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 correlation between corona virus disease 2019 and alopecia areata: a literature review.

Corona virus disease 2019(COVID-19) is one of the most serious respiratory pandemic diseases threatening human health for centuries. Alopecia areata (AA) is a sudden patchy hair loss, an autoimmune disease, which seriously affects the image and mental health of patients. Evidence shows that the risk of autoimmune diseases significantly increases after COVID-19, and is positively correlated with the severity, with a significant increase in the risk of alopecia in those over 40 years old.

Properties of -O-Cu-O- Bridged Copper Phosphate-Based Thermal Insulation Materials.

P-O-H polycondensation -O-Cu-O- ion-bonded bridges were formed in copper phosphate thermal insulation materials by mixing Al(OH) dissolved in HPO with CuO filler and AlO, SiC, ZrC, and CrO as curing accelerators, alone or in combination. The effects of different additive combinations on the curing behavior and thermal stability of the copper phosphate thermal insulation material matrixes were compared using thermogravimetry/differential scanning calorimetry, X-ray diffractometry, and scanning electron microscopy. The copper phosphate materials exhibit good thermal stabilities and low thermal conductivities.

[Act of Arc siRNA via lentivirus on the memory consolidation of amygdala-kindled rats].

Objective: To explore the memory consolidation related role of gene Arc in amygdala-kindled rats.

Methods: A total of 60 male amygdala-kindled rats were divided equally into 3 groups: 0.9% sodium chloride injection, null vector lentivirus injection and silencing lentivirus injection.

[The effects of low-frequency electric stimulus on hippocampal of Effects of low-frequency electric stimulus on hippocampal of α5 subunit of extra synapse GABAA receptor in kainic acid-induced epilepsy rats].

Objective: To explore the effects of low-frequency electric stimulus (LFS) on hippocampal of α5 subunit of extrasynaptic GABAA receptor in kainic acid-induced epilepsy rats and explore the possible mechanism of LFS on hippocampus to treat epilepsy.

Methods: A total of 32 male Sprague-Dawley rats were divided randomly into 4 groups:epileptic, pseudo-surgery, LFS treatment and control. The expression of α5 subunit of extrasynaptic GABAA receptor and the association with the curative effects of LFS were evaluated by behavioristics, real-time fluorogenic quantitative polymerase chain reaction (PCR) and Western blot.

Relationship between the transmission of schistosomiasis japonica and the construction of the Three Gorge Reservoir.

Objective: To study the relationship between the changes of environment and the transmission of Schistosomiasis japonica after the construction of the Three Gorge Reservoir.

Methods: On the basis of the predictive data on changes of water level and sediment in the middle and lower reaches of the Yangtze River after the dam construction provided by the Yangtze River Committee on Water Conservancy, corresponding data were collected and analyzed. In order to understand the effects of changes of water level and sediment on Oncomelania hupensis, the intermediate host of Schistosoma japonicum, field surveys and ecologically intimated experiments were done.
