Circulating cell-free mitochondrial DNA levels and glucocorticoid sensitivity in a cohort of male veterans with and without combat-related PTSD

Circulating cell-free mitochondrial DNA (ccf-mtDNA) is a biomarker of cellular injury or cellular stress and is a potential novel biomarker of psychological stress and of various brain, somatic, and psychiatric disorders. No studies have yet analyzed ccf-mtDNA levels in post-traumatic stress disorder (PTSD), despite evidence of mitochondrial dysfunction in this condition. In the current study, we

Tuning Pluronic F127 phase transitions by adding physiological amounts of salts : A rheology, SAXS, and NMR investigation

Specific ion (Hofmeister) effects in colloid and biological systems represented a scientific challenge for more than 100 years. Recently, possible applications, based on their rationalization, are emerging. Here, Cl-, SO42-, SCN- anions and Na+, K+, Mg2+ cations are added at physiological concentration (∼0.15 mol/kg) to Pluronic F127 20 wt% aqueous solutions to suitably tune phase transitions for

We need to talk about 'bad' resilience

In this analysis, we argue against seeing health system resilience as an inherently positive concept. The rise in the popularity of health system resilience has led to its increasingly normative framing. We question this widely accepted perspective by examining the underlying assumptions associated with this normative framing of 'good' resilience. Our focus is on the risks of accepting the assumpt

Delivery of a sebum modulator by an engineered skin microbe in mice

Microorganisms can be equipped with synthetic genetic programs for the production of targeted therapeutic molecules. Cutibacterium acnes is the most abundant commensal of the human skin, making it an attractive chassis to create skin-delivered therapeutics. Here, we report the engineering of this bacterium to produce and secrete the therapeutic molecule neutrophil gelatinase-associated lipocalin,

Simultaneous shape and topology optimization of inflatable soft robots

Simultaneous shape and topology optimization is used to design pressure-activated inflatable soft robots. The pressure loaded boundary is meshed conformingly and shape optimized, while the morphology of the robot is topology optimized. The design objective is to exert maximum force on an object, i.e. to produce soft “grippers”. The robot's motion is modeled using nearly incompressible finite defor

Comparative analysis and optimisation of hydrogen combustion mechanism for laminar burning velocity calculation in combustion engine modelling

Hydrogen stands out as a compelling alternative to fossil fuels for combustion engines. Predictive combustion models are instrumental in developing hydrogen-fuelled engines. A fundamental metric of these models is the laminar burning velocity (LBV), which can be precisely determined through laminar flame propagation simulations. In this context, the selection of an appropriate combustion mechanism

Density affects plant size in the Gobi Desert

Plant size is a crucial functional trait with substantial implications in agronomy and forestry. Understanding the factors influencing plant size is essential for ecosystem management and restoration efforts. Various environmental factors and plant density play significant roles in plant size. However, how plant size responds to mean annual precipitation (MAP), mean annual temperature (MAT), and d

Emerging role of microRNAs as regulators of protein kinase C substrate MARCKS and MARCKSL1 in cancer

MicroRNAs (miRNAs) have emerged as pivotal regulators of gene expression, playing essential roles in diverse cellular processes, including the development and progression of cancer. Among the numerous proteins influenced by miRNAs, the MARCKS/MARCKSL1 protein, a key regulator of cellular cytoskeletal dynamics and membrane-cytosol communication, has garnered significant attention due to its multifa

Prevalence and incidence of diabetes mellitus : a nationwide population-based pharmaco-epidemiological study in Sweden

AIM: To investigate the changes in prevalence and incidence of pharmacologically and non-pharmacologically treated diabetes in Sweden during 2005 to 2013.METHODS: We obtained data on gender, date of birth and pharmacologically and non-pharmacologically treated diabetes from national registers for all Swedish residents.RESULTS: During the study period a total of 240 871 new cases of pharmacological

Causes and circumstances of death in stimulant and opioid use-A comparative study

AIMS: To investigate the individual characteristics, causes and circumstances around deaths in stimulant use, and to examine how individuals who died with stimulants in their body differ from individuals who died with opioids in their body.METHODS: This study includes individuals who died during the years 2000-2018 and underwent a forensic autopsy at Forensic Medicine in Lund, Skåne County, Sweden

Agent-Based Life Cycle Assessment enables joint economic-environmental analysis of policy to support agricultural biomass for biofuels

Production of agricultural biofuels is expected to rise due to increasing climate change mitigation ambitions. Policy interventions promoting targeted bioenergy solutions can be motivated by the large environmental externalities present in agricultural systems and the local context of biomass production co-benefits. Introducing energy crops in crop rotations in arable land with depleted Soil Organ

Keeping it in the family: Reproduction beyond genetic parenthood

Recent decades have seen the facilitation of unconventional or even extraordinary reproductive endeavours. Sperm has been harvested from dying or deceased men at the request of their wives; reproductive tissue has been surgically removed from children at the request of their parents; deceased adults´ frozen embryos have been claimed by their parents, in order to create grandchildren; wombs have be

Tomorrowland : Critical Social Theory of Planetary Politics

We live in ‘Tomorrowland’; a land at the nexus of social science and natural science where the solution to our problems will be found tomorrow. The paper addresses the impossibility of international relations by proposing an alternative approach located in critical social theory. The paper utilises critical social theory to critique contemporary liberal assumptions and rationalisations of cultures
