BACKGROUND AND OBJECTIVES: Primary care physicians (PCPs) can play a critical role in addressing unintended pregnancy through high-quality options counseling and referrals. METHODS: We surveyed a nationally representative sample of 3,000 PCPs in general, family, and internal medicine on practices and opinions related to options counseling for unintended pregnancy. We assessed predictors of physician practices using multivariable logistic regression weighted for sampling design and differential non-response...

Research on the perception of facial emotional expressions (FEEs) often uses static images that do not capture the dynamic character of social coordination in natural settings. Recent behavioral and neuroimaging studies suggest that dynamic FEEs (videos or morphs) enhance emotion perception. To identify mechanisms associated with the perception of FEEs with natural dynamics, the present EEG (Electroencephalography)study compared (i) ecologically valid stimuli of angry and happy FEEs with natural dynamics to (ii) FEEs with unnatural dynamics, and to (iii) static FEEs...

The developing region of SAARC (South Asian Association for Regional Cooperation) is home to a large number of people living below the poverty line. In future, providing affordable, universally accessible, reliable, low to zero carbon electricity in this region will be the main aim. A cost optimal 100% renewable energy system is simulated for SAARC for the year 2030 on an hourly resolved basis. The region was divided into 16 sub-regions and three different scenarios were set up based on the level of high voltage direct current (HVDC) grid connections...

INTRODUCTION AND OBJECTIVES: Although the Iberian Peninsula is a key area for understanding the Middle to Upper Paleolithic transition and the demise of the Neandertals, valuable evidence for these debates remains scarce and problematic in its interior regions. Sparse data supporting a late Neandertal persistence in the Iberian interior have been recently refuted and hence new evidence is needed to build new models on the timing and causes of Neandertal disappearance in inland Iberia and the whole peninsula...

Top sports performances cannot be achieved without a high level of postural control. Balance wristbands purport to improve the mental and physical balance of the wearer. It is still unclear, however, whether these wristbands can indeed enhance postural control. Our purpose was to ascertain by means of computerized dynamic posturography whether balance wristbands can improve postural stability.In this randomized controlled single-blind clinical study, posturography was used to assess postural control in 179 healthy subjects with or without a balance wristband...

RATIONALE: Congenital tuberculosis (TB) is described as a rare, but severe disease. In contrast to the cases with severe symptoms reported so far, we describe a child with asymptomatic congenital TB. PATIENT CONCERNS: An 8-week-old girl was investigated because of newly diagnosed TB in her mother, which complained about cough since 21 weeks gestation. Lung biopsy tissue specimens of the mother revealed necrotizing granuloma with a single acid-fast bacillus (AFB) and Mycobacterium tuberculosis (MTB) was detected by polymerase chain reaction...

Aberrations in intracellular calcium (Ca(2+)) have been well established within amyotrophic lateral sclerosis (ALS), a severe motor neuron disease. Intracellular Ca(2+) concentration is controlled in part through the endoplasmic reticulum (ER) mitochondria Ca(2+) cycle (ERMCC). The ER supplies Ca(2+) to the mitochondria at close contacts between the two organelles, i.e. the mitochondria-associated ER membranes (MAMs). The Sigma 1 receptor (Sig1R) is enriched at MAMs, where it acts as an inter-organelle signalling modulator...

Spectroscopic infrared chemical imaging is ideally suited for label-free and spatially resolved characterization of molecular species, but often suffers from low infrared absorption cross sections. Here, we overcome this limitation by utilizing confined electromagnetic near-fields of resonantly excited plasmonic nanoantennas, which enhance the molecular absorption by orders of magnitude. In the experiments, we evaporate microstructured chemical patterns of C60 and pentacene with nanometer thickness on top of homogeneous arrays of tailored nanoantennas...

This report describes a method for Pd-catalyzed decarbonylative cross-coupling that enables the conversion of carboxylic acid derivatives to biaryls, aryl amines, aryl ethers, aryl sulfides, aryl boronate esters, and trifluoromethylated arenes. The success of this transformation leverages the Pd(0)/Brettphos-catalyzed decarbonylative chlorination of aroyl chlorides, which can then participate in diverse cross-coupling reactions in situ using the same Pd catalyst.

Protein phosphorylation is by far the most abundant and most studied post-translational modification (PTM). For a long time, phosphate monoesters of serine (pSer), threonine (pThr), and tyrosine (pTyr) have been considered as the only relevant forms of phosphorylation in organisms. Recently, several research groups have dedicated their efforts to the investigation of other, less characterized phosphoamino acids as naturally occurring PTMs. Such apparent peculiar phosphorylations include the phosphoramidates of histidine (pHis), arginine (pArg), and lysine (pLys), the phosphorothioate of cysteine (pCys), and the anhydrides of pyrophosphorylated serine (ppSer) and threonine (ppThr)...

FGF2 is secreted from cells by an unconventional secretory pathway. This process is mediated by direct translocation across the plasma membrane. Here, we define the minimal molecular machinery required for FGF2 membrane translocation in a fully reconstituted inside-out vesicle system. FGF2 membrane translocation is thermodynamically driven by PI(4,5)P2-induced membrane insertion of FGF2 oligomers. The latter serve as dynamic translocation intermediates of FGF2 with a subunit number in the range of 8-12 FGF2 molecules...

Mass administration of azithromycin (MDA) is integral to trachoma control. Recent studies suggest that MDA may increase drug-resistant pathogens, yet findings from prior studies suggest little long-term impact on resistance. This disparity may be linked to differences in pre-MDA community-level resistance patterns. We describe carriage prevalence and antibiotic resistance patterns for Streptococcus pneumoniae (Spn) (nasopharyngeal swab collection), Staphylococcus aureus (SA) (nasopharyngeal swabs), and Escherichia coli (EC) (rectal swabs) in 1,047 children ages 1-59 months in a district with MDA cessation 4 years ago...

Every year Christian pilgrims from around the world visit the holy sites located around the Sea of Galilee. Some become ill during their stay with infectious diseases that were acquired in their country of origin, and are hospitalized at Poriya Medical Center. They pose a diagnostic challenge due to language barriers, the rarity of these infections in Israel, and the fact that diagnostic tests are not readily available. All patient records from 2015 of Holy Land tourists hospitalized at Poriya Medical Center were screened for the diagnosis of imported zoonotic diseases that are not commonly diagnosed in Israel...

Artemisinin-based combination therapies are recommended as first-line agents for treating uncomplicated Plasmodium falciparum malaria. Ferroquine, a 4-aminoquinolone, is a novel long-acting combination partner for fast-acting drugs like artesunate (AS). We did a small phase 2a, multicenter, open-label, safety-focused dose-ranging randomized study of ferroquine at three African hospitals: two Gabonese and one Kenyan. We recruited adult men with symptomatic uncomplicated P. falciparum monoinfection. Four escalating doses of ferroquine (100, 200, 400, and 600 mg) were assessed in sequence, versus an amodiaquine comparator...

The potential health benefits of combined agricultural, nutrition, water, sanitation, and hygiene (WASH) interventions are poorly understood. We aimed to determine whether complementary school garden, nutrition, and WASH interventions reduce intestinal parasites and improve school children's nutritional status in two regions of Burkina Faso. A cluster-randomized controlled trial was conducted in the Plateau Central and Center-Ouest regions of Burkina Faso. A total of 360 randomly selected children, aged 8-15 years, had complete baseline and end-line survey data...

Etiology of acute undifferentiated febrile syndrome (AUFS) is often unknown, leading to inaccurate diagnosis and treatment. Villeta town has been identified as an endemic area for spotted fever group (SFG) rickettsioses but little is known about possible amplifier hosts and other Rickettsia species different from Rickettsia rickettsii. Besides, few studies have approached other AUFS etiologies in the region. We investigated the role of dengue, leptospirosis, rickettsioses, human anaplasmosis, and Q fever as possible causes of AUFS in patients from Villeta...

Asklepios was the main healing deity of the Classical Antiquity. After his gradual establishing, his cult expanded throughout the Greek world especially in the 5th century BC, when Asklepios reached also Athens. Around 420 BC, two sanctuaries of his (sc. Asklepieia) were founded there. Such sanctuaries were places of both the worship and therapy. The first one was located in the port of Pireus, the second one on the south slope of the Acropolis. The latter functioned as a centre of the healing cult almost until the end of the 5th century AD...

Efficient immobilization of enzymes on support surfaces requires an exact match between the surface chemistry and the specific enzyme. A successful match would normally be identified through time consuming screening of conventional resins in multiple experiments testing individual immobilization strategies. In this study we present a versatile strategy that largely expands the number of possible surface functionalities for enzyme immobilization in a single, generic platform. The combination of many individual surface chemistries and thus immobilization methods in one modular system permits faster and more efficient screening, which we believe will result in a higher chance of discovery of optimal surface/enzyme interactions...
