OBJECTIVES We developed a standardized method of minimally invasive transoral laryngeal (ToL) bipolar electromyography (EMG) for evaluation of recurrent laryngeal nerve (RLN) recovery after a controlled crush injury in a rat model. METHODS Ten 200- to 250-g Sprague-Dawley rats underwent a controlled crush injury to the left RLN performed with 60 seconds of use of a calibrated aneurysm clamp w...

Detailed Accomplishments in 2008-09: Processors are concerned about peel integrity of CMNP-treated fruit. We conducted 2 trials in March and April with Valencia oranges to determine the postharvest effect of CMNP applied to canopies for the purpose of loosening fruit on fruit crush force, peel puncture resistance, and peel puncture depth. Fruit were collected during our harvesting trial studies...

Previous work has led to the development of a crash energy management (CEM) system designed to distribute crush throughout unoccupied areas of a passenger train in a collision event. This CEM system is comprised of crush zones at the front and rear ends of passenger railcars. With a consist made up of CEM-equipped cars, the structural crush due to a collision can be distributed along the length...

BACKGROUND Ipsilateral C7 nerve transfer is an available procedure in C5C6 2-root avulsion injury of the brachial plexus. However, concomitant injury of a normal-looking C7 cannot be ruled out. The efficiency of a concomitant injury of C7 transfer was investigated. METHODS Forty-two Sprague-Dawley rats were randomly assigned to 5 groups. They all underwent a 2-stage procedure. In the first st...

MicroRNA (miRNA) has great potential to treat a wide range of illnesses by regulating the expression of eukaryotic genes. Biomaterials with high transfection efficiency and low toxicity are needed to deliver miRNA to target cells. In this study, a biodegradable and biocompatible cationic polymer (PDAPEI) was synthetized from low molecular weight polyethyleneimine (PEI1.8kDa) cross-linked with 2...

Background: Crush-syndrome usually resulting from earthquake and other natural disaster causes mortality morbidity. A multistoried garment factory collapsed in Savar, Dhaka, Bangladesh on 24th April 2013 with about 4000 workers. Among the rescued victims, many of them develop crush – syndrome AKI that led to a man-made renal Bangladesh. We analyzed outcome severe patient who required replacemen...

Although calcitonin gene-related peptide is a recognized pain transducer, the expression of calcitonin gene-related peptide in primary afferents may be differentially affected following different types of nerve injury. Here, we examined whether different calcitonin gene-related peptide expression patterns in primary afferents contributes to distinct sensory disturbances in three animal models o...

We performed this study to evaluate the effect of cavernous nerve (CN) traction on erectile function in rats. Thirty-two 8- week-old Sprague-Dawley rats were divided into four groups: control, 1-minute CN traction, 2-minute CN traction, and 2-minute CN crush. CN traction was performed using a glass hook with a tensile force of 0.2 Newton. One month later, the mean arterial pressure (MAP) and in...

This research work aimed to enhance the crashworthiness of existing automobile bumper minimize crash injuries. As per simulation results weight carbon polyamide-based is reduced in comparison with steel by 9.7 kg or 47.5%, this reduction 38% increase fuel economy has been estimated. The energy absorption capability polyamide improved from and aluminum 11.15% 16.3% respectively modification, imp...
