Heterozygous Variants in KCNJ10 Cause Paroxysmal Kinesigenic Dyskinesia Via Haploinsufficiency.

Objective: Most paroxysmal kinesigenic dyskinesia (PKD) cases are hereditary, yet approximately 60% of patients remain genetically undiagnosed. We undertook the present study to uncover the genetic basis for undiagnosed PKD patients.

Methods: Whole-exome sequencing was performed for 106 PRRT2-negative PKD probands.

Ex Vivo Calcium Imaging for Drosophila Model of Epilepsy.

Epilepsy is a neurological disorder characterized by recurrent seizures, partially correlated with genetic origin, affecting over 70 million individuals worldwide. Despite the clinical importance of epilepsy, the functional analysis of neural activity in the central nervous system is still to be developed. Recent advancements in imaging technology, in combination with stable expression of genetically encoded calcium indicators, such as GCaMP6, have revolutionized the study of epilepsy at both brain-wide and single-cell resolution levels.

Risk factors for hypokalemia and its association with postoperative recovery in patients scheduled for radical gastrectomy: a retrospective study.

Background: Hypokalemia is common in patients of various operations, especially gastrointestinal surgery, which seriously affects the safety and enhanced recovery after surgery. Our study aims to explore the risk factors of preoperative hypokalemia of radical gastrectomy for gastric cancer and analyze its impact on postoperative recovery.

Methods: A total of 122 patients scheduled for radical gastrectomy from September, 2022 to December, 2022 were retrospectively analyzed.

Coptisine Inhibits Influenza Virus Replication by Upregulating p21.

The activation of innate antiviral immunity is a promising approach for combatting viral infections. In this study, we screened Chinese herbs that activated human immunity and identified coptisine as a potent inhibitor of the influenza virus with an EC of 10.7 μM in MDCK cells.

Efficient strategies based on behavioral and electrophysiological methods for epilepsy-related gene screening in the model.

Introduction: With the advent of trio-based whole-exome sequencing, the identification of epilepsy candidate genes has become easier, resulting in a large number of potential genes that need to be validated in a whole-organism context. However, conducting animal experiments systematically and efficiently remains a challenge due to their laborious and time-consuming nature. This study aims to develop optimized strategies for validating epilepsy candidate genes using the model.

Glycyrrhizin Inhibits SARS-CoV-2 Entry into Cells by Targeting ACE2.

Coronavirus Disease 2019 (COVID-19) is a highly infectious and pathogenic disease caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Early in this epidemic, the herbal formulas used in traditional Chinese medicine (TCM) were widely used for the treatment of COVID-19 in China. According to Venn diagram analysis, we found that is a frequent herb in TCM formulas against COVID-19.

YWHAZ variation causes intellectual disability and global developmental delay with brain malformation.

YWHAZ encodes an adapter protein 14-3-3ζ, which is involved in many signaling pathways that control cellular proliferation, migration and differentiation. It has not been definitely correlated to any phenotype in OMIM. To investigate the role of YWHAZ gene in intellectual disability and global developmental delay, we conducted whole-exon sequencing in all of the available members from a large three-generation family and we discovered that a novel variant of the YWHAZ gene was associated with intellectual disability and global developmental delay.

[Effect of Comprehensive Protocol of Integrative Medicine on Motor Function, Activity of Daily Living and Quality of Life in Hemiplegia Patients after Stroke].

Objective: To explore the effects of integrative medicine (IM) rehabilitation protocolon motor function, activity of daily living, and quality of life (QOL) in hemiplegia patients after stroke.

Methods: Totally 120 patients with post-stroke hemiplegia were allocated to four groups using sealed envalope drawing, i.e.

[Relationship between serum adiponectin and bone mineral density in preterm infants].

Objective: To examine serum adiponectin level in preterm infants and to evaluate the relationship between serum adiponectin and bone mineral density in preterm infants.

Methods: Seventy-two appropriate-for-gestational-age neonates were classified into three groups according to their gestational ages: early preterm (31-33(+6) weeks, 13 cases), late preterm (34-36(+6) weeks, 16 cases), and full-term (37-42 weeks, 43 cases). Venous blood was collected at one week of their life to measure serum adiponectin concentration.

Mechanistic analysis of taxol-induced multidrug resistance in an ovarian cancer cell line.

Objectives: To establish a taxol-resistant cell line of human ovarian carcinoma (A2780/Taxol) and investigate its biological features.

Methods: The drug-resistant cell line (A2780/Taxol) was established by continuous stepwise selection with increasing concentrations of Taxol. Cell morphology was assessed by microscopy and growth curves were generated with in vitro and in vivo tumor xenograft models.

[Effects of L-Arg on expression of PI3K and PKB in liver among low-birth-weight newborn rats].

Objective: To measure the expression of phosphatidylinositol 3-kinase (PI3K) and protein kinase B (PKB) in liver tissue among low-birth-weight newborn rats treated with L-arginine (L-Arg) in early life, and to investigate the effect of L-Arg on insulin resistance.

Methods: Eighteen pregnant rats were randomly divided into three groups: control, model and intervention (n=6 each). The control group was fed with normal protein feed (protein content=21%) during pregnancy to establish a normal-birth-weight newborn rat model, and the model and intervention groups were fed with low-protein feed (protein content=10%) during pregnancy to establish a low-birth-weight newborn rat model.

[Relationship between bone turnover markers and bone sound of speed in appropriate-for-gestational-age neonates].

Objective: To investigate the correlation of gestational age (GA) with carboxyterminal propeptide of type I procollagen (PICP), deoxypyridinoline (DPD), and bone sound of speed (SOS) in appropriate-for-gestational-age (AGA) neonates, as well as the relationship between bone turnover markers and bone SOS.

Methods: Sixty-five AGA neonates were included in the study. The neonates were divided into three groups: preterm infant (GA ≤3 4 weeks, 14 cases), late preterm infant (34 weeks View Article and Find Full Text PDF

Ecological risk assessment of genetically modified crops based on cellular automata modeling.

The assessment of ecological risk in genetically modified (GM) biological systems is critically important for decision-making and public acceptance. Cellular automata (CA) provide a potential modeling and simulation framework for representing relationships and interspecies interactions both temporally and spatially. In this paper, a simple subsystem contains only four species: crop, target pest, non-target pest and enemy insect, and a three layer arrangement of LxL stochastic cellular automata with a periodic boundary were established.
