We investigated which activity of myosin B (natural actomyosin), super-precipitation or ATPase, is better suited as a parameter for measuring in vitro contraction with emphasis on the response of myosin B to Sr2+. The Sr2+ concentration giving half-maximum (KSr2+) binding of Sr2+ to cardiac troponin was not different from that to skeletal troponin, whether the troponins were contained in the ac...

Abstrak. Infiltrasi tanah adalah proses masuknya air secara vertikal ke dalam melalui permukaan tanah. Proses infiltrasi dapat membantu memenuhi kebetuhan terhadap dan mengurangi terjadinya erosi banjir. dipengaruhi oleh beberapa sifat yaitu tekstur tanah, C-organik, porositas, bulk density, permeabilitas kemantapan agregat. Penelitian ini dilakukan di Kecamatan Lhoksukon Kabupaten Aceh Utara p...

Hormones and neurotransmitters that act through inositol 1,4,5-trisphosphate (IP3) can induce oscillations of cytosolic Ca2+ ([Ca2+]c), which render dynamic regulation of intracellular targets. Imaging of fluorescent Ca2+ indicators located within intracellular Ca2+ stores was used to monitor IP3 receptor channel (IP3R) function and to demonstrate that IP3-dependent oscillations of Ca2+ release...

PEDF (Pigment epithelium-derived factor) is a non-inhibitory member of the serpin gene family (serpinF1) that displays neurotrophic and anti-angiogenic properties. PEDF contains a secretion signal sequence, but although originally regarded as a secreted extracellular protein, endogenous PEDF is found in the cytoplasm and nucleus of several mammalian cell types. In this study we employed a yeast...

The conduction properties of the alkaline earth divalent cations were determined in the purified sheep cardiac sarcoplasmic reticulum ryanodine receptor channel after reconstitution into planar phospholipid bilayers. Under bi-ionic conditions there was little difference in permeability among Ba2+, Ca2+, Sr2+, and Mg2+. However, there was a significant difference between the divalent cations and...

ABSTRACT The stability constants of ML-type complexes of the two linear triphosphate ligand anion analogues triphosphate ([Formula: see text]) and diimidotriphosphate ([Formula: see text]) were investigated thermodynamically using potentiometric titrations according to Schwarzenbach's procedure. The stability constants of the ML-type complexes of different divalent metal ions with [Formula: see...

Our previous studies have indicated the presence of a macromolecular inhibitor of in vitro mineral growth, as well as a mineral nucleational agent in extracellular matrix fluid aspirated by micropuncture methods from epiphyseal hypertrophic cell cartilage. In this report, new miniaturized methods were used to extract proteinpolysaccharide complexes (PPC) from cartilage, to isolate a light fract...

To develop a live vaccine strain against fowl typhoid and paratyphoid caused by Salmonella serovar Gallinarum biovar Gallinarum (Salmonella Gallinarum) and Salmonella serovar Enteritidis (Salmonella Enteritidis), respectively, several nalidixic acid resistant mutants were selected from lipopolysaccharide (LPS) rough strains of Salmonella Gallinarum that escaped from fatal infection of a LPS-bin...

High quality large Bi2(Sr2−xLax)CuO6+δ (La-Bi2201) single crystals have been successfully grown by the traveling solvent floating zone technique. The samples are characterized by compositional and structural analyzes and their physical properties are investigated by magnetic susceptibility and resistivity measurements. Superconducting samples with sharp superconducting transitions are obtained ...

This paper presents the sensor and control system for SR2, a planetary rover prototype capable of km+/day traverses through Mars-like terrain. The control system described allowed the rover to successfully navigate Mars-like terrain given a set of waypoints spaced approximately 100m apart. The control system uses input from a variety of sensors including heading, roll, pitch, an array of proxim...
