TL;DR: In conclusion, Leydig cell tumors were associated with increased luteinizing hormone levels and pheochromocytomas were most likely related to glucose malabsorption and altered calcium homeostasis.
Journal ArticleDOI
A comparison of compliance rates with anti-vectorial protective measures during travel to regions with dengue or chikungunya activity, and regions endemic for Plasmodium falciparum malaria.

TL;DR: Compliance with skin repellent use was associated with female gender, observing mosquitoes and travelling during the rainy season, and was not associated with the risk of malaria or chikungunya/dengue at the travel destination.
Journal Article
Beta-adrenoceptor-G alpha S coupling decreases with age in rat aorta.
TL;DR: The ability of the beta AR to form the high affinity nucleotide-sensitive complex with the agonist was restored by treatment of the membranes with cis-vaccenic acid, which increases the fluidity of the membrane.
Journal ArticleDOI
Rod outer segment phosphodiesterase: Factors affecting the hydrolysis of cyclic-AMP and cyclic-GMP
TL;DR: Hydrolysis of both cGMP and cAMP is similarly affected by the stimulators and inhibitors tested, and ATP may act in this manner to control cyclic nucleotide levels in outer segments in vivo.
Journal ArticleDOI
