(15) Dr Umair A Shah, executive director of the Harris County department of public health, said, “It’s probably not a case of if we get Zika in our native mosquitoes, it’s probably a case of when we get Zika in our native mosquitoes.” Zika is a subtropical virus transmitted by the Aedes aegypti and Aedes albopictus mosquitoes, part of a group of diseases known as arboviruses, short for arthropod-borne viruses.

(17) The paper ends with identification keys for both adult and immature stages as well as for arthropod indoor fecal traces.

(19) In arthropods, reflex modulation can occur in the sensory receptors themselves and in neurons that discharge during locomotion.
(20) The inhibition assay for mite allergen was reproducible in the presence of protein concentrations of added plant, fungal, arthropod and animal extracts in excess of the protein concentrations that occur under the operational mite assay conditions.
Tentorium
Definition:
(n.) A fold of the dura mater which separates the cerebellum from the cerebrum and often incloses a process or plate of the skull called the bony tentorium.
Example Sentences:
(1) The region of the tentorium and straight sinus can occasionally give rise to a vermiform appearance (the "AVM artifact").
(2) In children with tumors above the tentorium, only a reduction in the use of cerebral angiography and radioisotopic scanning was demonstrated.
(3) A zone of the tentorium cerebelli that is relatively poor in vessels and nerves and comparatively favourable for incision is established.
(4) A cavernous angioma of the tentorium cerebelli, first disclosed by perinatal serial ultrasonographic studies, was extirpated totally without remarkable neurological deficit in a neonate.
(5) The procedure involves section of the less dominent transverse sinus and the tentorium.
(6) This technique has also led to a better delimitation and sometimes a direct observation and spatial localization of some anatomical structures above and below the tentorium.
(7) A case of abnormal uptake of gallium in the tentorium cerebelli secondary to rheumatoid pachymeningitis is presented.
(8) Among them, 97 (23.4%) patients showed the appearance of TSAH in the Sylvian fissures, tentorium cerebelli, cortical sulci, basal cisterns and interhemispheric fissures.
(9) In those cases without spina bifida, ventricular enlargement should occur early and be greatest in the forebrain, driving the tentorium and posterior fossa structures downward.
(10) The technique is also widely applicable for closing (or suturing) the dura following any procedure through a small opening, such as the dural tears occasionally encountered during lumbar or cervical discectomy, or tacking the tentorium during a craniotomy.
(11) The tentorial sinuses were classified into four groups: Group I, in which the sinus received venous blood from the cerebral hemisphere; Group II, in which the sinus drains the cerebellum; Groups III, in which the sinus originates in the tentorium itself; and Group IV, in which the sinus originates from a vein bridging to the tentorial free edge.
(12) In the preliminary study, a dry human skull with an artificial "tentorium" made of thick paper was prepared to decide the fundamental plane for volume measurement by CT scan.
(13) The configuration of Model III is the same as Model II but more detailed anatomical features of the head interior were added, such as, cerebral spinal fluid (CSF); falx cerebri, dura, and tentorium.
(14) These two disseminated tumors had attachments to the inferior surface of the cerebellar tentorium and the dura mater of the parietal convexity, respectively, and they were fed by external carotid artery branches, like meningiomas.
