Habitat quantity of Red-cockaded Woodpecker Picoides borealis (Aves: Piciformes: Picidae) in its former historic landscape near the Big Thicket National Preserve, Texas, USA
Authors: Thapa Vivek , Acevedo Miguel F. 
Published: January 2016

<p>We quantified pine-forested habitat suitable for Red-cockaded Woodpecker <em>Picoides borealis</em> in the former historic range of the species to assess the potential for possible re-colonization. We used a remotely-sensed image and geographic information systems (GIS) to create a land-use/land (LU/LC) binary cover map, from which we calculated the habitat suitability index (HSI) based on an estimated home range of 50ha. A sensitivity analysis revealed the necessity for more data to make an accurate estimate, but our analysis of landscape metrics indicates more than 930ha of suitable habitat patches. These patches are heavily fragmented and mostly located on private lands. They can be assessed for understory and herbaceous vegetation and can be restored for possible re-establishment of approximately 18 groups/colonies of Red-cockaded Woodpeckers.</p><div> </div>

<p>The avifaunal diversity of Chamba District of Himachal Pradesh with emphasis on Kalatop-Khajjiar Wildlife Sanctuary and its surrounding was observed for a period of one year between 2012 and 2013. We observed 95 species of birds belonging to 12 orders and 40 families. Of this diversity, 41 species were abundant to common, 34 occasional and 20 rare. Most species were resident (83 species, including two species whose population increased during winters) and the rest were migrants (including nine winter migrating species and three summer migrating species). A total of 302 species of birds have been reported from Chamba District between 1884 and present. Analysis of recent published literature in conjunction with the present study reveals that 178 species of birds have been reported from Chamba District since 2000. The present study reports 11 new records for the district.</p><div> </div>

Published: January 2016

<p>The status of the Fishing Cat <em>Prionailurus viverrinus</em> in Koshi Tappu Wildlife Reserve, Nepal was assessed by camera trapping and pugmark searches from 2011 to 2014. The reserve is a highly dynamic and unstable snow-fed braided river system with many anabranches and islands. Evidence of Fishing Cats was found throughout most of the reserve. They were probably more abundant on the eastern side, among the islands of the main river channel, and in the adjacent buffer zone where there was a chain of fishponds and marsh areas fed by seepage from the main river channel. Evidence of Fishing Cats was found up to 6km north of the reserve on the Koshi River but not beyond this. The population is probably small and may be isolated but given the endangered status of the species, is significant. The main likely threats identified are wetland and riparian habitat deterioration caused by over exploitation and illegal grazing by villagers, overfishing of wetlands and rivers within the reserve, and direct persecution arising from perceived conflicts with fish farming and poultry husbandry. Required conservation actions are discussed.</p><div> </div>

Change in Tropical Cyclone Activity during the Break of the Western North Pacific Summer Monsoon in Early August
Authors: Xu Ke , Lu Riyu 
Published: January 2016

Abstract
The modulation of tropical cyclone (TC) activity by the western North Pacific (WNP) monsoon break is investigated by analyzing the subseasonal evolution of TCs and corresponding circulations, based on 65 years of data from 1950 to 2014. The monsoon break has been identified as occurring over the WNP in early August. The present results show that TC occurrence decreases (increases) remarkably to the east of the Mariana Islands (southeast of Japan) during the monsoon break, which is closely related to local anomalous midtropospheric downward (upward) motion and lower-tropospheric anticyclonic (cyclonic) circulation, in comparison with the previous and subsequent convective periods in late July and mid-August. These changes of TC activity and the corresponding circulation during the monsoon break are more significant in typical monsoon break years when the monsoon break phenomenon is predominant. The reverse changes of TC activity to the east of the Mariana Islands and to the southeast of Japan during the monsoon break are closely associated with the out-of-phase subseasonal evolutions over these two regions from late July to mid-August, which are both contributed to greatly by 10–25-day oscillations. Finally, the roles of midlatitude and tropical disturbances on 10–25-day oscillations are also discussed.

Authors: Horger Stephanie , Kandrac Stacy , Longyhore Daniel S. 
Published: January 2016

Objective: To report a case of dysgeusia and dysosmia following midodrine initiation. Methods/Case Summary: A 58-year-old male started midodrine 5 mg tablets 3 times a day for orthostatic hypotension. Two weeks after starting, he began complaining of dysgeusia and dysosmia. He also reported less of an appetite at this time but did not realize it was due to symptoms. He reported his symptoms as tolerable and chose to continue the medicine. At follow-up contact 7 days later, the symptoms were still present but diminishing. Main results/Discussion: Midodrine is used for symptoms of orthostatic hypotension. Dysgeusia and dysosmia are not common adverse events and are not included in the manufacturer’s labeling. There is only one other published case report of this reaction. Our patient only admitted to slight appetite suppression, but it may be more profound in some. The reaction may be dose related, but there is not enough information to make this conclusion. Principal conclusions: Using midodrine may result in dysgeusia and dysosmia. According to this case, both adverse effects may lessen or resolve over time with the use of the medication.
Eppur Si Muove: vitamin D is essential in preventing and modulating SLE
Authors: Azrielant S , Shoenfeld Y 
Published: January 2016

Systemic lupus erythematosus (abbreviated SLE or lupus) is a systemic autoimmune disease, with genetic, immunologic, hormonal, and environmental factors. 1 One of the environmental factors that has been studied over the years is vitamin D, which is created in the human body in response to exposure to sunlight and ultraviolet (UV) radiation. This review aims at examining findings from recent years, specifically 2013–2014, regarding the relationship between vitamin D deficiency and SLE flares, severity, and clinical manifestation, as well as to examine the treatment options derived from this relationship.
From painful busyness to emotional immunization: Nurses’ experiences of ethical challenges
Authors: Storaker Anne , Nåden Dagfinn , Sæteren Berit 
Published: January 2016

Background: The professional values presented in ethical guidelines of the Norwegian Nurses Organisation and International Council of Nurses describe nurses’ professional ethics and the obligations that pertain to good nursing practice. The foundation of all nursing shall be respect for life and the inherent dignity of the individual. Research proposes that nurses lack insight in ethical competence and that ethical issues are rarely discussed on the wards. Furthermore, research has for some time confirmed that nurses experience moral distress in their daily work and that this has become a major problem for the nursing profession. Objectives: The purpose of this article is to obtain a deeper understanding of the ethical challenges that nurses face in daily practice. The chosen research questions are “What ethical challenges do nurses experience in their daily practice?” Research design: We conducted a qualitative interview study using a hermeneutical approach to analyzing data describing nurses’ experiences. Ethical considerations: The Norwegian Social Science Data services approved the study. Furthermore, the head of the hospital gave permission to conduct the investigation. The requirement of anonymity and proper data storage in accordance with the World Medical Association Declaration of Helsinki was met. Method and results: The context for the study comprised three different clinical wards at a university hospital in Norway. Nine qualified nurses were interviewed. The results were obtained through a systematic development beginning with the discovery of busyness as a painful phenomenon that can lead to conflicts in terms of ethical values. Furthermore, the consequences compromising professional principles in nursing care emerged and ended in moral blindness and emotional immunization of the healthcare providers. Emotional immunization occurred as a new dimension involving moral blindness and immunity in relation to being emotionally touched.
Recommendations for Kübler Index standardization
Authors: Warr L.N. , Ferreiro Mählmann R. 
Published: January 2016

AbstractFollowing a round-table discussion at the Mid-European Clay Conference in Dresden 2014, new recommendations for illite ‘crystallinity’ Kübler index standardization have been agreed upon. The use of Crystallinity Index standards in the form of rock-fragment samples will be continued, along with the same numerical scale of measurement presented by Warr & Rice (1994). However, in order to be compatible with the original working definition of Kübler's (1967) anchizone, the upper and lower boundary limits of the Crystallinity Index Standard (CIS) scale are adjusted appropriately from 0.25°2θ and 0.42°2θ to 0.32°2θ and 0.52°2θ. This adjustment is based on an inter-laboratory correlation between the laboratories of Basel, Neuchâtel and the CIS scale. The details of this correction are presented in this first note, as discussed at the round-table meeting and will be further substantiated by a correlation program between CIS and former Kübler–Frey–Kisch standards.
Realistic molecular cluster models for exfoliated kaolinite
Authors: Táborosi Attila , Szilagyi Robert K. 
Published: January 2016

AbstractMolecular cluster models, developed for an exfoliated kaolinite, provide a structural description comparable to that of periodic slab models for a fraction of the computational cost. These models include both the octahedral and the tetrahedral sheets of kaolinite. The first-generation model (G1) contains the inner and outer coordination sphere of the Al- and Si-honeycombs as the preferred sites for adsorption of small organic molecules. Since no experimental information is available to date at the atomic level for exfoliated kaolinite, we carried out a systematic density functional theory evaluation for establishing the most reasonable coordinates of the ions and groups. The results of molecular cluster and periodic calculations were utilized for evaluating semi-empirical Hamiltonians on larger models. Using a PM7 Hamiltonian, the structure of cluster models containing 1 + 6 (second generation) and 1 + 6 + 12 (third generation) Al- and Si-honeycombs which are out of reach for ab initio calculations, were determined. These molecular slab models offer a structural platform for adsorption, intercalation and delamination studies.
Surface structure of organoclays as examined by X-ray photoelectron spectroscopy and molecular dynamics simulations

Published: January 2016

AbstractOrganoclays are sorbent materials prepared from clays by exchanging inorganic with organic cations. Their properties depend on the loading and conformational structure of the organic cations, but little information is available about the surface structures of organoclays. In this work, X-ray photoelectron spectroscopy (XPS) and classical molecular dynamics (MD) simulations are combined to characterize the external interface of an organoclay prepared from hexadecylpyridinium (HDPy+) and bentonite. The XPS survey spectra show well the varying elemental composition of the surface with increasing amount of surfactant, showing a decreasing contribution of clay-derived elements with increasing organic coverage. The high-resolution C 1s XPS spectra depict sensitively the surface arrangement of the surfactant. In combination with MD simulations, the results implied a monolayer coating for low surfactant coverage and a disordered bilayer arrangement at high surfactant uptakes. Molecular dynamics simulations showed that for very high cation uptake a quasi-paraffin-like configuration is also possible. The combination of experimental and modelling methods yielded congruent information on the molecular-scale arrangement of organic cations at the organoclay surfaces and the controlling mechanisms.
Hydro-mechanical properties of Calcigel-polyacrylamide composites
Authors: Haase Hanna , Schanz Tom 
Published: January 2016

AbstractCalcigel bentonite-polyacrylamide (PAA) composites were investigated for their formation characteristics and their macroscopic hydro-mechanical and microscopic structural properties. The composites prepared were different in terms of the polymer charge, i.e. cationic (PAA+), anionic (PAA−), non-ionic (PAA°) and in terms of the polymer-to-clay ratio. The latter varied according to the individual maximum sorption capacity established from adsorption isotherms. Oedometer and waterretention testswere conducted on composites prepared under initial slurry conditions. The microstructure of the composites was investigated using environmental scanning electron microscopy (ESEM). At low stress, distinctly increased void ratios were found for all types of the composites, whereas under highstress conditions only the PAA+-composite prepared at 100% of the maximum sorption capacity showed an increase in void ratio. Analyses by ESEM on this composite indicated structural changes related to the preferential face-to-face aggregation, which help to explain the macroscopic behaviour and also account for the increased hydraulic permeabilities observed.

Abstract
Background
The outcomes of patients admitted to the intensive care unit (ICU) for acute manifestation of small-vessel vasculitis are poorly reported. The aim of the present study was to determine the mortality rate and prognostic factors of patients admitted to the ICU for acute small-vessel vasculitis.

Methods
This retrospective, multicenter study was conducted from January 2001 to December 2014 in 20 ICUs in France. Patients were identified from computerized registers of each hospital using the International Classification of Diseases, Ninth Revision (ICD-9). Inclusion criteria were (1) known or highly suspected granulomatosis with polyangiitis, eosinophilic granulomatosis with polyangiitis, microscopic polyangiitis (respectively, ICD-9 codes M31.3, M30.1, and M31.7), or anti–glomerular basement membrane antibody disease (ICD-9 codes N08.5X-005 or M31.0+); (2) admission to the ICU for the management of an acute manifestation of vasculitis; and (3) administration of a cyclophosphamide pulse in the ICU or within 48 h before admission to the ICU. The primary endpoint was assessment of mortality rate 90 days after admission to the ICU.

Results
Eighty-two patients at 20 centers were included, 94 % of whom had a recent (<6 months) diagnosis of small-vessel vasculitis. Forty-four patients (54 %) had granulomatosis with polyangiitis. The main reasons for admission were respiratory failure (34 %) and pulmonary-renal syndrome (33 %). Mechanical ventilation was required in 51 % of patients, catecholamines in 31 %, and renal replacement therapy in 71 %. Overall mortality at 90 days was 18 % and the mortality in ICU was 16 %. The main causes of death in the ICU were disease flare in 69 % and infection in 31 %. In univariable analysis, relevant factors associated with death in nonsurvivors compared with survivors were Simplified Acute Physiology Score II (median [interquartile range] 51 [38–82] vs. 36 [27–42], p = 0.005), age (67 years [62–74] vs. 58 years [40–68], p < 0.003), Sequential Organ Failure Assessment score on the day of cyclophosphamide administration (11 [6–12] vs. 6 [3–7], p = 0.0004), and delayed administration of cyclophosphamide (5 days [3–14] vs. 2 days [1–5], p = 0.0053).

Conclusions
Patients admitted to the ICU for management of acute small-vessel vasculitis benefit from early, aggressive intensive care treatment, associated with an 18 % death rate at 90 days.
Metabolic Benefit of Chronic Caloric Restriction and Activation of Hypothalamic AGRP/NPY Neurons in Male Mice Is Independent of Ghrelin

Published: January 2016

Abstract
Aging is associated with attenuated ghrelin signaling. During aging, chronic caloric restriction (CR) produces health benefits accompanied by enhanced ghrelin production. Ghrelin receptor (GH secretagogue receptor 1a) agonists administered to aging rodents and humans restore the young adult phenotype; therefore, we tested the hypothesis that the metabolic benefits of CR are mediated by endogenous ghrelin. Three month-old male mice lacking ghrelin (Ghrelin−/−) or ghrelin receptor (Ghsr−/−), and their wild-type (WT) littermates were randomly assigned to 2 groups: ad libitum (AL) fed and CR, where 40% food restriction was introduced gradually to allow Ghrelin−/− and Ghsr−/− mice to metabolically adapt and avoid severe hypoglycemia. Twelve months later, plasma ghrelin, metabolic parameters, ambulatory activity, hypothalamic and liver gene expression, as well as body composition were measured. CR increased plasma ghrelin and des-acyl ghrelin concentrations in WT and Ghsr−/− mice. CR of WT, Ghsr−/−, and Ghrelin−/− mice markedly improved metabolic flexibility, enhanced ambulatory activity, and reduced adiposity. Inactivation of Ghrelin or Ghsr had no effect on AL food intake or food anticipatory behavior. In contrast to the widely held belief that endogenous ghrelin regulates food intake, CR increased expression of hypothalamic Agrp and Npy, with reduced expression of Pomc across genotypes. In the AL context, ablation of ghrelin signaling markedly inhibited liver steatosis, which correlated with reduced Pparγ expression and enhanced Irs2 expression. Although CR and administration of GH secretagogue receptor 1a agonists both benefit the aging phenotype, we conclude the benefits of chronic CR are a consequence of enhanced metabolic flexibility independent of endogenous ghrelin or des-acyl ghrelin signaling.
Gata2 Is a Rheostat for Mesenchymal Stem Cell Fate in Male Mice

Published: January 2016

Abstract
Gata2 is a zinc finger transcription factor that is important in hematopoiesis and neuronal development. However, the roles of Gata2 in the mesenchymal lineages are poorly understood. In vitro studies suggest that Gata2 modulates adipocyte differentiation and mesenchymal stem cell (MSC) proliferation. To systematically determine the in vivo functions of Gata2 in the MSC lineage commitment and development, we have generated three mouse models in which Gata2 is specifically deleted in MSCs, adipocytes, or osteoblasts. During the MSC expansion stage, Gata2 promotes proliferation and attenuates differentiation; thereby Gata2 loss in MSCs results in enhanced differentiation of both adipocytes and osteoblasts. During the differentiation stage, Gata2 also plays MSC-independent roles to impede lineage commitment; hence, Gata2 loss in adipocyte or osteoblast lineages also augments adipogenesis and osteoblastogenesis, respectively. These findings reveal Gata2 as a crucial rheostat of MSC fate to control osteoblast and adipocyte lineage development.
Geology and taphonomy of the base of the Taquaral Member, Irati Formation (Permian, Paraná Basin), Brazil
Authors: Chahud Artur , Petri Setembrino 
Published: January 2016

AbstractThe taphonomy of Early Permian vertebrates from a sandy facies at the base of the Taquaral Member, Irati Formation, was surveyed in order to acquire data for the interpretation of the sedimentary processes and paleoenvironment of deposition. Six outcrops from the Rio Claro municipality and surrounding areas, from the Brazilian State of São Paulo, were investigated. The vertebrate groups are Chondrichthyes (Xenacanthiformes, Ctenacanthiformes and Petalodontiformes), Osteichthyes (Actinopterygii and Sarcopterygii) and Tetrapodomorpha. They occur as loose teeth, scales, spines and bone remains. The sandy facies is characterized by fining upward deposition. The coarser sandstone immediately above the underlying Tatuí Formation is rich in Chondrichthyes. However, the fine sandstone above, immediately beneath the silty shale facies, is devoid of Chondrichthyes, though Osteichthyes scales, teeth and bones were present. The taphonomy is important for inferring sedimentary processes and then the paleoenvironments. The poor sorting of the sandstone and the presence of fossils that are mostly abraded or worn are indicative of a high energy environment. In contrast, the presence of fossils in a good state of preservation, some without abrasion and breakages are indicative of only limited transport. Differences of fossil spatial density, numbers of specimens and taxa may be explained by the dynamics of deposition, from details of the palaeoenvironment can be obtained.
