Responses of Sri Lankan indigenous goats and their Jamnapari crosses to artificial challenge with Haemonchus contortus.

Goat farming plays an important role in the Sri Lankan rural economy. Sri Lankan indigenous (SLI) goats and their crossbreds are reared mainly under extensive management and indiscriminately exposed to pathogens and parasites. This study was designed to evaluate resistance to haemonchosis in SLI goats and their Jamnapari crossbreds (JCB) in the dry zone of Sri Lanka.

Image-guided radiotherapy for prostate cancer in the United Kingdom: a national survey.

Objective: To survey the technology and practice of image-guided radiotherapy (IGRT) for prostate cancer in the UK.

Methods: A pre-tested semi-structured online questionnaire was sent to National Health Service (NHS) and private radiotherapy providers in the UK between March and April 2014. The survey was carried out on the Opinio online platform.

Image-guided radiotherapy for prostate cancer with cone beam CT: dosimetric effects of imaging frequency and PTV margin.

Background And Purpose: This study assesses the effect of frequency of cone beam CT (CBCT) verification imaging on dose-volume parameters during image-guided radiotherapy (IGRT) for prostate cancer. It also investigates the dosimetric impact of reducing the planning target volume (PTV) margin, when daily imaging is used.

Material And Methods: 844 CBCT images from 20 patients undergoing radical prostate radiotherapy were included.

Obstetric performance of women who have previously delivered a baby of low birthweight.

Objectives: To investigate pregnancy outcomes in women who have previously given birth to a baby weighing less than 2500 grams in a population in which the low birthweight rate is high.

Methods: We compared the obstetric performance of 100 women who had delivered a low birthweight baby (<2500g) at term in a previous pregnancy (cases) with those of 100 women who were matched for age, height, body mass index at booking, parity and medical disorders, who had previously delivered a baby above that threshold (controls).

Results: We found the following significant differences between cases and controls (p<0.

Thyroid hormone and anti-Mullerian hormone (AMH) on Leydig cell differentiation: studies using C57BL/6 mice and AMH over expressing mice.

Although the thyroid hormone has stimulatory effects and anti-Mullerian hormone (AMH) has inhibitory effects on prepubertal Leydig cell (LC) differentiation, it is important to find out whether the stimulatory effect of thyroid hormone could overcome the inhibitory effect of AMH on postnatal LC differentiation. Therefore, the objective of the present study was to use the anti-Mullerian hormone overexpressing mouse (AMH++) model to understand the simultaneous effects of AMH and thyroid hormone on postnatal LC differentiation, proliferation, maturation and function and to test whether the inhibitory effect of AMH could be overcome by the stimulatory effect of the thyroid hormone. Four age groups (7, 21, 40, 90 days) of control (C57BL/6; C) and AMH++ were used.
