Breaking through the milligram floor When chemists synthesize compounds, threshold for success is at least a of product. This has been true decades—even though biochemical assays have long since descended into microgram territory—and results in part from constraints characterization methods. Buitrago Santanilla et al. present an automated dosing and protocol optimizing chemical reaction conditions on scale. allowed them to screen numerous base ligand combinations catalytic C-N bond-forming...

Metabolic phenotyping is poised as a powerful and promising tool for biomarker discovery in inherited metabolic diseases. However, few studies applied this approach to mcopolysaccharidoses (MPS). Thus, innovative functional may unveil comprehensive impairments MPS biology. This study explores mcopolysaccharidosis VI (MPS VI) or Maroteaux⁻Lamy syndrome (OMIM #253200) which an autosomal recessive lysosomal storage disease caused by the deficiency of arylsulfatase B enzyme. Urine samples were...

Steroids play a key role in numerous physiological processes. Steroid determination is useful tool to explore various endocrine diseases. Because of its specificity, mass spectrometry considered be reference method for the steroids serum compared radioimmunoassay. This technology could progress towards more automation optimal organization clinical laboratories and ultimately benefit patients.

The employment of ethylenediaminetetraacetic acid (EDTA) across several fields in chemistry and biology has required the creation a high number quantitative assays. Nonetheless, determination trace EDTA, especially biologics vaccines, remains challenging. Herein, we introduce an automated high-throughput approach based on EDTA esterification 96-well plates using boron trifluoride-methanol combined with rapid analysis by ultra-high-performance liquid chromatography–triple quadrupole tandem...

(1) Background: Glioblastoma is the most common malignant brain tumor in adults. Its etiology remains unknown cases. pathogenesis consists of a progressive infiltration white matter by tumoral cells leading to neurological deficit, epilepsy, and/or intracranial hypertension. The mean survival between 15 17 months. Given this aggressive prognosis, there an urgent need for better understanding underlying mechanisms glioblastoma unveil new diagnostic strategies and therapeutic targets through...

Both the physiological role of muscarinic receptors for bladder function and therapeutic efficacy antimuscarinic agents overactive syndrome are well documented. We investigated effect with different subtype selectivity on urodynamic parameters in nonhuman primates rodents compared plasma levels these between species. Anesthetized rhesus monkeys were transurethrally catheterized, was infused saline. Urodynamic measured before after intravenous drug administration. Tolterodine (nonselective)...

Nicardipine hydrochloride is an anti-hypertensive drug that used off-label to treat hypertension in children. A previous oral formulation of nicardipine was developed using a commercial vehicle as excipient. However, ready-to-use vehicles are prone supply shortages, and their composition may undergo substantial modifications. The aim this study propose new 2 mg/mL simple excipients. included hydroxypropylmethylcellulose, syrup, polysorbate 80, sodium saccharin, citrate buffer, strawberry...

Abstract Ivermectin is a parasiticide commonly used in humans and livestock. It currently under development for the treatment of pediculosis (head lice) that does not respond to established treatments. A liquid chromatography/turbo ion spray tandem mass spectrometry (LC/TIS‐MS/MS) method determination ivermectin rat human plasma has been developed uses emamectin [4″‐epi‐(methylamino)‐4″‐deoxyavermectin] as internal standard. Sample preparation involved protein precipitation filtration...
