Cancer-stromal interaction is a critical process in tumorigenesis. Conventional dish-based co-culture assays simply mix two cell types in the same dish; thus, they are deficient in controlling cell locations and precisely tracking single cell behavior from heterogeneous cell populations. Microfluidic technology can provide a good spatial-temporal control of microenvironments, but the control ha...

Commercial elemental iron powders (electrolytic and reduced iron), as well as heme iron supplements, were tested for efficacy in improving the iron status of women. In a randomized, double-blind trial, 51 women with moderate to low iron stores received daily for 12 wk: 1) placebo, 2) 5 mg iron as heme iron or 50 mg iron as 3) electrolytic iron, 4) reduced iron, or 5) FeSO(4). Treatments were pr...

Plasma electrolytic oxidation (PEO) was performed on a 1010 Aluminum alloy. To achieve thenanocomposite structure, Si3N4 nanoparticles were added into the electrolyte. In an alkaline aqueoussuspension (silicate-based), the effect of adding NiSO4 on the applied voltage, microstructure,composition, wear, and corrosion resistance of PEO coatings was investigated using ScanningElectron Microscopy (...

www.waterinfocenter.com The biocidal effects of copper and silver have been used for centuries. The early Greeks and Romans made water storage and drinking vessels out of these metals, and enough dissolved in the water stored in them to produce substantial disinfection. More recently, copper and silver ions have been used in hospital, recreational, drinking and industrial water systems. Unlike ...

A remaining useful life prediction methodology for electrolytic capacitors is presented. This methodology is based on the Kalman filter framework and an empirical degradation model. Electrolytic capacitors are used in several applications ranging from power supplies on critical avionics equipment to power drivers for electro-mechanical actuators. These devices are known for their comparatively ...

Intracerebroventricular administration of corticotropin-releasing hormone (CRH) elicits a constellation of behavioral, autonomic, and endocrinological changes typically observed in stress. One of the behavioral changes after intracerebroventricular CRH is a profound increase of startle amplitude (CRH-enhanced startle). The present study examined the role of the septum in CRH-enhanced startle. T...

Cell loss in most adult vertebrate brain regions is thought to be irreversible. Here, we explore the effects of electrolytic lesions on the induction of cell proliferation and newborn neurons in the ventromedial nuclei (VMN) of the hypothalamus in young and adult ring doves. The hypothalamus does not normally recruit new neurons. Bromodeoxyuridine (BrdU) and tritiated thymidine ([3H]Thy) were u...

The glucose metabolism in the mediodorsal thalamus (MD) is increased in rats in the activity-based anorexia (ABA) model. In patients, electrical stimulation in hyperactive brain regions reduced symptoms in e.g. major depressive disorder and cluster headache. In two blinded randomised controlled experiments, we therefore examined the effects of high-frequency electrical stimulation and an electr...

Sensors are essential to the fulfillment of every condition of haptic technology, and they need simultaneously to sense shear stress as well as normal force, and temperature. They also must have a strong and simple structure, softness, and large extension. To achieve these conditions simultaneously, we enhanced the sensitivity of sensors utilizing natural rubber (NR)-latex through the applicati...
