INTRODUCTION Rhegmatogenous retinal detachment (RRD) is the most common form of retinal detachment, where a retinal "break" allows the ingress of fluid from the vitreous cavity to the subretinal space, resulting in retinal separation. It occurs in about 1 in 10,000 people a year. METHODS AND OUTCOMES We conducted a systematic review and aimed to answer the following clinical questions: What a...

In reporting on the theorem prover SCOTT (Slaney, SCOTT: A Semantically Guided Theorem Prover, Proc. IJCAI, 1993) we suggested semantic constraint as as an appropriate mechanism for guiding proof searches in propositional systems where the rule of inference is condensed detachment|a generalisation of Modus Ponens. Such constrained condensed detachment is closely analogous to semantic resolution...

OBJECTIVES To assess the frequency of retinal detachment following postcataract endophthalmitis and to evaluate the results of management of these detachments. METHODS Prospective data collected as part of the Endophthalmitis Vitrectomy Study were analyzed. The study was a randomized clinical trial testing the roles of vitrectomy and intravenous antibiotics in restoring vision in patients wit...

A mechanics-based mathematical model for retinal detachment is developed, incorporating an energy-based criterion for propagation. Retinas with and without central tears are considered and contraction of the vitreous and extension of its fibrils, along with a pressure difference across the retina, are taken as the stimuli for detachment propagation. In addition to the equations of motion, bound...

AIM To establish whether the presence of a retinal break can be predicted either by the presence of a positive Shafer's sign (pigment granules in the anterior vitreous) or symptomatology in patients presenting with an acute posterior vitreous detachment (PVD). METHODS 200 eyes of 200 phakic patients with a symptomatic PVD of less than 1 month's duration underwent documentation of symptomatolo...

Spatial and short-term temporal changes in water quality as a result of age fluctuating hydraulic conditions were investigated drinking distribution system. Online measurements total intracellular adenosine tri-phosphate (ATP), intact cell concentrations measured with flow cytometry (FCM), turbidity, particle counts performed over five weeks at subsequent locations the The high number parallel ...

Biofilms comprise diverse bacteria and fungi with slime material, especially in humid conditions. The surface of the heat ventilation air conditioning (HVAC) system, at evaporator, is high moisture conditions due to compression relaxation refrigerant. electrically polarized molecules, which include polysaccharide, DNA, liposome, amino acids. Thus, when an electric field applied biofilms, create...

Abstract A defined Campylobacter coli ( C. ) suspension was inoculated on sterile sampling materials (cotton bud, polyester cellulose sponge) and pieces of lamb meat. Various combinations diluents (phosphate buffer saline ± Tween®80) methods (direct homogenization, simulating the excision method for meat, swabbing) were investigated recovery (detachment) cells from samples. The obtained bacteri...
