Advances in techniques have left very few indications for open surgical extraction of urinary stones currently. These advances notwithstanding, the search continues for medical approaches to urinary stone management. In this study, we perform an in vitro study analyzing the efficiency and prospect of two new complex solutions in urological calcium phosphate calculi dissolution.

New chemolysis for urological calcium phosphate calculi - a study in vitro.

A novel SERM (selective estrogen receptor modulators), 1-(R), a chromene-derived bisbenzopyran, was discovered to alleviate hot flushes and effectively increase vaginal fluidity in rats. Moreover, 1-(R) was found to have beneficial effects on plasma cholesterol and bone metabolism while maintaining antiestrogenic activity in the uterus. The biological profile of its enantiomer 1-(S) was also evaluated.

Novel chromene-derived selective estrogen receptor modulators useful for alleviating hot flushes and vaginal dryness.

As part of a program aimed at the development of selective estrogen receptor modulators (SERMs), novel chromene scaffolds, benzopyranobenzoxapanes, were discovered. Many compounds showed binding affinity as low as 1.6-200 nM, displayed antagonist behaviors in the MCF-7 human breast adenocarcinoma cell line as well in Ishikawa cell line with IC(50) values in the range 0.2-360 nM. On the basis of the side chain substitution, various compounds demonstrated strong inhibitory activity in anti-uterotropic assay. Compound 7-(R) and its major metabolites 5-(R) and 6-(R) were evaluated in several in vivo models of estrogen action. Relative to a full estrogen agonist (ethynyl estradiol) and the SERM raloxifene, 7-(R) was found to be a potent SERM that behaved as antagonist in the uterus and exhibited estrogen agonistic activity on bone, plasma lipids, hot flush, and vagina. The overall pharmacokinetic profile and stability were significantly improved compared to those of the phase 2 development compound 9-(R).

Identification and structure-activity relationships of chromene-derived selective estrogen receptor modulators for treatment of postmenopausal symptoms.

Studies about stress disorders following a disaster have mainly been based on single-event trauma with little emphasis on multiple traumas.

Prevalence and predictors of stress disorders following two earthquakes.

Spinal tuberculosis is the most common manifestation of extrapulmonary tuberculosis. However, there have been few reports on the topic of drug-resistant spinal tuberculosis. The aim of this study was to investigate the efficacy and safety of treatment with a combination of surgery and individual chemotherapy guided by drug susceptibility testing for drug-resistant spinal tuberculosis. We retrospectively analyzed 19 patients with drug-resistant spinal tuberculosis. After surgery, individual chemotherapy was tailored for each patient according to his or her drug resistance profile and previous history of chemotherapy. The patients were followed up clinically and radiologically for an average period of 36 months. Among 19 drug-resistant spinal tuberculosis cases, 16 were multidrug-resistant tuberculosis (MDR-TB), and 3 were non-MDR-TB. The patients with MDR-TB and non-MDR-TB had undergone previous chemotherapy for an average of 12.50 ± 2.00 months (0-55 months) and 5.50 ± 1.20 months (0-60 months), respectively. A total of 16 patients underwent open operations, and the other 3 had percutaneous drainage and local chemotherapy. Patients received individual chemotherapy for an average of 24 months postoperatively. All patients had been cured at the final follow-up. Drug-resistant spinal tuberculosis is mainly acquired through previous irregular chemotherapy and the spread of drug-resistant strains. Treatment with a combination of surgery and individual chemotherapy is feasible in the treatment of severe complications and the prevention of acquired drug resistance.
