Studying the evolutionary dynamics of an alien species surviving and continuing to expand after several generations can provide fundamental information on the relevant features of clearly successful invasions. Here, we tackle this task by investigating the dynamics of the genetic diversity in invasive crested porcupine (Hystrix cristata) populations, introduced to Italy about 1500 years ago, wh...

Extraction and study of the optical properties natural dyes from several plant parts such as leaves, flowers, tubers, fruits have been carried out using a simple maceration method UV-Vis absorption characterization. The samples were divided into groups in this study, namely flower group (Tagetes sp., Paeonia Centaure Chrysanthemum Carthamus tinctorius, Gomphrena globosa, Myosotis sylvatica, Lav...

BACKGROUND Lipids in reef building corals can be divided into two classes; non-polar storage lipids, e.g. wax esters and triglycerides, and polar structural lipids, e.g. phospholipids and cholesterol. Differences among algal endosymbiont types are known to have important influences on processes including growth and the photobiology of scleractinian corals yet very little is known about the role...

Background: This study was done to determine the effect of root extract of Acalypha indica Linn (akar kucing) in protecting neuron viability of the rat hippocampus on tissue culture in hypoxic condition. Methods: This is an experimental study of in vitro primary cell culture of hippocampus of Sprague Dowley adult rat. The cultures were group into control (C) and exposure to root extract of Acal...

In the present study, the existence of serotonin immunoreactivity was investigated in the adrenal gland and kidney of porcupine, Hystrix cristata, using immunohistochemical techniques as a pioneer attempt. Serotonin immunoreactivity was detected in adrenal medullary cells, distal tubules and collecting duct cells in kidney.
