Environmental variation experienced during early periods of development can lead to persistent phenotypic alteration, known as carryover effects. Such effects increase concern for threatened or endangered species such as the white sturgeon (Acipenser transmontanus), particularly considering expected thermal changes due to climate change. We evaluated how temperature during embryonic development affects physiological parameters such as larval and early juvenile growth and thermal tolerance.

Article Synopsis
  • The study aimed to compare direct vs. indirect revascularization methods for the left vertebral artery in patients needing surgery involving the aortic arch.
  • It found that patients undergoing direct revascularization had higher rates of complications like stroke, death, and nerve injuries compared to those with indirect revascularization via the subclavian artery.
  • Results showed that direct revascularization patients were almost three times more likely to experience severe outcomes and six times more likely to have issues like hoarseness post-surgery.

Phasic dopamine activity is believed to both encode reward-prediction errors (RPEs) and to cause the adaptations that these errors engender. If so, a rat working for optogenetic stimulation of dopamine neurons will repeatedly update its policy and/or action values, thus iteratively increasing its work rate. Here, we challenge this view by demonstrating stable, non-maximal work rates in the face of repeated optogenetic stimulation of midbrain dopamine neurons.

Individuals vary in their immune genotype, inbreeding coefficient f, immune responses, survival to adulthood, and adult longevity. However, whether immune genes predict survival or longevity, whether such relationships are mediated through immune responses, and how f affects immune genotype remain unclear. We use a wild song sparrow (Melospiza melodia) population in which survival to adulthood, adult longevity, and f were measured precisely, and in which immune responses have previously been assessed.

Common conceptions of spirituality in nursing often concentrate on nurses providing spiritual care, but there is insufficient research indicating how nurses' spirituality impacts their nursing practice. This study examines how Indigenous and non-Indigenous community health nurses' experiences of spirituality, regardless of any religious affiliation, shape their nursing practice with Indigenous communities. Results indicate that spirituality is a pervasive nursing ethic manifesting respect, connectedness, love, acceptance, caring, hope, endurance, and compassion toward clients.

Both inter- and intragroup interactions can be important influences on behaviour, yet to date most research focuses on intragroup interactions. Here, we describe a hitherto relatively unknown behaviour that results from intergroup interaction in the cooperative breeding pied babbler: kidnapping. Kidnapping can result in the permanent removal of young from their natal group.

Physician Authority, Family Choice, and the Best Interest of the Child.

Camb Q Healthc Ethics

January 2022

Department of Philosophy, Langara College, Vancouver, British ColumbiaV6M 2J2, Canada.

Two of the most poignant decisions in pediatrics concern disagreements between physicians and families over imperiled newborns. When can the family demand more life-sustaining treatment (LST) than physicians want to provide? When can it properly ask for less? The author looks at these questions from the point of view of decision theory, and first argues that insofar as the family acts in the child's best interest, its choices cannot be constrained, and that the maximax and minimax strategies are equally in the child's best interest. He then proposes a guideline according to which the family can demand LST if it is physiologically possible to preserve a life the child can be expected to welcome, and refuse such treatment if it causes suffering that is "more than can be borne" even if an uncompromised life is expected to emerge.

Many species maintain territories, but the degree of overlap between territories and the level of aggression displayed in territorial conflicts can vary widely, even within species. Greater territorial overlap may occur when neighboring territory holders are close relatives. Animals may also differentiate neighbors from strangers, with more familiar neighbors eliciting less-aggressive responses during territorial conflicts (the "dear enemy" effect).

Multiphoton microscopy is one of several new technologies providing unprecedented insight into the activity dynamics and function of neural circuits. Unfortunately, some of these technologies require experimentation in head-restrained animals, limiting the behavioral repertoire that can be integrated and studied. This issue is especially evident in drug addiction research, as no laboratories have coupled multiphoton microscopy with simultaneous intravenous drug self-administration, a behavioral paradigm that has predictive validity for treatment outcomes and abuse liability.

Introduction: Emergency departments (EDs) at public hospitals in Vietnam typically face problems with overcrowding, as well as being populated by a wide variety of illnesses, resulting in increasing dissatisfaction from patients. To alleviate these problems, we used the increasingly popular value-stream mapping (VSM) and lean strategy approaches to (1) evaluate the current patient flow in EDs; (2) identify and eliminate the non-valued-added components; and (3) modify the existing process in order to improve waiting times.

Methods: Data from a total of 742 patients who presented at the ED of 108 Military Central Hospital in Hanoi, Vietnam, were collected.

The construct of a Balanced Time Perspective (BTP) predicts a variety of indices of mental health and well-being. We argue that one possible intermediate link between BTP and well-being may be an individual's sense of presence of meaning in life. Participants ranging in age from 19 to 88 years (N = 192) completed two measures of time perspective (Zimbardo Time Perspective Inventory [ZTPI] and the modified Balanced Time Perspective Scale [mBTPS]), mental health, personality, and meaning in life.
