Crystal structure and Hirshfeld surface analysis of a halogen bond between 2-(allyl-thio)-pyridine and 1,2,4,5-tetra-fluoro-3,6-di-iodo-benzene.

The crystal structure of the title 2:1 mol-ecular complex between 2-(allyl-thio)-pyridine and 1,2,4,5-tetra-fluoro-3,6-di-iodo-benzene, CFI·2CHNS, at 100 K has been determined in the monoclinic space group 2/. The most noteworthy characteristic of the complex is the halogen bond between iodine and the pyridine ring with a short N⋯I contact [2.8628 (12) Å].

Regulation of CD163 Receptor in Patients with Abdominal Aortic Aneurysm and Associations with Antioxidant Enzymes HO-1 and NQO1.

Red blood cells are found within the abdominal aortic aneurysm (AAA), in the intraluminal thrombus (ILT), and in neovessels. Hemolysis promotes aortic degeneration, e.g.

Postglacial adaptations enabled colonization and quasi-clonal dispersal of ammonia-oxidizing archaea in modern European large lakes.

Ammonia-oxidizing archaea (AOA) play a key role in the aquatic nitrogen cycle. Their genetic diversity is viewed as the outcome of evolutionary processes that shaped ancestral transition from terrestrial to marine habitats. However, current genome-wide insights into AOA evolution rarely consider brackish and freshwater representatives or provide their divergence timeline in lacustrine systems.

Linking catchment structural units (CSUs) with water quality: Implications for ambient monitoring network design and data interpretation.

Climate induced changes in runoff regimes and ongoing anthropogenic modification of land use and land cover (LULC) are shifting ambient water quality signals worldwide. Modulation of these signals by the physical catchment structure over different scales adds complexity to interpreting and analyzing measured data. Further bias may be introduced where monitoring networks are not representative of the structure of catchments in a given region.

Quantification of archaea-driven freshwater nitrification from single cell to ecosystem levels.

Deep oligotrophic lakes sustain large populations of the class Nitrososphaeria (Thaumarchaeota) in their hypolimnion. They are thought to be the key ammonia oxidizers in this habitat, but their impact on N-cycling in lakes has rarely been quantified. We followed this archaeal population in one of Europe's largest lakes, Lake Constance, for two consecutive years using metagenomics and metatranscriptomics combined with stable isotope-based activity measurements.

A 12-year follow-up of intestinal schistosomiasis in pre-school-aged children in Assoni Village, Eastern Senegal.

Background: To monitor the prevalence of schistosomiasis in school-aged children (SAC), the National Bilharzia Control Program (PNLB) was set up by the Senegalese authorities; however, geographically isolated Bedik ethnic groups that did not benefit from this program were found to be heavily infected with Schistosoma mansoni. This observation led us to implement a new schistosomiasis control program in 2008 under the aegis of the non-governmental organization "Le Kaïcedrat" and in partnership with the PNLB/WHO to monitor the prevalence of schistosomiasis in this area. In the village of Assoni, where 100% of SAC were infected, analysis of the stools of pre-school-aged children (PSAC) showed that they were massively infected, so we decided to focus our program on them.

A single Thaumarchaeon drives nitrification in deep oligotrophic Lake Constance.

Ammonia released during organic matter mineralization is converted during nitrification to nitrate. We followed spatiotemporal dynamics of the nitrifying microbial community in deep oligotrophic Lake Constance. Depth-dependent decrease of total ammonium (0.

Tritonibacter horizontis gen. nov., sp. nov., a member of the Rhodobacteraceae, isolated from the Deepwater Horizon oil spill.

A heterotrophic, Gram-stain-negative, aerobic, sodium-requiring and motile bacterium was isolated from oil-contaminated surface water of the Gulf of Mexico during the Deepwater Horizon oil spill. Strain O3.65 showed highest 16S rRNA gene sequence similarity to Phaeobacter gallaeciensis BS107 and Phaeobacter inhibens T5, both with 98.

Draft genome sequence of the marine strain O3.65, cultivated from oil-polluted seawater of the Deepwater Horizon oil spill.

The marine alphaproteobacterium strain O3.65 was isolated from an enrichment culture of surface seawater contaminated with weathered oil (slicks) from the Deepwater Horizon (DWH) oil spill and belongs to the ubiquitous, diverse and ecological relevant group within the . Here, we present a preliminary set of physiological features of strain O3.

Schistosomiasis Sustained Control Program in Ethnic Groups Around Ninefescha (Eastern Senegal).

Schistosomiasis is the second most significant parasitic disease in children in several African countries. For this purpose, the "Programme National de Lutte contre les Bilharzioses" (PNLB) was developed in partnership with the World Health Organization (WHO) to control this disease in Senegal. However, geographic isolation of Bedik ethnic groups challenged implementation of the key elements of the schistosomiasis program in eastern Senegal, and therefore, a hospital was established in Ninefescha to improve access to health care as well as laboratory support for this population.

Coulomb Mediated Hybridization of Excitons in Coupled Quantum Dots.

We report Coulomb mediated hybridization of excitonic states in optically active InGaAs quantum dot molecules. By probing the optical response of an individual quantum dot molecule as a function of the static electric field applied along the molecular axis, we observe unexpected avoided level crossings that do not arise from the dominant single-particle tunnel coupling. We identify a new few-particle coupling mechanism stemming from Coulomb interactions between different neutral exciton states.

[Can we overcome schistosomiasis? A Senegalese example].

The authors report the results of controlling schistosomiasis in 53 villages from Ninefecha area-(Kedougou District, East Senegal) within Schistosomiasis National Control Program partnership. The four aims were: i) praziquantel treatment of 3324 children 6-14 years old, ii) installation of a laboratory for children prevalence annual monitoring (random draw one in three), iii) health education of the concerned people ("sensitization"), iiii) construction of latrines. 900 latrines are required and 649 have been built.

[Can schistosomiasis be defeated? An example from Senegal].

The authors report the results of actions combatting schistosomiasis since 2008 in 53 villages in eastern Senegal, including the creation of 450 latrines and the distribution of praziquentel. The prevalence of Schistosoma mansoni has fallen from 44% in 2006 to 1.8% today.

Interstitial fluid shifts in simulated long-haul flights monitored by a miniature ultrasound device.

Background: Long-haul flights (LHF) are known to be connected with an increased risk of deep vein thrombosis. There is still some lack of clarity about the impact of hypoxia and lower levels of air pressure and humidity on passengers during flight. This cross-over study researched interstitial fluid shifts traced by measurements of tissue thickness (TT) under controlled simulated conditions of a LHF.

Coplanar stripline antenna design for optically detected magnetic resonance on semiconductor quantum dots.

We report on the development and testing of a coplanar stripline antenna that is designed for integration in a magneto-photoluminescence experiment to allow coherent control of individual electron spins confined in single self-assembled semiconductor quantum dots. We discuss the design criteria for such a structure which is multi-functional in the sense that it serves not only as microwave delivery but also as electrical top gate and shadow mask for the single quantum dot spectroscopy. We present test measurements on hydrogenated amorphous silicon, demonstrating electrically detected magnetic resonance using the in-plane component of the oscillating magnetic field created by the coplanar stripline antenna necessary due to the particular geometry of the quantum dot spectroscopy.

The significance of anabolic androgenic steroids in a Swedish prison population.

Use of anabolic androgenic steroids (AAS) has been associated with adverse psychiatric effect, violent behavior, and criminality. The aim of this study was to further investigate the motives for and consequences of AAS use, with focus on violent and antisocial behavior. Fifty-nine prisoners were interviewed on their use of AAS, and their history was mapped with Addiction Severity Index interviews.

Violent crime and substance abuse: a medico-legal comparison between deceased users of anabolic androgenic steroids and abusers of illicit drugs.

Several case reports and survey studies have indicated that abuse of anabolic androgenic steroids (AAS) often leads to increased aggressiveness and feelings of hostility that may occasionally trigger violent behaviour. Other observations indicate that many users of AAS also abuse alcohol and/or various illegal substances. Since substance abuse is a well-known risk factor for violent behaviour, it could be that violence committed by AAS users might, at least in many cases, actually be caused by abuse of other drugs.

Criminality among individuals testing positive for the presence of anabolic androgenic steroids.

Context: Observations suggest that the use of anabolic androgenic steroids (AAS) may trigger uncontrolled, violent rage. Other observations indicate that certain groups of criminals may use AAS with the intention of being capable of committing crime more efficiently.

Objective: To examine the proposed association between the use of AAS and criminality.

[Cardiac T cell lymphoma: a case report].

The authors relate an observation taken on a 17 year-old African girl for a pleural and pericardial infusion that has resisted the treatment of tuberculosis with no HIV infection. Subsequent echocardiographies revealed the quick formation of an infiltration process inside the left ventricle. Death occurred before pericardial histopathology indicated a cardiac T tell non-hodgkin malignant lymphoma.

[Ascites due to constrictive pericarditis].

Introduction: We report a case in which ascites revealed chronic constrictive pericarditis (CCP) of tuberculous origin.

Observation: A 65 year-old man had developed ascites the past over few weeks and oedema of the lower limbs. Treatment was surgical and consisted in pericardiectomy.

Systemic cytokine response in murine anthrax.

Systemic pro-inflammatory cytokine release has been previously implicated as a major death-causing factor in anthrax, however, direct data have been absent. We determined the levels of IL-1 beta, IL-6 and TNF-alpha in serum of mice challenged with virulent (Ames) or attenuated (Sterne) strains of Bacillus anthracis. More than 10-fold increase in the IL-1beta levels was detected in Ames-challenged Balb/c mice, in contrast to more susceptible C57BL/6 mice, which showed no IL-1beta response.
