| Venoms from snakes of the Bothrops genus are proteolytic, coagulant, hemorrhagic and nephrotoxic, causing edema, necrosis, hemorrhage and intense pain at the bite site, besides systemic alterations. Many adjuvants have been added to the venom used in the sensitization of antiserum-producer animals to increase antigenic induction and reduce the envenomation pathological effects. Gamma radiation from 60Co has been used as an attenuating agent of the venoms toxic properties. The main objective was to study, comparatively, clinical and laboratory aspects of goats inoculated with bothropic (Bothrops jararaca) venom, natural and irradiated from a 60Co source. Twelve goats were divided into two groups of six animals: GINV, inoculated with 0.5mg/kg of natural... |

| ABSTRACT Dehydration of plant products extends its shelf life and reduces its mass and volume, which increases transport and storage efficiency and adds value to food. However, it is an intensive process in energy and time, making necessary the search for more efficient technologies, Thus, this study aimed to investigate the infrared ginger dehydration process by approaching the constant period of dehydration to the theory of mass and heat transfer process to the wet bulb thermometer and the decreasing period of dehydration to liquid diffusion theory. We submitted 5.0 mm thickness and 2.0 cm diameter slices to a dryer with infrared radiation at 50, 60, 70, 80, 90 and 100 °C until constant mass. Heat and mass transfer coefficients, and effective diffusion... |

| In this study, two site-specific solar radiation (Rs) and net radiation (Rn) based equations for estimating reference evapotranspiration (ET0) were developed and their performance were statistically analysed in comparison to widely accepted FAO Penman-Monteith method (PMF-56) and four other standard radiation methods for sub-humid Hazaribagh region of Jharkhand. These two equations were developed with daily values of Rs and Rn in conjunction with maximum and minimum air temperature by taking daily PMF-56 ET0 values as index with weather dataset of 15 years (1990-2004). The performance of these equations validated with carefully screened daily weather dataset of eight years (2005-2012) with other considered standard methods revealed that they estimated ET0... |

| The objective of the present study was to evaluate the effects of different dietary energy levels and stocking densities on the thermoregulating parameters, live performance, and carcass traits of broilers reared under tropical winter conditions at different times of the day. In total, 1,312 one-d-old male broilers were used. Birds were allotted to three different stocking densities (10, 14 or 18 birds/m²) and two dietary energy levels (2900 or 3200 kcal ME/kg). The following parameters were evaluated:radiant heat load (RHL), rectal temperature (RT), feed intake (FI), weight gain (WG), feed conversion ratio (FCR), livability (L), production of live weight per area (WA), and carcass yield. Stocking density did not affect sensible heat loss (SRL) or rectal... |

| Radiation therapy of the brain is associated with many consequences, including cognitive disorders. Pathogenesis of radiation induced cognitive disorder is not clear, but reduction of neurogenesis in hippocampus may be an underlying reason. 24 adult male rats entered to study. Radiation absorbed dose to midbrain was 10 Gy, delivered by routine cobalt radiotherapy machine which its output was measured 115.24 cGy/min. The rats were divided in four groups of sixes, including groups of control, single fraction 10 Gy, fractionated 10 Gy and finally anaesthesia sham group. Number of pyramidal nerve cells was counted in two regions of hippocampus formation (CA1 and CA3). The radiation could reduce the number of cells in two regions of hippocampus significantly... |

| Period2 is a core circadian gene, which not only maintains the circadian rhythm of cells but also regulates some organic functions. We investigated the effects of mPeriod2 (mPer2) expression on radiosensitivity in normal mouse cells exposed to 60Co-γ-rays. NIH 3T3 cells were treated with 12-O-tetradecanoylphorbol-13-acetate (TPA) to induce endogenous mPer2 expression or transfected with pcDNA3.1(+)-mPer2 and irradiated with 60Co-γ-rays, and then analyzed by several methods such as flow cytometry, colony formation assay, RT-PCR, and immunohistochemistry. Flow cytometry and colony formation assay revealed that irradiated NIH 3T3 cells expressing high levels of mPer2 showed a lower death rate (TPA: 24 h 4.3% vs 12 h 6.8% and control 9.4%; transfection:... |

| Warmer and drier climates over Amazonia have been predicted for the next century with expected changes in regional water and carbon cycles. We examined the impact of interannual and seasonal variations in climate conditions on ecosystem-level evapotranspiration (ET) and water use efficiency (WUE) to determine key climatic drivers and anticipate the response of these ecosystems to climate change. We used daily climate and eddyflux data recorded at the Guyaflux site in French Guiana from 2004 to 2014. ET and WUE exhibited weak interannual variability. The main climatic driver of ET and WUE was global radiation (Rg), but relative extractable water (REW) and soil temperature (Ts) did also contribute. At the seasonal scale, ET and WUE showed a modal pattern... |

| Mathematical models were tested to correlate the leaf area index (LAI) of maize to the percentage of light intercepted by the canopy (% LIC) and this with the total dry matter of aerial parts (TDM), as well with the grain yield (GY). The experiment was conducted in a randomized block design, with four replications. The treatments consisted of hybrid maize at five plant densities: 4.0, 2.66, 2.0, 1.6, and 1.3 plants per m2 (pl m-2). At densities of 4.0 and 2.66 pl m-2, the average LAI and TDM did not differ among themselves but were significantly higher than those presented at the densities of 2.0, 1.66 and 1.3 pl m-2, which also did not differ among themselves. The number of corncobs per plant (cob pl-1) and GY behaved similarly. The LAI grew exponentially... |

| During surveys of dying vegetation in natural ecosystems and associated waterways in Australia many new taxa have been identified from Phytophthora ITS Clade 6. For representative isolates, the region spanning the internal transcribed spacer region of the ribosomal DNA, the nuclear gene encoding heat shock protein 90 and the mitochondrial cox1 gene were PCR amplified and sequenced. Based on phylogenetic analysis and morphological and physiological comparison, four species and one informally designated taxon have been described; Phytophthora gibbosa, P. gregata, P. litoralis, P. thermophila and P. taxon paludosa. Phytophthora gibbosa, P. gregata and P. taxon paludosa form a new cluster and share a common ancestor; they are homothallic and generally... |

| The anti-inflammatory effect of dexamethasone on the irradiated kidneys of adult Wistar rats (Rattus norvegicus) was studied. Eighteen adult Wistar rats were, after acclimatization, randomly divided into 3 groups of 6 animals per group. The control group had normal saline, receiving neither drugs nor radiation. The second group received normal saline and radiation. The third group received pretreatment with dexamethasone at 1mg/kg body weight/day for 2 days followed by radiation. Radiation was delivered to the animals as a single fraction of 2.5 Gy of gamma rays from Cobalt-60 source, using an AECL Theatron 780-C Teletherapy machine. After exposure to the different interventions, the animals were sacrificed on the 14th post-irradiation day and the kidneys... |

| ABSTRACT: Our retrospective study evaluated the survival of 24 dogs with unresectable malignant melanoma treated with radiation therapy. Fifteen dogs were treated with radiation therapy (RT) and chemotherapy (CT), five with surgery followed by RT and CT, three with palliative RT, and one with electrochemotherapy associated with RT. All dogs were treated with an orthovoltage Stabilipan I. The protocol used was three or four weekly fractions of 8 Gy. Carboplatin was administered every 21 days, a total of four times. Five percent of dogs were classified as having stage I melanoma, 17% as stage II, 50% as stage III, and 17% as stage IV. Sixty-four percent had a partial response to treatment, 29% achieved complete remission, and 7% remained in a stable disease... |
