The Chinese mitten crab (Eriocheir sinensis) and the Japanese mitten crab (E. japonica) of the family Varunidae, which are also critical fishery species in their native habitats, including China, Japan, and South Korea, exhibit a rare migration life history for the decapod life cycle. Eriocheir sinensis and E. japonica in South Korea may have originated from speciation or secondary contact in South Korea after speciation of these two species; however, the genetic relationship between these South Korean populations remains unclear, and need to be clarified.
This study examined the population genetic properties of E. sinensis and E. japonica in South Korea to reveal the origin of their co-existence.
Mitochondrial DNA cytochrome c oxidase I sequences of 120 E. sinensis and E. japonica from 6 sampling sites in South Korea were sequenced. Their genetic diversity and haplotype data were compared to previously reported data from the Chinese mainland, Taiwan, Japan, and Russia.
The haplotype network, analysis and E. japonica in South Korea may have originated from secondary contact after their speciation.
Non-small cell lung cancer (NSCLC) poses a salient threat to public health. E3 ubiquitin ligase commonly functions as an anti-tumor role.
This study probed the effect of E3 ligase NEDD4L on A549 cells.
NEDD4L expression in NSCLC and its correlation with NSCLC patient's prognosis were predicted and verified. PD-L1 protein level was measured, and the correlation between NEDD4L and PD-L1 was analyzed. The effects of NEDD4L overexpression on the binding of NEDD4L to PD-L1 and ubiquitination level of PD-L1 were examined. Xenograft tumor model was established in mice. The volume and weight of xenograft tumors were recorded. The proportion of CD8
T cells and contents of IL-2 and INF-γ were detected.
NEDD4L expression was downregulated in NSCLC tissues and A549 cells, and correlated with poor prognosis of NSCLC patients. PD-L1 was upregulated in NSCLC and negatively correlated with NEDD4L. Overexpression of NEDD4L upregulated ubiquitination level of PD-L1 and reduced protein level of PD-L1. Overexpression of NEDD4L decreased tumor volume and weight and enhanced proportion of CD8
T cells and contents of IL-2 and INF-γ.
Collectively, overexpression of NEDD4L suppressed PD-L1 protein level through ubiquitination, thereby enhancing anti-tumor immune response and retarding NSCLC progression.

Since COVID-19 was declared the pandemic by the WHO, it has continued to spread. There is a need for rapid, efficient, and accurate diagnostic kits and techniques to control its spread.
The diagnostic capability of the qRT-PCR-based Real-Q 2019-nCoV Detection Kit and dPCR-based Dr. PCR™ Di20K COVID-19 Detection Kit was compared and evaluated.
Diagnostic tests for COVID-19 were performed using two different COVID-19 kits and 301 individual specimens with confirmed COVID-19 positive/negative at the government-accredited medical institution. Assessment of diagnostic capability was measured through diagnostic sensitivity, specificity, Cohen's Kappa coefficient, and dilutional linearity tests.
The COVID-19 diagnostic test results using two kits and 301 individual specimens perfectly matched the pre-diagnosis results of the medical institution. In addition, the measurement results of diagnostic sensitivity and specificity were "1", indicating high diagnostic capability. Cohen's Kappa coefficient value is "1", which means that the diagnosis concordance between the two kits is "Almost Perfect". As a result of dilutional linearity tests to evaluate their detection capability, both kits were measured with very high detection reliability.
Here, we propose that the dPCR-based Dr. PCR™ Di20K COVID-19 Detection Kit has the advantages of the dPCR method reported in the previous study and is suitable for point-of-care testing (POCT) by overcoming the limitations of space, test time, cross-over contamination, and biosafety due to omitting RNA extraction process.

Coffin-Siris syndrome (CSS) is a rare congenital syndrome characterized by developmental delay, intellectual disability, microcephaly, coarse face and hypoplastic nail of the fifth digits. Heterozygous variants of different BAF complex-related genes were reported to cause CSS, including ARID1A and SMARCA4. So far, no CSS patients with ARID1A and SMARCA4 variants have been reported in China.
The aim of the current study was to identify the causes of two Chinese patients with congenital growth deficiency and intellectual disability.
Genomic DNA was extracted from the peripheral venous blood of patients and their family members. Genetic analysis included whole-exome and Sanger sequencing. Pathogenicity assessments of variants were performed according to the guideline of the American College of Medical Genetics and Genomics. The phenotypic characteristics of all CSS subtypes were summarized through literature review.
We identified two Chinese CSS patients carrying novel variants of ARID1A and SMARCA4 respectively. The cases presented most core symptoms of CSS except for the digits involvement. Additionally, we performed a review of the phenotypic characteristics in CSS, highlighting phenotypic varieties and related potential causes.
We reported the first Chinese CSS2 and CSS4 patients with novel variants of ARID1A and SMARCA4. Our study expanded the genetic and phenotypic spectrum of CSS, providing a comprehensive overview of genotype-phenotype correlations of CSS.

microRNA-mRNA axes that are involved in oxidized low-density lipoprotein (ox-LDL)-induced vascular smooth muscle cells (VSMCs) proliferation/apoptosis imbalance need to be further investigated.
To investigate the functional role of miR-183-5p/FOXO1 in VSMCs and its interaction with ox-LDL.
RNA sequencing was used to detect transcriptome changes of VSMCs treated with ox-LDL. miR-183-5p and FOXO1 expression levels in VSMCs after ox-LDL treatment were assessed using qRT-PCR and western blotting. The regulatory effect of miR-183-5p on FOXO1 has been tried to prove using a dual-luciferase reporter assay. The functions of miR-183-5p, and FOXO1 were analyzed by CCK-8 assay and flow cytometry assay. The tissue samples or serum samples of high fat-feeding mice and carotid atherosclerosis patients were collected, and the levels of miR-183-5p/FOXO1 were analyzed.
RNA sequencing data showed 81 miRNAs including miR-183-5p was significantly changed after ox-LDL treatment in VSMCs. FOXO1, a miR-183-5p's potential tan/apoptosis imbalance in VSMCs. The miR-183-5p/FOXO1 axis can potentially be utilized as the target in the treatment of patients with atherosclerosis.
Traditional Chinese medicine (TCM) has been in use for thousands of years in Asian countries and is rapidly gaining popularity in the Western world. Among different forms of TCM, the traditional Chinese herbal therapy and acupuncture are the most popular modalities. Here, we review the fundamentals of TCMs for clinicians practicing in the West and will also detail the evidence-based utility of Chinese herbal medicine in the management of functional gastrointestinal disorders (FGIDs).
In the recent decades, the popularity and usage of traditional Chinese herbal medicine in FGIDs is increasing in the West. TCMs are commonly utilized by many patients with FGIDs as the conventional therapies do have limitations such as cost, inadequate symptom control and adverse effects. The unfamiliarity of TCM philosophy among clinicians in the West, and shortage of traditional Chinese herbalists remain. The philosophy of TCM is complex and entirely different from the Western medical concepts and is difficult to understandt. Further traditional Chinese herbal therapies are often viewed skeptically by the clinicians in the West for various reasons such as lack of scientific rigor, inconsistencies in the constituents of herbal products, and also concerns due to adverse herb effects. Future clinical trials in FGIDs should focus on herb product quality, herb-drug interactions, and standardized criteria for diagnosis and management outcomes.Carbon tetrachloride (CCl4) is a xenbiotic that can cause cellular damage with free radical production. Calcium fructoborate (CFB) is a boron-based nutritional supplement with antioxidant properties. Calcium fructoborate used in our study is marketed by Future Ceutical Corporation as FruiteX-B, which has a chemical structure similar to the natural form of boron found in edible plants. In this study, it was aimed to determine the antioxidant activity, DNA damage, and histopathological effects of CFB on the liver and kidney tissues of rats in the toxicity induced by CCl4. During 14 days of treatment, 42 wistar albino rats were divided into 7 in each group, control group, olive oil (0.25 ml twice a week), CFB (1 mg/day), CFB-CCl4 (1 mg/day, twice a week 0.5 ml), ZY-CFB (0.25 ml/twice a week, 1 mg/2 times day twice), and CCl4 (0.5 ml twice a week). read more AST, ALT, HDL, LDH, urea, creatinine, triglyceride, total protein and albumin levels were analyzed in the blood serum of rats. The antioxidant defense system enzymes CAT, GR, GPx, SOD activities and GSH, MDA and 8-OHdG levels in liver and kidney tissues were determined and evaluated. In addition, liver and kidney tissues were examined with only hispatological tests. As a result of the findings, it shows that CCl4 disrupts antioxidant defense mechanisms by disrupting some enzyme systems in the kidney and liver. CFB (Fruit-XB), a boronbased dietary supplement, regulates antioxidant metabolism by strengthening biochemical metabolic profiles against oxidation, and also has a protective effect against DNA damage caused by oxidation. Thus, it was concluded that CFB has antioxidant property against CCl4-induced liver and kidney toxicity.The current study explored similarities and differences in parenting stress (PSI) and behaviours in parent reports of autism spectrum disorder (ASD) and attachment disorder (AD). 155 parents whose children had developmental delays and disorders completed the social communication questionnaire, Randolph attachment questionnaire, strengths and difficulties questionnaire, PSI, and parent-child relationship inventory. Parents of children with AD reported greater levels of PSI than parents of children with ASD. Parents of children reaching criteria for both disorders reported the greatest levels of PSI. Limit setting was poorest in parents of children with both classifications, followed by parents of children with AD, and then ASD. Limit setting mediated the relationship between PSI and child behaviour problems for parents of children with ASD less then but not for parents of children with AD. These findings suggest different areas of difficulty for parents of children with these conditions, which may be of help in designing interventions.
