The reaction of NO with manganoglobin, manganous porphyrin-substituted hemoglobin (MnHb), shows close correspondence to the reaction of CO with hemoglobin (Hb) in all features examined. All measurements are consistent with cooperative binding of NO by MnHb, associated with a T + R conformation change in the tetramer. An important conclusion based on a comparison of rates of NO ligation by Hb an...

To the Editor: Stenotrophomonas maltophilia has emerged as an important nosocomial pathogen, especially in debilitated and immunocompro-mised persons (1). However, comparatively little is known of the epidemiology of this bacterium, and sources and routes of transmission of S. mal-tophilia are not well understood. The bacterium is widely distributed in the environment, including in plant rhi-zo...

Brilliant blue is largely found in ice cream, canned processed peas, packet soups, blue raspberry flavored products, dairy products, sweets and drinks. It is also used in soaps, shampoos, mouthwash and other hygiene and cosmetics applications (Archived from Florida). This study was aimed to investigate the antimicrobial effects of Brilliant blue on Bacillus subtilis as a gram positive bacterial...

vulvar cancer is a rare gynecological malignancy with mainly lymphatic spread. sentinel node mapping plays an important role in the management of this gynecological malignancy. in the current study, we reported our experience in sentinel node mapping of vulvar cancer and review the literature accordingly. since the introduction of sentinel node mapping to the surgical oncology community of our ...

in the present investigation, shells of pistachio are used as adsorbents and they have been successfully used for the removal of blue 56, from water samples. the effect of various parameters such as: ph, amounts of adsorbents, size of adsorbent particles and contact time on removal processing were investigated. in this study freundlich absorption isotherms and langmuir were investigated . the e...

background and objectives: activated carbon is an adsorbent which is mostly employed in order to remove dye from aqueous solutions; however, commercial activated carbon is expensive and this is considered as an obstacle for its usage. therefore, the present study aimed to use waste paper as an inexpensive precursor to produce activated carbon. materials and methods: in the present study, koh wa...

introduction: skeletal staining is an important part of anatomical studies which can evaluate macroscopic disorders in bones and cartilages development. the aim of the present article is to illustrate two distinct protocols by all details in order to stain skeletal system of the lab animals in all ages of their lives so it becomes easy for future studies in this field. methods: in this paper, s...
