Infections in Hemopoietic Stem Cell Transplant Recipients, Part I
Abstract:
Hemopoietic stem cell transplantation, often called bone marrow transplantation, is a relatively new medical procedure that is now used to treat patients who were diagnosed with diseases once thought incurable, such as hematologic malignancies, immune deficiencies, solid tumors such as breast and ovarian cancers, sickle cell disease, and genetic-defect disorders. Patients who receive bone marrow transplantation also receive severe immunosuppression therapy as part of their care to minimize the risk of donor stem cell rejection. As a consequence of the patient's profound immunosuppression, opportunistic infections emerge as common causes of disease. Part I of this article will review some of the more common opportunistic fungal infections that can occur in these immunocomprom......

Responses of Staphylococcus aureus exposed to HCl and organic acid stress
Tone Mari Rode, Trond Møretrø, Solveig Langsrud, Ãyvind Langsrud, Gjermund Vogt, and Askild Holck - Staphylococcus aureus is an important food poisoning bacterium. In food preservation, acidification is a well-known method. Permeant weak organic acids, like lactic and acetic acids,... (Source: Canadian Journal of Microbiology)...

The in vivo efficacy of two administration routes of a phage cocktail to reduce numbers of Campylobacter coli and Campylobacter jejuni in chickens
Conclusions:
Our findings provide further evidence of the efficacy of phage therapy for the control of Campylobacter in poultry. The broad host range of the novel phage cocktail enabled it to target both C.jejuni and C.coli strains. Moreover the reduction of Campylobacter by approximately 2 log10cfu/g, as occurred in our study, could lead to a 30-fold reduction in the incidence of campylobacteriosis associated with consumption of chicken meals (according to mathematical models). To our knowledge this is the first report of phage being administered in feed to Campylobacter-infected chicks and our results show that it lead to an earlier and more sustainable reduction of Campylobacter than administration by oral gavage. Therefore the present study is of extreme importance as it has shown that......

Catalytic performance and thermostability of chloroperoxidase in reverse micelle: achievement of a catalytically favorable enzyme conformation.
Authors: Wang Y, Wu J, Ru X, Jiang Y, Hu M, Li S, Zhai Q
The catalytic performance of chloroperoxidase (CPO) in peroxidation of 2, 2'-azinobis-(-3 ethylbenzothiazoline-6-sulfononic acid) diammonium salt (ABTS) and oxidation of indole in a reverse micelle composed of surfactant-water-isooctane-pentanol was investigated and optimized in this work. Some positive results were obtained as follows: the peroxidation activity of CPO was enhanced 248% and 263%, while oxidation activity was enhanced 215% and 222% in cetyltrimethylammonium bromide (CTABr) reverse micelle medium and dodecyltrimethylammonium bromide (DTABr) medium, respectively. Thermostability was also greatly improved in reverse micelle: at 40 degrees C, CPO essentially lost all its activity after 5 h incubation, while 58-76% cat......

Hot-water pretreatment of cattails for extraction of cellulose.
Authors: Zhang B, Shahbazi A, Wang L, Diallo O, Whitmore A
To date in the US, production of renewable fuels, particularly ethanol, is primarily from food crops that are high in sugar and starch. The use of arable land for fuel rather than food production and the use of a food source for fuel rather than food have created issues in pricing and availability of traditional foods and feed. The use of cattails to produce biofuel will add value to land and also reduce emissions of greenhouse gases by replacing petroleum products. In order to investigate the feasibility of converting cattails into cellulosic ethanol, a hot-water pretreatment process was studied using a Dionex accelerated solvent extractor (ASE) varying treatment temperature and time. The pretreatment at 190 degrees C for more......

DTAF: an efficient probe to study cyanobacterial-plant interaction using confocal laser scanning microscopy (CLSM).
Authors: Ahmed M, Stal LJ, Hasnain S
A variety of microscopic techniques have been utilized to study cyanobacterial associations with plant roots, but confocal laser scanning microscopy (CLSM) is the least used due to the unavailability of a suitable fluorescent dye. Commonly used lectins have problems with their binding ability with root cells and their visualization under CLSM. DTAF (5-(4,6-dichlorotriazinyl) aminofluorescein) is a fluorescent dye that has been widely used for staining various biological samples for fluorescent microscopy. It reacts with polysaccharides and peptides at ordinary conditions. The possible application and efficiency of DTAF for CLSM studies were examined in various aspects of cyanobacterial-plant interactions. Seedlings of Pisum sativum, Vigna rediata an......

Modeling and optimization of lipase-catalyzed production of succinic acid ester using central composite design analysis.
Authors: Abdul Rahman MB, Jarmi NI, Chaibakhsh N, Basri M
Esterification of succinic acid with oleyl alcohol catalyzed by immobilized Candida antarctica lipase B (Novozym 435) was investigated in this study. Response surface methodology (RSM) based on a five-level, four-variable central composite design (CCD) was used to model and analyze the reaction. A total of 21 experiments representing different combinations of the four parameters including temperature (35-65 degrees C), time (30-450 min), enzyme amount (20-400 mg), and alcohol:acid molar ratio (1:1-8:1) were generated. A partial cubic equation could accurately model the response surface with a R(2) of 0.9853. The effect and interactions of the variables on the ester synthesis were also studied. Temperature was found to be the mos......
