A detailed investigation of the optical and electrochemical properties of two pentathienoacene derivatives, 2,6-bis(trimethylsilyl)-alpha-pentathienoacene (TMS-T5-TMS) and 2,6-bis(triisopropylsilyl)-alpha-pentathienoacene (TIPS-T5-TIPS), as the neutral and oxidized species was performed in the temperature range of 80-300 K. The experimental solution UV/Vis and solid-state Raman spectra were int...

INTRODUCTION A retainer bonded to the lingual surfaces of the mandibular canines (3-3 retainer) is a widely used type of retention. Our aim in this study was to assess the effectiveness of the 3-3 mandibular lingual stainless steel retainer to prevent relapse of the orthodontic treatment in the mandibular anterior region. METHODS The sample consisted of the dental casts of 235 consecutively t...

Effect of dietary treatment levels on body linear measurements of growing Yankasa rams (Ovis aries) fed sorghum (Sorghum bicolor)Moench stover supplemented with graded levels of dried poultry dropping based diets was assessed using thirty growing Yankasa rams (Ovis aries) consisting of five treatments (T1-T5). Each treatment consisted of three replicates with two animals per replicate. T1: were...

BACKGROUND Mild hypercapnia is permitted during surgeries in sitting position under general anesthesia to maintain cerebral regional oxygen saturation (rSO2). However, since hypoventilation may cause gas exchange impairment, we evaluated effects of mild hypercapnia on lung oxygenation during shoulder arthroscopy in sitting position. MATERIAL AND METHODS Forty patients were randomly allocated to...

We attempted to determine whether b1,3-galactosyltransferase b3Gal-T5 is involved in the biosynthesis of a specific subset of type 1 chain carbohydrates and expressed in a cancer-associated manner. We transfected Chinese hamster ovary (CHO) cells expressing Fuc-TIII with b3Gal-T cDNAs and studied the relevant glycoconjugates formed. b3Gal-T5 directs synthesis of Lewis type 1 antigens in CHO cel...

Objectives: The purpose of this study is to evaluate the anesthesia methods by observing hemodynamic changes, oxygen supply and demand balance in order to provide the reference for the Off-Pump Coronary Artery Bypass Grafting (OPCABG) anesthesia management level during OPCABG. Methods: Thirty patients scheduled for elective OPCABG were premedicated with intramuscular scopolamine 0.3 mg/kg and m...

This week we discuss a paper dealing with "Speculative Decoupled Software Pipelining". It bases on last week's paper, but due to the fact that DSWP is not mighty enough to parallelize many loops it expands this approach by using speculation. The problem that arises when certain loops are parallelized is that there are dependence recurrences inhibiting a parallelization using DSWP. To solve this...

Neuronal computation underlying detection of visual motion has been studied for more than a half-century. In Drosophila, direction-selective T4/T5 neurons show supralinear signal amplification in response to stimuli moving in their preferred direction, in agreement with the prediction made by the Hassenstein-Reichardt detector. Nevertheless, the molecular mechanism explaining how the Hassenstei...

BACKGROUND In the fly's visual motion pathways, two cell types-T4 and T5-are the first known relay neurons to signal small-field direction-selective motion responses [1]. These cells then feed into large tangential cells that signal wide-field motion. Recent studies have identified two types of columnar neurons in the second neuropil, or medulla, that relay input to T4 from L1, the ON-channel n...
