The aim of our study is to understand neuropathic pain's social, psychological, and biological effects on the patients. All of the patients who were diagnosed with neuropathic pain (NP) by a neurologist were invited to participate in the study. The diagnoses were made based on the patients' history and symptoms and the results of their neurological examinations. Demographic characteristics (age and pain duration), diagnoses, and medical histories of the patients were recorded. Average daily pain intensity was measured using a 100-mm visual analogue scale (VAS)...

Despite some encouraging findings for the treatment of neuropathic pain in patients with spinal cord injury (SCI), transcranial direct current stimulation (tDCS) directed to the primary motor cortex (M1) has faced some mixed results. Prior to translating this technology to clinical care, consistent results and durable effects need to be found. We, therefore, aimed to assess the direct and long-term effects of tDCS on pain following SCI. We performed a two-phase randomized sham-controlled clinical trial where patients received 5days of tDCS followed by at 3-month follow-up period (Phase I); then, Phase II consisted of 10days of tDCS with an 8-week follow-up period...

Described is the first synthesis of guanosine diphosphate mannuronic acid (GDP-ManA), the sugar donor used by algae and bacteria for the production of alginate, an anionic polysaccharide composed of β-d-mannuronic acid (ManA) and α-l-guluronic acid (GulA). Understanding the biosynthesis of these polyanionic polysaccharides on the molecular level, opens up avenues to use and modulate the biosynthesis machinery for biotechnological and therapeutic applications. The synthesis reported here delivers multi-milligram amounts of the GDP-ManA donor that can be used to study the polymerase (Alg8 in Pseudomonas aeruginosa) that generates the poly-ManA chain...

International guidelines recommend lifelong nucleos(t)ide analogue (NA) treatment in individuals with chronic hepatitis B (CHB) infection who are hepatitis B e antigen (HBeAg) seronegative, because hepatitis B surface antigen (HBsAg) seroconversion is rarely achieved. However, after terminating therapy, sustained responses and HBsAg loss have been observed. Clinical characteristics identifying persons with favorable outcomes after discontinuing NA therapy have not yet been defined. This case series describes outcomes of 6 individuals with HBeAg-seronegative CHB infection without cirrhosis and low plasma levels of HBsAg who discontinued long-term NA treatment...

Microtubule (MT) is made of αβ-tubulin heterodimers that dynamically assemble into a hollow nanotube composed of straight protofilaments. MT dynamics is facilitated by hydrolysis of guanosine-5'-triphosphate (GTP) and can be inhibited by either anticancer agents like taxol or by the non-hydrolyzable GTP analogues like GMPPCP. Using high-resolution synchrotron X-ray scattering, we have measured and analyzed the scattering curves from solutions of dynamic MT (in other words, in the presence of excess GTP and free of dynamic-inhibiting agents) and examined the effect of two MT stabilizers: taxol and GMPPCP...

The electronic structure and excited-state dynamics of the ubiquitous bioluminescent probe luciferin and its furthest red-shifted analogue infraluciferin have been investigated using photoelectron spectroscopy and quantum chemistry calculations. In our electrospray ionization source, the deprotonated anions are formed predominantly in their phenolate forms and are directly relevant to studies of luciferin and infraluciferin as models for their unstable oxyluciferin and oxyinfraluciferin emitters. Following photoexcitation in the range 357-230 nm, we find that internal conversion from high-lying excited states to the S1(1ππ*) state competes efficiently with electron detachment...

Photophysical parameters and ultrafast dynamics of dimethylaminochalone (DMAC-A) have been compared with a structurally bridged analogue (namely, c-DMAC) in solvents of varying polarities. Conformational locking of the single bond connecting the donor and acceptor groups in c-DMAC arrests the twisted intramolecular charge transfer (TICT) relaxation and consequently the photophysical parameters such as fluorescence yield, fluorescence lifetime and triplet yield change significantly. The intramolecular charge transfer character of the LE state is found to be unaffected by conformational restriction...

AIMS: Betahistine is a histamine analogue that is used for the treatment of Menière's disease. Animal studies showed that it increases local blood flow in the stria vascularis. In terms of its mode of action, recent studies have prompted discussion of whether betahistine actively affects cochlear microcirculation by dilations of pericytes or of precapillary arterioles or by mere downstream effects. Hence, we investigated the effects of betahistine on cochlear capillary pericytes and precapillary arterioles...
