are of the greatest interest and importance; yet it must be confessed that attention has been paid to them by obstetricians only of recent years, and our knowledge is as yet of the scantiest description. The reason for this has probably been that the interest in such cases has been divided, the obstetrician being specially concerned with the clinical features, and only languidly hitherto in the...

acrjourna h levels of the critical p53 inhibitor Mdm4 is common in tumors that retain a wild-type p53 allele, ting that Mdm4 overexpression is an important mechanism for p53 inactivation during tumorigenesis. t this hypothesis in vivo, we generated transgenic mice with widespread expression of Mdm4. Two ndent lines of transgenic mice, Mdm4 and Mdm4, developed spontaneous tumors, the most prevf ...

Downlo an epidermal growth factor receptor 2 (HER2) overexpression stimulates cell growth in p53-mutated hile it inhibits cell proliferation in those with wild-type p53, but the molecular mechanism is wn. The Dmp1 promoter was activated by HER2/neu through the phosphatidylinositol-3′-kinaseF-κB pathway, which in turn stimulated Arf transcription. Binding of p65 and p52 subunits of was shown to ...

Hydatidiform moles are abnormal conceptions characterised by atypical hyperplastic trophoblasts and hydropic villi. Their incidence is approximately 1 in 1000 pregnancies. The recurrence risk of hydatidiform mole is approximately 1 in 60 in a subsequent pregnancy and 1 in 6.5 in the third pregnancy. In cases with recurrence, the majority of moles are of the same type as that in the preceding pr...

Moringa oleifera Lam (Moringaceae) is promising plant for biomedicine applications because it has an impressive range of medicinal purposes with high nutritional value. Therefore, we investigated the therapeutic effect of Moringa oleifera leaf extract (MOLE) on Ehrlich's solid tumor implanted mice (EST-mice). Swiss male albino mice were implanted intramuscularly with Ehrlich ascites carcinoma (...

Growing cultures of Streptococcus faecalis at temperatures above 30 C have activation energies for both rates of growth and glycolysis of 10.3 kcal mole(-1), and a constant growth yield; when growth takes place below this temperature, the growth yield decreases and the activation energy for growth increases to 21.1 kcal mole(-1), but the activation energy for glycolysis is unchanged. The adenos...

The naked mole-rat (Heterocephalus glaber) is a subterranean eusocial rodent with a markedly long lifespan and resistance to tumorigenesis. Multiple data implicate modulation of protein translation in longevity. Here we report that 28S ribosomal RNA (rRNA) of the naked mole-rat is processed into two smaller fragments of unequal size. The two breakpoints are located in the 28S rRNA divergent reg...

Naked mole-rats are highly social and strictly subterranean rodents that live in large communal colonies in sealed and chronically oxygen-depleted burrows. Brain slices from naked mole-rats show extreme tolerance to hypoxia compared to slices from other mammals, as indicated by maintenance of synaptic transmission under more hypoxic conditions and three fold longer latency to anoxic depolarizat...

BACKGROUND/AIMS The maximum lifespan of the naked mole rat is over 28.3 years, which exceeds that of any other rodent species, suggesting that age-related changes in its body composition and functionality are either attenuated or delayed in this extraordinarily long-lived species. However, the mechanisms underlying the aging process in this species are poorly understood. In this study, we inves...

Naked mole-rats are fossorial African rodents that live in large, eusocial groups. Adult subordinate female mole-rats are reproductively suppressed by the dominant breeding female in their colonies. As a result, subordinate females remain reproductively quiescent for their entire lives unless they are removed from the suppressive presence of the dominant female. This makes subordinate female mo...
