TOPIC: Imaging TYPE: Global Case Reports INTRODUCTION: A pulmonary contusion refers to an interstitial and/or alveolar lung injury without any frank laceration. It usually occurs secondary non-penetrating trauma. Pulmonary in 25–35% of all blunt chest traumas. we report a case with respiratory failure domestic fall from head down 5 meters. CASE PRESENTATION: 18 yrs old boy was admitted the hosp...

The human fungal pathogen Candida albicans resides asymptomatically in the gut of most healthy people but causes serious invasive diseases in immunocompromised patients. Many C. albicans strains have the ability to stochastically switch between distinct white and opaque cell types, but it is not known with certainty what role this switching plays in the physiology of the organism. Here, we repo...

Colony opacity phase variation in Acinetobacter baumannii strain AB5075 is regulated by a reversible high-frequency switch. Transposon mutagenesis was used to generate mutations that decreased the opaque to translucent switch and a gene encoding a predicted periplasmic membrane fusion component of a resistance-nodulation-cell division (RND)-type efflux system was isolated. This gene was designa...

In Candida albicans, the a1-alpha2 complex represses white-opaque switching, as well as mating. Based upon the assumption that the a1-alpha2 corepressor complex binds to the gene that regulates white-opaque switching, a chromatinimmunoprecipitation-microarray analysis strategy was used to identify 52 genes that bound to the complex. One of these genes, TOS9, exhibited an expression pattern cons...

Over the past few years, firms in the travel and entertainment industries have begun using novel sales strategies for revenue management. In this chapter, we study a selling strategy called opaque selling, in which firms guarantee one of several fully specified products, but hide the identity of the product that the consumer will actually obtain until after the purchase is completed. Several fi...

The zein proteins of eight opaque maize mutants were examined by reversed-phase high-performance liquid chromatography (RP-HPLC) and the microstructure of their endosperms by scanning electron microscopy (SEM). The opaque (0) mutants included 01, 05, 09) 010) 011) hI, Oh43JlI and V\ 64AJll. In these opaque mutant maize kernels, the proportion (%) of ex-zein, the major component of the alcohol-e...
