A substitute for rat milk [Messer et al., 1969 (1)] has been evaluated as a nutrient source to artificially feed rat pups from 4 days after birth. The rat milk substitute has a normal fat concentration, suboptimal protein concentration and a high carbohydrate concentration when compared to natural rat milk. Rat pups artificially reared on the mild(More)
Magnetic steering of an untethered ferromagnetic device in a living body has many advantages in the clinical fields. In this paper, the positioning and tracking methods of a ferromagnetic sphere have been compared with magnetic resonance phantom images obtained with three different imaging sequences, spin echo, gradient echo, and selected positive contrast(More)
We introduce a square coil system for remote magnetic navigation of a magnetic device without any physical movements of the coils. We used three square-Helmholtz coils and a square-Maxwell coil for magnetic propulsion of a small magnet along the desired path. All the square coils are mountable on a cubic frame that has an opening to accommodate a living(More)
STUDY DESIGN Histological examination of human spinal ventral roots. OBJECTIVES To determine the proportion of unmyelinated fibers in human ventral roots from the 4th cervical (C4) to 2nd sacral (S2) segment, and to evaluate differences in the proportions of unmyelinated fibers between the cervical, thoracic, lumbar and sacral segments, and between(More)
Labrador Retriever puppies (3 kg) were fed L-amino acid (L-AA) diets, containing the equivalent of 14% protein, to determine dietary argnine requirements for optimal growth and maintenance of normal intermediary metabolism. Growth and food consumption were depressed by decreasing the dietary arginine concentration. Urinary citrate and orotate increased with(More)
We introduce a magnetic navigation of a small magnet using four stationary coils. We used a Maxwell gradient coil to get magnetic propulsion force and three Helmholtz coils to control the moving direction of the magnet in the magnetic navigation. Using a three-channel coil driver with output capacity of 320A, we performed magnetic navigation of a small(More)
Let H4n−1(H) be the quaternionic Heisenberg group of real dimension 4n− 1 and let In denote the maximal order of the holonomy groups of all infra-nilmanifolds with H4n−1(H)-geometry. We prove that I2 = 48. As an application, by applying Kim and Parker’s result, we obtain that the minimum volume of a 2-dimensional quaternionic hyperbolic manifold with k(More)
BACKGROUND Ocular motor dysfunction is common in patients with head trauma. Also, traumatic lateral gaze palsy is usually associated with brain stem lesion, peripheral nerve injury with or without basilar skull fracture and lateral rectus muscle injury or entrapment. However, isolated bilateral abducens nerve palsy is extremely rare. CASE STUDY This study(More)
