A chromosomelevel genome assembly of the Asian arowana, Scleropages formosus

Asian arowana (Scleropages formosus), an ancient teleost belonging to the Order Osteoglossomorpha, has been a valuable ornamental fish with some varieties. However, its biological studies and breeding germplasm have been remarkably limited by the lack of a reference genome. To solve these problems, here we report high-quality genome sequences of three common varieties of Asian arowana (the golden, red and green arowana). We firstly generated a chromosome-level genome assembly of the golden arowana, on basis of the genetic linkage map constructed with the restriction site-associated DNA sequencing (RAD-seq). In addition, we obtained draft genome assemblies of the red and green varieties. Finally, we annotated 22,016, 21,256 and 21,524 protein-coding genes in the genome assemblies of golden, red and green varieties respectively. Our data were deposited in publicly accessible repositories to promote biological research and molecular breeding of Asian arowana

The Hubbard model within the equations of motion approach

The Hubbard model has a special role in Condensed Matter Theory as it is considered as the simplest Hamiltonian model one can write in order to describe anomalous physical properties of some class of real materials. Unfortunately, this model is not exactly solved except for some limits and therefore one should resort to analytical methods, like the Equations of Motion Approach, or to numerical techniques in order to attain a description of its relevant features in the whole range of physical parameters (interaction, filling and temperature). In this manuscript, the Composite Operator Method, which exploits the above mentioned analytical technique, is presented and systematically applied in order to get information about the behavior of all relevant properties of the model (local, thermodynamic, single- and two- particle ones) in comparison with many other analytical techniques, the above cited known limits and numerical simulations. Within this approach, the Hubbard model is shown to be also capable to describe some anomalous behaviors of the cuprate superconductors.Comment: 232 pages, more than 300 figures, more than 500 reference

The Asian arowana (<i>Scleropages formosus</i>) genome provides new insights into the evolution of an early lineage of teleosts

The Asian arowana (Scleropages formosus), one of the world’s most expensive cultivated ornamental fishes, is an endangered species. It represents an ancient lineage of teleosts: the Osteoglossomorpha. Here, we provide a high-quality chromosome-level reference genome of a female golden-variety arowana using a combination of deep shotgun sequencing and high-resolution linkage mapping. In addition, we have also generated two draft genome assemblies for the red and green varieties. Phylogenomic analysis supports a sister group relationship between Osteoglossomorpha (bonytongues) and Elopomorpha (eels and relatives), with the two clades together forming a sister group of Clupeocephala which includes all the remaining teleosts. The arowana genome retains the full complement of eight Hox clusters unlike the African butterfly fish (Pantodon buchholzi), another bonytongue fish, which possess only five Hox clusters. Differential gene expression among three varieties provides insights into the genetic basis of colour variation. A potential heterogametic sex chromosome is identified in the female arowana karyotype, suggesting that the sex is determined by a ZW/ZZ sex chromosomal system. The high-quality reference genome of the golden arowana and the draft assemblies of the red and green varieties are valuable resources for understanding the biology, adaptation and behaviour of Asian arowanas

Hyaluronic acid improves pain symptoms more than bladder storage symptoms in women with interstitial cystitis

Objective: Intravesical hyaluronic acid (HA) therapy is one of acceptable methods to treat bladder pain and storage symptoms (i.e., urgency, frequency and nocturia) of interstitial cystitis/bladder pain syndrome (IC/BPS). We aim to assess the impacts of intravesical HA on bladder pain and storage symptoms, respectively, and to investigate their associated factors in patients with IC/BPS. Materials and methods: In this prospective, multicenter study, 103 women with refractory IC/BPS undergoing a standard protocol of intravesical HA therapy were enrolled. A pain Visual Analog Scale (VAS) and the Interstitial Cystitis Symptom and Problem Index (ICSI & ICPI) were used to assess symptoms and bother associated with IC/BPS. The Scaled Global Response Assessment (GRA) was used to evaluate patients' perception of overall changes in bladder pain and storage symptoms, respectively, after treatment. Results: Mean age of participants was 43.6 ± 11.8 years. The average duration of symptoms was 5.1 ± 5.0 years. Significant improvements in pain VAS, ICSI and ICPI scores were observed after treatment. However, patients reported significantly different rates of moderate/marked improvement in bladder pain and storage symptoms (73.8% vs. 47.6%; P < 0.001) on the GRA, respectively. “Lower pain VAS score” and “reduced functional bladder capacity” were found to be the factors that adversely affected the treatment responses of bladder pain and storage symptoms, respectively, after repeated statistical analyses. Conclusion: Bladder instillation of HA seemed more efficient in improving bladder pain than storage symptoms associated with IC/BPS. The persistence of bladder storage symptoms after treatment might result from a reduced functional bladder capacity.
