OBJECTIVE Headache is one of the most common neurologic problems in children and adolescents. Primary headache including migraine and tension-type headache comprises the vast majority of headaches and are associated with marked incidence, prevalence, and individual and social cost. We aimed to assess demographic characteristics and to compare some factors related to primary headaches in childre...

OBJECTIVE To determine the prevalence, characteristics and impact of headache among university students. METHOD The criteria established by the International Headache Society were used to define the primary headache subtypes and the Migraine Disability Assessment Questionnaire (MIDAS), to assess the disability. The students were then grouped into six categories: [1] migraine; [2] probable mig...

Background. Our aim was to investigate the association between migraine, tension type headache, and metabolic syndrome. Methods. Presence of tension type headache and migraine was investigated in 120 patients diagnosed as metabolic syndrome. The severity of the headache was recorded according to the visual analog scale. Results. Mean age of the patients was 54.41 ± 11.60 years (range, 29-84 yrs...

The requirement for Watson-Crick base pairing surrounding a nick in duplex DNA to be sealed by DNA ligase is the basis for oligonucleotide ligation assays that distinguish single base mutations in DNA targets. Experiments in a model system demonstrate that the minimum length of oligonucleotide that can be joined differs for different ligases. Thermus thermophilus (Tth) DNA ligase is unable to j...

INTRODUCTION Despite increasing use of testosterone therapy (TTh) for men with testosterone deficiency (TD), there remains uncertainty determining who is a candidate for treatment. AIM The aim if this study was to report the opinions of international experts on TTh, as initially presented at the meeting of the World Meeting on Sexual Medicine in Chicago, United States in August 2012. METHOD...

The role of testosterone therapy (TTh) in cardiovascular disease (CVD) outcomes is still controversial, and it seems will remain inconclusive for the moment. An extensive body of literature has investigated the association of endogenous testosterone and use of TTh with CVD events including several meta-analyses. In some instances, a number of studies reported beneficial effects of TTh on CVD ev...

Anax junius is a large dragonfly that regulates thoracic temperature (Tth) during flight. This species, like several other intermittently endothermic insects, achieves control of Tth at least in part by increasing circulation of hemolymph to the abdomen at high air temperature (Ta), thus facilitating heat loss from the thorax. In this paper, I demonstrate that heat transfer to the head is also ...

Background: Migraine is the most common type of headache in the world and is one of the most important causes of patients to come to the neurologist office.
