RESUMO

BACKGROUND: As most viruses remain uncultivated, metagenomics is currently the main method for virus discovery. Detecting viruses in metagenomic data is not trivial. In the past few years, many bioinformatic virus identification tools have been developed for this task, making it challenging to choose the right tools, parameters, and cutoffs. As all these tools measure different biological signals, and use different algorithms and training and reference databases, it is imperative to conduct an independent benchmarking to give users objective guidance. RESULTS: We compare the performance of nine state-of-the-art virus identification tools in thirteen modes on eight paired viral and microbial datasets from three distinct biomes, including a new complex dataset from Antarctic coastal waters. The tools have highly variable true positive rates (0-97%) and false positive rates (0-30%). PPR-Meta best distinguishes viral from microbial contigs, followed by DeepVirFinder, VirSorter2, and VIBRANT. Different tools identify different subsets of the benchmarking data and all tools, except for Sourmash, find unique viral contigs. Performance of tools improved with adjusted parameter cutoffs, indicating that adjustment of parameter cutoffs before usage should be considered. CONCLUSIONS: Together, our independent benchmarking facilitates selecting choices of bioinformatic virus identification tools and gives suggestions for parameter adjustments to viromics researchers.

RESUMO

Through infection and lysis of their coexisting bacterial hosts, viruses impact the biogeochemical cycles sustaining globally significant pelagic oceanic ecosystems. Currently, little is known of the ecological interactions between lytic viruses and their bacterial hosts underlying these biogeochemical impacts at ecosystem scales. This study focused on populations of lytic viruses carrying the B12-dependent Class II monomeric ribonucleotide reductase (RNR) gene, ribonucleotide-triphosphate reductase (Class II RTPR), documenting seasonal changes in pelagic virioplankton and bacterioplankton using amplicon sequences of Class II RTPR and the 16S rRNA gene, respectively. Amplicon sequence libraries were analyzed using compositional data analysis tools that account for the compositional nature of these data. Both virio- and bacterioplankton communities responded to environmental changes typically seen across seasonal cycles as well as shorter term upwelling-downwelling events. Defining Class II RTPR-carrying viral populations according to major phylogenetic clades proved a more robust means of exploring virioplankton ecology than operational taxonomic units defined by percent sequence homology. Virioplankton Class II RTPR populations showed positive associations with a broad phylogenetic diversity of bacterioplankton including dominant taxa within pelagic oceanic ecosystems such as Prochlorococcus and SAR11. Temporal changes in Class II RTPR virioplankton, occurring as both free viruses and within infected cells, indicated possible viral-host pairs undergoing sustained infection and lysis cycles throughout the seasonal study. Phylogenetic relationships inferred from Class II RTPR sequences mirrored ecological patterns in virio- and bacterioplankton populations demonstrating possible genome to phenome associations for an essential viral replication gene.

RESUMO

Inflammatory bowel disease (IBD) is a global health problem in which gut microbiota dysbiosis plays an important pathogenic role. However, the current drugs for IBD treatment are far from optimal. Previous researches indicated that parthenolide (PTL) had not only anti-cancer properties but also strong anti-inflammatory activities. Rationale: To investigate the protective effect of PTL on colon inflammation and demonstrate the underlying gut microbiota-dependent mechanism. Methods: Colon inflammation severity in mouse model was measured by body weight change, mortality, colon length, disease activity index (DAI) score, H&E staining and colonoscopy evaluation. Gut microbiota alteration and short-chain fatty acids (SCFAs) production were analyzed through 16S rRNA sequencing and targeted metabolomics. Luminex cytokine microarray and Enzyme-linked immunosorbent assay (ELISA) were conducted to measure the colon cytokines profile. The frequency of immune cells in lamina propria (LP) and spleen were phenotyped by flow cytometry. Results: The PTL-treated mice showed significantly relieved colon inflammation, as evidenced by a reduction in body weight loss, survival rate, shortening of colon length, DAI score, histology score and colonoscopy score. Notably, when the gut microbiota was depleted using antibiotic cocktails, the protective effect of PTL on colon inflammation disappeared. PTL treatment downregulated the level of proinflammatory cytokines, including IL-1ß, TNF-α, IL-6, and IL-17A and upregulated the immunosuppressive cytokine IL-10 in colon tissue. 16S rRNA sequencing indicated that PTL-treated mice exhibited much more abundant gut microbial diversity and flora composition. Targeted metabolomics analysis manifested the increased SCFAs production in PTL-treated mice. Additionally, PTL administration selectively upregulated the frequency of colonic regulatory T (Treg) cells as well as downregulated the ratio of colonic T helper type 17 (Th17) cells, improving the Treg/Th17 balance to maintain intestinal homeostasis. Gut microbiota depletion and fecal microbiota transplantation (FMT) was performed to confirm this gut microbiota-dependent mechanism. Conclusions: PTL ameliorated colon inflammation in a gut microbiota-dependent manner. The underlying protective mechanism was associated with the improved Treg/Th17 balance in intestinal mucosa mediated through the increased microbiota-derived SCFAs production. Collectively, our results demonstrated the role of PTL as a potential gut microbiota modulator to prevent and treat IBD.

RESUMO

Electric cell-substrate impedance sensing (ECIS) is an emerging technique for sensitively monitoring morphological changes of adherent cells in tissue culture. In this study, human mesenchymal stem cells (hMSCs) were exposed to different concentrations of carbonyl cyanide 4-(trifluoromethoxy)phenylhydrazone (FCCP) for 20 h and their subsequent concentration-dependent responses in micromotion and wound healing migration were measured by ECIS. FCCP disrupts ATP synthesis and results in a decrease in cell migration rates. To detect the change of cell micromotion in response to FCCP challenge, time-series resistances of cell-covered electrodes were monitored and the values of variance were calculated to verify the difference. While Seahorse XF-24 extracellular flux analyzer can detect the effect of FCCP at 3 µM concentration, the variance calculation of the time-series resistances measured at 4 kHz can detect the effect of FCCP at concentrations as low as 1 µM. For wound healing migration, the recovery resistance curves were fitted by sigmoid curve and the hill slope showed a concentration-dependent decline from 0.3 µM to 3 µM, indicating a decrease in cell migration rate. Moreover, dose dependent incline of the inflection points from 0.3 µM to 3 µM FCCP implied the increase of the half time for wound recovery migration. Together, our results demonstrate that partial uncoupling of mitochondrial oxidative phosphorylation reduces micromotion and wound healing migration of hMSCs. The ECIS method used in this study offers a simple and sensitive approach to investigate stem cell migration and its regulation by mitochondrial dynamics.

RESUMO

OBJECTIVE: To investigate whether coadministration of dextromethorphan (DM) could suppress morphine-induced hyperprolactinemia in female rats during pregnancy and throughout lactation. DESIGN: Controlled prospective study. SETTING: University research laboratory. ANIMAL(S): One hundred adult female Sprague-Dawley rats. INTERVENTION(S): Rats were randomly divided into four groups and were subcutaneously injected with either saline, morphine, morphine + DM, or DM alone twice a day, progressively increasing by 1 mg/kg at 7-day intervals from an initial dose of 2 mg/kg for both morphine and DM. Drug administration was continued during pregnancy. After the offspring were born, the doses injected into the dams were increased by 1 mg/kg every 2 weeks. MAIN OUTCOME MEASURE(S): Serum prolactin (PRL) concentration and dopamine turnover rate at the hypothalamus and pituitary. RESULT(S): Chronic morphine administration induced higher PRL concentrations than the control animals at mating, and at early and late pregnancy. In rats receiving DM coadministration, we did not observe any increase by morphine. Our neurochemical results showed that this effect of DM may be partly through blocking the effect of morphine on inhibition of tuberoinfundibular dopaminergic (TIDA) neuronal activity. CONCLUSION(S): The use of DM as an adjuvant in females receiving chronic morphine treatment may prevent morphine-induced hyperprolactinemia.

RESUMO

Co-administration of dextromethorphan (DM) with morphine during pregnancy and throughout lactation has been found to reduce morphine physical dependence and tolerance in rat offspring. No evidence was presented, however, for the effect of DM co-administered with morphine during pregnancy on morphine-induced reward and behavioral sensitization (possibly related to the potential to induce morphine addiction) in morphine-exposed offspring. Conditioned place preference and locomotor activity tests revealed that the p60 male offspring of chronic morphine-treated female rats were more vulnerable to morphine-induced reward and behavioral sensitization. The administration of a low dose of morphine (1 mg/kg, i.p.) in these male offspring also increased the dopamine and serotonin turnover rates in the nucleus accumbens, which implied that they were more sensitive to morphine. Co-administration of DM with morphine in the dams prevented this adverse effect of morphine in the offspring rats. Thus, DM may possibly have a great potential in the prevention of higher vulnerability to psychological dependence of morphine in the offspring of morphine-addicted mothers.

RESUMO

Thyroid storm is a rare but life-threatening condition caused by exaggerated thyrotoxic manifestations. Untreated thyroid storm is fatal, and the case fatality rate is 21% to 30%. The most important clinical management in thyroid storm is early recognition and treatment. We present the case of a previously healthy young woman in whom suspected gastrointestinal tract sepsis complicated by multi-organ dysfunction syndrome masked the major symptomatology of thyroid storm. This patient highlights the importance of a high clinical suspicion for potentially life-threatening conditions, such as thyroid storm, even in the absence of clinical clues (exophthalmos, lid lag, and goiter) or a history of thyrotoxicosis.

RESUMO

Both slow-release (SR) and regular-release (RR) metformin were effective in the treatment of type 2 diabetes mellitus. We compare the efficacy, safety, and effects on serum adipocytokines and inflammatory markers of both regimens in patients with type 2 diabetes mellitus. A prospective, randomized, double-blind study enrolled 55 patients with type 2 diabetes mellitus, which were randomly assigned to receive either metformin SR or RR (at a maximal dosage of 2000 mg/d for 12 weeks). Glycosylated hemoglobin A1c (HbA1c), fasting plasma glucose, adipocytokines, C-reactive protein, and insulin resistance and pancreatic beta-cell function were measured before and after treatment. Significant decreases (P<.001) in mean HbA1c and fasting plasma glucose levels were observed in each group. However, the mean changes in HbA1c from baseline to end point in the 2 groups were not significantly different. Changes in metabolic parameters were similar except that a decreased total cholesterol level was observed in the metformin RR group. Neither regimen treatment had any influence on insulin resistance, but metformin RR improved beta-cell function. Neither regimen had an effect on serum adipocytokines or inflammatory markers. Once-daily metformin SR was as safe and effective as metformin RR in type 2 diabetic patients. Neither dosage form affected serum adipocytokines and inflammatory markers.

RESUMO

OBJECTIVE: This study was designed to evaluate the effects of rosiglitazone (ROS) on insulin sensitivity, beta-cell function, and glycaemic response to glucose challenge and meal in subjects with impaired glucose tolerance (IGT). METHODS: Thirty patients with IGT (ages between 30 and 75 years and BMI (body mass index) < or = 27 kg/m2) were randomly assigned to receive either placebo (n = 15) or ROS (4 mg/day) (n = 15). All participants underwent a 75-g oral glucose tolerance test (OGTT), meal test, and frequently sampled intravenous glucose tolerance test (FSIGT) before and after the 12-week treatment. RESULTS: After 12 weeks of ROS treatment, there were significant increases in total cholesterol (TC) (4.25 +/- 0.22 vs 4.80 +/- 0.17 mmol/l, P < 0.001), high-density lipoprotein cholesterol (HDL-C) (1.25 +/- 0.07 vs 1.43 +/- 0.06 mmol/l, P < 0.05), and low-density lipoprotein cholesterol (LDL-C) (2.70 +/- 0.15 vs 3.37 +/- 0.17 mmol/l, P < 0.05) without changes in triglyceride concentration, TC/HDL-C and LDL-C/HDL-C ratio. Although the acute insulin response (AIR) to intravenous glucose and disposition index (measured as the ability of pancreatic beta-cell compensation in the presence of insulin resistance) remained unchanged, the insulin sensitivity (SI) and glucose effectiveness (SG) were remarkably elevated (0.38 +/- 0.06 vs 0.54 +/- 0.09 x 10(-5) min(-1)/pmol, P < 0.05; 0.017 +/- 0.002 vs 0.021 +/- 0.001 min(-1), P < 0.05, respectively) in the ROS group. The glucose, insulin, and c-peptide areas under curve (AUC) in response to OGTT and the glucose and insulin AUC during meal were significantly ameliorated in the ROS group. Five out of 15 (33%) and two out of 15 (13%) subjects treated with ROS and placebo, respectively, reversed to normal response during OGTT (P < 0.05). CONCLUSION: Rosiglitazone treatment significantly improved insulin resistance and reduced postchallenge glucose and insulin concentrations in patients with impaired glucose tolerance without remarkable effects on beta-cell secretory function.

RESUMO

OBJECTIVE: The present study was to compare the efficacy of a single daily dose of methimazole (MMI) and propylthiouracil (PTU) in the treatment of Graves' hyperthyroidism. BACKGROUND: Antithyroid drugs, MMI and PTU, are widely used in the treatment of hyperthyroidism. Previous studies in the treatment of hyperthyroidism with a single daily dose of antithyroid drugs have demonstrated a more favourable result with MMI. However, the efficacy of a single daily dose of PTU was inconsistent. In this study, we examined the therapeutic efficacy of single daily doses of MMI and PTU on the change of thyroid hormones and thyrotropin receptor antibodies (TRAb) levels. METHODS: Thirty patients with newly diagnosed Graves' hyperthyroidism were randomly divided into two groups, each receiving a single dose of either 15 mg MMI or 150 mg PTU daily for 12 weeks. The therapeutic efficacy was determined by serum total triiodothyronine (TT3), total thyroxine (TT4), thyrotropin (TSH), free thyroxine (FT4), and TRAb levels at baseline and at the end of 4, 8 and 12 weeks during the study period. RESULTS: There was no significant difference in baseline thyroid function parameters. Serum TT3, TT4 and FT4 levels in the MMI-treated group were significantly lower than those of the PTU-treated group after 4 weeks and through the end of the study. MMI also has superior effect on reducing serum TRAb levels than PTU after 8 weeks and at the end of the study. CONCLUSION: During the 12-week treatment of Graves' hyperthyroidism, a single daily dose of 15 mg MMI was much more effective in the induction of euthyroidism than a single daily dose of 150 mg PTU. In the doses used in this study, MMI is preferable to PTU when a once-daily regimen of antithyroid drug is considered for the treatment of Graves' hyperthyroidism.

RESUMO

Many studies showed that depression is correlated with osteoporosis, while others showed that low cholesterol level is also related to depression. However, these relationships still remain controversial. Since the bone mineral density (BMD) is related to depression and depression is related to hypocholesterolemia, there might exist a correlation between BMD and plasma cholesterol levels. To prove this, we enrolled 5000 individuals, 2170 males, and 2830 females, who had health check-ups at a private clinic between 1998 and 1999. They were divided into three groups. Group 1 was composed of male subjects; Group 2, female subjects; and Group 3, females aged over 50 to exclude pre-menopausal females. Each subject had a routine physical examination, fasting blood drawing, BMD measured by dual energy x-ray absorptiometry (DEXA) over the wrist, and was given a questionnaire to answer. Between Groups 1 and 2, the females were significantly younger, had higher body mass index (BMI), total cholesterol (TC), high density lipoprotein cholesterol (HDLC), low density lipoprotein cholesterol (LDLC), and platelet, but lower BMD, fasting plasma glucose (FPG), triglycerides (TG), hemoglobin (Hgb), and white blood cell (WBC) count. As for Groups 1 and 3, all the aforementioned findings still remained the same except that the systolic blood pressure (SBP) was higher and diastolic blood pressure (DBP) was lower in Group 3. Our results showed that BMD is negatively related to age in males. In females, it is negatively correlated with age, FPG, PPG, SBP, DBP, TC, LDLC, TG, and Hgb, but positively related to BMI and platelet. However, for females in Group 3, BMD is only negatively related to age, FPG, SBP, and TG but positively related to BMI. Stepwise multiple regression analysis showed that the BMD is negatively related to age but positively related to BMI in both males and females. In Group 3, BMD is negatively related to age and FPG but positively related BMI. In conclusion, no correlation exists between BMD and cholesterol. This implies that the depression is not significantly related to cholesterol and/or BMD. This might be due to various confounding factors, which could affect their relationships. The negative correlation between BMD and FPG is only observed in females older than 50 years. Further studies are needed to clarify these relationships.

RESUMO

BACKGROUND: To evaluate the effect of the sustained-release formulation of indapamide (indapamide SR) in type 2 diabetic patients with mild-to-moderate hypertension and its possible side effects, particularly on glucose metabolism and lipid profiles. METHODS: A total of 64 patients randomly received 1.5 mg of indapamide SR or placebo once daily for 3 months. The effects were evaluated by 24-h ambulatory blood pressure monitor, fasting blood sampling for biochemistry, lipid profiles, and frequently sampled intravenous glucose tolerance test. RESULTS: The changes in standing and supine blood pressure (BP) were significant (154.7 +/- 9.4/94 +/- 2.9 mm Hg v 134.4 +/- 5.1/82.4 +/- 5 mm Hg and 155 +/- 9.8/94.6 +/- 3.6 mm Hg v 135.1 +/- 4.9/82.1 +/- 4.7 mm Hg) in the indapamide group, but not in the placebo group. According to the 24-h ambulatory blood pressure monitor reading, a significant reduction was observed in not only in the whole-day mean BP (mean systolic BP/mean diastolic BP, 149 +/- 19.3/87.6 +/- 11.3 mm Hg v 135.7 +/- 12.6/79.6 +/- 9 mm Hg) but also the whole-day mean median arterial pressure (109 +/- 12.7 mm Hg v 98.7 +/- 8.2 mm Hg) for the indapamide group, but not the placebo group. There were no changes in biochemical data including serum sodium, potassium, chloride, uric acid, alanine aminotransferase, aspartate aminotransferase, blood urea nitrogen, creatinine, lipid profiles, fasting blood glucose, insulin, hemoglobin Alc, and glucose metabolism parameters (insulin sensitivity, glucose effectiveness, and acute insulin response) from frequently sampled intravenous glucose tolerance test after indapamide or placebo therapy. CONCLUSIONS: Indapamide SR can significantly lower the whole-day BP in hypertensive patients with type 2 diabetes. Also, it did not alter or aggravate patients' lipid profiles, glucose metabolism, and did not exert possible side effects of hypokalemia and hyperuricemia. Therefore, monotherapy with indapamide SR should be suggested in type 2 diabetic patients with mild-to-moderate hypertension.
