objective: the objective of this study was to investigate the invitro fluoride release of four new self-adhesive resin cements; set (sdi, australia), breeze (pentron, usa), embrace wetbond (pulpdent, usa), g-cem (gc, japan) and to assess the bonding performance of these self-adhesive resin cements for bonding of orthodontic brackets. materials and methods: for fluoride release experiment, six ...
In the first experiment, osmotic pressure of semen and seminal plasma in a semen sample from each of the 20 mature Nili-Ravi buffalo bulls was determined. In the second experiment, effects of osmotic pressure on motility (%), plasma membrane integrity (%) and viability (%) in fresh and frozen-thawed semen samples from each of the seven mature Nili-Ravi buffalo bulls was determined. In the first...
this study investigated the impact of explicit instruction of morphemic analysis and synthesis on the vocabulary development of the students. the participants were 90 junior high school students divided into two experimental groups and one control group. morphological awareness techniques (analysis/synthesis) and conventional techniques were used to teach vocabulary in the experimental groups a...
this study was undertaken to compare the efficiency of fresh and frozen-thawed buck semen on in vitro fertilization (ivf) of goat oocytes. cumulus oocytes complexes (cocs) were collected by aspiration of 2-6 mm diameter follicles, which were obtained from slaughterhouse. upon grading, only normal quality cocs were maturated in tcm-199 for 48 hours. the percentage of cocs reached to the m-ii sta...

BACKGROUND Artificial insemination (AI) using frozen-thawed semen is well established and routinely used for breeding in various mammalian species. However, there is no report of the birth of elephant calves following AI with frozen-thawed semen. The objective of the present study was to investigate the fertilizing ability of chilled and frozen-thawed semen in the Asian elephant following artif...
in this study, the effects of oleothermal modification on physical and mechanical peroperties of fir wood (abeis sp.) blocks were examined. at first, some blocks of fir wood with 5 × 20 × 120 cm dimensions were prepared. the blocks were treated in soybean oil. the effects of 3 factors such as treatments temperature (180and 200 °c), holding time (12 and 15 h) and initial moisture content of wood...
This study was conducted to assess the post thaw quality of Kundhi buffalo semen diluted in tris based diluents. After collection the ejaculates were pooled and checked for color, volume, pH, mass activity, progressive linear motility% (PLM), and intactness of cell membrane. The semen qualifying these tests was divided into four aliquots A, B, C and D, diluted with tris based diluents; the last...
The aim of the present study was to investigate the effect of in vitro supplementation of selenium on fresh and frozen spermatozoa quality of buffalo (Bubalus bubalis) bulls. Five healthy buffalo bulls (5 ejaculates from each bull) were used. Each ejaculate was diluted at 37 ˚C with tris-based extender containing 0 (control), 0.5, 1, 2, 4 and 8 μg mL-1 sodium selenite and the sperm motility and...
Aim: The aim was to determine the antioxidative capacity of vitamin E, vitamin C and their combination (vitamin E+C) on standard semen parameters i.e., mortality, percent live sperms, percent abnormal sperms and acrosomal integrity in cryopreserved Bhadawari bull semen. Materials and Methods: Ejaculates collected from four Bhadawari bulls were evaluated and later pooled at 37°C. Pooled semen sa...
