AbstractPlagioptychids are a conspicuous, although minor, component in uppermost Cretaceous rudist-bearing outcrops of the Caribbean Province, where other rudist families are more abundant and diverse. In the Chiapas Central Depression, the plagioptychid rudist fauna includes the following taxa: Plagioptychus antillarum (Douvillé) and Mitrocaprina sp. from the middle Campanian Suchiapa Formation, Plagioptychus muellerriedi Alencáster from the early Maastrichtian Ocozocoautla Formation, and Plagioptychus fragilis Chubb and Mitrocaprina tschoppi (Palmer) from the late Maastrichtian Angostura Formation. These five species are described in detail and some probable synonymies are discussed. Analysis of the literature on American plagioptychids reveals that the characters of too many taxa are still insufficiently known to attempt any thorough phylogenetic analysis. Other lines of evidence also seem to indicate that American Plagioptychidae diversity is probably higher than recognized today, which might result in a more significant difference to Plagioptychidae of the Mediterranean Tethys.

AbstractHippuritids, particularly those with multiple-folds, are one of the most characteristic components in uppermost Cretaceous rudist-bearing strata of the Caribbean Province. The hippuritid rudist fauna of the Chiapas Central Depression includes the following taxa:Vaccinites vermuntiMac Gillavry, 1937 andBarrettiacf.B. ruseaeChubb, 1967 from the early Campanian Suchiapa Formation;B. moniliferaWoodward, 1862,B. gigasChubb, 1955, andParastroma trechmanniChubb, 1967 from the mid Campanian Suchiapa Formation; andPraebarrettia sparcilirata(Whitfield, 1897) from the early Maastrichtian Ocozocoautla Formation. These six species are described herein in detail. New observations on the outer shell layer structure of the right valve and the pore-canal system of the left valve led to amending the diagnoses of the g|eneraBarrettiaWoodward, 1862,ParastromaDouvillé, 1926, andPraebarrettiaTrechmann, 1924. Also, the revision of Chiapas’ and other American species of multiple-fold hippuritids led to proposed changes in their generic adscription.

Abstract The systematics and taxonomy of the broadly distributed bats of the genus Cynomops has changed considerably in the last few years. Among the major changes, Cynomops abrasus was split into two species of large-bodied forms (Cynomops mastivus and C. abrasus) distributed east of the Andes. However, large Colombian specimens identified as C. abrasus from the western side of the Andes had yet to be included in any revisionary work. Phylogenetic analysis performed in this study, using mtDNA sequences (Cytochrome-b), revealed that these Colombian individuals are more closely related to Cynomops greenhalli. Morphological and molecular data allowed us to recognize populations from western Colombia, western Ecuador and northwestern Peru, as members of a new species of Cynomops. Characters that allow for its differentiation from C. greenhalli include a larger forearm, paler but more uniform ventral pelage, more globular braincase, and well-developed zygomatic processes of the maxilla (almost reaching the postorbital constriction). This study serves as another example of the importance of including multiple lines of evidence in the recognition of a new species. Given its rarity and the advanced transformation of its habitat, this new species is particularly important from a conservation perspective.

AbstractThe qualitative and quantitative parameters of temporal distribution ofCucullanus tripapillatusandCucullanus chrysophrydesin the intestine ofOrthopristis ruberin the Caribbean Sea on the north of Margarita Island, Venezuela were analysed. A total of 540 fish were collected at random from the catch of commercial trawlers during 1982–83 and 1992–93. Both species ofCucullanuswere found throughout the year; prevalence and mean intensity ofC. tripapillatuswere higher than that ofC. chrysophrydes. A significant difference was found in infection between the two years of sampling. Female worms were more abundant than male in both years. Both species exhibited pronounced prevalence and maturity in September and March of each year, indicating seasonality. The patterns of occurrence of the two species ofCucullanusinO. ruberdid not change in the 10-year interval but the host size and number of parasites declined, which may be due to over-exploitation of definitive fish hosts.

This book provides an accessible study of how peoples bordering the Mediterranean, North Sea, English Channel and eastern Atlantic related to the sea in all its aspects. This book surveys how the peoples bordering the Mediterranean, North Sea, English Channel and eastern Atlantic related to the sea in all its aspects between approximately 1000-1500 A.D.How was the sea represented in poems and other writings? What kinds of boats were used and how were they built? How easy was it to navigate on short or long passages? Was seaborne trade crucial to the economy of this area? Did naval warfare loom large in the minds of medieval rulers? What can be said more generally about the lives of those who went to sea or who lived by its shores? These are the major questions which are addressed in this book, which is based on extensive research in both maritime archives and also in secondary literature. It concludes by pointing out how the relatively enclosed maritime world of Western Europe was radically changed by the voyages of the late fifteenth century across the Atlantic to the Caribbean and round Africa to India.

AbstractA thorough chemical, molecular and morphological study has been carried out on a problematic group in the genus Lepraria characterized by lobed, granular thalli with a raised rim and a preference for mosses, rocks and mineral soils in exposed, xeric habitats. The material examined was collected in seven countries of the Mediterranean-Macaronesian region, from chalk, carbonate rocks and derived soils (A-thalli), and from siliceous rocks and derived soils (B-thalli). The results of a phylogenetic analysis based on 93 ITS sequences (29 of which newly obtained) support the identification and the segregation of two taxa at species level, provisionally identified as Lepraria isidiata s. lat., (most of the A-thalli), and L. santosii s. lat. (B-thalli plus the remaining A-thalli), as the observed genetic variability is quite high. Three chemotypes were detected in L. isidiata s. lat., and seven in L. santosii s. lat. The two taxa are morphologically well characterized: in L. isidiata s. lat. the thallus is thicker and the propagules larger than in L. santosii s. lat. The first stages of thallus development from single propagules are described in both species. Some critical remarks are made about the increasing use of the species rank for taxa of Lepraria, which are morphologically and genetically scarcely characterized.

Background: Nutritional support is very important in the treatment of Paediatric Inflammatory Bowel Disease (IBD). The role of the Mediterranean Diet (MD) has been understudied in children with IBD. The aims of this study were to assess the dietary intakes of IBD children in comparison with healthy controls (HCs), their adherence to MD; and the relationship between inflammation and dietary behaviors. Methods: Paediatric IBD patients in clinical remission and HCs were enrolled. The nutritional status and adherence to the Mediterranean Diet was evaluated through a 3-day food diary and the Mediterranean Diet Quality Index for Children and Adolescents (KIDMED). Results: The analysis of food diaries showed a significantly higher kilocalorie intake in IBD patients compared to HCs (p = 0.012), an increase in carbohydrates (p = 0.015) and in protein intake (p = 0.024). Both IBD and HCs have an intermediate adherence to MD. The comparison between Crohn’s disease (CD) and Ulcerative colitis (UC) patients showed significant difference in protein intake in CD patients (p = 0.047), as well as for vitamin D (p = 0.044) and iron intake (p = 0.023). Interestingly; in IBD patients we found a significant association between adherence to MD and a low level of fecal calprotectin (p = 0.027). Conclusion: Children with IBD in remission have a sub-optimal food intake compared to HCs. MD seems to correlate to decreased intestinal inflammation.

AbstractIntroductionThe determination of level of adherence to the Mediterranean diet (MD) in young adults has been investigated in countries situated near the Mediterranean region generally. The main purpose of this study were to determine differences in body composition by gender and level of adherence to the MD and to determine the relationship between body composition and level of adherence to the MD in Nutrition and Dietetics students at Near East University in Cyprus.Materials and MethodsThe study was conducted on 126 Nutrition and Dietetics students, aged 18 to 32 years. MDS was calculated, and then classified into three groups: good (36–55 points), moderate (21–35 points), and poor (0–20 points). Body composition was assessed using bioelectrical impedance (BIA). Anthropometrical measurements; height (H), body weight (BW), waist circumference (WC) and hip circumference (HC) were assessed according to standardized procedures and physical activity (PA) was assessed by using International Physical Activity Questionnaire (IPAQ-short form). The study protocol was approved by the Ethics Committee at Near East University.ResultsAccording to study results 31.0% of students were found out to low adherence, while 69.0% of students had moderate adherence to the MD. There is no student had high adherence to the MD. There was no significant difference (p = 0.877) between the male and female students in terms of adherence to Mediterranean diet. The findings indicate that the eating habits of the Nutrition and Dietetics students, even those studying nutrition, are in need of improvement. The results show that 78.6% of students were normal and 21.4% of students were overweight and obese. Male students’ BW (p = 0.000), WC (p = 0.000) and HC (p = 0.015) were higher than females’, while female students’ fat mass (FM) (p = 0.000) was higher than males’. However, there is no significant difference between BW (p = 0.724), FM (p = 0.896), BMI (p = 0.691), WC (p = 0.632) and HC (p = 0.982) neither low adherence nor moderate adherence to the MD. Most of students minimal active according to IPAQ scores (41.2%) and there is no significant difference IPAQ score and adherence to the MD (p = 0.923).DiscussionOne of the healthiest diets worldwide is the traditional MD. Several studies have shown, that higher adherence to the MD is inversely related with BMI, waist circumference (WC) and waist-to-height ratio (WHR). Little is known of how adherence to the MD is related to body composition, especially in university students. Further large-scale studies are required to clarify the relationship between adherence to the MD and body composition

AbstractObjectiveTo assess adherence to the Mediterranean diet and nutrient intakes in a population of Sicily, southern Italy and to evaluate possible determinants, particularly socio-cultural and lifestyle factors.DesignCross-sectional.SettingUrban and rural areas of eastern Sicily.SubjectsBetween May 2009 and December 2010, 3090 adults were randomly recruited through the collaboration of fourteen general practitioners. Adherence to the Mediterranean diet was measured by the MedDietScore. Nutrient intakes were assessed through the 24 h recall of the previous day's dietary intake.ResultsRural participants were barely more adherent to the Mediterranean diet than their urban counterparts (mean scores were 27·8 and 27·2, respectively, P = 0·037). The MedDietScore was correlated with intakes of MUFA, fibre and vitamin C, as well as with consumption of non-refined cereals, vegetables, fruit, meat, dairy products, alcohol and nuts. Regression analysis revealed that older and more educated people were more likely to be in the highest tertile of MedDietScore (OR = 1.90; 95 % CI 1·39, 2·59 and OR = 1·29; 95 % CI 1·05, 1·58, respectively). A significant difference in quantity (moderate) and quality (red wine and beer) of alcohol was found according to adherence to the Mediterranean diet. Finally, more active participants were 1·5 times more likely to form part of the high-adherence group.ConclusionsA slow but concrete moving away from traditional patterns has been observed in younger people and low educated people. Public health interventions should focus on these target populations in order to improve the quality of their diet.

Background/Aims: Several lines of evidence have been reported that oxidative stress plays an important role in the pathogenesis of Preeclampsia (PE). Therefore, this research is aimed to investigate whether polymorphisms of CYBA are related to susceptibility to PE in Chinese Han women. Methods: We studied the genetic frequency of the rs9932581 and 1049255 polymorphisms in CYBA in 1029 PE patients and 1400 controls of later pregnant women by the TaqMan allelic discrimination real-time PCR and a case-control model. Results: Our research indicated that no significant differences were found for the genotypic or allelic frequencies at the two polymorphic sites in CYBA between PE patients and controls. To further study the relationship between the polymorphic sites and PE, we also found that there is no significant difference in the genetic distributions identified between the mild or severe PE and early or the late-onset PE and controls. Conclusion: The study demonstrated that the genetic variants of rs9932581 and rs1049255 in CYBA might not be associated with PE. However, investigations of genetic variability that influence on the disease outcome are needed in other large prospective populations or regions, so the complicated interconnection of genetic and environmental elements can be emulated for better understanding.
