A novel iPSC model of Bryant-Li-Bhoj neurodevelopmental syndrome demonstrates the role of histone H3.3 in neuronal differentiation and maturation.

Background: Bryant-Li-Bhoj neurodevelopmental syndrome (BLBS) is neurogenetic disorder caused by variants in and the two genes that encode the histone H3.3 protein. Ninety-nine percent of individuals with BLBS show developmental delay/intellectual disability, but the mechanism by which variants in H3.

Expanded phenotypic spectrum of neurodevelopmental and neurodegenerative disorder Bryant-Li-Bhoj syndrome with 38 additional individuals.

Bryant-Li-Bhoj syndrome (BLBS), which became OMIM-classified in 2022 (OMIM: 619720, 619721), is caused by germline variants in the two genes that encode histone H3.3 (H3-3A/H3F3A and H3-3B/H3F3B) [1-4]. This syndrome is characterized by developmental delay/intellectual disability, craniofacial anomalies, hyper/hypotonia, and abnormal neuroimaging [1, 5].

Nitric oxide synthase and its function in animal reproduction: an update.

Nitric oxide (NO), a free radical labile gas, is involved in the regulation of various biological functions and physiological processes during animal reproduction. Recently, increasing evidence suggests that the biological role and chemical fate of NO is dependent on dynamic regulation of its biosynthetic enzyme, three distinct nitric oxide synthase (NOS) according to their structure, location and function. The impact of NOS isoforms on reproductive functions need to be timely elucidated.

Dynamic changes and correlation between symptoms and quality of life in patients with breast cancer during chemotherapy.

Background: Standardized chemotherapy for breast cancer can improve the survival of patients, but during the process, it is accompanied by a variety of symptoms.

Objective: To explore the dynamic changes of symptoms and quality of life in breast cancer patients at different time points during chemotherapy, and to explore the correlation with quality of life.

Method: A prospective study method was used to collect 120 breast cancer patients undergoing chemotherapy as the research objects.

Application of high-frequency ultrasound in the diagnosis of gastrointestinal magnet ingestion in children.

Background: The incidence of magnet ingestion by children has recently increased in China. Magnet ingestion is associated with an extremely high risk of gastrointestinal damage because loops of bowel can become trapped and squeezed between multiple magnets in different locations. However, the lack of imaging sensitivity makes clinical decision-making difficult.

Study on the cohesive shear characteristics and intrinsic modelling of the root-tailing soil interface of Amorpha fruticosa.

To study the soil consolidation effect of shrub plant roots on tailings soil and to explore the frictional characteristics of plant roots on tailings soil, three experimental conditions of the root-soil interface were established by using a modified indoor direct shear instrument with binders such as liquid sodium silicate and cyanoacrylate to conduct direct shear frictional tests at the root-soil interface using the roots of the typical slope protection plant Amorpha fruticosa. The Gompertz improved curve model was established by using the relationship between shear stress and shear displacement and the trend of the root-soil interface parameter index. The results were compared between the improved Gompertz curve model and the Clough-Duncan hyperbolic model, and a two-factor coupled improved Gompertz interfacial intrinsic structure model with normal stress and cohesive strength factor was established.

Value of Ultrasound in Diagnosing Perforation of Congenital Choledochal Cysts in Children.

Objectives: This study aimed to investigate the diagnostic value of ultrasound in children with perforation of congenital choledochal cysts.

Methods: Eligible patients recruited from January 2004 to December 2018 in our hospital were enrolled in this retrospective study. A total of 59 cases of congenital choledochal cysts with perforation were defined as the perforation group, and 100 cases of congenital choledochal cysts without perforation with similar symptoms were defined as the control group.

The impact of air pollution on the transmission of pulmonary tuberculosis.

In this paper, we investigate the relationship between the air pollution and tuberculosis cases and its prediction in Jiangsu, China by using the time-series analysis method, and find that the seasonal ARIMA(1, 1, 0)×(0, 1, 1) model is the preferred model for predicting the TB cases in Jiangsu, China. Furthermore, we evaluate the relationship between AQI, PM2.5, PM10 and the number of TB cases, and find that the prediction accuracy of the ARIMA model is improved by adding monthly PM2.

Ultrasonography with the colonic segment-approach for colonic polyps in children.

Background: Ultrasonography (US) has been widely applied and has validated efficacy in the diagnosis of colonic polyps in children. However, little attention has been paid to improving the detection rate of polyps, optimizing the ultrasonic examination process and reducing misdiagnosis.

Objective: To investigate the diagnostic performance of the colonic segment-approach by US in the diagnosis of colonic polyps in pediatric patients.

[Effects of aerobic exercise and glutamine on oxidative stress and expression of related factors in type 2 diabetic rats].

Objective: To investigate the effects of aerobic exercise and glutamine (Gln) on anti-oxidative stress and inflammatory factors in type 2 diabetes mellitus (T2MD) rats.

Methods: Diabetic rat model was induced by streptozotocin (STZ). Fifty 6-week old male SD rats were randomly divided into 5 groups (n=10), including quiet control group (N), diabetes control group (D), diabetic aerobic exercise group (DE), diabetic glutamine group (DG) and diabetic aerobic exercise glutamine group (DEG).

[Alleles dropout patterns of Y-short tandem repeats in infertile males with Y chromosome microdeletions].

Y chromosomal short tandem repeat (Y-STR) typing is the most commonly used genetic technique in forensic studies. However, there may be a limit to the application of Y-STR in forensic science as Y-STR loci are subject to loss or variation caused by the higher chromosomal structures' spontaneous mutation rate. Located in the long arm of the Y chromosome, azoospermia factor (AZF) have been shown to participate in spermatogenesis and its deletion could cause infertility.

[Effect of litterfall input on soil respiration and its temperature sensitivity in moso bamboo forest under simulated drought.].

Increases in drought frequency and intensity under climate change will have great impacts on the carbon cycle of forest ecosystems. Understanding the responses of soil respiration and its temperature sensitivity to drought is necessary, when we assess whether soil is a carbon sink or source. The effects of litterfall input on soil respiration, temperature sensitivity and its lagging effect were studied in moso bamboo forests under simulated drought by ceiling method in the field with three litterfall treatments, i.

miRNA-23a/CXCR4 regulates neuropathic pain via directly targeting TXNIP/NLRP3 inflammasome axis.

Background: Chemokine CXC receptor 4 (CXCR4) in spinal glial cells has been implicated in neuropathic pain. However, the regulatory cascades of CXCR4 in neuropathic pain remain elusive. Here, we investigated the functional regulatory role of miRNAs in the pain process and its interplay with CXCR4 and its downstream signaling.

[Response of plant leaf traits to grazing intensity in Stipa krylovii steppe.].

Grazing disturbance is one of the ways to influence plant traits, and plant leaf traits actually reflect the adaptability of plants to the environment. In this study, taking Stipa krylovii steppe under different grazing intensities in Hulunbuir as research area, the relationships of leaf traits and the variation of plant traits among plant life-form functional groups was investigated. Results showed that plant traits with different life-forms had no significant difference in S.

[Research progress on the dual-mulching of ridge and furrow technology in dry farming regions of northern China: A review.].

The precipitation exiguity and water deficiency are the major factors limiting crop growth in dry farming regions of northern China. Dual-mulching of ridges and furrows, which have been widely concerned both domestically and internationally, could increase the utilization efficiency of precipitation and crop yield. In this paper, we reviewed the concept and model of dual-mulching of ridges and furrows, its supporting farm machinery and implements as well as its ecological effects on soil and crops.
