From Light to Sound: Photoacoustic and Ultrasound Imaging in Fundamental Research of Alzheimer’s DiseaseAbstract
Alzheimer’s disease (AD) causes severe cognitive dysfunction and has long been studied for the underlining physiological and pathological mechanisms. Several biomedical imaging modalities have been applied, including MRI, PET, and high-resolution optical microscopy, for research purposes. However, there is still a strong need for imaging tools that can provide high spatiotemporal resolutions with relatively deep penetration to enhance our understanding of AD pathology and monitor treatment progress in fundamental r [...] 2545 15847 |
Mechano-Vibrational Spectroscopy of Tissues and Materials Using Vibrational Optical Coherence Tomography: A New Non-Invasive and Non-Destructive TechniqueAbstract
Elastic moduli of tissues and synthetic polymeric materials are important design properties needed to develop new implants. In this paper we report the use of vibrational optical coherence tomography (VOCT) to measure the resonant frequency and calculate the modulus of tissues and synthetic polymers non-invasively and non-destructively in vitro and in vivo. Values of tissue and polymer moduli were obtained by applying an audible sinusoidal sound wave to the surface of each specimen. The sound wave travels to the in [...] 3071 23923 |
New Horizons in Alzheimer Research from Amyloid and Beyondby
Abstract
The Amyloid and Tau Hypothesis of Alzheimer’s disease once thought to be the key have shown marginal results but are bolstered by the recent revival of the Aducanumab study and some positive data on some anti-Tau drugs. It still behoves us to look at other mechanisms which include whole blood transfusions, an Epigenetic approach, a-derivative of a Parkinson's drug a low dose of an anti-epileptic drug, an antibiotic against P Gingivitis and many new approaches not directly involving Amyloid and Tau. Other newer appr [...] 2128 69428 |
Storable Energy Production from Wind over WaterAbstract
The current status of a project is described which aims to demonstrate the technical and economic feasibility of converting the vast wind energy available over the globe’s oceans and lakes into storable energy. To this end, autonomous high-performance sailing ships are equipped with hydrokinetic turbines whose output is stored either in electric batteries or is fed into electrolysers to produce hydrogen which then is compressed and stored in tanks. In the present paper, the previous analytical studies which showed [...] 2023 10984 |
Autonomous Hydrogen Production for Proton Exchange Membrane Fuel Cells PEMFCby
Abstract
This paper focuses on hydrogen production for green mobility applications (other applications are currently under investigation). Firstly, a brief state of the art of hydrogen generation by hydrolysis with magnesium is shown. The hydrolysis performance of Magnesium powder ball–milled along with different additives (graphite and transition metals TM = Ni, Fe, and Al) is taken for comparison. The best performance was observed with Mg–10 wt.% g mixtures (95% of theoretical hydrogen generation yield in about 3 min). An [...] 2608 16956 |
Feeling Safe during Intensive Care: Protocol of a Pilot Study on Therapeutic Suggestions of Safety under Hypnosis in Patients with Non-Invasive VentilationAbstract
Patients in the intensive care unit are confronted with an extreme situation that may cause stress and anxiety. The negative experiences may cause patients to suffer for the long-term after leaving the intensive care unit. One such stressor in the intensive care unit is non-invasive ventilation. Positive therapeutic suggestions under hypnosis can help patients in intensive care to enhance their well-being by helping them to deal with specific stress like being ventilated. The aim of our study is to assess the effec [...] 2102 11042 |
Effectiveness of Aromatherapy in Alleviating Palliative Symptoms and Its Possible Side Effects: A Literature ReviewAbstract
Palliative care is a steadily growing component of medicine that focuses on treating individuals with life-limiting diseases such as cancer. It aims at improving the quality of life and alleviating cancer-related symptoms, including anxiety, pain, dyspnea, cough, nausea/vomiting, and constipation, which could result in significant physical and mental impairment. Integrative palliative care (IPC), as a subspecialty of palliative care, includes complementary approaches to treat patients holistically in their biopsych [...] 2935 18420 |
Professionals’ Views on Offering Pre-Natal Testing for Adult Onset Cancer Susceptibility. Reconciling Personal and Professional Ethical Conflicts, Coping Strategies and Need for Policy Transparencyby
Abstract
This paper explores views of healthcare professionals (HCPs) in genetics and foetal medicine settings on offering pre-natal diagnosis (PND) for adult onset cancer susceptibility (AOCS) genes. Study participants came from different disciplinary backgrounds and all had considered implications of offering PND for AOCS, directly or indirectly, from professional and personal perspectives. Foetal medicine and genetics teams are accustomed to offering PND with the possibility of terminating an affected foetus on the basis [...] 2050 10675 |
Neural Mechanisms of Hypnotic AnalgesiaAbstract
There is increasing evidence demonstrating that hypnosis could be effective in the down-modulation of pain sensation in both acute and chronic pain states. In the neurophysiological context, recent evidence has deciphered, to a certain extent, the mystery of pain relief upon hypnosis. It is probable that hypnotic suggestions of analgesia are able to modulate pain processing at multiple levels and sites within the central nervous system (CNS). At the peripheral level, hypnosis may modulate the nociceptive input thro [...] 2067 16453 |
Can HCV Viremic Organs Be Used in Liver Transplantation to HCV Negative Recipients?by
Abstract
Liver transplantation has steadily increased worldwide resulting in a large number of patients on the waiting list. Due to the opioid epidemic in the US, the pool of Hepatitis C seropositive donors increased significantly in recent years. Direct acting antivirals played an instrumental role in making liver transplantation with hepatitis C positive allograft an acceptable option. Although hepatitis C positive liver transplantation to hepatitis C positive recipients is a common practice, there is limited data and agr [...] 1464 7517 |
