Background
Dendritic cells (DCs) promote pathogen recognition, uptake and presentation of antigen through DC-specific intercellular adhesion molecule 3-grabbing non-integrin (DC-SIGN) and toll-like receptors (TLRs).Aims and Objectives
We aimed to study temporal changes in DCs, TLRs and DC-SIGN during acute viral hepatitis B (AVHB) infection and compare them to chronic (CHB) and to investigate the earliest time point of activated pathogen recognition receptors in hepatitis B viral infection.Methods
We measured the frequencies of circulating myeloid (mDC) and plasmacytoid (pDC) dendritic cells and IFN-α production along with the expression of DC-SIGN and Toll Like Receptors (TLR's) in HBV patients at different time points. Also investigated in healthy volunteers, the dynamic changes in TLRs expression after receiving hepatitis B vaccine.Results
On follow-up of AVHB patients, we found the mDC population was significantly higher at week 4 and 6 (p < 0.02, 0.01), whereas the pDC population was unchanged at week 6 compared with week 0. Whereas frequencies of mDCs and pDCs were found to be elevated in AVHB and CHB patients than HC (p < 0.00 and 0.01, respectively) but was comparable among AVHB vs CHB. The DCs in CHB patients were functionally impaired with significantly low IFN-α production and low DCSIGN expression (p < 0.04 and 0.00, respectively). Even after stimulation by TLR agonists, no change was found in IFN-α production in CHB patients. MyD88 and IL-6, IFN-α mRNA levels were also found down-regulated. Interestingly, on follow-up after HBV vaccine, TLRs expression was found high at day 3 after vaccination.Discussion
The initial events of immune activation might be responsible for modulating immune response. These novel observations would pave the way for the development of antiviral strategies for chronic HBV infection.3.

We report three-dimensional echocardiographic delineation of a congenital aneurysm of the membranous interventricular septum causing right ventricular outflow tract obstruction in an adult patient. To our knowledge, these findings have not been described before. 相似文献

Right coronary artery to coronary sinus fistula is a rare anomaly. We present a unique case of an adult patient with multiple fistulae from the right coronary artery draining into the coronary sinus near the posterior left atrium-left ventricle junction, first suspected by transthoracic two-dimensional echocardiography. The multiple openings were not seen by any invasive or noninvasive techniques and were noted only at the time of surgery. To our knowledge, this is the first case of multiple fistulae connecting the right coronary artery to the coronary sinus that has been reported in the English literature. 相似文献

Combined tumors showing histologic features of both ependymoma and subependymoma have been described. In this report we present a case of combined tanycytic ependymoma with foci of subependymoma (WHO grade II), occurring in a 40 year‐old male, which arose in the wall of the lateral ventricle. The tanycytic ependymoma component showed elongated fibrillary cells with a fascicular pattern of growth, while the subependymoma component showed clustered cell bodies surrounded by a fibrillary stroma with a microcystic appearance. We consider the present case to be an unusual example of tanycytic ependymoma; which to the best of our knowledge has not been associated with a subependymoma. 相似文献

A Phase II multicentric study was carried out to compare the different contraceptive treatment schedules of the monthly injectable consisting of norethisterone oenanthate (NET OEN) 50 mg either given alone or in combination with estrogen esters, 2.5 or 5 mg of estradiol valerate (E2 Val.) or estradiol cypionate (E2 Cyp.). A total of 364 women were observed for 1686 months of use. Analysis of the bleeding pattern data indicated that NET OEN 50 mg when given alone gave rise to delayed cycles and/or amenorrhoea. However, the addition of estrogen esters in a dose of either 2.5 or 5 mg provided significantly better bleeding patterns. Of the different treatment schedules investigated, the combination of NET OEN 50 mg with E2 Val. 5 mg provided more consistent and better cycle control. These findings however need further validation on a larger study sample. 相似文献
