Application of Electron Microscopes in Nanotoxicity Assessment.

Methods Mol Biol 2019 ;1894:247-269

Department of Anatomical Sciences and Neurobiology, University of Louisville, Louisville, KY, USA.

In this chapter, we highlight the applications of electron microscopes (EMs) in nanotoxicity assessment. EMs can provide detailed information about the size and morphology of nanomaterials (NMs), their localization in cells and tissues, the nano-bio interactions, as well as the ultrastructural changes induced by NMs exposure. Here, we share with the readers how we prepare the tissue sample, and the different types of EMs used among the nanotoxicologists. Read More

The impacts of laser zona thinning on hatching and implantation of vitrified-warmed mouse embryos.

Lasers Med Sci 2018 Dec 13. Epub 2018 Dec 13.

National Engineering Laboratory for Animal Breeding and Key Laboratory of Animal Genetics, Breeding and Reproduction, Beijing Key Laboratory for Animal Genetic Improvement, College of Animal Science and Technology, China Agricultural University, Beijing, China.

Embryo vitrification has advantages in assisted reproduction yet it also induces zona hardening. Laser zona thinning (LZT) is considered as a solution yet its efficacy and security have not been well studied. In this study, we used vitrified-warmed morulae from 2-month-old and 10-month-old ICR female mice as model to investigate the impacts that LZT treatment brings to the in vitro hatching process and implantation by analyzing hatching rate, implantation rate, and blastocyst quality.

Jacobian-Based Task-Space Motion Planning for MRI-Actuated Continuum Robots.

IEEE Robot Autom Lett 2019 Jan 19;4(1):145-152. Epub 2018 Nov 19.

Department of Electrical Engineering and Computer Science, Case Western Reserve University, Cleveland, OH.

Robot-assisted medical interventions, such as robotic catheter ablation, often require the robot to perform tasks on a tissue surface. This paper presents a task-space motion planning method that generates actuation trajectories which steer the end- effector of the MRI-actuated robot along desired trajectories on the surface. The continuum robot is modeled using the pseudo-rigid-body model, where the continuum body of the robot is approximated by rigid links joined by flexible joints. Read More

New Insight into Sperm Capacitation: A Novel Mechanism of 17β-Estradiol Signalling.

Int J Mol Sci 2018 Dec 12;19(12). Epub 2018 Dec 12.

Laboratory of Reproductive Biology, Institute of Biotechnology CAS, v.v.i., BIOCEV, Prumyslova 595, 252 50 Vestec, Czech Republic.

17β-estradiol (estradiol) is a natural estrogen regulating reproduction including sperm and egg development, sperm maturation-called capacitation-and sperm⁻egg communication. High doses can increase germ cell apoptosis and decrease sperm count. Our aim was to answer the biological relevance of estradiol in sperm capacitation and its effect on motility and acrosome reaction to quantify its interaction with estrogen receptors and propose a model of estradiol action during capacitation using kinetic analysis.

Applied Stress-Assisted Growth of Single Crystal γ-Fe₂O₃ Nanowires.

Nanomaterials (Basel) 2018 Dec 12;8(12). Epub 2018 Dec 12.

Bejing Key Laboratory of Quantum Devices, Key Laboratory for the Physics and Chemistry of Nanodevices, and Department of Electronics, Peking University, Beijing 100871, China.

It is difficult to obtain γ-Fe₂O₃ nanostructures by heating iron substrate in ambient conditions because γ-Fe₂O₃ is less thermodynamically stable than α-Fe₂O₃. In this work, we synthesize γ-Fe₂O₃ nanowires by heating iron particles under an external force. The stacking style of iron and oxygen ions under a strong shearing stress tends to adopt the γ-Fe₂O₃ structure regardless of the thermodynamic restriction. Read More

Shear-Assisted Laser Transfer of Metal Nanoparticle Ink to an Elastomer Substrate.

Materials (Basel) 2018 Dec 11;11(12). Epub 2018 Dec 11.

Optical Nanoprocessing Lab, Department of Mechanical Engineering, Hanyang University, 55 Hanyangdaehak-ro, Sangnok-gu, Ansan, Gyeonggi-do 15588, Korea.

Selective laser sintering of metal nanoparticle ink is an attractive technology for the creation of metal layers at the microscale without any vacuum deposition process, yet its application to elastomer substrates has remained a highly challenging task. To address this issue, we introduced the shear-assisted laser transfer of metal nanoparticle ink by utilizing the difference in thermal expansion coefficients between the elastomer and the target metal electrode. The laser was focused and scanned across the absorbing metal nanoparticle ink layer that was in conformal contact with the elastomer with a high thermal expansion coefficient. Read More

Objectives: Benzodiazepine (BZD) use is common in patients who are engaged in methadone as a treatment for opioid use disorder. BZD prescribing is generally discouraged for this patient population due to the increased risk of BZD dependence and BZD use disorder, medication-assisted treatment (MAT) discontinuation, and opioid-overdose death. However, some patients have concurrent mental health disorders, where BZD use may be clinically indicated. Read More

Topological boundaries and bulk wavefunctions in the Su-Schreiffer-Heeger model.

J Phys Condens Matter 2018 Dec 13;31(4):045001. Epub 2018 Dec 13.

Working in the context of the Su-Schreiffer-Heeger model, the effect of topological boundaries on the structure and properties of bulk position-space wavefunctions is studied for a particle undergoing a quantum walk in a one-dimensional lattice. In particular, we consider what happens when the wavefunction reaches a boundary at which the Hamiltonian changes suddenly from one topological phase to another and construct an exact solution for the wavefunction on both sides of the boundary. The reflection and transmission coefficients at the boundary are calculated as a function of the system's hopping parameters, and it is shown that for some parameter ranges the transmission coefficient can be made very small.

Mononuclear Salen-Sodium Ion Pairs as Catalysts for Isoselective Polymerization of rac-Lactide.

Inorg Chem 2018 Dec 13. Epub 2018 Dec 13.

State Key Laboratory of Applied Organic Chemistry, College of Chemistry and Chemical Engineering, Key Laboratory of Nonferrous Metal Chemistry and Resources Utilization of Gansu Province , Lanzhou University , Lanzhou 730000 , People's Republic of China.

A series of mononuclear salen-sodium anions, as the first examples, were synthesized with tetra-alkyl ammonium as a counterpart cation. These complexes are efficient catalysts for the isoselective ring-opening polymerization of rac-lactide; the molecular weights of polymers are under control and molecular weight distributions are narrow when five equivalents of BnOH is used as an initiator. The best isoselectivity value of P = 0. Read More

Transition-metal-catalyzed site-selective C7-functionalization of indoles: advancement and future prospects.

Chem Commun (Camb) 2018 Dec 13. Epub 2018 Dec 13.

Department of Chemistry, Indian Institute of Technology Guwahati, Guwahati 781039, India.

C7-Decorated indoles are important structural motifs present in a plethora of bioactive and pharmaceutical compounds. Early stage developments for C7 modifications were realized through directed metallation (DOM) and subsequent quenching with suitable electrophiles or by halogenation with Cu(ii) halides. Direct C-7 functionalization of indoles is comparatively difficult compared to functionalization at C-2 and C-3 positions owing to the inherent reactivity of the pyrrole-type ring. Read More

Evaluation of the performance of MALDI-TOF MS and DNA sequence analysis in the identification of mycobacteria species

Turk J Med Sci 2018 12 12;48(6):1351-1357. Epub 2018 Dec 12.

Department of Medical Microbiology, School of Medicine, Acıbadem University, İstanbul, Turkey

Background/aim: Matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometry is an alternative way of identifying mycobacteria via the analysis of biomolecules. It is being increasingly used in routine microbiology practice since it permits early, rapid, and cost-effective identification of pathogens of clinical importance. In this study, we aimed to evaluate the efficacy of phenotypic identification of mycobacteria by the MALDI-TOF MS MBT Mycobacteria Library (ML) 4. Read More
