“Background: Galectin-3 (Gal-3) shows the ability of survival prediction in heart failure (HF) patients. However, Gal-3 is strongly associated with serum markers of cardiac extracellular matrix (ECM) turnover. The aim of this study is to compare the impact of Gal-3 and serum markers of cardiac ECM turnover on prognostic prediction of chronic systolic HF patients. Methods: Serum Gal-3, brain natriuretic peptide (BNP), extracellular matrix including type I and III aminoterminal propeptide of procollagen (PINP and PIIINP), matrix metalloproteinase-2,

9 (MMP-2, 9), and tissue inhibitor of metalloproteinase-1 (TIMP-1) were analyzed. Cox regression analysis was used for survival analysis. Results: A total of 105 (81 male) patients were enrolled. During 980 +/- 346 days follow-up, 17 patients died and 36 episodes of HF selleck admission happened. Mortality of these patients

was significantly associated with the log PIIINP (beta= 15.380; P=0.042), log TIMP-1(beta= 44.530; P=0.003), Pim inhibitor log MMP-2 (beta= 554.336; P smaller than 0.001), log BNP (beta= 28.273; P=0.034). Log Gal-3 (beta= 7.484; P=0.066) is borderline associated with mortality. Mortality or first HF admission of these patients was significantly associated with the log TIMP-1(beta= 16.496; P=0.006), log MMP-2 (beta= 221.864; P smaller than 0.001), log BNP (beta= 5.999; P=0.034). Log Gal-3 (beta= 4.486; P=0.095) only showed borderline significance. In several models adjusting clinical parameters, log MMP-2 was significantly associated

with clinical outcome. In contrast, log Gal-3 was not. Conclusion: The prognostic strength of MMP-2 to clinical outcome prediction in HF patients is stronger than Gal-3.”
“Objective-The present studies aimed a elucidating the role of prostaglandin E-2 receptor subtype 3 (E-prostanoid [EP] 3) in regulating blood pressure.\n\nMethods and Results-Mice bearing a genetic disruption of the EP3 gene (EP3-/-) exhibited reduced baseline mean arterial pressure monitored by both tail-cuff and carotid arterial catheterization. The pressor responses induced find more by EP3 agonists M&B28767 and sulprostone were markedly attenuated in EP3(-/-) mice, whereas the reduction of blood pressure induced by prostaglandin E-2 was comparable in both genotypes. Vasopressor effect of acme or chronic infusion of angiotensin II (Ang II) was attenuated in EP3(-/-) mice. Ang II-induced vasoconstriction in mesenteric arteries decreased in EP3(-/-) group. In mesenteric arteries from wild-type mice, Ang II-induced vasoconstriction was inhibited by EP3 selective antagonist DG-041 or L798106. The expression of Arhgef-1 is attenuated in EP3 deficient mesenteric arteries. EP3 antagonist DG-041 diminished Ang II-induced phosphorylation of myosin light chain 20 and myosin phosphatase target subunit 1 in isolated mesenteric arteries.

These two possibilities could be distinguished by the use of pure preparations of glucose isomers. In the laboratory, selected eukaryotes,

bacteria, and archaea consumed only D-glucose, not L-glucose, while permanganate oxidized both isomers. On Mars, selective consumption of either D- or L-glucose would constitute evidence for biological activity.”
“The thick peptidoglycan layers of Gram-positive bacteria are connected to polyanionic glycopolymers GSK461364 datasheet called wall teichoic acids (WTA). Pathogens such as Staphylococcus aureus, Listeria monocytogenes, or Enterococcus faecalis produce WTA with diverse, usually strain-specific structure. Extensive studies on S. aureus WTA mutants revealed important functions of WTA in cell division, growth, morphogenesis, resistance

to antimicrobials, and interaction with host or phages. While most of the S. aureus WTA-biosynthetic genes have been identified it remained unclear for long how and why S. aureus glycosylates WTA with alpha or beta-linked N-acetylglucosamine (GlcNAc). Only recently the discovery of two WTA glycosyltransferases, TarM and TarS, yielded fundamental insights into the roles of S. aureus WTA glycosylation. Mutants lacking WTA GlcNAc are resistant towards most of the S. aureus phages and, surprisingly, TarS-mediated WTA beta-O-GlcNAc modification is essential for beta-lactam learn more resistance in methicillin-resistant S. aureus. Notably, S. aureus WTA GlcNAc residues are major antigens and activate the complement system contributing to opsonophagocytosis. WTA glycosylation with a variety of sugars and corresponding glycosyltransferases were also identified in other Gram-positive bacteria, which paves the way for detailed investigations on the diverse roles of WTA modification with sugar residues.

“Sapindus mukorossi Gaerten., as a rich source of saponins, is an important agricultural economic tree in tropical and subtropical regions. Its fruit pericarp has a high content of triterpenoid 432 saponins of high surface activity and important biological

activities. Thus the current work adopted a two-stage foam fractionation technology to separate the saponins from the pericarp. A spiral internal component and elevated temperature were utilized to improve enrichment ratio. Using this technology, the enrichment ratio of the sapindus saponins reached 133.4 with a recovery of over 36.4% and the separated saponins had a high purity of 90.3%. The product was analyzed by FTIR and HPLC-MS to determine its ingredients, including plentiful triterpenoid saponins and bits of sesquiterpene glucosides. The subsequent bioactivity analysis made sure that the product had moderate but long-term antimicrobial activity. Therefore the current work had industrial implication in producing high-purity saponins for food, cosmetics and even pharmaceutical fields.

In addition, exogenous stimulation consistently evoked this neocortical-to-hippocampal sequence of activation. Finally, parahippocampal lesions that disrupted functional connections between the neocortex and hippocampus effectively disrupted the transmission of both spontaneous and evoked neocortical activity to the hippocampus. These findings suggest that sleep-related motor activity

contributes to the development of neocortical and hippocampal circuits and provides a foundation on which coordinated activity between these two forebrain structures develops.”
“Background: Pediatric obesity is a growing problem affecting the health of our youth. We sought to identify the barriers to pediatric bariatric referral at a tertiary referral #4 randurls[1|1|,|CHEM1|]# center.\n\nMethods: We performed a Survey of pediatricians and family practitioners at a single institution to assess their perspectives oil pediatric obesity.\n\nResults: A total of 61 physicians completed the survey (response rate 46%). All believed pediatric obesity is a major problem, and 82.0% noted an increase in the incidence during

a mean period of 15 years (range URMC-099 3-25). Of the 61 physicians. 88.5% used nonoperative weight loss techniques, with only 1.8% reporting satisfactory results. However, 42.6% had referred a patient (adult or pediatric) for a bariatric procedure. of whom 84.6% were satisfied with the operative outcomes. Despite the high satisfaction with bariatric procedures, 88.5% would be unlikely

or would never refer a child for a bariatric procedure, and 44.3% would be somewhat or very likely to refer all adolescent.\n\nConclusion: physicians caring for children recognize the growing problem of childhood and adolescent obesity. Despite the poor outcomes with nonoperative methods and the high satisfaction with the outcomes of bariatric procedures, physicians are still reluctant to refer children and adolescents for surgical weight loss procedures.

“Sinonasal aspergillosis is an uncommon, yet debilitating and often frustrating condition to treat in dogs despite years of research AZD7762 clinical trial evaluating pathogenesis, diagnosis and treatment. The disease is most commonly caused by non-invasive fungal infection, thought to be secondary to altered innate and/or adaptive immune responses. Attempts to confirm this have however failed. A variety of conflicting opinions regarding the diagnosis and treatment of sinonasal aspergillosis exist. Often the use of a particular treatment protocol is based upon personal or regional preference. Evaluation of the veterinary literature demonstrates that the evidence base in support of individual treatment recommendations is weak.

For the continuous grazing system, sheep grazed the same plots each year, and for the alternating system, grazing and hay making were

alternated annually between two adjacent plots. In July, August, and September 2009 and 2010, feed intake and live weight of sheep were Entinostat datasheet determined. The GS did not affect dOM (P=0.101), OMI (P=0.381), and LWG of sheep (P=0.701). Across both GS LWG decreased from 98 g . d(-1) for GI1 to 62 g . d(-1) for GI6 (P smaller than 0.001; R-2=0.42). There were no interactions between GS and GI for all measured parameters (P bigger than = 0.061), indicating that alternating grazing did not compensate for negative effects of heavy grazing even after 4 yr of grassland use. In summary, our study showed that irrespective of GI, alternating grassland use does not improve dOM, OMI, and hence, LWG of sheep. However, it Elafibranor might enhance revenues and ecological sustainability in the long term when compared to the common practice of continuous grazing at very high stocking rates.”
“Assortative mating, an ubiquitous form of nonrandom mating, strongly impacts Darwinian fitness and can drive biological diversification. Despite its ecological and evolutionary importance, the behavioural processes underlying assortative mating are often unknown, and in particular, mechanisms not involving mate choice

have been largely ignored so far. Here, we propose that assortative mating can arise from prudent habitat choice’, a general mechanism that acts under natural selection, and that it can occur despite a complete mixing of phenotypes. We show that in the

cichlid Eretmodus cyanostictus size-assortative mating ensues, because individuals of weaker competitive ability see more ignore high-quality but strongly competed habitat patches. Previous studies showed that in E.cyanostictus, size-based mate preferences are absent. By field and laboratory experiments, here we showed that (i) habitat quality and body size are correlated in this species; (ii) territories with more stone cover are preferred by both sexes in the absence of competition; and (iii) smaller fish prudently occupy vacant territories of worse quality than do larger fish. Prudent habitat choice is likely to be a widespread mechanism of assortative mating, as both preferences for and dominance-based access to high-quality habitats are generic phenomena in animals.”
“INTRODUCTION: Activation of renal sympathetic nerves is associated with the development of hypertension. Catheter-based renal sympathetic denervation with radiofrequency energy ablation is a new promising treatment option for resistant hypertension. We here report the first Danish experiences and results with this technique.\n\nMATERIAL AND METHODS: Nine patients with resistant hypertension and a day-time 24-hour ambulatory blood pressure (BP) of 152/89 mmHg +/- 10/10 (standard deviation) mmHg despite treatment with 5.4 +/- 1.

These devices allow the performing of movements that cannot be carried out by persons with amputated limbs. The state of the art in the development of MCSs is based on the use of individual principal component analysis (iPCA) as a stage of pre-processing of the classifiers. The iPCA pre-processing implies an optimization stage which has not yet been deeply explored.\n\nMethods: The present study considers two factors in the iPCA stage: namely A (the fitness function), and B (the search algorithm). The A factor comprises two levels, namely A(1) (the classification error) and A(2) (the correlation factor). Otherwise, the B factor has four levels, specifically

B-1 (the Sequential Forward Selection, SFS), B-2 (the Sequential Floating Forward Selection, SFFS), B-3 (Artificial Staurosporine Bee Colony, ABC), and B-4 (Particle Swarm Optimization, PSO). This work evaluates the incidence of each one of the eight possible combinations between A and B factors over the classification error of the MCS.\n\nResults: A two factor ANOVA was performed on the computed classification errors and determined that: (1) the interactive effects over the classification error are not significative (F-0.01,F-3,F-72 = 4.0659 > f(AB) = 0.09), (2) the levels of factor A have

significative effects on the classification error (F-0.02,F-1,F-72 click here = 5.0162 < f(A) = 6.56), and (3) the levels of factor B over the classification error are not significative (F-0.01,F-3,F-72 PU-H71 manufacturer = 4.0659 > f(B) = 0.08).\n\nConclusions: Considering the classification performance we found a superiority of using the factor A(2) in combination with any of the levels of factor B. With respect to the time performance the analysis suggests that the PSO algorithm is at least 14 percent better than its best competitor. The latter behavior has been observed for a particular configuration

set of parameters in the search algorithms. Future works will investigate the effect of these parameters in the classification performance, such as length of the reduced size vector, number of particles and bees used during optimal search, the cognitive parameters in the PSO algorithm as well as the limit of cycles to improve a solution in the ABC algorithm.”
“This paper presents a child swing motion modelled as the variable length of pendulum without damping effect. We have discussed the mathematical model of child swing motion and numerical simulation by using multiple scales method. It is shown that the physical behavior of child swing motion has resemblance with the physical nature of harmonic motion of simple pendulum, for the value of angular frequency less than and equal to two of child swing motion. MATLAB 7.0 is used for phase plane analysis in justification of theoretical results.”
“Purpose: The process of breast cancer follow-up has psychosocial benefits for patients, notably reassurance, although attending hospital appointments can increase anxiety.

The TZD ring was replaced with: a mercaptoacetic acid group [[[(3,5-dichlorophenyl)amino]carbonyl]thio]acetic acid, DCTA; a methylated TZD ring [3-(3,5-dichlorophenyl)-5-methyl-2,4-thiazolidinedione, DPMT]; and isomeric thiazolidinone rings [3-(3,5-dichlorophenyl)-2- and 3-(3,5-dichlorophenyl)-4-thiazolidinone,

123 2-DCTD and 4-DCTD, respectively]. The following phenyl ring-modified analogs were also tested: 3-phenyl-, 3-(4-chlorophenyl)-, 3-(3,5-dimethylphenyl)- and 3-[3,5-bis(trifluoromethyl)phenyl]-2,4-thiazolidinedione (PTZD, CPTD, DMPT and DFMPT, respectively). Toxicity was assessed in male Fischer 344 rats 24 h after administration of the compounds. In the TZD series only DPMT produced liver damage, as evidenced by elevated serum selleck alanine aminotransferase (ALT) activities at 0.6 and 1.0 mmol kg-1 (298.6 +/- 176.1 and 327.3 +/- 102.9 Sigma-Frankel units ml-1, respectively) vs corn oil controls (36.0 +/- 11.3) and morphological changes in liver GW4869 research buy sections. Among the phenyl analogs, hepatotoxicity was observed in rats administered PTZD, CPTD and DMPT; with ALT values

of 1196.2 +/- 133.6, 1622.5 +/- 218.5 and 2071.9 +/- 217.8, respectively (1.0 mmol kg(-1) doses). Morphological examination revealed severe hepatic necrosis in these animals. Our results suggest that hepatotoxicity of these compounds is critically dependent on the presence of a TZD ring and also the phenyl substituents. Copyright (C) 2011 John Wiley & Sons, Ltd.”
“The targets of broadly cross-neutralizing (BCN) antibodies are of great interest in the HIV vaccine field. We have identified a subtype C HIV-1-superinfected individual, CAP256, with high-level BCN activity, and characterized the antibody specificity mediating breadth. CAP256 developed potent BCN activity peaking at 3 years postinfection, neutralizing 32 (76%) of 42 heterologous viruses, with titers of antibodies against some viruses exceeding 1:10,000. CAP256 showed a subtype bias, preferentially

neutralizing subtype C and A viruses over subtype B viruses. CAP256 BCN serum targeted a quaternary epitope which included the V1V2 region. Further mapping identified residues F159, N160, L165, R166, D167, K169, and K171 (forming the FN/LRD-K-K motif) in the V2 region as crucial to the CAP256 epitope. However, YAP-TEAD Inhibitor 1 in vivo the fine specificity of the BCN response varied over time and, while consistently dependent on R166 and K169, became gradually less dependent on D167 and K171, possibly contributing to the incremental increase in breadth over 4 years. The presence of an intact FN/LRD-K-K motif in heterologous viruses was associated with sensitivity, although the length of the adjacent V1 loop modulated the degree of sensitivity, with a shorter V1 region significantly associated with higher titers. Repair of the FN/LRD-K-K motif in resistant heterologous viruses conferred sensitivity, with titers sometimes exceeding 1: 10,000.

These particles self-organize into hierarchically ordered supramolecular structures in the bulk For example, the Janus particle with isobutyl groups on one

POSS and carboxylic learn more groups on the other self-assembles into a bilayered structure with head-to-head, tail-to-tail arrangements of each particle, which further organize into a three-dimensional orthorhombic lattice. While the ordered structure in the layers was lost upon 123 heating via a first-order transition, the bilayered structure persisted throughout This study provides a model system of well-defined molecular Janus particles for the general understanding of their self-assembly and hierarchical structure formation in the condensed state.”
“Purpose: To develop a technique to monitor the dose rate in the urethra during permanent implant brachytherapy using a linear MOSFET array, with sufficient accuracy and without significantly extending the implantation time.\n\nMethods and Materials: Phantom measurements were performed to determine the optimal conditions for clinical measurements. In vivo

measurements were performed in 5 patients during the (125)I brachytherapy implant procedure. To evaluate if the urethra dose obtained in the operating room with the ultrasound transducer in the rectum and the patient in treatment position is a reference for the total accumulated dose; additional measurements were performed after the implantation procedure, in the recovery room.\n\nResults: click here In vivo measurements during Selleck Buparlisib and after the implantation procedure agree very well, illustrating that the ultrasound transducer in the rectum and patient positioning do not influence the measured dose in the urethra. In vivo

dose values obtained during the implantation are therefore representative for the total accumulated dose in the urethra. In 5 patients, the dose rates during and after the implantation were below the maximum dose rate of the urethra, using the planned seed distribution.\n\nConclusion: In vivo dosimetry during the implantation, using a MOSFET array, is a feasible technique to evaluate the dose in the urethra during the implantation of (125)I seeds for prostate brachytherapy.

“Serotonergic neurons in the median raphe nucleus (MnR) are stimulated by alpha(1)-adrenergic agonists and inhibited by alpha(2) agonists. This study investigated the participation of MnR alpha(2)-adrenergic receptors in the control of anxiety-like behavior and feeding as an attempt to establish a functional association between these behaviors. The alpha(2)-adrenergic agonist clonidine (CLON) was injected into the MnR (0, 0.2, 2, 6, 20 nmol), into the pontine nucleus (Pn) or into the mesencephalic reticular formation (mRt) (0.2, 20 nmol) of free-feeding rats. The animals were exposed to the elevated plus-maze to evaluate spatial-temporal and ethological variables.

“The orphan receptor LRH-1 and the oxysterol receptors LXR alpha and LXR beta are established transcriptional regulators of lipid metabolism that appear to control inflammatory processes. Here, we investigate the anti-inflammatory actions of these nuclear receptors in the hepatic acute phase response (APR). We report that selective synthetic agonists induce SUMOylation-dependent recruitment of either LRH-1 or LXR to hepatic APR promoters

and prevent the clearance of the N-CoR corepressor complex upon cytokine stimulation. Investigations of the APR in vivo, using LXR knockout mice, indicate that the anti-inflammatory actions of LXR agonists are triggered selectively by the LXR beta subtype. We further find that hepatic APR responses MK0683 in small ubiquitin-like modifier-1 (SUMO-1) knockout mice

are increased, which is due in part to diminished LRH-1 action at APR promoters. Finally, we provide evidence that the metabolically important coregulator GPS2 functions as a hitherto unrecognized transrepression mediator of interactions between SUMOylated nuclear receptors and the N-CoR corepressor complex. Our study extends the knowledge of anti-inflammatory mechanisms and pathways directed by metabolic nuclear LY2606368 receptor-corepressor networks to the control of the hepatic APR, and implies alternative pharmacological strategies for the treatment of human metabolic diseases associated with inflammation.”
“Peroxisome proliferator activated receptor-gamma 2 (PPARG2) is a nuclear hormone receptor of ligand-dependent transcription factor involved in adipogenesis and a molecular target of the insulin sensitizers thiazolidinediones. We addressed the question of whether the 3 variants (-1279G/A, Pro12Ala, and His478His) in the PPARG2 gene are associated with type

2 diabetes mellitus and its related traits in a South Indian population. The study subjects (1000 type 2 diabetes mellitus and 1000 normal glucose-tolerant subjects) were chosen randomly from the Chennai Urban Rural Epidemiology GW4869 Study, an ongoing population-based study in southern India. The variants were screened by single-stranded conformational variant, direct sequencing, and restriction fragment length polymorphism. Linkage disequilibrium was estimated from the estimates of haplotypic frequencies. The -1279G/A, Pro12Ala, and His478His variants of the PPARG2 gene were not associated with type 2 diabetes mellitus. However, the 2-loci analyses showed that, in the presence of Pro/Pro genotype of the Pro12Ala variant, the -1279G/A promoter variant showed increased susceptibility to type 2 diabetes mellitus (odds ratio, 2.092; 95% confidence interval, 1.22-3.59; P = .008), whereas in the presence of 12Ala allele, the -1279G/A showed a protective effect against type 2 diabetes mellitus (odds ratio, 0.270; 95% confidence interval, 0.15-0.

Mixing a single-site acting fungicide with a multi-site acting fungicide delayed the emergence of resistance to the single-site component. Combining the findings with previous work on the selection phase will enable us to develop more efficient anti-resistance strategies.”
“Formal evaluation of hospital performance in specific

types of care is becoming an indispensable tool for quality assurance in the health care system. When the prime concern lies in reducing the risk of a cause-specific event, we propose to evaluate performance in terms of an average excess cumulative incidence, referring to the center’s observed patient mix. Its intuitive interpretation helps give meaning to the evaluation results and facilitates the determination

of important benchmarks for hospital performance. We apply it to the evaluation of cerebrovascular learn more deaths after stroke in Swedish stroke centers, using data from Riksstroke, the Swedish stroke registry. Copyright (c) 2015 John Wiley & Sons, Ltd.”
“Experimental evidence suggests that the healing of diabetic foot ulcers is affected by psychosocial factors such as distress. We examined this proposal in a prospective study, in which we considered the role of psychological distress and coping style in the healing of diabetic foot Z-DEVD-FMK supplier ulcers over a 24 week period. We also explored the role of salivary cortisol and matrix metalloproteinases (MMPs) as potential mechanisms.\n\nFor this prospective observational study we recruited 93 (68 men; mean age 60 years) patients with neuropathic or neuroischaemic diabetic foot ulcers from specialist AS1842856 solubility dmso podiatry clinics in secondary care. Clinical and demographic determinants of healing, psychological distress, coping, salivary cortisol and both MMP2 and MMP9 were assessed at baseline. Ulcers were assessed at baseline and at 6, 12 and 24 weeks post-baseline. The primary outcome was ulcer status at 24 weeks, i.e. healed vs not healed.\n\nAfter controlling

for clinical and demographic determinants of healing, ulcer healing at 24 weeks was predicted by confrontation coping, but not by depression or anxiety. Patients with unhealed ulcers exhibited greater confrontation coping (model including depression: OR 0.809, 95% CI 0.704-0.929, p = 0.003; model including anxiety: OR 0.810, 95% CI 0.704-0.930, p = 0.003). However, change in ulcer size over the observation period was associated with depression only (p = 0.04, d = 0.31). Healed ulcers by 24 weeks were also associated with lower evening cortisol, higher precursor MMP2 and a greater cortisol awakening response.\n\nConfrontation coping and depression predict ulcer healing. Our preliminary enquiry into biological mechanisms suggests that cortisol and precursor MMP2 may underlie these relationships.

Mitochondria make use of molecular machinery that couples these organelles to microtubule-based transport via kinesin and dynein motors, facilitating the required long-range movements. These motors in turn are associated with a variety of adaptor proteins allowing additional regulation of the complex dynamics demonstrated by these organelles. Over recent years, a number of new motor and adaptor proteins have been added to a growing list of components implicated in mitochondrial trafficking and distribution.

Yet, there are major questions that remain to be addressed about the regulation of mitochondrial transport complexes. One of the core components of this machinery, the mitochondrial Rho Selleckchem Galardin GTPases Miro1 (mitochondrial Rho 1) and Miro2

PLX3397 have received special attention due to their Ca2+ -sensing and GTPase abilities, marking Miro an exceptional candidate for co-ordinating mitochondrial dynamics and intracellular signalling pathways. In the present paper, we discuss the wealth of literature regarding Miro-mediated mitochondrial transport in neurons and recently highlighted involvement of Miro proteins in mitochondrial turnover, emerging as a key process affected in neurodegeneration.”
“A liquid chromatography tandem mass spectrometry (LC-MS/MS) method was developed for the simultaneous AZD6094 research buy determination of baicalin, wogonoside, baicalein, wogonin, oroxylin A and chrysin in rat plasma, using naringin as an internal standard. After acidifying with HCl, plasma samples were pretreated by liquid-liquid extraction with acetone. Chromatographic separation was accomplished on a Hypersil Gold-C-18 analytical column (2.1

x 150 mm, 5 mu m) utilizing a gradient elution profile and a mobile phase consisting of (A) 0.1% formic acid in water and (B) acetonitrile. Detection was performed by multiple reaction monitoring (MRM) mode using electrospray ionization in the positive ion mode. All analytes showed good linearity over the investigated concentration range (r > 0.9900). The lower limit of quantification was 0.5 ng/ml for baicalin, wogonoside, wogonin and oroxylin A, and 1.0 ng/ml for baicalein and chrysin. Intra-day and inter-day precisions (RSD%) were less than 15% and accuracy (RE%) ranged from -6.7% to 5.8%. The validated method was successfully applied to investigate the pharmacokinetics of the major flavonoids of Radix scutellariae extract after oral administration to rats. (C) 2012 Elsevier B.V.
