OBJECTIVE Bilateral vestibulopathy (BV) leads to a bilateral deficit of the vestibulo-ocular reflex and has various aetiologies. The main goal of this study was to determine the frequency and degree of recovery or worsening of vestibular function over time. METHODS 82 patients (59 males, 23 females; mean age at the time of diagnosis 56.3 (SD 17.6) years) were re-examined 51 (36) months after ...

OBJECTIVE The effects of 4-aminopyridine (4-AP) on downbeat nystagmus (DBN) were analysed in terms of slow-phase velocity (SPV), stance, locomotion, visual acuity (VA), patient satisfaction and side effects using standardised questionnaires. METHODS Twenty-seven patients with DBN received 5 mg 4-AP four times a day or placebo for 3 days and 10 mg 4-AP four times a day or placebo for 4 days. R...

Many patients suffering from angina pectoris are treated with percutaneous coronary intervention (PCI) and quickly develop angiographic renarrowing, or restenosis, at the site of PCI treatment. Restenosis is thought to arise from the combinatorial activation of thrombotic and inflammatory responses. The inflammatory response responsible for restenosis is also thought to involve the activation o...

The pathomechanism of downbeat nystagmus (DBN) remains controversial but each mechanism has to account for 1) its gazeevoked vertical centripetal component which increases on down and lateral gaze,1 and 2) the vertical bias component of the upward slow phase velocity (SPV) in gaze straight ahead. The vertical velocity bias of DBN has a gravity-dependent component which leads to maximal drift ve...

A terahertz (THz) superimposed perfect vortex (SPV) beam is generated by using a designed optimal phase element (SOPE) at 0.3 THz. As the topological charge changes, ring radius of THz SPV beams remains almost constant in experiment, whose relative error only 0.96%. The property confirmed. intensity profile with equally spaced breakpoints. carried can be judged directly identifying number linea...

Varying weather specifically temperature and irradiation have a significant impact on Solar Photo Voltaic (SPV) output performance efficiency. Both the voltage power are unstable due to unwanted solar fuel variation. Therefore, Maximum Power Point Tracking (MPPT) plays an important role in case of SPV. Although different MPPT techniques imposed mitigate above-said issues, Perturb Observe (P&amp...

Solar photovoltaic (SPV) system fault diagnostics is vital in advanced supervision because it can alert users to catastrophic failure or greater risks. To provide green and clean energy using solar, mandatory analyse various faults associated with which result deficit breakdown may lead fire hazards are often difficult avoid. Hence, as an endeavour improve the efficiency level, more study begin...
