Heteroleptic calcium amides effect the catalytic dimerisation of the terminal alkyne CH(3)OCH(2)C[triple bond, length as m-dash]CH to the hexatriene (CH(3)OCH(2))CH[double bond, length as m-dash]C[double bond, length as m-dash]C[double bond, length as m-dash]CH(CH(2)OCH(3)) under mild conditions; the reaction is proposed to occur via a dimeric calcium acetylide intermediate and to be promoted b...

DOI: 10.21276/sjams.2017.5.9.21 Abstract: Milk of calcium of the kidneys and nephrolithiasis are two different entities. Milk of calcium in the pelvicalyceal system can mimic calculus and contrast in the pelvicalyceal system if bilateral. Their differentiation is important as their management differs. It can be seen in the urinary tract, in the GIT, bronchogenic cyst and adrenal cyst. The usual...

To the Editor: We read with great interest the article “Serum Vitamin D Insufficiency Is Related to Blood Pressure in Diabetic Pregnancy” by Weinert and colleagues1 dealing with the relationships between the calcium metabolism and blood pressure regulation in pregnant women with gestational diabetes mellitus. The results of their study demonstrated that diabetic pregnant women with 25-hydroxyvi...

Objective- To determine the prevalence of nutritional secondary hyperparathyroidism (NSH) in companion and stray cats of Ahvaz.   Design- Clinical study. Animals- 80 cats (companion=40 and stray=40) Procedures- This survey was accomplished during a two-year period and based on clinical, radiographic and laboratory findings between 2005 and 2007. The studied cats were divided into two gener...

The entry of calcium into dendritic spines can trigger a sequence of biochemical reactions that begins with the activation of calmodulin (CaM) and ends with long-term changes to synaptic strengths. The degree of activation of CaM can depend on highly local elevations in the concentration of calcium and the duration of transient increases in calcium concentration. Accurate measurement of these l...

Whole-cell calcium and barium currents were recorded from PC12 cell bodies and growth cones during nerve growth factor (NGF)-induced neurite outgrowth. Depolarizing voltage steps were applied to activate the currents, and pharmacological agents were used to separate them from other ionic currents. In recordings from growth cones still attached to neurites, current flow from central parts of the...

introduction: purkinje cell (pc) output displays a complex firing pattern consisting of high frequency sodium spikes and low frequency calcium spikes, and disruption in this firing behavior may contribute to cerebellar ataxia. riluzole, neuroprotective agent, has been demonstrated to have neuroprotective effects in cerebellar ataxia. here, the spectral analysis of pcs firing in control, 3-acety...

The insulin resistance syndrome, consisting of resistance to insulin and several metabolic abnormalities, is associated with an increased risk of symptomatic coronary artery disease. Asymptomatic persons with increased coronary calcification have increased coronary plaque and an increased likelihood of future cardiovascular events. Electron-beam computed tomography-derived coronary artery calci...

BACKGROUND AND OBJECTIVES Idiopathic hypercalciuria is a frequent defect in calcium kidney stone formers that is associated with high intestinal calcium absorption and osteopenia. Characteristics distinguishing hypercalciuric stone formers from hypercalciuric patients without kidney stone history (HNSFs) are unknown and were explored in our study. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS...
