The combined effects of transcutaneous electrical stimulation (tES) of the spinal cord and affective sound stimulation on postural control were investigated to elucidate the involvement of spinal networks in the maintenance of vertical stability. Healthy volunteers (n = 27) underwent tES and sound stimulation separately and combined quasi-randomly. All participants were field-dependent; i.

Genomic Profiling in Glioma Patients to Explore Clinically Relevant Markers.

Gliomas are a heterogeneous group of brain tumors, among which the most aggressive subtype is glioblastoma, accounting for 60% of cases in adults. Available systemic treatment options are few and ineffective, so new approaches to therapies for glioblastoma are in high demand. In total, 131 patients with diffuse glioma were studied.

Transcutaneous spinal cord stimulation modulates quiet standing in healthy adults: stimulation site and cognitive style matter.

The study explored the effects of transcutaneous electrical spinal cord stimulation (tES) on postural control. Subjects were divided into field-dependent (FD) and field-independent (FI) groups according to their cognitive style. FD subjects use an exteroceptive afferent stream for spatial orientation, while FI subjects use an interoceptive stream.

Facial and systemic mucormycosis caused by in a goat: case report and literature review of fungal infections in goats.

An 8-y-old Pygora doe was presented to the University of California-Davis, Veterinary Medical Teaching Hospital because of non-healing facial swelling of 2-wk duration. The lesion grew despite medical treatment, causing discomfort masticating, little-to-no airflow from the right nasal passage, and led to euthanasia. On gross examination, a large facial mass with a draining tract through the skin and hard palate was identified.

Temporal integration of sound motion: Motion-onset response and perception.

The purpose of our study was to estimate the time interval required for integrating the acoustical changes related to sound motion using both psychophysical and EEG measures. Healthy listeners performed direction identification tasks under dichotic conditions in the delayed-motion paradigm. Minimal audible movement angle (MAMA) has been measured over the range of velocities from 60 to 360 deg/s.

Association between SARS-CoV-2 infections during pregnancy and preterm live birth.

We examined associations between mild or asymptomatic prenatal SARS-CoV-2 infection and preterm live birth in a prospective cohort study. During August 2020-October 2021, pregnant persons were followed with systematic surveillance for RT-PCR or serologically confirmed SARS-CoV-2 infection until pregnancy end. The association between prenatal SARS-CoV-2 infection and preterm birth was assessed using Cox proportional-hazards regression.

Assessment of Neurodevelopment in Infants With and Without Exposure to Asymptomatic or Mild Maternal SARS-CoV-2 Infection During Pregnancy.

Importance: Associations between prenatal SARS-CoV-2 exposure and neurodevelopmental outcomes have substantial public health relevance. A previous study found no association between prenatal SARS-CoV-2 infection and parent-reported infant neurodevelopmental outcomes, but standardized observational assessments are needed to confirm this finding.

Objective: To assess whether mild or asymptomatic maternal SARS-CoV-2 infection vs no infection during pregnancy is associated with infant neurodevelopmental differences at ages 5 to 11 months.

Evaluation of Serologic Cross-Reactivity Between Dengue Virus and SARS-CoV-2 in Patients with Acute Febrile Illness - United States and Puerto Rico, April 2020-March 2021.

The diagnosis of dengue disease, caused by the dengue virus (DENV) (a flavivirus), often requires serologic testing during acute and early convalescent phases of the disease. Some symptoms of DENV infection, such as nonspecific fever, are similar to those caused by infection with SARS-CoV-2, the virus that causes COVID-19. In studies with few COVID-19 cases, positive DENV immunoglobulin M (IgM) results were reported with various serologic tests, indicating possible cross-reactivity in these tests for DENV and SARS-CoV-2 infections (1,2).

Reserves for Reducing Mortality in Russia Due to the Efficiency of Health Care.

Approaches to assessing the role of health care in reducing mortality in Russia from the standpoint of controlling manageable causes are discussed. Based on the concept of avoidable mortality, trends in regional variability of mortality, the nosological and gender characteristics for the years 2000-2019 have been analyzed. The patterns revealed indicate the following: a significant contribution of medicine and health care to the decrease in the premature reduction in the life expectancy of the population, the expediency of developing a regional classification of the list of avoidable causes of mortality, and the decisive role of prevention and the improvement of the lifestyle of the population of young and middle ages in the past two decades against the background of a slow increase in the capacity of clinical medicine in the diagnostics and treatment of diseases.

Epidemiologic, Immunologic, and Virus Characteristics in Patients With Paired Severe Acute Respiratory Syndrome Coronavirus 2 Serology and Reverse-Transcription Polymerase Chain Reaction Testing.

Background: The natural history and clinical progression of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections can be better understood using combined serological and reverse-transcription polymerase chain reaction (RT-PCR) testing.

Methods: Nasopharyngeal swabs and serum were collected at a single time-point from patients at an urban, public hospital during August-November 2020 and tested for SARS-CoV-2 using RT-PCR, viral culture, and anti-spike pan-immunoglobulin antibody testing. Participant demographics and symptoms were collected through interview.

Synthesis of Perchlorinated Sulfonium Derivatives of -Decaborate Anion [2-BClSR] (R = -CH, -CH, -CH, -CH, -CH, -CH, CHPh, and -S(CH)).

A method for obtaining perchlorinated di-,-substituted derivatives of the -decaborate anion with various alkyl groups has been developed: [BClSR] (R= -CH, -CH, -CH, -CH, -CH, -CH, CHPh, and -S(CH)). The method is based on the preparation of the sulfonium-substituted anion [BHSR] by alkylation of the anion [BHSH] with bromoalkanes (-CHBr, -CHBr, -CHBr, -CHBr, -CHBr, -CHBr, PhCHBr, and BrCH(CH)CHBr) followed by the cluster chlorination with sulfuryl chloride SOCl in acetonitrile. The process proceeds until the hydrogen atoms in the boron cluster are completely replaced with chlorine and completes within 60 h.

Changes in Severe Acute Respiratory Syndrome Coronavirus 2 Seroprevalence Over Time in 10 Sites in the United States, March-August, 2020.

Background: Monitoring of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibody prevalence can complement case reporting to inform more accurate estimates of SARS-CoV-2 infection burden, but few studies have undertaken repeated sampling over time on a broad geographic scale.

Methods: We performed serologic testing on a convenience sample of residual serum obtained from persons of all ages, at 10 sites in the United States from 23 March through 14 August 2020, from routine clinical testing at commercial laboratories. We standardized our seroprevalence rates by age and sex, using census population projections and adjusted for laboratory assay performance.

Brain oscillations evoked by sound motion.

The present study investigates the event-related oscillations underlying the motion-onset response (MOR) evoked by sounds moving at different velocities. EEG was recorded for stationary sounds and for three patterns of sound motion produced by changes in interaural time differences. We explored the effect of motion velocity on the MOR potential, and also on the event-related spectral perturbation (ERSP) and inter-trial phase coherence (ITC) calculated from the time-frequency decomposition of EEG signals.

Comparison of Estimated Severe Acute Respiratory Syndrome Coronavirus 2 Seroprevalence Through Commercial Laboratory Residual Sera Testing and a Community Survey.

We compared severe acute respiratory syndrome coronavirus 2 seroprevalence estimated from commercial laboratory residual sera and a community household survey in metropolitan Atlanta during April and May 2020 and found these 2 estimates to be similar (4.94% vs 3.18%).

Decline in SARS-CoV-2 Antibodies After Mild Infection Among Frontline Health Care Personnel in a Multistate Hospital Network - 12 States, April-August 2020.

Most persons infected with SARS-CoV-2, the virus that causes coronavirus disease 2019 (COVID-19), develop virus-specific antibodies within several weeks, but antibody titers might decline over time. Understanding the timeline of antibody decline is important for interpreting SARS-CoV-2 serology results. Serum specimens were collected from a convenience sample of frontline health care personnel at 13 hospitals and tested for antibodies to SARS-CoV-2 during April 3-June 19, 2020, and again approximately 60 days later to assess this timeline.

F MRI of human lungs at 0.5 Tesla using octafluorocyclobutane.

Purpose: The aim of this study was to demonstrate the feasibility of fluorine-19 ( F) MRI of the human lungs using octafluorocyclobutane (OFCB, C F ). This gas has 8 magnetically equivalent fluorine nuclei and relatively long T and T (˜50 ms), which render it suitable as an MRI contrast agent. Previous experiments in small laboratory animals showed that OFCB could be successfully used as an alternative to the gases often used for F MRI (sulfur hexafluoride and perfluoropropane).

Lateralization of brain responses to auditory motion: A study using single-trial analysis.

The present study investigates hemispheric asymmetry of the ERPs and low-frequency oscillatory responses evoked in both hemispheres of the brain by the sound stimuli with delayed onset of motion. EEG was recorded for three patterns of sound motion produced by changes in interaural time differences. Event-related spectral perturbation (ERSP) and inter-trial phase coherence (ITC) were computed from the time-frequency decomposition of EEG signals.
