Living with lrs

Mitochondrial polymorphisms associated with differential longevity do not impact lifetime-reproductive success.

OBJECTIVE To determine if individuals who carry mitochondrial markers which have been previously shown to affect longevity also have differential lifetime reproductive success (LRS). METHODS We extracted the mtDNA from living subjects residing in Atenas, Costa Rica. Since mtDNA does not recombine, and its probability of mutation is low, we assume that all maternal ancestors of the living subj...

Adjuvanticity of pGPL-Mc and LRS in the Immune Responses of Monkeys to Oral Immunization with Diphteria and Tetanus Toxoids

Recent controversy surrounding lipid rafts.

Lipid rafts (LRs)are highly enriched in glycosphingolipids, sphingomyelins, and cholesterol membrane microdomains, existing in a liquid-ordered phase of the plasma membrane. In the literature, LRs are also known as detergent-insoluble membranes, detergent-resistant membranes, glycosphingolipids-enriched membranes, detergent-insoluble glycolipid-rich membranes, and Triton-insoluble floating frac...

Sharing a polluted river

A river carries pollutants to people living along it if it is polluted. To make the water in the river clean, some costs are incurred. This poses a question of how to split the costs of cleaning the whole river among the agents located along it. To answer this question, we resort to the two main advocated doctrines in international disputes: the theory of Absolute Territorial Sovereignty (ATS) ...

Deciphering information encoded in birdsong: male songbirds with fertile mates respond most strongly to complex, low-amplitude songs used in courtship.

Research on the function of acoustic signals has focused on high-amplitude long-range songs (LRS) and largely ignored low-amplitude songs produced by many species during close-proximity, conspecific interactions. Low-amplitude songs can be structurally identical to LRS (soft LRS), or they can be widely divergent, sharing few spectral and temporal attributes with LRS (short-range song [SRS]). SR...
