Tin @ Tio2 Core–Shell Nanoparticles As Plasmon-Enhanced Photosensitizers: The Role Of Hot Electron Injection, Xiaohui Xu, Aveek Dutta, Jacob Khurgin, Alexander Wei, Vladimir M. Shalaev, Alexandra Boltasseva

Department of Chemistry Faculty Publications

Metal–semiconductor heterostructures have attracted a lot of attention due to their ability to enhance photovoltaic and photocatalytic processes via plasmonic effects. Thus far, most of the proposed heterostructures are designed with noble metals and the potential of alternative plasmonic materials, such as titanium nitride (TiN), is not yet well explored. In this work, TiN@TiO2 core–shell nanoparticles (NPs) are synthesized and proposed as plasmon-enhanced photosensitizers for efficient singlet oxygen generation, with the focus on the role of hot electron injection. Excitation of dilute TiN@TiO2 NP dispersions by a 700 nm femtosecond-pulsed laser effectively converts ground-state oxygen into singlet oxygen (1O2), driven …

AIMS: Psychotropic prescription rates continue to increase in the United States (USA). Few studies have investigated whether social-structural factors may play a role in psychotropic medication use independent of mental illness. Food insecurity is prevalent among people living with HIV in the USA and has been associated with poor mental health. We investigated whether food insecurity was associated with psychotropic medication use independent of the symptoms of depression and anxiety among women living with HIV in the USA. METHODS: We used cross-sectional data from the Women's Interagency HIV Study (WIHS), a nationwide cohort study. Food security (FS) was the primary …

The year 2020 has seen an unprecedented COVID-19 pandemic due to the outbreak of a novel strain of coronavirus in 180 countries. In a desperate effort to discover new drugs and vaccines for COVID-19, many scientists are working around the clock. Their valuable time and effort may benefit from computer-based mining of a large volume of health science literature that is a treasure trove of information. In this paper, we have developed a graph-based model using abstracts of 10,683 scientific articles to find key information on three topics: transmission, drug types, and genome research related to coronavirus. A subgraph is …

Diabetes Mellitus And Necrotizing Fasciitis – A Deadly Combination; Case Report, Alexandra Toma, Laura Mazilu, Andra Iulia Suceveanu, Florentina Gherghiceanu, Camelia Sandu, Cristina Bica, Liliana Florina Andronache, Ioana Paunica, Lavinia Alexandra Moroianu

Journal of Mind and Medical Sciences

Necrotizing fasciitis is a rapidly destructive affliction of soft tissues, with a mortality rate that may reach 73% of the cases. It is characterized by a progressive inflammation and extended necrosis of the subcutaneous tissue and the fascia. Necrotizing fasciitis was first described in 1848, and later in 1920 Meleney identified 20 patients in China in which the infection was presumably triggered by hemolytic streptococcus, linking pathological bacteria to the condition. In 1952, Wilson coined the term necrotizing fasciitis although without successfully identifying the specific pathological bacteria involved. In most cases, both risk and aggravating factors are present, the main …

Risk Factors, Predictive Markers And Prevention Strategies For Intrauterine Fetal Death. An Integrative Review, Roxana Bohiltea, Natalia Turcan, Christina M. Cavinder, Ionită Ducu, Ioana Paunica, Liliana Florina Andronache, Monica Mihaela Cirstoiu

Journal of Mind and Medical Sciences

According to World Health Organization (WHO), fetal death is defined as the death of the fetus prior to its complete expulsion, independent of the duration of pregnancy, thus only ascribing the term stillbirth to fetal deaths in the case of pregnancies after 28 weeks of gestation. The great progress of perinatology care is reflected in a significant reduction in the rate of stillbirths, especially in well-developed countries, with approximately 98% of stillbirth cases now occurring in poor and developing countries. Stillbirth powerfully impacts both the patient and the practitioner. Because nearly half of stillbirth cases result from apparently uncomplicated pregnancies, …

Laser Therapy In Superficial Morphea Lesions – Indications, Limitations And Therapeutic Alternatives, Alin Laurentiu Tatu, Diana Sabina Radaschin, Vlad Denis Constantin, Paunica Stana, Valeriu Ardeleanu

Journal of Mind and Medical Sciences

Morphea or localized scleroderma is an uncommon autoimmune and inflammatory disease which affects patients of any age. Even if morphea lesions present systemic symptoms as myalgias or arthritis, it is distinct from systemic sclerosis because it does not associate Raynaud’s phenomena or sclerodactyly, which are encountered in systemic scleroderma. The most common form of morphea in children is `en coup de sabre`, which can alter the local anatomy by deep tissue involvement. In contrast, the most frequent form that affects adults is represented by circumscribed morphea. The initial lesions present an inflammatory phase that manifests in the form of erythematous …

Microbiota: The Missing Link In The Etiology Of Inflammatory Bowel Disease, Micu Ioan Sergiu, Madalina Elena Manea, Musat Marilena, Dumitru Andrada, Popoiag Roxana Emanuela

Journal of Mind and Medical Sciences

Within its twisted and tight walls, where a hostile and arid environment prevails, the lumen of the digestive tract nests a true microuniverse called the microbiota. The existing relationship between humans and these microorganisms is one in which both benefit, creating a condition called Eubiosis.

The dynamic relationship existing between the microbiota and the human body can be affected at various times, leading to an imbalance that may have important implications on health and generating a condition called Disbiosis.

Recent studies have highlighted possible links between several diseases with incompletely elucidated etiology and disturbances of the microbiota. In this review …

A Historical Review Of Management Options Used Against The Stable Fly (Diptera: Muscidae), David F. Cook

Animal production and livestock research articles

The stable fly, Stomoxys calcitrans (L.) (Diptera: Muscidae), remains a significant economic pest globally in situations where intensive animal production or horticultural production provide a suitable developmental medium. Stable flies have been recorded as pests of livestock and humans since the late 1800s to early 1900s. Over 100 years of research has seen numerous methodologies used to control this fly, in particular to protect cattle from flies to minimise production losses. Reduced milk production in dairy cows and decreased weight gain in beef cattle account for losses in the US alone of > $2000 million annually. Rural lifestyles and recreation are …

Novel Coronavirus (2019-Ncov) In Disguise, Qian Zhang, Annyella Douglas, Zain U. Abideen, Shristi Khanal, Stephanie Tzarnas

Abington Jefferson Health Papers

Novel coronavirus (2019-nCoV) pandemic is currently one of the most influential topics as it not only impacts the field of medicine but most importantly, it affects the lives of many individuals throughout the world. We report an interesting 2019-nCoV case in a tertiary community hospital with the initial concern of acute pyelonephritis without respiratory symptoms that ultimately led to the quarantine of a number of healthcare providers. This case emphasizes the importance of radiological evidence in diagnosing 2019-nCoV in the setting of an initial atypical presentation. It also serves as an example of how healthcare providers may need to increase …

Optimisation Of Vitamin D Status For Enhanced Immuno-Protection Against Covid-19, Daniel Mccartney, Declan G. Byrne

Articles

Abstract

Background

Vitamin D deficiency (serum 25(OH)D<50nmol/l) is common in Ireland, particularly amongst older adults, hospital inpatients and nursing home residents. Vitamin D deficiency is associated with increased risk of acute viral respiratory infection and community acquired pneumonia, with several molecular mechanisms proposed to explain this association. Vitamin D supplementation has also been shown to reduce the risk of respiratory infection.

Vitamin D and Covid-19

Correction of vitamin D deficiency is thought to suppress CD26, a putative adhesion molecule for Covid-19 host cell invasion. Vitamin D may also attenuate interferon gamma (IFNγ) and interleukin-6 (IL-6) inflammatory responses, both potent predictors of poorer outcome in critically-ill ventilated patients including those with Covid-19.

Vitamin D Requirements

Irish adults require 25-30μg/d of vitamin D3, an intake not achievable by diet alone, to reliably maintain serum 25(OH)D levels >50nmol/l. Supplementation with doses up to 100μg/d has been shown to be safe for adults, and many agencies and expert …

Zika And Dengue Virus Live Vaccines: Experiments To Improve The Thermostability Of A Vaccine Candidate Through Lyophilization, Marshall S. Butler

Library/Life Sciences Undergraduate Poster Competition 2020

With the recent outbreak of Zika virus in Central and South America, there has been an increased demand for vaccines around the world for both zika and dengue virus. Due to a combination of high environmental temperatures and poor cold-storage capabilities in developing countries, it is often difficult for a live-attenuated vaccine to be shipped and maintained. In order to preserve and stabilize vaccines at refrigerated temperatures so that they can be easily shipped and stored, lyophilization (freeze-drying) can be explored as a possible solution. A successful lyophilization process will ensure an extended product shelf life, improve virus stability, and …

Bibliometric Survey On Impact Of Sound Therapy On Blood Pressure And Covid-19., Vaishali Rajput, Preeti Mulay

Library Philosophy and Practice (e-journal)

The current situation of spread of Corona Virus is really worth to worry and critical. As we are moving from stage 2 to stage 3, it is really our duty and right to prevent its spread effectually, as its threat to life of every individual. As per the expert opinion from Health Organizations, the elder people are most at risk of Corona infection. But if the people with high blood pressure or high cholesterol fail to take their prescribed medication, then they are also prone to various infections, due to low immunity levels. Along with regular medication, Sound Therapy is …

Three-Dimensional Hydrodynamic Focusing For Integrated Optofluidic Detection Enhancement, Erik Scott Hamilton

Theses and Dissertations

The rise of superbugs, including antibiotic-resistant bacteria, and virus outbreaks, such as the recent coronavirus scare, illustrate the need for rapid detection of disease pathogens. Widespread availability of rapid disease identification would facilitate outbreak prevention and specific treatment. The ARROW biosensor microchip can directly detect single molecules through fluorescence-based optofluidic interrogation. The nature of the microfluidic channels found on optofluidic sensor platforms sets some of the ultimate sensitivity and accuracy limits and can result in false negative test results. Yet higher sensitivity and specificity is desired through hydrodynamic focusing. Novel 3D hydrodynamic focusing designs were developed and implemented on the …

Testing Tick Repellent Effectiveness​, Katherine Bunakov, Caleigh Carlson, Marianna Denully, Kyle Keenan, Doug Gourley, Jordan Rupley

2020 Symposium Posters

In the animal kingdom, the largest biodiversity is found in arthropods. Specific species include, crabs, ticks, and spiders. Interestingly, ticks are a species responsible for transmitting at least 14 known pathogens in the United States, as well as newly emerging tick-borne diseases. It is notable that the tick species found in Washington state do not carry as many diseases as ticks of other states, however, the likelihood of disease is still relevant. Protective clothing, repellents, and staying out of tick-prone areas are the best preventative measures to becoming indisposed. Furthermore, studying which repellents are most effective allows individuals to prevent …
