Mannitol is used as an indirect challenge test to assess airway hyperresponsiveness in asthmatic adults and children as young as 4 years old [1–4]. Recently, it has been tested with success in adults as a sputum inducer [5, 6]. In children, induced sputum is usually obtained by hypertonic saline solution (HSS) and has several indications, such as sample obtaining in infectious diseases [7], mon...

Cell movement in the amoebae Dictyostelium discoideum has been examined in media differing in monovalent cation concentration (i.e. Na+ and K+). Under isotonic or even slightly hypertonic conditions, the cells move equally well in solutions in which either potassium or sodium ions dominate. However, in strongly hypertonic solutions the amoebae showed motility in a 2% potassium chloride solution...

BACKGROUND AND OBJECTIVES Bronchiolitis, the most common reason for hospitalization in children younger than 1 year in the United States, has no proven therapies effective beyond supportive care. We aimed to investigate the effect of nebulized 3% hypertonic saline (HS) compared with nebulized normal saline (NS) on length of stay (LOS) in infants hospitalized with bronchiolitis. METHODS We con...

OBJECTIVE To evaluate the predictability and safety of hypertonic saline (5% sodium chloride) [correction]-assisted laser-assisted subepithelial keratectomy (HS-LASEK) vs 20% alcohol-assisted LASEK (A-LASEK). SETTING American Laser Medical Center, Rishon Le-Zion, Israel. METHODS Fifty-two consecutive eyes (26 patients) were randomized to HS-LASEK (30 eyes) and A-LASEK (22 eyes) groups. The ...

The hypertonic saline test is a useful technique for distinguishing partial diabetes insipidus from psychogenic polydipsia, and for the diagnosis of complex disorders of osmoreceptor and posterior pituitary function. However, there is little information concerning its use in childhood. The experience of using this test in five children (11 months to 18 years) who presented diagnostic problems i...

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 ...

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...

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...

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...
