A 55year old woman in New York City presented in May 2016 with progressive weakness, ataxia, paresthesia, and areflexia, shortly after returning from the Dominican Republic. Lumbar puncture revealed cytoalbuminological dissociation. Due to her recent travel, Zika-associated Guillain Barré syndrome (GBS) was suspected and she underwent evaluation for recent flavivirus exposure. Zika virus RNA was not detected in serum, but Zika virus immunoglobulin M (IgM) was detected in both serum and cerebrospinal fluid...

Despite ongoing efforts to improve rural healthcare, the health problems facing rural communities persist. The lack of healthcare providers and infrastructure in rural areas has been linked to a number of negative consequences. Among the elderly rural population, the lack of proximal access presents greater barriers because many elderly people are further limited in their ability to travel and pay for services. In the Deep South specifically, rural residents experience limited access to care and overall poor health outcomes...

With the intensification of human activities, fresh water resources are increasingly being exposed to contamination from effluent disposal to land. Thus, there is a greater need to identify the sources and pathways of water contamination to enable the development of better mitigation strategies. To track discharges of domestic effluent into soil and groundwater, 10 synthetic double-stranded DNA (dsDNA)(3) tracers were developed in this study. Laboratory column experiment and field groundwater and soil lysimeter studies were carried out spiking DNA with oxidation-pond domestic effluent...

Traveling wave ion mobility (TWIM) mass spectrometry (MS) is a powerful method for the structural and conformational analysis of proteins and peptides, enabling the differentiation of isomeric peptides (or proteins) that have the same sequence but are modified at different residues. In this study, the TWIM-MS technique was used to separate isomeric Au(I) metallopeptide ions that were formed by Zn(II) displacement from the parent zinc fingers (ZFs). The synthetic gold finger peptides were derived from the C-terminus of the HIV nucleocapsid p7 protein (NCp7-F2) and finger 3 of the Sp1 transcription factor (Sp1-F3)...

History A previously healthy 28-year-old man developed right lower quadrant pain while traveling. The pain progressed over the course of 2-3 days, and his family took him to a local emergency department. He was found to have an elevated white blood cell count of 12.2 × 10(9)/L (reference range, [3.9-10.3] × 10(9)/L), with a predominance of neutrophils. Contrast material-enhanced computed tomography (CT) of the abdomen and pelvis was performed, and findings were abnormal. The patient elected to leave the emergency department without undergoing treatment, and he returned home via airplane...

BACKGROUND: To determine the relationship between the perforating and deep lymphatic vessels in the knee region for clinical implications. METHODS: Four lower limbs from two unembalmed human cadavers were used. Under a surgical microscope, 6% hydrogen peroxide was employed to detect lymph vessels accompanying the small saphenous vein, anterior tibial, posterior tibial and fibular blood vessels all commencing from distal ends of specimens. Each lymphatic vessel was inserted by a 30-gauge needle and injected with a barium sulphate mixture...

In this article, composites consisting of porous Ni cores coated with boehmite/nickel aluminum oxide nanoflakes were successfully prepared by a versatile method. The crystal constituents and shapes of the boehmite/nickel aluminum oxide nanoflakes were strongly influenced by reaction temperature, and their microwave absorption properties were investigated in terms of complex permittivity and permeability. The results reveal that the composites comprising porous Ni cores coated with boehmite/nickel aluminum oxide synthesized at 180 °C present superior absorption properties...

A "dirty bomb" is a type of radiological dispersal device (RDD) that has been the subject of significant safety and security concerns given the disruption that would result from a postulated terrorist attack. Assessing the risks of radioactive dose in a hypothetical scenario requires models that can accurately predict dispersion in a realistic environment. Modelling a RDD is complicated by the fact that the most important phenomena occur over vastly disparate spatial and temporal length scales. Particulate dispersion in the air is generally considered on scales of hundreds to thousands of meters, and over periods of minutes and hours...

Pure iron as a potential bioresorbable material for bioresorbable coronary scaffold has major disadvantages of slow corrosion and bioresorption. However, so far, there are neither quantitative data of long-term in vivo corrosion nor direct experimental evidence for bioresorption of pure iron and its alloys, which are fundamental and vital for developing novel Fe-based alloys overcoming the intrinsic drawbacks of pure iron. This work systemically investigated scaffold performance, long-term in vivo corrosion behavior and biocompatibility of a nitrided iron coronary scaffold and explored its bioresorption mechanism...

The Middle East respiratory syndrome coronavirus (MERS-CoV), is an emerging pathogen that continues to cause outbreaks in the Arabian peninsula and in travelers from this region, raising the concern that a global pandemic could occur. Here, we show that a DNA vaccine encoding the first 725 amino acids (S1) of MERS-CoV spike (S) protein induces antigen-specific humoral and cellular immune responses in mice. With three immunizations, high titers of neutralizing antibodies (up to 1: 10(4)) were generated without adjuvant...

INTRODUCTION: The etiological diagnosis of infectious encephalitis is often not established 48hours after onset. We aimed to review existing literature data before providing management guidelines. METHOD: We performed a literature search on PubMed using filters such as "since 01/01/2000", "human", "adults", "English or French", and "clinical trial/review/guidelines". We also used the Mesh search terms "encephalitis/therapy" and "encephalitis/diagnosis". RESULTS: With Mesh search terms "encephalitis/therapy" and "encephalitis/diagnosis", we retrieved 223 and 258 articles, respectively...

Oral and facial injuries are very common in sport, and can be very expensive to treat. Many of these injuries are preventable with proper pre-competition assessment and suitable well-designed protection. Prompt sideline identification and management of orofacial injuries and appropriate follow-up are crucial to successful outcomes. There have been significant recent advances in both trauma management and mouth guard design and fabrication techniques. Athletes have a unique set of challenges-including collisions, finances, travel and training, dehydration, sport beverages, and high carbohydrate diets-that may compromise their oral health...

BACKGROUND: With respect to health care planning, it is commonly assumed that patients consult the nearest physician. In reality, however, patients frequently accept great-er efforts/expenses than necessary to see a physician. The objective of the present study was to determine under which circumstances patients were willing to accept additional efforts/expenses, and which role sociodemographic and clinical characteristics play in this regard. METHODS: Data collection was carried out in the context of a multicenter cross-sectional study among office-based and hospital-affiliated (University Medical Center Hamburg-Eppendorf) dermatologists...

We study cell navigation in spatiotemporally complex environments by developing a microfluidic racetrack device that creates a traveling wave with multiple peaks and a tunable wave speed. We find that while the population-averaged chemotaxis drift speed increases with wave speed for low wave speed, it decreases sharply for high wave speed. This reversed dependence of population-averaged chemotaxis drift speed on wave speed is caused by a "barrier-crossing" phenomenon, where a cell hops backwards from one peak attractant location to the peak behind by crossing an unfavorable (barrier) region with low attractant concentrations...

We propose a new model-independent measurement strategy for the propagation speed of gravitational waves (GWs) based on strongly lensed GWs and their electromagnetic (EM) counterparts. This can be done in two ways: by comparing arrival times of GWs and their EM counterparts and by comparing the time delays between images seen in GWs and their EM counterparts. The lensed GW-EM event is perhaps the best way to identify an EM counterpart. Conceptually, this method does not rely on any specific theory of massive gravitons or modified gravity...

Vascular Ehlers Danlos syndrome (vEDS) is an uncommon genetic disorders characterized by arterial aneurysm, dissection and rupture, bowel rupture, and rupture of the gravid uterus. The frequency is estimated as 1/50,000-1/200,000 and results from pathogenic variants in COL3A1, which encodes the chains of type III procollagen, a major protein in vessel walls and hollow organs. Initial diagnosis depends on the recognitions of clinical features, including family history. Management is complex and requires multiple specialists who can respond to and manage the major complications...

Mammals constantly face stressful situations, be it extended periods of starvation, sleep deprivation from fear of predation, changing environmental conditions, or loss of habitat. Today, mammals are increasingly exposed to xenobiotics such as pesticides, pollutants, and antibiotics. Crowding conditions such as those created for the purposes of meat production from animals or those imposed upon humans living in urban environments or during world travel create new levels of physiologic stress. As such, human progress has led to an unprecedented exposure of both animals and humans to accidental pathogens (i...
