The reuse of waste is increasingly widespread in order to avoid the exploitation of natural resources and to reduce costs. An example of that reuse is the employment of steel slag, a by-product from the steel making process. When the steel is produced through an electric arc furnace (EAF), two types of slag are generated: black and white slag. One application rarely used for this waste is as filler in forest tracks. In this work, two forest tracks of the Basque Country (northern Spain) filled with black and white slag 19 and 35years ago, respectively, have been studied...

INTRODUCTION: Transoral robotic surgery(TORS) for the excision of oropharyngeal tumour is increasingly considered for its lower rates of postoperative complications and better functional outcomes. However, we report a case of invasive candidiasis in an immunocompetent patient with previous radiation therapy years ago who underwent TORS recently. CASE PRESENTATION: A 55year old Chinese female with previous radiation therapy for nasopharyngeal carcinoma diagnosed in 1986 underwent wide excision of a newly diagnosed oropharyngeal carcinoma with TORS...

Osteomas are benign osteogenic lesions that result from the proliferation of mature bone. Three variants are known: central, peripheral, and extraskeletal. The peripheral variant is the most common and it most frequently affects the paranasal sinuses, rarely occurring in the jaws. This article describes the case of a 33-year-old white male patient who was referred complaining of facial asymmetry. Clinical examination revealed an increase in volume at the base of the right side of the mandible, hard bony consistency and well delimited, painless to the touch, without signs of infection or intraoral alterations...

A multiyear interagency Listeria monocytogenes Market Basket Survey was undertaken for selected refrigerated ready-to-eat foods purchased at retail in four FoodNet sites in the United States. Food samples from 16 food categories in six broad groups (seafood, produce, dairy, meat, eggs, and combination foods) were collected weekly at large national chain supermarkets and independent grocery stores in California, Maryland, Connecticut, and Georgia for 100 weeks between December 2010 and March 2013. Of the 27,389 total samples, 116 samples tested positive by the BAX PCR system for L...

A 12-year-old girl presented with a history of cervical mass, and one week of throat discomfort and dyspnea. Five years ago, the patient was diagnosed as Hashimoto's thyroiditis and hyperthyroidism; she received antithyroid drug treatment, but the result was not satisfactory. B-ultrasonic showed that the size of thyroid gland was 8.1 cm×3.2 cm in the left and 8.2 cm×4.8 cm in the right. After iodine 131 combined with radiofrequency ablation (RFA) treatment, throat discomfort and recumbent breathing difficulties disappeared, and B-ultrasonic showed that the size of thyroid reduced to 2...

Ergosterol peroxide (EP; 5α,8α-epidioxy-22E-ergosta-6,22-dien-3β-ol) is a C28-sterol and a component of many medicinal mushrooms. Since its discovery nearly a century ago, many sources and biological effects of this compound have been described. Effects range from antimicrobial to cytotoxic to immunosuppressive and other activities. This review covers biological investigations of EP, its activities, and possible mechanisms of action. EP is a promising candidate for drug development and contributes to the health-promoting effects of medicinal mushrooms...

OBJECTIVE: This review of empirical literature focuses on the design of operating rooms (ORs) by investigating the physical environmental features of ORs associated with patient and staff outcomes. BACKGROUND: Many ORs built more than 30 years ago remain operational today. However, most are inadequately designed to handle the equipment, processes, and people that a contemporary OR needs to accommodate. However, the evidence base for designing ORs has been sorely lacking, and little guidance exists on how OR design can improve safety and performance outcomes...

Genomic analysis has placed the origins of two human-pathogenic fungi, the Cryptococcus gattii species complex and the Cryptococcus neoformans species complex, in South America and Africa, respectively. Molecular clock calculations suggest that the two species separated ~80 to 100 million years ago. This time closely approximates the breakup of the supercontinent Pangea, which gave rise to South America and Africa. On the basis of the geographic distribution of these two species complexes and the coincidence of the evolutionary divergence and Pangea breakup times, we propose that a spatial separation caused by continental drift resulted in the emergence of the C...

In July 2011, the observation of a massive phytoplankton bloom underneath a sea ice-covered region of the Chukchi Sea shifted the scientific consensus that regions of the Arctic Ocean covered by sea ice were inhospitable to photosynthetic life. Although the impact of widespread phytoplankton blooms under sea ice on Arctic Ocean ecology and carbon fixation is potentially marked, the prevalence of these events in the modern Arctic and in the recent past is, to date, unknown. We investigate the timing, frequency, and evolution of these events over the past 30 years...

Lots of computational predictors have been developed for fast and large-scale analysis of biological data. However, many of them were developed long time ago when training datasets or sets of input features were rather small. Consequently, the utility of these predictors in much large datasets, which are very common in nowadays, need to be examined carefully. In addition, with the rapid development of scientific research, the expectation on the prediction accuracy of computational predictors is continuously uplifting...

La "Donna di Ostuni", the Lady from Ostuni (fortified medieval city, on the southern Italian Adriatic coast) is the skeleton of "the human most ancient mother" ever found by paleoanthropologists, grave dated of 28,000 years BP. It concerns a 20-years-old woman buried with her baby in her womb estimated at 8 months gestation. To date, the cause of the maternal-fetal deaths is qualified of unknown origin. We propose that eclampsia may be a possible explanation for these deaths (mother and baby together). Eclampsia (convulsions), the curse of human births (non-existent in other mammals), has been described since writings has existed 5000 years ago in all civilisations...

Since its discovery as a major CNS-abundant protein 25 years ago, Ubiquitin C-terminal hydrolase-L1 (UCH-L1) has emerged as an important enzyme in regulating brain protein metabolism, by coupling to the proteasome pathway of protein degradation. Areas covered: UCH-L1 is implicated in both familial and sporadic Parkinson disease and other chronic neurodegenerative diseases. Also, UCH-L1 has been recently emerging as a biofluid-based biomarker for various forms of acute neurotrauma and CNS injury. Expert opinion: The loss of UCH-L1 activity coupled with the gain of proteinopathy function are linked to neurodegeneration such as Parkinsonism and Alzheimer's disease...

Facility-based, age- and residential area-matched case-control study was conducted in Sindh, Pakistan to determine association between biomass fuel use for cooking and pulmonary tuberculosis (TB). Cases were women with pulmonary TB, and controls were those suffering from other diseases. Current users of biomass fuel were at higher risk of pulmonary TB (adjusted matched odds ratio [mOR] = 3.0; 95% CI = 1.1-4.9) compared with nonusers. In comparison with former biomass users (women not using biomass for >10 years), recent biomass users (women who switched from biomass to nonbiomass ≤10 years ago), and current (lifetime) users were at a higher risk in a dose-response manner (adjusted mOR = 2...

Arcellinid testate amoebae include a wide variety of amoeboid organisms whose test (shell) varies in shape, composition and size. A decade ago, we initiated molecular phylogenetic analyses based on SSU rRNA gene sequences and a taxonomic revision of Arcellinida. However, many lineages within Arcellinida still lack molecular data, and the phylogeny of this group is largely incomplete. In this study, we obtained SSU rRNA gene sequences from seven taxa, of which six have agglutinated shell (Difflugia oblonga, D...

Greg Priest
About 540 million years ago, a rapid radiation of animal phyla radically changed the Earth's biota in a geological eye-blink. What caused this "Cambrian explosion"? Over the years, paleontologists have pointed to a wide array of different physical mechanisms as the causal "trigger" for the explosion. More recently, some paleontologists have proposed complex causal pathways to which multiple physical mechanisms are said to have contributed. Despite their variety, these answers share an assumption that a single explanation can in principle be constructed that identifies some factor or confluence of factors as the cause of the Cambrian explosion...
