Article Abstract
Purpose: The purpose of this study was to examine the effects of an additional set of exhaustive exercise before traditional hypertrophic training on quadriceps muscle performance in young men.
Methods: Subjects performed maximal dynamic strength (1RM), local muscular endurance (LME), and magnetic resonance imaging (MRI) tests before and after an 8-week hypertrophic training program using a knee extensor machine. After baseline testing, the subjects were divided into 3 groups: untrained control, traditional training (TR), and prior exhaustive training (PE). Both the TR and PE groups trained using the same training protocol (2 days week(-1); 3 sets of 8-12 repetitions at 75 % of 1RM); the only difference was that the PE group performed an additional set of exhaustive exercise at 20 % of 1RM before each training session.
Results: After 8 weeks, the PE group experienced a greater (P < 0.05) increase in 1RM, cross-sectional area, and LME than the TR group. Additionally, no changes (P > 0.05) in daily dietary intake were observed between groups.
Conclusion: These results suggest that the inclusion of a single set of exhaustive exercise at 20 % of 1RM before traditional hypertrophic training can be a suitable strategy for inducing additional beneficial effects on quadriceps strength, hypertrophy, and endurance in young men.

Personalized Federated Learning (pFL) has received extensive attentions, due to its ability to effectively process non-IID data distributed among different clients. However, most of the existing pFL methods focus on the collaboration between global and local models to enrich the personalization process, but ignoring a lot of valuable historical information, which represents the unique learning trajectory of each client. In this paper, we propose a pFL method called FedLFH, which introduces a tracking variable that allows each client to preserve historical information to facilitate personalization.

Most methodological Polygenic Risk Score (PRS)-related papers explain the laborious process of computing the PRS in great depth. Afterwards, as a last step, it is generally described that to test a possible association between a PRS and a trait of interest, an analysis through regression models (linear or logistic, depending on data type) should be carried out adjusting for covariates (e.g.

To this end, several parameters must be set during the processing of structural and functional data, and a variety of output features have been proposed. While emerging applications of the GSP framework have shown clear merits to reveal the neural underpinnings of brain disorders, behavioural facets or individuality, at present, the optimal parameter choices and feature types for an outcome of interest remain unknown.

Study Question: Can a prediction model classify IVF patients into distinct prognostic groups based on their expected yield of euploid blastocysts?
Summary Answer: Five distinct prognostic groups were identified, with chance of obtaining at least one euploid blastocyst ranging from <1% to 2% in very poor to ∼95% in very good prognosis groups.
What Is Known Already: Euploid blastocyst yield is a critical determinant of IVF success. While female age strongly influences embryo euploidy, other factors like ovarian reserve markers, partner age, and BMI may also contribute.

White wine lees are known to enhance the oxidative stability of white wine, but the complete set of compounds responsible for this property remain unidentified. Furthermore, due to matrix variability, the studies on the overall composition of lees are not exhaustive. In order to bring new insights, phytochemical constituents of 41 white wine lees samples were characterised, including tartaric acid, lipids, proteins, polysaccharides, polyphenols, and total sulfhydryl compounds.
