Background:Sinusitis is a common diagnosis that can be erroneously associated with routine weather‐related barometric pressure *** actuality,these pressure changes likely exacerbate migraine headaches,which can cause facial pain and pressure rather than true sinus ***:The present study sought to characterize the representation of both sinusitis and migraine in association with barometric pressure changes across websites on the ***:An Internet search for relevant terms was conducted,and content of the resulting pages was assessed for associations between weather‐related pressure changes and either sinusitis or *** in reported results across different subtypes of Internet sources were *** primary outcomes measured were(1)whether a given media source associated barometric weather changes with sinusitis,(2)whether that source associated barometric weather changes with migraine,and(3)treatment options offered by that ***:Of the 116 included webpages,36(31.03%)associated sinusitis and routine barometric pressure *** these,10(27.77%)were otolaryngology practice ***‐seven webpages(57.76%)associated migraine and routine barometric pressure *** these,nonotolaryngology webpages were more likely to report this ***:Otolaryngology practice sites were observed to be the most frequent professional medical resource reporting the unsubstantiated claim that routine barometric pressure changes are associated with *** sources were more likely to link weather‐related pressure changes to *** results suggest that opportunities exist for otolaryngology practice sites to educate patients ab.ut nonrhinogenic headache etiologies.

Myosin *** Regulates Protonemal Patterning and Developmental Timing in the Moss Physcomitrella patens

Plants have two classes of myosins. While recent work has focused on class XI myosins showing that myosin XI is responsible for organelle motility and cytoplasmic streaming, much less is known ab.ut the role of myosin VIII in plant growth and development. We have used a combination of RNAi and insertional knockouts to probe myosin VIII function in the moss Physcomitrella patens. We isolated Amyo8ab.DE plants demonstrating that myosin VIII is not required for plant viab.lity. However, myosin VIII mutants are smaller than wild-type plants in part due to a defect in cell size. Additionally, Amyo8ab.DE plants produce more side branches and form gametophores much earlier than wild-type plants. In the ab. sence of nutrient media, Amyo8ab.DE plants exhibit significant protonemal patterning defects, including highly curved protonemal filaments, morphologically defective side branches, as well as an increase in the number of branches. Exogenous auxin partially rescues protonemal defects in Amyo8ab.DE plants grown in the ab.ence of nutrients. This result, together with defects in protonemal branching, smaller caulonemal ceils, and accelerated development in the Amyo8ab.DE plants, suggests that myosin VIII is involved in hormone homeostasis in P patens.
