Abstract Introduction One of the most important health problems today is cancer. The aim this study was to investigate in vitro effect yarrow (Y) with known anticarcinogenic on Ehrlich ascites tumor (EAT). Materials and Methods above-ground part (300 g) Y macerated water extracted three times for 24 hours at 37°C a shaking bath. In study, EAT cells were divided into control, DMSO group 5-FU, 50...

BACKGROUND Possibly due to the small size of the olfactory bulb (OB) as compared to rodents, it was generally believed that songbirds lack a well-developed sense of smell. This belief was recently revised by several studies showing that various bird species, including passerines, use olfaction in many respects of life. During courtship and nest building, male European starlings (Sturnus vulgari...

1. Trade-offs between reproduction and growth are central assumptions of life-history theory, but their implications for sexual size dimorphism (SSD) are poorly understood. 2. Adult male Yarrow's spiny lizards Sceloporus jarrovii average 10% larger than adult females. In a low-altitude (1700 m) population, this SSD develops because males grow more quickly than females during the first year of l...

Data on the bionomics of Dryudella stigma (Panzer, 1809) in Poland are presented. The larva is described for first time a European , and second world with only D. immigrans before. egg stage lasts 2–3 days, larval 11–14 days. praepupal longest overwinters cocoon from mid-July to end May. female provisions an average seven bug nymphs per cell, mainly Aelia acuminata (Linnaeus, 1758) (Pentatomida...

The current study aimed to develop carbomer based hydrogel dressings, incorporating ethanolic extracts of Rosmarinus officinalis aerial parts, Achillea millefolium and Calendula flowers. pharmaceutical properties the obtained hydrogels, as well their texture antimicrobial activity, were further evaluated. Five wound dressing formulations on carbopol prepared. addition formulation slightly lower...
