Sub-cellular population imaging tools reveal stable apical dendrites in hippocampal area CA3.

Apical and basal dendrites of pyramidal neurons receive anatomically and functionally distinct inputs, implying compartment-level functional diversity during behavior. To test this, we imaged in vivo calcium signals from soma, apical dendrites, and basal dendrites in mouse hippocampal CA3 pyramidal neurons during head-fixed navigation. To capture compartment-specific population dynamics, we developed computational tools to automatically segment dendrites and extract accurate fluorescence traces from densely labeled neurons.

Biochemical mechanisms and molecular interactions of vitamins in cancer therapy.

Recently, the potential role of vitamins in cancer therapy has attracted considerable research attention. However, the reported findings are inconsistent, with limited information on the biochemical and molecular interactions of different vitamins in various cancer cells. Importantly, the presence of vitamin receptors in tumor cells suggests that vitamins play a significant role in the molecular and biochemical interactions in cancers.

Statin Use is Associated with Decreased Venous Thromboembolism Events Following Total Hip Arthroplasty: A Matched Retrospective Cohort Study.

Background: Despite advances in surgical techniques and postoperative prophylactic protocols, venous thromboembolism (VTE) events remain an important source of morbidity following total hip arthroplasty (THA). Prior research in cardiology and other surgical fields has suggested that statin medications may have a protective effect against VTE. Our study aimed to: 1) Assess if preoperative statin use was associated with decreased rates of VTE following THA, and 2) conduct a subgroup analysis of statin intensity and VTE events.

Benefits of Cilostazol's Effect on Vascular and Neuropathic Complications Caused by Diabetes.

Diabetes mellitus (DM) is a global health concern with a rising incidence, particularly in aging populations and those with a genetic predisposition. Over time, DM contributes to various complications, including nephropathy, retinopathy, peripheral arterial disease (PAD), and neuropathy. Among these, diabetic neuropathy and PAD stand out due to their high prevalence and significant impact on patients' quality of life.

Temperate grassland conversion to conifer forest destabilises mineral soil carbon stocks.

Tree-planting is increasingly presented as a cost-effective strategy to maximise ecosystem carbon (C) storage and thus mitigate climate change. Its success largely depends on the associated response of soil C stocks, where most terrestrial C is stored. Yet, we lack a precise understanding of how soil C stocks develop following tree planting, and particularly how it affects the form in which soil C is stored and its associated stability and resistance to climate change.

Fine-Tuned Expression of Evolutionarily Conserved Signaling Molecules in the Notochord.

The notochord is an axial structure required for the development of all chordate embryos, from sea squirts to humans. Over the course of more than half a billion years of chordate evolution, in addition to its structural function, the notochord has acquired increasingly relevant patterning roles for its surrounding tissues. This process has involved the co-option of signaling pathways and the acquisition of novel molecular mechanisms responsible for the precise timing and modalities of their deployment.

Delayed Tooth Development and the Impaired Differentiation of Stem/Progenitor Cells in Incisors from Type 2 Diabetes Mice.

Patients with diabetes mellitus (DM) have an increased risk of tooth decay caused by alterations in their tooth development and their oral environment, as well as a tendency to present with pulp infection due to compromised immune response. The present study analyzed the characteristic alterations in tooth development under DM conditions using incisors from type 2 diabetic mouse model (T2DM mice). In micro-CT analyses, T2DM mice showed delayed dentin and enamel formation.

Effects of E-Cigarette (e-cig) Aerosols on Mutagenesis in Selected Organs in a C57 (BigBlue) Mouse Model.

The objective of this study is to investigate the potential mutagenic effects of the exposure of mice to aerosols produced from the component liquids of an electronic nicotine delivery system (ENDS). The use of electronic cigarettes (e-cigs) and ENDSs has increased tremendously over the past two decades. From what we know to date, ENDSs contain much lower levels of known carcinogens than tobacco smoke.

Restoring small water bodies to improve lake and river water quality in China.

Climate change, population growth, and agricultural intensification are increasing nitrogen (N) inputs, while driving the loss of inland water bodies that filter excess N. However, the interplay between N inputs and water body dynamics, and its implications for water quality remain poorly understood. Analyzing data from 1995 to 2015 across China, here, we find a 71% reduction in the area of small (<10 m) water bodies (SWB), primarily in high-N-input agricultural regions.

Mitochondrial ROS modulate presynaptic plasticity in the drosophila neuromuscular junction.

The elevated emission of reactive oxygen species (ROS) from presynaptic mitochondria is well-documented in several inflammatory and neurodegenerative diseases. However, the potential role of mitochondrial ROS in presynaptic function and plasticity remains largely understudied beyond the context of disease. Here, we investigated this potential ROS role in presynaptic function and short-term plasticity by combining optogenetics, whole cell electrophysiological recordings, and live confocal imaging using a well-established protocol for induction and measurement of synaptic potentiation in Drosophila melanogaster neuromuscular junctions (NMJ).

A detailed inquiry of the differences between headphones and loudspeakers influences on dynamic postural task performance.

We examined the impact of auditory stimuli and their methods on a dynamic balance task performance. Twenty-four young adults wore an HTC Vive headset and dodged a virtual ball to the right or left based on its color (blue to the left, red to the right, and vice versa). We manipulated the environment by introducing congruent (auditory stimuli from the correct direction) or incongruent (auditory stimuli played randomly from either side) and comparing a multimodal (visual and congruent auditory stimuli) to unimodal (visual or auditory stimuli) presentation.

n-acetyl-l-cysteine stimulates bone healing by recovering the age-associated degenerative complications relative to osteoblastic Wntless ablation.

Dysregulated Wnt signaling causes age-related characteristics such as oxidative stress, stem cell senescence, and abnormal bone homeostasis. Here we explored whether supplemental n-acetyl-l-cysteine (NAC) recovers the age-associated complications relative to osteoblastic Wntless (Wls) ablation and examined the possible mechanisms therein. For this work, we administered Col2.

IFN-γ-producing T1 cells and dysfunctional regulatory T cells contribute to the pathogenesis of Sjögren's disease.

Sjögren's disease (SjD) is an autoimmune disorder characterized by progressive salivary and lacrimal gland dysfunction, inflammation, and destruction, as well as extraglandular manifestations. SjD is associated with autoreactive B and T cells, but its pathophysiology remains incompletely understood. Abnormalities in regulatory T (T) cells occur in several autoimmune diseases, but their role in SjD is ambiguous.

: Post-hepatectomy liver failure (PHLF) is a serious complication following hepatic resection for Klatskin tumors, significantly affecting patient prognosis. Identifying reliable preoperative and early postoperative predictors of PHLF can help optimize patient outcomes and guide surgical planning. : We conducted a retrospective review of 34 patients who underwent hemi-hepatectomy for extrahepatic cholangiocarcinoma at Kosin University Gospel Hospital between April 2019 and April 2024, and at Chonnam National University Hwasun Hospital between September 2017 and April 2024.

Chemomechanical regulation of growing tissues from a thermodynamically-consistent framework and its application to tumor spheroid growth.

It is widely recognized that reciprocal interactions between cells and their microenvironment, via mechanical forces and biochemical signaling pathways, regulate cell behaviors during normal development, homeostasis and disease progression such as cancer. However, it is still not well understood how complex patterns of tissue growth emerge. Here, we propose a framework for the chemomechanical regulation of growth based on thermodynamics of continua and growth-elasticity to predict growth patterns.
