Evolving changes in cortical and subcortical excitability during movement preparation: A study of brain potentials and eye-blink reflexes during loud acoustic stimulation.

During preparation for action, the presentation of loud acoustic stimuli (LAS) can trigger movements at very short latencies in a phenomenon called the StartReact effect. It was initially proposed that a special, separate subcortical mechanism that bypasses slower cortical areas could be involved. We sought to examine the evidence for a separate mechanism against the alternative that responses to LAS can be explained by a combination of stimulus intensity effects and preparatory states.

Next-generation sequencing-based HLA typing reveals the association of HLA-B*46:01:01 and HLA-DRB1*09:01:02 alleles with carbamazepine-induced hypersensitivity reactions in Vietnamese patients with epilepsy.

Several studies have reported an association between certain human leukocyte antigen (HLA) alleles and carbamazepine (CBZ)-induced hypersensitivity reactions in patients with epilepsy. Here, the relationship between the clinical spectrum and the HLA allele profiles in patients with CBZ-induced hypersensitivity reactions was investigated using next-generation sequence (NGS) data obtained from 65 Vietnamese patients with epilepsy, including 33 with CBZ-tolerance and 32 patients with CBZ-hypersensitivity, in which only 8 with severe cutaneous adverse drug reactions and 24 were mild-hypersensitive patients. Three loci of HLA class I (HLA-A, -B, and -C) and two loci of HLA class II (HLA-DQA1 and -DRB1) were included in our analysis.

The mental health of Asian American adolescents and young adults amid the rise of anti-Asian racism.

Objectives: We describe the perceptions and experiences of anti-Asian racism and violence and depression severity prior to and during the COVID-19 pandemic among a sample of Asian American (AA) adolescents and young adults.

Methods: We used data from the Young Asian American Health Survey (YAAHS), an online-recruited sample of AA adolescents (ages 13-17) and young adults (ages 18-29 years) conducted during May 2021 to March 2022. We presented descriptive statistics examining the univariate distribution and bivariate relationships of depression severity, sociodemographic characteristics, and experiences and perceptions of anti-Asian violence.

A Study of Event-Related Potentials During Monaural and Bilateral Hearing in Single-Sided Deaf Cochlear Implant Users.

Objectives: Single-sided deafness (SSD) is characterized by a profoundly deaf ear and normal hearing in the contralateral ear. A cochlear implant (CI) is the only method to restore functional hearing in a profoundly deaf ear. In a previous study, we identified that the cortical processing of a CI signal differs from the normal-hearing ear (NHE) when directly compared using an auditory oddball paradigm consisting of pure tones.

Real-Time Monitoring of Biofilm Formation Using a Noninvasive Impedance-Based Method.

Biofilms are complex three-dimensional microbial communities that adhere to a variety of surfaces and interact with their surroundings. Because of the dynamic nature of biofilm formation, establishing a uniform technique for quantifying and monitoring biofilm volume, shape, and features in real-time is challenging. Herein, we describe a noninvasive electrochemical impedance approach for real-time monitoring of dental plaque-derived multispecies biofilm growth on a range of substrates.

[Severe cytomegalovirus-associated protein losing gastropathy in an immunocompetent adult].

Introduction: Clinical expression of cytomegalovirus (CMV) infection is numerous and depends on the immune status of the host. In immunocompromised patients, CMV disease corresponds to reactivation of the virus with tissue damage responsible for significant morbidity and mortality. In immunocompetent adults, primary CMV infection is usually asymptomatic but may rarely result in severe organ damage.

Global neuropathologic severity of Alzheimer's disease and locus coeruleus vulnerability influences plasma phosphorylated tau levels.

Background: Advances in ultrasensitive detection of phosphorylated tau (p-tau) in plasma has enabled the use of blood tests to measure Alzheimer's disease (AD) biomarker changes. Examination of postmortem brains of participants with antemortem plasma p-tau levels remains critical to understanding comorbid and AD-specific contribution to these biomarker changes.

Methods: We analyzed 35 population-based Mayo Clinic Study of Aging participants with plasma p-tau at threonine 181 and threonine 217 (p-tau181, p-tau217) available within 3 years of death.

Anodal-TDCS over Left-DLPFC Modulates Motor Cortex Excitability in Chronic Lower Back Pain.

Chronic pain is associated with abnormal cortical excitability and increased pain intensity. Research investigating the potential for transcranial direct current stimulation (tDCS) to modulate motor cortex excitability and reduce pain in individuals with chronic lower back pain (CLBP) yield mixed results. The present randomised, placebo-controlled study examined the impact of anodal-tDCS over left-dorsolateral prefrontal cortex (left-DLPFC) on motor cortex excitability and pain in those with CLBP.

A New Autosomal Smooth Muscle Cell Lineage Tracing and Gene Knockout Mouse Model-Brief Report.

Background: The promoter is extensively used as a smooth muscle cell (SMC) Cre-driver and is regarded as the most restrictive and specific promoter available to study SMCs. Unfortunately, in the existing mouse, the transgene was inserted on the Y chromosome precluding the study of female mice. Given the importance of including sex as a biological variable and that numerous SMC-based diseases have a sex-dependent bias, the field has been tremendously limited by the lack of a model to study both sexes.

TDP-43 pathology effect on volume and flortaucipir uptake in Alzheimer's disease.

Introduction: Alzheimer's disease (AD) patients ≥70 years show smaller medial temporal volumes despite less F-flortaucipir-positron emission tomography (PET) uptake than younger counterparts. We investigated whether TAR DNA-binding protein 43 (TDP-43) was contributing to this volume-uptake mismatch.

Methods: Seventy-seven participants with flortaucipir-PET and volumetric magnetic resonance imaging underwent postmortem AD and TDP-43 pathology assessments.

COVID-19 impacts, opportunities and challenges for wildlife farms in Binh Duong and Ba Ria Vung Tau, Vietnam.

The wildlife trade is a major cause of species loss and can trigger disease transmission. While the COVID-19 pandemic sparked public interest in eliminating the wildlife trade, a better understanding is needed of the economic repercussions of COVID-19 on those who rely on wildlife farming for their livelihoods. Using the case studies of Ba Ria Vung Tau and Binh Duong provinces in Vietnam - a country seen as Asia's wildlife trade hotspot - this paper explores COVID-19's impacts on wildlife farms and their owners.

Odd-even oddball task: Evaluating event-related potentials during word discrimination compared to speech-token and tone discrimination.

Tonal and speech token auditory oddball tasks have been commonly used to assess auditory processing in various populations; however, tasks using non-word sounds may fail to capture the higher-level ability to interpret and discriminate stimuli based on meaning, which are critical to language comprehension. As such, this study examines how neural signals associated with discrimination and evaluation-processes (P3b) from semantic stimuli compare with those elicited by tones and speech tokens. This study comprises of two experiments, both containing thirteen adults with normal hearing in both ears (PTA ≤ 20 dB HL).
