WebbThe median survival time with pemetrexed was significantly higher than with other chemotherapies (13 versus 7 months, P=0.006). In multivariate analysis, the prognosis was significantly correlated with treatment modality (P=0.000), Karnofsky performance status (P=0.000), number of brain metastases (P=0.001), and histologic tumor type (P=0.007).

WebbThe koala has one of the lowest ratios of brain to body mass of any mammal. Even though koalas are dumb, they have survived because their brains use minimal energy. Using the least amount of energy possible appears to be a key adaptation to surviving on a nutritionally poor, low energy diet of toxic eucalyptus leaves. Webb22 maj 2024 · Let us take imaginary brains in our hands again, this time two primate brains, one twice the size of the other. How many neurons would the larger one have? Well, in this case, about twice the number of neurons of the smaller brain. Now, if brains were all built in the same way, with the same uniform recipes, we would see the same thing in … closeout spinning reels on sale

We studied dolphin brains varying from 783 to 6215g. As expected, average neuron density in four areas of cortex decreased from the smallest to the largest brain. Despite having a lower neuron density than smaller … WebbBEAR INTELLIGENCE. The thing about bears that perhaps fascinates people the most is their remarkable intelligence. They are the most intelligent native nonhuman animals in North America, and many modern bear biologists accredit them with the equivalent IQ of the great apes, some even dare give them the equivalent intelligence of a 3-year-old … closeout sorel winter boots women\u0027s
