primary amyloidosis is a rare disrder wihich is diagnosed by extracellular deposition of proteinaceous material in different organs.in this report,a case of this disease with prominent hepatic involvement is presented.the case is a 63 years old male refered with abdominal enlargement,weight loss,generalized pruritus,anorexia and vague abdominal pain started from six months ago.on physical exami...

in this research, the ability of bacillus strains in suppression of mycelial growth and conidial germination of b. cinerea against botrytis fruit rot of strawberry were evaluated in three cultivars of strawberry including quineliza, paros and kurdistan. results indicated that among 32 strains of bacillus, ten strains showed strong inhibitory effects against b. cinerea using the plate assay and ...

Extracellular soil enzymes are fundamental for the functioning of ecosystems. Several processes in depend on activity these enzymes, including plant decomposition, organic matter formation/mineralization, and nutrient cycling. Moreover, extracellular enzyme occurs is therefore influenced by environmental factors. Due to high sensitivity factors, used monitoring quality. This review aimed presen...

The objective of this study was to isolate halophilic bacteria with the ability to produce intracellular or extracellular L-asparaginase. A total number of 120 halophilic bacteria were isolated from 17 different saline habitats of Iran including salt lakes, wetlands, brine springs and deserts. Among these, 68 were able to grow in the presence of 1.5 M NaCl and 52 demonstrated the ability to gro...

background one group of significant enzymes produced by bacillus genus are alkaline proteases with several important applications in the daily life as well as common industries such as food, detergents, leather, alcohol and beer production and medical and sanitary industries, beside wastewater treatment, , biotransformation, hydrolyzed proteins and oil manufacturing. objectives in this paper, k...

Transforming growth factor beta (TGFβ1, β2, and β3) are 25 kDa disulfide-linked homodimers that regulate many aspects of cellular functions, consist of proliferation, differentiation, adhesion and extracellular matrix formation. TGFβs mediate their biological activities by binding of growth factor ligand to two related, functionally distinct, single-pass transmembrane receptor kinases, known as...

Addiction is a major problem of society. The existing evidences have shown that parental addiction impairs CNS development, learning, and memory. With respect to the role of glutamate in dentate gyrus on learning and memory, in this study, the effect of parental addiction to morphine on extracellular glutamate concentration in dentate gyrus was evaluated. For this purpose, male and female rats ...

Extracellular polymeric substances are defined as high molecular weight compounds secreted by the microorganisms in the surrounding area. Since these extracellular substances are mainly polysaccharide, they are named exopolysaccharide. Microbial exopolysaccharides composed of sugar residue have growing interest as a new class of microbial products which can be used in food, pharmaceutical, and ...

Extracellular Vesicles In article number 2211664, Yuehua Liu, Lin Yu, Liming and co-workers, design a hypoxic treatment strategy to increase extracellular vesicles (EVs) production boost their therapeutic efficacy. An injectable bioactive hydrogel is developed improve the in vivo stability retention of EVs, thereby synergistically accelerating bone regeneration. This simple but effective expect...
