Influence of back muscle fatigue on dynamic lumbar spine stability and coordination variability of the thorax-pelvis during repetitive flexion-extension movements.

J Biomech 2022 Jan 20;133:110959. Epub 2022 Jan 20.

Department of Human Health and Nutritional Sciences, University of Guelph, Guelph, ON, Canada. Electronic address:

Previous work has identified that individuals adopt different dynamic lumbar spine stability responses when experiencing back muscle fatigue, and that the neuromuscular system adjusts multi-joint coordination in response to fatigue. Therefore, this study was designed to determine whether distinct differences in coordination and coordination variability would be observed for those who stabilize, destabilize, or demonstrate no change in dynamic stability when their back muscles are fatigued. Thirty participants completed two repetitive trunk flexion-extension trials (Rested, Fatigued) during which lumbar flexion-extension dynamic stability, thorax-pelvis movement coordination, and coupling angle variability (CAV) were assessed.

Braz Oral Res 2022 14;36:e012. Epub 2022 Jan 14.

Universidade Estadual de Campinas - Unicamp, Piracicaba Dental School, Oral Diagnosis Department, Semiology and Oral Pathology Areas, Piracicaba, SP, Brazil.

This study tested the hypothesis that head and neck radiotherapy (HNRT) impacts the immunoexpression of type I collagen, bone sialoprotein (BSP) and bone morphogenetic protein 4 (BMP4), thereby leading to micromorphological changes in the dentin-pulp complex (DPC), and promoting the onset and progression of radiation caries (RC). Twenty-two demineralized sections of carious teeth (a group of 11 irradiated teeth and a control group of 11 non-irradiated teeth) extracted from 19 head and neck cancer patients were analyzed by conventional optical microscopy and immunohistochemistry to investigate the micromorphology (cellular layer hierarchy, blood vessels, odontoblasts, fibroblasts, extracellular matrix, calcification, necrosis, reactionary dentin formation, and chronic inflammation), and the patterns of staining/immunolocalization of type I collagen, BSP and BMP4 in the dental pulp of irradiated and control samples. No significant differences attributable to the direct impact of radiotherapy were detected in DPC micromorphology between the groups. Read More

Why did the chicken not cross the road? Anthropogenic development influences the movement of a grassland bird.

Ecol Appl 2022 Jan 26:e2543. Epub 2022 Jan 26.

3 P.O. Box 392, El Coyote Ranch, Carrizo Springs, Texas, USA.

Movement and selection are inherently linked behaviors that form the foundation of a species' space-use patterns. Anthropogenic development in natural ecosystems can result in a variety of behavioral responses that can involve changes in either movement (speed or direction of travel) or selection (resources used) which in turn may cause population level consequences including loss landscape connectivity. Understanding how a species alters these different behaviors in response to human activity is essential for effective conservation. Read More

In silico deconjugation of glucuronide conjugates enhances tandem mass spectra library annotation of human samples.

Anal Bioanal Chem 2022 Jan 26. Epub 2022 Jan 26.

Institute of Legal Medicine and Core Facility Metabolomics, Medical University of Innsbruck, 6020, Innsbruck, Austria.

Mass spectral library annotation of liquid chromatography-high resolution tandem mass spectrometry (LC-HRMS/MS) data is a reliable approach for fast identification of organic contaminants and toxicants in complex environmental and biological matrices. While determining the exposure of humans or mammals, it is indispensable to include phase I and phase II metabolites (conjugates) along with the parent compounds, but often, tandem mass spectra for these are unavailable. In this study, we present and evaluate a strategy for annotating glucuronide conjugates in LC-HRMS/MS scans by applying a neutral loss search for detection, then truncating the spectra which we refer to as in silico deconjugation, and finally searching these against mass spectral libraries of the aglycones.

Adenovirus-α-defensin complexes induce NLRP3-associated maturation of human phagocytes via TLR4 engagement.

J Virol 2022 Jan 26:jvi0185021. Epub 2022 Jan 26.

Institut de Génétique Moléculaire de Montpellier, Université de Montpellier, CNRS, Montpellier, France.

Intramuscular delivery of human adenovirus (HAdV)-based vaccines leads to rapid recruitment of neutrophils, which then release antimicrobial peptides/proteins (AMPs). How these AMPs influence vaccine efficacy over the subsequent 24 h is poorly understood. In this study, we asked if human neutrophil protein 1 (HNP-1), an α-defensin that influences the direct and indirect innate immune responses to a range of pathogens, impacts the response of human phagocytes to three HAdV species/types (HAdV-C5, -D26, -B35).
