Introdução: Alguns estudos internacionais e nacionais têm-se dedicado a estudar as caraterísticas psicológicas de profissionais/cuidadores que trabalham na área da prestação de cuidados a pessoas com doença e deficiência mental. Porém, segundo temos conhecimento são escassos ou mesmo inexistentes os estudos que abordem os níveis de autocriticismo, autocompaixão e comprometimento organizacional destes profissionais/cuidadores. Foram nossos objetivos: caraterizar uma amostra de cuidadores formais/profissionais que trabalham com pessoas com doença e deficiência mental em diferentes variáveis sociodemográficas e profissionais; analisar os níveis de autocriticismo, autocompaixão e comprometimento organizacional destes cuidadores formais/profissionais, bem como explorar as associações entre todas estas variáveis (entre si e com as variáveis sociodemográficas e profissionais). Metodologia: 55 cuidadores formais de pessoas com doença/deficiência mental (sexo feminino/n = 49, 84,5%; idade média de 45,21; DP = 10,92; variação = 22-65) preencheram um questionário sociodemográfico, o Questionário de Comprometimento Organizacional, a Escala das Formas do Autocriticismo e Autotranquilização e a Escala de Autocompaixão. Resultados: O Eu inadequado apresentou um valor médio bastante maior que o Eu detestado. O valor médio do Eu tranquilizador foi superior a qualquer dimensão de autocriticismo. O Calor-Compreensão (autocompaixão) apresentou o valor médio mais elevado e a Autocrítica o valor médio mais baixo. O Eu inadequado e detestado associaram-se positivamente às dimensões negativas de autocompaixão e o Eu tranquilizador às dimensões positivas de autocompaixão. O Comprometimento Afetivo associou-se positivamente ao Autocriticismo total. O Comprometimento Calculativo associou-se positivamente ao Eu detestado, que foi seu preditor. O Comprometimento Normativo associou-se de forma positiva ao Eu detestado, Autocriticismo total e idade negativamente ao Mindfulness. A idade foi o seu preditor. O Comprometimento Afetivo associou-se positivamente aos meses de trabalho na instituição, que foram seus preditores. Os cuidadores com um familiar com deficiência mental tiveram um valor mais baixo de Eu inadequado. Discussão: No geral, esta amostra de cuidadores formais apresentou caraterísticas psicológicas que nos tranquilizam quanto ao papel que desempenham junto de pessoas com doença/deficiência mental, mas as instituições devem sempre encontrar formas de estimular os níveis de comprometimento e autocompaixão dos seus profissionais. / Introduction: Some international and national studies have focused on studying the psychological characteristics of professionals/caregivers working with people with mental disease and intelectual disability. However, to our knowledge, the studies exploring levels of selfcriticism, self-compassion and organizational commitment in these professionals are scarce or even nonexistent. Our goals were to: characterize a sample of formal caregivers/professionals who work with people with mental illness and intellectual in different sociodemographic and professional variables; analyze the levels of selfcriticism, self-compassion and organizational commitment of these formal caregivers/professionals, as well as explore the associations between all these variables (with each other and with the sociodemographic and professional variables and professionals). Methodology: 55 caregivers of people with mental disease/intelectual disability (female/n = 49, 84.5%; mean age of 45,21; DP = 10,92; variation = 22-65) completed a sociodemographic questionnaire, the Organizational Commitment questionnaire, the Forms of Self Criticism Rating Scale and the Self- Compassion Scale. Results: Inadequate Self had na higher mean value than the Hated Self. The mean value of the Reassuring Self was higher than any dimension of selfcriticism. Self-Kindness was the one with a higher mean value (of self-compassion) and Self-Judjment the one with the lowest mean value. The Inadequate Self and the Hated Self were positively associated with the negative dimensions of selfcompassion and the Reassuring Self with the positive dimensions of selfcompassion. The Affective Commitment was positively associated to total selfcriticism. The Continuance Commitment was associated with the Hated Self (positively), being its predictor. The Normative Commitment was positively associated to the Hated Self, the total selfcriticism and age and negatively to Mindfulness. Age was its predictor. The Affective Commitment was positively associated to months of work at the institution. This variable was its predictor. Professionals with a family member with intellectual disability had a lower value of Inadequate Self. Discussion: In general, this sample of formal caregivers presented psychological characteristics that reassure us about the role that they have while working with people with mental disease/intellectual disability, but the institutions must always find ways of stimulating the commitment and selfcompassion levels of their professionals.

Introdução: A presença do diagnóstico de autismo numa criança é algo marcante no seio familiar. Implica inúmeros desafios para os seus pais/progenitores, podendo influenciar os objetivos delineados para as suas vidas e a satisfação na relação conjugal. Os nossos objetivos foram: caraterizar progenitores de crianças com autismo quanto aos objetivos de vida e satisfação na vida conjugal e explorar as associações existentes entre estas duas variáveis (e com variáveis sociodemográficas e relativas ao apoio recebido). Não deixamos de explorar os níveis de depressão, ansiedade, e stress, vivenciados por estes pais. Metodologia: 66 progenitores (sexo feminino, n = 52, 78,8%; idade média, M = 40,2, DP = 6,45) de crianças com autismo preencheram um questionário sociodemográfico, o Teste dos objetivos de vida/PIL-R, a Escala de Avaliação da Satisfação em Áreas da Vida Conjugal/EASAVIC e a Depression, Anxiety and Stress Scale-21/DASS-21. Resultados: Os progenitores revelaram valores médios de objetivos de vida (PIL-R). Foi na dimensão vivencial (PIL-R) e nas dimensões Comunicação e Intimidade Emocional (satisfação em áreas da vida conjugal/EASAVIC) que os progenitores apresentaram valores médios mais elevados. No caso da DASS-21, foi na escala Stress que os progenitores apresentaram valores mais elevados. Porém, em todas as dimensões da DASS-21, os níveis encontrados foram normais. Não se verificaram diferenças estatisticamente significativas por sexo em todas as dimensões do PIL-R, da EASAVIC e DASS-21. Ambas as dimensões do PIL-R, dimensional e existencial, bem como a sua pontuação total mostraram estar associadas com todas as dimensões da EASAVIC (satisfação em áreas da vida conjugal). As três dimensões da DASS-21 (Depressão, Ansiedade e Stress) revelaram estar associada (negativamente) com praticamente todas as dimensões da EASAVIC e do PIL-R. Os progenitores que pertenciam a associações de apoio apenas se diferenciaram dos progenitores que pertenciam a um grupo (de apoio e partilha) numa rede social na dimensão Ansiedade, com estes últimos a apresentarem um nível mais elevado. Discussão: Neste estudo (ainda que numa amostra de tamanho reduzido), inovador pelo tema explorado, os níveis dos objetivos de vida e de satisfação em áreas da vida conjugal (bem como de sintomas de psicopatologia) pareceram “não sofrer” o impacto associado ao facto dos progenitores terem um filho com autismo. Os objetivos de vida mantidos por estes pais influenciam a sua satisfação com a vida conjugal e vice-versa, indicando a importância das equipas que trabalham com estes pais não esquecerem a promoção destas variáveis. / Introduction: The presence of the diagnosis of autism in a child is something remarkable in the family. Involves many challenges for parents/progenitors, which can influence the goals they define in their lives and their satisfaction with the marital relationship. Our objectives were to characterize parents of children with autism on the objectives of life and satisfaction with marital life and explore the associations between these two variables (and with sociodemographic and support variables). We will not forget to explore the levels of depression, anxiety, and stress, experienced by these parents. Methodology: 66 parents (females, n = 52, 78.8%, mean age, M = 40.2, SD = 6.45) of children with autism completed a sociodemographic questionnaire, the Test of Life Goals/PIL-R, the Areas of Marital Satisfaction Rating Scale/EASAVIC and the Depression, Anxiety and Stress Scale-21/DASS-21. Results: Parents showed a mean value of life goals (PIL-R). Was in the experiential dimension (PIL-R) and the Communication and Emotional Intimacy dimensions (satisfaction in areas of marital life/EASAVIC) that the parents presented higher mean values. Regarding DASS-21, Stress was the scale in which the parents had higher values. However, in all the DASS-21, levels were “normal”. There were no statistically significant differences by gender in all the PIL-R, EASAVIC and DASS-21 scales. Both dimensions of the PIL-R, dimensional and existential, as well as the total score were found to be associated with all the dimensions of EASAVIC (satisfaction in areas of marital life). The three dimensions of the DASS-21 (Depression, Anxiety and Stress) revealed to be associated (negatively) with virtually all dimensions of the EASAVIC and the PIL-R. Parents who belonged to associations only differed from the parents from a social network group (of support and sharing) in the anxiety dimension, with the later presenting an higher level. Discussion: In this study (even if in a small sample size), innovative by the theme explored, levels of life goals and satisfaction in areas of marital life (as well as symptoms of psychopathology) seemed not to suffer from the impact of the parents having a child with autism. The life goals held by these parents influence their satisfaction with marital life and vice versa, indicating the importance of teams working with these parents of not forgetting the promotion of these variables.

Entrepreneurs are individuals who can transform economic and social realities by promoting development, so it became important tools in generating externalities in regions where they operate. In Brazil, 59.9% of new ventures do not reach the fourth year of life, the mortality rate of new ventures is high. The causes of mortality are numerous, and within the behavioral aspects, one is the locus of control. This study determines the degree of association between internal locus of control and achieving business success of entrepreneurs in Rio Grande do Norte who participated in the workshop EMPRETEC. The approach that studies the behavior entrepreneurs agreed that there are psychological characteristics associated with a set of values, attitudes and needs that determine the behavior and induce the entrepreneur to achieve success. Among these features is the locus of control, a skill that individuals must identify in their actions, or lack of them, the causes of their successes and failures. The locus is external when the individual attributes to factors outside themselves as causes of their results, and is built in when you can identify the actions that led to success. We surveyed 223 entrepreneurs statewide who answered the questionnaire for assessing the scale of locus of control, selfassessment questionnaire of entrepreneurial characteristics of EMPRETEC and a questionnaire assessing the business success. 71.9% were identified as having success. Among the behavioral characteristics strongest in the group of entrepreneurs are setting goals and commitment. Was found for locus of control mean value of 7.35, confidence interval between 7.05 and 7.66. Showing that the locus of control group is predominantly internal. We also found a correlation between the locus and commitment, between setting goals and commitment; calculated risks and information search; search of information and commitment, and between commitment and independence and self confidence. Dependence was not identified among the set of features and business success, determining the absence of an ideal profile. However, logistic regression significant association was found indicating that the smaller the individual's locus of control increased the likelihood of it achieving business success

Aflatoxin B1 (AFB1) is a secondary metabolite produced by the fungi Aspergillus flavus and is the most potent hepatocarcinogen known in mammals and has been classified by the International Agency of Research on Cancer as Group 1 carcinogen. Although dietary exposure to AFB1 has been extensively documented, there are still few studies dedicated to the problem of occupational exposure. Considering recent findings regarding AFB1 occupational exposure in poultry production, it was considered relevant to clarify if there is also exposure in poultry slaughterhouses. Occupational exposure assessment to AFB1 was done with a biomarker of internal dose that measures AFB1 in the serum by enzyme-linked immunosorbent assay. Thirty workers from a slaughterhouse were enrolled in this study. A control group (n = 30) was also considered in order to know AFB1 background levels for Portuguese population. Fourteen workers (47.0%) showed detectable levels of AFB1 with values from 1.06 to 4.03ng ml(-1), with a mean value of 1.73ng ml(-1). No AFB1 was detected in serum of individuals used as controls. Despite uncertainties regarding the exposure route that is contributing more to exposure (inhalation or dermal) is possible to state that exposure to AFB1 is occurring in the slaughterhouse studied. It seems that reducing AFB1 contamination in poultry production can have a positive result in this occupational setting.

This thesis examines the spatial and temporal variation in nitrogen dioxide (NO2) levels in Guernsey and the impacts on pre-existing asthmatics. Whilst air quality in Guernsey is generally good, the levels of NO2 exceed UK standards in several locations. The evidence indicates that people suffering from asthma have exacerbation of their symptoms if exposed to elevated levels of air pollutants including NO2, although this research has never been carried out in Guernsey before. In addition, exposure assessment of individuals is rarely carried out and research in this area is limited due to the complexity of undertaking such a study, which will include a combination of exposures in the home, the workplace and ambient exposures, which vary depending on the individual daily experience. For the first time in Guernsey, this research has examined NO2 levels in correlation with asthma patient admissions to hospital, assessment of NO2 exposures in typical homes and typical workplaces in Guernsey. The data showed a temporal correlation between NO2 levels and the number of hospital admissions and the trend from 2008-2012 was upwards. Statistical analysis of the data did not show a significant linear correlation due to the small size of the data sets. Exposure assessment of individuals showed a spatial variation in exposures in Guernsey and assessment in indoor environments showed that real-time analysis of NO2 levels needs to be undertaken if indoor micro environments for NO2 are the be assessed adequately. There was temporal and spatial variation in NO2 concentrations measured using diffusion tubes, which provide a monthly mean value, and analysers measuring NO2 concentrations in real time. The research shows that building layout and design are important factors for good air flow and ventilation and the dispersion of NO2 indoors. Environmental Health Officers have statutory responsibilities for ambient air quality, hygiene of buildings and workplace environments and this role needs to be co-ordinated with healthcare professionals to improve health outcomes for asthmatics. The outcome of the thesis was the development of a risk management framework for pre-existing asthmatics at work for use by regulators of workplaces and an information leaflet to assist in improving health outcomes for asthmatics in Guernsey.

Layered structures, known as micro structures in marine environments are common features of which their formation mechanisms are first reviewed. Some methods of measuring such features based on the measurements and theories are presented for the Persian Gulf. This includes determination of layers with temperature inversion (TI) associated with double diffusive convection (DDC). The relevant associated parameters are estimated from ROPME CTD data for late winter and early summer of 1992. Only in certain parts temperature inversion and DDC are observed which seem to produce layered structures. Observations show that the places with TI and DDC are mainly confined to the frontal regions where the water entering the Persian Gulf and water exiting it meet, nearly along the axis of the Gulf. TI and DDC is mainly observer in the northern bound of the front. Typical density ratio for regions with TI and DDC is 0.7 to 0.2 and the mean depth is at about 37 ± 3 m for the Persian Gulf. TI and DDC are also found in the outflow from the Persian Gulf to the Oman Gulf which is found to be at a depth of about 250 m. Horizontal addiction and reduction of solar heating seem to be the main reasons in producing layers with TI and DDC. It is also found that the regime of DDC in the Persian Gulf is more diffusive and the flow associated with intrusion layers with TI is non-isopycnal (more unstable). However for the Oman sea both diffusive and finger regime are observed and the flow is inferred to be isopycnal (more stable statically). Typical heat and salt fluxes due to DDC are found to be 6 W/m2 and 0.36 W/m2 respectively. Effective salinity diffusivity, Ks and heat diffusivity, Kr have been estimated for the places with DDC in the Persian Gulf and Oman Gulf (Ks=1.1 *10-7 m2/s, KT= 1.88*10-6 m2/s). Their values are within the values obtained by others. The buoyancy frequency for the Persian Gulf with typical mean value of 0.05s-1 is much higher than these of the free Oceans. Such large values of N (typically 0.05 s-1) indicate that processes such as tide can produce strong internal waves which may be another factor in producing layered structures. This requires separate study.

It is important to evaluate the quality of water for proper management of these resources, since the increase of environmental degradation and the multiple use of water resources are decreasing the quality of water consumed by living beings. The objective of this study was to characterize the phytoplankton community and its variations during periods of dray and rain in Jiqui Lake located in Parnamirim, RN. It was also aimed to analyze the physical and chemical factors of this environment, in order to contribute to the knowledge of water quality used for human consumption. The collection of water samples were carried out in September 2008 to August 2009. The collection of the phytoplankton community was carried out in four sampling sites (surface, bottom, margin of the lake without macrophytes and site dominated by macrophytes). Phytoplankton was collected using plankton net of 20m. The analysis of nutrients and identification of phytoplankton were performed in the laboratory. The results indicate that concentration of chlorophyll a was high in the bottom with mean value of 1.07 μgL-1 (SD ± 1.61). During the study period there was a dominance of the following species: Euglena gracilis, Trachelomonas sp, Cyclotellas sp, Gomphonema apuncto, Navicula cuspidata var. cuspidata, Navicula sp, Rhopalodia gibba. There was homogeneity between limnological values in the four study sites, with significant difference between the periods of drought and rain. The Jiqui Lake is considered oligotrophic due to its low concentrations of chlorophyll a, high transparency and low levels of nutrients. The values of BOD and chlorophyll a concentration remained below the permitted standards existing for freshwaters in Brazil, thus the water from Lake Jiqui is of good quality, suitable for human consumption.

Observations of H3+ in the Galactic diffuse interstellar medium (ISM) have led to various surprising results, including the conclusion that the cosmic-ray ionization rate (zeta_2) is about 1 order of magnitude larger than previously thought. The present survey expands the sample of diffuse cloud sight lines with H3+ observations to 50, with detections in 21 of those. Ionization rates inferred from these detections are in the range (1.7+-1.0)x10^-16 s^-1 < zeta_2 < (10.6+-6.8)x10^-16 s^-1 with a mean value of zeta_2=(3.3+-0.4)x10^-16 s^-1. Upper limits (3sigma) derived from non-detections of H3+ are as low as zeta_2 < 0.4x10^-16 s^-1. These low upper-limits, in combination with the wide range of inferred cosmic-ray ionization rates, indicate variations in zeta_2 between different diffuse cloud sight lines. Calculations of the cosmic-ray ionization rate from theoretical cosmic-ray spectra require a large flux of low-energy (MeV) particles to reproduce values inferred from observations. Given the relatively short range of low-energy cosmic rays --- those most efficient at ionization --- the proximity of a cloud to a site of particle acceleration may set its ionization rate. Variations in zeta_2 are thus likely due to variations in the cosmic-ray spectrum at low energies resulting from the effects of particle propagation. To test this theory, H3+ was observed in sight lines passing through diffuse molecular clouds known to be interacting with the supernova remnant IC 443, a probable site of particle acceleration. Where H3+ is detected, ionization rates of zeta_2=(20+-10)x10^-16 s^-1 are inferred, higher than for any other diffuse cloud. These results support both the concept that supernova remnants act as particle accelerators, and the hypothesis that propagation effects are responsible for causing spatial variations in the cosmic-ray spectrum and ionization rate. Future observations of H3+ near other supernova remnants and in sight lines where complementary ionization tracers (OH+, H2O+, H3O+) have been observed will further our understanding of the subject.

Small pelagic fishes are known to respond rapidly to changes in ocean climate. In this study, we evaluate the effects of future environmental warming (+2°C) during the early ontogeny of the European sardine, Sardina pilchardus. Warming reduced the survival of 30-day-old larvae by half. Length at hatching increased with temperature as expected, but no significant effect was observed on the length and growth at 30 days post-hatching. Warming did not significantly affect the thermal tolerance of sardine larvae, even though the mean lethal temperature increased by 1°C. In the warm conditions, sardine larvae showed signs of thermal stress, indicated by a pronounced increase in larval metabolism (Q 10 = 7.9) and a 45% increase in the heat shock response. Lipid peroxidation was not significantly affected by the higher temperature, even though the mean value doubled. Warming did not affect the time larvae spent swimming, but decreased by 36% the frequency of prey attacks. Given the key role of these small pelagics in the trophic dynamics off the Western Iberian upwelling ecosystem, the negative effects of warming on the early stages may have important implications for fish recruitment and ecosystem structure.

Background: Celiac disease (CD) has a negative impact on the health-related quality of life (HRQL) of affected patients. Although HRQL and its determinants have been examined in Spanish CD patients specifically recruited in hospital settings, these aspects of CD have not been assessed among the general Spanish population. Methods: An observational, cross-sectional study of a non-randomized, representative sample of adult celiac patients throughout all of Spain's Autonomous Regions. Subjects were recruited through celiac patient associations. A Spanish version of the self-administered Celiac Disease-Quality of Life (CD-QOL) questionnaire was used. Determinant factors of HRQL were assessed with the aid of multivariate analysis to control for confounding factors. Results: We analyzed the responses provided by 1,230 patients, 1,092 (89.2%) of whom were women. The overall mean value for the CD-QOL index was 56.3 ± 18.27 points. The dimension that obtained the most points was dysphoria, with 81.3 ± 19.56 points, followed by limitations with 52.3 ± 23.43 points; health problems, with 51.6 ± 26.08 points, and inadequate treatment, with 36.1 ± 21.18 points. Patient age and sex, along with time to diagnosis, and length of time on a gluten-free diet were all independent determinant factors of certain dimensions of HRQL: women aged 31 to 40 expressed poorer HRQL while time to diagnosis and length of time on a gluten-free diet were determinant factors for better HRQL scores. Conclusions: The HRQL level of adult Spanish celiac subjects is moderate, improving with the length of time patients remain on a gluten-free diet.

The Brazil is the third largest producer of cashew nuts in the world. Despite the social and economic importance of the cashew nut, its production is still carried out artisanally. One of the main problems encountered in the cashew production chain are the conditions under which the roasting of the nut occurs to obtain the kernel from the shell. In the present study was conducted a biomonitoring of the genotoxic and cytotoxicity effects associated with the elements from the cashew nut roasting in João Câmara - RN, semi-arid region of Brazil. To assess the genotoxic was used the bioassay of micronucleus (MN) in Tradescantia pallida. In addition, it was performed a comparative between the Tradescantia pallida and KU-20 and other biomarkers of DNA damage, such as the nucleoplasmic bridges (NBP) and nuclear fragments (NF) were quantified. The levels of particulate matter (PM1.0, PM2.5, PM10) and black carbon (BC) were also measured and the inorganic chemical composition of the PM2.5 collected was determined using X-ray fluorescence spectrometry analysis and the assessment of the cytotoxicity by MTT assay and exclusion method by trypan blue. . For this purpose, were chosen: the Amarelão community where the roasting occurs and the Santa Luzia farm an area without influence of this process. The mean value of PM2.5 (Jan 2124.2 μg/m3; May 1022.2 μg/m3; Sep 1291.9 μg/m3) and BC (Jan 363.6 μg/m3; May 70.0 μg/m3; Sep 69.4 μg/m3) as well as the concentration of the elements Al, Si, P, S, Cl, K, Ca, Ti, Cr, Mn, Fe, Ni, Cu, Zn, Se, Br and Pb obtained at Amarelão was significantly higher than at Santa Luzia farm. The genotoxicity tests with T. pallida indicated a significant increase in the number of MN, NBP and NF and it was found a negative correlation between the frequency of these biomarkers and the rainfall. The concentrations of 200 μg/mL and 400 μg/mL of PM2.5 were cytotoxic to MRC-5 cells. All together, the results indicated genotoxicity and citotoxicity for the community of Amarelão, and the high rates of PM2.5 considered a potential contributor to this effect, mainly by the high presence of transition metals, especially Fe, Ni, Cu, Cr and Zn, these elements have the potential to cause DNA damage. Other nuclear alterations, such as the NPBs and NFs may be used as effective biomarkers of DNA damage in tetrads of Tradescantia pallida. The results of this study enabled the identification of a serious occupational problem. Accordingly, preventative measures and better practices should be adopted to improve both the activity and the quality of life of the population. These measures are of fundamental importance for the sustainable development of this activity.

Background: Non-alcoholic steatohepatitis (NASH) is a chronic liver disease that is capable of progressing to end-stage liver disease, but generally has a benign course. Non-alcoholic steatohepatitis (NASH) is a growing public health problem with no approved therapy. NASH projected to be the leading cause of liver transplantation in the United States by 2020. Obesity, non-insulin-dependent diabetes mellitus and hyperlipidaemia are the most common associations of the disease. Global prevalence of NASH is 10-24% amongst general population but increases to 25-75% in obese diabetic individuals. Objective: There is an urgent need for efficient therapeutic options as there is still no approved medication. The aim of this study was to detect changes in biochemical parameters including insulin resistance, cytokines, blood lipid profile and liver enzymes following weight loss in patients with non-alcoholic steatohepatitis. Materials and methods: One hundred obese patients with NASH, their age between 35-50 years, body mass index (BMI) from 30 to 35 Kg/m2 were included in the study in two subgroups; the first group (A) received moderate aerobic exercise training in addition to diet regimen , where the second group (B) received no treatment intervention. Results: The mean values of leptin, TNF-α, IL6, IL8, Alanine Aminotransferase (ALT), Aspartate Aminotransferase (AST), Homeostasis Model Assessment-Insulin Resistance- index (HOMA-IR), Total Cholesterol (TC), Low Density Lipoprotein Cholesterol (LDL-c) , Triglycerides (TG) and BMI were significantly decreased in group (A), where the mean value of Adiponectin and High Density Lipoprotein Cholesterol (HDL-c) were significantly increased, while there were no significant changes in group (B). Also, there was a significant difference between both groups at the end of the study. Conclusion: Weight loss modulates insulin resistance, adiponectin, leptin, inflammatory cytokine levels and markers of hepatic function in patients with nonalcoholic steatohepatitis.

Toxic metals are part of the most important groups of environmental pollutants that can bind to vital cellular components and interfere with their functions via inhalation, foods, water etc. The serum levels of toxic metals (lead, mercury, cadmium and arsenic) in pregnant women with history of pregnancy complications, pregnant women without history of pregnancy complication and non-pregnant women in Benin City, South – South Nigeria was investigated in this paper, with total of 135 healthy women comprising of 45 pregnant women with history of previous pregnancy complications, 45 pregnant women without history of pregnancy complications and 45 non-pregnant women without history of pregnancy complications (controls). Some demographic characteristics and 4ml of blood samples were obtained from each subject for the analysis of lead, mercury, cadmium and arsenic by standard methods. Pregnant women with history of pregnancy complications recorded a highly significant increase in the toxic metal (lead) mean value of 25.81μg/dl as against 23.70μg/dl for pregnant women without history of pregnancy complications and 11.23μg/dl for non-pregnant (control) women without history of pregnancy complications as well as significant increases in the mean values of other toxic metals (mercury, cadmium and arsenic) compared with controls (p<0.001). The selected toxic metals (Pb, Hg, Cd and As) may be involved in the development of pregnancy complications among pregnant women in Benin City, South– South Nigeria. Lead in particular may pose threat to mothers and fetuses as its mean values in the two groups of pregnant women were well above normal.
