PURPOSE To investigate whether any of the fluorophores in the human lens nuclei might be responsible for human brunescent cataract formation. METHODS Human lens nuclei (non-brunescent, from 13; brunescent, from 8) were obtained after extracapsular cataract extraction in nondiabetic patients. Protein-free extract, prepared by filtrating the water-soluble fraction of each nucleus through a cent...

The circadian locomotor rhythm of the terrestrial slug, Limax maximus, was measured with activity wheels during exposure to both humid and drying conditions. Slugs kept in wet wheels (100% RH) remained fully hydrated while those in dry wheels (less than 30% RH) experienced progressive dehydration. Transfer of slugs from a wet wheel to a dry wheel resulted in an increase in the intensity and dur...

The knowledge of the area of interfaces between phases is important to understand and quantify many flow and transport processes in porous media. In this work, we apply the interfacial tracer technique to study the dependence of fluid-fluid interfacial area on saturation and wettability. The interfacial area between the wetting and the nonwetting phases (brine and decane) in unconsolidated poro...

Objectives. Reduction in serum lipoproteins, especially LDL cholesterol, is a preventive approach against atherosclerosis. Bloodletting has been a recommended method to reduce serum lipoprotein concentrations. Present study was conducted to investigate the effects of wet cupping as a method of bloodletting on serum lipoproteins. In a randomized controlled trial, 47 men, 18-25 years old, without...

OBJECTIVE The objectives of this study were to 1) determine the prevalance and characterize the symptomatology of Trichomonas vaginalis (TV) infection in pregnant women on entry into prenatal care in an inner-city population; 2) compare conventional microscopic methods vs. culture techniques in diagnosing TV in both symptomatic and asymptomatic pregnant patients; and 3) correlate wet mount micr...

Although wet cupping is quite a popular procedure that is practised worldwide, there is not enough evidence that it may cause anaemia as a side effect. In this observational retrospective pre–post study, we looked through the previously recorded data of patients who received wet cupping at King Abdulaziz University Hospital. We included in the study all those who had their complete blood count ...

Particle size may significantly affect the speed and stability of anaerobic digestion, and matching the choice of particle size reduction equipment to digester type can thus determine the success or failure of the process. In the current research the organic fraction of municipal solid waste was processed using a combination of a shear shredder, rotary cutter and wet macerator to produce stream...

Wet work is the main cause of occupational contact dermatitis in the cleaning industry. Dermatologists and occupational physicians need to base their primary and secondary prevention for workers in the cleaning industry on the characteristics of wet work exposures. We quantified the burden of wet work in professional office cleaning activities with a continuous standardized observation by train...
