In vitro proteolysis mirrors intact muscle maturation in beef carcasses.

An in vitro assay was developed to study protease activity during the maturation of beef postmortem. Myofibrils were purified from the semitendinosus and used as a sentinel for assessing the activity of endogenous proteases in longissimus thoracis et lumborum (LTL) and the extensor carpi radialis (ER) over time postmortem in beef carcasses. Samples were collected from each muscle at 0, 1, 2, 7, and 14 d of aging and snap frozen.

Patterned glycopeptide-based supramolecular hydrogel promotes the alignment and contractility of iPSC-derived cardiomyocytes.

The functional restoration of a damaged cardiac tissue relies on a synchronized contractile capacity of exogenous and/or endogenous cardiomyocytes, which is challenging to achieve. Here, we explored the potential of the short glycopeptide diphenylalanine glucosamine-6-sulfate (FFGlcN6S) conjugated with an aromatic moiety, namely fluorenylmethoxycarbonyl (Fmoc), to enhance cardiac tissue regeneration. At physiological conditions, Fmoc-FFGlcN6S assembles into nanofibrous hydrated meshes, i.

Real-world data for marginal zone lymphoma patients in the French REALYSA cohort: The REALMA study.

Marginal Zone Lymphoma (MZL) comprises three subtypes: extranodal MZL (EMZL), splenic MZL (SMZL) and nodal MZL (NMZL). Since clinical trials have limited representativeness, there is a need for real-world data (RWD) evidence in MZL. Real-world data in Lymphoma and survival in Adults (REALYSA) is a prospective multicentric French cohort of newly diagnosed lymphoma patients.

Influence of variance component estimates on genomic predictions for growth and reproductive-related traits in Nellore cattle.

This study aimed to estimate variance components (VCs) for growth and reproductive traits in Nellore cattle using two relationship matrices (pedigree relationship A matrix and pedigree plus genomic relationship H matrix), and records collected before and after genomic selection (GS) implementation. The study also evaluated how genomic breeding values (GEBV) are affected by variance components and discarding old records. The analysed traits were weight at 120 days (W120), weight and scrotal circumference at 450 days (W450 and SC450, respectively).

Loop diuretic discontinuation in chronic heart failure patients: A retrospective study.

Introduction And Objectives: The use of loop diuretics is central in managing congestion in heart failure (HF), but their impact on prognosis remains unclear. In euvolemic patients, dose reduction is recommended, but there is no recommendation on their discontinuation. This study aims to assess the impact of loop diuretic discontinuation on the prognosis of outpatients with HF with reduced ejection fraction.

The ABRAFH and the visibility of homo and transparenthood families.

This is an interview conducted by Anna Paula Uziel, a professor at Rio de Janeiro State University, with Saulo Amorim, who was president of ABRAFH (Brazilian Association of Homotransafetive Families), about the history of the Association, its impact on the spread of these family configurations, and how it intersects with the interviewee's fatherhood story. The different characters who make up this story speak about the political moment in the country, the incorporation of transparenthood into ABRAFH. and how it is becoming a space of sociability and comfort for those who practice non-hegemonic parenting.

Pathogenic potential of an environmental Aspergillus fumigatus strain recovered from soil of Pygoscelis papua (Gentoo penguins) colony in Antarctica.

Aspergillus fumigatus is a common opportunistic pathogen in different animals, including birds such as penguins. For the first time, a fungal strain identified as A. fumigatus was isolated from soil in the nests of gentoo penguins, Pygoscelis papua, on Livingston Island, South Shetland Islands (maritime Antarctica).

Cardiopulmonary exercise testing in clinical practice: Principles, applications, and basic interpretation.

Cardiopulmonary exercise testing (CPET) provides a noninvasive and integrated assessment of the response of the respiratory, cardiovascular, and musculoskeletal systems to exercise. This information improves the diagnosis, risk stratification, and therapeutic management of several clinical conditions. Additionally, CPET is the gold standard test for cardiorespiratory fitness quantification and exercise prescription, both in patients with cardiopulmonary disease undergoing cardiac or pulmonary rehabilitation programs and in healthy individuals, such as high-level athletes.

20-year follow-up of rheumatic mitral stenosis patients after percutaneous mitral commissurotomy: invasive transmitral gradient differential as a predictor of events.

Percutaneous mitral valve commissurotomy (PMC) is a viable alternative to mitral valve (MV) surgery in the treatment of patients with rheumatic mitral stenosis (RMS). In this single-center retrospective study of consecutive patients with RMS submitted to PMC from 1991 to 2008, we analyzed clinical, echocardiographic, and hemodynamic data and events during follow-up (FUP) until December 2021. Major adverse cardiovascular events (MACE) were a combined endpoint of all-cause death, cardiovascular hospitalization, and MV re-intervention.

Genetic parameters for visual scores, growth and carcass traits in Nellore Cattle.

Growth and carcass traits are essential selection criteria for beef cattle breeding programs. However, it is necessary to combine these measurements with body composition traits to meet the demand of the consumer market. This study aimed to estimate the genetic parameters for visual scores, growth (pre and post-weaning weights), and carcass (rib eye area (REA), back and rump fat thickness) traits in Nellore cattle using Bayesian inference.

Screening of cardiac allograft vasculopathy in heart transplant patients with coronary computed tomography angiography.

Although coronary angiography (CA) is the gold standard for coronary allograft vasculopathy (CAV) screening, non-invasive modalities have arisen as potential alternatives, such as coronary computed tomography angiography (CCTA). CCTA also quantifies plaque burden, which may influence medical treatment. From January 2021 to April 2022, we prospectively included heart transplant recipients who performed CCTA as a first-line method for CAV detection in a single center.

Genetic correlation estimates between calving ease in primiparous cows and economically important traits in Nellore cattle.

This study aimed to estimate (co)variance components and genetic parameters for calving ease (CE) and their genetic correlations with growth, reproductive, carcass, and feed efficiency traits in Nellore cattle. Phenotypes for CE are scored in two categories: normal calving and assisted calving. The traits considered were probability of precocious calving, age at first calving, stayability, adjusted scrotal circumference at 365 days of age, accumulated cow productivity, age at puberty of males, gestation length, birth weight, adjusted weights at 210 and 450 days of age, adult cow weight, frame score, hip height, rib eye area, subcutaneous backfat thickness, rump fat thickness, intramuscular fat percentage, residual feed intake and dry matter intake.

Genotype-by-environment interactions for feed efficiency traits in Nellore cattle based on bi-trait reaction norm models.

Background: Selecting animals for feed efficiency directly impacts the profitability of the beef cattle industry, which contributes to minimizing the environmental footprint of beef production. Genetic and environmental factors influence animal feed efficiency, leading to phenotypic variability when exposed to different environmental conditions (i.e.

Fucoidan-Coated Silica Nanoparticles Promote the Differentiation of Human Mesenchymal Stem Cells into the Osteogenic Lineage.

Silica nanoparticles (SiNPs) are widely used in biomedical applications, such as cancer therapy/diagnosis or tissue engineering and regenerative medicine.

Tandem versus single haematopoietic stem cell transplant and BV maintenance in relapsed/refractory Hodgkin lymphoma: A matched cohort analysis from the LYSA.

Autologous hematopoietic stem cell transplant (ASCT) is the standard curative treatment for patients with high-risk relapsed/refractory Hodgkin lymphoma (R/R HL). The AETHERA study showed survival gain with Brentuximab Vedotin (BV) maintenance after ASCT in BV-naive patients, which was recently confirmed in the retrospective AMAHRELIS cohort, including a majority of BV-exposed patients. However, this approach has not been compared to intensive tandem auto/auto or auto/allo transplant strategies, which were used before BV approval.
