    Two groups of patients with chronic plaque psoriasis were topically treated either with 10% cyclosporin in a jelly base or with 5% cyclosporin in an ointment base under occlusion. We found that cyclosporin penetrates into the lower epidermis and the dermis, when it is applied under occlusion. Obviously, the target cells are neutrophil granulocytes, since they decrease in number under cyclosporin, whereas the other inflammatory cells as well as the epidermal proliferation remain unchanged. In contrast to systemic application of cyclosporin, we did not observe any clinical differences between plaques treated with cyclosporin and those treated with placebo. PMID:2202163

    In order to minimize the impact of systemic toxicity of drugs in the treatment of local acute and chronic inflammatory reactions, the achievement of reliable and efficient delivery of therapeutics in/through the skin is highly recommended. While the use of nanoparticles is now an established practice for drug intravenous targeted delivery, their transdermal penetration is still poorly understood and this important administration route remains almost unexplored. In the present study, we have synthesized magnetic (iron oxide) nanoparticles (MNP) coated with an amphiphilic polymer, developed a water-in-oil emulsion formulation for their topical administration and compared the skin penetration routes with the same nanoparticles deposited as a colloidal suspension. Transmission and scanning electron microscopies provided ultrastructural evidence that the amphiphilic nanoparticles (PMNP) cream formulation allowed the efficient penetration through all the skin layers with a controllable kinetics compared to suspension formulation. In addition to the preferential follicular pathway, also the intracellular and intercellular routes were involved. PMNP that crossed all skin layers were quantified by inductively coupled plasma mass spectrometry. The obtained data suggests that combining PMNP amphiphilic character with cream formulation improves the intradermal penetration of nanoparticles. While PMNP administration in living mice via aqueous suspension resulted in preferential nanoparticle capture by phagocytes and migration to draining lymph nodes, cream formulation favored uptake by all the analyzed dermis cell types, including hematopoietic and non-hematopoietic. Unlike aqueous suspension, cream formulation also favored the maintenance of nanoparticles in the dermal architecture avoiding their dispersion and migration to draining lymph nodes via afferent lymphatics.

    Extracts of Kaempferia parviflora (KP) were formulated in solid lipid nanoparticles (SLNs) in order to enhance their transdermal permeability. The KP extracts were entrapped within SLNs by adding them to a melted mixture of oils, surfactants and PEGylating agents and subsequently forming an oil-in-water microemulsion at an elevated temperature. Cooling of this microemulsion resulted in the formation of SLNs. The formulation with the optimum properties was composed of stearyl alcohol as the nanoparticle matrix and Tocopheryl Polyethylene Glycol Succinate (TPGS) as the surfactant. Particle sizes of 82-108 nm were obtained with entrapment efficiencies as high as 87%. The release of the flavonoids from the SLN matrix was measured after suspending them in a Phosphate Buffered Saline (PBS)/Tween 80 solution and demonstrated biphasic patterns. Permeability studies using a skin model composed of human-derived epidermal keratinocytes were conducted in which a topically applied KP extract-loaded SLN was compared to a KP-hydroxypropyl methylcellulose/Tween 80 gel formulation containing KP extract. The amount of total KP flavonoids in the SLNs and gel that had permeated through the skin after 25 hours (95.57 +/- 9.08 and 81.04 +/- 5.82 g, respectively) were found to be significantly different (P < 0.05). In addition, the flux values of three of the flavonoids were greater when incorporated in SLNs. PMID:20055101

    There has been much debate and controversy about the safety and efficacy of the topical use of tranexamic acid in primary total knee arthroplasty (TKA). The purpose of this study was to perform a meta-analysis to evaluate whether there is less blood loss and lower rates of transfusion after topical tranexamic acid administration in primary TKA. A systematic review of the electronic databases PubMed, CENTRAL, Web of Science, and Embase was undertaken. All randomized, controlled trials and prospective cohort studies evaluating the effectiveness of topical tranexamic acid during primary TKA were included. The focus of the analysis was on the outcomes of blood loss results, transfusion rate, and thromboembolic complications. Subgroup analysis was performed when possible. Of 387 studies identified, 16 comprising 1421 patients (1481 knees) were eligible for data extraction and meta-analysis. This study indicated that when compared with the control group, topical application of tranexamic acid significantly reduced total drain output (mean difference, -227.20; 95% confidence interval, -347.11 to -107.30; Pdeep venous thrombosis or pulmonary embolism due to tranexamic acid administration. Topical tranexamic acid was effective for reducing postoperative blood loss and transfusion requirements without increasing the prevalence of thromboembolic complications. PMID:26558665

    Chinese Holstein, bred by mating the Holstein-Friesian to Chinese Yellow Cattle, is a major dairy cattle breed in China. Eprinomectin is widely used in the treatment of nematode and ectoparasite infections in lactating cattle. The pharmacokinetics of eprinomectin in the plasma and milk were determined in Chinese Holstein cows following topical (at 0.5 mg kg(-1)) or oral (at 0.2 mg kg(-1)) administration. For topical administration, the concentrations of eprinomectin in plasma reached peak values (C(max)) of 16.16 ± 6.02 ng ml(-1) at 3.20 ± 1.30 days (T(max)). In milk, the C(max) values of 2.28 ± 0.85 ng ml(-1) were obtained at 3.48 ± 0.65 days. The MRT values were 5.00 ± 0.96 days for plasma and 4.65 ± 0.60 days for milk. The AUC values were 91.00 ± 25.32 ng d ml(-1) for plasma and 10.53 ± 1.55 ng d ml(-1) for milk. The ratio of AUC milk/plasma was 0.124 ± 0.041. Significant differences were found in C(max) and AUC of eprinomectin in plasma between Chinese Holstein and Prim Holstein following topical administration. It was probably due to the lower storage of body fat in Chinese Holstein than in Prim Holstein. For oral administration, the concentrations of eprinomectin reach peak values of 30.02 ± 5.73 ng ml(-1) at 1.60 ± 0.55 days in plasma and 3.14 ± 0.88 ng ml(-1) at 1.40 ± 0.27 days in milk. The MRT values for plasma and milk were 3.00 ± 0.46 and 3.18 ± 0.55 days, respectively. The AUC values were 98.46 ± 24.75 ng d ml(-1) for plasma and 10.42 ± 4.22 ng d ml(-1) for milk. The ratio of AUC milk/plasma was 0.104 ± 0.022. Compared with the topical administration, a significantly shorter MRT of eprinomectin in plasma was obtained following oral administration, which would shorten residue time of this compound in faeces and reduce its ecotoxicological effect. The low exposure of eprinomectin in milk would favor the use of eprinomectin in lactating Chinese Holstein for topical or oral administration. PMID:20851527

  12. Prevention of photocarcinogenesis by topical administration of pure epigallocatechin gallate isolated from green tea

    International Nuclear Information System (INIS)

    Topical application of purified (-)-epigallocatechin-3-gallate (EGCG), a polyphenolic antioxidant isolated from green tea, inhibited photocarcinogenesis in BALB/cAnNHsd mice with no visible toxicity. Mice were treated with 0, 10, or 50 mg of EGCG in 200 microliters of acetone three times weekly for three weeks before ultraviolet (UV) treatments began and throughout the experiment. UV radiation consisted of five 30-minute exposures per week to banks of six FS40 Westinghouse sunlamps for 25 weeks. In the photocarcinogenesis study, mice received a total dose of approximately 2.1 X 10(6) J/m2. Skin cancer incidence in UV-irradiated mice was 96% at 28 weeks after the first UV treatment; EGCG at 10 or 50 mg reduced this incidence to 62% and 39%, respectively. UV-induced immunosuppression, assessed by the inability of UVB-irradiated mice to reject a syngeneic antigenic tumor, was not influenced by topical EGCG. Oral administration of 0, 100, or 500 mg of pure EGCG per liter of drinking water (approximately 0, 0.56, or 2.8 mg/day, respectively) did not decrease UV-induced skin tumor incidence, rate of primary tumor growth, or inability to reject antigenic tumors. Thus induction of skin tumors by UV radiation was significantly reduced by topical, but not by oral, administration of purified EGCG through a mechanism distinct from inhibition of photoimmunosuppression

    Hyaluronic acid (HA) treatment has been successfully performed in patients with recurrent upper airway infections or rhinitis. The aim of this study was to assess the efficacy and safety of the topical nasal administration of an HA-based compound by investigating its effects in children with recurrent or chronic middle ear inflammations and chronic adenoiditis. A prospective, single-blind, 1:1 randomised controlled study was performed to compare otoscopy, tympanometry and pure-tone audiometry in children which received the daily topical administration of normal 0.9% sodium chloride saline solution (control group) or 9 mg of sodium hyaluronate in 3 mL of a 0.9% sodium saline solution. The final analysis was based on 116 children (49.1% boys; mean age, 62.9 ± 17.9 months): 58 in the control group and 58 in the study group. At the end of follow-up, the prevalence of patients with impaired otoscopy was significantly lower in the study group (P value = 0.024) compared to baseline but not in the control group. In comparison with baseline, the prevalence of patients with impaired tympanometry at the end of the follow-up period was significantly lower in the study group (P value = 0.047) but not in the control group. The reduction in the prevalence of patients with conductive hearing loss (CHL) (P value = 0.008) and those with moderate CHL (P value = 0.048) was significant in the study group, but not in the control group. The mean auditory threshold had also significantly improved by the end of treatment in the study group (P value = 0.004) but not in the control group. Our findings confirm the safety of intermittent treatment with a topical nasal sodium hyaluronate solution and are the first to document its beneficial effect on clinical and audiological outcomes in children with recurrent or chronic middle ear inflammations associated with chronic adenoiditis.

    Systemic therapies for inflammatory bowel disease are associated with an increased risk of infections and malignancies. Topical therapies reduce systemic exposure, but can be difficult to retain or have limited proximal distribution. To mitigate these issues, we developed a thermo-sensitive platform, using a polymer-based system that is liquid at room temperature but turns into a viscous gel on reaching body temperature. After rectal administration to mice with dextran sulfate sodium-induced colitis, the platform carrying budesonide or mesalamine becomes more viscoelastic near body temperature. Mice given the drug-containing platform gained more weight and had reduced histologic and biologic features of colitis than mice given the platform alone or liquid drugs via enema. Image analysis showed that enemas delivered with and without the platform reached similar distances in the colons of mice, but greater colonic retention was achieved by using the platform.

    Full Text Available While uterine balloon tamponade is an effective modality for control of postpartum hemorrhage, the reported success rates have ranged from the level of 60% to the level of 80%. In unsuccessful cases, more invasive interventions are needed, including hysterectomy as a last resort. We developed a modified tamponade method and applied it to two cases of refractory postpartum hemorrhage after vaginal delivery. The first case was accompanied by uterine myoma and low-lying placenta. After an induced delivery, the patient had excessive hemorrhage due to uterine atony. Despite oxytocin infusion and bimanual uterine compression, the total blood loss was estimated at 2,800 mL or more. The second case was diagnosed as placental abruption complicated by fetal death and severe disseminated intravascular coagulation, subsequently. A profuse hemorrhage continued despite administration of uterotonics, fluid, and blood transfusion. The total blood loss was more than 5,000 mL. In each case, an intrauterine balloon catheter was wrapped in gauze impregnated with tranexamic acid, inserted into the uterus, and inflated sufficiently with sterile water. In this way, mechanical compression by a balloon and a topical antifibrinolytic agent were combined together. This method brought complete hemostasis and no further treatments were needed. Both the women left hospital in stable condition.

    The Copaiba oil has been used as an auxiliary treatment of inflammations, skin disorders and stomach ulcers, however, in dentistry, this "alternative" medicine has not been investigated yet. The purpose of this study was to evaluate the influence of topic and systemic administration of copaiba oil on the alveolar wound healing after tooth extraction. Twenty-eight wistar male rats had their lower first molar teeth extracted. Subsequently, they were divided in four groups, according to the treatment performed: (a) alveolar socket irrigation with copaiba oil; (b) alveolar socket irrigation with physiological serum; (c) daily gavage with copaiba oil or (d) daily gavage with physiological serum. After the sacrifice, the mandibles were removed and processed in order to obtain decalcified histological sections. The results demonstrated high level of epithelial migration, small number of inflammatory cells and vascular enhancement in the animals which received systemic administration of copaiba oil. The rats treated with topic administration of copaiba oil presented ulcerations and large number of inflammatory cells. An increased bone neoformation was observed in both groups treated with copaiba oil when compared with placebo group. It could be concluded that topic or systemic administration of copaiba oil leads to a better alveolar bone healing, however the topic application on connective tissue should be carefully considered, regarding the whole socket wound healing.

    Nanostructured lipid carriers (NLC) are interesting delivery systems for enhancing the penetration of an active substance through the skin after topical administration. In the present study, lycopene was loaded into NLC, composed of Eumulgin(®) SG, orange wax and rice bran oil, using high pressure homogenization (HPH). Photon correlation spectroscopy analysis showed that the lycopene-loaded NLC had a size of 150-160nm with a relatively small size distribution (PdI<0.15). The entrapment efficiency of lycopene was found to be 100±0% for all formulations. An in vitro release study of lycopene showed a biphasic release profile: a relatively fast release during the first 6h followed by a sustained release during the next 18h. An in vitro occlusion test showed that the occlusive properties of NLC increased with increasing lycopene loading. A free radical scavenging activity test of the NLC loaded with 50mg% lycopene showed a Trolox equivalent antioxidant capacity value of 36.6±0.4μM Trolox/mg NLC which is higher than that of the NLC base (26.6±0.1μM Trolox/mg NLC). The concentration of 50% antioxidant activity (IC50) of the lycopene-loaded NLC was 14.1±0.6mg/mL, and lower than that of the formulation without lycopene (17.7±0.4mg/mL). The particle size, size distribution, and zeta potential of lycopene-loaded NLC stored at different temperatures of 4, 30, 40°C for 120 days did not change in time, demonstrating an excellent colloidal stability of the systems. Chemical stability data indicated that the utilization of NLC increased the stability of lycopene and it was found that the degradation of lycopene was retarded when stored at low temperatures. In conclusion, NLC are attractive systems for the cutaneous delivery of lycopene. PMID:25479097

This study compared the aqueous humour concentration of moxifloxacin following its topical administration in rabbit eyes with two dose regimens. Twelve albino rabbits were divided into two groups. In group-1, two drops were administered thrice (total six drops at 2 min intervals, in both the eyes; in group-2, two drops of moxifloxacin were administered three times a day for three days and also two h before aqueous humour collection i.e. on fourth day. Mean aqueous humour concentrations were calculated and compared using Student′s ′t′ test and P<0.05 was considered significant. Moxifloxacin concentration in aqueous humour in group-1 was 23.79 μg/ml and in group-2 was 42.08 μg/ml. Both dosing regimens produced substantially higher aqueous concentrations than the known minimum inhibitory concentration for most bacteria. Moxifloxacin concentration in aqueous humour with multiple instillations is significantly higher than single instillation (P<0.05, which is adequate to cover ciprofloxacin-resistant gram-negative bacteria. Repeated topical moxifloxacin administration achieved significantly higher aqueous humour concentrations than single administration.

    The human body is constantly exposed to the risk of traumatic lesions. Chlorella is a green microalgae enriched with nutrients, vitamins, minerals and chlorophyll. In some communities, Chlorella is a traditional medicinal plant used for the management of inflammation-related diseases. ROQUETTE Chlorella sp. (RCs) was investigated by oral administration (125, 250 and 500 mg/kg) and cutaneous application (2.5, 5.0 and 10.0%) to evaluate its impact in two dermatological disorder models in mice: skin inflammation and wound healing. For skin inflammation, it was administered during 14 days starting one week before the induction of chronic skin inflammation by repeated cutaneous application of 12-Otetradecanoylphorbol 13-acetate (TPA). For wound healing the microalgae was administered by topical application after scarification of the skin until complete wound healing. Results indicated that oral and topical administrations of the two higher doses of RCs had significant effects on macroscopic score of skin inflammation with an efficient effect on microscopic score with cutaneous application. The microalgae had also efficient effect on healing process and duration of wound healing for both administration routes and particularly at the two highest doses of RCs. These findings suggest that administration of RCs by both oral and topical routes appeared to have beneficial effects on skin lesions. PMID:24965517

  2. The influence on the histological findings of electron irradiated topical tumor tissue under the administration of dexamethasone

    The experimental study was made to examine the influence of dexamethasone on the topical tumor tissue of MM46 tumor bearing C3H/He mice with local exposure of 2,000 and 3,000 rads. In the groups without administration of dexamethasone, tumor cells tended to grow massively and radiation caused intensive lymphocytic infiltration, whereas in the groups with administration of dexamethasone, the tumor cells grew invasively and stromal lymphocytic infiltration was scarecely found both in non-irradiated and irradiated groups with a little difference of reactive cells. These results suggested that dexamethasone suppressed the local immune response. (author)

    This work was undertaken to investigate microemulsion (ME) as a topical delivery system for the poorly water-soluble voriconazole. Different ME components were selected for the preparation of plain ME systems with suitable rheological properties for topical use. Two permeation enhancers were incorporated, namely sodium deoxycholate or oleic acid. Drug-loaded MEs were evaluated for their physical appearance, pH, rheological properties and in vitro permeation studies using guinea pig skin. MEs based on polyoxyethylene(10)oleyl ether (Brij 97) as the surfactant showed pseudoplastic flow with thixotropic behavior and were loaded with voriconazole. Jojoba oil-based MEs successfully prolonged voriconazole release up to 4 h. No significant changes in physical or rheological properties were recorded on storage for 12 months at ambient conditions. The presence of permeation enhancers favored transdermal rather than dermal delivery. Sodium deoxycholate was more effective than oleic acid for enhancing the voriconazole permeation. Voriconazole-loaded MEs, with and without enhancers, showed significantly better antifungal activity against Candida albicans than voriconazole supersaturated solution. In conclusion, the studied ME formulae could be promising vehicles for topical delivery of voriconazole. PMID:21696340

    7,3',4'-Trihydroxyisoflavone (734THIF) is a secondary metabolite of daidzein and has been recently found to possess antioxidant, melanin inhibition, and skin cancer chemopreventive activities. However, the poor water solubility of 734THIF impedes its absorption and skin penetration and, therefore, limits its pharmacological effects when applied topically to the skin. We seek to use the nanoprecipitation method to prepare optimal eudragit E100 (EE)-polyvinyl alcohol (PVA)-loaded 734THIF nanoparticles (734N) to improve its physicochemical properties and thereby increase its water solubility, skin penetration, and biological activities. EE-PVA-loaded 734THIF nanoparticles (734N) were prepared, and their morphology and particle size were evaluated using a particle size analyzer and by electron microscopy. The drug loading and encapsulation efficiencies and in vitro solubility were determined using high-performance liquid chromatography. Hydrogen-bond formation was evaluated by (1)H-nuclear magnetic resonance and Fourier transform infrared spectroscopy, and crystalline-to-amorphous transformation was determined by differential scanning calorimetry and X-ray diffractometry. In vitro skin penetration was analyzed using fresh pig skin mounted on Franz diffusion cells, and cytotoxicity against human keratinocyte HaCaT cells was evaluated using the MTT assay. Antioxidant activity was determined by 2,2-diphenyl-1-picrylhydrazyl-free radical scavenging ability. EE-PVA-loaded 734THIF nanoparticles showed good drug loading and encapsulation efficiencies and were characterized by improved physicochemical properties, including reduction in particle size, amorphous transformation, and intermolecular hydrogen-bond formation. This is associated with increased water solubility and enhanced in vitro skin penetration, with no cytotoxicity toward HaCaT cells. In addition, 734THIF nanoparticles retained their antioxidant activity. In conclusion, 734THIF nanoparticles are characterized by

    Full Text Available Manuka tree is indigenous to New Zealand, and its essential oil has been used as a traditional medicine to treat wounds, fever, and pain. Although there is a growing interest in the use of manuka oil for antiaging skin care products, little is known about its bioactivity. Solar ultraviolet (UV radiation is the primary environmental factor causing skin damage and consequently premature aging. Therefore, we evaluated manuka oil for its effects against photoaging in UV-B-irradiated hairless mice. Topical application of manuka oil suppressed the UV-B-induced increase in skin thickness and wrinkle grading in a dose-dependent manner. Application of 10% manuka oil reduced the average length, depth, and % area of wrinkles significantly, and this was correlated with inhibition of loss of collagen fiber content and epidermal hyperplasia. Furthermore, we observed that manuka oil could suppress UV-B-induced skin inflammation by inhibiting the production of inflammatory cytokines. Taken together, this study provides evidence that manuka oil indeed possesses antiphotoaging activity, and this is associated with its inhibitory activity against skin inflammation induced by UV irradiation.

    Purpose: to quantify the effect of sodium selenite (selenium) on radiation-induced oral mucositis (mouse) after subcutaneous or topical administration. Material and methods: mucosal ulceration of the lower epithelium of mouse tongue was analyzed. Selenium (5 {mu}g) was applied subcutaneously (s.c.) or locally, 60 min or 30 min prior to irradiation, respectively. In combination with single-dose irradiation, a single selenium application was given. With daily fractionated irradiation (3 Gy/fraction) for 1 week (days 0-4), selenium was administered at all 5 days of irradiation. With ten fractions over 2 weeks, selenium was applied in week 1, week 2, or both. All fractionation protocols were terminated by graded test doses to generate full dose-effect curves. Results: in a single-dose control experiment, the ED{sub 50} (dose after which ulcer induction is expected in 50% of the mice) was 12.9 {+-} 1.6 Gy. Selenium increased the ED{sub 50} to 17.7 {+-} 2.6 Gy (s.c.; p = 0.0003) and 16.3 {+-} 3.0 Gy (local; p = 0.0104). The ED{sub 50} for test irradiation after 5 x 3 Gy was 7.4 {+-} 2.2 Gy. Subcutaneous administration of selenium resulted in an ED{sub 50} of 11.5 {+-} 2.0 Gy (p = 0.0015), local application yielded an ED{sub 50} of 10.0 {+-} 2.1 Gy (p = 0.0284). The ED{sub 50} for test irradiation after 10 x 3 Gy/2 weeks was 8.0 {+-} 1.7 Gy. Subcutaneous or local administration of selenium in week 1 yielded a significant increase in ED{sub 50} to 10.5 {+-} 1.0 Gy (p = 0.0069) and 10.7 {+-} 1.0 Gy (p = 0.0039), respectively. By clear contrast, selenium administration in week 2 had no significant effect. Administration in both weeks resulted in an ED{sub 50} of 9.1 {+-} 2.0 Gy (s.c.; p = 0.2747) and 9.7 {+-} 1.4 Gy (local; p = 0.0541). Conclusion: administration of sodium selenite during clinically relevant fractionated irradiation protocols has a significant effect during the initial treatment phase, i.e., week 1 in the mouse. Therefore, in clinical radiotherapy, the

  13. Comparison of topical administration of clotrimazole through surgically placed versus nonsurgically placed catheters for treatment of nasal aspergillosis in dogs: 60 cases (1990-1996)

    To examine the clinical response to topical administration of clotrimazole in dogs with nasal aspergillosis, to compare effect of surgically placed versus nonsurgically placed catheters used for administration on outcome, and to examine whether subjective scoring of computed tomographic images can predict outcome. Retrospective case series. 60 dogs with nasal aspergillosis. Information including signalment, history, diagnostics, treatment method, and outcome was retrieved from medical records of dogs with nasal aspergillosis treated between 1990 and 1996 at the University of California School of Veterinary Medicine or cooperating referral practices. Final outcome was determined by telephone conversations with owners and referring veterinarians. Images obtained before treatment were subjectively assessed to develop an algorithm for predicting outcome. Clotrimazole solution (1%) was infused during a 1-hour period via catheters surgically placed in the frontal sinus and nose (27 dogs) and via nonsurgically placed catheters in the nose (18). An additional 15 dogs received 2 to 4 infusions by either route. Topical administration of clotrimazole resulted in resolution of clinical disease in 65% of dogs after 1 treatment and 87% of dogs after one or more treatments. The scoring system correctly classified dogs with unfavorable and favorable responses 71 to 78% and 79 to 93% of the time, respectively. Topical administration of clotrimazole, using either technique, was an effective treatment for nasal aspergillosis in dogs. Use of non-invasive intranasal infusion of clotrimazole eliminated the need for surgical trephination of frontal sinuses in many dogs and was associated with fewer complications

    Current systematic review evaluated the efficacy of topical isoflavones to relieve vaginal symptoms in menopausal women. MEDLINE (1966 to January 2014), Scopus (1990 to January 2014), and the Cochrane Central Register of Controlled Trials (The Cochrane Library issue 1, 2013) were searched using keywords 'isoflavone and vagina'. Relevant studies were reviewed by two independent reviewers. Only randomised controlled trials (RCTs) were included in the systematic review. Out of 115 potentially relevant publications, four studies met the inclusion criteria. Topical isoflavones showed beneficial effects on dyspareunia, vaginal dryness and maturation value. Based on only one trial, the result of conjugated equine oestrogen cream (0.3 mg/day) was similar to use of isoflavone vaginal gel and superior to that of placebo gel. However, drawing any definite conclusion was difficult because of the limited number of RCTs, the small sample sizes, weak methodology and considerable heterogeneity of the included studies.

    Nicotine has been reported to prolong the wound healing; however, we showed that the topical application of 10(-4) M nicotine promoted murine wound healing. The objective of this study was to explore the wound healing effects of nicotine in combination with collagen scaffold using skin defects in rabbit. Three full-thickness skin defects 8 mm in diameter were made on the rabbit auricle. Artificial dermis was applied to the defects, and 10 μl of nicotine solution (10(-5), 10(-4), and10(-3) M), bFGF solution (0.5 μg/10 μl), and both bFGF and 10(-4) M nicotine solutions were injected into the artificial dermis once daily for 7 days. Rabbits were sacrificed on day 10, 15, or 20, and the wound healing process was evaluated. bFGF was superior in the formation of the dermis-like tissue and capillaries. In nicotine groups, the epithelial length and the dermis-like tissue formations in the 10(-4) M group were superior, in contrast, those were inhibited in the 10(-3) M group. The synergistic effect of bFGF and 10(-4) M nicotine was not confirmed. This study suggests that the topical application of 10(-4) M nicotine promoted wound healing in rabbit, but the effect was not apparent compared with murine models. PMID:26497310

    Objective: This study aims to investigate the clinical performance of three-dimensional (3D) fast-recovery fast spin-echo (FRFSE) magnetic resonance dacryocystography (MRD) with topical administration of sterile saline solution for the assessment of the lacrimal drainage system (LDS). Methods: A total of 13 healthy volunteers underwent both 3D-FRFSE MRD and two-dimensional (2D)-impulse recovery (IR)-single-shot fast spin-echo (SSFSE) MRD after topical administration of sterile saline solution, and 31 patients affected by primary LDS outflow impairment or postsurgical recurrent epiphora underwent 3D-FRFSE MRD and conventional T1- and T2-weighted sequences. All patients underwent lacrimal endoscopy or surgery, which served as a standard of reference for confirming the MRD findings. Results: 3D-FRFSE MRD detected more visualized superior and inferior canaliculi and nasolacrimal duct than 2D-IR-SSFSE MRD. Compared with 2D-IR-SSFSE MRD, 3D-FRFSE MRD showed more visualized segments per LDS, although the difference was not statistically significant. Significant improvements in the inferior canaliculus and nasolacrimal duct visibility grades were achieved using 3D-FRFSE MRD. 3D-FRFSE MRD had 100% sensitivity and 63.6% specificity for detecting LDS obstruction. In 51 out of the 62 LDSs that were assessed, a 90% agreement was noted between the findings of 3D-FRFSE MRD and lacrimal endoscopy in detecting the obstruction level. Conclusion: 3D-FRFSE MRD combined with topical administration of sterile saline solution is a simple and noninvasive method of obtaining detailed morphological and functional information on the LDS. Overall, 3D-FRFSE MRD could be used as a reliable diagnostic method in many patients with epiphora prior to surgery

  3. Topical administration of Tetrasodium-Mesotetraphenyl-Porphinesulfonate (TPPS): correlations between drug penetration and depth of necrosis in skin of nude mice following red light irradiation

    International Nuclear Information System (INIS)

    The main side effect in photodynamic therapy is photosensitization of the patient's skin following systemic administration of the photosensitizing agent. In the case of superficial lesions, this problem can be avoided by topically applying the drug: in this way a local treatment can be performed. The photosensitizing properties of a 2% solution of TPPS (Tetrasodium-Tetraphenylpophinesulfonate) in a vehicle containing a penetration enhancer, Azone, on skin of nude mice has been tested. An aliquot of 0.1 ml/cm2 of the solution was painted on the skin overlying an s.c. implanted NMU-1 tumor. Subsequently, animals were sacrificed at different times after applications. Fluorescence microscopy revealed that TPPS penetration depth was related to time elapsed after application and to painting modalities. Solution penetration was enhanced by wiping with ether immediately before painting. Irradiation at 80 mW/cm2 for 20 min with a dye laser emitting at 640 nm, 4 h after TPPS applications, produced necrosis of the upper skin layers, up to 0.2 mm in depth. These findings suggest that topical TPPS administration, followed by laser irradiation, may be a suitable treatment modality for skin lesions involving epithelial layers, even though several aspects of this methodology need further investigation

    The literature contains a number of reports of death following the intravenous administration of fructose in patients with hereditary fructose intolerance (HFI). The aim of the present study was, therefore, to investigate the metabolic changes occurring during intravenous administration of fructose to patients with HFI, with the aim of identifying metabolic parameters that would permit the early diagnosis of HFI. Also, the deaths reported in the literature were analyzed. In three of our own patients with fruit intolerance known since childhood, and in volunteers with normal metabolism, a one-hour intravenous fructose tolerance test (1.7 g fructose/min) was performed. An analysis was done using the usual enzymatic and chemical methods: blood glucose, fructose, lactic acid, serum uric acid, ammonia, free fatty acids, inorganic phosphate, and serum amino acids (ion exchange chromatography). During fructose infusion, the following metabolic changes were detected: hypoglycemia (20 to 60 mg/dl), increase in blood fructose levels (up to 350 mg/dl), hypophosphatemia (2 to 3 mg/dl), hyperlacticacidemia (up to 60 mg/dl), elevation of plasma ammonia levels (up to 120 mg/dl), increased serum glutamate, and a decrease in serum glutamine, as also hyperuricemia (up to 10 mg/dl). On termination of the fructose infusion, these changes were completely reversible. Analysis of the deaths reported in the literature revealed a known intolerance to fruit or sweets, and that no regular metabolic studies were apparently performed. Although HFI is rare, use should be made of the known advantages of sugar substitutes in post-aggression metabolism.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:1770897

    The prominent nitric oxide (NO) donor [Ru(terpy)(bdqi)NO](PF(6))(3) has been synthesized and evaluated with respect to noteworthy biological effects due to its NO photorelease, including vascular relaxation and melanoma cell culture toxicity. The potential for delivering NO in therapeutic quantities is tenable since the nitrosyl ruthenium complex (NRC) must first reach the "target tissue" and then release the NO upon stimulus. In this context, NRC-loaded lipid carriers were developed and characterized to further explore its topical administration for applications such as skin cancer treatment. NRC-loaded solid lipid nanoparticles (SLN) and nanostructured lipid carriers were prepared via the microemulsification method, with average diameters of 275+/-15 nm and 211+/-31 nm and zeta potentials of -40.7+/-10.4 mV and -50.0+/-7.5 mV, respectively. In vitro kinetic studies of NRC release from nanoparticles showed sustained release of NRC from the lipid carriers and illustrated the influence of the release medium and the lyophilization process. Stability studies showed that NO is released from NRC as a function of temperature and time and due to skin contact. The encapsulation of NRC in SLN followed by its lyophilization, significantly improved the complex stability. Furthermore, of particular interest was the fact that in the NO photorelease study, the NO release from the NRC-loaded SLN was approximately twice that of just NRC in solution. NRC-loaded SLN performs well enough at releasing and protecting NO degradation in vitro that it is a promising carrier for topical delivery of NO. PMID:20634015

    Nonionic surfactants (caprylocaproyl macrogol-8 glycerides, octoxynol-12, polysorbate-20, and polyethylene glycol-40 hydrogenated castor oil) (47.03%, w/w), costabilizer (poloxamer 407) (12%-20%, w/w), oil (isopropyl myristate) (5.22%, w/w), water (q.s. ad 100%, w/w), and ibuprofen (5%, w/w) were used to develop oil-in-water microemulsions with Newtonian flow behavior, low viscosity (from 368 ± 38 to 916 ± 46 mPa s), and average droplet size from 14.79 ± 0.31 to 16.54 ± 0.75 nm. Ibuprofen in vitro release from the microemulsions was in accordance with zero-order kinetics (R0(2) > 0.99) for at least 12 h. The maximum drug release rate (3.55%h(-1) ) was from the microemulsion M3 comprising 16%, w/w of poloxamer 407. The release rate of ibuprofen from the reference hydrogel followed Higuchi kinetics (RH(2) > 0.99), and drug amount released after the 6th hour was negligible. In a rat model of inflammation, the microemulsion M3 was significantly more efficacious than the reference hydrogel in exerting antihyperalgesic effects in prophylactic topical treatment, whereas they were comparable in therapeutic treatment as well as in producing antiedematous effect in both protocols. No obvious skin irritation was observed in in vivo studies. The developed nonionic surfactants-based microemulsions containing the optimal concentration of poloxamer 407 could be promising carriers for sustained regional delivery of ibuprofen via topical administration.

    Sunburn, immune suppression, photo-aging, and skin cancers result from uncontrolled overexposure of human skin to solar ultraviolet radiation (UVR). Preventive measures, including photo-protection, are helpful and can be achieved by topical sun-screening agents. Polypodium leucotomos (PL) has been used for the treatment of inflammatory diseases and has shown some in vitro and in vivo immunomodulating properties. Its beneficial photo-protective effects in the treatment of vitiligo and its antioxidant properties encouraged us to evaluate in vivo the potentially useful photo-protective property of natural extract of PL after topical application or oral ingestion. Twenty-one healthy volunteers [either untreated or treated with oral psoralens (8-MOP or 5-MOP)] were enrolled in this study and exposed to solar radiation for evaluation of the following clinical parameters: immediate pigment darkening (IPD), minimal erythema dose (MED), minimal melanogenic dose (MMD), and minimal phototoxic dose (MPD) before and after topical or oral administration of PL. Immunohistochemical assessment of CD1a-expressing epidermal cells were also performed. PL was found to be photo-protective after topical application as well as oral administration. PL increased UV dose required for IPD (P<0.01), MED (P<0.001) and MPD (P<0.001). After oral administration of PL, MED increased 2.,8{+-}0.59 times and MPD increased 2.75{+-}0.5 and 6.8{+-}1.3 times depending upon the type of psoralen used. Immunohistochemical study revealed photo-protection of Langherhans cells by oral as well as topical PL. The observed photo-protective activities of oral or topical PL reveal a new avenue in examining the potentially useful field of systemic photo-protection and suggests that PL can be used as adjunct treatment and can make photochemotherapy and phototherapy possibly safe and effective when the control of cutaneous phototoxicity to PUVA or UVB is a limiting factor in such photo-therapies.

    This study describes the development of a sensitive high-performance liquid chromatography-electrospray ionization-tandem mass spectrometry (LC-ESI-MS/MS) method for the quantification of avobenzone in rat plasma and skin layers. Separations were performed on a Zorbax SB C8 column using a binary gradient mobile phase composed of acetonitrile and 0.1% formic acid in water. The assay achieved LLOQ of 0.5ng/ml for plasma, 5ng/ml for stratum corneum, and 10ng/ml for epidermis and dermis. This method was applied to a percutaneous absorption study of avobenzone in rats. At 12h following topical application of emulsion and lotion (applied amount of avobenzone 11.7mg/kg), avobenzone was found primarily in the stratum corneum (16.3-17.8%) followed by epidermis (2.0-3.4%) and dermis (0.11-0.15%). Avobenzone was not quantifiable in the plasma samples collected over a 12h sampling period. Given the excellent plasma assay sensitivity, this study provides evidence that the systemic absorption of avobenzone is insignificant, if any, after topical application. PMID:26409261

  16. Spotlight Topics

    Science.gov (United States)

    A Spotlight Topic consists of a set of two or more review articles focused on a specific subject in surface science. The topics are recommended by the Board of Editors. A topic may be chosen because it is particularly new or fast-breaking, thus deserving introduction to the general readership. Or, it may be because a topic is especially controversial or confusing, requiring clarification by experts. Each review will give a critical assessment rather than an encyclopedic report. While our editors always will insist on fairness and accuracy, any review which forwards an opinion is bound to be somewhat subjective. Therefore, it is the editors' wish that the set of reviews written by different authors on the same subject matter will provide a broad and balanced viewpoint. It is often the case that an author who is an expert in a technique or method may be especially enthusiastic or critical about this technique or method. A companion review in the set may provide a different viewpoint. We are hopeful that the reader, after studying these reviews and checking some of the key references, will obtain an informed opinion of the subject. We think the set of reviews in a spotlight area will considerably shorten the ``learning time'' that a nonexpert would otherwise need to become knowledgeable about a subject. In this issue, we feature a spotlight topic on oxide surfaces. The set contains an overview article by Jacques Jupille, and four articles written by G. Pacchioni, F. Cosandey and T. E. Madey, B. G. Daniels, R. Lindsay and G. Thornton, and C. Noguera respectively. Of these, the article by Pacchioni has already appeared in SRL 7, 277 (2000). The other three articles appear in this issue. A reader who wishes to suggest a spotlight topic or recommend authors to write such reviews should contact the Editor-in-Chief. We would like to hear from you.

It covers errors that can arise during the segment's installation and deinstallation, and it outlines appropriate recovery actions. It also tells how to extend the database storage available to Oracle if a datastore becomes filled during the use of ELIST. The latter subject builds on some of the actions that must be performed when installing this segment, as documented in the Installation Procedures (IP) for the Enhanced Logistics Intratheater Support Tool (ELIST) Global Data Segment, Database Instance Segment, Database Fill Segment, Database Segment, Database Utility Segment, Software Segment, and Reference Data Segment (referred to in portions of this document as the ELIST IP). The information in this document is expected to be of use only rarely. Other than errors arising from the failure to follow instructions, difficulties are not expected to be encountered during the installation or deinstallation of the segment. The need to extend database storage likewise typically arises infrequently.

    Full Text Available Many expected freedom of information laws to be among the first priorities of the new governments of countries in transition after the 1989 changes, but instead there was little public pressure to adopt general sunshine laws relating to all categories of information. After adopting the laws, however, there are still many powerful forces that are working against extensive access to information – they can be static - opaque administrative practices, general inaptitude or the lack of sufficient human and material resources - or active – agents that resist openness due to private interests, or agents that use institutional scenarios to prevent public scrutiny over corruption and incompetence. The paper approaches the jurisdictions from Hungary, Poland, Czech Republic and Romania, emphasising aspects like: different models in regulating freedom of information regimes, obstacles in the implementation of the law, public bodies that should apply the law, timeframes, etc.

    Purpose: to investigate the cytoprotective effect of intrarectal amifostine administration on acute radiation-induced rectal toxicity. Patients and methods: 67 patients with T1b-2 NO MO prostate cancer were randomized to receive amifostine intrarectally (group A, n - 33) or not (group B, n = 34) before irradiation. Therapy was delivered using a four-field technique with three-dimensional conformal planning. In group A, 1,500 mg amifostine was administered intrarectally as an aqueous solution in a 40-ml enema. Two different toxicity scales were used: EORTC/RTOG rectal and urologic toxicity criteria along with a Subjective-RectoSigmoid (S-RS) scale based on the endoscopic terminology of the World Organization for Digestive Endoscopy. Objective measurements with rectosigmoidoscopy were performed at baseline and 1-2 days after the completion of radiotherapy. The area under curve for the time course of mucositis (RTOG criteria) during irradiation represented the mucositis index (MI). Results: intrarectal amifostine was feasible and well tolerated without any systemic or local side effects. According to the RTOG toxicity scale, five out of 33 patients showed grade 1 mucositis in group A versus 15 out of 34 patients with grade 1/2 in group B (p = 0.026). Mean rectal MI was 0.3 {+-} 0.1 in group A versus 2.2 {+-} 0.4 in group B (p < 0.001), while S-RS score was 3.9 {+-} 0.5 in group A versus 6.3 {+-} 0.7 in group B (p < 0.001). The incidence of urinary toxicity was the same in both groups. Conclusion: intrarectal administration of amifostine seems to have a cytoprotective efficacy in acute radiation-induced rectal mucositis. Further randomized studies are needed for definitive therapeutic decisions. (orig.)

    Topical retinoids are currently approved by the US Food and Drug Administration for the treatment of acne vulgaris in nonpregnant, nonlactating patients 12 years of age and older. Their efficacy, safety, and tolerability are well documented for inflammatory and noninflammatory acne with studies repeatedly demonstrating a decrease in the number of lesions, significant improvement in acne severity, improvement in the cosmetic appearance of acne, and the prevention of acne lesions through microcomedone formation. There is some variability between prescription retinoid products regarding efficacy, safety, and tolerability; with erythema, peeling, and dryness being common, potential side effects. Due to their efficacious and safe profile, topical retinoids remain the first-line treatment for acne vulgaris. PMID:27416308

    Recently there has been little interest in topical contraceptives. The most popular are the cervical cap and the diaphragm. Other types of mechanical contraceptive devices are being investigated. Standley and Kessler have developed a device for introduction into the cervical canal with a reservoir of spermatocide, it does not block the flow of blood during menstruation. New models of vaginal rings are also being developed which are simple enough for self-insertion and also contain a reservoir of spermatocide. Work is being done on spermatocide-containing sponges in many countries. Another project being investigated is the possibility of using natural proteins, collagens, and other substances which absorb spermatozoids. The ancients used various vaginal suppositories to kill spermatozoids; in the late 19th century quinine sulfate was used for this, and a variety of substances have been used recently. These spermicidal creams also have the advantage of acting as anti-infectious agents in many cases. But they do have some negative effects. They are about 85% effective, are local irritants, and some cause discomfort during intercourse. And it is possible that some are resorbed by the body and act on the liver and other organs. Vaginal globules and suppositories are also popular. The "Kontraceptin-T" brand contains quinosol, boric acid, and tannin. There are also foaming tablets which are mixed with water and then introduced. New locally-active chemical substances are being developed in Japan, West Germany, and the USSR. Kontraceptin-E contains paranonyl-phenoxypolyethylene glycol and sodium dioctylsulfosuccinate. The "Norforks" and other preparations contain mercurial compounds which may turn out to be harmful. The future promises the development of products which will act to prevent fertilization by acting on the hyaluronidase and the acrosine of the spermatozoid, thus preventing it from penetrating the ovum. It would be best to find enzyme inhibitors which are

    A simple, rapid and highly sensitive LC-MS/MS method was developed and validated for the determination of ketoconazole in human plasma. Sample preparation was accomplished through a single step liquid-liquid extraction by ethyl acetate. The chromatography separation was carried out on a Hedera CN (150mm×2.1mm, 5μm) column with isocratic elution using acetonitrile and 10mM ammonium acetate containing 0.1% formic acid (45:55, v/v) as the mobile phase. The flow rate was 0.5mL/min. Detection was performed in the positive ion electrospray ionization mode using multiple reaction monitoring of the transitions of 531.2→489.3 and 286.1→217.1 for ketoconazole and letrozole (the internal standard), respectively. The method exhibited good linearity over the concentration range of 0.01-12ng/mL for ketoconazole. The intra- and inter-batch precision and accuracy of ketoconazole were all within the acceptable criteria. The method was successfully applied to a clinical study of the exposure to ketoconazole in Chinese seborrheic dermatitis patients after topical administration of two ketoconazole formulations of foam and lotion, respectively. The study results showed that there was little systemic absorption of ketoconazole in patients for the two formulations, and the ketoconazole foam and lotion are safe therapeutic drugs for seborrheic dermatitis patients.

    Topically applied analgesic therapies have been used throughout history to treat a variety of patient conditions that present with pain. Before modem pharmaceuticals became readily available, mud-based emollients, salves, cold therapies, and other natural remedies were often used. Now we have effective therapies and are developing advanced topical analgesics as we learn more about the physiology and pathophysiology of pain. The use of topical analgesics may be associated with fewer patient systemic side effects than are seen with oral, parenteral, or transdermally administered agents, making the topical route of administration attractive to prescribers and patients. With further refinement of existing drugs and the development of novel agents, topical analgesics may offer relief for treating patient pain conditions that are currently challenging to treat, such as pain resulting from burns, wound debridement, and pressure ulcers. Recognizing the value of a multimodal approach, topical analgesics may offer a therapeutic option that can become part of a comprehensive treatment plan for the patient. With continued advancements in targeted drug-delivery systems, topical analgesics may be able to provide a method to prevent or reverse the phenomena of peripheral and central sensitization, or the neuroplastic changes believed to be responsible for the transition from acute to chronic pain states in patients. For those patients at risk for developing chronic pain states, such as complex regional pain syndrome, the combination of cutaneous stimulation (achieved through rubbing during application) and analgesic effects produced by the drug itself may prevent the disabling pain that often emerges during the subacute phase of disease. In summary, better utilization of currently available topical analgesics and continued research promise to ensure that topical analgesics are, and will continue to be, important tools in the treatment of patients with resistant pain.

  13. Syntactic Topic Models

    CERN Document Server

    Boyd-Graber, Jordan

    2010-01-01

    The syntactic topic model (STM) is a Bayesian nonparametric model of language that discovers latent distributions of words (topics) that are both semantically and syntactically coherent. The STM models dependency parsed corpora where sentences are grouped into documents. It assumes that each word is drawn from a latent topic chosen by combining document-level features and the local syntactic context. Each document has a distribution over latent topics, as in topic models, which provides the semantic consistency. Each element in the dependency parse tree also has a distribution over the topics of its children, as in latent-state syntax models, which provides the syntactic consistency. These distributions are convolved so that the topic of each word is likely under both its document and syntactic context. We derive a fast posterior inference algorithm based on variational methods. We report qualitative and quantitative studies on both synthetic data and hand-parsed documents. We show that the STM is a more pred...

  14. Is topical haloperidol a useful glaucoma treatment?

    1986-01-01

    A randomised, double blind, single dose study of topical haloperidol, a dopamine receptor blocking drug, was performed on 20 healthy volunteers. After its administration a modest reduction in intraocular pressure was recorded over the six-hour study period, but the difference was not significant at the p less than 0.05 level. Although dopamine blocking agents are effective in reducing intraocular pressure in experimental animals, topical haloperidol appears unlikely to be clinically useful in...

    Cohen, Gadi; Natsheh, Hiba; Sunny, Youhan; Bawiec, Christopher R; Touitou, Elka; Lerman, Melissa A; Lazarovici, Philip; Lewin, Peter A

    2015-09-01

    The purpose of this work was to investigate whether low-frequency, low-intensity (20 kHz, <100 mW/cm(2), spatial-peak, temporal-peak intensity) ultrasound, delivered with a lightweight (<100 g), tether-free, fully wearable, battery-powered applicator, is capable of reducing inflammation in a mouse model of rheumatoid arthritis. The therapeutic, acute, anti-inflammatory effect was estimated from the relative swelling induced in mice hindlimb paws. In an independent, indirect approach, the inflammation was bio-imaged by measuring glycolytic activity with near-infrared labeled 2-deoxyglucose. The outcome of the experiments indicated that the combination of ultrasound exposure and topical application of 0.1% (w/w) betamethasone gel resulted in statistically significantly (p < 0.05) enhanced anti-inflammatory activity in comparison with drug or ultrasound treatment alone. The present study underscores the potential benefits of low-frequency, low-intensity ultrasound-assisted drug delivery. However, the proof of concept presented indicates the need for additional experiments to systematically evaluate and optimize the potential of, and the conditions for, tolerable low-frequency, low-intensity ultrasound-promoted non-invasive drug delivery.

    2009-01-01

    Full Text Available Melasma is a common hypermelanotic disorder affecting the face that is associated with considerable psychological impacts. The management of melasma is challenging and requires a long-term treatment plan. In addition to avoidance of aggravating factors like oral pills and ultraviolet exposure, topical therapy has remained the mainstay of treatment. Multiple options for topical treatment are available, of which hydroquinone (HQ is the most commonly prescribed agent. Besides HQ, other topical agents for which varying degrees of evidence for clinical efficacy exist include azelaic acid, kojic acid, retinoids, topical steroids, glycolic acid, mequinol, and arbutin. Topical medications modify various stages of melanogenesis, the most common mode of action being inhibition of the enzyme, tyrosinase. Combination therapy is the preferred mode of treatment for the synergism and reduction of untoward effects. The most popular combination consists of HQ, a topical steroid, and retinoic acid. Prolonged HQ usage may lead to untoward effects like depigmentation and exogenous ochronosis. The search for safer alternatives has given rise to the development of many newer agents, several of them from natural sources. Well-designed controlled clinical trials are needed to clarify their role in the routine management of melasma.

Previously, science and mathematics were part of natural philosophy and many mathematical theories arose as a result of trying to understand natural phenomena. This situation changed at the beginning of last century as science and mathematics diverged. These two fields are collaborating once again; 'Topics in Mathematical Physics' takes the reader through this journey.

    In applications we may want to compare different document collections: they could have shared content but also different and unique aspects in particular collections. This task has been called comparative text mining or cross-collection modeling. We present a differential topic model for this application that models both topic differences and similarities. For this we use hierarchical Bayesian nonparametric models. Moreover, we found it was important to properly model power-law phenomena in topic-word distributions and thus we used the full Pitman-Yor process rather than just a Dirichlet process. Furthermore, we propose the transformed Pitman-Yor process (TPYP) to incorporate prior knowledge such as vocabulary variations in different collections into the model. To deal with the non-conjugate issue between model prior and likelihood in the TPYP, we thus propose an efficient sampling algorithm using a data augmentation technique based on the multinomial theorem. Experimental results show the model discovers interesting aspects of different collections. We also show the proposed MCMC based algorithm achieves a dramatically reduced test perplexity compared to some existing topic models. Finally, we show our model outperforms the state-of-the-art for document classification/ideology prediction on a number of text collections. PMID:26353238

  13. Contrastive topics decomposed

    Directory of Open Access Journals (Sweden)

    Michael Wagner

    2012-12-01

    Full Text Available The analysis of contrastive topics introduced in Büring 1997b and further developed in Büring 2003 relies on distinguishing two types of constituents that introduce alternatives: the sentence focus, which is marked by a FOC feature, and the contrastive topic, which is marked by a CT feature. A non-compositional rule of interpretation that refers to these features is used to derive a topic semantic value, a nested set of sets of propositions. This paper presents evidence for a correlation between the restrictive syntax of nested focus operators and the syntax of contrastive topics, a correlation which is unexpected under this analysis. A compositional analysis is proposed that only makes use of the flatter focus semantic values introduced by focus operators. The analysis aims at integrating insights from the original analysis while at the same time capturing the observed syntactic restrictions. http://dx.doi.org/10.3765/sp.5.8 BibTeX info

  17. Topic Tracking with Dynamic Topic Model and Topic-based Weighting Method

    Directory of Open Access Journals (Sweden)

    Xiaoyan Zhang

    2010-05-01

    Full Text Available In topic tracking, a topic is usually described by several stories. How to represent a topic is always an issue and a difficult problem in the research on topic tracking. To emphasis the topic in stories, we provide an improved topic-based tf*idf weighting method to measure the topical importance of the features in the representation model. To overcome the topic drift problem and filter the noise existed in the tracked topic description, a dynamic topic model is proposed based on the static model. It extends the initial topic model with the information from the incoming related stories and filters the noise using the latest unrelated story. The topic tracking systems are implemented on the TDT4 Chinese corpus. The experimental results indicate that both the new weighting method and the dynamic model can improve the tracking performance.

    This topical issue of Physica Scripta collects selected peer-reviewed contributions based on invited and contributed talks and posters presented at the 15th Central European Workshop on Quantum Optics (CEWQO) which took place in Belgrade 29 May-3 June 2008 (http://cewqo08.phy.bg.ac.yu). On behalf of the whole community took place in Belgrade 29 May-3 June 2008 (http://cewqo08.phy.bg.ac.yu, cewqo08.phy.bg.ac.yu). On behalf of the whole community of the workshop, we thank the referees for their careful reading and useful suggestions which helped to improve all of the submitted papers. A brief description of CEWQO The Central European Workshop on Quantum Optics is a series of conferences started informally in Budapest in 1992. Sometimes small events transform into important conferences, as in the case of CEWQO. Professor Jozsef Janszky, from the Research Institute of Solid State Physics and Optics, is the founder of this series. Margarita Man'ko obtained the following information from Jozsef Janszky during her visit to Budapest, within the framework of cooperation between the Russian and Hungarian Academies of Sciences in 2005. He organized a small workshop on quantum optics in Budapest in 1992 with John Klauder as a main speaker. Then, bearing in mind that a year before Janszky himself was invited by Vladimir Buzek to give a seminar on the same topic in Bratislava, he decided to assign the name 'Central European Workshop on Quantum Optics', considering the seminar in Bratislava to be the first workshop and the one in Budapest the second. The third formal workshop took place in Bratislava in 1993 organized by Vladimir Buzek, then in 1994 (Budapest, by Jozsef Janszky), 1995 and 1996 (Budmerice, Slovakia, by Vladimir Buzek), 1997 (Prague, by Igor Jex), 1999 (Olomouc, Czech Republic, by Zdenek Hradil), 2000 (Balatonfüred, Hungary, by Jozsef Janszky ), 2001 (Prague, by Igor Jex), 2002 (Szeged, Hungary, by Mihaly Benedict), 2003 (Rostock,Germany, by Werner Vogel and

  5. Nanoparticles - A paradigm for topical drug delivery

    Directory of Open Access Journals (Sweden)

    Yogesh S Chaudhari

    2012-01-01

    Full Text Available Topical drug delivery is still a challenge due to the difficulties in controlling the active pharmaceutical ingredient (API fate within the skin. Due to the safety of the component material and controlled release abilities, nanoparticles offer an excellent opportunity for the rational delivery of drugs to the desired target site and hence these carrier systems are effectively used for topical delivery of variety of active principles for both pharmaceutical as well as cosmetic purposes. Recently, solid lipid nanoparticles (SLNs have shown a great potential as carriers for topical administration of active substances, principally owing to the possible targeting effect and controlled release in different skin strata. Also, nanostructured lipid carriers (NLCs are a new type of topical delivery system offering improved performance in terms of drug loading and long-term stability with the ability to form highly concentrated dispersions. Another invention in the field of topical drug delivery is the use of micellar nanoparticles (MNPs that offer a potentially fast and inexpensive pharmaceutical development model by using drugs already proven safe and effective to create new proprietary formulations. These novel drug delivery systems have gained much interest as they combine both the technology of lipid sciences and nanosciences, and hence may be better alternative carriers.

  6. Topics on continua

    CERN Document Server

    Macias, Sergio

    2005-01-01

    Specialized as it might be, continuum theory is one of the most intriguing areas in mathematics. However, despite being popular journal fare, few books have thoroughly explored this interesting aspect of topology. In Topics on Continua, Sergio Macías, one of the field's leading scholars, presents four of his favorite continuum topics: inverse limits, Jones's set function T, homogenous continua, and n-fold hyperspaces, and in doing so, presents the most complete set of theorems and proofs ever contained in a single topology volume. Many of the results presented have previously appeared only in research papers, and some appear here for the first time. After building the requisite background and exploring the inverse limits of continua, the discussions focus on Professor Jones''s set function T and continua for which T is continuous. An introduction to topological groups and group actions lead to a proof of Effros''s Theorem, followed by a presentation of two decomposition theorems. The author then offers an...

    CERN Document Server

    Burkhardt, Charles E

    2006-01-01

    The study of atomic physics propelled us into the quantum age in the early twentieth century and carried us into the twenty-first century with a wealth of new and, in some cases, unexplained phenomena. Topics in Atomic Physics provides a foundation for students to begin research in modern atomic physics. It can also serve as a reference because it contains material that is not easily located in other sources. A distinguishing feature is the thorough exposition of the quantum mechanical hydrogen atom using both the traditional formulation and an alternative treatment not usually found in textbooks. The alternative treatment exploits the preeminent nature of the pure Coulomb potential and places the Lenz vector operator on an equal footing with other operators corresponding to classically conserved quantities. A number of difficult to find proofs and derivations are included as is development of operator formalism that permits facile solution of the Stark effect in hydrogen.

  14. Topics in statistical mechanics

    Energy Technology Data Exchange (ETDEWEB)

    Elser, V.

    1984-05-01

    This thesis deals with four independent topics in statistical mechanics: (1) the dimer problem is solved exactly for a hexagonal lattice with general boundary using a known generating function from the theory of partitions. It is shown that the leading term in the entropy depends on the shape of the boundary; (2) continuum models of percolation and self-avoiding walks are introduced with the property that their series expansions are sums over linear graphs with intrinsic combinatorial weights and explicit dimension dependence; (3) a constrained SOS model is used to describe the edge of a simple cubic crystal. Low and high temperature results are derived as well as the detailed behavior near the crystal facet; (4) the microscopic model of the lambda-transition involving atomic permutation cycles is reexamined. In particular, a new derivation of the two-component field theory model of the critical behavior is presented. Results for a lattice model originally proposed by Kikuchi are extended with a high temperature series expansion and Monte Carlo simulation. 30 references.

  16. Superconcentration and related topics

    CERN Document Server

    Chatterjee, Sourav

    2014-01-01

    A certain curious feature of random objects, introduced by the author as “super concentration,” and two related topics, “chaos” and “multiple valleys,” are highlighted in this book. Although super concentration has established itself as a recognized feature in a number of areas of probability theory in the last twenty years (under a variety of names), the author was the first to discover and explore its connections with chaos and multiple valleys. He achieves a substantial degree of simplification and clarity in the presentation of these findings by using the spectral approach. Understanding the fluctuations of random objects is one of the major goals of probability theory and a whole subfield of probability and analysis, called concentration of measure, is devoted to understanding these fluctuations. This subfield offers a range of tools for computing upper bounds on the orders of fluctuations of very complicated random variables. Usually, concentration of measure is useful when more direct prob...

    The Accellera Universal Verification Methodology (UVM) standard is architected to scale, but verification is growing and in more than just the digital design dimension. It is growing in the SoC dimension to include low-power and mixed-signal and the system integration dimension to include multi-language support and acceleration. These items and others all contribute to the quality of the SOC so the Metric-Driven Verification (MDV) methodology is needed to unify it all into a coherent verification plan. This book is for verification engineers and managers familiar with the UVM and the benefits it brings to digital verification but who also need to tackle specialized tasks. It is also written for the SoC project manager that is tasked with building an efficient worldwide team. While the task continues to become more complex, Advanced Verification Topics describes methodologies outside of the Accellera UVM standard, but that build on it, to provide a way for SoC teams to stay productive and profitable.

    Dynamic topic models (DTMs) are very effective in discovering topics and capturing their evolution trends in time series data. To do posterior inference of DTMs, existing methods are all batch algorithms that scan the full dataset before each update of the model and make inexact variational approximations with mean-field assumptions. Due to a lack of a more scalable inference algorithm, despite the usefulness, DTMs have not captured large topic dynamics. This paper fills this research void, a...

    simulations 'would be seriously in error'. One may ask if this magazine should give space to Lindzen or those involved in geoengineering to air their views. Given the uncertainties still present within climate models and the potential costs of dealing with global warming, it would be wrong for Physics World to ignore those outside the mainstream. After all, as Richard Feynman once wrote: 'There is no harm in doubt and scepticism, for it is through these that new discoveries are made'. Physicists should never take anything at face value, not least a topic as important as climate change. (U.K.)

    The purpose of this Risk Management Plan (RMP) is to establish the concept and define the process to assure that National Nuclear Security Administration Nevada Operations Office Environmental Management (NNSA/NV EM) programs and projects incorporate appropriate, efficient, cost-effective measures to mitigate the impact of program-and/or project-related risks. In addition, it describes the roles and responsibilities of program personnel in performing the risk management functions, and defines reporting and tracking requirements for risk-related information. The product of this risk analysis will be a risk analysis report listing the various risks with their classification, mitigation and handling strategies, impact on cost and schedule, and action items. The risk management process will identify potential risk sources; assess individual risks and impacts on performance, cost, and schedule; evaluate alternative approaches to mitigate high and moderate risks; develop action plans to handle individual risks; and interface risks with other programs and/or projects. Risk management and risk assessment will be consistent with DOE Orders 430.1 and 413.3 and their associated guidance documentation. The RMP will remain valid for the life cycle of the program and/or projects and will be under configuration control with revisions to be conducted as required and approved

    Kircik, Leon H

    2016-02-01

    The primary treatment for superficial fungal infections is antifungal topical formulations, and allylamines and azoles represent the two major classes of topical formulations that are used to treat these infections. The stratum corneum (SC) is composed of keratinocytes that are surrounded by a matrix of lipids. The efficacy of topically applied formulations depends on their ability to penetrate this lipid matrix, and the vehicle plays an integral role in the penetration of active molecule into skin. There are several challenges to formulating topical drugs, which include the biotransformation of the active molecules as they pass through the SC and the physical changes that occur to the vehicle itself when it is applied to the skin. This article will review current and emerging topical antifungal vehicles. PMID:26885798

  11. Topic Model for Graph Mining.

    2015-12-01

    Graph mining has been a popular research area because of its numerous application scenarios. Many unstructured and structured data can be represented as graphs, such as, documents, chemical molecular structures, and images. However, an issue in relation to current research on graphs is that they cannot adequately discover the topics hidden in graph-structured data which can be beneficial for both the unsupervised learning and supervised learning of the graphs. Although topic models have proved to be very successful in discovering latent topics, the standard topic models cannot be directly applied to graph-structured data due to the "bag-of-word" assumption. In this paper, an innovative graph topic model (GTM) is proposed to address this issue, which uses Bernoulli distributions to model the edges between nodes in a graph. It can, therefore, make the edges in a graph contribute to latent topic discovery and further improve the accuracy of the supervised and unsupervised learning of graphs. The experimental results on two different types of graph datasets show that the proposed GTM outperforms the latent Dirichlet allocation on classification by using the unveiled topics of these two models to represent graphs.

    Prednisolone-17-ethylcarbonate-21-propionate (PrEP, Hoe 777) was tested for antiinflammatory activity in various animal models by topical and systemic administration. In those models being indicative of topical efficacy, the potency of PrEP was the same as that of desoximetasone. However, systemic effects after topical administration of PrEP in shaved skin of the dorsum of rats were relatively weak compared with the reference compound. Moreover, there were less systemic glucocorticoid effects after s.c. administration of PrEP than after desoximetasone. Thus, PrEP is obviously a compound with a considerable split of topical and systemic activity, suggesting its testing in man for systemic effects after topical administration. PMID:6981416

    Full Text Available Introduction Understanding of fluid shifts and recognition of the importance of early and appropriate fluid replacement therapy have significantly reduced mortality in the early post burn period. After the bum patient successfully passes the resuscitation period, the burn wound represents the greatest threat to survival. History Since the dawn of civilization, man has been trying to find an agent which would help burn wounds heal, and at the same time, not harm general condition of the injured. It was not until the XX century, after the discovery of antibiotics, when this condition was fulfilled. In 1968, combining silver and sulfadiazine, fox made silver-sulfadiazine, which is a 1% hydro-soluble cream and a superior agent in topical treatment of burns today. Current topical agents None of the topical antimicrobial agents available today, alone or combined, have the characteristics of ideal prophylactic agents, but they eliminate colonization of burn wound, and invasive infections are infrequent. With an excellent spectrum of activity, low toxicity, and ease of application with minimal pain, silver-sulfadiazine is still the most frequently used topical agent. Conclusion The incidence of invasive infections and overall mortality have been significantly reduced after introduction of topical burn wound antimicrobial agents into practice. In most burn patients the drug of choice for prophylaxis is silver sulfadiazine. Other agents may be useful in certain clinical situations.

    1982-06-01

    Systemic absorption of topically applied glucocorticoids in quantities sufficient to replace endogenous production is not uncommon. However, iatrogenic Cushing's syndrome resulting from the use of topical corticosteroids is very rare. Thus the possibility that systemic absorption may cause hyperglucocorticism has been deemphasized and examined only sporadically. We have studied changes in carbohydrate metabolism induced by topical glucocorticoids in a psoriatic patient who had developed Cushing's syndrome from topical desoximetasone (Topicort). The results indicated that (1) fasting hyperglycemia and increased insulin-glucose ratios could be induced within 24 hours of administration of topical glucocorticoids, (2) insulin resistance accompanied abnormal carbohydrate tolerance, and (3) fluctuations in circulating leukocytes paralleled the changes in carbohydrate metabolism. The findings suggest that metabolic indexes of glucocorticoid action action may provide useful parameters for assessing systemic absorption of topical glucocorticoids. glucose relationship as one such index to assess the risk of treatment of extensive chronic skin disease with potent topical glucocorticoids.

  9. Ethical use of topical corticosteroids

    Directory of Open Access Journals (Sweden)

    Abir Saraswat

    2014-01-01

    Full Text Available Dermatologists rely very heavily on corticosteroids for treating many common dermatoses. Concerns about their incorrect use are widely expressed both in lay public and specialist discourse. From the point of view of medical ethics, issues of autonomy, beneficence and non-maleficence are all raised frequently when we prescribe topical corticosteroids to our patients. We need to be aware of situations when conflicts between these issues arise and have a clear thought process about resolving them. This can only be achieved if we have a thorough understanding of the skin disease being treated coupled with expertise in the use of the varied potencies and available dosage forms of topical corticosteroids. A good understanding of human psychology and effective communication is also needed to use these agents optimally.

  20. LECITHINISED MICROEMULSIONS FOR TOPICAL DELIVERY OF TRETINOIN

    Directory of Open Access Journals (Sweden)

    Khanna Surabhi

    2010-12-01

    Full Text Available Tretinoin is indicated for the management of acne, photoaged skin, psoriasis and other skin disorders and also for severe conditions like acute promyelocytic anaemia and squamous cell carcinoma of the skin. The potential of tretinoin in these conditions is limited due to want of a proper delivery vehicle. In order to develop alternate formulations for the topical administration of tretinoin, lecithinsed microemulsions were prepared and evaluated as delivery vehicles. These systems were prepared using phosphate buffer pH 5.5, isopropyl myristate, tween 80 and ethanol. The microemulsions were characterized using TEM. The ability of the system to deliver tretinoin into and through the skin was evaluated in vitro using the skin of laca mice. The in vitro permeation data showed that the novel microemulsions increased tretinoin penetration through the skin; higher flux (33.92 µg / cm2 / hr was obtained with microemulsion formulation and microemulsified gel (31.54 µg / cm2 / hr in comparison to the plain drug solution (22.33 µg / cm2 / hr, plain drug in gel (28.67 µg / cm2 / hr and the marketed preparation (24.28 µg / cm2 / hr. These results were supported by skin retention study and it was noted that the maximum amount retained was with microemulsified gel (96.28 µg / cm2 and non-gel (82.13 µg / cm2 respectively. The other systems; drug in solution, drug in gel (conventional and marketed preparation were able to retain the drug at the level of 32.4 µg/ cm2, 21.54 µg / cm2 and 29.32 µg / cm2 respectively. These results suggest that the studied microemulsions may be appropriate vehicles for topical delivery of tretinoin.

    Full Text Available Background and Purpose: Today no method of topical anesthesia for intravitreal injection administration has been proven to make the patient comfortable yet. We compared the efficacy of topical levobupivacaine 0.75% and proparacaine 0.5% in patients undergoing intravitreal injections. Materials and Methods: A prospective, randomized study comparing two agents for topical anesthesia in intravitreal injections. Ninety-six consecutive patients were enrolled into two groups to receive either topical levobupivacaine 0.75% (n=48 or proparacaine 0.5% (n=48. Patients were asked to score their pain using a visual analog scale (VAS immediately following the injection. The average of these scores was used as the primary outcome. The surgeon performing the procedure scored his perception of the patients′ pain using the Wong-Baker FACES scale. Results: Mean VAS pain scores for two groups were found to be 44.77 ± 16.42 and 34.18 ± 14.83, respectively. Mean VAS pain score in the proparacaine group was significantly lower than that in the levobupivacaine group (P= 0.003. Mean Wong-Baker FACES scores for the two groups were 1.08 ± 0.49 and 1.10 ± 0.30, respectively. There was no statistically significant difference between levobupivacaine and proparacaine groups (P=0.824. Conclusions: Topical proparacaine 0.5% was more effective in preventing pain during intravitreal injections.

  7. On-line Hot Topic Recommendation Using Tolerance Rough Set Based Topic Clustering

    2010-04-01

    Full Text Available In this paper we present our research of online hot topic detection and label extraction method for our hot topic recommendation system. Using a new topical feature selection method, the feature space is compressed suitable for an online system. The tolerance rough set model is used to enriching the small set of topical feature words to a topical approximation space. According to the distance defined on the topical approximation space, the web pages are clustered into groups which will be merged with document overlap. The topic labels are extracted based on the approximation topical space enriched with the useful but high frequency topical words dropped by the clustering process. The experiments show that our method could generate more information abundant classes and more topical class labels, alleviate the topical drift caused by the non-topical and noise words.

    Bubenko, Janis

    A three semester, 60-credit course package in the topic of Administrative Data Processing (ADP), offered in 1966 at Stockholm University (SU) and the Royal Institute of Technology (KTH) is described. The package had an information systems engineering orientation. The first semester focused on datalogical topics, while the second semester focused on the infological topics. The third semester aimed to deepen the students’ knowledge in different parts of ADP and at writing a bachelor thesis. The concluding section of this paper discusses various aspects of the department’s first course effort. The course package led to a concretisation of our discipline and gave our discipline an identity. Our education seemed modern, “just in time”, and well adapted to practical needs. The course package formed the first concrete activity of a group of young teachers and researchers. In a forty-year perspective, these people have further developed the department and the topic to an internationally well-reputed body of knowledge and research. The department has produced more than thirty professors and more than one hundred doctoral degrees.

  9. Human-competitive automatic topic indexing

    CERN Document Server

    Medelyan, Olena

    2009-01-01

    Topic indexing is the task of identifying the main topics covered by a document. These are useful for many purposes: as subject headings in libraries, as keywords in academic publications and as tags on the web. Knowing a document’s topics helps people judge its relevance quickly. However, assigning topics manually is labor intensive. This thesis shows how to generate them automatically in a way that competes with human performance. Three kinds of indexing are investigated: term assignment, a task commonly performed by librarians, who select topics from a controlled vocabulary; tagging, a popular activity of web users, who choose topics freely; and a new method of keyphrase extraction, where topics are equated to Wikipedia article names. A general two-stage algorithm is introduced that first selects candidate topics and then ranks them by significance based on their properties. These properties draw on statistical, semantic, domain-specific and encyclopedic knowledge. They are combined using a machine learn...

This textbook assumes only a basic knowledge of functional analysis, giving the reader a self-contained overview of the ideas and techniques in the development of modern Banach space theory. Special emphasis is placed on the study of the classical Lebesgue spaces Lp (and their sequence space analogues) and spaces of continuous f...

  15. Conclusion from the fifth topic

    International Nuclear Information System (INIS)

    The topic ''mechanics and alteration kinetics of glasses'' is a crucial point for the understanding of the long-term behaviour of nuclear glasses. Kinetic models used in simulation are based on the works made by Grambow who imputes the control of the alteration kinetics of borosilicate glasses to the desorption of the ortho-silica acid produced at the reactive interface. The ensuing kinetics law requires the existence of an equilibrium of the silica at the interface glass/gel and the existence of a linear concentration gradient dissolved in the interstitial gel solution. The role of the gel needs further studies to be well understood. The difficulty lies in the fact that the composition and the structure of the gel varies with time, space (anisotropy) and with the conditions of alteration (temperature, pH, flowrate...). (A.C.)

    2004-01-01

    This book is an often-requested reprint of two classic texts by H. Haken: "Synergetics. An Introduction" and "Advanced Synergetics". Synergetics, an interdisciplinary research program initiated by H. Haken in 1969, deals with the systematic and methodological approach to the rapidly growing field of complexity. Going well beyond qualitative analogies between complex systems in fields as diverse as physics, chemistry, biology, sociology and economics, Synergetics uses tools from theoretical physics and mathematics to construct an unifying framework within which quantitative descriptions of complex, self-organizing systems can be made. This may well explain the timelessness of H. Haken's original texts on this topic, which are now recognized as landmarks in the field of complex systems. They provide both the beginning graduate student and the seasoned researcher with solid knowledge of the basic concepts and mathematical tools. Moreover, they admirably convey the spirit of the pioneering work by the founder of ...

  18. Current Topics in Epilepsy Surgery.

    Science.gov (United States)

    Usui, Naotaka

    2016-05-15

    This article reviews the current topics in the field of epilepsy surgery. Each type of epilepsy is associated with a different set of questions and goals. In mesial temporal lobe epilepsy (MTLE) with hippocampal sclerosis (HS), postoperative seizure outcome is satisfactory. A recent meta-analysis revealed superior seizure outcome after anterior temporal lobectomy compared with selective amygdalohippocampectomy; in terms of cognitive outcome; however, amygdalohippocampectomy may be beneficial. In temporal lobe epilepsy with normal magnetic resonance imaging (MRI), postoperative seizure outcome is not as favorable as it is in MTLE with HS; further improvement of seizure outcome in these cases is necessary. Focal cortical dysplasia is the most common substrate in intractable neocortical epilepsy, especially in children, as well as in MRI-invisible neocortical epilepsy. Postoperative seizure-free outcome is approximately 60-70%; further diagnostic and therapeutic improvement is required. Regarding diagnostic methodology, an important topic currently under discussion is wideband electroencephalogram (EEG) analysis. Although high-frequency oscillations and ictal direct current shifts are considered important markers of epileptogenic zones, the clinical significance of these findings should be clarified further. Regarding alternatives to surgery, neuromodulation therapy can be an option for patients who are not amenable to resective surgery. In addition to vagus nerve stimulation, intracranial stimulation such as responsive neurostimulation or anterior thalamic stimulation is reported to have a modest seizure suppression effect. Postoperative management such as rehabilitation and antiepileptic drug (AED) management is important. It has been reported that postoperative rehabilitation improves postoperative employment status. Pre- and post-operative comprehensive care is mandatory for postoperative improvement of quality of life. PMID:26984452

  19. Current topics in radiation measurements

    International Nuclear Information System (INIS)

    Current research topics in radiation measurements will be shown in this presentation. Applications of radiation measurements have grown with the development of radiation sources and new measurement techniques. Recent new developments in this field are briefly introduced. Optical techniques such as lasers and fiber optics, which are widely used in an optical communication field, are successfully applied to radiation measurements. Micro-fabrication techniques and the photolithography technique are indispensable for semiconductor or even gas detectors. Complicated analog signal processing is being simplified by the use of fast computation techniques available in digital chips. Cryogenic X-ray detectors are making a great progress in the energy resolution. Some of the current research topics found in the recent journals and international symposiums are as follows: the development of room temperature semiconductor radiation detectors like CdZnTe and SiC, new signal processing methods such as coplanar grid unipolar charge sensing, medical γ-ray imaging, the development of cryogenic X-ray detectors such as STJs (Superconducting Tunnel Junction) and TES (Transition Edge Sensor) microcalorimeters, micromachined gas proportional counters like MSGC/MGC/GEM, new detection system which requires both the energy and spatial resolutions, the search of longer wavelength scintillators, development of new fast scintillators such as LSO/YAP/LuAP, new digital waveform processing based on fast digitizing technique, etc. Current developments are especially focused on the increase of the information derived from the detector and the improvement in the resolution. One of the other directions of the development is toward the microscopic visualization of the radiation. Such an approach must solve many technological difficulties both in fabrication of the detectors and even in the detection scheme, however, we might proceed to open a new phase of radiation measurements soon.

  2. Multilingual Topic Models for Unaligned Text

    CERN Document Server

    Boyd-Graber, Jordan

    2012-01-01

    We develop the multilingual topic model for unaligned text (MuTo), a probabilistic model of text that is designed to analyze corpora composed of documents in two languages. From these documents, MuTo uses stochastic EM to simultaneously discover both a matching between the languages and multilingual latent topics. We demonstrate that MuTo is able to find shared topics on real-world multilingual corpora, successfully pairing related documents across languages. MuTo provides a new framework for creating multilingual topic models without needing carefully curated parallel corpora and allows applications built using the topic model formalism to be applied to a much wider class of corpora.

    Twitter is an extremely high volume platform for user generated contributions regarding any topic. The wealth of content created at real-time in massive quantities calls for automated approaches to identify the topics of the contributions. Such topics can be utilized in numerous ways, such as public opinion mining, marketing, entertainment, and disaster management. Towards this end, approaches to relate single or partial posts to knowledge base items have been proposed. However, in microblogging systems like Twitter, topics emerge from the culmination of a large number of contributions. Therefore, identifying topics based on collections of posts, where individual posts contribute to some aspect of the greater topic is necessary. Models, such as Latent Dirichlet Allocation (LDA), propose algorithms for relating collections of posts to sets of keywords that represent underlying topics. In these approaches, figuring out what the specific topic(s) the keyword sets represent remains as a separate task. Another issue in topic detection is the scope, which is often limited to specific domain, such as health. This work proposes an approach for identifying domain-independent specific topics related to sets of posts. In this approach, individual posts are processed and then aggregated to identify key tokens, which are then mapped to specific topics. Wikipedia article titles are selected to represent topics, since they are up to date, user-generated, sophisticated articles that span topics of human interest. This paper describes the proposed approach, a prototype implementation, and a case study based on data gathered during the heavily contributed periods corresponding to the four US election debates in 2012. The manually evaluated results (0.96 precision) and other observations from the study are discussed in detail. PMID:26991442

  11. Two Topics In String Theory

    CERN Document Server

    Cheung, Y E

    2000-01-01

    We study two topics in string theory: consistency of D- branes and their intersections in topologically nontrivial background, and Noncommutative Geometry and “Little String Theories.” When a D-brane wraps around a cycle of a curved manifold, the nontrivial topology of its normal bundle can induce chiral asymmetry in its worldvolume theory. We obtain the general form of the resulting anomalies for D-branes and their intersections. They are not cancelled among themselves, and the standard inflow mechanism does not apply at first sight because of their apparent lack of factorizability and the apparent vanishing of the corresponding inflow. We show, however, that after taking into consideration the effects of the twisting of the normal bundles, the anomalies can be transformed into factorized forms and precisely cancelled by finite inflow from the Chern-Simons actions for the D-branes as long as the latter are well defined. Such twisting of the normal bundle is shown to induce Ramond-Ramond c...

    International Nuclear Information System (INIS)

    The growth of the Internet has provided a unique opportunity to expand research collaborations between industry, universities, and the national laboratories. The Virtual Robotics Laboratory (VRL) is an innovative program at Oak Ridge National Laboratory (ORNL) that is focusing on the issues related to collaborative research through controlled access of laboratory equipment using the World Wide Web. The VRL will provide different levels of access to selected ORNL laboratory secondary education programs. In the past, the ORNL Robotics and Process Systems Division has developed state-of-the-art robotic systems for the Army, NASA, Department of Energy, Department of Defense, as well as many other clients. After proof of concept, many of these systems sit dormant in the laboratories. This is not out of completion of all possible research topics. but from completion of contracts and generation of new programs. In the past, a number of visiting professors have used this equipment for their own research. However, this requires that the professor, and possibly his/her students, spend extended periods at the laboratory facility. In addition, only a very exclusive group of faculty can gain access to the laboratory and hardware. The VRL is a tool that enables extended collaborative efforts without regard to geographic limitations

    2013-05-01

    This Topical Report addresses accomplishments achieved during Phase 2a of the SkyMine® Carbon Mineralization Pilot Project. The primary objectives of this project are to design, construct, and operate a system to capture CO2 from a slipstream of flue gas from a commercial coal-fired cement kiln, convert that CO2 to products having commercial value (i.e., beneficial use), show the economic viability of the CO2 capture and conversion process, and thereby advance the technology to the point of readiness for commercial scale demonstration and proliferation. The overall process is carbon negative, resulting in mineralization of CO2 that would otherwise be released into the atmosphere. The project will also substantiate market opportunities for the technology by sales of chemicals into existing markets, and identify opportunities to improve technology performance and reduce costs at the commercial scale. The project is being conducted in two phases. The primary objectives of Phase 1 were to elaborate proven SkyMine® process chemistry to commercial pilot-scale operation and complete the preliminary design for the pilot plant to be built and operated in Phase 2, complete a NEPA evaluation, and develop a comprehensive carbon life cycle analysis. The objective of the current Phase (2a) is to complete the detailed design of the pilot plant to be built in Phase 2b.

    2002-07-01

    As main current topics in pediatric nutrition we have considered the results of the continuing research on the long term consequences of fetal malnutrition and intra-uterine growth retardation with the concept of metabolic imprinting leading to chronic disease in adulthood, the progresses of knowledge in the fields of iron metabolism and regulatory mechanisms of satiety, hunger and energetic balance, a better determination of recommended docosahexanoic and arachidonic acids intake in the first months of life for premature and term infants, and the studies on probiotics and prebiotics utilization for preventive and curative purposes. The concerns about vitamin D insufficiency in France have markedly decreased with the generalization ten years ago of cholecalciferol supplementation of infant formula, and more recently the authorization of dairy products supplementation. On the contrary the problem of iron deficiency in young children remains, as well as two major nutritional concerns: the very low percentage of breast-fed infants and the dramatic increase of childhood obesity which affects presently 14% of 10 year old children versus 5% in 1980.

    Full Text Available With changing times various newer topical agents are introduced in the field of dermatology. Tacrolimus and pimecrolimus are immunisuppressants, which are effective topically and are tried in the management of atopic dermatitis as well as other disorders including allergic contact dermatitis, atrophic lichen planus, pyoderma gangrenosum. Imiquimod, an immune response modifier, is presently in use for genital warts but has potentials as anti- tumour agent and in various other dermatological conditions when used topically. Tazarotene is a newer addition to the list of topical reginoids, which is effective in psoriasis and has better effect in combination with calcipotriene, phototherapy and topical costicosteroids. Tazarotene and adapelene are also effective in inflammatory acne. Calcipotriol, a vitamin D analogue has been introduced as a topical agent in the treatment of psoriasis. Steroid components are also developed recently which will be devoid of the side effects but having adequate anti-inflammatory effect. Topical photodynamic therapy has also a wide range of use in dermatology. Newer topical agents including cidofovir, capsaicin, topical sensitizers, topical antifungal agents for onychomycosis are also of use in clinical practice. Other promising developments include skin substitutes and growth factors for wound care.

  18. Selected topics of fluid mechanics

    the Euler, Froude, Reynolds, Weber, and Cauchy numbers are defined as essential tools for interpreting and using experimental data. The derivations of the energy and momentum equations are treated in detail. One-dimensional equations for steady nonuniform flow are developed, and the restrictions applicable to the equations are emphasized. Conditions of uniform and gradually varied flow are discussed, and the origin of the Chezy equation is examined in relation to both the energy and the momentum equations. The inadequacy of all uniform-flow equations as a means of describing gradually varied flow is explained. Thus, one of the definitive problems of river hydraulics is analyzed in the light of present knowledge. This report is the outgrowth of a series of short schools conducted during the spring and summer of 1953 for engineers of the Surface Water Branch, Water Resources Division, U. S. Geological Survey. The topics considered are essentially the same as the topics selected for inclusion in the schools. However, in order that they might serve better as a guide and outline for informal study, the arrangement of the writer's original lecture notes has been considerably altered. The purpose of the report, like the purpose of the schools which inspired it, is to build a simple but strong framework of the fundamentals of fluid mechanics. It is believed that this framework is capable of supporting a detailed analysis of most of the practical problems met by the engineers of the Geological Survey. It is hoped that the least accomplishment of this work will be to inspire the reader with the confidence and desire to read more of the recent and current technical literature of modern fluid mechanics.

  19. Topics in topological band systems

    Science.gov (United States)

    Huang, Zhoushen

    The discovery of integer quantum Hall effect and its subsequent theoretical formulation heralded a new paradigm of thinking in condensed matter physics, which has by now blossomed into the rapidly growing field of topological phases. In this work we investigate several mutually related topics in the framework of topological band theory. In Chapter 2, we study solutions to boundary states on a lattice and see how they are related to the bulk topology. To elicit a real space manifestation of the non-trivial topology, the presence of a physical edge is not strictly necessary. We study two other possibilities, namely the entanglement spectrum associated with an imaginary spatial boundary, and the localization centers of Wannier functions, in Chapters 3,4, and 5. Topological classification through discrete indices is so far possible only for systems described by pure quantum states---in the existing scheme, quantization is lost for systems in mixed states. In Chapter 6, we present a program through which discrete topological indices can be defined for topological band systems at finite temperature, based on Uhlmann's parallel transport of density matrices. The potential of topologocal insulators in realistic applications lies in the existence of Dirac nodes on its surface spectrum. Dirac physics, however, is not exclusive to TI surfaces. In a recently discovered class of materials known as Weyl semimetals, energy nodes which emit linear dispersions also occur in the bulk material. In Chapter 7, we study the possibility of resonance states induced by localized impurities near the nodal energy in Weyl semimetals, which will help us in understanding the stability of density-of-state suppression at the energy nodes. Finally, in Chapter 8, we apply the topological characterization developed for noninteracting particles to a class of interacting spin models in 3D, which are generalizations of Kitaev's honeycomb model, and identify several exotic quantum phases such as spin

    Atopic dermatitis is a common, chronic, relapsing inflammatory skin disease frequently affecting infants and children. The worldwide prevalence of atopic dermatitis is estimated to be 5-20% of the paediatric population. First-line therapy has generally consisted of dry skin care, avoidance of triggers, application of topical corticosteroids, and administration of antihistamines and oral antibacterials. Topical corticosteroids improve the lesions of atopic dermatitis; however, concern on the p...

  2. Tracking topic birth and death in LDA.

    Energy Technology Data Exchange (ETDEWEB)

    Wilson, Andrew T.; Robinson, David Gerald

    2011-09-01

    Most topic modeling algorithms that address the evolution of documents over time use the same number of topics at all times. This obscures the common occurrence in the data where new subjects arise and old ones diminish or disappear entirely. We propose an algorithm to model the birth and death of topics within an LDA-like framework. The user selects an initial number of topics, after which new topics are created and retired without further supervision. Our approach also accommodates many of the acceleration and parallelization schemes developed in recent years for standard LDA. In recent years, topic modeling algorithms such as latent semantic analysis (LSA)[17], latent Dirichlet allocation (LDA)[10] and their descendants have offered a powerful way to explore and interrogate corpora far too large for any human to grasp without assistance. Using such algorithms we are able to search for similar documents, model and track the volume of topics over time, search for correlated topics or model them with a hierarchy. Most of these algorithms are intended for use with static corpora where the number of documents and the size of the vocabulary are known in advance. Moreover, almost all current topic modeling algorithms fix the number of topics as one of the input parameters and keep it fixed across the entire corpus. While this is appropriate for static corpora, it becomes a serious handicap when analyzing time-varying data sets where topics come and go as a matter of course. This is doubly true for online algorithms that may not have the option of revising earlier results in light of new data. To be sure, these algorithms will account for changing data one way or another, but without the ability to adapt to structural changes such as entirely new topics they may do so in counterintuitive ways.

    This article focuses on nonprescription home-use topical treatment technologies for the aging face and is intended to serve as a guide for the core cosmeceutical technologies currently used and to help educate and assist the selection of topical antiaging products by the professional staff and their patients. Antiaging topical treatments for patient home use should be nonirritating, compatible with the patient skin type, effective, and complementary to surgical and minimally invasive office procedures, and aesthetically elegant. New topical antiaging technologies, formulated as monotherapy or as combinations with well-known cosmeceuticals, should present adequate clinical studies to support their selection for use.

    2015-04-01

    The treatment of rosacea is challenging because several pathophysiologic processes may be involved, including neurovascular dysregulation and alterations in innate immune status. Demodex mites may play a role in the latter mechanism. Topical ivermectin is a new therapeutic modality which demonstrates antiparasitic and anti-inflammatory properties. This article reviews published evidence related to the efficacy and safety of topical ivermectin. PubMed was utilized to search for key words "topical ivermectin", "ivermectin cream" and "rosacea". Three clinical trials were found that studied topical ivermectin as a treatment option for rosacea. Ivermectin was effective, safe and well tolerated. PMID:26020066

    As described in this article, there are many advances in topical and local anesthesia. Topical and local anesthetics have played a great role in dentistry in alleviating the fears of patients, eliminating pain, and providing pain control. Many invasive procedures would not be performed without the use and advances of topical/local anesthetics. The modern-day dentist has the responsibility of knowing the variety of products on the market and should have at least references to access before, during, and after treatment. This practice ensures proper care with topical and local anesthetics for the masses of patients entering dental offices worldwide. PMID:27040295

    Data structures and data base management systems are common tools employed to deal with the administrative information of a university. An understanding of these topics is needed by a much wider audience, ranging from those interested in computer aided design and manufacturing to those using microcomputers. These tools are becoming increasingly valuable to academic programs as they develop comprehensive computer support systems. The wide use of these tools relies upon the relational data model as a foundation. Experience with the use of the IPAD RIM5.0 program is described.

    -subsidization, the largest state-owned firm was split to form Statkraft SF, Norway's largest generation company, and Statnett SF, the major transmission company. Statnett is also the system operator of the entire Norwegian power system. Many distribution companies, usually publicly owned, are still part of vertically integrated companies, but there is strict separation of the financial accounts for transmission/distribution and generation/marketing. Trading is accomplished through several channels. The largest organized market is the common Norwegian-Swedish pool, NordPool. NordPool ASA is owned by Statnett Marked (which is a subsidiary of Statnett) and the Swedish grid-company, Svenska Kraftnaet. NordPool also supports the Finnish and Danish markets, thus through cooperation with the grid-companies of Denmark (Eltra) and Finland (Fingrid), locational markets are provided in these countries as well. Unlike England and Wales, only part of actual production is traded on this market. In addition, independent brokers offer various energy-contracts and facilitate bilateral contracts. In 1998 22% of the energy was traded on the hourly day-ahead (spot) market of NordPool. NordPool also organizes a forward and futures market and settles contracts from the regulation market organized by Statnett. The regulation market is a realtime market used to settle imbalances in real time. In total, close to 30% of the energy traded is organized through NordPool, and this share is increasing year by year. The efficiency of the market is heavily affected by the operation and pricing of the transmission system, and the topic of this thesis concerns the interaction of the transmission network and the energy markets. Throughout, the findings are illustrated by means of simple examples. This is to enhance readability and intuition. To start with, chapter 2 is devoted to power flow models, whereas chapter 3 provides an overview of models developed to efficiently coordinate the allocation of transmission

  18. Correlated Topic Model for Web Services Ranking

    2013-07-01

    Full Text Available With the increasing number of published Web services providing similar functionalities, it’s very tedious for a service consumer to make decision to select the appropriate one according to her/his needs. In this paper, we explore several probabilistic topic models: Probabilistic Latent Semantic Analysis (PLSA, Latent Dirichlet Allocation (LDA and Correlated Topic Model (CTM to extract latent factors from web service descriptions. In our approach, topic models are used as efficient dimension reduction techniques, which are able to capture semantic relationships between word-topic and topic-service interpreted in terms of probability distributions. To address the limitation of keywords-based queries, we represent web service description as a vector space and we introduce a new approach for discovering and ranking web services using latent factors. In our experiment, we evaluated our Service Discovery and Ranking approach by calculating the precision (P@n and normalized discounted cumulative gain (NDCGn.

  19. Topic maps for custom viewing of data

    CERN Document Server

    Mahabal, A A; Williams, R E; Brunner, R J

    2002-01-01

    A Topic Map is a structured network of hyperlinks that points into an information pool. Topic Maps have an existence independent of the information pool and hence different Topic Maps can form different layers above the same information pool and provide us with different views of it. We explore the use of Topic Maps with the Unified Column Descriptor (UCD) scheme developed in the frame of the ESO-CDS data mining project. UCD, with its multi-tier hierarchical structure, categorizes parameters reported in tables and catalogs. By using Topic Maps we show how columns from different catalogs with similar but not identical descriptions could be combined. A direct application for the Virtual Observatory community is that of merging catalogs in order to generate customized views of data.

    Networked computers are expanding more and more around the world, and digital social networks becoming of great importance for many people's work and leisure. This paper mainly focused on discovering the topic of exchanging information in digital social network. In brief, our method is to use a hierarchical dictionary of related topics and words that mapped to a graph. Then, with comparing the extracted keywords from the context of social network with graph nodes, probability of relation between context and desired topics will be computed. This model can be used in many applications such as advertising, viral marketing and high-risk group detection.

  7. Control of pain with topical plant medicines

    Institute of Scientific and Technical Information of China (English)

    James; David; Adams; Jr.; Xiaogang; Wang

    2015-01-01

    Pain is normally treated with oral nonsteroidal anti-inflammatory agents and opioids. These drugs are dangerous and are responsible for many hospitalizations and deaths. It is much safer to use topical preparations made from plants to treat pain, even severe pain. Topical preparations must contain compounds that penetrate the skin, inhibit pain receptors such as transient receptor potential cation channels and cyclooxygenase-2, to relieve pain. Inhibition of pain in the skin disrupts the pain cycle and avoids exposure of internal organs to large amounts of toxic compounds. Use of topical pain relievers has the potential to save many lives, decrease medical costs and improve therapy.

    Full Text Available The activity of administrative bodies includes big numbers of various acts and actions, through which the will of public administration is formed. The will of public administration bodies, expressed in administrative individual and normative acts, in administrative contracts and real acts, finds its reflection in the Constitution, laws and other provisions of legal character. All this activity is not inerrant and therefore, it is not uncontrollable. The supervision of executive activity is subject to political control of administrative acts through authorities designated for this purpose, as well as internal control and the judicial control. The institution of judicial control of administrative acts and actions appears as very important and widely treated in the legal doctrine. The protection of constitutional and legal rights of private persons is accomplished by subjecting administrative activity both to internal administrative control, as well as to the judicial control in accordance with legal provisions. The judicial control of administrative acts represents a constitutional guarantee for citizens to protect their rights through public and fair trial by an independent and impartial court. In this way, the Constitution empowers the common administrative court that invalidates an action or administrative act, but not all administrative acts may be subject to administrative dispute, with the exception of cases against which the administrative conflict cannot be carried out (negative enumeration.

    2014-01-01

    Streams of user-generated content in social media exhibit patterns of collective attention across diverse topics, with temporal structures determined both by exogenous factors and endogenous factors. Teasing apart different topics and resolving their individual, concurrent, activity timelines is a key challenge in extracting knowledge from microblog streams. Facing this challenge requires the use of methods that expose latent signals by using term correlations across posts and over time. Here we focus on content posted to Twitter during the London 2012 Olympics, for which a detailed schedule of events is independently available and can be used for reference. We mine the temporal structure of topical activity by using two methods based on non-negative matrix factorization. We show that for events in the Olympics schedule that can be semantically matched to Twitter topics, the extracted Twitter activity timeline closely matches the known timeline from the schedule. Our results show that, given appropriate techn...

  15. A Survey On Interactivity in Topic Models

    2016-04-01

    Full Text Available Trying to make sense and gain deeper insight from large sets of data is becoming a task very central to computer science in general. Topic models, capable of uncovering the semantic themes pervading through large collections of documents, have seen a surge in popularity in recent years. However, topic models are high level statistical tools; their output is given in terms of probability distributions, suited neither for simple interpretation nor deep analysis. Interpreting the fitted topic models in an intuitive manner requires visual and interactive tools. Additionally, some measure of human interaction is typically required for refining the output offered by such models. In the research, this area remains relatively unexplored – only recently has this aspect been receiving more attention. In this paper, the literature is surveyed as it pertains to interactivity and visualisation within the context of topic models, with the goal of finding current research trends in this area.

    Full Text Available Christos E Lampropoulos, David P D’CruzLupus Research Unit, Rayne Institute, St. Thomas’ Hospital, London, UKAbstract: Cutaneous lupus erythematosus (CLE encompasses a variety of lesions that may be refractory to systemic or topical agents. Discoid lupus erythematosus (DLE and subacute cutaneous lupus erythematosus (SCLE are the most common lesions in clinical practice. The topical calcineurin inhibitors, tacrolimus and pimecrolimus, have been used to treat resistant cutaneous lupus since 2002 and inhibit the proliferation and activation of T-cells and suppress immune-mediated cutaneous inflammation. This article reviews the mechanism of action, efficacy, adverse effects, and the recent concern about their possible carcinogenic effect. Although the total number of patients is small and there is only one relevant randomized controlled study, the data are encouraging. Many patients, previously resistant to systemic agents or topical steroids, improved after four weeks of treatment. DLE and SCLE lesions were less responsive, reflecting the chronicity of the lesions, although more than 50% of patients still showed improvement. Topical calcineurin inhibitors may be a safe and effective alternative to topical steroids for CLE although the only approved indication is for atopic dermatitis.Keywords: tacrolimus, pimecrolimus, cutaneous lupus erythematosus, topical calcineurin inhibitors

  11. Satisfaction level with topical versus peribulbar anesthesia experienced by same patient for phacoemulsification

    Directory of Open Access Journals (Sweden)

    Nauman Ahmad

    2012-01-01

    Full Text Available Background: Various studies have assessed patient satisfaction with topical versus peribulbar anesthesia with conflicting results. Aim of study was to determine satisfaction level in same patient who gets topical anesthesia in one eye and peribulbar block in another eye. We propose that evaluation of various indicators of patient satisfaction will enable better selection of cases for topical anesthesia in the future. Methods: Eighty patients scheduled for phacoemulsification were enrolled in prospective, randomized, double-blind study. Each patient scheduled twice for one eye under topical anesthesia and other in peribulbar block. Pain, discomfort and pressure during application of local anesthetic, during phacoemulsification and at 2 hours after procedure were assessed on standard scales. Before discharge patient satisfaction level was checked with Iowa satisfaction with anesthesia scale (ISAS. The Student′s t-test was used to determine the significance of IOWA score in both groups. P<0.05 was considered significant. Results: Feeling of pain, pressure and discomfort scores during administration of topical anesthesia were all significantly lower compared to peribulbar anesthesia (P=0.004, 0.000, 0.002, respectively. In contrast, intraoperative scores were significantly higher in the topical anesthesia group compared to peribulbar anesthesia (P=0.022, 0.000, 0.000, respectively. Patient satisfaction measured with ISAS shows that peribulbar anesthesia with P=0.000 is strongly significant. Conclusion: Peribulbar anesthesia provided significantly better patient satisfaction in comparison with topical anesthesia when used for cataract surgery.

    Full Text Available Topic models provide a convenient way to analyze large of unclassified text. A topic contains a cluster of words that frequently occur together. A topic modeling can connect words with similar meanings and distinguish between uses of words with multiple meanings. This paper provides two categories that can be under the field of topic modeling. First one discusses the area of methods of topic modeling, which has four methods that can be considerable under this category. These methods are Latent semantic analysis (LSA, Probabilistic latent semantic analysis (PLSA, Latent Dirichlet allocation (LDA, and Correlated topic model (CTM. The second category is called topic evolution models, which model topics by considering an important factor time. In the second category, different models are discussed, such as topic over time (TOT, dynamic topic models (DTM, multiscale topic tomography, dynamic topic correlation detection, detecting topic evolution in scientific literature, etc.

In order to infer the structure of the topics in the field, the data of the papers published in the Journal of Informetricsand Scientometrics during 2007 to 2013 are retrieved from the database of the Web of Science as input of the approach of topic modeling. The results of this study show that when the number of topics was set to 10, the topic model has the smallest perplexity. Although data scopes and analysis methodsare different to previous studies, the generating topics of this study are consistent with those results produced by analyses of experts. Empirical case studies and measurements of bibliometric indicators were concerned important in every year during the whole analytic period, and the field was increasing stability. Both the two core journals broadly paid more attention to all of the topics in the field of Informetrics. The Journal of Informetricsput particular emphasis on construction and applications ofbibliometric indicators and Scientometrics focused on the evaluation and the factors of productivity of countries, institutions, domains, and journals.

    Full Text Available Background: Considering safe treatment modalities for children with vitiligo, search for newer therapeutic agents continues. Hence, new immunomodulatory agents such as calcineurinantagonists, frequently referred to as topical immunomodulators (TIMs have recently been introduced as new promising tools to treat acquired hypopigmentary disorders. Tacrolimus is safe in treating children due to lack of skin atrophy and less data are available on effect of topical tacrolimus on vitiligo. Objective: To see the effect of topical tacrolimus on vitiligo in children. Materials and Methods: This prospective study was done in outpatient department of Dermatology and Venereology, Chittagong Medical College Hospital (CMCH, Bangladesh. Clinically diagnosed vitiligo patients of up to 12 years age visiting Skin & VD OPD, CMCH during study period were the study population (total 30. The study was carried out from November 2007 to April 2008. Results: A total of 30 patients, 13 (43.33% males and 17 (56.66% females with focal, segmental or generalized vitiligo were studied. Seventy percent of study subjects were from 7–12 years of age. Topical tacrolimus 0.03% ointment was administered twice daily for 12 weeks to each patient. Repigmentation was complete (>75% in 43.33% cases (13/30, was moderate (50–75% in 33.33% (10/30, mild (<50% in 13.33% (4/30. Clinical adverse effects were noted in 6.67% (2/30 of cases where pruritus was in 3.33% (1/30 and burning in 3.33% (1/30. None of the reactions was severe, all were mild and well-tolerated and most occurred within the first month of initiation of treatment and resolved with continued use of drug and completely cured after the treatment completed. Nobody had to discontinue the therapy for side effects. Conclusion: In conclusion, tacrolimus ointment may be a rapidly efficacious and safe option for the treatment of vitiligo in children. The ease of topical self-administration with minimal side effects makes this novel

    2006-09-01

    Exposure to ultraviolet radiation is known to cause many adverse side effects by inducing the tissue to produce reactive oxygen species. By inhibiting these mediators, administration ofantioxidants might be the strategy to reduce UVA-induced skin reaction such as tissue damage and inflammation. However the present study showed that administration of topical 10% vitamin C derivative (VC-PMG) and topical 5% vitamin E has no effect in terms ofprevention or treatment of UVA suntan skin in 20 volunteers. Prior to 30 Joules UVA exposures, they were asked to apply both agents twice daily for 3 days. Then, the melanin index was measured immediately after irradiation by using the Maxemeter which was insignificant at the 95% level of confidence compared with the placebo. After continuing the cream application for 12 weeks, there were also no bleaching effects observed after 2, 4, 6, 8, 10 and 12 weeks compared to the placebo. PMID:17722304

  5. Learning Topic Models by Belief Propagation

    Zeng, Jia; Liu, Jiming

    2011-01-01

    Latent Dirichlet allocation (LDA) is an important class of hierarchical Bayesian models for probabilistic topic modeling, which attracts worldwide interests and touches many important applications in text mining, computer vision and computational biology. This paper proposes a novel tree-structured factor graph representation for LDA within the Markov random field (MRF) framework, which enables the classic belief propagation (BP) algorithm for exact inference and parameter estimation. Although two commonly-used approximation inference methods, such as variational Bayes (VB) and collapsed Gibbs sampling (GS), have gained great successes in learning LDA, the proposed BP is competitive in both speed and accuracy validated by encouraging experimental results on four large-scale document data sets. Furthermore, the BP algorithm has the potential to become a generic learning scheme for variants of LDA-based topic models. To this end, we show how to learn two typical variants of LDA-based topic models, such as autho...

    Full Text Available In this lesson you will first learn what topic modeling is and why you might want to employ it in your research. You will then learn how to install and work with the MALLET natural language processing toolkit to do so. MALLET involves modifying an environment variable (essentially, setting up a short-cut so that your computer always knows where to find the MALLET program and working with the command line (ie, by typing in commands manually, rather than clicking on icons or menus. We will run the topic modeller on some example files, and look at the kinds of outputs that MALLET installed. This will give us a good idea of how it can be used on a corpus of texts to identify topics found in the documents without reading them individually.

    The treatment of perniosis is largely inadequate. The success rate of 0.2% nitroglycerine ointment is demonstrated in the present series. Twenty-two patients clinically diagnosed with severe perniosis were prescribed the topical vasodilator nitroglycerine. Digital photography and patient self-report of the clinical appearance, degree of irritation, and pain and soreness of the lesions were assessed on a 3-point scale to assess therapeutic response. A total of 18 of the 22 patients had regression of the lesions within the first week of treatment and complete regression in 2 weeks. Of these patients, 2 who experienced a relapse were successfully treated with another course of topical nitroglycerine. Two of 22 patients had regression of the lesions during the second week and complete regression in another week. Response was delayed in patients with a longer duration of disease. Topical 0.2% nitroglycerine ointment may be a promising alternative treatment option in perniosis. PMID:26380502

    Vitamin D analogues can reduce TGF-β pro-fibrotic signaling in dermal fibroblasts, but they may also induce a potentially pro-fibrotic thymic stromal lymphopoietin (TSLP)-dependent Th2 cytokine local response. We have analyzed the net effect of topical vitamin D analogue calcipotriol (CPT) on the cytokine profile and the development of fibrosis in experimental model of bleomycin-induced fibrosis. Mice were simultaneously treated with topical CPT or vehicle cream and skin fibrosis was measured by collagen deposition, Masson's trichrome staining and hydroxyproline content. Cytokine and TSLP gene expression was evaluated by quantitative RT-PCR. We showed that in bleomycin injected skin, CPT administration significantly enhanced TSLP and IL-13 gene expression, but did not modify the expression of other cytokines. Skin fibrosis and hydroxyproline content were significantly reduced in CPT compared to vehicle-treated mice. In normal skin, topical administration of CPT lacked a direct pro-fibrotic effect. Our results demonstrate that topical CPT superinduces the expression of the TSLP/IL-13 Th2 axis in fibrotic skin, but it has a net anti-fibrotic effect. These data support the therapeutic use of topical vitamin D analogues for skin fibrosis. PMID:24788893

    Non-steroid anti-inflammatory drugs (NSAIDs), such as etofenamate, are among the most prescribed drugs used for their analgesic, anti-rheumatic, antipyretic and anti-inflammatory properties. Topical formulations have the main advantage of targeted delivery. However, drugs must overcome the skin due to its role as a physical and chemical barrier against the penetration of chemicals and microorganisms. This barrier must be altered to allow the permeation of drugs at a suitable rate to the desired site of activity. Permeation modulators can intercalate the skin outer layers causing structure disruption, opening an energetically favourable route for the drug to diffuse through. The aim of this work was the development of hydroalcoholic gels containing 5.0% (w/w) of etofenamate for topical administration with anti-inflammatory activity and enhanced drug delivery. The physical and chemical characterization, in vitro release and permeation studies and in vivo anti-inflammatory activity were assessed. The gel with 30% ethanol showed in vivo anti-inflammatory activity with suitable physical chemical and microbiologic characteristics. In vitro release and permeation studies revealed that the different amounts of ethanol used influenced the release profiles of etofenamate. Moreover, it was demonstrated that this formulation is an adequate vehicle for the etofenamate skin permeation. PMID:24798887

  15. Topical Administration of Acylated Homoserine Lactone Improves Epithelialization of Cutaneous Wounds in Hyperglycaemic Rats.

    Directory of Open Access Journals (Sweden)

    Lijuan Huang

    Full Text Available Clinicians often experience delayed epithelialization in diabetic patients, for which a high glucose condition is one of the causes. However, the mechanisms underlying delayed wound closure have not been fully elucidated, and effective treatments to enhance epithelialization in patients with hyperglycaemia have not been established. Here we propose a new reagent, acylated homoserine lactone (AHL, to improve the delayed epithelialization due to the disordered formation of a basement membrane of epidermis in hyperglycaemic rats. Acute hyperglycaemia was induced by streptozotocin injection in this experiment. Full thickness wounds were created on the flanks of hyperglycaemic or control rats. Histochemical and immunohistochemical analyses were performed to identify hyperglycaemia-specific abnormalities in epidermal regeneration by comparison between groups. We then examined the effects of AHL on delayed epithelialization in hyperglycaemic rats. Histological analysis showed the significantly shorter epithelializing tissue (P < 0.05, abnormal structure of basement membrane (fragmentation and immaturity, and hypo- and hyperproliferation of basal keratinocytes in hyperglycaemic rats. Treating the wound with AHL resulted in the decreased abnormalities of basement membrane, normal distribution of proliferating epidermal keratinocytes, and significantly promoted epithelialization (P < 0.05 in hyperglycemic rats, suggesting the improving effects of AHL on abnormal epithelialization due to hyperglycemia.

    Two water in oil emulsions composed by eudermic ingredients as glycerin, cocoa butter, almond oil and a variety of lipids, were enriched respectively with milk thistle dry extract (MT) or with a binary complex composed by MT and hydroxypropyl-β-cyclodextrin (HP) (1:4 w/w) correspondent to 1% (w/w) in sylimarine in order to obtain two different emulsions designed for the skin delivery and determine influence of hydroxypropyl-β-cyclodextrin on the extract delivery and permeation. Uv-vis spectrophotometric analyses demonstrated that phytocomplex formation influences the finding of MT after the complexation process and the in vitro antioxidant activity. Further in vitro and ex vivo experiments demonstrated that the penetration capability of MT from formulations is strictly influenced by the phytocomplex able to control MT permeation; moreover phytocomplex increases flavonoids stability during the in vitro tests. Additionally, in vivo studies showed that the penetration into the stratum corneum of the active ingredients is effectively achieved by the phytocomplex formation, in fact about 80% of MT is absorbed by the skin along 1h despite the 30% of MT not complexed absorbed during the same period.

  17. Photodynamic therapy with topical phthalocyanine formulation on intradermally transplanted EMT-6 tumors in BALB/c mice

    International Nuclear Information System (INIS)

    Topical application of photosensitizers is considered an alternative approach to the PhotoDynamic Therapy of skin tumors, reducing the risk of systemic side effects such as skin photosensitivity. Basal cell carcinoma lesions in patients have successfully been eradicated by red light after topical administration of tetraphenyl-porphine-sulfonate or 5-Amino-Levulinic Acid the latter inducing in situ protoporphyrin IX biosynthesis. PDT with topically applied Phthalo-cyanines has not yet been reported although these dyes have been recognized as promising second generation photosensitizers. Their strong absorption above 650 nm allows use of far red therapeutic light, providing greater tissue penetration. Naphthalo-cyanines exhibit even further red shifting of the absorption maxima to 760-780 nm. This paper reports PDT of EMT-6 tumors transplanted intradermically in the thigh of BALB/c mice after topically administration of Pc, Nc and ALA in various cream preparations.

    2012-06-01

    Full Text Available Semisolid preparations for external application to skin have gained much demand, since it is easily absorbed through the skin layers. Many novel topical dosage forms have been discovered, among which organogels appears to play an important role. Organogels are thermodynamically stable, biocompatible, isotropic gel, which not only give localised effect, but also systemic effect through percutaneous absorption. Although different types of gelator molecules are being used for the development of organogels, both egg and soya lecithin are mainly focused. The purity of lecithin is also considered to be an important factor in gelation. Apart from lecithin, non-ionic surfactant based microemulsion gels and pluronic organogels are also being developed. Compared to conventional topical dosage forms, these novel formulations are found to be more advantageous and efficient. In future, organogels can give way to many promising discoveries in the field of topical dosage forms. The current review aims at giving an idea about organogels, its applications and importance in topical delivery.

    Pon, R K; Cardenas, A F; Buttler, D J; Critchlow, T J

    2007-02-15

    We introduce multiple topic tracking (MTT) for iScore to better recommend news articles for users with multiple interests and to address changes in user interests over time. As an extension of the basic Rocchio algorithm, traditional topic detection and tracking, and single-pass clustering, MTT maintains multiple interest profiles to identify interesting articles for a specific user given user-feedback. Focusing on only interesting topics enables iScore to discard useless profiles to address changes in user interests and to achieve a balance between resource consumption and classification accuracy. Also by relating a topic's interestingness to an article's interestingness, iScore is able to achieve higher quality results than traditional methods such as the Rocchio algorithm. We identify several operating parameters that work well for MTT. Using the same parameters, we show that MTT alone yields high quality results for recommending interesting articles from several corpora. The inclusion of MTT improves iScore's performance by 9% to 14% in recommending news articles from the Yahoo! News RSS feeds and the TREC11 adaptive filter article collection. And through a small user study, we show that iScore can still perform well when only provided with little user feedback.

    ABSTRACT Topical administration of non-steroidal anti-inflammatory drugs (NSAIDs) is generally considered safer than oral administration, although the former can occasionally induce cutaneous irritation. We hypothesized that the cutaneous irritation by topical NSAIDs might be suppressed by trehalose, which has protective effects on biological membranes. Using the three-dimensional cultured human skin model, Living Skin Equivalent-high, we found that cutaneous damage due to NSAIDs was reduced ...

    Owing to its ability to regenerate epidermal cells Dexpanthenol (D-panthenol; chemically known as (+)-2,4-dihydroxy-N-(3-hydroxypropyl)-3,3-dimethylbutyramide) has found use for the treatment of patholytic ileus and postoperative distention. The purpose of research was to develop a gel containing dexpanthenol by monitoring the effect of various concentrations of a gelating agent on the activity of the ciliary apparatus. A system containing 2.5% of hydroxyethylcellulose was optimal for the preparation of the gel. Together with a formulation containing 5% of dexpanthenol, drops with equal concentration of the active compound were tested for comparison. Physical characteristics, such as osmotic pressure, acidity, density and viscosity of the preparation were determined as well as its microbiological sterility. The anti-inflammatory activity of the gel was determined following its topical application. Epidermal tests showed its good tolerance after topical application to the shaved skin of guinea pigs.

  3. Workshop on beam cooling and related topics

    International Nuclear Information System (INIS)

    The sessions of the Workshop on Beam Cooling and Related Topics, held in Montreux from 4-8 October 1993, are reported in these Proceedings. This meeting brought together international experts in the field of accelerator beam cooling. Its purpose was to discuss the status of the different cooling techniques currently in use (stochastic, electron, ionization, heavy-ion, and laser) and their actual performances, technological implications, and future prospects. Certain theoretical principles (muon cooling, cyclotron maser cooling) were discussed and are reported on in these Proceedings. Also of interest in this Workshop was the possibility of beam crystallization in accelerators using ultimate cooling. In the first part of these Proceedings, overview talks on the various cooling techniques, their implications, present performance, and future prospects are presented. More detailed reports on all the topics are then given in the form of oral presentations or poster sessions. Finally, the chairmen and/or convenors then present summary talks. (orig.)

    2013-04-01

    Topical tacrolimus and pimecrolimus are indicated for the treatment of atopic dermatitis, but they have been studied in many off-label uses. We reviewed the English language literature to define their roles in treatment of vitiligo. Double-blind studies show that tacrolimus 0.1% ointment combined with excimer laser is superior to placebo, especially for UV resistant areas, such as bony prominences of the extremities. When used alone, tacrolimus 0.1% ointment is almost as effective as clobetasol propionate 0.05% ointment. Other studies suggest it can also be effective for facial lesions. Double blind studies show that pimecrolimus 1% cream combined with narrow band UVB is superior to placebo, especially for facial lesions. Additional studies would further clarify the role of topical calcineurin inhibitors in vitiligo. PMID:23331250

    2007-01-01

    The procedure of hypertext induced topic search based on a semantic relation model is analyzed, and the reason for the topic drift of HITS algorithm was found to prove that Web pages are projected to a wrong latent semantic basis. A new concept-generalized similarity is introduced and, based on this, a new topic distillation algorithm GSTDA(generalized similarity based topic distillation algorithm) was presented to improve the quality of topic distillation. GSTDA was applied not only to avoid the topic drift, but also to explore relative topics to user query. The experimental results on 10 queries show that GSTDA reduces topic drift rate by 10% to 58% compared to that of HITS(hypertext induced topic search) algorithm, and discovers several relative topics to queries that have multiple meanings.

    Patients with nonerosive reflux disease exhibit impaired esophageal mucosal integrity, which may underlie enhanced reflux perception. In vitro topical application of an alginate solution can protect mucosal biopsies against acid-induced changes in transepithelial electrical resistance (TER). We aimed to confirm this finding in a second model using 3D cell cultures and to assess prolonged protection in a biopsy model. We assessed the protective effect of a topically applied alginate solution 1 h after application. 3D cell cultures were grown by using an air-liquid interface and were studied in Ussing chambers. The apical surface was "protected" with 200 μl of either alginate or viscous control or was unprotected. The tissue was exposed to pH 3 + bile acid solution for 30 min and TER change was calculated. Distal esophageal mucosal biopsies were taken from 12 patients and studied in Ussing chambers. The biopsies were coated with either alginate or viscous control solution. The biopsies were then bathed in pH 7.4 solution for 1 h. The luminal chamber solution was replaced with pH 2 solution for 30 min. Percentage changes in TER were recorded. In five biopsies fluorescein-labeled alginate solution was used to allow immunohistological localization of the alginate after 1 h. In the cell culture model, alginate solution protected tissue against acid-induced change in TER. In biopsies, 60 min after protection with alginate solution, the acidic exposure caused a -8.3 ± 2.2% change in TER compared with -25.1 ± 4.5% change after protection with the viscous control (P < 0.05). Labeled alginate could be seen coating the luminal surface in all cases. In vitro, alginate solutions can adhere to the esophageal mucosa for up to 1 h and exert a topical protectant effect. Durable topical protectants can be further explored as first-line/add-on therapies for gastroesophageal reflux disease. PMID:25907692

    Full Text Available Porokeratosis Mibelli is a disorder of keratinization, characterized by an annular plaque with hyperkeratotic borders and an atrophic center. Since skin tumors may develop over the lesion, porokeratosis should be treated, however, there is still no standard therapy for porokeratosis. Herein we present a case of Porokeratosis Mibelli, treated with topical imiquimod, and document the healing with clinical and dermoscopic findings. The patient was a 63-year-old man without history of immunosuppression, who presented with a 3x6 cm lesion on the dorsum of the hand. Clinicopathological features revealed Porokeratosis Mibelli. After one month of treatment with imiquimod 5% cream, three times per week without occlusion, a superfical ulcer developed. At the third month of application, there was complete resolution. Pretreatment dermoscopy showed a whitish border, scaly surface, and punctate or hairpin-like blood vessels. After treatment, there were white, reticular lines and a few vessels, compatible with scar tissue. Topical imiquimod treatment was previously reported in 9 patients with Porokeratosis Mibelli. Imiquimod had been used for 6-26 weeks, with or without occlusion, leading to complete resolution of all lesions. In our case, nonocclusive treatment was successful, although the lesion was located on thick skin. In conclusion, we consider that topical imiquimod is an effective and safe treatment.

    Full Text Available Knowledge management (KM has received much attention from both academics and practitioners in the past few years. Following the KM trend, many organizations have built their own knowledge repositories or data warehouses. However, information or knowledge is still scattered everywhere without being properly managed. The rapid growth of the Internet accelerates the creation of unstructured and unclassified information and causes the explosion of information overload. The effort of browsing information through general-purpose search engines turns out to be tedious and painstaking. Hence, an effective technology to solve this information retrieval problem is much needed. The purpose of this research is to explore the application of text mining technique in organizing knowledge stored in unstructured natural language text documents. Major components of text mining techniques required for topic map in particular will be presented in detail.Two sets of unstructured documents are utilized to demonstrate the usage of SOM for topic categorization. The first set of documents is a collection of speeches given by Y.C. Wang, Chairman of the Taiwan Plastics Group, and the other is the collection of all laws and regulations related to securities and future markets in Taiwan. We also try to apply text mining to these two sets of documents to generate their respective topic maps, thus revealing the differences between organizing explicit and tacit knowledge as well as the difficulties associated with tacit knowledge.[Article content in Chinese

  1. Tracking Multiple Topics for Finding Interesting Articles

    2008-01-03

    We introduce multiple topic tracking (MTT) for iScore to better recommend news articles for users with multiple interests and to address changes in user interests over time. As an extension of the basic Rocchio algorithm, traditional topic detection and tracking, and single-pass clustering, MTT maintains multiple interest profiles to identify interesting articles for a specific user given user-feedback. Focusing on only interesting topics enables iScore to discard useless profiles to address changes in user interests and to achieve a balance between resource consumption and classification accuracy. iScore is able to achieve higher quality results than traditional methods such as the Rocchio algorithm. We identify several operating parameters that work well for MTT. Using the same parameters, we show that MTT alone yields high quality results for recommending interesting articles from several corpora. The inclusion of MTT improves iScore's performance by 25% in recommending news articles from the Yahoo! News RSS feeds and the TREC11 adaptive filter article collection.

    Full Text Available Background: Although acute radiation dermatitis (ARD is a common side-effect of radiotherapy (RT, currently there is no general consensus about its prevention or treatment of choice. Aims: The purpose of this study was to investigate whether prophylactic use of topical betamethasone 0.1% can prevent ARD caused by chest wall irradiation. Methods: Fifty-one patients who underwent modified radical mastectomy for breast cancer and were going to receive RT, were randomly assigned to receive topical betamethasone 0.1%, petrolatum or none during RT. The frequency and severity of ARD (measured using Radiation Therapy Oncology Group acute radiation morbidity scoring criteria were recorded at the end of each week during RT and two weeks after its completion. Clinical outcomes were analyzed by relevant statistical methods. Results: All patients developed some degree of ARD, the frequency and severity of which increased with time and reached the maximum at the end of the seventh week for all groups. Patients receiving betamethasone had less severe ARD than the other two groups throughout the course of the study, but this difference was significant only at the end of the third week (p =0.027. No significant difference was observed between the petrolatum and control arms. Conclusion: Prophylactic and ongoing use of topical betamethasone 0.1% during chest wall RT for breast cancer delays occurrence of ARD but does not prevent it. Petrolatum has no effect on the prevention of ARD in these patients.

  3. Topical-steroid-induced iatrogenic Cushing syndrome in the pediatric age group: A rare case report

    Full Text Available Cushing syndrome, a systemic disorder, is the result of abnormally high blood level of cortisol or other glucocorticoids. The most common cause of Cushing syndrome is prolonged exogenous administration of glucocorticoid hormones. Prolonged use of topical corticosteroids, particularly in children, may cause Cushing syndrome and suppression of the hypothalamopituitory-adrenal axis, which is less common than that of oral or parenteral route. However, iatrogenic Cushing syndrome in the infantile age group due to topical steroid is very rare and only a few patients have been reported to date in the literature. Here we report a case of iatrogenic Cushing syndrome due to topical steroid application in a 5-month-old female child admitted to the hospital for repeated episodes of fever and cough.

    Full Text Available OBJECTIVE: To compare the effectiveness of topical local anesthesia using PRILOX cream versus local anesthesia infiltration using lignocaine and adrenaline in harvesting split skin graft. METHODS: A prospective study of 58 patients requiring split skin graft was carried. One group comprising 29 patients underwent harvesting of split skin graft under topical local anesthesia using PRILOX cream while the other group had local anesthesia infiltration using lignocaine and adrenaline. RESULTS: There were no significant differences between the 2 groups in terms of operating time, per operative pain, post-operative pain and post-operative requirement of analgesia. There was significant difference in time and pain during administration of local anesthesia and patient’s acceptability/ satisfaction with method of anesthesia. CONCLUSION: Topical local anesthesia using PRILOX cream can be used effectively for harvesting of split skin graft and is good alternative to local anesthesia infiltration.

    Purpose. Evaluating the therapeutic effect of topical and intrastromal voriconazole and topical natamycin on Fusarium keratitis. Methods. 24 rabbits were selected. The stroma of their corneas was inoculated with suspension of Fusarium solani species complex. Seven days after injection they were divided into 4 groups randomly: the first group was treated with topical voriconazole (TV) 1% for one week, the second one with one-time intrastromal injection of voriconazole (ISV) 50 microgram/0.1 mL, and the third group with topical gel of natamycin (TN) for one week, and the last one did not receive any antifungal treatment. Finally the eyes were enucleated and sclerocorneal buttons were sent for histological and microbiological examinations. Results. After treatment the ISV group and TN group showed significantly lower clinical score and colony forming units than the control group (P = 0.040 and P = 0.026, resp.), but there was statistically no significant difference between control and TV groups (P = 0.249) or between ISV and TN groups (P = 0.665). In pathological evaluation, fewer chronic inflammations were reported in 2 of the 3 buttons from TV group and 3 of the 3 buttons from ISV and TN groups in comparison with the control group. Conclusion. Intrastromal injection of voriconazole seems to be effective in treatment of Fusarium keratitis as much as topical natamycin and these are more effective than topical voriconazole.

    Full Text Available Background. Lichen sclerosus (LS is an autoimmune inflammatory skin disease that leads to tissue sclerosis. Actually, the first-line treatment consists of local steroid as clobetasol propionate (CP. Polydeoxyribonucleotide (PDRN has demonstrated anti-inflammatory effects through the reduction of cytokine production and growth stimulation of fibroblast. Objective. To evaluate the efficacy of intradermal administration of PDRN in male patients suffering from genital lichen sclerosus in addition to topical 0.05% CP, as compared to administering 0.05% CP without PDRN injection. Patients/Methods. A group of male patients (n = 28; aged 25 to 65 suffering from LS were observed during topical therapy or subdermal in addition to topical therapy. Disease activity at baseline was evaluated on Investigator’s Global Assessment (IGA and the Dermatology Life Quality Index (DLQI. We used polydeoxyribonucleotide in a commercial preparation for human use and a topical CP emulsion. Results. After therapy, in all group A patients there has been a regression of most of clinical pathological signs, while there has been a moderate improvement in all group B patients. Conclusions. On site intradermal administration of PDRN, associated with CP 0.05% cream, seemed to be associated with a clinical improvement of lichen sclerosus better than CP used in single therapy.

    Full Text Available Jonisha Shepherd,1 Arash Taheri,1 Steven R Feldman1–31Center for Dermatology Research, Department of Dermatology, 2Department of Pathology, 3Department of Public Health Sciences, Wake Forest School of Medicine, Winston-Salem, NC, USABackground: Topical treatments are usually effective in mild psoriasis. However, the complexity of their use may result in low patient adherence with treatment. Combination of a vitamin D analog and a corticosteroid into a two-compound topical formulation has increased efficacy compared with either drug administered alone. Once-daily application of such a product would likely improve adherence. The purpose of this study was to determine whether twice-daily application of a calcipotriene + betamethasone topical formulation can provide improved clinical outcomes compared with once-daily treatment with the same product.Methods: A review of the literature was performed seeking clinical trials comparing once-daily versus twice-daily application of calcipotriene + betamethasone topical formulations for the treatment of psoriasis.Results: We found only one relevant clinical trial. This study showed similar efficacy and safety with once-daily versus twice-daily application of a topical calcipotriene + betamethasone formulation in the treatment of psoriasis vulgaris.Conclusion: Once-daily application of a topical calcipotriene + betamethasone formulation may offer increased patient convenience and potentially increased patient adherence with long-term treatment, compared with twice-daily use, without reducing the efficacy. In order to enhance adherence, patient preference regarding frequency of application of topical treatments should be considered when prescribing medications.Keywords: calcipotriene, betamethasone, once daily, twice daily, psoriasis, combination product

Symptoms of OAB, such as urgency, frequency, and nocturia, can be treated effectively with inhibitors of muscarinic acetylcholine receptors. Antimuscarinic agents promote relaxation of the detrusor muscle and may modulate afferent neuronal signals involved in the regulation of the micturition reflex. Despite the availability of an increasing number of oral antimuscarinic agents, treatment persistence among patients with OAB generally appears to be low. This may be attributed, at least in part, to the common occurrence of anticholinergic adverse effects, such as dry mouth, constipation, and dizziness. Oxybutynin is a well-established antimuscarinic agent that is available in a variety of formulations. Transdermal formulations have been developed to avoid the first-pass hepatic and gastrointestinal drug metabolism responsible for the anticholinergic adverse effects often observed with oral delivery of oxybutynin. Oxybutynin chloride topical gel (OTG is a formulation of oxybutynin that was approved by the US Food and Drug Administration in January 2009. OTG was the result of a systematic evidence-based effort to develop a formulation that preserves the efficacy of oral oxybutynin formulations while eliminating most of their anticholinergic adverse effects. Additional emphasis was put on creating a transdermal formulation with minimal potential for application-site skin reactions. The formulation and pharmacokinetic properties of OTG are reviewed in the context of recently published efficacy and tolerability data from a large multicenter, placebo

With a view to exploring the clinical usefulness of these findings, this study examined its preventive effect when administered topically as an eye drop.Methods: Diabetes was induced by intraperitoneal injections of streptozotocin. At the onset of diabetes, an eye drop preparation containing 2.5% sodium pyruvate was administered six times a day at 90-minute intervals. Treatment was continued for 6 weeks. Cataract formation was monitored ophthalmoscopically after mydriasis with 1% tropicamide eye drops. Subsequently, the treated and untreated diabetic animals and the age-matched normal controls were euthanized, their eyes enucleated, and the lenses isolated for biochemical assessment of protein glycation and glutathione levels.Results: Treatment with pyruvate eye drops was found to be significantly effective in inhibiting protein glycation. Glutathione levels were also better maintained. In addition, ophthalmoscopic examination revealed that the incidence of cataract in the pyruvate-treated group was only 12% as compared with the untreated diabetics in whom the incidence was 73%. Cataracts at this stage were largely equatorial.Conclusion: The results demonstrate that topical application of pyruvate can potentially be useful in attenuating or preventing cataract formation induced by diabetes and other conditions of oxidative stress.Keywords: pyruvate eye drops, diabetic cataract, protein glycation, oxidative stress

    Craighead, Daniel H; Alexander, Lacy M

    2016-09-01

    Menthol, the active ingredient in several topically applied analgesics, activates transient receptor potential melastatin 8 (TRPM8) receptors on sensory nerves and on the vasculature inducing a cooling sensation on the skin. Ilex paraguariensis is also a common ingredient in topical analgesics that has potential vasoactive properties and may alter the mechanisms of action of menthol. We sought to characterize the microvascular effects of topical menthol and ilex application and to determine the mechanism(s) through which these compounds may independently and combined alter cutaneous blood flow. We hypothesized that menthol would induce vasoconstriction and that ilex would not alter skin blood flow (SkBF). Three separate protocols were conducted to examine menthol and ilex-mediated changes in SkBF. In protocol 1, placebo, 4% menthol, 0.7% ilex, and combination menthol+ilex gels were applied separately to the skin and red cell flux was continuously measured utilizing laser speckle contrast imaging (LSCI). In protocol 2, seven concentrations of menthol gel (0.04%, 0.4%, 1%, 2%, 4%, 7%, 8%) were applied to the skin to model the dose-response curve. In protocol 3, placebo, menthol, ilex, and menthol+ilex gels were applied to skin under local thermal control (34°C) both with and without sensory nerve blockage (topical lidocaine 4%). Post-occlusive reactive hyperemia (PORH) and local heating (42°C) protocols were conducted to determine the relative contribution of endothelium derived hyperpolarizing factors (EDHFs)/sensory nerves and nitric oxide (NO), respectively. Red cell flux was normalized to mean arterial pressure expressed as cutaneous vascular conductance (CVC: flux·mmHg(-1)) in all protocols. Topical menthol application increased SkBF compared to placebo (3.41±0.33 vs 1.1±0.19CVC: peffect, p<0.05) with an ED50 of 1.0%. Similarly, SkBF was increased after menthol application during PORH (3.62±0.29 vs. 2.50±0.21flux·mmHg(-1); p<0.001), but not local heating

Variations in CER species within this layer have been linked to several skin diseases. A recent proliferation of CER-containing topical skin-care products warrants the elucidation of CER penetration profiles in both healthy and diseased skin. In the current study, the spatial distributions of CER concentration profiles, following topical application of two species of CER, were tracked using infrared imaging. Suspensions of single-chain perdeuterated sphingosine and phytosphingosine CER in oleic acid were applied, in separate experiments, to the surface of healthy intact ex vivo human skin using Franz diffusion cells. Following either a 24- or 48-hour incubation period at 34°C, infrared images were acquired from microtomed skin sections. Both CER species accumulated in glyph regions of the skin and penetrated into the SC, to a limited extent, only in these regions. The concentration profiles observed herein were independent of the CER species and incubation time utilized in the study. As a result, a very heterogeneous, sparse, spatial distribution of CERs in the SC was revealed. In contrast, oleic acid was found to be fairly homogeneously distributed throughout the SC and viable epidermis, albeit at lower concentrations in the latter. A more uniform, lateral distribution of CERs in the SC would likely be important for barrier efficacy or enhancement.Keywords: stratum corneum, infrared imaging, topical delivery, oleic acid

  1. Selected topics in heavy flavour physics

    International Nuclear Information System (INIS)

    We review the status of flavour physics in spring 2014. The numerous accurate new measurements of flavour experiments have enabled us to test our theoretical understanding of flavour processes with an unprecedented precision. At first sight the dominant amount of measurements seems to be standard model like. Having a closer look one finds, however, that in most of the observables there is still some considerable space for new effects. In addition many discrepancies are still not yet settled. For further investigations and definite conclusions an improvement of the theoretical precision as well as the experimental one is mandatory. Communicated by Professor Alan Martin (topical review)

    Full Text Available All scientific work must be carried out against a background of adequate administrative support if it is to become effective and produce useful results. Administration is not a job for which we, as scientists, are particularly trained; and it is a thing of which we tend to fight shy, partly because, author suppose, most Of peoples are associate the administrator with highly unpleasant matters such as income tax, delays in getting our pay cheques, and so on - For that reason we do not feel, always pay  sufficient attention to administrative affairs ; rather like the ostrich, we try to escape from them by merely ignoring them. But that is a wrong and unfruitful attitude to adopt. All live so much under the activities of the trained administrator that should, if, it  give a great deal of thought to our own administrative problems deliberate and conscious thought to them-and make an honest and heart-searching self analysis regarding our own possible failings.

  7. Optimizing topical antifungal therapy for superficial cutaneous fungal infections: focus on topical naftifine for cutaneous dermatophytosis.

    Science.gov (United States)

    Del Rosso, James Q; Kircik, Leon H

    2013-11-01

    Superficial cutaneous fungal infections (SCFIs) are commonly encountered in clinical practice in the United States, and comprise infections of the skin by dermatophytes and yeasts. The most common organisms causing SCFI are dermatophytes, especially Trichophyton spp. With the exception of onchomycosis and tinea capitis, most cases of SCFIs are amenable to properly selected topical antifungal therapy used over an adequate period of time. A variety of topical antifungal agents are available for the treatment of SCFIs, and they encompass a few major chemical classes: the polyenes (ie, nystatin), imidazoles (ie, ketoconazole, econazole, oxiconazole, etc), allylamines (ie, naftifine, terbinafine), benzylamines (ie, butenafine), and hydroxypyridones (ie, ciclopirox). The 2 major classes that represent the majority of available topical antifungal agents are the azoles and the allylamines. Overall, the allylamines are superior to the azoles in activity against dermatophytes, although both are clinically effective. The reverse is true against yeasts such as Candida spp and Malassezia spp, although topical allylamines have proven to be efficacious in some cases of tinea versicolor and cutaneous candidiasis. Naftifine, a topical allylamine, is fungicidal in vitro against a wide spectrum of dermatophyte fungi and has been shown to be highly effective against a variety of cutaneous dermatophyte infections. Rapid onset of clinical activity and favorable data on sustained clearance of infection have been documented with naftifine. The more recent addition of naftifine 2% cream has expanded the armamentarium, with data supporting a clinically relevant therapeutic reservoir effect after completion of therapy. PMID:24196340

  8. Topical and oral antibiotics for acne vulgaris.

    Science.gov (United States)

    Del Rosso, James Q

    2016-06-01

    Antibiotics, both oral and topical, have been an integral component of the management of acne vulgaris (AV) for approximately 6 decades. Originally thought to be effective for AV due to their ability to inhibit proliferation of Propionibacterium acnes, it is now believed that at least some antibiotics also exert anti-inflammatory effects that provide additional therapeutic benefit. To add, an increase in strains of P acnes and other exposed bacteria that are less sensitive to antibiotics used to treat AV have emerged, with resistance directly correlated geographically with the magnitude of antibiotic use. Although antibiotics still remain part of the therapeutic armamentarium for AV treatment, current recommendations support the following when used to treat AV: 1) monotherapy use should be avoided; 2) use benzoyl peroxide concomitantly to reduce emergence of resistant P acnes strains; 3) oral antibiotics should be used in combination with a topical regimen for moderate-to-severe inflammatory AV; and 4) use oral antibiotics over a limited duration to achieve control of inflammatory AV with an exit plan in place to discontinue their use as soon as possible. When selecting an oral antibiotic to treat AV, potential adverse effects are important to consider. PMID:27416309

    The Spaceport Command and Control System Project is creating a Checkout and Control System that will eventually launch the next generation of vehicles from Kennedy Space Center. KSC has a large set of Development and Operational equipment already deployed in several facilities, including the Launch Control Center, which requires support. The position of System Administrator will complete tasks across multiple platforms (Linux/Windows), many of them virtual. The Hardware Branch of the Control and Data Systems Division at the Kennedy Space Center uses system administrators for a variety of tasks. The position of system administrator comes with many responsibilities which include maintaining computer systems, repair or set up hardware, install software, create backups and recover drive images are a sample of jobs which one must complete. Other duties may include working with clients in person or over the phone and resolving their computer system needs. Training is a major part of learning how an organization functions and operates. Taking that into consideration, NASA is no exception. Training on how to better protect the NASA computer infrastructure will be a topic to learn, followed by NASA work polices. Attending meetings and discussing progress will be expected. A system administrator will have an account with root access. Root access gives a user full access to a computer system and or network. System admins can remove critical system files and recover files using a tape backup. Problem solving will be an important skill to develop in order to complete the many tasks.

  15. Hierarchical topic modeling with nested hierarchical Dirichlet process

    Institute of Scientific and Technical Information of China (English)

    Yi-qun DING; Shan-ping LI; Zhen ZHANG; Bin SHEN

    2009-01-01

    This paper deals with the statistical modeling of latent topic hierarchies in text corpora. The height of the topic tree is assumed as fixed, while the number of topics on each level as unknown a priori and to be inferred from data. Taking a nonparametric Bayesian approach to this problem, we propose a new probabilistic generative model based on the nested hierarchical Dirichlet process (nHDP) and present a Markov chain Monte Carlo sampling algorithm for the inference of the topic tree structure as welt as the word distribution of each topic and topic distribution of each document. Our theoretical analysis and experiment results show that this model can produce a more compact hierarchical topic structure and captures more free-grained topic relationships compared to the hierarchical latent Dirichlet allocation model.

    2016-07-01

    The topic tracking problem has attracted much attention in the last decades. However, existing approaches rarely consider network structures and textual topics together. In this paper, we propose a novel statistical model based on dynamic bayesian network, namely Multi-Topic Tracking Model for Dynamic Social Network (MTTD). It takes influence phenomenon, selection phenomenon, document generative process and the evolution of textual topics into account. Specifically, in our MTTD model, Gibbs Random Field is defined to model the influence of historical status of users in the network and the interdependency between them in order to consider the influence phenomenon. To address the selection phenomenon, a stochastic block model is used to model the link generation process based on the users' interests to topics. Probabilistic Latent Semantic Analysis (PLSA) is used to describe the document generative process according to the users' interests. Finally, the dependence on the historical topic status is also considered to ensure the continuity of the topic itself in topic evolution model. Expectation Maximization (EM) algorithm is utilized to estimate parameters in the proposed MTTD model. Empirical experiments on real datasets show that the MTTD model performs better than Popular Event Tracking (PET) and Dynamic Topic Model (DTM) in generalization performance, topic interpretability performance, topic content evolution and topic popularity evolution performance.

  14. Evaluating supervised topic models in the presence of OCR errors

    Walker, Daniel; Ringger, Eric; Seppi, Kevin

    2013-01-01

    Supervised topic models are promising tools for text analytics that simultaneously model topical patterns in document collections and relationships between those topics and document metadata, such as timestamps. We examine empirically the effect of OCR noise on the ability of supervised topic models to produce high quality output through a series of experiments in which we evaluate three supervised topic models and a naive baseline on synthetic OCR data having various levels of degradation and on real OCR data from two different decades. The evaluation includes experiments with and without feature selection. Our results suggest that supervised topic models are no better, or at least not much better in terms of their robustness to OCR errors, than unsupervised topic models and that feature selection has the mixed result of improving topic quality while harming metadata prediction quality. For users of topic modeling methods on OCR data, supervised topic models do not yet solve the problem of finding better topics than the original unsupervised topic models.

    Importance of document clustering is now widely acknowledged by researchers for better management, smart navigation, efficient filtering, and concise summarization of large collection of documents like World Wide Web (WWW). The next challenge lies in semantically performing clustering based on the semantic contents of the document. The problem of document clustering has two main components: (1) to represent the document in such a form that inherently captures semantics of the text. This may also help to reduce dimensionality of the document, and (2) to define a similarity measure based on the semantic representation such that it assigns higher numerical values to document pairs which have higher semantic relationship. Feature space of the documents can be very challenging for document clustering. A document may contain multiple topics, it may contain a large set of class-independent general-words, and a handful class-specific core-words. With these features in mind, traditional agglomerative clustering algori...

    The use of medicinal tar for dermatologic disorders dates back to the ancient times. Although coal tar is utilized more frequently in modern dermatology, wood tars have also been widely employed. Tar is used mainly in the treatment of chronic stable plaque psoriasis, scalp psoriasis, atopic dermatitis, and seborrheic dermatitis, either alone or in combination therapy with other medications, phototherapy, or both. Many modifications have been made to tar preparations to increase their acceptability, as some dislike its odor, messy application, and staining of clothing. One should consider a tried and true treatment with tar that has led to clearing of lesions and prolonged remission times. Occupational studies have demonstrated the carcinogenicity of tar; however, epidemiologic studies do not confirm similar outcomes when used topically. This article will review the pharmacology, formulations, efficacy, and adverse effects of crude coal tar and other tars in the treatment of selected dermatologic conditions.

  1. Three Topics in Renormalization and Improvement

    Vladikas, A

    2011-01-01

    This is an expanded version of lecture notes, delivered at the XCIII Les Houches Summer School (August 2009). Our aim is to present three very specific topics: (i) The consequences of the loss of chiral symmetry in the Wilson lattice regularization of the fermionic action and its recovery in the continuum limit. The treatment of these arguments involves lattice Ward identities. (ii) The definition and properties of mass independent renormalization schemes, which are suitable for a non-perturbative computation of various operator renormalization constants. (iii) The modification of the Wilson fermion action, by the introduction of a chirally twisted mass term (known as twisted mass QCD - tmQCD), which results to improved (re)normalization and scaling properties for physical quantities of interest.

  2. Nuclear energy - a topic of public opinion

    International Nuclear Information System (INIS)

    The establishment and extension of the communication process on the issue of nuclear energy are pointed out and the reasons for its development are analysed. Approaching the subject by writing a biography, the author followed the reporting on it in mass-media from 1974 to 1978. The contents of the reports are analysed. A long, latent phase was followed by a break-through caused by local protests at Wyhl. Then all those concerned tried to influence the opinion of the public in line with their intentions. Because of certain selective mechanisms one did not succeed in strengthening the tendency in favour of nuclear energy, on the contrary, the opposition increased to the point of open confrontation at Brokdorf and Grohnde. The late institutionalization of the topic by political parties etc. has reduced the necessity to take measures without making use of these official channels. Therefore, the time of big conflicts is said to be over. (HSCH)

    As time goes on, system administrators are presented with increasingly complicated challenges. In the early days, a team of engineers might have had to look after one or two systems. These days, one engineer can administer hundreds or thousands of systems. System administrators are gradually replacing their tools with more advanced and flexible ones. One of the choices is Python. Structurally, Python is a modern, high-level language with a very clean syntax. Python comes with many built-in libraries that can make automation tasks easier. It also has extensive set of third-party libraries and a

    Full Text Available There is an urgent need for new antibiotics and alternative strategies to combat multidrug-resistant bacterial pathogens, which are a growing clinical issue. Repurposing existing approved drugs with known pharmacology and toxicology is an alternative strategy to accelerate antimicrobial research and development. In this study, we show that celecoxib, a marketed inhibitor of cyclooxygenase-2, exhibits broad-spectrum antimicrobial activity against Gram-positive pathogens from a variety of genera, including Staphylococcus, Streptococcus, Listeria, Bacillus, and Mycobacterium, but not against Gram-negative pathogens. However, celecoxib is active against all of the Gram-negative bacteria tested, including strains of, Acinetobacter, and Pseudomonas, when their intrinsic resistance is artificially compromised by outer membrane permeabilizing agents such as colistin. The effect of celecoxib on incorporation of radioactive precursors into macromolecules in Staphylococcus aureus was examined. The primary antimicrobial mechanism of action of celecoxib was the dose-dependent inhibition of RNA, DNA, and protein synthesis. Further, we demonstrate the in vivo efficacy of celecoxib in a methicillin-resistant S. aureus (MRSA infected Caenorhabditis elegans whole animal model. Topical application of celecoxib (1 and 2% significantly reduced the mean bacterial count in a mouse model of MRSA skin infection. Further, celecoxib decreased the levels of all inflammatory cytokines tested, including tumor necrosis factor-α, interleukin-6, interleukin-1 beta, and monocyte chemo attractant protein-1 in wounds caused by MRSA infection. Celecoxib also exhibited synergy with many conventional antimicrobials when tested against four clinical isolates of S. aureus. Collectively, these results demonstrate that celecoxib alone, or in combination with traditional antimicrobials, has a potential to use as a topical drug for the treatment of bacterial skin infections.

    Full Text Available PURPOSE: Fluoroquinolones are antimicrobial agents that have a broad spectrum of activity and are widely used against many of the ocular pathogens, responsible for conjunctivitis, blepharitis, corneal ulcers etc. The aim of our study was to evaluate the ocular pharmacokinetics of sparfloxacin (0.3% w/v in the aqueous humour of rabbits. MATERIALS AND METHODS: Pharmacokinetics of topically administered sparfloxacin were determined after a single application of 50 µl topically. The aqueous humour samples were collected at 0, 0.25, 0.5, 1, 2, 3, 4, 5 or 6 hours after instillation. High Performance Thin Layer Chromatographic method was used to analyse the drug concentration in the aqueous humour samples. RESULTS: Fifteen minutes after the instillation of 50 µl of sparfloxacin 0.3% solution, the mean concentration in aqueous humour was found to be 1.4 µg/ml, which reaches the peak level of 3.7 µg/ml after 1.3 hours. At 6 hours, the sparfloxacin aqueous levels were 0.562 µg/ml. The clinical efficacy was predicted based on the Maximum Concentration (Cmax: Minimum Inhibitory Concentration (MIC and Area Under the Concentration-time curve (AUC:MIC ratios. CONCLUSION: The sparfloxacin levels in aqueous humour of rabbits are sufficiently high up to the 6 hours after instillation in the conjunctival sac to provide bactericidal effect against most of the ocular pathogens. Both Cmax:MIC and AUC:MIC ratios are high enough to provide bactericidal effect against most of the ocular pathogens. Sparfloxacin (0.3% ophthalmic preparation has excellent penetration through cornea.

According to the results obtained in this highly sensitive specie for ecotoxicological tests, this product did not provoke neither mortality, nor toxicity for the Apis mellifera bee.

  10. Unintentional topical lindane ingestions--United States, 1998-2003.

    Science.gov (United States)

    2005-06-01

    Lindane is an organochlorine pesticide found in certain prescription-only shampoos and topical lotions used to treat pediculosis (i.e., lice infestation) and scabies; lindane has been associated with human neurologic toxicity. In 2004, CDC was alerted to cases of illness caused by unintentional ingestion of lindane by persons mistaking the product for a liquid oral medication (e.g., cough syrup). To assess the extent of illness from ingestion of lindane, CDC, with assistance from the U.S. Environmental Protection Agency, Food and Drug Administration (FDA), and state health departments, collected case reports and analyzed data from the Sentinel Event Notification System for Occupational Risks-Pesticides (SENSOR-Pesticides) program and the Toxic Exposure Surveillance System (TESS). This report summarizes the results of that analysis, which identified 870 cases of unintentional lindane ingestion during 1998-2003, and describes two examples of lindane ingestions. To reduce the risk of lindane ingestion, public health authorities should alert clinicians to the hazards of lindane and the importance of following FDA usage guidelines, which include dispensing lindane in manufacturer-produced, 1- or 2-ounce single-use containers.

Tazarotene exerts anti-inflammatory and immune-modulating activities toward both infective agents and damaged keratinocytes. Given the well-documented efficacy of tazarotene on hyperkeratotic nail psoriasis, we investigated its therapeutic use in onychomycosis. Patients and methods: We designed a preliminary open clinical trial in patients affected by distal and lateral subungual onychomycosis of the toenails and verified the fungistatic activity of tazarotene in vitro. Fifteen patients were treated with topical tazarotene 0.1% gel once per day for 12 weeks. Mycological cultures and potassium hydroxide stains of nail samples were performed at the beginning and at the end of the study. Treatment was considered effective when clinical healing and negative mycological culture were obtained. Onycholysis, nail bed discoloration, and subungual hyperkeratosis were measured using standardized methodologies and analyzed by means of Mann–Whitney test and analysis of variance. Fungistatic activity of tazarotene was evaluated by disk diffusion assay. Results: Six patients (40% reached a mycological cure on target nail samples already after 4 weeks of treatment. Complete clinical healing and negative cultures were reached in all patients at week 12, with a significant improvement of all clinical parameters of the infected nails.

  20. Special Topics in Radiography. Chapter 10

    International Nuclear Information System (INIS)

    Up to this point, this handbook has described the use of X rays to form 2-D medical images of the 3-D patient. This process of reducing patient information by one dimension results in an image of superimposed tissues where important information might be obscured. Chapter 11 begins a section of the book involving the creation of cross-sectional medical images through computed tomography (CT), ultrasound and magnetic resonance imaging (MRI). This Chapter describes a number of special X ray imaging modalities and their associated techniques, and forms a transition between projection and cross-sectional imaging. The first of these special topics is dental radiography, which is characterized by a diversity of technology and innovation. The common intraoral radiograph of a single tooth has seen little fundamental change since the time of Roentgen and is, today, along with the simple chest radiograph, the most commonly performed radiographic examination. By contrast, the challenge to create an image of all the teeth simultaneously has placed dentistry at the cutting edge of technology, through the development of panographic techniques and, most recently, with the application of cone beam CT (CBCT). Moreover, the small size of the tooth and the consequent reduced need for X ray generation power promotes equipment mobility. The effect of the need for equipment mobility also forms a special topic that is examined in this chapter. Quantification of the composition of the body is another special X ray imaging technique. Dual energy X ray absorptiometry (DXA) is primarily used to derive the mass of one material in the presence of another, through knowledge of their unique X ray attenuation at different energies. DXA’s primary commercial application has been to measure body mineral density as an assessment of fracture risk and to diagnose osteoporosis; thus, the X ray energies used are optimized for bone density assessment. Currently, there are estimated to be over 50 000

The mean particle size of the nanoparticles was 95.3 nm, and the entrapment efficiency and drug loading for quercetin were 48.5% and 2.45%, respectively. Topical delivery in vitro and in vivo of the quercetin-loaded nanoparticles was evaluated using quercetin propylene glycol solution as the control.Results: Compared with quercetin solution, the quercetin-loaded nanoparticles showed higher permeation ability, and significantly increased accumulation of quercetin in the skin, especially in the epidermis. Microstructure observation of the skin surface after administration indicated that the interaction between ingredients of the nanoparticles and the skin surface markedly changed the morphology of the stratum corneum and disrupted the corneocyte layers, thus facilitating the permeation and accumulation of quercetin in skin.Conclusion: Lecithin-chitosan nanoparticles are a promising carrier for topical delivery of quercetin.Keywords: quercetin, tocopheryl polyethylene glycol succinate, lecithin, chitosan, nanoparticles, topical delivery

Although nonsteroidal anti-inflammatory drugs (NSAIDs are often prescribed for osteoarthritis pain, they pose age-related cardiovascular, renal, and gastrointestinal risks. Two topical NSAIDs, diclofenac sodium 1% gel (DSG and diclofenac sodium 1.5% in 45.5% dimethylsulfoxide solution (D-DMSO, are approved in the US for the treatment of osteoarthritis pain. Topical NSAIDs have shown efficacy and safety in knee (DSG, D-DMSO and hand (DSG osteoarthritis. Analyses of data from randomized controlled trials of DSG in hand and knee osteoarthritis demonstrate significant improvement of pain and function in both younger patients (<65 years and older patients (≥65 years and suggest good safety and tolerability. However, long-term safety data in older patients are limited. Topical NSAIDs can ease medication administration and help address barriers to pain management in older patients, such as taking multiple medications and inability to swallow, and are a valuable option for long-term care providers.

    Oral acitretin is currently indicated for the treatment of severe psoriasis in adults, but its use is limited by systemic side effects and teratogenicity. Topical administration of acitretin may lessen the risk of systemic toxicity while increasing local bioavailability in the skin. The effects of topical acitretin on reconstructed human epidermis (RHE) and Rhino mice were investigated and compared to those of currently marketed topical retinoids: tretinoin and tazarotene. In acitretin-treated RHE cultures, there was a reduction in keratohyalin granules and filaggrin expression in the stratum granulosum, a loss of keratin 10 expression in the stratum spinosum, and an increase in keratin 19 expression in all viable cell layers. All retinoids showed similar signs of activity in RHE cultures. Furthermore, the release of pro-inflammatory cytokines IL-1alpha and IL-8 in RHE cultures was less pronounced with acitretin compared to tretinoin- and tazarotene-containing formulations, suggesting that acitretin may be less irritating. In Rhino mice, acitretin induced a local, dose-dependent reduction in utricle diameter after seven daily dermal doses. A similar effect was observed in tretinoin- and tazarotene-treated mice. Our data suggest that topical application of acitretin may have a therapeutic benefit in the local management of keratinization disorders. PMID:17637822

    Full Text Available BACKGROUND AND OBJEC TIVE: Propofol is the most common induction agent for LMA insertion. Sodium thiopentone alone doesn’t suppress airway reflexes adequately. So this study was designed to assess whether application of topical lignocaine prior to sodium thiopentone administration w ould produce LMA insertion conditions as good as propofol. METHODS: one hundred patients of either sex in the age range of 16 – 60 years belonging to ASAI/II scheduled for open cholycystectomy were selected and allocated into one of the two groups. All patie nts received fentanyl intravenously 3minutes before induction. Group IP received propofol 2.5mg/kg while as Group IIT received topical lignocaine and intravenous sodium thiopentone. Insertion conditions for Proseal LMA like gagging, coughing and laryngospa sm were compared between the two groups. Duration of apnoea was also compared between two groups. RESULTS: There was no difference between two groups in gagging, coughing, laryngospasm. Number of attempts of Proseal LMA insertion and oxygen saturation were same between the two groups but the duration of apnoea was more in propofol than in topical lignocaine and sodium thiopentone group. CONCLUSION: Topical lignocaine and sodium thiopentone provided same insertion conditions for Proseal LMA as provided by pr opofol.

    Liposomes in the nanosize range have been recognized as a versatile drug delivery system of both hydrophilic and lipophilic molecules. In order to develop a liposome-based topical vaccination strategy, five different types of liposomes were tested as a putative vaccine delivery system on pig ear skin. The investigated liposomes mainly varied in size, lipid composition, and surface charge. Using hydrophilic and hydrophobic fluorescent dyes as model drugs, penetration behavior was studied by means of confocal laser scanning microscopy of intact skin and histological sections, respectively. Follicular penetration of the liposomes was measured in comparison to a standard, nonliposomal formulation at different time points. Dependent on time but independent of their different characters, the liposomes showed a significantly higher penetration depth into the hair follicles compared to the standard formulation. The standard formulation reached a relative penetration depth of 30% of the full hair follicle length after seven days, whereas amphoteric and cationic liposomes had reached ~70%. Penetration depth of negatively charged liposomes did not exceed 50% of the total follicle length. The fluorescence dyes were mainly detected in the hair follicle; only a small amount of dye was found in the upper parts of the epidermis.

The analysis revealed that the most effective antibacterial drug against microbial isolates in children (i.e., Staphylococci spp. was levofloxacin. MIC for this agent against Streptococci spp. and Gram-negative microbes was low as well. Moxifloxacin is preferred for the treatment of ocular inflammation provoked by Streptococci spp. as MIC of this antimicrobial against Streptococci spp. was the lowest. MIC of ciprofloxacin against Gram-negative flora was the lowest. These data demonstrate generally recognized high efficacy of this drug. MIC value for tobramycin against all bacterial isolates was the highest.

  8. Mining Social Entrepreneurship Strategies Using Topic Modeling

    Science.gov (United States)

    2016-01-01

    Despite the burgeoning research on social entrepreneurship (SE), SE strategies remain poorly understood. Drawing on extant research on the social activism and social change, empowerment and SE models, we explore, classify and validate the strategies used by 2,334 social entrepreneurs affiliated with the world’s largest SE support organization, Ashoka. The results of the topic modeling of the social entrepreneurs’ strategy profiles reveal that they employed a total of 39 change-making strategies that vary across resources (material versus symbolic strategies), specificity (general versus specific strategies), and mode of participation (mass versus elite participation strategies); they also vary across fields of practice and time. Finally, we identify six meta-SE strategies―a reduction from the 39 strategies―and identify four new meta-SE strategies (i.e., system reform, physical capital development, evidence-based practices, and prototyping) that have been overlooked in prior SE research. Our findings extend and deepen the research into SE strategies and offer a comprehensive model of SE strategies that advances theory, practice and policy making. PMID:26998970

    2001-07-01

    This review paper illustrates the different SQUID based systems used for biomagnetic imaging. The review is divided into nine sections. The first three sections are introductory: section 1 is a short overview of the topic; section 2 summarizes how the biomagnetic fields are generated and what are the basic mathematical models for the field sources; section 3 illustrates the principles of operation of the SQUID device. Sections 4-8 are specifically devoted to the description of the different systems used for biomagnetic measurements: section 4 discusses the different types of detection coils; section 5 illustrates the SQUID sensors specifically designed for biomagnetic applications together with the necessary driving electronics, with special emphasis on high-temperature superconductivity (HTS) SQUIDs, since HTS devices are still in a developing stage; section 6 illustrates the different noise reduction techniques; section 7 describes the different multichannel sensors presently operating; and, finally, section 8 gives a hint of what kind of physiological and/or clinical information may be gathered by the biomagnetic technique. Section 9 suggests some future trends for the biomagnetic technique.

    With the aim of improving the antioxidant activity of polyphenols from blueberries (Vaccinium myrtillus) on skin targets after topical application, ethanolic extracts from three blueberry varieties (named Millenia, O'Neal, and Blue Crisp) were loaded into ultradeformable liposomes. These nanocarriers are known to be capable of penetrating through the stratum corneum reaching its deeper layers and the viable epidermis. On the other hand, blueberries contain large amounts of polyphenols, whose antioxidant properties as tissue protectors against processes mediated by reactive oxygen species have been extensively proved. Blueberries are usually consumed as edible products, but their antioxidant compounds are poorly absorbed. The antioxidant properties of the extracts were screened before and after being loaded into ultradeformable liposomes made of soy phosphatidylcholine and sodium cholate, of nearly 100 nm in size at 0.223 extract/lipid w/w. The ethanolic extract-loaded ultradeformable liposomes (nanoberries) from Millenia variety retained an 85% of the antioxidant capacity of the free extract and showed low cytotoxicity on HaCaT cells (less than 20%) at active concentration against free radicals.

    2011-01-01

    We report recent studies on structure functions of the nucleon and nuclei. First, clustering effects are investigated in the structure function F_2 of Be-9 for explaining an unusual nuclear correction found in a JLab experiment. We propose that high densities created by formation of clustering structure like 2*alpha+neutron in Be-9 is the origin of the unexpected JLab result by using the antisymmetrized molecular dynamics (AMD). There is an approved proposal at JLab to investigate the structure functions of light nuclei including the cluster structure, so that much details will become clear in a few years. Second, tensor-polarized quark and antiquark distributions are obtained by analyzing HERMES measurements on the structure function b_1 for the deuteron. The result suggests a finite tensor polarization for antiquark distributions, which is an interesting topic for further theoretical and experimental investigations. An experimental proposal exists at JLab for measuring b_1 of the deuteron as a new tensor-st...

  14. Topics in the structure of hadronic systems

    International Nuclear Information System (INIS)

    In this dissertation the author examines a variety of different problems in the physics of strongly-bound systems. Each is elucidated by a different standard method of analysis developed to probe the properties of such systems. He begins with an examination of the properties and consequences of the current algebra of weak currents in the limit of heavy quark spin-flavor symmetry. In particular, he examines the assumptions in the proof of the Ademollo-Gatto theorem in general and for spin-flavor symmetry, and exhibit the constraints imposed upon matrix elements by this theorem. Then he utilizes the renormalization-group method to create composite fermions in a three-generation electroweak model. Such a model is found to reproduce the same low energy behavior as the top-condensate electroweak model, although in general it may have strong constraints upon its Higgs sector. Next he uncovers subtleties in the nonrelativistic quark model that drastically alter the picture of the physical origins of meson electromagnetic and hyperfine mass splittings; in particular, the explicit contributions due to (md-mu) and electrostatic potentials may be overwhelmed by other effects. Such novel effects are used to explain the anomalous pattern of mass splittings recently measured in bottom mesons. Finally, he considers the topic of baryon masses in heavy fermion chiral perturbation theory, including both tree-level and loop effects

  15. Topics in calorimetry for high energy physics

    International Nuclear Information System (INIS)

    These lectures focus on a series of topics now of interest or which have been of interest to designes of calorimeters in the past few years. The examples concentrate on calorimeters from DESY because its focus this year is on e-P physics, and on CDF and SDC because they are best known to the author. Calorimeters are, broadly speaking, devices to measure the total energy of particles. In general, no one device will be optimal for all types of particles. The two broadest classes of calorimeters in high energy physics are the electromagnetic calorimeters used primarily for photons and electrons, and the hadronic calorimeters used for most charged mesons and baryons. Most operate by absorbing and thereby measuring a significant amount of the incoming particles energy directly. Some particles may require special devices for their interactions and observation. Modern calorimeters are characterized by energy and position resolution, and cost and size. Calorimeter cost is often a trade-off between performance desired and money available. The optimum cost will require a careful choice of materials, reduction of the overall size of the detector, elimination of labor intensive construction techniques, and careful consideration of the cost of calibration systems. Since at least some of these requirements which optimize cost and resolution are contradictory, the ideal calorimeter in seldom what one ends up building

  16. Application of lidar to current atmospheric topics

    Sedlacek, A.J. III [ed.] [Brookhaven National Lab., Upton, NY (United States). Dept. of Advanced Technology

    1996-12-31

    The goal of the conference was to address the various applications of lidar to topics of interest in the atmospheric community. Specifically, with the development of frequency-agile, all solid state laser systems, high-quantum-efficiency detectors, increased computational power along with new and more powerful algorithms, and novel detection schemes, the application of lidar to both old and new problems has expanded. This expansion is evidenced by the contributions to the proceedings, which demonstrate the progress made on a variety of atmospheric remote sensing problems, both theoretically and experimentally. The first session focused on aerosol, ozone, and temperature profile measurements from ground-based units. The second session, Chemical Detection, provided applications of lidar to the detection of atmospheric pollutants. Papers in the third session, Wind and Turbulence Measurements, described the Multi-center Airborne Coherent Atmospheric Wind Sensor (MACAWS) experiments, Doppler techniques for ground-based wind profiling and mesopause radial wind and temperature measurements utilizing a frequency-agile lidar system. The papers in the last two sessions, Recent Advanced in Lidar Technology and Techniques and Advanced Operational Lidars, provided insights into novel approaches, materials, and techniques that would be of value to the lidar community. Papers have been processed separately for inclusion on the data base.

    A topical preparation containing aceclofenac was developed using an o/w microemulsion system. Isopropyl myristate was chosen as the oil phase as it showed a good solubilising capacity. Pseudo-ternary phase diagrams were used to obtain the concentration ranges of the oil, surfactant (Labrasol) and co-surfactant (plurol oleique) for microemulsion formation. Five different formulations were formulated with various amount of the oil (5-25%), water (10-50%), and the mixture of surfactant and co-surfactant at the ratio of 4 (45-65%). In vitro permeability of aceclofenac from the microemulsions was evaluated using Keshary Chien diffusion cells with 0.45-μm cellulose acetate membrane. The amount of the aceclofenac permeated was analyzed by HPLC and the droplet size and zeta potential of the microemulsions was determined using a Zetasizer Nano-ZS. The mean diameters of the microemulsion droplets approximately ranged between 154 - 434 nm, and the permeability of aceclofenac incorporated into the microemulsion systems was 3 folds higher than that of the marketed formulation. These results indicate that the microemulsion system studied is a promising tool for percutaneous delivery of aceclofenac. PMID:24363700

    @@ The long-anticipated anti-monopoly law needs to better address the crucial distinction between administrative and economic monopolies The first five months of 2oo6 saw a surge in the profits achieved by key State enterprises, especially in the eight sectors including petroleum, telecommunication and electricity, which achieved 285 billion yuan (US$36 billion) in profits, accounting for about 86 percent of the total, according to a July report. From the Stateowned Assets Supervision and Administration Commission of the State (SASAC). This news was both heartening and disquieting, for the most profitable sectors happen to be monopolistic enterprises, mostly upstream the production chain, who achieve their profitability at the expense of those companies further downstream. For years these sectors have been at the centre of the "bust-the-trust" storm.

    Little is known about the metabolising capacity of the human skin in relation to topically applied drugs and formulations. We chose lidocaine as a model compound since the metabolic pathways are well known from studies concerning hepatic metabolism following systemic drug administration. However......, the enzymes involved are also expressed in the skin. Hence, the aim of the current study was to investigate the extent of the cutaneous in vivo metabolism of topically applied lidocaine in human volunteers. A dose of 5 mg/cm(2) of Xylocaine(R) (5% lidocaine) ointment was applied onto the buttock skin...... of the volunteers. After 2 h, residual formulation was removed, and two 4-mm punch biopsies were taken from each volunteer. The quantity of lidocaine extracted from the skin samples (epidermis + dermis) was 109 +/- 43 ng/mm(2) skin. One metabolite (monoethylglycine xylidide, MEGX) was detected in...

    Twenty-four consecutive patients scheduled for fiberbronchoscopy were randomized to receive double-blind either intravenous (1.5 mg/kg) or laryngotracheal (3 mg/kg) lidocaine to evaluate the influence on post-bronchoscopic laryngospasm, pain in the throat and coughing. Plasma lidocaine concentrations were analyzed 5, 15, 30 and 60 min after administration. None of the patients demonstrated laryngospasm or pain in the throat during the first hour after bronchoscopy. Patients receiving topical lidocaine coughed significantly more than patients receiving intravenous lidocaine, with a median number of coughs of 20 compared to 4, during the first hour (P less than 0.01). The plasma lidocaine concentrations were significantly higher after intravenous than after topical administration (P less than 0.001). After intravenous administration the plasma lidocaine concentrations exceeded the accepted level for potential toxicity in five out of 11 patients, but none of the patients developed toxic symptoms and no side-effects were observed.

  13. Inertial confinement fusion and related topics

    International Nuclear Information System (INIS)

    The current state of different approaches (laser fusion, light and heavy ions, electron beam) to the realization of inertial confinement fusion is considered. From comparative analysis a conclusion is made that from the viewpoint of physics, technology, safety, and economics the most realistic way to future energetics is an electric power plant based on a hybrid fission-fusion reactor which consists of an external source of neutrons (based on laser fusion) and a subcritical two-cascade nuclear blanket, which yields the energy under the action of 14 MeV neutrons. The main topics on inertial confinement fusion such as the energy driver, the interaction between plasmas and driver beam, the target design are discussed. New concept of creation of a laser driver for IFE based on generation and amplification of radiation with controllable coherence is reported. The performed studies demonstrate that the laser based on generation and amplification of radiation with controllable coherence (CCR laser) has a number of advantages as compared to conventional schemes of lasers. The carried out experiments have shown a possibility of suppression of small-scale self-focusing, formation of laser radiation pulses with required characteristics, simplification of an optical scheme of the laser, good matching of laser-target system and achievement of homogeneous irradiation and high output laser energy density without using traditional correcting systems (phase plates, adaptive optics, space filters etc.). The results of the latest experiments to reach ultimate energy characteristics of the developed laser system are also reported. Recent results from the experiments aimed at studying of the physical processes in targets under illumination by the laser with controllable coherence of radiation are presented and discussed, especially such important laser-matter interaction phenomena as absorption and scattering of the laser radiation, the laser radiation harmonic generation, X

    El-Heis, S; Buckley, D A

    2015-05-01

    Topical calcineurin inhibitors have been used outside their approved indications for a number of conditions, including topical steroid-induced rosacea. However, tacrolimus ointment itself has been reported to trigger rosacea in a small number of cases. We report a case of a rosacea-like eruption in a 39-year-old woman occurring after the use of pimecrolimus cream for 12 months for atopic dermatitis. Withdrawal of pimecrolimus combined with treatment with oral lymecycline, topical metronidazole, and an emollient resulted in resolution of the eruption. There have been 5 previously reported cases of a topical pimecrolimus-induced rosacea-like eruption suggesting that this rare side-effect may be a class effect of all topical calcineurin inhibitors. Dermatologists prescribing these drugs should be aware of this uncommon complication and may wish to warn patients of its occurrence as a potential side-effect when using topical calcineurin inhibitors in facial skin in adults.

    2013-02-01

    Seborrheic dermatitis is a multifactorial skin disease characterized by a chronic course with periods of exacerbation and remission. Although topical corticosteroids have been the mainstay of treatment, alternative therapies are often needed to avoid protracted use of topical corticosteroid therapy in order to avert side effects and to sustain control of the disorder. Topical pimecrolimus, a calcinuerin inhibitor, is a safe alternative for seborrheic dermatitis and is more ideal for long-term use. More specifically, topical pimecrolimus not only has an attractive safety profile with no risk of many of the potential side effects seen with topical corticosteroids, but also has favorable efficacy data, including more data on long-term use. This is a review of literature evaluating the efficacy and safety profile of topical pimecrolimus 1% cream for the treatment of seborrheic dermatitis. PMID:23441238
