Trophic Niche Differentiation in Two Sympatric Nuthatch Species ( and ).

Sympatric closely related species may experience interspecific trophic competition due to ecological similarity; they may isolate in terms of diet or habitat use as a strategy to avoid competition. The body tissues of consumers contain stable isotope signatures information that can be applied to infer their dietary information. In this study, δC and δN stable isotopes were analyzed to determine the dietary information and trophic niches of sympatric coexisting and .

Evaluation of the biological effect of mineral trioxide aggregate in inflamed pulp- analysis.

The health of dental pulp tissue is critical to maintaining normal tooth function from the eruption of permanent teeth to the formation of the apex. The study evaluated the inflamed pulp response to the mineral trioxide aggregate (MTA) after direct pulp capping with the mechanical pulp exposure in rats' incisor. Forty-eight mandibular central incisors of twenty-four Sprague-Dawley rats which were prepared with the cavities of one mm diameter, and the pulp exposures were randomly assigned into two groups: MTA group and calcium hydroxide (Ca(OH)) group.

Nest-Site Features and Breeding Ecology of Chestnut-Vented Nuthatch in Southwestern China.

The breeding ecology of birds is the cornerstone of bird life-history theory, and breeding success directly affects the survival and development of populations. We studied the breeding ecology of a secondary cavity-nesting bird, the chestnut-vented nuthatch , in southwestern China from March to June in 2020, 2021, and 2022. In total, 16 nests in nest boxes and 19 nests in natural cavities were studied.

Oral microbiome characteristics in children with and without early childhood caries.

Objective: Early childhood caries (ECC) negatively affects children's growth due to its close relation to an imbalance of the oral microbiota. This study aimed to evaluate the distribution of the oral microbiota in children with ECC and healthy individuals.

Methods: The oral microbiota of 20 children with dental caries from both carious teeth (CC cohort) and healthy teeth (CH cohort), and the oral microbiota of 20 healthy control children (HH cohort) were subjected to 16S rDNA sequencing.

Evaluation of heat-inactivated CCFM1139 and its supernatant for the relief of experimental periodontitis in rats.

Periodontitis is a chronic inflammatory disease induced by subgingival microbial dysbiosis, characterised by inflammation of the soft tissues of the periodontium and progressive loss of alveolar bone. CCFM1139 is a probiotic with the potential to relieve periodontitis and . Due to the cost of active strain in production applications, we considered the effectiveness of bacterial components and metabolites in alleviating experimental periodontitis.

CCFM8724 Reduces the Amounts of Oral Pathogens and Alters the Oral Microbiota in Children With Dental Caries: a Randomized, Double-Blind, Placebo-Controlled Trial.

Early childhood caries (ECC) is closely related to the disorders of oral microbiota. Probiotics antagonize pathogenic bacteria and regulate the composition of the microbiota. We aimed to investigate the effects of CCFM8724 on , , and oral microbiota of patients.

Effects of Limosilactobacillus fermentum CCFM1139 on experimental periodontitis in rats.

Periodontitis is a polymicrobial inflammatory disease often characterized by the excessive colonization of Porphyromonas gingivalis and Fusobacterium nucleatum, which causes alveolar bone resorption and advanced oral inflammation. This study aimed to evaluate the effect of Limosilactobacillus fermentum CCFM1139 on experimental periodontitis induced following ligature and infection with P. gingivalis and F.

[Relationships among tongue volume, hyoid position, airway volume and maxillofacial form in paediatric patients with Class Ⅰ, Class Ⅱ and Class Ⅲ malocclusions].

Purpose: To investigate the relationships among tongue volume, hyoid position, airway volume and maxillofacial form in paediatric patients with Class Ⅰ, Class Ⅱ and Class Ⅲ malocclusion.

Methods: Data of 112 children with malocclusion in the Department of Stomatology, Wuxi Children's Hospital from December 2015 to December 2018 were collected. The children were divided into three groups according to Angle's classification: Class Ⅰ (n=42), Class Ⅱ (n=38) and Class Ⅲ (n=32).

Inhibitory Effect of CCFM8724 towards - and -Induced Caries in Rats.

is a recognized cariogenic bacterium and a major producer of biofilm matrix. The presence of in dental plaque with . enhances the virulence leading to the onset of rampant caries which is similar to early childhood caries (ECC).

Inhibitory and preventive effects of FB-T9 on dental caries in rats.

is recognized as the main cause of dental caries, and the formation of a plaque biofilm is required for caries development. This study aimed to determine the inhibitory effect of FB-T9 on biofilm formation and on the prevention and treatment of dental caries in rats. During experiments, FB-T9 exhibited good bacteriostatic ability in a plate competition assay.

[Serum levels of sVCAM-1, IL-18 and VEGF in patients with aplastic anemia and their clinical significance].

This study was purposed to investigate the serum levels of soluble intracellular adhesion molecule (sVCAM-1), interleukin 18 (IL-18) and vascular endothelial growth factor (VEGF) in patients with aplastic anemia (AA) and their clinical significance. Enzyme linked immunosorbent assay (ELISA) was used to detect sVCAM-1, IL-18 and VEGF in serums of 30 patients with AA and 25 normal controls. The results showed that the serum levels of sVCAM-1 and IL-18 in patients with AA [(839.
