Attempts to derive structural features of ligand-binding sites have traditionally involved seeking commonalities at the residue level. Recently, structural studies have turned to atomic interactions of small molecular fragments to extract common binding-site properties. Here, we explore the use of larger ligand elements to derive a consensus binding structure for the ligand as a whole. We super...
Hydrogen peroxide (H2O2) produces complex cardiac effects that may involve altered calcium homeostasis. The cardiotoxic effects of H2O2 can be attenuated by adenosine A1 receptor agonists. The present study examined the effect of H2O2 on L-type Ca++ current (ICa,L) in guinea pig ventricular myocytes under two different recording conditions and the influence of adenosine receptor agonists. H2O2 ...
Polymorphisms in the fat mass and obesity-associated gene (FTO) are associated with human obesity and obesity-prone behaviors, including increased food intake and a preference for energy-dense foods. FTO demethylates N6-methyladenosine, a potential regulatory RNA modification, but the mechanisms by which FTO predisposes humans to obesity remain unclear. In adiposity-matched, normal-weight human...
View is a labeled directed graph containing all information about the network that a party can learn by exchanging messages with its neighbors. View can be used to solve distributed problems on an anonymous network (i.e., a network that does not guarantee that every party has a unique identifier). This paper presents an algorithm that constructs views in a compressed form on an anonymous n-part...
The role of spreading somatic cell infections with ecotropic MuLV viruses in the induction of plasmacytomas in BALB/cAN pi mice was determined by constructing congenic mice that lacked the gene locus Cv that codes for ecotropic virus. DBA/2 mice that lack Cv on chromosome (chr) 5 carry a closely linked gene Rmcfr that determines resistance to infection with mink cell focus-forming viruses (MCF)...
The transplantation of human cancer cells into immunodeficient NOD/SCID/IL-2Rγc(null) (NOG) mice often causes highly malignant cell populations like cancer stem cells to emerge. Here, by serial transplantation in NOG mice, we established two highly tumorigenic adult T-cell leukemia-derived cell lines, ST1-N6 and TL-Om1-N8. When transplanted s.c., these cells formed tumors significantly earlier ...
The structure of the RecA-single-stranded DNA complex was investigated by studying the fluorescence emission of poly(deoxy-1,N6-ethenoadenylic acid (poly(d epsilon A)), a fluorescent derivative of poly(dA), under various viscosity conditions. The fluorescence intensity and average lifetime of poly(d epsilon A) are much smaller than those of nonpolymerized monoethenonucleotides (1,N6-ethenoadeno...
Expanding our previous finding of an adenosine-initiated transcription system, we now demonstrate that either the 5' site or the N6 site of adenosine nucleotides can be modified extensively without abolishing their ability to initiate transcription under the T7 phi2.5 promoter. Two series of amino derivatives of adenosine nucleotides were synthesized. Fluorescein and biotin groups were coupled ...
To illustrate the construction of precursor complementary DNAs, we isolated mRNAs from whole venom samples. After reverse transcription polymerase chain reaction (RT-PCR), we amplified the cDNA coding for a neurotoxic protein, phospholipase A2 D49 (PLA2 D49), from the venom of Crotalus durissus collilineatus (Cdc PLA2). The cDNA encoding Cdc PLA2 from whole venom was sequenced. The deduced amin...
This study aims to determine the effects of inclusion waste sesame seed (WSS) concentrate feed on performance, carcass characteristics, and meat fatty acid profile Karayaka lambs. A total twenty-three lambs were randomly allocated a control group (11 lambs, with an average live weight 23.39±0.58 kg) experimental (12 23.55±0.41 kg). Also, each was divided into two subgroups according their gende...
