Phenolic compound and fatty acid properties of some microalgae species isolated from Erbil City.

The total phenolic compound and fatty acid profiles of lipids from microalgae are unique. The present study was designed to investigate aqueous, ethanolic and acetone extracts of several algae (Spirogyra sp., Spirulina sp.,Chlorella sp and Chara sp.) for their antioxidant capacities of the crude extracts and fractions by radical scavenging activity against the stable radical 1,1-diphenyl-2-picrylhydrazyl DPPH as well; total phenolic content. The results showed that Spirulina sp. indicated significantly higher total phenolic compound and antioxidant activities compared to the other species (P < 0.05) and acetone extracts showed higher quantity among three extracts. The fatty acids analysis using High performance liquid chromatography -HPLC showed the presence of palmitic acid, stearic acid, oleic acid, and linoleic acid, palmitic acid showed high quantity than other fatty acid classes in all studied algae. This study concluded that high antioxidant capacity of microalgae could be inspected for different industrial applications.

Food handlers plays a primary role in the transmission of pathogenically important protozoans and helminth parasites. This study was aimed to evaluate the prevalence of intestinal pathogenic protozoans and helminth parasites among food handlers in and around University of Malakand, Lower Dir, Pakistan. Stool samples were collected from 642 food handlers (all of male) in a cross-sectional study from January to November, 2017. Wet Mount Techniques and concentration methods by using salt and formol­ether solutions. Three hundred and eighty four cases (59.8%) were found infected with one more parasites. Most of the individuals were found infected with helminth (47.6%) as compared to intestinal protozoans (0.93%). Seventy two cases (11.2%) of the cases presented mixed infection with both intestinal protozoan and helminth parasites. The order of prevalence for intestinal helminth was Ancylostoma duodenale (n = 258, 40.1%), followed by Taeniasa ginata (n=96, 14.9%) Ascaris lumbricoides (n = 54, 8.40%) and Trichuris trichura (n=30, 4.60%). For intestinal protozoa, Entamoeba histolytica/díspar (n = 36, 5.64%) was the only protozoan detected. Mono-parasitism was higher than poly-parasitism. Family size income and education level were the factors significantly (P<0.05) associated in the parasites prevalence. Current research showed that IPIs are primarily the foodborne pathogens still an important public health problem in Pakistan. Effective control programs on parasitic diseases transfer and their associated factors are recommended.

Os manipuladores de alimentos desempenham um papel fundamental na transmissão de protozoários e helmintos parasitas patogenicamente importantes. Este estudo teve como objetivo avaliar a prevalência de protozoários patogênicos intestinais e helmintos parasitas entre manipuladores de alimentos na Universidade de Malakand, Lower Dir, Paquistão. Amostras de fezes foram coletadas de 642 manipuladores de alimentos (todos do sexo masculino) em um estudo transversal de janeiro a novembro de 2017. Técnicas de montagem úmida e métodos de concentração usando soluções de sal e formol-éter. Trezentos e oitenta e quatro casos (59,8%) foram encontrados infectados com mais um parasita. A maioria dos indivíduos foi encontrada infectada por helmintos (47,6%) em comparação com protozoários intestinais (0,93%). Setenta e dois casos (11,2%) dos casos apresentavam infecção mista com protozoários intestinais e helmintos parasitas. A ordem de prevalência de helmintos intestinais foi Ancylostoma duodenale (n = 258, 40,1%), seguido por Taeniasa ginata (n = 96, 14,9%) Ascaris lumbricoides (n = 54, 8,40%) e Trichuris trichura (n = 30, 4,60 %). Para protozoários intestinais, Entamoeba histolytica / dispar (n = 36, 5,64%) foi o único protozoário detectado. Monoparasitismo foi maior do que poliparasitismo. A renda familiar e o nível de escolaridade foram os fatores significativamente (P <0,05) associados na prevalência de parasitos. A pesquisa atual mostrou que os IPIs são principalmente os patógenos de origem alimentar, ainda um importante problema de saúde pública no Paquistão. Programas eficazes de controle da transferência de doenças parasitárias e seus fatores associados são recomendados.

Abstract The total phenolic compound and fatty acid profiles of lipids from microalgae are unique. The present study was designed to investigate aqueous, ethanolic and acetone extracts of several algae (Spirogyra sp., Spirulina sp.,Chlorella sp and Chara sp.) for their antioxidant capacities of the crude extracts and fractions by radical scavenging activity against the stable radical 1,1-diphenyl-2-picrylhydrazyl DPPH as well; total phenolic content. The results showed that Spirulina sp. indicated significantly higher total phenolic compound and antioxidant activities compared to the other species (P 0.05) and acetone extracts showed higher quantity among three extracts. The fatty acids analysis using High performance liquid chromatography HPLC showed the presence of palmitic acid, stearic acid, oleic acid, and linoleic acid, palmitic acid showed high quantity than other fatty acid classes in all studied algae. This study concluded that high antioxidant capacity of microalgae could be inspected for different industrial applications.

Resumo O composto fenólico total e os perfis de ácidos graxos dos lipídios das microalgas são únicos. O presente estudo foi desenhado para investigar extratos aquosos, etanólicos e acetona de várias algas (Spirogyra sp., Spirulina sp., Chlorella sp. e Chara sp.) Quanto às suas capacidades antioxidantes dos extratos brutos e frações por atividade de eliminação de radicais contra o radical estável 1,1-difenil-2-picrilhidrazil DPPH também; fenólico total. Os resultados mostraram que a Spirulina sp. indicaram atividade antioxidante e compostos fenólicos totais significativamente maiores em relação às outras espécies (P 0,05), e os extratos de acetona apresentaram maior quantidade entre os três extratos. A análise de ácidos graxos por cromatografia líquida de alta eficiência - HPLC mostrou a presença de ácido palmítico, ácido esteárico, ácido oleico e ácido linoleico; o ácido palmítico apresentou maior quantidade do que outras classes de ácidos graxos em todas as algas estudadas. Este estudo concluiu que a alta capacidade antioxidante pode ser inspecionada para diferentes aplicações industriais.

Clinical characteristics of 110 miliary tuberculosis patients from a low HIV prevalence country.

SETTING: A university teaching hospital in Karachi, Pakistan. OBJECTIVE: To define the clinical characteristics and outcome of miliary tuberculosis (TB) patients from a low human immunodeficiency virus (HIV) prevalence country. DESIGN: Review of adult miliary TB patients admitted between 1994 and 2001. Clinical characteristics of those dying from miliary TB were compared with those of the survivors. RESULTS: Most of the 110 cases reviewed were middle aged or elderly, with a female preponderance. An underlying medical condition was present in 47%. Presenting symptoms were of several weeks' duration, and mostly constitutional (fever and weight loss). Common laboratory findings included anaemia (62%), lymphopaenia (71%), hyponatraemia (74%), elevated serum alkaline phosphatase (57%) and hypoalbuminaemia (92%). Typical miliary pattern was observed in 77% of radiographs. Sputum smear and culture were positive in respectively 36% and 52% of those tested. Biopsy was performed in selected patients. Mean hospital stay was 8.8 days, and mortality was 30%. Those who died were significantly older than survivors and had a more fulminant course. Presence of altered mental status, lung crackles, leucocytosis, thrombocytopaenia and the need for ventilation were associated with increased mortality. CONCLUSION: Miliary TB carries a high mortality. It should be considered in patients who present with prolonged systemic symptoms. A positive TB culture or biopsy is needed to establish a diagnosis.
