The first step of the benzoxazinoid (BX) synthesis pathway is catalyzed by an enzyme with indole-3-glycerol phosphate lyase activity encoded by 3 genes, Bx1, TSA and Igl. A gene highly homologous to maize and wheat Bx1 has been identified in rye. The goal of the study was to analyze the gene and to experimentally verify its role in the rye BX biosynthesis pathway as a rye ortholog of the Bx1 ge...

Diffuse axonal injury (DAI) is the predominant mechanism of traumatic brain injury (TBI) after sudden periodic and impulsive events. It is common in all TBI, regardless of severity, and is characterized by a shear action induced on axons by surrounding tissue. DAI leads to progressive changes that may ultimately lead to the loss of connections between nerve cells. The slow progression of events...

Functional assays of proteins can monitor the consequences of defects attributable to posttranslational activating or inhibitory events as well as to genetic mutations. Such assays promise to permit evaluation of cooperating oncogenic or tumor suppressor pathways in cells and tumors. As a step toward realizing this promise, we designed the DNA affinity immunoblotting (DAI) method to measure the...

Effectiveness has become more and more important as a comprehensive outcome measure for (long-term) treatment in schizophrenia. Early predictors to identify patients at a high risk for not succeeding the initiated treatment would be very useful. Discontinuation of the initiated treatment was used as criterion for effectiveness and patients' drug attitude was shown to be predictive for non-adher...

In the case of head trauma, elongation of axons is thought to result in brain damage and to lead to Diffuse Axonal Injuries (DAI). Mechanical parameters have been previously proposed as DAI metric. Typically, brain injury parameters are expressed in terms of pressure, shearing stresses or invariants of the strain tensor. Addressing axonal deformation within the brain during head impact can impr...

BACKGROUND AND OBJECTIVES Infliximab has proven efficacious in the treatment of Crohn's disease. Limited and contrasting data are available on effectiveness of anti-TNF alpha therapy in ulcerative colitis. We evaluated the efficacy of infliximab in the management of steroid-dependent ulcerative colitis. METHODS We report preliminary data from a randomized, open-label, methylprednisolone-contr...

Benzoxazinoids represent preformed protective and allelopathic compounds. The main benzoxazinoid in maize (Zea mays L.) is 2,4-dihydroxy-7-methoxy-1,4-benzoxazin-3-one (DIMBOA). DIMBOA confers resistance to herbivores and microbes. Protective concentrations are found predominantly in young plantlets. We made use of the genetic diversity present in the maize nested association mapping (NAM) pane...

BACKGROUND AND PURPOSE Diffusion tensor imaging (DTI) may be a useful index of microstructural changes implicated in diffuse axonal injury (DAI) linked to persistent postconcussive symptoms, especially in mild traumatic brain injury (TBI), for which conventional MR imaging techniques may lack sensitivity. We hypothesized that for mild TBI, DTI measures of DAI would correlate with impairments in...

The present study was conducted at the Biotechnology Laboratory, Biotechnology Division, Bangladesh Agricultural Research Institute (BARI), Gazipur during the period from September 2004 to June 2005 to investigate the effect of different concentrations of BAP and NAA on virus free plant regeneration, shoot multiplication and different concentrations of IBA and IAA on in vitro root formation of ...
