The book opens by presenting an overview of modern research on the evolution and genetics of entomopathogenic fungi in Chapter One, including their function in the environment, relationship with the insect immune system, and their genetic diversity, among other things. Following this, Manuel Ruiz-Garcia, Nicolas Lichilin-Ortiz, Yolanda Mejia, Juan Manuel Ortega, and Joseph Mark Shostell discuss a study in Chapter Two where it was found that the genetic diversity levels for samples of Eira Barbara were very high. In Chapter Three, Stephen M Modell, Sharon L R Kardia, and Toby Citrin compare and contrast methods of cancer treatment for three cancer types: lung, breast, and colorectal. Anne-Sophie Pezzino, Nathalie Marec-Breton, and Agnes Lacroix review the current research on the neuropsychological profiles of persons with Williams syndrome, focusing on the heterogeneity of the observed profiles, in Chapter Four. In Chapter Five, Chun Kyu Lim presents a study on chromosome rearrangements and preimplantation genetic diagnosis. In conclusion, Chapter Six by Alan Lopez-Lopez, Miriam Margot Rivera-Angles, Carlos Alfonso Tovilla-Zarate, Roberto Molina-Solis, Araceli Valencia-Hernandez, Luis Gomez-Valencia, Thelma Beatriz Gonzalez-Castro, Isela E Juarez-Rojop, Maria Lilia Lopez-Narvaez, Ana Fresan, and Yazmin Hernandez-Diaz attempt to determine a family-based link between three polymorphisms of the brain-derived neurotrophic factor gene and attention deficit hyperactivity disorder in a Tabascan-Mexican population.
