Geometric Morphometrics Reveal Body Shape Variation in Freshwater Shrimps of the Genus Macrobrachium Lacking a Mandibular Palp (Formerly Pseudopalaemon Sollaud, 1911) (Decapoda: Palaemonidae)

Acta Zoologica, EarlyView.
ABSTRACT Shape variation in the cephalothorax of Macrobrachium species without mandibular palp using geometric morphometrics was used as a tool to support species differentiation and propose new diagnostic characters for taxonomic identification.

Portrait of a Spectrum: Clinical and Genetic Characterization of a Large Cohort of Chromatinopathies—30 Years' Experience From a Third Level Center

Clinical Genetics, EarlyView.
Chromatinopathies (CP) are a growing group of rare genetic disorders characterized by cognitive deficits and growth abnormalities. This is the largest collection of CP to date, contributing to a deeper understanding of the landscape and diagnosis of these rare diseases, strongly improved by the use of large‐scale sequencing technologies.

Using miniaturized laboratory equipment and DNA barcoding to improve conservation genetics training and identify illegally traded species

Conservation Biology, EarlyView.
Abstract Illegal wildlife trade (IWT) is one of the largest global illegal activities, and it negatively affects biodiversity and sustainable development worldwide. DNA barcoding coupled with high‐throughput sequencing (i.e., metabarcoding) is useful in identifying taxa affected by IWT and has been used routinely for decades.

A Hanks‐type bacterial kinase, PknS, directly phosphorylates the alternative sigma factor EcfK to promote resistance to protist predation

The FEBS Journal, EarlyView.
The Xanthomonas citri Hanks‐type kinase PknS autophosphorylates and directly phosphorylates the alternative sigma factor EcfK at five residues. Besides the conserved residue T51 in the σ2 domain, phosphorylation of a residue in the linker between σ2 and σ4 is critical for EcfK activation by promoting its interaction with a positively charged pocket in ...

Immune complexes in chronic Chagas disease patients are formed by exovesicles from Trypanosoma cruzi carrying the conserved MASP N-terminal region [PDF]

, 2017
The exovesicles (EVs) are involved in pathologic host-parasite immune associations and have been recently used as biomarkers for diagnosis of infectious diseases.

Elucidating the Molecular Basis in a Cohort of Patients With Combined Bleeding Tendencies and Joint Hypermobility Manifestations

Haemophilia, EarlyView.
ABSTRACT Background In patients with unexplained bleeding and normal haemostatic parameters, heritable disorders of connective tissue (HDCT) may be an underlying cause due to vascular fragility, as observed in Ehlers–Danlos syndrome (EDS) or Marfan syndrome (MS). This study aims to investigate the molecular profile of patients with joint hypermobility (

β2-Chimaerin, a GTPase-Activating Protein for Rac1, Is a Novel Regulator of Hepatic Insulin Signaling and Glucose Metabolism

Molecules
Glucose homeostasis is a complex process regulated by multiple organs and hormones, with insulin playing a central role. Recent evidence underscores the role of small GTP-binding proteins, particularly Rac1, in regulating insulin secretion and glucose ...
