Question: Question: Do workers of a drywood termite work?
Answer: Thus, in contrast to general perception where termite workers are considered equivalent to workers in Hymenoptera, the 'large immatures' of C. secundus did not behave as workers that help in raising younger siblings. This apparently is not necessary as the colony lives inside its food. These results, which are likely to be typical for wood-dwelling termites, open the possibility that large complex group living can evolve without altruistic helping and that costly altruistic helping by workers in termites evolved only as a second step.

Answer: no

Question: Question: Are endogenous sex hormones associated with subclinical atherosclerosis in menopausal women?
Answer: Estradiol and testosterone are not associated with subclinical atherosclerosis in menopausal women. A positive correlation between IMT and FSH may reflect an association between low estrogen and IMT. Abdominal fat can be an important link between androgenic levels and cardiovascular risk.

Answer: no

Question: Question: Are clinical and serum-based markers associated with death within 1 year of de novo implant in primary prevention ICD recipients?
Answer: Individuals with more comorbidities and elevation of specific serum biomarkers were at increased risk of all-cause mortality despite being deemed as having a reasonable 1-year life expectancy. A simple risk score composed of readily available clinical data and serum biomarkers may better identify patients at high risk of early mortality and improve patient selection and counseling for primary prevention ICD therapy.

Answer:
yes
