Повний текст джерелаENGLISH ABSTRACT: The role of fructose restriction in addition to dietary modifications for weight loss and lifestyle improvement, on fertility outcome and other markers of metabolic syndrome, in obese women with polycystic ovarian syndrome (PCOS) Introduction: At the time at which the current study was undertaken no data, as yet, existed on whether restriction of fructose, while treating obese patients with PCOS for weight loss, improves the clinical symptoms and metabolic/anthropometric profile so as to promote fertility. Objectives: To evaluate the baseline intake of fructose, as well as the effect of restricting fructose intake from fruit and soft beverages to less than 20 g daily, as well as to provide guidelines for weight loss on anthropometric measurements, for improving subjective clinical symptoms, and for promoting fertility outcome in obese patients with PCOS, who seek to become fertile. Methods: The study was conducted in the Tygerberg Hospital Infertility Clinic, as an experimental cohort. Patients with a body mass index (BMI) higher than 27, seeking fertility after diagnosis with PCOS, were referred for dietary consultation, and followed up 3 monthly over 1 year. At each visit anthropometric measurements and a detailed dietary history were taken and a questionnaire for clinical symptoms was completed. Results: Baselinely, 86 patients were included in the study. Averages for weight and BMI were 99.8 ± 24.3 kg and 39.2 ± 8.7kg/m2, respectively. Average baseline daily fructose intake was 167 ± 116.8g. At baseline, significant relationships were shown between fructose intake and burning feet (ρ=0.02) and frequent waking (ρ=0.02), with a trend towards nightly eating (ρ=0.07). The dropout rate after visit 1 was 50%, with a further dropout of 41% after visit 2. After 3 visits (n=18), fructose intake significantly reduced (ρ=0.018), with the significant relationships with clinical symptoms having disappeared by visit 2. After 3 visits (n=18), both weight and BMI decreased significantly (ρ=0.017) and (ρ=0.019), respectively. Fructose was tested as a covariate to BMI, with high significance (ρ=0.006) in said population group. Conclusion: Dietary intervention to reduce fructose intake proved significant for weight loss and BMI after 3 visits. Reduced fructose intake was associated with reduced clinical symptoms. With fructose being a significant covariate to BMI, it can be concluded that fructose overconsumption could possibly contribute to both clinical symptoms and elevated BMI in said study population.
AFRIKAANSE OPSOMMING: Die rol wat die beperking van fruktose speel bykomend tot dieetaanpassings en lewenstylverbetering vir gewigsverlies by oorgewig vroue met polisistiese ovariële sindroom (PCOS) in die uitkoms van fertiliteit en ander merkers van metaboliese sindroom. Inleiding: Met die aanvang van hierdie studie was daar is geen data beskikbaar oor die invloed van die beperking van fruktose in die dieet van oorgewig pasiënte met PCOS wat vir gewigsverlies behandel word nie. Dit was ook nie bekend of laasgenoemde pasiënte se kliniese simptome en metaboliese/antropometriese profiel sou verbeter met die beperking van fruktose sodat fertiliteit by hierdie pasiënte terselfdertyd ook bevorder word nie. Doelwitte: Die evaluering van die aanvanklike inname van fruktose, sowel as die beperking van fruktose afkomstig van eetbare vrugte en versoete drankies en sap tot ’n inname van minder as 20 g daagliks, tesame met riglyne vir gewigsverlies. Die uitkoms hiervan is bepaal deur antropometriese metings, die verbetering in subjektiewe kliniese simptome en die fertiliteituitkoms by oorgewig pasiënte wat hulp met fertiliteit verlang. Metodes: Die studie het as ’n eksperimentele kohort by die Infertiliteitskliniek by Tygerberg Hospitaal plaasgevind. Pasiënte wat na diagnose met PCOS fertiliteitsbehandeling verlang het en ’n BMI hoër as 27 gehad het , is vir dieetbehandeling verwys en driemaandeliks oor ’n tydperk van een jaar opgevolg. Tydens elke besoek is antropometriese metings en ’n omvattende dieetgeskiedenis geneem en ’n vraelys oor kliniese simptome ingevul. Resultate: Aanvanklik is 86 pasiënte by die studie ingesluit. Gemiddeldes vir gewig en BMI was 99.8 ± 24.3 kg en 39.2 ± 8.7 kg/m2 respektiewelik. Gemiddelde aanvanklike daaglikse inname van fruktose was 167 ± 116.8 g. Oorspronklik het betekenisvolle verhoudings tussen fruktose en die volgende bestaan: brandvoete (ρ=0.02) en veelvuldige episodes van nagtelike wakkerheid (ρ=0.02), met ’n neiging na nagtelike etery (ρ=0.07). Die uitvalsyfer na een besoek was 50% met ’n verdere uitvalsyfer van 41% na die tweede besoek. Na drie besoeke (n=18) het sowel die gewig as die BMI betekenisvolle afname getoon (ρ= 0.017) en (ρ=0.019), respektiewelik. Fruktose is as ’n belangrike kovariant vir BMI (ρ= 0.006) vir hierdie populasiegroep geïdentifiseer. Gevolgtrekking: Dieetintervensie vir die vermindering van die inname van fruktose was beduidend vir gewigsverlies en afname in BMI na drie besoeke. Verminderde fruktose-inname het gelei tot die vermindering van kliniese simptome. Met fruktose as beduidende kovariant vir BMI kan die gevolgtrekking gemaak word dat die oor-inname van fruktose by hierdie studiepopulasie waarskynlik tot sowel kliniese simptome as BMI bygedra het.

Повний текст джерелаOs polissacarídeos são os componentes maioritários dos grãos de café verde e torrado e da bebida de café. Os mais abundantes são as galactomananas, seguindo-se as arabinogalactanas. Durante o processo de torra, as galactomananas e arabinogalactanas sofrem modificações estruturais, as quais estão longe de estar completamente elucidadas devido à sua diversidade e à complexidade estrutural dos compostos formados. Durante o processo de torra, as galactomananas e arabinogalactanas reagem com proteínas, ácidos clorogénicos e sacarose, originando compostos castanhos de alto peso molecular contendo nitrogénio, designados de melanoidinas. As melanoidinas do café apresentam diversas atividades biológicas e efeitos benéficos para a saúde. No entanto, a sua estrutura exata e os mecanismos envolvidos na sua formação permanecem desconhecidos, bem como a relação estrutura-atividade biológica. A utilização de sistemas modelo e a análise por espectrometria de massa permitem obter uma visão global e, simultaneamente, detalhada das modificações estruturais nos polissacarídeos do café promovidas pela torra, contribuindo para a elucidação das estruturas e mecanismos de formação das melanoidinas. Com base nesta tese, oligossacarídeos estruturalmente relacionados com a cadeia principal das galactomananas, (β1→4)-Dmanotriose (Man3), e as cadeias laterais das arabinogalactanas, (α1→5)-Larabinotriose (Ara3), isoladamente ou em misturas com ácido 5-Ocafeoilquínico (5-CQA), o ácido clorogénico mais abundante nos grãos de café verde, e péptidos compostos por tirosina e leucina, usados como modelos das proteínas, foram sujeitos a tratamento térmico a seco, mimetizando o processo de torra. A oxidação induzida por radicais hidroxilo (HO•) foi também estudada, uma vez que estes radicais parecem estar envolvidos na modificação dos polissacarídeos durante a torra. A identificação das modificações estruturais induzidas por tratamento térmico e oxidativo dos compostos modelo foi feita por estratégias analíticas baseadas principalmente em espectrometria de massa, mas também em cromatografia líquida. A cromatografia de gás foi usada na análise de açúcares neutros e ligações glicosídicas. Para validar as conclusões obtidas com os compostos modelo, foram também analisadas amostras de polissacarídeos do café obtidas a partir de resíduo de café e café instantâneo. Os resultados obtidos a partir dos oligossacarídeos modelo quando submetidos a tratamento térmico (seco), assim como à oxidação induzida por HO• (em solução), indicam a ocorrência de despolimerização, o que está de acordo com estudos anteriores que reportam a despolimerização das galactomananas e arabinogalactanas do café durante a torra. Foram ainda identificados outros compostos resultantes da quebra do anel de açúcares formados durante o tratamento térmico e oxidativo da Ara3. Por outro lado, o tratamento térmico a seco dos oligossacarídeos modelo (individualmente ou quando misturados) promoveu a formação de oligossacarídeos com um maior grau de polimerização, e também polissacarídeos com novos tipos de ligações glicosídicas, evidenciando a ocorrência de polimerização através reações de transglicosilação não enzimática induzidas por tratamento térmico a seco. As reações de transglicosilação induzidas por tratamento térmico a seco podem ocorrer entre resíduos de açúcares provenientes da mesma origem, mas também de origens diferentes com formação de estruturas híbridas, contendo arabinose e manose como observado nos casos dos compostos modelo usados. Os resultados obtidos a partir de amostras do resíduo de café e de café instantâneo sugerem a presença de polissacarídeos híbridos nestas amostras de café processado, corroborando a ocorrência de transglicosilação durante o processo de torra. Além disso, o estudo de misturas contendo diferentes proporções de cada oligossacarídeo modelo, mimetizando regiões do grão de café com composição distinta em polissacarídeos, sujeitos a diferentes períodos de tratamento térmico, permitiu inferir que diferentes estruturas híbridas e não híbridas podem ser formadas a partir das arabinogalactanas e galactomananas, dependendo da sua distribuição nas paredes celulares do grão e das condições de torra. Estes resultados podem explicar a heterogeneidade de estruturas de melanoidinas formadas durante a torra do café. Os resultados obtidos a partir de misturas modelo contendo um oligossacarídeo (Ara3 ou Man3) e 5-CQA sujeitas a tratamento térmico a seco, assim como de amostras provenientes do resíduo de café, mostraram a formação de compostos híbridos compostos por moléculas de CQA ligadas covalentemente a um número variável de resíduos de açúcar. Além disso, os resultados obtidos a partir da mistura contendo Man3 e 5-CQA mostraram que o CQA atua como catalisador das reações de transglicosilação. Por outro lado, nas misturas modelo contendo um péptido, mesmo contendo também 5-CQA e sujeitas ao mesmo tratamento, observou-se uma diminuição na extensão das reações transglicosilação. Este resultado pode explicar a baixa extensão das reações de transglicosilação não enzimáticas durante a torra nas regiões do grão de café mais ricas em proteínas, apesar dos polissacarídeos serem os componentes maioritários dos grãos de café. A diminuição das reações de transglicosilação na presença de péptidos/proteínas pode dever-se ao facto de os resíduos de açúcares redutores reagirem preferencialmente com os grupos amina de péptidos/proteínas por reação de Maillard, diminuindo o número de resíduos de açúcares redutores disponíveis para as reações de transglicosilação. Além dos compostos já descritos, uma diversidade de outros compostos foram formados a partir dos sistemas modelo, nomeadamente derivados de desidratação formados durante o tratamento térmico a seco. Em conclusão, a tipificação das modificações estruturais promovidas pela torra nos polissacarídeos do café abre o caminho para a compreensão dos mecanismos de formação das melanoidinas e da relação estrutura-atividade destes compostos.
Polysaccharides are the major components of green and roasted coffee beans, and coffee brew. The most abundant ones are galactomannans, followed by arabinogalactans. During the roasting process, galactomannans and arabinogalactans undergo structural modifications that are far to be completely elucidated due to their diversity and complexity of the compounds formed. During the roasting process, galactomannans and arabinogalactans react with proteins, chlorogenic acids, and sucrose, originating high molecular weight brown compounds containing nitrogen, known as melanoidins. Several biological activities and beneficial health effects have been attributed to coffee melanoidins. However, their exact structures and the mechanisms involved in their formation remain unknown, as well as the structure-biological activity relationship. The use of model systems and mass spectrometry analysis allow to obtain an overall view and, simultaneously, detailed, of the structural modifications in coffee polysaccharides promoted by roasting, contributing to the elucidation of the structures and formation mechanisms of melanoidins. Based on this thesis, oligosaccharides structurally related to the backbone of galactomannans, (β1→4)-D-mannotriose, and the side chains of arabinogalactans, (α1→5)-Larabinotriose, alone or in mixtures with 5-O-caffeoylquinic acid, the most abundant chlorogenic acid in green coffee beans, and dipeptides composed by tyrosine and leucine, used as models of proteins, were submitted to dry thermal treatments, mimicking the coffee roasting process. The oxidation induced by hydroxyl radicals (HO•) was also studied, since these radicals seem to be involved in the modification of the polysaccharides during roasting. The identification of the structural modifications induced by thermal and oxidative treatment of the model compounds was performed mostly by mass spectrometry-based analytical strategies, but also using liquid chromatography. Gas chromatography was used in the analysis of neutral sugars and glycosidic linkages. To validate the conclusions achieved with the model compounds, coffee polysaccharide samples obtained from spent coffee grounds and instant coffee were also analysed. The results obtained from the model oligosaccharides when submitted to thermal treatment (dry) or oxidation induced by HO• (in solution) indicate the occurrence of depolymerization, which is in line with previous studies reporting the depolymerization of coffee galactomannans and arabinogalactans during roasting. Compounds resulting from sugar ring cleavage were also formed during thermal treatment and oxidative treatment of Ara3. On the other hand, the dry thermal treatment of the model oligosaccharides (alone or when mixed) promoted the formation of oligosaccharides with a higher degree of polymerization, and also polysaccharides with new type of glycosidic linkages, evidencing the occurrence of polymerization via non-enzymatic transglycosylation reactions induced by dry thermal treatment. The transglycosylation reactions induced by dry thermal treatment can occur between sugar residues from the same origin, but also of different origins, with formation of hybrid structures, containing arabinose and mannose in the case of the model compounds used. The results obtained from spent coffee grounds and instant coffee samples suggest the presence of hybrid polysaccharides in these processed coffee samples, corroborating the occurrence of transglycosylation during the roasting process. Furthermore, the study of mixtures containing different proportions of each model oligosaccharide, mimicking coffee bean regions with distinct polysaccharide composition, subjected to different periods of thermal treatment, allowed to infer that different hybrid and non-hybrid structures may be formed from arabinogalactans and galactomannans, depending on their distribution in the bean cell walls and on roasting conditions. These results may explain the heterogeneity of melanoidins structures formed during coffee roasting. The results obtained from model mixtures containing an oligosaccharide (Ara3 or Man3) and 5-CQA and subjected to dry thermal treatment, as well as samples derived from spent coffee grounds, showed the formation of hybrid compounds composed by CQA molecules covalently linked to a variable number of sugar residues. Moreover, the results obtained from the mixture containing Man3 and 5-CQA showed that CQA acts as catalyst of transglycosylation reactions. On the other hand, in the model mixtures containing a peptide, even if containing 5-CQA and subjected to the same treatment, it was observed a decrease in the extent of transglycosylation reactions. This outcome can explain the low extent of non-enzymatic transglycosylation reactions during roasting in coffee bean regions enriched in proteins, although polysaccharides are the major components of the coffee beans. The decrease of transglycosylation reactions in the presence of peptides/proteins can be related with the preferential reactivity of reducing residues with the amino groups of peptides/proteins by Maillard reaction, decreasing the number of reducing residues available to be directly involved in the transglycosylation reactions. In addition to the compounds already described, a diversity of other compounds were formed from model systems, namely dehydrated derivatives formed during dry thermal treatment. In conclusion, the identification of the structural modifications in coffee polysaccharides promoted by roasting pave the way to the understanding of the mechanisms of formation of melanoidins and structure-activity relationship of these compounds.

The preparation and characterization of the modified hydrolyzed-low molecular weight poly-3-hydroxybutyrate (HLMWPHB) are studied by using gel permeation chromatography (GPC), X-ray diffraction, infrared spectroscopy (FTIR), differential scanning calorimetry (DSC), nuclear magnetic resonance spectroscopy (NMR), biodegradation test, and thermogravimetric analysis (TGA). It is shown by FTIR, NMR, and GPC that glycidyl methacrylate can be successfully reacted with the end groups of HLMWPHB. The results of DSC and X-ray diffraction indicate that the modified HLMWPHB has a lower melting temperature, lower crystallinity, slower crystallization rate, smaller crystal size, and smaller lattice parameters than PHB. The unsaturated bonds formed in the modified HLMWPHB are UV reactive. The films prepared by reacting acrylic monomers with the modified HLMWPHB under UV irradiation are biodegradable.

The wear of ultra high molecular weight polyethylene (UHMWPE) is the major cause for joint arthroplasty failure. Many studies have shown that γ-ray sterilization process before implication is the major factor to change the mechanical properties, generation of wear debris and aging behavior of UHMWPE. Crosslinking process has been well-known to improve wear resistance of UHMWPE. However, accompanied with crosslinking process, the mechanical properties of polymer, such as yield strength and anti-fatigue property, will decrease. Therefore, it becomes a crucial issue to fully understand the interaction betweenγ-ray irradiation and material properties in crosslinking process. This study detects the free radical decay curves by Electron Spin Resonance (EPR) method and measure the crosslinking density and mechanical properties of the γ-ray irradiated UHMWPE to study the free radical generation, crosslinking and oxidation mechanism of the material. Theoretical dynamic analysis indicates that the free radical decay in vacuum can be described by a modified second order reaction and the free radical decay in air can be fitted by a second order reaction. The present research also indicates that these are two reaction rate constants for the reaction of free radical decay. To describe this feature, we propose a parallel second order reaction model to simulate the dynamic behavior of the free radical decay. The results show that the present parallel model can appropriately describe free radical decay behaviors of Gamma irradiated UHMWPE kept both in vacuum and in air. Crosslinking density tests reveal that higher irradiation dose can increase crosslinking density, while, the crosslinking ratio decreases. EPR tests indicated that changing of irradiation dose and dose rate can generate different types of free radicals, which might result in different crosslinking density. The results also show that irradiation increases friction coefficient while crystallinity is not significantly changed. After annealing, crystallnity will decrease and friction coefficient will increases. With the crosslinked UHMWPE treated by accelerating aging process, the crystallinity will increase further. It reveals that UHMWPE treated by general crosslinking process cannot maintain a long-term stability during the accelerating aging process. The increases of the crystallinity during the aging process may be due to the oxidation induced by free radical residue.

The purpose of this present study was to understand how behavioral modification strategies affect the control of interdialytic weight gain knowledge, self efficacy and dialytic outcome in hemodialysis patients. Quasi-experimental design was used in this study. Patients were selected using purposive sampling at five hemodialytic center in Taipei City and County, seventy-eight sample patients were randomly assigned into experimental and control group. Subjects in both groups consisted of 39 patients and received cognitive restructuring that one to one oral teaching and a pamphlet were provided to each subjects. The teaching program focused on the patient’s individualized cognitive needs, and pamphlet focused on the utilization of salt-limited diet and fluid limitation to control their interdialytic weight gain (IDWG). The only different between experimental and control groups, was subjects in experimental group were taught to use the daily self-recording sheet to record their daily body weight and researcher provided the positive reinforcement over time. Interdialytic weight gain, change in intradialytic mean arterial pressure, subjective symptoms, and dialytic outcome were analyzed. The study results showed: (1) In the pretest, both groups of subjects showed that the knowledge of interdialysis weight gain control and the efficacy of execute fluid restricted and salt limited diet control were moderate low; especially efficacy of execute fluid restricted to control their weight gain was low. IDWG, change of interdialytic mean arterial pressure and subjective symptom were high than normal in most of subjects. However, in the dialytic outcome such as KT/V, and URR were within the normal range, but nutrition status such as albumin level was low than normal in most of subjects. (2) After cognitive restructuring, subjects in control group showed statistically significant improvement of the knowledge of IDWG control, the efficacy of execute fluid restricted and salt limited diet control, IDWG, change of intradialytic mean arterial pressure, subjective symptoms, and nutritional status. (3) After behavioral modification, subjects in experimental group showed statistically significant improvement of the knowledge of IDWG control, the efficacy of execute fluid restricted and salt limited diet control, IDWG, change of intradialytic mean arterial pressure, subjective symptoms, nutritional status, and dialysis outcome. (4)In experimental group, the subjects with lower education, older, living along, as longer as continuation of self monitoring procedures, and asked more questions did in the self monitoring periods had better improvement in the behavioral outcome. The subjects in control group, their brought questions in the telephone reminding had better improvement of the efficacy of execute fluid restricted and salt limited diet control, and well IDWG control. (5)Between the knowledge, the efficacy, and the behavioral outcome had not any directly caused-effect relationships. In sum up, both interventions produced immediate reduction in IDWG, and the effectiveness of interventions produced maintenance of improvement up to 3 months post treatment. The findings of this present study can be used as reference for nursing staff to deal with hemodialytic patients to reducing IDWG. However, combining the interventions resulted in improvement was superior to the cognitive intervention alone. The behavioral model consisted of cognitive restructuring, self monitoring, positive reinforcement, and shaping was an behavioral modification strategy for patient with individualized needs, the results of this study suggested the intervention can use to other chronic illness patients' care.

In the investigation, effects of surface modification by argon plasma on peel strength of woven type ultra high molecular weight polyethylene (UHMWPE) were studied. After plasma treated, the free radicals were generated on woven type UHMWPE surface and then converted to peroxide offer exposed to air. The concentration of peroxides were estimated by the 1,1-dipphenyl-2-picrylhydrazyl (DPPH) method. The surface morphology and the wettability of woven type UHMWPE were analyzed by scanning electron microscope (SEM) and static contact angle measurement, respectively. Identify the functional groups of the adhesive and their relative change was proved by IR to match PR. The adhesion strength of woven type UHMWPE was measured by T-peel testing method. From the results, the optimum free radical content for offering high T-peel strength was 1.27×10-9 mol/mm2 at 40 W plasma-treated for 4 min. The plasma treated woven type UHMWPE possessed the hydrophilic property and introduced the number of anchors. The adhesive 3M 1099 possessed butadiene. As it reacted with the free radicals that formed on the surface of PUHMWPE fiber, the chemical bonding significantly increased in the adhesion strength between PUHMWPE fiber and adhesive. SEM photographs shows that the surface of possessed many fibrils. This fibrils peel mechanism can offer peel strength as T-peel testing. As Surface modification by plasma treatment, the peel strength of UHMWPE fiber with adhesive 3M 4475 was increased from 1.17 to 2.26 kgf/in and the peel strength of UHMWPE fiber with adhesive 3M 1099 was increased from 2.58 to 4.39 kgf/in, respectively.

A mimic surface modification was implemented on a high pressure crystallized ultrahigh molecular weight polyethylene (UHMWPE) as an artificial cartilage material. Hyaluronic acid (HA) was coated on the UHMWPE surface pretreated by a series of processes, including the treatment of O2- plasma, ethylenediamine solution, and HA one. The modified samples were verified by water contact angle measurement, and Fourier transform infrared spectrometry. The HA layer was also quantitatively evaluated by the carbohydrate chemistry assay according to the absorbance of the incident light. The tribological performance of the samples was conducted by a pin-on-disk test rig which was lubricated by a normal saline under an average pressure of 18 MPa and a sliding speed of 0.03 m/s for 40 h. The wear resistance of the solid UHMWPE specimen is confirmed to be significantly enhanced by the HA coating. However, for the porous UHMWPE, it is not -instead.

Abdominal obesity may induce hyperinsulinemia、insulin resistance and dyslipidemia while the prevalence of abdominal obesity was increasing year by year. Therefore, to improve health of abdominal obese subjects is an urgent work. Lifestyle modification program may improve over weight, lifestyle and nutrition knowledge, and help to reduce accumulation of abdominal adipose tissue. The aim of our study was to evaluate the effectiveness of lifestyle modification program on weight control, metabolic syndrome features, behavior and health-related knowledge. We recruited 18 women aged older than 18 years whose waistline more than 80 cm, and without chronic diseases such as hypertension, diabetes and cardiovascular disease via advertisement on newspaper. We formulated a group-based weight control project upon lifestyle modification program for women with abdominal obesity. The study period was 10 weeks. Results showed that the body weight, BMI and body fat were significantly reduced. The lifestyle modification program helped to improve the waist, fasting serum sugar and high density lipoprotein concentration(p < 0.05) among metabolic syndrome features, but blood pressure and triglyceride level were no significant changes. Besides, abnormal population percentages of waist, blood pressure, fasting serum sugar and high density lipoprotein were reduced, particularly abnormal population percentages of waist. The diet behavior, physical activity behavior and health knowledge were significantly improved through the intervention. In conclution, lifestyle modification based on group-base weight control project could ameliorate the metabolic syndrome markers in abdominal obese women, and can be further applied to prevent and cure metabolic syndrome in community.

The purposes of the study is to evaluate the effect of combined group education and behavioral modification strategies on the control of knowledge, interdialytic weight gain, blood pressure and symptom experiences in hemodialysis patients. Materials included 55 purposively selected Chinese hemodialysis patients from two hospital, in southern Taiwan. This study was based on a quasi-experimental design. The design consisted of a 4-week baseline phase, a 4-week intervention phase, and another 4-week follow-up phase. Patients were assigned into the experimental group and control group, 24 and 31 patients respectively in each group. All participants received three hemodialysis treatments per week for the duration of study. Interventions included group education, self-monitoring, goal setting, stimulus control, positive reinforcement and weekly feedback about interdialytic weight gain (IDWG). The group education program focused on the utilization of salt-limited diet and fluid limitation to control their IDWG and blood pressure. Only the experimental group was taught to use the self-evaluating sheet to record their IDWG, blood pressure and symptom experiences three times per week. The experimental group received group education once a week , 30 — 40 minutes, at one hour before or after dialysis therapy. The control group received routine care. Before starting any program and also after 4 and 8 weeks, each subject was requested to complete the knowledge scales and symptom experiences questionnaires. IDWG and blood pressure were calculated for each participant during all phases. The data were analyzed by using chi-square, t-test, paired t-test and repeated measures two-way ANOVA. There were statistically significant differences of knowledge, IDWG, predialysis mean arterial pressure and symptom experiences between the baseline and intervention phases, and also between the baseline and follow-up phases. While this program was effective in improving patient’s knowledge, reducing IDWG rate, predialysis mean arterial pressure and symptom experiences, no significant differences were found for the intradialytic and postdialysis mean arterial pressure. The findings may serve as references in the courses of nephrology teaching program. The combined group education and behavioral modification strategies for hemodialysis patients could be coordinated into the clinical practice in order to enhance the quality of care.

Повний текст джерелаIn order to address the paucity of knowledge in regard to the psychological and physiological processes associated with lifelong weight loss (>20 years), this study adopts a qualitative approach informed by phenomenology to explore the experience of lifelong weight loss and maintenance of women who participated in the ITAND Programme. The research questions guiding the exploration of the current research are: (i) Which strategies from the ITAND Programme do women perceive as assisting with initial weight loss? (ii) What are the processes mediating lifelong weight loss? (iii) What strategies and skills mediate the maintenance of lifelong weight loss? (iv) What feelings or beliefs motivate women to continue attempts to lose weight after experiencing multiple failures on diets? and (v) Which psychological, cognitive and behavioural processes are identified as mediating lifelong weight loss? Eight overweight and obese women were invited to write their narratives and engage in interviews in regard to exploring their relationships with food, their bodies and their weight, after a period of more than 20 years following their participation in an integrative, transactional analysis, anti-diet programme (the ITAND Programme). Narratives were used to explore their beliefs about constructs, processes and strategies mediating long-term weight loss maintenance. The participants’ narratives and interviews were analysed through applying narrative analysis and interpretive phenomenological analysis. In addition to a non-diet paradigm, four processes definingweight loss maintenance were identified, including the adult learning process of transformative learning, the psychological process of transactional analysis, the physiological process of intuitive eating and the cognitive-behavioural processes relating to weight loss maintenance. This study contributes an integrative, transactional analysis, non-diet treatment model (ITAND model) which is enabled by the processes of transformative learning, intuitive eating and cognitive-behaviour modification to the successful long- term treatment of overweight and obesity. This model may be applied in whole or in part in a primary health care or community context. The findings of this study may be used to inform future research into the development and implementation of non-diet weight loss maintenance interventions in the treatment of overweight andobesity.

This study investigated multiobjective compromise programming models by examining the characteristics of multiobjective algorithms and compromise programming. Yu and Zeleneydeveloped compromise programming for obtaining the efficient solution closest to the ideal solution when the multiple objectives in multiobjective algorithms are inconsistent. Such an efficient solution is called a compromise solution. The compromise solution to a multiobjective problem is ultimately determined by identifying an appropriate weight among the multiple objectives. However, a disadvantage of this method is that the weight is not correlated with the objectives. In this study, an algorithm for determining the consistency between multiple objectives and a weight modification model for compromise programming were developed. Thus, improved compromise programming based on the correlation between various objectives and the weights of models is achieved, thereby enhancing the quality of multiobjective decision-making.

Повний текст джерелаIn this thesis, the integration of Neural Networks (NNs), Fuzzy Logic (FL) and Genetic Algorithms (GAs) for intelligent control is proposed and applied to the classical problem of docking a truck.
A backpropagation neural network architecture using a "step" update weight modification is used to obtain quickly and efficiently trajectory data from given initial states. A new algorithm to define fuzzy logic rules is used on the trajectory data to build a fuzzy logic knowledge base. This fuzzy logic knowledge base is then optimised using a genetic algorithm to obtain a fuzzy logic controller that effectively simulates a full neural network solution to the problem of docking of a truck.

For image processing, the color image quantization is a useful technique to produce high quality compression image. In this thesis, we present a new color image quantization technique that modifies the weighted MinMax algorithm. It is a hybrid method of MinMax and K-Means algorithms and based on weighted histogram. Instead of trying to solve an optimization problem, our algorithm is aiming to get the best-spread representation of the cluster in the color space. The main concept is based on minimizing the maximum intercluster distance. Unlike weighted MinMax algorithm, our method is more efficient and the quality of quantized image is good. In the mean time it is easy to implement also.

Inspired by the works of Hart and Mas-Colell [4], Moulin [9] and Wu and Liao [16], several axiomatizations of these weighted solutions are also proposed by adopting the reduction and related consistency proposed by Moulin [9].

Повний текст джерелаAccording to ACSM (2014), excess weight and obesity are characterized by excess of fat mass, with BMI being the most common criterion for classifying and distinguishing them. Associated with these conditions are numerous chronic pathologies including Cardiovascular Diseases (CVD), Type 2 Diabetes (T2D), various forms of cancer and various musculoskeletal problems. Physical Activity and Exercise have been shown to be beneficial for the prevention and treatment of overweight and obesity, leading to numerous changes in body composition, cardiorespiratory capacity, functional capacity, and improvements in health and psychological well-being. The experience of internships at the Ginásio Clube Português was, undoubtedly, a learning process that I take to life and that in the future I will apply at a professional level. It should be noted that I was given all the tools for this process to be completed successfully, and all thanks to the excellent supervision and conditions provided by both the institution and the multidisciplinary group involved. Some objectives were established in order to facilitate the entire internship process, and with the end of it i can say that it was possible to fulfill them in the best possible way and with the resources made available. This report addresses the issue of Weight Control and Management, and all the work developed over one year traineeship.

In this paper, we propose a new brain medical image fusion system, which fuses brain Magnetic Resonance Imaging (MRI) and Positron Emission Tomography (PET) image into one, to provide doctors an informative image in diagnosis. In our system, the primary fusion image obtained from IHS+log-Gabor fusion method is adjusted by color modification and weighted gray-level reinforcement, to acquire a high-quality fused image. Our system consists of five stages. In the first stage, PET image is converted by IHS transform to obtain hue, saturation, and intensity channels, and then decompose source images with hue channel into regions of high and low activity, respectively. In the second stage, we utilize log-Gabor wavelet to analyze regions of high and low activity, and then combine high-frequency coefficients of MRI and low-frequency coefficients of PET within these two regions. The combined coefficients are transformed by reverse log-Gabor to obtain a new gray-level intensity channel. In the third stage, the integrated gray-level intensity channel is modified based on the intensity channel of PET in order to deal with the color distortion. The modified intensity channel is then adjusted on the basis of MRI to enhance the anatomical information by weighting strategy in the fourth stage. Finally, combine the modified intensity channels of high and low regions into one, then perform reverse IHS transform with modified intensity channel, the original hue and saturation of PET image to obtain fused image. Comparing to those fused images of previously-proposed methods, ours has less color distortion and much anatomical information and improves the visual effect.
