boron/dental caries

Boron neutron capture therapy (BNCT) without craniotomy for malignant brain tumours was started using an epi-thermal neutron beam at the Kyoto University Reactor in June 2002. We have tried some techniques to overcome the treatable-depth limit in BNCT. One of the effective techniques is void

Drinking water of rats aged 21 days was supplemented with 1, 10, 30, 50, 100, or 283 ppm of boron or 10 or 25 ppm of fluoride individually or in combination. All rats were fed a cariogenic diet. Boron did not reduce dental caries activity in erupted molars after eight weeks. When given in

Hexagonal boron nitride (hBN) is an emerging layered material that plays a key role in a variety of two-dimensional devices, and has potential applications in nanophotonics and nanomechanics. Here, we demonstrate the first cavity optomechanical system incorporating hBN. Nanomechanical resonators

BACKGROUND The purpose of the present study is to verify the treatment effects of boron neutron capture therapy (BNCT) in ectopic tumors implanted in the thoracic cavity mimicking malignant pleural mesothelioma (MPM). METHODS The tumor model was created by implanting murine squamous cell carcinoma

Quantum photonics technologies require a scalable approach for the integration of non-classical light sources with photonic resonators to achieve strong light confinement and enhancement of quantum light emission. Point defects from hexagonal Boron Nitride (hBN) are amongst the front runners for

Development of scalable quantum photonic technologies requires on-chip integration of photonic components. Recently, hexagonal boron nitride (hBN) has emerged as a promising platform, following reports of hyperbolic phonon-polaritons and optically stable, ultra-bright quantum emitters. However,

The purpose of this clinical trial was to evaluate the utility of boron neutron capture therapy (BNCT) using epithermal neutrons for cases of recurrent cancer in the oral cavity, which are not indicated for a conventional treatment modality. We enrolled four patients with local recurrence or

The aim of the present study was to find out the effects of boron on ostrich chicks fed with 0 mg/l, 100 mg/l, 200 mg/l, and 400 mg/l of additional boron in water. We measured bone mineral density (BMD), perimeter, length, weight, ash content of ostrich tibias, thickness of cortical bone, and

We present a comprehensive analysis of chemical bonding in pure boron clusters. It is now established in joint experimental and theoretical studies that pure boron clusters are planar or quasi-planar at least up to twenty atoms. Their planarity or quasi-planarity was usually discussed in terms of

The pristine boron nitride nanotube (BNNT) exhibits a poor chemical reactivity to some adsorbates, thus greatly limiting its application for the gas sensor. In the present work, using density functional theory (DFT) methods, we put forward a novel strategy to enhance the sensitivity of BNNT to

To improve beam penetration into a head allowing the treatment of deeper seated tumors, two neutron collimators were built sequentially and tested for use in the clinical boron neutron capture therapy (BNCT) program at the epithermal neutron irradiation facility of the Brookhaven Medical Research

The bright and stable single-photon emission under room temperature conditions from color centers in hexagonal boron nitride (hBN) is considered as one of the most promising quantum light sources for quantum cryptography as well as spin-based qubits, similar to recent advances in nitrogen-vacancy
