Evolutionary radiation of large‐bodied gorgonopsians from the lower Abrahamskraal formation of South Africa

open access: yesThe Anatomical Record, EarlyView.
Abstract The middle Permian represents a critical interval in therapsid evolution, when gorgonopsians emerged as some of the first specialized apex predators within terrestrial ecosystems. Despite their significance, the early diversification of Gorgonopsia in Gondwana remains poorly understood due to scarcity and fragmentary material.

Dos especies nuevas de hormigas de la tribu Attini de Costa Rica y México: Mycetosoritis vinsoni y Mycocepurus curvispinosus (Hymenoptera: Formicidae)

open access: yesRevista de Biología Tropical, 1998
Se describe Mycetosoritis vinsoni de Loma Barbudal, Guanacaste Prov. de Costa Rica, con base en el obrera holotipo. Es similar a M. hartmanni, pero se puede diferenciar gracias a que los pelos de los escapos son curvos y oprimidos (derechos y erectos en ...

Dietary Mannan‐Rich Fractions Attenuate Weaning Stress in Piglets via Modulating Gut Microbiota and TLR5/NF‐κB Signaling

open access: yesAnimal Research and One Health, EarlyView.
This study aimed to investigate the potential of a mannan‐rich fraction (MRF) as a dietary intervention to alleviate weaning stress in piglets. Our results revealed that MRF could alleviate weaning stress by modulating the gut microbiota and the TLR5/NF‐κB signaling pathway, offering a novel and sustainable alternative to antibiotic use in swine ...

Gamma suppression correlates with thalamic stimulation therapeutic response in intractable epilepsy. [PDF]

open access: yesEpilepsia
Abstract Objective In patients with drug‐resistant epilepsy who undergo anterior nucleus of the thalamus (ANT) deep brain stimulation (DBS), efficacy is assessed months after therapy initiation and clinicians have no guidance when choosing stimulation parameters due to the lack of real‐time biomarkers.

Arthroscopically Assisted Dynamic Medial Patellofemoral Ligament Graft Tensioning With Adaptive Length Using Double‐Bundle Technique

open access: yesArthroscopy Techniques, EarlyView.
Abstract This technical note describes a practical, anatomy‐based medial patellofemoral ligament reconstruction technique emphasizing individualized, dynamic graft tensioning and independent adjustment of patellar graft arms. By prioritizing femoral fixation first, guided by precise, dynamic anatomical landmarks and arthroscopic verification, the graft

Concurrent High Tibial Osteotomy, Anterior Cruciate Ligament Reconstruction, and Medial Meniscus Posterior Root Repair

open access: yesArthroscopy Techniques, EarlyView.
Abstract Medial meniscus posterior root tears and anterior cruciate ligament (ACL) injuries disrupt knee biomechanics and accelerate joint degeneration, particularly in the presence of varus malalignment. This technical note describes a combined surgical approach that integrates medial meniscus posterior root repair, ACL reconstruction, and high tibial

Natural history of liver disease in a large international cohort of children with Alagille syndrome: Results from the GALA study

open access: yesHepatology, EarlyView., 2022
Natural history of liver disease in a large international cohort of children with Alagille syndrome: Results from the GALA study. Abstract Background and Aims Alagille syndrome (ALGS) is a multisystem disorder, characterized by cholestasis. Existing outcome data are largely derived from tertiary centers, and real‐world data are lacking.

Visual Responsivity in Autism: Measuring Visual Responses in Autistic and Non‐Autistic Adults Using Psychophysics, fMRI, and EEG

open access: yesAutism Research, EarlyView.
ABSTRACT Autistic individuals frequently report heightened sensitivity to visual stimuli, often described as discomfort in environments with bright or flickering lights. These experiences are hypothesized to reflect underlying differences in sensory gain or neural hyperexcitability; however, findings across studies have yielded mixed results, likely ...
