Pure, Nd doped and Nd:Yb co-doped barium chloride dihydrate (BaCl2·2H2O) single crystals were grown and analyzed with various characterization techniques. The measured unit cell parameters show that the grown crystals belong to monoclinic system. Powder X-ray diffraction spectra indicates that ...

Uranyl bromate monohydrate UO2(BrO3)2 · H2O was obtained as a greenish-yellow solid by the metathesis of a uranyl sulfate solution with a stoichiometric amount of barium bromate solution. On evaporation of the supernatant of the precipitated BaSO4 a greenish-yellow syrup was obtained which, on ...

Arsenite directly binds to the zinc finger domains of the DNA repair protein poly (ADP ribose) polymerase (PARP)-1, and inhibits PARP-1 activity in the base excision repair (BER) pathway. PARP inhibition by arsenite enhances ultraviolet radiation (UVR)-induced DNA damage in keratinocytes, and th...

BackgroundHaloferax mediterranei is a denitrifying haloarchaeon using nitrate as a respiratory electron acceptor under anaerobic conditions in a reaction catalysed by pNarGH. Other ions such as bromate, perchlorate and chlorate can also be reduced.

The preparation of cadmium nitrate complex with bridged hexamethylenetetramine-[{Cd(HMTA)(NO3)2(H2O)2}n], CHNC, of polymeric nature has been reported here for the first time. It was characterized by X-ray crystallography, 1H NMR, FT-IR and elemental analysis. The crystal structure is stabilized ...

In order to grow and effectively uptake and accumulate cadmium (Cd), plants used for phytoextraction have to cope with toxicity, which may be influenced by the supply of nitrate (NO3−) and ammonium (NH4+). Thus, we evaluated the effect of these nitrogen forms on the photosynthetic and antioxidan...

Plants benefit from the simultaneous uptake of nitrate (NO3−) and ammonium (NH4+), which can influence the bioaccumulation of heavy metals. Nevertheless, there are no studies on the effect of nitrogen forms on grasses used for cadmium (Cd) phytoextraction. The objective was to evaluate the respo...

Vapour pressures of water over saturated solutions of cadmium salts (chloride, bromide, iodide, nitrate, and sulphate) were determined over the temperature range 280 K to 322 K and compared with the literature data. The vapour pressures determined were used to obtain the water activities, osmoti...

The nitrate complexes of group 12 elements with a tridentate Schiff base ligand (L = (E)-N1-((E)-3- phenylallylidene)-N2-(2-((E)-((E)-3-phenylallylidene) amino)ethyl) ethane-1,2-diamine) were synthesized via sonochemical process and characterized by various physical and chemical methods. The str...

Elevated cadmium (Cd) concentrations in groundwater have widespread implications for water supply and agriculture. The aqueous chemistry of Cd is considered not complex; however, aside from intense industrial pollution, multi-faceted hydrogeochemical interactions control Cd mobility. Therefore, ...

The hepatic metabolism of 3-oxoandrost-4-ene-17β-carboxylic acid (etienic acid), a probable acidic catabolite of deoxycorticosterone, was investigated using rats prepared with an external biliary fistula. Metabolic products were identified by GC-MS after hydrolysis with β-glucuronidase and by ...

Following the i.v. injection of 10 mg 7α-[su3]H]-EME in a normal female subject, plasma and urinary samples were assayed for free and conjugated C20-steroids. Five min after administration of the substrate, the fraction of free acidic C20-steroids in plasma contained more [3H]-activity than the...

Bovine adrenocortical mitochondria were sonicated and subjected to extraction with sodium cholate. The extract contained not only cytochrome P-450 activities, but also an activity which catalyzed the conversion of deoxycorticosterone to an unknown steroid (designated X). The latter activity was ...

Linear oligoesters based on etienic acid (3β-hydroxyandrost-5-ene-17β-carboxylic acid) containing four steroid units were prepared using a 2 + 2 synthetic strategy in a successful synthesis of 3β-{[3β-({3β-[(3β-hydroxyandrost-5-ene-17β-carbonyl)oxy]androst-5-ene-17β-carbonyl}oxy)androst-...

β-D-xylosides with cytotoxic aglycones have augmented cytotoxicity towards animal cells because β-D-xyloside-primed glycosaminoglycans further enhance the aglycone's cytotoxicity. In this study, we designed and synthesized different 4-anilinequinazoline β-D-xylosides and found that compo...

As d-amino acids play important roles in the physiological metabolism of bacteria, combination of d-amino acids with antibiotics may provide synergistic antibacterial activity. The aim of the study was to evaluate in vitro and in vivo activity of d-serine alone and in combination with β-lactams...

Alkyl glycosides as modern industrial manufactured products are important. Furthermore, the better water solubility should make them a greater potential application value. In this study, an improvement of water solubility has been realized by adding the oxyethene fragment (−OCH2CH2) as a hydroph...

In this study, the (1→3)-β-D-glucan was isolated from yeast cell wall for investigating its effect on reducing the postharvest decay of pear fruit caused by Penicillium expansum and the underlying mechanisms. The results demonstrated that (1→3)-β-D-glucan could significantly induce disease r...

Alzheimer’s disease (AD) is a multifaceted neurodegenerative disorder affecting the elderly people. For the AD treatment, there is inefficiency in the existing medication, as these drugs reduce only the symptoms of the disease. Since multiple pathological proteins are involved in the developmen...

The effects of cholesteryl phosphate and cholesteryl sulfate on the LaHII phase transition temperature of dielaidoylphosphatidylethanolamine were compared. Both compounds raise the LaHII transition temperature. This effect is decreased with decreasing pH. Cholesteryl sulfate is a somewhat be...
