The hematopoietic system plays roles that are crucial for survival of the host: delivery of oxygen to tissues, arrest of accidental blood leaking from blood vessels, and fending off of invading microbes by humoral, cell-mediated, and phagocytic immunity. The activity of the hematopoietic system is staggering: daily, a normal adult produces approximately 2.5 billion erythrocytes, 2.5 billion platelets, and 1 billion granulocytes per kilogram of body weight. This production is adjusted in a timely fashion to changes in actual needs and can vary from nearly none to many times the normal rate depending on needs which vary from day to day, or even minute to minute. In response to a variety of stimuli, the cellular components of the blood are promptly increased or decreased in production to maintain appropriate numbers to optimally protect the host from hypoxia, infection, and hemorrhage. How does this all happen and happen without over or under responding? There has been extraordinary growth in our understanding ofhematopoiesis over the last two decades. Occupying center stage is the pluripotent stern cell and its progeny. Hematopoietic stern cells have been characterized by their capacity for self renewal and their ability to proliferate and differentiate along multiple lineages. Few in number, the stern cell gives rise to all circulating neutrophils, erythrocytes, lymphoid cells, and platelets. In hematopoietic transplantation, the stern cell is capable of restoring long-term hematopoiesis in a lethally irradiated host.

Social Cognition in Psychosis combines current research on phenotypes, neurobiology, and existing evidence on the assessment and treatment of various forms of psychoses. The book presents various treatment options, including assessment approaches, tools and training methods that aid in the rehabilitation of patients with psychotic disorders. Social cognition is a set of psychological processes related to understanding, recognizing, processing and appropriately using social stimuli in one's environment. Individuals with psychotic disorders consistently exhibit impairments in social cognition. As a result, social cognition has been an important target for intervention, with recent efforts trying to enhance early recovery among individuals with psychotic disorders. Provides an overview of social cognition in relation to various forms of psychotic disorders Includes assessment and treatment for social cognition dysfunction in psychoses Discusses the genetics and heritability theory of social cognitive dysfunction in psychosis Defines the neurobiology of social cognitive dysfunctions
