Gray-zone lymphoma (GZL) with features intermediate between classic Hodgkin lymphoma (cHL) and large B-cell lymphoma (LBCL) was introduced as a provisional entity into the World Health Organization classification in 2008. However, as diagnostic criteria are imprecise, reliable identification of GZL cases remains challenging. Here, we describe the histopathologic features of 139 GZL cases from a retrospective Lymphoma Study Association (LYSA) study with the goal to improve classification accuracy. Inclusion criteria were based on literature review and an expert consensus opinion of the LYSA hematopathologist panel...

BACKGROUND: Hepatitis B and C are diseases with high morbimortality and constitute a global public health problem. In Brazil, the prevalence is not homogeneous, oscillating among different regions, but it is estimated that currently about 1% of the population present chronic disease related to the B virus and that there are 1.5 million infected with the C virus. Despite the development of hepatitis B vaccine, improvement in diagnostic methods and therapeutic advances in the field of viral hepatitis, there is still a large number of people who continues to be infected by these viruses, especially in populations at risk and also due to several factors, including vaccination and migration policies...

Neurodegenerative disorders are often associated with cellular dysfunction caused by underlying protein-misfolding signalling. Numerous neuropathologies are diagnosed at late stage symptomatic changes which occur in response to these molecular malfunctions and treatment is often too late or restricted only to the slowing of further cell death. Important new strategies to identify early biomarkers with predictive value to intervene with disease progression at stages where cell dysfunction has not progressed irreversibly is of paramount importance...

Anti-C1q autoantibodies may be found in many conditions, most commonly in systemic lupus erythematosus (SLE) and hypocomplementemic urticarial vasculitis syndrome (HUVS), and are diagnostic markers as well as disease activity markers in lupus nephritis. Sera from patients with SLE and HUVS show partly distinct autoantibody reactivities to separated protein chains B and C of the first component of complement, C1q. These different binding specificities can be detected by Western blot analysis of the autoantibodies under reducing conditions...

Immunohistochemistry (IHC) is a powerful technique that exploits the specific binding between an antibody and antigen to detect and localize specific antigens in cells and tissue, most commonly detected and examined with the light microscope. A standard tool in many fields in the research setting, IHC has become an essential ancillary technique in clinical diagnostics in anatomic pathology (Lin F, Chen Z. Arch Pathol Lab Med 138:1564-1577, 2014) with the advent of antigen retrieval methods allowing it to be performed conveniently on formalin fixed paraffin embedded (FFPE) tissue (Taylor CR, Shi S-R, Barr NJ...

Genomics and bioinformatics are increasingly contributing to our understanding of infectious diseases caused by bacterial pathogens such as Mycobacterium tuberculosis and parasites such as Plasmodium falciparum . This ranges from investigations of disease outbreaks and pathogenesis, host and pathogen genomic variation, and host immune evasion mechanisms to identification of potential diagnostic markers and vaccine targets. High throughput genomics data generated from pathogens and animal models can be combined with host genomics and patients' health records to give advice on treatment options as well as potential drug and vaccine interactions...

Background: The diagnosis of myalgic encephalomyelitis (ME/CFS) in research and clinical practice has largely relied on clinical history, which can be subjective in nature. Clinical signs are often subtle, overlap with other conditions, and are not formally included as part of diagnostic workup. The characterization of clinical signs and biomarkers is needed for better diagnosis and classification of patients and to monitor treatment response. Hand grip strength (HGS) has been used as an objective measure of muscle strength and fatigue, which is a primary symptom of ME/CFS...

Fluorouracil (5-FU) is the first-line chemotherapeutic drug for cholangiocarcinoma (CCA), but its efficacy has been compromised by the development of resistance. Development of 5-FU resistance is associated with elevated expression of its cellular target, thymidylate synthase (TYMS). E2F1 transcription factor has previously been shown to modulate the expression of FOXM1 and TYMS. Immunohistochemical (IHC) analysis revealed a strong correlated upregulation of FOXM1 (78%) and TYMS (48%) expression at the protein levels in CCA tissues...

Leptospirosis is a global zoonosis caused by pathogenic Leptospira. Neutrophils are key cells against bacterial pathogens but can also contribute to tissue damage. Since the information regarding the role of human neutrophils in leptospirosis is scant, we comparatively analyzed the human neutrophil's response to saprophytic Leptospira biflexa serovar Patoc (Patoc) and the pathogenic Leptospira interrogans serovar Copenhageni (LIC). Both species triggered neutrophil responses involved in migration, including the up-regulation of CD11b expression, adhesion to collagen and the release of IL-8...
