The effect of the solvent butanol on the complexation reaction of allylacetoacetate (AAA) with titanium tetraethoxide. (Ti(OEt)4) in molar ratio Ti(OEt)4:AAA = 1:1 was investigated by C-NMR, FT-IR spectroscopy and elemental analysis. The investigation shows that some ethoxy groups that are attached to the titanium are substituted with butoxy groups. The hydrolytic stability of the allylacetoace...

BACKGROUND Staphylococcus aureus is a frequent cause of serious and life-threatening infections, such as endocarditis, osteomyelitis, pneumonia, and sepsis. Its adherence to various host structures is crucial for the establishment of diseases. Adherence may be mediated by a variety of adhesins, among them the autolysin/adhesins Atl and Aaa. Aaa is composed of three N-terminal repeated sequences...

background:abdominal aortic aneurysm (aaa) is widely considered as the disease of elderly white men. inflammation is one of the most well-known mechanisms involved in the pathogenesis of aaa. magnesium is one of the most important minerals in the body with established anti-inflammatory effects. in this study, we aimed to investigate the impact of mg loading following aaa surgery on two inflamma...

BACKGROUND Recent genome-wide studies have shown a significant association of a locus on chromosome 9p21.3 and coronary artery disease. We performed a case-control study to investigate the association between this locus and abdominal aortic aneurysm (AAA). METHODS AND RESULTS A total of 1714 patients (899 patients with AAA and 815 controls) were genotyped for the lead single-nucleotide polymo...

PURPOSE To determine the predictive value of serum lipid levels on the development of later cardiovascular events after abdominal aortic aneurysm (AAA) surgery. METHODS A total of 101 patients under 70 undergoing an elective AAA surgery were divided into the following two groups: 1) those who developed later cardiovascular events after AAA surgery, including cerebral infarction (n = 4), cathe...

The healing process of resected, autoclaved (121 degrees C, 20 minutes) and re-implanted bone in the rat parietal bone was compared with that of autoclaved bone that was supplemented with allogenic bone matrix (AAA-bone), using a scanning electron microscope and a light microscope. In the implant without AAA-bone, bone union and replacement of the autoclaved bone was seen at 2 weeks after impla...

sometimes unexpected results which have emerged, and looks to future developments. This paper describes the simulation of electric storage heaters and their controls. A method for modelling manual control, inferred from transformer readings, is described. Use of the dynamic simulation language ESL compiled into a single program with an existing building simulation program, is explained. This pr...

Rvb1 and Rvb2 are highly conserved and essential eukaryotic AAA+ proteins linked to a wide range of cellular processes. AAA+ proteins are ATPases associated with diverse cellular activities and are characterized by the presence of one or more AAA+ domains. These domains have the canonical Walker A and Walker B nucleotide binding and hydrolysis motifs. Rvb1 and Rvb2 have been found to be part of...

BACKGROUND Abdominal aortic aneurysm (AAA) has a multifactorial etiology and the relevance of genetic factors is getting increasing interest, in particular those related to the destructive remodeling of extracellular matrix. METHODS We performed a candidate gene association study of polymorphisms in genes coding matrix metalloproteinases (MMPs), tissue inhibitors of MMPs (TIMPs), and elastin ...

The D.C. electroretinogram of four adult albino rabbits was studied 13.5 to 15 hr after injection of 0.1 ml of 0.15M DL-alpha-aminoadipic acid (alpha-AAA) into the vitreous body of one eye. The other eye was similarly injected with saline and served as control. In the alpha-AAA--treated eye the b-wave was markedly reduced or absent and the a- and c-waves increased compared with the control eye....
