We describe the following 8 new genera and 23 new species of Neotropical Exosternini. Conocassis gen. n. (Conocassis minor sp. n. [type species], Conocassis dromedaria sp. n., Conocassis trisulcata sp. n., and Conocassis invaginata sp. n.), Enkyosoma gen. n. (Enkyosoma rockwelli sp. n.), Pluricosta gen. n. (Pluricosta onthophiloides sp. n.), Pyxister gen. n. (Pyxister devorator sp. n. [type spe...

Isoflavonoids are members of the broad class of plant polyphenols that have been shown in vivo to have benefit in the prevention of a wide variety of chronic diseases, including cancer. For genistein (5,7,4'-trihydroxyisoflavone) (GEN), the major isoflavone in soy, reported mechanisms for these biological activities are numerous and include regulation of estrogen-mediated events, inhibition of ...

This study aims to elucidate the epigenetic mechanisms by which genistein (GEN) maintains a normal level of WNT genes during colon cancer development. We have reported that soy protein isolate (SPI) and GEN repressed WNT signaling, correlating with the reduction of pre-neoplastic lesions in rat colon. We hypothesized that SPI and GEN induced epigenetic modifications on Sfrp2, Sfrp5 and Wnt5a ge...

We studied the role of the C5b-9 membrane attack complex in two models of inflammatory glomerulonephritis (GN) initiated by acute glomerular endothelial injury in Piebold-viral-Glaxo (PVG) complement-sufficient rats (C+), C6-deficient rats (C6-), and rats systematically depleted of complement with cobra venom factor (CVF). GN was induced by performing a left nephrectomy and selectively perfusin...

Nonresolving inflammation in the intestine predisposes individuals to colitis-associated colorectal cancer (CAC), which leads to high morbidity and mortality. Here we show that genistein-27 (GEN-27), a derivative of genistein, inhibited proliferation of human colorectal cancer cells through inhibiting β-catenin activity. Our results showed that GEN-27 increased expressions of adenomatous polypo...

BACKGROUND Genistein (Gen) exhibits anti-mutagenic and anti-metastatic activities in hepatoma cell lines. Gen has suppressive effects on tumor growth and angiogenesis in nude mice. Gen suppresses the enzymatic activity of matrix metalloproteinase (MMP)-9; however, the mechanism underlying its anti-invasive activity on hepatocellular carcinoma (HCC) cells is unclear. METHODS In this study, the...

Potential benefits of combination antibiotic therapy for the treatment of plague have never been evaluated. We compared the efficacy of a ciprofloxacin (CIN) and gentamicin (GEN) combination therapy with that of each antibiotic administered alone (i) against Yersinia pestis in vitro and (ii) in a mouse model of bubonic plague in which animals were intravenously injected with antibiotics for fiv...

Biological photoreceptors transduce and communicate information about visual stimuli to other neurons through a series of signal transformations among physical states such as concentration of a chemical species, current, or the number of open ion channels. We present a communication channel model to quantify the transmission and degradation of visual information in the blowfly photoreceptor cel...

This study investigated the effects of perinatal genistein (GEN) exposure on the central nervous system of rat offspring. Pregnant dams orally received GEN (1 or 10 mg/kg/day) or vehicle (1 ml/kg/day) from gestation day 10 to postnatal day 14. In order to assess the effects of GEN on rat offspring, we used a battery of behavioral tests, including the open-field, elevated plus-maze, MAZE and ste...

Gen X, Y and Z are labeling the name of a generation with certain year birth unique character each. Differences in perspectives on how to conduct communication between superiors subordinates position structure this bureaucracy interesting things study. The theory organizational culture is reference examining these three generations interpret within organization through performances that occur t...
