Larrea divaricata Cav. is a South American plant widely distributed in Argentina with reported antioxidant and antimicrobial activities. Vitamin C (Vit C) the most important water-soluble antioxidant, is degraded upon factors such as oxygen, heat, light, storage time and temperature, during cooking and in presence of microorganisms. The aim of this work was: to study the antioxidant and antimic...

Chronic pain is very difficult to treat. Thus, novel analgesics are a critical area of research. Strong pre-clinical evidence supports the analgesic effects of α-conopeptides, Vc1.1 and RgIA, which block α9α10 nicotinic acetylcholine receptors (nAChRs). However, the analgesic mechanism is controversial. Some evidence supports the block of α9α10 nAChRs as an analgesic mechanism, while other evid...

The invasive tree Melaleuca quinquenervia (Cav.) Blake is widely distributed throughout peninsular Florida and poses a significant threat to species diversity in the wetland systems of the Everglades. Mitigation of this threat includes the areawide release campaign of the biological control agents Oxyops vitiosa Pascoe and Boreioglycaspis melaleucae Moore. We summarize the results of this relea...

1 Description of the Model We consider an autonomous lawnmower that uses a probability bias to avoid patterns on lawns. This mower is started on a rectangular grassed area. When it reaches the border of the area, it changes its direction. To prevent the mower from following a simple cycle pattern, this direction is randomly biased, such as to ensure that finally the entire area has been cut. A ...

Chick embryos are a great historical research model in basic and applied sciences. Along with other animal models, avian and specifically chicken embryo has been attended, as well. Avian fertilized eggs as a natural bioreactor are an efficient tool for producing recombinant proteins and vaccines manufacturing. Due to the limitations of birds' eggs for viral replication, avian stem cells culture...

One hundred years ago Peyton Rous recovered a virus, now known as the Rous sarcoma virus (RSV), from a chicken sarcoma, which reproduced all aspects of the tumor on injection into closely related chickens. There followed recovery of causal viruses of tumors of different morphology from 4 more of 60 chicken tumors. Subsequent studies in chickens of the biology of the first RSV isolated moved slo...

1 Description of the Model We consider in this test case an extension of the thermostat example described in [1]. A sketch of the model is depicted in Figure 1 There are four modes: Cool, Heat, Check and Error. The latter mode models the occurence of a failure, where the temperature sensor gets stuck at the last checked temperature.The set of variables {t, x, T } where T represents the temperat...

This year, 2015, marked 40 years since the first routine vaccination schedule was approved in Spain. Although the vaccination schedules in the various Autonomous Communities are currently based on that proposed by the Inter-regional Council of the National Health System (CISNS), the differences between them are obvious, not only in terms of the age bands in which particular doses are administer...

Seventeen avian species and two mammalian species were intranasally inoculated with the zoonotic A/chicken/Hong Kong/220/97 (chicken/HK) (H5N1) avian influenza (AI) virus in order to ascertain a relative range of susceptible hosts and the pathobiology of the resultant disease. A direct association was demonstrated between viral replication and the severity of disease, with four general gradatio...

Rat liver cells in vitro were transformed with chicken sarcoma virus B77, giving RL(B77) cells, and with murine sarcoma virus (Harvey), giving RL(MSV) cells. Rat liver cells transformed spontaneously in vitro were designated RL cells. In addition, the RL(MSV) cell line was adapted for growth in culture fluid containing 25 mug of 5-bromodeoxyuridine per ml. All cell lines were tumorigenic in 1-w...
