This study investigated metal contamination from historical mining in lakes in the Tasmanian Wilderness World Heritage Area (TWWHA) and surrounding region. The largest increase in sedimentation and metal contamination occurred ca. 1930 when open-cut mining commenced and new mining technology was introduced into the region. The geochemical signal of lake sediments changed from reflecting the underlying geology and lithology to that reflecting mining activities. The HYSPLIT air particle trajectory model explains metal distribution in the lakes, with those in the northwest region closest to the mines having the highest metal contamination...

The border between self-harm and suicidal behaviors is not always clear. Self-mutilation is a common finding in mood and personality disorders, and cutting of the extremities is more common than cutting of the neck. The case put forth regards a young adult male with a past history of depression and drug abuse who presented to the emergency department with superficial lacerations on his left arm and bilaterally on his neck with a large abscess in his right forearm. The patient reported the cuts on his arm to be from testing the sharpness of a kitchen knife and the cuts on his neck to be the result of sexual activity between him and his girlfriend...

Novel synthetic opioids include various analogs of fentanyl and emerging non-fentanyl compounds with different chemical structures, such as AH-7921, MT-45 and U-47700. In recent years, these drugs have rapidly emerged on the drug market, and their abuse has been increasing worldwide. The motivations for use of these new compounds include their legal status, ready availability, low cost, users' curiosity or preference for their particular pharmacological properties and the intention to avoid detection. Furthermore, more common drugs like heroin are now increasingly being replaced or cut with fentanyl or new designer opioids; thus, many drug users are unintentionally or unknowingly using synthetic fentanyl analogs...

This study presents an innovative approach to hand-coding parties' policy preferences in the relatively new, cross-sectoral field of climate change mitigation policy. It applies this approach to party manifestos in six countries, comparing the preferences of parties in Denmark, France, Germany, Ireland, Italy and the United Kingdom over the past two decades. It probes the data for evidence of validity through content validation and convergent/discriminant validation and engages with the debate on position-taking in environmental policy by developing a positional measure that incorporates 'pro' and 'anti' climate policy preferences...

Over the past two decades, the nickel-titanium (NiTi) rotary instruments have highly improved the quality of the cleaning and shaping of the root canals. The superelasticity and shape memory of these instruments reduce the possibility of the canal transportation along with saving the time for both the patients and the clinicians. Several commercial types of these instruments, produced by different manufacturers, have currently become available by modifying the characteristics of the wonder NiTi alloy and also the cross-sectional shapes, cutting edges, tapering and numbers and distances of the flutes of the instruments...

In every society where non-therapeutic female circumcision (FC) occurs, so too does non-therapeutic male circumcision (MC). In the past few decades, the norm in Euro-American societies has been to distinguish between the practices: FC is banned, while MC is condoned or encouraged. We explored Somalis' post-migration perceptions of FC and MC, while considering that they once lived in a society where both practices were widely accepted and now live in a society where there is a legal ban on FC alongside acceptance of MC...

BACKGROUND: Changes in our lifestyle over the past few decades have led to a significant increase in the worldwide prevalence of both overweight (defined as a body mass index [BMI]≥25 kg/m) and obesity (BMI≥30 kg/m), thus leading to numerous harmful consequences for an individual's health. Several meta-analyses support the link between obesity and different gastrointestinal cancers, but substantial heterogeneity exists between studies. We will synthesize published systematic reviews to evaluate the association between body mass index (BMI) and the incidence and mortality of different gastrointestinal cancers...

The phase noise of surface acoustic wave resonators is explored by a passive measurement system based on the carrier suppression technique. The measurements are focused on 2.44 GHz quartz crystal resonators. These resonators are characterized in term of motional parameters. The power dissipated through the resonators is around 500 μW. The second order frequency-temperature coefficient of the resonators has been measured to be around -0.038 ppm/°C2 that corresponds to a classical ST-cut. The resonator conditioning is presented...

Bloomy rind cheeses, including Camembert and related varieties, can be produced using alternative processes that vary based on milk preacidification, cutting, curd handling, and ripening parameters. Modification of these parameters creates distinct cheeses such as lactic curd, stabilized curd, and hybrids of the two. The objective of this study was to determine the influence of 5 Camembert-type cheese recipes on the composition and characteristics during ripening. Five varieties of Camembert-type cheese were produced: (1) lactic curd, (2) sweet curd, (3) washed curd, (4) solubilized curd, and (5) stabilized curd...

Protein-based materials are finding new uses and applications after millennia of impacting the daily life of humans. Some of the earliest uses of protein-based materials are still evident in silk and wool textiles and leather goods. Today, even as silks, wools and leathers are still be used in traditional ways, these proteins are now seen as promising materials for biomaterials, vehicles of drug delivery and components of high-tech fabrics. With the advent of biosynthetic methods and streamlined means of protein purification, protein-based materials-recombinant and otherwise-are being used in a host of applications at the cutting edge of medicine, electronics, materials science and even fashion...

The leaves of the Mitragynine speciosia tree (also known as Kratom) have long been chewed, smoked, or brewed into a tea by people in Southeastern Asian countries, such as Malaysia and Thailand. Just this past year, the plant Kratom gained popularity in the United States as a "legal opioid" and scheduling it as a drug of abuse is currently pending. The primary alkaloid found in Kratom is a μ-opioid receptor agonist, mitragynine, whose structure contains a promising scaffold for immunopharmacological use...
