Familiarity with, perceptions of and attitudes toward butterflies of urban park users in megacities across East and Southeast Asia.

Perceptions of, and attitudes toward, wildlife are influenced by exposure to, and direct experiences with, nature. Butterflies are a conspicuous and ubiquitous component of urban nature across megacities that are highly urbanized with little opportunity for human-nature interactions. We evaluated public familiarity with, perceptions of and attitudes toward butterflies across nine megacities in East and Southeast Asia through face-to-face interviews with 1774 urban park users.

Coagulation factor protein abundance in the pre-septic state predicts coagulopathic activities that arise during late-stage murine sepsis.

Background: Although sepsis accounts for 1 in 5 deaths globally, few molecular therapies exist for this condition. The development of effective biomarkers and treatments for sepsis requires a more complete understanding of host responses and pathogenic mechanisms at early stages of disease to minimize host-driven pathology.

Methods: An alternative to the current symptom-based approach used to diagnose sepsis is a precise assessment of blood proteomic changes during the onset and progression of Salmonella Typhimurium (ST) murine sepsis.

First record of the Cyrtodactylus brevipalmatus group (Squamata: Gekkonidae) from Vietnam with description of a new species.

A new species of the genus Cyrtodactylus is described from Dien Bien Province, northwestern Vietnam based on morphological and molecular data. Cyrtodactylus ngati sp. nov.

Two new and potentially highly threatened Megophrys Horned frogs (Amphibia: Megophryidae) from Indochina's highest mountains.

Megophrys are a group of morphologically conserved, primarily forest-dependent frogs known to harbour cryptic species diversity. In this study, we examined populations of small-sized Megophrys from mid- and high elevation locations in the Hoang Lien Range, northern Vietnam. On the basis of morphological, molecular and bioacoustic data, individuals of these populations differed from all species of Megophrys known from mainland Southeast Asia north of the Isthmus of Kra and from neighbouring provinces in China.

A new species of Leptolalax (Anura: Megophryidae) from Son Tra Peninsula, central Vietnam.

Morphological, acoustic and molecular analyses result in the description of Leptolalax rowleyae sp. nov., a new species of frog in the Megophryidae, belonging to the L.

A new species of Cyrtodactylus (Squamata: Gekkonidae) from Ninh Binh Province, Vietnam.

We describe a new species of the genus Cyrtodactylus on the basis of six specimens collected from the limestone forest of the Van Long Wetland Nature Reserve, Ninh Binh Province, Vietnam. Cyrtodactylus soni sp. nov.

New provincial records of skinks (Squamata: Scincidae) from northwestern Vietnam.

We report six new records of skinks from northwestern Vietnam: Eutropis macularius, Scincelladevorator , S.monticola, S.ochracea, Sphenomorphuscryptotis and S.

Systemic mastocytosis in association with chronic lymphocytic leukemia and plasma cell myeloma.

Systemic mastocytosis with associated clonal haematological non-mast cell lineage disease (SM-AHNMD) is a heterogeneous group of mast cell disorders with different clinical, pathologic and underlying molecular characteristics. While myelomonocytic/myeloid neoplasia overwhelmingly predominates the AHNMD component, lymphoproliferative disorders rarely occur as an AHNMD component of SM-AHNMD. Here we report two cases of SM-AHNMD, in which the AHNMD component is chronic lymphocytic leukemia in one case, and concurrent chronic lymphocytic leukemia as well as plasma cell myeloma in another case.

Physiological and glycomic characterization of N-acetylglucosaminyltransferase-IVa and -IVb double deficient mice.

N-Acetylglucosaminyltransferase-IV (GnT-IV) has two isoenzymes, GnT-IVa and GnT-IVb, which initiate the GlcNAcbeta1-4 branch synthesis on the Manalpha1-3 arm of the N-glycan core thereby increasing N-glycan branch complexity and conferring endogenous lectin binding epitopes. To elucidate the physiological significance of GnT-IV, we engineered and characterized GnT-IVb-deficient mice and further generated GnT-IVa/-IVb double deficient mice. In wild-type mice, GnT-IVa expression is restricted to gastrointestinal tissues, whereas GnT-IVb is broadly expressed among organs.

In vitro sonothrombolysis with duplex ultrasound: first results using a simplified model.

Background: The main aim was to study the effects of ultrasound (US) alone, in combination with an US contrast agent (UCA), tissue plasminogen activator (tPA), or the combination of both upon blood clots.

Methods: In order to learn about sonothrombolysis with diagnostic duplex US, a simplified in vitro test model, using human whole blood clots in Petri dishes, was established.

Results: A total of 286 blood clots were analyzed.

The Ashwell receptor mitigates the lethal coagulopathy of sepsis.

The Ashwell receptor, the major lectin of hepatocytes, rapidly clears from blood circulation glycoproteins bearing glycan ligands that include galactose and N-acetylgalactosamine. This asialoglycoprotein receptor activity remains a key factor in the development and administration of glycoprotein pharmaceuticals, yet a biological purpose of the Ashwell receptor has remained elusive. We have identified endogenous ligands of the Ashwell receptor as glycoproteins and regulatory components in blood coagulation and thrombosis that include von Willebrand factor (vWF) and platelets.

Sialyltransferase ST3Gal-IV operates as a dominant modifier of hemostasis by concealing asialoglycoprotein receptor ligands.

A number of poorly characterized genetic modifiers contribute to the extensive variability of von Willebrand disease, the most prevalent bleeding disorder in humans. We find that a genetic lesion inactivating the murine ST3Gal-IV sialyltransferase causes a bleeding disorder associated with an autosomal dominant reduction in plasma von Willebrand factor (VWF) and an autosomal recessive thrombocytopenia. Although both ST3Gal-IV and ST6Gal-I sialyltransferases mask galactose linkages implicated as asialoglycoprotein receptor ligands, only ST3Gal-IV deficiency promotes asialoglycoprotein clearance mechanisms with a reduction in plasma levels of VWF and platelets.
