Potential health effects of drinking water quality changes caused by acid precipitation are presented. Several different types of water supply are discussed and their roles in modifying acid rain impacts on drinking water are explained. Sources of metals contamination in surface water supplies are enumerated. The authors present some results from their research into acid rain impacts on roof-ca...

BACKGROUND AND PURPOSE Anosmia frequently occurs after aneurysmal subarachnoid hemorrhage not only after clipping, but also after endovascular coiling. Thus, at least in part, anosmia is caused by the hemorrhage itself and not only by surgical treatment. However, it is unknown whether anosmia is related to rupture of the aneurysm with sudden increase in intracranial pressure or to the presence ...

In the present study, the feasibility of intrathecal indwelling catheters in the preparation of a repeated subarachnoid hemorrhage (SAH) model in dogs, as well as chronic intrathecal administration of therapeutic agents against the ensuing cerebral vasospasm was examined. Briefly, through a small suboccipital incision, two catheters were introduced into the subarachnoid space so that their tips...

This paper studies how in utero exposure to a large-scale climate adaptation program affects birth outcomes. The built around one million cisterns Brazil's poorest and driest region promote small-scale decentralized rainfall harvesting. Access during early pregnancy increased weight, particularly for more educated women. Data suggest that women complied with the program's water disinfection tra...

Background: In 15% to 20%o of patients with a spontaneous subarachnoid hemorrhage, no aneurysm is found on the first angiogram. This review emphasizes that this group of patients is in fact heterogeneous and describes the clinical features, pattern of hemorrhage on early computed tomographic (CT) scan, prognosis, and proposed management in the several and distinct subsets of these patients. Sum...

Synaptic activity-dependent changes in the spatio-temporal distribution of calcium ions regulate important neuronal functions such as dendritic integration and synaptic plasticity, but the processes that terminate the free Ca2+ transients associated with these changes remain unclear. We have characterized at the electron microscopic level the intracellular compartments involved in buffering fre...

Meningeal melanocytoma is a primary melanocytic neoplasm with certain MR and immunohistochemical characteristics worthy to note. In a 38-year-old man with a complaint of headache for a couple of years and recently added nausea, vomiting, diplopia, progressive visual blurring and hearing loss, magnetic resonance imaging (MRI) was remarkable for T1 shortening of leptomeninges and certain nodules ...

The demand fish feeder, which was made-up of Fibre Reinforced Plastic (FRP) material was designed with an angle of repose 50 and tested in outdoor conditions. It was fabricated with general-purpose tools at a cost of Rs. 3,100 (US $ 69) in 2007. It was maintenance free and easy to operate. It was tested in cisterns of 10m capacity at the CIFA farm, Bhubaneswar for a period of 110 days to evalua...

BACKGROUND AND PURPOSE The feasibility of preventing vasospasm by intrathecal anterograde infusion of urokinase (UK) into the cisterna magna was studied in patients with recently ruptured aneurysms who had just undergone the placement of a Guglielmi detachable coil (GDC). METHODS Immediately after complete embolization with the use of GDC-10 coils, 15 patients with Hunt and Hess neurological ...
