RESUMO

BACKGROUND: Although the fetal sphericity index (SI) and fractional shortening (FS) of 24 transverse segments have been previously reported after the 20th gestational week, there have been no reports during the first and early second trimester. OBJECTIVE: This study aimed to clarify the SI and FS of 24 transverse segments in normal fetuses before the 20th gestational week. METHODS: A total of 101 normal fetuses aged between 12 and 20 gestational weeks were examined. The displacement of the ventricular endocardium during the cardiac cycle was computed using speckle-tracking software (GE Healthcare, Milwaukee, WI). We analyzed the length of 24 end-diastolic lateral segments and the end-diastolic basal (seg1-6)- middle (Seg7-15)-apical (Seg16-24) distribution from the base to the apex of each ventricle, according to the method described by DeVore et al. The SI and FS were computed for each of the 24 segments by dividing the mid-basal-apical length by the transverse size. RESULTS: The SI for each segment was independent of the gestational age. The SI of the right ventricle was significantly lower than that of the left ventricle for segments 1-14, suggesting that the right ventricle was more spherical than the left ventricle in the basal segment only. The FS of the right ventricle was significantly lower than that of the left ventricle in segments 1 to 2 and 13 to 24. CONCLUSION: The morphology of the ventricles before 20 weeks of gestation differs from that between 20 and 40 weeks of gestation. This difference may be related to myocardial densification or performance.

RESUMO

BACKGROUND: Chronic rhinosinusitis (CRS) is a common chronic inflammatory disease and is subdivided into eosinophilic and noneosinophilic forms. There are few reports investigating the nasal microbiome and its pathological functions in patients with CRS. OBJECTIVE: We sought to analyze factors contributing to variations of the nasal microbiome in CRS, and on the basis of these factors, to elucidate whether the bacterial metabolites were related to the pathogenesis. METHODS: Nasal swabs were collected, and the V3 to V4 variable region of the 16S ribosomal RNA gene was amplified and sequenced. Factors contributing to variations of the nasal microbiome in patients with CRS were compared. The most influential factor was whether CRS was eosinophilic, and we compared α- and ß-diversity, bacterial species, and predictive bacterial functions between the 2 patient groups. In addition, the metabolites of the key bacteria were extracted, and we evaluated the predicted bacterial functions in airway epithelial cells. RESULTS: In total, 110 patients with CRS and 33 control subjects were enrolled. On the basis of the factors of variation, it was found that patients with eosinophilic CRS (n = 65) had different microbiomes with weighted UniFrac ß-diversity and lower α-diversity compared with those with noneosinophilic CRS (n = 45). A higher abundance of Fusobacterium nucleatum and an increased LPS pathway were observed in patients with noneosinophilic CRS compared with those with eosinophilic CRS. In airway epithelial cells, LPS derived from F nucleatum suppressed the expression levels of ALOX15 induced by TH2 cytokines. CONCLUSIONS: The differences in the nasal microbiome may play a key role in the pathophysiology of CRS.

RESUMO

BACKGROUND: Intestinal bacteria may play a role in the development of food allergies. This study aimed to analyze and compare the gut microbiota of food-allergic children with that of healthy children of the same age. METHODS: Stool samples were collected from one-and-a-half-year-old food-allergic (FA group, n = 29) and healthy controls (HC group, n = 19). A questionnaire was provided to examine the children's birth, dietary, medical, and social histories. The gut microbiota was profiled by 16S rRNA sequencing. Differences in taxonomic composition were assessed using linear discriminant analysis effect size (LEfSe), and microbial functional profiles were predicted with Tax4Fun2. RESULTS: No significant difference in the alpha diversity index between the two groups; however, a negative correlation was observed between the Shannon diversity index and the relative abundance of Bacteroides. A significant difference was observed in beta diversity (permutational multivariate analysis of variance) in the bacterial composition between the FA and HC groups (P < 0.05). The FA group had a higher abundance of Escherichia and Anaeromassilibacillus and a lower abundance of Bacteroides, Oscillibacter, Ruminococcus, Hungateiclostridium and Anaerotaenia than the HC group (LEfSe: linear discriminant analysis score >2). The FA group showed a predicted increase in the expression levels of genes associated with intestinal pathogenicity compared with that in the HC group. CONCLUSIONS: The gut microbiota of food-allergic children has a higher abundance of bacteria involved in intestinal inflammation and a lower abundance of bacteria involved in immune tolerance than that of healthy children. This dysbiosis may also be associated with food allergies.

RESUMO

OBJECTIVES: A marked prolongation of the prothrombin time-international normalized ratio (PT-INR) is frequently observed during biliary obstruction in patients using warfarin. The objective of this study was to identify factors associated with PT-INR prolongation during biliary obstruction in patients using warfarin. METHODS: Among 44 patients using warfarin who had biliary obstruction, we retrospectively investigated warfarin doses and laboratory data before and during biliary obstruction. The primary outcome was the association between changes in PT-INR (ΔPT-INR) and changes in laboratory data before and during biliary obstruction. RESULTS: Median PT-INR was 1.59 (IQR 1.38-1.95) before biliary obstruction and 2.27 (IQR 1.60-3.49) during biliary obstruction, indicating significant prolongation during the obstruction (P < 0.001). ΔPT-INR showed strong positive correlations with change in total bilirubin (ΔT-Bil; ρ = 0.692, P < 0.001) and change in conjugated bilirubin (ΔC-Bil; ρ = 0.731, P < 0.001). ΔPT-INR showed a weak negative correlation with the change in albumin (ΔAlb; ρ = -0.371, P < 0.05). When ΔPT-INR was used as the dependent variable in multiple linear regression analysis, ΔT-Bil, ΔC-Bil, and ΔAlb were significantly associated with ΔPT-INR. CONCLUSIONS: PT-INR was prolonged during biliary obstruction in patients using warfarin, and changes in bilirubin levels were associated with ΔPT-INR. If biliary obstruction with markedly elevated bilirubin levels occurs, measuring PT-INR could lead to safer warfarin therapy.

RESUMO

OBJECTIVES: Diagonal echogenic lines outside the lateral ventricle have often been observed in the anterior coronal planes of the normal fetal brain by neurosonography. We have observed abnormal shapes of these echogenic lines in cases of malformation of cortical development (MCD). We named the ultrasound finding "cat-ear-line" (CEL). This study aimed to examine how and when CEL develops in normal cases compared with MCD cases. METHODS: We retrospectively examined the fetal brain volume dataset acquired through transvaginal 3D neurosonography of 575 control cases and 39 MCD cases from 2014 to 2020. We defined CEL as the hyperechogenic continuous lines through subplate (SP) and intermediate zone (IZ), pre-CEL as the lines that existed only within the SP, and abnormal CEL as a mass-like or mosaic shadow-like structure that existed across the SP and IZ. All fetuses in the MCD group had some neurosonographic abnormalities and were ultimately diagnosed with MCD. RESULTS: The CEL was detected in 97.9% (369/377) of the control group from 19 to 30 weeks. The CEL visualization rate of the MCD group in the same period was 40.0% (14/35) which was significantly lower than that of the control group (P < .001). CONCLUSIONS: From this study, it appears that the CEL is an ultrasound finding observed at and beyond 19 weeks in a normally developing fetus. In some MCD cases, pre-CEL at and beyond 19 weeks or abnormal CEL was observed. Maldeveloped CEL at mid-trimester may help identify cases at-risk of subsequent MCD.

RESUMO

PURPOSE: Anastomotic leakage is a potential complication after colorectal surgery. We investigated the effects of oral antibiotics and a low-residue diet on the incidence of anastomotic leakage after left-sided colorectal surgery. METHODS: Outcomes were retrospectively compared between 64 patients who underwent mechanical bowel preparation alone (group A) and 183 patients who underwent mechanical bowel preparation with addition of oral kanamycin and metronidazole (group B) on the day before left-sided colorectal surgery. After surgery, patients in group A received a normal diet containing dietary fiber and those in group B received a low-residue diet. The primary outcome was the incidence of anastomotic leakage. Secondary outcomes were rates of other postoperative complications, length of postoperative hospital stay, and laboratory data. RESULTS: Anastomotic leakage, surgical site infection, and diarrhea were less common in group B than in group A (4.9% vs 18.8%, 6.6% vs 23.4%, and 25.7% vs 43.8%, respectively). Postoperative C-reactive protein levels were significantly lower in group B. The median postoperative hospital stay was significantly shorter in group B than in group A (8 days vs 9 days, P = 0.010). Adaptive double least absolute shrinkage and selection operator regression revealed that use of preoperative oral antibiotics and a postoperative low-residue diet were associated with lower incidence of anastomotic leakage (odds ratio 0.163, 95% confidence interval 0.062-0.430; P < 0.001). CONCLUSION: Oral antibiotics and a low-residue diet reduced the incidence of anastomotic leakage and shortened the postoperative hospital stay by 1 day.

RESUMO

Mentha is a complex genus encompassing many species as a consequence of their interspecific hybridization and polyploidy. Southeast Asian mints have been poorly distinguished though they are widely used for culinary and medical purposes. In this study, we have analyzed Southeast Asian mints and known varieties as well as a related Lamiaceae species (Nepeta sp.) using simple sequence repeat (SSR) markers and leaf morphology. Two types of mints were clearly distinguished based on their venation pattern and leaf shape index. We developed 12 SSR markers that allowed good amplification in the Mentha and another Lamiaceae species. In the SSR-based phylogram, the Mentha lines could be delimited into groups I-VI. The Southeast Asian mints divided into groups I and II, and the phylogram separated most of the available species, with groups I and II containing the known species M. × cordifolia and M. arvensis, respectively. The separation of the two groups was supported by a population structure analysis. The SSR markers developed in this study enabled the simultaneous classification of mints and will help improve our understanding of the genetic composition of known mint varieties and as yet unclassified Southeast Asian mints.

RESUMO

Neoantigens have attracted attention as biomarkers or therapeutic targets. However, accurate prediction of neoantigens is still challenging, especially in terms of its accuracy and cost. Variant detection using RNA sequencing (RNA-seq) data has been reported to be a low-accuracy but cost-effective tool, but the feasibility of RNA-seq data for neoantigen prediction has not been fully examined. In the present study, we used whole-exome sequencing (WES) and RNA-seq data of tumor and matched normal samples from six breast cancer patients to evaluate the utility of RNA-seq data instead of WES data in variant calling to detect neoantigen candidates. Somatic variants were called in three protocols using: (i) tumor and normal WES data (DNA method, Dm); (ii) tumor and normal RNA-seq data (RNA method, Rm); and (iii) combination of tumor RNA-seq and normal WES data (Combination method, Cm). We found that the Rm had both high false-positive and high false-negative rates because this method depended greatly on the expression status of normal transcripts. When we compared the results of Dm with those of Cm, only 14% of the neoantigen candidates detected in Dm were identified in Cm, but the majority of the missed candidates lacked coverage or variant allele reads in the tumor RNA. In contrast, about 70% of the neoepitope candidates with higher expression and rich mutant transcripts could be detected in Cm. Our results showed that Cm could be an efficient and a cost-effective approach to predict highly expressed neoantigens in tumor samples.

RESUMO

WHAT IS KNOWN AND OBJECTIVE: Vitamin K deficiency is known to cause impaired coagulation. We report a case of marked prolongation of the prothrombin time-international normalized ratio (PT-INR) associated with warfarin and vitamin K deficiency caused by endoscopic nasobiliary drainage (ENBD). CASE PRESENTATION: Oral administration of warfarin was initiated in a 67-year-old man after left hemihepatectomy. He developed a biliary fistula after surgery that was treated by ENBD, which resulted in significant prolongation of the PT-INR. WHAT IS NEW AND CONCLUSION: The effect of warfarin was enhanced in this patient due to reduced absorption of vitamin K as a result of external biliary drainage.

RESUMO

BACKGROUND: Global ischemia due to cardiac arrest (CA) followed by cardiopulmonary resuscitation (CPR) causes significant neuronal damage in vulnerable areas in the brain. Currently, a majority of patients eventually die after successful CPR due to neurological injury. Statins have pleiotropic effects including anti-inflammatory and/or antioxidant responses. These pleiotropic effects can have a beneficial role in the post-CPR phase. We tested whether two different types of statins, hydrophilic pravastatin and lipophilic simvastatin, attenuated neurological injury following CA/CPR. The efficacy of pravastatin and simvastatin combination treatment was also assessed. METHODS: Isoflurane-anesthetized adult male wild-type C57Bl/6 mice subjected to 8-min CA/CPR were randomized into four groups: control, 2 mg/kg pravastatin, 20 mg/kg simvastatin, or a combination of 3 mg/kg pravastatin and 10 mg/kg simvastatin. Neurobehavioral assessment and histological analyses were performed to assess overall general health condition and neuronal injury, respectively. RESULTS: Combination treatment with pravastatin and simvastatin significantly reduced neuronal injury in the striatum and hippocampus, reduced cerebral edema, and improved general health at 4 days after CA/CPR. Combination statin treatment upregulated endothelial nitric oxide synthase mRNA in the brain. Pravastatin alone, but not simvastatin alone, improved general health after CA/CPR. Pravastatin was less potent than simvastatin at reducing neuronal injury in the brain. CONCLUSION: Combination treatment with two different types of statins at the correct dose may be a promising approach to neuroprotection following CA/CPR.

RESUMO

BACKGROUND: Cerebral edema is one of the major causes of mortality following cardiac arrest (CA) and cardiopulmonary resuscitation (CPR). A subunit of the sulfonylurea receptor 1-transient receptor potential M4 (Sur1-TRPM4) channel has been implicated in the pathogenesis of ischemia-evoked cerebral edema. In this study, we examined whether glibenclamide (GBC), a Sur1-TRPM4 channel inhibitor, attenuates cerebral edema following CA/CPR and further examined the efficacy of GBC combined with therapeutic hypothermia. METHODS: Isoflurane-anesthetized adult male wild-type C57Bl/6 mice subjected to 7-min CA/CPR were randomized into five groups: sham operation, control with normothermia, GBC with normothermia, control with hypothermia, and GBC with hypothermia. The primary outcome was to evaluate regional brain water content; the secondary outcome was to measure blood glucose level, Sur1-TRPM4 expression, and pro-inflammatory factor expression. RESULTS: Compared with normothermia, GBC treatment or hypothermia significantly attenuated brain water content in mice subjected to CA/CPR. GBC combined with hypothermia had no additional effects on attenuating cerebral edema. Pro-inflammatory factor messenger RNA expression (TNF-α and IL-6), NFκß activation, and SUR1-TRPM4 levels were upregulated after CA/CPR. Compared with normothermia, hypothermia, but not GBC, partly suppressed these factors' expression. CONCLUSIONS: GBC attenuated cerebral edema following CA/CPR by blocking Sur1-TRPM4 channels upregulated by CA insult. The effect of GBC was comparable with that of therapeutic hypothermia alone. These results suggest that GBC is an alternative approach for treating CA-evoked cerebral edema.

RESUMO

We recently reported that 4-methylthio-3-butenyl isothiocyanate (MTBITC) exerts chemopreventive effects on the rat esophageal carcinogenesis model at a low dose of 80 ppm in a diet. In contrast, some isothiocyanates (ITCs) have been reported to cause toxic effects, promotion activity, and/or carcinogenic potential in the urinary bladder of rats. In the present study, we investigated whether MTBITC had toxic effects in the urinary bladder similar to other ITCs, such as phenethyl ITC (PEITC). First, to examine the early toxicity of MTBITC, rats were fed a diet supplemented with 100, 300 or 1000 ppm MTBITC for 14 days. Treatment with 1000 ppm MTBITC caused increased organ weights and histopathological changes in the urinary bladder, producing lesions similar to those of 1000 ppm PEITC. In contrast, rats treated with 100 or 300 ppm MTBITC showed no signs of toxicity. Additionally, we performed in vivo genotoxicity studies to clarify whether MTBITC may exhibit a carcinogenic potential through a genotoxic mechanism in rats. Rats were treated with MTBITC for 3 days at doses of 10, 30 or 90 mg kg-1 body weight by gavage, and comet assays in the urinary bladder and micronucleus assays in the bone marrow were performed. No genotoxic changes were observed after treatment with MTBITC at all doses. Overall, these results suggested that the effects of MTBITC in the rat urinary bladder are less than those of PEITC, but that MTBITC could have toxic effects through a nongenotoxic mechanism in the urinary bladder of rats at high doses.

RESUMO

To examine the effects of 4-methylthio-3-butenyl isothiocyanate on esophageal carcinogenesis, male 6-week-old F344 rats were subcutaneously injected with 0.5 mg/kg body weight N-nitrosomethylbenzylamine three times per week for 5 weeks and fed a diet supplemented with 80 ppm 4-methylthio-3-butenyl isothiocyanate, equivalent to 6.05 mg/kg body weight/day for the initiation stage, 4.03 mg/kg body weight/day for the promotion stage, or 4.79 mg/kg body weight/day for all stages. Although the incidence of lesions was not affected by 4-methylthio-3-butenyl isothiocyanate treatment, the multiplicity of squamous cell papilloma in the esophagus was significantly decreased in rats in the 4-methylthio-3-butenyl isothiocyanate initiation stage group (1.13 ± 0.74), 4-methylthio-3-butenyl isothiocyanate promotion stage group (1.47 ± 0.99), and 4-methylthio-3-butenyl isothiocyanate all stage group (1.47 ± 1.13) as compared with rats treated with N-nitrosomethylbenzylamine alone (3.00 ± 1.46). Immunohistochemical analysis revealed that 4-methylthio-3-butenyl isothiocyanate induced apoptosis, suppressed cell proliferation, and increased p21 expression when administered in the promotion phase. These modifying effects were not observed in the rats treated with 4-methylthio-3-butenyl isothiocyanate alone. Our results indicated that 4-methylthio-3-butenyl isothiocyanate may exert chemopreventive effects against N-nitrosomethylbenzylamine-induced esophageal carcinogenesis in rats.

RESUMO

We have prepared nearly perfect hexagonal m-plane-oriented RbxWO3 films on (010)-oriented RbLaNb2O7 layers. The prepared bilayer films showed Rb diffusion from the RbLaNb2O7 seed layers, and we obtained uniaxially oriented RbxWO3/Rb1-yLaNb2O7 photoanodes. The RbxWO3/Rb1-yLaNb2O7 bilayer photoanodes exhibited enhanced photoelectrochemical water splitting compared with the RbxWO3 and RbLaNb2O7 monolayer photoanodes. Furthermore, we clearly demonstrated that the high crystal quality of the heterojunction significantly enhanced water splitting. The photocurrent density of the nearly perfectly oriented RbxWO3/Rb1-yLaNb2O7 photoanode that we prepared was 9.4-fold that of an unoriented bilayer photoanode. This increase was attributed to the inhibition of photo-excited charge recombination and stimulated electron transfer derived from low grain-boundary resistance.

RESUMO

A 44-year-old woman was admitted to the hospital for asymptomatic gross hematuria. At the age of 28, she underwent transplantation of a kidney from her father for end-stage renal disease secondary to rapidly progressive glomerulonephritis. She resumed peritoneal dialysis when the allograft kidney stopped functioning at the age of 42. Dialysis was continued for the next 2 years, when the hematuria occurred and she was readmitted. Radiologic evaluation and transurethral resection of the bladder tumor revealed a tumor of the renal pelvis of the allograft kidney (cT3N0M0) and multiple bladder tumors (cT1N0M0). Total cystectomy and allograft nephroureterectomy were performed. Histopathological examinations revealed high grade urothelial carcinoma in the renal pelvis of the allograft kidney (pT3) and native bladder (pT1). Fluorescence in situ hybridization of both specimens demonstrated that the renal pelvic tumors and bladder cancer possessed XY karyotypes. These results indicated that the urothelial carcinoma developed de novo in the renal pelvis of the allograft kidney and was implanted into the recipient's native bladder.

RESUMO

Methylthioacetic acid (MTA) is an acid-hydrolyzed derivative of a natural aroma compound, methylthioacetic acid ethyl ester isolated from Cucumis melo var. conomon (Katsura-uri, Japanese Picking Melon), and induces a villiform-like structure dome in RCM-1 human colorectal cancer cell culture. Thus far, the physiological and molecular properties of MTA-mediated dome formation remain unknown. Herein, MTA (not more than 2 mM) was demonstrated to differentiate the unorganized cell mass into the dome in RCM-1 cell culture by disclosing the correlation between dome formation and several intestinal differentiation markers such as alkaline phosphatase activity and the protein levels of dipeptidyl peptidase 4, villin, and Krüppel-like factor 4. Dome formation in RCM-1 cell culture was additively enhanced by the simultaneous administration of MTA and butyric acid (BA), suggesting that MTA directs the differentiation of RCM-1 cells, potentially through the same or similar pathway(s) shared with BA. Notably, a high dose of MTA (2 mM or more) elevated several apoptosis markers, such as DNA fragmentation, caspase-3/7 activity, and cleavage of poly(ADP-ribose) polymerase. Altogether, in addition to RCM-1 cell differentiation, MTA triggers apoptosis. These results indicate that MTA is a potential anticarcinogenic agent applicable in differentiation therapy and traditional chemotherapy against colorectal cancers.

RESUMO

Background: Allergic diseases are some of the most common diseases worldwide. Genome-wide association studies (GWASs) have been conducted to elucidate the genetic factors of allergic diseases. However, no GWASs for allergen component sensitization have been performed. Objective: We sought to detect genetic variants associated with differences in immune responsiveness against allergen components. Methods: The participants of the present study were recruited from the Tokyo Children's Health, Illness, and Development study, and allergen component-specific IgE level at age 9 years was measured by means of allergen microarray immunoassays. We performed GWASs for allergen component sensitization against each allergen (single allergen component sensitization, number of allergen components analyzed, n = 31), as well as against allergen protein families (allergen protein group sensitization, number of protein groups analyzed, n = 16). Results: We performed GWAS on 564 participants of the Tokyo Children's Health, Illness, and Development study and found associations between Amb a 1 sensitization and the immunoglobulin heavy-chain variable gene on chromosome 14 and between Phl p 1 sensitization and the HLA class II region on chromosome 6 (P < 5.0 × 10-8). A GWAS-significant association was also observed between the HLA class II region and profilin sensitization (P < 5.0 × 10-8). Conclusions: Our data provide the first demonstration of genetic risk for allergen component sensitization and show that this genetic risk is related to immune response genes including immunoglobulin heavy-chain variable gene and HLA.

RESUMO

Two key transcription factors (TFs) in brassinosteroid (BR) signaling BRASSINOSTEROID INSENSITIVE 1-EMS-SUPPRESSOR 1 (BES1) and BRASSINAZOLE RESISTANT 1 (BZR1), belong to a small family with four BES1/BZR1 homologs (BEH1-4). To date, in contrast to the wealth of knowledge regarding BES1 and BZR1, little is known about BEH1-4. Here, we show that BEH2 was expressed preferentially in the roots and leaf margins including serrations, which was quite different from another member BEH4, and that BRs downregulated BEH2 through a module containing GSK3-like kinases and BES1/BZR1 TFs, among which BES1, rather than BZR1, contributed to this process. In addition, BEH2 consistently existed in the nucleus, suggesting that its subcellular localization is not under BR-dependent nuclear-cytoplasmic shuttling control. Furthermore, gene ontology analysis on RNA-seq data indicated that BEH2 may be implicated in stress response and photosynthesis. These findings might assist in the future elucidation of the molecular mechanisms underlying BR signaling.
