John M S Pearce
Edgar Douglas Adrian was an outstandingly brilliant, Nobel prize-winning neurophysiologist. He is remembered for developing the all-or-none principle of muscle contraction, and for explaining the minutiae of motor and sensory nerve transmission. He showed that the afferent effect in a neuron depends on the pattern in time of the impulses travelling in it, thereby providing a quantitative basis of nervous behaviour. With Sir Charles Sherrington, he was awarded the Nobel Prize in 1932 for discoveries on the functions of the neurons...

Qingzhong Huang, Qiang Liu, Jinsong Xia
We have proposed and studied a novel channel add-drop filter (ADF) based on a single Fabry-Perot resonator. The resonator consists of two mode-conversion Bragg grating reflectors separated by a wide waveguide that laterally coupled to two narrow waveguides. It behaves like a traveling-wave resonator where fields are coupled to the buses in one direction. Compact and narrowband ADFs are achieved with dropping efficiencies higher than 95%, as shown by the three-dimensional finite-difference time-domain simulations...

There are many aspects-political, economic, legal, medical, cultural, religious-of the present refugee crisis in Europe. Difficulties at border crossings, settlement programs, life-saving issues, and security measures come to mind immediately, but the refugee crisis also needs to be examined from a psychological angle. This paper outlines psychoanalytic findings on voluntary and forced immigration and human responses to the Other. Change in the twenty-first century is occurring at an unprecedented pace and scale...

Immigrant travelers who visit friends and relatives (VFR travelers) experience substantially higher rates of travel-related infections than other travelers, in part due to low uptake of pretravel health advice. While barriers to accessing advice have been identified, better characterization is needed to inform targeted interventions. We sought to understand how South Asian VFR travelers perceived and responded to travel-related health risks by conducting group interviews with 32 adult travelers from an ethnoculturally diverse Canadian region...

The prevalence of methicillin-resistant Staphylococcus aureus (MRSA) in Pakistan is known to be high, but very few studies have described the molecular epidemiology of the different MRSA clones circulating in the country. Forty-four MRSA isolates were collected from two tertiary care hospitals of the Rawalpindi district of Pakistan. All strains were identified by a conventional phenotypic method and then subjected to genotyping by microarray hybridisation. Six clonal complexes (CCs) and 19 strains were identified...

Melioidosis is a frequently fatal infection caused by the Gram-negative bacillus Burkholderia pseudomallei endemic to Southeast Asia and Northern Australia. It is a rare imported pathogen in the United States and is a potential bioterror agent. We report the case of an 82-year-old previously healthy man who presented with 2 weeks of fever and epigastric pain after he returned from the Philippines. A diagnosis of nondissecting mycotic aneurysm in the descending thoracic aorta was made with the help of CT angiogram and positive blood cultures...

The purpose of this study was to provide a position specific (middle, link [male], link [female], wing) analysis of mixed gender touch on the physical physiological and perceptual demands of amateur players during match-play across a season. Distance and speed measures were obtained through the use of 10-Hz global positioning system devices, whilst telemetric heart rate devices were used determine a range of physiological measures. Players also provided a rating of perceived exertion following each match. The greatest physical demand was associated with the middle playing position by comparison to all others (Distance travelled ≥5...

Electric arc welding is a routine operation in the construction of metallic structures, but the fumes generated during the welding process can threaten the health of welders. Fumes are undesirable products of the majority of welding operations and may have various detrimental effects on health. The purpose of this study was to investigate the effect of operational parameters of the shielded metal arc welding (SMAW) process on the emission of fumes. A dust monitor was used to measure the number and mass concentration of fumes generated by SMAW...

The Foodborne Diseases Active Surveillance Network (FoodNet) conducts population-based surveillance for Campylobacter infection. For 2010 through 2015, we compared patients with Campylobacter jejuni with patients with infections caused by other Campylobacter species. Campylobacter coli patients were more often >40 years of age (OR = 1·4), Asian (OR = 2·3), or Black (OR = 1·7), and more likely to live in an urban area (OR = 1·2), report international travel (OR = 1·5), and have infection in autumn or winter (OR = 1·2)...

Background: Atovaquone/proguanil, registered as Malarone®, is a fixed-dose combination recommended for first-line treatment of uncomplicated Plasmodium falciparum malaria in non-endemic countries and its prevention in travellers. Mutations in the cytochrome bc1 complex are causally associated with atovaquone resistance. Methods: This systematic review assesses the clinical efficacy of atovaquone/proguanil treatment of uncomplicated malaria and examines the extent to which codon 268 mutation in cytochrome b influences treatment failure and recrudescence based on published information...

Dendritic cells (DCs) are specialized immune cells that scan peripheral tissues for foreign material or aberrant cells and, upon recognition of such danger signals, travel to lymph nodes to activate T cells and evoke an immune response. For this, DCs travel large distances through the body, encountering a variety of microenvironments with different mechanical properties such as tissue stiffness. While immune-related pathological conditions such as fibrosis or cancer are associated with tissue stiffening, the role of tissue stiffness in regulating key functions of DCs has not been studied yet...

This paper explores intra-regional South-South cross-border patient travel within the context of Southern Africa. South Africa, in particular, has been widely touted as one of the emerging destinations of high-end patients from the Global North alongside other destinations such as Brazil, India, Costa Rica and Thailand. Using South Africa as a case study, the paper demonstrates that South-South cross-border patient travel is far more significant than North-South patient travel both in numerical and financial terms...

Here we explore the combination of constant and oscillatory fields applied in a single device to affect the continuous separation and filtering of ions based on their mobilities. The device explored allows confining and manipulating ions utilizing a combination of radio frequency (rf), direct current (DC) fields, and traveling waves (TW) in a structures for lossless ion manipulations (SLIM) module. We have investigated theoretically and experimentally a concept for continuous filtering of ions based on their mobilities where ions are mobility separated and selected by passage through two regions, both of which incorporated combined TW and constant fields providing opposing forces on the ions...

REVIEW

Experimental evidence is accumulating that endosymbionts of phytophagous insects may transmit horizontally via plants. Intracellular symbionts known for manipulating insect reproduction and altering fitness (Rickettsia, Cardinium, Wolbachia, and bacterial parasite of the leafhopper Euscelidius variegatus) have been found to travel from infected insects into plants. Other insects, either of the same or different species can acquire the symbiont from the plant through feeding, and in some cases transfer it to their progeny...

Seasonal variation in human mobility is globally ubiquitous and affects the spatial spread of infectious diseases, but the ability to measure seasonality in human movement has been limited by data availability. Here, we use mobile phone data to quantify seasonal travel and directional asymmetries in Kenya, Namibia, and Pakistan, across a spectrum from rural nomadic populations to highly urbanized communities. We then model how the geographic spread of several acute pathogens with varying life histories could depend on country-wide connectivity fluctuations through the year...

REVIEW
Clay M Armstrong, Stephen Hollingworth
We are wired with conducting cables called axons that rapidly transmit electrical signals (e.g., "Ouch!") from, for example, the toe to the spinal cord. Because of the high internal resistance of axons (salt water rather than copper), a signal must be reinforced after traveling a short distance. Reinforcement is accomplished by ion channels, Na channels for detecting the signal and reinforcing it by driving it further positive (to near 50 mV) and K channels for then restoring it to the resting level (near -70 mV)...
