Summary: This study found that cytokine levels were altered in patients with hepatic glycogen storage diseases (GSD), indicating an imbalance in the immunoregulation process. Moreover, neutrophils and some cytokines were affected by triglyceride levels. Future studies should consider this variable.

Summary: This study addressed the complex challenges associated with the application of inverse modeling in determining the hydraulic properties of layered soils with rock fragments (RF > 2 mm). Field drainage experiments were conducted in layered soil profiles with different particle size distributions and percentages of rock fragments to optimize the parameters of hydraulic functions. The bimodal van Genuchten-Mualem function provided a satisfactory fit of water contents and pressure heads measurements when both drainage and dew point potentiometer measurements were used simultaneously.

Summary: The Antarctic continent is experiencing rapid warming, which is impacting microbial communities in its ecosystems. Studying the effects of climate change on these communities is challenging, but novel experimental designs involving multiomics methods, continuous environmental data recording, and new warming simulation systems can help overcome these challenges. Additionally, research in Antarctica should prioritize descriptive studies, short-term temporary adaptation studies, and long-term adaptive evolution studies to gain a better understanding and management of climate change effects on Earth.

Summary: There is a lack of information about water retention in stony soils due to methodological difficulties. A new strategy was applied to measure water retention in soils with coarse fragments (CFs) and to examine the effect of CFs porosity on water retention. The results revealed that the water holding capacity of porous CFs in some soils is as high as the fine fraction. The water retention capacity in soils with porous CFs is underestimated when the internal porosity of the CFs is not considered.

Summary: The objective of this study was to assess the interaction effects of two magnesium (Mg) sources and a ruminal buffer on ruminal microbiota composition, fermentation, and nutrient digestibility in lactating dairy cows. The findings showed that calcium-magnesium hydroxide (CaMg(OH)(2)) improved ruminal fermentation and increased the concentration of butyrate and the abundance of butyrate-producing bacteria, regardless of buffer use. However, the use of a buffer improved the digestibility of dry matter, fiber, and other nutrients.

Summary: The role of gut microbiota in osteoporosis has gained attention in recent years. A meta-analysis of five 16S rRNA data sets revealed significant compositional and functional microbial alterations associated with osteoporosis. Opportunistic pathogens were increased, while short-chain fatty acid producers were depleted in the osteoporosis group. Lactic acid-producing bacteria were significantly increased. Functional prediction showed differences in SCFA and amino acid biosynthesis pathways. This study provides insight into the pathogenesis of osteoporosis and potential therapeutic interventions.

Summary: The long-term use and renewal of vineyards cause chemical changes in soil properties and microbial structure. This study evaluated the impact of vineyard renewal on the bioavailability of Cu and Zn and microbial diversity in southern Brazil. The results showed that vineyard renewal reduced Cu and Zn availability and increased microbial diversity in subtropical soils.

Summary: This study aimed to assess the impact of grazing management on a native grassland in southern Brazil. The findings indicate that increasing herbage allowance can lead to higher herbage mass and canopy height, while moderate grazing intensity maximizes intake rate.

Summary: Agaricus subrufescens, also known as the sun mushroom, has significant nutritional and medicinal value. The genome sequence of A. subrufescens provides valuable information for cultivation alternatives and genetic editing strategies to delay the browning process. The study also identified important genes and provided resources for further fungal biological and genomic studies.

Summary: Despite the availability of third-generation sequencing technologies, Illumina sequencing is still widely used in modern bacterial ecology studies for phylogenetic classification. Nanopore sequencing has now become a leading method for performing differential bacterial abundance analysis due to its ease, cost, and portability. A pipeline called RESCUE was developed to sequence bacterial rrn operons and improve taxonomic resolution, and it was shown to accurately classify species and resolve errors caused by short reads.

Summary: The objective of this study was to evaluate the effects of dietary supplementation of microencapsulated blend of organic acids and pure botanicals on the ruminal microbiome. The results showed that the supplement did not modulate the diversity and abundance of ruminal microbiome. The solid-associated microenvironment had a greater bacterial diversity and an increased abundance of carbohydrate-degrading microorganisms compared to the liquid-associated microenvironment.

Summary: In recent decades, agrochemicals have been linked to a decline in the global population of bees. Therefore, it is important to assess the toxicological effects of agrochemicals on stingless bees to understand the overall risks. This study examined the effects of commonly used agrochemicals (copper sulfate, glyphosate, and spinosad) on the behavior and gut microbiota of Partamona helleri stingless bees during the larval stage. The results showed that copper sulfate and spinosad, when used at recommended rates, reduced bee survival, while glyphosate had no significant effects. The agrochemicals also affected bee behavior, gut microbiota composition, and led to the accumulation of metals in the bees' bodies.

Summary: In this study, a new technique was used to sample undisturbed soil blocks coated with paraffin wax, preserving their structure. A saturated paste of fine-grained mineral particles was used to ensure hydraulic continuity. The technique successfully determined water retention curves for stony soils with coarse particles.

Summary: In recent decades, research on gut microbiome has grown significantly due to technological advances. Age, diet, and living environment are key factors influencing gut microbes and dysbiosis can impact bone health by altering bacterial metabolites. Restoring a healthy microbiome signature could reduce bone loss associated with osteoporosis or spaceflight. However, current research faces challenges such as contradictory findings and insufficient sample sizes.
