Introduction: Granular cell tumors (GCTs) are of neuroectodermal origin and account for 0.5% of soft tissue tumors. They are most prevalent in African-Americans in the fourth to sixth decades, with a predilection for the head and neck regions. GCTs usually resemble more common lesions and hence are difficult to diagnose preoperatively. The tumor is readily identified on needle biopsy. Although usually benign with a malignancy rate of only 2-3%, the malignant form has a reported 3-yr mortality of 60%...

BACKGROUND: Most of the available literature on ST-Elevated myocardial infarction (STEMI) in women was conducted in the developed world and data from Middle-East countries was limited. AIM: To examine the clinical presentation, patient management, quality of care, risk factors and in-hospital outcomes of women with acute STEMI compared with men using data from a large STEMI registry from the Middle East. METHODS: Data were derived from the third Gulf Registry of Acute Coronary Events (Gulf RACE-3Ps), a prospective, multinational study of adults with acute STEMI from 36 hospitals in 6 Middle-Eastern countries...

In this anatomy report, we describe the first case of abducens nerve duplication limited to the sphenopetroclival venous gulf and the cavernous sinus. The objective point of division of the two duplicated roots was localized at the gulfar face of the dural porus, just distal to the unique cisternal trunk of the abducens nerve, as it pierced the petroclival dural mater. In the gulfar segment, both roots traveled through a variant of Dorello's canal called the "petrosphenoidal canal" and remained separated through the posterior half of the cavernous sinus...

Six velocity sections straddling Cape Hatteras show a deep counterflow rounding the Cape wedged beneath the poleward flowing Gulf Stream and the continental slope. This counterflow is likely the upper part of the equatorward-flowing Deep Western Boundary Current (DWBC). Hydrographic data suggest that the equatorward flow sampled by the shipboard 38 kHz ADCP comprises the Upper Labrador Sea Water (ULSW) layer and top of the Classical Labrador Sea Water (CLSW) layer. Continuous DWBC flow around the Cape implied by the closely-spaced velocity sections here is also corroborated by the trajectory of an Argo float...

During the Deepwater Horizon blowout, unprecedented volumes of dispersant were applied both on the surface and at depth. Application at depth was intended to disperse the oil into smaller microdroplets that would increase biodegradation and also reduce the volumes buoyantly rising to the surface, thereby reducing surface exposures, recovery efforts, and potential stranding. In forensically examining 5300 offshore water samples for the Natural Resource Damage Assessment (NRDA) effort, profiles of deep-plume oil droplets (from filtered water samples) were compared with those also containing dispersant indicators to reveal a previously hypothesized but undocumented, accelerated dissolution of the polycyclic aromatic hydrocarbons (PAH) in the plume samples...

The economic impact of disasters is well known; however, the link between financial loss and behavioral health problems is unknown. Participants included 198 adults of ages 21 to 82, living within 10 miles of the Gulf Coast during the Deepwater Horizon Oil Spill and were involved in the fishing, harvesting, seafood processing, or service/tourism industries. The functional impact of financial resource loss at 2.5 years post spill was measured using the 26-item Financial Life Events Checklist (FLEC). Individuals responded to financial distress by reducing social events and utility bills and changing food-shopping habits...

The Beibu Gulf (also named the Gulf of Tonkin), located in the northwest of the South China Sea, is representative of a bay suffering from turbulence and contamination associated with rapid industrialization and urbanization. In this study, we aim to provide the novel baseline levels of heavy metals for the research area. Concentrations of five heavy metals (i.e., Cu, Pb, Zn, Cd and Cr) were determined in surface sediments from 35 sites in the eastern Beibu Gulf. The heavy metal content varied from 6.72 to 25...

In light of increasingly high rates of diabetes, heart disease, and obesity among citizens of the Arabian Gulf, popular health discourse in the region has emphasised the emergent Arab genome as the primary etiological basis of major health conditions. However, after many years of public dissemination of genomic knowledge in the region, and widespread acceptance of this knowledge among Gulf Arab citizens, the rates of chronic illness continue to increase. This paper briefly explores the clash between indigenous Islamic knowledge systems and biomedical knowledge systems imported into the United Arab Emirates...

Since the establishment of the coastal industrial complex in Gabes city (Gulf of Gabes, SE Tunisia), hundred million tons of untreated phosphogypsum have been discharged in the open sea causing serious environmental problems. To better understand the dynamic and behavior of phosphate/phosphogypsum contaminants from raw ores to marine environment, a chemical, organic, mineralogical, and morphological characterization of phosphate rock and phosphogypsum was conducted using several sophisticated techniques. The chemical analysis showed that phosphate and phosphogypsum contain high loads of trace elements and that the transfer factors of pollutants varied from 5...

Culture of the eastern oyster (Crassostrea virginica) is rapidly expanding. Combined with their continuing role as an environmental sentinel species and ecological model, this trend necessitates improved molecular tools for breeding and selection, as well as population assessment and genetic conservation. Here, we describe the development and validation of two panels of 58 single nucleotide polymorphism markers (SNPs) for the species. Population analyses revealed three distinct populations, based on FST values and STRUCTURE, among wild oysters sampled from Delaware Bay (1), northwest Florida (2), Alabama (2), Louisiana (2), and the Texas Gulf Coast (3), consistent with previous microsatellite and mtDNA analyses...

It remains a mystery how Pama-Nyungan, the world's largest hunter-gatherer language family, came to dominate the Australian continent. Some argue that social or technological advantages allowed rapid language replacement from the Gulf Plains region during the mid-Holocene. Others have proposed expansions from refugia linked to climatic changes after the last ice age or, more controversially, during the initial colonization of Australia. Here, we combine basic vocabulary data from 306 Pama-Nyungan languages with Bayesian phylogeographic methods to explicitly model the expansion of the family across Australia and test between these origin scenarios...

Bioenergy with carbon capture and storage (BECCS) is a negative-emissions technology that may play a crucial role in climate change mitigation. BECCS relies on the capture and sequestration of carbon dioxide (CO2 ) following bioenergy production to remove and reliably sequester atmospheric CO2 Previous BECCS deployment assessments have largely overlooked the potential lack of spatial colocation of suitable storage basins and biomass availability, in the absence of long-distance biomass and CO2 transport. These conditions could constrain the near-term technical deployment potential of BECCS due to social and economic barriers that exist for biomass and CO2 transport...

Our objective of this study was to explore the bacterial microbiome in fresh or fresh-frozen adult Amblyomma maculatum (Gulf Coast ticks) using extracts enriched for microbial DNA. We collected 100 questing adult A. maculatum, surface disinfected them, and extracted DNA from individual ticks collected the same day or after storage at -80 °C. Because only extracts with microbial DNA concentrations above 2 ng/μL were considered suitable for individual analysis, we expected fewer samples to meet these requirements...

The autoimmune/autoinflammatory syndrome induced by adjuvants (ASIA) was first described in 2011. The aluminium containing adjuvants of vaccines were stated to be one of the main causes of the condition. Other disorders associated with ASIA include siliconosis, Gulf war syndrome, sick building syndrome and the macrophagic myositis syndrome. We have recently reviewed ASIA as defined by its authors. We have shown that the definition of ASIA is imprecise and includes all patients with an autoimmune disorder as well as potentially the entire population...

Autoimmune Syndrome Induced by Adjuvant (ASIA) is a definition aimed to describe the common etiological process at the root of five clinical entities sharing similar symptomatology: macrophagic myofasciitis syndrome (MMF), Gulf War Syndrome (GWS), sick building syndrome (SBS), siliconosis, and post vaccination autoimmune phenomena. ASIA illustrates the role of environmental immune stimulating agents, or adjuvants, in the instigation of complex autoimmune reactions among individuals bearing a genetic preponderance for autoimmunity...

OBJECTIVES: Intense migrations from tuberculosis endemic areas to Gulf countries create special risks to people in the region. The purpose of this study is to provide data that could justify implementing a universal, regular TB screening in UAE. DESIGN: This prospective, cross-sectional study used interferon-γ release assay (IGRA) to screen for TB among Emirati citizens between August-2016 and May-2017; expatriates were not included in this study. Participants were recruited from Emiratis attending Tawam Hospital Polyclinics for problems unrelated to TB risk assessment...

Persistent organic pollutants (POPs) are long-range transported to the Arctic via atmospheric and oceanic currents, where they biomagnify to high concentrations in the tissues of apex predators such as polar bears (Ursus maritimus). A major concern of POP exposure is their physiological effects on vital organ-tissues posing a threat to the health and survival of polar bears. Here we examined the relationship between selected POPs and baculum bone mineral density (BMD) in the East Greenland and seven Canadian subpopulations of polar bears...

Ticks are the major vectors of most disease-causing agents to humans, companion animals and wildlife. Moreover, ticks transmit a greater variety of pathogenic agents than any other blood-feeding arthropod. Ticks have been expanding their geographic ranges in recent decades largely due to climate change. Furthermore, tick populations in many areas of their past and even newly established localities have increased in abundance. These dynamic changes present new and increasing severe public health threats to humans, livestock and companion animals in areas where they were previously unknown or were considered to be of minor importance...
