We evaluated the NCCLS M44-P fluconazole disk diffusion method in comparison with the NCCLS M27-A2 broth microdilution method for determining the susceptibility of 276 isolates of Cryptococcus neoformans. Disk diffusion testing was performed using Mueller-Hinton agar supplemented with 2% glucose and 0.5 microg of methylene blue/ml. Among the 276 isolates, 259 (93.8%) were susceptible, 16 (5.8%)...

Label-free, real-time detection of concentration gradients is demonstrated in a microfluidic H-filter, using an integrated photonic crystal slab sensor to monitor sample refractive index with spatial resolution. The recorded diffusion profiles reveal root-mean-square diffusion lengths for non-fluorescing and non-absorbing molecules, both small (glucose, 180 Da) and large (bovine serum albumin, ...

The diffusivity of water, fucose, proline, lysine, glutamic acid, glucose and sucrose was determined in a variety of inflammatory human synovial fluids. In view of the constituents of pathological synovial fluids one would predict impedence to solute movement. In several fluid diffusivity was enhanced relative to translational diffusion in water. In most fluids diffusivity was enhanced relative...

Abstract In this study, the effect of mesopores in Marimo nanocarbon (MNC) anode material on power generation performance a direct glucose fuel cell was investigated. Three types MNC with different mesopore distributions were used for catalyst support material; Pt as loaded metal. test, containing many pores approximately 35 nm showed highest maximum output density 0.72 mW cm−2 at 5 wt% metal l...

This study aimed to evaluate in vitro free radical scavenging activity and anti-diabetic properties of extracts from the sprout Borassus fabellifier. Antioxidant was performed using DPPH, ABTS, FRAP, SO, NO inhibition methods. The enzymes (α-amylase α- Glucosidase inhibitory activities were investigated. Moreover, glucose adsorption diffusion also studied confirm potential effect B. fabellifier...

Adequate regulation of glucose levels by a microencapsulated pancreatic islet graft requires a minute-to-minute regulation of blood glucose. To design such a transplant, it is mandatory to have sufficient insight in factors influencing the kinetics of insulin secretion by encapsulated islets. The present study investigates factors influencing the glucose-induced insulin response of encapsulated...

A woman aged 68 years who experienced recurrent right hemiparesis caused by hypoglycemia was admitted to our hospital. When she was experiencing a low level of glucose, diffusion-weighted MR imaging showed the presence of hyperintensity lesions in the bilateral internal capsule. Diffusion-weighted MR imaging has been infrequently performed in patients with hypoglycemia. We report the reversible...

Glucose has a central role in fuel economy and is a source of energy storage in the form of glycogen, fat, and protein (see Chapter 87 ). Glucose, an immediate source of energy, provides 38 mol of adenosine triphosphate (ATP) per mol of glucose oxidized. It is essential for cerebral energy metabolism because it is usually the preferred substrate and its utilization accounts for nearly all the o...

The transport of several sugars by cells of Neurospora crassa grown in shake culture has been investigated. 3-OMethyl-n-glucose is a substrate for the glucose transport system in glucose-grown cells but cannot be phosphorylated by the ATP-dependent hexokinase which readily catalyzes the phosphorylation of D-glucose. Since this nonmetabolizable glucose analogue cannot be accumulated against a co...

Insulin action and obesity are both correlated with the density of muscle capillary supply in humans. Since the altered muscle anatomy in the obese might affect interstitial insulin concentrations and reduce insulin action, we have cannulated peripheral lymphatic vessels in lean and obese males, and compared peripheral lymph insulin concentrations with whole body glucose uptake during a euglyce...
