A copper-catalyzed regio- and intermolecular aminofluorination of styrenes has been developed. In this reaction Ph-I=N-Ts and Et3N·3HF act as nitrogen and fluorine sources, respectively. The obtained β-fluoro-N-Ts-phenethylamines can be N-alkylated with subsequent deprotection affording the corresponding β-fluoro-N-alkylated phenethylamines, which are interesting building blocks for compounds a...

Background: Tubal sterilizatio (TS) is a widely applied contraceptive method worldwide. Although most studies have described sterilization as a safe method, there are reports of TS complications. The aim of this study was to evaluate the effects of TS on ovarian function. Materials and Methods: The study comprised of 2 protocols A and B. A Protocol: survey ovarian hormone and B protocol: study ...

OBJECTIVE Transsphenoidal surgery (TS) is the primary therapy for Cushing's disease (CD). The aims of this retrospective study were twofold: (i) investigate early and late results of TS for CD, and (ii) evaluate various postoperative tests in order to predict the outcome of TS. METHODS We reviewed the long-term outcome in 79 patients with CD who underwent TS (median follow-up 84 months, range...

OBJECTIVES/HYPOTHESIS Trigeminal sensation (TS) within the nasal cavity is important for the perception of nasal airflow. The objective of this study is to examine whether impaired TS contributes to the sensation of nasal obstruction in patients with chronic rhinosinusitis (CRS). STUDY DESIGN Prospective case-control study conducted in a tertiary referral rhinology clinic. METHODS Cases con...

AIMS The purpose of this study was to determine the effect of exercise on dyssynchrony in patients with left ventricular dysfunction. METHODS AND RESULTS Sixty patients with a left ventricular ejection fraction (LVEF) ≤ 35% were studied. Interventricular mechanical delay (IVMD), intraventricular mechanical delay [Ts-(lateral-septal)], and left ventricular filling ratio were measured at rest a...

Gastric cancer is the most common cancer and the most frequent cause of cancer death worldwide. Several studies have identified the role of thymidylate synthase (TS) 5'- and 3'-UTR and gastric cancer susceptibility; however, the results still remain inconclusive. The purpose of this meta-analysis was to reinvestigate this correlation. In the present study, online databases were searched to retr...

This randomized controlled trial will compare oral 5-fluorouracil derivatives, TS-1, with intravenous standard chemotherapy such as taxanes in women with metastatic or recurrent breast cancer. Patients with hormone-resistant breast cancer are assigned to either TS-1 (40-60 mg twice daily for 28 consecutive days, followed by a 14-day rest period) or standard chemotherapy (docetaxel 60-75 mg/m(2)...

Improvement of sludge dewaterability is important for reducing the total costs for the treatment and disposal of sludge in wastewater treatment plants. In this study, we investigate the use of hydrogen peroxide as an oxidizing reagent for the conditioning of waste activated sludge. Significant improvement to sludge dewaterability was attained after the addition of hydrogen peroxide at 30 mg/g T...

Musculotendinous (MT) stiffness of the triceps surae (TS) muscle group was quantified in 28 prepubertal children (7-10 yr) by using quick-release movements at different levels of submaximal contractions. Surface electromyograms (EMG) of each part of the TS and of the tibialis anterior were also recorded. A stiffness index, defined as the slope of the angular stiffness-torque relationship (SIMT-...

Experimental evidence has revealed that several thymidylate synthase (TS) DNA polymorphisms modulate gene expression, which, in turn is known to be down-regulated by oestrogen receptor subtypes. Consequently, this process might be influenced by female hormones. Based on these data, we investigated whether patient's gender and TS polymorphism exert an interactive effect on the clinical evolution...
