A 5-year-old gelding used for showing was presented surgical repair of a full-thickness 15 mm diameter defect in the right pinna, which had occurred as delayed complication following laser excision sarcoid. The resulted progressive deformity ear, and horse considered at risk further injury if became entrapped on fixed object. Two artificial dermis meshes were inserted to encourage formation gra...

This study has characterized constrictions of small cutaneous arteries in the guinea pig ear in response to electrical stimulation of the cervical sympathetic nerve (SNS) in vivo. Video microscopy and on-line image analysis were used to examine diameter changes of ear arteries (80-140 μm resting diameter) in anesthetized guinea pigs. Trains of 50-300 impulses, but not single pulses or short tra...

Ear row number (ERN) is not only a key trait involved in maize (Zea mays L.) evolution but is also an important component that is directly related to grain yield. In this study, quantitative trait loci (QTLs) for ERN were detected across two F2 populations that were derived from a same cross between B73 with 16 rows (N = 233) and SICAU1212 with four rows (N = 231). As a result, 33 QTLs were ass...

In order to evaluation effect of different level of humic acid affected drought stress on seed yield, its components and morphological traits of corn a research farm was conducted according split plot experiment based randomized complete blocks design at three replication during 2015 year. Main factor included four irrigation regimes (90mm, 110 mm, 130 mm and 150mm evaporation from pan class A)...

A non-invasive method of measuring or estimating accurately the head-related transfer functions (HRTFs) and headphone transfer functions (HpTFs), i.e., the pressure at the eardrum rather than at the blocked ear canal entrance is called for. In this work, a miniature-sized acoustic pressure-velocity sensor is used to measure both pressure and velocity along the ear canals of human test subjects....

Traditionally, otologists have aimed to produce a clean, dry, safe ear with the best possible hearing result. More recently, "less invasively" has been added to this list of goals. The development of small-diameter, high-quality rigid endoscopes and high-definition video systems has made totally endoscopic, transcanal surgery a reality in adult otology and a possibility in pediatric otology. Th...

OBJECTIVE The objective of this research was to investigate the possible relationship between tinnitus and certain bony inner ear structures using computed tomography (CT). MATERIALS AND METHODS This was a prospective, controlled, double-blind study. The subjects of the study were divided into the following three groups: group 1 (G1), patients with unilateral sensorineural hearing loss (SNHL)...

A 27-year-old woman presented with a history of loss of balance and deafness in the left ear for 2 weeks. Computed tomography and arteriography demonstrated a giant aneurysm 49 mm in diameter in the posterior cranial fossa. Surgical removal of the aneurysm was unsuccessful.
