PURPOSE Secreted Frizzled Related Proteins (SFRPs) are soluble molecules capable of modulating Wnt signalling. Different lines of evidence indicate that SFRP activity is related with the development and function of the retina photoreceptor cells as well as with their apoptotic degeneration associated with the onset of different cases of retinal dystrophy (RD). Because the genetic causes of many...

We investigated how experience regulates the structure of a defined neuronal circuit in adult mice. Enriched environment (EE) produced a robust and reversible increase in hippocampal stratum lucidum synapse numbers, mossy fiber terminal (LMT) numbers, and spine plus synapse densities at LMTs, whereas a distinct mechanism depending on Rab3a promoted LMT volume growth. In parallel, EE increased p...

intoduction: acute myeloid leukemia (aml) is a heterogeneous group of hematologic malignancies with abundant changeability in the pathogenesis. dna methylation of cpg islands within the promoters of specific genes may play roles in tumor initiation and progression. secreted frizzled-related proteins (sfrps) are negative regulator of the wnt signaling pathway. in the present study, we examined t...

The work deals with the fatigue lifetime estimation of Short Fiber Reinforced Thermoplastics (SFRP), a focus on conjugated effects thermal aging. Two materials containing 35% (V35) and 50% (V50) weight ratio short glass fibers were aged for 500 h at 200°C in air compared to same Dry-As-Molded (DAM) state. Monotonic tests performed samples machined out injected plates cut along three different o...

background: regarding that accurate diagnosis of human hydatidosis still needs more investigations, the present study was conducted to clone, express, and evaluate the gene encoding agb subunits (egagb16 kda) from echinococcus granulosus (iranian g1 strain) and its evaluation by elisa test. methods: dna was extracted from protoscoleces and was utilized by pcr for strain identification. total rn...

Effect of Recombinant Human Granulocyte Colony–Stimulating Factor for Patients With COVID-19 and Lymphopenia

objective: multiple myeloma (mm) is a plasma cell malignancy where plasma cells are increased in the bone marrow (bm) and usually do not enter peripheral blood, but produce harmful factors creating problems in these patients (e.g. malignant plasma cells over activate osteoclasts and inhibit osteoblasts with factors like rankl and dkk). these factors are a main cause of bone lesion in mm patient...

Background: The potential of plants, as a safe and eukaryotic system, is considered in the production of recombinant therapeutic human protein today; but the expression level of heterologous proteins is limited by the post-transcriptional gene silencing (PTGS) response in this new technology. The use of viral suppressors of gene silencing can prevent PTGS and improve transient expression level ...

objective: influenza virus a (h1n1) is an important subtype of the influenza respiratory viruses, which has important worldwide implications. hemagglutinin (ha), an important viral antigen, is responsible for binding to human cell receptors leading to an onset of the disease process. considering the critical role of viral attachment, this study focuses on the extraction and cloning of ha and it...

The recombinant antibodies AC650, AC653, AC656 and AD460 detect by immunofluorescence the human CD8α protein.
