| As an essential micronutrient, iron plays a key role in oceanic biogeochemistry. It is therefore linked to the global carbon cycle and climate. Here, we report a dissolved iron (DFe) isotope section in the South Atlantic and Southern Ocean. Throughout the section, a striking DFe isotope minimum (light iron) is observed at intermediate depths (200–1,300 m), contrasting with heavier isotopic composition in deep waters. This unambiguously demonstrates distinct DFe sources and processes dominating the iron cycle in the intermediate and deep layers, a feature impossible to see with only iron concentration data largely used thus far in chemical oceanography. At intermediate depths, the data suggest that the dominant DFe sources are linked to organic matter... |

| Several dairy farms still have old multi-span barns which are encountering several problems in summer and they are: low ventilation rates, non-uniformed air distribution, heat stress and high indoor concentrations of harmful gases. A solution has been suggested, in this study, which is refurbishing the roofs of old multi-span dairy barns by modifying the roof design, increasing the cowshed height and the roof slope angle. In order to implement this new roof design, rigorous experimental measurements and theoretical calculations were carried out to evaluate the indoor environment before and after refurbishment which was determined by measuring and estimating the following parameters: air exchange rate, indoor temperature, gaseous concentrations (NH3, CH4,... |

| Cats are the only definitive hosts of Toxoplasma gondii and constitute an essential source of infection to all warm blooded animals and humans. Diagnosis of T gondii infection in cats is fundamental for proper management and control of infection in humans and animals. In the current study, we have evaluated the diagnostic performance of tachyzoite lysate antigen (TLA) and different T. gondii recombinant antigens including surface antigen 2 (SAG2), dense granule proteins 2, 6, 7, 15 (GRA2, GRA6, GRA7, GRA15) and microneme 10 protein (MIC10) in immunoglobulin G enzyme linked-immunosorbent assay (IgG ELISA) using cat serum samples, with reference to latex agglutination test (LAT). Remarkably, TLA showed better performance than other recombinant antigens in... |

| In the asexual stages, Toxoplasma gondii stage converts between acute phase rapidly replicating tachyzoites and chronic phase slowly dividing bradyzoites. Correspondingly, T. gondii differentially expresses two distinct genes and isoforms of the lactate dehydrogenase enzyme, expressing LDH1 exclusively in the tachyzoite stage and LDH2 preferentially in the bradyzoite stage. LDH catalyzes the interconversion of pyruvate and lactate in anaerobic growth conditions and is utilized for energy supply, however, the precise role of LDH1 and LDH2 in parasite biology in the asexual stages is still unclear. Here, we investigated the biological role of LDH1 and LDH2 in the asexual stages, and the vaccine strain potential of deletion mutants lacking LDH1, LDH2, or both... |

| Halphabarol, the active principle of Proximol, is the most potent of the four antispasmodics present in the national desert weed Cymbopogon proximus or ''Halfa Bar''. Halphabarol is of great value for the management of renal colic and in the expulsion of ureteric calculi as it causes dilation of the ureter below the site of calculus while active propulsion is maintained. Evaluation the congenital malformation of proximol in pregnant albino rats during gestation period. The virgin female rats were mated with male rats and the pregnant rats were orally administered a human equivalent dose (0.05 mg/kg) of Proximol from 5th-20th gestation day. At day 20 of pregnancy, all rats were anesthetized to obtained maternal and fetal data. The treatment group displayed... |

| ABSTRACT Bitter gourd is of great importance due to its usage against the treatment of numerous ailments in human beings. A comprehensive survey at four localities of Southern Punjab, Pakistan was carried out to determine the severity of Myrothecium leaf spot. Maximum disease severity was at C1 (Chak 11/NP) and least at C2 (Kot Mehtab). Among isolated species Myrothecium roridum was found more prevalent and pathogenic as compared to M. verrucaria. Antifungal activity using solvent extracts of five medicinal plants (Mangifera indica, Melia azedarach, Nicotiana tabacum, Moringa oleifera and Eucalyptus globosum) were evaluated against isolated species by agar well diffusion method at various concentrations (0.01, 0.10, 1.0 and 10.0 µg / mL). N. tabacum... |

| Exposure of the toxin-producing dinoflagellate Alexandrium catenella (A. catenella) was previously demonstrated to cause apoptosis of hemocytes in the oyster species Crassostrea gigas. In this work, a coumarin-labeled saxitoxin appeared to spread throughout the cytoplasm of the hemocytes. PSTs, including saxitoxin, were also shown to be directly responsible for inducing apoptosis in hemocytes, a process dependent on caspase activation and independent of reactive oxygen species (ROS) production. A series of in vitro labeling and microscopy experiments revealed that STX and analogs there of induced nuclear condensation, phosphatidylserine exposure, membrane permeability, and DNA fragmentation of hemocytes. Unlike in vertebrates, gonyautoxin-5 (GTX5), which... |

| Platelet-rich plasma (PRP) has an important role in musculoskeletal surgery; however, it has been underutilized for accelerating the healing of abdominal wall defects in veterinary practice. Therefore, the aim of this study was to evaluate the use of commercial polyester/cotton fabric (Damour) as a new composite mesh for the repair of experimentally induced abdominal wall defects in canine models, and to investigate the possible role of PRP for improving such repair and reducing allied complications. For this purpose, abdominal wall defects were created in 24 healthy mongrel dogs and then repaired with mesh alone (control group) or mesh and allogenic PRP (PRP group). Dogs were euthanized after 2 or 4 months for gross examination of implantation site,... |

| The Mediterranean region is a climate hot spot, sensitive not only to global warming but also to water availability. In this work we document major temperature and precipitation changes in the Iberian Peninsula and margin during the last 2000 years and propose an interplay of the North Atlantic internal variability with the three atmospheric circulation modes (ACMs), (North Atlantic Oscillation (NAO), east atlantic (EA) and Scandinavia (SCAND)) to explain the detected climate variability. We present reconstructions of sea surface temperature (SST derived from alkenones) and on-land precipitation (estimated from higher plant n-alkanes and pollen data) in sedimentary sequences recovered along the Iberian Margin between the south of Portugal (Algarve) and the... |

| O crescimento da vegetação está relacionado com a disponibilidade de recursos naturais e a capacidade de cada espécie em utilizá-los. Por isso, o objetivo deste estudo foi avaliar o crescimento de dois grupos arbóreos: Grupo 1, correspondente a espécie Araucaria angustifolia; e Grupo 2, representado pelas dez espécies com maior valor de importância em uma Floresta Ombrófila Mista. Para isso, as seguintes hipóteses foram formuladas: a Araucaria angustifolia apresenta crescimento diferenciado das espécies mais representativas em função de características ambientais em que está localizada? e quais locais podem ser prioritários para o manejo dessa espécie? Este estudo foi realizado na Floresta Nacional de São Francisco de Paula, estado do Rio Grande do Sul,... |

| A videira em região tropical necessita de cuidados diferenciados, quando comparada às regiões de clima temperado, principalmente em relação ao manejo da copa. Objetivou-se com este trabalho avaliar a produtividade e a qualidade dos frutos, influenciados por diferentes épocas de poda aliadas a doses de Ethephon, em duas safras da videira Isabel. O delineamento foi inteiramente casualizado, com dezesseis tratamentos no esquema fatorial 4 x 4, com quatro repetições. O primeiro fator foi composto pelas épocas de poda: na safra de inverno (08/março, 22/março, 05/abril e 19/abril de 2013); na safra de verão (25/agosto, 08/setembro, 22/setembro e 06/outubro de 2013). O segundo fator consistiu em quatro concentrações de Ethephon (0, 720, 1440, 2160 mg i.a. L-1).... |
