Unravelling the cleavage-rate relationship from both the experimental and theoretical standpoint: The instance of fluorite dissolution.

The phenomenon of solid dissolution into a solution constitutes a fundamental aspect in both natural and industrial contexts. Nevertheless, its intricate nature at the microscale poses a significant challenge for precise quantitative characterization at a foundational level. In this work, the influence across three specific cleavage planes, namely (100), (111), and (110) on the dissolution kinetics of fluorite in aqueous environments was examined from both experimental and theoretical standpoints.

In COVID-19 Health Messaging, Loss Framing Increases Anxiety with Little-to-No Concomitant Benefits: Experimental Evidence from 84 Countries.

The COVID-19 pandemic (and its aftermath) highlights a critical need to communicate health information effectively to the global public. Given that subtle differences in information framing can have meaningful effects on behavior, behavioral science research highlights a pressing question: Is it more effective to frame COVID-19 health messages in terms of potential losses (e.g.

Structure and Methylation of 35S rDNA in Allopolyploids (2 = 4 = 32, BBDD) and (2 = 6 = 48, AABBDD) and Their Parental Species Show Evidence of Nucleolar Dominance.

Transcriptional silencing of 35S rDNA loci inherited from one parental species is occurring relatively frequently in allopolyploids. However, molecular mechanisms by which it is selected for transcriptional silencing remain unclear. We applied NGS, silver staining and bisulfite sequencing to study the structure, expression and methylation landscape of 35S rDNA in two allopolyploids of common origin, allotetraploid (2 = 4 = 32, genome composition BBDD) and allohexaploid (2 = 6 = 48, AABBDD), and their genome donors, (2 = 16, AA), (2 = 16, BB) and (2 = 16, DD).

Transvaginally surgically treatment of early postpartum hemorrhage caused by lower uterine segment atony.

Objectives: Prove the success of transvaginal hemostatic procedures in treatment of the early postpartum hemorrhage caused by lower uterine segment atony.

Methods: We have conducted a retrospective, clinical study during a 10-year period (2010-2019) in our institution that is tertiary perinatal university center.

Results: This particular study enrolled total number of 29,543 deliveries with 215 cases of early postpartum hemorrhage (0.

A multi-country test of brief reappraisal interventions on emotions during the COVID-19 pandemic.

The COVID-19 pandemic has increased negative emotions and decreased positive emotions globally. Left unchecked, these emotional changes might have a wide array of adverse impacts. To reduce negative emotions and increase positive emotions, we tested the effectiveness of reappraisal, an emotion-regulation strategy that modifies how one thinks about a situation.

Cardiomyocyte Oga haploinsufficiency increases O-GlcNAcylation but hastens ventricular dysfunction following myocardial infarction.

Rationale: The beta-O-linkage of N-acetylglucosamine (i.e., O-GlcNAc) to proteins is a pro-adaptive response to cellular insults.

Cardiac mesenchymal cells from failing and nonfailing hearts limit ventricular dilation when administered late after infarction.

Although cell therapy-mediated cardiac repair offers promise for treatment/management of heart failure, lack of fundamental understanding of how cell therapy works limits its translational potential. In particular, whether reparative cells from failing hearts differ from cells derived from nonfailing hearts remains unexplored. Here, we assessed differences between cardiac mesenchymal cells (CMC) derived from failing (HF) versus nonfailing (Sham) hearts and whether the source of donor cells (i.

Negative pressure therapy with the ULTRAVAC instillation in the therapy of infected laparotomies with fascitis temporary results of a prospective randomized study.

Introduction: Negative pressure wound therapy is a healing modality utilizing continuous or intermittently applied vacuum to the wound bed. Nowadays is available a vacuum system supported by an automated instillation with volumetric control. It`s main therapeutic benefit is the dilution of the exudate, which reduces the viscosity and secures the «delicate» necrectomy.

Distribution of estrogens, 17beta-estradiol and estrone, in Canadian municipal wastewater treatment plants.

The distribution of female hormones, 17beta-estradiol and estrone, was determined in effluents of 18 selected municipal treatment plants across Canada. Replicate 24-h composite samples were collected from the influent and final effluent of each treatment plant, and the removal efficiency compared to the operational characteristics of the plants. In conventional activated sludge and lagoon treatment systems, the mean concentrations of 17beta-estradiol and estrone in influent were 15.

River evaluation using ecotoxicological and microbiological procedures.

One of the many problems researchers and managers face is to try and interpret data collected from various river studies. There is an underlying awareness of the incompleteness of most data bases due to a variety of problems outside of those concerning sample processing.In this study we have attempted, by using the battery of tests approach (12 tests) and the examination of different types of samples such as water, Milli-Q water extracted sediments, and organic solvent extracted sediments, to explore the implication of spacial and temporal sampling programmes.
