The conditions that permit the interaction of immediate-early proteins of murine cytomegalovirus (MCMV) with DNA were studied. Chromatography of extracts from infected cells on MCMV DNA cellulose and calf thymus DNA cellulose showed that pp89, the regulatory major immediate-early protein, interacts with DNA and dissociates at salt concentrations between 0.3 and 0.6 M NaCl. pp76, a cleavage prod...

An experimental program to determine t ie pi-enomenological aspects of composite-panel failure under simultaneous compressive n-plane loading and low-velocity transverse impact [C-75 m/s (0-250 ftls)] is described. Highspeed photograohy coupled with the shadow-moire techniq~e is usec to record the phenomenon of failure propagatior. The informat on gained from these records, supplemented by plat...

Abstract This research investigates the effect of Schiff base, namely, N' -[4-(dimethylamino) benzylidene]-4-hydroxybenzohydrazide (SB) on corrosion mitigation mild steel (MS) in hydrochloric acid medium (HCl) using potentiodynamic polarization (PDP) technique. The study highlights SB concentration, HCl and temperature current density ( i corr ) inhibition efficiency (IE). adsorption onto MS su...

Abstract Background Patients with injection drug use (IDU) have increased risk of developing infective endocarditis (IE). Previous studies reported recurrent IE, duration hospital stay, poor adherence and compliance as well higher mortality worse outcomes after surgery in the IDU-IE patient group. Further are needed to provide a basis for optimized care prevention readmissions this population. ...

Abstract The effect of an aromatic hydrazide derivative 4-hydroxyl-N′-[(3-hydroxy-4-methoxyphenyl) methylidene] benzohydrazide] (HMBH) as inhibitor for the corrosion carbon steel in 0.5 M H 2 SO 4 solution was investigated temperature range 303 K to 323 using potentiodynamic polarization (PDP) and electrochemical impedance spectroscopy (EIS). concentration HMBH used 0.1 1 mM. Inhibition efficie...

The present study was carried out to characterize the cervical mucus (CM) collected when inseminating Holstein cows and to relate the secretion pattern with pregnancy. The mucus was collected from mid-cervix of 64 cows with spontaneus estrus (SE) and induced estrus (IE). The quantity, pattern and consistency of the mucus, pH, arborization patterns and the sperm motility were observed. The level...
