A single molecule of the "two-headed" motor enzyme kinesin can move along a microtubule continuously for many enzymatic turnovers (processive movement), and the velocity produced by one kinesin molecule is the same as that produced by many kinesin molecules (high duty ratio). We studied the microtubule movement driven at 1 mM ATP by biotinated N-terminal fragments of Drosophila kinesin heavy ch...

BACKGROUND: Fertilizer management plays an important role for obtaining satisfactory yields and to increase crop productivity. Nutrient management may be achieved by the involvement of organic sources, bio fertilizers, and micro-nutrients. OBJECTIVES: Assessment effect of chemical and biological fertilizer on seed yield, its components and plant height of...

abstract- declining land productivity associated with decreasing soil organic carbon and nutrients is a significant issue in monoculture production. the field experiment with different rates of fertilizer systems (60 kg ha-1 n + 100 kg ha-1 p, 300 kg ha-1 bio-organic (organic fertilizer), 3 kg ha-1 bioumik (biofertilizer), 30 kg ha-1  n + 50 kg ha-1 p + 150 kg ha-1 bio-organic fertilizer and 30...

Comprehensive bio-simulation from genes to a body is one of the most important research topics in 21st century. However, no single model or simulator can cover whole-body bio-system. Therefore, it is essential to develop environment for integrating heterogeneous bio-simulators. In this article, three types of key issues for integration of bio-simulators are discussed: (1) a wide variety of scal...

This paper reports a soil-based bioassay of rice husk bio-ash impacts on redox properties and rice production. Bio-ash was produced during the pyrolytic process of rice husk as a boiler fuel, after which it was applied as an amendment to a flooded soil. Bio-ash was amended before rice transplanting at different mass rates including 0%, 0.1%, 1% and 5%, which was defined as T1, T2, T3, and T4 re...

We have compared lipoprotein metabolism in, and susceptibility to atherosclerosis of, two strains of male Golden Syrian hamster, the Bio F(1)B hybrid and the dominant spot normal inbred (DSNI) strain. When fed a normal low-fat diet containing approximately 40 g fat and 0.3 g cholesterol/kg, triacylglycerol-rich lipoprotein (chylomicron+VLDL) and HDL-cholesterol were significantly higher (P<0.00...

The possible mechanisms of communications between distant bio-systems by means of optical and UV photons are studied. It is argued that their main production mechanism is owed to the biochemical reactions, occurring during the cell division.. In the proposed model the bio-systems perform such communications, radiating the photons in form of short periodic bursts, which were observed experimenta...

Hydrothermal liquefaction (HTL) of Litsea cubeba seed was conducted over different temperature (250-350°C), time (30-120 min), reactor loading (0.5-4.5 g) and Na2CO3 loading (0-10 wt.%). Temperature was the most influential factor affecting the yields of product fractions. The highest bio-oil yield of 56.9 wt.% was achieved at 290°C, 60 min, and reactor loading of 2.5 g. The presence of Na2CO3 ...

Tumor targeting with immunomodulatory molecules is an attractive strategy to enhance the host's antitumor response. Expression of CD80 (B7-1) and CD86 (B7-2) costimulatory molecules in tumor cells has proven to be an efficient way to enhance their immunogenicity. Here, we studied the effects of tumor targeting with biotinylated recombinant soluble B7-1- and B7-2 immunoglobulin G molecules (bio-...
