Abstract:   Background: The most important and complex phenomenon of respiratory function of the nose is related to different nasal anatomy. The differences in facial anatomic structure between different races may also be reflected in nasal resistance and airflow. Caucasians has different facial anatomic structure which is the reflection of intranasal resistance or consequence of airflow. The...

Background: Nasal continuous positive airway pressure (NCPAP) is an effective method of ventilation in newborns with respiratory distress syndrome (RDS). Using an appropriate nasal skin care protocol is identical to prevention or reduction of nasal skin breakdown in those who receive NCPAP. This study aimed to investigate the effectiveness of an evidence-based clinical care protocol on nasal sk...

Introduction: There is no single test as a gold standard for the diagnosis of allergic rhinitis (AR). The aim of this study was to assess the usefulness and validity of nasal smear as a quick, easy and inexpensive diagnostic method for diagnosis of allergic rhinitis. Materials and Methods: This study was conducted in a university hospital setting. Nasal smears were taken from 39 patients wit...

BACKGROUND The efficiency of nasal surgeries can be determined by objective or subjective methods. We have assessed the effect of nasal obstruction after different nasal surgeries using Acoustic Rhinometry (AR) and Nasal Obstruction Symptom Evaluation (NOSE) Scale. METHODS Between May 2011 and May 2012, 40 young adult patients and 10 healthy volunteers as control group who referred to ...

The human chemokine receptor (CKR) genes CCR2, CCR6, CCR7, CCR9, CCR10, CXCR4, and CXCR5 harbor one or two introns. CCR7, CCR9, CCR10, and CXCR5 introns, (but not CCR2, CCR6, and CXCR4 introns) encompass retrovirus-like inserts with the characteristics of SINEs (short interspersed nuclear elements) up to 300 nucleotides (nt) long. Other characteristic elements of the retroviral genome, such as ...

The article deals with the rationalization of production shaped inserts for casting rotors. theoretical part describes characteristics rotor casting, die technology, analysis existing technology inserts. main is focused on proposed technological process production, comparison and process. concludes a technical economic benefit solution evaluation work. Rationalization has its justification in d...

The results of an experimental study the combined enamelling technique are presented – enamel with granulation. Original inserts, decorated granules various colours and sizes, were obtained, use which expands possibilities decorative enamelling. It is shown that different degrees fusion grain on prepared base gives artistic effects. Spherical grains, qualitatively adhered to ground, give a more...

A microchannel heat exchanger effectively evacuates from a confined space. This paper attempts to gain insight into the combinatorial repercussions of simultaneously coupling two factors that affect microchannel’s performance, which channel size and micro-insert complexity are main contributors. With water as working fluid, an ANSYS-based numerical analysis was carried out for distinct sizes, 1...

Background and Objective: Nasal polyp is the most common benign mass of the nasal cavity and it is originated from nasal cavity or sinuses. Cytokeratins (CK) are intermediate filament proteins that provide mechanical support in epithelial cells. The purpose of this study was to compare the expression of cytokeratin 7 in epithelium of nasal polyps and nasal mucosa in chronic rhinosinusitis. Mate...

Introduction: Nose morphology depends on gender, ethnicity, and environmental conditions. It can be used in identification of the race and sex of persons whose identity is unknown. Nasal index is a useful tool in anthropometry. Methods: In this study, nasal parameters of Iranian males and females students were measured (nasal height, nasal width, and nasal index). This study was...
