In a Modular High Temperature Gas Reactor (MHTGR), the Depressurized Conduction Cooldown (DCC) event can be separated into three distinct stages: 1) depressurization, 2) air ingress and, 3) natural circulation. During normal operations, the HTGR utilizes forced convection to move the helium coolant through the reactor core. Thus, during normal...
As the aging population continues to grow worldwide, age-related complications are becoming more apparent within the aging population. One of the first age-related complications to become apparent is age-associated memory impairment and it can make the elderly more dependent on caregivers early on. The N-methyl-D-aspartate (NMDA) receptor is important to...
Alzheimer’s Disease (AD) is an abnormal part of aging that mainly affects those over the age of 65. The current therapies are only FDA approved for mild to moderate AD symptoms. Cannabidiol (CBD) is a non-intoxicating constituent of Cannabis sativa that has been shown to have beneficial effects on cancer,...
This study applied a virtual rendition of the Morris water maze, which is commonly used for assessing spatial memory in rodents, to an examination of age-related differences in spatial learning among 42 younger (18-30 years) and older (>60 years) male human participants. Virtual Morris water maze performance was measured by...
As the aging population continues to grow the world over, age related complications become more and more apparent among the elderly population. One such complication is age associated memory impairment, which makes the elderly more dependent on caregivers early on. NMDA receptors in the brain are important for memory formation,...

Memory is essential to everyday life. As we age, deficits in memory become apparent. The toll of age-related cognitive impairment can be devastating to families and costly to society. The NMDA receptor is a molecule in the brain that is instrumental in the formation of memories. The receptor is particularly...
Llamas (Lama glama) appear to have predisposing anatomical features for developing
otitis media such as a long and narrow external acoustic meatus and a trabecular
tympanic bulla. However, there is limited information available about the morphology of
the ear in this species. The aim of this study was to evaluate...
Radiation exposure to the brain can occur from a variety of events, including space missions, nuclear accidents, and clinical treatments. The effects of high dose radiation are well studied, but those of lower dosage are more elusive. Decline of memory and cognition is observed in patients exposed to low dose...
Gut-brain communication consists of bidirectional routes between cognitive centers of the brain and peripheral intestines. This bidirectional communication is the result of the interplay between enteroendocrine cells (EECs), enteric nervous system, central nervous system, the vagus nerve, and our microbiota. Multiple studies have associated gut microbial dysbiosis with neurological disorders...
Age-related diseases have been associated with chronic inflammation and impaired immune response, one of the hallmarks of aging. Aging individuals also have a higher susceptibility to zinc deficiency. The effects of zinc deficiency share many commonalities with the effects of aging on the immune system and zinc deficiency may be...
