Endoscopic techniques are gaining popularity in the management of colorectal polyps and occasionally superficial cancers. While their use is in many times palliative, they have proven to be curative in carefully selected patients with polyps or malignancies, with less morbidity than radical resection. However, one should note that data supporting local and ablative therapies for colorectal canc...

The fatigue performance from pre-corroded pits was studied in laser-shock-peened AA7075-T651 with and without a protective ablation-layer. Surface microstructural characterisation showed laser-shock-peening generated residual stresses up to −400MPa, limited hardness moderate surface roughness increase. specimens were exposed 3.5 wt-% sodium chloride solution for different levels of galvanostati...

BACKGROUND The 2,790 nm Er:YSGG wavelength has a lower water absorption coefficient than the 2,940 nm Er:YAG, but a higher coefficient than the 10,600 nm CO(2) laser. This allows ablative resurfacing with mild thermal coagulation, which may increase clinical efficacy while reducing patient downtime. OBJECTIVES To evaluate the efficacy and safety of the confluent 2,790 nm Erbium:YSGG (Pearl™, ...

BACKGROUND High intensity-focused ultrasound (HIFU) is an alterative ablative technique currently being investigated for local treatment of breast cancer and fibroadenomas. Current HIFU therapies require concurrent magnetic resonance imaging monitoring. Biodegradable 500 nm perfluoropentane-filled iron-silica nanoshells have been synthesized as a sensitizing agent for HIFU therapies, which aid ...

OBJECTIVE To assess the clinical efficacy, safety, and risk factors influencing local tumor progression, following CT-guided radiofrequency ablation (RFA) of recurrent or residual hepatocellular carcinoma (HCC), around iodized oil retention. MATERIALS AND METHODS Sixty-four patients (M : F = 51 : 13, 65.0 ± 8.2 years old) with recurrent or residual HCC (75 index tumors, size = 14.0 ± 4.6 mm) ...

Radioiodine activity required for remnant thyroid ablation is of great concern, to avoid unnecessary exposure to radiation and minimize adverse effects. We investigated clinical outcomes of remnant thyroid ablation with a low radioiodine activity in Korean patients with low to intermediate-risk thyroid cancer. For remnant thyroid ablation, 176 patients received radioiodine of 1.1 GBq, under a s...

Human type 1 diabetes mellitus occurs due to chronic inflammation with lymphocytic infiltration and (usually) the presence of antibodies against insulin and characteristic islet cell proteins (e.g., GAD). This autoimmune process destroys the islets of Langerhans (including the beta cells) leading to insulin insufficiency. In several studies to date diabetes in the non-obese diabetic (NOD) mouse...
