The objectives of this study were to assess the ideal volume of Copan FecalSwab™ (FS) preserved stool sample to use with the BD MAX™ Enteric Bacterial Panel and the Extended Enteric Bacterial Panel (BDM GIP) and to compare the performance of FS to the recommended Meridian Para-Pak Cary-Blair medium (PP) for the BDM GIP. Three different input volumes (10, 25, and 50 μL) of stool inoculated with American Type Culture Collection strains representing the targets detected by BDM GIP were tested. Additionally, 144 unpreserved stool samples submitted for gastrointestinal (GI) testing were transferred to PP and FS media and tested by the BDM GIP using 10 μL of PP and 50 μL of FS media. A 100% agreement was observed between PP and FS results. The performance of 50 μL of FS stool preserved sample was equivalent to 10 μL of traditional Cary-Blair PP preserved specimens for GI pathogens detection using the BDM GIP.Objective Some recent studies suggest that maternal prenatal stress (MPS) increases allergic diseases in the children. However, knowledge on this issue in Asian children are lacking. We investigated the association between MPS and the risks of wheeze and asthma in Japanese infants aged 16-24 months. Methods The present subjects were 763 Japanese mother-child pairs. The first, second, and third surveys based on self-administered questionnaires were performed during pregnancy, between 2 and 9 months postpartum, and from 16 to 24 months postpartum, respectively. Data on MPS was obtained in the first survey, using the Stress Inventory (SI), which constructs 12 specific behavioral patterns as response styles to stressors. Data on wheeze and asthma was obtained in the third survey, where wheeze was based on the International Study of Asthma and Allergies in Childhood criteria and asthma was based on doctors' diagnosis. Results There were 169 infants with wheeze (22.1%) and 33 infants with asthma (4.3%), at the time of the third survey. Multiple logistic regression analyses found that a maternal behavioral pattern characterized by chronic irritation and anger was associated with the risk of childhood asthma (adjusted odds ratio [OR] = 1.56, 95% confidence interval [CI] 1.11 to 2.22), but not wheeze (adjusted OR = 1.02, 95%CI 0.88 to 1.19), while there was no appreciable association between the other SI scales and the risk of childhood wheeze or asthma. Conclusions The results partly supported the hypothesis that MPS might increase the risk of asthma in their infants in Japanese.COVID-19 virus is primarily transmitted between humans through respiratory droplets and contact routes.•Transportation of COVID-19 patient carries very high transmission risk to personals involved.•Worldwide, clinicians are using many measures that can be executed easily to prevent aerosol exposure.Cholinergic agonists, like levamisole, are a major class of anthelmintic drugs that are known to act selectively on nicotinic acetylcholine receptors (nAChRs) on the somatic muscle and nerves of nematode parasites to produce their contraction and spastic paralysis. Previous studies have suggested that in addition to the nAChRs found on muscle and nerves, there are nAChRs on non-excitable tissues of nematode parasites. We looked for evidence of nAChRs expression in the cells of the intestine of the large pig nematode, Ascaris suum, using RT-PCR and RNAscope in situ hybridization and detected mRNA of nAChR subunits in the cells. These subunits include components of the putative levamisole receptor in A. selleck compound suum muscle Asu-unc-38, Asu-unc-29, Asu-unc-63 and Asu-acr-8. link2 Relative expression of these mRNAs in A. suum intestine was quantified by qPCR. We also looked for and found expression of G protein-linked acetylcholine receptors (Asu-gar-1). We used Fluo-3 AM to detect intracellular calcium changes in response to receptor activation by acetylcholine (as a non-selective agonist) and levamisole (as an L-type nAChR agonist) to look for evidence of functioning nAChRs in the intestine. We found that both acetylcholine and levamisole elicited increases in intracellular calcium but their signal profiles in isolated intestinal tissues were different, suggesting activation of different receptor sets. The levamisole responses were blocked by mecamylamine, a nicotinic receptor antagonist in A. suum, indicating the activation of intestinal nAChRs rather than G protein-linked acetylcholine receptors (GARs) by levamisole. The detection of nAChRs in cells of the intestine, in addition to those on muscles and nerves, reveals another site of action of the cholinergic anthelmintics and a site that may contribute to the synergistic interactions of cholinergic anthelmintics with other anthelmintics that affect the intestine (Cry5B).Background Thyroid Imaging Reporting Data System (TI-RADS) is used to characterize thyroid nodules while reducing unnecessary FNAC. Over the years, several versions of TI-RADS have been developed but there is no consensus on which TI-RADS is the best system. This study aimed to compare the diagnostic accuracy and ability of ACR TI-RADS, EU TI-RADS, K TI-RADS, AI TI-RADS to eliminate unnecessary FNAC. Methods In this prospective study, thyroid nodules were characterized by using the four TI-RADS systems and US-guided FNAC was done for nodule with the highest ACR TI-RADS score. Correlation between TI-RADS and FNAC results were analyzed. Results Out of 244 thyroid nodules, 100 nodules with either size less then 1 cm (43 nodules) non-diagnostic or inconclusive FNAC results (57 nodules) were excluded. Seven nodules (4.9%) were confirmed to be malignant on FNAC. K TI-RADS showed 100% sensitivity and NPV but the lowest specificity (40.2%). EU TI-RADS had the highest specificity (83.2%) but the lowest sensitivity (57.1%) and NPV (97.4%). ACR TI-RADS had an average sensitivity (85.7%) and NPV (98.6%). The specificity of ACR TI-RADS (51.1%) was lower than EU TI-RADS but higher than K TI-RADS. AI TI-RADS showed higher specificity (61.8% vs 51.1%, p less then 0.05) but comparable NPV and sensitivity to ACR TI-RADS. AI TI-RADS was able to avoid the highest number of unnecessary FNAC (62.5%) followed by ACR TI-RADS(54.2%), EU TI-RADS(37.5%) and K TI-RADS(11.8%). Conclusion AI TI-RADS is a more simple scoring system with better overall diagnostic performance and ability to exclude unnecessary FNAC with high NPV. Advances in knowledge Highest number of unnecessary FNAC thyroid could be prevented by applying AI TI-RADS.Objective Baicalin mediates bone metabolism and has shown protective activity against periodontal tissue damage in a rat model of periodontitis. Therefore, we hypothesized that baicalin may inhibit the root resorption that occurs during orthodontic tooth movement and examined its effect on the histological changes in periodontal tissue that occur during tooth movement. Methods First molars of rats were subjected to traction using excessive orthodontic force to produce a root resorption model. Rats in the baicalin group received baicalin for 3 weeks during tooth movement, and the amount of first molar movement on day 21 after the initiation of traction was measured by three-dimensional micro-computed tomography analysis. After tooth movement, tissue samples from the mesial and tension sides were collected, and successive horizontal sections were prepared and examined using hematoxylin-eosin and tartrate-resistant acid phosphatase (TRAP) staining and immunohistochemical staining for the receptor activator of NF-kB ligand (RANKL) and osteoprotegerin (OPG). The severity of root resorption was also determined by histological analysis. Results There was no significant intergroup difference in tooth movement during the experimental exaggerated tooth movement. In comparison with the control group, the baicalin-treated group showed increased OPG expression, suppressed RANKL expression, and significantly fewer TRAP-positive cells in the first molars. The root resorption area was significantly smaller in the baicalin group. Conclusions Treatment with baicalin prevented root resorption without preventing tooth movement. Baicalin may be useful for the management of root resorption during orthodontic treatment.Objective Diabetes increases the incidence/severity of periodontal diseases by inducing a chronic inflammation, driven by accumulation of AGEs (advanced glycation end products). We tested whether glycated human serum albumin (G-HSA, a form of AGE), representing a diabetic state, augments the pro-inflammatory response of human gingival fibroblasts (hGFs) to a bacterial challenge (Porphyromonas gingivalis Lipopolysaccharide (LPS)). Methods Primary hGFs were incubated with LPS (0.5-5 μg/mL) and G-HSA (50-200 μg/mL) and the production and gene expression of IL-1β, IL-6, IL-8, MMP-1, MCP-1, and TNFα were analyzed by Magnetic Luminex Assay and real-time PCR, respectively. Non-glycated serum albumin (HSA) served as negative control. Cytotoxicity of the 2 agents was tested with an XTT assay. NFκB activation (p65 phosphorylation) was measured with an ELISA. Results P. gingivalis LPS and G-HSA were not toxic to hGFs and increased the amount of MMP-1, MCP-1, IL-6, and IL-8, (but not TNFα and IL-1β) secreted into the medium at 24 h. Control HSA had no effect. Many LPS/G-HSA combinations displayed a synergistic stimulation of these molecules. Both agents increased mRNA levels of these 4 molecules at 6 h, 12 h or both (IL-6). NFκB activation at 6 h was caused by both agents with a possible synergism at the higher concentrations. Conclusions glycated albumin augments the pro-inflammatory response of human gingival fibroblasts to P. gingivalis LPS. Thus, AGE accumulation in diabetes could aggravate periodontal inflammation by augmenting the pro-inflammatory response of host GFs to P. gingivalis, a well-recognized periopathogenic bacteria.Objective We examined the effects of vitamin C and E supplementation in the prevention of oxidative stress in the salivary glands of STZ-induced diabetic rats. Design Forty-eight male Wistar rats were divided into six groups (n = 8 in each) control (C), control supplemented with vitamin C (Cvc) and E (Cve), diabetic (D), and diabetic supplemented with vitamin C (Dvc) and E (Dve). Vitamin C (150 mg/kg) and E (300 mg/kg) were daily administered for 21 days. Serum ascorbic acid and α-tocopherol levels were quantified. Glandular levels of hydrogen peroxide (H2O2), superoxide anion (O2-), superoxide dismutase (SOD), glutathione peroxidase (GPx), glutathione reductase (GR), catalase (CAT), malondialdehyde (MDA) and the total antioxidant status (TAS) were estimated. Results Vitamin C and E levels were reduced in D group. Vitamin C decreased the levels of O2- in the salivary gland of diabetic rats. Vitamin E increased the concentration of O2- in PA gland of diabetic animals. In the SM gland of the diabetic group, MDA, SOD, GPx and TAS increased. Dve presented reduced SOD activity and increased GR, GPx, and MDA. Dve increased GPx, Gr and TAS levels. In the PA gland, MDA, SOD, CAT, GPx, GR, and TAS were similar in C and D. TAS, SOD, CAT, GPx, and GR increased in Dvc. link3 Vitamin E supplementation resulted in increased MDA and CAT levels and reduced SOD activity. Conclusion In the SM glands of the diabetic rats, vitamin C supplementation improved the antioxidant system, while vitamin E acted as pro-oxidant.
