Digital Dermatoglyphic Minutiae Patterns and Gross Motor Coordination Performance Among Undergraduate Students in a Nigerian Faculty of Basic Medical Sciences: A Descriptive Cross-Sectional Study

This descriptive cross-sectional study of 60 Nigerian undergraduate students found that while digital dermatoglyphic minutiae exhibited a consistent, quadrant-specific distribution pattern, there was no statistically significant association between these fingerprint characteristics and performance on a standardized rope-skipping task used to assess gross motor coordination.

Estimating VO2max in patients with obesity using machine learning: A retrospective observational cohort study

This retrospective study demonstrates that machine learning models, particularly Bayesian Ridge Regression and Automatic Relevance Determination, can effectively estimate VO2max in adults with obesity using accessible physiological inputs, offering a promising alternative to traditional testing despite a remaining accuracy gap compared to direct measurements.

The reset of aging counters in the germline and early embryo: a systematic review of centriole, telomere, mitochondrial, and epigenetic clocks across seven developmental transitions

This systematic review synthesizes quantitative evidence demonstrating that four distinct cellular aging counters—centrioles, telomeres, mitochondria, and the epigenome—undergo coordinated resets across seven developmental transitions from primordial germ cells to the blastocyst, converging on a single re-establishment boundary that suggests a unified germline rejuvenation mechanism.

Metataxonomic analysis of rectal samples of synanthropic bats from Montes Claros, Brazil

This study characterizes the gut microbiomes of eight synanthropic bat species in Montes Claros, Brazil, using 16S rRNA sequencing to identify predominant bacterial phyla, detect 34 potentially pathogenic genera, and report novel microbiota data for four species, thereby highlighting the importance of a One Health approach to bat-associated microbial risks.

Metabolic rewiring promotes metastasis while enhancing NK cell recognition

This study reveals that forcing cancer cells to switch to fatty acid oxidation via DCA treatment simultaneously promotes metastasis through EMT activation while enhancing their susceptibility to Natural Killer cell-mediated surveillance, identifying a metabolic vulnerability in metastatic cells.

Conserved Vibrio Repeats (VXRs) mediate horizontal transfer of superintegron-associated antibiotic resistance genes across Vibrio species

This study demonstrates that conserved Vibrio repeats (VXRs), primarily originating from the Cholera clade, facilitate the horizontal transfer of superintegron-associated antibiotic resistance genes across diverse Vibrio species, establishing these genomic elements as active reservoirs for the spread of antimicrobial resistance.
