Networks of problems: social, psychological, and genetic influences on health.

Curr Opin Psychol 2018 Nov 30;27:88-92. Epub 2018 Nov 30.

Department of Sociology, Stanford University, United States.

An emerging idea in psychopathology conceives of disorders as networks of mutually-reinforcing symptoms that constitute the disorder rather than simply reflect it. This is similar to how social scientists already view socioeconomic status, and has affinities to how physical health problems compound in later life. Social, psychological, and physical conditions might therefore be thought of as networks of problems with 'causal bridges' that span different levels and bring low SES, mental health challenges, and physical health problems into pervasive relationships with one another.

The influence of the OPRM1 (A118G) polymorphism on behavioral and neural correlates of aggression in healthy males.

Neuropharmacology 2018 Dec 12. Epub 2018 Dec 12.

Department of Psychiatry, Psychotherapy and Psychosomatics, Faculty of Medicine, RWTH Aachen University, 52074, Aachen, Germany; JARA Institute Brain Structure Function Relationship Institute for Neuroscience and Medicine (INM 10), Forschungszentrum Jülich, 52425 Jülich, Germany.

Current models of aggression suggest that in addition to personality traits and environmental factors, biological vulnerability associated with genetics substantially impacts aggressive behavior. In a functional imaging study, we investigated the influence of the single nucleotide polymorphism of the mu 1 subtype opioid receptor gene (OPRM1), implicated in sociability, on correlates of trait and state aggression to delineate the function of these influences in aggression. A key aim was further to differentiate different aspects of aggressive reactions - namely, the reaction to provocation and the decision to punish an opponent. Read More

Catecholamine Response to Exercise in Patients with Non-Obstructive Hypertrophic Cardiomyopathy.

J Physiol 2018 Dec 15. Epub 2018 Dec 15.

Division of Cardiology, Massachusetts General Hospital, 55 Fruit Street, Yawkey Suite 5B, Boston, MA, USA.

Key Points Summary: Intense physical activity, a potent stimulus for sympathetic nervous system activation, is thought to increase the risk of malignant ventricular arrhythmias among patients with hypertrophic cardiomyopathy (HCM). As a result, the majority of patients with HCM deliberately reduce their habitual physical activity after diagnosis and this lifestyle change puts them at risk for sequelae of a sedentary lifestyle; weight gain, hypertension, hyperlipidemia, insulin resistance, coronary artery disease and increased morbidity and mortality. We show that plasma catecholamine levels remain stably low at exercise intensities below the ventilatory threshold, a parameter that can be defined during cardiopulmonary exercise testing, but rise rapidly at higher intensities of exercise.

Nematic liquid crystals of bifunctional patchy spheres.

Eur Phys J E Soft Matter 2018 Dec 6;41(12):141. Epub 2018 Dec 6.

Dipartimento di Fisica, "Sapienza" Università di Roma, P.le A. Moro 2, 00185, Roma, Italy.

Anisotropic interactions can bring about the formation, through self-assembly, of semi-flexible chains, which in turn can give rise to nematic phases for suitable temperatures and concentrations. A minimalist model constituted of hard cylinders decorated with attractive sites has been already extensively studied numerically. Simulation data shows that a theoretical approach recently proposed is able to properly capture the physical properties of these self-assembly-driven liquid crystals. Read More

Lean mass and lower limb muscle function in relation to hip strength, geometry and fracture risk indices in community-dwelling older women.

Osteoporos Int 2018 Dec 14. Epub 2018 Dec 14.

Musculoskeletal Research Unit, Translational Health Sciences, Bristol Medical School, University of Bristol, Bristol, UK.

In a population-based sample of British women aged over 70 years old, lean mass and peak lower limb muscle force were both independently associated with hip strength and fracture risk indices, thereby suggesting a potential benefit of promoting leg muscle strengthening exercise for the prevention of hip fractures in postmenopausal women.

Introduction: To investigate cross-sectional associations of lean mass and physical performance, including lower limb muscle function, with hip strength, geometry and fracture risk indices (FRIs) in postmenopausal women.

Methods: Data were from the Cohort of Skeletal Health in Bristol and Avon. Read More

Upregulation of MLK4 promotes migratory and invasive potential of breast cancer cells.

Oncogene 2018 Dec 14. Epub 2018 Dec 14.

Laboratory of Experimental Medicine, Centre of New Technologies, University of Warsaw, Warsaw, Poland.

Metastasis to distant organs is a major cause for solid cancer mortality, and the acquisition of migratory and invasive phenotype is a key factor in initiation of malignancy. In this study we investigated the contribution of Mixed-Lineage Kinase 4 (MLK4) to aggressive phenotype of breast cancer cells. Our TCGA cancer genomic data analysis revealed that amplification or mRNA upregulation of MLK4 occurred in 23% of invasive breast carcinoma cases. Read More

Along-shelf connectivity and circumpolar gene flow in Antarctic silverfish (Pleuragramma antarctica).

Sci Rep 2018 Dec 14;8(1):17856. Epub 2018 Dec 14.

Department of Biology, University of Padua, Via G. Colombo 3, Padua, 35121, Italy.

The Antarctic silverfish (Pleuragramma antarctica) is a critically important forage species with a circumpolar distribution and is unique among other notothenioid species for its wholly pelagic life cycle. Previous studies have provided mixed evidence of population structure over regional and circumpolar scales. The aim of the present study was to test the recent population hypothesis for Antarctic silverfish, which emphasizes the interplay between life history and hydrography in shaping connectivity.
