Quorum Sensing Inhibits Type III‐A CRISPR‐Cas System Activity Through Repressing Positive Regulators SarA and ArcR in Staphylococcus Aureus

open access: yesAdvanced Science, EarlyView.
This study proposes a novel model illustrating how quorum sensing (QS) regulates the type III‐A CRISPR‐Cas system in Staphylococcus aureus. The QS regulator AgrA suppresses CRISPR‐Cas activity by downregulating the transcriptional regulators SarA and ArcR.

Molecular Chain Elongation Mechanism for n‐Caproate Biosynthesis by Megasphaera Hexanoica

open access: yesAdvanced Science, EarlyView.
The medium‐chain carboxylate‐producing microbe Megasphaera hexanoica is analyzed through genomics, transcriptomics, and metabolic engineering. The n‐caproate biosynthetic pathway is reconstructed in Escherichia coli, highlighting MhTHL as a key β‐ketothiolase. Structural analysis and mutagenesis reveal that MhTHL has a distinct substrate‐binding pocket,

Changes in muscle damage enzymes inactive overweight male students after exhausted aerobic and anaerobic exercise

open access: yesمجله دانشگاه علوم پزشکی بیرجند, 2017
Background and Aim: Since the intensity and duration of exercise and recovery time are one of the influencing factors on injuries and adaptations, the current study examined changes in muscle damage active in overweight male students after exhaustive ...

T2T Genomes Unveil Centromere Architecture and Adaptive Divergence in Large Yellow Croaker (Larimichthys crocea)

open access: yesAdvanced Science, EarlyView.
This study presents telomere‐to‐telomere genome assemblies for two populations of Larimichthys crocea. We identified centromere‐specific tandem repeats invaded by LTR/ERV1 retrotransposons, unique 5S rRNA enrichment patterns, and population‐specific structural variants. Comparative genomic analyses further reveal distinct adaptive mechanisms in the MYD

The Effect of High Intensity Aerobic and Anaerobic Training on the Memory of Healthy People

open access: yesAnnals of Applied Sport Science, 2017
Background. The evidence indicates that physical activity increases memory and ability to learn in human and animal. That is to say, the brain remarkably responds to exercise. Objectives.

THE RELATIONSHIP BETWEEN MUSCULOSKELETAL STRENGTH, PHYSIOLOGICAL CHARACTERISTICS, AND KNEE KINESTHESIA FOLLOWING FATIGUING EXERCISE [PDF]

open access: yes, 2012
Fatiguing exercise may result in impaired functional joint stability and increased risk of unintentional injury. While there are several musculoskeletal and physiological characteristics related to fatigue onset, their relationship with proprioceptive ...
