Autoimmune autonomic ganglionopathy (AAG) is an immune-mediated disorder that leads to various autonomic failures associated with anti-ganglionic acetylcholine receptor antibodies (anti-gAChR-Abs). Diffuse esophageal spasm (DES) is an uncommon esophageal motility disorder. We herein report the case of a 68-year-old woman with DES as a partial symptom of AAG. She presented with chronic esophageal transit failure, constipation, and numbness of the hands and feet, Adie's pupil, thermal hypoalgesia, and decreased deep tendon reflexes...

1 ESGE recommends cold snare polypectomy (CSP) as the preferred technique for removal of diminutive polyps (size ≤ 5 mm). This technique has high rates of complete resection, adequate tissue sampling for histology, and low complication rates. (High quality evidence, strong recommendation.) 2 ESGE suggests CSP for sessile polyps 6 - 9 mm in size because of its superior safety profile, although evidence comparing efficacy with hot snare polypectomy (HSP) is lacking. (Moderate quality evidence, weak recommendation...

Boron Neutron Capture Therapy (BNCT) is a radiation science which is emerging as a hopeful tool in treating cancer, by selectively concentrating boron compounds in tumour cells and then subjecting the tumour cells to epithermal neutron beam radiation. BNCT bestows upon the nuclear reaction that occurs when Boron-10, a stable isotope, is irradiated with low-energy thermal neutrons to yield α particles (Helium-4) and recoiling lithium-7 nuclei. A large number of 10 Boron (10B) atoms have to be localized on or within neoplastic cells for BNCT to be effective, and an adequate number of thermal neutrons have to be absorbed by the 10B atoms to maintain a lethal 10B (n, α) lithium-7 reaction...

PURPOSE: Boron neutron capture therapy (BNCT) is a binary treatment modality that uses high LET particles to achieve tumor cell killing. Deuterium-deuterium (DD) compact neutron generators have advantages over nuclear reactors and large accelerators as the BNCT neutron source, such as their compact size, low cost, and relatively easy installation. The purpose of this study is to design a beam shaping assembly (BSA) for a DD neutron generator and assess the potential of a DD-based BNCT system using Monte Carlo (MC) simulations...

Gene therapy provides an alternative and effective method for treatment of genetic diseases and cancers that are refractory to conventional therapeutics. The success of gene therapy is largely dependent on the development of safe and effective gene delivery vectors for transporting genetic material from the blood stream to the cytoplasm or nucleus. Current gene vectors can be divided into viral and non-viral vectors. Although non-viral gene delivery carriers can offer some advantages, such as safety and facile fabrication, they do not possess the same high gene transfection efficiency as viral vectors due to a lack of functionality to overcome extra- and intracellular gene delivery obstacles...

The peripheral dose distribution is a growing concern for the improvement of new external radiation modalities. Secondary particles, especially photo-neutrons produced by the accelerator, irradiate the patient more than tens of centimeters away from the tumor volume. However the out-of-field dose is still not estimated accurately by the treatment planning softwares. This study demonstrates the possibility of using a specially designed CMOS sensor for fast and thermal neutron monitoring in radiotherapy. The 14 microns-thick sensitive layer and the integrated electronic chain of the CMOS are particularly suitable for real-time measurements in γ/n mixed fields...

OBJECTIVE Image guidance for spinal procedures is based on 3D-fluoroscopy or CT, which provide poor visualization of soft tissues, including the spinal cord. To overcome this limitation, the authors developed a method to register intraoperative MRI (iMRI) of the spine into a neuronavigation system, allowing excellent visualization of the spinal cord. This novel technique improved the accuracy in the deployment of laser interstitial thermal therapy probes for the treatment of metastatic spinal cord compression...

: The use of non-invasive radiofrequency (RF) energy to induce mild thermal and non-thermal effects in cancer tissue is under study as an adjuvant to chemo, radio or immuno therapy. This study examines cell specific sensitivities to RF exposure and the potential of nanoparticles to elevate heating rates or enhance biological effects. Increases in the heating rate of water in an RF field operating at 13.56 MHz (0.004-0.028 °C/s) were positively correlated with concentration of hybrid nanoparticles (1-10 mg/ml) consisting of water soluble malonodiserinolamide [60]fullerene (C60-ser) conjugated to the surface of mesoporous silica nanoparticles (SiO2-C60)...

The therapeutic effects of non-thermal plasma are expected in the medical fields, including hemostasis, vascularization, prevention of organ adhesion, and cell proliferation. Cancer is an internal enemy arising from normal tissue in the body. The prognosis of metastatic and recurrent cancers is still poor despite advances in medicine. To apply non-thermal plasma in cancer treatment is now on going. The mechanism of the proliferation-inhibitory effect of plasma is reactive nitrogen oxide species/reactive oxygen species production in cells...

Various gold nanoparticles have been explored in biomedical systems and proven to be promising in photothermal therapy and drug delivery. Among them, nanoshells were regarded as traditionally strong near infrared absorbers that have been widely used to generate photothermal effect for cancer therapy. However, the nanoshell is not photo-thermal stable and thus is not suitable for repeated irradiation. Here, we describe a novel discrete gold nanostructure by mimicking the continuous gold nanoshell-gold/mesoporous silica hybrid nanoparticle (GoMe)...
