OBJECTIVES: Early evidence for the treatment of dental pathology is found primarily among food-producing societies associated with high levels of oral pathology. However, some Late Pleistocene hunter-gatherers show extensive oral pathology, suggesting that experimentation with therapeutic dental interventions may have greater antiquity. Here, we report the second earliest probable evidence for dentistry in a Late Upper Paleolithic hunter-gatherer recovered from Riparo Fredian (Tuscany, Italy)...

OBJECTIVE: The aim of this study was to examine the impact of seizures on persons living with epilepsy in a national, community-based setting. METHODS: The data source was the Survey of Living with Neurological Conditions in Canada (SLNCC), a cohort derived from a national population-based survey of noninstitutionalized persons aged 15 or more years. Participants had to be on a seizure drug or to have had a seizure in the past 5 years to meet the definition of active epilepsy...

Abrupt perturbations of the global carbon cycle during the early Eocene are associated with rapid global warming events, which are analogous in many ways to present greenhouse warming. Mammal dwarfing has been observed, along with other changes in community structure, during the largest of these ancient global warming events, known as the Paleocene-Eocene Thermal Maximum [PETM; ~56 million years ago (Ma)]. We show that mammalian dwarfing accompanied the subsequent, smaller-magnitude warming event known as Eocene Thermal Maximum 2 [ETM2 (~53 Ma)]...

BACKGROUND: Artificial insemination (AI) is a reproductive biotechnology that may be influenced by several factors, including the profile of the technicians and the practices used. Assessing technician's profile and their AI practices can be significant in improving AI success rate. AIM: This study aimed to know the profile and current practices used by AI technicians (AITs), to determine the success rates of AI in water buffaloes in Leyte, Samar, and Biliran from 2011 to 2015, and to evaluate the possible association between the parameters investigated...

Hymenoptera (sawflies, wasps, ants, and bees) are one of four mega-diverse insect orders, comprising more than 153,000 described and possibly up to one million undescribed extant species [1, 2]. As parasitoids, predators, and pollinators, Hymenoptera play a fundamental role in virtually all terrestrial ecosystems and are of substantial economic importance [1, 3]. To understand the diversification and key evolutionary transitions of Hymenoptera, most notably from phytophagy to parasitoidism and predation (and vice versa) and from solitary to eusocial life, we inferred the phylogeny and divergence times of all major lineages of Hymenoptera by analyzing 3,256 protein-coding genes in 173 insect species...

Red blood cell storage in the blood bank makes millions of units of available for transfusion to civilian and military recipients every year. From glass bottles to plastic bags, from anticoagulants to complex additives, from whole blood to leukocyte filtered packed red blood cells: huge strides have been made in the field of blood component processing and storage in the blood bank during the last century. Still, refrigerated preservation of packed red blood cells under blood bank conditions results in the progressive accumulation of a wide series of biochemical and morphological changes to the stored erythrocytes, collectively referred to as the storage lesion(s)...

BACKGROUND: Overweight and obesity in childhood are a major concern in developed countries. Reference growth curves are used in current practice to identify children at risk, especially at risk of overweight or obesity. National reference growth curves were published 35 years ago from children born in the 1950s to study growth from birth to adulthood. Additionally, more recent national curves exist to study birth weight and height according to gestational age. The primary objective was to describe anthropometric measurements of French children born in the 2000s and to compare them with the French references...

REVIEW
Mario Bo, Enrica Grisoglio, Enrico Brunetti, Yolanda Falcone, Niccolò Marchionni
Atrial fibrillation is more frequent in older patients, who have a higher risk of cardioembolic stroke and thromboembolism. Oral anticoagulant therapy is the standard of treatment for stroke prevention; however, under-prescription is still very common in older patients. The reasons underlying this phenomenon have not been systematically investigated, and true contraindications only partially account for it. An intimate skepticism on the real benefit-risk balance of oral anticoagulant therapy in the oldest patients seems to derive from the fact that most studies supporting it were conducted decades ago and included younger patients, with overall better functional and clinical status...

Passive air samplers were used to evaluate long-term trends and spatial distribution of trace organic compounds in Antarctica. Duplicate PUF disk samplers were deployed at six automatic weather stations in the coastal area of the Ross sea (East Antarctica), between December 2010 and January 2011, during the XXVI Italian Scientific Research Expedition. Among the investigated persistent organic compounds, Hexachlorobenzene was the most abundant, with air concentrations ranging from 0.8 to 50 pg m(-3). In general, the following decreasing concentration order was found for the air samples analyzed: HCB > PeCB > PCBs > DDTs > HCHs...

Aggressiveness criteria proposed in the scientific literature a decade ago provide a quality judgment and are a reference in the care of patients with advanced cancer, but their use is not generalized in the evaluation of Oncology Services. In this paper we analyze the therapeutic aggressiveness, according to standard criteria, in 1.001 patients with advanced cancer who died in our Institution between 2010 and 2013. The results seem to show that aggressiveness at the end of life is present more frequently than experts recommend...

Cathodoluminescence (CL) is a powerful tool for the investigation of optical properties of materials. In recent years, its combination with scanning transmission electron microscopy (STEM) has demonstrated great success in unveiling new physics in the field of plasmonics and quantum emitters. Most of these results were not imaginable even twenty years ago, due to conceptual and technical limitations. The purpose of this review is to present the recent advances that broke these limitations, and the new possibilities offered by the modern STEM-CL technique...

BACKGROUND: Substantial attention has recently been paid to the possibility of an increased risk of chronic kidney disease (CKD) in living kidney donors. It has been demonstrated that CKD patients suffer from increased oxidative stress, which have been reported to show a strong association with several clinical problems such as accelerated atherosclerosis. The purpose of the current cross-sectional, single-center study was to evaluate the relationship between renal functions of living kidney donors and systemic oxidative stress...

The International Comet Assay Workshops are a series of scientific conferences dealing with practical and theoretical aspects of the Comet Assay (single-cell gel electrophoresis)-a simple method for detecting DNA strand breaks. The first paper describing such an assay was published over 30 years ago in 1984 by Swedish researchers O. Ostling and K. J. Johanson. Appropriately, the theme for the 2015 meeting was looking to the future: 'The Next 3 Decades of the Comet Assay'. The programme included 25 oral and 43 poster presentations depicting the latest advances in technical developments as well as applications of the comet assay in genotoxicity testing (in vitro and in vivo) and biomonitoring of both humans and the environment...

Background and objectives: From the beginnings of modern orthodontics, questions have been raised about the extraction of healthy permanent teeth in order to correct malocclusions. A hundred years ago, orthodontic tooth extraction was debated with almost religious intensity by experts on either side of the issue. Sheldon Friel and his mentor Edward H. Angle both had much to say about this controversy. Today, after significant progress in orthodontic practice, similar arguments are being voiced between nonextraction expansionists and those who see the need for tooth extractions in some orthodontic patients...
