As one of the most troublesome complications in patients with chronic renal disease, the etiology of uremic pruritus remains unknown, and the current therapeutic approaches are limited and unsatisfactory. To identify potential biomarkers for improving diagnosis and treatment and obtain a better understanding of the pathogenesis of uremic pruritus, we compared serum metabolome profiles of severe uremic pruritus (HUP) patients with mild uremic pruritus (LUP) patients using ultraperformance liquid chromatography-quadruple time-of-flight mass spectrometry (UPLC-QTOF MS)...

Using mRNA transcript levels for key functional enzymes as proxies for the organohalide respiration (OHR) rate, is a promising approach for monitoring bioremediation populations in situ at chlorinated solvent-contaminated field sites. However, to date, no correlations have been empirically derived for chlorinated solvent respiring, Dehalococcoides mccartyi (DMC) containing, bioaugmentation cultures. In the current study, genome-wide transcriptome and proteome data were first used to confirm the most highly expressed OHR-related enzymes in the bioaugmentation culture, KB-1TM, including several reductive dehalogenases (RDases) and a Ni-Fe hydrogenase, Hup...

Mallika Bariya, Irina Nayberg
Half-unit insulin pens (HUPs) offer finer gradation of insulin dosing than their integer-unit counterparts, tackling the inaccuracies of dose rounding that make it difficult for insulin-sensitive populations to achieve tight glycemic control. This article analyzes the first prefilled HUP, the Humalog Junior KwikPen, in the context of other, similar devices and the developing landscape of smart insulin pens. The Junior KwikPen's suitability for pediatric patients is assessed in reference to a recent study surveying its accuracy and usability under varying conditions intended to simulate real-world use...

ETHNOPHARMACOLOGICAL RELEVANCE: Alzheimer's disease (AD), a deleterious neurodegenerative disorder that impairs memory, cognitive functions and may lead to dementia in late stage of life. The pathogenic cause of AD remains incompletely understood and FDA approved drugs are partial inhibitors rather than curative. Most of drugs are synthetic or natural products as galanthamine is an alkaloid obtained from Galanthus spp. Huperzine A, an alkaloid found in Huperzia spp., gingkolides a diterpenoids from Gingko biloba and many ethnobotanicals like Withania somnifera (L...

Helicobacter pylori (H. pylori) colonizes under harsh acidic/oxidative stress conditions of human gastrointestinal tract and can survive there for infinitely longer durations of host life. The bacterium expresses several harbinger proteins to facilitate its persistent colonization under such conditions. One such protein in H. pylori is histone-like DNA binding protein (Hup), which in its homo-dimeric form binds to DNA to perform various DNA dependent cellular activities. Further, it also plays an important role in protecting the genomic DNA from oxidative stress and acidic denaturation...

The efficiency of hydrogen gas production by nitrogenase in bacteria has been improved by the inhibition of antagonistic activity by the uptake hydrogenase. In this study, a mutant lacking the gene coding for the uptake hydrogenase was generated from the photosynthetic beta-proteobacterium Rubrivivax gelatinosus IL144 to explore new ways of hydrogen gas production driven by light energy. The mutant cells produced 25-30% higher amounts of molecular hydrogen than the wild-type cells under nitrogen-deficient conditions under light...

AIM OF THE STUDY: As most cardiopulmonary resuscitation (CPR) efforts last longer than 15min, the aim of this study was to compare brain blood flow between the Head Up (HUP) and supine (SUP) body positions during a prolonged CPR effort of 15min, using active compression-decompression (ACD) CPR and impedance threshold device (ITD) in a swine model of cardiac arrest. METHODS: Ventricular fibrillation (VF) was induced in anesthetized pigs. After 8min of untreated VF followed by 2min of ACD-CPR+ITD in the SUP position, pigs were randomized to 18min of continuous ACD-CPR+ITD in either a 30° HUP or SUP position...

Coadministering pyrazinamide (PZA) with the xanthine oxidase inhibitor allopurinol increases systemic levels of the active metabolite, pyrazinoic acid (POA), but the effects on bactericidal activity against tuberculosis are unknown. We randomized healthy volunteers to take a single dose of PZA (either 10 or 25 mg/kg of body weight) at the first visit and the same dose 7 days later, coadministered with allopurinol (100 mg daily; 2 days before to 1 day after the PZA dose). Blood was drawn at intervals until 48 h after each PZA dose, and drug levels were measured using liquid chromatography-tandem mass spectrometry...

AIMS: Alzheimer's Disease (AD) is characterized by a loss of cognitive function and also the accumulation of β-amyloid peptide (βAP) in the brain parenchyma, which plays an important role in this disease. However, it is often also associated with the non-cognitive symptoms such as loss of muscle function (Inclusion-Body Myositis-IBM). MAIN METHODS: Sprague-Dawley rats (13 weeks-n=68) were randomly assigned into five groups: Group C: Control; Group D: d-galactose; Group O+D: Bilateral oophorectomy+d-galactose; Group O: Bilateral oophorectomy; Group O+D+H: Bilateral oophorectomy+d-galactose+Hup-A...

Dehalococcoides mccartyi is a small, slow-growing bacterium of the phylum Chloroflexi that conserves energy using aliphatic and aromatic organohalides as electron acceptors, and hydrogen as sole electron donor. A recent study identified a protein complex in the membrane of strain CBDB1 comprising a Hup hydrogenase, a complex iron-sulphur molybdoprotein and a reductive dehalogenase (RdhA) that catalyses reduction of 1,2,3,4-tetrachlorobenzene. Using a combination of size-exclusion chromatography, in-gel hydrogenase activity-staining, immunological analysis and mass spectrometry, we identified here a large molecular mass protein complex solubilized from the cytoplasmic membrane of D...

Huperzine A (Hup A), the alkaloid produced by the Chinese medicinal plant Huperzia serrata, has been documented to be a promising agent for the treatment of Alzheimer's disease due to its potent acetylcholinesterase inhibitory (AChEI) activity. The search for anticholinesterase natural products, as well as for alternative sources of Hup A in Mexican lycopods, prompted us to investigate these plants. The action of methanolic and alkaloidal extracts of three Huperzia species (H. cuernavacensis, H. dichotoma, and H...

Huperzine A (Hup-A) is a poorly water-soluble drug with low oral bioavailability. A self-microemulsifying drug delivery system (SMEDDS) was used to enhance the oral bioavailability and lymphatic uptake and transport of Hup-A. A single-pass intestinal perfusion (SPIP) technique and a chylomicron flow-blocking approach were used to study its intestinal absorption, mesenteric lymph node distribution and intestinal lymphatic uptake. The value of the area under the plasma concentration-time curve (AUC) of Hup-A SMEDDS was significantly higher than that of a Hup-A suspension (P<0...

Helicobacter pylori is a Gram-negative bacterium that colonizes the human gastric mucosa and causes peptic ulcers and gastric carcinoma. H. pylori strain 26695 has a small genome (1.67 Mb), which codes for few known transcriptional regulators that control bacterial metabolism and virulence. We analyzed by qRT-PCR the expression of 16 transcriptional regulators in H. pylori 26695, including the three sigma factors under different environmental conditions. When bacteria were exposed to acidic pH, urea, nickel, or iron, the sigma factors were differentially expressed with a particularly strong induction of fliA...
