Microbial growth and exposure to UV light is a persistent global concern resulting in food spoilage, therefore, smart packaging is crucial for the availability of safer and quality food. Present work describes fabrication of chitosan (CH) and gelatin (GL) based nanocomposite films by introducing green source, highly fluorescent Vachillia nilotica gum-derived carbon dots (VNG-CDs). The VNG-CDs and incorporated CH/GL nanocomposite films were characterized by UV-Visible, FTIR, XRD, SEM and TGA analysis. The FTIR and XRD data revealed that VNG-CDs, chitosan, gelatin, and glycerol are combined/interlinked to form homogeneous nanocomposite films...

INTRODUCTION: Benign paroxysmal positional vertigo (BPPV) is a vestibular disease characterized by brief  positional vertigo. When examined, characteristic patterns of positional nystagmus (PN) are found with specific head position changes. Previous studies have shown a high prevalence of PN among vestibular healthy subjects. Considering the current diagnostic criteria of BPPV and the potentially high prevalence of PN in healthy individuals, this raises the question of potential over diagnosing BPPV, if diagnostics are based exclusively upon objective findings...

UNLABELLED: Videonystagmography (VNG) is useful and reliable in diagnosing vertigo. Benign Paroxysmal Positional Vertigo (BPPV) is the most common peripheral vestibular disorder in adults, and posterior canal is the commonest canalinvolved. The treatment of choice for posterior canal BPPV is repositioning manoeuvres. Epley and Semontmanoeuvres are the two most commonly used treatment manoeuvres for the management of posterior canalBPPV. In this study, we use VNG to compare the two. Epley Repositioning Manoeuvre was found to be moreeffective than Semont Liberatory Manoeuvre...

Massive resection of a malignant tumor of the head and neck region often requires loss of critical nerves, including the spinal accessory nerve. Recently, vascularized nerve grafts (VNGs) have been used to repair facial and other nerve defects with successful outcomes, even in cases involving factors that can inhibit nerve regeneration, such as radiotherapy. However, the effectiveness of these nerve grafts against postoperative radiotherapy has yet to be explored. We report the first successful case in reconstructing a spinal accessory nerve defect after total left parotidectomy with radical neck dissection, using a vascularized vastus lateralis motor nerve graft and an anterolateral thigh flap based on the lateral circumflex femoral system, with great shoulder function outcomes even after postoperative radiotherapy...

INTRODUCTION:  Vestibular dysfunction is a debilitating disorder frequently encountered in neurological and otological settings. The vestibular system is a complex network between peripheral and central mechanisms. This innate complexity of the vestibular system necessitates objective test procedures for evidence-based diagnostic formulations and intervention. Objective tests aid in the evaluation of both peripheral and central vestibular pathologies. Establishing and availability of comprehensive normative data for these objective tests is crucial for clinicians and researchers alike...
