The intravenous administration of griseofulvin in doses of 3.0 mg/kg to 32 anesthetized open-chest dogs produced marked increments (43%) in isometric systolic force measured by a strain gauge. These changes were accompanied by an increase (22%) in heart rate and a decrease (25%) in blood pressure. The effect was unaltered by clamping the blood supply to and from the adrenal glands or by previou...

The optimal time for umbilical cord clamping after birth remains a critical unknown fact that has implications for the infant, the mother, and science. A national survey was conducted using a randomized sample (n = 303) of the active membership of the ACNM to determine cord clamping practices and beliefs of American nurse-midwives. The response rate was 56%. The respondents fell into three cord...

BACKGROUND Recent experimental physiology data and a large, population-based observational study have changed umbilical cord clamping from a strictly time-based construct to a more complex equilibrium involving circulatory changes and the onset of respirations in the newly born infant. However, available evidence is not yet sufficient to optimize the management of umbilical cord clamping. FIN...

This study was conducted to evaluate the haematological effects of the timing of umbilical cord clamping in term infants 24 h after birth in Libya. Mother-infant pairs were randomly assigned to early cord clamping (within 10s after delivery) or delayed clamping (after the cord stopped pulsating). Maternal haematological status was assessed on admission in the delivery room. Infant haematologica...

In many constructions, their elements are in contact with nominally matching (congruent) surfaces. reality, this is disturbed due to deviations the shape of these surfaces from nominal. To study effect perturbation on distribution pressure, analysis stress-strain state body system punched sheet-die carried out. The middle element deviates flat shape. This causes a change pressure distribution. ...

<p>The heart of the machining center design is spindle design, and one primary functions in a tool clamping system mechanism. The selection disc spring stack for mechanism an iterative process that highly depends on space availability, drawbar unclamp stroke length, standard force requirements. For example, even 0.1 mm may impact kN depending design. Hence time- intensive also needed care...

This paper mainly examines the fixation performances of cephalomedullary nail for incidence intertrochanteric (IT) fracture to guide appropriate fixations with respect bone density in terms a biomechanical perspective. It is substantially important which types are applied during operation since it tends induce backout or migration helical blade and screw according weight density. Biomedical pol...

Over the past 40 years, there have been a number of review articles attempting to rationalise cord clamping practice. Early cord clamping was originally thought to be important in active management of the third stage of labour, but this was never evidence based. Without an evidence base to justify it, early cord clamping in clinical practice has remained very variable. There is good evidence th...

Objective: Prompt bleeding control with proximal aortic clamping and subsequent aortic repair are very important for ruptured abdominal aortic aneurysm. However, unsuitable anatomy, such as short aortic neck length, not only disturbs the means to an expeditious repair, but may also increase morbidity and mortality. In the present study, we aimed to evaluate the efficacy of supraceliac aortic cl...
