statement of problem: glucocorticoid-induced osteoporosis is characterized by a decrease in osteoblast numbers and a marked impairment of new bone formation. purpose: the ain of present study was to evaluate the effect of methylprednisolone acetate on bone metabolism and bone mineral density in rats. materials and methods: eighteen male sprague dawley rats (8 weeks old, weighting 180 gm) were r...

BACKGROUND Fiducial markers are the superior method to compensate for interfractional motion in liver SBRT. However this method is invasive and thereby limits its application range. In this retrospective study, the compensation method for the interfractional motion using fiducial markers (gold standard) was compared to a new non-invasive approach, which does rely on the organ motion of the live...

conclusions exercise can improve anthropometric variables, body composition and vo2 peak and reduce some inflammatory markers in breast cancer survivors. objectives the current study aimed to investigate the effect of eight weeks of training on il-6, tnf-α and hcrp in postmenopausal breast cancer survivors. patients and methods twenty-seven postmenopausal breast cancer survivors with mean age o...

frequency of somaclonal variation in embryogenic calli and plants of olea europaea l cv.kroneiki derived from somatic embryogenesis were examined by randomly amplified polymorphic dna (rapd) analysis. radicle and cotyledon (proximal part) of mature zygotic embryo were cultured in omc medium supplemented with iba (5 mgl-1) and 2-ip (0.5 mgl-1). somatic embryogenesis was induced in calli of radic...

Four sampling schedules and three digesta markers were investigated with abomasally-cannulated steers. Nonammonia nitrogen flow through the abomasum was used as the criterion for comparison. A single diet, consisting of ground corn cobs and cane molasses and supplemented with soybean meal to 11.5% crude protein, was used. Each steer was fed hourly to maintain a constant digesta flow. Digesta ma...

The genetic structure of five Fennoscandian populations of the threatened wood-decay fungus Fomitopsis rosea (Basidiomycota) was investigated using codominant PCR-RFLP, allele specific amplification (ASA) markers, inter simple sequence repeat (ISSR) markers and mating studies. Sequence analyses of a subset of single spore isolates revealed sequence variation in four target sequences; internal t...

Measurement of ruminal microbial protein is necessary to quantify ruminal escape of dietary protein and microbial yields. Microbial markers used most widely have been the internal markers, diaminopimelic acid and nucleic acids (RNA, DNA, individual purines and pyrimidines, or total purines), and the external isotopic markers (e.g., 15N and 35S). Combined with digesta flow markers in ruminally a...

Due to respiration, many tumours in the thorax and abdomen may move as much as 3 cm peak-to-peak during radiation treatment. To mitigate motion-induced irradiation of normal lung tissue, clinics have employed external markers to gate the treatment beam. This technique assumes that the correlation between the external surface and the internal tumour position remains constant inter-fractionally a...
