Introduction Cryoballoon ablation (CB) has proven effective to treatment of patients (pts) with atrial fibrillation (AF). However, the isolated efficacy of CB to treat pts with long-standing persistent atrial fibrillation (LSPAF) is less know. We analyzed the acute results and the long-term follow-up of our pts suffering LSPAF and initially treated with CB. Methods A cohort of 44 pts, 37 male (...

Para-toluenesulfonamide (PTS) has been implicated with anticancer effects against a variety of tumors. In the present study, we investigated the inhibitory effects of PTS on tongue squamous cell carcinoma (Tca-8113) and explored the lysosomal and mitochondrial changes after PTS treatment in vitro. High-performance liquid chromatography showed that PTS selectively accumulated in Tca-8113 cells w...

Hormesis is an adaptive response of living organisms to a moderate stress. However, its biomedical implication and molecular mechanisms remain to be intensively investigated. Panaxatriol saponins (PTS) is the major bioactive components extracted from Panax notoginseng, a widely used herbal medicine for cerebrovascular diseases. This study aims to examine the hormetic and neuroprotective effects...

Subclinical hypothyroidism (SCHT) is common, with an occurrence of up to 10% of the adult population and defined biochemically only by elevated TSH and normal T4. SCHT affects negatively on lipid and carbohydrate metabolism increasing the risk of ischemic heart disease, affects negatively on cardiac performance and have a close correlation with renal function. The aim of this study is to compar...

TCP performance degrades with increasing round trip time (rtt) due to longer slow start periods and slower rate of increase of the congestion window. The proposed, PTS (proxy transport service) is an active network based service, that can improve the end-to-end performance of TCP connections with large rtt’s. PTS also reduces the response time of TCP to congestion and can be used by other activ...

Introduction: Autonomic heart rate (HR) control evaluated by means of HR variability measures has been widely accepted as important information of cardiovascular function being a marker of sudden death. Methods: Polysomnography was performed in 405 CAD pts (mean age 60.7 yr.) pts, including 200 pts with CHF (mean age 63.4 yr.). Sleep apnea syndrome (SAS) was observed in 46 pts (mean age 64.2 yr...

Partial Transmit Sequence (PTS) technique is an attractive technique for peak-to-average power ratio (PAPR) reduction of orthogonal frequency division multiplexing (OFDM) signals. However, optimum PTS (OPTS) requires an exhaustive search over all combinations of allowed phase weighting factors, resulting in high computational complexity. In this paper, we propose an Alternate Optimised Grouping...

Public Transport system (PTS) is an important and an essential part of urban and rural dwellers. PTS enables a smooth mobility of people and goods. Without PTS no city can improve the standard of living of the people and can make progress. As the population continues to increase, many problems arise which make the PTS an unreliable and inefficient service provider. So, providing a good PTS is r...

Dear Editor, Upper extremity deep vein thrombosis (UEDVT) refers to thrombosis of the subclavian (18% to 69%), axillary (5% to 42%) or brachial vein (4% to 13%).1 It accounts for 4% to 10% of all cases of deep vein thrombosis1 and can result in pulmonary embolism (PE) or post-thrombotic syndrome (PTS) of the arm and even death in severe cases.1 We describe a case of UEDVT in a healthy young Chi...

Results Among 130 pts included in the study, 119 (91%) could be evaluated. BL characteristics: median age 44, female 24%, current smokers 53%. Previous AIDS 29%, CD4 count 502/mm. Time on ARV therapy 42 months. Previous therapy: efavirenz 38%, 3 NRTI 12%, PI 50%. Accompanying nucleosides were tenofovir/emtricitabine in 69%, and abacavir/lamivudine in 31%. Table 1 shows the 24-week results of li...
