Friends and foes: symbiotic and algicidal bacterial influence on blooms.

Harmful Algal Blooms (HABs) of the toxigenic dinoflagellate (KB) are pivotal in structuring the ecosystem of the Gulf of Mexico (GoM), decimating coastal ecology, local economies, and human health. Bacterial communities associated with toxigenic phytoplankton species play an important role in influencing toxin production in the laboratory, supplying essential factors to phytoplankton and even killing blooming species. However, our knowledge of the prevalence of these mechanisms during HAB events is limited, especially for KB blooms.

Endocytic tethers modulate unconventional GAPDH secretion.

Yeast cell walls contain both classically-secreted and unconventionally-secreted proteins. The latter class lacks the signal sequence for translocation into the ER, therefore these proteins are transported to the wall by uncharacterized mechanisms. One such protein is the glycolytic enzyme glyceraldehyde-3-phosphate dehydrogenase (GAPDH) which is abundant in the cytosol, but also found in the yeast cell wall where it is enzymatically active.

Intrahemispheric White Matter Asymmetries and Interhemispheric Connections Underlying the Lateralization of Language Production and Spatial Attention in Left-Handers.

Leftward language production and rightward spatial attention are salient features of functional organization in most humans, but their anatomical basis remains unclear. Interhemispheric connections and intrahemispheric white matter asymmetries have been proposed as important factors underlying functional lateralization. To investigate the role of white matter connectivity in functional lateralization, we first identified 96 left-handers using visual half field naming tasks.

Meta-analyses of the effects of high-intensity interval training in elite athletes-part I: mean effects on various performance measures.

Introduction: Meta-analysts have found that high-intensity interval training (HIIT) improves physical performance, but limited evidence exists regarding its effects on highly trained athletes, measures beyond maximum oxygen uptake ( O), and the moderating effects of different types of HIIT. In this study, we present meta-analyses of the effects of HIIT focusing on these deficits.

Methods: The effects of 6 types of HIIT and other moderators were derived from 34 studies involving highly trained endurance and elite athletes in percent units via log-transformation from separate meta-regression mixed models for sprint, time-trial, aerobic/anaerobic threshold, peak speed/power, repeated-sprint ability, O, and exercise economy.

Culturally Congruent Latino-Adapted Telemonitoring of Underrepresented Adults With Type 2 Diabetes: The CULTURA-DM2 Trial.

This study reports on the development and testing of a comprehensive diabetes telemonitoring program tailored to meet the needs of underserved Hispanic/Latino patients with diabetes. Individuals participating in the culturally tailored program had significantly better 6-month outcomes than those receiving comprehensive outpatient management for A1C, blood pressure, and diabetes self-efficacy, with no differences between groups in quality of life, medication adherence, emotional functioning, patient activation, or unscheduled physician visits. These findings suggest that culturally congruent diabetes telemonitoring may be effective for this underserved population.

Diabetes Centers' Participation in the T1D Exchange Quality Improvement Collaborative Advances Health Equity and Clinical Outcomes.

As the learning health network known as the T1D Exchange Quality Improvement Collaborative (T1DX-QI) has expanded on a significant scale to provide care for more than 120,000 people since its inception in 2016, assessing the quality improvement (QI) culture and monitoring clinical outcome improvements of participating centers has become vital to understanding the network's progress and success. Centers participating in the T1DX-QI complete regular QI culture self-assessments to quantify four evidence-based areas of culture: QI team structure, QI foundation, QI capacity, and QI success. This study builds on a previous baseline analysis to demonstrate self-reported improvements in T1DX-QI centers' QI culture from 2021 to 2022 and summarizes QI successes experienced by participating centers.

Associations between social behaviour and proinflammatory immune activation are modulated by age in a free-ranging primate population.

The effect of the social environment on the proinflammatory immune response may mediate the relationship between social environment and fitness but remains understudied outside captive animals and human populations. Age can also influence both immune function and social behaviour, and hence may modulate their relationships. This study investigates the role of social interactions in driving the concentrations of two urinary markers of proinflammatory immune activation, neopterin and soluble urokinase plasminogen activator receptor (suPAR), in a free-ranging population of rhesus macaques, .

Gadolinium-Free Cardiac MRI Myocardial Scar Detection by 4D Convolution Factorization.

Gadolinium-based contrast agents are commonly used in cardiac magnetic resonance (CMR) imaging to characterize myocardial scar tissue. Recent works using deep learning have shown the promise of contrast-free short-axis cine images to detect scars based on wall motion abnormalities (WMA) in ischemic patients. However, WMA can occur in patients without a scar.

Systemic Circulation in Advanced Heart Failure and Cardiogenic Shock: State-of-the-Art Review.

The integrative physiology of the left ventricle and systemic circulation is fundamental to our understanding of advanced heart failure and cardiogenic shock. In simplest terms, any increase in aortic stiffness increases the vascular afterload presented to the failing left ventricle. The net effect is increased myocardial oxygen demand and reduced coronary perfusion pressure, thereby further deteriorating contractile function.
