Hypoxic pulmonary vasoconstriction (HPV) matches lung perfusion with ventilation. Controversy exists whether decreased or increased reactive oxygen species may elicit HPV and from which source such oxygen metabolites are derived. In rabbit lungs, we detected transcripts of a nonphagocytic NADPH oxidase subunit homologous to mitogenic oxidase-1 (Mox1) or NADPH oxidase homolog 1 (NOH-1L). In perf...

We have utilized processing-defective derivatives of the outer membrane maltoporin, LamB, to study protein trafficking functions in the cell envelope of Escherichia coli. Our model proteins contain amino acid substitutions in the consensus site for cleavage by signal peptidase. As a result, the signal sequence is cleaved with reduced efficiency, effectively tethering the precursor protein to th...

Pasaulyje sparčiai didėjantis sergamumas psichiatriniais sutrikimais, o ypač – vaistams atsparia depresija, pasta­raisiais metais paskatino susidomėjimą neuromodulia­ciniais gydymo metodais, sudarydamas sąlygas naujų mokslinių tyrinėjimų atsiradimui. Tyrimo tikslas − api­bendrinti naujausias mokslines publikacijas, apžvelgian­čias neuromoduliacinių metodų transkranijinės magne­tinės stimuliacij...

BACKGROUND: Avian Colibacillosis can lead to important economic losses in the poultry industry. Escherichia coli the causative agent of this disease has acquired resistance to different antibiotics, including tetracycline. OBJECTIVES: This study was carried out to detect the distribution of tetracycline Group І efflux genes genes among E.coli isolates from from avian colibacillosis in Iran by P...

The technological aspects of modification epoxy oligomer DER – 331 to provide improvement thermophysical characteristics composite materials and protective coatings based on them are presented. Cold-cured triethylenetetramine TETA hardener was used crosslink the binder (q = 10 parts by weight per 100 DER-331 resin). Thermogravimetric (TGA) differential thermal (DTA) analysis performed study mod...

Bu çalışmada, sağlıklı ve nöbet esnasındaki EEG sinyallerini ayrıştıran bir sistem tasarımı amaçlanmıştır. Bunun için İlinti Boyutu, Dalgacık-entropisi ve Destek Vektör Makinesi(DVM) içeren kompozit bir sistem önerilmiştir. Çalışmada kullanılan EEG verileri, Bonn Üniversitesi Epileptoloji bölümü veritabanından alınmıştır. Bu veritabanından 50 adet sağlıklı ve 50 adet epileptik olmak üzere topla...
