RESUMO

Exploring the ratiometric fluorescence biosensing of DNA-templated biemissive silver nanoclusters (AgNCs) is significant in bioanalysis, yet the design of a stimuli-responsive DNA device is a challenge. Herein, using the anti-digoxin antibody (anti-Dig) with two identical binding sites as a model, a tweezer-like DNA architecture is assembled to populate fluorescent green- and red-AgNCs (g-AgNCs and r-AgNCs), aiming to produce a ratio signal via specific recognition of anti-Dig with two haptens (DigH). To this end, four DNA probes are programmed, including a reporter strand (RS) dually ended with a g-/r-AgNC template sequence, an enhancer strand (ES) tethering two same G-rich tails (G18), a capture strand (CS) labeled with DigH at two ends, and a help strand (HS). Initially, both g-AgNCs and r-AgNCs wrapped in the intact RS are nonfluorescent, whereas the base pairing between RS, ES, CS, and HS resulted in the construction of DNA mechanical tweezers with two symmetric arms hinged by a rigid "fulcrum", in which g-AgNCs are lighted up due to G18 proximity ("green-on"), and r-AgNCs away from G18 are still dark ("red-off"). When two DigHs in proximity recognize and bind anti-Dig, the conformation switch of these tweezers resultantly occurs, taking g-AgNCs away from G18 for "green-off" and bringing r-AgNCs close to G18 for "red-on". As such, the ratiometric fluorescence of r-AgNCs versus g-AgNCs is generated in response to anti-Dig, achieving reliable quantization with a limit of detection at the picomolar level. Based on the fast stimulated switch of unique DNA tweezers, our ratiometric strategy of dual-emitting AgNCs would provide a new avenue for a variety of bioassays.

RESUMO

Designing antibody-powered DNA nanodevice switches is crucial and fascinating to perform a variety of functions in response to specific antibodies as regulatory inputs, achieving highly sensitive detection by integration with simple amplified methods. In this work, we report a unique DNA-based conformational switch, powered by a targeted anti-digoxin mouse monoclonal antibody (anti-Dig) as a model, to rationally initiate the hybridization chain reaction (HCR) for enzyme-free signal amplification. As a proof-of-concept, both a fluorophore Cy3-labeled reporter hairpin (RH) in the 3' terminus and a single-stranded helper DNA (HS) were individually hybridized with a recognition single-stranded DNA (RS) modified with Dig hapten, while the unpaired loop of RH was hybridized with the exposed 3'-toehold of HS, isothermally self-assembling an intermediate metastable DNA structure. The introduction of target anti-Dig drove the concurrent conjugation with two tethered Dig haptens, powering the directional switch of this DNA structure into a stable conformation. In this case, the unlocked 3'-stem of RH was implemented to unfold the 5'-stem of the BHQ-2-labeled quench hairpin (QH), rationally initiating the HCR between them by the overlapping complementary hybridization. As a result, numerous pairs of Cy3 and BHQ-2 in the formed long double helix were located in spatial proximity. In response to this, the significant quenching of the fluorescence intensity of Cy3 by BHQ-2 was dependent on the variable concentration of anti-Dig, achieving a highly sensitive quantification down to the picomolar level based on a simplified protocol integrated with enzyme-free amplification.

RESUMO

In mammals, mature miR-122 is 22 nucleotides long and can be involved in regulating a variety of physiological and biological pathways. In this study, the expression profile and effects of grouper Epinephelus coioides miR-122 response to Singapore grouper iridovirus (SGIV) infection were investigated. The sequences of mature microRNAs (miRNAs) from different organisms are highly conserved, and miR-122 from E. coioides exhibits high similarity to that from mammals and other fish. The expression of miR-122 was up-regulated during SGIV infection. Up-regulation of miR-122 could significantly enhance the cytopathic effects (CPE) induced by SGIV, the transcription levels of viral genes (MCP, VP19, LITAF and ICP18), and viral replication; reduce the expression of inflammatory factors (TNF-a, IL-6, and IL-8), and the activity of AP-1 and NF-κB, and miR-122 can bind the target gene p38α MAPK to regulate the SGIV-induced cell apoptosis and the protease activity of caspase-3. The results indicated that SGIV infection can up-regulate the expression of E. coioides miR-122, and up-regulation of miR-122 can affect the activation of inflammatory factors, the activity of AP-1 and NF-κB, and cell apoptosis to regulate viral replication and proliferation.

RESUMO

Programmed cell death 4 (PDCD4) in mammals, a gene closely associated with apoptosis, is involved in many biological processes, such as cell aging, differentiation, regulation of cell cycle, and inflammatory response. In this study, grouper Epinephelus coioides PDCD4, EcPDCD4-1 and EcPDCD4-2, were obtained. The open reading frame (ORF) of EcPDCD4-1 is 1413 bp encoding 470 amino acids with a molecular mass of 52.39 kDa and a theoretical pI of 5.33. The ORF of EcPDCD4-2 is 1410 bp encoding 469 amino acids with a molecular mass of 52.29 kDa and a theoretical pI of 5.29. Both EcPDCD4-1 and EcPDCD4-2 proteins contain two conserved MA3 domains, and their mRNA were detected in all eight tissues of E. coioides by quantitative real-time PCR (qRT-PCR) with the highest expression in liver. The expressions of two EcPDCD4s were significantly up-regulated after Singapore grouper iridovirus (SGIV) or Vibrio alginolyticus infection. In addition, over-expression of EcPDCD4-1 or EcPDCD4-2 can inhibit the activity of the nuclear factor-κB (NF-κB) and activator protein-1 (AP-1), and regulate SGIV-induced apoptosis. The results demonstrated that EcPDCD4s might play important roles in E. coioides tissues during pathogen-caused inflammation.

RESUMO

The nuclear factor-κB (NF-κB) family is evolutionary conserved and plays key roles in the regulation of numerous basic cellular processes. In this study, a sea cucumber Holothuria leucospilota NF-κB1 p105 named HLp105 was first obtained. The full-length cDNA of HLp105 is 6564 bp long, with a 219 bp 5' untranslated region (UTR), a 2979 bp 3' UTR, and a 3366 bp open reading frame (ORF) encoding for 1121 amino acids with a deduced molecular weight of 123.92 kDa and an estimated pI of 5.31. HLp105 protein contains the conserved domain RHD, IPT, ANK and DEATH. HLp105 mRNA can be detected in all tissues examined, with the highest level in the intestine, followed by the transverse vessel, rete mirabile, coelomocytes, respiratory tree, bolishiti, cuvierian tubules, body wall, oesophagus and muscle. Challenged by LPS or poly (I:C), the transcription level of HLp105 was apparently up-regulated in the tissues examined. Besides, Over-expression of HLp105 in HEK293T cells, the apoptosis was inhibited, and the cytokines IL-1ß and TNF-α were activated. The results are important for better understanding the function of NF-κB1 p105 in sea cucumber and reveal its involvement in immunoreaction.

RESUMO

BACKGROUND AND OBJECTIVES: Myricetin is a flavonoid compound that is abundant in teas, red wine, berries, herbs and vegetables with a variety of pharmacological properties such as antioxidant, anti-inflammatory and anti-cancer effects. Although there are in vitro studies showing that myricetin inhibits human cytochrome P450 (CYP) 2D6 and CYP3A, the inhibitory mechanisms of myricetin on CYP enzymes are still unclear. The aim of this study was to evaluate the inhibitory effects of myricetin on human and rat CYPs, including CYP3A2/3A4, CYP2B1/2B6, CYP2C9/2C11 and CYP2D1/2D6. METHODS: This study was performed to investigate the inhibitory effects of myricetin on human CYP3A4, CYP2B6, CYP2C9, CYP2D6 and rat CYP3A2, CYP2B1, CYP2C11, CYP2D1 through the cocktail approach using ultra-performance liquid chromatography tandem mass spectrometry. Typical probe substrates were used as follows-midazolam for CYP3A2/3A4, dextromethorphan for CYP2D1/2D6, tolbutamide for CYP2C9/2C11, and bupropion for CYP2B1/2B6. RESULTS: The results of this study showed that myricetin might not be a time-dependent inhibitor. Moreover, myricetin inhibited CYP3A4 in an uncompetitive way with an inhibition constant (Ki) value of 143.1 µM. It was also a noncompetitive inhibitor of CYP2C9 and CYP2D6 with Ki values of 31.12 and 53.44 µM and a competitive inhibitor of CYP2B1 with a Ki value of 69.70 µM, as well as a mixed inhibitor of CYP3A2, CYP2C11 and CYP2D1with Ki values of 37.57, 14.88 and 17.39 µM, respectively. CONCLUSIONS: In conclusion, this study indicates that myricetin inhibited CYP3A4/3A2, CYP2C9/2C11, CYP2D6/2D1 and CYP2B1 by various mechanisms with different Ki values. Given that our experiments are established in vitro, further in vivo work is needed to confirm the interaction between myricetin and CYP enzymes, thus providing better guidance for the safe clinical use of myricetin.

RESUMO

Objective: To explore the efficacy and safety of Yun's optimized pelvic floor training (OPFT) therapy for idiopathic moderate overactive bladder (OAB) with female sexual dysfunction (FSD) in young and middle-aged women. METHODS: Eighty 25-45 years old women with idiopathic moderate OAB companied by FSD were randomized into an experimental and a control group of equal number, the former treated by 6 weeks of Yun's OPFT therapy, followed by a 2-week washout period and then another 6 weeks of traditional pelvic floor muscle exercises (PFME), while the latter by 6 weeks of traditional PFME, followed by a 2-week washout period also and then another 6 weeks of Yun's OPFT. At 0, 6 and 14 weeks, we recorded the scores on overactive bladder symptoms (OABS), patient perception of bladder condition (PPBC), Urogenital Distress Inventory (UDI-6) and Incontinence Impact Questionnaire-7 (IIQ-7), pelvic floor muscle strength, voided volume (VV), average urinary flow rate (Qavg), maximum urinary flow rate (Qmax) and postvoid residual urine volume (PVR), female sexual function index (FSFI), sexual satisfaction of the male partners and adverse events, and compared the parameters obtained between the two groups of patients. RESULTS: Thirty-eight of the patients in the experimental group and 29 controls completed the experiment. There were no statistically significant differences in the baseline data between the two groups (P > 0.05). After 6 and 14 weeks of treatment, the effectiveness rate was decreased from 71% to 58% in the experimental group, but increased from 45% to 72% in the control. Significant improvement was achieved in the experimental group in the OABS, PPBC, UDI-6 and IIQ-7 scores, pelvic floor muscle strength, VV, Qavg, Qmax, FSFI and sexual satisfaction of the male partners at 6 weeks as compared with the baseline (P < 0.05), and even more significant at 14 weeks than at 6 (P < 0.05), and so was it in the control group in the PPBC and IIQ-7 scores, VV, Qmax and sexual satisfaction of the male partners at 6 weeks (P < 0.05), and more significant in the OABS, PPBC, UDI-6 and IIQ-7 scores, pelvic floor muscle strength, FSFI and sexual satisfaction of the male partners at 14 than at 6 weeks (P < 0.05). The patients of the experimental group showed remarkably more improvement than the controls in the OABS, PPBC, UDI-6 and IIQ-7 scores, pelvic floor muscle strength, FSFI and sexual satisfaction of the male partners at 6 weeks (P < 0.05), while the control group exhibited significantly better improved OABS, PPBC, UDI-6 and IIQ-7 scores, pelvic floor muscle strength, VV, Qmax, PVR and FSFI than the experimental group at 14 weeks (P < 0.05). No serious adverse reactions were observed during the treatment. CONCLUSIONS: Yun's OPFT therapy can improve the symptoms of moderate OAB with FSD in young and middle-aged women, with significantly better effects than traditional pelvic floor muscle exercises.

RESUMO

Antimicrobial peptides (AMPs) are small proteins showing broad-spectrum antimicrobial activity that have been known to be powerful agents against a variety of pathogens (bacteria, fungi and viruses). In this study, the effects of AMPs from Bacillus subtilis on Epinephelus coioides were examined. E. coioides were fed with diets containing AMPs (0, 100, 200, 400 or 800 mg/kg) for four weeks. Results showed that the levels of total protein (TP), albumin (ALB), alanine aminotransferase (ALT), aspartate aminotransferase (AST), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C) and blood glucose (GLU) and lipopolysaccharide (LPS) in the serum of E. coioides changed than those of the control group; compared to the control group, the levels of total antioxidant capacity (T-AOC), superoxide dismutase (SOD), catalase (CAT), malondialdehyde (MDA) and lysozyme (LZM) levels in E. coioides fed with different dosages AMP diets were also different; in addition, the mRNA expression of tumor necrosis factor alpha (TNF-α), interleukin-1-beta (IL-1ß), and heat shock protein 90 (Hsp90) in the tissues of E. coioides were measured, the three genes in the tissues examined were significantly upregulated. The results demonstrated that diets containing AMPs can enhance the antioxidant capacity and innate immune ability of E. coioides, indicating that AMPs might be a potential alternative to antibiotics in E. coioides.

RESUMO

OBJECTIVE: To analyze the factors influencing the therapeutic effect of "Shoulder Tri-needles therapy" in the treatment of shoulder-hand syndrome of stroke patients by using machine learning approach, so as to provide a feasibility for improving clinical efficacy. METHODS: A total of 586 stroke patients with shoulder-hand syndrome eligible for this study were involved in our machine learning experiments for classification of the influential factors. Their data including the age, gender, pulse condition, complexion, tongue quality, tongue coating, disease stage, body mass index (BMI), blood pressure, blood glucose, blood triglyceride, blood total cholesterol, smoking history, drinking history, and final outcomes were extracted from the medical record system (from Oct. of 2014 to Jan. of 2017 in the First Affiliated Hospital and Shenzhen Futian Hospital of Guangzhou University of Chinese Medicine). The single rule algorithm (1 R) was adopted to learn, followed by optimization with Repeated Incremental Pruning to Produce Error Reduction (RIPPER) algorithm, and C 5.0 decision tree algorithm. RESULTS: The accurate classification rates of 1 R, RIPPER and decision tree model were 87.37%(512/586), 95.90% (562/586), and 97.10% (569/586), respectively. The final outcomes of machine learning of this study showed that the disease stage (acute or recovery stage), complexion difference, tongue coating difference, blood pressure level, consumption of alcohol, BMI, and smoking habit were the most important factors influencing the therapeutic effect of "Shoulder Tri-needles" in the treatment of shoulder-hand syndrome of stroke patients. CONCLUSION: The disease stage, complexion and tongue identification, blood pressure level, alcohol drinking and smoking habits, and BMI are the principal factors affecting the therapeutic effect of "Shoulder Tri-needles therapy" in the treatment of shoulder-hand syndrome of stroke patients.

RESUMO

BACKGROUND/AIMS: Alzheimer disease (AD) is a common neurodegenerative disease that is characterized by the deposition of beta-amyloid peptide and formation of intracellular neurofibrillary tangles. Due to the failure of various clinical trials of novel drugs for AD, effective drugs for AD treatment are urgently required. METHODS: In this study, we used the classic APP/PS1 mouse model to explore the neuroprotective effects of a new compound, bajijiasu, and the mechanisms involved. Behavioral tests and western blotting were performed to assess the beneficial effects of bajijiasu in APP/PS1 mice. RESULTS: Morris water maze and Y-maze test results showed that oral administration of bajijiasu (35 mg/kg/day and 70 mg/kg/day) improved learning and memory abilities in APP/PS1 mice. Bajijiasu reduced ROS and MDA levels in both the hippocampus and cortex. Moreover, western blotting results showed that bajijiasu protected neurons from apoptosis, elevated the expression levels of neurotrophic factors, and alleviated endoplasmic reticulum stress in both the hippocampus and cortex. CONCLUSION: These results indicate that the mechanisms underlying the effects of bajijiasu on AD might be related to beta-amyloid-downstream pathologies, particularly endoplasmic reticulum stress.

RESUMO

AIMS: CYP2C19 is an important member of the cytochrome P450 enzyme superfamily. We recently identified 31 CYP2C19 alleles in the Han Chinese population. The aim of this study was to assess the catalytic activities of these allelic isoforms and their effects on the metabolism of fluoxetine in vitro. METHODS: The wild-type and 30 CYP2C19 variants were expressed in insect cells and each variant was characterized using fluoxetine as the substrate. Reactions were performed at 37°C with 20-1,000 µmol/L substrate for 30 min. By using ultra-high performance liquid chromatography-mass spectrometry to detect the products, the kinetic parameters Km, Vmax, and intrinsic clearance (Vmax/Km) of norfluoxetine were determined. RESULTS: Among the CYP2C19 variants tested, T130M showed similar intrinsic clearance (Vmax/Km) values with CYP2C19*1, while the intrinsic clearance values of other variants were significantly decreased (from 9.56 to 77.77%). In addition, CYP2C19*3 and *35FS could not be detected because they have no detectable enzyme activity. CONCLUSION: In China, the assessment of CYP2C19 variants in vitro offers valuable information relevant to the personalized medicine for CYP2C19-metabolized drug.

RESUMO

OBJECTIVE: To evaluate the effectiveness of the monotherapy of Cardura and the combination therapy of Cardura and Tolterodine L-Tartrate Tablets for II° ? benign prostate hyperplasia (BPH) with overactive bladder (OAB). METHODS: This study included 87 cases of BPH with OAB, with a disease course > or = 3 months, daily urination > or = 8 times, nocturnal urination > or = 2 times, urine volume < 200 ml per time, International Prostate Symptom Score (IPSS) > or = 8, OAB symptom score (OABS) > or = 3, quality of life score (QOL) > or = 3, post-void residual (PVR) < or = 100 ml, maximum urinary flow (Qmax) > or = 5 ml/s, prostate weight 25-50 g, and PSA < 4 microg/L. We randomized the patients to a monotherapy group (n = 44) and combination group (n = 43), the former treated with Cardura 4 mg qd, and the latter with Cardura 4 mg + Tolterodine L-Tartrate Tablets 4 mg qd, both for 8 weeks. Then we recorded the IPSS, OABS, Qmax, PVR, PSA, and adverse events. RESULTS: The baseline parameters showed no significant differences between the two groups (P > 0.05). In comparison with the baseline, both the monotherapy group and the combination therapy group showed significant decreased in the IPSS (16.50 +/- 4.27 vs 13.68 +/- 3.69 and 15.51 +/- 3.80 vs 11.49 +/- 2.75), urine storage symptom score (10.48 +/- 2.75 vs 7.98 +/- 2.34 and 9.47 +/- 2.31 vs 5.74 +/- 1.66), OABS (8.55 +/- 2.69 vs 6.32 +/- 1.97 and 8.21 +/- 2.55 vs 4.44 +/- 1.62), urgent micturition score (4.25 +/- 1.06 vs 3.23 +/- 0.99 and 4.07 +/- 0.83 vs 2.26 +/- 1.05), QOL (5.36 +/- 0.72 vs 3.43 +/- 0.66 and 5.07 +/- 0.86 vs 2.37 +/- 0.76) and PVR ([44.55 +/- 22.39] vs [38.30 +/- 20.20] ml and [36.19 +/- 21.21] vs [24.98 +/- 17.60] ml) (P < 0.01). All the six parameters were significantly more improved in the combination therapy group than in the monotherapy group (P < 0.01), but there were no remarkable differences between the groups in Qmax and voiding symptom score (P > 0.05). Neither group exhibited significant changes in the PSA level and prostate weight after treatment as compared with the baseline (P > 0.05). No acute urinary retention and other severe adverse reactions were observed during the medication. CONCLUSION: Both Cardura monotherapy and the combination therapy of Cardura + Tolterodine L-Tartrate Tablets can improve II ? BPH with OAB, and the latter has an even better efficacy than the former.

RESUMO

OBJECTIVE: To explore the clinical features and related factors of sexual dysfunctions in male patients with pituitary adenomas. METHODS: The questionnaires of sexual functions were collected from 86 male patients with pituitary adenomas. We examined the clinical features of sexual dysfunctions and analyzed the correlations between sexual behaviors and age, tumor type, invasiveness, tumor size, serum levels of prolactin (PRL) and testosterone. RESULTS: The incidence of sexual dysfunctions was 80.2% (69/86). Sexual dysfunctions were found in 84.6% (66/78) of the patients with functioning pituitary adenomas and 37.5% (3/8) of those with non-functioning pituitary adenoma respectively. In the PRL group, the incidence of erectile dysfunctions was 92.1% (35/38) and it was higher than those in the FSH (follicle-stimulating hormone) and GH (growth hormone) groups (P < 0.05). In the FSH group, the incidence of reduced sexual desire was 78.3% (18/23). In the GH group, the incidence of erectile dysfunctions was 70.6% (12/17) and the incidence of reduced sexual desire or ejaculation dysfunction was lower than that of the PRL/FSH group (P < 0.05). CONCLUSION: The incidence of sexual dysfunctions is quite high in males with pituitary adenomas, especially for those with functioning pituitary adenomas. The clinical features of sexual dysfunctions vary in different types of functioning pituitary adenoma. The incidence of erectile dysfunctions is the highest in the PRL group. Pathological type of pituitary tumors is a major risk factor of sexual dysfunctions.

RESUMO

OBJECTIVE: To improve the treatment of pyonephrosis with upper urinary tract calculi (UTC). METHODS: A total of 49 UTC patients with pyonephrosis were selected at our hospital during May 2004 to February 2010. Among them, 22 cases were treated with transurethral ureteroscope lithotripsy followed by tube internal drainage while another 27 cases underwent percutaneous nephrolithotomy. RESULTS: No such complications as septicemia and septic shock occurred during the first stage of external and internal drainage. The bacteremic symptoms of chill or fever occurred in 3 cases during the second stage of percutaneous nephrolithotomy and pyelolithotomy/ureterolithotomy (11.1%). There were 3 cases of nephrectomy. A follow-up period of 3 months to 5.5 years showed that all 33 cases had a varying degree of recovered renal functions. And there was no nephrectomy. CONCLUSION: The keys to a successful surgical treatment of pyonephrosis with upper urinary tract calculi are early diagnosis, timely drainage and relief of obstruction. Ureteroscopic lithotripsy, double-J placement and percutaneous nephrostomy drainage are excellent for relieving obstruction. As a safe procedure with minor complications, it creates proper conditions for a second stage operation.
