Deafness DFNB9, caused by mutations in the gene encoding otoferlin, might be treated by transferring wild-type otoferlin cDNA into IHCs, which is difficult due to the large size of this transgene. In this study, we generated two adeno-associated viruses (AAVs), each containing half of the otoferlin cDNA Co-injecting these dual-AAV2/6 half-vectors into the cochleae of 6- to 7-day-old otoferlin knock-out () mice led to the expression of full-length otoferlin in up to 50% of IHCs.

Selective deletion of hepatocyte platelet-derived growth factor receptor α and development of liver fibrosis in mice.

Cell Commun Signal 2018 Dec 3;16(1):93. Epub 2018 Dec 3.

Department of Internal Medicine, Gangnam Severance Hospital, Yonsei University College of Medicine, Seoul, Republic of Korea.

Background: Platelet-derived growth factor receptor α (PDGFRα) expression is increased in activated hepatic stellate cells (HSCs) in cirrhotic liver, while normal hepatocytes express PDGFRα at a negligible level. However, cancerous hepatocytes may show upregulation of PDGFRα, and hepatocellular carcinoma is preceded by chronic liver injury. The role of PDGFRα in non-cancerous hepatocytes and liver fibrosis is unclear. Read More

Time-dependent physico-chemical changes of carbonate surfaces from SmartWater (diluted seawater)-flooding processes for improved oil recovery.

Langmuir 2018 Dec 3. Epub 2018 Dec 3.

Over the past few decades, field and laboratory scale studies have shown enhancements in oil recovery when reservoirs, which contain high-salinity formation water (FW), are waterflooded with modified-salinity salt water (widely referred to as the "low-salinity", "dilution", or "SmartWater" effect for improved oil recovery). In this study, we investigated the time-dependence of the physico-chemical processes that occur during diluted seawater ( i.e. Read More

Beyond interferon side effects: What residual barriers exist to DAA hepatitis C treatment for people who inject drugs?

PLoS One 2018 30;13(11):e0207226. Epub 2018 Nov 30.

Centre for Social Research in Health, UNSW Sydney, Sydney, Australia.

Recent advances in the efficacy and tolerability of hepatitis C treatments and the introduction of a universal access scheme for the new Direct Acting Antiviral (DAA) therapies in March 2016, has resulted in a rapid increase in the uptake of hepatitis C treatment in Australia. Despite these positive developments, recent data suggest a plateauing of treatment numbers, indicating that more work may need to be done to identify and address ongoing barriers to hepatitis C treatment access and uptake. This paper aims to contribute to our understanding of the ongoing barriers to DAA therapies, with a focus on people who inject drugs. Read More

Preventing murine transfusion-related acute lung injury by expansion of CD4 CD25 FoxP3 Tregs using IL-2/anti-IL-2 complexes.

Transfusion 2018 Nov 30. Epub 2018 Nov 30.

Institute of Blood Transfusion, Chinese Academy of Medical Sciences, Chengdu, China.

Background: Transfusion-related acute lung injury (TRALI) is one of the most serious adverse events following transfusion, and there is no specific treatment in clinical practice. However, regulatory T cells (Tregs) have been suggested to play a potential role in the treatment of TRALI. This study investigated whether interleukin (IL)-2 or IL-2/anti-IL-2 complexes (IL-2c), which are mediators of Treg expansion, can modulate the severity of antibody-mediated TRALI in vivo. Read More

[Reparative mechanisms in retina and hypothalamus contributing to rhodopsin recovery in rabbit eyes with retinal dystrophy].

Vestn Oftalmol 2018 ;134(5):39-47

Institute of Physiology named after A.I. Karayev, 2 Sharifzadeh St., Baku, Republic of Azerbaijan, AZ1100.

Purpose: To study the molecular reparatory mechanisms of the retina and hypothalamus in the context of experimental dystrophy of receptor apparatus in rabbit retina.

Material And Methods: Retinal dystrophy was induced in rabbit eyes by injecting monoiodacetic acid (MIA) intravenously. Indirect ELISA test was used to evaluate the levels of rhodopsin, heat shock protein 70 kDa (HSP70) in the retina, and serotonin-modulating anticonsolidation protein (SMAP) - that directly correlates with serotonin level - in the hypothalamus.

Chilo iridescent virus encodes two functional metalloproteases.

Arch Virol 2018 Nov 29. Epub 2018 Nov 29.

Department of Biology, Faculty of Science, Karadeniz Technical University, 61080, Trabzon, Turkey.

The genome of Chilo iridescent virus (CIV) has two open reading frames (ORFs) with matrix metalloprotease (MMP) domains. The protein encoded by ORF 136R contains 178 amino acids with over 40% amino acid sequence identity to hypothetical metalloproteases of other viruses, and the protein 165R contains 264 amino acids with over 40% amino acid sequence identity to metalloproteases of a large group of organisms, primarily including a variety of Drosophila species. These proteins possess conserved zinc-binding motifs in their catalytic domains. Read More

A Structural Homology Approach for Computational Protein Design with Flexible Backbone.

Bioinformatics 2018 Nov 29. Epub 2018 Nov 29.

LISBP, Université de Toulouse, CNRS, INRA, INSA, Toulouse, France.

Motivation: Structure-based Computational Protein design (CPD) plays a critical role in advancing the field of protein engineering. Using an all-atom energy function, CPD tries to identify amino acid sequences that fold into a target structure and ultimately perform a desired function. Energy functions remain however imperfect and injecting relevant information from known structures in the design process should lead to improved designs. Read More
