A novel method for the characterization of polymers by laser desorption/ionization on the layer of graphene nanoparticles coupled with time-of-flight mass spectrometry was demonstrated. Various polymers including polypropylene glycol, polystyrene and polymethyl methacrylate with average molecular weights from 425 to 3500 Da were analyzed.

Each year, almost 3500 children are diagnosed with leukemia, representing approximately 30% of pediatric cancer cases. Acute lymphoblastic leukemia is the most common form of pediatric leukemia, accounting for approximately 80% of cases. A significant number of children fail to respond to existing chemotherapies or are unable to maintain remission. Their prognosis is poor, with little hope for ...

Membrane-bound luminal carbonic anhydrase (CA) IV, by catalyzing the dehydration of carbonic acid into CO2 plus water, facilitates H+ secretion in the renal outer medullary collecting duct from the inner stripe (OMCDi). To examine the role of CA IV on H+ secretion, we measured net HCO3- transport in perfused OMCDi segments and examined the effect on transport of two extracellular CA inhibitors,...

The previous article about material screening for Gerda points out the importance of strict material screening and selection for radioimpurities as a key to meet the aspired background levels of the Gerda experiment. This is directly done using low-level gamma-spectroscopy. In order to provide sufficient selective power in the mBq/kg range and below, the employed gamma-spectrometers themselves ...

Water and carbon monoxide are two major compounds in the predominantly H2 atmospheres of stars, brown dwarfs and extrasolar planets. Recent radiative transfer models suggest that there is an urgent need for data on the pressure broadening of molecular transitions by H2 at high temperatures. We present a set of theoretical H2 pressure broadening parameters for 228 H2O transitions in the range of...

1N-methyl-1S-methyl-2-nitroethylene (NMSM) is an important intermediate in the synthesis of anti-ulcer drug Ranitidine. NMSM is a push pull alkene equivalent to glycine possessing both electron-donating and withdrawing nitro group at both ends of olefinic bond. The solid phase FT-IR and FT-Raman spectra of NMSM have been recorded in the region 4000-400cm and 3500-100cm, respectively. The molecu...

A full-length DNA copy of the M-RNA of cowpea mosaic virus (CPMV), supplied with either the 35S promoter from cauliflower mosaic virus (CaMV) or the nopaline synthase promoter from Agrobacterium tumefaciens, was introduced into the T-DNA region of a Ti-plasmid-derived gene vector and transferred to cowpea Vigna unguiculata cells. Southern blot analysis of the transformed callus tissue obtained ...

The connectivity pattern of networks based on ground level temperature records shows a dense stripe of links in the extra tropics of the southern hemisphere. We show that statistical categorization of these links yields a clear association with the pattern of an atmospheric Rossby wave, one of the major mechanisms associated with the weather system and with planetary scale energy transport. It ...
