OBJECTIVES To find out the frequency of Alzheimer's and Vascular dementia in the elderly patients. METHODS This cross sectional descriptive study was conducted in Department of Medicine, Ziauddin Hospital Karachi from 1st October 2013 to 31st March 2014. Patients with symptoms of dementia for more than 6 months duration, and Mini Mental State Examination score <24 were included in this study....

A model developed to simulate the behavior of oil and gas accidentally released from deep water is presented. This model presents major modifications to a three-dimensional model developed earlier (Yapa and Zheng, 1997) that simulate the behaviour of oil from under water accidents (shallow water). In deepwater, the ultra-high pressure and cold temperature causes phase changes in gases. These co...

BACKGROUND Fluoride is an essential element for human health. However, excess fluoride in drinking water may cause dental and/or skeletal fluorosis. Drinking water is the main route of fluoride intake. The aim of the present study was to measure fluoride levels in human breast milk collected from two regions of Golestan Province, northern Iran with different amount of fluoride concentration of ...

Music and speech are very cognitively demanding auditory phenomena generally attributed to cortical rather than subcortical circuitry. We examined brainstem encoding of linguistic pitch and found that musicians show more robust and faithful encoding compared with nonmusicians. These results not only implicate a common subcortical manifestation for two presumed cortical functions, but also a pos...

The challenge of devising a set of biomarkers capable of measuring the ageing rate in human subjects was articulated long ago. In recent years, progress in the basic biology of ageing suggests the realistic possibility of preventive or restaurative interventions that may extend healthy lifespan in mammals including human subjects. Specifically, frailty is being increasingly recognised as a clin...

G protein–coupled receptors (GPCRs) regulate a wide variety of physiological functions in response to structurally diverse ligands ranging from cations and small organic molecules to peptides and glycoproteins. For many GPCRs, structurally related ligands can have diverse efficacy profiles. To investigate the process of ligand binding and activation, we used fluorescence spectroscopy to study t...

The JAPEX/JNOC/GSC et al. Mallik 5L-38 gas hydrate research well was drilled to 1166 m through about 200 m of subpermafrost gas-hydrate-bearing sediments under the Mackenzie Delta, Canada. An extensive logging program was completed to characterize in situ the physical properties of the sediments where gas hydrate fills as much as 80% of the pore space. Analysis of sonic logging waveform show th...
