[Show abstract][Hide abstract] ABSTRACT: Migraine and depression are common conditions that often coexist. The combination of several mechanisms may explain this comorbidity. A number of studies showed consistent association between depression and primary headache disorders including migraine; however, migraine with aura showed the strongest association with depression. This review highlights the background of migraine and depression, and summarizes studies that have investigated the risk for depression in migraine sufferers.
[Show abstract][Hide abstract] ABSTRACT: An equivalent circuit representation, which has been successfully
used in SAW transversely coupled resonator filter (TCF), is extended to
longitudinally coupled resonator filters (CRF). In TCF case usually two
fundamental modes are accurate enough to represent the passband but more
modes (most of them are `quasimodes' located outside of the stopband of
the structure) are needed for CRF. A mode identification method is
introduced in terms of equivalent motional parameters, R, L, and C and
then applied to two experimental examples, a narrow bandfilter on quartz
and a 3% bandwidth filter on 36° YX-LiTaO<sub>3</sub>. The results
confirm that it could be a useful tool for system designer as it is
compatible property with commercial electronic circuit CAD software. The
profiles of the main resonant modes detected by a laser probe are
presented in this paper
[Show abstract][Hide abstract] ABSTRACT: A 57-year-old woman presented with an escalation of her headaches which ultimately progressed to multiple strokes and death. MRI/MRA demonstrated diffuse vasospasm and other causes of stroke were excluded on premortem investigation and postmortem examination. Reversible MRI abnormalities, vasospasm on angiogram and fatal migrainous infarction have been previously reported; however, no previous case with this combination of clinical, imaging, and postmortem findings has been documented.
