Biochemical profiles of hydatid cyst fluids of Echinococcus granulosus of human and animal origin in Iran

A comparative study on the biochemical parameters in hydatid cyst fluids of sheep, goat, camel, cattle and human cystic forms of Echinococcus granulosus has been made in Iran. Quantitative variations in the levels of glucose, calcium and creatinine in the cystic fluids of camels were found with hydatid fluids of sheep, goat, cattle and humans. These differences were statistically significant (P<0.05). Similarities in the biochemical composition in hydatid cyst fluids of sheep, goat, cattle and humans suggest the existence of sheep strains of E. granulosus and differences in the biochemical composition in hydatid cyst fluids of camel with other domestic animals and humans suggest the existence of camel strains of E. granulosus in Iran.
On the Front Line: frontal zones as priority at-sea conservation areas for mobile marine vertebrates

productivity are key biophysical characteristics of ecologically signiﬁcant frontal zones in contrasting oceanographic regions. Persistent frontal zones are potential priority conservation areas for multiple marine vertebrate taxa and are easily identiﬁable through front mapping via EO remote sensing. These insights are useful for marine spatial planning and marine biodiversity conservation, both within Exclusive Economic Zones and in the open oceans.
Preoperative Nutritional Status and Its Consequences on Abdominal Surgery in Wolaita Zone, Southern Ethiopia: An Institution-Based Observational Study

This study aimed to determine the prevalence of malnutrition and its association with wound healing and length of hospitalization among patients undergoing abdominal surgery admitted to hospitals in the Wolaita zone in southern Ethiopia. Methods. An institution-based prospective observational study was conducted in three hospitals in the Wolaita zone from August to October 2016. All eligible individuals aged between 19 and 55 years were recruited in this study. Anthropometric and biochemical analyses, such as serum albumin (Alb) and total lymphocyte count (TLC), were taken for nutritional assessment during the preoperative period. Quantitative variables were compared using Student's t test. Cox's regression was employed to determine which variables were possible risk factors for poor wound healing. Results. A total of 105 patients aged 19 to 55 with a mean age (±SD) of 34 ± 9.6 years were included, and the prevalence of preoperative malnutrition was 27.6%, 87%, according to BMI and nutritional risk index, respectively. Poor wound healing was significantly associated with underweight patients (BMI < 18.5 kg/m2) (AHR: 6.5 : 95%CI: 3.312.9), postoperative weight loss (AHR: 4.9; 95%CI: 2.8–8.5), and nutritional risk index (NRI) less than 97.5 (AHR 1.8; 95% CI: 1.09–3.1). Conclusion. The prevalence of malnutrition is high in our study setup; this is associated with an increased risk of adverse postoperative outcomes. Therefore, our results emphasize the need of routine preoperative nutritional assessment, optimizing nutritional status of patients and postoperative nutritional support.
Effectiveness of a brief lifestyle intervention targeting mental health staff: analysis of physical fitness and activity in the Keeping Our Staff in Mind study

Background People with mental illness die on average 15 years less than the general population, primarily to cardiometabolic disease. Lifestyle interventions are effective in reducing cardiometabolic risk but are not routinely provided to mental health consumers. Lifestyle interventions targeting mental health staff may be beneficial in changing culture surrounding physical health and subsequently improving consumer outcomes. This study examines exercise and fitness outcomes of a targeted lifestyle intervention directed at Australian mental health staff. Methods A pragmatic single-arm intervention study was conducted within an Australian public mental health service. Mental health staff were provided a five-session individualised lifestyle intervention (incorporating exercise and nutritional counselling) over 5 weeks. Two waves of the programme were delivered between 2015 and 2016. This paper examines the exercise and fitness outcomes of the second wave of the study. Participants were assessed at baseline and at a 16-week follow-up. The primary exercise outcome was a measurement of cardiorespiratory fitness. Secondary outcomes included self-reported physical activity and a measurement of handgrip strength. Results A total of 106 staff participated in this component of the study. Cardiorespiratory fitness increased significantly from baseline to follow-up (p<0.001). Significant improvements to physical activity occurred with decreases in sedentary time (p<0.0005) and increases in moderate-to-vigorous physical activity (p<0.005). Conclusion Lifestyle interventions incorporating exercise counselling may improve the physical health of mental health staff. Such strategies may be effective in improving culture surrounding physical health and/or increasing the effectiveness of lifestyle interventions targeting mental health consumers.
Separating environmental and geographical determinants of phylogenetic community structure in Amazonian palms (Arecaceae)

Phylogenetic information can provide important insight into the assembly of hyper-diverse tropical rainforest communities. The hierarchical nature and scale dependency of phylogenetic community structure can be used to disentangle complex networks of assembly mechanisms. Here, we outline how particular assembly mechanisms can be identified by analysing phylogenetic community structure on different scales related to space and environment. We present a case study on a large set of species-rich palm communities from the western Amazon basin. We aimed to elucidate the assembly of these communities by separating the roles of broad-scale biogeographic processes, habitat filtering and intra-habitat processes. Overall, we found phylogenetic clustering, which could be caused by a variety of different processes. When we reduced the species pool according to regions, habitats or soil sand content, we found that the structure was consistent with a combination of regional biogeographic differentiation, habitat filtering and within-habitat processes. The habitat filtering effect was strongest, although it varied in strength among communities in different habitats. Some phylogenetic structure could not be accounted for by biogeography or habitat, suggesting that intra-habitat processes such as micro-environmental filtering or biotic interactions also play a role. © 2012 The Linnean Society of London, Botanical Journal of the Linnean Society, 2012, ••, ••–••.
Miscanthus × giganteus Response to Preemergence and Postemergence Herbicides

Abstract Miscanthus is a perennial rhizomatous C4 grass being evaluated in the United States as a potential bioenergy feedstock. Weed control during the first two growing seasons is essential for successful establishment. No herbicides are currently labeled for use in Miscanthus grown for biomass, but herbicides used on field corn might be safe to Miscanthus. Greenhouse experiments were conducted in 2007 and 2008 to evaluate the response of Miscanthus to numerous preemergence (PRE) and postemergence (POST) herbicides. Herbicides with activity only on broadleaf species, whether PRE or POST, did not exhibit injury or reduce Miscanthus biomass. Several herbicides, particularly those with significant activity on grass species, exhibited injury ranging from 6 to 71% (scale of 0 to 100) and/or reduced Miscanthus dry mass by 33 to 78%, especially at the highest rates applied. Field experiments were conducted in 2008 and 2009 with a selection of the herbicides used in the greenhouse experiments to evaluate the response of Miscanthus to herbicides applied PRE, POST and PRE followed by POST. Results from the field experiments generally confirmed those from the greenhouse experiments. PRE herbicides and herbicides with broadleaf-specific activity generally did not produce significant injury or reduce aboveground biomass while herbicides with grass activity tended to cause injury ranging from 22 to 25% and/or reduce biomass by 69 to 78%. With some exceptions, results support prior suppositions that herbicides used in corn are safe to use on Miscanthus and may provide potential herbicide options that growers can use when establishing Miscanthus. Nomenclature: Miscanthus, Miscanthus × giganteus Greef and Deuter ex Hodkinson and Renvoize; corn, Zea mays L.
Variation in the sublittoral macrozoobenthos of the Baltic Sea along environmental gradients: A functional-group approach

The enclosed Baltic Sea, one of the world's largest brackish water basins, resembles a large estuary with steep horizontal and vertical environmental gradients. Thus, salinities range from 25 to 30 ppt in the Danish Sound area in the south to 1-3 ppt in the inner reaches of the Gulfs of Bothnia and Finland, and a persistent pycnocline in the Baltic basin causes stagnation of bottom waters for long periods, with periodic hypoxia/anoxia as a consequence, over an area covering up to 100 000 km 2 . Further, climatic variation from boreal to subarctic causes additional stress on the ecosystem, In recent decades, eutrophication and pollution have also significantly affected the biota of the Baltic Sea. The soft bottom infauna is poor in terms of species composition, and functional complexity is considered to be low. This paper examines the estuarine soft bottom infauna of the Baltic Sea along some principal environmental gradients using a functional-group perspective. We have used the functional-group concept (primarily feeding type, mobility and microhabitat), designed for polychaetes by Fauchald and Jumars (1979), to analyze and illustrate if and how the environmental gradients are reflected in the zoobenthos. A total of 25 functional groups were identified, forming clines from complex functional communities in the south and west, towards functionally poor assemblages in the north and east. The shift in functional groups indicates a loss of carnivores, tentaculate sessile organisms, and burrowers from areas beyond the Baltic and its marine approaches towards the inner bays. On the other hand, suspension feeders and surface deposit feeders increase in importance. In the northernmost areas of the Baltic only 1-3 functional groups are found, compared to 8-20 in the south.
Risk Stratification in Advanced Biliary Tract Cancer: Validation of the A.L.A.N. Score

Background In addition to the clinical parameters, immune-inflammatory markers have emerged as prognostic factors in patients with advanced biliary tract cancer (ABC). The recently proposed A.L. A.N. score combines both in an easily applicable manner. The aim of this study was to perform the first external evaluation of this score. Methods All patients from our clinical registry unit who had unresectable ABC underwent first-line chemotherapy from 2006 to 2018 and met the inclusion criteria of the original study were included (n = 74). The A.L. A.N. score comprises the following parameters: actual neutrophil count, lymphocyte-to-monocyte ratio, albumin, and neutrophil-to-lymphocyte ratio (A.L.A.N.). Univariate and multivariate hazard regression analyses were performed to evaluate the score's parameters regarding overall survival (OS). The concordance index (C-index) and integrated Brier score (IBS) were calculated to evaluate the score's predictive performance. Results Low, intermediate, and high A.L. A.N. scores corresponded to median OS of 21.9, 11.4, and 4.3 months, respectively, resulting in a significant risk stratification (log-rank p=0.017). In multivariate analysis, a high-risk A.L. A.N. score remained an independent predictor of poor survival (p=0.016). Neutrophil-to-lymphocyte ratio was not a significant factor for poor OS in the analyses in the cohort. The score's ability to predict individual patient survival was only moderate with a C-index of 0.63. Conclusions The A.L. A.N. score can be used to identify risk groups with a poor prognosis prior to the start of chemotherapy. However, the ability of the score to predict individual patient outcome was only moderate; thus, it may only serve as a minor component in the complex interdisciplinary discussion.
Influence of copepod size and behaviour on vulnerability to predation by the scyphomedusa Aurelia aurita

The influence of copepod prey size and behaviour upon Aurelia aurita medusae predation rates was investigated. There was no significant difference in predation rates across a 4-fold (250 to 987 mm) prey size range (heat-killed developmental stages of Acartia tonsa). Any behavioural differences (e.g. swimming speed, escape response) across live A. tonsa developmental stages had no significant effect upon their susceptibility to predation. In addition, Aurelia aurita ingestion rates were similar upon adult males and females of a copepod that exhibit similar swimming speeds (A. tonsa), as well as upon both adult sexes of a copepod with contrasting swimming behaviour (Oithona similis). An encounter model indicated that the size and speed of Aurelia aurita overwhelmed the differences in size and swimming speeds of these prey by largely determining encounter rates. However, overall, heat-killing prey lead to significantly higher predation rates than those upon live prey. This may be attributed to the escape response of live prey, which is not included in the encounter model. The capture efficiency of Aurelia aurita was low (,9%), but high ingestion rates may be achieved through the large encounter rates of this cruising predator.
Canine Leishmaniosis Control through the Promotion of Preventive Measures Appropriately Adopted by Citizens

Canine leishmaniosis (CanL) is a disease caused by the protist Leishmania infantum and transmitted to dogs by sand fly (Diptera: Phlebotominae) bites. In 2005, a new autochthonous focus of CanL was recognised in the southern part of Euganei hills (northeastern Italy). In subsequent years, this outbreak was monitored, testing dogs and evaluating sand fly population. Moreover, dog owners were sensitized on the adoption of preventive measures, thanks to the collaboration of local administration, health authorities, and private veterinarians. This study includes serological tests on dogs, questionnaires submitted to dog owners regarding the use of preventive measures on their animals, and the evaluation of sand fly abundance. Data collected were statistically compared with those of previous years. The canine seroprevalence was significantly lower than that recorded at the beginning of the outbreak, despite the fact that sand fly abundance did not significantly decrease. In addition, most of the dog owners declared using regularly the topical insecticides on their dogs during the sand fly season. This experience demonstrated that a collaborative approach among scientific researchers, local authorities, and private veterinarians can achieve excellent results in the management of a leishmaniosis outbreak.
The relationships of mammals

A cladistic analysis generates alternative hypotheses regarding both the origin and the interrelationships of mammals to those most widely accepted at the present time. It is proposed that the tritylodontids are more closely related to mammals than is Probainognathus; that the non-therian mammals do not constitute a monophyletic group; and that the monotremes are related to the modern therians, the ear ossicles among other characters having evolved only once. The multituberculates may be related to the monotremes. It is argued that the current views are variously based on an overemphasis of superficial dental similarities, misinterpretation of the structure of the mammalianbraincaseand too readyacceptance of parallel evolution amongstthe groups concerned. The hypotheses proposed here are apparently much more parsimonious.
A Project for Monitoring Trends in Burn Severity

Elected officials and leaders of environmental agencies need information about the effects of large wildfires in order to set policy and make management decisions. Recently, the Wildland Fire Leadership Council (WFLC), which implements and coordinates the National Fire Plan (NFP) and Federal Wildland Fire Management Policies (National Fire Plan 2004), adopted a strategy to monitor the effectiveness of the National Fire Plan and the Healthy Forests Restoration Act (HFRA). One component of this strategy is to assess the environmental impacts of large wildland fires and identify the trends of burn severity on all lands across the United States.To that end, WFLC has sponsored a six-year project, Monitoring Trends in Burn Severity (MTBS), which requires the U.S. Department of Agriculture Forest Service (USDA-FS) and the U.S. Geological Survey (USGS) to map and assess the burn severity for all large current and historical fires. Using Landsat data and the differenced Normalized Burn Ratio (dNBR) algorithm, the USGS Center for Earth Resources Observation and Science (EROS) and USDA-FS Remote Sensing Applications Center will map burn severity of all fires since 1984 greater than 202 ha (500 ac) in the east, and 404 ha (1,000 ac) in the west. The number of historical fires from this period combined with current fires occurring during the course of the project will exceed 9,000.The MTBS project will generate burn severity data, maps, and reports, which will be available for use at local, state, and national levels to evaluate trends in burn severity and help develop and assess the effectiveness of land management decisions. Additionally, the information developed will provide a baseline from which to monitor the recovery and health of fire-affected landscapes over time. Spatial and tabular data quantifying burn severity will augment existing information used to estimate risk associated with a range of current and future resource threats. The annual report of 2004 fires has been completed. All data and results will be distributed to the public on a Web site.
Invention by evolution: functional analysis in paleobiology

Abstract Functional analysis of fossils is and should remain a key component of paleobiological research. Despite recently expressed doubts, conceptual and methodological developments over the past 25 years indicate that robust and testable claims about function can be produced. Functional statements can be made in at least three different hierarchical contexts, corresponding to the degree of structural information available, the position in the phylogenetic hierarchy, and the degree of anatomical specificity. The paradigm approach, which dominated thinking about function in the 1960s and 1970s, has been supplanted with a methodology based on biomechanics. Paleobiomechanics does not assume optimality in organismal design, but determines whether structures were capable of carrying out a given function. The paradigm approach can best be viewed as a way of generating, rather than testing, functional hypotheses. Hypotheses about function can also be developed and supported by well-corroborated phylogenetic arguments. Additional functional evidence can be derived from studies of trace fossils and of taphonomy. New computer techniques, including “Artificial Life” studies, have the potential for producing far more detailed ideas about function and mode of life than have been previously possible. Functional analysis remains the basis for studies of the history of adaptation. It is also an essential component of many paleoecological and paleoenvironmental studies.
Cerebral Blood Flow and Its Connectivity Deficits in Mild Traumatic Brain Injury at the Acute Stage

Objective The influence of cognitive impairment after mild traumatic brain injury (mTBI) on cerebral vascular perfusion has been widely concerned, yet the resting-state cerebral blood flow (CBF) connectivity alterations based on arterial spin labeling (ASL) in mild traumatic brain injury (mTBI) remain unclear. This study investigated region CBF and CBF connectivity features in acute mTBI patients, as well as the associations between CBF changes and cognitive impairment. Materials and Methods Forty-five acute mTBI patients and 42 health controls underwent pseudocontinuous arterial spin labeling (pCASL) perfusion magnetic resonance imaging (MRI). The alterations in regional CBF and relationship between the CBF changes and cognitive impairment were detected. The ASL-CBF connectivity of the brain regions with regional CBF significant differences was also compared between two groups. Neuropsychological tests covered seven cognitive domains. Associations between the CBF changes and cognitive impairment were further investigated. Results Compared with the healthy controls, the acute mTBI patients exhibited increased CBF in the bilateral inferior temporal gyrus (ITG) and decreased CBF in the right middle frontal gyrus (MFG), the bilateral superior frontal gyrus (SFG), and the right cerebellum posterior lobe (CPL). In the mTBI patients, significant correlations were identified between the CBF changes and cognitive impairment. Importantly, the acute mTBI patients exhibited CBF disconnections between the right CPL and right fusiform gyrus (FG) as well as bilateral ITG, between the left SFG and left middle occipital gyrus (MOG), and between the right SFG and right FG as well as right parahippocampal gyrus. Conclusion Our results suggest that acute mTBI patients exhibit both regional CBF abnormalities and CBF connectivity deficits, which may underlie the cognitive impairment of the acute mTBI patients.
DIET, FOOD PREFERENCES, AND DIGESTIVE EFFICIENCY OF THE GRAYISH SALTATOR, A PARTLY FOLIVOROUS PASSERINE

Abstract We studied the diet of the Grayish Saltator (Saltator coerulescens) during the rainy and dry seasons in the Venezuelan llanos and examined its food preferences, digesta retention time, rate of food intake, and digestive efficiency, in captivity. Grayish Saltators fed almost exclusively on plant tissues throughout the year. Fruits and leaves were the most commonly consumed items, comprising 36% and 28% of the diet, respectively, averaged over the entire year. In pairwise choice trials, saltators preferred fruits over leaves and flowers, and wild over cultivated leaves. In the laboratory, saltators displayed food-processing traits typical of frugivorous passerines. When feeding on a fruit (banana mash) diet, they had a fast rate of food passage (digesta mean retention time = 54 ± 26 min) and a relatively low digestive efficiency (average metabolizable energy coefficient = 0.59 ± 0.11), which was compensated for by high rates of food intake (1.4 times body mass). Mean retention time of a leaf-supplemented diet was slightly shorter (average = 45 ± 17 min). Birds maintained or increased their body masses under laboratory conditions when fed on a fruit diet but did not when fed exclusively with leaves. Saltators spent very little time foraging, and the amount of time varied seasonally (5% and 17% of the time in the rainy and dry seasons, respectively). Most of their time (ca. 50%) was dedicated to resting. The morphology of the digestive tract of this species is similar to other frugivorous birds, but the inner edge of the maxilla is serrated. We found no evidence of cellulolytic activity in the Grayish Saltator's gut. Together, all of these characteristics indicate that Grayish Saltators are partial folivores that rely on a “skimming” strategy of food consumption.
