The β-barrel assembly machinery (BAM) is a ∼203 kDa complex of five proteins (BamA-E), which is essential for viability in E. coli. BAM promotes the folding and insertion of β-barrel proteins into the outer membrane via a poorly understood mechanism. Several current models suggest that BAM functions through a 'lateral gating' motion of the β-barrel of BamA. Here we present a cryo-EM structure o...

The BAM HI family of long interspersed DNAs in mice represent as much as 0.5% of the mouse genome. Cloned mouse DNA fragments which contain BAM HI/non-BAM HI junction sequences have been analyzed by restriction mapping and DNA sequencing. It has been found that BAM HI elements: (i) are approximately 7 kilobase pairs in size, (ii) are not bracketed by long repeated sequences analogous to the ter...

The La0.67Sr0.33MnO3 /BaFe11.3~ZnSn!0.7O19 ~LSMO/BaM! composites have been prepared by cosintering the LSMO and the BaM powders. The microstructural, magnetic, and magnetoresistive ~MR! properties of those systems were systematically studied. Due to the magnetic coupling between the LSMO ~a soft magnet metal! and BaM ~a hard magnet insulator! grains, the low-field MR sensitivity was reduced and...

results in this study, high resistances were found to nalidixic acid (59.7%) and gentamicin (52.3%) but high susceptibilities were found to ciprofloxacin (59.3%) and ceftriaxone (36.3%). conclusions according to the results obtained in this study ciprofloxacin is an effective antibiotic in e. coli infections. objectives the current study aimed to investigate the resistance of escherichia coli a...

dubas bug, ommatissus lybicus de bergevin (hem.: tropiduchidae), is a key pest of date palms in iran.this pest was first reported on date palms in 1966 and has been established throughout the date producing regions in southern iran since. date palm is the only host plant of dubas bug. it attacks almost all date palm varieties, esp. mazafati variety in city of bam, kerman province and other vari...

BACKGROUND With the increasing number of elderly, especially in recent decades, transfer to nursing homes and the number of centers has also increased but experiences and problems of elders in these centers is less considered. So, the goal of this study is to explore the Elderly peoples' experiences of nursing homes. METHODS The current research was performed using a phenomenological approach...
