Although migraine is a common neurological condition, the pathomechanism is not yet fully understood. Activation of the trigeminovascular system (TVS) has an important function in this disorder and neurogenic inflammation and central sensitization are important mechanisms underlying this condition. Nitroglycerin (NTG) infusion in rats closely mimics a universally accepted human model of migrain...

Parovarian cysts are common disorders which constitute 10-20% of adnexal masses in pathologically verified series. Most of these cysts are benign, and borderline parovarian tumors are rare and documented only as case reports in the literature. The study was aim to examine the sonographic features of parovarian borderline tumors for making an accurate preoperative diagnosis. Four patients (mean ...

OBJECTIVE This study was aimed at analysing the association between socioeconomic indicators and adolescents' physical activity and health-related fitness. METHODS The study involved 716 adolescents from both genders whose age ranged from 10 to 18 years-old (46.8% male) who answered a questionnaire for estimating their habitual physical activity, socioeconomic status; two health-related physi...

A semi-quantitative dermal exposure assessment method based on visual observations of fluorescence images was presented by Fenske in 1988. We adapted the method to Nicaraguan working conditions and evaluated its performance. Thirty-two farmers applied chlorpyrifos and methamidophos marked with Tinopal CBS-X(R). Skin fluorescent depositions were observed with a portable UV lamp in a foldaway dar...

Ovarian cancer is the foremost cause of gynecological cancer death in the developed world, as it is usually diagnosed at an advanced stage. In this paper we discuss current issues, the efficacy and problems associated with ovarian cancer screening, and compare the characteristics of ovarian cancer subtypes. There are two types of ovarian cancer: Type I carcinomas, which are slow-growing, indole...

Retail prices are volatile and decrease over time in many markets for differentiated durable goods. Consumers in these markets have an incentive to delay their purchase and wait for lower prices. This paper uses a novel data set from a price alert service for TVs sold on Amazon.com to estimate substitution patterns across products and over time. Users of a price alert service submit a price thr...

The focus of this paper is estimating articulatory movements of the tongue and lips from acoustic speech data. While there are several potential applications of such a method in speech therapy and pronunciation training, performance of such acoustic-to-articulatory inversion systems is not very high due to limited availability of simultaneous acoustic and articulatory data, substantial speaker ...

BACKGROUND Patients who have undergone cardiac surgery are generally mechanically ventilated postoperatively. Early postoperative extubation is currently recommended in anesthesia guidelines. No current technology can accurately, non-invasively, measure respiratory competence after extubation. Pulse oximetry has been helpful, but this is a late indicator of respiratory compromise. A novel, non-...

Abstract To realize the encryption of document information, authority authentication, and traceability historical records, we propose a trusted verification scheme (TVS) for office documents to ensure security. Specifically, is realized by timestamps, smart contracts (or chaincode), other blockchain technologies. It based on features blockchain, such as security, credibility, immutability, netw...

In this study, co-composting of food waste and green waste at low initial carbon to nitrogen (C/N) ratios was investigated using an in-vessel lab-scale composting reactor. The central composite design (CCD) and response surface method (RSM) were applied to obtain the optimal operating conditions over a range of preselected moisture contents (45-75%) and C/N ratios (13.9-19.6). The results indic...
