrium adsorption of catechol molecules on this activated was experimentally quantified at pH 6 and temperatures ranging from 25 to 55 °C, and at 25 °C and pH ranging from 6 to 10. These results were utilized to elucidate the role of surface functionalities through statistical physics calculations.

Lignocellulosic waste, like corn stover (CS), is widely produced and serves as a key feedstock for biofuels and biochemicals. Semi-continuous subcritical water hydrolysis (SWH) is an eco-friendly method that breaks down cellulose and hemicellulose bonds. To boost fermentable sugar (FS) yields, steam explosion (SE) pretreatment was tested on CS, achieving a cellulose content of 74.

In cells, the term "cellular aging" represents a collection of biological changes that can precede the proliferative senescence states. Cells more resistant to proliferative senescence, such as the ones found in the basal layer of the epidermis, may also exhibit these aging patterns. Therefore, cellular aging events could be induced by endogenous signals named here as cellular aging triggers (CATs) components.

Bipolar disorder (BD) is a central nervous system condition that is typified by fluctuations in mood, oscillating between depressive and manic, and/or hypomanic episodes. The objective of this study was to test the hypothesis that strength training may act as a potent protector against behavioral and neurochemical changes induced by BD. A strength training protocol was performed with adult male Wistar rats, and seven days following the conclusion of training, a single ouabain injection was administered.

Rice is considered to be moderately salt-tolerant during germination, development, and ripening stages, and environmentally sensitive during seedling and reproductive stages, which affects seedling emergence and growth, resulting in significant yield losses. Seed conditioning with chitosan has been employed as a useful tool in high-salinity environments with the aim of increasing crop productivity and quality, as well as promoting more sustainable agricultural practices. Therefore, this study aimed to examine the effect of seed conditioning with chitosan on seed germination and rice seedling growth under salinity stress.

Hypothyroidism is known to affect memory consolidation, and our prior research highlighted the potential of chrysin as a therapeutic agent to restore cognitive function. The present study aimed to investigate the action mechanism of chrysin on memory deficits in hypothyroid in C57BL/6 female mice. We assessed cognitive flexibility, declarative, working, and aversive memories while analyzing the BDNF/TrkB/AKT/Creb neuroplasticity signaling pathway and synaptic function in the hippocampus and prefrontal cortex.

Background: This meta-review aimed to synthesize the evidence of the effects of exercise on anxiety and depression symptoms amongst adults with cancer, and cancer-survivors, comparing effects sizes between meta-analysis.
Methods: Major databases were searched up to February 9, 2024 for meta-analyses evaluating the effects of exercise, using anxiety and/or depression scales. Effect size (ES) values were calculated as standardized differences in the means and expressed as the Standardized Mean Difference (SMD) with the 95% confidence interval (95%CI).

This study aimed to analyze yield components and maize yield cultivated at different population densities in management zones (MZs) delimited based on mapping the spatial variability of the soil's apparent electrical conductivity (ECa). The soil ECa was measured, and two MZs were subsequently delimited, one with low ECa and the other with high ECa. In each MZ, four maize sowing densities were tested: 60,000 (D1); 80,000 (D2); 100,000 (D3); and 140,000 (D4) seeds ha.

This study aimed to investigate the photobiological action of cocoa solution on a human fibroblast cell line (HFF-1) exposed to ultraviolet B (UVB) radiation. Three experimental models were utilized, where fibroblast cells were treated with different concentrations of cocoa as follows: 50; 100; 250; 500; 750; 1000 or 1500 µg/ml and concomitantly exposed to UVB 7 kJ/m for 10 min. The following parameters were examined 1) analysis of the pre-treatment action of cocoa; 2) investigation of the co-treatment activity of cocoa at the time of exposure; and 3) study the effect of cocoa in the post-treatment of the damage initiated by UVB.
