Faster intervals, faster recoveries - intensified short VO running intervals are inferior to traditional long intervals in terms of time spent above 90% VO.

Introduction: High intensity interval training for improving maximal oxygen consumption (VO) is a fundamental component of specific preparation phases for middle- and long-distance runners. In this context, short intervals are very popular in practice. The aim of the present study was to determine whether increasing the intensity of short intervals around maximal aerobic speed (vVO), compared to traditional long interval runs, leads to a greater time spent above 90% VO.

Neuropsychological outcome of indoor rehabilitation in post-COVID-19 condition-results of the PoCoRe study.

Sexual and Gender Minority Adolescents' Preferences for HIV Pre-Exposure Prophylaxis Social Marketing Campaigns: Qualitative Preimplementation Study.

Background: Sexual and gender minority (SGM) adolescents in the United States are disproportionately affected by HIV. Pre-exposure prophylaxis (PrEP) is a highly effective biomedical HIV prevention method, but its awareness and uptake among SGM adolescents are low. There are no adolescent-centered PrEP social marketing campaigns in the United States that have the potential to increase awareness and interest in PrEP.

Emergence of antibiotic-specific phenotypes during prolonged treatment of mice.

A major challenge in tuberculosis (TB) therapeutics is that antibiotic exposure leads to changes in the physiology of (), which may enable the pathogen to withstand treatment. While antibiotic-treated has been evaluated in experiments it is unclear if and how long-term treatment with diverse antibiotics with varying treatment-shortening activity (sterilizing activity) affects physiologic processes differently. Here, we used SEARCH-TB, a pathogen-targeted RNA-sequencing platform, to characterize the transcriptome in the BALB/c high-dose aerosol infection mouse model following 4 weeks of treatment with three sterilizing and three non-sterilizing antibiotics.

Pretrained Deep Neural Network Kin-SiM for Single-Molecule FRET Trace Idealization.

Single-molecule fluorescence resonance energy transfer (smFRET) has emerged as a pivotal technique for probing biomolecular dynamics over time at nanometer scales. Quantitative analyses of smFRET time traces remain challenging due to confounding factors such as low signal-to-noise ratios, photophysical effects such as bleaching and blinking, and the complexity of modeling the underlying biomolecular states and kinetics. The dynamic distance information shaping the smFRET trace powerfully uncovers even transient conformational changes in single biomolecules both at or far from equilibrium, relying on trace idealization to identify specific interconverting states.

Vaccine Hesitancy and Its Epistemic Antecedents: A Meta-Analysis.

Although much attention has been given to vaccine hesitancy, there is still considerable ambiguity regarding its epistemological antecedents. The current meta-analysis addresses this theoretical and practical gap by focusing on the interplay between trust, belief in conspiracy theories, and COVID-19 vaccine hesitancy ( = 32), as well as key moderators such as the availability of the vaccine and the state and progress of the pandemic. Overall, results indicate that while both trust and beliefs in conspiracy theories are important correlates of vaccine hesitancy, considerable difference emerges when adopting a more granular approach that distinguishes between types of trust (government, public health organizations, science, and healthcare professionals/providers) and conspiracies (specific versus general).

Detection of Synchronous Foci of Infection using Positron Emission Tomography in Septic Patients Who Have a Periprosthetic Joint Infection.

Introduction: Periprosthetic joint infection (PJI) with sepsis is a life-threatening condition and identification of synchronous foci of infection is challenging. Positron emission tomography using F-fluorodeoxyglucose combined with computed tomography (F-FDG-PET/CT) is useful to detect PJI in elective, non-septic patients. We hypothesized that in patients who have PJI and concomitant sepsis requiring intensive care, F-FDG-PET/CT could accurately identify synchronous foci of infection.

smFRET-assisted RNA structure prediction.

Single-molecule Förster Resonance Energy Transfer (smFRET) is a powerful biophysical technique that utilizes the distance-dependent energy transfer between donor and acceptor dyes linked to individual molecules, providing insights into molecular conformational changes and interactions at the single-molecule level. Prior investigations leveraged smFRET to study the conformational dynamics of single truncated Ubc4 pre-mRNA molecules during splicing, yet these efforts did not prioritize structural modeling. In this study, we develop an smFRET-assisted RNA prediction method to predict the 2D and 3D structures of this pre-mRNA.

Foundation model for efficient biological discovery in single-molecule data.

Modern data-intensive techniques offer ever deeper insights into biology, but render the process of discovery increasingly complex. For example, exploiting the unique ability of single-molecule fluorescence microscopy (SMFM). to uncover rare but critical intermediates often demands manual inspection of time traces and iterative approaches that are difficult to systematize.

Ultrasensitive Amplification-Free Quantification of a Methyl CpG-Rich Cancer Biomarker by Single-Molecule Kinetic Fingerprinting.

The most well-studied epigenetic marker in humans is the 5-methyl modification of cytosine in DNA, which has great potential as a disease biomarker. Currently, quantification of DNA methylation relies heavily on bisulfite conversion followed by PCR amplification and NGS or microarray analysis. PCR is subject to potential bias in differential amplification of bisulfite-converted methylated versus unmethylated sequences.

Mechanistic model for epigenetic maintenance by methyl-CpG-binding domain proteins.

DNA methylation is a fundamental element of epigenetic regulation that is governed by the MBD protein superfamily, a group of "readers" that share a highly conserved methyl-CpG-binding domain (MBD) and mediate chromatin remodeler recruitment, transcription regulation, and coordination of DNA and histone modification. Previous work has characterized the binding affinity and sequence selectivity of MBD-containing proteins toward palindromes of 5-methylcytosine (5mC) containing 5mCpG dinucleotides, often referred to as single symmetrically methylated CpG sites. However, little is known about how MBD binding is influenced by the prototypical local clustering of methylated CpG sites and the presence of DNA structural motifs encountered, e.
