Few studies have been conducted on the relationship between “outside-residing” resilience characteristics and the risk of developing drug use disorder later in life. These characteristics include responsive and caring parenting, household routines involving regular family meals and bedtime routines, social support from peers, participation in organized activities, and religious service attendance.

Many drugs are effective systemically, but slow onset of non-intravenous routes of administration may limit their clinical utility. While anesthesiologists usually have intravenous (IV) access for drug delivery, other healthcare professionals in less controlled situations such as acute crises in the emergency room, critical care settings, or urgent needs in the community, may need non-invasive drug delivery [1].

Aryl hydrocarbon receptor (AHR) was initially discovered as a cellular protein involved in the detoxification of xenobiotic compounds. Recently, Kou and Dai [1] wrote a concise review on AHR, summarizing advances in several important areas of mammalian physiology including cardiovascular, gastrointestinal, integumentary, nervous, and immunomodulatory systems. Given the importance of AHR and our increased understanding of its physiological roles, it is necessary to highlight a few key aspects of AhR in normal development and metabolic homeostasis that have not been extensively discussed.

The purpose of this document is to provide a unique white paper on the use of different anesthetic drugs and the key clinical pearls for ensuring patient safety in humans. This paper is designed to be a convenient guide that can be placed in work rooms for residents and medical school trainees to improve their learning and to provide reminders about drug-drug interactions.

Overcrowding is a growing problem that prevails in the urban areas of both developing and developed countries. It is considered as psycho-social stress that affects the behavior and physiology of individuals and societies [1]. 
Scientific awareness of overcrowding stress systematically started in the 1960s with the early experiments of John B. Calhoun using the so-called “rat utopia” and the theory of “behavioral sink” [2]. Depending on Calhoun’s experiments, connections between the model of rodent colonies and the arising problems of crowded cities were extrapolated [3].
