Electronic Health Records are electronic data generated during or as a byproduct of routine patient care. Structured, semi-structured and unstructured EHR offer researchers unprecedented phenotypic breadth and depth and have the potential to accelerate the development of precision medicine approaches at scale. A main EHR use-case is defining phenotyping algorithms that identify disease status, ...
To extend agricultural productivity by knowledge-based breeding and tailor varieties adapted to specific environmental conditions, it is imperative to improve our ability to assess the dynamic changes of the phenome of crops under field conditions. To this end, we have developed a precision phenotyping platform that combines various sensors for a non-invasive, high-throughput and high-dimension...
Plant phenomics has received increasing interest in recent years in an attempt to bridge the genotype-to-phenotype knowledge gap. There is a need for expanded high-throughput phenotyping capabilities to keep up with an increasing amount of data from high-dimensional imaging sensors and the desire to measure more complex phenotypic traits (Knecht et al., 2016). In this paper, we introduce an ope...
common variable immunodeficiency (cvid) is a heterogeneous heritable disease characterized by arrest in b cell differentiation. an association between cvid and two hla haplotypes, haplotype i (hla-a1, hla-b8, hla-dr3) and haplotype ii (hla-a29, hla-b44, hladr7)has been previously documented. in the present study, we have attempted to find an association between susceptibility to cvid and hla cl...
study of kir expression and hla ligands in cd56+ lymphocytes of drug resistant tuberculosis patients
analysis of receptor–ligand interactions in the context of diseases necessitates to understand how hla–kir genotypes function in diseases. although cd56+ lymphocytes are derived from multiple lineages, they share a functional association with immunosurviellance and antimicrobial responses. the present study aimed to determine whether kir phenotype in cd56 lymphocytes and corresponding...
human leukocyte antigen-g which is an immune tolerance effecter molecule has an important role in the maintenance of fetus during pregnancy. abortion is one of the complications of pregnancy period. in this research, we have studied levels of hla-g 5, hla-g7 isoforms in the abortion-threatened pregnant women in comparison with controls. in a case-control study, 101 abortion-threatened women an...
Background: Natural Killer (NK) cells, through mechanisms such as cytotoxicity and cytokine production, are among the first line of defence against infections. The ability of NK cytotoxicity is related to Killer cell immunoglobulin-like receptors (KIR) found on the cell surface. Interaction between KIRs and human leukocyte antigen (HLA) class I molecules regulate NK cells responses to eliminate...
studies on hla-g, a nonpolymorphic antigen of non-classical hla class i, is of basic and clinical significance. in the present study, the expression of hla-g proteins in the human skin tissue sections of normal and autoimmune pemphigus vulgaris (pv) individuals were investigated using monoclonal antibodies. the antibodies recognized both membrane-bound and soluble isoforms of hla-g. rt-pcr was ...
serology and dna techniques are employed for human leukocyte antigen (hla) typing in different transplant centers. results may not always correlate well and may need retyping with different technique. all the patients (with aplastic anemia, thalassemia, and immunodeficiency) and their donors, requiring hla typing for bone marrow transplant were enrolled in the study. serological hla typing was ...
Background: HLA-G is a nonclassical HLA class I molecule which, when elevated in tumor cells, is one of the main factors involved in tumor evasion of immune responses including NK and T cells. Objective: To evaluate the effect of HLA-G downregulation on NK cell cytotoxicity in tumor cell lines. Methods: The expression level of HLA-G was measured by real-time PCR and flowcytometry after transfec...
