Halitosis is mainly caused by the action of oral microbes. The purpose of this study was to investigate the differences in salivary microbes and metabolites between subjects with and without halitosis. Of the 52 participants, 22 were classified into the halitosis group by the volatile sulfur compound analysis on breath samples. The 16S rRNA gene amplicon sequencing and metabolomics approaches were used to investigate the difference in microbes and metabolites in saliva of the control and halitosis groups. The profiles of microbiota and metabolites were relatively different between the halitosis and control groups. The relative abundances of Prevotella, Alloprevotella, and Megasphaera were significantly higher in the halitosis group. In contrast, the relative abundances of Streptococcus, Rothia, and Haemophilus were considerably higher in the control group. The levels of 5-aminovaleric acid and n-acetylornithine were significantly higher in the halitosis group. The correlation between identified metabolites and microbiota reveals that Alloprevotella and Prevotella might be related to the cadaverine and putrescine pathways that cause halitosis. This study could provide insight into the mechanisms of halitosis.

Obesity can be caused by microbes producing metabolites; it is thus important to determine the correlation between gut microbes and metabolites. This study aimed to identify gut microbiota-metabolomic signatures that change with a high-fat diet and understand the underlying mechanisms. To investigate the profiles of the gut microbiota and metabolites that changed after a 60% fat diet for 8 weeks, 16S rRNA gene amplicon sequencing and gas chromatography-mass spectrometry (GC-MS)-based metabolomic analyses were performed. Mice belonging to the HFD group showed a significant decrease in the relative abundance of Bacteroidetes but an increase in the relative abundance of Firmicutes compared to the control group. The relative abundance of Firmicutes, such as Lactococcus, Blautia, Lachnoclostridium, Oscillibacter, Ruminiclostridium, Harryflintia, Lactobacillus, Oscillospira, and Erysipelatoclostridium, was significantly higher in the HFD group than in the control group. The increased relative abundance of Firmicutes in the HFD group was positively correlated with fecal ribose, hypoxanthine, fructose, glycolic acid, ornithine, serum inositol, tyrosine, and glycine. Metabolic pathways affected by a high fat diet on serum were involved in aminoacyl-tRNA biosynthesis, glycine, serine and threonine metabolism, cysteine and methionine metabolism, glyoxylate and dicarboxylate metabolism, and phenylalanine, tyrosine, and trypto-phan biosynthesis. This study provides insight into the dysbiosis of gut microbiota and metabolites altered by HFD and may help to understand the mechanisms underlying obesity mediated by gut microbiota.

Objective: To explore the clinical effect of iRoot BP Plus pulpotomy for immediate repair in children with young permanent teeth crown fracture. Methods: From September 2017 to October 2018, 80 children (80 affected teeth) with young permanent teeth crown fracture who treated in the hospital were selected as the research objects. Random number table method was used to divide them into observation and control groups with each group of forty patients (40 affected teeth). The children in the control group were treated with calcium hydroxide resin, while the observation group were treated with iRoot BP Plus for immediate repair. The surgical success rate was compared between the two groups, and the pulp vitality before and after treatment were compared. Results: At 3 months and 6 months after surgery, the success rate of children in the observation group was higher than that in the control group, and the difference was statistically significant (P<0.05). The percentage of children with negative pulp activity in the observation group was higher than that in the control group, and the difference was statistically significant (P<0.05). Conclusion: Immediate repair with iRoot BP Plus pulpotomy in children with young permanent teeth crown fracture has significant clinical effect.

AbstractBackground and objectives:Chronic nonspecific pharyngitis is a chronic inflammation of the pharynx. It is found worldwide, and treatment is difficult. The underlying aetiopathogenesis is still controversial. The aim of this study was to investigate Helicobacter pylori seroprevalence in chronic nonspecific pharyngitis patients without other possible causative factors for chronic pharyngeal irritation and without H pylori gastric mucosal infection.Materials and methods:Forty-one patients with symptoms of chronic nonspecific pharyngitis and 30 healthy control subjects were enrolled in this prospective, controlled, clinical study. In both study and control groups, selected patients were shown to have gastric mucosa uninfected by H pylori, as demonstrated by the 14C-urea breath test. Comprehensive otorhinolaryngological examination did not elicit any factor contributing to the chronic pharyngeal complaint. Serum H pylori immunoglobulin G antibody titres were assayed using serum enzyme-linked immunosorbent assay. The difference between the study and control groups was analysed by the chi-square test (the likelihood ratio was used).Results:Thirty-two of the 41 patients (78 per cent) and 14 of the 30 control subjects (46.7 per cent) were found to be H pylori positive. Patients with chronic nonspecific pharyngitis were found to have a significantly higher rate of H pylori seropositivity than the control group (p = 0.016).Conclusion:These data may be important in developing future treatment strategies for chronic nonspecific pharyngitis.

Objectives: The aim of this study was to explore the cytomorphometric and morphological effects of Trichomonas vaginalis in exfoliated epithelial cells. Study Design: Ninety-six Pap-stained cervical smears were divided into a study group and two control groups as follows: T. vaginalis cases, a first control group with inflammation, and a second control group without inflammation. Micronucleated, binucleated, karyorrhectic, karyolytic, and karyopyknotic cells and cells with perinuclear halos per 1,000 epithelial cells were counted. Nuclear and cellular areas were evaluated in 70 clearly defined cells in each smear using image analysis. Results: The frequencies of morphological parameters in the T. vaginalis cases were higher than the values of the two control groups, and the difference among groups was found to be significant (p < 0.05). The nuclear and cytoplasmic areas of epithelial cells were diminished in patients with trichomoniasis. The mean nucleus/cytoplasm ratio in T. vaginalis patients was higher than the value in the control groups, and the difference between the study group and control group 1 was significant. However, there was no statistically significant increase between the study group and control group 2. Conclusions:T. vaginalis exhibited significant changes in the cellular size and nuclear structure of the cells. The rising frequency of micronuclei, nuclear abnormalities, and changing nucleus/cytoplasm ratio may reflect genotoxic damage in trichomoniasis.

Introduction: Palpable breast lumps are one of the most prevalent breast problems in women who visit a doctor. Most of these lumps are benign, and many of these benign lumps, have cystic nature. One of the suggested treatments for breast cyst is vitamin B6 intake. So, this study aimed to determine the effect of vitamin B6 on reducing the number and the size of breast cysts and reducing the amount of recurrence after aspiration. Materials and Methods: This study is a double-blind randomized clinical trial. Patients simply divided into two groups randomly, intervention group (receiving 150 mg vitamin B6 twice a day for two months) and control group (placebo). After data collection, the database produced, and information came in by SPSS-22 software. Descriptive results extracted in the form of tables and graphs. In all cases was used α=0.05. Results: At the end of the study, 65 patients (34 people in the intervention group, and 31 people in the control group) studied. At the end of the survey in the non-palpable cysts, was observed a significant decrease in the number and the size of breast cysts in each group receiving vitamin B6 or placebo. Still, the difference was not significant in comparing the two groups. 19 patients (2.29%) had palpable cysts that aspiration performed in all cases. After the study period, no recurrence of cysts observed in any of the intervention and control groups. Conclusion: The study showed that vitamin B6 had no effect on reducing the size and the number of non-palpable breast cysts and prevent recurrence of palpable cysts after aspiration.

Breast milk from a single mother was collected during a 28-week lactation period. Bacterial diversity was studied by amplicon sequencing analysis of the V3-V4 variable region of the 16S rRNA gene. Firmicutes and Proteobacteria were the main phyla detected in the milk samples, followed by Actinobacteria and Bacteroidetes. The proportion of Firmicutes to Proteobacteria changed considerably depending on the sampling week. A total of 411 genera or higher taxons were detected in the set of samples. Genus Streptococcus was detected during the 28-week sampling period, at relative abundances between 2.0% and 68.8%, and it was the most abundant group in 14 of the samples. Carnobacterium and Lactobacillus had low relative abundances. At the genus level, bacterial diversity changed considerably at certain weeks within the studied period. The weeks or periods with lowest relative abundance of Streptococcus had more diverse bacterial compositions including genera belonging to Proteobacteria that were poorly represented in the rest of the samples.

(Background) Left ventricular (LV) untwisting behavior is a novel index of LV diastolic function since it is a powerful determinant of LV diastolic suction. The LV of patients with hypertrophic cardiomyopathy (HCM) and hypertensive heart disease (HHD) has diastolic dysfunction despite normal systolic function. However, the role of untwisting behavior in HCM and HHD in the pathophysiology of diastolic dysfunction is unknown. The aim of this study was to investigate the difference of LV twisting behavior between patients with HCM and HHD. (Methods) Forty-four patients with HCM (mean age, 63+/−15 y, 34 males), 30 patients with HHD (mean age, 62+/−12 y, 20 males), and 20 age and sex-matched control subjects were evaluated. After a standard echocardiographic examination, LV twist and twisting velocity profiles from apical and basal short-axis images were analyzed using two-dimensional speckle tracking imaging. All temporal parameters were normalized by R-R intervals. (Results) LV diastolic and systolic dimensions, and ejection fraction were not significantly different among the groups. LV mass index and early diastolic mitral annular velocity were not significantly different between the HCM and HHD groups. The peak torsion in the HCM and HHD groups was significantly greater than that in the control group (Table ). The peak untwisting velocity in the HCM group was comparable to that in the control group. However, when the peak untwisting velocity was corrected by peak torsion, the value in the HCM group was significantly decreased compared with that in the HHD and control groups. The time to peak untwisting velocity from aortic valve closure in the HCM group was significantly longer than that in the HHD and control groups. (Conclusion) These results suggest that enhanced peak torsion in HCM might compensate for untwisting behavior, but this mechanism fails to fully compensate for untwisting behavior compared with HHD.
