The purpose of the present study was to identify, by gas chromatography (GC) and GC-mass spectrometry (GC-MS), components spontaneously emitted volatile organic compounds (VOCs), obtained Solid-Phase-Micro-Extraction (SPME) that hydrodistilled oil fresh flowers leaves Ononis natrix, as well compare them. leaf rich in non-terpenoid aldehydes, whereas its aroma profile contained mainly sesquiterp...

The difficulty to detect invasive species depends of numerous factors, such as morphological similarities with local taxa (Dubey et al., 2014), low densities (Fitzpatrick et al., 2009), cryptic behaviours (Mazzotti et al., 2015), or remote distribution ranges (Lass et al., 2002). In some circumstances, alien taxa hybridize with local ones resulting in individuals with intermediate phenotypes. T...

Present study was designed to examine daily and seasonal variability in the innate immune responses of splenocytes in the fresh water snake, Natrix piscator. Animals were mildly anesthetized and spleen was aseptically isolated and processed for macrophage phagocytosis, NBT reduction, nitrite production, splenocyte proliferation and serum lysozyme activity. Samples were collected at seven time p...

The majority of snake bites in Central America are caused by Bothrops asper, whose venom induce complex local effects such as myonecrosis, edema and especially hemorrhage. These effects are only partially neutralized by the clinically used antivenom, even when administered rapidly after envenomation. Recently we screened 49 substances for antihemorrhagic activity and found that a mixture compos...

Since the early papers of Bohr & Hasselbalch (1900, 1903) and Murray (1925), considerable information concerning the growth and metabolic processes in the avian embryo has been accumulated (Romanoff, 1967). Respiratory and growth processes during embryonic life in many species of fishes, amphibians and mammals are also fairly well known. Only a few studies have been reported, however, on the me...
