There is a great scientific debate on homeopathic. However, despite all controversies, it has been observed that homeopathy use among cancer patient is increasing globally. In recent years a homeopathic approach called the „Psorinum‟ therapy have gained tremendous popularity among cancer patients in Kolkata, India. The advocate of this alternative cancer is Dr. Ashim Kumar Chatterjee. However, ...

Biological control is proposed as an ecological strategy to manage the threat of invasive plants, especially in natural areas. To pursue this strategy, we need to know that the host specificity criteria used to evaluate ecological risk with deliberate introduction of an exotic insect for biocontrol are sufficient to predict potential impact on native species. Host specificity is defined by adul...

Abstract Recently, pastoral ecosystem has been strongly studied by naturalists. However, phytoecological research must focus on species richness and enhance these ecosystems. The main objective of this is to prove that the Moroccan very rich in terms soil biodiversity plant formations. In such areas, some plants maintain physicochemical characteristics soil. field experiment was based Braun-Bla...

Aims : We studied the syntaxonomic position, biodiversity, ecological features, nature conservation value and current status of dry grasslands investigated by Josias Braun-Blanquet more than 60 years ago. Study area Inner-alpine valleys Austria. Methods sampled 67 plots 10 m 2 , following standardized EDGG methodology. subjected our to an unsupervised classification with modified TWINSPAN algor...

In this study, the occurrence of the polycyclic musk fragrances HHCB (1,3,4,6,7,8-hexahydro-4,6,6,7,8,8-hexamethylcyclopenta[g]-2-benzopyran) and AHTN (7-acetyl-1,1,3,4,4,6-hexamethyltetrahydeonaphthalene) in marine mammals and sharks collected from Japanese coastal waters is reported. HHCB was present in the blubbers of all finless porpoises (Neophocaena phocaenoides) analyzed (n = 8), at leve...

Mini (15.2 cm) semipermeable membrane devices (SPMDs) were used successfully in 169 streams from six metropolitan areas of the US to sequester hydrophobic organic compounds (HOCs) that are indicative of urbanization. A microscale assay the P450RGS, which responds to compounds that bind to the aryl hydrocarbon receptor (AhR), and the Fluoroscan, a chemical screen for polycyclic aromatic hydrocar...
