Members of the genus and lactobacilli are the most commonly used probiotics to promote human health. In this context, genome-based analyses have been demonstrated as a fast and reliable tool for identifying and characterizing health-promoting activities imputed to probiotics. This study is an extension of the Integrated Probiotic Database (IPDB) previously created on probiotics of the genus , facilitating a comprehensive understanding of the genetic characteristics that contribute to the diverse spectrum of beneficial effects of probiotics.

Bifidobacteria are well known as common and abundant colonizers of the human gut and are able to exert multiple beneficial effects on their host, although the cooperative and competitive relationships that may occur among bifidobacterial strains are still poorly investigated. Therefore, to dissect possible molecular interactions among bifidobacterial species that typically colonize the human gut, three previously identified bifidobacterial prototypes, i.e.

Accordingly, vitamin production by intestinal commensals has attracted significant interest. Nevertheless, our current understanding of bacterial vitamin synthesis is primarily based on individual genomic and monoculture investigations, therefore not providing an overall view of the biosynthetic potential of complex microbial communities.

In this study, ten different artificial gut microbiota (AGM), obtained by culturing fecal samples in a continuous fermentation system, were challenged for their metabolizing capacity on a panel of six glucocorticoids selected from either prodrugs or drugs. Data from metabolic stability assays highlighted that, while the hydrolysis-mediated conversion of prodrugs to drugs represented only a minor metabolic pathway, significant differences in the stability of parent compounds and in their conversion rates to multiple reductive metabolites were obtained for the selected drugs.

Data And Methods: This retrospective cohort study was conducted using health administrative data from ICES (formerly known as the Institute for Clinical Evaluative Sciences).
Objectives: Long-term care (LTC) homes provide personal and medical care 24/7 to individuals unable to live at home due to illness or disability and are often the final place of care and death for their residents. Therefore, LTC homes are tasked with providing quality end-of-life care, often requiring injectable symptom management medications to relieve distressing symptoms (eg, pain). In this study, we aimed to understand the enablers and barriers to prescribing and administering end-of-life symptom management medications in LTC homes.

Nevertheless, the canine oral ecosystem and its correlations with oral disease development are still far from being fully characterized. In this study, the species-level taxonomic composition of saliva and dental plaque microbiota of 30 healthy dogs was investigated through a shallow shotgun metagenomics approach.

The speed and extent of such decline are dependent on lifestyle, environment, and genetic factors. Moreover, with advancing age, humans become progressively more fragile and prone to acute and chronic diseases.

Current study investigated the longitudinal changes in Bifidobacterium population during the first two years of life in 196 term born infants (1,654 samples) using 16S rRNA-23S rRNA internal transcribed spacer (ITS) sequence analysis. Throughout the first two years of life, Bifidobacterium breve, Bifidobacterium longum subsp.

However, significant gaps remain in our understanding of the genomic characteristics of this emerging microbial group. In this study, we utilized all available high-quality genomes of Hafnia alvei and Hafnia paralvei to uncover the broad distribution of Hafnia in human and honeybee guts, as well as in dairy products, by analysing 1068 metagenomic datasets.

The NPs' surface coating impacts the way they translocate through the lipid bilayer and the spontaneity of the process. Understanding the molecular details of NPs' interaction with cell membranes allows the design of nanosystems with optimal characteristics for crossing the lipid bilayer: computer simulations are a powerful tool for this purpose.

The gut microbiota undergoes dramatic developmental changes during the first year of life, being influenced by a variety of external factors, with diet being a major player. Indeed, the introduction of complementary feeding provides novel nutritive substrates and triggers a shift from milk-adapted gut microbiota toward an adult-like bacterial composition, which is characterized by an enhancement in diversity and proportions of fiber-degrading bacterial genera like Ruminococcus, Prevotella, Eubacterium, and Bacteroides genera.

Chemotherapy in combination with immunotherapy can restrict tumor progression and repolarize the tumor microenvironment towards an anti-tumor milieu, improving clinical outcome in TNBC patients. The chemotherapeutic drug paclitaxel has been shown to induce immunogenic cell death (ICD), whereas inhibitors of the indoleamine 2,3- dioxygenase 1 (IDO1) enzyme, whose expression is shared in immune regulatory and tumor cells, have been revealed to enhance the anti-tumor immune response.

However, these developments are often hampered by the presence of a large amount of human DNA interfering with the analysis of the bacterial content. Nowadays, extensive scientific literature focuses on eukaryotic DNA depletion methods, which successfully remove host DNA in microbiome studies, even if a precise assessment of the impact on bacterial DNA is often missing.

Yet, little is known about the symptom management long-term care (LTC) residents receive at the end of life. Our research team developed a metric-whether residents receive one or more prescriptions for an end-of-life symptom management medication in their last two weeks-to explore end-of-life care for LTC residents.
