Introduction: Alterations in multiple subregions of the human prefrontal cortex (PFC) have been heavily implicated in psychiatric diseases. Moreover, emerging evidence suggests that circadian rhythms in gene expression are present across the brain, including in the PFC, and that these rhythms are altered in disease. However, investigation into the potential circadian mechanisms underlying these diseases in animal models must contend with the fact that the human PFC is highly evolved and specialized relative to that of rodents.

"The biggest challenge is there's never a routine": a qualitative study of the time burdens of cancer care at home.

Support Care Cancer

January 2025

Division of Hematology, Oncology, and Transplantation, University of Minnesota, 516 Delaware Street SE, MMC 480, PWB 14-100, Minneapolis, MN, 55455, USA.

Purpose: As cancer care is increasingly delivered in the home, more tasks and responsibilities fall on patients and their informal care partners. These time costs can present significant mental, physical, and financial burdens, and are undercounted in current measures of time toxicity that only consider care received in formal healthcare settings.

Methods: Semi-structured qualitative interviews were conducted with patients with gastrointestinal cancer and informal care partners at a single tertiary cancer center between March and October 2023.

Fluid secretion and luminal pressure control lateral branching morphogenesis in the embryonic avian lung.

Dev Biol

January 2025

Department of Bioengineering, University of Texas at Dallas, Richardson, TX; Department of Biomedical Engineering, UT Southwestern Medical Center, Dallas, TX. Electronic address:

During lung development, the embryonic airway originates as a wishbone-shaped epithelial tube, which undergoes a series of branching events to build the bronchial tree. This process depends crucially on cell proliferation and is thought to involve distinct branching modes: lateral branching, wherein daughter branches emerge along the length of a parent branch, and bifurcations, wherein the tip of a parent branch splits to form two new daughter branches. The developing airway is fluid-filled, and previous studies have shown that altered luminal pressure can influence rates of branching morphogenesis.

Computationally designed 29-residue peptides yield tetra-α-helical bundles with symmetry. The "bundlemers" can be bifunctionally linked via thiol-maleimide cross-links at their N-termini, yielding supramolecular polymers with unusually large, micrometer-scale persistence lengths. To provide a molecularly resolved understanding of these systems, all-atom molecular modeling and simulations of linked bundlemers in explicit solvent are presented.

Recurrent events modeling based on a reflected Brownian motion with application to hypoglycemia.

Biostatistics

December 2024

Department of Statistics, University of Connecticut, 215 Glenbrook Road Unit 4120, Storrs, CT 06269, United States.

Patients with type 2 diabetes need to closely monitor blood sugar levels as their routine diabetes self-management. Although many treatment agents aim to tightly control blood sugar, hypoglycemia often stands as an adverse event. In practice, patients can observe hypoglycemic events more easily than hyperglycemic events due to the perception of neurogenic symptoms.

Trans-active response DNA-binding protein-43 (TDP-43) is the major pathological protein in motor neuron disease and TDP-43 pathology has been described in the brains of up to 50% of patients with Alzheimer disease (AD). Hippocampal sclerosis of aging (HS-A), an age-related neuropathology characterized by severe neuronal loss and gliosis in CA1 and/or subiculum, is found in ∼80% of cases that are positive for phosphorylated TDP-43. HS-A is seen as a co-pathology in cases with AD, limbic-predominant age-related TDP-43 encephalopathy neuropathologic changes (LATE-NC), and frontotemporal degeneration.

Aging has a significant impact on brain structure, demonstrated by numerous MRI studies using diffusion tensor imaging (DTI). While these studies reveal changes in fractional anisotropy (FA) across different brain regions, they tend to focus on white matter tracts and cognitive regions, often overlooking gray matter and motor areas. Additionally, traditional DTI metrics can be affected by partial volume effects.

Background: Marek's disease (MD) is a pathology affecting chickens caused by Marek's disease virus (MDV), an acute transforming alphaherpesvirus of the genus . MD is characterized by paralysis, immune suppression, and the rapid formation of T-cell (primarily CD4+) lymphomas. Over the last 50 years, losses due to MDV infection have been controlled worldwide through vaccination; however, these live-attenuated vaccines are non-sterilizing and potentially contributed to the virulence evolution of MDV field strains.
