Neural signatures of default mode network subsystems in first-episode, drug-naive patients with major depressive disorder after 6-week thought induction psychotherapy treatment.

Evidence indicates that the default mode network (DMN) plays a crucial role in the neuropathology of major depressive disorder (MDD). However, the neural signatures of DMN subsystems in MDD after low resistance Thought Induction Psychotherapy (TIP) remain incompletely understood. We collected functional magnetic resonance imaging data from 20 first-episode, drug-naive MDD and 20 healthy controls (HCs).

Multi-omics study reveals different pathogenesis of the generation of skin lesions in SLE and IDLE patients.

Lupus erythematosus (LE) is a heterogeneous, antibody-mediated autoimmune disease. Isolate discoid LE (IDLE) and systematic LE (SLE) are traditionally regarded as the two ends of the spectrum, ranging from skin-limited damage to life-threatening multi-organ involvement. Both belong to LE, but IDLE and SLE differ in appearance of skin lesions, autoantibody panels, pathological changes, treatments, and immunopathogenesis.

Monolithically integrated triaxial high-performance micro accelerometers with position-independent pure axial stressed piezoresistive beams.

With the increasing demand for multidirectional vibration measurements, traditional triaxial accelerometers cannot achieve vibration measurements with high sensitivity, high natural frequency, and low cross-sensitivity simultaneously. Moreover, for piezoresistive accelerometers, achieving pure axial deformation of the piezoresistive beam can greatly improve performance, but it requires the piezoresistive beam to be located in a specific position, which inevitably makes the design more complex and limits the performance improvement. Here, a monolithically integrated triaxial high-performance accelerometer with pure axial stress piezoresistive beams was designed, fabricated, and tested.

Immune repertoire sequencing reveals an abnormal adaptive immune system in COVID-19 survivors.

Accumulating evidence suggests that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) impairs the adaptive immune system during acute infection. Still, it remains largely unclear whether the frequency and functions of T and B cells return to normal after the recovery of Coronavirus Disease 2019 (COVID-19). Here, we analyzed immune repertoires and SARS-CoV-2-specific neutralization antibodies in a prospective cohort of 40 COVID-19 survivors with a 6-month follow-up after hospital discharge.

Prevalence, characteristics, and consequences of verbal and physical violence against healthcare staff in Chinese hospitals during 2010-2020.

Objectives: This study investigated the characteristics of workplace violence (WPV) against Chinese healthcare staff and their casualties after severe physical violence (PV).

Methods: We scrutinized medical WPV incidents reported online and analyzed information on timing, location, violence, criminal incentives, and casualties following severe PV in China from 2010 to 2020.

Results: WPVs were mostly committed by young and middle-aged male family members of the patients, especially in the emergency department (49.

Systemic lupus erythematosus patients contain B-cell receptor repertoires sensitive to immunosuppressive drugs.

Immune repertoire (IR) during treatment may be a surrogate biomarker for disease response. Changes of the IR in systemic lupus erythematosus patients in response to immunosuppressive drugs were identified in ten SLE patients. Patients provided peripheral blood mononuclear cells at two time points for sequencing.

An Enhanced Expression Level of CXCR3 on Tfh-like Cells from Lupus Skin Lesions Rather Than Lupus Peripheral Blood.

Systemic lupus erythematosus (SLE) is a systemic autoimmune disease, and the etiopathogenesis is unclear. Follicular helper T (Tfh) cells have been reported as an important pathogenic cell type in SLE. CXCR3 was reported to be decreased on lupus peripheral CD4T cells.

Novel high-performance piezoresistive shock accelerometer for ultra-high-g measurement utilizing self-support sensing beams.

This study describes the design and implementation of a novel high-performance piezoresistive accelerometer for the measurement of shock acceleration of up to 100 000 g. The structure of the accelerometer sensing chip was implemented with piezoresistive self-support beams. The piezoresistors were made in piezoresistive sensing micro-beams, which were independent of support beams, to weaken the correlation between measuring sensitivity and resonant frequency.

Enhanced Sensitivity for Hydrogen Peroxide Detection: Polydiacetylene Vesicles with Phenylboronic Acid Head Group.

It was recently reported that, besides UV irradiated polymerization, polymerization of diacetylene compounds could also been initiated by radicals generated from enzyme catalyzed hydrogen peroxide (H2O2) decomposition. A new optical sensing method for H2O2 was proposed based on this phenomenon. However, the sensitivity of this method is relatively lower than existed ones.

Up-regulation of TGF-β via the activation of extracellular signal-regulated kinase 1 and 2 induced by prorenin in human renal mesangial cells.

Prorenin is thought to be an inactive precursor of renin. This study investigated whether human prorenin was capable of activating the (pro)renin receptors [(P)RRs], leading to the phosphorylation of extracellular signal-regulated kinase 1 and 2 (ERK1/2) in cultured human renal mesangial cells (HRMCs). HRMCs cultured in vitro were pretreated with an AT1 and AT2 blocker prior to stimulation by prorenin, PD98059 (an inhibitor of ERK1/2) and handle-region peptide (HRP).
