title: A new tetranuclear <i>N</i>-heterocyclic silver(I) complex as electrocatalyst for hydrogen evolution reaction

description: A new Ag(I) complex with the chemical composition, [Ag<sub>4</sub>(BBP)<sub>2</sub>(H<sub>2</sub>ebidc)]·4H<sub>2</sub>O (BBP = 1,3-bis(1H-benzimidazol-2-yl)propane, H<sub>6</sub>ebidc = 2,2’-(ethane-1,2-diyl)bis(1H-imidazole-4,5-dicarboxylic acid), was successfully synthesized by hydrothermal method and characterized by X-ray single crystal diffraction, elemental analysis, and infrared and ultraviolet spectroscopy. Crystallographic analysis revealed that the Ag(I) complex has a tetranuclear ring cluster structure, which are connected by π…π (<i>d</i> = 3.641 Å) interactions to form a one-dimensional supramolecular structure. The performance of electrocatalytic hydrogen evolution reaction (HER) of Ag(I) complex-modified carbon paste electrode (1-CPE) and bare electrode (sCPE) were investigated. In 0.5 M H<sub>2</sub>SO<sub>4</sub> with current density of 10 mA·cm<sup>−2</sup>, compared to sCPE, 1-CPE exhibited excellent electrocatalytic performance, with a positive shift of the overpotential (η<sub>10</sub>) by 478 mV and a reduction of the Tafel slope (<i>b</i>) by 95 mV·dec<sup>−1</sup>. The Nyquist plot of 1-CPE at −0.65 V has significantly smaller semicircle diameter in the high frequency region than sCPE, which indicated that it possessed less charge transfer resistance at the electrode surface as HER catalyst. The 1-CPE exhibited better electrocatalytic performance than the sCPE, presumably because the presence of Ag(I) complex improved the electrocatalytic performance of HER. This further confirms the potential value of Ag(I) complex as electrochemical materials.

title: A comparison of the grade of lightening between two agents, Whiteness Hp Maxx and Lase Peroxide Sensy, in patients attending the Dr. René Puig Bentz Dental Clinic at Universidad Nacional Pedro Henríquez Ureña.

description: Today, one of the characteristics of the ideal beauty stereotype for both men and women
is to have a “white” and bright smile, which is not easy to achieve
naturally, since the natural color of teeth is yellowish or opaque.
However, it has been possible to reduce the shade of tooth enamel through
simple, quick, and safe dental procedures.
This research was observational, descriptive, and cross-sectional. The sample was
selected for convenience, including 50 patients divided into two equal groups of
25 people, aged between 18 and 45 years. For data analysis, a database was
created in Microsoft Excel, from which the information was processed and presented in
graphs and statistical tables.
The results showed that both agents were effective, with grade 2 whitening predominating.
However, Lase Peroxide Sensy showed a slight advantage, with 20% of patients achieving grade 3,
compared to 16% of the group treated with Whiteness Hp Maxx. In
terms of tooth shades, shade A2 was the most common before treatment, while shade
A1 predominated after treatment, especially with Lase Peroxide Sensy (76%). The
age with the best results was 22 years, and females showed greater effectiveness (48%)
than males (24%). Sixty percent exposed eight teeth per arch, the criterion used to
define the number of teeth to be whitened. In terms of satisfaction, Lase Peroxide Sensy also stood out,
with 84% of patients completely satisfied vs. 72% for Whiteness Hp Maxx. It is concluded that
both agents are effective, but Lase Peroxide Sensy shows a slight superiority in
aesthetic results and patient satisfaction.
According to the results of this study, the null hypothesis (H0) is accepted, as it
confirms that the Lase Peroxide Sensy whitening agent offers a higher degree of whitening
than Whiteness Hp Maxx.

title: Macrogenomics-based analysis of rumen microbial composition and their metabolic pathways in yaks under different dietary concentrate-to-forage ratios

description: This study aimed to investigate the regulatory mechanisms underlying feed efficiency(FE) in yaks by analyzing the composition of rumen microorganisms and their major metabolic pathways using metagenomic analysis under different dietary concentrate-to-forage ratios. A total of 40 Qinghai Plateau yaks (8–9months old) with similar body weights (68.725±18.973kg)were randomly assigned to four treatment groups (n=10per group).The experimental groups were fed diets with concentrate-to-forage ratios of 80:20 (C80), 65:35 (C65), 50:50 (C50), and 35:65 (C35), respectively. The study included a 15-day pre-feeding period followed by a 105-day experimental feeding period.The results indicated that the total weight gain in the C65 group was significantly higher than in the C50 and C35 groups by 29.91% and 28.97%, respectively (P&lt;0.05). Additionally, the rumen pH in the C80 group was significantly higher than in the C65, C50, and C35 groups (P&lt;0.05). Metagenomic analysis revealed significant differences (P&lt;0.05) in bacterial and archaeal community compositions across groups. Bacteroidota, Bacillota, Prevotella, Bacteroides, and Ruminococcus were identified as the dominant bacterial taxa at the phylum and genus levels. Functional analysis of rumen microbial metabolism showed that in the C35 group, pathways related to starch and sucrose metabolism, as well as fructose and mannose metabolism, were significantly different from those in other groups. The C35 group exhibited higher activity in functional pathways related to starch and sucrose metabolism, fructose and mannose metabolism, cellulose degradation, and methanolysis. In contrast, the C80 group showed greater activity in cellulose degradation and methane metabolism. Notably, the C65 group exhibited the highest activity in sugar metabolism pathways (ko00500), facilitating starch and soluble sugar degradation and the rapid conversion of pyruvic acid into acetic acid and propionate. This enhanced energy utilization efficiency, suggesting a superior capacity for sugar metabolism.In conclusion, the dietary composition of the C65 group demonstrated the most favorable effects on growth performance, rumen fermentation optimization, and microbial balance maintenance.
