The value of concentration of alveolar nitric oxide in diagnosing small airway dysfunction in patients with stable asthma.

Background: Exhaled nitric oxide (FeNO) is a simple, noninvasive, and reproducible test, and FeNO (50 ml/s) is often used to reflect airway inflammation. The peripheral small airway/alveolar nitric oxide (NO) concentration is derived from the output of NO at multiple flow rates. Concentration of alveolar NO (CANO), which has been reported to reflect peripheral small airway inflammation, may be related to parameters that reflect abnormal small airway function.

, a Sweet Potato R2R3-MYB Gene, Improves Salt Stress Tolerance in Transgenic Tobacco.

The MYB (v-myb avian myeloblastosis viral oncogene homolog) transcription factor family plays an important role in plant growth, development, and response to biotic and abiotic stresses. However, the gene functions of MYB transcription factors in sweet potato ( (L.) Lam) have not been elucidated.

Identification of miRNAs in Response to Sweet Potato Weevil () Infection by sRNA Sequencing.

The sweet potato weevil () is an important pest in the growing and storage of sweet potatoes. It is a common pest in the sweet potato production areas of southern China, causing serious harm to the development of the sweet potato industry. For the existing cultivars in China and abroad, there is no sweet potato variety with complete resistance to the sweet potato weevil.

The Epstein-Barr virus noncoding RNA EBER2 transactivates the UCHL1 deubiquitinase to accelerate cell growth.

The Epstein-Barr virus (EBV) transforms resting B cells and is involved in the development of B cell lymphomas. We report here that the viral noncoding RNA EBER2 accelerates B cell growth by potentiating expression of the UCHL1 deubiquitinase that itself increased expression of the Aurora kinases and of cyclin B1. Importantly, this effect was also visible in Burkitt's lymphoma cells that express none of the virus's known oncogenes.

Possibility of inducing tumor cell senescence during therapy.

The treatment options for cancer include surgery, radiotherapy and chemotherapy. However, the traditional approach of high-dose chemotherapy brings tremendous toxic side effects to patients, as well as potentially causing drug resistance. Drug resistance affects cell proliferation, cell senescence and apoptosis.

Linalool inhibits 22Rv1 prostate cancer cell proliferation and induces apoptosis.

Linalool is an unsaturated terpene that can be found in several plants and exhibits various biological activities. The aim of the present study was to investigate the anticancer activity of linalool using the human prostate cancer 22Rv1 cell line. Flow cytometry was employed to study the effects of linalool on the induction of apoptosis, cell cycle progression, loss of mitochondrial membrane potential and cytochrome release, whereas the effects of linalool on apoptosis-associated proteins were investigated by western blot analysis.

Chronic exposure to the gibberellin derivative GA-13315 sensitizes breast cancer MCF-7 cells but not colon cancer HCT116 cells to irinotecan.

13-Chlorine-3,15-dioxy-gibberellic acid methyl ester (GA-13315) is a gibberellin derivative that exhibits selective cytotoxicity to multidrug resistant MCF-7/ADR cells and reverses drug resistance when administered at subtoxic doses in combination with chemotherapy drugs. The present study aimed to investigate the impact of chronic GA-13315 exposure on the chemosensitivity of MCF-7 and HCT116 cell lines. Cells were administered a subtoxic dose of 1 µM GA-13315 for 12 weeks and the sensitivity of the cells to GA-13315, irinotecan and cisplatin, was assessed.

Next-generation sequencing-based genomic profiling analysis reveals novel mutations for clinical diagnosis in Chinese primary epithelial ovarian cancer patients.

Background: Ovarian cancer (OC) is one of the most malignant gynecological tumors, associated with excess death rate (50-60%) in ovarian cancer patients. Particularly, among newly occurred ovarian cancer patients, 70% of clinical cases are diagnosed at the advanced stage, which definitely delay the timely treatment and lead to high mortality rate within 5 years post diagnosis. Therefore, identification of sensitive gene markers, as well as development of reliable genetic diagnosis, are important for the early detection and precise therapy for OC patients.

Determination of d-amphetamine and diphenhydramine in beagle dog plasma by a 96-well formatted liquid-liquid extraction and capillary zone electrophoresis with field-amplified sample stacking.

This paper describes a method for quantification of d-amphetamine and diphenhydramine in beagle dog plasma by organic solvent field-amplified sample stacking (FASS)-capillary zone electrophoresis (CZE), using amlodipine as the internal standard. The separation was carried out at 25 °C in a 40.2 cm × 75 μm fused-silica capillary with an applied voltage of 20 kV using 25 mM phosphate-18.

Combination Immunotherapy Approaches for Pancreatic Cancer Treatment.

Pancreatic ductal adenocarcinoma is a lethal malignant disease with a very low medium survival. Currently, metastatic pancreatic cancer poorly responds to conventional treatments and exhibits an acute resistance to most chemotherapy. Few approaches have been shown to be effective for metastatic pancreatic cancer treatment.

Circulating cell-free DNA and circulating tumor cells, the "liquid biopsies" in ovarian cancer.

Limited understanding of ovarian cancer (OC) genome portrait has hindered the therapeutic advances. The serial monitoring of tumor genotypes is becoming increasingly attainable with circulating cell-free DNA (cf-DNA) and circulating tumor cells (CTCs) emerging as "liquid biopsies". They represent non-invasive biomarkers and are viable, as they can be isolated from human plasma, serum and other body fluids.

Impact of metoprolol treatment on mental status of chronic heart failure patients with neuropsychiatric disorders.

Background: Metoprolol treatment is well established for chronic heart failure (CHF) patients, but the central nervous system side effects are often a potential drawback.

Objective: To investigate the impact of metoprolol treatment on change in mental status of CHF patients with clinical psychological disorders (such as depression, anxiety, and burnout syndrome).

Methods: From February 2013 to April 2016, CHF patients with clinical mental disorders received metoprolol (23.

A prospective study on the impact of heart rate control achieved with metoprolol on cardiac performance, motor function and quality of life in Chinese chronic heart failure patients.

Background: To prospectively evaluate the impact of metoprolol achieved heart rate (HR) on cardiac-motor function and quality of life (QoL) in chronic heart failure (CHF) patients.

Methods And Results: Between February 2013 to April 2016, association of HR reduction with haemodynamic indices, motor function and QoL in CHF patients with HR>80bpm receiving metoprolol 23.75mg or 47.

Draft genome sequence of Bacillus amyloliquefaciens HB-26.

Bacillus amyloliquefaciens HB-26, a Gram-positive bacterium was isolated from soil in China. SDS-PAGE analysis showed this strain secreted six major protein bands of 65, 60, 55, 34, 25 and 20 kDa. A bioassay of this strain reveals that it shows specific activity against P.
