BACKGROUND The present study ascertained the capacities of crude aqueous and ethanolic leaf extracts of Acanthus montanus (ACMO), Asystasia gangetica (ASGA), Emilia coccinea (EMCO), and Hibiscus rosasinensis (HIRO), as well as their combinatorial formulations to ameliorate hyperglycemia in Type I diabetic rats. MATERIALS AND METHODS Hyperglycemia was induced by single intraperitoneal injectio...

This paper presents a new approach to global clock distribution in which traditional tree-driven grids are augmented with onchip inductors to resonate the clock capacitance at the fundamental frequency of the clock node. Rather than being dissipated as heat, the energy of the fundamental resonates between electric and magnetic forms. The clock drivers must only provide the energy necessary to o...

The adequacy of intestinal perfusion during shock and resuscitation might be estimated from intestinal tissue acid-base balance. We examined this idea from the perspective of conventional blood acid-base physicochemistry. As the O(2) supply diminishes with failing blood flow, tissue acid-base changes are first "respiratory, " with CO(2) coming from combustion of fuel and stagnating in the decre...

Nodes in Mobile Opportunistic Network (MON) have to cache packets to deal with the intermittent connection. The buffer management strategy obviously impacts the performance of MON, and it attracts more attention recently. Due to the limited storage capacity of nodes, traditional buffer management strategies just drop messages based on the property of message, and they neglect the collaboration ...

Aquaporins (AQs) increase cell membrane CO(2) diffusivity, and it has been proposed that they may serve as transmembrane channels for CO(2) and other small gas molecules. In addition, it has been hypothesized that voltage-gated H(+) channels located on the apical membrane of the alveolar epithelium contribute to CO(2) elimination by the lung. To test whether these membrane proteins contribute t...

BACKGROUND Blood flow to the liver is partly maintained by the hepatic arterial buffer response (HABR), which is an intrinsic autoregulatory mechanism. Temporary clamping of the portal vein (PV) results in augmentation in hepatic artery flow (augHAF). Portal hyperperfusion impairs HAF due to the HABR in liver transplantation (LT). The aim of this study is to examine the effect of the HABR on bi...

β-alanine is an amino acid that, when combined with histidine, forms the dipeptide carnosine within skeletal muscle. Carnosine and β-alanine each have multiple purposes within the human body; this review focuses on their roles as ergogenic aids to exercise performance and suggests how to best quantify the former's merits as a buffer. Carnosine normally makes a small contribution to a cell's tot...

Objective: The study proposes using the dolomite buffer capacity (BCDolomite) as a method of estimating lime requirement in soils that agronomically require pH increase. Design/methodology/approach: In six soil samples with different levels response to application dolomite, organic matter (OM), content sand, silt and clay, pH, K, Ca, Mg potential acidity (Al+H) were determined. Assuming an appa...
