Food Allergy-Induced Autism-Like Behavior is Associated with Gut Microbiota and Brain mTOR Signaling.

Purpose: Food allergy-induced autism-like behavior has been increasing for decades, but the causal drivers of this association are unclear. We sought to test the association of gut microbiota and mammalian/mechanistic target of rapamycin (mTOR) signaling with cow's milk allergy (CMA)-induced autism pathogenesis.

Methods: Mice were sensitized intragastrically with whey protein containing cholera toxin before sensitization on intraperitoneal injection with whey-containing alum, followed by intragastric allergen challenge to induce experimental CMA.

Mechanistic Studies of Gypenosides in Microglial State Transition and its Implications in Depression-Like Behaviors: Role of TLR4/MyD88/NF-κB Signaling.

Depression is a prevalent psychiatric disorder. Microglial state transition has been found in many neurological disorders including depression. Gypenosides (Gypenosides I-LXXVIII, Gps) are saponin extracts isolated from the traditional Chinese herb (Thunb.

Using a System Pharmacology Method to Search for the Potential Targets and Pathways of Yinqiaosan against COVID-19.

The first reported case of coronavirus disease 2019 (COVID-19) occurred in Wuhan, Hubei, China. Thereafter, it spread through China and worldwide in only a few months, reaching a pandemic level. It can cause severe respiratory illnesses such as pneumonia and lung failure.

Hyperbaric Oxygen Treatment Improves Hearing Level Attenuating TLR4/NF-κB Mediated Inflammation in Sudden Sensorineural Hearing Loss Patients.

Objective: Hyperbaric oxygen treatment (HBOT) has demonstrated efficacy in improving hearing levels of patients with idiopathic sudden sensorineural hearing loss (ISSHL); however, the underlying mechanisms are not well understood. HBOT alleviates the inflammatory response, which is mediated by Toll-like receptor (TLR) 4 and nuclear factor (NF)-κB. In this study we investigated whether HBOT attenuates inflammation in ISHHL patients alteration of TLR4 and NF-κB expression.

[Detection of common deletions and mutations causing α-thalassemia in Southeast Asians and Southern Chinese with denaturing high performance liquid chromatography].

Objective: To establish a comprehensive and simple assay using denaturing high performance liquid chromatography (DHPLC) for the diagnosis of most common mutations and deletions of α-thalassemia gene in Southeast Asians and Southern Chinese.

Methods: This assay has included a duplex polymerase chain reaction (PCR) followed by DHPLC analysis. An improved PCR was also performed followed by DHPLC analysis.

[Correlation of hippocampal acetylcholine and learning and study capability after anesthesia in senescent rats].

Objective: To investigate the general anesthetic's effect upon cholinergic system to examine whether the regional and progressive cholinergic changes may lead to postoperative cognitive dysfunction (POCD).

Method: A model of hippocampus microdialysis was established in aging rats (18 months old). The tissue levels of choline (Ch) and acetylcholine (Ach) were determined in hippocampus.

[Rapid diagnosis of Down's syndrome by multiplex real-time fluorescence relative quantitative PCR].

To establish a multiplex real-time fluorescence relative quantitative PCR method for diagnosis of Down's syndrome. The fragment from Down's syndrome critical region gene 3 (DSCR3) on chromosome 21 was used as the target gene, and the glyceraldehyde-3-phosphate dehydrogenase (GAPDH) gene on chromosome 12 was used as the control gene. The two genes were amplified in the same tube.

[High-level expression of phenylalanine ammonia-lyase in Lactococcus Lactis via synthesized sequence based on bias codons].

To construct a safer and more efficient gene engineering Lactococcus Lactis for expressing phenylalaine ammonia lyase (PAL) which will be benefit for PKU therapy, pal cDNA of Parsly and synthesized sequence based on Lactococcus Lactis bias codons were recombined into two Lactococcus Lactis NICE systems. The activities of the expressed PAL were detected, and the effect of Lactococcus Lactis bias codons on the expression of exterior protein was analyzed. The results showed that the expression level of PAL was increased by using Lactococcus Lactis bias codons in both Lactococcus Lactis NICE systems.

[The progressive study on gene therapy for hyperphenylalaninemia rats].

To construct a new high effective genetic engineering strain which can express active PAL enzyme in Lactococcus lactis (L.L), and acquire better effect on curing hyperphenylalaninemia rats, Firstly translational fusion vector and transcriptional fusion vector were constructed in E. coli MC1061, and then PAL cDNA was transformed into L.
