Disorders of sex development (DSD) are rare in cats. They can be caused by chromosomal aberrations, gene mutations or other undefined factors. The aim of the present study was to compare the histological structure and immunohistochemical reactivity of testes in cats with DSD and in healthy cats. The research material consisted of the gonads of four cats - phenotypic males with an incorrect structure of the reproductive system. The control group consisted of the testes of four healthy cats - routinely castrated phenotypical males...

Autoimmune neurological diseases are an important group of pathologies in neuropaediatrics. The central nervous system was considered to be an immunologically privileged organ, as it protects itself from the surroundings by means of the blood-brain barrier. In recent years, however, reports have been published of a growing number of disorders produced by antibodies that react against neuronal or glial proteins and give rise to a wide variety of clinical conditions (epilepsy, encephalopathy, movement disorders, etc...

Technological innovations in vaccinology have recently contributed to bring about novel insights for the vaccine-induced immune response. While the current protocols that use peripheral blood samples may provide abundant data, a range of distinct components of whole blood samples are required and the different anticoagulant systems employed may impair some properties of the biological sample and interfere with functional assays. Although the interference of heparin in functional assays for viral neutralizing antibodies such as the functional plaque-reduction neutralization test (PRNT), considered the gold-standard method to assess and monitor the protective immunity induced by the Yellow fever virus (YFV) vaccine, has been well characterized, the development of pre-analytical treatments is still required for the establishment of optimized protocols...

INTRODUCTION: The ultimate aim of pretransfusion testing is the acceptable survival of donor red cells in recipient's body and antibody detection plays a critical role in achieving the same. The cornerstone of antibody detection method is detecting an unexpected antibody as against the expected antibodies of ABO blood group system. Autoantibodies can also interfere with the detection of clinically significant alloantibodies. AIM: To study the frequency of alloantibodies and autoantibodies in the healthy blood donors and patient population visiting our hospital...

Systemic lupus erythematosus (SLE) is a prototypic systemic autoimmune disease. Tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL) is cytotoxic to a wide variety of transformed cells, but not to most normal cells. This study measures serum levels of tumor necrosis factor (TNF)-α, interleukin (IL)-6 and 10 and soluble TRAIL (sTRAIL) in patients with SLE and assesses their relation to severity of the disease. The study included 70 SLE patients and 20 healthy controls. Patients were diagnosed according to criteria proposed by the American Rheumatism Association for classification of SLE and disease activity was scored using the British Isles Lupus Assessment Group (BILAG-2004)...

Improved awareness of the hepatitis C virus (HCV) transmission has contributed to the overall decline in the HCV infection rate in some developing countries including Thailand. Chronic HCV infection in some rural Thai communities, however, presents a challenge in the efforts to treat and manage HCV-related diseases. Published and unpublished studies have suggested an unusually high incidence of HCV infection in a Thai province of Phetchabun compared to elsewhere in Thailand. To determine the magnitude of HCV infection and identify potential factors contributing to the higher rate of HCV infection in this province, we performed a population-based study in Phetchabun (n = 1667) and the neighboring Khon Kaen province (n = 1410) where HCV prevalence is much lower...

We investigated whether lupus nephritis (LN) patients could be distinguished based on the time of disease onset and, if so, whether the groups differed in their clinical and laboratory features and long-term prognosis in ethnically homogeneous Korean patients. We enrolled 117 systemic lupus erythematosus patients with available clinical data at the time of renal biopsy of LN. Sociodemographic, clinical, and laboratory data and concomitant diseases were evaluated at the time of renal biopsy. We divided LN patients, according to age at LN diagnosis, into three groups: juvenile-onset LN (JLN, diagnosed at ≤18 years), adult-onset LN (ALN, diagnosed at 18-50 years), and late-onset LN (LLN, diagnosed at >50 years) and compared demographic, clinical, histological, and laboratory findings...

Guillain-Barré syndrome (GBS) is an acute polyradiculoneuropathy with a highly variable clinical presentation, course, and outcome. The factors that determine the clinical variation of GBS are poorly understood which complicates the care and treatment of individual patients. The protocol of the ongoing International GBS Outcome Study (IGOS), a prospective, observational, multi-centre cohort study that aims to identify the clinical and biological determinants and predictors of disease onset, subtype, course and outcome of GBS is presented here...

BACKGROUND: Corneal xenotransplantation is an effective solution for the shortage of human donor corneas, and the porcine cornea may be a suitable candidate for the donor cornea because of its optical similarity with humans. However, it is necessary to administer additional immunosuppressants to overcome antigenic differences. We aimed to investigate the feasibility of porcine corneas with anti-CD40 antibody-mediated costimulation blockade in a clinically applicable pig-to-non-human primate corneal xenotransplantation model...

BACKGROUND: Studies suggest that free-ranging bottlenose dolphins exhibit a suppressed immune system because of exposure to contaminants or microorganisms. However, due to a lack of commercially available antibodies specific to marine mammal immune cell surface markers, the research has been indecisive. The purpose of this study was to identify cross-reactive terrestrial-specific antibodies in order to assess the changes in the immune cell populations of dolphins under human care and free-ranging dolphins...

Low antigenic expression of ABO subgroup system on red blood cell (RBC) is cause of discrepancy between forward and reverse blood typing in the standard agglutination technique. Neutralization agglutination is employed for verification of the detection of ABH substances in saliva. However, the neutralization technique is complicated, time-consuming and requires expertise. To overcome these drawbacks, surface plasmon resonance (SPR) imaging was developed for ABH antigen detection on RBCs and in saliva. An antibody array was designed to classify the ABO subgroups by anti-A, anti-B, and anti-H antibodies; the array was immobilized on a carboxymethyl-dextran sensor-surface...
