Surface bonding of MN macrocyclic metal complexes with pyridine-functionalized multi-walled carbon nanotubes for non-aqueous Li-O batteries.

It is essential to develop bifunctional catalysts with high activity and stability for reversible oxygen reduction reactions (ORRs) and oxygen evolution reactions (OERs) in lithium-oxygen (Li-O) batteries. In this work, pyridine (Py) functionalized multi-walled carbon nanotubes (MWCNTs) were prepared to immobilize various solid MN macrocyclic metal complexes (MN-MC) as cathode electrocatalysts for Li-O batteries. Three types of MN-MC molecules, including iron phthalocyanine (FePc), cobalt phthalocyanine (CoPc) and iron protoporphyrin IX (Heme) were examined to evaluate the influence of central metal atoms and ligand substituents found in MN-MC molecules on the electrocatalytic performance of the study samples.

The DeltaN p63 Promotes EMT and Metastasis in Bladder Cancer by the PTEN/AKT Signalling Pathway.

Bladder cancer is a common tumour of the urinary system, and more than 90% is urothelial carcinoma. Therefore, it is important for discovering the key target genes and molecules of bladder tumour cell metastasis and invasion. Our research initially explored the regulation of deltaN p63 on the progression and metastasis of bladder cancer and found that deltaN p63 can influence the occurrence of EMT through PTEN and ultimately regulate the growth and metastasis of bladder cancer.

Simvastatin delays castration‑resistant prostate cancer metastasis and androgen receptor antagonist resistance by regulating the expression of caveolin‑1.

The failure of androgen deprivation therapy in prostate cancer treatment mainly results from drug resistance to androgen receptor antagonists. Although an aberrant caveolin‑1 (Cav‑1) expression has been reported in multiple tumor cell lines, it is unknown whether it is responsible for the progression of castration‑resistant prostate cancer (CRPC). Thus, the aim of the present study was to determine whether Cav‑1 can be used as a key molecule for the prevention and treatment of CRPC, and to explore its mechanism of action in CRPC.

Detecting miRNA biomarkers from extracellular vesicles for cardiovascular disease with a microfluidic system.

According to World Health Organization reports, cardiovascular diseases (CVDs) are amongst the major causes of death globally and are responsible for over 18 million deaths every year. Traditional detection methods for CVDs include cardiac computerized tomography scans, electrocardiography, and myocardial perfusion imaging scans. Although diagnosis of CVDs through such bio-imaging techniques is common, these methods are relatively costly and cannot detect CVDs in their earliest stages.

Management of nocturnal enuresis in Taiwan: Consensus statements of the Taiwan enuresis expert committee.

Nocturnal enuresis causes significant psychological distress to affected children and their family and requires appropriate management. A 12-member expert committee of pediatric urologists and pediatric nephrologists in Taiwan with extensive experience in treating enuresis was established to develop consensus statements and a recommended treatment algorithm for the management of patients with nocturnal enuresis in Taiwan after careful consideration of current evidence, existing guidelines, and expert opinion as well as local practice and culture. The finalized consensus statements were reviewed by and have received endorsement from the Taiwan Urological Association and the Taiwan Pediatric Association.

Associations between arsenic in drinking water and occurrence of end-stage renal disease with modifications by comorbidities: A nationwide population-based study in Taiwan.

Arsenic may affect the function of proximal convoluted tubules and glomeruli, but epidemiological data on the association between arsenic ingestion and end-stage renal disease (ESRD) are limited. Therefore, we conducted a nationwide population-based study in Taiwan, where the incidence of ESRD is the highest in the world, to study the potential association. Using the National Health Insurance Database in Taiwan, we constructed a cohort of 362,505 members with age≥40years in 1998.

May-Thurner syndrome: correlation between digital subtraction and computed tomography venography.

Background/purpose: Digital subtraction venography (DSV) and computed tomography venography (CTV) are both recommended for diagnosing May-Thurner syndrome. The literature contains little information on the correlation between these imaging tools. We performed a retrospective case-series study to investigate this correlation.

Antiangiogenesis as the novel mechanism for justicidin A in the anticancer effect on human bladder cancer.

Justicidin A (JA) is one of the methanol extracts of Justicia procumbens and was reported to induce apoptosis and inhibit the proliferation of human colon cancer cells. Using bladder cancer as a paradigm, this study was designed to identify the novel molecular basis underlying the antiangiogenic activities of JA and its potential in cancer therapy. Human bladder cancer cell lines (TSGH8301 and RT4) and immortalized uroepithelial cell lines (E6 and E7) were chosen to investigate the efficacy of JA in cell proliferation, apoptosis, and angiogenesis in vitro.

Non-inferiority of silodosin to tamsulosin in treating patients with lower urinary tract symptoms (LUTS) associated with benign prostatic hyperplasia (BPH).

Unlabelled: What's known on the subject? and What does the study add? Silodosin administered by 4 mg twice daily is as effective as tamsulosin 0.2 mg daily in treating patients with LUTS associated with BPH. Relative to tamsulosin, silodosin has less cardiovascular side effects as judged by the minimal changes of blood pressure and pulse rats after treatment.

Urinary CD14 as a potential biomarker for benign prostatic hyperplasia - discovery by combining MALDI-TOF-based biostatistics and ESI-MS/MS-based stable-isotope labeling.

Purpose: Quest for specific urinary biomarkers for benign prostatic hyperplasia (BPH).

Experimental Design: Proteomics studies were conducted with urines of the training set to discovering marker candidates that could differentiate BPH from normal subjects by matching results deduced from MALDI-TOF of individual samples and results deduced from nanoLC-ESI-MS/MS-based stable isotope dimethyl labeling of two pooled samples (BPH and normal). Samples were digested before analysis and such an approach takes into account the subject-to-subject variation and differential amount, as well as protein identification.

An unusual function of RON receptor tyrosine kinase as a transcriptional regulator in cooperation with EGFR in human cancer cells.

Homodimerization of RON (MST1R), a receptor tyrosine kinase, usually occurs in cells stimulated by a ligand and leads to the downstream activation of signaling pathways. Here we report that bladder cancer cells, in response to physiological stress, use an alternative mechanism for signaling activation. Time-course studies indicated that RON migrated directly from the membrane to the nucleus of bladder cancer cells in response to serum starvation.

Purpose: Frequent loss of heterozygosity of microsatellites on a specific chromosomal region has been reported in various types of human cancer. The same loss of heterozygosity has also been identified in matched serum or urine DNA. We determined a urine microsatellite marker profile specific to urothelial carcinoma of the upper urinary tract.

Collaboration of RON and epidermal growth factor receptor in human bladder carcinogenesis.

Purpose: Collaboration of heterologous receptor tyrosine kinases has emerged as an important paradigm in tumor progression. We recently proved that RON has an important role in human bladder carcinogenesis. Since epidermal growth factor receptor has been suggested to cross-talk with RON, we examined the significance of epidermal growth factor receptor in modulating RON associated tumorigenesis.
