A pyroxene-based quantum magnet with multiple magnetization plateaus.

Pyroxenes (AMXO) consisting of infinite one-dimensional edge-sharing MO chains and bridging XO tetrahedra are fertile ground for finding quantum materials. Thus, here, we have studied calcium cobalt germanate (CaCoGeO) and calcium cobalt silicate (CaCoSiO) crystals in depth. Heat capacity data show that the spins in both compounds are dominantly Ising-like, even after being manipulated by high magnetic fields.

Implementation and validation of face de-identification (de-facing) in ADNI4.

Introduction: Recent technological advances have increased the risk that de-identified brain images could be re-identified from face imagery. The Alzheimer's Disease Neuroimaging Initiative (ADNI) is a leading source of publicly available de-identified brain imaging, who quickly acted to protect participants' privacy.

Methods: An independent expert committee evaluated 11 face-deidentification ("de-facing") methods and selected four for formal testing.

Multifaceted Intervention to Improve Graft Outcome Disparities in African American Kidney Transplants (MITIGAAT Study): Protocol for a Randomized Controlled Trial.

Background: The outcome disparities for African American recipients of kidney transplant is a public health issue that has plagued the field of transplant since its inception. Based on national data, African American recipients have nearly twice the risk of graft loss at 5 years after transplant, when compared with White recipients. Evidence demonstrates that medication nonadherence and high tacrolimus variability substantially impact graft outcomes and racial disparities, most notably late (>2 years) after the transplant.

Charting cortical-layer specific area boundaries using Gibbs' ringing attenuated T1w/T2w-FLAIR myelin MRI.

Cortical areas have traditionally been defined by their distinctive layer cyto- and/or myelo- architecture using postmortem histology. Recent studies have delineated many areas by measuring overall cortical myelin content and its spatial gradients using the T1w/T2w ratio MRI in living primates, including humans. While T1w/T2w studies of areal transitions might benefit from using the layer profile of this myelin-related contrast, a significant confound is Gibbs' ringing artefact, which produces signal fluctuations resembling cortical layers.

Urachal Adenocarcinoma: A Case Report of a Rare Tumor.

Urachal adenocarcinoma is a rare and aggressive bladder cancer involving the urachus, an embryological fibrous remnant of the allantois extending from the bladder to the umbilicus. Usually discovered in the advanced stages, this cancer can commonly present with a poor prognosis. We report a case of a 34-year-old male patient with an unremarkable medical history who presented to the emergency department with severe, sudden onset, sharp abdominal pain.

Associations of takeaway outlets with takeaway food consumption and adiposity: longitudinal analysis of the Fenland cohort.

Objective: This study builds on prior findings that link increased availability of takeaway food outlets in home, workplace, and commuting environments to greater takeaway consumption and adiposity. Using longitudinal data, we examine associations of takeaway availability at baseline with changes in consumption and adiposity between baseline and follow-up.

Methods: We analyzed data from the Fenland Study, with baseline data from 2005 to 2015 and follow-up from 2015 to 2020.

Effects of tenofovir disoproxil fumarate on intrahepatic viral burden and liver immune microenvironment in patients with chronic hepatitis B.

Background: The impact of nucleos(t)ide analogues on intrahepatic viral burden and immune microenvironment in patients with chronic hepatitis B (CHB) is not clear.

Objective: We aimed to characterise the effects of tenofovir disoproxil fumarate (TDF) on intrahepatic viral burden and the liver immune microenvironment in patients with CHB.

Design: Core liver biopsies were collected at baseline and year 3 from patients with CHB with minimally raised serum alanine aminotransferase in a double-blind placebo-controlled trial (NCT01522625).

Single cell spatial profiling of FFPE splenic tissue from a humanized mouse model of HIV infection.

Background: Latency remains a major obstacle to finding a cure for HIV despite the availability of antiretroviral therapy. Due to virus dormancy, limited biomarkers are available to identify latent HIV-infected cells. Profiling of individual HIV-infected cells is needed to explore potential latency biomarkers and to study the mechanisms of persistence that maintain the HIV reservoir.

A role for BYN-1/bystin in cellular uptake and clearance of residual bodies in the Caenorhabditis elegans germline.

GLH/Vasa/DDX4 helicases are core germ-granule proteins that promote germline development and fertility. A yeast-two-hybrid screen using Caenorhabditis elegans GLH-1 as bait identified BYN-1, the homolog of human bystin/BYSL. In humans, bystin promotes cell adhesion and invasion in gliomas, and, with its binding partner trophinin, triggers embryonic implantation into the uterine wall.

Cytogenetic bands and sharp peaks of Alu underlie large-scale segmental regulation of nuclear genome architecture.

Cytogenetic bands reflect genomic organization in large blocks of DNA with similar properties. Because banding patterns are invariant, this organization may often be assumed unimportant for genome regulation. Results here challenge that view.
