High-throughput sequencing (HTS) of antibody repertoire libraries has become a powerful tool in the field of systems immunology. However, numerous sources of bias in HTS workflows may affect the obtained antibody repertoire data. A crucial step in antibody library preparation is the addition of short platform-specific nucleotide adapter sequences. As of yet, the impact of the method of adapter ...

OBJECTIVE To determine if applying chilled solution to exposed cerebral cortex can reduce interictal epileptiform activities in patients during surgery. METHODS Electrocorticography was used to record the epileptiform activity of 12 patients (ages 18-53) undergoing cortical mapping and resection surgery. Interictal spikes were counted at baseline and compared with spikes after applying room t...

Infusion of physiological saline solution into the lumen of a tonically contracted resistance artery in vitro caused active relaxation. After endothelium removal by rubbing, confirmed by scanning electron microscopy and loss of the relaxation response to acetylcholine (1 microM), flow relaxation was reduced from a mean of 70% to 37%. The latter change was significant (p less than 0.01). It is c...

Fragment-based drug discovery has the potential to supersede traditional high throughput screening based drug discovery for molecular targets amenable to structure determination. This is because the chemical diversity coverage is better accomplished by a fragment collection of reasonable size than by larger HTS collections. Furthermore, fragments have the potential to be efficient target binder...

PURPOSE To study, through endoscopy, the postoperative structural changes of the intranasal ostium following external dacryocystorhinostomy and to evaluate the influence of saline solution and 5-fluorouracil. METHODS Fifty patients were distributed into the following groups: Group SS-dacryocystorhinostomy and an injection of saline solution during surgery (13 patients); Group 5--FU1-dacryocys...

We studied the capability of the cricket Gryllus bimaculatus to select one of a pair of odors and to avoid the other in one context and to do the opposite in another context. One group of crickets was trained to associate one of a pair of odors (conditioned stimulus, CS1) with water reward (appetitive unconditioned stimulus, US+) and another odor (CS2) with saline solution (aversive US, US-) un...

INTRODUCTION From a drug discovery point of view, ion channels are very interesting and challenging targets. Over the past decade, great efforts have been made in developing platforms for patch clamp-based high-quality screening of ion channels in discovering new drug candidates as well for evaluating their safety profiles. Indeed, the automated patch clamp (APC) has recently reached the data t...

A series of measurements was made of the diameters of the cells and nuclei of the primary spermatocytes of the snail Helix aspersa in preparations made by embedding in paraffin wax after fixation in a number of different cytological fixatives. These were compared with similar measurements made on the living spermatocytes mounted in suitable saline solutions, and the shrinkage that the cells und...

Animal studies implicate the amygdala and its connections in the recognition of aversive stimuli. A recent PET study demonstrated that the human amygdala and left orbitofrontal cortex show substantial increases in regional cerebral blood flow (rCBF) during exposure to aversive odourants. To examine if aversive gustatory stimuli similarly activate these regions, nine healthy women tasted an aver...

Large-scale pharmacogenomic high-throughput screening (HTS) studies hold great potential for generating robust genomic predictors of drug response. Two recent large-scale HTS studies have reported results of such screens, revealing several known and novel drug sensitivities and biomarkers. Subsequent evaluation, however, found only moderate interlaboratory concordance in the drug response pheno...
