Modulation of the asymmetry of sea urchin sperm flagellar bending by calmodulin [PDF]

, 1985
Sea urchin spermatozoa demembranated with Triton X-100 in the presence of EGTA, termed potentially asymmetric, generate asymmetric bending waves in reactivation solutions containing EGTA. After they are converted to the potentially symmetric condition by

Perfil hormonal de Progesterona durante o ciclo Estral em novilhas Nelore confinadas com Diferentes Ondas de Crescimento Folicular Plasma Progesterone Level during the Estrous Cycle in Nelore Heifers Confined with Two, Three and Four Waves of Follicular Growth

Revista Brasileira de Zootecnia, 2001
Efetuaram-se coletas diárias de sangue, de 16 novilhas Nelore confinadas, para análise de progesterona plasmática pelo método de radioimunoensaio (RIA). Os dias analisados para progesterona foram o dia zero (estro) e a cada três dias até o dia -1 e o dia

Quantification of steroid hormones in free‐ranging Apennine wolf Canis lupus italicus hair samples collected post‐mortem

Wildlife Biology, EarlyView.
After decades of dramatic reductions in their populations, Italian wolves have begun recolonizing parts of their historic range. This growth in populations can lead to potential conflicts with human activities, which remain the main cause of wolf mortality.

Luteinizing hormone concentrations in healthy horses and horses with trigeminal-mediated headshaking over an 8-hour period. [PDF]

, 2019
BackgroundTrigeminal-mediated headshaking results from a low threshold for firing of the trigeminal nerve. A seasonal component has been implicated in onset of clinical signs, which occur during the spring and summer months.

First Non‐Invasive Monitoring of Fecal Steroids in Greater Caribbean Manatees (Trichechus manatus manatus)

Zoo Biology, EarlyView.
This study established the first fecal hormonal reference values (P4/E2) for the Greater Caribbean manatee. Using non‐invasive ELISA, the authors found no significant differences between mature and immature females, highlighting that long‐term monitoring and ultrasounds are essential to fully understand their complex reproductive cycles.

Radioimmunoassay of unsulfated lithocholates

Journal of Lipid Research, 1977
A simple, rapid, precise radioimmunoassay for total unsulfate species of lithocholate (lithocholyglycine, lithocholyltaurine, and lithocholate) in serum is described.

Rapid hormonal rise in honey bees due to heat‐shock is mitigated by a primer pheromone

Insect Science, EarlyView.
We show that honey bee foragers increased juvenile hormone (JH) titers significantly after heat‐shocked for 1 h at 40 °C, but this increase is dependent on social conditions. Increase of JH titers only happened when bees were isolated (one worker bee per vial) but not in groups.

Radioimmunoassay of sulfated lithocholates

Journal of Lipid Research, 1977
A sensitive, rapid radioimmunoassay for sulfated species of lithocholic acid (sulfolithocholyglycine, sulfolithocholyltaurine, and sulfolithocholic acid) was developed and used to measure the total concentration of sulfated lithocholates in serum from ...

Hybrid cell lines producing monoclonal antibodies directed against Treponema [PDF]

, 1985
Continuous hybrid cell lines for producing monoclonal antibodies directed against antigens of Treponema pallidum have been developed. The hybrid cell lines were established by fusing differentiated lymphoid cells primed with antigens of Treponema ...
