Article Synopsis
  • The study compared perceptual and cardiovascular responses during low-load resistance training with two types of blood flow restriction (BFR) methods: a non-elastic band (p-BFR) and a pneumatic cuff (t-BFR) among 16 trained men.
  • Participants engaged in similar upper-limb exercises under both conditions while their brachial blood pressure and heart rate were monitored, showing no significant differences in cardiovascular responses between the two methods.
  • The study concluded that when the width and material of the BFR devices are comparable, both methods yield similar levels of perceived exertion and pain during training.

The use of models capable of forecasting the production of photovoltaic (PV) energy is essential to guarantee the best possible integration of this energy source into traditional distribution grids. Long Short-Term Memory networks (LSTMs) are commonly used for this purpose, but their use may not be the better option due to their great computational complexity and slower inference and training time. Thus, in this work, we seek to evaluate the use of neural networks MLPs (Multilayer Perceptron), Recurrent Neural Networks (RNNs), and LSTMs, for the forecast of 5 min of photovoltaic energy production.

Background: There is a need to investigate relevant, acceptable and feasible approaches that promote participation in leisure-time physical activity for children with cerebral palsy (CP). The aim of this study is to assess the feasibility of a randomised controlled trial comparing a peer-group intervention focused on improving physical literacy (Sports Stars) with the combination of Sports Stars and a context-focused intervention (Pathways and Resources for Engagement and Participation, PREP) for ambulant children with CP in Brazil.

Methods: In this feasibility trial, 18 ambulant children (aged 6-12 years) with CP will be randomised into two groups (nine per group): (1) Sports Stars and (2) Sports Stars plus PREP.

Background: In the global effort to discover biomarkers for cancer prognosis, prediction tools have become essential resources. TCR (T cell receptor) repertoires contain important features that differentiate healthy controls from cancer patients or differentiate outcomes for patients being treated with different drugs. Considering, tools that can easily and quickly generate and identify important features out of TCR repertoire data and build accurate classifiers to predict future outcomes are essential.

(Crassulaceae) is used in traditional medicine for treating skin wounds. In our previous study, a topical gel containing aqueous leaf extract showed a preclinical anti-inflammatory effect in acute edema models. In continuation, the present study aims to evaluate the phytochemical content and the stability of a formulation in gel containing aqueous leaf extract and its healing properties and mechanism of action through an experimental model of induction of skin wounds in rats and assays.

Amphotericin B (AmB) is a potent antimicrobial agent used in clinical practice. Nevertheless, the mechanism of its aqueous instability remains not yet fully understood, especially the role that its aggregation state plays in this process. Therefore, the current study used an aqueous methanol media to evaluate the AmB instability as a function of pH-, organic solvent- and concentration-dependent ionization and aggregation.

In wells that operate by electrical submersible pump (ESP), the use of automation tools becomes essential in the interpretation of data. However, the fact that the wells work with automated systems does not guarantee the early diagnosis of operating conditions. The analysis of amperimetric charts is one of the ways to identify fail conditions.

Although new strategies for breast cancer treatment have yielded promising results, most drugs can lead to serious side effects when applied systemically. Doxorubicin (DOX), currently the most effective chemotherapeutic drug to treat breast cancer, is poorly selective towards tumor cells and treatment often leads to the development of drug resistance. Recent studies have indicated that several fatty acids (FAs) have beneficial effects on inhibiting tumorigenesis.

Background: High frequency (1-2 times per day) low-intensity blood flow restriction (BFR) training has been recommended as a prescription approach for short durations of time to maximize relevant physiological adaptations. However, some studies demonstrate negative physiological changes after short periods of high-frequency BFR training, including prolonged strength decline and muscle fiber atrophy.

Objectives: To provide a comprehensive overview of short-term, high-frequency blood flow restriction training, including main adaptations, myocellular stress, limitations in the literature, and future perspectives.

Background: Mechanical factors are primary complications that justify early removal of a peripherally inserted central catheter, and thrombotic catheter occlusion is the most critical mechanical complication associated with loss of device functionality. Studies have investigated these factors in adult patients, but findings are not directly applicable to newborns. Therefore, systematic reviews focusing on this population are necessary for consolidated evidence to aid clinical practice.
