BACKGROUND This study aimed at investigating a potential effect caused by coccidia on the immune response to vaccine- and very virulent infectious bursal disease virus (vvIBDV) in SPF chickens. METHODS Two groups of three weeks old SPF chickens were vaccinated prior to inoculation with coccidia and challenge with virulent IBDV, all within a period of eight days. Two control groups were simila...

The quality of life can be improved and risk of fractures would be effectively reduced, by the proper initial diagnosis of the osteoporotic abnormality. The identification of low bone mineral density (BMD) or the onset of osteoporosis can be performed by means of detecting the extracted trabecular features from digital hip radiographs. The objective of our study was to apply a gradient based im...

This study evaluated a new body composition phantom and its use for quality control and cross-calibration of dual-energy X-ray absorptiometry (DXA) instruments for measurements of body composition. We imaged the variable composition phantom (Lunar, Madison, WI) on eight different DXA devices. Deviations of up to 7% fat were observed when we compared the percent fat values measured by the differ...

Orthodontic bands are retained on the crowns o f teeth by the luting action o f the cement. Studies by several work­ ers have demonstrated the inability o f zinc phosphate cements to produce an effective marginal seal and have shown microleakage to occur along the walls o f cavities restored with zinc phosphate cements. Differences in the coefficients o f thermal expansion between enamel, denta...

A marked reduction of 40-70% in regional bone mineral density (BMD) has been reported after fractures of long bones, and this post-traumatic osteopenia may to some extent persist for several years, perhaps lifelong. In this cross-sectional study, we investigated whether prolonged alcohol abuse had any effect on the degree of post-traumatic osteopenia after isolated tibia shaft fractures, the ra...

BACKGROUND Patients with cystic fibrosis (CF) have many risk factors for reduced bone mineral density (BMD). The aim of this study was to determine the prevalence of osteoporosis and osteopenia in a large cross section of patients and to identify risk factors. METHODS All patients attending the regional centre were invited to participate in the study. Bone mineral density was measured at the ...

Incorporation of a pH-sensitive conformational switch into a lipid structure enables a drastic conformational flip upon protonation that disrupts the liposome membrane and causes rapid release of cargo specifically in areas of increased acidity. pH-sensitive liposomes containing the amphiphile (1) with trans-2-morpholinocyclohexanol conformational switch, a phospholipid, and a PEG-lipid conjuga...

The effects of 13 soybean varieties (356, M4, M7, M9, Clark, Sahar, JK, BP, Williams, L17, Zane, Gorgan3, and DPX) on nutritional indices of the cotton bollworm, Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae), were determined at 25 ± 1° C, 65 ± 5% RH and a photoperiod of 16:8 L:D. Fourth instar larvae reared on Zane showed the highest efficiency of conversion of digested food (ECD) and ...

INTRODUCTION Maternal body composition (BC) changes during lactation. Increased prepregnancy obesity is associated with poor obstetric outcomes. The aim was to study changes in maternal BC postpartum (PP) to 1-year PP with reference to their prepregnancy body mass index (BMI) status. METHODS The study design was a 1-year follow-up study. Sixty-five apparently healthy primiparous women (28.6 ±...

OBJECTIVE The aim of this study is to determine the relation of osteoporosis and body mass index to edentulous jaw bone resorption. MATERIAL AND METHODS Study included 48 postmenopausal totally edentulous female patients, aged 50 to 84 years (average age 69.73), with period of at least 2 years after last tooth extraction. Bone mineral density was determined in the femoral neck and the lumbar ...
