1. A predictive score for COVID-19 diagnosis using clinical, laboratory and chest image data
Abstract Objectives Differential diagnosis of COVID-19 includes a broad range of conditions. Prioritizing containment efforts, protective personal equipment and testing can be challenging. Our aim was to develop a tool to identify patients with higher probability of COVID-19 diagnosis at admission. Methods This cross-sectional study analyzed data from 100

2. Impact of immunological state on eco-physiological variables in one of the southernmost lizards in the world
Abstract: The immune state is an essential component of survival as it directly influences physiological performance and health status. Variation in the leukocyte profile, a significantly increase in body temperature, and a detriment of the eco-physiological performance are among the possible consequences of an unhealthy state. In this study we analyse and

3. Human leukocyte antigen allele linkage disequilibrium and haplotype structure in volunteer bone marrow donors of Paraná State
Abstract Background Bone marrow transplantation has been used in the treatment of various diseases, especially hematologic diseases. The success of this treatment, among other factors, requires human leukocyte antigens (HLA) compatibility between patient and donor. Knowing the human leukocyte antigens allele group and haplotype frequencies as well as the li

4. Lack of association between alopecia areata and HLA class I and II in a southeastern Brazilian population
Abstract: Background: Alopecia areata (AA) is a common disorder of unknown etiology that affects approximately 0.7% to 3.8% of patients among the general population. Currently, genetic and autoimmune factors are emphasized as etiopathogenic. Studies linking Human Leukocyte Antigens (HLA) to AA have suggested that immunogenetic factors may play a role in the

5. Dexamethasone Regulates Macrophage and Cd4+Cd25+ Cell Numbers in the Chicken Spleen
Abstract Dexamethasone (DEX) is a corticoid hormone that is experimentally used to mimic the effects of increased levels of endogenous corticosterone observed during the stress response. Currently, stress is considered one of the major predisposing factors for diseases in the poultry industry. The aim of this study was to analyze the effects of DEX and/or of

6. Hematology and plasma biochemistry of wild-caught Indian cobra Naja naja (Linnaeus, 1758)
Background : Hematology and plasma biochemistry parameters are useful in the assessment and management of snake physiological status. Although reference ranges are readily available for many snake species, they are lacking for most venomous ophidians. We determined hematology and plasma biochemistry reference ranges for the wild-caught Indian cobra, Naja n

7. Frequency of alleles and haplotypes of the human leukocyte antigen system in Bauru, São Paulo, Brazil
Background: HLA allele identification is used in bone marrow transplant programs as HLA compatibility between the donor and recipient may prevent graft rejection. Objective: This study aimed to estimate the frequency of alleles and haplotypes of the HLA system in the region of Bauru and compare these with the frequencies found in other regions of the coun

8. HLA-A*01 allele: a risk factor for dengue haemorrhagic fever in Brazil's population
Severe forms of dengue, such as dengue haemorrhagic fever (DHF) and dengue shock syndrome, are examples of a complex pathogenic mechanism in which the virus, environment and host immune response interact. The influence of the host's genetic predisposition to susceptibility or resistance to infectious diseases has been evidenced in several studies. The associ

9. HLA-A, B and DRB1 allele and haplotype frequencies in volunteer bone marrow donors from the north of Parana state
BACKGROUND: Knowledge of allele and haplotype frequencies of the human leukocyte antigen (HLA) system is important in the search for unrelated bone marrow donors. The Brazilian population is very heterogeneous and the HLA system is highly informative of populations because of the high level of polymorphisms. AIM: The aim of this study was to characterize the

10. HLA-DRB1 alleles in juvenile-onset systemic lupus erythematosus: renal histologic class correlations
Human leukocyte antigens (HLA) DRB1*03 and DRB1*02 have been associated with systemic lupus erythematosus (SLE) in Caucasians and black populations. It has been observed that certain HLA alleles show stronger associations with SLE autoantibodies and clinical subsets, although they have rarely been associated with lupus renal histologic class. In the present

11. Influence of bovine enzootic leukosis on respiratory burst activity of leukocytes / Influência da leucose enzoótica bovina na atividade oxidativa de leucócitos
Different leukocyte populations play key roles on the elimination of foreign antigens through phagocytosis and killing by oxygen-independent and -dependent (respiratory burst) mechanisms. Assuming that Enzootic Bovine Leukosis virus (BLV), that causes a chronic disease, and affects, mainly, lymphoid tissues, alters bovine circulating leukocyte subpopulations

12. Effect of the cysteinyl-leukotrienes on the production of eosinophils in culture of bone marrow: direct actions, mediation of the actions of the indometacina and the aspirin, and regulation of the reply to the PGE2. / Efeitos dos cisteinil-leucotrienos sobre a produção de eosinófilos em cultura de medula óssea: ações diretas, mediação das ações da indometacina e da aspirina, e regulação da resposta à PGE2.
Cysteinyl-Leukotrienes (CysLT) are important mediators of asthma, which induce bronchoconstriction, mucus secretion and a variety of regulatory effects on the infiltrating leukocyte populations, especially eosinophils. Increased CysLT production resulting from the shunting of arachidonic acid towards the 5-lipoxygenase (5-LO) pathway in the absence of active
