In this study, we reviewed and summarized the data on permafrost groundwater areas of Central Yakutia to understand formation distribution subpermafrost mineral waters sodium bicarbonate chloride-bicarbonate types, evaluate their potential use for medical purposes. Analysis indicated that these low-mineralized groundwaters are basic analogues Maykop Karachi waters, with no particular bioactive ...

In the present study, biochars from rice husk were synthesized via pyrolysis at 400, 550, 700 and 850 °C for 1 h under a limited O2 atmosphere, characterized with various techniques of used as catalysts to activate persulfate degrade sulfamethoxazole (SMX). After physicochemical characterization biochars. SMX degradation tests performed using different water matrices, biochar concentrations ini...

In a water-scarce country such as Pakistan, rainfall is the third-largest source of freshwater. most urban cities country, rainwater mixed with sewerage and rendered useless for managed aquifer recharge purposes. Therefore, this study investigates potential in Lahore (Pakistan). The present research was designed conducted by Irrigation Research Institute (IRI). Three different sites were select...

We studied equilibrium adsorption and uptake kinetics and identified molecular species that formed during sorption of carbon dioxide on amine-modified silica. Bicontinuous silicas (AMS-6 and MCM-48) were postsynthetically modified with (3-aminopropyl)triethoxysilane or (3-aminopropyl)methyldiethoxysilane, and amine-modified AMS-6 adsorbed more CO(2) than did amine-modified MCM-48. By in situ FT...

To understand the Hydro-Geochemistry of urban and semi urban areas of Karachi, located in an arid region of Pakistan, various physico-chemical parameters were investigated. Only continuously pumped productive deep and shallow wells and tube wells were chosen for the analysis for their best ecological functions including drinking, domestic, industrial and agricultural activities. Multivariate st...

Water Pollution is an alarm at the global level. The groundwater is continuously decreasing, in anthropogenic pressure as well as naturally. Arsenic is one of the prominent contaminant, which is degrading the quality of groundwater naturally. In India, arsenic pollution in groundwater is mainly reported from West Bengal. Since its first reported case in early eighties, there are 1312 affected v...

Citrate synthase (CS) is involved in citric acid biosynthesis which is a well-established metabolic pathway. The condensation of acetyl-CoA with oxaloacetate is catalyzed by CS. Citric acid (CA) has a number of applications in pharmaceutical industry. CA in combination with bicarbonates is used as an effervescent in the preparations of tablets and powders. It has also been used as an anticoagul...

The aim of this work was to obtain a black coffee brew to be consumed hot by extension of its shelf life, by addition of additives. Four pH-regulator agents (sodium and potassium carbonates and bicarbonates), one pH regulator and antioxidant (sodium citrate), three antioxidants [sodium ascorbate, ethylenediaminetetracetic acid (EDTA), and sodium sulfite], and lactoserum were tested by sensory a...

The effects of mucosally added Escherichia coli heat stable enterotoxin (STa 30 ng ml(-1)) on the basal short-circuit current (Isc in microA cm(-2)) across stripped and unstripped sheets of jejuna and ilea taken from fed, starved (4 days, water ad lib) and undernourished (50% control food intake for 21 days) gerbil (Gerbillus cheesmani) were investigated. The effect of neurotoxin tetrodotoxin (...

Infectious mononucleosis (IM) by Epstein-Barr virus is usually a benign, self-limiting disease. Mild to moderate immune thrombocytopenia in the setting of IM is very common and appears in approximately half of these patients, however it rarely presents in severe form and troublesome haemorrhage is even rarer. Rapid spontaneous resolution is possible, with the role of steroids being controversia...
