Low-dimensional lead-halide hybrids are an emerging class of optical functional material but suffer the problems of toxicity and poor air stability. Among lead-free metal halides, tin(IV)-based metal halides are promising optoelectronic materials due to their robust structure and environmental friendliness. However, their photoluminescence (PL) properties are poor, and the underlying mechanisms are still elusive.

Designing and synthesizing cuprous halide phosphors unifying efficient low-energy emission and a broad excitation band is still a great challenge. Herein, by rational component design, three novel Cu(i)-based metal halides, DPCuX [DP = (CHN)(HPO); X = Cl, Br, I], were synthesized by reacting -phenylenediamine with cuprous halide (CuX), and they show similar structures, consisting of isolated [CuX] units separated by organic layers. Photophysical studies uncover that the highly localized excitons and rigid environment give rise to highly efficient yellow-orange photoluminescence in all compounds with the excitation band spanning from 240 to 450 nm.

However, achieving high photoluminescence (PL) properties is still an enormous challenge, and the relationship between the lattice environment and s-electron expression is still elusive. Herein, an organic-inorganic Bi-based halide (CHN)BiCl·Cl·2HO (CHN = doubly protonated 1-methylpiperazine) with a six-coordinated structure has been successfully prepared, which, however, exhibits inferior PL properties due to the chemically inert expression of Bi-6s lone-pair electrons.

Herein, a novel zero-dimensional Sn(IV)-based halide (CHN)SnCl is prepared by assembling inactive quinoline cations and stable [SnCl] polyhedra. Experimental characterizations and theoretical calculations show that the blue emission of (CHN)SnCl centered at 433 nm is derived from the organic cations.

Methods: From January 2017 to January 2018, 26 BPH patients underwent Memokath transurethral STEPS implantation, 9 under the flexible cystoscope and the other 17 under the rigid cystoscope. The patients were aged 62-91 years old, with a prostate volume of 32-78 ml, postvoid residual urine volume (PVR) of (67.
Nitrogen-doped carbon dots (NCDs) were synthesized via hydrothermal treatment of vitamin B1 and triethylamine. The NCDs exhibit strong blue fluorescence (with a peak at 437 nm at an excitation wavelength of 370 nm), good water solubility and excellent fluorescence stability in the pH 3~12 range, at ionic strengths between 0.01 and 1 M, and under UV illumination for 6 h, as well as incubation temperature of 15~60 °C.

rythropoietin-roducing epatocellular carcinoma cell receptor A4 (EphA4) is one of the largest superfamily of human Eph receptor tyrosine kinases. The roles of EphA4 receptor in the development of nervous system have been well documented. More recently, functions of EphA4 receptor in several types of human cancer were reported with a paradoxical result.

Although EphA2 protein expression has been investigated in many types of human carcinomas, the relationship between the expression of EphA2 protein in clear cell renal cell carcinoma was not well documented. In the present study, using specific anit-EphA2 polyclonal antibody and immunohistochemistry, we evaluated EphA2 protein expression levels in clear cell RCC specimens surgically resected from 90 patients.

Background: Long noncoding RNAs (lncRNAs) are pervasively transcribed in the genome and are emerging as new players in tumorigenesis.
Methods: An electronic search of all relevant publications in peer-reviewed journals before April 2014 was performed on PubMed, Google scholar databases. The keywords of long-coding RNAs, lncRNAs, kidney tumor, renal cancers were used for searching.
Objective: The aims of this study were to evaluate the clinical utility of a fluorescence in situ hybridization (FISH) assay as a non-invasive molecular test to distinguish urothelial carcinoma (UC) in the upper urinary tract (UUT) from benign lesions presenting with hematuria.
Study Design: The chromosomal abnormalities of chromosomes 3, 7, 17 and 9 (p16) in hematuria specimens from 34 patients with UUT-UC and 33 patients with benign disorders were detected using a set of fluorescently labeled DNA probes. The abnormalities of the chromosomes were determined and analyzed between UUT-UC and benign disorders.
Aims: Anti-follicle-stimulating hormone (FSH) autoantibody was found to highly correlate with oligospermia and asthenospermia, but the actual effect of FSH autoantibody on spermatogenesis is still unknown.
Main Methods: In this study, 21-day rats were immunized seven times with FSH peptides linked with Keyhole Limpet Hemocyanin (KLH) (experimental group) or KLH (control group) every 2 weeks. Luteinizing hormone (LH) and inhibin B level in the immunized rat sera were measured by enzyme-linked immunosorbent assay (ELISA).

Objective: To investigate the expressions of VEGF in prostate cancer (PCa) and benign prostatic hyperplasia (BPH), their clinical significance and their relationship with that of ET-1.
Methods: A total of 44 specimens of PCa and 36 of BPH tissues were examined by the immunohistochemical Elivision plus method for the expressions of VEGF and ET-1. The intensity of staining for VEGF and ET-1 was assessed by light microscopy on a scale from "-" to "+ + +".
DNA methylation is a common event in malignancies and implicated in tumor initiation and progression. There is a battery of genes involved in critical cell processes such as DNA damage repair, which are hypermethylated in prostate cancer. DNA methylation has also been found in premalignant lesions such as prostatic intraepithelial neoplasia, but to a less extent compared with that in prostate cancer.
