Normalized pulse volume (NPV) derived from the ear has the potential to be a practical index for monitoring daily life stress. However, ear NPV has not yet been validated. Therefore, we compared NPV derived from an index finger using transmission photoplethysmography as a reference, with NPV derived from a middle finger and four sites of the ear using reflection photoplethysmography during base...
OBJECTIVE To determine the clinical serum levels of carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA19-9), individually and in combination, for the diagnosis of 50 healthy subjects and 150 cases of esophageal, gastric, and colon cancers. METHODS The sensitivities of the two markers were compared individually and in combination, with specificity set at 100%. Receiver operating ...
Eight lepidopteran cell lines were established recently and their susceptibility to different insect viruses was studied. Two Spodoptera litura cell lines from the larval and pupal ovaries, were found highly susceptible to S. litura nuclear polyhedrosis virus (SLNPV, 5-6 x 10(6) NPV/ml). The Helicoverpa armigera cell line from the embryonic tissue was highly susceptible to H. armigera NPV (HaNP...
BACKGROUND Glioblastoma multiforme is the most common form of primary brain tumor, often characterized by poor survival. Glioblastoma initiating cells (GICs) regulate self-renewal, differentiation, and tumor initiation properties and are involved in tumor growth, recurrence, and resistance to conventional treatments. The sonic hedgehog (SHH) signaling pathway is essential for normal development...
The isoelectric points of three baculoviruses, Trichoplusia ni nuclear polyhedrosis virus (NPV), T. ni granulosis virus, and Spodoptera littoralis NPV were identified by cell electrophoresis. At neutral pH polyhedra were negatively charged. T. ni NPV polyhedra were reacted with a number of reagents which could potentially attach to or degrade their surface structure. This gave information on th...
چکیده شب پره پشت الماسی (diamondback moth) یا بیدکلم، plutella xylostella (l.) (lepidoptera: plutellidae) یکی از مهمترین آفات گیاهان خانواده چلیپائیان در سراسر دنیا می باشد. این حشره در سالهای اخیر آفتی مخرب برای کلم کاری های استان تهران بوده است. در بین بالپولکداران، این شب پره بالاترین مقاومت را به آفتکش های شیمیایی نشان داده است. بنا به نظر بسیاری از محققین، برای از بین بردن مشکل مقاومت این...
Idiopathic normal pressure hydrocephalus (iNPH) is a neuropsychiatric syndrome characterized by gait disturbance, cognitive impairment and urinary incontinence that affect elderly individuals. These symptoms can potentially be reversed by cerebrospinal fluid (CSF) drainage or shunt operation. Prior to shunt operation, drainage of a small amount of CSF or "CSF tapping" is usually performed to as...
STUDY OBJECTIVE To evaluate the efficacy of negative pressure ventilation (NPV) in avoiding or reducing apneas and related hypoxemia and respiratory acidosis during laser therapy (LT) of endobronchial lesions. DESIGN A prospective, controlled, randomized study. SETTING An operating theater of a respiratory endoscopy and laser therapy unit. POPULATION AND INTERVENTION: Twenty-seven consecuti...
