Our evolutionary heritage regarding food choice and food preferences is responsible for the mismatch with the food environments we have created, which leads to problems such as overweight and obesity. Several hypotheses have attempted to explain the high rate of obesity present in today’s world. The thrifty genotype hypothesis suggested that obesity today is a throwback to our ancestors having undergone positive selection for genes that favored energy storage. The drifty genotype hypothesis contends that the prevalence of thrifty genes is not a result of positive selection for energy-storage genes but, rather, is attributable to genetic drift resulting from the removal of predatory selection pressures. Both hypotheses focus on environmental changes over time, positive selection and genetic drift. While genetics plays a significant role, we believe that cultural selection is also responsible for the spread of obesogenic phenomena in Albania. The high rates of overweight and obesity among Albanians today can be explained as a mismatch between our evolutionary past and maladaptive behaviors.","PeriodicalId":9116,"journal":{"name":"Bollettino della Societa italiana di biologia sperimentale","volume":"42 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85453129","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Gas exchange parameters revealed different strategies of maize under the stress. In our study, most of the temperate hybrids maintained open stomata to keep a higher photosynthesis rate at the beginning of stress, while the other hybrids decreased stomatal conductance. Compared to temperate maize, the tropical maize had higher antioxidase activity and greater physiological parameter variation among hybrids. KS5731 and ZD309 had stronger drought resistance among tropical and temperate maize hybrids separately. Tolerant hybrids maintained active photosynthesis, have higher osmotic adjustment ability and antioxidase activities but lower malonaldehyde content than the sensitive ones. Our results led to a better understanding of the physiological responses of tropical and temperate maize plants to drought stress and may provide an insight of breeding for drought resistance in maize.","PeriodicalId":9116,"journal":{"name":"Bollettino della Societa italiana di biologia sperimentale","volume":"15 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79061896","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study of animal behavior patterns in response to environmental stress/threats, is a relatively new and unexplored topic. The aim of this study is to offer a modest contribution in explaining the effects of pharmaceutical pollutants found in freshwater ecosystems, using the behavior patterns and physiology of Carassius auratus. Behavior changes were evaluated through swimming patterns, opercula and pectoral response, and rheological aggressivity. Animals were exposed for 5 weeks to water (as control), ethanol (EtOH, 0.25 and 1%, v/v), fluoxetine (FLX, 100 μg/L) and caffeine (CAF, 50 mg/L) and their short-term responses were recorded. The video has been analyzed using the open-sourced software program Track3D and EthoVision XT, which objectively quantified swimming and social behaviors. In all treatments, fish showed significantly (P<0.01) high level of stress, aggressivity and hyperactivity, compared to control. An interesting fact was that for each pollutant, fish exhibited different swimming patterns, from the normal one. These changes in the nervous system such as stressed behavior, irregular swimming patterns, hyperactivity and aggression, are consequences of pharmaceutical pollution in freshwater bodies and as such they can be used as suitable early physiological response biomarkers to environmental stress. Monitoring of altered behavior is a great early indicator of water pollution, which can easily be applied in the best aquaculture and fishery practices.","PeriodicalId":9116,"journal":{"name":"Bollettino della Societa italiana di biologia sperimentale","volume":"15 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85985387","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moreover, we also measured serum estradiol levels of endometriosis patients in the proliferation phase of the menstrual cycle using the enzyme-linked immunosorbent assay method. The mRNA expression of ERβ was significantly higher in the endometriosis group compared to control, and the result of t-test showed that were significantly different (P<0.05). Overexpression of ERβ in endometriosis was likely to have other significant important impacts in the pathology of endometriosis that allowed ERβ to stimulate prostaglandin production in endometriosis tissue and cells. Estradiol content did not correlate with the ERα expression, and it is weakly correlated with ERβ mRNA expression. Molecular docking analysis showed that ERα and ERβ have different binding interactions with synthetic antiestrogens, whereas the best inhibitor was Ral2 to ERα and Aco1 to ERβ.

Its immunosuppressive action is linked to the substantial action mechanism in the inhibition of the synthesis of nitrogenous bases purine carried out in T-lymphocyte. The level of such medication limit resides in side effects such as myelosuppression and the development of tumours. The occurrence of side effects is linked to the presence of genetic polymorphisms of Thiopurine methyltransferase (TPMT). To date, 40 allelic variants for TPMT have been detected. However, those responsible for the reduction of enzyme activity are three: *2, *3A, *3C. The presence of one of the three polymorphisms makes the enzyme susceptible to degradation at proteasome level, and exposes the patient to high levels of the active drug that increases the probability of an occurrence of its side effects. Therefore, the Food and Drug Administration imposed the execution of a genetic test of TPMT typing in order to determine if the drug therapy is appropriate to the metabolic characteristics of the patient. The study had the aim of identifying the prevalence of the three aforementioned polymorphisms related to TPMT in a sample population in Palermo, Italy, highlighting the differences related to the sex of the patient and highlighting the main phenotypes. The results showed prevalence in the population of the absence of polymorphism. Among the most frequent polymorphisms is the *3A (3%). A percentage of 1.5% was found for the polymorphism *3C.

Acute oral toxicity study was carried out based on Organization for Economic Cooperation and Development 423 guideline. The extract was orally administered in wistar rats at a single dose of 2000 mg/kg body weight and the animals were observed for mortality, behavioral changes and other abnormal signs. Qualitative analysis of phytochemical constituents was carried out using standard methods developed by Harborne, Trease and Evans. Castor oil-induced diarrhoea tests and gastro intestinal motility assay were evaluated in rats to determine the antidiarrhoeal activity of the extract. In the acute toxicity study, the extract did not induce death or any sign of toxicity in treated rats. The preliminary phytochemical screening of the extract revealed the presence of saponins, flavonoids, and triterpenoids. The oleaster extract at oral doses of 100, 200 and 400 mg/kg body weight showed a significant (P<0.05) antidiarrhoeal activity compared to the control group treated with castor oil induced diarrhoea, enteropooling and gastrointestinal motility assay, after charcoal meal administration.
