CO2 Storage in Saline Aquifers — Saline aquifers represent a promising way for CO2 sequestration. Storage capacities of saline aquifers are very important around the world. The Sleipner site in the North Sea is currently the single case world-wide of CO2 storage in a saline aquifer. A general review is given on the specific risks for CO2 storage in saline aquifer. The regional distribution of C...

Amorphophallus paeoniifolius known as Elephant foot yam is a highly potential tropical tuber crop of Areace family. The tubers are rich in nutrients. It is a healthy low-fat food containing a good source of protein as well as starch. It is a natural product that is high in fiber, rich in potassium, calcium (50 mg g-1), phosphorus (34 mg g-1) vitamin A (260 IU g-1), vitamin B6, as well as with t...

All environments inhabited by humans contain microbes. The detection and elimination of harmful fungi and bacteria in closed system environments such as spacecraft is of vital importance. Biological waste products of microbes can cause “sick building syndrome,” structural damage, and pose a fire hazard. Traditional means of detecting and quantifying these microbes, GC/MS and HPLC, are too bulky...

The ability of transient receptor potential (TRP) channels to sense and respond to environmental and endogenous cues is crucial in animal sensory physiology. The molecular mechanism of channel gating is yet elusive. The TRP box, a conserved region in the N-end of the C-terminus domain, has been signaled as pivotal for allosteric activation in TRP channels. Here, we have examined the role of the...

The physical absorption has been experimentally investigated in a bubble column for to determination of volumetric mass transfer coefficients referred to the liquid phase, kLa, and quantify the effect of the viscosity of the absorbent solution on the same, operating in continuous and batch regime with respect to the liquid phase. The variables studied in the process have been the physical prope...

DNA double-strand breaks (DSBs), caused by either exogenous or endogenous factors, will lead to cell death unless repaired by DNA repair pathways that maintain genome stability. DNA polymerase 4 (Pol4) has been implicated in a pathway of DSB repair called microhomology-mediated endjoining (MMEJ), which uses short segments of microhomologies (5-25 bps) to repair DSBs. To determine the role of Po...

The poly(A)-binding protein (PABP) is able to interact with the 3’ poly(A) tail of eukaryotic mRNA, promoting its translation. Cleavage of PABP by viral proteases encoded by several picornaviruses and caliciviruses plays a part in the abrogation of cellular protein synthesis. We report that infection of MT-2 cells with HIV-1 leads to an efficient proteolysis of PABP. Analysis of PABP integrity ...

Introduction: Toxocariasis is a helminthiasis caused by Toxocara ssp., and result of the migration of infective larvae into the visceral, causing disease. There are 21 species belonging to the Toxocara genus, but only T. canis and T. cati are important in public health. Objetctive: To produce a review of the literature about human toxocariasis using the methodology of secondary data analysis. T...
