Late Glacial Interstadial
The Late Glacial Interstadial (LGI) c.14,670 to c.12,890 BP represents the first pronounced warming since the end of the Last Glacial Maximum (LGM). Human populations, which had previously forced into refuge areas, gradually begin to repopulate the Northern Hemisphere's Eurasian landmass and eventually populate North America via Beringia for the first time. Evidence for its occurrence stems from two main types of analysis. The first is the use of oxygen isotope stages (OIS) gathered from stratified deep-sea sediment cores. Samples are gathered and measured for change in isotope levels to determine temperature fluctuation for given periods of time. The second is a proxy measurement, the observation of certain reappearing fauna and flora fossils that can survive only in temperate climates, thus indicating warming trends for a given geographic area. Archaeological evidence of settlement and resettlement in certain areas by humans also serve as proxy measurements. Towards the end of OIS 2 in which the Last Glacial Maximum occurs, the deep-sea sediment cores indicate a gradually warming climate, and the reappearance of certain warm-weather flora and fauna remains throughout the Northern Hemisphere correlate with that trend. The Late Glacial Interstadial was followed by a severe decline in temperatures during the Younger Dryas from c.12,890 to c.11,650 BP.

Home Care
Home care (also referred to as domiciliary care, social care, or in-home care) is supportive care provided in the home. Care may be provided by licensed healthcare professionals who provide medical treatment needs or by professional caregivers who provide daily assistance to ensure the activities of daily living (ADLs) are met. In-home medical care is often and more accurately referred to as home health care or formal care. Often, the term home health care is used to distinguish it from non-medical care, custodial care, or private-duty care which refers to assistance and services provided by persons who are not nurses, doctors, or other licensed medical personnel. For terminally ill patients, home care may include hospice care. For patients recovering from surgery or illness, home care may include rehabilitative therapies. Home health services help adults, seniors, and pediatric clients who are recovering after a hospital or facility stay, or need additional support to remain safely at home and avoid unnecessary hospitalization. These Medicare-certified services may include short-term nursing, rehabilitative, therapeutic, and assistive home health care. This care is provided by registered nurses (RNs), licensed practical nurses (LPN's), physical therapists (PTs), occupational therapists (OTs), speech language pathologists (SLPs), home health aides (HHAs) and medical social workers (MSWs) as a limited number of up to one hour visits, addressed primarily through the Medicare Home Health benefit. The largest segment of home care consists of licensed and unlicensed non-medical personnel, including caregivers who assist the individual. Care assistants may help the individual with daily tasks such as bathing, eating, cleaning the home and preparing meals. Caregivers work to support the needs of individuals who require such assistance. These services help the client to stay at home versus living in a facility. Non-medical home care is paid for by the individual or family. The term "private-duty" refers to the private pay nature of these relationships. Home care (non-medical) has traditionally been privately funded as opposed to home health care which is task-based and government or insurance funded. These traditional differences in home care services are changing as the average age of the population has risen. Individuals typically desire to remain independent and use home care services to maintain their existing lifestyle. Government and Insurance providers are beginning to fund this level of care as an alternative to facility care. In-Home Care is often a lower cost solution to long-term care facilities.

Neuropeptide Y
Neuropeptide Y (NPY) is a 36 amino-acid neuropeptide that is involved in various physiological and homeostatic processes in both the central and peripheral nervous systems. NPY has been identified as the most abundant peptide present in the mammalian central nervous system, which consists of the brain and spinal cord. It is secreted alongside other neurotransmitters such as GABA and glutamate.  In the autonomic system it is produced mainly by neurons of the sympathetic nervous system and serves as a strong vasoconstrictor and also causes growth of fat tissue. In the brain, it is produced in various locations including the hypothalamus, and is thought to have several functions, including: increasing food intake and storage of energy as fat, reducing anxiety and stress, reducing pain perception, affecting the circadian rhythm, reducing voluntary alcohol intake, lowering blood pressure, and controlling epileptic seizures.
