Central retinal vein occlusion after infliximab therapy in a young patient with ulcerative colitis.

Inflammatory bowel disease (IBD) is a chronic condition, characterized by recurrent inflammation of the gastrointestinal tract. While the primary focus of IBD management consists in controlling gastrointestinal symptoms, IBD also presents an increased risk of thromboembolic complications. Tumor necrosis factor alpha (TNF-α) inhibitors, namely infliximab, have become increasingly common in the management of multiple chronic inflammatory diseases such as IBD.

Association of Moderate and Vigorous Physical Activity With Cognitive Performance: Evidence From Brazil.

Objective: It is estimated that 2% of dementia cases worldwide could be prevented with increases in physical activity. However, there is little evidence of the association between vigorous physical activity (VPA) and cognitive performance. This study aimed to investigate the association of moderate physical activity (MPA) and VPA with cognitive performance in older adults from the Brazilian Longitudinal Study of Aging (ELSI-Brasil).

Foliar Spraying with ZnSO or ZnO of cv. Syrah Increases the Synthesis of Photoassimilates and Favors Winemaking.

Zinc enrichment of edible food products, through the soil and/or foliar application of fertilizers, is a strategy that can increase the contents of some nutrients, namely Zn. In this context, a workflow for agronomic enrichment with zinc was carried out on irrigated cv. Syrah, aiming to evaluate the mobilization of photoassimilates to the winegrapes and the consequences of this for winemaking.

Uncovering the wide protective responses in spp. leaves to single and superimposed exposure of warming and severe water deficit.

Climate changes boosted the frequency and severity of drought and heat events, with aggravated when these stresses occur simultaneously, turning crucial to unveil the plant response mechanisms to such harsh conditions. Therefore, plant responses/resilience to single and combined exposure to severe water deficit (SWD) and heat were assessed in two cultivars of the main coffee-producing species: cv. Icatu and cv.

Fast enterocyte regrowth after infection involves a reverse metabolic flux driven by an amino acid transporter.

Upon exposure to a bacterial pore-forming toxin, enterocytes rapidly purge their apical cytoplasm into the gut lumen, resulting in a thin intestinal epithelium. The enterocytes regain their original shape and thickness within 16 h after the ingestion of the bacteria. Here, we show that the regrowth of enterocytes entails an inversion of metabolic fluxes from the organism back toward the intestine.

Assessment of Physicochemical Parameters in Two Winegrapes Varieties after Foliar Application of ZnSO and ZnO.

One-third of the world's population is suffering from "hidden hunger" due to micronutrient deficiency. Zinc is acquired through diet, leading its deficiency to the development of disorders such as retarded growth, anorexia, infections, and hypogeusia. Accordingly, this study aimed to develop an agronomic workflow for Zn biofortification on two red winegrapes varieties (cv.

Wheat Crop under Waterlogging: Potential Soil and Plant Effects.

Inundation, excessive precipitation, or inadequate field drainage can cause waterlogging of cultivated land. It is anticipated that climate change will increase the frequency, intensity, and unpredictability of flooding events. This stress affects 10-15 million hectares of wheat every year, resulting in 20-50% yield losses.

Magnesium Accumulation in Two Contrasting Varieties of L. Fruits: Interaction with Calcium at Tissue Level and Implications on Quality.

As the productivity and quality of tomato fruits are responsive to Mg applications, without surpassing the threshold of toxicity, the assessment of potential levels of Mg accumulation in tissues, as well as the interactions with Ca and physicochemical properties, prompt this study. An agronomic workflow for Mg enrichment, consisting of six foliar applications of MgSO with four concentrations (0%, 0.25%, 1% and 4%), equivalent to 0, 43.

Foliar Spraying of L. with CaCl and Ca(NO): Interactions with Nutrients Accumulation in Tubers.

Calcium is essential for plants, yet as its mobility is limited, the understanding of the rate of Ca accumulation and deposition in tissues of tubers, as well as the interactions with other critical nutrients prompted this study. To assess the interactions and differential accumulation of micro and macronutrients in the tissues of tubers, L. varieties Agria and Rossi were cultivated and, after the beginning of tuberization, four foliar sprayings (at 8-10 day intervals) with CaCl (3 and 6 kg ha) or Ca(NO) (2 and 4 kg ha) solutions were performed.

Grain Composition and Quality in Portuguese Germplasm Subjected to Heat Stress after Anthesis.

Bread wheat () is a major crop worldwide, and it is highly susceptible to heat. In this work, grain production and composition were evaluated in Portuguese germplasm (landraces and commercial varieties), which was subjected to heat after anthesis (grain filling stage). Heat increased the test weight (TW) in Nabão, Grécia and Restauração, indicating an improved flour-yield potential.

Will Stress Resilience Be Maintained in the Face of Climate Change?

Actinorhizal plants have been regarded as promising species in the current climate change context due to their high tolerance to a multitude of abiotic stresses. While combined salt-heat stress effects have been studied in crop species, their impact on the model actinorhizal plant, , has not yet been fully addressed. The effect of single salt (400 mM NaCl) and heat (control at 26/22 °C, supra optimal temperatures at 35/22 °C and 45/22 °C day/night) conditions on branchlets was characterised at the physiological level, and stress-induced metabolite changes were characterised by mass spectrometry-based metabolomics.

Implications of nighttime temperature on metamitron impacts on the photosynthetic machinery functioning of Malus x domestica Borkh.

Metamitron (MET) is a fruitlet thinning compound for apple trees, needing better understanding of its action on leaf energy metabolism, depending on nighttime temperature. A trial under environmental controlled conditions was set with 'Golden Reinders' potted trees, under 25/7.5 and 25/15 °C (diurnal/nighttime temperature), with (MET, 247.

Effect of Rice Grain ( L.) Enrichment with Selenium on Foliar Leaf Gas Exchanges and Accumulation of Nutrients.

An agronomic itinerary for Se biofortification of two rice cultivars (Ariete and Ceres) through foliar fertilization with sodium selenate and sodium selenite with different concentrations (25, 50, 75 and 100 g Se.ha), was implemented in experimental fields. The selenium toxicity threshold was not exceeded, as shown by the eco-physiological data obtained through leaf gas exchanges.

Can Foliar Pulverization with CaCl and Ca(NO) Trigger Ca Enrichment in L. Tubers?

This study aimed to assess the efficiency of Ca enrichment in tubers of three genotypes of L., through foliar spraying with CaCl and Ca(NO) solutions. In this context, soil heterogeneity of three potato-growing fields, as well as the implications of Ca accumulation among tissues and some quality parameters were assessed.

Zinc Enrichment in two Contrasting Genotypes of L. Grains: Interactions between Edaphic Conditions and Foliar Fertilizers.

This study aimed to assess the implications of Zn enrichment in wheat grains as a function of contrasting genotypes, edaphic conditions and foliar fertilizers. L. varieties Roxo and Paiva were grown in four production fields, and sprayed with ZnSO (0, 16.
