Flexural rigidity of hawkmoth antennae depends on the bending direction.

To probe its environment, the flying insect controllably flexes, twists, and maneuvers its antennae by coupling mechanical deformations with the sensory output. We question how the materials properties of insect antennae could influence their performance. A comparative study was conducted on four hawkmoth species: Manduca sexta, Ceratomia catalpae, Manduca quinquemaculata, and Xylophanes tersa.

Wettability and morphology of proboscises interweave with hawkmoth evolutionary history.

Hovering hawkmoths expend significant energy while feeding, which should select for greater feeding efficiency. Although increased feeding efficiency has been implicitly assumed, it has never been assessed. We hypothesized that hawkmoths have proboscises specialized for gathering nectar passively.

Panhypopituitarism in a patient with a hypothalamic and pineal germ cell tumor.

Summary: Central diabetes insipidus (DI) is characterized by decreased release of antidiuretic hormone, resulting in a variable degree of polyuria. The etiologies are variable, with the vast majority of cases either being idiopathic or resulting from primary or secondary tumors. Such tumors include craniopharyngioma, Langerhans cell histiocytosis, or a variety of inflammatory, vascular, or granulomatous diseases.

Parathyroid hormone resistance from severe hypomagnesaemia caused by cisplatin.

A Case of West Nile Encephalitis That Develops into a Disease of Deep White Matter on MRI over a Two-Week Span.

We present a case of serologically proved West Nile encephalitis. This patient had a normal MRI on admission. Given that the patient's clinical picture had worsened during her admission, a repeat MRI was performed, which demonstrated diffuse disease in the deep white matter of the brain.

Three Cases of West Nile Encephalitis over an Eight-Day Period at a Downtown Los Angeles Community Hospital.

Since its introduction in New York City in 1999, the virus has spread throughout the entire North American continent and continues to spread into Central and Latin America. Our report discusses the signs and symptoms, diagnostics, and treatment of West Nile disease. It is important to recognize the disease quickly and initiate appropriate treatment.

Radioiodine treatment of differentiated thyroid cancer despite history of 'iodine allergy'.

Unlabelled: Radioiodine ((131)I) is a critical component in the treatment of differentiated thyroid cancer. We recently saw a patient with thyroid cancer who was hesitant to take (131)I treatment because he had previously encountered an allergic reaction to administration of iodine-containing radiocontrast agent for computed tomography (CT) scanning. We were able to administer (131)I treatment after discussion that his anaphylactic reaction was not due to iodine and that radioiodine ((131)I) treatment is unlikely to cause a reaction in the patient.
