Cyclic or fluctuating populations experience regular periods of low population density.Genetic bottlenecks during these periods could give rise to temporal or spatial genetic differentiation of populations.High levels of movement among increasing populations, however, could ameliorate any differences and could also synchronize the dynamics of geogr
Two new species monogenean, found in gills of marine fish from the north easter cost of Venezuela are described: Kannaphalus mochimae found in Acanthurus coeruleus (Acanthuridae) and Allopyragraphorus marinae found in Strongylura marina (Belonidae).K.mochimae differs from K.virilis Unnithan, 1957 rod seat adjustment in shaped and location of the ge
Acetate is an economical and environmental-friendly alternative carbon source.Herein, the potential of harnessing Corynebacterium glutamicum as a host to produce 3-hydroxypropionic acid (3-HP) from acetate was explored.First, the expression level of malonyl-CoA reductase from Chloroflexus aurantiacus was optimized through several strategies, strain
Anaplastic lymphoma kinase (ALK) is validated as a therapeutic molecular target in multiple malignancies, such as non-small cell lung cancer (NSCLC).However, the feasibility of targeted therapies exerted by ALK inhibitors is inevitably hindered Cooking Systems owing to drug resistance.The emergence of clinically acquired drug mutations has become a
Based on individual variation in cooperative inclinations, we define Volleyball Net the "hard problem of cooperation" as that of achieving high levels of cooperation in a group of non-cooperative types.Can the hard problem be solved by institutions with monitoring and sanctions? In a laboratory experiment we find that the answer is affirmative if t
