Chagas disease caused by the parasite, Trypanosoma cruzi is an important cause of morbidity and mortality in endemic areas of Latin America and among infected individuals who have migrated to non-endemic areas of North America and Europe. There are many diagnostic tests that are employed in the serological diagnosis of this infection.

YANG, C., S. Crain, R.C. Berwick, N. Chomsky and J.J. Bolhuis. The growth of language. NEUROSCI BIOBEHAV REV VOL (ISSUE) XXX-XXX, 2016. Human infants develop language remarkably rapidly and without overt instruction. We argue that the distinctive ontogenesis of child language arises from the interplay of three factors: domain-specific principles of language (Universal Grammar), external experience, and properties of non-linguistic domains of cognition including general learning mechanisms and principles of efficient computation...

Bioregenerative life-support systems (BLSS) address interactions between organisms and their environment as an integrated system through the study of factors that regulate the pools and fluxes of materials and energy through ecological systems. As a simple model, using BLSS is very important in the investigation of element cycling and energy flux for sustainable development on Earth. A 105-day experiment with a high degree of closure was carried out in this system from February to May, 2014, with three volunteers...

Tardigrades are microscopic organisms renowned for their ability to survive extreme environmental conditions. Tardigrade extreme-tolerance research has centered on the ability to withstand desiccation, low and high temperatures, and high hydrostatic pressure and radiation levels. Tardigrade tolerance to hypergravity, however, has yet to be described. We used the eutardigrade species Hypsibius dujardini to investigate short-term tolerance to g-equivalent accelerations (i.e., mimicking g-forces). Data obtained from specimens centrifuged between 3421g and 16,060g for 1 min inclusively reveal tolerance in an acceleration-dependent relation, with lower survivorship and egg production at higher accelerations...

The melanocortin system consists of five receptor subtypes, endogenous agonists, and naturally occurring antagonists. These receptors and ligands have been implicated in numerous biological pathways including processes linked to obesity and food intake. Herein, a truncation structure-activity relationship study of chimeric agouti-related protein (AGRP)/[Nle4, DPhe7]α-Melanocyte Stimulating Hormone (NDP-MSH) ligands is reported. The tetrapeptide His-DPhe-Arg-Trp or tripeptide DPhe-Arg-Trp replaced the Arg-Phe-Phe sequence in the AGRP active loop derivative c[Pro-Arg-Phe-Phe-Xxx-Ala-Phe-DPro], where Xxx was the native Asn of AGRP or a diaminopropionic (Dap) acid residue previously shown to increase antagonist potency at the mMC4R...

BACKGROUND: Morbidly obese patients with excessive concomitant disease carry a significantly increased perioperative risk. Although they may benefit most from a bariatric intervention, they are often denied surgery. Laparoscopic sleeve gastrectomy (LSG), as it is less complication-prone than other bariatric procedures, suits the needs of those patients. OBJECTIVE: To review the short-term outcome of LSG for high-risk patients SETTING: University hospital, Switzerland...

There is not a consensus as to whether neuropsychological profiling can distinguish depressive subtypes. We aimed to systematically review and critically analyse the literature on cognitive function in patients with melancholic and atypical depression. We searched in databases PubMed, SCOPUS, Web of Knowledge and PsycInfo for papers comparing the neuropsychological performance of melancholic patients (MEL) to non-melancholic depressive patients (NMEL), including atypical depressives, and healthy controls (HC)...

Adrian L Melott
Major discrepancies have been noted for some time between fossil ages and molecular divergence dates for a variety of taxa. Recently, systematic trends within avian clades have been uncovered. The trends show that the disparity is much larger for mitochondrial DNA than for nuclear DNA, also that it is larger for crown fossil dates than stem fossil dates. It has been argued that this pattern is largely inconsistent with incompleteness of the fossil record as the principal driver of the disparity. A case is presented that, given the expected mutations from a fluctuating background of astrophysical radiation from such sources as supernovae, the rate of molecular clocks is variable and should increase back to a few million years, before returning to the long-term average rate...

Most immune cell communication takes place by intercellular transfer of cytokines or the contact-dependent interaction of surface receptors in immunological synapses. In this issue of the European Journal of Immunology, Gardell and Parker (Eur. J. Immunol. 2016, X, XXX-XXX) point to a new, hybrid mechanism for Th1-cell delivery of help to B cells, based on contact-dependent CD40L transfer. The transfer process and its specificity are both cell contact dependent and antigen dependent. CD40 expression is also required on the B-cell surface to capture the CD40L presented by the Th1 cell...

Metal-bound isocyanides demonstrate a very rich chemistry towards 1,3-dipoles of the allyl anion type such as nitrones. Depending on the metal centre, dipole nature and substituent in isocyanides, cycloadducts, imine + isocyanates or metallacycles may be formed. In this work, the reasons for such diversity, intimate details of the reaction mechanism and main factors determining the chemoselectivity in the reaction between Au(iii)-bound isocyanides ([AuCl3(C[triple bond, length as m-dash]NR)]) and cyclic nitrones (-)O-N[combining low line](+)[double bond, length as m-dash]C(H)XXX[combining low line] (XXX = CH2CH2CMe2, CH2CH2CH2, OCH2CMe2, CH2OCMe2 and CH2CH2O) are analysed in detail by theoretical (DFT) methods...

We report our findings in a 3-year-old girl who was suspected of having triple X syndrome because she was taller than +4.35 standard deviations for her age. She also had high myopia. Optical coherence tomography (OCT) showed that her retinas were thin, the lenses were subluxated, and the axial length was elongated. Our findings indicate that for a female child with tall stature, there should be thorough evaluations for endocrinological disorders, overgrowth syndromes, connective tissue disorders, and genetic disorders...

In 1976, the Viking landers carried out the most comprehensive search for organics and microbial life in the martian regolith. Their results indicate that Mars' surface is lifeless and, surprisingly, depleted in organics at part-per-billion levels. Several biology experiments on the Viking landers gave controversial results that have since been explained by the presence of oxidizing agents on the surface of Mars. These oxidants may degrade abiotic or biological organics, resulting in their nondetection in the regolith...

To conduct crewed simulation experiments of bioregenerative life support systems on the ground is a critical step for human life support in deep-space exploration. An artificial closed ecosystem named Lunar Palace 1 was built through integrating efficient higher plant cultivation, animal protein production, urine nitrogen recycling, and bioconversion of solid waste. Subsequently, a 105-day, multicrew, closed integrative bioregenerative life support systems experiment in Lunar Palace 1 was carried out from February through May 2014...

In the last few years, water ice and salts capable of melting this ice and producing liquid saline water (brine) have been detected on Mars. Moreover, indirect evidence for brine has been found in multiple areas of the planet. Here, we simulate full diurnal cycles of temperature and atmospheric water vapor content at the Phoenix landing site for the first time and show experimentally that, in spite of the low Mars-like chamber temperature, brine forms minutes after the ground temperature exceeds the eutectic temperature of salts in contact with water ice...

Over the past five years, "ambulance-chasing" attorneys have aggressively advertised for patients who have bled on a new oral anticoagulant (NOAC) or their family members. It is an infrequent day when American consumers do not see a TV advertisement saying something like: "Have you or a loved-one had a serious bleeding event while taking [fill in the NOAC]? If so, you may be entitled to monetary compensation. Call XXX, attorneys at law, and we will get you the money you deserve."

Nitrogen is a major nutrient for all life on Earth and could plausibly play a similar role in extraterrestrial biospheres. The major reservoir of nitrogen at Earth's surface is atmospheric N2, but recent studies have proposed that the size of this reservoir may have fluctuated significantly over the course of Earth's history with particularly low levels in the Neoarchean-presumably as a result of biological activity. We used a biogeochemical box model to test which conditions are necessary to cause large swings in atmospheric N2 pressure...
