Summary: This study evaluates microbial alterations in breast cancer patients compared to control subjects and explores intestinal microbial modifications from various breast cancer treatments. The results show an increase in gut and breast bacterial species in breast tumor cases, specifically a significant increase in Methylobacterium radiotolerans compared to healthy breast tissue. Additionally, patients with breast cancer have lower intestinal microbial diversity. Qualitative analysis identifies microbial abundance patterns in different sample types, detection methods, menopausal status, nationality, obesity, sleep quality, and various interventions.

Summary: This study investigated the effects of interactions between microfibers and freshwater acidification (MFA) on individual Daphnia magna-microbiota interactions. The results showed that MFA interactions can have negative consequences on reproduction, growth, and sex ratio of D. magna, and can induce changes in immunity-and reproduction-related biological processes. The study also revealed that these adverse effects are closely related to changes in microbial communities, suggesting a causal link between D. magna fitness and the microbial community.

Summary: This study aimed to review the association between gut microbiome and pain in OA patients and found only three out of 2084 studies supported a relationship, but the results were not conclusive. It also highlighted the lack of high-quality studies and significant technique disparities, making it impossible to draw firm conclusions on the topic.

Summary: This study investigated the fecal microbial composition of chronic spontaneous urticaria (CSU) patients, revealing the presence of gut microbiota dysbiosis. The dominant microbiota in CSU patients included Proteobacteria, Bacilli, Enterobacterales, and Enterobacteriaceae, with decreased levels of Megamonas, Megasphaera, and Dialister compared to healthy controls. Functional prediction indicated abnormal pathways in CSU patients, suggesting a potential link between gut microbiota dysbiosis and the pathogenesis of CSU.

Summary: This prospective longitudinal study revealed distinct differences in gut microbiome between pediatric patients with functional abdominal pain disorders (FAPDs) and healthy controls, with variations observed not only in bacterial populations but also in diversity levels. The severity of symptoms in patients was found to be correlated with the gut microbiome, highlighting a potential relationship between the two. Additionally, the Faecalibacterium/Bacteroides ratio may serve as a promising diagnostic biomarker for FAPDs.

Summary: The human gut contains trillions of microbes that play a crucial role in various health functions, but they are also associated with numerous diseases. Microbiome transplants offer a potential solution to mitigate these health issues caused by the gut microbiome. This article provides an overview of the gut's functional relationships, highlights the diseases directly affected, and explores the history and applications of microbiome transplants in various diseases.

Summary: Maternal influences on the immune health and development of an infant begin in utero and continue after birth, shaping and educating the child's immune system. Two important provisions from the mother include early microbial colonizers and the transfer of antibodies. These provisions help educate the developing neonatal immune system, connecting with the microbiota and influencing disease development.

Summary: This study found that shrimp can obtain additional LC-PUFA from the pond's primary production in semi-intensive shrimp ponds, rather than solely relying on feed. Achieving a balance between LC-PUFA contribution through formulated feed and natural production can lead to sustainable shrimp farming.

Summary: Hybridization between species in the Brachionus calyciflorus complex was observed, leading to lower viability and higher mortality in hybrid dormant propagules. Most hybrid clones showed a low incidence of sexual reproduction, which may reduce their long-term fitness. Postzygotic barriers, such as high mortality of dormant propagules and low sexual reproduction ability in hybrids, likely impede genetic exchange between parental species and help maintain their integrity.

Summary: The study showed that population growth rates of rotifers were consistently higher on algae with excess or intermediate phosphorus content grown in chemostats compared to those treated with phosphorus supplementation. Additionally, growth rates were consistently lower in high phosphorus treatments than in medium phosphorus treatments, suggesting the existence of a stoichiometric knife-edge. This confirms that phosphorus supplementation is a reliable method for studying the relative effect of excess phosphorus on zooplankton performance in a standardized way.

Summary: This study tested for prezygotic barriers between two closely related species in Brachionus calyciflorus. The results demonstrated a strong prezygotic reproductive barrier that plays a role in maintaining species boundaries. However, the presence of hybrids also suggests the potential for gene flow between the species through hybridization.

Summary: Functional trade-offs play a key role in determining the diversity of communities and the changes in species composition along environmental gradients. A trade-off between predator defense and resource competitive ability could maintain diversity in lake phytoplankton. Trade-offs may promote diversity in communities where grazing- and resource-limited taxa coexist, which affects whether communities are more resource- or consumer-controlled.

Summary: The growth rate hypothesis (GRH) suggests that the relative phosphorus content of an organism is positively related to somatic growth rate. In a phosphorus-rich environment, evolution towards higher growth rate is accompanied by an increase in relative phosphorus content, while in a phosphorus-poor environment, the increase in growth rate does not lead to an increase in relative phosphorus content.

Summary: Submerged macrophytes promote water clarity in high-altitude Andean shallow lakes by reducing the cyanobacteria bloom and increasing zooplankton grazing. In a series of experiments in Yahuarcocha Lake, it was found that the presence of Egeria densa resulted in a strong reduction in cyanobacteria, while the small-sized fish Poecilia reticulata promoted cyanobacteria dominance. The combination of E. densa, fish, and zooplankton substantially reduced the algae, indicating the important role of submerged plants in improving water quality in high-elevation eutrophic ecosystems.

Summary: The depletion of oxygen due to increased stratification and decreased solubility is a significant chemical change in aquatic ecosystems under global environmental change, leading to increased exposure of aquatic organisms to hypoxic conditions. Understanding the effects of hypoxia on key ecological species and their microbial communities is crucial for predicting the response of aquatic communities to this environmental disturbance. In this study, the (sub-)lethal effects of hypoxia on Daphnia, a keystone species in freshwater ecosystems, were examined, along with the potential role of the microbial community in the phenotypic switch and tolerance to hypoxia. The results showed phenotypic plasticity in Daphnia performance traits, as well as changes in species richness and community composition of the microbial community, suggesting the importance of the microbiome in phenotypic plasticity and hypoxia tolerance in Daphnia.
