background:  due to difficulty in obtaining anatomical reduction, management of the unstable intertrochanteric fractures in elderly osteoporotic patients is challenging. the purpose of this study is to compare the results of hip arthroplasty (total, hemi, or bipolar) with dhs in the elderly patients with unstable intertrochanteric fractures.   methods:  we prospectively studied and followed-up ...

introduction: the aim of this in vitro study was to compare the effect of hand and rotary instruments on fracture strength of tooth roots. materials & methods: thirty two teeth were randomly divided into two experimental groups of 15 each and one negative control group with two samples. in group 1, step-back technique with conventional stainless steel k-files was used, and in group 2, instrumen...

cattle syndrome absent in MKs from CHS cattle at all stages of maturation. MKs in bone marrow samples from two control (n = 91) five and two CHS (n = 61 ) cattle that had been processed for were the uranaffin reaction were also evaluated. The clear microsvesicles were replaced by uranaffin-positive granules in in MKs from control cattle. but positive uranaffin granules clear were not observed i...

In 2000 and 2003, two massive hydraulic fracturing experiments were carried out at the European Geothermal Hot Dry Rock site at Soultz-sous-Forêts, France. The objective was to create a dense network of enhanced permeability fractures, which would form the heat exchanger. The injection of water in the fractured rock generated a high level of microseismic activity: around 30,000 and 90,000 micro...

OBJECTIVES To review the history, theory and current applications of Weibull analyses sufficient to make informed decisions regarding practical use of the analysis in dental material strength testing. DATA References are made to examples in the engineering and dental literature, but this paper also includes illustrative analyses of Weibull plots, fractographic interpretations, and Weibull dis...

part of the body to the innominate bones. The sacrum also conducts the sacral nerve roots to the pelvic organs. Each innominate bone is a fusion of the ilium, ischium, and pubic bones. The intersection of the fusion forms the acetabulum, which articulates with the femur. Posteriorly, the innominate bones are anchored to the sacrum by the anterior and posterior iliac ligaments, two of the body’s...

Fractures of the rostral mandible in horses are the most common type of jaw fractures. The present study was performed for stabilization of rostral mandibular fracture with cerclage wire. In a retrospective case series, six client-owned horses with unilateral mandibular fractures were admitted to our clinic and suffered from a major gingival wound at rostral part of mandible. Rostral mandibular...

Progress.?The wound went on discharging much as before, but about three weeks later much pain being complained of, it was found that the femur had spontaneously fractured. Operation.?After a delay of some weeks, owing to the unwillingness of the patient, the thigh was amputated at the middle about 3 inches above the seat of fracture. The operation was performed under the spray, and subsequently...

In the outer plexiform layer of the retina the synaptic endings of cone cells make specialized junctions with each other and with the endings of rod cells. The ultrastructure of these interreceptor junctions is described in retinas of monkeys, rabbits, and turtles, in thin sections of embedded specimens and by the freeze-fracturing technique. Cone-to-rod junctions are ribbon-like areas of close...
