In vitro effect of cadmium on vitamin D-stimulated calcium transport in the rat was studied using the everted gut sac technique. Calcium transport was significantly inhibited by the addition of cadmium to the mucosal incubation medium. Furthermore, the kinetic analysis of inhibitory effect of cadmium on calcium transport revealed that the type of inhibition was competitive. The apparent "Km" and "Vmax" value for calcium was 1.0 mM, and 2.86 mumoles ml-1.hr-1, respectively. An apparent "Ki" for cadmium ...

A γ-carboxyglutamic acid (Gla)-containing protein was purified from rat femur cortical bone. The presence of 4 Gla residues in the rat protein was shown by amino acid analysis on alkaline and acid hydrolysates. The protein was extracted from rat cortical bone with 0.5 M EDTA (pH 7.6) and purified from the EDTA extracts by gel filtration on Sephadex G-100 and ion-exchange chromatography on DEAE-Sephadex A-25. The protein has a molecular weight of about 6, 000 on the basis of amino acid composition. ...

A new protein has been isolated from CaCl2/urea extracts of demineralized bovine bone matrix. This protein has five to six residues of the vitamin K-dependent amino acid, gamma-carboxyglutamic acid (Gla), and we have accordingly designated it matrix Gla protein. Matrix Gla protein is a 15,000 dalton protein whose amino acid composition includes a single disulfide bond. The absence of 4-hydroxyproline in matrix Gla protein demonstrates that it is not a precursor to bone Gla protein, 5,800 dalton protein ...

A marked dissociation has been observed between the timed accumulation in calcified tissues of two related vitamin K-dependent proteins, bone Gla protein (BGP) and the recently discovered matrix Gla protein (MGP). In long bone diaphyses, total levels of MGP were essentially equivalent in newborn, juvenile, and adult rats. In agreement with previous studies, BGP levels were only 5% of adult levels in newborn rat bones and increased to 90% of adult levels by 19 days of age. Similar results were obtained ...

A complex of the α‐ and β‐subunits of thermophilic ATP synthase showed about 25% of the ATPase activity of the αβγ complex. The α 3 β 3 hexamer structure was analyzed by sedimentation (11.2 S) and gel filtration (310 kDa). Dilution of the αβ complex caused dissociation of the complex and rapid loss of ATPase activity which was restored by addition of the γ‐subunit. A previous method using urea for isolating the subunits resulted in an αβ complex with lower activity than that prepared by over‐expression ...

Several clonal rat osteosarcoma cell lines were tested for the ability to express and secrete matrix Gla protein (MGP), a small vitamin K-dependent protein found in bone and cartilage. Two independently derived cell lines, UMR 106-01 and ROS 25/1, expressed MGP mRNA and secreted MGP antigen identical in size with that found in bone. No MGP message could be detected in ROS 17/2 and 2/3 cells, cell lines previously shown to synthesize the other known vitamin K-dependent bone protein, bone Gla protein ( ...

The primary structures of all the subunits of thermophilic ATP synthase were determined, and its α, β and γ subunits could be over-expressed in Escherichia coli, because these subunits were stable and reconstitutable. DNA of 7500 base pairs in length was found to contain a cluster of nine genes for subunits of ATP synthase. The order of their reading frames (size in base pairs) was: I(381):a(630):c(216):b(489):δ(537):α(1507):γ(858):β(1419):ϵ(396), I being a gene for a small hydrophobic, basic protein ...

Cerebral hyperperfusion after carotid endarterectomy (CEA) occurs in patients with preoperative impairments in cerebral hemodynamics. Signal intensity of the middle cerebral artery (MCA) on single-slab 3-dimensional time-of-flight magnetic resonance angiography (MRA) can assess hemodynamic impairment in the cerebral hemisphere. The purpose of the present study was to determine whether the signal intensity of the MCA on preoperative MRA could identify patients at risk for cerebral hyperperfusion after ...

Patients with SAH often experience cognitive decline. Previous studies used normal volunteers, published normal test values, and orthopedic patients as controls to identify factors for postoperative cognitive decline. The present study excluded the effects of surgery by comparing cognitive function after surgical repair in patients with aneurysmal SAH and patients with unruptured intracranial aneurysm.This study recruited 117 patients with SAH due to ruptured aneurysm and 39 patients with incidentally ...

A coupled vibrating system (for example turbine-generator set), consisting of a main system (for example shaft system) and a sub-system (for example blade system) which are connected at bonding points (for example the centre boss of a blade), is equivalently reduced to a model suitable for analysis. According to this modelling technique, the eigenvalue analysis of the uncoupled flexible sub-system is done first under the assumption of the fixed bonding point. Then, an equivalent mass-spring system is ...

Heat shock proteins 60 (hsp60) and 10 (hsp10) are essential for the formation and restoration of many supramolecular structures. For reconstitution of these structures, we isolated stable hsps of 61kDa and 12kDa, which are similar to hsp60 and hsp10, respectively, from the supernatant fraction of thermophilic bacterium PS3 by ATP-Agarose chromatography. Using synthetic DNA of the deduced sequence, the 1.6kbp double stranded DNA encoding both proteins was obtained by the polymerase chain reaction (PCR). ...

Non-linear hydrodynamic behavior of bubble motion and that of particle motion in a three-phase fluidized bed have been modeled by resorting to an artificial neural network (ANN). The experiments were performed in a transparent acrylic resin column with an inner diameter of 0.184 m and a height of 2.0 m. Subsequently, the ANN was trained with the time-series data comprising temporal intervals, each of which was the period between two sequential signals of bubbles or particles from an optical transmittance ...

Abstract OBJECTIVE Multislice computed tomographic angiography (CTA) can provide clearer vascular images, even of the peripheral arteries, than conventional CTA. Multislice CTA was compared with digital subtraction angiography (DSA) for the detection of cerebral vasospasm in patients with acute aneurysmal subarachnoid hemorrhage (SAH) to analyze whether multislice CTA can replace DSA in the detection of vasospasm after SAH. METHODS Within 72 hours after the onset of symptoms, multislice CTA and DSA ...

Instantaneous local heat transfer rates were measured by using a hot-wire probe in three bubble columns of different diameters of 200, 400 and 800 mm. The time series of heat transfer rates were analyzed by means of rescaled range (R/S) and deterministic chaos analyses. Due to the influence of highly chaotic bubble motions, the instantaneous local heat transfer exhibits low-dimensional chaotic features. The dependences of Hurst exponents and Kolmogorov entropy on the column scale consistently suggest ...

The significance of brain temperature (BT) in patients with severe brain damage remains unclear. This study investigated the relationships between BT, systemic temperature (ST), and clinical outcome in patients with severe subarachnoid hemorrhage. Thirty-one comatose patients with severe subarachnoid hemorrhage underwent ventricular drainage immediately after admission. The ventricular catheter also allowed monitoring of BT. ST was continuously measured using a bladder catheter with thermistor probe. ...
