Effect of some extrusion factors on soybean crud residue-based floating fish feed was investigated. Extrusion conducted at 20%, 25% and 30% moisture content level, die size 2 mm, 4 mm 6 screw speed 150 rpm, 200 rpm 250 rpm. Pearson square method formulation used to attain a 35% protein catfish requirement. Optimized value content, were 30%, respectively optimized result responses, expansion rat...

Indomethacin or glibenclamide treatments attenuate functional dilation of larger-diameter "feed" arterioles paired with venules in hamster cremaster muscle. We tested the hypothesis that release of cyclooxygenase products from venules is important for functional dilation of third- and fourth-order arterioles. We also tested whether ATP-sensitive potassium channels are important during functiona...

Columnar arrangements of neurons with similar preference have been suggested as the fundamental processing units of the cerebral cortex. Within these columnar arrangements, feed-forward information enters at middle cortical layers whereas feedback information arrives at superficial and deep layers. This interplay of feed-forward and feedback processing is at the core of perception and behavior....

The present study employed dynamic causal modeling to investigate the effective functional connectivity between regions of the neural network involved in top-down letter processing. We used an illusory letter detection paradigm in which participants detected letters while viewing pure noise images. When participants detected letters, the response of the right middle occipital gyrus (MOG) in the...

BACKGROUND The MYC transcription factors are known to be involved in the biology of many human cancer types. But little is known about the Myc/microRNAs cooperation in the regulation of genes at the transcriptional and post-transcriptional level. METHODOLOGY/PRINCIPAL FINDINGS Employing independent databases with experimentally validated data, we identified several mixed microRNA/Transcriptio...

Executive Summary Livestock in Ethiopia has an important economic, functional, and cultural significance. Various functions of livestock include dairy production, meat production, draught labor and transportation. Economically, livestock production accounts for nearly 80% of farmer income 1 in the country. In addition, livestock serves as a “savings account” or a way of building assets. Cultura...

Feedback connections among auditory cortical regions may play an important functional role in processing naturalistic speech, which is typically considered a problem solved through serial feed-forward processing stages. Here, we used fMRI to investigate whether activity within primary auditory cortex (PAC) is sensitive to the perceived clarity of degraded sentences. A region-of-interest analysi...

Feed additives used to supplement dairy rations can increase daily feed cost from 2 to 65 per animal. The economic response (benefit to cost ratio) varies from $2.00 to $12.00 for each dollar invested in a specific additive. Knowledgeable dairy veterinarians must understand the role of each additive, when it will be beneficial, inclusion level, strategies and limitations associated with an addi...

The roles played by ryanodine receptors (RyRs) and inositol 1,4,5-trisphosphate receptors (IP₃Rs) in vascular smooth muscle in the microcirculation remain unclear. Therefore, the function of both RyRs and IP₃Rs in Ca(²+) signals and myogenic tone in hamster cremaster muscle feed arteries and downstream arterioles were assessed using confocal imaging and pressure myography. Feed artery vascular ...
