| March 2014 | 286 L E T T E R T O E D IT O R Since, emergent interventions might be necessary in cases with a history of epileptic seizures,[5] general anesthesia was selected for this patient. Titrated calcium replacement therapy is recommended by monitoring ionized calcium levels, since calcium takes part in muscle contractions-relaxations.[6] Although, hypocalcemia aff ects neuromuscular ag...

ADP plays a key role in hemostasis and thrombosis. Despite its early identification in 1961 as the first known aggregating agent, the molecular basis of ADP-induced platelet activation is only beginning to be understood. The present review proposes a model of 3 purinergic receptors contributing separately to the complex process of ADP-induced platelet aggregation: the P2X(1) ionotropic receptor...

This study was designed to validate the utility of a commercial portable clinical blood analyzer (PCBA) in ground-based studies and on the space shuttle. Ionized calcium, pH, electrolytes, glucose, and hematocrit were determined. Results agreed well with those from traditional laboratory methods, and the PCBA demonstrated good between-day precision for all analytes. In-flight analysis of contro...

There is growing evidence that cell cleavage involves contraction in the region of the furrow and relaxation above the most distant parts of the spindle (see references 15 and 16) . The contractile mechanism has been likened to that of muscle, mainly as a result of studies of glycerinated models of dividing cells (7, 9) and extraction of an actomyosin-like material (8, 11) . Muscular contractio...

Homeostatic control of ionized calcium can be volatile during liver transplantation, particularly during the anhepatic stage. Recently, an opportunity arose to evaluate an 11-year-old girl who developed persistent ionic hypocalcemia during a prolonged anhepatic period subsequent to the failure and removal of the graft. The patient was remarkable for having survived a 34-hour anhepatic interval ...

OBJECTIVES Because biological data are instrument-dependent and because technology has evolved over the last two decades, the published capillary blood reference values for blood gases, lactate, ionized calcium (iCa) and glucose may not reflect the present day situation. Hence, we report such values for healthy term neonates at 48 +/- 12 h of life. DESIGN AND METHODS The Institution Ethics Re...

OBJECTIVE The aim of this retrospective longitudinal naturalistic study was to evaluate the effects of maintenance lithium treatment on parathyroid hormone (PTH) and calcium levels. METHODS A retrospective longitudinal naturalistic study design was used. Data were collected from the database of a tertiary psychiatric center covering the years 2010-2014. Included were bipolar patients who had ...

AIM To examine the calcium metabolism of colorectal cancer (CRC) in patients with colorectal cancer and control patients. METHODS Seventy newly diagnosed CRC patients were included. The healthy control group was age and gender matched (n=32). Particular attention was devoted to the relationship between serum calcium of patients, and levels of AFP, CEA, carbohydrate antigen 19-9 (CA 19-9) (tha...

A total of approximately 1-1.5kg of body weight is made up of calcium where 99% is found in the bones and teeth and remaining 1% is in the ECF and other compartments. Ca exists as carbonates or phosphates of calcium within the body, while in the plasma they exist in either the ionized form(which is the physiologically active form), bound to plasma proteins(mainly albumin) or complexes with orga...

Thirteen patients with mild primary hyperparathyroidism who were taking thiazide diuretics intermittently for periods of up to 18 months were followed up for a mean of 5.3 years. No significant difference was found in either plasma total calcium corrected for albumin or whole blood ionized calcium in these patients between the periods on or off thiazides. We conclude that thiazide diuretics are...
