Vascular FLRT2 regulates venous-mediated angiogenic expansion and CNS barriergenesis.

Veins have emerged as the origin of all other endothelial cell subtypes needed to expand vascular networks during developmental and pathological neoangiogenesis. Here, we uncover the role of the angioneurin Fibronectin Leucine Rich Transmembrane protein (FLRT) 2 in central nervous system (CNS) vascular development in the mouse. Early postnatal FLRT2 deletion reveals specific defects in retinal veins, impacting endothelial cell proliferation, sprouting and polarity that result in reduced tip cells at the vascular front.

Performance of the EULAR Systemic sclerosis Impact of Disease (ScleroID) questionnaire as a patient-reported outcome measure for patients with diffuse systemic sclerosis.

Objective: Systemic sclerosis Impact of Disease (ScleroID) is the first comprehensive patient-reported outcome measure (PROM) specifically developed for systemic sclerosis (SSc). We investigated the performance of ScleroID in patients with diffuse cutaneous SSc (dcSSc), as a prerequisite for its use in randomised controlled trials (RCTs) testing potentially disease-modifying drugs.

Methods: All patients with dcSSc from the large, multicentric, ScleroID cohort were included.

FLASH Bragg-Peak Irradiation With a Therapeutic Carbon Ion Beam: First In Vivo Results.

Purpose: In recent years, ultra-high dose rate (UHDR) irradiation has emerged as a promising innovative approach to cancer treatment. Characteristic feature of this regimen, commonly referred to as FLASH effect, demonstrated primarily for electrons, photons, or protons, is the improved normal tissue sparing, whereas the tumor control is similar to the one of the conventional dose-rate (CDR) treatments. The FLASH mechanism is, however, unknown.

Impact of video instructions and additional hands-on instructions on the dental flossing performance - an observational study.

Objectives: This study aimed to evaluate the effectiveness of an instruction-video, with and without additional hands-on instruction, in teaching young adults proper flossing performance.

Materials And Methods: This randomised intervention and observational study included 94 participants, 24 (23; 25) years, receiving an instruction-video with (group 1) or without additional hands-on instruction (group 2). The flossing performance was assessed by videotaping before instruction (T1), after instruction and one week of practice (T2), as well as after two weeks of practice (T3).

Impact of Measured and Predicted Prosthesis-Patient Mismatch After Transcatheter Aortic Valve Replacement.

Background: Prosthesis-patient mismatch after transcatheter aortic valve replacement (TAVR) can be measured echocardiographically (measured prosthesis-patient mismatch [PPMm]) or predicted (predicted prosthesis-patient mismatch [PPMp]) using published effective orifice area (EOA) reference values. However, the clinical implications of PPM post-TAVR remain unclear.

Objectives: This study aimed to elucidate the prevalence of PPMm and PPMp post-TAVR and their impact on mortality in a large international cohort.

Prognostic relevance of exercise pulmonary hypertension: results of the multicentre PEX-NET Clinical Research Collaboration.

Background: Exercise pulmonary hypertension (PH) was defined by a mean pulmonary arterial pressure (mPAP)/cardiac output (CO) slope >3 mmHg·min·L between rest and exercise in the 2022 European Society of Cardiology/European Respiratory Society PH guidelines. However, large, multicentre studies on the prognostic relevance of exercise haemodynamics and its added value to resting haemodynamics are missing.

Patients And Methods: The PEX-NET (Pulmonary Haemodynamics during Exercise Network) registry enrolled patients who underwent clinically indicated right heart catheterisations both at rest and ergometer exercise from 23 PH centres worldwide.

Organ Tropism of Larval Stages in Infected African Giant Snails ().

is a metastrongyloid lungworm causing severe cardiovascular disease in domestic and wild animals. During its heteroxenous life cycle, requires obligate gastropod intermediate hosts. Little is known about larval organ tropism and development in gastropod intermediate hosts.

Non-Invasive Monitoring of Corticosterone Levels in Mouse Urine with Liquid Chromatography-Electrospray Ionization-Tandem Mass Spectrometry.

An innovative method for the quantification of corticosterone in the urine of C57BL/6J mice by liquid chromatography-electrospray ionization-tandem mass spectrometry was developed. Unconjugated and glucuronidated corticosterone was detected in the urine samples using enzymatic hydrolysis following liquid-liquid extraction. After optimization of the extraction protocol and LC-MS/MS parameters, we performed a validation study using a representative urine pool of C57BL/6J and Naval Medical Research Institute mice.

Kv3.3 Expression Enhanced by a Novel Variant in the Kozak Sequence of .

Pathogenic variants in , which encodes the voltage-gated potassium channel Kv3.3, are associated with spinocerebellar ataxia type 13. SCA13 is a neurodegenerative disease characterized by ataxia, dysarthria and oculomotor dysfunction, often in combination with other signs and symptoms such as cognitive impairment.

FgGET3, an ATPase of the GET Pathway, Is Important for the Development and Virulence of .

GET3 is an ATPase protein that plays a pivotal role in the guided entry of the tail-anchored (GET) pathway. The protein facilitates the targeting and inserting of tail-anchored (TA) proteins into the endoplasmic reticulum (ER) by interacting with a receptor protein complex on the ER. The role of GET3 in various biological processes has been established in yeast, plants, and mammals but not in filamentous fungi.

Effects of a Gastroscopic Procedure on Salivary Cortisol Release and Fecal Cortisol Metabolites in Young Racehorses.

In this study, gastroscopy was performed twice in 31 two-year-old Thoroughbred racehorses in training. Salivary cortisol (SC) and fecal cortisol metabolite (FCM) concentrations were determined to measure the stress impact. One gastroscopy was performed at the beginning and one six months later at the end of the horses' first training season.

Enhancement of Family-Centred Care Is Associated with a Reduction in Postmenstrual Age at Discharge in Preterm Infants.

Background/objectives: Long hospitalisation has been recognized as an independent risk factor for poor neurodevelopmental outcomes of preterm infants. Systematic training and early inclusion of parents in their preterm infant's care is a strategy to shorten the length of hospital stay. We implemented an enhanced stepwise family-centred care program and assessed its effects on postmenstrual age (PMA) at discharge and parental satisfaction.

Mycotoxin concentrations in rice are affected by chalkiness, grain shape, processing type, and grain origin.

Mycotoxins such as aflatoxins (AFs), fumonisins (FBs), zearalenone (ZEN), and deoxynivalenol (DON) pose a risk to public health due to their carcinogenic potency (AFs and FBs) and anti-nutritional effects. The hazards associated with mycotoxins are accentuated where food management practices, control, and regulatory systems from farm to plate are sub-optimal. Information on the frequency of these mycotoxins in rice commercialized in markets in sub-Sahara Africa (SSA) is limited.

Presence of Methicillin-Resistant Staphylococci and Carbapenemase-Positive Isolates on Surfaces in German Dog Daycare Facilities and Correlation with Cleaning Practices.

Many bacteria, including methicillin-resistant staphylococci and opportunistic pathogens such as (.) species, in particular members of the - () complex, are known to survive in environmental settings. This increases the risk of bacterial spreading and transmission to animals and humans, especially in institutions with a high animal population density.

Effects of the Dietary Fat Concentration and Fatty Acid Pattern on the Urine Composition, Apparent Nutrient Digestibility, and Selected Blood Values of Healthy Adult Cats.

: The dietary fat concentration and fatty acid profile can influence various aspects of the feline organism. This study examined their effects on the urine composition, apparent nutrient digestibility, and selected blood variables. : Ten healthy adult cats (46.

MOTH: Memory-Efficient On-the-Fly Tiling of Histological Image Annotations Using QuPath.

The emerging usage of digitalized histopathological images is leading to a novel possibility for data analysis. With the help of artificial intelligence algorithms, it is now possible to detect certain structures and morphological features on whole slide images automatically. This enables algorithms to count, measure, or evaluate those areas when trained properly.
