The observation criteria included shifting weight, claw conformation, and obvious disorders of the distal limb.

Marine sponge microbe provides insights into evolution and virulence of the tubercle bacillus.

Reconstructing the evolutionary origins of Mycobacterium tuberculosis, the causative agent of human tuberculosis, has helped identify bacterial factors that have led to the tubercle bacillus becoming such a formidable human pathogen. Here we report the discovery and detailed characterization of an exceedingly slow growing mycobacterium that is closely related to M. tuberculosis for which we have proposed the species name Mycobacterium spongiae sp.

A phase 3, randomized, double-blind, sham-controlled trial of SI-6603 (condoliase) in patients with radicular leg pain associated with lumbar disc herniation.

Background Context: SI-6603 (condoliase) is a chemonucleolytic agent approved in Japan in 2018 for the treatment of lumbar disc herniation (LDH) associated with radicular leg pain. Condoliase, a mucopolysaccharidase with high substrate specificity for glycosaminoglycans (GAGs), offers a unique mechanism of action through the degradation of GAGs in the nucleus pulposus. As LDH management is currently limited to conservative approaches and surgical intervention, condoliase could offer a less invasive treatment option than surgery for patients with LDH.

Study Design: We conducted a retrospective cohort study using vital statistics data from the Oregon Health Authority of all medical and surgical abortions between 2015 and 2023.

Results: Following the Dobbs decision, 14.

Macaque antibodies targeting Marburg virus glycoprotein induced by multivalent immunization.

Unlabelled: Marburg virus infection in humans is associated with case fatality rates that can reach up to 90%, but to date, there are no approved vaccines or monoclonal antibody (mAb) countermeasures. Here, we immunized Rhesus macaques with multivalent combinations of filovirus glycoprotein (GP) antigens belonging to Marburg, Sudan, and Ebola viruses to generate monospecific and cross-reactive antibody responses against them. From the animal that developed the highest titers of Marburg virus GP-specific neutralizing antibodies, we sorted single memory B cells using a heterologous Ravn virus GP probe and cloned and characterized a panel of 34 mAbs belonging to 28 unique lineages.

Hepatitis C Virus E1E2 Structure, Diversity, and Implications for Vaccine Development.

Hepatitis C virus (HCV) is a major medical health burden and the leading cause of chronic liver disease and cancer worldwide. More than 58 million people are chronically infected with HCV, with 1.5 million new infections occurring each year.

Differences between rural and urban residence in the detection and treatment of perinatal mood and anxiety disorders.

Background: Perinatal mood and anxiety disorders are common, serious complications of pregnancy. Disparities exist by race and income in the prevalence and treatment of these conditions, and overall treatment rates remain low. Outside of pregnancy, a small body of literature suggests that rural residency may contribute to higher rates of depression for those who identify as women.

Objectives: Evaluate the impact of the Dobbs vs Jackson decision on abortion care at an academic center in Oregon, a state with no legal restrictions on abortion.

Study Design: Electronic health records from patients who received an abortion at Oregon's largest tertiary hospital were utilized to compare the years before and after Dobbs.

Results: Monthly average abortions increased from 57.

Glycoengineered recombinant alpha1-antitrypsin results in comparable and activities to human plasma-derived protein.

Alpha-1-antitrypsin (A1AT) is a multifunctional, clinically important, high value therapeutic glycoprotein that can be used for the treatment of many diseases such as alpha-1-antitrypsin deficiency, diabetes, graft-versus-host-disease, cystic fibrosis and various viral infections. Currently, the only FDA-approved treatment for A1AT disorders is intravenous augmentation therapy with human plasma-derived A1AT. In addition to its limited supply, this approach poses a risk of infection transmission, since it uses therapeutic A1AT harvested from donors.

The rod synapse in aging wildtype and Dscaml1 mutant mice.

The retina is an intricately organized neural tissue built on cone and rod pathways for color and night vision. Genetic mutations that disrupt the proper function of the rod circuit contribute to blinding diseases including retinitis pigmentosa and congenital stationary night blindness (CSNB). Down Syndrome cell adhesion molecule like 1 (Dscaml1) is expressed by rods, rod bipolar cells (RBCs), and sub-populations of amacrine cells, and has been linked to a middle age onset of CSNB in humans.

Towards Improved Identification of Vertebral Fractures in Routine Computed Tomography (CT) Scans: Development and External Validation of a Machine Learning Algorithm.

Vertebral fractures (VFs) are the hallmark of osteoporosis, being one of the most frequent types of fragility fracture and an early sign of the disease. They are associated with significant morbidity and mortality. VFs are incidentally found in one out of five imaging studies, however, more than half of the VFs are not identified nor reported in patient computed tomography (CT) scans.
