Forensic age estimation research based on skeletal structures focuses on patterns of growth and development using different bones. In this work, our aim was to study growth-related evolution of the manubrium in living adolescents and young adults using magnetic resonance imaging (MRI), which is an image acquisition modality that does not involve ionizing radiation. In a first step, individual manubrium and subject features were correlated with age, which confirmed a statistically significant change of manubrium volume (Mvol:p<0...

An extensive body of research theorises that attachment to place is positively associated with health, particularly for older people. Building on this, we measure how indicators of attachment to place are associated with health for in people of advanced age in New Zealand. We use data from a cohort study (LiLACS NZ), which includes an indigenous Māori cohort aged 80-90 years and a non-Māori cohort aged 85 years from a mixed urban/rural region in New Zealand. Each cohort undertook a comprehensive interview and health assessment (n = 267 Māori and n = 404 non-Māori)...

Long noncoding RNAs (lncRNAs), as new class of functional regulators involved in human tumorigenesis, have been attracting increasing attention of researchers. The lncRNA Colorectal Neoplasia Differentially Expressed (CRNDE), transcribed from chromosome 16 on the strand opposite to the adjacent IRX5 gene, were originally found to be increased in CRC and was reported abnormal expressed in many cancers. However, its potential role and molecular mechanism underlying radioresistant phenotype formation of lung adenocarcinoma (LAD) remains unclear...

Geoff Hollis
Best-worst scaling is a judgment format in which participants are presented with a set of items and have to choose the superior and inferior items in the set. Best-worst scaling generates a large quantity of information per judgment because each judgment allows for inferences about the rank value of all unjudged items. This property of best-worst scaling makes it a promising judgment format for research in psychology and natural language processing concerned with estimating the semantic properties of tens of thousands of words...

Alexandra Ernst, Arnaud D'Argembeau
While the cognitive and neural bases of episodic future thinking are well documented, questions remain as to what gives the sense that an imagined event belongs to one's personal future. Capitalizing on previous research on metacognitive appraisals in autobiographical remembering, we propose that episodic future thinking involves, in varying degrees, a subjective belief in the potential occurrence of imagined future events and we explore the nature and determinants of such belief. To this aim, participants provided justifications for belief in occurrence for a series of past and future events...

Functional Magnetic Resonance Imaging (fMRI) is at present one of the most used methodologies for functional brain exploration, both in clinical and research settings. fMRI can noninvasively measure neural activity by using specific experimental paradigms. Often, these paradigms require the stimulation of the subject to perform sensorimotor tasks: in the past, the stimuli have been administered manually for investigating fundamental aspects of tactile perception and somatosensory processing. Nowadays, the use of mechatronic devices to stimulate the subject during fMRI studies is growing, also to assure reproducibility, control, and monitoring of task performances...

REVIEW
Genrich Tolstonog, Christian Simon
The task of surgical research is to improve the efficacy of available surgical therapeutic modalities, develop new ones, and balance this well with favorable functional outcome. Therefore, surgical research is composed of a translational and a clinical component. In translational surgical research, animal models are used to better understand the biology of head and neck cancers, but even more importantly, the biology of changes to the disease and the microenvironment created by surgical interventions. Animal models additionally allow for the development of image-guided surgery systems, novel strategies of intraoperative adjuvant treatment, and patient "avatars" to test innovative anticancer drug combinations...

In Ghana, men who have sex with men (MSM) bear a high burden of HIV. Identifying factors that influence engagement in HIV care among HIV-infected Ghanaian MSM is critical to devising novel interventions and strengthening existing programs aimed at improving outcomes across the HIV care continuum. Consequently, we conducted an exploratory qualitative research study with 30 HIV-infected Ghanaian MSM between May 2015 and July 2015. Common barriers were fear of being seen in HIV-related health facility, financial difficulties, and health system challenges...

The pleiotropic functions of circulating high density lipoprotein (HDL) on peripheral vascular health are well established. HDL plays a pivotal role in reverse cholesterol transport and is also known to suppress inflammation, endothelial activation and apoptosis in peripheral vessels. Although not expressed in the central nervous system, HDL has nevertheless emerged as a potential resilience factor for dementia in multiple epidemiological studies. Animal model data specifically support a role for HDL in attenuating the accumulation of β-amyloid within cerebral vessels concomitant with reduced neuroinflammation and improved cognitive performance...

When poliomyelitis is totally eradicated from the natural world containment will be vital to prevent its re-emergence. The matter has become pressing as type 2 component of oral polio vaccine was completely withdrawn by May 2016 as wild ty[e 2 was declared eradicated. Work on polioviruses must be contained in accordance with GAPIII (the third version of the Global Action Plan of WHO). Some activities will be essential for years after eradication. Vaccine production and control, surveillance and supportive applied and academic research must all continue...

REVIEW
Rajko Igić
This review offers a contemporary history of the renin-angiotensin (RAS) and kallikrein-kinin (KKS) systems with emphasis on how these complex systems affect the eye. It describes the types of communication (cross-talk) between the two systems and evaluates their potential role in the development of diabetic retinopathy, diabetic macular edema, age-related macular degeneration, glaucoma, and uveitis. In addition to detailing the important physiological actions of components of the RAS and KKS, possibilities are suggested for new therapeutic avenues in the treatment of common ocular diseases...

The natural product artemisinin and derivatives thereof are currently considered as the drugs of choice for the treatment of malaria. At the same time, a significant number of such drugs have also shown interesting anticancer activity. In the context of the present research work, artemisinin was structurally modified and anchored to naturally occurring polyamines to afford new artemisinin dimeric conjugates whose potential anticancer activity was evaluated. All artemisinin conjugates tested were more effective than artemisinin itself in decreasing the number of MCF7 breast cancer cells...

There is a rising interest in snake venoms proteins (SVPs) because these macromolecules are related to pharmacological properties that manifest themselves during poisoning and can lead to secondary microbial infections. Interestingly, researchers have somehow neglected the antimicrobial activity of SVPs. The aims of this study were: (i) to verify whether the venom of the Peruvian snake Bothriopsis oligolepis displays such activity; (ii) to isolate and identify some its antimicrobial constituents. Liquid growth inhibition assays revealed that the crude venom inhibited the growth of Gram-positive and Gram-negative bacteria, but not of Candida species...

Southeastern states namely Georgia, Florida, and Alabama produce two-thirds of the peanuts in the United States. Thrips-transmitted Tomato spotted wilt virus (TSWV), which causes spotted wilt disease, has been a major impediment to peanut production for the past three decades. The cultivars grown in the 1980s were extremely susceptible to TSWV. Early yield losses extended to tens of millions of dollars each year (up to 100% loss in many fields). This situation led to the creation of an interdisciplinary team known as "SWAT: Spotted Wilt Action Team"...

Research on emotional eating mostly focuses on negative emotions. Much less is known about how positive emotions relate to overeating and binge eating (BE). The aim of the current study was to construct a scale for positive and negative emotional eating and to assess its predictive validity. In study 1, the Positive-Negative Emotional Eating Scale (PNEES) was constructed and tested on 531 women, who also completed Eating Disorders Assessment Scale (EDAS). Results showed that a two-factor model constituting Positive emotional eating (PNEES-P) and Negative emotional eating (PNEES-N) fit the data well...

REVIEW
Alison Colquhoun
The renewed interest in cancer metabolism in recent years has been fuelled by the identification of the involvement of key oncogenes and tumour suppressor genes in the control of metabolic pathways. Many of these alterations lead to dramatic changes in bioenergetics, biosynthesis and redox balance within tumour cells. The complex relationship between tumour cell metabolism and the tumour microenvironment has turned this field of biochemistry and cell biology into a challenging and exciting area for study. In the case of gliomas the involvement of altered metabolic pathways including glycolysis, oxidative phosphorylation and glutaminolysis are pointing the way to new possibilities for treatment...
