The Blume Emery Griffiths model is investigated by use of the cluster variation method in the pair approximation. We determine the regions of the phase space where reentrant phenomenon takes place. Two regions are found, depending on the sign of the reduced quadrupole quadrupole coupling strength ξ. For negative ξ we find Para-Ferro-Para and Ferro-Para-Ferro-Para transition sequences; for posit...

High respiratory obstructive sleep apnea syndrome (OSAS) is a potentially disabling condition, characterized by excessive daytime sleepiness, disruptive snoring, recurrent episodes of apnea (or hypopnea) and nocturnal hypoxemia. It is a sign of increased pharyngeal airflow resistance (apnea hypopnea index (AHI ≥ 5). Twelve patients suffering from mild-to-severe OSAS received CPAP treatment and ...

As part of a series studies regarding the microbiota in manned space environments, we isolated fungal strains from nasal and pharyngeal smears saliva 21 astronauts preflight, in-flight, postflight. On ground, 120 43 genera environmental fungi were astronauts. The dominant Cladosporium, Penicillium, Aspergillus. Only 18 four inside International Space Station. These are currently thought to be h...

BACKGROUND The purpose of this study is to examine the expression levels of lymphatic endothelial markers in colorectal cancer and to explore the correlation between the expression levels of markers and lymph node status. METHODS Forty-seven paired fresh tumor tissues and para-cancerous tissues were collected from colorectal cancer patients who received surgical treatment between August 2015 ...

Introduction: Concern has been raised that premolar extraction reduces arch length and diminishes space for the tongue, thus forcing the tongue to be retro-positioned. There is speculation that this retro-position of the tongue reduces pharyngeal space leading to breathing problems, notably obstructive sleep apnea. There is little evidence that retracting teeth into extraction spaces changes ai...

It has been hypothesized that the pressure in tissues surrounding the upper airway is one of the determinants of the size and shape of the upper airway. To our knowledge, this pressure has not been measured. The purpose of this study was to test whether the pressure in a tissue lateral to the upper airway, the lateral pharyngeal fat pad pressure (Pfp), differs from atmospheric and pharyngeal pr...

OBJECTIVES The study was aimed to evaluate the pharyngeal airway linear measurements of untreated skeletal class II subjects with normal facial vertical pattern in prognathic maxilla with orthognathic mandible and orthognathic maxilla with retrognathic mandible. MATERIALS AND METHOD the sample comprised of lateral Cephalograms of two groups (30 each) of class II malocclusion variants. Group 1...

OBJECTIVE To explore the expression and clinical significance of IncRNA-CCAT and EMT related molecule E-cadherin and N-cadherin in colorectal cancer. METHODS The expression of IncRNA-CCAT1, E-cadherin and N-cadherin in 37 colorectal cancer tissue and para-carcinoma tissue was detected using qRT-PCR method, and the correlation of expression level with clinical and pathological features was stu...
