Vertebrate hearing and balance are based in complex asymmetries of inner ear structure. Here, we identify retinoic acid (RA) as an extrinsic signal that acts directly on the ear rudiment to affect its compartmentalization along the anterior-posterior axis. A rostrocaudal wave of RA activity, generated by tissues surrounding the nascent ear, induces distinct responses from anterior and posterior...

Introduction: Lupus vulgaris is the most common form of cutaneous tuberculosis caused by contiguous spread from an underlying infective focus or lymphatic or hematogenous spread. It can also develop at the site of direct inoculation (e.g., tattooing and ear piercing) or Bacillus Calmette-Guerin vaccination. The solitary involvement of the pinna is rare and may face clinicians with a diagn...

We report a case of malignant melanoma of Eustachian tube with extension to the middle ear cavity and nasopharynx in a 51-year-old woman who presented with right ear fullness. Computed tomography showed a soft tissue mass in the middle ear cavity and caused the widening and eroding of the bony eustachian tube. Magnetic resonance imaging showed well enhancing mass in eustachian tube extending na...

There are several techniques for the prevention of dog-ear. All have their own disadvantages, since mostly they lengthen wound. The current technique prevents dog ear during inverted-T breast lift and reduction without lengthening wound or creating tension while closing

The aim of the present study was to investigate the effect of ear asymmetry, order of testing, and gender on transient-evoked otoacoustic emission (TEOAE) pass rates and response levels in newborn hearing screening. The screening results of 879 newborns, of whom 387 (study group) passed screening successfully in only one ear in the first TEOAE screening, but passed screening successfully in bot...

OBJECTIVE The repair of dilated ear lobules after gauge ear piercing is increasingly performed to restore the natural ear appearance and shape for esthetic, professional, or social reasons. Because of a deficit of remaining lobule tissue, reconstruction of this area can be challenging. Many have described the repair of partial cleft ear lobule defects, but few focus on the repair of dilated ear...

introduction: otalgia is one of the complaints which may occur at any age. the etiology of the pain may be in the ear, structures around the ear or other head and neck structures. this is caused by the complex nervous connections in the head and neck areas, the ear, the pharynx and the nose. since understanding the etiologies of referred otalgia can help in the assessment and treatment of the d...

BACKGROUND: Alternative furrow irrigation method is an effective procedure to reduce the amount of irrigation water in arid areas for economic production. OBJECTIVES: Assessment seed yield, its components and morphological characteristics of corn affected different level of irrigation regime and super absorbent polymer (SAP) under warm and dry climate con...

A field experiment was conducted during the winter (rabi) seasons of 2017–18 and 2018–19 at Rajasthan College Agriculture, Maharana Pratap University Agriculture Technology, Udaipur, Rajasthan, to find out best integrated nutrient management strategy in barley (Hordeum vulgare L.). The correlation regression were studied between yield attributes as influenced by these treatments. laid a randomi...
