Equivalence of plasma and serum for clinical measurement of p-tau217: comparative analyses of four blood-based assays.

Background: Phosphorylated tau (p-tau) 217 is a promising blood biomarker for Alzheimer's disease (AD). However, most p-tau217 assays have been validated solely in ethylenediaminetetraacetic acid (EDTA) plasma, leaving the clinical applicability of serum p-tau217 largely unexplored despite serum being a preferred matrix in many clinical laboratories. To address this gap, we compared p-tau217 concentrations and diagnostic performances in matched plasma and serum samples using four research-use-only assays, including three from commercial sources i.

Comparison of Efficacy of Suprapatellar and Infrapatellar Approaches for Intramedullary Interlocking Nailing of Tibia in Patients With Tibial Fracture.

Introduction: Intramedullary interlocking nailing is a common surgical procedure for tibial fractures, enabling early patient mobilization. Traditionally, the infrapatellar approach has been used for intramedullary interlocking nailing of tibial fractures, but the suprapatellar approach is gaining attention for its potential benefits. This randomized controlled study aimed to compare the duration of the surgery, intra-operative blood loss, and fluoroscopy time between the suprapatellar and infrapatellar approaches.

Role for the PIP-binding protein myristoylated alanine-rich C-kinase substrate in vascular tissue: A novel therapeutic target for cardiovascular disease.

In vascular smooth muscle cells (VSMCs) and vascular endothelial cells (VECs), phosphatidylinositol 4,5-bisphosphate (PIP) acts as a substrate for phospholipase C (PLC)- and phosphoinositol 3-kinase (PI3K)-mediated signaling pathways and an unmodified ligand at ion channels and other macromolecules, which are key processes in the regulation of cell physiological and pathological phenotypes. It is envisaged that these distinct roles of PIP are achieved by PIP-binding proteins, which act as PIP buffers to produce discrete pools of PIP that permits targeted release within the cell. This review discusses evidence for the expression, cell distribution, and role of myristoylated alanine-rich C-kinase substrate (MARCKS), a PIP-binding protein, in cellular signaling and function of VSMCs.

Chemical activation of ABA signaling in grapevine through the iSB09 and AMF4 ABA receptor agonists enhances water use efficiency.

Grapevine (Vitis vinifera L.) is the world's third most valuable horticultural crop, and the current environmental scenario is massively shifting the grape cultivation landscape. The increase in heatwaves and drought episodes alter fruit ripening, compromise grape yield and vine survival, intensifying the pressure on using limited water resources.

The vacuolar K/H exchangers and calmodulin-like CML18 constitute a pH-sensing module that regulates K status in Arabidopsis.

Shifts in cytosolic pH have been recognized as key signaling events and mounting evidence supports the interdependence between H and Ca signaling in eukaryotic cells. Among the cellular pH-stats, K/H exchange at various membranes is paramount in plant cells. Vacuolar K/H exchangers of the NHX (Na,K/H exchanger) family control luminal pH and, together with K and H transporters at the plasma membrane, have been suggested to also regulate cytoplasmic pH.

Specific fibre areas in the femoral footprint of the posterior cruciate ligament act as a major contributor in resisting posterior tibial displacement: A biomechanical robotic investigation.

Purpose: Similar to the anterior cruciate ligament, the femoral footprint of the posterior cruciate ligament (PCL) is composed of different fibre areas, possibly having distinct biomechanical functions. The aim of this study was to determine the role of different fibre areas of the femoral footprint of the PCL in restraining posterior tibial translation (PTT).

Methods: A sequential cutting study was performed on eight fresh-frozen human knee specimens, utilizing a six-degrees-of-freedom robotic test setup.

Functional and Structural Analysis Reveals Distinct Biological Roles of Plant Synaptotagmins in Response to Environmental Stress.

Endoplasmic reticulum-plasma membrane contact sites (ER-PM CSs) are evolutionarily conserved membrane domains found in all eukaryotes, where the ER closely interfaces with the PM. This short distance is achieved in plants through the action of tether proteins such as synaptotagmins (SYTs). Arabidopsis comprises five SYT members (SYT1-SYT5), but whether they possess overlapping or distinct biological functions remains elusive.

Ohnut vs waitlist control for the self-management of endometriosis-associated deep dyspareunia: a pilot randomized controlled trial.

Background: Deep dyspareunia affects 50% of people with endometriosis. The Ohnut is a set of interlocking rings that fit over the penis/insertive object. One or more rings can be used to limit insertion depth and reduce deep dyspareunia.

Localizing motor entry points of adductor muscles of thigh for motor point procedures in the treatment of adductor spasticity.

Spasticity which is focal or segmental such as affecting a single muscle group or limb can be treated by chemical neurolysis or surgical denervation at the neurovascular hilus. This study determines the motor entry points (MEPs) of adductor muscles of the thigh in the adult Indian population and identifies precise anatomical landmarks for the successful performance motor point procedures for the relief of muscle spasticity. A total of 10 adult lower limbs were dissected, and nerve branches to adductor muscles were carefully exposed up to their MEP.

Crucial role for sensory nerves and Na/H exchanger inhibition in dapagliflozin- and empagliflozin-induced arterial relaxation.

Aims: Sodium/glucose transporter 2 (SGLT2 or SLC5A2) inhibitors lower blood glucose and are also approved treatments for heart failure independent of raised glucose. Various studies have showed that SGLT2 inhibitors relax arteries, but the underlying mechanisms are poorly understood and responses variable across arterial beds. We speculated that SGLT2 inhibitor-mediated arterial relaxation is dependent upon calcitonin gene-related peptide (CGRP) released from sensory nerves independent of glucose transport.
