Lay Beliefs About Gender and Sexual Behavior: First Evidence for a Pervasive, Robust (but Seemingly Unfounded) Stereotype.

Psychol Sci 2021 May 4:956797620983829. Epub 2021 May 4.

Department of Psychology, Arizona State University.

Although casual sex is increasingly socially acceptable, negative stereotypes toward women who pursue casual sex remain pervasive. For example, a common trope in television, film, and other media is that women who engage in casual sex have low self-esteem. Despite robust work on prejudice against women who engage in casual sex, little empirical work has focused on the lay theories individuals hold about them. Read More

COVID-19-related coagulopathy: a review of pathophysiology and pharmaceutical management.

Cell Biol Int 2021 May 4. Epub 2021 May 4.

Department of Hematology and Blood Banking, School of Allied Medical Sciences, Shahid Beheshti University of Medical Sciences, Tehran, Iran.

December 2019 will never be forgotten in the history of medicine when an outbreak of pneumonia of unknown etiology in Wuhan, China sooner or later prompted the World Health Organization (WHO) to issue a public health warning emergency. This is not the first nor will it be the last time that a member of β-coronaviruses (CoVs) is waging a full-scale war against human health. Notwithstanding the fact that pneumonia is the primary symptom of the novel coronavirus (2019nCoV; designated as SARS-CoV-2), the emergence of severe disease mainly due to the injury of non-pulmonary organs at the shadow of coagulopathy leaves no choice, in some cases, rather than a dreadful death.

Going beyond 'regular and casual': development of a classification of sexual partner types to enhance partner notification for STIs.

Sex Transm Infect 2021 Apr 29. Epub 2021 Apr 29.

Centre for Sexual Health and HIV Research, University College London, London, UK.

Objectives: To develop a classification of sexual partner types for use in partner notification (PN) for STIs.

Methods: A four-step process: (1) an iterative synthesis of five sources of evidence: scoping review of social and health sciences literature on partner types; analysis of relationship types in dating apps; systematic review of PN intervention content; and review of PN guidelines; qualitative interviews with public, patients and health professionals to generate an initial comprehensive classification; (2) multidisciplinary clinical expert consultation to revise the classification; (3) piloting of the revised classification in sexual health clinics during a randomised controlled trial of PN; (4) application of the Theoretical Domains Framework (TDF) to identify index patients' willingness to engage in PN for each partner type.

Results: Five main partner types emerged from the evidence synthesis and consultation: 'established partner', 'new partner', 'occasional partner', 'one-off partner' and 'sex worker'. Read More

Sex Differences in Acute Alcohol Sensitivity of Naïve and Alcohol Dependent Central Amygdala GABA Synapses.

Alcohol Alcohol 2021 Apr 29. Epub 2021 Apr 29.

The Scripps Research Institute, Department of Molecular Medicine, 10550 N Torrey Pines Rd, La Jolla, CA 92037, USA.

Aims: Alcohol use disorder (AUD) is linked to hyperactivity of brain stress systems, leading to withdrawal states which drive relapse. AUD differs among the sexes, as men are more likely to have AUD than women, but women progress from casual use to binge and heavy alcohol use more quickly and are more likely to relapse into repetitive episodes of heavy drinking. In alcohol dependence animal models of AUD, the central amygdala (CeA) functions as a hub of stress and anxiety processing and gamma-Aminobutyric acid (GABA)ergic signaling within the CeA is involved in dependence-induced increases in alcohol consumption.

Arch Sex Behav 2021 Apr 27. Epub 2021 Apr 27.

Department of Human Development and Family Studies, The Pennsylvania State University, State College, PA, USA.

Although sexual experiences are normative by young adulthood, individuals continue to explore and develop their sexual behaviors and cognitions across the college years. Thus, perceived consequences of sexual experiences may change. Similarly, characteristics of sexual experiences such as partner type, alcohol use, and sexual behavior type predict perceived consequences, and these associations may change over time. Read More

Apocalypse without anxiety: the end times for a Caribbean religion.

Anthropol Med 2021 Apr 21:1-13. Epub 2021 Apr 21.

Department of Anthropology, University College London, London, UK.

Affect has not been entirely established as a casual explanation in social science. The classic academic accounts of millennial movements emphasise both a period of 'unease' in the ambient atmosphere or 'of tension' at the actual start, and then a periodic culmination of fear or extreme emotion as the movement gains a following and the prophecy accelerates so much so, that 'apocalyptic expectation' equates with 'anxiety'. In the instance examined here, a new Caribbean religion, there may well have been identified anxieties around the time of the founder's visions, but once established the group have little strong emotion, negative or otherwise, although always facing the imminent end of all things.

Mapping functional gradients of the striatal circuit using simultaneous microelectric stimulation and ultrahigh-field fMRI in non-human primates.

Neuroimage 2021 Apr 18;236:118077. Epub 2021 Apr 18.

Center for Neuroscience Imaging Research, Institute for Basic Science, Suwon, Republic of Korea; Department of Biomedical Engineering, Sungkyunkwan University, Suwon, Republic of Korea,. Electronic address:

Advances in functional magnetic resonance imaging (fMRI) have significantly enhanced our understanding of the striatal system of both humans and non-human primates (NHP) over the last few decades. However, its circuit-level functional anatomy remains poorly understood, partly because in-vivo fMRI cannot directly perturb a brain system and map its casual input-output relationship. Also, routine 3T fMRI has an insufficient spatial resolution. Read More
