    AIM: To investigate the relationship between cytokine level and nitric oxide (NO) content in aqueous humor after intraocular lens implantation. METHODS: All New Zealand rabbits were divided randomly into three groups: (1) control group, (2) extracapsular cataract extraction group (ECCE), (3) extracapsular cataract extraction and posterior chamber intraocular lens implantation group (ECCE+IOL). The inflammation of all experimental rabbit eyes, including cornea edema and anterior chamber exudation were observed via zoom-photo slitlamp microscope 1,3,7,14,30 d postoperation. Meanwhile, aqueous humor was drawn for white blood cell (WBC) counting and classifying, and for NO-2/NO-3 and cytokine assay, including interleukin-2(IL-2), tumour necrosis factor-α(TNF-α). Statistics were taken by SPSS softwear. RESULTS: (1) Total WBC in aqueous humor were higher and anterior chamber exudation were more severe in ECCE+IOL group than that in ECCE group and control group. (2) The level of IL-2 and TNF-α and the content of NO-2/NO-3 in aqueous humor of ECCE+IOL group were higher than that in ECCE group and control group 1-14 d postoperation respectively, and it increased to peak value at 3-7 d postoperation and decreased gradually after two weeks postoperation. (3) The change regularity of IL-2, TNF-α and NO-2/NO-3 in each group were basically similar, i.e. when the level of cytokine (IL-2 and TNF-α) was normal, the content of NO-2/NO-3 was normal too, when the level of cytokine (IL-2 and TNF-α) increased, the content of NO-2/NO-3 increased too. CONCLUSION: The intraocular inflammation after ECCE+IOL was more severe than that after simple ECCE. NO, IL-2 and TNF-α play an important role in intraocular inflammation after intraocular lens implantation. The changes of IL-2 and TNF-α level was closely related with NO content in aqueous humor.

    AIM To report the association between melatonin levels in aqueous humor and serum, and diabetic retinopathy (DR) grade in type 2 diabetic patients. METHODS Aqueous humor and plasma samples from 26 patients with DR (in nonproliferative and proliferative stages) and 14 control subjects were collected during cataract surgery after 6 p.m. Melatonin concentrations were determined using an enzyme-linked immunosorbent assay (ELISA). RESULTS Melatonin levels were significantly higher in the aqueous humor of patients with proliferative diabetic retinopathy (PDR) [18.57±2.67 pg/mL (range 15.20-23.06) vs 13.63±2.71 pg/mL (range 10.20-20.20), P=0.0001], but not in those with nonproliferative retinopathy (NPDR) [13.79±2.56 pg/mL (range 9.80-20.10) vs 13.63±2.71 pg/mL (range 10.20-20.20), P=0.961] compared to controls. There was decrement in the plasma melatonin level of patients with PDR, but no significant differences between the plasma melatonin levels of the study groups [5.37±1.74 pg/mL (range 2.85-8.65) vs 6.11±1.90 pg/mL (range 3.13-9.41), P=0.293], or between control and DR groups [NPDR 6.11±1.90 pg/mL (range 3.13-9.41) vs control 6.15±1.91 pg/mL (range 2.18-9.86); PDR (5.37±1.74 pg/mL (range 2.85-8.65) vs control 6.15±1.91 pg/mL (range 2.18-9.86), P=0.808, P=0.264]. CONCLUSION Elevated melatonin levels in aqueous humor in PDR may indicate the level to be associated with DR severity. PMID:27275429

    Purpose. To study the interleukin 1 (IL-1) levels in aqueous humor after transscleroal fixation of intraocular lenses (IOLs) implantation in rabbits and disciss the effect of IL-1 on postoperative anterior ocular inflammation, Methods. Twenty-seven pigmented rabbits were divided into three groups: G1, transscleral fixation of posterior chamber (PC) IOLs implantation; G2, Lens of rabbits were removed without IOLs implantation; GS, the control group, without surgical intervention. On the Ist, 3rd, 7th and 14th postoperative days, aqueous humor samples were obtained. Methyl thiazolyl tetrazolium(MTT) colormetry was used to detected for the presence of IL-1. The data were analyzed hy using analysis of variance of SAS soft ware. Results. It was found that IL-1 level in aqueous humor was increased after transscleral fixation of IOLs implantatlon, IL-1 level reached its maximum on the 14th postoperative days in the IOL implanted group. IL-1 levels on 1st, 3rd, 7th and 14th days postoperatively was significantly higher (P<0. 05) in IOLs implanted group than that of only extracapsular lenses extraction but no IOLs implantation group and that of the none sttrgical intervention group. Conclusions. IL-1 levels increased had a close relationship with a specific response to IOL implantation. The increase of IL-1 may be suggested as the principal mediators of immunological and inflammlatory responses, so that may play critical role in anterior ocular inflammative response after IOL implantation.

    Full Text Available Abstract Background The transmembrane glycoprotein CD44 is a major hyaluronan cell surface receptor widely distributed in eye tissues and fluids. The shed ectodomain of CD44 is termed soluble CD44 and is toxic to human retinal ganglion cells in cell culture. The purpose of this study was to investigate the concentration of sCD44 in the aqueous humor (AH of normal subjects, patients with primary open-angle glaucoma, and patients with degenerative myopia but without glaucoma, to determine if the molecule might serve as a protein marker of glaucoma. Findings In this case-control study, AH samples were collected from controls (n = 16, patients with primary open-angle glaucoma (n = 11, and patients with degenerative myopia (n = 11 who underwent phacoemulsification surgery to treat mature or immature cataracts. The sCD44 concentration in AH was measured using a commercial ELISA kit. In normal AH samples the sCD44 concentration was 5.40 ± 1.21 ng/mL, whereas in degenerative myopia patients the sCD44 concentration was 5.76 ± 1.15 ng/mL. There was thus no statistically significant difference between these two groups (p > 0.05. The aqueous sCD44 concentration in patients with primary open-angle glaucoma (12.2 ± 10.1 ng/mL was higher than that of the control group (p Conclusion sCD44 may be a protein marker of primary open-angle glaucoma.

    Purpose To investigate the chemokine expression profiles in the aqueous humor of wet age-related macular degeneration (wet AMD) patients and to correlate their levels with clinical findings. Methods Undiluted aqueous humor samples (100–200 μl) were obtained from 16 wet AMD eyes and 12 control eyes. Forty chemokines were measured using a multiplex method. A 6×6 mm area of the macular region centered on the fovea was examined using spectral domain optical coherence tomography (SD-OCT). Results The detection rates were 50% or more for 15 chemokines. Compared with the control group, the aqueous humor in wet AMD patients showed a significantly higher expression of CXCL10 (p=0.004), CCL14 (p=0.002), CXCL16 (p=0.013), CXCL7 (p=0.033), and CCL22 (p=0.037), while growth-related oncogene (GRO) was significantly decreased in the wet AMD patients (p=0.001). When compared with treatment-naïve patients, the recurrent group had significant upregulation of CXCL10 (p=0.012) and CCL22 (p=0.002). CXCL16 was positively correlated with lesion size, and CCL22 was higher in patients whose OCT images showed intraretinal fluid (IRF) or hyperreflective foci (HF). Conclusions Elevated levels of inflammation-related chemokines, including CXCL10, CCL14, CXCL16, CXCL7, and CCL22, in the aqueous humor of AMD patients may suggest a pathogenic role for inflammation. CXCL10 and CCL22 were more elevated in eyes with recurrent wet AMD than in treatment-naïve eyes. CXCL16 was positively correlated with lesion size. The increase in CCL22 was correlated with the presence of IRF or HF. These data may be of interest in the search for biomarkers associated with wet AMD and may potentially indicate different treatment strategies. PMID:27122966

    Laser Raman scattering has been used to monitor glucose and lactate metabolites within aqueous humor specimens obtained from nine human eyes during cataract surgery. Nine postmortem rabbit eyes were also investigated. Raman measurements were obtained using a single grating Raman spectrometer with a liquid nitrogen cooled CCD. A 514.5 nm line from an argon laser was used to illuminate capillaries containing several microliters of aqueous humor. A water background was subtracted from each of the aqueous humor Raman spectra. This experimental system was calibrated so that each metabolite in water could be measured down to 0.1 weight percent. Raman peaks indicative of the stretching vibrations of methylene and methyl groups associated with glucose and lactate, respectively, were observed in the human specimens. A second stretching mode characteristic of lactate between the carbon atom and either the carboxylic acid group or carboxylate ion group was also observed providing a distinguishing feature between the glucose and lactate Raman peaks. Similar structure was observed from the rabbit specimens, but these samples have recently been found to have been contaminated during euthanasia.

    In 13 rabbits, 1 month to 1 year after posterior chamber lens implantation/polymethylmetacrylate/, the level of aqueous humor proteins was evaluated and the proteins separation in polyacylamide gel was performed. The studies were also carried out in unoperated eyes of the same animals and control group was composed of the eyes before surgery. It was found that in pseudophakic eyes an increased level of proteins remained during the whole year/the highest one month after surgery, slowly decreasing afterwards/, with the appearance of additional fractions. The moderate increase of the proteins concentration was also observed in unoperated eyes. The increase of aqueous humor proteins in pseudophakic eyes indicates that the presence of polymethyl metacrylate is not completely indifferent to the eyeball in spite of the suggestions derived from the clinical observations.

    Full Text Available In 2010, there were estimated to be approximately 60.5 million people with glaucoma. This number is expected to increase to 79.6 million by 2020. In 2010, there were 8.4 million people with bilateral blindness caused by glaucoma, and this number is expected in increase to 11.2 million by 2020. Filtering implants are special devices that have been developed to reduce intraocular pressure in patients with refractory glaucoma. The success rate of these implants is relatively low, and they continue to fail over time. To avoid failure caused by the formation of scar tissue around the implants, attempts have been made to drain the aqueous humor to various sites, including the venous system, lacrimal sac, sinuses, and conjunctival fornix. Recently, a system to shunt aqueous humor from the anterior chamber to the peritoneum has been developed. The surgical technique involved in this system is a modification of the technique currently used by neurosurgeons for the treatment of hydrocephalus. We present the first case operated using this technique.

    Full Text Available Purpose: To measure oxygen tension in the aqueous humor of human eyes under different oxygenation conditions. Methods: This prospective comparative interventional case series consisted of two parts. In the first part, 120 consecutive patients scheduled for cataract surgery were randomized into group I (control group in which surgery was performed under local anesthesia inhaling 21% oxygen; group II in whom general anesthesia using 50% oxygen was employed; and group III receiving general anesthesia with 100% oxygen. After aspirating 0.2 ml aqueous humor under sterile conditions, the aqueous sample and a simultaneously drawn arterial blood sample were immediately analyzed using a blood gas analyzer. In part II the same procedures were performed in 10 patients after fitting a contact lens and patching the eye for 20 minutes (group IV and in 10 patients after transcorneal delivery of oxygen at a flow rate of 5 L/min (group V. Results: Mean aqueous PO2 in groups I, II and III was 112.3±6.2, 141.1±20.4, and 170.1±27 mmHg, respectively (P values <0.001 and mean arterial PO2 was 85.7±7.9, 184.6±46, and 379.1±75.9 mmHg, respectively (P values <0.001. Aqueous PO2 was 77.2±9.2 mmHg in group IV and 152.3±10.9 mmHg in group V (P values <0.001. There was a significant correlation between aqueous and blood PO2 (r=0.537, P<0.001. The contribution of atmospheric oxygen to aqueous PO2 was 23.7%. Conclusion: Aqueous oxygen tension is mostly dependent on the systemic circulation and in part on the atmosphere. Increasing inspiratory oxygen and transcorneal oxygen delivery both increase aqueous PO2 levels.

    Full Text Available In the paper, currently used methods for modeling the flow of the aqueous humor through eye structures are presented. Then a computational model based on rheological models of Newtonian and non-Newtonian fluids is proposed. The proposed model may be used for modeling the flow of the aqueous humor through the trabecular meshwork. The trabecular meshwork is modeled as an array of rectilinear parallel capillary tubes. The flow of Newtonian and non-Newtonian fluids is considered. As a results of discussion mathematical equations of permeability of porous media and velocity of fluid flow through porous media have been received.

    Aqueous humor is the transparent fluid found in the anterior chamber of the eye that provides the metabolic requirements to the avascular tissues surrounding it. Despite the fact that metabolomics could be a powerful tool in the characterization of this biofluid and in revealing metabolic signatures of common ocular diseases such as myopia, it has never to our knowledge previously been applied in humans. In this research a novel method for the analysis of aqueous humor is presented to show its application in the characterization of this biofluid using CE-MS. The method was extended to a dual platform method (CE-MS and LC-MS) in order to compare samples from patients with different severities of myopia in order to explore the disease from the metabolic phenotype point of view. With this method, a profound knowledge of the metabolites present in human aqueous humor has been obtained: over 40 metabolites were reproducibly and simultaneously identified from a low volume of sample by CE-MS, including among others, a vast number of amino acids and derivatives. When this method was extended to study groups of patients with high or low myopia in both CE-MS and LC-MS, it has been possible to identify over 20 significantly different metabolite and lipid signatures that distinguish patients based on the severity of myopia. Among these, the most notable higher abundant metabolites in high myopia were aminooctanoic acid, arginine, citrulline and sphinganine while features of low myopia were aminoundecanoic acid, dihydro-retinoic acid and cysteinylglycine disulfide. This dual platform approach offered complementarity such that different metabolites were detected in each technique. Together the experiments presented provide a whelm of valuable information about human aqueous humor and myopia, proving the utility of non-targeted metabolomics for the first time in analyzing this type of sample and the metabolic phenotype of this disease.

Methods: Twenty New Zealand rabbits were anesthetized intramuscularly with ketamine and xylazine and were then allowed to breathe room air. Using a gas blood analyzer, arterial blood and AH samples were analyzed for PO2, PCO2, and pH. Results: The mean arterial blood pressure was 87.14 ± 15.0 mmHg. The mean blood and AH PO2 were 95.18 ± 11.76 mmHg and 88.83 ± 9.92 mmHg, the mean blood and AH PCO2 were 25.86 ± 5.46 mmHg and 29.50 ± 5.36 mmHg, and the mean blood and AH pH were 7.38 ± 0.06 and 7.33 ± 0.09, respectively. Conclusion: Conclusions: The blood gas analyzer was easily employed to evaluate the aqueous humor in rabbits. When comparing the results of studies evaluating aqueous PO2, care should be taken to determine the methods used in these studies.

  6. Effect of excimer laser (Arf, 193 nm) on aqueous humor during photorefractive keratectomy biophysical and biochemical study

    International Nuclear Information System (INIS)

    Ultraviolet light (193 nm) produced by an excimer laser has been used to produce precise tissue ablation with minimal thermal damage to adjacent tissue. The present study was designed to investigate the effect of excimer laser during photo refractive keratectomy (PRK) on aqueous humor constituents and also the effect of antioxidant enzyme superoxide dismutase (SOD)- applied topically- on these changes if exist. Five groups of schenchilla rabbits were involved in this study, where four groups underwent corneal stromal ablation using argon fluoride excimer laser (Ar F, 193 nm). Two of these four groups were treated with superoxide dismutase intra operatively. The fifth group was used as control one. The obtained results revealed depletion of aqueous humor ascorbate and glutathione contents. Aqueous humor refractive index, cholesterol, phospholipids, malondialdehyde (MDA) and total protein were measured. In conclusion, the excimer laser can induce changes in aqueous humor constituents during PRK. These changes lasted at least for 24 hours and as the time increased to 4 weeks, these changes became limited. The use of exogenous SOD seems to exert beneficial effect on aqueous humor refractive index and total protein

    Purpose. The purpose of the study was to elucidate the role of transforming growth factor-beta 2 (TGF-β2) in the development of high myopic capsular contraction syndrome. Methods. Nineteen cases of capsular contraction syndrome, including 14 with high myopia, were collected, and their clinical data were reviewed. Aqueous humor and anterior capsular membranes were obtained during capsulotomy. Hematoxylin-eosin and immunohistochemical staining with anti-TGF-β2 antibody were performed on capsular membranes. TGF-β2 levels in aqueous humor were assayed using ELISA and western blot. Results. High myopia was significantly associated with the incidence of capsular contraction syndrome (odds ratio: 14.74, P myopia. Conclusions. High myopia is a risk factor for capsular contraction syndrome. Elevated TGF-β2 levels in high myopic cataract patients may play an important role in the pathogenesis of capsular contraction syndrome. PMID:26942002

    Purpose The objective of this study was to compare the pharmacokinetics of levofloxacin 1.5% and moxifloxacin hydrochloride 0.5% ophthalmic solutions in aqueous humor after multiple doses prior to cataract surgery. Methods Ninety-eight eyes underwent cataract surgery and met the requirements of PK analysis. Eligible eyes were randomly assigned in a 1:1 ratio to receive levofloxacin or moxifloxacin prior to cataract surgery and were randomized into one of four sampling time points (ie, 1, 2, 4, and 6 hour post-last dose). Randomization was investigator and laboratory-masked. Three days prior to cataract surgery, each patient instilled one drop of the assigned study medication into the operative eye four times daily. One aqueous humor specimen was collected from the eye at the randomized time point. Aqueous humor specimens were assayed for drug concentration using a validated liquid chromatography and tandem mass spectrometer. Results Concentrations of the drug in the aqueous humor, as described by mean Cmax and pooled AUC0–6 values, were greater for levofloxacin than moxifloxacin (Cmax: 1.43, 0.87 μg/ml, respectively, P=0.008; AUC0–6 6.1, 3.8 μg·min/ml, P<0.001 respectively). No treatment-emergent adverse events were reported. Conclusion Significantly greater drug exposures were attained in aqueous humor following the administration of levofloxacin 1.5% than moxifloxacin 0.5% ophthalmic solution. Achieving considerable higher drug concentration in the aqueous humor with levofloxacin 1.5% may demonstrate a greater potential for bacterial eradication. PMID:27194905

    Full Text Available Purpose. The purpose of the study was to elucidate the role of transforming growth factor-beta 2 (TGF-β2 in the development of high myopic capsular contraction syndrome. Methods. Nineteen cases of capsular contraction syndrome, including 14 with high myopia, were collected, and their clinical data were reviewed. Aqueous humor and anterior capsular membranes were obtained during capsulotomy. Hematoxylin-eosin and immunohistochemical staining with anti-TGF-β2 antibody were performed on capsular membranes. TGF-β2 levels in aqueous humor were assayed using ELISA and western blot. Results. High myopia was significantly associated with the incidence of capsular contraction syndrome (odds ratio: 14.74, P<0.001, 95% CI: 5.29–41.05. Histopathological analysis revealed proliferation of fibroblast-like lens epithelial cells on the shrunken anterior capsule, labeled with TGF-β2 antibodies. ELISA and Western blot showed higher levels of TGF-β2 in aqueous humor of patients with capsular contraction syndrome and high myopia. Conclusions. High myopia is a risk factor for capsular contraction syndrome. Elevated TGF-β2 levels in high myopic cataract patients may play an important role in the pathogenesis of capsular contraction syndrome.

    An intact ciliary epithelial bilayer has been isolated from the rabbit eye by perfusion, microsurgical dissection, and recovery techniques. Vital subcellular organelles and intercellular junctions of this epithelial bilayer preparation are very well preserved. The total electrical resistance of the epithelial bilayer is 350 ohms, and the transepithelial potential is 650 microV, nonpigmented epithelium side negative. The electrical resistance is reduced by 0.2 mM EGTA and the transepithelial potential reduced by 0.1 mM ouabain. Bicarbonate depletion at a constant pH of 7.4 rapidly and significantly reduces the transepithelial potential. Carbonic anhydrase inhibitors decrease transmembrane potential by as much as 30%. These morphologic and physiologic experiments authenticate the validity of this bilayered epithelial preparation for future use in detailed studies of the mechanism of aqueous humor formation.

Phase 1 involved construction of the sensor. This was broadly based on the fundamental design of a typical Schiotz tonographer with a series of improvements, including corneal indentation, which was converted to an electrical signal via a linear variable differential transducer, an analog signal which was converted to digital via ADC circuitry, and digital data acquisition and processing which was made possible by a serial port interface. Phase 2 comprised development of software for automated assessment of the outflow facility. Automated outflow facility assessment incorporated a series of fundamental improvements in comparison with traditional techniques, including software-based filtering of ripple noise and extreme variations, rigidity impact analysis, and evaluation of the impact of patient age, central corneal thickness, and ocular axial length. Phase 3 comprised characterization and validation of DAHOM, for which we developed an experimental setup using porcine cadaver eyes. DAHOM’s repeatability was evaluated by means of Cronbach’s alpha and intraclass correlation coefficient. The level of agreement with a standard Schiotz tonographer was evaluated by means of paired t-tests and Bland-Altman analysis in human eyes.Results: The experimental setup provided the necessary data for the characterization of DAHOM. A fourth order polynomial equation provided excellent fit (R square >0.999. DAHOM demonstrated high repeatability (Cronbach’s alpha ≥0.997; intraclass correlation coefficient ≥0.987 and an adequate level of

  13. Study on the aqueous humor contents of IL-1β and IL-6 in rabbits after extracapsular extraction of lens

    International Nuclear Information System (INIS)

    Objective: To explore the relationship between the development of posterior capsular opacification and the aqueous humor contents of IL-1β and IL-6 after extracapsular extraction of lens in rabbits. Methods: Extracapsular extraction of lens was performed in 30 New Zealand rabbits. Aqueous humor contents of IL-1β and IL-6 were repeatedly determined with RIA and ophthal-moscopic as well as slit-lamp examination were repeatedly performed to detect any posterior capsular opacification developed on dl, d3, 1w, 2w, 1 month, 3 month posteperatively. Results: The aqueous humor contents of IL-1β and IL-6 increased gradually after operation, reached the peak on d7-d14, then gradually returned to within normal range by 2nd or 3rd month. Beginning from one month post-operatively, posterior capsular opacification was observed in some rabbits. By the end of 3rd month, Grade I opacification was developed in 5 rabbits, Grade H in 9 rabbits with Grade III (fundus view obliterated) in 14 rabbits. Peak IL-1β and IL- 6 content values were positively correlated with grading of future opacification. Conclusion: IL-1β and IL-6 might play important roles in the development of posterior capsular opacification after lens extraction in rabbits. (authors)

    Full Text Available Background and Objective: The concentration of ethanol measured in postmortem blood needs to be interpreted as to whether the person who had consumed alcohol has exceeded some threshold limit. However, interpreting postmortem BAC (Blood Alcohol Concentration results and drawing correct conclusions about ante mortem levels is fraught with difficulties as under some circumstances alcohol might be produced after death by microbial activity.Subjects and Methods: In the case of ethanol, the blood samples should be taken from a femoral vein and whenever possible additional specimens, such as urine and vitreous humor (VH, should also be obtained and sent for analysis to be able to have the best interpretationResults: 167 Specimens of femoral vein blood and vitreous humor were analyzed. In this study, direct injection and gas-chromatographic techniques were employed to quantitate the ethanol concentrations. These two concentrations were then compared and the BAC/VHAC (Viterous Humor Alcohol Concentration ratio was evaluated.Among these specimens, there were 142 cases in which we have found ethanol in blood but not in vitreous humor. Also we have found 2 cases by positive VHAC but negative BAC. The average blood ethanol concentration was 61.5 mg/dLit while the average ethanol vitreous humor concentration was 127 mg/dLit. However, the ratio was measured as 0.7.Conclusion: The similarity in the results of the post mortem cases reinforces the assertion that co analysis of vitreous humor and blood is important to interpret post mortem results

    Tacrolimus (FK506) was used to prevent corneal allograft rejection in patients who were resistant to steroids and cyclosporine. However, the formulation for FK506 ocular delivery remained a challenge due to the drug's high hydrophobicity, high molecular weight, and eye's physiological and anatomical constraints. The aim of this project is to develop an ocular delivery system for FK506 based on a combined strategy of niosomes and mucoadhesive hyaluronic acid (HA), i.e., FK506HA-coated niosomes, which exploits virtues of both niosomes and HA to synergistically improve ophthalmic bioavailability. The FK506HA-coated niosomes were characterized with particle size, zeta potential, and rheology behavior. Mucoadhesion of FK506HA-coated niosomes to mucin was investigated through surface plasmon resonance in comparison with non-coated niosomes and HA solution. The results showed that niosomes possessed adhesion to mucin, and HA coating enhanced the adhesion. The in vivo precorneal retention was evaluated in rabbit, and the results showed that HA-coated niosomes prolonged the residence of FK506 significantly in comparison with non-coated niosomes or suspension. Aqueous humor pharmacokinetics test showed that area under curve of HA-coated niosomes was 2.3-fold and 1.2-fold as that of suspension and non-coated niosomes, respectively. Moreover, the synergetic corneal permeability enhancement of the hybrid delivery system on FK506 was visualized and confirmed by confocal laser scanning microscope. Overall, the results indicated that the hybrid system facilitated FK506 ocular delivery on mucoadhesion, precorneal retention, aqueous humor pharmacokinetics and transcorneal permeability. Therefore, HA-coated niosomes may be a promising approach for ocular targeting delivery of FK506. PMID:26820107

    Full Text Available Sankarathi Balaiya Sandeep Grover Ravi K Murthy Kakarla V ChalamDepartment of Ophthalmology, University of Florida College of Medicine, Jacksonville, FL, USAPurpose: Aqueous levels of vascular endothelial growth factor (VEGF can be a surrogate marker of intraocular VEGF activity and a measure of efficacy of anti-VEGF treatment in a variety of vasoproliferative retinal disorders, including diabetic retinopathy, age-related macular degeneration, and central retinal vein occlusion. Measurement of the VEGF level may be adversely affected by premeasurement variables, such as freezing and delay, in sample analysis. We aim to evaluate the effect of storage and delayed measurement of human aqueous VEGF levels in these conditions.Methods: Aqueous samples collected from patients receiving intravitreal injection of bevacizumab for various retinal diseases were divided into two groups. In Group 1, the VEGF levels were analyzed on the same day; in Group 2, the VEGF levels were analyzed after 21 days of freezer storage (-80°C using immunobead assay. Statistical comparison using a paired t-test was performed between the two groups.Results: Thirty-one aqueous humor samples were collected, and the VEGF concentration for fresh samples was 7.8 ± 5.9 pg/mL (mean ± SD compared to 6.5 ± 6.0 pg/mL in frozen samples, resulting in a statistically significant difference (P = 0.03.Conclusions: Accurate measurement of the VEGF level is a vital component of clinical decision-making. Delayed analysis of VEGF levels in aqueous samples may result in significant sample degradation and lower levels of measured VEGF.Keywords: VEGF level, aqueous humor, immunobead assay, VEGF storage

    Allergy history has been consistently inversely associated with glioma risk. Two serologic markers, soluble CD23 (sCD23) and soluble CD14 (sCD14), are part of the innate and adaptive humoral immune systems and modulate allergic responses in opposite directions, with sCD23 enhancing and sCD14 blunting inflammatory responses. We measured sCD23 and sCD14 in serum from blood that was drawn at a single time point from 1,079 glioma patients postdiagnosis and 736 healthy controls. Glioma was strongly associated with high sCD14 [highest versus lowest quartile odds ratio (OR), 3.94; 95% confidence interval (95% CI), 2.98-5.21] and low sCD23 (lowest versus highest quartile OR, 2.5; 95% CI, 1.89-3.23). Results were consistent across glioma histologic types and grades, but were strongest for glioblastoma. Whereas temozolomide treatment was not associated with either sCD14 or sCD23 levels among cases, those taking dexamethasone had somewhat lower sCD23 levels than those not taking dexamethasone. However, sCD23 was associated with case status regardless of dexamethasone treatment. These results augment the long-observed association between allergies and glioma and support a role for the innate and adaptive humoral functions of the immune system, in particular immunoregulatory proteins, in gliomagenesis.

    2007-02-01

    The reduced outflow rate caused by the increased resistance through trabecular meshwork (TM) has been thought to be the main reason for elevated intraocular pressure (IOP). It has been demonstrated that femtosecond laser pulses tuned to 1.7 μm wavelength can create the partial thickness channel in the sclera in ex vivo human eyes [1] and aqueous outflow can be increased by these channels in porcine eyes [2]. It was also shown that the outflow rate is reduced over time in ex vivo human eyes [3]. Therefore, the control experiment without laser treatment at the same condition was conducted and showed that outflow was reduced by 1.5 +/- 0.8 μl/min at 15mmHg and 1.8 +/- 1.0 μl/min at 25mmHg. However, the outflow rate increased by 0.26 μl/min at 15mmHg and 0.15 μl/min at 25mmHg after the partial thickness channel was created, meaning the amount of increased outflow rate might be more than measured considering the outflow reduction in control experiment. We suggest that the femtosecond laser created partial thickness channel can increase the outflow rate and delay the progression of glaucoma.

    The objective of this study was to evaluate the kinetics of varicella-zoster virus (VZV) loads using quantitative PCR (qPCR) in patients treated for acute retinal necrosis (ARN). Six patients (52 ± 13 years old) with ARN syndrome were consecutively studied. Aqueous humor (AH) was sampled from both eyes of all patients for qPCR evaluation. The patients were treated with intravenous acyclovir and intravitreal injections of antiviral drugs. The mean follow-up time was 17.6 ± 16.4 months. Main outcome measures were the numbers of viral genome copies in the AH, assessed using real-time qPCR with hydrolysis probe technology with a threshold of detection of 200 copies/ml. Two main portions of the viral load curves were observed for each patient: a plateau phase (27.8 ± 24.9 days) and a decrease in the number of viral genome copies. The mean baseline viral load was 3.4 × 10(7) ± 4.45 × 10(7) copies/ml (6 × 10(6) to 1.2 × 10(8) copies/ml). The viral load decreased according to a logarithmic model, with a 50% reduction obtained in 3 ± 0.7 days. There was a significant viral load (>102 copies/ml) at 50 days after the onset of treatment, despite antiviral drugs. qPCR use demonstrated reproducible VZV DNA kinetics with a two-phase evolution: a plateau followed by a logarithmic decrease. These data suggest that high-dosage antiviral therapy administered for the conventional 10-day duration is insufficient for most patients. This series of patients responded with a similar decrease in viral load once treatment was initiated, and the data from these patients may be used to predict the responses of future patients.

    In this work, a sensitive, selective, accurate and precise LC-MS/MS method has been developed for the simultaneous determination of an anti-glaucoma ß-blocker, timolol maleate (TIM) with other co-administered anti-glaucoma drugs of different classes, namely; dorzolamide hydrochloride (DOR), brinzolamide (BRZ) and brimonidine tartrate (BRM) in rabbit aqueous humor (AH) using eslicarbazepine as an internal standard (IS). Liquid-liquid extraction was used for the purification and pre-concentration of analytes from rabbit AH matrix. The chromatographic separation was achieved using a mobile phase consisting of 10mM ammonium formate pH=7: methanol: acetonitrile (5: 50: 45, v/v/v) in isocratic mode of elution at a flow rate of 0.8mL/min on an INERTSIL(®) C18 ODS-3 column (150mm×4.6mm, 3.5μm). The method was operated using electrospray ionization source in the positive ionization mode prior to detection by multiple reaction monitoring (MRM) at the following transitions: m/z 317.2→261.0 for TIM, m/z 325.1→199.0 for DOR, m/z 384.2→281.0 for BRZ, m/z 292.1→212.0 for BRM and m/z 255.0→237.0 for IS. The separation was done in only 3min and the lower limit of quantitation (LLOQ) was (50ng/ml) for all cited drugs. A detailed validation of the bio-analytical method was performed as mentioned in US-FDA and EMA guidelines and the standard calibration curves were found to be linear in the range (50-5000ng/ml) for all drugs with good mean regression coefficient for all drugs.

    Aqueous precursors tailored for the deposition of thin film materials are desirable for sustainable, simple, low energy production of advanced materials. Yet the simple practice of using aqueous precursors is complicated by the multitude of interactions that occur between ions and water during dehydration. Here we use lithium polyoxoniobate salts to investigate the fundamental interactions in the transition from precursor cluster to oxide film. Small-angle X-ray scattering of solutions, total X-ray scattering of intermediate gels, and morphological and structural characterization of the lithium niobate thin films reveal the atomic level transitions between these states. The studies show that (1) lithium–[H{sub 2}Nb{sub 6}O{sub 19}]{sup 6−} has drastically different solution behaviour than lithium–[Nb{sub 6}O{sub 19}]{sup 8−}, linked to the precursor salt structure (2) in both compositions, the intermediate gel preserves the polyoxoniobate clusters and show similar local order and (3) the morphology and phases of deposited films reflect the ions behaviour throughout the journey from cluster solution to metal oxide. - Graphical abstract: Aqueous lithium polyoxoniobate salts were used to prepare lithium niobate (LiNbO{sub 3}) thin films. Fundamental studies were performed to investigate the interactions in the transition from precursor cluster to the oxide film. It was found that acid–base and ion-association chemistries of the aqueous and gel systems significantly affect the key processes in this atom-level journey. - Highlights: • Lithium polyoxoniobate clusters were synthesized with control over Li:Nb ratio as precursors for LiNbO{sub 3} films. • X-ray scattering studies in solution and the solid-state revealed differences controlled by Li:Nb ratio. • Film deposition studies revealed phase, composition and morphology is controlled by Li:Nb ratio. • Cluster to film transformation was revealed using total X-ray scattering and TGA.

    This study assessed the concurrent and prospective (fall to spring) associations between four different humor styles to assess the degree to which stable friendships are characterized by similarity, and to assess whether best friends' humor styles influence each other's later use of humor. Participants were aged 11-13 years, with 87 stable, reciprocal best friend dyads. Self-report assessments of humor styles were completed on both occasions. Results indicated that there was no initial similarity in dyads' levels of humor. However, dyads' use of humor that enhances interpersonal relationships (Affiliative humor) became positively correlated by spring. Additionally, young people's use of this humor style was positively associated with their best friend's later use of the same. No such effects were present for humor which was aggressive, denigrating toward the self, or used to enhance the self. These results have clear implications for theories of humor style development, highlighting an important role for Affiliative humor within stable friendship dyads. PMID:26580553

    Full Text Available Abstract Background The aqueous humor (AH, a liquid of the anterior and posterior chamber of the eye, comprises many proteins with various roles and important biological functions. Many of these proteins have not been identified yet and their functions in AH are still unknown. Recently, our laboratory published the protein database of AH obtained from healthy rabbits which expanded known protein identifications by 65%. Our present study extends our previous work and analyses AH following two types of cataract surgery incision procedures (clear corneal and limbal incisions by using two dimensional gel electrophoresis (2-DE and liquid chromatography tandem mass spectrometry (LC-MS/MS. Although both incision protocols are commonly used during cataract surgeries, the difference in protein composition and their release into AH following each surgery has never been systematically compared and remains unclear. The first step, which is the focus of this work, is to assess the scale of the protein change, at which time does maximum release occurs and when possible, to identify protein changes. Results Samples of AH obtained prior to surgery and at different time points (0.5, 2, 12, 24 and 48 hours following surgery (n = 3/protocol underwent protein concentration determination, 2-DE and LC-MS/MS. There was a large (9.7 to 31.2 mg/mL and rapid (~0.5 hour influx of proteins into AH following either incision with a return to baseline quantities after 12 hours and 24 hours for clear corneal and limbal incision, respectively. We identified 80 non-redundant proteins, and compared to our previous study on healthy AH, 67.5% of proteins were found to be surgery-specific. In addition, 51% of those proteins have been found either in clear corneal (20% or limbal incision (31% samples. Conclusions Our results imply that a mechanism of protein release into AH after surgery is a global response to the surgery rather than increase in amount of protective proteins found

    Endogenous enzymes such as phytase have been widely used in swine production to increase phosphorus, amino acid and energy availability from feeds. This study aimed to evaluate the immune system through quantification of blood components associated to iron metabolism and determine humoral immune response elements in pigs fed phytase-added diets without micro minerals and vitamins and partial or total deletion of inorganic phosphorus. Forty-eight crossbred females with initial weight of 60 kg were randomly sorted into six groups of eight animals each, as follows: G1 -standard (complete ration (control group; G2 - standard ration except that micromineral and vitamin supplement was deleted; G3 - group 2 ration with phytase, G4 - group 2 ration less 1/3 of inorganic P with phytase, G5 -  group 2 ration less 2/3 of inorganic P with phytase and G6 - group 2 ration without inorganic P with phytase. Statistical difference (p>0,05 was not recorded neither in white cells and platelet counts nor hemoglobin, serum iron levels, considering all the animals in all treatments. Nevertheless, pigs up to 100 kg that consumed diet without micro minerals and vitamins, total deletion of inorganic P and phytase addition presented increased ferritin levels (p>0,05 when compared to animals fed similar diet with inorganic phosphorus and phytase. The enzyme guaranteed maintenance of iron stocks even in the absence of supplementation. Such difference was not recorded with 120-kg animals fed similar rations. Average total protein, IgG and IgM levels were not influenced by phytase, mineral and vitamin supplementation or inorganic phosphorus levels. The results demonstrate that decrease of inorganic phos-phorus, withdrawal of vitamin and mineral supplements and phytase addition in diets of finishing pigs do not lead to significant changes in hematological, biochemical and humoral immune response parameters.

  20. Sense of Humor, Stable Affect, and Psychological Well-Being

    2014-08-01

    Full Text Available A good sense of humor has been implicated as a quality that could contribute to psychological well-being. The mechanisms through which sense of humor might operate include helping to reappraise threats, serving as a character strength, or facilitating happiness. The current research attempts to integrate these possibilities by examining whether a good sense of humor might operate globally by helping to maintain a more stable positive affect. Stable positive affect has been shown to facilitate more effective problem solving and to build resilience. However, not all humor is adaptive humor, so we also examine the roles that different styles of humor use might play. Individual differences in humor styles were used to predict stable levels of affect. Then, in a longitudinal design, humor styles and stable affect were used to predict subsequent resilience and psychological health. The results indicated that stable affect was related to resilience and psychological well-being, and that a sense of humor that involves self-enhancing humor, humor based on maintaining a humorous perspective about one’s experiences, was positively related to stable positive affect, negatively related to stable negative affect, and was mediated through stable affect in influencing resilience, well-being and distress. Thus, while a good sense of humor can lead to greater resilience and better psychological health, the current results, focusing on stable affect, find only self-enhancing humor provides reliable benefits.

  4. Instructional scientific humor in the secondary classroom

    Science.gov (United States)

    Wizner, Francine

    This study is an examination of the manner in which educators employ scientific content humor and how that humor is perceived by their students. Content humor is a useful strategy in drawing the attention of students and improving their receptivity toward scientific information. It is also a useful tool in combating the growing distractions of the electronic classroom. Previous studies have found that humor has a positive effect on knowledge, memory, and understanding. However, few studies have been conducted below the undergraduate level and mainly quantitative measures of student recall have been used to measure learning. This study employed multiple data sources to determine how two secondary biology teachers used humor in order to explain scientific concepts and how their students perceived their teachers' use of scientific instructional humor. Evidence of student humor reception was collected from four students in each of the two classes. All of the scientific instructional humor used in the studied classrooms was cognitive in nature, varying among factual, procedural, conceptual, and metacognitive knowledge. Teachers tended to use dialogic forms of humor. Their scientific humor reflected everyday experiences, presented queries, poked fun at authority, and asked students to search out new perspectives and perform thought experiments. Teachers were the primary actors in performing the humorous events. The events were sometimes physical exaggerations of words or drawings, and they occurred for the purpose of establishing rapport or having students make connections between scientific concepts and prior knowledge. Student perceptions were that teachers did employ humor toward instructional objectives that helped their learning. Helping students become critical thinkers is a trademark of science teachers. Science teachers who take the risk of adopting some attributes of comedians may earn the reward of imparting behaviors on their students like critical thinking

    Full Text Available Pulpitis is an inflammation process on dental pulp tissue, and usually as the continuous of caries. The microorganism in the caries is a potential immunogenic triggering the immune respons, both humoral and celluler immune responses. The aim of this research is to explain the humoral immune response changes in the dental pulp tissues of pulpitis. This research was done on three group samples: Irreversible pulpitis, Reversible pulpitis and sound teeth as the control group. The result showed that there were three pulpitis immunopathologic patterns: the sound teeth immunopathologic pattern showing a low humoral immune response, in a low level of IgG, IgA and IgM, the reversible pulpitis pattern showing that in a higher humoral immune response, IgG and IgA decreased but IgM increased, the irreversible pulpitis pattern showing that IgG and IgM increased, but it couldn't be repaired although it has highly immunity, and it showed an unusually low level of IgA. This low level of IgA meant that irreversible pulpitis had a low mucosal immunity.

    Background Interleukin (IL)-1β may effectively decrease introcular pressure (IOP) when administered by subconjunctival injection in normal rabbit. However, IL-1β is a large molecular agent and an inflammation factor. The aim of this study was to evaluate the penetrability of IL-1β, and the concentrations of both tumor necrosis factor (TNF)-α and IL-6 in the aqueous humor of normal rabbits treated with IL-1β.Methods A total of 170 rabbits were used in the study and were assigned to several different treatment groups as follows: 125 of the rabbits were assigned to two groups. In one group, 33 rabbits were injected subconjunctivally with IL-1β and 39 were injected with saline alone. In the other group, 27 rabbits were given eye drops containing IL-1β (400 ng/ml) and 26 were given saline alone. Aqueous humor (AH) was drawn and the concentration of IL-1β within the fluid measured. The IOP was measured in another six rabbits after administration of eye drops containing IL-1β (400 ng/ml). A further 20 rabbits were assigned to 3 groups as follows: eight untreated normal controls; six injected subconjunctivally with IL-1β; and six injected subconjunctivally with saline alone. AH was drawn and the concentration of TNF-α in the fluid was measured. Another 19 rabbits were assigned to 3 groups as follows: seven untreated normal controls; and six injected subconjunctivally with IL-1β; and six injected subconjunctivally with saline alone. AH was drawn and the concentration of IL-6 in the fluid measured. Measurement of cytokine concentration was by radio-immunoassay in all cases.Results The IL-1β concentration in the AH was higher in those animals in which it had been administered subconjunctivally (P 0.05). The administration of IL-1β in the form of eye drops had little effect upon lOP reduction. Lower TNF-α concentrations were seen in the AH after the subconjunctival administration of IL-1β, but the concentration of IL-6 was the same as in the normal controls

  9. Uranium recovery from low-level aqueous sources

    International Nuclear Information System (INIS)

    The aqueous sources of soluble uranium were surveyed and evaluated in terms of the uranium geochemical cycle in an effort to identify potential unexploited resources. Freshwater sources appeared to be too low in uranium content to merit consideration, while seawater, although very dilute (approx. 3.3 ppB), contains approx. 4 x 109 metric tons of uranium in all the world's oceans. A literature review of recent publications and patents concerning uranium recovery from seawater was conducted. Considerable experimental work is currently under way in Japan; less is being done in the European countries. An assessment of the current state of technology is presented in this report. Repeated screening programs have identified hydrous titanium oxide as the most promising candidate absorbent. However, some of its properties such as distribution coefficient, selectivity, loading, and possibly stability appear to render its use inadequate in a practical recovery system. Also, various assessments of the energy efficiency of pumped or tidal power schemes for contacting the sorbent and seawater are in major disagreement. Needed future research and development tasks are discussed. A fundamental sorbent development program to greatly improve sorbent properties would be required to permit practical recovery of uranium from seawater. Major unresolved engineering aspects of such recovery systems are also identified and discussed

    Full Text Available Introduction: Zinc deficiency causes abnormalities in immune response. In chronic hemodialysis (HD and continuous ambulatory peritoneal dialysis (CAPD patients, impaired immune responses to vaccination have been reported. Therefore, we performed a study to determine the correlation between serum zinc levels and immune response to hepatitis B vaccination in patients on dialysis. Methods: A cross-sectional study including 95 CRF patients on dialysis (70 HD and 25 CAPD, (63 male and 32 female with three dose regimens of vaccination against HBV was performed. Results: Four months after vaccination, there were 34 (36% patients with sufficient HBs Antibody response (HBs Ab≥ 10 mU/mL and 61 ( 64% patients with insufficient HBs antibody response( HBs Ab< 10mU/mL . The mean serum zinc level was 23.35±3.87 micmol/L (13.20-33 micmol/L. The mean serum zinc concentration was significantly higher in patients with sufficient HBs antibody level than patients with insufficient HBs antibody levels ( 24.94±4.17 versus 22.15±3.46, P= 0.005 . In logistic regression analysis, independent variables that correlated with sufficient HBs Ab level ≥ 10 mU/mL included higher mean serum zinc level [OR=1.44 (1.02-2.02, P=0.006 ] and female gender [OR=1.8 (1.01-4.01, P=0.048] . Factors found to be insignificant included type of dialysis, age, diabetes mellitus as a cause of ESRD, serum creatinine and albumin levels. Conclusion: We conclude that failure to respond to HBV vaccination is significantly related to a low levels of serum zinc. However, clinical trial studies should be performed in order to confirm this finding.

    By looking at stand-up comedian Russell Peters’s show “The Green Card Tour”, we seek an understanding of how sociolinguistics and humor correlates and are applied for comedic effect. In order to achieve the latter, this project will firstly attempt to explain sociolinguistics and humor in relation to each other. Later, those concepts will be applied to the chosen sections within the The Green Card Tour, specifically revolving around how Russell Peters achieves comedic effect...

  12. A Low Level Radioactivity Monitor for Aqueous Waste

    International Nuclear Information System (INIS)

    A system is described for continuous monitoring of very low levels of radioactivity in waste water containing typically 3.5 g/l dissolved solids. Spray evaporation of the water enables the dissolved solids to be recovered in the form of an aerosol and collected on a filter tape where the radioactivity is measured by a radiation detector. The advantage of this method compared with a direct measurement is that the attenuating effect of the water is removed and thus greater sensitivity is obtained. Compensation for background and any contamination is achieved by feeding distilled water to the aerosol generator every alternate sampling period and recording the count difference between two successive sampling periods . A printed record of the totalised count difference is obtained once per hour during the integration time of one month. For β radioactivity the minimum values of specific activity measurable extend from 1 x 10-6 Ci/m3 to 6 x 10-8 Ci/m depending on the B end-point energy in the range 167 KeV to 2.26 MeV. The estimated minimum measurable specific activity is 6 x 10-8 Ci/m3

    Bronchiectasis occurs in patients with immunodeficiency and fungal hypersensitivity disorders. To assess the prevalence of abnormal humoral immune parameters in bronchiectasis, a retrospective study was carried out on sera from 30 patients. Studies included immunoglobulin quantitation and specific antibody to fungal species. Eleven patients were found to have immunodeficiency (nine with panhypoglobulinemia and two with selective IgM deficiency). Six patients had elevations of serum IgA and four patients had elevations of serum IgE. Six patients had elevated total antibody to Aspergillus or Candida species and six had precipitin bands to one or more fungal antigens. This study indicates that immunodeficiency is prevalent and plays a causative role in some patients with bronchiectasis. Hypersensitivity reactions to Aspergillus, Candida, and other ubiquitous environmental fungi may also play an etiopathogenic role in this disease (bronchiectasis, humoral immunity, immunodeficiency).

    In this paper we report the results of testosterone manipulation in the blood of male Campbell dwarf hamsters Phodopus campbelli Thomas, 1905 through castration, followed by testosterone treatment. Under these conditions, we studied antibody production rates in response to injection with sheep red blood cells (SRBC). It was shown that castration induced a dramatic decrease in blood testosterone but had no effect on the humoral response to SRBC. Males that received a testosterone compound with a long-lasting action (omnadren) exhibited a poor response to SRBC following re-exposure in the context of elevated testosterone compared to castrated males inoculated with an oil base of the drug.

    Submicrorepresentations (SMR) could be an important element, not only for explaining the experimental observations to students, but also in the process of evaluating students’ knowledge and identifying their chemical misconceptions. This study investigated the level of students’ understanding of the solution concentration and the process of dissolving ionic and molecular crystals at particulate level, and identifies possible misconceptions about this process. Altogether 408 secondary school students (average age 16.3) participated in the study. The test of chemical knowledge was applied and the analysis of four selected problems related to drawing SMRs in solution chemistry is presented. Selected students were also interviewed in order to gain more detailed data about their way of solving problems comprised in the knowledge test. The average achievement on solution chemistry items was only 43%. It can be concluded from the results that students have different misconceptions about arrangements of solute particles in the solution and presentation of its concentration at particulate level. Students show quite low achievement scores on the problem regarding drawing the SMR of ionic substance aqueous solution (7.6% correct answers) and even lower ones on the problem regarding drawing the SMR of diluted and saturated aqueous solutions of molecular crystal (no completely correct answers). It can be also concluded that many different misconceptions concerning the particulate level of basic solution chemistry concepts can be identified. In the conclusion some implications for teaching to reach a higher level of understanding of solution chemistry are proposed.

    Humor plays an essential role in human interactions. Precisely what makes something funny, however, remains elusive. While research on natural language understanding has made significant advancements in recent years, there has been little direct integration of humor research with computational models of language understanding. In this paper, we propose two information-theoretic measures-ambiguity and distinctiveness-derived from a simple model of sentence processing. We test these measures on a set of puns and regular sentences and show that they correlate significantly with human judgments of funniness. Moreover, within a set of puns, the distinctiveness measure distinguishes exceptionally funny puns from mediocre ones. Our work is the first, to our knowledge, to integrate a computational model of general language understanding and humor theory to quantitatively predict humor at a fine-grained level. We present it as an example of a framework for applying models of language processing to understand higher level linguistic and cognitive phenomena. PMID:26235596

  4. Energy Level Alignment at Aqueous GaN and ZnO Interfaces

    Electronic energy level alignment at semiconductor-electrolyte interfaces is fundamental to electrochemical activity. Motivated in particular by the search for new materials that can be more efficient for photocatalysis, we develop a first principles method to calculate this alignment at aqueous interfaces and demonstrate it for the specific case of non-polar GaN and ZnO interfaces with water. In the first step, density functional theory (DFT) based molecular dynamics is used to sample the physical interface structure and to evaluate the electrostatic potential step at the interface. In the second step, the GW approach is used to evaluate the reference electronic energy level separately in the bulk semiconductor (valence band edge energy) and in bulk water (the 1b1 energy level), relative to the internal electrostatic energy reference. Use of the GW approach naturally corrects for errors inherent in the use of Kohn-Sham energy eigenvalues to approximate the electronic excitation energies in each material. With this predicted interface alignment, specific redox levels in water, with potentials known relative to the 1b1 level, can then be compared to the semiconductor band edge positions. Our results will be discussed in the context of experiments in which photoexcited GaN and ZnO drive the hydrogen evolution reaction.

    We have developed a first principles method to calculate the energy level alignment between semiconductor band edges and reference energy levels at aqueous interfaces. This alignment is fundamental to understand the electrochemical characteristics of any semiconductor electrode in general and the potential for photocatalytic activity in particular. For example, in the search for new photo-catalytic materials, viable candidates must demonstrate both efficient absorption of the solar spectrum and an appropriate alignment of the band edge levels in the semiconductor to the redox levels for the target reactions. In our approach, the interface-specific contribution to the electrostatic step across the interface is evaluated using density functional theory (DFT) based molecular dynamics to sample the physical interface structure and the corresponding change in the electrostatic potential at the interface. The reference electronic levels in the semiconductor and in the water are calculated using the GW approach, which naturally corrects for errors inherent in the use of Kohn-Sham energy eigenvalues to approximate the electronic excitation energies in each material. Taken together, our calculations provide the alignment of the semiconductor valence band edge to the centroid of the highest occupied 1b1 level in water. The known relationship of the 1b1 level to the normal hydrogen electrode completes the connection to electrochemical levels. We discuss specific results for GaN, ZnO, and TiO2. The effect of interface structural motifs, such as different degrees of water dissociation, and of dynamical characteristics, will be presented together with available experimental data.

  6. Application of biomass for the sorption of radionuclides from low level Purex aqueous wastes

    International Nuclear Information System (INIS)

    Microbial biomass have been found to be good biological adsorbents for radioactive nuclides such as uranium and thorium with comparatively easy desorption and recovery. Based on this, sorption studies have been carried out to assess the feasibility of using biomass Rhizopus arrhizus (RA) for the removal of radionuclides present in Purex low level waste streams. Biomass Rhizopus arrhizus (RA) appears effective for the removal of actinides and fission products from low level Purex plant waste/effluent solutions. Maximum sorption for uranium and plutonium is observed at 6-7 pH whereas for Am, Eu, Pm, Ce and Zr the sorption is maximum at pH 2 with high D values and fast kinetics in both cases. Sorption for Ru and Cs are negligible. Sorbed nuclides are recoverable by elution with 1 M HNO3, on once through basis. The method can be used for treating the evaporator condensates from the plant and the hold-up delay tank solution. The sodium nitrate salt concentration in the aqueous solution beyond 0.14 M seriously affects the metal uptake. The results from column experiments indicate a limited loading capacity in terms of mg of Am/U/Pu etc. per gm of RA. However, as the Purex low level effluents contain only trace level activities whose absolute ionic concentrations are much lower, the capacities observed with the present form of biomass may still be satisfactory

    We investigate redox levels in aqueous solution using a combination of ab initio molecular dynamics (MD) simulations and thermodynamic integration methods. The molecular dynamics are performed with both the semilocal Perdew-Burke-Ernzerhof functional and a nonlocal functional (rVV10) accounting for van der Waals (vdW) interactions. The band edges are determined through three different schemes, namely, from the energy of the highest occupied and of the lowest unoccupied Kohn-Sham states, from total-energy differences, and from a linear extrapolation of the density of states. It is shown that the latter does not depend on the system size while the former two are subject to significant finite-size effects. For the redox levels, we provide a formulation in analogy to the definition of charge transition levels for defects in crystalline materials. We consider the H{sup +}/H{sub 2} level defining the standard hydrogen electrode, the OH{sup −}/OH{sup ∗} level corresponding to the oxidation of the hydroxyl ion, and the H{sub 2}O/OH{sup ∗} level for the dehydrogenation of water. In spite of the large structural modifications induced in liquid water, vdW interactions do not lead to any significant structural effect on the calculated band gap and band edges. The effect on the redox levels is also small since the solvation properties of ionic species are little affected by vdW interactions. Since the electronic properties are not significantly affected by the underlying structural properties, it is justified to perform hybrid functional calculations on the configurations of our MD simulations. The redox levels calculated as a function of the fraction α of Fock exchange are found to remain constant, reproducing a general behavior previously observed for charge transition levels of defects. Comparison with experimental values shows very good agreement. At variance, the band edges and the band gap evolve linearly with α. For α ≃ 0.40, we achieve a band gap, band

    The authors proposed that item selection during shopping is based on brand name recognition rather than recall. College students rated advertisements and news stories of a simulated radio program for level of amusement (orienting activity) before participating in a surprise recognition test. Humor level of the advertisements was varied systematically, and content was controlled. According to signal detection analysis, humor did not affect the strength of recognition memory for brand names (nonsense units). However, brand names and product types were significantly more likely to be associated when appearing in humorous advertisements than in nonhumorous advertisements. The results are compared with prior findings concerning humor and recall. PMID:11506048

    Full Text Available Problem statement: This study is to provide an overview discussion on the issue of humor management of within organizations. Although there are limits to which a work environment can be relaxed through humor or any other device, bonding through humor can be an important device within an organization whereby unity and common purpose are realized. Types of humor in the workplace can include puns, slapstick, jokes and anecdotes and teasing. Humor is also an important device for dealing with change. Approach: The literature review and arguments were conducted to identify the function, importance and influence of humor within organizations. Results: By observing humor and by being sensitive to its implications, rather than dismissing it simply as frivolity, managers can implement changes based on their interpretations of workplace humor. Negatively, humor can be an important device for protecting self-image and one’s social peers within an organization; where managers observe such socialization, they can move to improve staff relations. Spontaneous humor is also a useful training device, for evaluating how well new ideas have been communicated. Humor then can be a spur to initiative and to spontaneous responses. Where a manager wants to engage in pleasantries with employees then, it seems that industrially democratic humor is an important component of such interaction. Humor can be an important factor in industrial democracy and increased productivity. Conclusion: Humor can be an important device for building a tram spirit and for forming a cohesive unit, unanimously concerned with its own survival and profitability.

    Full Text Available To evaluate the postoperative changes in blebs and levels of aqueous monocyte chemotactic protein-1 (MCP-1 after trabeculectomy vs. Ex-PRESS tube shunt surgery.Rabbits were subjected to trabeculectomy or Ex-PRESS tube shunt surgery and observed for up to 3 months. Intraocular pressure (IOP was measured using a rebound tonometer. The MCP-1 level was measured by enzyme-linked immunosorbent assay (ELISA. Bleb morphology was evaluated using photos and anterior-segment optical coherence tomography (OCT.There were no differences in bleb appearance or IOP at any time between the groups. Bleb wall density in the anterior-segment OCT image was significantly lower 1 week after surgery in the Ex-PRESS group than the trabeculectomy group. The MCP-1 level in control eyes was 304.1 ± 45.2 pg/mL. In the trabeculectomy group, the mean aqueous MCP-1 level was 1444.9, 1914.3, 1899.8, 516.4, 398.3, 427.3, 609.5, 1612.7, 386.2, and 167.9 pg/mL at 3, 6, and 12 h, and 1, 2, 5, 7, 14, 30, and 90 days after surgery, respectively. In the Ex-PRESS group, the corresponding values were 1744.0, 1372.0, 932.5, 711.7, 396.1, 487.3, 799.5, 1327.9, 293.6, and 184.0 pg/mL. There were no significant differences in the aqueous MCP-1 level between the groups at any time point.The postoperative changes were similar in the Ex-PRESS and trabeculectomy groups, except for bleb wall density in the anterior-segment OCT image. The postoperative aqueous MCP-1 level had bimodal peaks in both groups.

    The effects of dietary administration of peppermint (Mentha piperita L.) on Caspian brown trout fish (Salmo trutta caspius) were studied. Fish were divided into 4 groups before being fed diets supplemented with 0% (control), 1%, 2% and 3% of peppermint extracts for 8 weeks. Dose-dependent increases in growth, immune (both in skin mucus and blood serum) and hematological parameters (number of white cells, hematocrit and hemoglobin content), as well as in amylase activity and in the number of lactic acid bacteria on intestine were recorded in fish fed supplemented diets compared to control fish. However, the dietary peppermint supplements have different effects on the number of blood leucocytes depending on the leukocyte cell type. While no significant differences were observed in the number of blood monocytes and eosinophils, the number of lymphocytes was decreased, respectively, on fish fed peppermint enriched diets, respect to the values found in control fish. Furthermore, dietary peppermint supplements have no significant effect on blood biochemical parameters, enzymatic activities of liver determined in serum and total viable aerobic bacterial count on intestine of Caspian brown trout. Present results support that dietary administration of peppermint promotes growth performance and increases the main humoral immune parameters (both at mucosal and systemic level) and the number of the endogenous lactic acid bacteria of Caspian brown trout. This study underlying several positive effects of dietary administration of peppermint to farmed fish. PMID:26455650

  3. That’s Not Funny! – But It Should Be: Effects of Humorous Emotion Regulation on Emotional Experience and Memory

    2015-08-01

    Full Text Available Previous research has shown that humorous reappraisal can reduce elicited negative emotions, suggesting that humor may be a functional strategy to cope with emotionally negative situations. However, the effect of humorous reappraisal on later memory about the emotion-eliciting situation is currently unknown, although this is crucial for more adaptive responding in future situations. To address this issue, we examined the effects of humorous reappraisal on both emotional experience and memory, compared to non-humorous rational reappraisal and a non-reappraisal control condition. Replicating previous findings, humorous reappraisal reduced evoked negative valence and arousal levels very effectively, and the down-regulation of experienced negative emotions was even more pronounced after humorous compared to rational reappraisal. Regarding later memory for emotion-eliciting stimuli, both humorous and rational reappraisal reduced free recall, but recognition memory was unaffected, with memory strength being stronger after humorous than after rational reappraisal. These results indicate that humor seems to be indeed an optimal strategy to cope with negative situations because humor can help us to feel better when confronted with negative stimuli, but still allows us to retrieve stimulus information later when afforded to do so by the presence of appropriate contextual features.

    The association between relational aggression and popularity during early adolescence is well established. Yet, little is known about why, exactly, relationally aggressive young adolescents are able to achieve and maintain high popular status among peers. The present study investigated the mediating role of humor in the association between relational aggression and popularity during early adolescence. Also considered was whether the association between relational aggression and humor varies according to adolescents' gender and their friends' levels of relational aggression. Participants were 265 sixth-grade students (48% female; 41% racial/ethnic minority; M age = 12.04 years) who completed peer nomination and friendship measures in their classrooms at two time points (Wave 1: February; Wave 2: May). The results indicated that Wave 1 relational aggression was related to Wave 1 and 2 popularity indirectly through Wave 1 humor, after accounting for the effects of Wave 1 physical aggression, ethnicity, and gender. Additional analyses showed that relational aggression and humor were related significantly only for boys and for young adolescents with highly relationally aggressive friends. The results support the need for further research on humor and aggression during early adolescence and other mechanisms by which relationally aggressive youth achieve high popular status.

    Present concepts of disposal of low-level aqueous wastes (LLAW) that contain much of the fission-product tritium from light water reactors involve dispersal to the atmosphere or to surface streams at fuel reprocessing plants. These concepts have been challenged in recent years. Deep-well injection of low-level aqueous wastes, an alternative to biospheric dispersal, is the subject of this presentation. Many factors must be considered in assessing its feasibility, including technology, costs, environmental impact, legal and regulatory constraints, and siting. Examination of these factors indicates that the technology of deep-well injection, extensively developed for other industrial wastes, would require little innovation before application to low-level aqueous wastes. Costs would be low, of the order of magnitude of 10/sup -4/ mill/kWh. The environmental impact of normal deep-well disposal would be small, compared with dispersal to the atmosphere or to surface streams; abnormal operation would not be expected to produce catastrophic results. Geologically suitable sites are abundant in the U.S., but a well would best be co-located with the fuel-reprocessing plant where the LLAW is produced. Legal and regulatory constraints now being developed will be the most important determinants of the feasibility of applying the method.

    Full Text Available A corpus of 313 freshman college essays was analyzed in order to better understand the forms and functions of humor in academic writing. Human ratings of humor and wordplay were statistically aggregated using Factor Analysis to provide an overall Humor component score for each essay in the corpus. In addition, the essays were also scored for overall writing quality by human raters, which correlated (r = .195 with the humor component score. Correlations between the humor component scores and linguistic features were examined. To investigate the potential for linguistic features to predict the Humor component scores, regression analysis identified four linguistic indices that accounted for approximately 17.5% of the variance in humor scores. These indices were related to text descriptiveness (i.e., more adjective and adverb use, lower cohesion (i.e., less paragraph-to-paragraph similarity, and lexical sophistication (lower word frequency. The findings suggest that humor can be partially predicted by linguistic features in the text. Furthermore, there was a small but significant correlation between the humor and essay quality scores, suggesting a positive relation between humor and writing quality.Keywords: humor, academic writing, text analysis, essay score, human rating

    Research has shown that a factor in a victim’s forgiveness of an offender is the victim’s ability to make more positive, or at least less negative, attributions of the offender’s behavior and that perspective-taking can be a factor in facilitating that process. Self-enhancing humor has been found to be positively correlated with perspective-taking empathy and aggressive humor found to be negatively correlated with perspective-taking empathy. Therefore it was predicted that self-enhancing humor would be positively correlated with forgiveness and aggressive humor negatively correlated with forgiveness. The Humor Styles Questionnaire, the Absence of Negative and Presence of Positive subscales of the Forgiveness Scale, and the Forgiveness Likelihood Scale were administered to 112 college undergraduates. Self-enhancing humor was significantly and positively correlated with all of the forgiveness measures, aggressive humor and self-defeating humor were significantly and negatively correlated with some of the forgiveness measures and affiliative humor was not significantly correlated with any of the forgiveness measures. The results were interpreted in terms of previous findings for humor styles, perspective-taking empathy, depression, self-esteem and anxiety. Future research involving the extent to which other personality variables, such as perspective-taking empathy, mediate the relationship between self-enhancing humor and forgiveness was suggested.

    Basic personality traits (e.g., extraversion) have been found to be associated with the humor styles that individuals employ. In the present study, we were interested in determining whether pathological personality traits were also associated with humor styles. We examined the associations between the pathological personality traits captured by the Personality Inventory for the DSM-5 (PID-5) and humor styles in a sample of college students (N = 594). Negative affectivity and detachment were negatively associated with the affiliative and self-enhancing humor styles. Antagonism was positively associated with the aggressive humor style but negatively associated with the affiliative humor style. Disinhibition was positively associated with the aggressive humor style, whereas disinhibition and psychoticism were both positively associated with the self-defeating humor style. Discussion focuses on the implications of these findings and how they can expand our understanding of the connections between the darker aspects of personality and humor. PMID:27547254

    Full Text Available Abstract Background Immunity to food antigens (gliadin, cow's milk proteins is in the centre of the attention of modern medicine focused on the prevention of diseases, prevention which is based on the use of appropriate restriction diet. Detection of the enhanced levels of the immune reactions to antigen(s present in food is from this point of view of great importance because there are reports that some of health disturbances, like celiac disease (CD and some premalignant conditions, like monoclonal gammopathy of undetermined significance (MGUS, were vanished after the appropriate restriction diets. It is well known that gliadin is toxic to small bowel mucosa of relatively small population of genetically predisposed individuals, who under this toxic action develop celiac disease (CD. As the quantity of immunogenic gliadin could vary between different wheat species, the first aim of this work was to determine the percentage of immunogenic gliadin in ten bread wheat cultivars and in three commercially grown durum wheat cultivars. The second part of the study was initiated by results of previous publication, reporting that sera of some of multiple myeloma (MM patients showed the presence of elevated levels of anti-gliadin IgA, without the enhanced levels of anti-gliadin IgG antibodies, determined with commercial ELISA test. It was designed to assess is it possible to reveal is there any hidden, especially anti-gliadin IgG immunoreactivity, in serum of mentioned group of patients. For this purpose we tested MM patients sera, as well as celiac disease (CD patients sera for the immunoreaction with the native gliadin isolated from wheat species used for bread and pasta making in corresponding geographic region. Results Gliadin was isolated from wheat flour by two step 60% ehanolic extraction. Its content was determined by commercial R5 Mendez Elisa using PWG gliadin as the standard. Results obtained showed that immunogenic gliadin content varies

    The present study examined the relationships between four personality traits, humor styles, and happiness. Replicating previous research, happiness was positively correlated with four personality traits: extraversion, locus of control, self-esteem, and optimism. Further, happiness positively related to self-enhancing and affiliative humor styles; it related negatively to self-defeating and aggressive humor styles. Thus, happy people habitually engage in positive uses of humor and avoid engaging in negative uses of humor in daily life. We also found support for our hypothesis. People high in extraversion, locus of control, self-esteem, and optimism are happier because they engage in positive humor in daily life. PMID:27547251

    Carbon materials have been widely used to form air cathodes for non-aqueous sodium-oxygen (Nasbnd O2) batteries due to their large specific surface area, high conductivity and low cost. However, the effect of carbon structures at the atomic level remains poorly understood. In this work, a first-principles study is conducted to investigate how representative carbon structures, including graphite (0001) surface, point defects and fractured edge, influence the discharge and charge processes of non-aqueous Nasbnd O2 batteries. It is found that the single vacancy (SV) defect has the largest adsorption energy (5.81 eV) to NaO2 molecule among the structures studied, even larger than that of the NaO2 molecule on NaO2 crystal (2.81 eV). Such high adsorption energy is attributed to two factors: the dangling atoms in SV defects decrease the distance from NaO2 molecules, and the attachment through oxygen atoms increases the electrons transfer. The findings suggest that SV defects can act as the nucleation sites for NaO2 in the discharge process, and increasing the number of SV defects can facilitate the uniform formation of small-sized particles. The uniformly distributed discharge products lower the possibility for pore clogging, leading to an increased discharge capacity and improved cyclability for non-aqueous Nasbnd O2 batteries.

    Material and Methods: Two hundred three medical students (107 males, 96 females were included this study. Self-esteem was measured with the Rosenberg Self Esteem Scale and humor style was measured with Humor Styles Questionnaire. Results: The rate of students who have mild or high self-esteem levels was 89.7%. In Humor Styles Questionnaire, the average scores of affiliative and self-enhancing humor were significantly higher than the average scores of aggressive and self-defeating humor. Male students were using humor, especially aggressive and self-defeating humor styles more commonly than female students. A positive correlation was found between self-esteem and affiliative and self-enhancing humor styles. Conclusion: The present study revealed a positive correlation between self-esteem and positive humor styles. There is a need to develop educational models that would bolster self-esteem and positive humor in medical students. [Cukurova Med J 2015; 40(4.000: 782-793

    © 2014 by Walter de Gruyter Berlin/Munich/Boston. Irony is often related to humor, both in spoken and written language. One possibility is that humor arises once people reconcile the incongruity between what speakers say and imply when using irony. Humor automatically emerges in these cases given the release of tension following a momentary sense of disparity. Our claim is that this proposal does not capture many of the dynamic complexities in real-world ironic discourse. We describe psycholo...

    Cognitive distortions are negative biases in thinking that are theorized to represent vulnerability factors for depression and dysphoria. Despite the emphasis placed on cognitive distortions in the context of cognitive behavioural theory and practice, a paucity of research has examined the mechanisms through which they impact depressive symptomatology. Both adaptive and maladaptive styles of humor represent coping strategies that may mediate the relation between cognitive distortions and depressive symptoms. The current study examined the correlations between the frequency and impact of cognitive distortions across both social and achievement-related contexts and types of humor. Cognitive distortions were associated with reduced use of adaptive Affiliative and Self-Enhancing humor styles and increased use of maladaptive Aggressive and Self-Defeating humor. Reduced use of Self-Enhancing humor mediated the relationship between most types of cognitive distortions and depressed mood, indicating that distorted negative thinking may interfere with an individual's ability to adopt a humorous and cheerful outlook on life (i.e., use Self-Enhancing humor) as a way of regulating emotions and coping with stress, thereby resulting in elevated depressive symptoms. Similarly, Self-Defeating humor mediated the association of the social impact of cognitive distortions with depression, such that this humor style may be used as a coping strategy for dealing with distorted thinking that ultimately backfires and results in increased dysphoria.

Similarly, Self-Defeating humor mediated the association of the social impact of cognitive distortions with depression, such that this humor style may be used as a coping strategy for dealing with distorted thinking that ultimately backfires and results in increased dysphoria.

  9. Multi-analyte approach for the determination of ng L-1 levels of steroid hormones in unidentified aqueous samples

    International Nuclear Information System (INIS)

    Since the 1970s, many analytical methods for the detection of illegal growth promoters, such as thyreostats, anabolics, β-agonists and corticosteroids have been developed for a wide range of matrices of animal origin, including meat, fat, organ tissue, urine and faeces. The aim of this study was to develop an analytical method for the determination of ng L-1 levels of estrogens, gestagens, androgens (EGAs) and corticosteroids in aqueous preparations (i.e. drinking water, drinking water supplements), commercially available on the 'black' market. For this, extraction was performed with Bakerbond C18 speedisk, a technique commonly used in environmental analysis. After fractionation, four fractions were collected using a methanol:water gradient program. Gas chromatography coupled to electron impact multiple mass spectrometry (GC-EI-MS2) screening for the EGAs was carried out on the derivatized extracts. For the detection of corticosteroids, gas chromatography coupled to negative chemical ionization mass spectrometry (GC-NCI-MS) was used after oxidation of the extracts. Confirmation was done by liquid chromatography coupled to electrospray ionization multiple mass spectrometry (LC-ESI-MS2). The combined use of GC and LC coupled to MS enabled the identification and quantification of anabolics and corticosteroids at the low ng L-1 level. This study demonstrated the occurrence of both androgens and corticosteroids in different commercial aqueous samples

  13. Using Psychophysiological Measures to Examine the Temporal Profile of Verbal Humor Elicitation.

    Chris M Fiacconi

    Full Text Available Despite its pervasiveness in popular culture, there remains much to be learned about the psychological and physiological processes that underlie our experience of humor. In the present study, we examined the temporal profile of verbal humor elicitation using psychophysiological measures of heart rate (HR and facial electromyography (EMG. Consistent with recent prior research on cardiovascular changes to perceived humor, we found that HR acceleration was greater for jokes relative to non-jokes, and was positively related to the level of perceived humor elicited by these jokes. In addition, activity recorded from the zygomaticus major muscle that controls smiling was found to be greater for jokes relative to non-jokes. To link these physiological changes to the psychological processes that govern humor comprehension, we took the initial inflection point of the zygomatic EMG response as a marker for the onset of humor comprehension, and used this marker to probe the pattern of cardiovascular activity at this time-point. We estimated the onset of the humor response to occur during the initial HR deceleration phase, and found that jokes relative to non-jokes elicited a decreased HR response at this time-point. This result questions the previously forwarded notion that the psychological "moment of insight" that signals the start of the humor response is always associated with heightened cardiovascular activity. This discrepancy is discussed in relation to possible differences in the cognitive processes required to comprehend different forms of humor. At a broader level, our results also demonstrate the advantages of combining different psychophysiological measures to examine psychological phenomena, and illustrate how one such measure can constrain the interpretation of others.

    This paper is based upon the writings of William James in the late 19th century, and Alfred Adler and Sigmund Freud in the 20th, enriched by the contributions of later personality and role theorists. The self is defined as the unique organization of each person; a style is the self in action. Different life styles and their components are expressed in different situations. I posit that humor and positive thinking, combined with meaning and purpose, are vital components of all constructive life styles. The knowledge of life styles cuts through diagnostic labels to reveal our universal humanity. It can be fruitfully applied to patients and nonpatients alike and, I found, for the self-understanding of therapist. The clinical application of life styles is illustrated through numerous vignettes. PMID:11641883

  17. A Fiber-Optic Sensor Using an Aqueous Solution of Sodium Chloride to Measure Temperature and Water Level Simultaneously

    2014-10-01

    Full Text Available A fiber-optic sensor system using a multiplexed array of sensing probes based on an aqueous solution of sodium chloride (NaCl solution and an optical time-domain reflectometer (OTDR for simultaneous measurement of temperature and water level is proposed. By changing the temperature, the refractive index of the NaCl solution is varied and Fresnel reflection arising at the interface between the distal end of optical fiber and the NaCl solution is then also changed. We measured the modified optical power of the light reflected from the sensing probe using a portable OTDR device and also obtained the relationship between the temperature of water and the optical power. In this study, the water level was simply determined by measuring the signal difference of the optical power due to the temperature difference of individual sensing probes placed inside and outside of the water. In conclusion, we demonstrate that the temperature and water level can be obtained simultaneously by measuring optical powers of light reflected from sensing probes based on the NaCl solution. It is anticipated that the proposed fiber-optic sensor system makes it possible to remotely monitor the real-time change of temperature and water level of the spent fuel pool during a loss of power accident.

    Full Text Available Ética del humor es una obra original, abundantemente documentada, de contenido científico y filosófico, que aborda un problema de gran importancia en los actuales estudios de éticas aplicadas. La ética del humor es una nueva ética aplicada que pretende comprender el fenómeno del humor a la luz de sus implicaciones éticas. Como señala el autor, Juan Carlos Siurana, reputado experto en el ámbito de la filosofía práctica, el interés por el humor es un interés por la ética. En la obra no presenta una nueva teoría filosófica del humor –las cuales se han venido sucediendo, al menos, desde los Diálogos de Platón–, sino una nueva teoría ética, que toma al humor como objeto principal de análisis. Por tanto, la finalidad es realizar una aportación dentro del ámbito de la ética. Para ello se nutre de distintos estudios psicológicos, biológicos, fisiológicos y neurológicos sobre el humor, así como de clásicas obras de filosofía que han abordado esta cuestión.

  19. Last Laughs: Gallows Humor and Medical Education.

    2015-12-01

    This paper argues that "backstage" gallows humor among clinical mentors not only affects medical students' perceptions of what it means to be a doctor but is also symptomatic and indicative of a much larger problem in medicine-namely, the failure to attend fully to the complexity and profundity of the lived experiences of illness, suffering, and death. Reorienting the discourse surrounding gallows humor away from whether or in what context it is acceptable and toward the reasons why doctors feel the need to use such humor in the first place addresses this issue in a more illuminating way.

    Numerous studies point to the reactive uptake of gaseous low molecular weight carbonyls onto atmospheric waters (clouds/fog droplets and wet aerosols) as an important SOA formation route not yet included in current models. However, the evaluation of these processes is challenging because water provides a medium for a complex array of reactions to take place such as self-oligomerization, aldol condensation and Maillard-type browning reactions in the presence of ammonium salts. In addition to adding to SOA mass, aqueous chemistry products have been shown to include light absorbing, surface-active and high molecular weight oligomeric species, and can therefore affect climatically relevant aerosol properties such as light absorption and hygroscopicity. Glyoxal (GLY) and methylglyoxal (MGLY) are the gaseous carbonyls that have perhaps received the most attention to date owing to their ubiquity, abundance and reactivity in water, with the majority of studies focussing on bulk physical properties. However, very little is known at the molecular level, in particular for MGLY, and the relative potential of these species as aqueous SOA precursors in ambient air is still unclear. We have conducted experiments with both laboratory solutions and chamber-generated particles to simulate the aqueous processing of GLY and MGLY with ammonium sulphate (AS) under typical atmospheric conditions and investigated their respective aging products. Both high performance liquid chromatography coupled with UV-Vis detection and ion trap mass spectrometry (HPLC-DAD-MSn) and high resolution mass spectrometry (FTICRMS) have been used for molecular identification purposes. Comprehensive gas chromatography with nitrogen chemiluminescence detection (GCxGC-NCD) has been applied for the first time to these systems, revealing a surprisingly high number of nitrogen-containing organics (ONs), with a large extent of polarities. GCxGC-NCD proved to be a valuable tool to determine overall amount and rates of

  7. Removal of trace level aqueous mercury by adsorption and photocatalysis on silica-titania composites

    International Nuclear Information System (INIS)

    Silica-titania composites (STCs) were applied to trace level mercury solutions (100 μg/L Hg) to determine the degree of mercury removal that could be accomplished via adsorption and photocatalysis. STCs are a porous, high surface area silica substrate (>200 m2/g), manufactured using sol-gel methodology, impregnated with TiO2 nanoparticles. The performance of this material along with its precursors, silica and Degussa P25 TiO2 were compared. Under adsorption alone (no UV illumination), STCs were able to achieve approximately 90% removal of mercury, which is comparable to that of Degussa P25. Silica without TiO2 performed poorly in comparison and was minimally affected by UV illumination. Contrary to expectations, the performance of Degussa P25 was not largely changed by UV irradiation and the STC was detrimentally affected under the same conditions. It was concluded that elemental mercury was formed under UV irradiation with or without the presence of TiO2 due to photochemical reactions, decreasing the mercury removal by STC. Additionally, the primary particle size of the STC was reduced to increase mass transfer. The result was improved Hg removal under adsorption and photocatalysis conditions. Improved adsorption kinetics were also achieved by altering the STC pore size and TiO2 loading.

    Full Text Available In this study, attempt is made to establish changes in serum and liver lipoprotein cholesterols accompanying Plasmodium berghei malarial infection in mice treated with aqueous extract of Ganoderma lucidum at 100, 250, and 500 mg/kg body weight in comparison with 15 mg/kg chloroquine (CQ. Significant increases in all the lipoprotein fractions were observed in infected untreated mice compared with normal control mice. Treatment with 100 and 250 mg/kg G. lucidum extract produced significant reduction in serum total cholesterol (TC and low-density cholesterol (LDL-C contents compared with 500 mg/kg G. lucidum and CQ. Treatment with CQ, however, produced significant reduction in hepatic TC and LDL-C compared with the extract. A dose-dependent significant increase in serum high-density lipoprotein cholesterol (HDL-C was observed in the G. lucidum treated mice compared with normal control but significantly lower compared with CQ-treated mice. Liver HDL-C level was significantly higher in CQ-treated mice compared with normal control and significantly lower compared with G. lucidum-treated and infected untreated mice. A dose-dependent effect of the extract was observed in both serum and liver very-low density lipoprotein cholesterol (VLDL-C. The implication of these results is discussed with respect to the parasite survival and proliferation in the serum and liver.

  11. Identity and Stereotypes: Humor Manifestations

    Directory of Open Access Journals (Sweden)

    Rita Repšienė

    2012-04-01

    Full Text Available The traditional understanding of humor as being tolerant, full of non-aggressive life curiosities, funny situations, mocking national or human vices, and related to an optimistic and contemplative attitude towards reality, has changed its main supportive points: the optimistic view of reality has been altered into a pessimistic and destructive one, forbearing ridicule has turned into severe offence, strangeness into stupidity, funny situations into futile misunderstanding. Everything is regarded as a dramatic possibility to survive or an endless situational tragedy where the most strict evaluation criteria, censorship, and dogmatism are empowered, meaning that, in the current times of widely propagated tolerance and overwhelming comprehension, it is extremely dangerous to offend somebody with an innocent joke or light mockery, to evoke an urge to contradict or negate when ideological aspirations are beyond “decency” limits. One of the most advocated rules in the Lithuanian press is: “Joke carefully with foreign nationals” from an interview with Barry Tomelin, London “International house” consultant and teaching director, the author of the book “World’s Business Cultures: And How to Unlock Them” (with Michael Nicks. Identity is to be saved and nourished as the highest sanctity but its formation, meaningfulness and spread are not always attuned to the official approach.Our life is full of stereotypes and our neighboring countries are not to be excluded – we have a preconceived notion of them.

    2010-01-01

    Summary Dendritic cells (DCs) orchestrate the innate and adaptive immune systems to induce tolerance and immunity. DC plasticity and subsets are prominent determinants in the regulation of immune responses. Our recent studies suggest that humoral and cellular immunity is regulated by different myeloid DC subsets with distinct intrinsic properties in humans. While antibody response is preferentially mediated by CD14+ dermal DCs, cytotoxic T cell response is preferentially mediated by Langerhans cells (LCs). Thus, mechanisms whereby DCs induce humoral and cellular immunity appear to be fundamentally distinct. In this review, we will focus on the role of DCs in the development of humoral immunity. We will also discuss the mechanisms whereby DCs induce CD4+ T cells associated with the help of B cell response, including T follicular helper (Tfh) cells, and why human LCs lack this ability.

  14. The effect of varying levels of surfactant on the reactive uptake of N2O5 to aqueous aerosol

    Directory of Open Access Journals (Sweden)

    J. A. Thornton

    2006-01-01

    Full Text Available Recent observations have detected surface active organics in atmospheric aerosols. We have studied the reaction of N2O5 on aqueous natural seawater and NaCl aerosol as a function of sodium dodecyl sulfate (SDS concentration to test the effect of varying levels of surfactant on gas-aerosol reaction rates. SDS was chosen as a proxy for naturally occurring long chain monocarboxylic acid molecules, such as palmitic or stearic acid, because of its solubility in water and well-characterized surface properties. Experiments were performed using a newly constructed aerosol flow tube coupled to a chemical ionization mass spectrometer for monitoring the gas phase, and a differential mobility analyzer/condensation particle counter for determining aerosol surface area. We find that the presence of ~3.5 wt% SDS in the aerosol, which corresponds to a monolayer surface coverage of ~2×1014 molecules cm−2, suppresses the N2O5 reaction probability, γN2O5, by approximately a factor of ten, independent of relative humidity. Consistent with this observation is a similar reduction in the rate of ClNO2 product generation measured simultaneously. However, the product yield remains nearly constant under all conditions. The degree of suppression is strongly dependent on SDS content in the aerosol, with no discernable effect at 0.1 wt% SDS, but significant suppression at what we predict to be submonolayer coverages with 0.3–0.6 wt% SDS on NaCl and natural seawater aerosols, respectively.

    “Dialogue”, in Bakhtin’s thought, is a term which has a methodological nature. This term shows a method for facing cases which are not hegemonic. Dialogue, therefore, is in opposition to the hegemony of monophonic forces. The origins of the dialogical aspects of humor, laugh and carnival are in very character. In this article, we want to investigate the bases that make the dialogical carnival and form the humorous elements. In the first section, we illustrate the subversion of the superior vo...

  19. Investigations of actinides in the context of final disposal of high-level radioactive waste - trivalent actinides in aqueous solution

    International Nuclear Information System (INIS)

    This contribution presents a small piece of research work at KIT-INE dealing with the speciation of redox sensitive trivalent actinides like Pu(III), Np(III), and U(III) in aqueous solution. The redox preparation, stabilization, and speciation of trivalent actinide in aqueous systems are discussed here. The reductants investigated were rongalite, HYA (hydroxylamine hydrochloride), and AHA (acetohydroxamic acid). The time dependence of An(III) stability at different pH values was investigated. The An(III) species in aqueous solution have been characterized by UV-Vis and XANES spectroscopy. A broader overview of the work at KIT-INE is given in the oral presentation at the NUCAR2013 conference. (author)

    The results of studying in dynamics of the humoral immunity indices were adduced in experimental cranio-cerebral truma (CCT) in conjunction with diabetes mellitus (DM). Peculiarities of the immune answer while the period of an acute reaction on trauma and early signs of posttraumatic period have been characterized by reduction of content in the main classes of immunoglobulins IgA, IgM, IgG and enhancement of the circulating immune complexes (CIC) concentration. Experimental DM was accompanied by raising of functional activity of humoral immunity in accordance with immunoglobulins level and CIC. The specificity of changes in humoral immunity in conditions of CCT on the DM background consisted of more profound lowering of the immunoglobulins level and rapid enhancement of the CIC content.

    Not all humor is the same, yet little is known about the appeal of specific humor styles in romantic initiation. The current experimental study addresses this gap by investigating how romantic motives (short-term or long-term) affect individuals’ anticipated use of, and response to, positive humor and negative humor. Heterosexual participants (n = 224) imagined the pursuit of either a desired short-term or long-term relationship, indicated the extent to which they would produce positive and negative humor, and reported how their own interest would change in response to the imaginary target’s use of positive or negative humor. Results revealed that individuals are strategic in their humor production as a function of relational motives. Individuals produced positive humor in both contexts but limited their use of negative humor when pursuing a long-term relationship. The target’s positive humor increased individuals’ attraction, especially women’s, and although negative humor boosted attraction, it did not boost attraction more for short-term than long-term relationships. Findings extend a trait-indicator model of humor and their implications are discussed in light of other theoretical perspectives. PMID:27547256

    Full Text Available The attempt to establish a coherence between the cognitive description of language and thought and the neurobiological description of the human brain is often limited by lacking knowledge concerning the interplay between cognition and emotion – both necessary elements in understanding the way the brain works. Verbal humor is a convenient research object in this regard, as it consists (primarily in cognitive mechanisms, eliciting an emotional response – laughter. In this article, a review of the history of humor research is compared to a selection of studies (lesion-studies, ERP and fMRI on the relationship between humor, language and the brain, as an attempt to show how a broadly based theory of humor can help us to understand the relationship between cognition and emotion.

    Full Text Available Este ensayo analiza la prosa panfletaria de Juan Montalvo desde el punto de vista del humor. Montalvo, además de dedicar muchas páginas a disertar sobre la risa, buscó con frecuencia insertar efectos humorísticos en su estilo, encaminados a ridiculizar a sus enemigos políticos. ¿Hasta qué punto un autor eminentemente moralista, un libelista cáustico como Montalvo, que echa mano del insulto, la burla y el sarcasmo, puede considerarse un humorista? Para comprender esta ambigüedad entre un Montalvo solemne y otro burlón, entre un Montalvo austero y otro irónico se analizan aquí ciertos recursos literarios que utiliza este autor y con los que provoca efectos que lindan con lo humorístico.This work analyses Juan Montalvo's pamphlet prose from a humorous perspective. To what extent can an eminently caustic moralist author as Montalvo, who uses insult, mockery and sarcasm, be considered a humorist? In order to understand this ambiguity between a solemn Montalvo and a Mocking one, between an austere and an ironic one, certain resources used by the author are analysed, resources that border on humour.

In the first section, we illustrate the subversion of the superior voice as a semantic and formal structural method in Mathnavi. In the second section, the reflection of this method in formation of humor in the stories of Mathnavi has been investigated. In these stories, presence of the superior voice in the public space and its dialogue with the suppressed voices makes a space steeped in the elements of carnival and laugh. It can be said that the humors in Mathnavi are not the techniques for embellishing the text but the affects of the transcendental method of Mathnavi for interpreting the world.

  16. Anomalous hypothalamic responses to humor in cataplexy.

    Directory of Open Access Journals (Sweden)

    Allan L Reiss

    Full Text Available BACKGROUND: Cataplexy is observed in a subset of patients with narcolepsy and affects approximately 1 in 2,000 persons. Cataplexy is most often triggered by strong emotions such as laughter, which can result in transient, yet debilitating, muscle atonia. The objective of this study was to examine the neural systems underlying humor processing in individuals with cataplexy. METHODOLOGY/PRINCIPAL FINDINGS: While undergoing functional Magnetic Resonance Imaging (fMRI, we showed ten narcolepsy-cataplexy patients and ten healthy controls humorous cartoons. In addition, we examined the brain activity of one subject while in a full-blown cataplectic attack. Behavioral results showed that participants with cataplexy rated significantly fewer humorous cartoons as funny compared to controls. Concurrent fMRI showed that patients, when compared to controls and in the absence of overt cataplexy symptoms, showed pronounced activity in the emotional network including the ventral striatum and hypothalamus while viewing humorous versus non-humorous cartoons. Increased activity was also observed in the right inferior frontal gyri--a core component of the inhibitory circuitry. In comparison, the one subject who experienced a cataplectic attack showed dramatic reductions in hypothalamic activity. CONCLUSIONS: These findings suggest an overdrive of the emotional circuitry and possible compensatory suppression by cortical inhibitory regions in cataplexy. Moreover, during cataplectic attacks, the hypothalamus is characterized by a marked decrease in activity similar to that observed during sleep. One possible explanation for these findings is an initial overdrive and compensatory shutdown of the hypothalamus resulting in full cataplectic symptoms.

  17. No Occasion for Pleasure: The Self-Worth Contingency of a Setback and Coping With Humor

    Directory of Open Access Journals (Sweden)

    Fay Caroline Mary Geisler

    2014-08-01

    Full Text Available Whether or not one uses humor to cope with a setback may depend on the idiosyncratic relation of the setback to feeling of self-worth. All people pursue the higher order goal of self-validation, but people differ in what domains of life their self-worth is contingent upon and to what extent. In this article based on an incongruity theory of humor we argue that the use of humor in coping with a highly self-worth-contingent setback may be impeded by two cognitive-motivational processes: goal-driven activation and goal shielding. From the outlined theory we derived the hypothesis that the more a domain is contingent upon self-worth, the less likely a person will be to use humor to deal with a setback in that domain. We tested this hypothesis in two studies employing two forms of self-report, i.e., ratings of reaction likelihood to setbacks described at an abstract domain level (Study 1, and ranking of reaction likelihood to concrete setbacks from different domains (Study 2. The hypothesis was affirmed in different domains of self-worth contingency controlling for the influence of habitual coping with humor, coping by disengagement, and global self-esteem.

    This study determined the effects of initial infestation of cowpea seeds (Ife brown variety) with different insect densities (0, 2, 4 and 6 pairs per 50 g seeds) ofCallosobruchus maculatus(F.) and evaluated the effects of aqueous leaf extract of Nicotiana tabacum L. onC. maculatus in the laboratory. It was observed that adult beetle population increased significantly (p<0.05) with increase in insect density. The increase in population of beetles and corresponding weight loss of the seeds in different levels of infestation showed that the cowpea variety was susceptible to beetle infestation, emergence and survival of progeny. Significantly more adults emerged on higher infestation compared to lower and no infestation. In Nigeria,Nicotiana tabacum L. is a locally available plant, with known insecticidal properties. The plant leaf extract was easily extracted with water and confirmed its effectiveness as a protective agent for stored cowpea seeds. Experiment was conducted to assess the effects of aqueous extracts of N. tabacumat 0, 0.1, 0.2 and 0.3 mL•50 g-1 cowpea seeds onC. maculatus. Data was recorded and showed varying levels of effectiveness againstC. maculatus. Result showed that seed appearance was dependent on levels of insect population, while N. tabacum aqueous extract exerted effects on survival ofC. maculatus. Aqueous leaf extract ofN. tabacum probably contained some insecticidal properties which might have significantly conferred beetle mortality and reduced beetle emergence leading to a decrease in seed weight loss.

  2. Differentiating what is humorous from what is not.

    Warren, Caleb; McGraw, A Peter

    2016-03-01

    After 2.5 millennia of philosophical deliberation and psychological experimentation, most scholars have concluded that humor arises from incongruity. We highlight 2 limitations of incongruity theories of humor. First, incongruity is not consistently defined. The literature describes incongruity in at least 4 ways: surprise, juxtaposition, atypicality, and a violation. Second, regardless of definition, incongruity alone does not adequately differentiate humorous from nonhumorous experiences. We suggest revising incongruity theory by proposing that humor arises from a benign violation: something that threatens a person's well-being, identity, or normative belief structure but that simultaneously seems okay. Six studies, which use entertainment, consumer products, and social interaction as stimuli, reveal that the benign violation hypothesis better differentiates humorous from nonhumorous experiences than common conceptualizations of incongruity. A benign violation conceptualization of humor improves accuracy by reducing the likelihood that joyous, amazing, and tragic situations are inaccurately predicted to be humorous.

    Serial changes of humor comprehension evoked by a well organized four-frame comic Manga were investigated by fMRI in each step of humor comprehension. The neural substrates underlying the amusing effects in response to funny and mixed order manga were compared. In accordance with the time course of the four frames, fMRI activations changed serially. Beginning with the second frame (development scene), activation of the temporo-parietal junction (TPJ) was observed, followed by activations in the temporal and frontal areas during viewing of the third frame (turn scene). For the fourth frame (punch line), strong increased activations were confirmed in the medial prefrontal cortex (MPFC) and cerebellum. Interestingly, distinguishable activation differences in the cerebellum between funny and non-funny conditions were also found for the fourth frame. These findings suggest that humor comprehension evokes activation that initiates in the TPJ and expands to the MPFC and cerebellum at the convergence level. PMID:25059843

One and half hours after administration of glucose (equivalent to 2 h after administration of plant extract or tolbutamide), the mean blood glucose level of the Ipomoea aquatica treated group was 47.5% lower than that of the control group treated with distilled water. The tolbutamide treated group showed a mean blood glucose level which was only 33.8% lower than that of the control group. However, statistical analysis indicated that the blood glucose levels of the Ipomoea aquatica treated group were not significantly different from that of the tolbutamide treated group. Our results show that the aqueous extract of Ipomoea aquatica is as effectve as tolbutamide in reducing the blood glucose levels of glucose-challenged Wistar rats. PMID:11746851

    Full Text Available Sam ShusterNewcastle University, Newcastle Upon Type, NE1 7RU, UKAbstract: The response to seeing a man riding a unicycle was reported to be consistently related to the viewer's sex and stage of physical development. To see if this observation was universal, observations of responses were collected from 23 male and 9 female unicyclists aged 15–69 years, with 2–40 years cycling experience across four continents. With two exceptions among men, the findings were the same as those originally reported: children showed interest and curiosity, young girls showed little interest, while adult women showed a kindly, concerned, praising response. By contrast, boys showed physical aggression, which became more verbal, merging in the later teens to the snide, aggressive, stereotyped humorous response shown by adult males, which became less frequent in elderly men. The universality of the response across different individuals, environments, and dates of observation suggests an endogenous mechanism, and the association with masculine development relates this to androgen. The theoretical consequences are discussed. It is concluded that humor develops from aggression in males and is evolutionarily related to sexual selection.Keywords: humor evolution, male aggressive behavior

    Humor has been recognized by nurse researchers and practitioners as a constructive therapeutic intervention and has shown positive psychological and physiological outcomes for patient care. Because cross-cultural research on humor is sparse, this preliminary study investigates how nursing faculty members approach teaching therapeutic humor in the classroom and clinical education in different countries. Through an investigation of classroom (didactic) education and clinical practicum with direct patient care, the study may elucidate the linkage between theory and practice as well as how nursing faculty members view therapeutic humor in general. Researching nursing faculty teaching practices and viewpoints of therapeutic humor may help reveal cultural differences in the use of humor in healthcare settings. This cross-cultural study included 40 nursing faculty at three nursing programs: two in the United States and one in Taiwan. A qualitative approach was used to perform content analysis on responses to the open-ended questionnaires. Research findings revealed cultural differences between faculties from the two countries. Taiwanese faculty members indicated that they teach more theory and concepts related to therapeutic humor in the classroom than do nursing faculty members from the United States. However, nursing faculty members in Taiwan reported that they observe and practice less therapeutic humor in clinical settings out of respect for the cultural value of "reverence of illness" operating within Taiwanese society. Therapeutic humor was family centered and interdependent on relationships, roles, duties, and responsibilities of family members. In contrast, the U.S. faculty members stated that they teach less theory and concepts related to therapeutic humor in the classroom but observe and practice humor more in clinical settings. United States faculty approached teaching therapeutic humor in the classroom on an informal basis because the subject was not part of

The first three models namely carbon clearance test, cyclophosphamide induced neutropenia and neutrophil adhesion test were used to study cell mediated immunity while the latter three models were used to see the effect on humoral immunity. Centchroman was administered orally at a dose of 5 mg/kg and levamisole (2.5 mg/kg/ p.o) was used as standard drug. Centchroman significantly increased the levels of serum immunoglobulins and also prevented the mortality induced by bovine Pasteurella multocida in mice. It also increased significantly the circulating antibody litre in indirect haemagglunation test. However, it did not show any significant effect on phagocytic index in carbon clearance assay and nor did influence the adhesion of neutrophils in the neutrophil adhesion test. Centchroman was also not effective in preventing the cyclophosphamde induced neutropenia. Hence, it was concluded that centchroman increases humoral immunity with no significant effect on cell mediated immunity. PMID:18476393

  13. Investigations of actinides in the context of final disposal of high-level radioactive waste. Trivalent actinides in aqueous solution

    International Nuclear Information System (INIS)

    The speciation of redox sensitive trivalent actinides Pu(III), Np(III), and U(III) has been studied in aqueous solution. The redox preparation, stabilization, and speciation of these trivalent actinides in aqueous systems are discussed here. The reductants investigated were rongalite, hydroxylamine hydrochloride, and acetohydroxamic acid and the An(III) species have been characterized by UV-Vis and XANES spectroscopy. The results show that the effectiveness of stabilization decreases generally in the order Pu(III) > Np(III) > U(III) and that the effectiveness of each reducing agent depends on the experimental conditions. More than 80 % of Pu(III) aquo species have been stabilized up to pH 5.5, whereas the Np(III) aquo ion could be stabilized in a pH range 0-2.5, and U(III) aquo ion is sufficiently stable at pH 1.0 and below over time periods suitable for experiments. However, this study gives a basis for the characterisation of the trivalent lighter actinides involved in complexation, sorption, and solid formation reactions in the future. (author)

    Full Text Available The purpose of this study was to examine the role of humor style and motor skills in vulnerability to bullying. 729 adults responded to the Humor Style Questionnaire (HSQ and items retrospectively addressing their motor skills and bullying experiences during childhood. Consistent with recent research, poorer motor skills were associated with a greater extent of having been bullied. An association between stronger motor skills and affiliative humor was found, lending support to a shared biological basis theory underlying social and motor competency processes. Most importantly, being bullied was associated with higher self-defeating humor and lower affiliative humor. This supports earlier theoretical work by Klein and Kuiper (2006 and highlights the role that humor styles play in social interactions that can promote positive peer acceptance and wellbeing.

    Public stigma is a barrier for people with mental illness. Humor may have the potential to decrease stigmatizing attitudes in the context of disclosure. Participants completed measures on stigmatizing attitudes and humor style and were then randomized to one of three conditions (self-disclosure comedy sketch, the same comedy sketch with no disclosure, and a control comedy sketch). After reviewing the comedy sketch, the participants repeated the attitude measures and provided perceptions of the comic. Humor styles and perceptions significantly interacted with condition to reduce stigma. Perceptions of the self-disclosed comic were associated with reduced stigma. People exhibiting affiliative humor style (i.e., they enjoy making others laugh) were shown to have significantly greater stigma changes in the disclosed condition compared with the nondisclosed and control conditions. Affiliative humor endorsers also interacted with the nondisclosed condition, suggesting that mental health comedy might generally reduce stigma in people who use humor to improve relationships.

    Matcha is a kind of powdered green tea produced by grinding with a stone mill. In the present study, the preventive effects of the aqueous extract (water-soluble) and residue (water-insoluble) of Matcha on the antioxidant status and lipid and glucose levels in mice fed a high-fat diet were investigated. Mice were fed seven different experimental diets for 4 weeks: a normal diet control (NC), a high-fat diet (HF), a high-fat diet with 0.025% Matcha (MLD), a high-fat diet with 0.05% Matcha (MMD), a high-fat diet with 0.075% Matcha (MHD), a high-fat diet with 0.05% Matcha aqueous extracts (ME), and a high-fat diet with 0.05% Matcha residues (MR). It was found that serum total cholesterol (TC) and triglyceride (TG) levels of the MHD group were significantly decreased compared to those of the HF group. Furthermore, in the MHD group, the level of high-density lipoprotein-cholesterol (HDL-C) was elevated, on the contrary the level of low-density lipoprotein-cholesterol (LDL-C) was suppressed. Moreover, Matcha could significantly lower the blood glucose levels, and improve the superoxide dismutase (SOD) activity and malondialdehyde (MAD) contents both in serum and liver; besides, the serum GSH-Px activity indicated that the oxidative stress caused by HF could be reversed by administration of Matcha. These findings suggest that Matcha has beneficial effects through the suppression of the blood glucose (BG) accumulation and promotion of the lipid metabolism and antioxidant activities. Moreover, the water-insoluble part of Matcha is suggested to play an important role in the suppression of diet-induced high levels of lipid and glucose. PMID:26448271

    Since the 1970s, many analytical methods for the detection of illegal growth promoters, such as thyreostats, anabolics, {beta}-agonists and corticosteroids have been developed for a wide range of matrices of animal origin, including meat, fat, organ tissue, urine and faeces. The aim of this study was to develop an analytical method for the determination of ng L{sup -1} levels of estrogens, gestagens, androgens (EGAs) and corticosteroids in aqueous preparations (i.e. drinking water, drinking water supplements), commercially available on the 'black' market. For this, extraction was performed with Bakerbond C{sub 18} speedisk, a technique commonly used in environmental analysis. After fractionation, four fractions were collected using a methanol:water gradient program. Gas chromatography coupled to electron impact multiple mass spectrometry (GC-EI-MS{sup 2}) screening for the EGAs was carried out on the derivatized extracts. For the detection of corticosteroids, gas chromatography coupled to negative chemical ionization mass spectrometry (GC-NCI-MS) was used after oxidation of the extracts. Confirmation was done by liquid chromatography coupled to electrospray ionization multiple mass spectrometry (LC-ESI-MS{sup 2}). The combined use of GC and LC coupled to MS enabled the identification and quantification of anabolics and corticosteroids at the low ng L{sup -1} level. This study demonstrated the occurrence of both androgens and corticosteroids in different commercial aqueous samples.

    Full Text Available Objectives: To determine the aqueous and plasma concentrations of moxifloxacin administered topically alone and with flurbiprofen in patients undergoing cataract surgery. Materials and Methods: A total of 50 subjects scheduled for routine cataract surgery were randomly allocated to two groups (n = 25 each. Group-1 patients were treated with topical moxifloxacin alone: One drop 6 times/day for 3 days before surgery and one drop 4 times on the day of surgery: Group-2 patients were treated with topical moxifloxacin as in Group-1 and with topical flurbiprofen: One drop 4 times/day for 3 days before and on the day of surgery. The interval between two drugs was 30 min for last 3 days and 15 min on the day of surgery. Last dose was administered 1 h before aqueous humor and blood sampling for both the groups. The antibiotic concentration in aqueous humor and plasma were determined by using high performance liquid chromatography. Results: The mean concentration of moxifloxacin in aqueous humor was 1.71 ± 0.82 mg/ml in Group-1 and 2.39 ± 1.34 mg/ml in Group-2. Concentrations of moxifloxacin in aqueous humor were significantly higher in Group-2 than that of Group-1. Conclusion: Flurbiprofen may increase the concentration of moxifloxacin in aqueous humor.

  8. Measurement of underground contamination of non-aqueous phase liquids (NAPLs) on the basis of the radon concentration in ground level air

    International Nuclear Information System (INIS)

    It was investigated whether measurements of radon concentrations in ground level air are a suitable method of detecting sub-surface soil contamination with non-aqueous phase liquids (NAPLs). The working postulation was that, due to the very high solubility of radon in NAPLs, and the resulting accumulation of radon in NAPLs, radon exhalation to the ground level air in the proximity of such NAPL contamination should be locally reduced, thus indicating contamination of sub-surface soils with NAPLs. The research work reported was to verify the working theory by way of experiments, and to finally develop a reliable detection method for NAPL contaminations. The investigations comprised theoretical studies, laboratory experiments, experiments in defined soil columns, and extensive field studies

    There is extensive evidence that emotional information is better remembered than neutral information across long delays, especially if the delay interval contains an opportunity for sleep. However, as prior studies have focused on memory for negative stimuli, it is unclear whether positive memories benefit from time and sleep as well. To investigate the consolidation of positive memories, the current study examined differences in memory for humorous and non-humorous cartoons. While prior evidence demonstrates that humorous information is preferentially remembered relative to non-humorous information over brief delays, it is unknown whether this benefit lasts across longer delay intervals or whether sleep is important for lasting humor memories to form. Thus, we tested memory for 27 cartoons across 12-h delay periods containing either sleep or wakefulness. Results indicate that humor's enhancing effect on recall memory is robust across a 12-h delay and that a period of sleep facilitates this effect over wakefulness when cartoons are novel to participants and ranked based on subjective emotional ratings. Further, in accordance with previous studies that reveal diminished emotional reactivity to stimuli following sleep, in a supplemental experiment, we found that sleep reduced subjective ratings of humor, arousal, and positivity of humorous cartoons. These findings provide preliminary evidence that sleep's impact on negative emotional memory consolidation and emotional reactivity can be extended to positive stimuli as well. PMID:24337230

    Language humor is a usual phenomenon in human communication. It is an interdisciplinary subject connected with a wide range of learning. Up to now, a great deal of research has been done from the viewpoint of psychology and sociology. In the field of linguistics, some explorations have already been made in regard to its semantic and rhetorical aspects, but due attention has not been paid to it in pragmatics in that in everyday verbal communication, humorous utterances are easy to enjoy but hard to define. Apart from its capability of laughter-making, language humor is more often than not, produced to implicitly perform some communicative functions, not achievable by explicit expressions. This the - sis, based on the fruitful studies of humor, attempts to investigate the mechanisms of English humor from the perspective of a new theory 一 Co- operative Principle.

    International Nuclear Information System (INIS)

    Laboratory results of a comprehensive regulatory performance test program, using an extruded bitumen and a surrogate, sodium nitrate-based waste, have been compiled at the Oak Ridge National Laboratory (ORNL). The testing has shown that the relatively viscous form of oxidized bitumen that was used has been able to meet all performance requirements. Using a 53-mm Werner and Pfleiderer extruder, operated by personnel of WasteChem Corporation of Paramus, New Jersey, laboratory-scale, molded samples of ASTM D312, type III, air-blown bitumen were prepared for laboratory performance testing. A surrogate, low-level, mixed liquid waste, formulated to represent an actual on-site waste at ORNL, was used. The mixed liquid waste contained approximately 30 wt % sodium nitrate, in addition to eight heavy metals, cold cesium, and strontium. Samples tested contained three levels of waste loading: that is, 40, 50, and 60 wt % salt. Performance test results include the 90-day American Nuclear Society (ANS) 16.1 leach test, with leach indices reported for all cations and anions, in addition to the EP toxicity test, at all levels of waste loading. Additionally, test results presented include the unconfined compressive strength and surface morphology utilizing scanning electron microscopy (SEM). Data presented include correlations between waste form loading and test results, in addition to their relationship to regulatory performance requirements

  1. Children’s Understanding of Self-Focused Humor Styles

    James, Lucy Amelia; Fox, Claire Louise

    2016-01-01

    It has been proposed that four main styles of humor exist, two which are thought to be adaptive (affiliative, self-enhancing) and two which are thought to be maladaptive (aggressive, self-defeating). Whilst the existence of these four humor styles has been supported in older children, it is suggested that for younger children, self-enhancing and self-defeating humor may develop at a later point. To investigate this further, the current research involved five semi-structured paired interviews with children aged eight to eleven years to explore the use and understanding of self-enhancing and self-defeating humor in this age group. Findings indicated that use of both self-enhancing and self-defeating humor were apparent in some children, but not all. It therefore seems appropriate that attempts to investigate humor in this age group should aim to include all four styles of humor. The current research also demonstrated the value of paired interviews when carrying out this sort of research with children. PMID:27547258

    Full Text Available Although there are many clinical programs designed to bring humor into pediatric hospitals, there has been very little research with children or adolescents concerning the specific utility of humor for children undergoing stressful or painful procedures. Rx Laughter™, a non-profit organization interested in the use of humor for healing, collaborated with UCLA to collect preliminary data on a sample of 18 children aged 7–16 years. Participants watched humorous video-tapes before, during and after a standardized pain task that involved placing a hand in cold water. Pain appraisal (ratings of pain severity and pain tolerance (submersion time were recorded and examined in relation to humor indicators (number of laughs/smiles during each video and child ratings of how funny the video was. Whereas humor indicators were not significantly associated with pain appraisal or tolerance, the group demonstrated significantly greater pain tolerance while viewing funny videos than when viewing the videos immediately before or after the cold-water task. The results suggest that humorous distraction is useful to help children and adolescents tolerate painful procedures. Further study is indicated to explore the specific mechanism of this benefit.

    Hexagonal c-axis oriented zinc oxide (ZnO) nanorods (NRs) with 120-300 nm diameters are synthesized via the low temperature aqueous chemical route at 80 °C on silver-coated glass substrates. The influence of varying the precursor solutions stirring durations on the concentration and spatial distributions of deep level defects in ZnO NRs is investigated. Room temperature micro-photoluminesnce (μ-PL) spectra were collected for all samples. Cathodoluminescence (CL) spectra of the as-synthesized NRs reveal a significant change in the intensity ratio of the near band edge emission (NBE) to the deep-level emission (DLE) peaks with increasing stirring durations. This is attributed to the variation in the concentration of the oxygen-deficiency with increasing stirring durations as suggested from the X-ray photoelectron spectroscopy analysis. Spatially resolved CL spectra taken along individual NRs revealed that stirring the precursor solutions for relatively short duration (1-3 h), which likely induced high super saturation under thermodynamic equilibrium during the synthesis process, is observed to favor the formation of point defects moving towards the tip of the NRs. In contrary, stirring for longer duration (5-15 h) will induce low super saturation favoring the formation of point defects located at the bottom of the NRs. These findings demonstrate that it is possible to control the concentration and spatial distribution of deep level defects in ZnO NRs by varying the stirring durations of the precursor solutions.

    2012-01-01

    This article investigates the effects of different emotional appeals in HIV/AIDS prevention campaigns using printed advertisements. More specifically, it examines the effectiveness of humor appeal compared with shock and fear appeals. The authors experimentally test the level of attention drawn and the spontaneous recall arising when young Italian adults are shown different HIV/AIDS prevention campaigns. Findings show that humor appeals are less effective than fear and shock appeals, evidencing the failures in HIV/AIDS prevention campaigns in Italy, a country where the former communication strategy has been used in substantive ways. The results also indicate the higher effectiveness of fear appeals (over shock and humor) in printed HIV/AIDS advertising campaigns. The implications of these results for further studies and for improving the design, implementation, and evaluation of HIV/AIDS campaign efforts are also discussed. PMID:22694065

    Humor (and related concerns such as the nature of comedy and of laughter) is an enigmatic subject that has perplexed our greatest thinkers from Aristotle’s time to the present. There are four competing theories that explain humor, each of which argues that all humor is based on: superiority, incongruity, cognitive problems in processing humor and psychoanalytic perspectives (such as masked aggression).

    2000-09-01

    The effect of the aqueous extract of Plantago ovata (PO) (Plantaginaceae) consisting of a mixture of polysaccharides and glycoside on humoral immune responses was studied. In rabbits, after oral administration of PO (0.5 g/kg) a significant decrease in anti-HD antibody titre was observed in primary response. Intraperitoneal injection of 0.25 g/kg of PO in mice prior to immunisation with sheep red blood cells (SRBC) resulted in a significant decrease in hemagglutinating antibody (HD) titre. Oral administration and intraperitoneal injection of 0.25 and 0.5 g/kg of PO resulted in a significant increase in white blood cells (WBC) and spleen leukocytes counts. The spleen weight also increased with intraperitoneal injection (0.25 and 0.5 g/kg) and oral administration of 0.5 g/kg of PO. Present results indicate that PO can suppress the humoral immune responses, especially in primary immune response. PMID:10967483

    Full Text Available Abstract Background It seems that the core neural regions and cognitive processes implicated in obsessive-compulsive disorder (OCD pathophysiology may overlap with those involved in humor appreciation. However, to date, there have been no studies that have explored humor appreciation in OCD. The purpose of the present work was to investigate humor appreciation in a group of patients with OCD. Methods We examined 25 patients with OCD and 25 healthy controls, matched by age, education, and gender. We administered Penn's Humor Appreciation Test (PHAT, a computerized test comprising captionless cartoons by Mordillo. Each set of stimuli consisted of two almost identical drawings, one of which was funny due to the alteration of a detail in the cartoon, whereas the other was not funny. Severity of psychopathology was evaluated with the Yale-Brown Obsessive Compulsive Scale (Y-BOCS. Results No significant effect for group, gender or group × gender interaction was found on the PHAT scores. In OCD patients, humor appreciation was not significantly associated with age of onset, duration of illness, and obsessions, but correlated significantly with compulsions. Conclusions Humor appreciation, based on captionless cartoons in OCD, does not seem to be deficient compared to healthy subjects but may be related to illness characteristics.

    2016-01-01

    This study assessed the concurrent and prospective associations between psychosocial adjustment and four humor styles, two of which are adaptive (affiliative, self-enhancing) and two maladaptive (aggressive, self-defeating). Participants were 1,234 adolescents (52% female) aged 11-13 years, drawn from six secondary schools in England. Self-reports of psychosocial adjustment (loneliness, depressive symptomatology, and self-esteem) and humor styles were collected at two time points (fall and summer). In cross-lagged panel analyses, self-defeating humor was associated with an increase in both depressive symptoms and loneliness, and with a decrease in self-esteem. In addition, depressive symptoms predicted an increase in the use of self-defeating humor over time, indicating that these may represent a problematic spiral of thoughts and behaviors. Self-esteem was associated with an increase in the use of affiliative humor over the school year but not vice-versa. These results inform our understanding of the ways in which humor is associated with psychosocial adjustment in adolescence. PMID:27547255

    Full Text Available In positive psychology, humor has been identified as one of 24 character strengths considered ubiquitously important for human flourishing. Unlike the other strengths, humor was a late addition to this classification system and its status as a strength continues to be somewhat controversial. Therefore, the first purpose of this study was to explore the associations between humor and several outcome variables of relevance to positive psychology (happiness, routes to happiness, resilience, and morality. The second purpose was to explore how best to conceptualize and measure humor as a character strength by comparing the Values in Action Inventory of Strengths (VIA-IS Humor Scale with the Humor Styles Questionnaire (HSQ in their ability to predict the outcome variables. A sample of 176 participants completed questionnaires assessing the humor and positive psychology constructs. The results indicated that the humor measures significantly predicted most of the outcome variables, supporting the importance of humor in positive psychology. Furthermore, although the VIA-IS Humor scale and positive humor styles on the HSQ showed considerable overlap, the negative humor styles added significantly to the prediction of outcome variables beyond these positive humor measures, supporting the importance of assessing maladaptive as well as adaptive uses of humor in research on positive psychology. These findings suggest that the HSQ may be a more useful measure than the VIA-IS Humor scale in future research in this field.

    2015-06-01

    This research summarizes the knowledge generated in social psychology and positive psychology about the relationship between humor styles, personality and wellbeing. Specifically, a meta-analysis was performed with the results of 15 studies on humor styles measured by the Humor Styles Questionnaire (Martin, Puhlik-Doris, Larsen, Gray & Weir, 2003) in correlation with the personality traits measured by the Big Five Personality model (measured with different scales). Following the steps presented by Rosenthal (1991) for meta-analysis in the case of correlational research, we calculated the total mean r as an indicator of effect size. Results show that affiliative humor has a strong and homogeneous relation to neuroticism and extraversion. The homogeneity and heterogeneity found between variables and possible explanations are discussed in the conclusion. PMID:25786353

    Full Text Available The nervous system is the target for acute encephalitic viral infections, as well as a reservoir for persisting viruses. Intrathecal antibody (Ab synthesis is well documented in humans afflicted by infections associated with neurological complications, as well as the demyelinating disease, multiple sclerosis. This review focuses on the origin, recruitment, maintenance, and biological relevance of Ab-secreting cells (ASC found in the central nervous system (CNS following experimental neurotropic RNA virus infections. We will summarize evidence for a highly dynamic, evolving humoral response characterized by temporal alterations in B cell subsets, proliferation, and differentiation. Overall local Ab plays a beneficial role via complement-independent control of virus replication, although cross or self-reactive Ab to CNS antigens may contribute to immune-mediated pathogenesis during some infections. Importantly, protective Ab exert anti-viral activity not only by direct neutralization, but also by binding to cell surface-expressed viral glycoproteins. Ab engagement of viral glycoproteins blocks budding and mediates intracellular signaling leading to restored homeostatic and innate functions. The sustained Ab production by local ASC, as well as chemokines and cytokines associated with ASC recruitment and retention, are highlighted as critical components of immune control.

  6. Eosinophils: important players in humoral immunity.

    Science.gov (United States)

    Berek, C

    2016-01-01

    Eosinophils perform numerous tasks. They are involved in inflammatory reactions associated with innate immune defence against parasitic infections and are also involved in pathological processes in response to allergens. Recently, however, it has become clear that eosinophils also play crucial non-inflammatory roles in the generation and maintenance of adaptive immune responses. Eosinophils, being a major source of the plasma cell survival factor APRIL (activation and proliferation-induced ligand), are essential not only for the long-term survival of plasma cells in the bone marrow, but also for the maintenance of these cells in the lamina propria which underlies the gut epithelium. At steady state under non-inflammatory conditions eosinophils are resident cells of the gastrointestinal tract, although only few are present in the major organized lymphoid tissue of the gut - the Peyer's patches (PP). Surprisingly, however, lack of eosinophils abolishes efficient class-switching of B cells to immunoglobulin (Ig)A in the germinal centres of PP. Thus, eosinophils are required to generate and to maintain mucosal IgA plasma cells, and as a consequence their absence leads to a marked reduction of IgA both in serum and in the gut-associated lymphoid tissues (GALT). Eosinophils thus have an essential part in long-term humoral immune protection, as they are crucial for the longevity of antibody-producing plasma cells in the bone marrow and, in addition, for gut immune homeostasis.

    Full Text Available This paper discusses humorous stories collected in the village of Brekovo near Arilje; the stories were created in the first half of the 20th century and noted down by Momčilo Jovanović, a villager from Brekovo. Later on, in the 1980's, the stories were passed down to the author of this paper. These narrations are mostly short stories and anecdotes; in a very realistic fashion, the stories depict life and culture of the Dinaric race from old Vlah - Zlatibor cultural area, namely, the type of person also known as "Era", well-known for its wittiness, smartness and wisdom. Based on the analysis of seven Era-stories, the author identified the social and cultural values highlighted in the stories (such as attitudes toward authorities intergenerational relationship, status of women, power relations between townsmen and peasants, propensity toward justice and truth. In summary, the stories document the mutual influence between traditional culture and the Era personality in this particular rural region; therefore, they could contribute to studies on character traits of the inhabitants in a given area of western Serbia.

    Ruch, Willibald; Heintz, Sonja

    2016-01-01

    The Humor Styles Questionnaire (HSQ; Martin et al., 2003) is one of the most frequently used questionnaires in humor research and has been adapted to several languages. The HSQ measures four humor styles (affiliative, self-enhancing, aggressive, and self-defeating), which should be adaptive or potentially maladaptive to psychosocial well-being. The present study analyzes the internal consistency, factorial validity, and factorial invariance of the HSQ on the basis of several German-speaking samples combined (total N = 1,101). Separate analyses were conducted for gender (male/female), age groups (16–24, 25–35, >36 years old), and countries (Germany/Switzerland). Internal consistencies were good for the overall sample and the demographic subgroups (.80–.89), with lower values obtained for the aggressive scale (.66–.73). Principal components and confirmatory factor analyses mostly supported the four-factor structure of the HSQ. Weak factorial invariance was found across gender and age groups, while strong factorial invariance was supported across countries. Two subsamples also provided self-ratings on ten styles of humorous conduct (n = 344) and of eight comic styles (n = 285). The four HSQ scales showed small to large correlations to the styles of humorous conduct (-.54 to .65) and small to medium correlations to the comic styles (-.27 to .42). The HSQ shared on average 27.5–35.0% of the variance with the styles of humorous conduct and 13.0–15.0% of the variance with the comic styles. Thus–despite similar labels–these styles of humorous conduct and comic styles differed from the HSQ humor styles. PMID:27547259

  10. Trace level determination of precious metals in aqueous medium, U, Th and Zr based nuclear materials by ICP-AES and EDXRF - a comparative study

    International Nuclear Information System (INIS)

    A comparative study was carried out to determine Ag, Au and Pt in aqueous samples, uranium, zirconium, and thorium based nuclear fuels and associated materials by CCD based ICP-AES and EDXRF. In ICP-AES, the spectral interference of U, Th, Zr matrices on trace level determination of Ag, Au and Pt were studied for different analytical lines of these analytes. The analytical performance of different lines including detection limits, sensitivity, linear dynamic range etc were studied both by ICP-AES and EDXRF. Though EDXRF technique was known its non destructive nature, the overall analytical performance of ICP-AES technique was found to be superior to EDXRF. Based on the spectral contribution from emission rich matrix elements and the analytical performance of different analytical lines of these analytes, a method was developed for direct determination of these analytes by ICP-AES without chemical separation. The method was validated with synthetic samples and compared with EDXRF technique and conventional ICP-AES technique where the major matrix was chemically separated using suitable organic phase containing selective ligands. The ICP-AES method for direct determination of analytes without chemical separation was found to be simple, less time consuming, without generation of organic waste with acceptable analytical performance

    Full Text Available PURPOSE: This study investigates the differential aqueous concentrations of interleukin 6, 8, 1β (IL-6, IL-8, IL-1β, respectively, serum amyloid A (SAA, transforming growth factor (TGF-β, basic fibroblast growth factor (bFGF, and vascular endothelial growth factor (VEGF in eyes with macular edema as a result of a branch retinal vein occlusion (BRVO or central retinal vein occlusion (CRVO. PRINCIPAL FINDINGS: Significantly higher concentrations of IL-6, IL-8, IL-1β, TGF-β, bFGF, SAA, and VEGF were found in the aqueous humor of CRVO and BRVO patients than in the aqueous humor of control patients. A significant correlation was observed between the concentration of bFGF and the inner central macular thickness (CMT of BRVO patients (r = 0.688; P = 0.02. A significant correlation was observed between the concentration of SAA and both the full and outer CMT of the ischemic group (r = 0.545 and 0.683, respectively; P = 0.04 and 0.01, respectively. In the non-ischemic group, the level of IL-6 was significantly associated with inner CMT (r = 0.560; P = 0.03. The full and outer CMT was significantly reduced in CRVO patients when compared with BRVO patients (P = 0.02 and 0.02, respectively after injection of intravitreal bevacizumab (IVB at 4 weeks. SIGNIFICANCE: Serum amyloid A as a major protein involved in the acute and chronic stages of inflammation, and IL-6 and bFGF were significantly associated with the extent of macular edema in patients with RVO. Besides VEGF, other inflammatory cytokines and angiogenesic factors may be associated with RVO. This finding may have implications for the medical treatment of RVO.

  13. Comparison of humoral response in sheep to Fasciola hepatica and Fasciola gigantica experimental infection

    2004-06-01

    Full Text Available Humoral response of sheep to F. gigantica was compared with the well known humoral response to F. hepatica, in order to explain the difference of susceptibility of sheep to these two parasites. In this work, a lesser susceptibility of sheep to F. gigantica than to F. hepatica infection was confirmed. Humoral response to F. hepatica infection is similar to that previously described by several authors. IgG level of F. gigantica infected sheep increased from week 2 post-infection (2WPI and displayed a peak at 13WPI. F. gigantica excretory-secretory products (FgESP analyzed by SDS-PAGE showed at least 31 bands from 12.0 to 127.6 kDa in FgESP. Western blot indicated that F. gigantica infected sheep sera recognized, in FgESP, at least 30 antigens from 7.8 to 119.2 kDa of which 12 major bands recognized after OWPI. In FhESP and FgESP, F. hepatica infected sheep serum reacted only with the lower molecular mass antigens, while F. gigantica infected sheep serum reacted with the lower and the higher molecular mass antigens. These differences of antigenic recognition might be associated with the difference of susceptibility of sheep. Further investigation must be done to study the mechanism of resistance between the sheep infected with F. hepatica or F. gigantica.

    Full Text Available OBJETIVO: Avaliar as relações entre o uso agudo e crônico de cannabis e alterações do humor. MÉTODO: Os artigos foram selecionados por meio de busca eletrônica no indexador PubMed. Capítulos de livros e as listas de referências dos artigos selecionados também foram revisados. RESULTADOS: Observam-se elevados índices de comorbidade entre abuso/dependência de cannabis e transtornos afetivos em estudos transversais e em amostras clínicas. Estudos longitudinais indicam que, em longo prazo, o uso mais intenso de cannabis está relacionado com um risco maior de desenvolvimento de doença bipolar e, talvez, depressão maior em indivíduos inicialmente sem quadros afetivos; porém, os mesmos não encontraram maior risco de uso de cannabis entre aqueles com mania ou depressão sem esta comorbidade. Outra importante observação é que o uso de substâncias psicoativas em bipolares pode estar associado a uma série de características negativas, como dificuldade na recuperação dos sintomas afetivos, maior número de internações, piora na adesão ao tratamento, risco aumentado de suicídio, agressividade e a uma pobre resposta ao lítio. Tratamentos psicossociais e farmacológicos são indicados para o manejo da comorbidade entre cannabis e transtornos afetivos. CONCLUSÃO: As relações entre o uso de cannabis e alterações do humor são observadas tanto epidemiologicamente quanto nos contextos clínicos.OBJECTIVE: Evaluate the relationship between acute and chronic use of cannabis and mood changes. METHOD: Articles were selected by electronic search in PubMed. Chapters in books and reference lists of selected articles were also reviewed. As the research did not involve humans, there was no evaluation by a Research Ethics Committee.

    2015-01-01

    Humor plays an indispensable part in human communication. This thesis is a tentative analysis of verbal humor under-standing within the framework of Relevance Theory. This paper, using The Big Bang Theory as a corpus, analyzes the humor gener-ated in the cognitive process of searching for relevance. According to the Relevance Theory, the understanding of humor is a pro-cess in which the hearer finds"relevance"in what seems"irrelevant". The author hopes that this analysis can help more people un-derstand and appreciate the humor in The Big Bang Theory. And meanwhile their personal sense of humor can also be improved.

    2014-01-01

    Humor study enjoys a long history with a variety of theories and methods. Among them, the pragmatic approach is a relatively new and vigorous perspective. Scholars have adopted the cooperative principle and relevance theory to explain humor. However, as to studying humor from the perspective of pragmatic presupposition, very few researches have been done in this regard. Such being the case, this paper will use presupposition as a tool to analyze humor in Lost in Thailand which is a sensational comedy in China. By analyzing cases from this film, the paper aims to explore how presupposition functions in the production of humorous effect, and to provide some new insights into humor study.

    Science.gov (United States)

    Southam, Marti; Schwartz, Kathleen Barker

    2004-01-01

    SUMMARY Humor use in education has been studied in fields such as psychology and nursing. Research has demonstrated that effective educational humor needs to be integrated into the topic and used in moderation. Used appropriately, humor can gain attention, facilitate creative thinking and memory, motivate students to attend class, and promote learning outcomes. No studies were located in the occupational therapy literature that specifically related to humor as an aspect of teaching. The purpose of this article is to explore the merits of humor as an educational tool and to give examples of ways that occupational therapy faculty and clinical instructors can employ humor.

    Objective The protein Hwp1, expressed on the pathogenic phase of Candida albicans, presents sequence analogy with the gluten protein gliadin and is also a substrate for transglutaminase. This had led to the suggestion that C. albicans infection (CI) may be a triggering factor for Celiac disease (CeD) onset. We investigated cross-immune reactivity between CeD and CI. Methods Serum IgG levels against recombinant Hwp1 and serological markers of CeD were measured in 87 CeD patients, 41 CI patients, and 98 healthy controls (HC). IgA and IgG were also measured in 20 individuals from each of these groups using microchips sensitized with 38 peptides designed from the N-terminal of Hwp1. Results CI and CeD patients had higher levels of anti-Hwp1 (p=0.0005 and p=0.004) and anti-gliadin (p=0.002 and p=0.0009) antibodies than HC but there was no significant difference between CeD and CI patients. CeD and CI patients had higher levels of anti-transglutaminase IgA than HC (p=0.0001 and p=0.0039). During CI, the increase in anti-Hwp1 paralleled the increase in anti-gliadin antibodies. Microchip analysis showed that CeD patients were more reactive against some Hwp1 peptides than CI patients, and that some deamidated peptides were more reactive than their native analogs. Binding of IgG from CeD patients to Hwp1 peptides was inhibited by γIII gliadin peptides. Conclusions Humoral cross-reactivity between Hwp1 and gliadin was observed during CeD and CI. Increased reactivity to Hwp1 deamidated peptide suggests that transglutaminase is involved in this interplay. These results support the hypothesis that CI may trigger CeD onset in genetically-susceptible individuals. PMID:25793717

Information on predictors of these humor styles in turn enhances the ability to predict the effect on well-being.Methods: We examined the relationships between interpersonal competence, self-esteem, and different styles of humor, while also examining the contributions of age and gender. Participants (n = 201 aged 18–63 years completed the Rosenberg Self-Esteem Inventory, the Interpersonal Competence Questionnaire, and the Humor Styles Questionnaire, and gave demographic information.Results: High self-esteem was associated with higher use of affiliative, aggressive, and self-enhancing humor styles, but lower use of self-defeating humor. High interpersonal competence predicted greater use of affiliative humor, whereas low interpersonal competence predicted greater use of aggressive humor. Further analyses showed that initiation competence predicted affiliative humor (positively but both initiation competence (positively and conflict management competence (negatively predicted aggressive humor.Conclusion: The findings that both self-esteem and initiation competence contribute to use of aggressive humor add to knowledge of who is likely to use this potentially harmful humor style. We conclude that a readiness to initiate humorous interactions is not on its own a general and positive attribute contributing to “good” humor.Keywords: self-esteem, interpersonal competence, humor styles, differential effects

  1. Influence of Some Pesticides on Humoral and Cellular Immunity of Exposed Workers in Pesticides Industries

    International Nuclear Information System (INIS)

    Pesticide poisoning is a major public health problem in developing countries. In most of these countries organophosphate pesticides constitute the most widely used pesticides. The main toxicity of OPs is neurotoxicity, which is caused by the inhibition of acetylcholinesterase. OPs also affect the immune response, including effects on cellular and humoral immunity. Our study examined the effect of organophosphorus compounds on humoral and cellular immunity of exposed workers in pesticides industries. The study was conducted into 40 subjects. They were 2 groups; 20 exposed workers from Gharbeia and Kafr Elsheikh at 2008 and 2009 and 20 unexposed individuals as a control group at the same period of time. We examined some immune parameters; pseudocholinesterase, WBCs count, CD4%, CD8%, CD4/CD8, CD56%, Interleukin 2, IgG and IgM. Also we take history and clinical examination for them. We reported a highly significant decrease in pseudo cholinesterase level among the exposed group in comparison to the control group, highly significant increase in percentage of CD8 in the exposed group in comparison to control group, highly significant decrease in CD4 / CD8 ratio in the exposed group in comparison to control group, highly significant decrease in percentage of CD56 in the exposed group in comparison to control group and a highly significant increase in IgG level in the exposed group in comparison to control group. On the other hand, we reported no significant change in white blood cells count between the exposed and control groups, no significant change in percentage of CD4 among the exposed and control group, no significant change in Interleukin 2 level among the exposed and control group and no significant change in IgM level among the exposed and control group. We concluded that pesticides extensively affect the humoral and cellular immune system of occupationally exposed workers.

    Pride and Prejudice, published in 1813, is the most influential work of British female writer Jane Austen (1775-1817). By analyzing Jane Austen's representative novel, Pride and Prejudice, we are convinced by the excellent humor and irony used in it. Irony in Pride and Prejudice is mainly embodied in Austen's verbal irony, situational irony and dramatic irony. Under the perspective of stylistics, this paper analyzes dialogues, descriptive and commentary language and the arrangement of the whole plots of Austen's Pride and Prejudice to show how the different tones of humor and irony are reflected in the novel. This paper also focuses on the significance in portraying the characteristics of the roles and theme performance of humor and irony used in Pride and Prejudice, which help us to appreciate the satire literature.

    2016-03-01

    Humor is, from a psychological point of view, a complex process involving cognitive, affective, interspersonal and social elements in a interpersonal context. Its cognitive core is based on the perception of incongruity between two related inconsistent or contradictory mental representations. The total or partial resolution of incongruity in a playful frame is associated with a specific positive emotion, which characteristics and intensity are determined by the structure of the humoristic stimulus more than its content, and the personal and social contexts. Main theories of humor are reviewed as well as its development, its cognitive and affective correlates, and the influence of genre, age and personality. PMID:27005341

    2016-01-01

    Throughout the literature, humor has demonstrated positive effects on memory and learning, as well as physiological and psychological well being. Research has described improvements in communication and trust through the use of humor in the nurse-patient relationship. The utilization of humor with certain populations, including those with anxiety disorders, cancer patients and mood disorders has also been widely described in the literature but little research has been conducted with humor use in patients' recovery from substance use disorders. This population might benefit from the thoughtful applications of humor to promote laughter and mirth as well as learning recovery principles. A review of the humor theories, theoretical processes and humor styles are discussed for their use in individuals with substance use disorders, in particularly for early recovery engagement in 12 step programs and other recover support social networks. The application of humor in efforts to support recovery with substance use disorder patients is worth investigating further. PMID:27347254

    2014-01-01

    This study tested the effect of humor in one particular type of print advertisement: the preventive health ads for three topics (alcohol, tobacco, obesity). Previous research using commercial ads demonstrated that individuals' attention is spontaneously attracted by humor, leading to a memory advantage for humorous information over nonhumorous information. Two experiments investigated whether the positive effect of humor can occur with preventive health ads. In Experiment 1, participants observed humorous and nonhumorous health ads while their viewing times were recorded. In Experiment 2, to compare humorous and nonhumorous ads, the memory of health messages was assessed through a recognition task and a convincing score was collected. The results confirmed that, compared to nonhumorous health ads, those using humor received prolonged attention, were judged more convincing, and their messages were better recognized. Overall, these findings suggest that humor can be of use in preventive health communication. PMID:24160572

    2010-06-01

    Full Text Available The present study investigates humor appreciation of aggressive cartoons in relation to gelotophobia, gelotophilia, and katagelasticism. These traits were described to have a peculiar relation to laughter-related phenomena, in particular to disparagement humor. 185 participants rated highly aggressive and non-aggressive humorous stimuli for funniness and aversiveness and their scores on the gelotophobia, gelotophilia and katagelasticism scales were measured. The cartoons were controlled for their structural basis, i.e., incongruity-resolution and nonsense humor, as these two types of humor strongly influence the appreciation of humorous stimuli. The results revealed that high scores on gelotophobia lead to higher aversion to aggressive humor, whereas high scores on katagelasticism lead to more enjoyment of aggressive humor with less aversion. Gelotophobia and katagelasticism lead to sensitivity to aggression in humor, which fits the overt behavior of reacting sensitively towards laughter (gelotophobia and enjoying to laugh at others (katagelasticism. Gelotophilia did not predict reactions to either aggressive or non-aggressive humor but did predict more amusement in general: High scorers on gelotophilia seem to be relaxed towards any form of humor, even if it has an aggressive note. This study confirms the three dimensions to have peculiar responses to aggressive types of humor and opens up several questions to be explored in future research.

    Smiling and laughing appear very early during the first year of life, but little is known about how infants come to appraise a stimulus as humorous. This short-term longitudinal study explored infant humor perception from 5 to 7 months of age as a function of parental affect during an absurd event. Using a within-participants design, parents alternated smiling/laughing with emotional neutrality while acting absurdly toward their infants. Group comparisons showed that infants (N = 37) at all ages smiled at the event regardless of parental affect but did so significantly longer at 5 and 6 months, and more often and sooner at 7 months, when parents provided humor cues. Similarly, sequential analyses revealed that after gazing at the event, 7-month-olds were more likely to smile at it only when parents provided humor cues and were comparatively more likely to look away when parents were neutral. Thus, starting at 5 months of age, parental affect influenced infants' affect toward an absurd event, an effect that was magnified at 7 months. These results are discussed in the context of emotional contagion, regulation, and the emergence of social referencing. PMID:25897958

  16. Remediation of alkaline intermediate level radioactive aqueous liquid waste stored along with organic waste at PREFRE Tarapur for ion exchange process: a laboratory scale study

    International Nuclear Information System (INIS)

    Dibutyl phosphate (DBP) and monobutyl phosphate (MBP) are formed during reprocessing of spent fuel as degradation products of Tributyl phosphate (TBP). To maintain the efficiency of TBP solvent during its repeated use, the degraded products are removed by sodium carbonate washing of the solvent. This radioactive sodium carbonate solution is stored in a separate tank along with the exhausted TBP solvent. The presence of degraded products of TBP and their complexes, ion exchange treatment of this waste is creating problems during alpha decontamination step. The present paper deals with the remediation of the aqueous phase of the above waste. For the treatment of the aqueous phase of waste, first the TBP degraded products are required to be removed so that the normal ion exchange treatment can be adopted. (author)

  17. Towards a new structural model of the sense of humor: Preliminary findings

    In this article some formal, content-related and procedural considerations towards the sense of humor are articulated and the analysis of both everyday humor behavior and of comic styles leads to the initial proposal of a four factor- model of humor (4FMH). This model is tested in a new dataset and it is also examined whether two forms of comic styles (benevolent humor and moral mockery) do fit in. The model seems to be robust but further studies on the structure of the sense of humor as a pe...

  20. Humor and Resiliency: Towards a Process Model of Coping and Growth

    Directory of Open Access Journals (Sweden)

    Nicholas A. Kuiper

    2012-08-01

    Full Text Available This article considers how humor may fit within a resiliency perspective. Following a brief overview of resiliency approaches, including selected work on positive psychology, several lines of research that provide initial support for resiliency effects of humor on stress and trauma are highlighted. This work ranges from anecdotal case report descriptions of facilitative humor use in extremely traumatic situations (e.g., paramedics, to more rigorous studies examining moderator and cognitive appraisal effects of humor on psychological well-being. Although these initial findings are quite promising, it is noted that some resiliency-based approaches to humor are limited by a sole focus on humor as a positive attribute. As such, a humor styles model, which acknowledges both the adaptive and maladaptive aspects of humor, is used to describe broader avenues of research within a resiliency perspective. This process orientation to humor use also highlights the importance of both negative and positive emotion regulation in modulating coping and growth. This model is then used to comment on limitations and potential extensions of current resiliency perspectives on humor, including programs and exercises that attempt to train humor use in a facilitative manner.

    Full Text Available Theories about black humor usually regard that it as a contemporary phenomenon and a culmination of the literary modernism and beginning of post-modernism. My intent in this paper is to refute the thesis that the black humor is a modern invention. I am going to prove its existence still in Greek antiquity, quoting and analyzing humorous epitaphs and black humor epigrams. Putting in relation black humor with the joy and humor in religious (fertility and funeral rituals, I am also going to set a question about the attitude to death and life inherent for this kind of humor, arguing that its origin should be searched in the folk tradition.

    This study examined the relationship between humor styles and loneliness among a sample of Hong Kong and Mainland Chinese. A total of 159 Hong Kong undergraduates and 178 Hangzhou undergraduates were recruited to complete a survey composed of the Humor Styles Questionnaire and the Emotional and Social Loneliness Scales. Multiple regression analyses showed that self-defeating humor explained significant variance in both social and emotional loneliness for Hong Kong students, but only in social loneliness for Hangzhou students. Hong Kong students scored significantly higher on aggressive humor and self-defeating humor, and scored significantly lower on affiliative humor and self-enhancing humor than did their counterparts in Hangzhou. This could be attributed to the greater influence of Confucianism in Mainland China than in Hong Kong. PMID:25153950

    In this study we aimed to examine the contents of humor in the Japanese workplace and to understand the effects of humor on mental/physical health and self-evaluation of job performance. Japanese workers (N = 436) responded to questionnaires addressing workplace humor, feelings about workplace, workplace communication, mental/physical health, and perceived job performance. An exploratory factor analysis indicated that there are five types of workplace humor: norm-violating humor, experience-sharing humor workplace-enjoying humor, people-recalling humor, and outside-mocking humor. A covariance structural analysis showed that norm-violating humor and workplace-enjoying humor decreased mental and physical health by promoting both negative feelings in the workplace and self-disclosure about the negative side of work. Results also revealed that experience-sharing humor, people-recalling humor, and outside-mocking humor had a positive effect on the self-evaluation of job performance as well as mental and physical health, by promoting both positive feelings and mutual communication in the workplace. Results suggest that humor in the workplace has various influences on workers depending on the type of workplace humor. PMID:27180510

    Full Text Available In this interview, Dr. Arnie Cann discusses his research and views on the ubiquitous role of humor in psychological health and well-being. The interview begins with Professor Cann recounting how he originally became interested in studying humor. He then reflects on the main findings associated with the wide variety of humor-related studies he has conducted over the years. In doing so, Dr. Cann provides suggestions and ideas for further research investigating the role of humor in health and well-being. Specific topic areas discussed include the use of humor in the workplace and other social domains, personality approaches to humor, humor and interpersonal processes, humor and psychopathology, and humor’s role in dealing with stress and well-being. One of the prominent themes in this interview is the clear recognition of sense of humor as a multi-dimensional construct that includes various components that may either be beneficial or detrimental to well-being. A further important theme is the major distinction between humor as an inherent personality construct versus humor that results from exposure to stimuli (e.g., a comedy film. Comments are also provided by Dr. Cann on how the positive affect stemming from humor may be of particular benefit to the individual. Also discussed is the recent move to more fully integrate contemporary humor research with positive psychology approaches. The interview concludes with Dr. Cann providing several recommendations regarding future theorizing and research on the role of humor in psychological well-being.

    2015-01-01

    Those who work with human trauma often use humor to handle job stressors. Research has demonstrated that lighthearted humor is related to lower secondary traumatic stress scores, while gallows humor has the inverse relationship. This work explores how three types of humor relate to secondary traumatic stress: (a) humor at the expense of victims, (b) humor at the expense of offenders, and (c) humor containing sexual innuendo. Internet crimes against children taskforce personnel completed questionnaires about secondary traumatic stress and coping techniques. Humor at the expense of victims was rarely used, but when it was, it was indicative of higher secondary traumatic stress. There were no relationships between secondary traumatic stress and the use of humor at the expense of offenders or humor containing sexual innuendo. PMID:26301442

  7. The use of 125I-labelled protein A for the detection of humoral immunity of gross murine leukaemia virus

    International Nuclear Information System (INIS)

    A solid-phase radioimmunoassay utilising binding of 125I-labelled protein A to antibodies bound to virus adsorbed onto microtitre plates was shown to be suitable for detection of humoral immunity to Gross murine leukaemia virus (MuLV). The specificity of the reaction was shown by the fact that only homologous or closely related viruses effectively inhibited binding of antibodies to adsorbed virus. With this method a low level of spontaneous humoral immunity was demonstrated in sera from AKR/Crc mice, a strain with high concentrations of endogenous virus, whereas little or no anti-viral activity was found in CBA/H-T6Crc, a subline that does not appear to express MuLV.

    The disease resistance and humoral immunomodulatory effects of vitamin C administered orally to grouper, Epinephelus awoara maintained on a frozen fish diet supplemented with vitamin C at 500, 1000, 1500 and 2000 mg/kg were investigated. After 20 weeks, the growth rates of the groups with high level of vitamin C apparently increased. The untreated fish had symptoms of vitamin C deficiency. The endogenous liver tissue vitamin C levels were found to reflect well the dietary treatments. After intraperitoneal injection or bath challenge with a virulent strain of Vibrio vulnificus, fish fed with high level vitamin C showed significantly higher survival rate compared with the normal control group. Vaccination with formalin inactivated V. vulnificus significantly enhanced the specific antibody production in fish treated with vitamin C, and completely protected from strong bacterial challenge the groups fed on fish with vitamin C 1500 and 2000 mg/kg diet.

  9. Lateralization in appreciation of humor: sex differences vs stimulus effects.

    Gallivan, J

    1997-10-01

    The finding that women rate funnier humorous items with left-ear input, while men give higher ratings with right-ear input has been cited as evidence for a biological basis for sex differences in appreciation of humor. However, in 1991 Gallivan did not find this effect and suggested that the earlier finding could have been due to the use of 'male-oriented' stimuli. In this study, 72 subjects rated the funniness of 32 'female oriented' comedy excerpts, presented monaurally. Women gave higher ratings with right-ear input but men's ratings were not affected by ear of presentation. These findings represent another failure to replicate the earlier-reported hemispheric effect and support the conclusion that it may have been due to the stimuli used. PMID:9347538

    2008-09-01

    Erik H. Erikson wrote three articles when he was in his late-twenties and an up-and-coming member of the psychoanalytic community in Vienna. At the time he wrote these articles, he was in a training psychoanalysis with Anna Freud, teaching at the Heitzing School in Vienna, and learning the Montessori method of teaching. These articles focus on the loss of primary narcissism and the development of the superego (or punitive conscience) in early childhood, especially through the child's conflict with maternal authority. They support the idea that melancholia, with its internalized rage against the mother, is the inevitable outcome of the loss of primary narcissism. I note, however, that the third of these articles makes a case for the restorative role of humor, especially when Freud's view that humor is a function of the superego is taken into account.

    A saponin fraction extracted from Quillaja brasiliensis leaves (QB-90) and a semi-purified aqueous extract (AE) were evaluated as adjuvants in a bovine viral diarrhea virus (BVDV) vaccine in mice. Animals were immunized on days 0 and 14 with antigen plus either QB-90 or AE or an oil-adjuvanted vaccine. Two-weeks after boosting, antibodies were measured by ELISA; cellular immunity was evaluated by DTH, lymphoproliferation, cytokine release and single cell IFN-γ production. Serum anti-BVDV IgG, IgG1 and IgG2b were significantly increased in QB-90- and AE-adjuvanted vaccines. A robust DTH response, increased splenocyte proliferation, Th1-type cytokines and enhanced production of IFN-γ by CD4(+) and CD8(+) T lymphocytes were detected in mice that received QB-90-adjuvanted vaccine. The AE-adjuvanted preparation stimulated humoral responses but not cellular immune responses. These findings reveal that QB-90 is capable of stimulating both cellular and humoral immune responses when used as adjuvant. PMID:27012913

    Yue, Xiao Dong; Hui, Anna Na

    2015-12-01

    Humor is found to be an essential element of creative thinking in Western culture. In Eastern culture, however, the relationship between creativity and humor is ambivalent. This study examined the relationship among humor styles, creative personality traits, and creative thinking abilities. A sample of 118 Chinese undergraduates in Hong Kong was recruited to complete the Humor Styles Questionnaire, the three Creative Personality subscales of the Chinese Personality Assessment Inventory-2 (CPAI-2), and the Verbal Test of the Wallach-Kogan Creativity Tests. Results show that humor styles are uncorrelated with creative thinking abilities of flexibility, fluency, and originality, but affiliative humor and aggressive humor are correlated with creative personality traits of novelty and diversity. A hierarchical multiple regression shows that both humor styles and creative personality traits of novelty and diversity account for non-significant variance on creative thinking abilities. These findings largely support a hypothesized non-association between humor styles and creative measures. They also pose a sharp contrast to findings obtained in the West, in which humor styles are typically correlated with both creative thinking abilities and creative personality traits. PMID:26595303

    Full Text Available Patients with organic acidemia are prone to different infections, which lead to acidosis episodes. Some studies have evaluated the status of immune system in acidotic phase in these patients, but to the best of our knowledge no study has evaluated the immune system in non-acidotic phase of the disease. In this study, thirty-one patients with organic acidemia were enrolled. For evaluation of humoral immunity, serum IgA, IgG, IgE, IgM, isohemaggltuinin titer, anti tetanus and anti diphtheria IgG were measured. For screening of complement deficiencies, serum C3, C4, and CH50 were assessed. Eleven patients had Maple Syrup Urine Disease (MSUD, 10 had methylmalonic acidemia, 5 had isovaleric acidemia, 4 had glutaric aciduria, and 1 had propionic acidemia. Serum IgM level was less than normal in 2 patients. Serum isohemagglutinin titer was less than 1:8 in 2 other patients. IgA, IgE, and IgG were within normal range for all patients. Anti tetanus and anti diphtheria IgG levels were low in two patients with MSUD. No significant relationship was found between any of the measured parameters and history of recurrent admissions, recurrent infections and the type of their diseases. Five patients had high C3 level, 4 had high C4 level, and 5 had high CH50 percentage. Totally, 10 patients had high complement level, but no remarkable connection was noted between the type of the disease and complement level. Minor insignificant deficiencies in humoral immunity in non-acidotic phase of organic acidemia were found. Some components of complement system showed increase in some patients, which might be due to decreased pH in extracellular fluid.

    The authors aimed to repair and regenerate articular cartilage with layered chondrocyte sheets, produced using temperature-responsive culture dishes. The purpose of this study was to investigate the humoral factors produced by layered chondrocyte sheets. Articular chondrocytes and synovial cells were harvested during total knee arthroplasty. After co-culture, the samples were divided into three groups: a monolayer, 7 day culture sheet group (group M); a triple-layered, 7 day culture sheet group (group L); and a monolayer culture group with a cell count identical to that of group L (group C). The secretion of collagen type 1 (COL1), collagen type 2 (COL2), matrix metalloproteinase-13 (MMP13), transforming growth factor-β (TGFβ), melanoma inhibitory activity (MIA) and prostaglandin E2 (PGE2) were measured by enzyme-linked immunosorbent assay (ELISA). Layered chondrocyte sheets produced the most humoral factors. PGE2 expression declined over time in group C but was significantly higher in groups M and L. TGFβ expression was low in group C but was significantly higher in groups M and L (p<0.05). Our results suggest that the humoral factors produced by layered chondrocyte sheets may contribute to cartilaginous tissue repair and regeneration. PMID:23165985

    The neurophysiological study of emotion regulation focused on the strategy of reappraisal-i.e., the cognitive reinterpretation of a stimulus. Reappraisal reduces emotional expression, the experience of both negative and positive feelings, and the amplitude of an event-related potential (ERP)-the late positive potential (LPP). In contrast, the strategy of expressive suppression (ES), being the inhibition of emotional expression, has been reported to reduce subjective feelings of positive, but not negative emotion, and has not yet been investigated with ERPs. We focused on the LPP to assess the correlates of ES in the context of humor perception. Twenty-two female participants rated sequences of humorous (H) and non-humorous (NH) pictures, while their zygomaticus muscle was recorded. A spontaneous (SP) condition, in which participants attended naturally to the pictures, resulted in higher ratings of funniness, increased smiling, and increased LPP amplitude for H compared to NH stimuli. An ES condition, in which participants suppressed their facial reactions, resulted in reduced smiling, without affecting subjective ratings. LPP amplitude did not differ between H and NH stimuli during ES, suggesting equal allocation of processing resources to both stimuli. These results suggest that, similarly to reappraisal, ES modifies the way the brain processes positive emotional stimuli. PMID:22369232

    Since the start of the 21st century, the investigation of various psychological aspects of humor and laughter has become an increasingly prominent topic of research. This growth can be attributed, in no small part, to the pioneering and creative work on humor and laughter conducted by Professor Rod Martin. Dr. Martin's research interests in humor and laughter began in the early 1980s and continued throughout his 32 year long career as a professor of clinical psychology at the University of Western Ontario. During this time, Dr. Martin published numerous scholarly articles, chapters, and books on psychological aspects of humor and laughter. Professor Martin has just retired in July 2016, and in the present interview he recounts a number of research highlights of his illustrious career. Dr. Martin's earliest influential work, conducted while he was still in graduate school, stemmed from an individual difference perspective that focused on the beneficial effects of sense of humor on psychological well-being. This research focus remained evident in many of Professor Martin's subsequent investigations, but became increasingly refined as he developed several measures of different components of sense of humor, including both adaptive and maladaptive humor styles. In this interview, Dr. Martin describes the conceptualization, development and use of the Humor Styles Questionnaire, along with suggestions for future research and development. In doing so, he also discusses the three main components of humor (i.e., cognitive, emotional and interpersonal), as well as the distinctions and similarities between humor and laughter. Further highlights of this interview include Professor Martin's comments on such diverse issues as the genetic versus environmental loadings for sense of humor, the multifaceted nature of the construct of humor, and the possible limitations of teaching individuals to use humor in a beneficial manner to cope with stress and enhance their social and

    Full Text Available Coincidence of autoimmune diseases such as immune thrombocytopenic purpura (ITP with  immunodeficiencies has  been  reported  previously in  patients  who  suffered  from primary antibody deficiency (PAD. But there is no original study on immunological profiles of ITP patients to find out their probable immune deficiency.In this case-control study, ITP patients’ humoral immunity was investigated for diagnosis of PAD in comparison with normal population. To evaluate the humoral immune system against polysaccharide antigens, patients’ serum immunoglobulin levels were measured and a 23-valent pneumococcal  capsular polysaccharide vaccine (PPV23 was administrated  to evaluate the antibody response to vaccination.In  this  study, 14 out  of  36 patients  (39% were diagnosed with antibody mediated immune deficiency including 2 patients (5.5% with immunoglobulin class deficiency and 4 (11% with IgG subclass deficiency. The remaining patients suffered from specific antibody deficiency. The most frequent deficiency in ITP patients was specific antibody deficiency.Therefore, immunological survey on ITP patients may be important especially for those who have undergone splenectomy.

  3. Aqueous extracts of the marine brown alga Lobophora variegata inhibit HIV-1 infection at the level of virus entry into cells.

    Directory of Open Access Journals (Sweden)

    Stephan Kremb

    Full Text Available In recent years, marine algae have emerged as a rich and promising source of molecules with potent activities against various human pathogens. The widely distributed brown alga Lobophora variegata that is often associated with tropical coral reefs exerts strong antibacterial and antiprotozoal effects, but so far has not been associated with specific anti-viral activities. This study investigated potential HIV-1 inhibitory activity of L. variegata collected from different geographical regions, using a cell-based full replication HIV-1 reporter assay. Aqueous L. variegata extracts showed strong inhibitory effects on several HIV-1 strains, including drug-resistant and primary HIV-1 isolates, and protected even primary cells (PBMC from HIV-1-infection. Anti-viral potency was related to ecological factors and showed clear differences depending on light exposition or epiphyte growth. Assays addressing early events of the HIV-1 replication cycle indicated that L. variegata extracts inhibited entry of HIV-1 into cells at a pre-fusion step possibly by impeding mobility of virus particles. Further characterization of the aqueous extract demonstrated that even high doses had only moderate effects on viability of cultured and primary cells (PBMCs. Imaging-based techniques revealed extract effects on the plasma membrane and actin filaments as well as induction of apoptosis at concentrations exceeding EC50 of anti-HIV-1 activity by more than 400 fold. In summary, we show for the first time that L. variegata extracts inhibit HIV-1 entry, thereby suggesting this alga as promising source for the development of novel HIV-1 inhibitors.

    In recent years, marine algae have emerged as a rich and promising source of molecules with potent activities against various human pathogens. The widely distributed brown alga Lobophora variegata that is often associated with tropical coral reefs exerts strong antibacterial and antiprotozoal effects, but so far has not been associated with specific anti-viral activities. This study investigated potential HIV-1 inhibitory activity of L. variegata collected from different geographical regions, using a cell-based full replication HIV-1 reporter assay. Aqueous L. variegata extracts showed strong inhibitory effects on several HIV-1 strains, including drug-resistant and primary HIV-1 isolates, and protected even primary cells (PBMC) from HIV-1-infection. Anti-viral potency was related to ecological factors and showed clear differences depending on light exposition or epiphyte growth. Assays addressing early events of the HIV-1 replication cycle indicated that L. variegata extracts inhibited entry of HIV-1 into cells at a pre-fusion step possibly by impeding mobility of virus particles. Further characterization of the aqueous extract demonstrated that even high doses had only moderate effects on viability of cultured and primary cells (PBMCs). Imaging-based techniques revealed extract effects on the plasma membrane and actin filaments as well as induction of apoptosis at concentrations exceeding EC50 of anti-HIV-1 activity by more than 400 fold. In summary, we show for the first time that L. variegata extracts inhibit HIV-1 entry, thereby suggesting this alga as promising source for the development of novel HIV-1 inhibitors.

  5. Adult Drosophila melanogaster evolved for antibacterial defense invest in infection-induced expression of both humoral and cellular immunity genes

    Full Text Available Abstract Background While the transcription of innate immunity genes in response to bacterial infection has been well-characterised in the Drosophila model, we recently demonstrated the capacity for such transcription to evolve in flies selected for improved antibacterial defense. Here we use this experimental system to examine how insects invest in constitutive versus infection-induced transcription of immunity genes. These two strategies carry with them different consequences with respect to energetic and pleiotropic costs and may be more or less effective in improving defense depending on whether the genes contribute to humoral or cellular aspects of immunity. Findings Contrary to expectation we show that selection preferentially increased the infection-induced expression of both cellular and humoral immunity genes. Given their functional roles, infection induced increases in expression were expected for the humoral genes, while increases in constitutive expression were expected for the cellular genes. We also report a restricted ability to improve transcription of immunity genes that is on the order of 2-3 fold regardless of total transcription level of the gene. Conclusions The evolved increases in infection-induced expression of the cellular genes may result from specific cross talk with humoral pathways or from generalised strategies for enhancing immunity gene transcription. A failure to see improvements in constitutive expression of the cellular genes suggests either that increases might come at too great a cost or that patterns of expression in adults are decoupled from the larval phase where increases would be most effective. The similarity in fold change increase across all immunity genes may suggest a shared mechanism for the evolution of increased transcription in small, discrete units such as duplication of cis-regulatory elements.

  6. Humor, desidealização e sublimação na psicanálise Humor, de-idealization and sublimation in psychoanalysis

    Full Text Available A motivação principal deste artigo é demonstrar que a metapsicologia do humor se oferece, na obra freudiana, como o paradigma a partir do qual se podem compreender as operações em jogo no processo da sublimação. Percebe-se, assim, que a associação entre duas problemáticas sombreadas pela tradição psicanalítica - o humor e a sublimação - contribui para o esclarecimento de ambas. Ao longo do texto são enfatizados o trabalho de desidealização promovido pelo humor, a modalidade identificatória envolvida na sua produção, a referência do humor negro à condição de orfandade que caracteriza o sujeito moderno, bem como a política que acompanha a anunciação do dito humorístico e, mesmo, do Witz (espirituosidade de modo geral. Finalmente, demonstra-se a filiação do humor ao realismo grotesco, amplamente analisado por Mikhail Bakhtin, indicando como, na enunciação humorística, é preciso considerar a participação da alegria, sua força motriz.This article's main motivation is to demonstrate that the metapsychology of humor offers itself, in the Freudian work, as a paradigm from which we can understand the operations at work in the process of sublimation. Thus, we can notice that the associations between two traditional psychoanalytical problems - humor and sublimation - contribute to its explanation. The text emphasizes the process of de-idealization through humor - as well as the aspect of identification involved in its production -, the reference of dark humor to the condition of "orphan" which characterizes the modern individual, and the politics that accompany the announcement of an amusing word (and even the Witz in general. Finally, it demonstrates the affinity of humor to grotesque realism, widely analyzed by Mikhail Bakhtin, showing how, in enunciating humor, it is necessary to consider the role of joy, its driving force.

  17. Sex differences in preferences for humor: a replication, modification, and extension.

    Science.gov (United States)

    Hone, Liana S E; Hurwitz, William; Lieberman, Debra

    2015-01-01

    Evolutionary-minded scientists have proposed that humor is a sexually selected trait in men that signals mate quality. Indeed, women tend to prefer men who make them laugh and men tend to prefer women who laugh at their jokes. However, it is unclear how robust this pattern is. Here we report a replication of one of the first studies (Bressler, Martin, and Balshine, 2006) to examine the sex differences in preferences for humor receptivity versus humor production. We replicate Bressler et al.'s (2006) findings that men prefer women who are receptive to their humor whereas women prefer men who produce humor. These findings held even after we modified Bressler et al.'s questionnaire for better conceptual validity. Furthermore, using a separate measure designed to assess trade-offs, we found that men viewed humor receptivity as a necessity and humor production as a luxury when they were asked to create an ideal long-term partner. For women, it was just the opposite. These results bolster the claim that sexual selection has shaped sex differences regarding preferences for a prospective mate's sense of humor and that what one means by "sense of humor" can vary.

  4. The Role of Humor in Learning Physics: a Study of Undergraduate Students

    2016-02-01

    We all know that they do it, but what do students laugh about when learning science together? Although research has shown that students do use humor when they learn science, the role of humor in science education has received little attention. In this study, undergraduate students' laughter during collaborative work in physics has been investigated. In order to do this, a framework inspired by conversation analysis has been used. Empirical data was drawn from two video-recorded sessions in which first-year engineering students solved physics problems together. The analysis revealed that the students' use of humor was almost exclusively related to physics. Five themes identified summarize the role of humor in the group discussions: Something is obvious, Something is difficult, Something said might be wrong, Something is absurd, and Something said is not within informal norms. This study shows that humor may contribute not only to a good working atmosphere and thereby to the students' learning but also how humor interrelates with both disciplinary culture of physics and its epistemology. The students do not only create and re-create humor that facilitates their social interactions, but through humor they constitute local norms of science and engage with the disciplinary discourse.

    Humor is everywhere in our daily life.It not only brings people laughter,but also reduces pressure,relaxes intensive atmosphere,and helps people avoid embarrassing situation.Meanwhile,humor can also reflect people’s attitude towards life and shows the charm of human being’s language and their wisdom.The problem is that humor cannot be accurately and vividly be translated due to varied factors such as culture,linguistics and spelling, etc. This thesis mainly analyzes the reasons and solutions of humor translation from the perspective of Skopos theory.This analysis is based on an abundance of humor examples.By such thorough analysis,it is found that differences in culture and linguistics account for the failures in humor translation.Chinese and westerners differ a lot in cultural vocabulary,conventional structure,semantic, syntax,social and historical background and value,which puts forth many problems for translation especially for humor translation that requires expressing the most vivid meaning in the least words.Under the guidance of Skopos theory,texts can also be successfully translated.It is under the guidance of Skopos theory no matter the translator adopts transliteration,domestication or method of notes.Therefore,by such analysis from the perspective of Skopos theory,readers will have a deep and thorough understanding of humor translation.

    2015-02-01

    Aquaculture production of Pacific red snapper Lutjanus peru is growing rapidly in Mexico, especially in Gulf of California. As it is a relatively new aquaculture species there are few reports evaluating its immune response to pathogens. The Gram-negative bacteria Aeromonas veronii is a heterogeneous organism that causes the disease known as motile aeromonad septicemia, which is responsible for serious economic loss in seabream culture due to bacterial infections. For the purpose of this study, juvenile Pacific red snapper specimens were intraperitoneally injected with low doses of A. veronii (1 × 10(6) CFU ml(-1)). Changes in humoral immune parameters (total protein, myeloperoxidase, lisozyme and antiprotease activities and IgM levels), as well as superoxide dismutase and catalase activities, and TLR9 gene expression were evaluated 24 and 48 h after injection. Overall, the results showed an enhanced in humoral immune parameters and SOD and CAT activities in fish infected with A. veronii compared with control group at 24 or 48 h. By real time PCR assays, the basal mRNA transcripts of TLR9 showed that were highly expressed in intestine and leucocytes compared to skin, head kidney, liver and gill. Then, the mRNA expression levels of TLR9 in head kidney, skin, liver and intestine were analyzed in non-infected and experimentally infected fish 24 and 48 h after injection. A. veronii up-regulated the expression of TLR9 at 24 or 48 h of exposure in all samples analyzed except in liver. Interestingly, intestine produced the greatest increase in transcript levels upon exposure (48 h) to A. veronii. Taken together, our results suggest that low doses of A. veronii infection inducing humoral immune system and TLR9 immune gene in Pacific red snapper that can be useful in the health control of this species.

    Full Text Available The present study examined the effectiveness of a humor therapy program in relieving chronic pain, enhancing happiness and life satisfaction, and reducing loneliness among older persons with chronic pain. It was a quasiexperimental pretest-posttest controlled design. Older persons in a nursing home were invited to join an 8-week humor therapy program (experimental group, while those in another nursing home were treated as a control group and were not offered the program. There were 36 older people in the experimental group and 34 in the control group. Upon completion of the humor therapy program, there were significant decreases in pain and perception of loneliness, and significant increases in happiness and life satisfaction for the experimental group, but not for the control group. The use of humor therapy appears to be an effective nonpharmacological intervention. Nurses and other healthcare professionals could incorporate humor in caring for their patients.

Finally, the antigenicity of these PUF proteins was evaluated by determining levels of specific antibodies in sera from experimentally infected hamsters. The Leishmania PUFs were all recognized by the sera, even though with different degree of reactivity and/or frequency of recognition. The reactivity of hamster sera against recombinant LiPUF1 and LiPUF2 was particularly prominent, and these proteins were subsequently assayed against sera from human patients. High antibody responses against rLiPUF1 and rLiPUF2 were found in sera from VL patients, but these proteins resulted also recognized by sera from Chagas' disease patients. Conclusion Our results suggest that Leishmania PUFs are targets of the humoral response during L. infantum infection and may represent candidates for serodiagnosis and/or vaccine reagents; however, it should be kept in mind the cross-reactivity of LiPUFs with antibodies induced against other trypanosomatids such as Trypanosoma cruzi.

    Full Text Available Introduction: Among several tuberculosis vaccine candidates for replacement of BCG, ESAT-6 protein has a special role. Since mycobacterium tuberculosis infection most often attacks the lungs, intranasal rout can be regarded as appropriate methods for tuberculosis vaccines and drug delivery. One of the appropriate systems for intranasal vaccine delivery is using biodegradable nanoparticles. Among biodegradable polymers, chitosan polymer has great features to increase the response of immunity system. This study aimed to investigate the specific humoral immune response of mice model after encapsulation of recombinant ESAT-6 antigen in chitosan nanoparticles. Methods: The chitosan nanoparticles containing ESAT-6 antigen were synthesized by ionic gelation. Nanoparticle properties including morphology, particle size, zeta potential, encapsulation rates, and protein release were measured in vitro. The immunization was performed through the nose for 3 times on days 0 and 14 and 28. 2 weeks after last administration, blood samples were collected and specific IgG titers were measured by indirect ELISA. Results: The nanoparticles synthesized had appropriate properties. The mean size of resulting nanoparticles was 242.8 nm by excellent antigen loading capacity (95.23 %. The vitro release of antigen from nanoparticles after 200 hours was detected as 67.5%. The Level of IgG antibody showed significant increase in the group that had received chitosan nanoparticles containing ESAT-6 compared with other groups. Conclusion: ESAT-6 protein was encapsulated in chitosan nanoparticles successfully. Administration of chitosan nanoparticles can be a suitable method for administration of humoral immunity antigens of Mycobacterium tuberculosis through intranasal rout.

    To develop a safe and novel immunoadjuvant to enhance the immunity and resistance of animals against E.coli infection. Methods An 88-base immunostimulatory oligodeoxynuleotide containing eleven CpG motifs (CpG ODN)was synthesized and amplified by PCR. The chitosan nanoparticle (CNP) was prepared by ion linking method to entrap the CpG ODN that significantly promotes the proliferation of lymphocytes of pig in vitro. Then the CpG- CNP was inoculated into 21-day old Kunming mice, which were orally challenged with virulent K88/K99 E. Coli 35 days after inoculation. Blood was collected from the tail vein of mice on days 0, 7, 14, 21, 28, 35, 42, and 49 after inoculation to detect the changes and content of immunoglobulins, cytokines and immune cells by ELISA, such as IgG, IgA, IgM, IL-2, IL-4, and IL-6. Results The CpG provoked remarkable proliferation of lymphocytes of pig in vitro in comparison with that of control group (P<0.05). The inoculation with CpG-CNP significantly raised the content of IgG, IgM, and IgA in the sera of immunized mice (P<0.05). The levels of IL-2, IL-4, and IL-6 in the mice significantly increased in comparison with those in controls (P<0.05), so was the number of white blood cells and lymphocytes in immunized mice. The humoral and cellular immunities were significantly enhanced in immunized mice, which resisted the infection of E. coli and survived, while the control mice manifested evident symptoms and lesions of infection. Conclusions CpG-CNP can significantly promote cellular and humoral immunity and resistance of mice against E. coli infection, and can be utilized as an effective adjuvant to improve the immunoprotection and resistance of porcine against infectious disease.

    Full Text Available BACKGROUND: Humoral immune responses in human immunodeficiency virus (HIV-infected and uninfected children with Pneumocystis pneumonia (PcP are poorly understood. METHODS: Consecutive children hospitalized with acute pneumonia, tachypnea, and hypoxia in South Africa were investigated for PcP, which was diagnosed by real-time polymerase chain reaction on lower respiratory tract specimens. Serum antibody responses to recombinant fragments of the carboxyl terminus of Pneumocystis jirovecii major surface glycoprotein (MsgC were analyzed. RESULTS: 149 children were enrolled of whom 96 (64% were HIV-infected. PcP occurred in 69 (72% of HIV-infected and 14 (26% of HIV-uninfected children. HIV-infected children with PcP had significantly decreased IgG antibodies to MsgC compared to HIV-infected patients without PcP, but had similar IgM antibodies. In contrast, HIV-uninfected children with PcP showed no change in IgG antibodies to MsgC, but had significantly increased IgM antibodies compared to HIV-uninfected children without PCP. Age was an independent predictor of high IgG antibodies, whereas PcP was a predictor of low IgG antibodies and high IgM antibodies. IgG and IgM antibody levels to the most closely related MsgC fragments were predictors of survival from PcP. CONCLUSIONS: Young HIV-infected children with PcP have significantly impaired humoral immune responses to MsgC, whereas HIV-uninfected children with PcP can develop active humoral immune responses. The children also exhibit a complex relationship between specific host factors and antibody levels to MsgC fragments that may be related to survival from PcP.

    Full Text Available This article discusses the representation of the image of teachers in the novel entitled Mlantjaran ka Sasak written by Gde Srawana. Using the theory of literary sociology and the theory of representation as the basis of analysis, it was found that teachers were  imaged of being dilemmatic, humanistic idealistic, caring about the Balinese culture, and being humorous. Sociologically, the novel entitled Mlantjaran ka Sasak pictured the life background of the Balinese society during 1930s, indicated by the critical attitude of the intellectuals through I Made Sarati and Ida Ayu Priya, the characters who played a role as teachers, towards the caste feudalism in marriage. Such a critical attitude was expressed in such an inciting way that the ethic and aesthetic values needed to educate society were not neglected.

    Immunoglobulins cannot cross the placenta in pregnant sows. Neonatal pigs are therefore agammaglobulinemic at birth and, although immunocompetent, they cannot mount rapid immune responses at systemic and mucosal sites. Their survival depends directly on the acquisition of maternal immunity via colostrum and milk. Protection by maternal immunity is mediated by a number of factors, including specific systemic humoral immunity, involving mostly maternal IgG transferred from blood to colostrum and typically absorbed within the first 36 h of life. Passive mucosal immunity involves local humoral immunity, including the production of secretory IgA (sIgA), which is transferred principally via milk until weaning. The mammary gland (MG) produces sIgA, which is, then secreted into the milk via the poly-Ig receptor (pIgR) of epithelial cells. These antibodies are produced in response to intestinal and respiratory antigens, including pathogens and commensal organisms. Protection is also mediated by cellular immunity, which is transferred via maternal cells present in mammary secretions. The mechanisms underlying the various immunological links between MG and the mucosal surfaces involve hormonally regulated addressins and chemokines specific to these compartments. The enhancement of colostrogenic immunity depends on the stimulation of systemic immunity, whereas the enhancement of lactogenic immunity depends on appropriate stimulation at induction sites, an increase in cell trafficking from the gut and upper respiratory tract to the MG and, possibly, enhanced immunoglobulin production at the effector site and secretion in milk. In addition, mammary secretions provide factors other than immunoglobulins that protect the neonate and regulate the development of mucosal immunity--a key element of postnatal adaptation to environmental antigens.

  7. Natural and Induced Humoral Responses to MUC1

    International Nuclear Information System (INIS)

    MUC1 is a membrane-tethered mucin expressed on the ductal cell surface of glandular epithelial cells. Loss of polarization, overexpression and aberrant glycosylation of MUC1 in mucosal inflammation and in adenocarcinomas induces humoral immune responses to the mucin. MUC1 IgG responses have been associated with a benefit in survival in patients with breast, lung, pancreatic, ovarian and gastric carcinomas. Antibodies bound to the mucin may curb tumor progression by restoring cell-cell interactions altered by tumor-associated MUC1, thus preventing metastatic dissemination, as well as counteracting the immune suppression exerted by the molecule. Furthermore, anti-MUC1 antibodies are capable of effecting tumor cell killing by antibody-dependent cell-mediated cytotoxicity. Although cytotoxic T cells are indispensable to achieve anti-tumor responses in advanced disease, abs to tumor-associated antigens are ideally suited to address minimal residual disease and may be sufficient to exert adequate immune surveillance in an adjuvant setting, destroying tumor cells as they arise or maintaining occult disease in an equilibrium state. Initial evaluation of MUC1 peptide/glycopeptide mono and polyvalent vaccines has shown them to be immunogenic and safe; anti-tumor responses are scarce. Progress in carbohydrate synthesis has yielded a number of sophisticated substrates that include MUC1 glycopeptide epitopes that are at present in preclinical testing. Adjuvant vaccination with MUC1 glycopeptide polyvalent vaccines that induce strong humoral responses may prevent recurrence of disease in patients with early stage carcinomas. Furthermore, prophylactic immunotherapy targeting MUC1 may be a strategy to strengthen immune surveillance and prevent disease in subjects at hereditary high risk of breast, ovarian and colon cancer

    Full Text Available This quantitative study examines the correlations between humor, loneliness, gender and aging by presenting the results from a sample of eighty-three older Romanian adults, aged sixty and above. The first section of the paper is a comprehensive review of the social-psychological literature on aging, gender and humor. The second section assesses the findings generated from a study that uses the Multidimensional Sense of Humor Scale (Thorson & Powell, 1993 and the Social and Emotional Loneliness Scale for Adults – short version, (diTomaso, Brannen & Best, 2004. Building on Robert Weiss’s (1973 reflections on the differences between feelings of loneliness because of social isolation or emotional isolation, the research findings nuance –and in some cases challenge several assumptions on gender, age, and emotional and social loneliness. The findings also point to the correlation between feelings of social loneliness and the use of humor in interpersonal communications. The data collected suggests that while Romanian men may value the use of humor more than women when self-reporting, that older Romanian women tend to use humor in interpersonal situations and that there is a significant correlation between the use of this type of humor and a reduced sense of social loneliness.

    Infancy is a critical time for the development of secure attachment, which is facilitated by emotionally synchronous interactions with parents. Humor development, which includes shared laughter and joint attention to an event, emerges concurrently with attachment, but little is known regarding the relationship, if any, between humor development and attachment in the first year. Thirty 3-month-old infants were videoed at home each month until they were 6-months old while their parents attempted to amuse them. Frequency of infants' smiles and laughs served as a measure of "state humor", and the smiling/laughing subscale of the Infant Behavior Questionnaire-Revised served as a measure of "trait humor". State and trait humor were not correlated. Lower trait humor as 6 months predicted higher attachment security on the Attachment Q-sort at 12-months (r=.46), suggesting that less good-humored infants elicit greater parental engagement, which works to the benefit of attachment, or vice versa. Future studies should examine the importance of smiling and laughter as they relate to other developmental phenomena in the first year. PMID:22982281

    has to conform to in order to reach a Danish audience. Although humour in general has many faces the humorous style in Danish TV-ads is typically one of good will and seldom one of offensiveness. The intention is to include and create common ground in a playful way. In contrast the concept of lifestyle is basically a way of construing and segmenting audiences that prescribes exclusion and distinction or at least underlines barriers and differences between groups of people, their values and mentalities and accordingly also manifests these differences in the mode of address and the style of execution. The point the article makes is that humour in several respects represents a pragmatic way, making it possible to by-pass or transcend some of the problems raised by segmentation, lifestyle and unique brands - especially in a relatively small (Danish market. The ambiguous mode of humour displaces the facts and the reality referred to by lifting things up to another (playful level and/or by staging them via more or less grotesque events and non-realistic characters and universes. The displacement makes up a common, ’neutral’ ground and a marked level of incongruence in which it is possible to cross borders of lifestyle as well as other borders and problems inherent in marketing communication and consequently appeal in a broader and more inclusive way.

    Full Text Available Over the last years there has been a growing interest in the study of the resources that people use from face to a problem. The interest in the study of the characteristics related to the humor has gone in increase, especially for the influence of the development of a new concept in psychology that derives in the call positive psychology (Seligman and Csikszentmihalyi, 2000; Zinder and McCullog 2000, in Martin, Puhlik-Doris, Larsen, Gray, Weir, 2003 which is centered in adaptive strengths such as optimism, faith, courage, as well as humor (Martin 2003, quoted in Martin et al., 2003. Sense of humor has been considered as an unidimensional construct (Omar, 1995 and the consequencies has been some errors in the assesment, as a result of a problem of validity. The present study seeks to introduce certain aspects that have not been considered in the past, so much the potential beneficial effects, as the deleterious forms of the sense of humor as for the psychological well-being. Four dimensions of the sense of humor were assesed (Martin, Puhlik-Doris, Larsen, Gray, Weir, 2003, version Lillo, 2006 relating to the uses or functions in everyday life and the ways of people cope (Fridenberg and Lewis, 1991, version Richaud de Minzi. 2003. They were also significant relationships among styles of humor and ways of coping that could explain the importance of the construct sense of humor, as an important resource to be used. Although it is necessary to highlight that it is not sought to embrace all the components of the sense of humor, but rather it is focused in the interpersonal functions and intrapsíquicas that adolescents use in daily life. These functions are considered most relevant to the well-being. Measuring these aspects of the humor, it is expected that they can explain a greater proportion of the variance as for the ways of people cope. 

  13. Isocitrate dehydrogenase of Helicobacter pylori potentially induces humoral immune response in subjects with peptic ulcer disease and gastritis.

    M Abid Hussain

    Full Text Available BACKGROUND: H. pylori causes gastritis and peptic ulcers and is a risk factor for the development of gastric carcinoma. Many of the proteins such as urease, porins, flagellins and toxins such as lipo-polysaccharides have been identified as potential virulence factors which induce proinflammatory reaction. We report immunogenic potentials of isocitrate dehydrogenase (ICD, an important house keeping protein of H. pylori. METHODOLOGY/PRINCIPAL FINDINGS: Amino acid sequences of H. pylori ICD were subjected to in silico analysis for regions with predictably high antigenic indexes. Also, computational modelling of the H. pylori ICD as juxtaposed to the E. coli ICD was carried out to determine levels of structure similarity and the availability of surface exposed motifs, if any. The icd gene was cloned, expressed and purified to a very high homogeneity. Humoral response directed against H. pylori ICD was detected through an enzyme linked immunosorbent assay (ELISA in 82 human subjects comprising of 58 patients with H. pylori associated gastritis or ulcer disease and 24 asymptomatic healthy controls. The H. pylori ICD elicited potentially high humoral immune response and revealed high antibody titers in sera corresponding to endoscopically-confirmed gastritis and ulcer disease subjects. However, urea-breath-test negative healthy control samples and asymptomatic control samples did not reveal any detectable immune responses. The ELISA for proinflammatory cytokine IL-8 did not exhibit any significant proinflammatory activity of ICD. CONCLUSIONS/SIGNIFICANCE: ICD of H. pylori is an immunogen which interacts with the host immune system subsequent to a possible autolytic-release and thereby significantly elicits humoral responses in individuals with invasive H. pylori infection. However, ICD could not significantly stimulate IL8 induction in a cultured macrophage cell line (THP1 and therefore, may not be a notable proinflammatory agent.

    The present study was undertaken to explore the effect of the essential oil isolated from the buds of Eugenia caryophyllata on some immunological parameters. Humoral immunity was assessed by measuring the hemagglutination titre to sheep red blood cells and delayed type hypersensitivity was assessed by measuring foot pad thickness. Clove oil administration produced a significant increase in the primary as well as secondary humoral immune response. In addition, it also produced a significant decrease in foot pad thickness compared with the control group. Thus, these results suggest that clove oil can modulate the immune response by augmenting humoral immunity and decreasing cell mediated immunity. PMID:21796701

    Dimethyl sulfate (DMS) is an alkylating reagent commonly used in organic syntheses and pharmaceutical manufacturing processes. Due to its potential carcinogenicity, the level of DMS in the API process needs to be carefully monitored. However, in-process testing for DMS is challenging because of its reactivity and polarity as well as complex matrix effects. In this short communication, we report a GC-MS method for determination of DMS in an API intermediate that is a methyl sulfate salt. To overcome the complex matrix interference, DMS and an internal standard, d6-DMS, were extracted from the matrix with methyl tert-butyl ether. GC separation was conducted on a DB-624 column (30 m long, 0.32 mm ID, 1.8 microm film thickness). MS detection was performed on a single-quad Agilent MSD equipped with an electron impact source while the MSD signal was acquired in selected ion monitoring mode. This GC/MS method showed a linear response for DMS equivalent from 1.0 to 60 ppm. The practical quantitation limit for DMS was 1.0 ppm and the practical detection limit was 0.3 ppm. The relative standard derivation for analyte response was found as 0.1% for six injections of a working standard equivalent to 18.6 ppm of DMS. The spike recovery was ranged from 102.1 to 108.5% for a sample of API intermediate spiked with 8.0 ppm of DMS. In summary, the GC/MS method showed adequate specificity, linearity, sensitivity, repeatability and accuracy for determination of DMS in the API intermediate. This method has been successfully applied to study the efficiency of removing DMS from the process. PMID:19576712

Fish were divided into 5 groups repeated in triplicates and each group were fed on experimental diets for 7 weeks. Growth performance parameters, skin mucus total immunoglobulin (Ig) level, lysozyme, protease and alkaline phosphatase (ALP) activity as well as the non-specific humoral immune response (total Ig, lysozyme, alternative haemolytic complement activity (ACH50) were determined at the end of feeding trial. The results showed that supplementation of diet with 0.25% SP significantly improved growth performance compared control group (P skin mucus immune parameters revealed significant elevation in fish fed SP supplemented diet (P  0.05), except 0.25% SP treatment which was significantly higher than those in other groups (P < 0.05). These results revealed that inclusion of administration of 0.25% and 0.5% SP in early stage of the Caspian white fish culture could improve mucosal and non-specific immune responses as well as performance.

    Full Text Available Rubinstein-Taybi syndrome (RTS is a rare developmental disorder characterized by craniofacial dysmorphisms, broad thumbs and toes, mental and growth deficiency, and recurrent respiratory infections. RTS has been associated with CREBBP gene mutations, but EP300 gene mutations have recently been reported in 6 individuals. In the present study, the humoral immune response in 16 RTS patients with recurrent respiratory infections of possible bacterial etiology was evaluated. No significant differences between patients and 16 healthy controls were detected to explain the high susceptibility to respiratory infections: normal or elevated serum immunoglobulin levels, normal salivary IgA levels, and a good antibody response to both polysaccharide and protein antigens were observed. However, most patients presented high serum IgM levels, a high number of total B cell and B subsets, and also high percentiles of apoptosis, suggesting that they could present B dysregulation. The CREBBP/p300 family gene is extremely important for B-cell regulation, and RTS may represent an interesting human model for studying the molecular mechanisms involved in B-cell development.

    This scoping study examines the relation of the sense of humor and three dispositions toward ridicule and being laughed at to psychopathic personality traits. Based on self-reports from 233 adults, psychopathic personality traits were robustly related to enjoying laughing at others, which most strongly related to a manipulative/impulsive lifestyle and callousness. Higher psychopathic traits correlated with bad mood and it existed independently from the ability of laughing at oneself. While overall psychopathic personality traits existed independently from the sense of humor, the facet of superficial charm yielded a robust positive relation. Higher joy in being laughed at also correlated with higher expressions in superficial charm and grandiosity while fearing to be laughed at went along with higher expressions in a manipulative life-style. Thus, the psychopathic personality trait could be well described in its relation to humor and laughter. Implications of the findings are highlighted and discussed with respect to the current literature. PMID:22559907

We review emotional eating, obesity, and the hypothesized mechanisms of emotional eating. We then review the field of therapeutic humor and its ability to de-stress individuals, possibly through endorphin and opioid systems, both of which are also involved in eating behavior. Finally, we present a novel hypothesis that people may be trained to use humor as a “food substitute” at best, or to blunt hunger stimuli, to achieve similar advantages, without the side effect of weight gain.

Para plantear si “el enseñar contento y el aprender con alegría” pueden aumentar la eficacia en el proceso de enseñanza-aprendizaje, se abordará cómo, a pesar de las múltiples ventajas que puede aportar el humor en las aulas, se omite su empleo por la existencia de ciertos prejuicios y temores. La idea no es que los docentes hagan el papel de comediantes o payasos, sino la de mediar y acercar la clase de manera pedagógica y didáctica a través del uso del humor, y sobre esto reflexionaba Platón (1992, cuando planteaba que muchas veces ayudaba una broma, en donde la seriedad oponía resistencia. Abstract. This paper studies the importance of humor as a teaching strategy in the classroom, considering the usual lack of motivation and boredom. To analyze whether the “happy teaching and happy learning” may increase effectiveness in the teaching-learning process, the author will discuss how, despite the many benefits it may bring, humor is not used in the classroom due to prejudices and fears. The idea is not for teachers to play the role of a comedian or a clown, but to intervene and get closer to the group with a teaching, didactic purpose through humor. Plato (1992 thought about this; he used to say that sometimes a joke may help, where seriousness put up resistance.

    The cardioprotection afforded by remote ischaemic conditioning (RIC) is mediated via a complex mechanism involving sensory afferent nerves, the vagus nerve, and release of a humoral blood-borne factor. However, it is unknown whether release of the protective factor depends on vagal activation or occurs independently. This study aimed to evaluate the co-dependence of the neural and humoral pathways of RIC, focussing on the vagus nerve and intrinsic cardiac ganglia. In the first study, anesthet...

    Humour research is often about verbal humour. Language allows us to play with words and with its syntactic, semantic and pragmatic aspects. It provides us with building blocks that can be composed in unusual ways, introducing ambiguities, confusion, inappropriate language use, and incongruities. This allows the design of humour, whether it is word play, verbal jokes, or humorous remarks triggered by conversational interaction. Design and analysis of verbal humor has become part of computation...

    The nurse scholar, whether a supervisor, an educator, or a practitioner, has a lifetime of research opportunities as well as personal experiences related to the human need for humor. We need to develop the means to assess the individual's and group's response to humor. Nurse scholars, particularly the nurse supervisor, can make a significant contribution in the search to harness some of the energy we use in laughing and direct it toward helping us heal our human conditions.

    Bovine mastitis produces economic losses, attributable to the decrease in milk production, reduced milk quality, costs of treatment and replacement of animals. A successful prophylactic vaccine against Staphylococcus aureus should elicit both humoral and cellular immune responses. In a previous report we evaluated the effectiveness of a live vaccine to protect heifers against challenge with a virulent strain. In the present study the immunological response of heifers after combined immunization schedule was investigated. In a first experimental trial, heifers were vaccinated with 3 subcutaneous doses of avirulent mutant S. aureus RC122 before calving and one intramammary dose (IMD) after calving. Antibodies concentration in blood, bactericidal effect of serum from vaccinated animals and lymphocyte proliferation was determined. The levels of total IgG, IgG1 and IgG2 in colostrum and the lymphocyte proliferation index were significantly higher in vaccinated respect to non-vaccinated group throughout the experiment. The second trial, where animals were inoculated with different vaccination schedules, was carried out to determine the effect of the IMD on the level of antibodies in blood and milk, cytokines (IL-13 and IFN-γ) concentration and milk's SCC and bacteriology. The bacterial growth of the S. aureus strains was totally inhibited at 1-3×10(6) and 1-3×10(3)cfu/ml, when the strains were mixed with pooled serum diluted 1/40. The results shown that IMD has not a significant effect on the features determinate. In conclusion, a vaccination schedule involving three SC doses before calving would be enough to stimulate antibodies production in milk without an IMD. Furthermore, the results showed a bactericidal effect of serum from vaccinated animals and this provides further evidence about serum functionality. Immune responses, humoral (antigen-specific antibodies and Th2 type cytokines) and cellular (T-lymphocyte proliferation responses and Th1 type cytokines), were

    While the antigenic specificity and pathogenic relevance of immunologic reactivity to gluten in celiac disease have been extensively researched, the immune response to nongluten proteins of wheat has not been characterized. We aimed to investigate the level and molecular specificity of antibody response to wheat nongluten proteins in celiac disease. Serum samples from patients and controls were screened for IgG and IgA antibody reactivity to a nongluten protein extract from the wheat cultivar Triticum aestivum Butte 86. Antibodies were further analyzed for reactivity to specific nongluten proteins by two-dimensional gel electrophoresis and immunoblotting. Immunoreactive molecules were identified by tandem mass spectrometry. Compared with healthy controls, patients exhibited significantly higher levels of antibody reactivity to nongluten proteins. The main immunoreactive nongluten antibody target proteins were identified as serpins, purinins, α-amylase/protease inhibitors, globulins, and farinins. Assessment of reactivity toward purified recombinant proteins further confirmed the presence of antibody response to specific antigens. The results demonstrate that, in addition to the well-recognized immune reaction to gluten, celiac disease is associated with a robust humoral response directed at a specific subset of the nongluten proteins of wheat.

    The concentrations of swine epithelial antigen (SEA), swine urinary antigen (SUA) and swine feed antigen (SFA) were measured in swineries. SEA seems to be the most prevalent of the constituents measured. In the serum samples of the subjects studied, specific IgG antibodies against the antigens were frequently encountered. However, a difference was seen in the distribution of anti-SUA-IgG antibodies between swinery workers and a control group of students. The influence of the level of specific dust concentrations on specific antibody titers was studied statistically. Positive correlations were observed between stationary site SUA concentrations and anti-SUA-IgG and anti-SEA-IgG titers, respectively, pointing to an association between exposure and humoral response in swinery work. Consequently, our results suggest that the measurement of antibodies against SUA or its components could offer a basis for the estimation of the level of swinery work-related respiratory exposure and for monitoring the quality of the working environment in swineries.

    Full Text Available Abstract Background The application of high throughput molecular techniques such as SEREX are resulting in the identification of a multitude of tumor associated antigens. As newly identified antigens are incorporated into a variety of clinical trials, standardization of immunologic monitoring methods becomes increasingly important. We questioned whether mammalian cell expression of a histadine-linked human protein could be used to produce antigen suitable for detecting tumor-specific humoral immunity and whether such an assay could be amenable to standardization for clinical use. Methods We designed a his-tagged capture ELISA based on lysate from genetically engineered CHO cells for detection of antibodies to insulin-like growth factor binding protein 2, a novel tumor antigen. We performed technical and preliminary clinical validation studies, including comparison to a standard indirect ELISA based on commercially prepared recombinant antigen. Results The his-tagged capture ELISA could be standardized. Precision experiments resulted in CVs 2 values of 0.99. In comparison to Western blot analysis, his-tag and indirect ELISA accurately identified 88% and 93% of samples, respectively. Sample concordance between capture and indirect assays was highly significant (p = 0.003. Furthermore, significantly greater levels of IGFBP-2 antibody immunity were found in cancer patients compared to normal controls (p = 0.008. Conclusion A genetically engineered cell lysate based ELISA can be amenable to standardization and can detect increased levels of antibody immunity to tumor-associated antigen in cancer patients compared to non tumor-bearing healthy controls.

    Dark humor is defined as a stylistic feature with irony at its core. The weapon for the powerless, dark humor always targets those in power. In Sula, Toni Morrison employs irony to satirize African American stereotypes established by racism and sexism. To survive, African Americans ann themselves with humor. Humor implies hope. The (dark) humor in Sula brings spiritual comfort to the victims of racism and sexism, strengthens the Bottom, the black community, challenges the grand narrative of the U.S. history, and proves an essential component of American humor.%黑色幽默是一种文体,反讽是其常用的技巧。黑色幽默是草根的武器,权势是黑色幽默的靶子。在《秀拉》中,莫里森采用反讽,嘲讽种族主义者设定的美国黑人刻板形象,条分缕析地抨击种族歧视和性别歧视。哪里有幽默,哪里就有希望。幽默不但令黑人取得了精神上的胜利,而且挑战美国官方历史的宏大叙事,更为美国幽默增添了多元视角。

  15. Long-term exposure to arsenic affects head kidney and impairs humoral immune responses of Clarias batrachus

    International Nuclear Information System (INIS)

    The present study was aimed at determining the effects of long-term arsenic exposure on the head kidney (HK) and ensuing humoral immune responses in Clarias batrachus L. Long-term exposure (150 days) to non-lethal concentrations of arsenic (42.42 μM) resulted in significant time-dependent alterations in HK cell number eventually affecting the HK somatic index. Prolonged exposure to arsenic also suppressed HK-B cell proliferation and led to significant reduction in serum immunoglobulin levels and antigen-specific serum bacterial agglutinin titers. A decline in the number of antigen-specific plaque-forming cells with duration of arsenic exposure was noted in the HK. Enzyme linked immunosorbent assays further revealed that arsenic exposure inhibited the release of 'IL-4 like factors' from HK-T cells. Histological studies documented time-dependent changes in the structure and cellular composition of HK characterized by extensive lymphocytopenia, decrease in melano-macrophage population and hemosiderin accumulation. From exposure-challenge studies with Aeromonas hydrophila it was evident that pathogens could efficiently disseminate and colonize distant host tissues in the exposed fish. Moreover, the ability to decrease the pathogen load was also significantly reduced in the arsenic-exposed fish. Thus long-term exposure to non-lethal concentrations of arsenic affects HK and interferes with the humoral immune system of C. batrachus rendering them immunocompromised and susceptible to pathogenic challenge

    Drones are haploid male individuals whose major social function in honey bee colonies is to produce sperm and mate with a queen. In spite of their limited tasks, the vitality of drones is of utmost importance for the next generation. The immune competence of drones - as compared to worker bees - is largely unexplored. Hence, we studied humoral and cellular immune reactions of in vitro reared drone larvae and adult drones of different age upon artificial bacterial infection. Haemolymph samples were collected after aseptic and septic injury and subsequently employed for (1) the identification of immune-responsive peptides and/or proteins by qualitative proteomic analyses in combination with mass spectrometry and (2) the detection of antimicrobial activity by inhibition-zone assays. Drone larvae and adult drones responded with a strong humoral immune reaction upon bacterial challenge, as validated by the expression of small antimicrobial peptides. Young adult drones exhibited a broader spectrum of defence reactions than drone larvae. Distinct polypeptides including peptidoglycan recognition protein-S2 and lysozyme 2 were upregulated in immunized adult drones. Moreover, a pronounced nodulation reaction was observed in young drones upon bacterial challenge. Prophenoloxidase zymogen is present at an almost constant level in non-infected adult drones throughout the entire lifespan. All observed immune reactions in drones were expressed in the absence of significant amounts of vitellogenin. We conclude that drones - like worker bees - have the potential to activate multiple elements of the innate immune response. PMID:22442369

    Full Text Available Abstract Grotesque is a concept and style in art and literature in which artist or belletrist tries to induce two inconsistent senses of fear (anxiety or repulsion or laugh (satire or humor to second person simultaneously. Grotesque, today, describes and manifests distressed and alienation world. It means observing familiar world of strange perspective that shows off it fearful and ridiculous. The most prominent features that make a Grotesque work are as fallow: disharmony, extravagance and exaggeration, abnormality and comic and terrifying. But one of the most important art and literature branches that Grotesque enters in it, is satire and humor that one of its kind is Caricalamatur.   Caricalamatur is a kind of short, simple and satire prose that paid attention to around to phenomenon and world by different attitude with aim of foregrounding and based on some people opinion, also, it is defined as a caricature that is expressed by worlds.   Grotesque in Caricalamaturs has special appearance particularly in Caricalamatur of Parviz e Shapoor, the pioneer of this style.Grotesque in Caricalamaturs is more the result of two technics of abnormality (paradox, and extravagance and exaggeration and present to it strange and comic and terrifying picture quality.   The most important of Grotesque technics in Caricalamaturs are disorder, levels integration, exaggeration, movement, metamorphosis and uses of antithetical and twin.This research has performed by descriptive- analytical method to recognize and investigate Grotesque concepts, how it occurs and its contents in Caricalamatur by evidence representation.

  19. Effects of splenectomy on the humoral immune system

    International Nuclear Information System (INIS)

    Experiments were performed to investigate the influence of neonatal and adult splenectomy on humoral immunity in mice. In the bone marrow and lymph nodes of both groups of splenectomized mice the number of immunoglobulin (Ig)-positive (B) lymphocytes was significantly higher than in sham-operated mice. These higher numbers of B cells probably reflect a compensation for the absence of the B cell population of the spleen. Hardly any quantitative differences in the serum immunoglobulins were found between splenectomized and sham-splenectomized mice. Only for the IgM class was a significantly lower concentration found in the serum of splenectomized animals. This low concentration of IgM in the blood of splenectomized mice was caused by a failure of the remaining organs to compensate completely for the removal of the quantitatively important population of IgM-producing plasma cells in the spleen. Nevertheless, the number of precursors of IgM-producing plasma cells in bone marrow and lymph nodes and their ability to differentiate into IgM-producing plasma cells was not diminished by splenectomy. Probably the spleen provides a highly efficient environment for the differentiation into IgM-producing plasma cells. By investigating the synergistic ability of bone marrow cells and thymus cells from neonatally splenectomized mice it was found that these cells were fully capable of co-operating in the adoptive plaque-forming cell response to sheep red blood cells (SFBC).

    Full Text Available A partir de la afirmación de S. Critchley de que el psicoanálisis es la prolongación, profundización y complicación de lo que él llama paradigma trágico-heroico, se trata de precisar que lo trágico es lo que hace inseparables la teoría y la experiencia psicoanalítica de la risa y los fenómenos ligados a ella. Esto, en general, ha sido insuficientemente indagado. Siguiendo estos argumentos, se presentan algunas observaciones en torno a esa especie de exhortación “volver a las cosas mismas”, tan afín al método freudiano, al “uso” de lo trágico-heroico en Lacan, al concepto de Cosa y al aporte de Freud al humor. Por otra parte, y en completa relación con lo anterior, se destacan algunos señalamientos lacanianos que ubican al “cuerpo” como central en la experiencia de lo cómico. Y por último, se examina la contraposición Bergson - Freud - Lacan en torno a la risa, lo mecánico y el lenguaje.

    The term “scrofula” was used for a long time to designate a chronic swelling of cervical lymph nodes. This paper outlines the prevalent ideas on the nature, pathogenesis and the treatment of this disorder, from classical Greek medicine up to the 18th century. A Hippocratic treatise regarded scrofula as produced by an accumulation of phlegm, with a consequent imbalance or dyscrasia of the body humors. It was believed that it could heal spontaneously; but it could also soften, open through the skin and have an obstinate course. The treatment consisted mainly on local applications, incision to evacuate the soft content, or extirpation of the abnormal mass. In France and England, crowds of scrofulous patients were touched by the kings who were supposed to have a hereditary miraculous power to cure the disease. A Medieval text mentioned that scrofula could also affect other parts of the body. In the 17th century, scrofula was reputed as a frequent condition and was attributed to blood acrimony which coagulated in spongy organs. It was associated to phthisis or consumption due to the lethal outcome in some patients and to a cheese-like appearance of the pulmonary and the scrofulous lesions. PMID:27401383

    Full Text Available Abstract. Age dynamics of humoral immunity was studied in healthy children, i.e., 11 newborns, 33 infants of 4 to 8 months, 32 children of 1 to 2 years old,, 17 children of 4 to 5 years old, 25 children of 6 to 8 years old, 15 children of 9 to 11 years old, and 28 adolescents of 14 to 16 years old. Evaluation of membrane receptors on B cells was performed by means of three-colour fluorescent label and allowed of characterizing B1 subpopulations (CD19+CD5+CD27-, naпve B2 cells (CD19+CD5-CD27-, and B2 memory cells (CD19+CD5-CD27+. B1 cells have been shown to dominate in blood of newborns and younger children (up to 5 years old. By the contrary, B2 memory cells were nearly undetectable in newborns, and exceeded 20% in adolescents (by 15 years old. Meanwhile, it has been revealed that the amounts of IgG1 and IgG3 subclasses did progressively increase with age, whereas IgG2 remained decreased to 50% of adult values for a long time, and reached them by 11 years and later. We suggest that the age dynamics of IgG subclasses is connected with age-dependent changes in B cell subpopulations.

    5-Amino-3-methyl-4-isoxazolecarboxylic acid hydrazide is a non-cytotoxic synthetic isoxazole derivative with considerable immunomodulatory properties demonstrated in in vitro experiments. The aim of this study was to investigate the influence of this compound, depending on the dosage and schedule of treatment, on lymphocyte subsets in non-immunized mice and humoral immune response in SRBC (sheep red blood cells)-immunized mice. An analysis of lymphocyte subsets was carried out by flow cytometry, using specific monoclonal antibodies stained with fluorescein isothiocyanate (FITC) or phycoerythrin (PE). In the SRBC-immunized mice, the influence of the compound on the humoral response was determined, depending on the time of administration relative to the antigen. The number of plaque forming cells (PFC) was determined by a local hemolysis technique in an agar gel. Total and 2-mercaptoethanol resistant serum agglutination titers were defined by active hemagglutination test carried out on microplates. The investigated hydrazide was able to modulate the percentage and absolute number of T lymphocyte subsets in the thymus, and T and B lymphocytes in the peripheral lymphatic organs. It also enhanced humoral immune response in SRBC-immunized mice by increasing the number of cells producing hemolytic anti-SRBC antibodies (PFC) and by augmenting the level of total and 2-mercaptoethanol resistant hemagglutinin. The present study showed modulatory effects of 5-amino-3-methyl-4-isoxazolecarboxylic acid hydrazide on lymphocyte subsets and humoral immune response in mice. This compound could be potentially useful for the treatment of autoimmune diseases, infections or as an adjuvant for boosting the efficacy of vaccines. PMID:25572572

    Full Text Available Robust humoral and cellular immunity are critical for survival in humans during an ebolavirus infection. However, the interplay between these two arms of immunity is poorly understood. To address this, we examined residual immune responses in survivors of the Sudan virus (SUDV outbreak in Gulu, Uganda (2000–2001. Cytokine and chemokine expression levels in SUDV stimulated whole blood cultures were assessed by multiplex ELISA and flow cytometry. Antibody and corresponding neutralization titers were also determined. Flow cytometry and multiplex ELISA results demonstrated significantly higher levels of cytokine and chemokine responses in survivors with serological neutralizing activity. This correspondence was not detected in survivors with serum reactivity to SUDV but without neutralization activity. This previously undefined relationship between memory CD4 T cell responses and serological neutralizing capacity in SUDV survivors is key for understanding long lasting immunity in survivors of filovirus infections.

    Acute humoral rejection (AHR) is uncommon after ABOcompatible liver transplantation. Herein, we report two cases of AHR treated with plasmapheresis and rituximab in two ABO-compatible liver-transplant patients with preformed anti-human leukocyte antigen donor-specific antibodies. Patient 1 experienced a biopsy-proven AHR at day 10 post-transplant. She was treated by steroid pulses, and OKT3. Because of persisting signs of biopsy-proven AHR at day 26, she was treated by plasmapheresis and rituximab. Liver enzyme levels did not improve, and she died on day 41. Patient 2 experienced a biopsy-proven AHR on day 10 post-transplant. She was treated by steroid pulses, plasmapheresis, and rituximab.Liver enzymes returned to within normal range 18 dafter diagnosis. Liver biopsies, at 3 and 9 mo post-transplant,showed complete resolution of AHR. We conclude that plasmapheresis should be started as soon as AHR is diagnosed, and be associated with a B-cell depleting agent. Rituximab may be considered as a first-line therapy.

  8. The effect of thymic humoral factor upon regeneration of lymphatic and haemopoietic tissues of irradiated mice

    International Nuclear Information System (INIS)

    The effect was investigated of the humoral factor isolated from the calf thymus (thymosin) upon the regeneration of lymphatic and haemopoietic tissues of female (CBAxC57BL/10ScSn)F1 mice whole-body irradiated with 500R or 600R of gamma rays. Thymosin was applied subcutaneously in an amount of 5 mg per mouse per day. Two application schemes were used, i.e., the first dose given immediately after irradiation, followed by one injection daily for a total of either 3 or 9 days, or the first dose given 3 days prior to radiation exposure, followed by one injection daily for a total of 7 days. The number of endogenous spleen colonies, 59Fe splenic uptake, and dry spleen weight, all estimated on the 9th day after irradiation, were significantly higher in both experimental groups treated with thymosin as against untreated controls. If the start of the treatment preceded the irradiation, the ESC number increased as much as five times beyond the level found in the irradiated untreated group and the 59Fe uptake even exceeded the values of iron incorporation in nonirradiated mice. Stimulation of lymphopoiesis induced by thymosin was reflected in an increase in 2-14C-thymidine incorporation into DNA of the spleen, thymus and lymph nodes, measured 72 hours after irradiation.

    Full Text Available Parvoviral infections are a big medical and economic problem, in particular in large dog-breeding facilities. Having in mind the manner in which this infection is spread (fecal-oral pathways, and the strong resistence of parvoviruses to the outer environment, general and immunoprophylaxis have a significant role in the control of this dangerous disease. This work examines the humoral immunological response of pregnant bitches, vaccinated with an inactivated vaccine against parvoviral infection in dogs. An experiment was performed on 10 pregnant bitches which were vaccinated on the 42nd day of gravidity with an inactivated vaccine, and an IHA test proved the lowest titer of antibodies was 1:1280, and the highest 1:20480. The titer of pregnant bitches before vaccination ranged from 1:80 to 1:320. These investigations indicate that puppies of vaccinated bitches receive the corresponding level of immunoglobulin through colostrum, and are protected from parvoviral infection in the first 6-7 weeks of life.

    Adeno-associated virus (AAV)-6, 8, and 9 are promising gene-delivery vectors for testing novel Duchenne muscular dystrophy gene therapy in the canine model. Humoral immunity greatly influences in vivo AAV transduction. However, neutralizing antibodies to AAV-6, 8, and 9 have not been systemically examined in normal and dystrophic dogs. To gain information on the seroprevalence of antibodies to AAV-6, 8, and 9, we measured neutralizing antibody titers using an in vitro transduction inhibition assay. We examined 72 naive serum samples and 26 serum samples obtained from dogs that had received AAV gene transfer. Our data demonstrated that AAV-6 neutralizing antibody was the most prevalent antibody in dogs irrespective of age, gender, disease status (dystrophic or not), and prior parvovirus vaccination history. Surprisingly, high-level anti-AAV-6 antibody was detected at birth in newborn puppies. Further, a robust antibody response was induced in affected, but not normal newborn dogs following systemic AAV gene transfer. Taken together, our data have provided an important baseline on the seroprevalence of AAV-6, 8, and 9 neutralizing antibodies in normal and Duchenne muscular dystrophy dogs. These results will help guide translational AAV gene-therapy studies in dog models of muscular dystrophy. PMID:22040468

To define potential candidate protein markers of RVO, proteomic analysis was performed on RVO patients (n = 30 and compared with controls (n = 16. To determine validity of potential biomarker candidates in RVO, receiver operating characteristic (ROC was performed by using proteome data of independent RVO (n = 14 and control samples (n = 8.Ninety-four different proteins (736 tryptic peptides could be identified. Sixteen proteins were found to be significant when comparing RVO and control samples (P = 1.43E-05 to 4.48E-02. Five proteins (Clusterin, Complement C3, Ig lambda-like polypeptide 5 (IGLL5, Opticin and Vitronectin, remained significant after using correction for multiple testing. These five proteins were also detected significant when comparing subgroups of RVO (central RVO, hemi-central RVO, branch RVO to controls. Using independent samples ROC-Area under the curve was determined proving the validity of the results: Clusterin 0.884, Complement C3 0.955, IGLL5 1.000, Opticin 0.741, Vitronectin 0.786. In addition, validation through ELISA measurements was performed.The results of the study reveal that the proteomic composition of VH differed significantly between the patients with RVO and the controls. The proteins identified may serve as potential biomarkers for pathogenesis induced by RVO.

    Full Text Available Dengue viruses (DENV are the most important mosquito transmitted viral pathogens infecting humans. DENV infection produces a spectrum of disease, most commonly causing a self-limiting flu-like illness known as dengue fever; yet with increased frequency, manifesting as life-threatening dengue hemorrhagic fever (DHF. Waning cross-protective immunity from any of the four dengue serotypes may enhance subsequent infection with another heterologous serotype to increase the probability of DHF. Decades of effort to develop dengue vaccines are reaching the finishing line with multiple candidates in clinical trials. Nevertheless, concerns remain that imbalanced immunity, due to the prolonged prime-boost schedules currently used in clinical trials, could leave some vaccinees temporarily unprotected or with increased susceptibility to enhanced disease. Here we develop a DENV serotype 1 (DENV-1 DNA vaccine with the immunodominant cross-reactive B cell epitopes associated with immune enhancement removed. We compare wild-type (WT with this cross-reactivity reduced (CRR vaccine and demonstrate that both vaccines are equally protective against lethal homologous DENV-1 challenge. Under conditions mimicking natural exposure prior to acquiring protective immunity, WT vaccinated mice enhanced a normally sub-lethal heterologous DENV-2 infection resulting in DHF-like disease and 95% mortality in AG129 mice. However, CRR vaccinated mice exhibited redirected serotype-specific and protective immunity, and significantly reduced morbidity and mortality not differing from naïve mice. Thus, we demonstrate in an in vivo DENV disease model, that non-protective vaccine-induced immunity can prime vaccinees for enhanced DHF-like disease and that CRR DNA immunization significantly reduces this potential vaccine safety concern. The sculpting of immune memory by the modified vaccine and resulting redirection of humoral immunity provide insight into DENV vaccine induced immune

  15. Removal of low level of 239+240Pu in aqueous solution between pH 2-6 by calcium alginate and its variation with aquatic humic substance

    International Nuclear Information System (INIS)

    During this work laboratory simulated experiments were carried out for the removal of low level of 239+240Pu from the aqueous solution. Water samples after filtering through 0.22 mm filter paper were spiked with 250 Bq/1 of 239+240Pu as Pu(NO3)4. The pH of the solutions were controlled between 2-6 by using 0.01M NaOH/HNO3. Spiked samples were kept in the argon atmosphere for a week. The spiked water is passed separately through 20 cm column having about 4 gm of calcium alginate beads. Calcium-alginate beads were prepared by immobilising 2% sodium alginate in 0.2 M calcium chloride solution. At different pH about 95-98% Pu was retained in the beads and significant variation was not observed at pH range studied. To understand the impact of dissolved organic substance on the absorption characteristics of Pu(IV) on calcium-alginate beads, about 0.01% (weight/volume) humic acid solution was mixed in the ratio of 1-4/100 (V/V) experimental solutions. It was observed that the presence of organic matter decreased the absorption by 40% which clearly indicate the complexation of Pu(IV) with humic acid, which was not further forming complex within the alginate beads. The various physicochemical characteristics were measured before and after passing the solution. About 40% of Pu is recovered from sodium alginate beads by using 0.1 M HNO3. (author)

    Full Text Available Teacher’s sense of humor is like a miracle in creating effective teaching and learning environments where there is no place for stress and anxiety but instead intrinsic motivation is enhanced. The present study aims mainly, to explore the effects of teachers’ sense of humor of EFL intermediate learners' reading comprehension ability. Having administered a test of reading proficiency, 58 learners are selected and assigned into control and experimental groups. Also two English language teachers, based on TOEFL and Humor Questionnaire, are selected to teach these learners. The process of teaching and the materials were the same for both groups. But participants in humor class were taught in a well-defined humorous environment managed by the teacher. Considering the control group, the process of teaching reading texts was conducted in a normal manner. To measure the relationship between EFL teachers’ sense of humor and EFL learners' intrinsic motivation in reading comprehension ability, an Intrinsic Motivation in Reading Questionnaire (IMERQ including reading curiosity, is given to experimental participants both at the outset and at the end of the course. Finally based on the data, it was found that teachers’ sense of humor was effective in improving learners' reading comprehension ability and enhancing intrinsic motivation. The findings can also provide pedagogical implications for considering teachers’ sense of humor as an intrinsically motivating learning tool.Keywords: sense of humor, intrinsic motivation, reading comprehension, intermediate

    The nursing profession has generally accepted humor as beneficial to health care. As nursing has always emphasized holistic care and the importance of individual needs, the profession values the ability of humor to positively affect all aspects of a patient's well being. The purposes of this study were to develop a "Chinese Humor Scale (CHS)" for the nursing profession and then test its reliability and validity. The 405 individuals selected for participation in this study included nursing on-the-job students from a medical university and professional nurses practicing at four hospitals in north Taiwan. Researchers developed a list of 57 key humor measures which were filled out and returned by study participants. An evaluation of results using Cronbach's alpha coefficients demonstrated good consistency (alpha=.93) for the developed CHS. Intercorrelations amongst the four sub-scales were generally quite low, indicating each sub-scale measures dimensions relatively distinct from one another (r=.24 approximately .48, both p'shumorous creativity", "tendency to laugh", "perceptivity to humor", and "humorous attitude", were found to explain 55.42% of total variances. The CHS was found to provide good validity using a content validity index (CVI) developed by five experts. The results of this study provide encouraging evidence for the construct validity and reliability of the proposed humor scale and support its application by nursing educators and clinicians to further test and assess concepts related to humor. Further research is needed to explore more fully the implications of humor in nursing. PMID:16237632

  18. Precipitation of neptunium dioxide from aqueous solution

    Energy Technology Data Exchange (ETDEWEB)

    Roberts, K E

    1999-12-01

    Tens of thousands of metric tons of highly radioactive, nuclear waste have been generated in the US. Currently, there is no treatment or disposal facility for these wastes. Of the radioactive elements in high-level nuclear waste, neptunium (Np) is of particular concern because it has a long half-life and may potentially be very mobile in groundwaters associated with a proposed underground disposal site at Yucca Mountain, Nevada. Aqueous Np concentrations observed in previous, short-term solubility experiments led to calculated potential doses exceeding proposed long-term regulatory limits. However, thermodynamic data for Np at 25 C showed that these observed aqueous Np concentrations were supersaturated with respect to crystalline NpO{sub 2}. It was hypothesized that NpO{sub 2} is the thermodynamically stable solid phase in aqueous solution, but it is slow to form in an aqueous solution of NpO{sub 2}{sup +} on the time scale of previous experiments. The precipitation of NpO{sub 2} would provide significantly lower aqueous Np concentrations leading to calculated doses below proposed regulatory limits. To test this hypothesis, solubility experiments were performed at elevated temperature to accelerate any slow precipitation kinetics. Ionic NpO{sub 2}{sup +} (aq) was introduced into very dilute aqueous solutions of NaCl with initial pH values ranging from 6 to 10. The reaction vessels were placed in an oven and allowed to react at 200 C until steady-state aqueous Np concentrations were observed. In all cases, aqueous Np concentrations decreased significantly from the initial value of 10{sup {minus}4} M. The solids that formed were analyzed by x-ray powder diffraction, x-ray absorption spectroscopy, and scanning electron microscopy. The solids were determined to be high-purity crystals of NpO{sub 2}. This is the first time that crystalline NpO{sub 2} has been observed to precipitate from NpO{sub 2}{sup +}(aq) in near-neutral aqueous solutions. The results obtained

    2014-12-01

    Full Text Available With a diversity of promotional channels and ever-increasing numbers of participants, the tourism industry in Taiwan faces keen competition. Along with the direct cross-strait flights policy, groups like Eastern Multimedia Group, Tsann Kuen Enterprise Company Limited and Want Want China Times Group have founded travel agencies for the purpose of increasing their market share in the tourism industry. Therefore, the formulation of marketing strategies has become a critical issue for all travel agencies that wish to ensure their prominence in the market. The frequent use of humorous materials and appeals has been the main tendency in advertising. However, no consistent conclusions regarding the actual effects of humorous advertising have been determined. The subjects of the current study were users of the Lion Travel website. Online questionnaires were sent to and collected from random respondents. One hundred questionnaires were delivered, and 512 valid questionnaires were collected. Each collected questionnaire represented a valid sample. The study generated the following five results: (1 humorous advertisements may partially influence brand awareness; (2 humorous elements may partially influence advertising effects; (3 brand awareness has significant positive effects on the advertising attitude of advertising effects; (4 brand awareness has significant positive effects on the brand attitude of advertising effects; (5 brand awareness has significant positive effects on the purchasing intention of advertising effects. Eventually, it is anticipated that the results of this study can serve as a reference and provide suggestions for humorous advertising strategies in the tourism industry.

  2. Helminth Protein Vaccine Induced Follicular T Helper Cell for Enhancement of Humoral Immunity against Schistosoma japonicum

    2013-01-01

    Full Text Available Protein vaccines combined with adjuvants have been widely used to induce immune responses, especially the humoral immune response, against molecular targets including parasites. Follicular T helper (Tfh cells are the specialized providers of B-cell help, however, the induction of Tfh cells in protein vaccination has been rarely studied. Here, we report that the Schistosoma japonicum recombinant protein (SjGST-32 combined with tacrolimus (FK506 augmented the induction of Tfh cells, which expressed the canonical markers CXCR5, BCL6, and IL-21, and enhanced the humoral immune responses in BALB/c mice. Furthermore, the expression of IL-21R on germinal center (GC B cells and memory B cells increased in immunized mice, which indicated that IL-21 from the induced Tfh cells interacted with IL-21R for activation of B cells and maintenance of long-lived humoral immunity. Our results suggest that helminth protein vaccine combined with FK506 induces Tfh cell for stimulating humoral immune responses and inducing long-lived humoral immunity.

    Spaceflights are known to induce stress and immune dysregulation. Centrifugation, as hindlimb unloading, is a good ground based-model to simulate altered gravity which occurs during space missions. The aim of this study was to investigate the consequences of a long-term exposure to different levels of hypergravity on the stress response and the humoral immunity in a mouse model. For this purpose, adult C57Bl/6J male mice were subjected for 21 days either to control conditions or to 2G or 3G acceleration gravity forces. Corticosterone level and anxiety behavior revealed a stress response which was associated with a decrease of body weight, after 21-day of centrifugation at 3G but not at 2G. Spleen lymphocyte lipopolysaccharide (LPS) responsiveness was diminished by 40% in the 2G group only, whereas a decrease was noted when cells were stimulated with concanavalin A for both 2G and 3G groups (about 25% and 20%, respectively) compared to controls. Pro-inflammatory chemokines (MCP-1 and IP-10) and Th1 cytokines (IFNγ and IL2) were slightly decreased in the 2G group and strongly decreased in the 3G mouse group. Regarding Th2 cytokines (IL4, IL5) no further significant modification was observed, whereas the immunosuppressive cytokine IL10 was slightly increased in the 3G mice. Finally, serum IgG concentration was twice higher whereas IgA concentration was slightly increased (about 30%) and IgM were unchanged in 2G mice compared to controls. No difference was observed in the 3G group with these isotypes. Consequently, functional immune dysregulations and stress responses were dependent of the gravity level. PMID:21724335

    Full Text Available Six adult horses were experimentally infected with Trypanosoma evansi (106 parasites. Three other adult horses served as negative control. Serum samples of the experimentally infected horses with T. evansi and non-infected controls horses were obtained before inoculation, and daily thereafter until 14 days post infection (DPI. After that time the serum samples were obtained weekly. Sera of the infected and non-infected control horses was tested by indirect fluorescent antibody test (IFAT and enzyme-linked immunosorbent assay (ELISA for the detection of antibodies against T. evansi. Both ELISA and IFAT detected trypanosomal antibodies shortly after infection and showed progressive increases in antibodies levels during early stages of infection. The responses started on the eighth and eleventh DPI. Maximum IFAT and ELISA values were reached after four weeks of infection and were maintained at this level until the end of the period of study.Seis eqüinos foram inoculados com 106 tripomastigota sangüícolas de Trypanosoma evansi. Três outros animais foram mantidos como testemunhas. Amostras de soro sangüíneo foram obtidas de todos os animais, antes da inoculação, e diariamente até o 14º dia pós inoculação (DPI; após este período uma vez por semana. Pesquisa de anticorpos anti- T. evansi, foram realizadas através da reação de imunofluorescência indireta (RIFI e do ensaio de imunoabsorção enzimática (ELISA. A resposta imune humoral, detectada através da RIFI e do ELISA, iniciou-se, em média, a partir do oitavo DPI, alcançando títulos máximos após quatro semanas de evolução, e os titulos de anticorpos anti- T. evansi mantiveram-se elevadas até o término das observações.

    Past research has examined the effects of entertainment narratives on story-related behaviors, but most has focused primarily on dramatic genres rather than comedy. The present study examines how the presence or absence of pregnancy-related humor influences viewers' counterarguing, perceived severity, and intentions to engage in unprotected sexual behavior. Results were consistent with expectations in that related humor reduced counterarguing while also trivializing the severity of the consequences of sexual behavior. When the pregnancy storyline was presented in its original humorous context, viewers reported greater intentions to engage in unprotected sex than when pregnancy was presented in a more serious tone. Model testing clarified this finding by revealing the underlying mechanisms. Practical and theoretical implications are discussed. PMID:21707390

    Full Text Available A humorous, an environmentally oriented and an authoritarian poster against littering were tested in a field experiment on their behavioural effectiveness. Corresponding slogans were placed on anti-littering posters designed for this study and used experimentally at four railway stations. The experimental design entailed 4 communication conditions including a control condition where no poster was presented. In each experimental run (N = 96, flyers were distributed for 30 minutes. The number of distributed flyers was counted, and the proportion of littered flyers was determined for each experimental run. It was found that the humorous and environmentally oriented posters achieved a reduction of 58% and 64%, respectively, in littering as compared with the control condition. The authoritarian poster was significantly less effective, but achieved a significant reduction of 25%. Considered together with some previous findings and theories, the results indicate that environmentally oriented and humorous anti-littering posters are more effective than authoritarian ones

    Full Text Available The influence of supplementing the diet of broiler breeder hens with arginine (Arg on their offspring's humoral and cell-mediated immune response was evaluated in two experiments. In experiments I and II, breeder hens were fed diets containing graded levels of Arg (0.943, 1.093, 1.243, 1.393 and 1.543% digestible Arg. In experiment I, the offspring was randomly grouped according to the treatment received by the breeder hens, with five levels of Arg in the maternal diet and six replicates, giving a total 30 experimental units. In experiment II, the offspring were grouped in accordance with the treatment received by the breeder hens; however, Arg was added to the starter diet (1.300, 1.450, 1.600, 1.750 and 1.900% digestible Arg and also the growing diet (1.150, 1.300, 1.450, 1.600 and 1.750% digestible Arg. Supplementation of the broiler breeder hen diet did not influence (p > 0.05 the development of the lymphoid organs (cloacal bursa, thymus and spleen of the offspring, whether their diet were supplemented or not. Nevertheless, greater weight and dimensions cloacal bursa were found in the supplemented offspring in comparison with the nonsupplemented offspring. Macrophage phagocytic activity was found to be unaffected (p > 0.05, independently of the Arg supplementation. The offspring fed with supplemented diets showed a linear reduction in the antibody titer against Newcastle Disease (p 0.05 by the breeder hen diet. This study concluded that supplementing the breeder hen diet with arginine is insufficient to improve the humoral and cellular immune response, requiring supplementation of the offspring diet.

Materials and Methods: Purified live E. tenella sporozoites were administered subcutaneously in neck region of broiler chickens in the early life (first week at different concentrations. The potency of the sporozoite vaccine as assessed by IgG levels and the performance in immunized broilers as assessed by body weight, lesion score and oocysts excretion in faeces after challenge with 10, 000 live E. tenella oocysts at 49 days of age were evaluated. Results: The chickens of group (T4 immunized with 20 µg of antigen on day 6 showed an increase in IgG levels (0.161±0.004 two weeks post immunization (PI peaking (0.399± 0.016 at 5 weeks PI. The mean weekly weight gain (g after challenge, at 56 days of age was high in T4 (148±4.751 g with a low mean lesion score (2.5±0.22 and mean oocyst output (x103 oocytes per gram (OPG in faeces (100.3± 45.72 when compared to unimmunised infected controls. Conclusion: An early but partial immune response against caecal coccidiosis could be achieved by immunization with E. tenella specific sporozoites in chickens of less than a week old. Moreover, the performance of immunized chickens as indicated by weight gain, lesion score and oocyst output was found to be superior to the unimmunized infected controls.

    Full Text Available Primary antibody deficiency (common variable immunodeficiency, Hyper IgM, X-linked agammaglobulinemia and selective Ig A deficiency is a group of heterogeneous diseases characterized by defective antibody production. In primary hypogammaglobulinemias, particularly in patients with common variable immunodeficiency there is an increased generation of reactive oxygen species from monocytes which may be important for both immunopathogenesis and clinical manifestations. The generation of toxic oxygen metabolites may contribute to inflammation and tissue damage associated with phagocytic infiltration, and play role in the pathogenesis of malignancies, autoimmune disorders, acute and chronic pulmonary diseases seen in these patients. In primary immunodeficiencies and functional antibody deficiencies, IVIG act as replacement therapy and several mechanisms of IVIG action have been postulated. In vitro studies with human granulocytes showed stimulation of respiratory burst and promotion of bacterial killing by IVIG. In adult patients with primary humoral immunodeficiency, treated with IVIG showed that IVIG does not affect superoxide generation. We investigated superoxide generation from PMNL in 35 children with hyper IgM syndrome, XLA, CVID and IgA deficiency and 13 healthy children. We also explored the effect of IVIG administration on superoxide generation from granulocytes, white cell count, absolute neutrophil count, absolute lymphocyte count and quantitative CRP levels. There was a substantial increase in superoxide generation from PMNL in patients with XLA, CVID and IgA deficiency. Comparison of the superoxide generation before, 24 hours and one week after IVIG treatment showed no difference. In patients with CVID, quantitative CRP levels before and 24 hours after IVIG revealed significant difference. Other parameters were not changed. It can be concluded that enhanced superoxide generation in patients with XLA, CVID, Ig A deficiency may result from

  3. Laughing in the Face of Fear (of Disease Detection): Using Humor to Promote Cancer Self-Examination Behavior.

    Science.gov (United States)

    Nabi, Robin L

    2016-07-01

    This research examines the possible benefit of using humor to reduce anxiety associated with performing cancer self-examination behaviors. In Study 1, 187 undergraduates read a humorous public service announcement (PSA) script promoting either breast or testicular self-exams. Results suggest that perception of humor reduced anxiety about self-exams, which, in turn, related to more positive self-exam attitudes. Simultaneously, humor perception associated with greater message processing motivation, which, in turn, associated with more supportive self-exam attitudes. Self-exam attitudes also positively associated with self-exam intentions. These results were largely replicated in Study 2. Further, self-exam intentions predicted self-exam behavior 1 week later. However, consistent with past research, the humorous and serious messages did not generate differences in subsequent self-exam behavior, though the intention-behavior relationship was stronger and significant for those exposed to the humorous versus the serious messages. In light of these findings, and given that humor has the advantage of attracting and holding attention in real message environments, the use of carefully constructed humor appeals may be a viable message strategy to promote health detection behaviors.

    Full Text Available Abstract This study evaluates the immunogenicity of the HIV envelope protein (env in mice presented either attached to γ-retroviral virus-like-particles (VLPs, associated with cell-derived microsomes or as solubilized recombinant protein (gp160. The magnitude and polyfunctionality of the cellular immune response was enhanced when delivering HIV env in the VLP or microsome form compared to recombinant gp160. Humoral responses measured by antibody titres were comparable across the groups and low levels of antibody neutralization were observed. Lastly, we identified stronger IgG2a class switching in the two particle-delivered antigen vaccinations modalities compared to recombinant gp160.

    Fifteen crocodiles were randomly divided into three groups of five animals. They represented high-infection, medium-infection and low-infection groups of 642 larvae/kg, 414 larvae/kg and 134 larvae/kg bodyweight, respectively. The parameters assessed were blood glucose, creatine phosphokinase (CPK), lactate dehydrogenase (LDH), aspartate transaminase (AST) and alanine transaminase (ALT). The humoral immune response to Trichinella zimbabwensis infection was evaluated in all three groups by an indirect ELISA method. The results showed deviations from normal parameters of blood glucose, CPK, LDH, AST and ALT when compared with reported levels in uninfected reptiles. Contrary to studies involving mammals, hypoglycaemia was not observed in the infected groups in this study. Peak values of blood glucose were reached on post-infection (PI) Day 49, Day 42 and Day 35 in the high-infection, medium-infection and low-infection groups, respectively. Peak values of LDH and AST were observed on PI Day 56, Day 49 and Day 42 in the high-infection, medium-infection and low-infection groups, respectively. Peak values of CPK were observed on Day 35 PI in all three groups. Peak ALT values were reached on Day 56 in the high-infection group and on Day 28 PI in both the medium-infection and low-infection groups. No correlations between the biochemical parameters and infection intensity were observed. Peak antibody titres were reached on Day 49 PI in the medium-infection group, and on Day 42 PI in both the high-infection and low-infection groups. Infection intensity could not be correlated with the magnitude of the humoral immune response or time to sero-conversion. Results from this study were in agreement with results reported in mammals infected with other Trichinella species and showed that antibody titres could not be detected indefinitely. PMID:25686027

  9. Aqueous chemistry of iodine

    International Nuclear Information System (INIS)

    The chemistry of iodine has been examined in aqueous solutions of pH 6 to 10 containing 2500 ppM boron as H3BO3 at temperatures up to 1500C using absorption spectrophotometry to identify and monitor the iodine species present. Kinetic rate constants for the disproportionation of the HOI intermediate, 3HOI= IO3- + 2I- + 3H+, have been measured as a function of pH even though no direct spectral evidence for HOI itself has been observed. An HOI partition coefficient >104 has been estimated; results of ionic strength tests are consistent with HOI being present as an uncharged triatomic species in solution. Redox and radiation effects on the aqueous iodine chemistry have also been described. 11 refs., 2 figs., 3 tabs

Our text is focused on significative actores implied with the magazine. In that sense, we research the intervention of its public through reader’s letters section. Our goal was to analyze controversies in that section. We assert it was a useful space in restablishing broken social links resulting from state repression. In addition to this, the reader’s section was a way so Humor could evaluate the effects of contents offered to its public.The analysis let us detect two controversies developed about relevant public matters. The first one concerns horror representation, relating the jewish genocide (Shoah; the second one dealt with how comic cartoons depicts the Other in the shape of popular classes. Both controversies oblige Humor to state explicitly the values of its editorial project and also evidenced a notorious dissent between its readers. Our contribution is intended to bring complexity to an assumed vision that relates directly actors connected with Humor magazine with oposition to dictatorial government.

    Full Text Available Mass-mediated American culture and the English language became raw materials for vernacular protest humor alongside images of headscarf-wearing middle-aged “aunties” during antigovernment protests in Turkey in the summer of 2013. Focusing on posts shared on Facebook and Twitter by Turkish protestors and their supporters in the first two months of the protests, this article studies the complex linguistic and visual humor that developed around Gezi Park and relates it to the identity politics mobilized during the resistance. Exploring how the protestors projected themselves as both cosmopolitan (through the use of American mass culture and the English language and locally rooted (through the use of auntie humor, the essay delineates how “America” can function in local Middle Eastern politics even in the absence of actual US intervention on the ground. Humor at Gezi demonstrates how closely analyzing transculturated vernacular communication can help us modify Western-derived academic theories about culture and power, making the case for incorporating the study of folklore into transnational American Studies.

    Depression is associated with an altered immune response, which could be normalized by antidepressant drugs. However, little is known about the influence of antidepressants on the peripheral immune response and function of macrophages in individuals not suffering from depression. Our studies were aimed at determining the influence of antidepressant drugs on the humoral and cellular immune response in mice. Mice were treated intraperitoneally with imipramine, fluoxetine, venlafaxine, or moclobemide and contact immunized with trinitrophenyl hapten followed by elicitation and measurement of contact sensitivity by ear swelling response. Peritoneal macrophages from drug-treated mice were either pulsed with sheep erythrocytes or conjugated with trinitrophenyl and transferred into naive recipients to induce humoral or contact sensitivity response, respectively. Secretion of reactive oxygen intermediates, nitric oxide, and cytokines by macrophages from drug-treated mice was assessed, respectively, in chemiluminometry, Griess-based colorimetry and enzyme-linked immunosorbent assay, and the expression of macrophage surface markers was analyzed cytometrically. Treatment of mice with fluoxetine, venlafaxine, and moclobemide results in suppression of humoral and cell-mediated immunity with a reduction of the release of macrophage proinflammatory mediators and the expression of antigen-presentation markers. In contrast, treatment with imipramine enhanced the humoral immune response and macrophage secretory activity but slightly suppressed active contact sensitivity. Our studies demonstrated that systemically delivered antidepressant drugs modulate the peripheral humoral and cell-mediated immune responses, mostly through their action on macrophages. Imipramine was rather proinflammatory, whereas other tested drugs expressed immunosuppressive potential. Current observations may be applied to new therapeutic strategies dedicated to various disorders associated with excessive

    Full Text Available Background & objectives: The challenge of malaria and efforts targeted at developing malaria vaccines triggeredthis study on the reactivity of IgG and its subclasses in the test serum specific to CSP. This work was directed atassessing the influence of age and gender on host humoral antibody against Plasmodium falciparum recombinantcircumsporozoite antigen in Nigerian children.Methods: In all, 67 serum samples (>10,000 parasites/μl of blood collected from malaria-infected children atthe University College Hospital, Ibadan during the transmission season were analyzed by ELISA.Results: The mean absorbance values of IgG subclasses reactive against P. falciparum CSP appeared to be agedependent and ranged from 0.01 for IgG4 in younger children to 0.95 for IgG3 in older children. The sixty-sevensubjects investigated in this study had significantly higher mean IgG1 and IgG3 than the uninfected controls(p IgG1>IgG2>IgG4 which confirmed the prevalence of the cytophilicantibodies (IgG1 and IgG3 in 65% of the malaria infected children over the non-cytophilic subclasses (IgG2and IgG4. Similarly, there was low production of IgG4 and IgG2 levels in 35% of the subjects compared withcontrol. IgG was detected in the serum of North American Subjects (NAS which served as negative control forCSP-specific IgG subclasses. Although the NAS titre was lower than that of the malaria subjects in Nigeria, itsIgG2 was, however, higher (0.16 than that of other subclasses. The mean absorbance values of total serum IgGsubclass were higher than those of IgG subclasses specific to P. falciparum circumsporozoite antigen. The meanabsorbance values of the total serum IgG subclass follows the order IgG2>IgG1>IgG4>IgG3.Interpretation & conclusion: Age and gender-dependent correlations of results suggest that acquired immunitycould play a significant role in protection from malaria. Antibody levels are higher in male than female childrenof the same age group. Antibody levels also

    Objective To determine the intraocular levels of vascular endothelial growth factor (VEGF) and platelet-derived growth factor (PDGF) in patients with neovascular glaucoma (NVG) and to evaluate the relationship between probable clinical diathesis and associated levels. Methods Experimental study. Fifty-four NVG eyes of 54 patients and 10 fresh healthy donor eyes for corneal transplantation as controls were selected. The levels of VEGF and PDGF in aqueous humor and vitreous liquid aspirates from them were measured. Of the 54 eyes, 17 had central retinal vein occlusion (CRVO), 22 had diabetic retinopathy (DR), 4 had retinal vasculitis (Eales disease),4 had retinal detachments (RD) and 7 had unidentified NVG (NA). Among them, the number of NVG cases with iris neovascularization grades Ⅰ , Ⅱ, Ⅲ and Ⅳ were 17, 12, 13 and 12, respectively,and 36 eyes were treated with prophylactic retinal photocoagulation and/or cryotherapy. The levels of VEGF and PDGF were measured using an enzyme-linked immunosorbent assay (ELISA) method. The differences in VEGF and PDGF levels between the NVG and control groups were analyzed with a Mann-Whitney U test. The differences in the various primary causes, in the iris neovascularization grades and between the prophylactic-treated and untreated groups were analyzed with ANOVA, LSD-t and independent samples t test, respectively. The correlation analysis between VEGF and PDGF levels in each group were checked with a Pearson test. Results The free VEGF and PDGF concentrations in aqueous humor from NVG patients were (926.3±223.5)ng/L and (226.2±81.5)ng/L and the concentrations in vitreous liquid were (1096.1±235.9)ng/L and (375.3±141.5)ng/L, which were higher than concentrations in normal control eyes (aqueous humor: ZVEGF=-4.993, ZPDGF=-4.891, vitreous liquid: ZVEGF=-4.991, ZPDGF=-4.992, all P=0.000). The free VEGF concentrations in aqueous humor and vitreous liquid from NVG secondary to CRVO were higher than those in the NA group

    AIM: Most studies on the immune effect of gp96 were focused on its enhancement of CTLs. It is interesting to know whether gp96 could influence the humoral immune response, and whether the recombinant N-terminal fragment of gp96 could substitute native gp96 to stimulate the immune system.METHODS: gp96 isolated from livers of normal mice and its N-terminal fragment (amino acid 22-355) expressed in E coli were used for immunization of BALb/c mice. Eight groups of mice received one of the following regiments subcutaneously in 100 μL phosphate buffered saline (PBS)at an interval of 3 wk. Group 1: PBS only; group 2:gp96 only; group 3: N-terminal fragment only; group 4: HBsAg only; group 5: HBsAg+gp96; group 6: HBsAg+N-terminalfragment; group 7: HBsAg+incomplete Freud's adjuvant; group 8: HBsAg+N-terminal fragment (95 ℃ heated for 30 min). Serum anti-HBsAg antibody levels were assayed by ELISA. CTL responses in splenocytes were analyzed by ELISPOT after the last vaccination.RESULTS: The average titer of serum anti-HBsAg antibodyin the mice immunized with HBsAg together with gp96 or its N-terminal fragment were much higher than those immunized with HBsAg alone detected by ELISA. The cellular immune response of the mice immunized with HBsAg together with gp96 or its N-terminal fragment was not different with those immunized with HBsAg alone measured by ELISPOT assay.CONCLUSION: gp96 or its N-terminal fragment greatly improved humoral immune response induced by HBsAg, but failed to enhance the CTL response, which demonstrated the potential of using gp96 or its N-terminal fragment as a possible adjuvant to augment humoral immune response against HBV infection.

  13. Raman spectroscopy application to analyses of components in aqueous solutions

    2006-09-01

    The characterization of species in aqueous solutions has presented a challenge to analytical and physical chemist, because the JR absorption of the aqueous solvent is so intense that it becomes difficult to observe the solute in the water by JR absorption. In contrast, Raman spectrum of the solute is unaffected by the water, so the weak scattering of water makes the technique well suited to aqueous samples, and the Raman spectrum exhibits well-defined bands corresponding to fundamental modes of vibration. In addition, Raman spectroscopy has some inherent advantages in aqueous solution analysis, because the spectral features of signals from different species are much more distinct, and it provides characteristic signatures for samples, such as blood, protein and cholesterol. All the advantages make Raman spectroscopy be a potential alternative for the study of aqueous solutions. Now, Raman spectroscopy has been applied to studying samples in aqueous solutions, blood serum, intracellular protein levels. Now, industrial wasted water contains many organic contaminants, and it is necessary to determine and monitor these contaminants. The paper first introduces Raman spectroscopy, and then describes its applications to determining the components in aqueous solutions, analyzes and assignes the Raman spectra of o-dichlorobenzene, o-xylene, m-xyiene and p-xylene in detail. The experimental results demonstrate that Raman spectroscopy is a particularly powerful technique for aqueous solutions analyses.

  15. The evolution and functions of laughter and humor: a synthetic approach.

    Science.gov (United States)

    Gervais, Matthew; Wilson, David Sloan

    2005-12-01

    A number of recent hypotheses have attempted to explain the ultimate evolutionary origins of laughter and humor. However most of these have lacked breadth in their evolutionary frameworks while neglecting the empirical existence of two distinct types of laughter--Duchenne and non-Duchenne--and the implications of this distinction for the evolution of laughter as a signal. Most of these hypotheses have also been proposed in relative isolation of each other and remain disjointed from the relevant empirical literature. Here we attempt to remedy these shortcomings through a synthesis of previous laughter and humor research followed by (i) a reevaluation of this research in light of theory and data from several relevant disciplines, and (ii) the proposal of a synthetic evolutionary framework that takes into account phylogeny and history as well as proximate mechanisms and adaptive significance. We consider laughter to have been a preadaptation that was gradually elaborated and co-opted through both biological and cultural evolution. We hypothesize that Duchenne laughter became fully ritualized in early hominids between 4 and 2 mya as a medium for playful emotional contagion. This mechanism would have coupled the emotions of small hominid groups and promoted resource-building social play during the fleeting periods of safety and satiation that characterized early bipedal life. We further postulate that a generalized class of nonserious social incongruity would have been a reliable indicator of such safe times and thereby came to be a potent distal elicitor of laughter and playful emotion. This class of stimuli had its origins in primate social play and was the foundation for formal human humor. Within this framework, Duchenne laughter and protohumor were well established in the hominid biobehavioral repertoire when more cognitively sophisticated traits evolved in the hominid line between 2 mya and the present. The prior existence of laughter and humor allowed them to be

    Full Text Available Although influenza causes significant morbidity and mortality in the elderly, the factors underlying the reduced vaccine immunogenicity and efficacy in this age group are not completely understood. Age and immunosenescence factors, and their impact on humoral immunity after influenza vaccination, are of growing interest for the development of better vaccines for the elderly.We assessed associations between age and immunosenescence markers (T cell receptor rearrangement excision circles - TREC content, peripheral white blood cell telomerase - TERT expression and CD28 expression on T cells and influenza A/H1N1 vaccine-induced measures of humoral immunity in 106 older subjects at baseline and three timepoints post-vaccination.TERT activity (TERT mRNA expression was significantly positively correlated with the observed increase in the influenza-specific memory B cell ELISPOT response at Day 28 compared to baseline (p-value=0.025. TREC levels were positively correlated with the baseline and early (Day 3 influenza A/H1N1-specific memory B cell ELISPOT response (p-value=0.042 and p-value=0.035, respectively. The expression and/or expression change of CD28 on CD4+ and/or CD8+ T cells at baseline and Day 3 was positively correlated with the influenza A/H1N1-specific memory B cell ELISPOT response at baseline, Day 28 and Day 75 post-vaccination. In a multivariable analysis, the peak antibody response (HAI and/or VNA at Day 28 was negatively associated with age, the percentage of CD8+CD28 low T cells, IgD+CD27- naïve B cells, and percentage overall CD20- B cells and plasmablasts, measured at Day 3 post-vaccination. The early change in influenza-specific memory B cell ELISPOT response was positively correlated with the observed increase in influenza A/H1N1-specific HAI antibodies at Day 28 and Day 75 relative to baseline (p-value=0.007 and p-value=0.005, respectively.Our data suggest that influenza-specific humoral immunity is significantly influenced by

    Full Text Available Artiklen tager udgangspunkt i en empirisk undersøgelse af hvordan danskere og franskmænd anvender og reagerer på humor og ironi i professionelle sammenhænge. Humor er i sig selv et mangefacetteret fænomen der er beskrevet i flere sproglige og ikke sproglige discipliner, men når humor studeres som et tværsprogligt og tværkulturelt fænomen, inddrages endnu flere aspekter der kalder på andre former for belysning. Humor betragtes her først som en ikke-bona-fide sproghandling der for at være vellykket via sin semantiske og pragmatiske dobbelt(tydighed skal tolkes som en bona-fide-cum-humor sproghandling. Danskeres udbredte anvendelse af humor og (selvironi, også i faglige sammenhænge, i modsætning til franskmænds præference for ordspil, forklares sprogligt via særegenheder i det danske overfor det franske sprog, og kulturantropologisk og sociologisk via forskelle i civilisationsprocesser og ledelsesstrukturer i de to kulturer. Artiklen er således et forsøg på at slå bro mellem komparativ sprogforskning og sammenlignende lande- og kulturstudier.

    Psychological stress has been shown to affect immune system status and function, but most studies of this relationship have focused on acute stress and/or laboratory situations. The present study compared total numbers of leukocytes and lymphocyte subpopulations (determined by flow cytometry) and antibody titers to latent and nonlatent viruses among a group of chronically stressed individuals living near the damaged Three Mile Island (TMI) nuclear power plant with those of a demographically comparable control group. Urinary catecholamine and cortisol levels were also examined. Residents of the TMI area exhibited greater numbers of neutrophils, which were positively correlated with epinephrine levels. The TMI group also exhibited fewer B lymphocytes, T-suppressor/cytotoxic lymphocytes, and natural killer cells. Antibody titers to herpes simplex were significantly different across groups as well, whereas titers to nonlatent rubella virus as well as IgG and IgM levels were comparable.

We then examine these two forms of humour and the effects which they produce in Jean-Michel Ribes’s text. We show the specificity of the humor of Ribes which articulates the unusual with the absurd.

    Adeno-associated virus (AAV)-6, 8, and 9 are promising gene-delivery vectors for testing novel Duchenne muscular dystrophy gene therapy in the canine model. Humoral immunity greatly influences in vivo AAV transduction. However, neutralizing antibodies to AAV-6, 8, and 9 have not been systemically examined in normal and dystrophic dogs. To gain information on the seroprevalence of antibodies to AAV-6, 8, and 9, we measured neutralizing antibody titers using an in vitro transduction inhibition ...

    Seven immature green turtles, Chelonia mydas, captured from Kaneohe Bay on the island of Oahu were used to evaluate methods for assessing their immune response. Two turtles each were immunized intramuscularly with egg white lysozyme (EWL) in Freunda??s complete adjuvant, Gerbu, or ISA-70; a seventh turtle was immunized with saline only and served as a control. Humoral immune response was measured with an indirect enzyme linked immunosorbent assay (ELISA). Cell-mediated immune response was measured using in vitro cell proliferation assays (CPA) using whole blood or peripheral blood mononuclear cells (PBM) cultured with concanavalin A (ConA), phytohaemagglutinin (PHA), or soluble egg EWL antigen. All turtles, except for one immunized with Gerbu and the control, produced a detectable humoral immune response by 6 weeks which persisted for at least 14 weeks after a single immunization. All turtles produced an anamnestic humoral immune response after secondary immunization. Antigen specific cell-mediated immune response in PBM was seen in all turtles either after primary or secondary immunization, but it was not as consistent as humoral immune response; antigen specific cell-mediated immune response in whole blood was rarely seen. Mononuclear cells had significantly higher stimulation indices than whole blood regardless of adjuvant, however, results with whole blood had lower variability. Both Gerbu and ISA-70 appeared to potentiate the cell-mediated immune response when PBM or whole blood were cultured with PHA. This is the first time cell proliferation assays have been compared between whole blood and PBM for reptiles. This is also the first demonstration of antigen specific cell-mediated response in reptiles. Cell proliferation assays allowed us to evaluate the cell-mediated immune response of green turtles. However, CPA may be less reliable than ELISA for detecting antigen specific immune response. Either of the three adjuvants appears suitable to safely elicit a

    BACKGROUND: Gestational zinc deficiency has been confirmed to impair the infant immune function. However, knowledge about effects of maternal mild zinc deficiency during pregnancy on hepatitis B vaccine responsiveness in offspring is limited. In this report, we aimed to examine how maternal zinc deficiency during pregnancy influences humoral and cellular immune responses to hepatitis B vaccination in offspring of BALB/c mice. METHODOLOGY/PRINCIPAL FINDINGS: From day 1 of pregnancy upon delive...
