Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Biophysical approaches for studying viral entry

open access: yesFEBS Letters, EarlyView.
Viruses infect all living organisms and have been responsible for major epidemics and pandemics. Their ongoing evolutionary battle with host defenses creates a constant need for improved tools to study viral behavior. Advancing methods to probe viral attachment, fusion, and genome release deepen our understanding of how infections begin and support the

Similarities and differences in carotid artery, hemodynamic, and autonomic reactivity induced by mental stress or cold in adults: A randomized crossover study

open access: yesPhysiological Reports
The cold pressor test (CPT) is used to investigate cardiovascular and autonomic responses, while the Stroop color‐word test (Stroop) is also used for this purpose, although its vascular effects require further understanding.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Heartbeats and high scores: esports triggers cardiovascular and autonomic stress response

open access: yesFrontiers in Sports and Active Living
IntroductionGaming is often labeled as sedentary behavior. However, competitive gaming, also known as esports, involves significant cognitive demands and may induce stress.

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

open access: yesFEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Monitoring in the Physical Channels of Optical Access Networks

open access: yesProceedings of the International Conference on Applied Innovations in IT, 2023
This research concerns the issues of monitoring in the physical channels optical access networks. This is relevant because automated diagnostic and monitoring systems in passive optical networks (PONs) are not available at the moment. The authors discuss

Perceived stress, stress management, and vigorous physical activity among college students [PDF]

open access: yes, 2013
textObesity is a public health concern and obesity rates increase from adolescence to adulthood. Therefore, the period between 18-24, known as emerging adulthood, may be a crucial period in the development of obesity.

OXIDATIVE STRESS AND PHYSICAL ACTIVITY [PDF]

open access: yes, 2012
The cells continuously produce free radicals and reactive oxygen species as a part of metabolic processes. Increased aerobic metabolism during exercise is a potential source of oxidative stress.

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

open access: yesFEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.
