In the pathogenesis of Alzheimer’s disease (AD) the homeostasis of amyloid precursor protein (APP) processing in the brain is impaired. The expression of the competing proteases ADAM10 (a disintegrin and metalloproteinase 10) and BACE-1 (beta site APP cleaving enzyme 1) is shifted in favor of the A-beta generating enzyme BACE-1. Acitretin–a synthetic retinoid–e.g., has been shown to increase ADAM10 gene expression, resulting in a decreased level of A-beta peptides within the brain of AD model mice and thus is of possible value for AD therapy. A striking challenge in evaluating novel therapeutically applicable drugs is the analysis of their potential to overcome the blood-brain barrier (BBB)…

Clinicians in 25 countries prefer to use lower levels of oxygen to resuscitate preterm infants at birth.

2016

Aim This study determined current international clinical practice and opinions regarding initial fractional inspired oxygen (FiO2) and pulse oximetry (SpO2) targets for delivery room resuscitation of preterm infants of less than 29 weeks of gestation. Methods An online survey was disseminated to neonatal clinicians via established professional clinical networks using a web-based survey programme between March 9 and June 30, 2015. Results Of the 630 responses from 25 countries, 60% were from neonatologists. The majority (77%) would target SpO2 between the 10th to 50th percentiles values for full-term infants. The median starting FiO2 was 0.3, with Japan using the highest (0.4) and the UK usi…

Efficient gene delivery to photoreceptors using AAV2/rh10 and rescue of the Rho–/– mouse

2015

As gene therapies for various forms of retinal degeneration progress toward human clinical trial, it will be essential to have a repertoire of safe and efficient vectors for gene delivery to the target cells. Recombinant adeno-associated virus (AAV) serotype 2/2 has been shown to be well tolerated in the human retina and has provided efficacy in human patients for some inherited retinal degenerations. In this study, the AAV2/8 and AAV2/rh10 serotypes have been compared as a means of gene delivery to mammalian photoreceptor cells using a photoreceptor specific promoter for transgene expression. Both AAV2/8 and AAV2/rh10 provided rescue of the retinal degeneration present in the rhodopsin kno…

New Directions for Use of Systemic Drug Delivery in Anti-aging Medicine

2020

Abstract Anti-aging medicine has become a popular topic in recent years. It considers biological aging a revertible process that physiologically serves no posi tive function. Different technologies in systemic delivery and various strategies that characterize and optimize the performance of systemic delivery have been covered in this book. These technologies are essential for the establishment of a technical platform for interventive biogerontology. As the last chapter of this book, we would like to highlight some directions for future applications of systemic drug delivery in anti-aging medicine. We believe that biological aging and aging-related diseases are strongly associated with genet…

Rapid, reproducible transduction of select forebrain regions by targeted recombinant virus injection into the neonatal mouse brain

2009

Viral vectors can mediate long-term gene expression in different regions of the brain. Recombinant adeno-associated virus (rAAV) and Lenti virus (LV) have both gained prominence due to their ability to achieve specific transduction of various neuronal populations. Whilst widespread gene delivery has been obtained by targeted injection of rAAV in various brain structures, LV has also been utilized for infection of stem cell populations for cell lineage tracing. Both viral vector systems are most commonly used for gene delivery in mature brains, but the great potential of somatic gene delivery into the neonate brain has not been systematically exploited. Here we provide a systematic guideline…

Open-Loop Drug Delivery Strategy to the Cochlea using a Permanent Magnetic Actuator

2018

International audience; The use of robotic devices for drug delivery in sensitive area of the human body is an innovative and reliable solution. Most of them use magnetics fields, to steer micro-nanorobots into diseases locations. In this study, we use a magnetic actuator based on two permanent magnets as an end-effector of a robotic manipulator. The actuator offers the possibility to generate both pushing and pulling forces on the magnetic actuator axis in an open-loop control way. We describe in this paper the robotic drug delivery strategy that we implemented in a 6 degree of freedom robotic manipulator to push and to steer a magnetic microparticle from the round window to the apex of th…

The pros and cons of the implementation of a chronic care model in European rural primary care: the points of view of European rural general practiti…

2021

Introduction: This article describes the views of European rural general practitioners regarding the strengths, weaknesses, opportunities and threats (SWOT) of the implementation of a chronic care model (CCM) in European rural primary care. Methods: This was a mixed-methods online survey. Data were collected from 227 general practitioners between May and December 2017. Categorical data were analysed using descriptive methods while free-text responses were analysed using qualitative methods. The setting was rural primary care in nine European countries (including Central and Eastern Europe). Main outcomes measures were respondents' evaluations of a chronic care model in their rural heal…

Realizing women´s right to maternal health: A study of awareness of rights and utilization of maternal health services among reproductive age women i…

2019

BackgroundMaternal mortality rates are still unacceptably high in many countries, indicating violation of women´s human right to life and health. Access to adequate information about maternal health rights and available services are essential aspects of realizing women´s right to accessible health care. This study aimed at assessing awareness of the right to access maternal health services among women who had recently given birth, and the association between such awareness and the utilization of maternal health services in two districts in Tanzania.MethodsThis study was cross sectional in design. Interviews were conducted with women who gave birth within one year prior to the survey in two …
