Moisture is required for the termination of egg diapause in the chrysomelid beetle, Homichloda barkeri

Four factors (moisture, light regime, temperature, food type) were examined for their effects on the embryonic diapause of Homichloda (Weiseana) barkeri (Jacoby) (Coleoptera: Chrysomelidae), a biocontrol agent for prickly acacia, Acacia nilotica (L.) Willdenew ex Delile (Mimosaceae). Moisture is critical for termination of diapause. A single wetting of eggs resulted in a low hatch rate while a sequence of wetting events followed by periods of dryness produced a high hatch rate. A relatively constant proportion of embryos within each batch initiated development at each wetting event, with hatching complete after the eighth wetting event in these trials. An extended interval between wetting events, tested at up to 23 days, did not result in a decreased overall hatch rate. A threshold time of exposure to moisture of between 3 to 6 h is required before development proceeds. The response of eggs to the moisture regime is seen as a strategy for taking advantage of available food after rainfall by terminating diapause, rather than merely a quiescent response to the absence of moisture. Temperature affected development time and the proportion of eggs that developed. Experimental manipulations of photoperiod and host-plant availability showed no effect on embryonic development.

Patrocinio de programas de actividad física por parte de la industria de bebidas azucaradas: ¿salud pública o relaciones públicas?

La creciente evidencia acerca de los vínculos entre consumo de bebidas azucaradas, obesidad y otras enfermedades crónicas plantea la necesidad de implementar acciones políticas que transciendan las intervenciones centradas exclusivamente en la responsabilidad individual. Temiendo que ello afecte sus objetivos comerciales en América Latina, la industria de bebidas azucaradas lleva a cabo un intenso cabildeo político en altas esferas gubernamentales de la región. Esta estrategia esta acompañada de los llamados programas de responsabilidad social empresarial dirigidos a financiar iniciativas que promocionan la actividad física. Estos esfuerzos, aparentemente altruistas, están dirigidos a mejorar la imagen pública de esta industria y a lograr mayor influencia política ante regulaciones contrarias a sus intereses. Si este sector de la industria desea contribuir con el bienestar humano, como públicamente lo expresa, debería evitar obstruir iniciativas legislativas dirigidas a regular la comercialización, mercadeo y oferta de sus productos.

The inositol Inpp5k 5-phosphatase affects osmoregulation through the vasopressin-aquaporin 2 pathway in the collecting system.

Inositol Inpp5k (or Pps, SKIP) is a member of the inositol polyphosphate 5-phosphatases family with a poorly characterized function in vivo. In this study, we explored the function of this inositol 5-phosphatase in mice and cells overexpressing the 42-kDa mouse Inpp5k protein. Inpp5k transgenic mice present defects in water metabolism characterized by a reduced plasma osmolality at baseline, a delayed urinary water excretion following a water load, and an increased acute response to vasopressin. These defects are associated with the expression of the Inpp5k transgene in renal collecting ducts and with alterations in the arginine vasopressin/aquaporin-2 signalling pathway in this tubular segment. Analysis in a mouse collecting duct mCCD cell line revealed that Inpp5k overexpression leads to increased expression of the arginine vasopressin receptor type 2 and increased cAMP response to arginine vasopressin, providing a basis for increased aquaporin-2 expression and plasma membrane localization with increased osmotically induced water transport. Altogether, our results indicate that Inpp5k 5-phosphatase is important for the control of the arginine vasopressin/aquaporin-2 signalling pathway and water transport in kidney collecting ducts.

A new species of Aristobrotica Bechynéand a checklist of the genus (Coleoptera, Chrysomelidae, Galerucinae)

A new species of Aristobrotica Bechynéand a checklist of the genus (Coleoptera, Chrysomelidae, Galerucinae). A new neotropical species of the Section Diabroticites (Luperini, Diabroticina) is described and illustrated. Aristobrotica capillosa sp. nov., from the state of Amazonas, northern Brazil, is the only species of the genus with elytra densely covered by erect hairs. The genus Aristobrotica Bechyné, 1956 now comprises 17 species, with only one occurring in Central America, Aristobrotica allardi (Jacoby, 1887) from Panama, and the remaining 16 are South American. A checklist of Aristobrotica species and their geographic distribution is also provided.

Intravenous immunoglobulin for treatment of mild-to-moderate Alzheimer's disease: a phase 2, randomised, double-blind, placebo-controlled, dose-finding trial.

BACKGROUND: Three small trials suggest that intravenous immunoglobulin can affect biomarkers and symptoms of mild-to-moderate Alzheimer's disease. We tested the safety, effective dose, and infusion interval of intravenous immunoglobulin in such patients. METHODS: We did a multicentre, placebo-controlled phase 2 trial at seven sites in the USA and five in Germany. Participants with probable Alzheimer's disease aged 50-85 years were randomly assigned (by a computer-generated randomisation sequence, with block sizes of eight) to infusions every 4 weeks (0·2, 0·5, or 0·8 g intravenous immunoglobulin per kg bodyweight, or placebo) or infusions every 2 weeks (0·1, 0·25, or 0·4 g/kg, or placebo). Patients, caregivers, investigators assessing outcomes, and staff at imaging facilities and the clinical research organisation were masked to treatment allocation, but dispensing pharmacists, the statistician, and the person responsible for final PET analyses were not. Treatment was masked with opaque pouches and infusion lines. The primary endpoint was median area under the curve (AUC) of plasma amyloid β (Aβ)(1-40) between the last infusion and the final visit (2 weeks or 4 weeks depending on infusion interval) in the intention-to-treat population. The trial is registered at ClinicalTrials.gov (NCT00812565) and controlled-trials.com (ISRCTN64846759). FINDINGS: 89 patients were assessed for eligibility, of whom 58 were enrolled and 55 included in the primary analysis. Median AUC of plasma Aβ(1-40) was not significantly different for intravenous immunoglobulin compared with placebo for five of the six intervention groups (-18·0 [range -1347·0 to 1068·5] for 0·2 g/kg, -364·3 [-5834·5 to 1953·5] for 0·5 g/kg, and -351·8 [-1084·0 to 936·5] for 0·8 g/kg every 4 weeks vs -116·3 [-1379·0 to 5266·0] for placebo; and -13·8 [-1729·0 to 307·0] for 0·1 g/kg, and -32·5 [-1102·5 to 451·5] for 0·25 g/kg every 2 weeks vs 159·5 [51·5 to 303·0] for placebo; p>0·05 for all). The difference in median AUC of plasma Aβ(1-40) between the 0·4 g/kg every 2 weeks group (47·0 [range -341·0 to 72·5]) and the placebo group was significant (p=0·0216). 25 of 42 (60%) patients in the intervention group versus nine of 14 (64%) receiving placebo had an adverse event. Four of 42 (10%) patients in the intravenous immunoglobulin group versus four of 14 (29%) receiving placebo had a serious adverse event, including one stroke in the intervention group. INTERPRETATION: Intravenous immunoglobulin may have an acceptable safety profile. Our results did not accord with those from previous studies. Longer trials with greater power are needed to assess the cognitive and functional effects of intravenous immunoglobulin in patients with Alzheimer's disease.

Modeling the Transport Sector: The Role of Existing Fuel Taxes in Climate Policy

Existing fuel taxes play a major role in determining the welfare effects of exempting the transportation sector from measures to control greenhouse gases. To study this phenomenon we modify the MIT Emissions Prediction and Policy Analysis (EPPA) model to disaggregate the household transportation sector. This improvement requires an extension of the GTAP data set that underlies the model. The revised and extended facility is then used to compare economic costs of cap-and-trade systems differentiated by sector, focusing on two regions: the USA where the fuel taxes are low, and Europe where the fuel taxes are high. We find that the interplay between carbon policies and pre-existing taxes leads to different results in these regions: in the USA exemption of transport from such a system would increase the welfare cost of achieving a national emissions target, while in Europe such exemptions will correct pre-existing distortions and reduce the cost.

Análisis de los conceptos de la cadena de suministro y su relación con el desempeño organizacional

En el contexto de globalización, cambio y entornos más agresivos para las organizaciones, se hace necesario conocer el impacto de la administración de la cadena de suministro en el desempeño organizacional y cómo el fortalecimiento de la cadena permite a las organizaciones mantenerse en el mercado (Jacoby, 2009). Esta tendencia aplica para las organizaciones en todo el mundo, en el caso de las organizaciones Colombianas se requiere un trabajo académico donde se haga un análisis de los impactos de las cadenas de suministro en el desempeño organizacional (Ministerio de Transporte, Ministerio de Comercio, DIAN, & DNP, 2008). Una muestra de lo anterior es el hecho de que Colombia se encuentra en el puesto 97 en el ranking de desempeño logístico hecho por el Banco Mundial en 2014 (Banco Mundial, 2014). Esto demuestra la necesidad de mejorar los procesos logísticos en el país mediante el fortalecimiento de las cadenas de suministros, permitiendo una mayor eficiencia y capacidad de respuesta ante las demandas globales de los diferentes mercados en un entorno cambiante y agresivo. Por lo anterior se debe comprender y dimensionar el potencial impacto que tenga el desempeño organizacional y la correcta gestión de la cadena de suministros en el contexto Colombiano. Por consiguiente a través de una exhaustiva revisión literaria se buscaran los puntos de convergencia entre el desempeño organizacional y la cadena de suministros, haciendo uso del modelo Balance Score Card para analizar desde las perspectivas financiera, clientes, procesos internos e innovación y aprendizaje de las organizaciones, las actividades que involucran las cadena de suministro: aprovisionamiento, producción y distribución.
