Diet and the Gut Microbiome as Determinants Modulating Metabolic Outcomes in Young Obese Adults.

Obesity, along with metabolic disorders such as dyslipidemia and insulin resistance, increases the risk of cardiovascular disease, diabetes, various cancers, and other non-communicable diseases, thereby contributing to higher mortality rates. The intestinal microbiome plays a crucial role in maintaining homeostasis and influencing human metabolism. This study enrolled 82 young obese individuals, who were stratified into groups with or without metabolic disturbances.

Effect of Lactobacillus reuteri NCIMB 30351 drops on symptoms of infantile functional gastrointestinal disorders and gut microbiota in early infants: Results from a randomized, placebo-controlled clinical trial.

Infantile functional gastrointestinal disorders, such as colic, constipation, diarrhea, and gastroesophageal reflux (regurgitation), often occur in early infancy and, representing one of the causes of significant parental anxiety, lead to a significant strain on the healthcare resources. In this study, we aimed to evaluate the effects of Lactobacillus reuteri drops (L. reuteri NCIMB 30351) on the symptoms of infantile colic, constipation, diarrhea, and gastroesophageal reflux, as well as on the levels of intestinal microbiota in full-term newborns during the first months of life.

Gut Microbiome in Post-COVID-19 Patients Is Linked to Immune and Cardiovascular Health Status but Not COVID-19 Severity.

The composition of the gut microbiome stores the imprints of prior infections and other impacts. COVID-19 can cause changes in inflammatory status that persist for a considerable time after infection ends. As the gut microbiome is closely associated with immunity and inflammation, the infection severity might be linked to its community structure dynamics.

Luminal and Tumor-Associated Gut Microbiome Features Linked to Precancerous Lesions Malignancy Risk: A Compositional Approach.

Colorectal cancer is the third most commonly diagnosed cancer worldwide. Human gut microbiome plays important roles in protecting against it, as well as contributing to its onset and progression. Identification of specific bacterial taxa associated with early stages of colorectal cancer may help develop effective microbiome-based diagnostics.

Detection of Y-chromosome marker in plasma of pregnant women using real time PCR: diagnostic accuracy depending on gestation age.

The evaluation of the clinical significance of the test for the detection of the Y-chromosome marker in the plasma of a pregnant woman at different stages of pregnancy by real-time PCR was carried out. The blood samples of 4616 women at 4 to 32 gestation weeks were studied. Identification of the Y-chromosome marker was carried out based on the amplification of a region of the TSPY gene.

Development of qPCR platform with probes for quantifying prevalent and biomedically relevant human gut microbial taxa.

Nowadays the advent of innovative high-throughput sequencing allows obtaining high-quality microbiome profiling. However, PCR-based tests are still considered the "golden standard" for many clinical applications. Here, we designed a qPCR-based platform with fluorescent-labeled oligonucleotide probes for assessing human gut microbiome composition.

Characterization of vaginal Lactobacillus species by rplK -based multiplex qPCR in Russian women.

We describe a multiplex qPCR assay for identification and quantitative assessment of a set of vaginal Lactobacillus species, including L. acidophilus, L. crispatus, L.

A novel real-time PCR assay for highly specific detection and quantification of vaginal lactobacilli.

PCR detection and quantification of vaginal lactobacilli remains problematic because of the high level of genetic heterogeneity and taxonomic complexity within the genus Lactobacillus. The aim of the present study was to identify conserved sequences among the genomes of major species of vaginal lactobacilli that could be used for the development of a PCR-based method for quantitative determination of vaginal microbiota-specific lactobacilli. Comparative analysis of the genomes of several species of vaginal lactobacilli allowed us to identify conserved regions in the rplK gene, which encodes ribosomal protein L11, and to design group-specific PCR primers and a probe for selected species from the L.
