Ferroelectric Domain Wall Warp Memristor.

Domain walls are quasi-one-dimensional topological defects in ferroic materials, which can harbor emergent functionalities. In the case of ferroelectric domain wall (FEDW) devices, an exciting frontier has emerged: memristor-based information storage and processing approaches. Memristor solid-state FEDW devices presented thus far, however predominantly utilize a complex network of domain walls to achieve the desired regulation of density and charge state.

Background: Anthropometric measurements used to predict cardiovascular disease vary worldwide but are mostly derived from those of Caucasian ancestry. We sought to undertake such measurements in the little studied Bangladeshi population.

Methods: The MAGPIE (Multidimensional Approach of Genotype and Phenotype in Stroke Etiology) study is a Bangladeshi stroke case-control study that recruited nationwide between January 2022 and June 2024.

Synthesis, Crystal Structures, Antimicrobial Activity, and Acute Toxicity Evaluation of Chiral Zn(II) Schiff Base Complexes.

Four mononuclear bioefficient zinc coordination complexes [Zn(NN)](ClO) (-) involving chiral bidentate Schiff base ligands have been synthesized and characterized by IR, H, and C NMR spectroscopy and mass spectrometry. X-ray crystal structures of three of the zinc complexes revealed that the zinc metal ion is hexacoordinated, exhibiting a distorted octahedral geometry where both the nitrogen atoms (NN = pyridyl and imine) of imines are coordinated to the central zinc ion. The isolated zinc complexes were evaluated for their antimicrobial activity in vitro against , , and , displaying varying levels of growth inhibition.

Probe-Based Mechanical Data Storage on Polymers Made by Inverse Vulcanization.

Big data and artificial intelligence are driving increasing demand for high-density data storage. Probe-based data storage, such as mechanical storage using an atomic force microscope tip, is a potential solution with storage densities exceeding hard disks. However, the storage medium must be modifiable on the nanoscale.

Mendelian randomization assessing causal relationship between fibrinogen levels and ischemic stroke.

Objective: High fibrinogen levels are associated with an increased risk of ischaemic stroke (IS). We used mendelian randomisation (MR) to explore a potential causal relationship.

Materials And Methods: Data for assessing the relationship between gene variant, disease and biological levels needed for a MR approach was collected using a meta-analytical approach.

Multidimensional Approach of Genotype and Phenotype in Stroke Etiology: The MAGPIE Study.

Background And Aims: Stroke is a leading cause of mortality and morbidity in Bangladesh. It is estimated that genetic determinants account for around 40%-60% of its etiology, similar to environmental factors. This study aimed to provide a better understanding of the genetic, environmental, and clinical risk factors in stroke patients from Bangladesh.

Unlocking Osseointegration: Surface Engineering Strategies for Enhanced Dental Implant Integration.

Tooth loss is a prevalent problem faced by individuals of all ages across the globe. Various biomaterials, such as metals, bioceramics, polymers, composites of ceramics and polymers, etc., have been used for the manufacturing of dental implants.

Analytical Challenges in Novel Pentavalent Meningococcal Conjugate Vaccine (A, C, Y, W, X).

Multivalent meningococcal conjugate vaccines are a significant focus for the scientific community in light of the WHO's mission to defeat meningitidis by 2030. Well-known meningococcal vaccines such as MenAfriVac, Nimenrix, Menveo, and MenQuadfi are licensed in various parts of the world and have been successful. Recently, the World Health Organization (WHO) qualified MenFive (meningococcal A, C, Y, W, and X) conjugate vaccine, further enhancing the battery of vaccines against meningitis.

A Comparative Study Between Selective Nerve Root Blocks Versus Caudal Epidural Steroid Injection in the Management of Lumbar Radiculopathy.

Lumbar radiculopathy is one of the most common disorders encountered by a spine surgeon. The condition involves back pain, which may radiate to the lower limbs, and neurological symptoms, which involve a specific nerve root. Caudal epidural steroid injections (CESIs) and selective nerve root blocks (SNRBs) are two of the most common interventions, which are used to control the pain and neurological symptoms associated with chronic lumbar radiculopathy.

Transforming Spinal Surgery: The Life and Innovations of Dr. Paul Harrington.

This paper explores the life and contributions of Dr. Paul Harrington, a pioneering figure in spinal surgery, mainly known for his groundbreaking work in treating scoliosis. It delves into the development and impact of the Harrington rod, a revolutionary device that transformed the surgical management of spinal deformities.

Establishing Diagnostic Reference Levels for Single-Photon Emission Computed Tomography (SPECT) Imaging: A Preliminary Study in Indian Healthcare Settings.

Introduction In nuclear medicine, there is a critical need to balance the control and optimization of radiation doses to ensure patient safety while achieving high-quality diagnostic outcomes. However, diagnostic reference levels (DRLs) for nuclear medicine imaging studies have not been established in India. This study aims to fill this gap by establishing institutional DRLs and assessing radiation dose data specifically for Nuclear Medicine SPECT examinations.

Comparative Study between Proximal Femoral Nail Anti Rotation and Proximal Femoral Nail Anti Rotation Asian to Assessing Functional Outcome.

Introduction: Intertrochanteric fractures are one of the most common fractures around the pelvis and hip joint. Intrerotrochanteric fracture commonly occurs in elderly adult as a result of a simple domestic fall or slippage due to osteoporosis and young adult due to high-energy trauma. In 1990, 26% of all intertrochanteric fractures were reported in Asia, this figure is estimated to 32% in 2025 and 38% in 2050.

Exploration of the Sclerotinia sclerotiorum-Brassica pathosystem: advances and perspectives in omics studies.

The polyphagous phytopathogen Sclerotinia sclerotiorum causing Stem rot disease is a major biotic stress in Brassica, and affects the yield and quality in various crops of agricultural significance. It affects the crop at pre-maturity which causes a reduction in the seed yield and deteriorates the oil quality in rapeseeds and Indian mustard globally. The hemibiotrophic nature and long persistence in the soil as sclerotia have made this pathogen difficult to manage through conventional agronomical practices.

Real-Time Location Systems: Revolutionizing Porter Services for Improving Patient Care Efficiency.

Background: Transport porters (TPTs) are essentially involved in supporting hospital operations and maintaining high-quality patient care. The traditional porter management lacks transmission of temporal and spatial information of the porters thus affecting porter operations. In this work, we investigate the barriers in traditional porter management and the impact of a real-time location system (RTLS) in improving time and cost efficiency for porter operations.

Anomalous reverse mechanical polarization switching in negative piezoelectric CuInPS.

van der Waals ferroelectric CuInPS (CIPS) has drawn significant attention not only because of its unique properties but also owing to its technological potential for nanoelectronics. Mechanical polarization switching provides a new approach to modulating polarization states through flexoelectricity. This approach is particularly favourable for CIPS to avoid surface damage under an electric field due to the coupling between polarization switching and ionic motion.

IS Intra-masseteric Dexamethasone Better than Intra-deltoid Injection in Reducing Post-operative Sequelae Following Impacted Third Molar Surgery?: A Randomized Clinical Study.
