BACKGROUND: Empathy is a contested concept in the field of care ethics. According to its proponents, empathy is a unique way to connect with others, to understand what is at stake for them, and to help guide moral deliberation. According to its critics, empathy is biased, inaccurate or a form of projection that does not truly grasp and respect the otherness of the other, and that may be distorted by prejudices. OBJECTIVES: We aim to contribute to a better understanding of the significance of empathy in care ethics by reviewing both the functions and limitations of empathy in this field...

Evolutionary computation (EC) has been widely applied to biological and biomedical data. The practice of EC involves the tuning of many parameters, such as population size, generation count, selection size, and crossover and mutation rates. Through an extensive series of experiments over multiple evolutionary algorithm implementations and 25 problems we show that parameter space tends to be rife with viable parameters, at least for the problems studied herein. We discuss the implications of this finding in practice for the researcher employing EC...

AIM: A significant amount of data concerning maternal-fetal damage arising from the exertion of Kristeller maneuvers (KMs) or fundal pressure (FP) go unreleased due to medicolegal implications. MATERIALS AND METHODS: For this reason, the paper gathers information as to the real magnitude of litigation related to FP-induced damages and injuries. The authors have undertaken a research in order to include general search engines (PubMed-Medline, Cochrane, Embase, Google, GyneWeb) and legal databases (De Jure, Italian database of jurisprudence daily update; Westlaw, Thomson Reuters, American ruling database and Bailii, UK Court Ruling Database)...

Hunting with wire snares is rife within many tropical forest systems, and constitutes one of the severest threats to a wide range of vertebrate taxa. As for all threats, reliable monitoring of snaring levels is critical for assessing the relative effectiveness of management interventions. However, snares pose a particular challenge in terms of tracking spatial or temporal trends in their prevalence because they are extremely difficult to detect, and are typically spread across large, inaccessible areas. As with cryptic animal targets, any approach used to monitor snaring levels must address the issue of imperfect detection, but no standard method exists to do so...

With an increasing human population, medical research is pushed to progress into an era of precision therapy. Humanized mice are at the very heart of this new forefront where it is acutely required to decipher human-specific disease pathogenesis and test an array of novel therapeutics. In this review, "humanized" mice are defined as immunodeficient mouse engrafted with functional human biological systems. Over the past decade, researchers have been conscientiously making improvements on the development of humanized mice as a model to closely recapitulate disease pathogenesis and drug mechanisms in humans...

Real-time and accurate measurements of intermediate frequency signals based on microprocessors are difficult due to the computational complexity and limited time constraints. In this paper, a fast and precise methodology based on the sigma-delta modulator is designed and implemented by first generating the twiddle factors using the designed recursive scheme. This scheme requires zero times of multiplications and only half amounts of addition operations by using the discrete Fourier transform (DFT) and the combination of the Rife algorithm and Fourier coefficient interpolation as compared with conventional methods such as DFT and Fast Fourier Transform...

Background: Media report is rife with incidences of doctor-patients' conflict, and this partly is due to communication gap and unethical practices being adopted by the doctors. Our regular curriculum fails to impart any training in ethical issues in patient care. Imparting training to students in these soft-skills is the need of the hour. Aim and Objectives: To develop a module for interns in medical ethics (MIME) in patient care, validate it and pilot run the module for standardization...

Background: Phylodynamics, the study of the interaction between epidemiological and pathogen evolutionary processes within and among populations, was originally defined in the context of rapidly evolving viruses and used to characterize transmission dynamics. The concept of phylodynamics has evolved since the early 21st century, extending its reach to slower-evolving pathogens, including bacteria and fungi, and to the identification of influential factors in disease spread and pathogen population dynamics...

The recognition and reporting of stromal and vascular lesions of the lymph node is rife with difficulties including relative rarity, a lack of familiarity with lesions and the challenges of using ancillary studies appropriately. In this manuscript, we highlight a range of benign stromal and vascular abnormalities that can be identified in nodal specimens.

The speech signal is rife with variations in phonetic ambiguity. For instance, when talkers speak in a conversational register, they demonstrate less articulatory precision, leading to greater potential for confusability at the phonetic level compared with a clear speech register. Current psycholinguistic models assume that ambiguous speech sounds activate more than one phonological category and that competition at prelexical levels cascades to lexical levels of processing. Imaging studies have shown that the left inferior frontal gyrus (LIFG) is modulated by phonetic competition between simultaneously activated categories, with increases in activation for more ambiguous tokens...

Efforts to develop new therapies to combat Alzheimer's disease suffer from extraordinarily high failure rates that make it difficult to justify continued investment in the field. Although there are a number of plausible explanations for this extremely high attrition rate, one of the explanations that has received little attention is the lack of compelling data from Phase II studies for compounds that have been pushed into Phase III trials and then have failed. An analysis of publicly available data from the Phase II studies for bapineuzumab and solanezumab indicates that neither compound produced compelling evidence of drug-like behavior that would justify their progression into pivotal trials...

Although family is an essential unit of every society, many intensive care units continue to impose limitations on families' access to their loved ones. Unlimited family presence is backed both by data and the guidelines of multiple professional societies. We propose that the obligation to protect the integrity and needs of our patients and families extends past our immediate relationship to them at the bedside, and is also a societal imperative. In a society rife with implicit bias, restrictions on family visitation risk selective enforcement of these rules, and further propagate social injustice...

Marginalized youth's development occurs in contexts rife with racialized, gendered, and socioeconomic social identity threats and barriers to social mobility. An emergent line of inquiry suggests critical action-a component of critical consciousness, defined as engaging in individual or collective social action to produce social change-may bolster career development for those experiencing marginalization. Yet, the specific mechanisms underlying critical action-career development associations are not well understood...

A thorough understanding of the role of human immunodeficiency virus (HIV) intrahost evolution in AIDS pathogenesis has been limited by the need for longitudinally sampled viral sequences from the vast target space within the host, which are often difficult to obtain from human subjects. CD8+ lymphocyte-depleted macaques infected with simian immunodeficiency virus (SIV) provide an increasingly utilized model of pathogenesis due to clinical manifestations similar to those for HIV-1 infection and AIDS progression, as well as a characteristic rapid disease onset...

The pathogenic Vibrio species (V. cholerae, V. parahaemolyticus, and V. vulnificus) represent a constant threat to human health, causing foodborne and skin wound infections as a result of ingestion of or exposure to contaminated water and seafood. Recent studies have highlighted Vibrio's ability to acquire fatty acids from environmental sources and assimilate them into cell membranes. The possession and conservation of such machinery provokes consideration of fatty acids as important factors in the pathogenic lifestyle of Vibrio species...

Psychosocial benefits of activism include increased empowerment, social connectedness, and resilience. Yet sexual minority women (SMW) and transgender individuals with multiple oppressed statuses and identities are especially prone to oppression-based experiences, even within minority activist communities. This study sought to develop an empirical model to explain the diverse meanings of social justice activism situated in SMW and transgender individuals' social identities, values, and experiences of oppression and privilege...

Mayaro virus (MAYV), causative agent of Mayaro Fever, is an arbovirus transmitted by Haemagogus mosquitoes. Despite recent attention due to the identification of several cases in South and Central America and the Caribbean, limited information on MAYV evolution and epidemiology exists and represents a barrier to prevention of further spread. We present a thorough spatiotemporal evolutionary study of MAYV full-genome sequences collected over the last sixty years within South America and Haiti, revealing recent recombination events and adaptation to a broad host and vector range, including Aedes mosquito species...

Bacterial genomes are rife with orphan biosynthetic gene clusters (BGCs) associated with secondary metabolism of unrealized natural product molecules. Often up to a tenth of the genome is predicted to code for the biosynthesis of diverse metabolites with mostly unknown structures and functions. This phenomenal diversity of BGCs coupled with their high rates of horizontal transfer raise questions about whether they are really active and beneficial, whether they are neutral and confer no advantage, or whether they are carried in genomes because they are parasitic or addictive...
