BACKGROUND: Implant stability testing at various stages of implant therapy by means of resonance frequency analysis is extensively used. The overall measurement outcome is a function of the resulting stiffness of three entities: surrounding bone, bone-implant complex, and implant-Smartpeg complex. The influence of the latter on the overall measurement results is presently unknown. It can be investigated in vitro by use of imbedded implants with mounted Smartpegs. This enables to keep the influence of the two other entities constant and controlled...

Modulations of epigenetic machinery, namely DNA methylation pattern, histone modification, and non-coding RNAs expression, have been recently included among the key determinants contributing to Parkinson's Disease (PD) aetiopathogenesis and response to therapy. Along this line of reasoning, a set of experimental findings are highlighting the epigenetic-based response to electromagnetic (EM) therapies used to alleviate PD symptomatology, mainly Deep Brain Stimulation (DBS) and Transcranial Magnetic Stimulation (TMS)...

Implantable cardioverter defibrillators (ICDs) have been shown to have a significant benefit in reducing sudden cardiac death (SCD) in patients with systolic heart failure. Additionally, cardiac devices as a bridge to transplant or destination therapy are often used in patients with end stage systolic heart failure. As a result most patients with left ventricular assist devices (LVADs) also have an ICD. Here we present an electromagnetic interference (EMI) between HeartMate 3 LVAD and ICD. This issue might be critical for both electrophysiologists and advanced heart failure cardiologists to understand prior to implantation of ICD/ LVADs in these patients...

Implantation of cardiac resynchronization therapy (CRT) devices can be challenging, time consuming, and associated with high-dose X-Ray exposure. We present the technique in which an electromagnetic navigation system (MediGuideTM, St. Jude Medical) and an electro-anatomical three-dimensional mapping system (EnSite NavX, St Jude Medical) are usefully combined for implanting ICD-CRT devices with strong reduction of X-ray exposure, and for targeting the most delayed regions in the activation maps avoiding scars for optimal CRT response...

PURPOSE OF REVIEW: Patients with cardiac implantable electronic devices (CIEDs) frequently undergo various surgical procedures and in the past perioperative management involved only placing magnet over the device. New programming features, development of implantable cardiac defibrillator (ICD), cardiac resynchronization therapy, and increasing complexity of the operating room equipment have led to new sources of electromagnetic interference (EMI). A comprehensive understanding of the CIED is necessary to provide a timely and optimal care to the patients...

INTRODUCTION: Osteonecrosis is an ischemic pathologic process associated with a number of conditions affecting a range of age groups. The problem faced in the management of osteonecrosis is whether conservative treatment is a viable and effective option for patients. In this systematic review, we investigated the efficacy of various nonoperative treatment modalities for hip and knee osteonecrosis, including pharmacological management and biophysical modalities. METHODS: We identified 16 studies based on electronic searches through the PubMed, Embase, CINAHL Plus, and Cochrane databases from January 2001 to November 2015...

Superparamagnetic iron oxide nanoparticles (SPION) may be used for local tumor treatment by coupling them to a drug and accumulating them locally with magnetic field traps, that is, a combination of permanent magnets and coils. Thereafter, an alternating magnetic field generates heat which may be used to release the thermosensitively bound drug and for hyperthermia. Until today, only superficial tumors can be treated with this method. Our aim was to transfer this method into an endoscopic setting to also reach the majority of tumors located inside the body...

Here we report a composite system based on fibrin hydrogels that incorporate in their structure near-infrared (NIR) responsive nanomaterials and thermosensitive liposomes (TSL). Polymerized fibrin networks entrap simultaneously gold-based nanoparticles (NPs) capable of transducing NIR photon energy into heat, and lysolipid-incorporated TSL (LTSL) loaded with doxorubicin hydrochloride (DOX). NIR irradiation of the resulting hydrogels (referred to as "lipogels") with 808nm laser light increased the temperature of the illuminated areas, leading to the release of the liposomal cargo...

In the rewarming process during cryopreservation, preventing ice recrystallization and thermal stress is important, especially for large tissues and organs. Uniform and rapid heating is essential in ameliorating the problem and maintaining the viability of cryopreserved biological samples. Currently, the most promising method is heating by application of electromagnetic (EM) waves, the effectiveness of which is dependent on the dielectric properties (DP) of the cryopreserved materials. In this work, the cavity perturbation method was adopted to measure the DP of cryoprotectant solutions...

BACKGROUND: Some patients with chronic abdominal pain suffer from an anterior cutaneous nerve entrapment syndrome (ACNES). This somewhat illusive syndrome is thought to be caused by the entrapment of end branches of the intercostal nerves residing in the abdominal wall. If ACNES is suspected, a local injection of an anesthetic agent may offer relief. If pain is recurrent following multiple-injection therapy, an anterior neurectomy entailing removal of the entrapped nerve endings may be considered...
