Transverse myelitis is a focal inflammatory disorder of the spinal cord which may arise due to different etiologies. Transverse myelitis may be idiopathic or related/secondary to other diseases including infections, connective tissue disorders and other autoimmune diseases. It may be also associated with optic neuritis (neuromyelitis optica), which may precede transverse myelitis. In this manus...

Background: To clarify the mechanism of sperm penetration through the zona pellucida, the flagellar force generated by a hyperactivated spermatozoon was evaluated using the resistive force theory applied to the hyperactivated flagellar waves that were obtained from the mammalian spermatozoa. Materials and Methods: The hydrodynamic calculation of the flagellar force of the activated (non-hyperac...

We classify transverse Hopf links in the standard contact 3-space up to transverse isotopy in terms of their components’ self-linking number. 1 The statement of result A contact structure on a 3-manifold is a completely non-integrable 2-plane field on it. Let ξ0 be the standard contact structure on 3-space R 3 = {(x, y, z)}, that is, a 2-plane field on R defined by the kernel of the 1-form dz −...

BACKGROUND AND PURPOSE Transverse sinus thrombosis can have nonspecific clinical and radiographic signs. We hypothesized that the novel "sigmoid notch sign" (on head CT) can help differentiate transverse sinus thrombosis from a congenitally atretic sinus among individuals with absent signal in 1 transverse sinus by MR venography. METHODS We retrospectively evaluated 53 subjects with a unilate...

STUDY DESIGN A prospective sonographic study. PURPOSE To verify the effectiveness of simultaneous application of two landmarks, Doppler image of the vertebral artery and shape of the transverse tubercle of the seventh cervical (C7) vertebra. OVERVIEW OF LITERATURE Counting upwards from the C7 vertebra which only has a posterior tubercle of the transverse process is a commonly used method fo...

Acute transverse myelitis is a rare neurologic condition that has an estimated incidence of up to 3 per 100,000 patient years (0.003%). Although rare, acute transverse myelitis can have devastating neurologic effects with up to two-thirds of patients having a moderate to severe degree of residual disability. The term acute transverse myelitis was previously reserved for idiopathic cases, but cu...

BACKGROUND Transverse myelitis has been reported in association with vaccination, including influenza vaccination. OBJECTIVE To describe a case of longitudinally extensive transverse myelitis associated with vaccination with a nasal attenuated novel influenza A(H1N1) vaccine. DESIGN Case report. SETTING Sanford University of South Dakota Hospital. Patient A 27-year-old woman with longitud...

The Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory is the first accelerator facility that can accelerate, store and collide spin polarized proton beams. This development enables a physics program aimed at understanding how the spin of the proton results from its quark and gluon substructures. Spin states that are either parallel (longitudinal) or perpendicular (transve...
