Reduced anti-Miillerian hormone [AMH] in mares with hemorrhagic anovulatory follicles

Anti-Miillerian hormone [AMH] has been observed to decrease with the development of hemorrhagic anovulatory follicles [HAFs] in mares. Two studies were conducted to evaluate AMH concentration in mares with HAFs compared to seasonally anoestrous and cyclic mares, and to elucidate changes of AMH with the development of luteinised unruptured follicles [LUFs]. In study 1, AMH and progesterone were evaluated in seasonally anoestrous, anovulatory [with HAF] and cyclic mares [at mid luteal phase]. In study 2, mares in control and LUF groups were treated with 1500 IU/case hCG when they had a >/=32-mm follicle and an endometrial oedema score of three [day 0]. Mares in the control group received no further treatment. Mares in the LUF group received 1.7 mg/kg flunixin meglumine at the time of hCG administration, and 12, 24 and 36 h after it. Ultrasonography and blood collection for AMH and progesterone measurement were performed on days 0, 1, 2, 4, 6 and 8. In study 1, AMH concentration was lower in seasonally anoestrous and HAF mares than cyclic mares [P<0.05]. Progesterone concentration did not differ between HAF and cyclic mares [P>0.05]. In study 2, AMH was not different between LUF and control mares [P>0.05]; however, progesterone had a lower concentration and a delayed rise after hCG administration in LUF mares compared with the control group [P<0.05]. The results indicated that similar to seasonally anoestrous mares, AMH concentrations decreased in mares with HAFs. LUFs were also found to be functionally different from HAFs

[Study the vulnerability of urban furniture in an earthquake Case study: [Hafte Tir SQ- Blv. Keshavarz]]

Background: the used equipment in streets or urban furniture is the most important components of the cities. This paper aims to identify the weak and strength points of urban furniture not only in designing, building and positioning but also its influence on disasters increase after an earthquake

Methods: this research has studied the vulnerability of the mentioned components based on current standards. In order to study all current standards of urban furniture and comparing them with the current status, the district 6 of Tehran city [Hafte Tir SQ - Blv. Keshavarz], as a case study, was selected

Findings: regarding to the studied standards in this research, some necessary safety points are ignored in urban furniture such as place and way of installation, structural resistance and availability

Conclusion: there is not any suitable regulation and standard in the field of urban furniture in Tehran in spite of compiling the structure standards and urban furniture design
