حلقه های هتروسیکل هشت تایی ساده مثل 1، 3، 5 و -7تتراکسوکان دو صورت بندی قایق-صندلی (bc) و تاجی (crown) دارند. صورت بندی قایق-صندلی (bc) انرژی وارونگی حلقه متوسطی (حدود 33/5kj/mole) دارد. وارونگی حلقه صورت بندی های تاجی (crown) عموما از طریق تبدیلات درونی همراه با سد انرژی نسبتا بزرگتر (بیش از 50kj/mole) نسبت به قایق-صندلی که نسبتا به آسانی وارونه می شوند، انجام می گردد. مولکول 3 و -7بیس (m-نیتر...
The tegumental ultrastructure of juvenile and adult Himasthla alincia (Digenea: Echinostomatidae) was observed by scanning electron microscopy. One-, 5- (juveniles) and 20-day-old worms (adults) were harvested from chicks experimentally fed metacercariae from a bivalve, Mactra veneriformis. The juvenile worms were elongated and curved ventrally. The head crown bore 31 collar spines, arranged in...
Coleoid cephalopod molluscs comprise squid, cuttlefish and octopuses, and represent nearly the entire diversity of modern cephalopods. Sophisticated adaptations such as the use of colour for camouflage and communication, jet propulsion and the ink sac highlight the unique nature of the group. Despite these striking adaptations, there are clear parallels in ecology between coleoids and bony fish...
This cross-sectional study clinically assesses the tightness of proximal contact points of fixed dental prosthesis with natural teeth. Sixty nine (69) patients visiting the Department of Prosthodontics, Armed Forces Institute of Dentists (AFID), Rawalpindi, were included. The crowns, as a single unit or terminal abutment of bridge, prepared and fabricated at the same institute were included. A ...
The aim of the study was to determine the most common causes of root canal failure in patients who reported to the operative department of AFID( Armed forces institute of dentistry) for retreatment. This was a cross sectional study carried out at the operative department of AFID Rawalpindi from January 2011 to December 2012. Among 200 patients included in the study,112 (56 %) were male and 88(4...
The cercaria morphology of Echinochasmus japonicus was investigated using light and scanning electron microscopy. Cercariae, liberated from naturally infected snails (Parafossarulus manchouricus), had ovoid bodies and diminutive tails. The cercaria tegument was covered with minute spines. Four type II sensory papillae were observed on the dorsal side of the oral sucker, and type I papillae were...
