Biosynthetic Oligoclonal Antivenom (BOA) for Snakebite and Next-Generation Treatments for Snakebite Victims.

Toxins (Basel) 2018 Dec 13;10(12). Epub 2018 Dec 13.

Department of Biotechnology and Biomedicine, Technical University of Denmark, DK-2800 Kongens Lyngby, Denmark.

Snakebite envenoming is a neglected tropical disease that each year claims the lives of 80,000⁻140,000 victims worldwide. The only effective treatment against envenoming involves intravenous administration of antivenoms that comprise antibodies that have been isolated from the plasma of immunized animals, typically horses. The drawbacks of such conventional horse-derived antivenoms include their propensity for causing allergenic adverse reactions due to their heterologous and foreign nature, an inability to effectively neutralize toxins in distal tissue, a low content of toxin-neutralizing antibodies, and a complex manufacturing process that is dependent on husbandry and procurement of snake venoms.

Endotracheal intubation results in acute tracheal damage induced by mtDNA/TLR9/NF-κB activity.

J Leukoc Biol 2018 Dec 13. Epub 2018 Dec 13.

Surgery, Washington University School of Medicine in Saint Louis, St. Louis, Missouri, USA.

Tracheitis secondary to placement of an endotracheal tube (ETT) is characterized by neutrophil accumulation in the tracheal lumen, which is generally associated with epithelial damage. Mitochondrial DNA (mtDNA), has been implicated in systemic inflammation and organ dysfunction following trauma; however, less is known about the effects of a foreign body on local trauma and tissue damage. We hypothesized that tracheal damage secondary to the ETT will result in local release of mtDNA at sufficient levels to induce TLR9 and NF-κB activation. Read More

Methods Mol Biol 2019 ;1894:1-29

Department of Chemical and Materials Engineering, University of Kentucky, Lexington, KY, USA.

As a consequence of their increase in annual production and widespread distribution in the environment, nanoparticles potentially pose a significant public health risk. The sought-after catalytic activity granted by their physiochemical properties doubles as a hazard to physiological processes following exposure through inhalation, oral, transdermal, subcutaneous, and intravenous uptake. Upon uptake into the body, their size, morphology, surface charge, coating, and chemical composition augment the response of biological systems to the materials and enhance their toxicity. Read More

Fully bioresorbable vascular scaffolds: lessons learned and future directions.

Nat Rev Cardiol 2018 Dec 13. Epub 2018 Dec 13.

CVPath Institute, Gaithersburg, MD, USA.

Fully bioresorbable scaffolds (BRS) were designed to overcome the limitations of metallic drug-eluting stents, which permanently cage the vessel wall, thereby preventing normal coronary vasomotion, preclude bypass grafting and can provoke long-term foreign-body responses. Although multiple scaffolds have been or are in development, the Absorb Bioresorbable Vascular Scaffold (BVS; Abbott Vascular) was the first FDA-approved device and was widely expected to fulfil the dream of interventional cardiologists of a transient scaffold that would disappear 'when the job was done' and would not hamper further treatment options. Although early, small studies and even large, randomized trials showed beneficial outcomes up to 1 year of follow-up, longer-term results have been disappointing, with increased rates of device thrombosis and target-lesion revascularization.

Emergency University Hospital, Bucharest, Romania, "Carol Davila" University of Medicine and Pharmacy, 050474 Bucharest, Romania.

Pathologies of the brain, of which brain cancer, Alzheimer's disease, Parkinson's disease, stroke, and multiple sclerosis, are some of the most prevalent, and that presently are poorly treated due to the difficulties associated with drug development, administration, and targeting to the brain. The existence of the blood-brain barrier, a selective permeability system which acts as a local gateway against circulating foreign substances, represents the key challenge for the delivery of therapeutic agents to the brain. However, the development of nanotechnology-based approaches for brain delivery, such as nanoparticles, liposomes, dendrimers, micelles, and carbon nanotubes, might be the solution for improved brain therapies.

Enhancing charge transfer with foreign molecules through femtosecond laser induced MoS defect sites for photoluminescence control and SERS enhancement.

Nanoscale 2018 Dec 13. Epub 2018 Dec 13.

Department of Electrical and Computer Engineering, University of Nebraska-Lincoln, Lincoln, NE 68588-0511, USA.

Defect/active site control is crucial for tuning the chemical, optical, and electronic properties of MoS2, which can adjust the performance of MoS2 in application areas such as electronics, optics, catalysis, and molecular sensing. This study presents an effective method of inducing defect/active sites, including micro/nanofractured structures and S atomic vacancies, on monolayer MoS2 flakes by using femtosecond laser pulses, through which physical-chemical adsorption and charge transfer between foreign molecules (O2 or R6G molecules) and MoS2 are enhanced. The enhanced charge transfer between foreign molecules (O2 or R6G) and femtosecond laser-treated MoS2 can enhance the electronic doping effect between them, hence resulting in a photoluminescence photon energy shift (reaching 0.

Pollen Tube Pathway-Mediated Cotton Transformation.

Methods Mol Biol 2019 ;1902:67-73

Henan Collaborative Innovation Center of Modern Biological Breeding, Henan Institute of Sciences and Technology, Xinxiang, Henan, China.

Although many gene transfer methods have been employed for successfully obtaining transgenic cotton, the major constraint in cotton improvement is the limitation of genotype because the majority of transgenic methods require plant regeneration from a single transformed cell which is limited by cotton tissue culture. Comparing with other plant species, it is difficult to induce plant regeneration from cotton; currently, only a limited number of cotton cultivars can be cultured for obtaining regenerated plants. Thus, developing a simple and genotype-independent genetic transformation method is particularly interested for cotton. Read More

Therapeutic strategies based on in vitro-transcribed mRNA (IVT) are attractive because they avoid the permanent signature of genomic integration that is associated with DNA-based therapy and result in the transient production of proteins of interest. To date, IVT has mainly been used in vaccination protocols to generate immune responses to foreign Ags. In this "proof-of-principle" study, we explore a strategy of combinatorial IVT to recruit and reprogram immune effector cells to acquire divergent biological functions in mice in vivo. Read More

MHC proteins that present peptide ligands for recognition by TCR form nanoscale clusters on the cell membrane of APCs. How the extent of MHC clustering controls productive TCR engagement and TCR-mediated signaling has not been systematically studied. To evaluate the role of MHC clustering, we exploited nanoscale discoidal membrane mimetics (nanolipoprotein particles) to capture and present peptide-MHC (pMHC) ligands at various densities.

Development of stable rotavirus reporter expression systems.

J Virol 2018 Dec 12. Epub 2018 Dec 12.

Department of Virology, Research Institute for Microbial Diseases, Osaka University, Osaka, Japan

Engineered recombinant viruses expressing reporter genes have been developed for real-time monitoring of replication and for mass screening of anti-viral inhibitors. Recently, we reported using a reverse genetics system to develop the first recombinant reporter rotaviruses (RVs) that expressed NanoLuc (NLuc) luciferase. Here, we describe a strategy for developing stable reporter RVs expressing luciferase and green or red fluorescent proteins. Read More

The pathogenesis of foot-and-mouth disease virus (FMDV) in cattle was investigated through early and late stages of infection by use of an optimized experimental model for controlled contact exposure. Time-limited exposure of cattle to FMDV-infected pigs led to primary FMDV infection of the nasopharyngeal mucosa in both vaccinated and nonvaccinated cattle. In nonvaccinated cattle, the infection generalized rapidly to cause clinical disease, without apparent virus amplification in the lungs prior to establishment of viremia. Read More

Novel Surfaces in Extracorporeal Membrane Oxygenation Circuits.

Front Med (Lausanne) 2018 20;5:321. Epub 2018 Nov 20.

Department of Critical Care Medicine, The Hospital for Sick Children, University of Toronto, Toronto, ON, Canada.

The balance between systemic anticoagulation and clotting is challenging. In normal hemostasis, the endothelium regulates the balance between anticoagulant and prothrombotic systems. It becomes particularly more challenging to maintain this physiologic hemostasis when we are faced with extracorporeal life support therapies, where blood is continuously in contact with a foreign extracorporeal circuit surface predisposing a prothrombotic state.
