Seizures of agrochemical formulations have increased in Brazil and Rio Grande do Sul is among the Brazilian states with the highest number of seizures of these products obtained illicitly. The use of illicit formulations can cause significant harm to agricultural production, the environment, and non-target species. This study evaluated the cytotoxicity and oxidative stress of a seized formulation containing the herbicide imazethapyr (IMZT). Characterization of the herbicide included gas chromatography-mass spectrometry (GC-MS) and thermal analyses (thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC)). Hemolytic and cytotoxicity assays in ZF-L hepatic cells showed IC50 values of 12.75 µg/mL, 3.01 µg/mL, 2.67 µg/mL, and 1.61 µg/mL for erythrocytes, [3(4,5-dimethyl)-2 bromide-5 diphenyl tetrazolium] (MTT), neutral red (NR), and lactate dehydrogenase (LDH) assays, respectively. The median IC50 of 2.84 µg/mL was used in oxidative stress assays, revealing increased reactive oxygen species (ROS) production, reduced total sulfhydryl content, and decreased superoxide dismutase (SOD) and catalase (CAT) activity. This study is the first to report in vitro oxidative stress induced by IMZT in the ZF-L cell line, emphasizing the importance of in vitro assays for assessing the toxic effects of seized agrochemicals on human health and the environment.

The deployment of hydrogen as an energy carrier is found to be a vital alternative fuel for the future. It is expected that water electrolysis, powered by renewable energy sources, be able to scale-up hydrogen production. However, the reaction kinetic of oxygen evolution reaction(OER) is a sluggish process, which predominantly limits the efficiency of water electrolysis. This review recapitulates the recent progress and efforts made in the design and development of two selected earth-abundant bimetallic electrocatalysts(Ni Co and Co Fe) for alkaline OER. Each bimetal electrocatalyst is thoroughly outlined and discussed in five sub-sections, including bimetal(oxy) hydroxides, Layered double hydroxides(LDHs) structures,oxides, composites, alloy and nanostructured electrocatalysts, and assembled with ***, a brief introduction to an in situ/operando characterization techniques and advantages for monitoring the structure of the electrocatalysts is provided. Finally, a summary outlining the challenges and conceivable approaches to advance OER performance is highlighted and discussed.

The aim of this study is to assess the results of episcleral brachytherapy as treatment of retinal vasoproliferative tumors(RVTs) in a referral Intraocular Tumors Unit(ITU). A retrospective review of all patients diagnosed with vasoproliferative tumors of the retina and treated with episcleral brachytherapy in the ITU, University Hospital of Valladolid between 2009 and 2015 was done. Five patients accomplished the inclusion criteria. All of them presented associated exudation and secondary retinal detachments(RD). Four patients had received prior treatments. Decreased tumor size and exudation regression was found in all cases after treatment. Visual acuity remained stable or increased in all patients. No recurrences have been found after twelve-months follow up. The results of the present study suggest that episcleral brachytherapy is an efficient and safe option in the management of vasoproliferative tumors, especially when large tumor or extensive subretinal fluid is present. In these cases episcleral brachytherapy could be considered as a first line treatment.

The K/HDEL receptor ERD2 mediates the transport of soluble endoplasmic reticulum （ER）-resident proteins containing a C-terminal K/HDEL signal from the Golgi apparatus back to the ER via COPI （COat Protein I）-coated vesicles. Sorting of ERD2 within COPI vesicles is facilitated by p24 proteins. In Arabidop- sis, p24δ5 has been shown to interact directly with ERD2 via its luminal GOLD （GOLgi Dynamics） domain and with COPI proteins via its cytoplasmic C-terminal tail at the acidic pH of the Golgi apparatus. Several members of the p24 family in mammals and yeast have been shown to be glycosylated, but whether Arabidopsis p24 proteins are glycosylated and the role of the sugar moiety in p24 function remain unclear. Here, we show that Arabidopsis p24δ5 protein is N-glycosylated in its GOLD domain. Furthermore, we demonstrate that this post-translational modification is important for its coupled transport with p241β2 at the ER-Golgi interface, for its interaction with the K/HDEL receptor ERD2, and for retrograde transport of ERD2 and K/HDEL ligands from the Golgi apparatus back to the ER.

Sperm quality is evaluated for the calculation of sperm dosage in artificial reproductive programs. The most common parameter used is motility, but morphology has a higher potential as a predictor of genetic quality. Morphometry calculations from CASA-Morph technology improve morphological evaluation and allow mathematical approaches to the problem. Semen from 28 Holstein bulls was collected by artificial vagina, and several ejaculates were studied. After general evaluation, samples were diluted, packaged in 0.25 ml straws, and stored in liquid nitrogen. Two straws per sample were thawed, and slides were processed and stained with Diff-Quik. Samples were analyzed by a CASA-Morph system for eight morphometric parameters. In addition to the ＂classical＂ statistical approach, based on variance analysis （revealing differences between animals, ejaculates, and straws）, principal component （PC） analysis showed that the variables were grouped into PC1, related to size, and PC2 to shape. Subpopulation structure analysis showed four groups, namely, big, small, short, and narrow from their dominant characteristics, representing 31.0%, 27.3%, 24.1%, and 17.7% of the total population, respectively. The distributions varied between animals and ejaculates, but between straws, there were no differences in only four animals. This modern approach of considering an ejaculate sperm population as divided into subpopulations reflecting quantifiable parameters generated by CASA-Morph systems technology opens a new view on sperm function. This is the first study applying this approach to evaluate different ejaculates and straws from the same individual. More work must be done to improve seminal dose calculations in assisted reproductive programs.

Up to now, ecology has a strong influence on the development of technical and instrumental aspects of architecture, such as renewable and efficient of resources and energy, COz emissions, air quality, water reuse, some social and economical aspects. These concepts define the physical keys and codes of the current ＇sustainable＇ architecture, normally instrumental but rarely and insufficiently theorised. But is not there another way of bringing us to nature？ We need a theoretical referent. This is where we place the Van der Laan＇s thoughts： he considers that art completes nature and he builds his theoretical discourse on it, trying to better understand many aspects of architecture. From a conceptual point of view, we find in his works sense of timelessness, universality, special attention on the ＇locus＇ and a strict sense of proportions and use of materials according to nature. Could these concepts complement our current sustainable architecture？ How did Laan apply the current codes of ecology in his architecture？ His work may help us to get a theoretical interpretation of nature and not only physical. This paper develops this idea through the comparison of thoughts and works of Laan with the current technical approach to ＇sustainable＇ architecture.
