Background and Aims: Given the importance of aminoglycoside resistance in nosocomial and community infections caused by bacterial pathogenes such as Klebsiella pneumoniae (K. pneumoniae), the aim of this study was to determine the frequency of aac (6')- Ib and aac (3)- IIa, the genes encoding aminoglycoside modifying enzymes involved in aminoglycoside resistance. Material and Methods: A t...

A 68-year-old man, following mitral valve replacement, presented with a low-grade chronic consumptive coagulopathy. Laboratory analysis showed mild fibrinolysis, minimal effect of coumadin therapy, and a prolonged thrombin time (greater than 150 seconds using bovine IIa). When purified human IIa was used the thrombin time normalized to within 17 seconds of controls, suggesting a possible inhibi...

Principle Investigators: Hilbert v. Löhneysen, Christoph Sürgers, Detlef Beckmann CFN-Financed Scientists: Alexander Cosceev (BAT IIa, 6 months), Michael Marz (71% BAT IIa, 36 months), Heiko Stalzer (BAT IIa, 6 months), Niraj Joshi (BAT IIa, 12 months), Marc Müller (5/8 BAT IIa, 6 months), Oliver Berg (1/2 BAT IIa, 5,5 months), Sebastian Zaum (3/4 BAT IIa, 3 months) Further Scientists: Florian ...

The interaction of human thrombospondin (TSP) with GPIa-IIa and GPIIb-IIIa was studied. The binding for both proteins became time-independent after 60 min. A 7-fold excess concentration of unlabelled GPIa-IIa added either initially, or after time-dependent binding, resulted in a 50% inhibition of GPIa-IIa bound to TSP. GPIa-IIa and GPIIb-IIIa specifically bound TSP since: (a) the binding of GPI...

Phakomatosis Pigmentovascularis (PPV) is a rare cutaneous congenital malformation syndrome, defined as simultaneous occurrence of congenital cutaneous vascular and pigmentary anomalies. As most of the reported cases are from Far East countries, especially Japan, we reported a case of PPV type IIa in an Iranian patient. This case was unusual because of the coexistence of unilateral extensive por...

The structure and function LT-IIa, a type II heat-labile enterotoxin of Escherichia coli, are closely related to the structures and functions of cholera toxin and LT-I, the type I heat-labile enterotoxins of Vibrio cholerae and enterotoxigenic Escherichia coli, respectively. While LT-IIa is a potent systemic and mucosal adjuvant, recent studies demonstrated that mutant LT-IIa(T34I), which exhib...

Human serum albumin (HSA) is the most abundant protein in the blood plasma. Molecular dynamics simulations of subdomain IIA of HSA and its complex with salicylic acid (SAL) were performed to investigate structural changes induced by the ligand binding. To estimate the binding affinity of SAL molecule to subdomains IB and IIA in HSA protein, binding free energies were calculated using the Molecu...

cutis laxa is an acquired or inherited condition characterized by redundant, sagging and inelastic skin.  the inherited form is heterogeneous condition with autosomal dominant, autosomal recessive and x-linked inheritance.  autosomal dominant cutis laxa is divided into three types, type i, ii and iii and the responsible genes are eln, fbln5 and aldh18a1 respectively. an x-linked form of cutis l...

isolated bilateral internal iliac artery (iia) aneurysm is a rare and potentially lethal disease. endovascular repair of this disorder is a matter of debate. a symptomatic 68-year-old male presented with severe pelvic pains. computed tomography revealed a leaking 46-mm aneurysm in the right iia, a 27-mm aneurysm in the left iia, and ectatic changes at a diameter of 31 mm in the right common ili...

OBJECTIVE Group IIa secretory phospholipase A2 (sPLA2 IIa) plays a role in the malignant potential of several epithelial cancers. It is overexpressed in many cancer specimens and its elevated levels are correlated with high tumor grade and metastasis. Here, we evaluate the clinical significance of sPLA2 IIa in lung adenocarcinoma and the role of sPLA2 IIa in the process of cancer cell invasion ...
