Immobilization of enzymes is one of the most promising methods in enzyme performance enhancement, including stability, recovery, and reusability. However, investigation of suitable solid support in enzyme immobilization is still a scientific challenge. Polyethersulfone (PES) and aminated PES (PES-NH2) were successfully synthesized as novel materials for immobilization. Membranes with various po...

Phthalate esters (PEs) are plasticizers used in many plastic products, food packaging materials, and medical bags. The widespread use of PEs has led to ubiquitous environmental contamination and human-exposure. Several epidemiological studies have indicated that exposure to PEs, especially during the prenatal period, induces adverse effects, including developmental and behavioral abnormalities,...

PURPOSE The primary purpose of this study was to assess the relationship between pharyngoesophageal segment (PES) configuration and narrow-band spectrogram of tracheoesophageal voices. METHODS This study included 30 total laryngectomees tracheoesophageal speakers. Patients were assessed by videofluoroscopy (VF), during deglutition and voicing, and the vowel /a/ was recorded for spectrographic...

OBJECTIVES Pseudoexfoliation syndrome (PES) is a common age-related fibrillopathy related to accumulation of pseudoexfoliation material (PEM) in certain places in the body, especially blood vessels. Erectile dysfunction (ED) is another condition related to vascular pathology and in this study it is aimed to identify the relationship between ED and PES. MATERIALS AND METHODS Data of 92 patient...

Orthotics are frequently prescribed for the conservative treatment of musculoskeletal disorders of the foot and ankle such as pes cavus or pes planus. Pes cavus is defined as having a high arch whereas pes planus is defined as having a low arch in the foot. The normal population is considered to have an arch in between pes cavus and pes planus. Orthotics are thought to alter the motion of the b...

Membrane separation is an important processing technology used for separating food ingredients and fractionating value-added components from food processing byproducts. Long-term performance of polymeric membranes in food protein processing is impeded by the formation of fouled layers on the membrane surface as a result of protein adsorption onto the membrane surface. Surface modification of sy...

The aim of the present study was to evaluate diaphragmatic strength in patients with unilateral diaphragmatic paralysis and to determine whether patients with recent diaphragm paralysis develop lower inspiratory pressure than patients with longstanding diaphragmatic paralysis. Twenty patients (16 men and 4 women, 62+/-12 years) and six control subjects were included (4 men and 2 women, 53+/-15 ...

Approximately 20% of mechanically ventilated patients experience post-extubation stridor (PES) and reintubation, which subsequently may lead to an increased risk of morbidity and mortality. The risk of PES development is significantly higher in obese patients. Low air leakage between the endotracheal tube and the trachea, following cuff deflation, may indicate a higher risk for the development ...

Parthenogenesis is the process by which an oocyte develops into an embryo without being fertilized by a spermatozoon. Although such embryos lack the potential to develop to full term, they can be used to establish parthenogenetic embryonic stem (pES) cells for autologous cell therapy in females without needing to destroy normally competent embryos. Unfortunately, the capacity for further differ...
