Life and mortality in Ugaritic : a lexical and literary study
\"Identifies and analyzes the Ugaritic terms most commonly used to talk about life and mortality in order to construct a more representative framework of the ancient perspective on these topics\"--Provided by publisher.
Life and mortality in Ugaritic : a lexical and literary study
2019
While topics such as death, funerary cult, and the netherworld have received considerable scholarly attention in the context of the Ugaritic textual corpus, the related concept of life has been relatively neglected. Life and Mortality in Ugaritic takes as its premise that one cannot grasp the significance of mwt (“to die”) without first having wrestled with the concept of ḥyy (“to live”).
In this book, Matthew McAffee takes a lexical approach to the study of life and death in the Ugaritic textual corpus. He identifies and analyzes the Ugaritic terms most commonly used to talk about life and mortality in order to construct a more representative framework of the ancient perspective on these topics, and he concludes by synthesizing the results of this lexical study into a broader literary discussion that considers, among other things, the implications for our understanding of the first-millennium Katumuwa stele from Zincirli.
McAffee’s study complements previous scholarly work in this area, which has tended to rely on conceptual and theoretical treatment of mortality, and advances the discussion by providing a more focused lexical analysis of the Ugaritic terms in question. It will be of interest to Semitic scholars and those who study Ugaritic in particular, in addition to students of the culture of the ancient Levant.
Essential versus accessory aspects of cell death: recommendations of the NCCD 2015
2015
Cells exposed to extreme physicochemical or mechanical stimuli die in an uncontrollable manner, as a result of their immediate structural breakdown. Such an unavoidable variant of cellular demise is generally referred to as ‘accidental cell death’ (ACD). In most settings, however, cell death is initiated by a genetically encoded apparatus, correlating with the fact that its course can be altered by pharmacologic or genetic interventions. ‘Regulated cell death’ (RCD) can occur as part of physiologic programs or can be activated once adaptive responses to perturbations of the extracellular or intracellular microenvironment fail. The biochemical phenomena that accompany RCD may be harnessed to classify it into a few subtypes, which often (but not always) exhibit stereotyped morphologic features. Nonetheless, efficiently inhibiting the processes that are commonly thought to cause RCD, such as the activation of executioner caspases in the course of apoptosis, does not exert true cytoprotective effects in the mammalian system, but simply alters the kinetics of cellular demise as it shifts its morphologic and biochemical correlates. Conversely,
bona fide
cytoprotection can be achieved by inhibiting the transduction of lethal signals in the early phases of the process, when adaptive responses are still operational. Thus, the mechanisms that truly execute RCD may be less understood, less inhibitable and perhaps more homogeneous than previously thought. Here, the Nomenclature Committee on Cell Death formulates a set of recommendations to help scientists and researchers to discriminate between essential and accessory aspects of cell death.

A review of thanatosis (death feigning) as an anti-predator behaviour
2018
Thanatosis—also known as death-feigning and, we argue more appropriately, tonic immobility (TI)—is an under-reported but fascinating anti-predator strategy adopted by diverse prey late on in the predation sequence, and frequently following physical contact by the predator. TI is thought to inhibit further attack by predators and reduce the perceived need of the predator to subdue prey further. The behaviour is probably present in more taxa than is currently described, but even within well-studied groups the precise taxonomic distribution is unclear for a number of practical and ethical reasons. Here we synthesise the key studies investigating the form, function, evolutionary and ecological costs and benefits of TI. This review also considers the potential evolutionary influence of certain predator types in the development of the strategy in prey, and the other non-defensive contexts in which TI has been suggested to occur. We believe that there is a need for TI to be better appreciated in the scientific literature and outline potentially profitable avenues for investigation. Future use of technology in the wild should yield useful developments for this field of study.

Introduction and Methods
This report summarizes the results of the first phase in the development of international guidelines for death determination, focusing on the biology of death and the dying process, developed by an invitational forum of international content experts and representatives of a number of professional societies.
Results and Conclusions
Precise terminology was developed in order to improve clarity in death discussion and debate. Critical events in the physiological sequences leading to cessation of neurological and/or circulatory function were constructed. It was agreed that death determination is primarily clinical and recommendations for preconditions, confounding factors, minimum clinical standards and additional testing were made. A single operational definition of human death was developed: ‘the permanent loss of capacity for consciousness and all brainstem functions, as a consequence of permanent cessation of circulation or catastrophic brain injury’. In order to complete the project, in the next phase, a broader group of international stakeholders will develop clinical practice guidelines, based on comprehensive reviews and grading of the existing evidence.

The idea of synergistic interactions between drugs and chemicals has been an important issue in the biomedical world for over a century. As complex diseases, especially cancer, are being treated with various drug cocktails, understanding the interactions among these drugs is increasingly vital to ensuring successful treatment regimens. However, the idea of synergy is not limited to only the biomedical realm and these ideas have developed across many different disciplines, as well. In this review, we first discuss the various terminology surrounding the idea of synergy, providing a comprehensive list of terms defined across numerous disciplines. We then review the most common methodology for detection and quantification of synergy, including the two most prominent reference models for describing additive interactions: Loewe Additivity and Bliss Independence. We also discuss advantages and limitations to each method, with a focus on the Chou-Talalay Combination Index method. Finally, we describe how methods development and terminology have developed among disciplines outside of biomedicine and pharmacology, to synthesize the literature for readers.

Purpose
Acute gastrointestinal (GI) dysfunction and failure have been increasingly recognized in critically ill patients. The variety of definitions proposed in the past has led to confusion and difficulty in comparing one study to another. An international working group convened to standardize the definitions for acute GI failure and GI symptoms and to review the therapeutic options.
Methods
The Working Group on Abdominal Problems (WGAP) of the European Society of Intensive Care Medicine (ESICM) developed the definitions for GI dysfunction in intensive care patients on the basis of the available evidence and current understanding of the pathophysiology.
Results
Definitions for acute gastrointestinal injury (AGI) with its four grades of severity, as well as for feeding intolerance syndrome and GI symptoms (e.g. vomiting, diarrhoea, paralysis, high gastric residual volumes) are proposed. AGI is a malfunctioning of the GI tract in intensive care patients due to their acute illness. AGI grade I = increased risk of developing GI dysfunction or failure (a self-limiting condition); AGI grade II = GI dysfunction (a condition that requires interventions); AGI grade III = GI failure (GI function cannot be restored with interventions); AGI grade IV = dramatically manifesting GI failure (a condition that is immediately life-threatening). Current evidence and expert opinions regarding treatment of acute GI dysfunction are provided.
Conclusions
State-of-the-art definitions for GI dysfunction with gradation as well as management recommendations are proposed on the basis of current medical evidence and expert opinion. The WGAP recommends using these definitions for clinical and research purposes.

Sudden Infant Death Syndrome on Facebook: Qualitative Descriptive Content Analysis to Guide Prevention Efforts
2020
Sudden unexpected infant death (SUID), which includes the diagnosis of sudden infant death syndrome (SIDS), is a leading cause of infant mortality in the United States. Despite prevention efforts, many parents continue to create unsafe infant sleep environments and use potentially dangerous infant sleep and monitoring devices, ultimately leading to sleep-related infant deaths. Analyzing Facebook conversations regarding SIDS may offer a unique maternal perspective to guide future research and prevention efforts.
This study aims to describe and analyze conversations among mothers engaged in discussions about SIDS on a Facebook mother's group. We were interested in understanding maternal knowledge of SIDS, identifying information sources for SIDS, describing actual infant sleep practices, exploring opinions regarding infant sleep products and monitoring devices, and discovering evidence of provider communication regarding SIDS.
We extracted and analyzed 20 posts and 912 comments from 512 mothers who participated in a specific Facebook mother's group and engaged in conversations about SIDS. There were 2 reviewers who coded the data using qualitative descriptive content analysis. Themes were induced after discussion among researchers and after the study objectives were addressed.
The theme of social support emerged, specifically informational and emotional support. A variety of informational sources for SIDS and safe sleep were identified, as was a continuum of infant sleep practices (ranging from unsafe to safe sleep per the American Academy of Pediatrics standards). There was widespread discussion regarding infant sleep products and monitoring devices. Embedded within conversations were (1) confusion among commonly used medical terminology, (2) the practice of unsafe infant sleep, (3) inconsistency in provider communication about SIDS, and (4) maternal anxiety regarding SIDS.
We uncovered new findings in this analysis, such as the commonality of infant sleep products and monitoring devices and widespread maternal anxiety regarding SIDS. Additionally, mothers who participated in the Facebook group provided and received informational and emotional support regarding SIDS via this social media format. Such results can guide future prevention efforts by informing health communication regarding SUID and safe sleep. Future provider and public health agency communication on the topic of SUID and safe sleep should be simple and clear, address infant sleep products and monitoring devices, address maternal anxiety regarding SIDS, and address the common practice of unsafe sleep.

Autophagic cell death: the story of a misnomer
2008
The question of whether cell death can occur by autophagy cannot yet be answered definitively, although the occurrence of cell death with autophagy is common. The term autophagic cell death should therefore be considered a misnomer until this issue has been resolved.
Dying cells often display a large-scale accumulation of autophagosomes and hence adopt a morphology called autophagic cell death. In many cases, it is agreed that this autophagic cell death is cell death with autophagy rather than cell death by autophagy. Here, we evaluate the accumulating body of literature that argues that cell death occurs by autophagy. We also list the caveats that must be considered when deciding whether or not autophagy is an important effector mechanism of cell death.

Words matter: ‘enduring intolerable suffering’ and the provider-side peril of Medical Assistance in Dying in Canada
2025
Enduring intolerable suffering, an essential eligibility criterion in Medical Assistance in Dying (MAiD) in Canada and elsewhere, is a contradiction in terms, in that suffering must be tolerable to be endured. Cases of people who were approved for MAiD but who elected to die naturally, thus tolerating their suffering, bear out the unreliability of this central safeguard. The clinical assessment of intolerable suffering may be strengthened by adopting a definition of intolerable suffering centred on clinically evidenced physical and psychological decompensation. This argument also raises important questions about the risks of MAiD clinicians subjectively defining, approving and providing MAiD in ways that deviate from accepted legal and clinical concepts and ethics. Examples show some prolific clinicians describe MAiD in terminology that differs from such norms, as a personal mission, as personally pleasurable, and as a rights-based service. These alternative views are explored for their risks in assessing and providing MAiD for intolerable suffering. This further demonstrates the need for conceptual clarity in legislation, improved vetting and monitoring of clinicians, and a different assessment process to protect patients and clinicians.
