In addition, urinary phosphorus excretion was frequently regulated by other variables in the network of phosphorus metabolism following a regular phosphorus diet. After low-phosphorus diet intervention, serum phosphate affected the other factors the most, and the 1,25 D level was the main outcome factor, while urinary phosphorus excretion was the most strongly associated variable in the network of phosphorus metabolism. After high-phosphorus diet intervention, FGF23 and 1,25 D played a more critical role in active regulation and passive regulation in the Granger causality analysis.

Variations in dietary phosphorus intake led to changes in the central factors involved in phosphorus metabolism.

Quantitative real-time PCR, Western blot and immunohistochemistry were adopted to examine microRNA-150-5p (miR-150-5p), microRNA-186-3p (miR-186-3p) and kinesin family member 3 C (KIF3C) expression levels. NSCLC cell proliferation, migration, and invasion were detected through cell counting kit-8 (CCK-8) assay, EdU assay, and Transwell assay. The metastasis of NSCLC cells was evaluated utilizing a pulmonary metastasis model in nude mice in vivo. The targeted relationship among KIF3C 3'UTR, miR-186-3p, and miR-150-5p were verified by dual-luciferase reporter gene assays. It was confirmed that in NSCLC tissues and cells, KIF3C expression level was increased and KIF3C overexpression promoted NSCLC cell proliferation and metastasis. Additionally, miR-150-5p and miR-186-3p directly targeted KIF3C to repress its expression. Our data suggest that KIF3C, which is negatively regulated by miR-150-5p and miR-186-3p, is an oncogenic factor in NSCLC progression.

Infantile myofibromas (IM) are benign soft tissue lesions of childhood and represent a significant portion of the benign spectrum of fibroblastic-myofibroblastic tumors. Cytological diagnosis of these tumors can be challenging because of overlapping morphology and limited case report descriptions. We describe the cytological features and the cytological differential diagnoses.

We describe cytological features of two IMs. The main features were the presence of loose clusters and dispersed bland myofibroblasts in varying stages of maturation with traversing blood vessels and myxoid stroma. The cells typically lacked features of atypia, mitoses and significant pleomorphism.

Diagnosis of IM on the basis of cytology alone can be tricky and definitive diagnosis should be made only after correlating the cytological features with histology. However, bland morphology of differentiating myofibroblasts can aid in cytological diagnosis and help to exclude other malignant spindle cells neoplasms needing preoperative chemotherapy.

Cullin3 (CUL3), an important ubiquitin ligase, can control SHH signaling. In this study, we were dedicated to clarify the roles of SHH and CUL3 in P. gingivalis-LPS (Pg-LPS)-treated periodontal ligament stem cells (PDLSCs). In this study, cell viability was detected using cell counting kit-8 (CCK-8). The inflammatory cytokines of PDLSCs were estimated by enzyme-linked immunosorbent assay (ELISA). With the application of western blots, the protein levels of SHH, Gli1 and NF-E2-related factor 2 (Nrf2) were determined. Alkaline phosphatase staining and Alizarin red staining were performed to evaluate the differentiation and mineralization capabilities of PDLSCs. The apoptotic cells were screened using TUNEL staining. The results showed that Pg-LPS inhibited cell viability and triggered inflammation of PDLSCs. Overexpression of CUL3 weakened the differentiation and mineralization capabilities of PDLSCs. Moreover, CUL3 overexpression aggravated inflammation and cell apoptosis induced by Pg-LPS. It is worth noting that although the protein levels of SHH, Gli1 and Nrf2 were elevated in PDLSCs treated with Pg-LPS, overexpression of CUL3 decreased the expressions of Gli1 and Nrf2. Overall, SHH/Gli1 and Nrf2 were involved in the inflammation and cell apoptosis of PDLSCs, which was dominated by CUL3.

E-cigarette use among college students is increasing. In the era of COVID-19, such usage is especially dangerous given that the virus can be deadly for those with impaired respiratory systems. A small but growing body of research suggests that social norms may predict e-cigarette use. However, one's perception of e-cigarette use behaviors (descriptive norms) and approval by peers (injunctive norms) have yet to be studied in college students. The overarching purpose of this study is to determine whether descriptive and injunctive norms for e-cigarette use contribute unique variance to past 30-day e-cigarette use.

Using a sample of 191 students (138 women) surveyed from introductory-level courses at a university in the northeastern United States, we explored the relationships between student demographic characteristics, alcohol use, binge drinking, COVID-19 non-compliant party attendance on and off campus, and social norms with past 30-day e-cigarette use using sequential regression. Two models were utilizl. Results The results demonstrated that descriptive and injunctive norms for e-cigarette use significantly predicted e-cigarette use in both models, controlling for all covariates. Conclusions/Importance Findings highlight the importance of social norms in predicting e-cigarette use during the COVID-19 pandemic, identifying areas for prevention and intervention for public health officials and higher education administrators.There is a scarcity of research examining the effects of long-distance transmeridian travel (LDTT) on the sleep and match performance of team sport players. Ki20227 in vitro To address this, 37 elite male rugby union players from a Super Rugby team undertaking LDTT were recruited. The participants completed validated sleep questionnaires and wore a wrist-worn activity monitor (Readiband™) during a Super Rugby season (including during periods of LDTT crossing 5, 6, and 13 time-zones) to ascertain objective measures of sleep. Sleep measures were compared using mixed model analysis to ascertain the effects of competition and LDTT on sleep. Total sleep time (TST) increased in the days prior to matches, and decreased following matches (accompanied by a later time at sleep onset), particularly when next-day early-morning flights were required. TST was decreased when sleep was attempted during LDTT, except for in the last travel bout where players napped in addition to achieving night-time sleep. TST was also reduced for the night immediately following LDTT, except for in Condition 3 where players delayed wake time and also achieved naps. This study exemplifies the challenges that team-sport athletes face in obtaining regular sleep when LDTT is required.The PIK3R1 and PHLPP2 genes encode the p85 alpha subunit of PI3K and a phosphatase for AKT, respectively, which play a direct role in regulating the PI3K-AKT pathway that promotes cell survival, growth, and differentiation. While most attention is focused on the factors that positively affect this pathway, negative regulation is equally important. The aim of this study was to investigate the association of SNPs rs61733127 (L1016S) in PHLPP2 gene and rs3730089 (Met326Ile) in PIK3R1 gene with colon and breast cancer, respectively because both SNPs have been reported to play a functional role in corresponding encoded enzymes and both genes are negatively involved in regulating the PI3K-AKT pathway. 139 colon and 149 breast cancers patients and 279 healthy controls were included in the present study. The target SNPs were genotyped using tetra- ARMS-PCR. In addition, the genotypes of 10 samples for each SNP were confirmed by sequencing. Statistical analysis was performed using SPSS 21.0 and by Fisher exact, T, χ2 and logistic regression tests. As revealed, the genotype AG (OR = 2.18, p = 0.001, CI = 1.36-3.50) and allele G (OR = 1.92, p = 0.001, CI = 1.30-2.84) of rs61733127 in the PHLPP2 gene significantly increased the risk of colon cancer. In addition, genotype AA (OR = 0.2, p = 0.001, CI = 3.00-8.00) and allele A (OR = 0.5, p = 0.001, CI = 1.00-4.00) of rs3730089 in the PIK3R1 gene significantly decreased the risk of breast cancer. The results suggest that SNPs in genes involved in regulating of PI3K-AKT pathway can be used as a marker for susceptibility to colon and breast cancers.High levels of adolescent pregnancy and child marriage rates in low- and middle-income countries is an issue of concern to many stakeholders, including in Zambia where almost one-third of women give birth before age 18. The aim of this paper is to explore and analyse social norms concerning adolescents' sexual behaviour within the context of an intervention trial in rural communities in southern Zambia. It is based on a qualitative study applying individual interviews, focus group discussions and participatory research methods. We apply the distinction between injunctive and descriptive norms to demonstrate that adolescent girls are caught between conflicting norms. Injunctive norms express that premarital sex, contraceptive use, and discussions about sex between adults and youths are socially condemned. At the same time poor girls are reported to feel pressure towards having sexual relations for the economic benefits such relations can bring, and this practice is considered so common that it amounts to a descriptive norm. Norms and structural conditions combine to create a disabling and disempowering environment for adolescent sexual and reproductive health, which limits girls' agency and exposes them to unwanted pregnancies.A database of 392 pesticides established by an Ultrahigh performance liquid chromatography-tandem Q/Orbitrap high-resolution mass spectrometer (UPLC-Q/Orbitrap-HRMS) was used to screen multiple residues of pesticides in fruit and raw eaten vegetables from planting farms in Shanghai. Risk assessment was conducted with the screened results of the determined pesticides as to evaluate food safety. In 95% of the samples, one or more pesticides had a content below the maximum residue limits (MRLs) as set in the national Chinese standard. The co-occurrence of multi-residues of pesticides was more severe in peach and muskmelon, when compared with other food. All hazard index values of different groups were in the range of 0.19% to 12.3%, demonstrating that chronic dietary risk of studied fruits and raw eaten vegetables is low and the studied food samples were safe for human consumption in terms of these detected pesticides.
