Peripheral neural interface (PNI) is becoming an essential technology in the field of robotic prosthesis due to its potential for providing bidirectional neural signal communication between the prosthetic arm and the brain. However, current PNIs inefficiently trade off neural signal selectivity and the invasiveness of the device. We designed and fabricated a new PNI electrode array that has high signal selectivity yet maintains low invasiveness by incorporating a design that allows for three-dimensional spiral insertion around the peripheral nerve...

BACKGROUND: Neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR), modified Glasgow prognostic score (mGPS) and prognostic nutritional index (PNI) are simple indices determined employing laboratory data alone and have been used to predict the clinical outcomes of patients with esophagogastric tumors. However, prior results were generally based on analyzing dichotomous data with arbitrary cutoff values. This retrospective study aims to assess prognostic utilities of preoperative NLR, PLR, LMR, mGPS and PNI, as continuous variables, in gastric cancer (GC) and adenocarcinoma of esophagogastric junction (AEG)...

In recent years, multiparametric magnetic resonance imaging (MRI) and MR/ultrasound (US) fusion targeted biopsy (TB) have become more widely adopted to aid in prostate cancer (PCa) detection. Previously, TB has been found to increase the yield of clinically significant PCa and is more likely to sample the index tumor compared to traditional 12-core extended sextant biopsies. Currently the prognostic significance of perineural invasion (PNI) when identified on TB (PNI-TB) is unknown. We identified 95 men at two tertiary referral centers who underwent TB followed by radical prostatectomy between January 2014 and January 2017...

PURPOSE: Atrial fibrillation (AF) is an arrhythmia which affects as many as 2.7 million Americans. AF should be treated, because it can lead to a four-to-fivefold increased risk of experiencing a stroke. The American College of Cardiology/American Heart Association guidelines for the treatment of drug refractory and symptomatic paroxysmal AF denote catheter ablation as the standard of care. The newest ablation treatment, cryoballoon, uses a cold balloon tip. The biggest risk factor associated with the cryoballoon ablation is phrenic nerve injury (PNI)...

The prognostic nutritional index (PNI) is a simple metric that uses serum albumin and total lymphocyte count to provide a basic indicator for nutritional status. It has recently garnered attention as a prognosticator of outcomes in many types of cancer. We investigated the utility of the PNI as a marker for poor outcomes following left ventricular assist device (LVAD) implantation. Two hundred eighty-eight consecutive patients implanted with continuous-flow LVADs were included. Prognostic nutritional index was calculated for all patients (PNI = [10 × serum albumin {g/dl}] + [0...

Following severe peripheral nerve injury (PNI), regeneration is often insufficient and functional recovery is incomplete. Any agents that limit the spread of neural tissue damage may enhance the nerve regeneration. In this regard, statins have been shown to have neuroprotective properties. We investigated the effects of Lovastatin against sciatic nerve crush injury in male Wistar Rats. Lovastatin or vehicle was given parenteraly to rats for 7 days postoperative. In Lovastatin treatment groups, a single dose of agent (2 and 5mg/kg) was administered daily...
