Published: April 2009

AbstractThe rarity of top predators has been identified as a contributing factor in the collapse of entire ecological systems. Elucidating the ecology, evolutionary potential and population response of species before a threatening process requires a combination of measures of phenotypic variation, demography and genetic diversity using an array of markers. Here we use such information to determine the population structure and its conservation implications for a keystone marsupial carnivore in Western Australia, the northern quoll Dasyurus hallucatus, ahead of the spread of the exotic and poisonous cane toad Chaunus marinus from the east. The western populations occur in two discrete geographic regions on the mainland, the Kimberley and Pilbara, separated by the arid Great Sandy Desert, and on several continental islands. Both mitochondrial DNA sequences and 11 nuclear microsatellite loci reveal clear differentiation of the Kimberley and Pilbara regions. Offshore islands with permanent sea‐channels from the mainland show reduced diversity and were genetically distinct indicating genetic isolation, whereas those separated from the mainland by very shallow channels were more similar to the adjacent mainland populations, suggesting on‐going gene flow. There was little indication that any population within the distribution of the species had experienced recent declines but there was marked variation in sexual dimorphism suggesting diversity in demographic performance. These populations in Western Australia differ from those remaining to the east in Queensland and the Northern Territory, in both genetic structure and demographic parameters and represent the last intact populations in Australia that have not experienced major declines concomitant with the spread of the cane toad. Consequently, the genetic and demographic flexibility recorded by this study provides guidance for the conservation and management of a major marsupial predator before and during its potential decline associated with an invasive, threatening prey species.

Abstract:  Background/Objectives:  Understanding the public’s perception of nevi and sunburn is crucial to melanoma prevention efforts.Methods:  We investigated the knowledge and perception of melanocytic nevi and sunburns in 77 children 6 to 10 years old (mean 8.2) in two elementary schools in Styria, Austria. The children were interviewed by specially trained psychologists about the number of their moles and how they felt having them. Additionally questions about sunburn history and sunburn perception were asked. The spontaneous answers of the children were recorded, there were no pregiven answers. Afterwards the children were examined by dermatologists clinically and with dermatoscopes.Results:  The 96% of the children could describe a nevus (the term “mole” was translated to “nevus”) and 91% did not feel bothered about theirs. Only 26% had noted the appearance of new nevi within the last year. The 67% of all children had at least one sunburn and remembered the clinical features. The 20% of the children knew that sunburns could provoke skin cancer. All children felt comfortable during the clinical and dermatoscopic examination.Conclusion:  Children aged from 6 to 10 years know exactly why they had suffered from sunburn, can describe the sunburn and how to avoid it. They do not feel bothered by their nevi and are alert to the appearance of new nevi.

OBJECTIVES: To determine whether the offspring of centenarians have personality characteristics that are distinct from the general population.DESIGN: Case‐control.SETTING: Nationwide U.S. sample.PARTICIPANTS: Unrelated offspring of centenarians (n=246, mean age 75) were compared with published norms.MEASUREMENTS: Using the NEO‐Five‐Factor Inventory (NEO‐FFI) questionnaire, measures of the personality traits neuroticism, extraversion, openness, agreeableness, and conscientiousness were obtained. T‐scores and percentiles were calculated according to sex and used to interpret the results.RESULTS: Male and female offspring of centenarians scored in the low range of published norms for neuroticism and in the high range for extraversion. The women also scored comparatively high in agreeableness. Otherwise, both sexes scored within normal range for conscientiousness and openness, and the men scored within normal range for agreeableness.CONCLUSION: Specific personality traits may be important to the relative successful aging demonstrated by the offspring of centenarians. Similarities across four of the five domains between male and female offspring is noteworthy and may relate to their successful aging. Measures of personality are an important phenotype to include in studies that assess genetic and environmental influences of longevity and successful aging.
Catheter Selection for Coronary Angiography and Intervention in Anomalous Right Coronary Arteries
Authors: SARKAR KUNAL , SHARMA SAMIN K. , KINI ANNAPOORNA S. 
Published: April 2009

Background: An anomalous origin of the right coronary artery (ARCA) from the left sinus of Valsalva (LSOV) has been reported in 6–27% of patients with coronary anomalies. The unusual location and course of this anomaly poses a technical challenge for the interventionalist. Appropriate guiding catheter selection is critical to ensure successful angiography and percutaneous intervention (PCI). We report our experience in 24 patients with an anomalous RCA originating from the LSOV.
Methods: Twenty‐four angiograms of ARCA‐LSOV were reviewed by two independent interventionalists with attention to the origin and take off of the RCA within the aortic root. The origin was adjudicated with a scheme based on anatomical landmarks as described—A: origin from the aorta above the sinotubular plane; B: origin just below the ostium of the left coronary artery (LCA); C: origin below the sinotubular plane between the midline and the LCA; D: origin along the midline.
Results: The distribution of various takeoffs of the RCA was as follows: For type A (N = 4) the FL3.0 and FCL3.0 catheters were successful in three and one cases, respectively. For type B (N = 5) the FCL3.0 or 3.5 was successful in four out of the five cases. For type C (N = 9) the VL catheter was successful in eight (VL3.5 = 5:VL 3.0 = 3) cases. The AL catheter was successful in five cases of type D (N = 6) RCAs (AL1 = 3:AL2 = 1:AL3 = 1).
Conclusions: The classification method and catheter selection provide a useful framework to successfully engage ARCA‐LSOV and may reduce contrast and radiation exposure.
Encapsulated cargo internalized by fusogenic liposomes partially overlaps the endoplasmic reticulum
Authors: Mustata Roxana C. , Grigorescu Alina , Petrescu Stefana M. 
Published: April 2009

AbstractFew endocytosed ligands, including bacterial toxins and simian virus 40 (SV40) have been shown to reach the endoplasmic reticulum (ER) in mammalian cells. Using calcein and fluorescently labelled lactoferrin encapsulated in fusogenic liposomes we found that the cargo uses a microtubule‐based pathway with ER delivery. Endocytic uptake of the lipid vesicles was cholesterol dependent in all cell lines tested, including the caveolin‐1‐deficient human hepatoma 7 cell line. The ligand was transported in non‐caveosome organelles requiring acidic pH for maturation, but able to escape the lysosomal route. These organelles were not recycling endosomes either, as shown by the lack of co‐localization with recycling transferrin. Co‐localization with the ER‐tracker, orange fluorescent protein with KDEL signal retention and cholera toxin in live microscopy revealed an ER distribution of the fluorescent ligand. Brefeldin A, which prevents Golgi‐dependent retrograde trafficking, does not disrupt the cargo delivery to the ER. This new endocytic pathway making use of acidic endosome‐like organelles is an alternative to the reported SV40 caveolae pathways. Exploiting a cellular route linking the cell surface to the ER, fusogenic liposomes may become efficient drug delivery vehicles for ER stress and diseases.

Published: April 2009

ABSTRACTLaurus nobilis is one of the most broadly used spices in Moroccan gastronomy. Its antimicrobial activity against both gram‐positive and gram‐negative bacterial species was demonstrated. Likewise, its toxicity was investigated on Swiss albinos' mice. Daily, mice were treated orally with 0.003 and 0.3 mg during 7 days. Plasmatic markers and enzymatic systems were assessed and histological alterations were evaluated. A significant increase in creatine phosphokinase level was observed. The microscopic evaluation showed that L. nobilis induces morphological perturbation in mice's liver. The results also showed an inhibitory effect of glyceraldehydes 3‐phosphate dehydrogenase and an important increase in the level of thiobarbituric acid reactive substances and succinate dehydrogenase and no change in catalase activities. The results showed that L. nobilis induces toxicity at 0.3 mg/g mouse and affects energy metabolism and oxidative stress.PRACTICAL APPLICATIONSThe aim of the present study is to determine the antimicrobial effect of Laurus nobilis on pathogens for potential application as herbal medicine in infusion or oral preparation. The effect of the spice extract was investigated on the metabolic markers, stress biomarkers and clinical parameters. This study was completed with histological coupes. To our knowledge, this is the first report to demonstrate the laurel effect on energy metabolism and oxidative stress.

ABSTRACT The aim of the present work was to study the influence of temperature on sensory and microbiological qualities, and on shelf life of butterhead lettuce leaves in passive modified atmosphere packages. Butterhead lettuce was washed and placed under ambient air in 30 × 40 cm polypropylene bags, and stored at 5, 10 and 15C. A first‐order equation was obtained for the development of the evaluated appearance sensory attributes as a function of storage time. For all the evaluated storage temperatures, microbiological shelf lives (14, 17 and 42 days at 5, 10 and 15C) were higher than estimated sensory shelf lives (8, 14 and 26 days at 5, 10 and 15C), showing that shelf life of lettuce in passive modified atmosphere packages was limited by sensory properties and not by microbial growth.PRACTICAL APPLICATIONSSensory shelf life of lettuce in passive modified atmosphere packages was estimated using consumer data, which are an improvement of a more arbitrary criteria presented in most studies. Moreover, if failure criteria used in other studies were applied, consumer rejection at the end of shelf life would be higher, suggesting that more conservative criteria are necessary to assure the product's quality at the end of its shelf life.

Published: April 2009

AbstractEighty‐four pollen samples were obtained for 80 taxa, of which, 13 species and one variety are from sect. Brachycalyx Sweet, 58 species and two varieties from sect. Tsutsusi Sweet, and six species from subgen. Pentanthera (G. Don) Pojarkova, respectively. Pollen morphology of all samples was observed using LM and SEM. Pollen grains are revealed to be spheroidal and tetrahedral with tricolporate apertures. Pollen sizes of subgen. Tsutsusi (Sweet) Pojarkova range from 37.67 μm to 61.06 μm, and the exine sculptures are more or less compactly granulated. Pollen sizes are significantly different between sect. Brachycalyx and sect. Tsutsusi of subgen. Tsutsusi. Rhododendron tashiroi Maxim. of sect. Tsusiopsis Sleumer shows a close affinity to sect. Brachycalyx. Pollen size and exine are consistent with general morphology in differentiating species in sect. Tsutsusi. Rhododendron huadingense B. Y. Ding & Y. Y. Fang, once placed as a member of sect. Brachycalyx, should be considered as a species in subgen. Pentanthera.

Authors: LIU Wei , ZHU Xiang‐Yun 
Published: April 2009

AbstractAfter examining a large number of type and authoritative specimens of Schizophragma Siebold & Zucc., S. elliptifolium C. F. Wei and S. integrifolium var. glaucescens Rehder were reduced to synonyms of S. hypoglaucum Rehder and S. integrifolium f. cordatum S. Y. Wang was reduced to synonym of S. corylifolium Chun. Schizophragma crassum var. ellipticum J. Anthony was treated as the correct name of S. crassum var. hsitaoanum (Chun) C. F. Wei. The name S. integrifolium var. minus Rehder is reinstated. The taxonomic treatment is supported by leaf epidermal characters.

First report of Protokeelia spinifera and Rhopalodia iriomotensis from China, with comments on their systematic positions
Authors: LI Yang , GAO Ya‐Hui , LU Song‐Hui 
Published: April 2009

Abstract Protokeelia is described as a new and rare pennate diatom genus in China. Its valve includes two parts: ventral valve and dorsal valve. The ventral valve is more or less convex or concave. The raphe runs in a distinct elevated and thickened siliceous ridge. In the internal valve, beneath the raphe are fibulae or fibulae clusters which connect the ventral and dorsal valves. One species, P. spinifera Round & Basson, is observed in the water samples from a mangrove forest in Sai Kung, Hong Kong, China. Its main morphological features are described in this paper along with electron microscope (EM) photos. Morphological comparisons are also made among several allied species. In addition, a newly recorded species for China, Rhopalodia iriomotensis Kobayasi, Nagumo & Tanaka, is discussed here. Because several key features observed in this species resemble those of some Protokeelia species, we suggest that it may actually represent a Protokeelia species.

ABSTRACTCellular and humoral immune responses of healed cutaneous leishmaniasis and Mediterranean visceral leishmaniasis patients were evaluated against results forLeishmania majorvirulence proteinsL. majorprotein disulfide isomerase (LmPDI) and mitogen-activated protein kinase kinase (MAPKK). Only MAPKK induces significant peripheral blood mononuclear cell proliferation with gamma interferon production as well as antibody responses. Thus, MAPKK may be of interest inLeishmaniavaccination and serodiagnosis.
The mechanisms of atrial fibrillation in hyperthyroidism
Authors: Bielecka-Dabrowa Agata , Mikhailidis Dimitri P , Rysz Jacek , Banach Maciej 
Published: April 2009

Abstract
Atrial fibrillation (AF) is a complex condition with several possible contributing factors. The rapid and irregular heartbeat produced by AF increases the risk of blood clot formation inside the heart. These clots may eventually become dislodged, causing embolism, stroke and other disorders. AF occurs in up to 15% of patients with hyperthyroidism compared to 4% of people in the general population and is more common in men and in patients with triiodothyronine (T3) toxicosis. The incidence of AF increases with advancing age. Also, subclinical hyperthyroidism is a risk factor associated with a 3-fold increase in development of AF. Thyrotoxicosis exerts marked influences on electrical impulse generation (chronotropic effect) and conduction (dromotropic effect). Several potential mechanisms could be invoked for the effect of thyroid hormones on AF risk, including elevation of left atrial pressure secondary to increased left ventricular mass and impaired ventricular relaxation, ischemia resulting from increased resting heart rate, and increased atrial eopic activity. Reentry has been postulated as one of the main mechanisms leading to AF. AF is more likely if effective refractory periods are short and conduction is slow. Hyperthyroidism is associated with shortening of action potential duration which may also contribute to AF.

Published: April 2024

AbstractFiber‐based artificial muscles are promising for smart textiles capable of sensing, interacting, and adapting to environmental stimuli. However, the application of current artificial muscle‐based textiles in wearable and engineering fields has largely remained a constraint due to the limited deformation, restrictive stimulation, and uncomfortable. Here, dual‐responsive yarn muscles with high contractile actuation force are fabricated by incorporating a very small fraction (<1 wt.%) of Ti3C2Tx MXene/cellulose nanofibers (CNF) composites into self‐plied and twisted wool yarns. They can lift and lower a load exceeding 3400 times their own weight when stimulated by moisture and photothermal. Furthermore, the yarn muscles are coiled homochirally or heterochirally to produce spring‐like muscles, which generated over 550% elongation or 83% contraction under the photothermal stimulation. The actuation mechanism, involving photothermal/moisture‐mechanical energy conversion, is clarified by a combination of experiments and finite element simulations. Specifically, MXene/CNF composites serve as both photothermal and hygroscopic agents to accelerate water evaporation under near‐infrared (NIR) light and moisture absorption from ambient air. Due to their low‐cost facile fabrication, large scalable dimensions, and robust strength coupled with dual responsiveness, these soft actuators are attractive for intelligent textiles and devices such as self‐adaptive textiles, soft robotics, and wearable information encryption.
