The addition of 1 micromolar 2,3,5-triiodobenzoic acid (TIBA) to solutions containing KCl resulted in the inhibition of K and Cl uptake in excised barley roots. The effectiveness of TIBA as an inhibitor increased as the pH of the treatment solution decreased and approached the pK(a) of TIBA. A lag period of approximately 20 minutes existed prior to the onset of TIBA induced inhibition of ion up...

Diagnosis of lung hydatidosis becomes difficult with unusual radiographic findings especially with rupture of hydatid cyst. Here we present the case of a patient who presented with hydatid cyst with endobronchial rupture. A 40-year-old woman presented with a 3-year history of cough with mucoid expectoration, breathlessness on exertion, intermittent fever and left-sided chest pain. Chest radiogr...

In present study, the potential drug delivery of nanoformulations was validated via the comparison of cellular uptake of nanoparticles in various cell lines and in vivo pulmonary cellular uptake in intratracheally (IT) dosed rat model. Nanoparticles were prepared by a bench scale wet milling device and incubated with a series of cell lines, including Caco-2, RAW, MDCK and MDCK transfected MDR1 ...

While Malaysia produces about half of the world’s palm oil and is largest producer exporter worldwide, industries generate large amounts lignocellulosic biomass waste as a sub-product with no economic market value other than feedstock for energy valorisation. With aim to increase sustainability sector, in this work we prepare new materials CO2 capture from residues (empty fruit bunches kernels)...

Intracellular delivery of material is a long-standing challenge for both therapeutic and research applications. Existing technologies rely on a variety of mechanisms to facilitate delivery. Vector-based methods, such as polymeric nanoparticles and liposomes, form complexes with the target material and subsequently facilitate its uptake by the cell of interest, often through endocytosis. Althoug...

fifteen kinds of local wetland plants in taihu lake region of china were investigated on their respective growth conditions, biomass allocations and nutrient uptake capacities. the test plants were cultured in 3 l nutrient solutions for 28 days with nh4 +-n, no3 --n and p concentrations of 38.5, 132.8 and 10 mg/l, respectively. mean species total biomass ranged from 1.2-21.6 g/plant with a...

in this study the uptake and metabolism of adenosine by mitochondria has been investigated. incubation of cem cells mitochondria preparation with [3h] -adenosine showed substantial uptake and metabolism of adenosine. adenosine was both anabolized to amp, adp and atp, and also catabolized to inosine. the highest concentration of metabolites in extracted mitochondria was due to amp. the mitochond...

the synthesis of nano- structured cobalt through a controlled chemical process followed by heat treating at various temperatures is studied. the product is characterized by icp, xrd, fesem , and tem, indicating that the as- synthesized particles have an amorphous structure with 1.76 for co/b ratio, an average size of 50 nm. the transformation of intermediate phases into single phase nano- cryst...
