Adaptive medical image encryption algorithm based on multiple chaotic mapping.

Digital images are now widely used in modern clinic diagnosis. The diagnostic images with confidential information related to patients' privacy are stored and transmitted via public networks. Secured schemes to guarantee confidentiality of patients' privacy are becoming more and more vital.

CARDIAC DISORDER IN HEMODIALYSIS: BENEFITS OF CHINESE HERBS.

Background: A major cause of mortality in hemodialysis patients is cardiac disease. Most complementary and alternative therapies, including Chinese herbal medicine, have been useful in the treatment of cardiac disorders.

Materials And Methods: A 46 year old Asian woman with chronic renal failure was admitted to the clinic for hemodialysis.

Changes of QT Dispersion in Hemodialysis Patients after Administrating Zhigancao Decoction ().

Objective: To observe the alteration of QT dispersion (QTd) and QTc dispersion (QTcd) in hemodialysis patients after oral administration of Zhigancao Decoction (, Roasted Licorice Decoction, RLD).

Methods: To investigate the alteration of QTd and QTcd in 68 routine hemodialysis patients before and after hemodialysis with 12-lead electrocardiogram (ECG) after orally administrated RLD for 4 weeks. Blood was also taken for measurement of plasma electrolytes, liver function, renal function, hemoglobin (Hgb) and hematocrit (HCT).

Dihydroartemisinin induces apoptosis of cervical cancer cells via upregulation of RKIP and downregulation of bcl-2.

Treatment of recurrent and metastatic cervical cancer remains a challenge, especially in developing countries, which lack efficient screening programs. In recent years, artemisinin and its derivatives, such as dihydroartemisinin (DHA), which were traditionally used as anti-malarial agent, have been shown to inhibit tumor growth with low toxicity to normal cells. In this study, we investigated mechanisms underlying the anti-tumor effect of DHA in cervical cancer.

Influence of deleted in colorectal carcinoma gene on proliferation of ovarian cancer cell line SKOV-3 in vivo and in vitro.

Objective: To elucidate the effects of the deleted in colorectal carcinoma (DCC) gene on proliferation of ovarian cancer cell line SKOV-3.

Method: An exogenous recombinant eukaryotic expression vector pcDNA3.1(+)-DCC, containing human DCC cDNA coding sequences, was constructed and transfected into SKOV-3 cells (SKOV-3/DCC).

[Growth inhibitory effects of lipofectamine-mediated DCC gene on ovarian epithelial carcinoma].

Objective: To study the inhibitory effects of lipofectamine-mediated deleted colorectal carcinoma gene on ovarian epithelial carcinoma (ovarian cancer) cell line SKOV3.

Methods: We constructed a recombinant eukaryotic expression vector pcDNA3.1 (+)-DCC containing exogenous human DCC cDNA and vector with neomycin resistance gene, which were introduced by lipofectamine-mediated gene transfection into SKOV3 cell line that does not express DCC endogenously, thus forming SKOV3/DCC.
