This study evaluated the use of cooled semen in a fixed-time artificial insemination (FTAI) program compared with frozen–thawed semen to improve pregnancy rates in beef cattle. Ejaculates of three bulls were collected and divided into two treatments: (1) frozen–thawed semen and (2) cooled semen. Egg-yolk extender without glycerol was used for the cooled semen treatment. Straws (25 × 106 spermatozoa) were submitted to cooling for preservation at 5°C for 24 h, after which FTAI was performed. Nelore cows ( ...

Rapid diagnostics is pivotal to curb SARS-CoV-2 transmission, and saliva has emerged as a practical alternative to naso/oropharyngeal (NOP) specimens. We aimed to develop a direct RT-LAMP (reverse transcription loop-mediated isothermal amplification) workflow for viral detection in saliva, and to provide more information regarding its potential in curbing COVID-19 transmission. Clinical and contrived specimens were used to optimize formulations and sample processing protocols. Salivary viral load ...

Abstract Background Trypanosoma cruzi is the etiological agent of Chagas disease (CD) or American trypanosomiasis, an important public health problem in Latin America. Benznidazole (BZ), a drug available for its treatment, has limited efficacy and significant side effects. Essential oils (EOs) have demonstrated trypanocidal activity and may constitute a therapeutic alternative. Our aim was to evaluate the efficacy of the EOs of clove (CEO - Syzygium aromaticum ) and ginger (GEO - Zingiber officinale ), administered ...

The reaction of oxidation of 2-propanol to acetone in the presence of NADP catalyzed by Thermoanaerobium brockii alcohol dehydrogenase (TBADH) has been studied for gaining insight into the coupled-substrate approach that has been extensively used for NADPH regeneration in preparative-scale reductions catalyzed by this enzyme. The data obtained in initial velocity experiments in the absence of products as well as those involving product inhibition and dead-end inhibition by pyrazole suggest that the ...

Abstract Background Impaired fertility in cattle limits the efficiency of livestock production systems. Unraveling the genetic architecture of fertility traits would facilitate their improvement by selection. In this study, we characterized SNP chip haplotypes at QTL blocks then used whole-genome sequencing to fine map genomic regions associated with reproduction in a population of Nellore ( Bos indicus ) heifers. Methods The dataset comprised of 1337 heifers genotyped using a GeneSeek® Genomic Profiler ...

A liquid chromatography–electrospray ionization tandem mass spectrometry (HPLC–ESI-MS/MS) method for the simultaneous quantitation of artemether and lumefantrine in human plasma was developed and validated. Artesunate was used as an internal standard (IS). The analytes were extracted by a protein precipitation procedure and separated on a reversed-phase Zorbax SB-Ciano column with a mobile phase composed of methanol and 10 mM aqueous ammonium acetate containing 0.2% (v/v) acetic acid and 0.1% (v/v) ...

However, the mite fauna from this biome are still poorly known. Here, we present a checklist of mite species on Astronium fraxinifolium Schott, a Brazilian plant species threatened with extinction, from the Cerrado remnants associated with nickel mining areas, in the Niquelândia ...

Nowadays, one of the financial and environmental problems faced by cities is related to the adequate final disposal of solid waste in municipal sanitary landfills. The selection of the areas implies in several factors as the proximity of watercourses, soil resistance to contaminating effects, protection of conservation areas, size of the area available, distance between collection and disposal, which are the main issues that make the topic relevant. Thereby, was employed a methodology to assess ...

The authors describe the case of a 71-year-old female patient who initially went to the dermatologist to assess a scalp skin tumor. This lesion was submitted to an incisional biopsy, performed by dermatologist herself, and the result of the anatomopathological examination and immunohistochemical study showed a preliminary diagnosis of metastasis of breast carcinoma. The patient had no history of breast cancer and, in view of this result, she was referred to consult with the mastologist, who carried ...

The application of synthetic insecticides is the main strategy used to reduce the damage caused by the diamondback moth Plutella xylostella in commercial Brassica crops. However, incorrect insecticide use can cause biological and ecological disturbances in agroecosystems. Cycloneda sanguinea is a generalist voracious predator and is distributed widely in cultivated and noncultivated ecosystems. This study investigated the efficiency of four insecticides for the control of P. xylostella and the lethal ...
