We prove that a binary geometry of rank n {n > 2) not containing M(Ky and F-, (respectively, M(K5) and C10) as a minor has at most 3/i 3 (respectively, 4« 5) points. Here, M(K5) is the cycle geometry of the complete graph on five vertices, F-, the Fano plane, and C10 a certain rank 4 ten-point geometry containing the dual Fano plane F* as a minor. Our technique is elementary and uses the notion...

Panax ginseng is a well-known medicinal plant that achieves strong resistance against pathogens while growing in the wild. Due to high market demand for as health food source, cultivation prevalent South Korea. However, continuous monocropping creates problems like irregular growth or vulnerability crop diseases. Quorum sensing (QS) deals with intracellular communication of bacteria and plays r...

DNA adducts of the environmental carcinogen benzo[a]pyrene-7,8-dihydrodiol-9,10-epoxide (BPDE) interact stereospecifically with prokaryotic and eukaryotic polymerases in vitro. Toward understanding the capacity to replicate past different diastereomers of BPDE at specific sites in DNA, six deoxyoligonucleotides, each 33 bases long, were constructed with stereochemically defined BPDE adducts on ...

Objective—Investigate the effects of obesity and high fat diet (HFD) exposure on fatty acid oxidation and TCA cycle intermediates and amino acids in skeletal muscle to better characterize energy metabolism. Design and Methods—Plasma and skeletal muscle metabolomic profiles were measured from lean and obese males before and after a 5 day HFD in the 4h post-prandial condition. Results—At both tim...

Trypanosoma cruzi infection is associated with a severe T cell unresponsiveness to antigens and mitogens characterized by a decreased IL-2 synthesis and by nitric oxide (NO) production. Although spleen cell unresponsiveness to ConA was less severe in infected IFN-gammaR-/- or inducible nitric oxide synthase (iNOS)-/- mice than in control littermates, IL-2 inhibition was as severely impaired. Ag...

Polyester synthesis activity of immobilized Humicola insolens (HiC) was systematically studied with three-series of substrates varying in (i) omega-hydroxyalkanoic acid (omegaHA), (ii) alpha,omega-n-alkane diol, and (iii) alpha,omega-n-alkane diacid chain length. Covalent immobilization of HiC on Amberzyme oxirane (AO) resin (i.e., AO-HiC) was prepared. HiC-AO's activity for omegaHA substrates ...

Supramolecular materials with noncovalent bonds have attracted much attention due to their exclusive properties differentiating them from materials formed solely by covalent bonds. Especially interesting are rotor molecules of topological complexes that shuttle along a polymer chain. The shuttling of these molecules should greatly improve the tension strength. Our research employs cyclodextrin ...

The objective of this study was to evaluate the digestive tract recovery and metabolism feeding either bovine colostrum (BC), transition milk (TM), or replacer (MR) after an episode feed restriction fasting (FRF) in dairy calves. Thirty-five Holstein male calves (22 ± 4.8 d old) were involved a 50-d study. After 3 2 L rehydration solution twice daily 19 h (d 1 study), randomly assigned one 5 tr...
