Mechanism underlying inhibition of inflammatory responses induced by α7nAChR agonist postconditioning alone or in combination with remote limb ischemic postconditioning during myocardial I/R in rats: the relationship with GSK-3β

Objective To evaluate the relationship between the mechanism underlying inhibition of inflammatory responses induced by α7 nicotinic acetylcholine receptor(α7nAChR)agonist postconditioning alone or in combination with remote limb ischemic postconditioning during myocardial ischemia-reperfusion(I/R)and glycogen synthase kinase-3β(GSK-3β)in rats. Methods Eighty adult male Sprague-Dawley rats, aged 8 weeks, weighing 290-320 g, were divided into 4 groups(n=20 each)using a random number table: I/R group, α7nAChR agonist postconditioning group(group P), remote limb ischemic postconditioning group(group L)and α7nAChR agonist postconditioning plus remote limb ischemic postconditioning group(group P+ L). Myocardial I/R was induced by 30 min occlusion of the left anterior descending branch of coronary artery followed by 120 min reperfusion.Specific α7nAChR agonist PNU282987 2 mg/kg was intravenously injected immediately before reperfusion in group P. In group L, limb ischemia was induced by tourniquet occlusion of bilateral hind paws for 10 min starting from 20 min of myocardial ischemia, and the tourniquet was released at the beginning of reperfusion.Combination of intervention measures previously described in P and L groups was performed in group P+ L.Venous blood samples were taken at 120 min of reperfusion for determination of serum troponin I(TnI)and creatine kinase-MB(CK-MB)concentrations, myocardial infarct size(IS)and expression of phosphorylated GSK-3β [p-GSK-3β(Ser536)], NF-κBp65 and phosphorylated nuclear factor-κBp65(p-NF-κBp65)in myocardial tissues(by Western blot). Results Compared with group I/R, myocardial IS and serum cTnI and CK-MB concentrations were significantly decreased, the expression of p-GSK-3β(Ser9)in ischemic area was up-regulated, and the expression of p-NF-κBp65 in ischemic area was down-regulated in P, L and P+ L groups(P<0.05). Compared with group L, myocardial IS and serum cTnI and CK-MB concentrations were significantly decreased, the expression of p-GSK-3β(Ser9)in ischemic area was up-regulated, and the expression of p-NF-κBp65 in ischemic area was down-regulated in group P+ L(P<0.05). Conclusion The mechanism by which α7nAChR agonist postconditioning alone or in combination with remote limb ischemic postconditioning inhibits inflammatory responses during myocardial I/R may be related to inhibiting GSK-3β activity in rats. Key words: Myocardial reperfusion injury; Inflammation; Glycogen synthase kinase 3; Cholinergic agonists; Extremities; Ischemic postconditioning
Postcolumn derivatization liquid chromatographic method for paralytic shellfish toxins

More than 20 analogues of saxitoxin occur naturally. An accurate analytical method applicable to all saxitoxins is required because of the recent findings that decarbamoyl toxins and C (N- sulfocarbamoyl-11-hydroxysulfate) toxins are metabolites of marine animals or major products of some dinoflagellate species. Almost all the toxins could be determined by ion-interaction chromatography on a silica-based reversed-phase (C 8 ) column with postcolumn periodate oxidation and fluorescence detection. Toxin groups of different net charges were separately determined by isocratic elution using different mobile phases. For determination of the saxitoxin group (net charge, 2+) and the gonyautoxin group (net charge, 1+), use of 1-heptanesulfonate as counterion, with or without acetonitrile in the mobile phase, resulted in resolution of decarbamoyl toxins from their carbamate analogues. C toxins having both N-sulfocarbamoyl and 11-hydroxysulfate moieties on the same molecule were completely resolved using the tetrabutylammonium ion. High sensitivity with detection limits ranging from 20 to 110 fmol were achieved as a result of reduced band broadening and optimized reaction conditions. For applications to biological matrixes, a cleanup procedure using a C 18 solid-phase extraction cartridge was effective in preventing false peaks. When applied to low-toxicity shellfish, the liquid chromatographic method gave higher values than the standard mouse bioassay, because of underestimation by the bioassay

Bacterial Assessment among Traditional Food Handlers and Their Behavior Related to Hygiene and Sanitation

The foodborne disease still become significant health problems in the developing region. As the primary school-age children were most affected, regulation to reduce its incidence is necessary. Food-handlers are one of the sources of transmission, particularly in a school environment. Our study aimed to provide bacterial assessment among traditional food-handlers in two different public primary schools, Public Primary School 064024, Prona Satu St and Public Primary School 066656, Karya Sembada St, in Medan Selayang sub-district, Medan, Indonesia. We conducted a descriptive study enrolled 22 traditional foodhandlers and evaluated their behavior related to hygiene and sanitation by using fundamental principles rules released by the Ministry of Health of Republic of Indonesia No.942/MENKES/SK/VII/2003. We found that all food-handlers did not perform basic principles rules and categorized as ineligible. While, 18 of 22 (81.8%) traditional food-handlers carried bacterial pathogen species including Escherichia coli (50%), Staphylococcus aureus (22.72%), and Klebsiella spp (9.09%).

Single Women’s Potency to Achieve Psychological Well-being

: This research aims to explore the personal and social context of single women that can contribute to psychological well-being. It is necessary as the percentage of single women has been increasing and previous research showed that single women can achieve happiness in life, despite negative stigma from environment. There is lack of explanation on the process and protective factors, especially in Indonesia. Data collected from forty-one Indonesian single women aged 25-70 years old help us to understand the psychological well-being accomplishment of single women. Respondent were gathered through purposive sampling. An open-ended questionnaire was used as measurement tool. Respondents were tasked to answer about the reason to stay single, emotional experience, thoughts about their life, social judgement toward the status, how they cope with problems, effort to gain a purpose and meaningful life and the reason to be happy. Data gathered were analyzed by a descriptive content analysis. Results showed that personal and social context of single women are potential to support them to achieve psychological well-being.
Determination of chemical composition, in vitro dry matter digestibility and in vitro gas production of forage by near-infrared reflectance spectroscopy

One hundred dried samples of forage, harvested three or four times during 1997 and 1999 in different morphological stages were analysed for chemical composition, in vitro dry matter digestibility (IVDMD; Tilley and Terry, 1963) and in vitro gas production (Menke and Steingass, 1988) by laboratory methods and by near infrared reflectance spectroscopy (NIRS). NIRS predicted the main chemical components, such as crude protein, crude fibre, neutral detergent fibre, acid detergent fibre, with a very high degree of accuracy (i.e. the determination coefficient (R2) varied from 93.5 % for ADF to 98,2 % for NDF), while the coefficients of determination of crude ash, ether extract and acid detergent lignin were 79.6, 85.1 and 82.3 %, respectively, with standard errors of cross validation (SECV) exceeding 9.0 %. The IVDMD was also determined with a high degree of accuracy (R2 = 94.3 %; SECV = 4.3 %), such as parameters of gas production "B" (total gas production) and "A" (constant factor describing the decay in specific gas production rate), estimated with the Gompertz model, which have R2 and SECV values of 93.0 and 3.8 % and 94.5 and 8.0 %, respectively. The parameter "C" (the specific fermentation rate) was predicted with a somewhat lower degree of accuracy (R2 = 78.3 and SECV = 9.6 %).
EXPLORING THE FACTORS IN VISITORS’ BEHAVIORAL INTENTIONS – MEDIATION EFFECTS ON PERCEIVED ENVIRONMENTAL INVOLVEMENT AND ECOTOURISM SUPPORT

Based on resource-based theory and theory of planned behavior, this study aims to explore potential visitors’ behavioral intentions to ecotourism and the interaction relations among variables of perceived environmental involvement, ecotourism support, as the mediators, and behavioral intentions, as the dependent variable. Selecting ecotourism in Sichuan Province for the research, the visitors proceeded to fill the questionnaire survey, from the potential visitors’ point of view about ecotourism. A total of 348 valid copies were retrieved for the analysis of parameter estimation. They reveal positive and significant effects of visitors’ innovation and interests on perceived environmental involvement, visitors’ interests and perceived environmental involvement on support, as well as visitors’ perceived environmental involvement and support on behavioral intentions. It is further discovered that “interests” play the key factor in driving the intention of visitors’ future selection of ecotourism products. The research results provide suggestions and reference for related units in Sichuan Province developing and promoting ecotourism.
Physiological Response and Mineral Concentration of Sago Palm under Diurnal Changes of NaCl Concentration in Culture Solution

Sago palm seedlings were exposed to 2 cycles of diurnal change of NaCl concentration in the culture solution in a hydroponic system for 4 months. During the experiment, the emergence rate of new leaves in the treated plants tended to be slow, compared to that of the control plants. However the number of dead leaves was the same in both control and treated plants. The total N and P concentrations in the leaflets and petioles and the leaf area at each leaf position did not change with the treatment. The increase of the SPAD value was slow in the treated plants. The photosynthetic rate, transpiration rate and stomatal conductance in the treated plants decreased by about 40%. The Na+ concentration increased in all the plant parts with the treatment, especially in the roots and petioles at the lower leaf positions. The K+ concentration decreased in the roots and petioles, whereas it increased in some leaflets. Although a large difference in the decrease in Mg2+ concentration was found in the cortex, the difference was negligible in the stele of adventitious roots, petioles and leaflets. Based on these results, it is considered that sago palm plants growing in a brackish water area are able to maintain a low Na+ concentration in the leaflets of active leaves by storing Na+ mainly in the roots and petioles. The factor limiting the photosynthetic rate under NaCl stress was the reduction in stomatal conductance that resulted from a trade-off with the decrease in the transpiration rate for maintaining the water status in the leaves. Although chlorophyll production was depressed, the absorption of macronutrients was not inhibited by salt stress and there was no lack of materials such as N and Mg for chlorophyll production. Therefore, it was found that the chlorophyll concentration could increase up to high levels over a comparatively long time. These factors may account for the resistance of sago palm to salt stress and ability to grow even with a reduction of the growth rate.
Can Subjective Well-being Achieved on Early Marriage among Madurese Women?

: Data shows that Madura became one of the regions in Indonesia with the highest early marriage. Many kinds of literature also stated that early marriage brings adverse effects to individual psychological development. However, it does not always seem like so for Madurese Women married in such early age. Previous study results found that Madurese women managed to achieve harmony and happiness in her early marriage. Data also shows that those who had early marriage claimed to be able to reach subjective welfare. This research aimed to investigate further of the result on previous researches which discuss subjective well-being on Madurese Women who had an early marriage. Study of narrative literature was used as the methodology in this research. Results show that SES, education, religion, tradition, matchmaking since childhood, jampi-jampi (black magic practices), and manipulating married age were several factors which contributed to early marriage in Madurese. Prior research also found problems appeared in early marriage on Madurese such as domestic disharmony, difficulty in fulfilling household needs, parenting and child education issues, and incompatibility to partner which leads to divorce. Nevertheless, this research also found that Madurese women on early marriage could find harmony and happiness which could lead to achieving subjective well-being.
Multipactor in low pressure gas and in nonuniform rf field structures

Resonant electron multiplication in vacuum, multipactor, is analysed for several geometries where the RF electric field is nonuniform. In particular, it is shown that the multipactor behaviour in a coaxial line is both qualitatively and quantitatively different from that observed with the conventionally used simple parallel-plate model. Analytical estimates based on an approximate solution of the non-linear differential equation of motion for the multipacting electrons are supported by extensive particle-in-cell simulations. Furthermore, in a microwave iris the electrons tend to perform a random walk in the axial direction of the waveguide due to the initial velocity distribution. The effects of this phenomenon on the breakdown threshold are analysed. The study shows that the threshold is a function of the height-to-length ratio of the iris and for a fixed value of this ratio, the multipactor susceptibility charts can be generated in the classical engineering units. Using the parallelplate concept, the multipactor threshold in low pressure gases has been analysed using a model for the electron motion that takes into account three important effects of electron-neutral collisions, viz. the friction force, electron thermalisation, and impact ionisation. It is found that all three effects play important roles, but the degree of influence depends on parameters such as order of resonance and secondary emission properties. In addition, a new method for detection of multipactor is presented. By applying a weak amplitude modulation to the input signal and performing a fast Fourier transform on the detected signal, accurate and unambiguous measurement results can be obtained. It is demonstrated how the method can be used in both single and multicarrier operation.
Dengue Virus (DENV)-1 Induces High Expression of Anti- and Pro-inflammatory Cytokines in Human Macrophages

: Dengue is caused by dengue virus (DENV) infection. The pathological mechanism of dengue infection is still poorly understood. Serotype variation and host’s immune response are thought to have roles in disease severity. This study compared the ability of four DENV serotypes (DENV-1, -2,-3,-4) isolates from Indonesia to induce the expression of anti- and pro-inflammatory cytokines in Monocyte-Derived Macrophages (MDMs) differentiated from a healthy human. Monocytes were isolated from healthy human donors and differentiated into macrophages under the stimulation of Macrophage Colony Stimulating Factor (M-CSF). Mature MDMs were infected with four different serotypes of DENV isolates from Indonesia. The resulting expression kinetics of Interferon alpha (IFN-  2) and Interleukin-10 (IL-10) as anti-inflammatory cytokines and IL-1  as pro-inflammatory cytokine was measured at six different time points using Luminex immunoassay. The presence of DENV Non-Structural Protein 1 (NS1) as a marker of virus replication was also measured using ELISA. DENV-1 showed a tendency to induce the expression of IFN  2 and IL-10 more rapidly and at a higher level than other serotypes albeit of lower NS1 expression. The expression of IL-1  was down-regulated in response to all DENV serotypes infection. This study demonstrates the differences in the ability of four DENV serotypes in regulating the expression of cytokines in MDMs with DENV-1 showed a superior inducing capability compared to other serotypes. This data provides information of possible serotype-specific
EXACERBATED ECZEMA: ROLE OF BUILT ENVIRONMENT IN INCREASING DISEASE SEVERITY AMONG PAKISTANI PATIENTS

Atopic Eczema is a non-contagious skin disease. This study was undertaken to determine the role of home environment allergens in aggravation of atopic eczema by using EASI (Eczema Area And Severity Index) and POEM (Patient Oriented Eczema Measure). Furthermore statistical analysis was conducted to ascertain contribution of indoor environment allergen in exacerbating disease severity among male and female patients in Pakistan. The results revealed that home environment allergens have the potential to increase severity of atopic eczema experienced by the patients. Paints, air quality and fabric coverings were the most eczema deteriorating elements found inside Pakistani homes.
Oscillatory Mechanisms of Successful Memory Formation in Younger and Older Adults Are Related to Structural Integrity

We studied oscillatory mechanisms of memory formation in 48 younger and 51 older adults in an intentional associative memory task with cued recall. While older adults showed lower memory performance than young adults, we found subsequent memory effects (SME) in alpha/beta and theta frequency bands in both age groups. Using logistic mixed effect models, we investigated whether interindividual differences in structural integrity of key memory regions could account for interindividual differences in the strength of the SME. Structural integrity of inferior frontal gyrus (IFG) and hippocampus was reduced in older adults. SME in the alpha/beta band were modulated by the cortical thickness of IFG, in line with its hypothesized role for deep semantic elaboration. Importantly, this structure–function relationship did not differ by age group. However, older adults were more frequently represented among the participants with low cortical thickness and consequently weaker SME in the alpha band. Thus, our results suggest that differences in the structural integrity of the IFG contribute not only to interindividual, but also to age differences in memory formation.
