Eslicarbazepine acetate (ESL, Aptiom™) is a once-daily anticonvulsant, approved as adjunctive treatment of partial-onset seizures (POS). Historical-controlled trials investigating the use of ESL as monotherapy have demonstrated a favorable efficacy and tolerability profile in patients with POS. This prospective, non-interventional study recruited POS patients in 17 hospitals in Spain. After a 3-month baseline period, ESL therapy was initiated as 400mg QD and up-titrated to an optimal maintenance dose based on clinical response and tolerance...

OBJECTIVE: Methylphenidate activates μ-opioid receptors, which are linked to euphoria. μ-Opioid antagonists, such as naltrexone, may attenuate the euphoric effects of stimulants, thereby minimizing their abuse potential. This study assessed whether the combination of naltrexone with methylphenidate is well-tolerated while preserving the clinical benefits of stimulants in subjects with attention-deficit/hyperactivity disorder (ADHD). METHODS: We conducted a 6-week, double-blind, placebo-controlled, randomized clinical trial of naltrexone in adults with DSM-IV ADHD receiving open treatment with a long-acting formulation of methylphenidate from January 2013 to July 2015...

The interactions between a star-shaped hexameric cationic quaternary ammonium surfactant PAHB and calf thymus DNA and induced DNA condensation were investigated by ζ-potential, dynamic light scattering, atomic force microscopy, isothermal titration calorimetry, ethidium bromide exclusion assay, circular dichroism and cytotoxicity assay. With the addition of PAHB, long extended DNA molecules exhibit successive conformational transitions from elongated coil to partially condensed cluster-like aggregate, globules-on-a-string structure, and then to fully condensed globule until the saturation point of interaction between PAHB and DNA, which is slightly above their charge neutralization point...

Cancer is a devastating disease and a large socio-economic burden. Novel therapeutic solutions are on the rise, although a cure remains elusive. Application of microorganisms represents an ancient therapeutic strategy, lately revoked and refined via simultaneous attenuation and amelioration of pathogenic properties. Salmonella Typhimurium has prevailed in preclinical development. Yet, using virulent strains for systemic treatment might cause severe side effects. In the present study, we highlight a modified strain based on Salmonella Typhimurium UK-1 expressing hexa-acylated Lipid A...

Pre-mRNA processing protein 40 (Prp40) is a nuclear protein that has a role in pre-mRNA splicing. Prp40 possesses two leucine-rich nuclear export signals, but little is known about the function of Prp40 in the export process. Another protein that has a role in protein export is centrin, a member of the EF-hand superfamily of Ca(2+)-binding proteins. Prp40 was found to be a centrin target by yeast-two-hybrid screening using both Homo sapiens centrin 2 (Hscen2) and Chlamydomonas reinhardtii centrin (Crcen). We identified a centrin-binding site within H...

The oncogenic transcription factor activator protein-1 (AP-1) is a DNA-binding protein that assembles through dimerization of Fos and Jun protein subunits, their leucine-rich helical sequences entwining into a coiled-coil structure. This study reports on downsizing the proto-oncogene cFos protein (380 residues) to shorter peptides (37-25 residues) modified with helix-inducing constraints to enhance binding to Jun. A crystal structure is reported for a 37-residue Fos-derived peptide (FosW) bound to Jun. This guided iterative downsizing of FosW to shorter peptide sequences that were constrained into stable water-soluble α-helices by connecting amino acid side chains to form cyclic pentapeptide components...

The angiogenin protein (Ang) is a member of the vertebrate-specific secreted ribonucleases and one of the most potent angiogenic factors known. Ang is a normal constituent of human plasma and its concentration increases under some physiological and pathological conditions to promote neovascularization. Ang was originally identified as an angiogenic tumour factor, but its biological activity has been found to extend from inducing angiogenesis to promoting cell survival in different neurodegenerative diseases...

Opioids remain the standard of care for treating moderate to severe pain resulting from surgery or injury in cases of acute pain, and are recommended for patients who have not responded to nonopioid analgesics. Effective management of pain has an impact on clinical course and often depends on achieving an acceptable balance between opioid efficacy, safety, and tolerability. Common opioid-related adverse events such as nausea and vomiting are associated with an overall lower achievement of effective pain management and patient satisfaction...

We develop and combine a novel numerical model, within the Poisson-Boltzmann frame- work, with classical experimental titration techniques for mesoporous silica particles to study the charging behavior as both pH and the amount of monovalent salt are varied. One key finding is that these particles can be considered to have an effectively or apparent electroneutral inner core with an effectively charged rim. As a consequence, the total apparent charge of the particle is several orders of magnitude smaller than that of the bare silica charge, which accounts only for the charged silanol groups of the mesoporous silica particles and which has its major contribution from the interior...

An [FeFe]-hydrogenase from Clostridium pasteurianum, CpI, is a model system for biological H2 activation. In addition to the catalytic H-cluster, CpI contains four accessory iron-sulfur [FeS] clusters in a branched series that transfer electrons to and from the active site. In this work, potentiometric titrations have been employed in combination with electron paramagnetic resonance (EPR) spectroscopy at defined electrochemical potentials to gain insights into the role of the accessory clusters in catalysis...

The obstructive sleep apnoea syndrome (OSAS) may be associated with several eyes disorders, among which the most common is the floppy eyelid syndrome (FES). We intended to highlight the association between OSAS and FES and evaluate the effect of FES treatment with Continuous Positive Airway Pressure (CPAP). A 50-year patient with a 10-year history of snoring, sleep fragmentation and daytime sleepiness associated with several comorbidities has been studied. For six months, several ocular symptoms were present, particularly on waking up in the morning...

The commercially available natural organic dye, carminic acid (CA), an anthraquinone derivative bearing hydroxyl and carboxyl groups as recognition sites was found to be a colorimetric probe for Pb(2+) in perfect aqueous solution under neutral conditions with specific selectivity and high sensitivity. Upon addition of Pb(2+), the absorption maximum of CA showed a large red shift, and the resulted color change from red to purple could be easily identified even by the naked eye. The chemical stoichiometric ratio between CA and Pb(2+) was determined to be 1:2 through Job plot, Pb(2+) titration, and kinetic experiments...

Antioxidant are regularly included in poultry feed as protection from deterioration during storage. Recently the interest for the use of natural phytochemicals in animal diets has been increased. Thymol (THY) has been proven to be an effective antioxidant for extending broiler meat quality during storage with similar action to the widely used butylated hydroxytoluene (BHT). This study evaluates whether THY can also have a protective effect on the feed mash by assessing its antioxidant potential and related changes in fatty acid (FA) balance...

Since the middle of the 19th century, both neurologists and psychiatrists have linked psychosis and epilepsy. Clozapine, the most effective antipsychotic drug, alters electroencephalographic activity and carries a significant risk of causing seizures. Unfortunately, this risk limits the drug's potential use in treating pharmacoresistant psychosis in patients with epilepsy. We present a unique case in which we used clozapine successfully as a last resort treatment for chronic interictal psychosis in a 43-year-old woman with severe pharmacoresistant epilepsy and recurrent status epilepticus...

Herein, ditopic ligand DTA comprised of terpyridine and acetylene segments with only one aromatic π-conjugated building block was designed and synthesized. Driven by metal-ligand coordination interactions, we presented that the use of metal salts can direct the self-assembly of DTA in the generation of fluorescent and electrochemical polymers that entrapped water to form ambidextrous hydrogels. These were characterized by several approaches including fluorescent titrations, UV-vis, circular dichroism, and X-ray diffraction spectra as well as scanning electron microscopy and transmission electron microscopy experiments...

The article presents the results of a polysomnographic study with simultaneous monitoring spontaneous nocturnal erections - Nocturnal Penile Tumescences (NPT) in 69 men with age-related androgen deficiency (AAD). Of these, 45 patients were diagnosed with obstructive sleep apnea syndrome (OSAS). In 34 of the 45 patients with OSAS, regimens of non-invasive ventilation with positive-positive airway pressure (CPAP) were selected. Titration was carried out using automatic CPAP-devices for 2 months. The control group (n=24) comprised men with AAD, matched by the "copy-pair" type without clinical manifestations of respiratory disturbances during sleep...
