The classic presentation of acute gastrointestinal (GI) parasitic infection including fever, diarrhea, nausea, and/or abdominal pain is not always a reliable measure. In these cases, parasitic infections require sensitive stool testing to be identified and treated effectively. The standard practice for stool analysis typically requires 3 separate stool specimens to be collected on 3 separate days to overcome the possibility of misdiagnosis due to intermittent shedding. Nonetheless, this practice is not often utilized due to very short periods of sample viability, which often leads to patient misdiagnosis...

Mental time travel (MTT) allows navigation into the past, the future, and the minds of others, and it subserves future-oriented decision-making. Impaired MTT has been associated with a tendency to over-rely on the present, which is a characteristic of addictive behaviors. We here discuss the possible relationship between impaired autographical memory, future-oriented MTT, shortened time horizons, suboptimal social cognition, and poor decision-making in individuals with drug and gambling use disorders. We elaborate on how impaired MTT could compromise the process of change in addiction recovery and the effectiveness of psychotherapy...

The intracellular compartments for proteolytic antigen processing in tumor cells produce peptides that are presented by MHC molecules to T cells. But first, the ubiquitin ligase system tags defective, misfolded, aged, and unstable proteins for degradation through the proteasome. Ubiqitinated proteins are unfolded and fed into the barrel-shaped core of the proteasome where a collection of multiple different proteases cleave proteins into oligopeptides. After exiting the proteasome, these oligopeptides are either completely degraded into amino acids or trimmed at the N- and C-termini so that they bind to transporter associated with antigen processing (TAP)...

BACKGROUND: There are limited data about the persistence and infectivity of Zika virus in semen of symptomatic travelers returning from endemic areas and even less data in asymptomatic cases. OBJECTIVE: We investigated the persistence and infectivity of ZIKA virus in semen in five patients with Zika virus infection returning to Spain from endemic areas. STUDY DESIGN: We evaluated the epidemiological, clinical and virological characteristic of the five patients...

Thermal manipulation during embryogenesis was previously reported to decrease the occurrence of ascites and to potentially improve cold tolerance of broilers. The objective of our study was to explore the effects of the interaction of cold incubation temperatures and cool ambient temperatures until 21 d of age on performance and body temperature. Ross 308 eggs were incubated either under control conditions I0 (37.6°C) or with cyclic cold stimulations I1 (6 h/d at 36.6°C from d 10 to 18 of incubation) or with 2 cold stimulations I2 (30 min at 15°C) at d 18 and 19 of incubation...

The remotely supervised tDCS (RS-tDCS) protocol enables participation from home through guided and monitored self-administration of tDCS treatment while maintaining clinical standards. The current consensus regarding the efficacy of tDCS is that multiple treatment sessions are needed to observe targeted behavioral reductions in symptom burden. However, the requirement for patients to travel to clinic daily for stimulation sessions presents a major obstacle for potential participants, due to work or family obligations or limited ability to travel...

Sandhill Cranes (Antigone canadensis) of the midcontinent population (MCP) and Rocky Mountain population (RMP) are migratory game birds with stable populations that travel between Canada and the southern USA and Mexico. In the winters of 2012-14, we performed gross and histologic examinations of 43 hunter-harvested Sandhill Cranes in Texas (MCP) and New Mexico (RMP) to assess the impact of disease on populations. Lesions were significantly more common in the MCP relative to the RMP, likely reflecting differential environmental exposure to pathogens and parasites...

BACKGROUND AND OBJECTIVES: International travel assists spread of infectious pathogens. Australians regularly travel to South-eastern Asia and the isles of the South Pacific, where they may become infected with infectious agents, such as dengue (DENV), chikungunya (CHIKV) and Zika (ZIKV) viruses that pose a potential risk to transfusion safety. In Australia, donors are temporarily restricted from donating for fresh component manufacture following travel to many countries, including those in this study...

Impoverished men have lower rates of facility-based HIV counseling and testing and higher unknown HIV-positive status than women. Economic theory suggests that individuals will obtain an HIV test if anticipated benefits are greater than anticipated costs. Yet, few studies have investigated the range of financial preferences of HIV self-testing (HIVST) among poor men who decline testing or do not test regularly. Twenty-three interviews were conducted to qualitatively assess perceived costs saved and costs incurred from use of HIVST kits in infrequently- or never-tested Tanzanian men...

The law of momentum conservation rules out many desired processes in optical microresonators. We report broadband momentum transformations of light in asymmetric whispering gallery microresonators. Assisted by chaotic motions, broadband light can travel between optical modes with different angular momenta within a few picoseconds. Efficient coupling from visible to near-infrared bands is demonstrated between a nanowaveguide and whispering gallery modes with quality factors exceeding 10 million. The broadband momentum transformation enhances the device conversion efficiency of the third-harmonic generation by greater than three orders of magnitude over the conventional evanescent-wave coupling...

The rapid clearance of malaria parasite DNA from circulation has widely been accepted as a fact without being systemically investigated. We assessed the persistence of parasite DNA in travelers treated for Plasmodium falciparum malaria in a malaria-free area. Venous blood was collected at the time of admission and prospectively up to one year. DNA and RNA were extracted and analyzed using species-specific and gametocyte-specific real-time PCR as well as merozoite surface protein 2 (msp2)-PCR. In 31 successfully treated individuals, asexual parasites were seen by microscopy until two days after treatment, whereas parasite DNA was detected by msp2- and species-specific PCR up to days 31 and 42, respectively...

We describe a case of imported cutaneous gnathostomiasis in a Thai patient living in France. Gnathostomiasis is a zoonosis of food origin. The disease is endemic in Southeast Asia and Latin America. However, over the past 30 years, an increasing number of imported cases has been described in Europe and America. The disease is rare in Western Europe and the majority of cases described had a cutaneous clinical presentation. The disease may sometimes be confused with allergy, leading to a delay in diagnosis. Visceral symptoms are rare but may follow severe attacks...

The aim of this study was to identify the type of research (Internet, phone lines, friends, family, media or medical journal) undertaken by university students with sexual health concerns, and the effect this research had on their healthcare-seeking behaviour. The Internet was the most common (46%) first point of call for health information, closely followed by doctors (40%). Of those who undertook extra research, the majority subsequently went to a doctor. Health practitioners need to be aware of this tendency for independent research...

Introduction There is a growing interest in the use of e-learning in medical education. However until recently there has been little interest in the potential environmental benefits of e-learning. This paper models various environmental outcomes that might emerge from the use of an e-learning resource (BMJ Learning) in CPD. Methods We modeled the use of e-learning as a component of CPD and evaluated the potential impact of this use on the learner's carbon footprint. We looked at a number of models - all from the perspective of a General Practitioner (GP)...

Background: Excess skin cancer mortality and incidence have been reported among both land-based and offshore petroleum workers. The association between skin cancer and ultraviolet radiation (UVR) exposure has not been examined in these workers, although they have long off-duty periods and high average income that may allow travelling to sunny destinations. In addition, they have access to solariums free of charge on many accommodation platforms. Aims: To prospectively examine risk of incident cutaneous melanoma (CM) and non-melanoma skin cancer (NMSC), according to sun-tanning habits with adjustment for aromatic hydrocarbon exposure...

We report Mycobacterium lepromatosis infection in a US-born person with an extensive international travel history. Clinical symptoms, histopathology, and management are similar to those of infections caused by M. leprae. Clinicians should consider this pathogen in the diagnosis of patients with symptoms of leprosy who have traveled to endemic areas.

Scottish publisher and naturalist Robert Chambers pursued an amateur interest in geology through much of his life. His early measurements of raised beaches in Scotland earned him membership in the Geological Society of London in 1844, a recognition much appreciated by the anonymous author of the 'scandalous' Vestiges published the same year. Although familiar with emerging ice age theories, Chambers remained with most British geologists a sceptic through the 1840s, even after a trip to the glaciers of the Alps in 1848, which nevertheless prepared him for the turning point, which came in 1849 during an extensive field trip in Norway and Sweden...

A quarter-wave layer (QWL) of high refractive index, which is deposited on a transparent prism of low refractive index, can be designed to split an incident p-polarized light beam at the Brewster angle (BA) of the air-substrate interface into p-polarized reflected and transmitted beams of equal intensity (50% each) that travel in orthogonal directions. For reflection of p-polarized light at the BA, the supported QWL functions as a free-standing (unsupported) pellicle. An exemplary design is presented that uses SixGe1-x QWL deposited on an IRTRAN1 prism for applications (such as Michelson and Mach-Zehnder interferometry) with a variable compositional fraction x in the 2-6 μm mid-IR spectral range...
