Evidence materials in a presumed suicide case were studied by a firearm examiner and a forensic chemist. The victim's body with double gunshot wounding in his forehead, a machine gun in the sustained fire mode with a silencer, and four cartridge cases were found. Examinations of the evidence, the case file studies, and experiments dedicated to the case were carried out. Relationships between the placement of cartridge cases and the gun were established using a fast camera. The distributions of gunshot residues on the evidence materials and within the comparative gunshot patterns were studied by means of optical and electron microscopy, X-ray microanalysis, and infrared spectroscopy...

Americans are the world's best armed citizens and public polling suggests protection/self-defense is their main reason for gun ownership. However, there is virtually no psychological research on gun ownership. The present article develops the first psychological process model of defensive gun ownership-specifically, a two-component model that considers both the antecedents and consequences of owning a gun for protection/self-defense. We demonstrate that different levels of threat construal-the specific perceived threat of assault and a diffuse threat of a dangerous world-independently predict handgun ownership; we also show how utility judgments can explain the motivated reasoning that drives beliefs about gun rights...

Microtubule organization and dynamics are critical for key developmental processes such as cell division, elongation, and morphogenesis. Microtubule severing is an essential regulator of microtubules and is exclusively executed by KATANIN 1 in Arabidopsis In this study, we comparatively studied the proteome-wide effects in two KATANIN 1 mutants. Thus, shotgun proteomic analysis of roots and aerial parts of single nucleotide mutant fra2 and T-DNA insertion mutant ktn1-2 was carried out. We have detected 42 proteins differentially abundant in both fra2 and ktn1-2 KATANIN 1 dysfunction altered the abundance of proteins involved in development, metabolism, and stress responses...

Shot-gun next generation sequencing (NGS) on whole DNA extracted from specimens collected from mammals often produces reads that are not mapped (i.e. unmapped reads) on the host reference genome and that are usually discarded as by-products of the experiments. In this study, we mined Ion Torrent reads obtained by sequencing DNA isolated from archived blood samples collected from 100 performance tested Italian Large White pigs. Two reduced representation libraries were prepared from two DNA pools constructed each from 50 equimolar DNA samples...

Silibinin, which is derived from Silybum marianum (milk thistle), has used as a traditional remedy for liver or biliary disorders and known to have superior antioxidant activity. In addition, silibinin was recently reported to have antifungal effect related to fungal apoptosis against Candida albicans and the interest in the therapeutic effect is increasing. In this study, we found another mode of antifungal action of silibinin and its antibiofilm activity on C. albicans. To investigate influence on fungal plasma membrane, propidium iodide and bis-(1, 3-dibutylbarbituric acid) trimethineoxonol [DiBAC4 (3)] assay were primarily carried out...

The First World War was a huge tragedy for mankind, but, paradoxically, it represented a source of significant progress in a broad series of human activities, including medicine, since it forced physicians to improve their knowledge in the treatment of a large number of wounded soldiers. The use of heavy artillery and machine guns, as well as chemical warfare, caused very serious and life-threatening lesions and wounds. The most frequent causes of death were not mainly related to gunshot wounds, but rather to fractures, tetanus and septic complications of infectious diseases...

(68)Ga-labeled capsaicin using a DOTA (1,4,7,10-tetraazocyclododecane-N,N',N″,N'″-tetraacetic acid) derivative [(68)Ga-SCN-Benzyl(Bn)-DOTA-capsaicin] was studied for the diagnosis of breast cancers, such as MCF-7 and SK-BR-3. The standard compound, (69)Ga-SCN-Bn-DOTA-capsaicin, was also prepared and characterized by spectroscopic analysis. The binding affinity of (68)Ga-SCN-Bn-DOTA-capsaicin was evaluated by using breast cancer cell lines (MCF-7, SK-BR-3) and colon cancer cell (CT-26); the biodistribution was carried out by using MCF-7-bearing nude mice, after which the positron emission tomography (PET) images were obtained at different time intervals (15-120 minutes)...

The present work is a comparative assessment of the bone regeneration potentiality of bone substitutes comprised of bioactive polymer coated biphasic calcium phosphate (BCP) granules. The bone substitutes were primarily composed of multichanneled BCP granules which were coated separately with biochemical polymer coatings, namely collagen, heparin or polydopamine, using chemical methods. The morphological features and chemical structure of the granules and surface coatings were characterized by scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR) respectively...

Recently, the US Army has mandated that Soldiers must successfully complete the physically demanding tasks of their job in order to graduate from their Initial Military Training. Evaluating individual Soldiers in the field is difficult; however, simulations of these tasks may aid in the assessment of Soldiers' abilities. The purpose of this study was to determine the reliability of simulated physical Soldiering tasks relevant to Combat Arms Soldiers. Three cohorts of ∼50 Soldiers repeated a subset of eight simulated tasks four times over two weeks...

BACKGROUND: Gun theft is an important source of guns used by criminals. Yet no empirical work has focused on the characteristics of gun owners that distinguish those who have had their guns stolen from those who have not. In this study, we examine the demographics and behavioral characteristics of gun owners who report having had a gun stolen. METHODS: Data come from a nationally representative probability-based online survey conducted in April 2015, with a linked follow-up survey in November 2015 that asked gun owners about any theft of their guns in the past 5 years...

INTRODUCTION: This paper examines associations between high-risk gun carrying and substance use in emerging adults (ages 18-22). The coexistence of these high-risk behaviours in a general population of emerging adults can have disastrous consequences. METHODS: Dating it Safe is an ongoing longitudinal (2010-2016) survey of emerging adults recruited from seven high schools in five south-east Texas-area school districts (current sample n=684). Multiple logistic regression modelling was used to examine the association between past-year use of legal and illegal substances and past-year firearm carrying for a reason other than sport or hunting...
