Ricinus communis L. is a globally relevant industrial oilseed crop mostly cultivated in tropical arid/semi-arid areas, where abiotic stresses frequently limit crop establishment and productivity. Superoxide dismutase (SOD) is an antioxidant enzyme acting as a primary defense against oxidative stress in plants subjected to abiotic stresses, localized in various subcellular compartments, and classified in eukaryotes according to metal cofactors.

The developmental origins of health and disease (DOHaD) concept suggests that adverse conditions during gestation can influence the development and function of multiple organs, including the gastrointestinal tract. Maternal protein restriction (MPR) exposure has been associated with negative effects on reproduction, the endocrine system, and liver metabolic health. However, limited research has explored the impact of MPR on the offspring's intestinal morphophysiology.

The diagnosis of canine visceral leishmaniasis (CVL) presents a challenge due to a variety of non-specific clinical signs. The available tests have low sensitivity. This study aimed to standardize and evaluate the loop-mediated isothermal amplification technique with K26 target (K26-LAMP) for diagnosis of CVL in conjunctival swab (CS) DNA samples extracted through a silica column commercial kit (SW-kit) and boiling (SW-DB) and to compare sensitivity with conventional PCR (kDNA-cPCR) and quantitative real-time PCR (18S-qPCR).

Despite being considered a strictly human disease, there are reports in the literature about animals with confirmed presence of the virus. Owing to the scarcity of scientific literature on the potential for infection of animals and their importance for One Health, the objective of this work was to research SARS-CoV-2 RNA in felines (Felis silvestris catus) and dogs (Canis lupus familiaris) domiciled.

Methods: Cross-cultural adaptation was performed based on the combined guidelines of the World Health Organization's (WHO) Translation Recommendations and the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN). The process included five stages: a) Translation of the instrument into BP by a translator specialized in the construct and a non-specialist, both native BP speakers and fluent in English; b) Synthesis of the two translations by consensus; c) Back-translation by a translator specialized in the construct and a non-specialist, both native English speakers and fluent in BP; d) Analysis by a committee of five speech-language pathologists voice specialist and the creation of the final version; e) Pre-testing with 21 individuals from the target population, conducted virtually.

Hematite has been used as a pigment since ancient times, due to its natural abundance and colour that ranges from vivid red to purple. Caput mortuum is a purple α-FeO whose colour has been ascribed as originating from particle size. In this work, submicrometric synthetic, natural and commercial hematites were investigated by diffuse reflectance spectroscopy (DRS), scanning electron microscopy with energy dispersive spectroscopy (SEM-EDS) and Raman microscopy aiming to clarify the origin of the purple colour.

Therefore, susceptible to generating reactive oxygen species (ROS) and subsequent oxidative stress, compromising cell metabolism upon seed imbibition and germination, seedling and crop establishment, and yield. The present study evaluated the consequences of water restriction by Polyethylene glycol (PEG) and Sodium chloride (NaCl) on cell cycle and metabolism reactivation on germinability, seedling growth, and vigor parameters in 2 commercial castor genotypes (Nordestina and Paraguaçu).

The diagnosis of Chikungunya (CHIKV), along with the simultaneous monitoring of virus circulation in the population or vectors, is essential for global health. Although effective diagnostic methods for CHIKV, such as RT-qPCR, exist, their utilization is constrained by high costs. With the aim of contributing to the field of diagnostics, we have developed a diagnostic assay using isothermal amplification technology with visually interpretable results.

A new outbreak of hepatitis of unknown origin raised awareness in the international community. A few reports have attempted to associate new cases with adenovirus infection and the immunologic effects of previous SARS-CoV-2 infections through a superantigen mechanism. Moreover, according to a case series, viral isolates were identified in 7 of 10 cases of pediatric patients with hepatitis of unknown origin and acute liver failure.

Considering the high osteogenic potential of the bone morphogenetic protein 9 (BMP-9), we hypothesized that the secretome of MSCs overexpressing BMP-9 (MSCs ) enhances the osteoblast differentiation of MSCs and the bone formation in calvarial defects. CM of either MSCs (CM-MSCs ) or MSCs without BMP-9 overexpression (CM-MSCs ) were obtained at different periods.

The global demand for minimally processed vegetables (MPVs) has grown, driven by changes in the population's lifestyle. MPVs are fresh vegetables that undergo several processing steps, resulting in ready-to-eat products, providing convenience for consumers and food companies. Among the processing steps, washing-disinfection plays an important role in reducing the microbial load and eliminating pathogens that may be present.
