BACKGROUND We previously reported that the fixed-dose combination of isosorbide dinitrate and hydralazine hydrochloride (FDC I/H) significantly decreased the risk of all-cause death and first hospitalization for heart failure (HF) and improved quality of life in patients with New York Heart Association class III or IV heart failure in the African-American Heart Failure Trial (A-HeFT). The curre...

BACKGROUND Storage symptoms, associated with benign prostatic hyperplasia (BPH), often co-exist with voiding symptoms in men with lower urinary tract symptoms (LUTS). Storage symptoms are likely to be most bothersome, and may not be adequately resolved by treatment with α-blocker or antimuscarinic monotherapy. A recent randomised controlled phase 3 trial (NEPTUNE) demonstrated that a fixed-dose...

The production of IgG rheumatoid factors in the inflamed synovium of many patients with rheumatoid arthritis (RA) implies that local sites exist where plasma cell precursors undergo isotype switching and affinity maturation by somatic mutation and selection. Lymphonodular infiltrates of the synovium-containing germinal centers (GCs), are candidates to fulfill such function in the rheumatoid pat...

A case of so-called inflammatory pseudotumor (IPT), occurring in the spleen of a 77-year-old woman, is reported. The spleen contained a well-circumscribed mass with central hemorrhage and necrosis. Histologically, spindle cells were dispersed in a background of abundant inflammatory cells, predominantly lymphocytes and plasma cells. The cells possessed enlarged, sometimes twisted or irregularly...

Follicular dendritic cells (FDC) are non-lymphoid, non-phagocytic, accessory immune cells, crucial for antigen presentation and regulation of the reactions in germinal centers. Sarcoma arising from FDC is very rare it has low-to-intermediate malignant potential. Histopathological examination play a critical role diagnosis disease but difficult cases immunohistochemistry great facilitates misint...

The initial interaction between B cells and follicular dendritic cells (FDCs) appears to be essential for germinal center (GC) formation. To identify molecules regulating this interaction, we generated FDC-staining monoclonal antibodies (mAbs) and screened them for their ability to block FDC-mediated costimulation of growth and differentiation of CD40-stimulated B cells. Using one of the inhibi...

Lymphotoxin (LT)alpha knockout mice, as well as double LTalpha/tumor necrosis factor (TNF) knockout mice, show a severe splenic disorganization with nonsegregating T/B cell zones and complete absence of primary B cell follicles, follicular dendritic cell (FDC) networks, and germinal centers. In contrast, as shown previously and confirmed in this study, LTbeta-deficient mice show much more conse...

Lymph nodes (LN) are secondary lymphoid organs spread throughout the lymphatic system. They function to filter pathogenic material from the lymphatic fluid to maintain the health of the organism. Subcapsular sinus macrophages (SCSM) are among the first-responders within the LN due to their strategic location within the subcapsular sinus region. These macrophages aid the delivery of immune compl...

Considerable progress has been made to identify genetic causation of dilated cardiomyopathy (DCM). DCM is characterized by left ventricular dilatation and systolic dysfunction, and after known causes have been excluded has been termed idiopathic dilated cardiomyopathy (IDC). Studies of IDC that occurs in families, termed familial dilated cardiomyopathy (FDC) provided the initial phenotypic data...
