Analyses of the Effects of Arginine, Nicotine, Serotype and Collagen-Binding Proteins on Biofilm Development by 33 Strains of .

serotype strains comprise <3% of oral isolates of but are prominent in diseased cardiovascular (CV) tissue. Collagen binding protein (CBP) genes, and , are prevalent in serotype strains and are associated with endothelial cell invasion. Nicotine increases biofilm formation by serotype strains of , but its effects on serotype strains and strains with CBP are unknown.

Anisotropy of resistivity in hexagonal late transition metals and their alloys.

Transport properties of hexagonal transition metals Co, Ru, and Os at finite temperatures are studied by means of ab initio electronic structure techniques and the Kubo linear response theory. An alloy analogy model for a quantitative treatment of the electrical conductivities due to temperature-induced lattice vibrations (phonons) and spin fluctuations is applied with focus on anisotropy induced by the hexagonal structure. The resistivity anisotropy in Co is found opposite to that in Ru and Os, in agreement with existing experimental data.

[Pitfall cryothermic dermatitis artefacta].

We present four clinicopathological correlated cases of young patients with cryothermic dermatitis artefacta. They were initially misdiagnosed as primary bullous dermatoses or fixed drug eruptions. Cryothermic dermatitis artefacta can imitate authentic dermatoses such as linear IgA bullous dermatosis, herpes virus infection, bullous pemphigoid or fixed drug eruption.

Immune-related pancreatitis associated with checkpoint blockade in melanoma.

Recognizing and treating rare checkpoint inhibitor related adverse events may be a clinical challenge in melanoma therapy. One of rather rare affected organs is the pancreas. Immune-related pancreatitis is difficult to recognize due to its variable clinical characteristics.

Donor Lymphocyte Infusions Used to Treat Mixed-Chimeric and High-Risk Patient Populations in the Relapsed and Nonrelapsed Settings after Allogeneic Transplantation for Hematologic Malignancies Are Associated with High Five-Year Survival if Persistent Full Donor Chimerism Is Obtained or Maintained.

Mixed chimerism (MC), a persistent or increasing number of host cells after allogeneic hematopoietic stem cell transplantation (HSCT), is a predictor of disease relapse. Donor lymphocyte infusions (DLI) have the potential to enhance the graft-versus-malignancy (GVM) effect, reducing the risk of relapse in patients with MC. Hence, in addition to utilizing DLI in the relapsed setting, there is a motivation to pursue pre-emptive DLI for patients in complete remissions after HSCT.

Antiphospholipid autoantibodies as blood biomarkers for detection of early stage Alzheimer's disease.

A robust blood biomarker is urgently needed to facilitate early prognosis for those at risk for Alzheimer's disease (AD). Redox reactive autoantibodies (R-RAAs) represent a novel family of antibodies detectable only after exposure of cerebrospinal fluid (CSF), serum, plasma or immunoglobulin fractions to oxidizing agents. We have previously reported that R-RAA antiphospholipid antibodies (aPLs) are significantly decreased in the CSF and serum of AD patients compared to healthy controls (HCs).

16(th) IHIW: global distribution of extended HLA haplotypes.

This report describes the project to identify the global distribution of extended HLA haplotypes, a component of 16th International HLA and Immunogenetics Workshop (IHIW), and summarizes the initial analyses of data collected. The project aims to investigate extended HLA haplotypes, compare their distribution among different populations, assess their frequency in hematopoietic stem cell unrelated donor registries and initiate an international family studies database and DNA repository to be made publicly available. HLA haplotypes compiled in immunogenetics laboratories during the evaluation of transplant candidates and related potential donors were analysed.

Definitions of histocompatibility typing terms.

Histocompatibility testing for stem cell and solid organ transplantation has become increasingly complex as newly discovered HLA alleles are described. HLA typing assignments reported by laboratories are used by physicians and donor registries for matching donors and recipients. To communicate effectively, a common language for histocompatibility terms should be established.

Definitions of histocompatibility typing terms: Harmonization of Histocompatibility Typing Terms Working Group.

Histocompatibility testing for stem cell and solid organ transplantation has become increasingly complex as newly discovered human leukocyte antigen (HLA) alleles are described. HLA typing assignments reported by laboratories are used by physicians and donor registries for matching donors and recipients. To communicate effectively, a common language for histocompatibility terms should be established.

Redox-reactive antiphospholipid antibody differences between serum from Alzheimer's patients and age-matched controls.

There is no universally acceptable inclusive laboratory biomarker for the diagnosis and staging of neurodegenerative diseases, for example, Alzheimer's. There is an abnormal increase of oxidative stress in the central nervous system (CNS) of Alzheimer's patients that causes oxidation of proteins, lipids and DNA. We have published that the antiphospholipid (aPL) autoantibodies that are members of the redox-reactive autoantibody (R-RAA) family, are significantly decreased or absent in the cerebrospinal fluids of autopsy-confirmed Alzheimer's disease (AD) patients.

Anti-phospholipid antibodies in cerebrospinal fluid but not serum from a boy with psychosis.

A 12-year-old African American boy with mental retardation and Asperger's disorder presented with acute psychosis. Antiphospholipid antibody testing with enzyme-linked immunosorbent assay showed increased levels of immunoglobulin G anticardiolipin antibodies in the cerebrospinal fluid, but not in the serum. Although antiphospholipid antibodies have been reported in the serum of patients with thrombotic and neurologic disorders, there are only a few reports of these antibodies in cerebrospinal fluid.

Spectrum of antiphospholipid antibodies (aPL) in patients with cerebrovascular disease.

Background: The association of stroke and antiphospholipid antibodies (aPL) other than anticardiolipin antibodies (aCL) is not well documented.

Objective: To report the distribution of aCL, antiphosphatidylethanolamine (aPE), and antiphosphatidylserine (aPS) aPL among patients with symptomatic cerebrovascular disease evaluated by our Stroke Service at Indiana University Hospital from January 1997 to November 1999.

Methods: We retrospectively reviewed medical records from 1997 to 1999 at Indiana University Hospital for all patients with symptomatic cerebrovascular disease using the International Statistical Classification of Diseases, 9th Revision, (ICD-9) codes.

Antiphospholipid antibodies in blood and cerebrospinal fluids of patients with psychosis.

Antiphospholipid antibodies (aPL) have been reported in the cerebrospinal fluids (CSF) of neurology patients but no CSF studies with psychiatric patients exist. We tested serum from 100 hospitalized psychotic patients having hallucinations and/or delusions for aPL. Patients with positive serum aPL findings were asked to submit CSF for aPL testing.

Fatal hemorrhagic diathesis associated with mild factor IX deficiency in pl/J mice.

Surgical implantation of devices into the abdomen of PL/J mice was associated with fatal hemorrhage at 9 to 11 d after surgery. Coagulation profiles were evaluated to determine the underlying cause of this effect. The mean activated partial thromboplastin time (aPTT) of untreated PL/J mice was significantly higher than that of BALB/cByJ and C57BL/6J strains.

SNP identification, linkage and radiation hybrid mapping of the porcine lamin A/C (LMNA) gene to chromosome 4q.

The lamins are components of nuclear lamina and they have a profound influence on nuclear structure and functions. They are encoded by three genes, LMNA, LMNB1 and LMNB2. A genomic fragment of the porcine LMNA gene (822 bp; from exons 7 to 9) was amplified by polymerase chain reaction and comparatively sequenced.
