The use of 'ice' flavoured e-cigarettes may be common and positively associated with conventional smoking and nicotine dependence among young adults, suggests research published online in the journal Tobacco Control.
And it's unclear where these' hybrid' vapes, combining fruit/sweet and cooling flavours, fit into current or future regulatory frameworks, which apply restrictions according to distinct flavour categories, point out the study authors.
Reston, VA (Embargoed until 7:30 p.m. EDT, Monday, June 14, 2021)--A protein that is critical in cancer cell metabolism has been imaged for the first time with a newly developed radiopharmaceutical, 18F-DASA-23. Imaging with this novel agent has the potential to improve the assessment of treatment response for patients, specifically those with brain tumors. This study was presented at the Society of Nuclear Medicine and Molecular Imaging 2021 Annual Meeting.
Reston, VA (Embargoed until 7:30 p.m. EDT, Monday, June 14, 2021)--In patients with mild cognitive impairment, taking lipophilic statins more than doubles their risk of developing dementia compared to those who do not take statins. According to research presented at the Society of Nuclear Medicine and Molecular Imaging 2021 Annual Meeting, positron emission tomography (PET) scans of lipophilic statin users revealed a highly significant decline in metabolism in the area of the brain that is first impacted by Alzheimer's disease.
When Erin Hecht was earning her Ph.D. in neuroscience more than a decade ago, she watched a nature special on the Russian farm-fox experiment, one of the best-known studies on animal domestication.
Like amyloid plaque, the genetic variant APOE4 has long been associated with Alzheimer's disease, but still little is known about the role the gene plays in the disease process.
Osaka, Japan - Researchers from the Graduate School of Engineering and the Center for Quantum Information and Quantum Biology at Osaka University unveiled a new solid state second-harmonic generation (SHG) device that converts infrared radiation into blue light. This work may lead to a practical daily-use deep ultraviolet light source for sterilization and disinfection.
Singapore, 14 June 2021 - Many butterfly species bear distinct circular markings known as eyespots on their wings, and the functions of these rings of contrasting colours vary. A long-standing theory is that they serve as anti-predator defences - small eyespots along the wing margin can protect butterflies by directing predators to attack less important parts of the body, such as the hindwings, enabling them to escape.
A team of scientists has shown that the healing of skin blisters is driven by hair follicle stem cells, which delay their own development in the process.
The healing process of the tissues in the human body is particularly well-studied in skin, especially as skin serves as a layer of protection from the environment. However, there remain some specific types of skin injuries where the healing process is not well understood.
Nearly 12,000 people in Sweden received sickness benefit from the Swedish Social Insurance Agency for COVID-19 during the first wave of the pandemic. The median duration of sick leave in this group was 35 days, but for many it was considerably more long-drawn-out, according to a University of Gothenburg study.
A research group in rehabilitation medicine at the University of Gothenburg has studied sick-leave patterns. The study now presented in the scientific journal BMC Public Health.
High running capacity is associated with health and longevity. However, whether high genetic running capacity promotes more efficient metabolism with aging is not known. A new study conducted in collaboration between the universities of Shanghai Jiao Tong University (China) and Jyväskylä (Finland) investigated the effects of genetic running capacity and aging on tissue metabolism. The study reveals that adipose tissue may have a key role in healthy aging.
Universal school lunch programs make students healthier, and increase their lifetime income by 3%, according to a unique study from Lund University in Sweden published in The Review of Economic Studies.
Announcing a new article publication for BIO Integration journal. In this article the authors Yuhao Chen, Yue Li, Meng Du, Jinsui Yu, Fei Gao, Zhen Yuan and Zhiyi Chen from The Third Affiliated Hospital of Guangzhou Medical University, Guangzhou, China, University of South China, Hunan, China and University of Macau, China discuss ultrasound neuromodulation: integrating medicine and engineering for neurological disease treatment.
Various platforms which offer food home delivery services through courier services, such as riders or other types of distributors, have proliferated very quickly in recent years, especially in big cities. Due to this boom in last-mile delivery or logistics, UOC experts have studied the operation of the main food home delivery platforms, such as Just Eat, Glovo and Deliveroo, which work in the city of Barcelona, to analyse the profitability of these business models and estimate the number of orders needed to achieve this profitability.
Near-field light is invisible light at the subwavelength scale. Harnessed for a variety of practical applications, such as wireless power transfer, near-field light has an increasingly significant role in the development of miniature on-chip photonic devices. Controlling the direction of near-field light propagation has been an ongoing challenge that is of fundamental interest in photonics physics and can significantly advance a variety of applications.
The human gut microbiome is a complex community of trillions of microbes that are constantly interacting with each other and our bodies. It supports our wellbeing, immune system and mental health - but how is it sustained?
Researchers in the UK and Germany, alongside other international collaborators, have investigated the evolution of bacteria in the human gut microbiome - asking how these microbes persist throughout their lifetimes - taking into account internal and external influencing factors.
