In vivo insertion experiments are essential to optimize novel neural implants. Our work focuses on the interaction between intact dura mater of rats and as-fabricated single-shaft silicon microprobes realized by deep reactive ion etching. Implantation parameters like penetration force and dimpling through intact dura mater were studied as a function of insertion speed, microprobe cross-section,...

The effects of the addition of fibres of bacterial cellulose (FBC) to commercial starch of Mater-Bi(®) have been investigated. FBC produced by cultivating Acetobacter xylinum for 21 days in glucose-based medium were purified by sodium hydroxide 2.5 wt % and sodium hypochlorite 2.5 wt % overnight, consecutively. To obtain water-free BC nanofibres, the pellicles were freeze dried at a pressure of...

this study was conducted to evaluate the effects of different heating treatments (autoclaving, roasting, steam flaking and microwave irradiation) on chemical composition, anti- nutritional compounds (tannin and phenolic), in situ dry mater (dm) and crude prate in (cp) degradability. three fistulated bull in a complete randomized block design and in vitro gas production kinetics (complete random...

the aim followed in the present research was to study the effects of reduction in dietary crude protein on milk production and on blood components in lactating holstein dairy cows when in heat stress. a number of 63 holstein dairy cows (71 ± 16.5 dim) were chosen to be made use of in a randomized complete block design. the cows were randomly assigned to any one of the three experimental rations...

BACKGROUND AND OBJECTIVES This study aimed to evaluate the transverse and longitudinal distensibility of the posterior human lumbar dura mater. Results are compared with previous literature on biomechanical property studies. Possible clinical implications were also examined. METHODS Samples of human dural sac were obtained from autopsy studies in three adult male cadavers. Dural sac samples w...

a number of 36 holstein young bulls (initial bw of 345±61 kg) were randomly assigned to 6 dietary treatments, following a 3 × 2 factorial arrangement, with three concentrate levels of fish oil (0, 1.5 and 3 % of dm) and 2 levels of alfalfa hay versus corn silage (10 and 20 % of alfalfa hay forage versus 20 and 10 % of corn silage) were used to investigate the effect of fish oil supplementation ...

abstract in this research we studied the economical effects of rainfed irrigation and 4, 8, 12 and 16 day sprinkler irrigation intervals as well as their effects on water productivity and tea quality. the study was done in fouman tea research station, northern part of iran where tea is a major crop, during growing season of 2002-2004. the results showed that during dry season of 2002 and 2003 y...

Ca(2+) oscillations are a hallmark of mammalian fertilization and play a central role in the activation of development. The calcium required for these oscillations is primarily derived from the endoplasmic reticulum (ER), which accumulates in clusters at the microvillar subcortex during oocyte maturation. The migration of the ER to the cortex during maturation is thought to play an important ro...
