  2. Article ; Online: Seabird guano inputs increase impacts from introduced mammals on the native plants and animals of an oceanic island.

    Espíndola, Walter D / Carlo, Tomás A

    Abstract Seabirds create fluxes of nutrients from marine to terrestrial ecosystems that influence the food webs of small islands. We investigated how guano inputs shape terrestrial food webs by comparing species of selected plant and animal species in a red-footed booby colony in Mona Island (Puerto Rico, Caribbean Sea), to sites of the island lacking guano inputs. We quantified guano deposition and its relationship to plant biomass production, fecundity and density, as well as the activity of native and introduced animal species. In general, guano inputs increased the gross primary plant productivity, size, and fecundity by twofold. Guano inputs were also associated with twofold increases in density of Anole lizards, but also to increases in the activity of introduced pigs (> 500%), goats (> 30%), and cats (> 500%), which negatively impact native species. In particular, elevated pig and cat activity within the booby colony was correlated with lower activity of endemic ground lizards and of introduced rats. Our results also suggest that severe droughts associated with climate change exacerbate the negative effects that introduced species have on vegetation and reduce the positive effects of seabird guano inputs. Our findings underscore the importance of allochthonous guano inputs in subsidizing plant productivity and native and endemic species in small oceanic islands, but also in increasing the negative impacts of introduced mammals. Management and conservation efforts should focus on the exclusion (or eradication) of introduced mammals, particularly pigs and goats, from remnant seabird colonies in Mona Island.

    Abstract Incapacitating agents are chemical weapons that produce a temporary disabling condition that persists for hours or days after exposure. Their main site of action is the central nervous system and includes substances that are considered depressants or stimulants. While not intended to cause death, can produce significant morbidity in affected patients. The objective of this narrative review is to update the toxicokinetics, toxicodynamics, diagnosis, and treatment of these chemicals, considering that 20 years have passed since the Nord Ost Siege, where a fentanyl derivative was used by Russian forces to neutralize a group of Chechen dissidents. A bibliographic search was carried out in PubMed, SciELO, and Cochrane Library databases as well as nonindexed scientific literature.

    Abstract Type 2 diabetes (T2D) and obesity have reached epidemic proportions. Incretin therapy is the second line of treatment for T2D, improving both blood glucose regulation and weight loss. Glucagon-like peptide-1 (GLP-1) and glucose-stimulated insulinotropic polypeptide (GIP) are the incretin hormones that provide the foundations for these drugs. While these therapies have been highly effective for some, the results are variable. Incretin therapies target the class B G protein-coupled receptors GLP-1R and GIPR, expressed mainly in the pancreas and the hypothalamus, while some therapeutical approaches include additional targeting of the related glucagon receptor (GCGR) in the liver. The proper functioning of these receptors is crucial for incretin therapy success and here we review several mechanisms at the cellular and molecular level that influence an individual's response to incretin therapy.

    Abstract We introduce a fully ab initio theory for inelastic scattering of any atom from any surface exciting single phonons, and apply the theory to helium scattering from Nb(100). The key aspect making our approach general is a direct first-principles evaluation of the scattering atom-electron vertex. By correcting misleading results from current state-of-the-art theories, this fully ab initio approach will be critical in guiding and interpreting experiments that adopt next-generation, nondestructive atomic beam scattering.

    Abstract A 52-year-old man sustained an injury to the right wrist following a fall into a push-up position. Direct-access outpatient physical therapy evaluation was performed 24 hours after the injury. A scaphoid radiograph series, consistent with American College of Radiology guidelines, was obtained based upon examination findings. The radiographs revealed a scapholunate gap of 4 mm and a scapholunate angle of greater than 60°, suggestive of scapholunate dissociation.

    Abstract Este artículo analiza protestas plebeyas, sus formas de expresión, impactos, consecuencias y tendencias en una perspectiva histórica de larga duración. Con frecuencia, constituían formas reactivas de acciones contra usurpaciones que habían sido previamente protagonizadas por poderosos locales y faccio- nes sociales que no respetaban usos comunitarios consuetudinariamente legi- timados, así como derechos de disfrute de recursos naturales. En ocasiones las usurpaciones estuvieron amparadas por privilegios regios concedidos a empresarios para aprovechar estos recursos en beneficio propio y de la Co- rona. Las reacciones contra estas prácticas (tenidas por ilícitas) conformaban variadas formas de participación política plebeya en las controversias sobre cómo utilizar las reservas y recursos. Estos conflictos expresaban valores éticos comunitarios que dotaban de legitimidad a tumultos o alborotos, incendios fo- restales o variantes de insubordinación o furtivismo. Así, una cultura plebeya, vigorosa en las sociedades rurales del Antiguo Régimen, articulaba formas de disciplina social ejercidas desde abajo.

    Abstract This study aimed to determine and describe the prevalence of combination antibiotics dispensed in outpatients with health insurance in Syria. Data on all dispensed medicines between June 2018 and May 2019 for 81,314 adults were obtained, and medicines belonging to the J01 group of the World Health Organization (WHO) anatomical therapeutic classification (ATC) were included in the analysis. Prescriptions were stratified according to the number of antibiotics, age, and sex. Antibiotic utilization was expressed as the number of prescriptions per 1000 persons per year. Out of 59,404 prescriptions for antibiotics, 14.98% contained antibiotic combinations, distributed to 22.49% of the patients. The prevalence of dispensing antibiotic combinations was higher in female patients (23.00%), and the youngest (18-30 years, 26.19%) and oldest age groups (>70 years, 25.19%). The antibiotics most commonly combined were co-amoxiclav, second- and third-generation cephalosporins, and macrolides. Over 60% of the combinations contained ceftriaxone alone or in combination with sulbactam. The present study shows an alarmingly widespread prescription of antibiotic combinations, posing a risk to global health by promoting resistance development.
