Bone marrow monoclonal small B-cell infiltration (MSBC) associated with monoclonal B lymphocytosis (MBL), is present at a higher frequency in patients with diffuse large B-cell lymphoma (DLBCL). We have prospectively collected blood and bone marrow (BM) samples in patients with primary DLBCL at diagnosis to study the clonal relationship of MBL/MSBC with the paired DLBCL. MBL/MSBC were detected ...

Chronic B-cell lymphocytic leukemia (B-CLL) represents 0.9% of all new cancers. It is estimated that there will be almost 15 000 new cases and 4600 deaths due to CLL in 2015 in the USA.1 The median ages at diagnosis and death are 71 years and 80 years, respectively.1 The criteria that define the diagnosis of B-CLL include the presence of at least 5 × 106 B lymphocytes/L with the peculiar CLL ph...

BACKGROUND Mannose-binding lectin (MBL) is a circulating immune factor responsible for opsonization of pathogens and directly activating complement. Common variations in the MBL gene are responsible for an opsonic deficiency that affects 5% to 7% of whites and are associated with increased susceptibility to infections. After a preliminary report associating these variations with coronary artery...

BACKGROUND Deficiency in clearance of self nuclear antigens, including DNA, is the hallmark of systemic lupus erythematosus (SLE), a chronic autoimmnue disease characterized by the production of various autoantibodies, immune complex deposition and severe organ damage. Our previous studies revealed that administration of syngeneic BALB/c mice with activated lymphocyte-derived DNA (ALD-DNA) coul...

OBJECTIVES The goal of this study was to evaluate bone changes around endosseous implants in partially edentulous patients. MATERIALS AND METHODS A total of 632 two-stage implants were placed in 252 patients. The implants had straight emergence profile, ZirTi surface, 3.3 to 5 mm diameter, and 8.5 to 13 mm length. Bone levels were assessed on orthopantomography immediately after surgery and a...

Mannose-binding lectin (MBL) acts as a serum opsonin in innate immune defense and induces complement activation by the lectin pathway. In humans, low levels of functional serum MBL are caused by the dominant action of three single nucleotide substitutions in exon 1 that disrupt the glycine-rich backbone structure of the protein. The presence of common MBL variant alleles is associated with both...

Many-body localization (MBL) freezes the dynamics of a disordered quantum interacting system, inhibiting thermalization and resulting in persistent memory initial state. Here, with help extensive numerical simulations, authors find slow decay imbalance, quantity often employed experimental studies MBL, even though disorder strength considerably exceeds current estimates position MBL transition....

BACKGROUND Long-term lung allograft survival is limited by bronchiolitis obliterans syndrome (BOS). Mannose binding lectin (MBL) belongs to the innate immune system, participates in complement activation, and may predispose to graft rejection. We investigated mannose binding (MBL) during cold ischemia and in tissue samples from explanted lungs with BOS, and assessed MBL and complement proteins ...

Epidemiological data indicate that acute lymphoblastic leukemia (ALL) could be induced by interactions between the immune system and early childhood infections. Mannose-binding lectin (MBL) plays a critical role in the immune response in early childhood before specific immune protection develops. We investigated whether there may be an association between childhood ALL and low-producing MBL gen...

BACKGROUND Risk factors associated with monoclonal B-cell lymphocytosis (MBL), a potential precursor of chronic lymphocytic leukaemia (CLL), remain unknown. METHODS Using a cross-sectional study design, we investigated demographic, medical and behavioural risk factors associated with MBL. "Low-count" MBL (cases) were defined as individuals with very low median absolute count of clonal B-cells...
