The primary aim of this study is to determine maximum bite force in molar and incisor regions of healthy individuals, to evaluate the bite force after open reduction and internal fixation of mandibular fractures using micro plates, for a period of up to 6 weeks and to determine the rate of recovery of maximum bite force in an Indian population.

OBJECTIVES The aim of this study is to investigate the efficacy of fibula fixation in the early treatment of osteonecrosis of the femoral head (ONFH). METHODS 130 patients with ONFH were selected and randomly divided into control group and observation group. Patients in the control group received core decompression treatment, while patients in the observation group received fibula fixation. T...

CONCLUSION: We could achieve complete bone healing and premorbid occlusion using microplates. The microplates are strong enough to keep comminuted mandibular fractures reduced. Their small size and malleability allow multiple fixation of comminuted bony segments in accurate-anatomical position, less periosteal stripping and self-occlusal adjustment. Therefore, microplate fixation may be one of ...

On the contrast to the well known, that there are other different genes involved in symbiotic nitrogen fixation in addition to nod, nif and fix genes. In this review we will discuss up to date the function of genes that can play a significant role in symbiotic N fixation such as nodulation, nitrogen fixation, production of 2 exopolysaccharides, Type I to Type VI secretion systems and other diff...

THE treatment of amblyopia and eccentric fixation is said to be associated with special problems. In some centres pleoptics have been used, but the need for trained staff and special equipment can pose difficult problems. The harmful effects of conventional occlusion of the fixing eye have been stressed by Arruga (1962). Recently, Brinker and Katz (1963) have drawn attention to the fact that, a...

BACKGROUND To study the rarity of mandibular coronoid process fractures and treatment strategies based on the displacement of these fractures. MATERIALS AND METHODS A retrospective study of 11 cases of coronoid process fractures among 307 treated cases from 2008 to 2013 was conducted. Six patients were treated conservatively and 5 underwent ORIF with associated fractures. A statistical analys...

In temperate Atlantic waters (18.8 to 20.1°C), biological nitrogen fixation has been demonstrated by 2 independent measurements: N-N2 incorporation and nifH identification in the DNA and expressed messenger RNA (mRNA). At 2 stations in the western English Channel, bulk waters were incubated with N-N2. At the high levels of particulate nitrogen (≤11.5 μmol N l–1), absolute fixation rates of 18.9...

OBJECTIVES To document the refracture rate after removal of internal fixation at the metaphyseal region of the distal radius and to compare this rate to that associated with diaphyseal plate removal reported in the literature. DESIGN A chart review with telephone follow-up. SETTING Three tertiary care hospitals (in Ottawa, Burlington, Vt., and London, Ont.). PATIENTS Fifty-three patients ...

The treatment of hip fractures in the elderly represents a major public health priority and a source of ongoing debate among orthopaedic surgeons and anesthesiologists. Most of these injuries are treated with surgery in an expedient fashion. From the surgical perspective, there are certain special considerations in this population including osteoporosis, pre-existing arthritis, age, activity le...

We examined rates of N2 fixation from the surface to 2000 m depth in the Eastern Tropical South Pacific (ETSP) during El Niño (2010) and La Niña (2011). Replicated vertical profiles performed under oxygen-free conditions show that N2 fixation takes place both in euphotic and aphotic waters, with rates reaching 155 to 509 µmol N m(-2) d(-1) in 2010 and 24±14 to 118±87 µmol N m(-2) d(-1) in 2011....
