Review of American fossil phlebotominae (Diptera: Psychodidae) with a description of two new species

The objective of this study was to carry out a taxonomic review of fossil American phlebotomine sand flies and describe two new species found in amber in the Dominican Republic. The gonostyle of one of these, Micropygomyia dorafeliciangeliae nov. sp., (=Lutzomyia dorafeliciangeliae, species group oswaldoi), has five spines, similar to that of Micropygomyia paterna (Quate, 1963) (= Lutzomyia paterna, species group oswaldoi), but they may be distinguished by the alpha/gamma ratio, which is <1.0 in the new species and >1 in the latter. Pintomyia dominicana nov. sp. (=Lutzomyia dominicana, species group verrucarum) has four spines on the gonostyle and presents a long bristle on the apex of the paramere, which distinguishes it from the other fossil species. With the description of these two new species, a total of 14 species of the American fossil phlebotomine sand flies has been described, 10 of which belong to the genus Pintomyia. An identification key for male fossil species is presented

Description of Skermanella parooensis gen. nov., sp. nov. to accommodate Conglomeromonas largomobilis subsp. parooensis following the transfer of Conglomeromonas largomobilis subsp. largomobilis to the genus Azospirillum

As a consequence of the transfer of the type species Conglomeromonas largomobilis subsp. largomobilis to the genus Azospirillum, the name of the genus Conglomeromonas must be changed in accordance with Rule 37a(1) of the International Code of Nomenclature of Bacteria. Consequently, it is proposed that the subspecies Conglomeromonas largomobilis subsp, parooensis be transferred to the genus Skermanella gen, nov. as the type species Skermanella parooensis gen, nov., sp, nov. This taxon belongs to an isolated subline of descent in the Azospirillum branch of the alpha-Proteobacteria. The spelling of the specific epithet of Azospirillum largomobile is corrected to Azospirillum largimobile.

Phylogenetic relationships among members of the Comamonadaceae, and description of Delftia acidovorans (den Dooren de Jong 1926 and Tamaoka et al. 1987) gen. nov., comb. nov.

The phylogenetic relationships among members of the family Comamonadaceae and several unclassified strains were studied by direct sequencing of their PCR-amplified 16S rRNA genes. Based on the 16S rRNA gene sequence analysis, members of the family formed a coherent group. The closest relatives are species of the Rubrivivax sub-group: Leptothrix discophora, Ideonella dechloratans and Rubrivivax gelatinosus. The genus Hydrogenophaga formed two subclusters, as did the species of Acidovorax, whereas the five species of the genus [Aquaspirillum] were polyphyletic. Comamonas acidovorans was phylogenetically distant from the type species of Comamonas, Comamonas terrigena. On the basis of this work and previous studies, Comamonas acidovorans is removed from the genus Comamonas and renamed as Delftia acidovorans gen. nov., comb, nov. Descriptions of the new genus Delftia and of the type species Delftia acidovorans, for which the type strain is ATCC 15668(T), are presented.

Description of Gluconacetobacter sacchari sp. nov., a new species of acetic acid bacterium isolated from the leaf sheath of sugar cane and from the pink sugar-cane mealy bug

A new species of the genus Gluconacetobacter, for which the name Gluconacetobacter sacchari sp. nov. is proposed, was isolated from the leaf sheath of sugar cane and from the pink sugar-cane mealy bug, Saccharicoccus sacchari, found on sugar cane growing in Queensland and northern New South Wales, Australia, The nearest phylogenetic relatives in the alpha-subclass of the Proteobacteria are Gluconacetobacter liquefaciens and Gluconacetobacter diazotrophicus, which have 98.8-99.3% and 97.9-98.5% 16S rDNA sequence similarity, respectively, to members of Gluconacetobacter sacchari. On the basis of the phylogenetic positioning of the strains, DNA reassociation studies, phenotypic tests and the presence of the Q10 ubiquinone, this new species was assigned to the genus Gluconacetobacter. No single phenotypic characteristic is unique to the species, but the species can be differentiated phenotypically from closely related members of the acetic acid bacteria by growth in the presence of 0.01% malachite green, growth on 30% glucose, an inability to fix nitrogen and an inability to grow with the L-amino acids asparagine, glycine, glutamine, threonine and tryptophan when D-mannitol was supplied as the sole carbon and energy source. The type strain of this species is strain SRI 1794(T) (= DSM 12717(T)).

Intergeneric phylogenetic relationships in catfishes of the Loricariinae (Siluriformes: Loricariidae), with the description of Fonchiiloricaria nanodon: a new genus and species from Peru

Recent investigations in the upper Rio Huallaga in Peru revealed the presence of an intriguing species of the Loricariinae. To characterize and place this species within the evolutionary tree of the subfamily, a molecular phylogeny of this group was inferred based on the 12S and 16S mitochondrial genes and the nuclear gene F-reticulon4. The phylogeny indicated that this distinctive species was a member of the subtribe Loricariina. Given its phylogenetic placement, and its unusual morphology, this species is described as a new genus and new species of Loricariinae: Fonchiiloricaria nanodon. This new taxon is diagnosed by usually possessing one to three premaxillary teeth that are greatly reduced; lips with globular papillae on the surface; the distal margin of lower lip bearing short, triangular filaments; the premaxilla greatly reduced; the abdomen completely covered by plates, with the plates between lateral abdominal plates small and rhombic; a caudal fin with 14 rays; the orbital notch absent; five lateral series of plates; dorsal-fin spinelet absent; preanal plate present, large and solid, and of irregular, polygonal shape, the caudal peduncle becoming more compressed posteriorly for the last seven to 10 plates.

A review of Skutzia Reiss, 1985, with the description of three new species (Diptera:Chironomidae:Chironominae)

Skutzia epleri sp. n. from USA, S. inthanonensis sp. n. from Thailand, and S. quetzali sp. n. from Panama and Mexico are described and figured as male imagines, and S. gaianii Andersen is recorded from Trinidad and Tobago. The genus now consists of 6 species. In addition to the species mentioned above, S. inopinata Reiss from Canada and S. bahiensis Reiss from Brazil are included. Skutzia is placed in the subtribe Zavreliina of the tribe Tanytarsini, but because the immatures are not known, this placement must be regarded as tentative. The distribution of the genus, previously known only from the Nearctic and the Neotropical regions, is expanded to include the Oriental region, indicating a Beringian connection. An emended diagnosis and a key to the males of Skutzia are provided.

Opposite clinical phenotypes of glucokinase disease: Description of a novel activating mutation and contiguous inactivating mutations in human glucokinase (GCK) gene.

Glucokinase is essential for glucose-stimulated insulin release from the pancreatic beta-cell, serving as glucose sensor in humans. Inactivating or activating mutations of glucokinase lead to different forms of glucokinase disease, i.e. GCK-monogenic diabetes of youth, permanent neonatal diabetes (inactivating mutations), and congenital hyperinsulinism, respectively. Here we present a novel glucokinase gene (GCK)-activating mutation (p.E442K) found in an infant with neonatal hypoglycemia (1.5 mmol/liter) and in two other family members suffering from recurrent hypoglycemic episodes in their childhood and adult life. In contrast to the severe clinical presentation in the index case, functional studies showed only a slight activation of the protein (relative activity index of 3.3). We also report on functional studies of two inactivating mutations of the GCK (p.E440G and p.S441W), contiguous to the activating one, that lead to monogenic diabetes of youth. Interestingly, adult family members carrying the GCK pE440G mutation show an unusually heterogeneous and progressive diabetic phenotype, a feature not typical of GCK-monogenic diabetes of youth. In summary, we identified a novel activating GCK mutation that although being associated with severe neonatal hypoglycemia is characterized by the mildest activation of the glucokinase enzyme of all previously reported.

International registry on splanchnic vein thrombosis: description of the study population

Background: Splanchnic vein thrombosis (SVT) is an uncommon, butpotentially life-threatening disease. Aim of this ISTH based registryis to improve the knowledge on SVT by studying a large, international,unselected population.Methods: Consecutive patients with objectively diagnosed SVT areeligible for the registry. Information on clinical presentations, diagnosticapproaches, risk factors, therapeutic approaches, and recurrencesof SVT, bleedings and deaths at a 2 year follow up are enteredon a website database (www.svt.altervista.org). We planned a samplesize of 500 patients, including all sites of thrombosis.Results: As of December 31st, 2010, 429 patients with SVT (85.8%of the planned sample) have been enrolled at 25 centres from sevencountries. The mean age is 52.6 years (range 16-85 years); 62.2% aremales, 67.8% are Caucasians, and 31.2% Asians. SVT occurred inmultiple vein segments in 36.4% of patients, 40.5% of patients hadisolated portal vein thrombosis, 11.9% of patients had mesentericvein thrombosis, 7.5% had supra-hepatic vein thrombosis, and 3.6%had splenic vein thrombosis. Abdominal pain was the most commonsymptom occurring in 56.6% of the patients; 9.5% of patients hadgastrointestinal bleeding at the time of diagnosis; 25.4% of patientswith SVT were asymptomatic. Mean time between onset of symptomsand diagnosis was 7.4 days. Objective diagnosis was obtained withabdominal CT in 79.9% of patients. Most common risk factors atthe time of diagnosis included cancer (24.1%), cirrhosis (23.1%), andhematological disorders (15.4%); in 15.9% of patients SVT was idiopathic.Most patients were treated with anticoagulant drugs: 30.8%with parenteral drugs only, 56.9% with parenteral drugs followed byvitamin K antagonists.Conclusions: SVT is a major challenge for experts in thrombosis andhemostasis. Large collaborative studies are necessary to improve theunderstanding and the management of this heterogeneous disease.

Suitability of GRIND-based principal properties for the description of molecular similarity and ligand-based virtual screening

The information provided by the alignment-independent GRid Independent Descriptors (GRIND) can be condensed by the application of principal component analysis, obtaining a small number of principal properties (GRIND-PP), which is more suitable for describing molecular similarity. The objective of the present study is to optimize diverse parameters involved in the obtention of the GRIND-PP and validate their suitability for applications, requiring a biologically relevant description of the molecular similarity. With this aim, GRIND-PP computed with a collection of diverse settings were used to carry out ligand-based virtual screening (LBVS) on standard conditions. The quality of the results obtained was remarkable and comparable with other LBVS methods, and their detailed statistical analysis allowed to identify the method settings more determinant for the quality of the results and their optimum. Remarkably, some of these optimum settings differ significantly from those used in previously published applications, revealing their unexplored potential. Their applicability in large compound database was also explored by comparing the equivalence of the results obtained using either computed or projected principal properties. In general, the results of the study confirm the suitability of the GRIND-PP for practical applications and provide useful hints about how they should be computed for obtaining optimum results.
