Objective: Obesity is a major modifiable risk factor for atherosclerosis. Thus, early risk markers are needed to identify obese subjects. The objective of this study was to examine the relationship between body composition and arterial stiffness documented by Doppler-derived renal resistive index (RRI). Materials/Subjects and Methods: We enrolled 120 new-diagnosed hypertensive patients (mean age 45±8 years) who were admitted to our nephrology clinic. Body fat percentage (BFP) was measured by bioelectrical impedance (BIA)...

OBJECTIVE: To investigate the effects of PM2.5 on asthma-related phenotypes and on the expression of TRPA1, V1 protein in lung in a mouse model of asthma. METHODS: Female Balb/c mice were utilized to establish 28 and 42 day asthma models. Mice were sensitized with OVA and challenged with OVA, OVA plus normal saline (NS), or OVA plus PM2.5 at two doses, 1.6 mg·kg(-1) or 8.0 mg·kg(-1). PM2.5 was administrated by intratracheal instillationwithout anesthesia. 24 hours after the final OVA challenge changes in airway resistance (RI) and lung compliance (Cdyn) in response to acetylcholine chloride (ACH) were evaluated, and blood, bronchoalveolar lavage fluid (BALF) and lung tissue samples were taken...

Cell-based approaches, including hepatocyte transplantation and tissue-engineered livers, offer promising alternatives and are expected to help support patients with liver diseases until liver transplantation or recovery via regeneration of the damaged liver. However, the success of cell therapies remains dependent on how well the cells are accepted after transplantation and is directly related to their degree of immunogenicity. In this study, hepatic differentiation of human umbilical cord mesenchymal stem cells (hUC-MSCs) was induced in the traditional monolayer (2D) culture and newly established three-dimensional (3D) aggregation culture with the porcine decellularized liver scaffold (DLS) system (3D-DLS)...

Anti-phospholipid syndrome is an autoimmune disorder characterized by anti-phospholipid antibodies, arterial and venous thrombosis, pregnancy morbidity, and various neurological manifestations including psychiatric disorders. Higher incidence of various autoimmune disorders was found in schizophrenia. In addition, an association between the presence of anti-phospholipid antibodies and schizophrenia or psychosis was previously described, mainly as case reports. Although initially believed to be a result of neuroleptic treatment, the reasons for this association remain obscure...

BACKGROUND: Despite over 6 million subjects contributing to the National Marrow Donor Program human leukocyte antigen (HLA) haplotype frequency reference data (HFD), haplotypes cannot be predicted from the HLA assignments of some patients searching for an unrelated donor (URD) in the Be The Match Registry®. We aimed to determine the incidence of these patient searches and whether haplotypes lacking from the HFD can be found among the low-resolution typed URD pool. MATERIALS AND METHODS: New NMDP searches with uncommon patient haplotypes (UPH), defined as a lack of haplotype pairs in any single ethnic group in the HFD based upon HLA-A˜C˜B˜DRB1˜DQB1, were identified...

Chimerism is defined as the presence of 2 or more than 1 genetically distinct cell populations in an organism. Dispermic chimeras are derived from the fertilization of 1 or 2 matured nuclei by 2 sperms. We here report detection of a healthy and phenotypically normal female with normal ABO red blood cell typing in whom dispermic chimerism was suspected after 3 alleles were identified at multiple human leukocyte antigen (HLA) loci using molecular HLA analysis. Molecular HLA typing showed the donor to have 3 HLA-A, -B, -C, -DRB1, -DQB1 and -DPB1 alleles in blood, saliva and nail samples...

A limitation of solid-phase human leukocyte antigen (HLA) antibody assays is the falsely low/negative result of samples with high-titer antibodies, a phenomenon known as the prozone effect. Here we compared the efficacy of ethylenediaminetetraacetic acid (EDTA) and dithiothreitol (DTT) treatment of serum samples in overcoming the prozone effect. A total of 21 serum samples were treated with either EDTA or DTT before HLA single antigen bead assay. The efficacy of prozone effect reversal, compared with untreated samples, was examined on fourfold, serially diluted samples, from neat to 1:256, using PBS as diluent...

REVIEW
E W Petersdorf
The availability of hematopoietic cell transplantation as curative therapy for blood disorders has been dramatically improved through a better understanding of the human leukocyte antigen (HLA) barrier. Although a fully compatible unrelated donor is preferable, transplantation from donors with a limited degree of HLA mismatching is associated with acceptable outcomes in many cases. Research on the limits of HLA mismatching, and the features that define permissible HLA mismatches will continue to enable transplantation to be more broadly available to patients in need...

BACKGROUND: A catalogue of common and well-documented (CWD) human leukocyte antigen (HLA), previously established by the American Society for Histocompatibility and Immunogenetics (ASHI), is widely used as indicator for typing ambiguities to be resolved in tissue transplantation or for checking the universality of any HLA allele in the world. However, European population samples, which are characterized by a substantial level of genetic variation, are underrepresented in the ASHI catalogue...

Increases in ligand binding to cellular integrins (activation) play an important role in platelet and leukocyte function. Talin is necessary in vivo and sufficient in vitro for integrin αIIbβ3 activation. The precise mechanisms by which talin activates integrin are still being elucidated. In particular, talin undergoes conformational changes (around the F3 helix) and inserts the F3 helix into lipid bilayer; however, the connection between this lipid-inserting mechanism of talin and talin's capacity to activate integrin has never been explored before...

BACKGROUND AND PURPOSE: Aromatic antiepileptic drugs are frequently implicated for cutaneous adverse drug reactions (cADRs); there are case-reports of even severe reactions like drug reaction eosinophilia and systemic symptoms (DRESS) and Stevens Johnson syndrome (SJS)-toxic epidermal necrolysis with Levetiracetam (LEV). Certain human leukocyte antigen (HLA)-alleles have strong association with cADRs due to specific drugs - HLA-B*15:02 and HLA-A*31:01 in Carbamazepine (CBZ)-related SJS in Han-Chinese and European populations, respectively...

Immunotherapy is a promising therapeutic option for patients with non-small cell lung cancer (NSCLC) who do not qualify for surgery. In patients with advanced NSCLC, systemic immune suppression is frequently observed, therefore, researchers are investigating the tumor microenvironment for less invasive and more effective methods of treating lung cancer. Monocytic myeloid-derived suppressor cells (Mo-MDSCs) are potent suppressors of tumor immunity; therefore, this population may significantly impede the application of immunotherapy to treat cancer...

Differentiation induction therapy is an attractive approach in leukemia treatment due to the fact that in blast crisis stage, leukemic cells lose their differentiation capacity. Therefore, it has been proposed as a therapeutic strategy to induce terminal differentiation of leukemic blast cells into a specific lineage, leading to prevention of high proliferation rates. The aim of the present study was to demonstrate the potential of cell differentiation and death induced by bovine dialyzable leukocyte extract (bDLE) in the K562 cell line...

The aim of the study was to examine treatment of cerebral hemorrhages with bone-marrow or human umbilical cord-derived mesenchymal stem cells (BMSCs or Hu-MSCs) and conventional surgical approaches, and determine and compare the effectiveness, feasibility, safety and reproducibility of each method. A retrospective analysis was performed on a cohort of cell-treated cerebral hemorrhage patients from October 1, 2007 to October 1, 2009. A total of 24 patients, all of whom received conventional surgical treatment, were classified as follows: i) The control group consisted of 8 patients who received only hematoma removal surgery, ii) the autologous group consisted of 7 patients who received additional autologous bone marrow mononuclear cell transplantation, and iii) the allograft group consisted of 9 patients who received additional umbilical cord mononuclear cell transplantation...

Few studies have assessed the association of sedentary time with leukocyte telomere length (LTL). In a cross-sectional study conducted in 2012-2013, we examined associations of accelerometer-measured and self-reported sedentary time with LTL in a sample of 1,481 older white and African-American women from the Women's Health Initiative and determined whether associations varied by level of moderate- to vigorous-intensity physical activity (MVPA). The association between sedentary time and LTL was evaluated using multiple linear regression models...

Neutrophils were among the first leukocytes described and visualized by early immunologists. Prominent effector functions during infection and sterile inflammation classically placed them low in the immune tree as rapid, mindless aggressors with poor regulatory functions. This view is currently under reassessment as we uncover new aspects of their life cycle and identify transcriptional and phenotypic diversity that endows them with regulatory properties that extend beyond their lifetime in the circulation...

The endothelial cytoskeleton is a barrier for leukocyte transendothelial migration (TEM). Mononuclear and polymorphonuclear leukocytes generate gaps of similar micron-scale size when squeezing through inflamed endothelial barriers in vitro and in vivo. To elucidate how leukocytes squeeze through these barriers, we co-tracked the endothelial actin filaments and leukocyte nuclei in real time. Nuclear squeezing involved either preexistent or de novo-generated lobes inserted into the leukocyte lamellipodia. Leukocyte nuclei reversibly bent the endothelial actin stress fibers...

Osteosarcomas (OSs) represent a huge challenge to improve the overall survival, especially in metastatic patients. Increasing evidence indicates that both tumor-associated elements but also on host-associated elements are under a remarkable effect on the prognosis of cancer patients, especially systemic inflammatory response. By analyzing a series prognosis of factors, including age, gender, primary tumor size, tumor location, tumor grade, and histological classification, monocyte ratio, and NLR ratio, a clinical predictive model was established by using stepwise logistic regression involved circulating leukocyte to compute the estimated probabilities of metastases for OS patients...
