Proanthocyanidins (PA) in Senna alata leaves were investigated by thiolysis with benzyl mercaptan, LC–MS and NMR and consisted of almost pure propelargonidins with 94%) and epicatechin a minor constituent (6.4%) in residual PA and mainly detected as an extension unit

Novel Decapeptides that Bind Avidly and Deliver Radioisotope to Colon Cancer Cells

The rapidly growing field of targeted tumor therapy often utilizes an antibody, sometimes tagged with a tumor-ablating material such as radioisotope, directed against a specific molecule.This report describes the discovery of nine novel decapeptides which can be radioactively labeled, bind to, and deliver (32)P to colon cancer cells. The decapeptides vary from one another by one to three amino acids and demonstrate vastly different binding abilities. The most avidly binding decapeptide can permanently deliver very high levels of radioisotope to the adenocarcinoma cancer cell lines at an efficiency 35 to 150 times greater than to a variety of other cell types, including cell lines derived from other types of cancer or from normal tissue.This experimental approach represents a new example of a strategy, termed peptide binding therapy, for the potential treatment of colorectal and other adenocarcinomas

Cardiovascular disease prevention in rural Nigeria in the context of a community based health insurance scheme: QUality Improvement Cardiovascular care Kwara-I (QUICK-I)

Background: Cardiovascular diseases (CVD) are a leading contributor to the burden of disease in low- and middle-income countries. Guidelines for CVD prevention care in low resource settings have been developed but little information is available on strategies to implement this care. A community health insurance program might be used to improve patients' access to care. The operational research project "QUality Improvement Cardiovascular care Kwara - I (QUICK-I)" aims to assess the feasibility of CVD prevention care in rural Nigeria, according to international guidelines, in the context of a community based health insurance scheme. Methods/Design. Design: prospective observational hospital based cohort study. Setting: a primary health care centre in rural Nigeria. Study population: 300 patients at risk for development of CVD (patients with hypertension, diabetes, renal disease or established CVD) who are enrolled in the Hygeia Community Health Plan. Measurements: demographic and socio- economic data, physical and laboratory examination, CVD risk profile including screening for target organ damage. Measurements will be done at 3 month intervals during 1 year. Direct and indirect costs of CVD prevention care will be estimated. Outcomes: 1) The adjusted cardiovascular quality of care indicator scores based on the "United Kingdom

Better mental health in children of Vietnamese refugees compared with their Norwegian peers - a matter of cultural difference?

<p>Abstract</p> <p>Background</p> <p>There are conflicting results on whether immigrant children are at a heightened risk of mental health problems compared with native youth in the resettlement country.</p> <p>The objective of the study</p> <p>To compare the mental health of 94 Norwegian-born children from a community cohort of Vietnamese refugees, aged 4 - 18 years, with that of a Norwegian community sample.</p> <p>Methods</p> <p>The SDQ was completed by two types of informants; the children's self-reports, and the parents' reports, for comparison with Norwegian data from the Health Profiles for Children and Youth in the Akershus study.</p> <p>Results</p> <p>The self-perceived mental health of second-generation Vietnamese in Norway was better than that of their Norwegian compatriots, as assessed by the SDQ. In the Norwegian-Vietnamese group, both children and parents reported a higher level of functioning.</p> <p>Conclusion</p> <p>This surprising finding may result from the lower prevalence of mental distress in Norwegian-Vietnamese children compared with their Norwegian peers, or from biased reports and cultural differences in reporting emotional and behavioural problems. These findings may represent the positive results of the children's bi-cultural competencies.</p

Relationship between Unhealthy Sexual Behaviour and Urinary Infections among Adolescents Presenting in a Tertiary Hospital in South West Nigeria

Adolescent is an important segment of the world population accounting for about one fifth. It is a transition state between childhood and adulthood and characterized with the development of behaviours with lifelong consequences. Such behaviours include unhealthy sexual practices with its associated risks like unwanted pregnancy and sexually transmitted diseases. This was a cross sectional descriptive study of 321 adolescents who presented at the general outpatient clinic of a tertiary health institution. The diagnosis of urinary infection was by the use of rapid dipstick test to detect the presence of nitrites, while the presence of pus cells, white blood cells greater than 5 per high power fluid, epithelial cells and trichomonal vaginalis were identified microscopically. Their HIV status was also determined. The fifty three (16.25) of the respondents who had coital experience were screened for evidence of urinary infection. The prevalence of urinary infection was 24.5% among the respondents with 10% and 5% of the sexually exposed females reported homosexual and bisexual experience. Parental higher socioeconomic class was protective against sexual exposure among the adolescents. In view of the high level of poverty with a large part of the population belonging to low socioeconomic class, it is necessary to research into possible interventional study on how to prevent unhealthy sexual behavior among adolescents from low socioeconomic class.Key words: sexual behavior; Urogenital Infection; Adolescent

Paternal predictors of the mental health of children of Vietnamese refugees

Background: Intergenerational transmission of trauma as a determinant of mental health has been studied in the offspring of Holocaust survivors and combat veterans, and in refugee families. Mainly negative effects on the children are reported, while a few studies also describe resilience and a possible positive transformation process. A longitudinal prospective cohort study of Vietnamese refugees arriving in Norway in 1982 reports a 23 years followup, including spouses and children born in Norway, to study the long-term effects of trauma, flight, and exile on the offspring of the refugees. Objectives of the study: 1. To study the association between the psychological distress of Vietnamese refugee parents and their children after 23 years resettlement. 2. To analyse paternal predictors for their children’s mental health. Methods: Information from one or both parents at arrival in 1982 (T1), at follow-up in 1985 (T2), and 23 years after arrival (T3) was included. The mental health was assessed by the Global Severity Index (GSI) of the self-report Symptom Check List-90-R (SCL-90-R) for parents (n = 88) and older children (age 19-23 yrs, n = 12), while children aged 4-18 (n = 94) were assessed using the Strengths and Difficulties Questionnaire (SDQ). Results: Thirty percent of the families had one parent with a high psychological distress score ("probable caseness” for a mental disorder), while only 4% of the children aged 10 - 23 years were considered as probable cases. In spite of this, there was an association between probable caseness in children and in fathers at T3. A significant negative paternal predictor for the children’s mental health at T3 was the father’s PTSD at arrival in Norway, while a positive predictor was the father’s participation in a Norwegian network three years after arrival. Conclusions: Children of refugees cannot be globally considered at risk for mental health problems. However, the preceding PTSD in their fathers may constitute a specific risk for them.publishedVersio

Oxidative Stress Markers and Genetic Polymorphisms of Glutathione S-Transferase T1, M1, and P1 in a Subset of Children with Autism Spectrum Disorder in Lagos, Nigeria

Background: The role of oxidative stress has been identified in the development of autism spectrum disorder (ASD), and polymorphisms of glutathione S-transferase have been associated with some diseases linked to oxidative stress. Hence, we evaluated the serum levels of oxidative stress markers and investigated genetic polymorphisms of glutathione S-transferase associated with autism. Materials and Methods: Forty-two children clinically diagnosed with ASD using the Diagnostic and Statistical Manual for Mental Disorders (DSM-5) criteria and a clinical interview were included in the study. Twenty-three age-matched controls without any known genetic/developmental disorder were also recruited. Oxidative stress markers along with the genetic polymorphisms of glutathione S-transferase were determined. Results: Reduced glutathione in ASD patients was significantly lower than the control (P = 0.008), whereas other oxidative stress markers measured were not significantly different in both the control and case populations. The frequencies of GSTT1 and GSTM1 null genotypes were lower among the controls compared with the cases, however, no association risk was observed. The observed risk of carrying Val/Val genotype among the cases was approximately six times that of the controls. Conclusion: Individuals with ASD showed a significant diminished level of reduced glutathione, however, the distribution of GSTT1, GSTM1, and GSTP1 polymorphisms was not found to be associated with autism in this study population.Keywords: Autism, genetic polymorphisms, glutathione S-transferase, Nigeria, oxidative stres
