Herein, we describe two counterexamples of the previously reported β/α-selectivity 96/4 for glycosylation using ethyl 2-O-[2,3,4-tris-O-tert-butyldimethylsilyl (TBS)-α-L-rhamnopyranosyl]-3,4,6-tris-O-TBS-thio-β-D-glucopyranoside as glycosyl donor. Furthermore, investigated effects protecting group on rhamnose moieties in with cholestanol and revealed that β-selectivity originated from TBS group...

Abstract. Uncrewed Systems (UxS), including uncrewed aerial systems (UAS) and tethered balloon/kite (TBS), are significantly expanding observational capabilities in atmospheric science. Rapid adaptation of these platforms the advancement miniaturized instruments have resulted an number datasets captured under various environmental conditions by Department Energy (DOE) Atmospheric Radiation Meas...

BACKGROUND The aim of the study was to determine the prevalence of petrosquamosal sinus (PSS) and other temporal bone (TB) anatomical variations in various patients using high-resolution computed tomography (CT). MATERIAL AND METHODS We reviewed clinical and consecutively obtained CT data for 276 TBs of 138 patients. The incidence of TB anatomical variations was compared among patients with rad...

Recent studies have shown that self-generated tactile sensations are perceived as weaker than the same sensations externally generated. This has been linked to a central comparator mechanism that uses efference copy to attenuate the predictable component of sensory inputs arising from one's own actions in order to enhance the salience of external stimuli. To provide a quantitative measure of th...

Repetitive transcranial magnetic stimulation (TMS) has become a popular tool to modulate neuronal networks and associated brain functions in both clinical and basic research. Yet few studies have examined the potential effects of cortical stimulation on general levels of vigilance. In this exploratory study, we used theta-burst protocols, both continuous (cTBS) and intermittent (iTBS) patterns,...

PURPOSE The aim of this study was to evaluate the effect of paracetic acid (PAA) and ozone disinfection on the tensile bond strength (TBS) of silicone-based resilient liners to acrylic resins. MATERIALS AND METHODS One hundred and twenty dumbbell shaped heat-polymerized acrylic resins were prepared. From the mid segment of the specimens, 3 mm of acrylic were grinded off and separated parts we...

Sir, There has been a growing interest in the role of the cerebellum in primary dystonia. Although this role is not yet fully understood (Sadnicka et al., 2012), an elegant paper by Hubsch et al. (2013) in Brain showed that in writer’s cramp, a form of task-specific primary hand dystonia, the cerebellum has lost its ability to modulate sensorimotor plasticity of the motor cortex. As part of the...

In this study we describe cloning and expression of CSAL2, a second member of the spalt gene family in chick. All spalt proteins are characterized by the presence of multiple zinc-finger motifs, which are highly conserved. Mutations in HSAL1, a human spalt gene result in Townes-Brocks syndrome (TBS). We show here that CSAL2 is expressed in many of the tissues affected in TBS, including neural t...

The cohort consisted of 84 IBD patients, 53 with Crohn’s disease (CD) and 31 with ulcerative colitis (UC). Clinical characteristics i.e. age, gender, anthropometry, clinical behaviour, medication were recorded. The BMD was determined by dual-energy X-ray absorptiometry (DXA, Hologic Discovery) at the lumbar spine. TBS was determined by TBS Insight® software (Medimaps, France). The clinical char...

STATEMENT OF PROBLEM Polyetheretherketone (PEEK) can be used as a framework material for fixed dental prostheses. However, information about the durable bond to veneering resins is still scarce. PURPOSE The purpose of this study was to investigate the effect of chemical treatments of PEEK on tensile bond strength (TBS) to veneering resins with special emphasis on surface free energy (SFE) and...
