In order to determine the absolute configuration of naturally occurring alloxanthin, a HPLC analytical method for three stereoisomers 1a-c was established by using a chiral column. Two authentic samples, (3S,3'S)- and meso-stereoisomers 1b and 1c, were chemically synthesized according to the method previously developed for (3R,3'R)-alloxanthin (1a). Application of this method to various alloxan...
Concentration of blood serum albumin of the round goby Neogobius melanostomus caught in Black Sea and Azov Sea was studied in relation to age, sex, maturation and season. Albumin concentration in fish from Azove Sea was 3-fold higher than in the animals from Black Sea. Albumin level in fish serum depended on fish physiological status, maturation, age, season and geographical location. The varia...
The gobies are non-commercial fishes in the Iranian waters of the Caspian Sea for which population dynamics and stock status are poorly known. In this survey, we tried to define species diversity and catch per unit effort (CPUE) of Gobiidae by using beach seine nets in Salmanshahr, the southern Caspian Sea. From March 2011 to April 2012, 224 specimens representing 4 gobiid species, belonging to...
This study results from a continued investigation of the occurrence and diversity parasites freshwater fish in Solomon Islands. Thus, we revealed new host as well site infection geographical area for cryptogonimid parasite, Stemmatostoma cribbi (Digenea: Cryptogonimidae). The species was identified based on general morphology molecular data metacercariae found gills cleft-lipped goby, Sicyopter...
The chloroform soluble fractions of ethanolic extracts of five Inula belonging to the Compositae family were evaluated for cytotoxic activity against five different cell lines including CACO2 (human colon adenocarcinoma), MCF7 (human breast adenocarcinoma), HEPG2 (human hepatocellular carcinoma), VERO (green African monkey kidney) and WEHI164 (balb c mouse fibrosarcoma). Cytotoxic...
The current monkeypox outbreak reawakens the concern that poxviridae have a high potential for zoonotic spillover and causing a pandemic. Much fieldwork and research have been done by health care and public health workers in Africa during previous human outbreaks, and their knowledge should inform our global response to the current outbreak. However, unusual clinical presentations now have pote...
In an experiment on perceptual learning, monkeys were given the opportunity to watch on television the "private behaviour" of another monkey (which did not know it was being watched.) The subjects were shown monkey X for twenty sessions in a row, followed by monkey Y for twenty sessions, followed by monkey X again fro twenty sessions. The subjects' "interest" in the stimulus monkey remained rou...
Aim The few fish species able to reproduce across wide osmotic ranges either plastically acclimate sperm performance to, or are locally adapted different salinities. invasive round goby (Neogobius melanostomus) is spreading in Eurasia and the Americas, into both fresh brackish water. We aim understand if reproduction salinities affected by an ability acclimate. Location Brackish freshwater syst...
Since the collapse of the pelagic fisheries off southwest Africa in the late 1960s, jellyfish biomass has increased and the structure of the Benguelan fish community has shifted, making the bearded goby (Sufflogobius bibarbatus) the new predominant prey species. Despite increased predation pressure and a harsh environment, the gobies are thriving. Here we show that physiological adaptations and...
