Investigation on the mechanical properties of Bacillus subtilis self-healing concrete.

In the process of research and development of self-healing concrete, it is observed that there are three main factors controlling the self-healing effect of concrete: first, the bacteria with repair ability and strong vitality; Second, the carrying capacity of the carrier and the matching degree with concrete; The third is the concentration of bacteria. This paper focuses on the mechanical properties of Bacillus subtilis self-healing concrete with sisal fiber, PVA, and expanded perlite as the carrier. To better study the mechanical properties of self-healing concrete caused by the carrier, the experiment adopts the design parameters of C30 concrete and conducts experiments on compressive resistance, flexural resistance, freeze-thaw cycle, and sulfate corrosion resistance to analyze the influence of different carriers on the mechanical properties of self-healing concrete, and obtains the best carrier.

Global H. pylori recurrence, recrudescence, and re-infection status after successful eradication in pediatric patients: a systematic review and meta-analysis.

Background: Little information is available regarding global H. pylori recurrence, recrudescence, and re-infection in pediatric patients after successful eradication, nor are their influencing factors clear. We conducted a systematic review and meta-analysis to determine global H.

LncRNA PSR Regulates Vascular Remodeling Through Encoding a Novel Protein Arteridin.

Rationale: Vascular smooth muscle cells (VSMCs) phenotype switch from contractile to proliferative phenotype is a pathological hallmark in various cardiovascular diseases. Recently, a subset of long noncoding RNAs was identified to produce functional polypeptides. However, the functional impact and regulatory mechanisms of long noncoding RNAs in VSMCs phenotype switching remain to be fully elucidated.

Circular RNA circEsyt2 regulates vascular smooth muscle cell remodeling via splicing regulation.

Circular RNAs (circRNAs) have been recently recognized as playing a role in the pathogenesis of vascular remodeling-related diseases by modulating the functions of miRNAs. However, the interplay between circRNAs and proteins during vascular remodeling remains poorly understood. Here, we investigated a previously identified circRNA, circEsyt2, whose expression is known to be upregulated during vascular remodeling.

Protective impacts of circular RNA VMA21 on lipopolysaccharide-engendered WI-38 cells injury via mediating microRNA-142-3p.

CircRNA derived from vacuolar ATPase assembly factor (circVMA21) is a newly-researched circRNA, which is reported to adjust the degeneration of intervertebral disc. But, function of circVMA21 in infantile pneumonia is yet to be explored. The research surveyed the role of circVMA21 in lipopolysaccharide (LPS)-caused WI-38 cell inflammatory injury.

Expression of DACT1 in children with asthma and its regulation mechanism.

The aim of the present study was to detect DACT1 expression levels in the lungs of children with asthma, and to investigate its role and molecular mechanisms in regulating the expression of inflammatory factors in RAW264.7 cells. DACT1, DACT2 and DACT3 expression was analyzed in biopsy specimens from 10 cases of newly diagnosed children with asthma and 10 healthy controls by reverse transcription-quantitative polymerase chain reaction, and their expression was confirmed in RAW264.

[Correlation Study between Electronic Bronchus Mirror and Chinese Medical Syndrome TVDinci of Mycoplasma pneumonia Children].

Objective: To explore the correlation between electronic bronchus mirror and Chinese medical syndrome typing of Mycoplasma pneumonia children.

Methods: Totally 198 Mycoplasma pneumonia children inpatients were assigned to three syndrome types according to Chinese medical syndrome typing and self-formulated typing standards of electronic bronchus mirror, i.e.

[Adenoviral-mediated expression of PTEN cDNA induces apoptosis in endometrial carcinoma cells].

Objective: To investigate whether the human endometrial carcinoma cells, RL95-2 infected with recombinant Ad-PTEN can steadily produce PTEN protein and enter apoptosis.

Methods: The recombinant adenovirus containing PTEN cDNA was constructed using the method of homologous recombination in bacteria. The viral titer was examined by plaque assay and the expression of PTEN protein was detected by western blot assay.
