Correlation between Androgentic Alopecia and SARS-CoV-2 Omicron variant infection in China.

With the widespread prevalence of COVID-19, researches have suggested a potential link between androgens and COVID-19 outcomes. However, the relationship between COVID-19 and androgenetic alopecia (AGA)-a condition strongly influenced by androgens-remains controversial in existing studies. Notably, there is a lack of large-scale clinical studies, particularly concerning data on the Chinese population following infection with the Omicron variant.

The effect of the PERMA model-based positive psychological intervention on the quality of life of patients with breast cancer.

Objective: This research focused on exploring the impact of the PERMA model-based positive psychological intervention according to the negative emotions and quality of life of individuals with breast cancer.

Methods: A total of 82 individuals with breast cancer from our hospital were categorized into two groups randomly; the control group and the observation group (41 affected individuals each). The individuals in the control group underwent routine nursing intervention, while the ones in the observation group underwent PERMA nursing as per routine nursing intervention.

Active disturbance rejection control for non-minimum phase systems under plant reconstruction.

Active disturbance rejection control (ADRC) for non-minimum phase (NMP) systems is a challenging problem due to the conflict between stability and feedback tuning. The key point on this issue is to avoid heavy feedback tuning for robustness enhancement. We perform plant reconstruction to obtain an explicit expression of internal disturbance, such that it can be reduced by cascade compensation.

Multi-Scale Attention 3D Convolutional Network for Multimodal Gesture Recognition.

Gesture recognition is an important direction in computer vision research. Information from the hands is crucial in this task. However, current methods consistently achieve attention on hand regions based on estimated keypoints, which will significantly increase both time and complexity, and may lose position information of the hand due to wrong keypoint estimations.

Patients And Methods: A total of 193 telogen effluvium patients and 104 female androgenetic alopecia patients were included. We collected the test result of serum ferritin levels, compared with the results of 183 healthy subjects.

Innovative use of concentrated growth factors combined with corticosteroids to treat discoid lupus erythematosus alopecia: A case report.

Alopecia for patients with discoid lupus erythematosus can sometimes be a refractory condition, where mixed infiltrates of T lymphocytes and histiocytes leads to destruction of hair follicles, which might cause permanent scarring. Early diagnosis and timely treatment can achieve hair regeneration and prevent further disease progression. Concentrated growth factor, a novel autologous plasma extract, contains various growth factors that could promote tissue regeneration.

Unlabelled: The aim of this study was to investigate the pathological classifications, clinical features, and natural history of pediatric cardiac tumors to provide a basis for the selection of an appropriate therapeutic method. The medical records of in- or outpatients with cardiac tumors at four hospitals were classified to analyze various types of tumor growth locations, clinical manifestations, surgical indications, and long-term follow-up results. There were 166 patients, including 158 with primary cardiac tumors, six with metastatic cardiac tumors, and two with unclassified cardiac tumors.

Inhibitory effect of dexamethasone on expression of cysteine-rich 61 protein in airway epithelial cells of allergic mouse models.

In order to study whether cysteine-rich 61 protein (cyr61) is involved in the pathogenesis of asthma and its relation to airway inflammation, the effect of dexamethasone (Dxm) on the expression of cyr61 in the lung tissues of asthmatic mice was investigated. Forty BALB/c mice were divided into asthma group (n=15), control group (n=10) and Dxm group (n=15). The asthma group was sensitized and challenged by ovalbumin (OVA).

Interleukin (IL)-4 induces production of cytokine-induced neutrophil chemoattractants (CINCs) and intercellular adhesion molecule (ICAM)-1 in lungs of asthmatic rats.

The present study aimed to examine the effect of interleukin (IL)-4 on neutrophil chemotaxis in airway inflammation in asthmatic rats and the possible mechanism. Male Wistar rats were intranasally instilled with recombinant rat (rr) IL-4 (rrIL-4) at different doses [2, 4 or 8 μg/animal, dissolved in 200 μL normal saline (NS)] or rrIL-4 at 4 μg/animal (dissolved in 200 μL NS). NS (200 μL) and LPS (6 mg/kg/animal, dissolved in 200 μL NS) were intranasally given respectively in the negative and positive control groups.

Results: In fetal endometrium, Msi-1 positive cells were observed from the 12th week in epithelium, but the number of Msi-1 positive cells decreased with an increase in gestational age.

Interleukin(IL)-4 promotion of CXCL-8 gene transcription is mediated by ERK1/2 pathway in human pulmonary artery endothelial cells.

Interleukin-4 is central to allergic pulmonary inflammatory responses, but its contribution to airway neutrophilia remains controversial. The endothelium plays a critical role in regulating leukocyte recruitment and migration during inflammation. However, its response to IL-4 is reported to either increase or decrease the production of neutrophil chemotactic factors.

Spiking neural networks for cortical neuronal spike train decoding.

Recent investigation of cortical coding and computation indicates that temporal coding is probably a more biologically plausible scheme used by neurons than the rate coding used commonly in most published work. We propose and demonstrate in this letter that spiking neural networks (SNN), consisting of spiking neurons that propagate information by the timing of spikes, are a better alternative to the coding scheme based on spike frequency (histogram) alone. The SNN model analyzes cortical neural spike trains directly without losing temporal information for generating more reliable motor command for cortically controlled prosthetics.
