the objective of the present study was to investigate the effects of a sustained-release multi-trace element ruminal bolus on sex ratio, the reproductive performance and lambs growth of afshari ewes. eighty afshari cycling ewes during breeding season were used in the trial. the animals were synchronized using cidr for 14 days and assigned into 4 groups including: group 1 (n=20) received a singl...

published data on the effects of ruminal bolus on the number of ovulatory follicles in ewes does not exist. the present study determined the effects of a ruminal bolus on trace element status, follicular dynamics and reproductive performance in ewes. eighty afshari cycling ewes were synchronized during breeding season using cidr for 14 days and assigned to 4 groups (n=20); group 1 received a si...

The dynamics of a bolus transport through the esophagus are largely unexplored. To study this physiological process, we applied multiple intraluminal impedancometry in 10 healthy subjects. Three different protocols were used: 1) liquid bolus administered with subject supine, 2) liquid bolus with subject upright, or 3) semisolid bolus with subject supine. Transit of different parts of a bolus (b...

Introduction Bolus is a soft and resilient material which is used for increasing skin dose or to even out the irregular patient contour. The main property of various materials used presently as bolus is the water-equivalent electron density. Ethyl methacrylate is used as a soft-liner in dentistry and its physical and chemical properties are proved to be nontoxic for human body. The goal of this...

Introduction: The objective of this study was to describe the modalities responses observed following realization a bolus methylprednisolone in children treated for nephrotic syndrome pediatric nephrology unit Abidjan order assess need its our practice. Methods: we carried out descriptive and analytical cross-sectional patients followed up having benefited from administration 3 boluses at dosag...

Introduction: The present study aimed to generate intensity-modulated beams with Aluminium compensating filters for a conventional telecobalt machine based on the outputs of a treatment planning system (TPS) performing forward planning and cannot simulate directly the compensating filter. Materials and Methods: In order to achieve the beam intensity modulation during treatment planning with th...

PURPOSE To assess the quality of the arterial input function (AIF) reconstructed using a dedicated pre-bolus low-dose contrast material injection imaged with a high temporal resolution and the resulting estimated liver perfusion parameters. MATERIALS AND METHODS In this IRB-approved prospective study, 24 DCE-MRI examinations were performed in 21 patients with liver disease (M/F 17/4, mean age...
