Background Successful engraftment and reconstitution of the innate and adaptive immune system are associated with improved outcomes in recipients of allogeneic hematopoietic stem cell transplantation (HSCT). A clinically meaningful and simple biomarker of immunosuppression could potentially assist clinicians in their decision-making. We aimed to determine the relationship between T-cell product...
Reduced downstream costs, together with high purity recovery of polyhydroxyalkanoate (PHA), will accelerate the commercialization of high quality PHA-based products. In this work, a process was designed for effective recovery of the copolymer poly(hydroxybutyrate-co-hydroxyhexanoate) (P(HB-co-HHx)) containing high levels of HHx (>15 mol%) from Ralstonia eutropha biomass using non-halogenated so...
A practical antibiotics-free plasmid expression system in cyanobacteria was developed by using the complementation of cyanobacterial recA null mutation with the EscherichiacolirecA gene on the plasmid. This system was applied to the production of polyhydroxyalkanoate (PHA), a biodegradable plastic, and the transgenic cyanobacteria stably maintained the pha genes for PHA production in the antibi...
Animals utilize specialized sensory neurons enabling the detection of a wide range of environmental stimuli from the presence of toxic chemicals to that of touch. However, how these neurons discriminate between different kinds of stimuli remains poorly understood. By combining in vivo calcium imaging and molecular genetic manipulation, here we investigate the response patterns and the underlyin...
Poly(3-hydroxyalkanoates) (PHAs) are biodegradable thermoplastics which are accumulated by many bacterial species in the form of intracellular granules and which are thought to serve as reserves of carbon and energy. Pseudomonas putida accumulates a polyester, composed of medium-side-chain 3-hydroxyalkanoic acids, which has excellent film-forming properties. Industrial processing of PHA involve...
Arcelin, a seed protein originally discovered in wild bean accessions, was purified, characterized, and compared to phaseolin, the major seed protein of common bean, and to phytohemagglutinin (PHA), the major bean seed lectin. Arcelin and PHA has several characteristics in common. Both were glycoproteins having similar subunit M(r), deglycosylated M(r), and amino acid compositions. The two prot...
مقدمه: افزایش آلودگی محیط زیست ب ه واسطه مصرف پلاستیکهای سنتزی موجب گرایش به سمت روشهای نوین بیوتکنولوژی برای تولید پلیمرهای تجزیهپذیر شده است. بنابراین، تحقیق حاضر با هدف یافتن باکتریهای بومی تولید کننده PHA به منظور استفاده از آنها در تولید پلیمرهای زیست تخریب پذیر انجام شد. مواد و روش ها: نمونه خاک آلوده به پسماندهای نفتی جمعآوری و پس از غنی سازی اولیه، غربالگری باکتریهای تو...
Lymphocytes from tmsensitized animals or humans damage allogeneic cells in tissue culture when aggregated to the latter by means of phytohemagghtinin (PHA) (1-3). Under the experimental conditions used, injury of the target cells was not seen or was slight in the absence of PHA. When the PHA-treated lymphocytes were separated from the target cells by a Millipore falter, cell damage was prevente...

background and aims: herpes simplex virus (hsv) is responsible for several significant human viral diseases, with severity ranging from subclinical to fatal infection. herpes simplex virus type 2 (hsv2) infections are more commonly seen in association with the genitalia and surrounding areas, and can be transmitted to newborns during childbirth. generalized infections in newborns are also predo...
