We provide an algorithm that converts any instance of the Hamiltonian cycle problem (HCP) into a cubic instance of HCP (3HCP), and prove that the input size of the new instance is only a linear function of that of the original instance. This result is reminiscent of the famous SAT to 3SAT conversion by Karp in 1972. Known conversions from directed HCP to undirected HCP, and sub-cubic HCP to cub...

A thermally induced hexagonal close-packed (HCP) to face-centered cubic (FCC) phase transition was investigated in an α-type Ti35 alloy with twinned structure by situ heating transmission electron microscopy (TEM) and ab initio calculations. TEM observations indicated that the HCP FCC occurred both within matrix/twin at twin boundaries thinner region of film, FCC-Ti precipitated as plates matri...

Classic congenital adrenal hyperplasia affects approximately 1 in 15,000 children. Current treatment strategies using multiple daily doses of hydrocortisone lead to suboptimal outcomes. We tested the hypothesis that nocturnal administration of dexamethasone will suppress the hypothalamic-pituitary-adrenal axis more effectively than standard hydrocortisone treatment by blocking the inherent diur...

for the first time this study reported the success of using nanocrystalline hexagonal close-packed (hcp) nickel (ni) modified composite graphite (cg) electrode (hcp-nano ni/cg) for the electrocatalytic oxidation of glycerol in alkaline medium (0.1 m koh). the hcp-nano ni/cg electrode had an improve response and specificity on the electrocatalytic oxidation of glycerol over the bare cg. the elec...

The present study aimed to examine the effectiveness of silymarin compared to hydrocortisone on clinical and hematological alterations and organ injury (liver and heart) in a low-dose canine lipopolysaccharide (LPS)-induced sepsis model. Fifteen clinically healthy dogs were randomly categorized into three equal groups: Two dogs in group A, LPS (0.10 μg kg-1, IV) was injected (control...

Daun, Jane M., and Joseph G. Cannon. Macrophage migration inhibitory factor antagonizes hydrocortisone-induced increases in cytosolic IkBa. Am J Physiol Regulatory Integrative Comp Physiol 279: R1043–R1049, 2000.—Macrophage migration inhibitory factor (MIF) is an inflammatory cytokine secreted by several cell types, including mononuclear and pituitary cells. It has also been shown to counteract...

A recent experiment [1] suggested that bismuth forms hexagonal close packed (HCP) films on the Ni(111) surface, of heights 3, 5 and 7 layers. A quantum size effect based on free electrons was proposed in explanation. To test this idea, we calculate the total energies of Bi on the Ni(111) surface using density functional theory. We find that HCP film stabilities disagree with the observed odd la...

this study aimed to compare the efficacy of dexamethasone and hydrocortisone in the treatment of acute paediatric asthma. forty seven asthmatic children were randomised to receive either dexamethasone (0.6 mg/ml, maximum 16 mg) in a single dose or hydrocortisone (8-10 mg/kg/day) in 4 equal doses for 2 days. our findings showed that the mean length of hospitalization in children receiving dexame...

BACKGROUND Assessing the relative success of serial strategies for increasing healthcare personnel (HCP) influenza vaccination rates is important to guide hospital policies to increase vaccine uptake. OBJECTIVE To evaluate serial campaigns that include a mandatory HCP vaccination policy and to describe HCP attitudes toward vaccination and reasons for declination. DESIGN Retrospective cohort...

tions of hydrocortisone and cortisone to man have established the plasma half-life of hydrocortisone to be 2 hours and that of cortisone 1 hour (1, 2). From isotopic determinations in urine, the half-life of hydrocortisone in the body has been found to be 6 hours and that of cortisone 3.6 hours (3, 4). Thus, cortisone is not only cleared from the plasma more rapidly than hydrocortisone but it i...
