A detailed redescription of a skeletally immature ‘Redondasaurus’ suggests ontogenetic transformations in the taxon mirror phytosaurian morphological evolution

The Anatomical Record, EarlyView.
Abstract The study of morphological evolution is fundamentally tied to ontogeny, yet studies of these heterochronic processes in the fossil record are rare. Fossils belonging to an ontogenetic series are difficult to assign to an ontogenetic stage due to inconsistent proxies for skeletal ages, challenging to taxonomically assign due to morphological ...

Perception of pathogenic or beneficial bacteria and their evasion of host immunity: pattern recognition receptors in the frontline.

Frontiers in Plant Science, 2015
Plants are continuously monitoring the presence of microorganisms to establish an adapted response. Plants commonly use pattern recognition receptors (PRRs) to perceive microbe- or pathogen-associated molecular patterns (MAMPs/PAMPs) which are ...

Agent‐Based Computational Modeling of the Stochastic Dynamic Behavior of Actin Filaments Recapitulates the Homeostatic Cortical Array in Plant Epidermal Cells

Cytoskeleton, EarlyView.
ABSTRACT The homeostatic cortical actin array in plant cells plays important roles in fundamental processes, including intracellular transport, secretion, cell expansion, and cytoplasmic streaming. In response to diverse chemical and mechanical signals, the cortical array can remodel within minutes to assume new configurations or altered filament ...

Structure and evolution of the magnetochrome domains: no longer alone [PDF]

, 2014
Magnetotactic bacteria (MTB) can swim along Earth's magnetic field lines, thanks to the alignment of dedicated cytoplasmic organelles. These organelles, termed magnetosomes, are proteolipidic vesicles filled by a 35–120 nm crystal of either magnetite or ...

Microbial burden of periodontal diseases and its clinical application: The stage, grade, and furcation matter

Journal of Periodontology, EarlyView.
Abstract Background Periodontal diseases are associated with dysbiotic oral microbial communities, but clinically applicable measures that reflect microbial burden across disease severity and progression remain limited. This study aimed to assess the oral microbial burden of periodontal diseases by evaluating salivary and subgingival lipopolysaccharide

Effects of Methamphetamine on Testes Histopathology and Spermatogenesis Indices of Adult Male Rats [PDF]

Addiction and Health, 2017
Background: Methamphetamine (mAMP) as a recreational drug has devastating effects on the central nervous system (CNS). Several studies have shown that mAMP has inhibitory effects on oogenesis and spermatogenesis, and causes impaired fertility. This study

Innovation in Nucleotide-Binding Oligomerization-Like Receptor and Toll-Like Receptor Sensing Drives the Major Histocompatibility Complex-II Free Atlantic Cod Immune System

Frontiers in Immunology, 2020
The absence of MHC class II antigen presentation and multiple pathogen recognition receptors in the Atlantic cod has not impaired its immune response however how underlying mechanisms have adapted remains largely unknown.

Human Colitis‐on‐Chip Model Reveals Dual Roles of Butyrate in Epithelial and Macrophage Defense Against Candida albicans Tissue Invasion

Small, EarlyView.
This study establishes a human immunocompetent colitis‐on‐chip model that mimics inflamed gut mucosa and enables quantitative analysis of Candida albicans tissue invasion under DSS‐induced injury. It reveals that microbiota‐derived butyrate simultaneously stabilizes epithelial junctions and reprograms macrophages via HDAC/NLRP3‐dependent mechanisms ...
