Abstract:
In this chapter, we develop a model of μ- and δ-opioid receptor (OR) effects on cellular activity in the corticostriatal circuit after reviewing clinical data on cognitive and mood impairments in opioid substance use disorder (OUD), we use this model to derive information on the relevance of opioid actions in this circuit for cognition and reward. We find that the cognitive impairments and rewarding properties of acute μ-OR activation can reasonably explained by pharmacological actions in the corticostriatal circuit. However, long-term cognitive impairments and mood dysfunction observed in OUD are probably induced by opiate abuse-related degenerative mechanisms.

Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
Disorders of Erythrocytes
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.
On the other...
Disorders of Leukocytes
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune...
