The objective of the paper was to study the anti-tumor effect of total glycosides from Radix paeoniae rubra in S180 tumor-bearing mice, and to preliminarily explore its mechanism of action. Mice were made into S180 solid tumor model, grouped and administered with the extracts; tumor inhibition rate was measured by harvesting the tumors, and serum IL-2 and IL-4 levels were measured by taking blo...

Mutualistic fungal endophytes infect many grass species and often confer benefits to the hosts such as reduced herbivory by insects and animals. The physiological interactions between the endophytes and their hosts have not been well characterized. Fungal-secreted proteins are likely to be important components of the interaction. In the interaction between Poa ampla and the endophyte Neotyphodi...

Studies of euryhaline crustaceans have identified conserved osmoregulatory adaptions allowing hyper-osmoregulation in dilute waters. However, previous studies have mainly examined decapod brachyurans with marine ancestries inhabiting estuaries or tidal creeks on a seasonal basis. Here, we describe osmoregulation in the atyid Halocaridina rubra, an endemic Hawaiian shrimp of freshwater ancestry ...

Antipyretic effect of ethanolic extract of the leaf of plumeria rubra was investigated. Intraperitoneal administration of boiled milk at a dose 0.5 ml/kg body weight in albino rabbit leads to pyrexia. Intraperitoneal (i. p. route) administration of ethanolic extract of the leaf of plumeria rubra at a dose 200mg/kg body weight were shown significantly reduce the elevated body temperature of rabb...

Coronary artery bypass surgery for coronary artery thrombosis in patients with polycythaemia rubra vera has been rarely described. The main issue with such patients is their risk of both bleeding and thrombosis and as such the ideal postoperative management of such cases is unknown. Hereby, we describe a case of a 62-year-old man with polycythaemia rubra vera who underwent coronary artery bypas...

We synthesized a series of fluorinated compounds and tested them in an easy assay for their repellent activity against the ant Myrmica rubra. Depending on their chain length and pattern of fluorination these molecules are efficient repellents for this ant. Fluorinated compounds are stronger repellents than their unfluorinated analogs. 1,1,1-Trifluorotridecan-2-one (4) is an even better repellen...

No aspect of speciation is as controversial as the view that new species can evolve sympatrically, among populations in close physical contact. Social parasitism has been suggested to yield necessary disruptive selection for sympatric speciation. Recently, mitochondrial DNA phylogeography has shown that the ant Myrmica microrubra is closely related to its host, Myrmica rubra, leading to the sug...
