Article Synopsis
  • Scientists are looking for new medicines to help people with lung cancer survive better and live longer.
  • They found that a natural substance called betulinaldehyde can stop lung cancer cells from growing and spreading.
  • The study shows that betulinaldehyde works by changing how the cancer cells handle waste and energy, which could make it a good treatment option for lung cancer in the future.

We designed a study to compare the newly developed 5-mg flunarizine hydrochloride capsules (test) to that of its marketed counterpart (5-mg; reference) among healthy adult Chinese volunteers. We performed an open-label, single-center study that consisted of 2 randomized, crossover trials, including a fasting trial and a fed trial. In each part of the study, the subjects were randomly assigned to either receive the test or reference products (5-mg flunarizine) in a 1:1 ratio.

This study aimed to develop an LC-MS/MS method for determining sildenafil and its metabolites N-desmethylsildenafil and N1,N4-desmethylsildenafil in human plasma and applying it to a pharmacokinetic study of sildenafil in healthy volunteers. Sildenafil-d8 was used as the internal standard. Plasma samples were pretreated via protein precipitation with acetonitrile.

Dissolved carbon (DC) is the most active carbon fraction in soils. Vegetation restoration and reconstruction accelerate the carbon cycle in arid desert regions. Studying the DC distribution in soil profiles of artificial shelterbelt under saline irrigation can provide theoretical support and decision-making basis for artificial shelterbelt management, development, and utilization in arid desert areas.

Ovarian cancer (OC) is a type of gynaecological malignancy with high mortality in females. Serous ovarian cancer (SOC) is a distinct subtype of OC with poor early diagnosis. Given the limitations of traditional therapies, such as chemotherapy, targeted treatment is therefore a promising therapy to improve the survival rate of SOC patients.

The present study focused on exploring the inhibitory mechanism of microRNA (miR)-23a in endometrial cancer. Reverse transcription quantitative polymerase chain reaction (RT-qPCR) was used to investigate miR-23a expression in endometrial tissues and endometrial cancer cells. A colony formation assay using crystal violet staining was performed to compare cell proliferation, while wound-healing and Transwell assays were performed to compare cell migration and invasion.

Object: MicroRNAs (miRNAs) play key roles in progression of cervical cancer. In the present study, we investigated the role of miR-214 in the process of migration, invasion and drug sensitivity to cisplatin in cervical cancer.

Methods: We detected the differential expression of miR-214 in 19 cases cervical cancer tissues and normal tissues as well as 4 cervical cancer cells and one normal cervical cells by Real-time PCR.

Cisplatin (CDDP) resistance becomes a large obstacle of the beneficial therapy for patients with ovarian cancer. MicroRNAs (miRNAs) act as post-transcriptional regulators of multiple genes' expression and have been reported to be involved in multi-drug resistance. The purpose of this study was to determine the roles and molecular mechanism of miR-490-3p in the CDDP resistance in ovarian cancer.

MicroRNAs (miRNAs) are a class of noncoding RNAs and function as key regulators of gene expression at the post-transcriptional level. In this study, we found that miR-495 reduces cell growth, induces apoptosis and suppresses the migration of endometrial cancer by directly inhibiting FOXC1 expression. Further analysis revealed that FOXC1 promotes growth and migration and functions as an oncogene in vitro.

MicroRNAs (miRNAs) are post-transcriptional inhibitor regulators of gene expression that act by directly binding complementary mRNA and are key determinants of cancer initiation and progression. In this study, we revealed a role for the tumor-suppressor miRNA miR-503 in endometrioid endometrial cancer (EEC) cells. The miR-503 expression level gradually decreases across normal endometrial tissues, endometrial tissues with complex atypical hyperplasia, and EEC tissues.

Objective: This study was operated to investigate the association between urinary albumin-to-creatinine ratio (UACR) and physical situations as hypertension and prehypertension among women.

Methods: Blood pressure, height, weight and waist circumference were measured and factors such as cigarette smoking, alcohol intake, family history of hypertension, were investigated. Blood glucose and lipid, serum uric acid, urinary albumin and urinary creatinine were tested on 1796 women aged ≥ 30 years living in the Jinchang district of Suzhou.

Objective: To investigate the association between serum nitric oxide (NO) and hypertension among women in Suzhou.

Methods: Blood pressure, height, weight and waist circumference (WC) were measured and factors including smoking, alcohol intake, family history of hypertension were investigated and blood glucose, blood lipid, serum NO were tested among 1453 women aged ≥ 30 years who lived in Jinchang district of Suzhou. Association between serum NO and hypertension was analyzed by univariate and multivariate methods.

The stabilization of heavy metals in sewage sludge using a ferrous iron is investigated through leaching test and fractionation analysis. The results showed that FeSO4 x 7H2O was not helpful to stabilize the heavy metals in the sludge when used individually since it reduced the pH value of sludge. The pH value dropped significantly from 6.
