RESUMO
Helicobacter pylori (HP) is a vital element in the etiology of peptic ulcers and gastric cancer. This research aimed to determine the frequency, distribution, and determinants of HP infection in adults and adolescents with gastric symptoms in district Haripur, Khyber Pakhtunkhwa, Pakistan. This cross-sectional study was performed from June 2018 to June 2020 at the Medical Laboratory Technology Department, The University of Haripur, Pakistan. Presence of HP was a research variable, while sex, age groups, education status, overcrowding, dining habits, milk intake, drinking water source and animal contact were grouping variables. Immuno-chromatographic technique (ICT) was used to for serological detection of HP antibodies. All variables were represented by frequency and percentage with 95%CI. Prevalence of HP and its distribution by eight socio-demographic variables was testified by the chi-square goodness-of-fit test while association was testified by chi-square test of association. Out of total 1160 cases, 557 (48%) were positive for HP. Population prevalence was higher in men, in the age group 20-40 years, illiterate, family size ≤ 10 persons, taking restaurant food, using tetra pack, using municipal water, and having animal contact. The observed prevalence of HP was similar to its expected prevalence in the population. The observed distribution of HP in the sample was different from its expected distribution in population by eight socio-demographic variables. Presence of HP was associated with all eight socio-demographic variables besides age groups.
Helicobacter pylori (HP) é um elemento vital na etiologia de úlceras pépticas e câncer gástrico. Esta pesquisa teve como objetivo determinar a frequência, distribuição e determinantes da infecção por HP em adultos e adolescentes com sintomas gástricos no distrito de Haripur, Khyber Pakhtunkhwa, Paquistão. Este estudo transversal foi realizado de junho de 2018 a junho de 2020 no Departamento de Tecnologia de Laboratórios Médicos da Universidade de Haripur, Paquistão. A presença de HP foi uma variável de pesquisa, enquanto sexo, faixas etárias, escolaridade, superlotação, hábitos alimentares, ingestão de leite, fonte de água potável e contato com animais foram variáveis ââde agrupamento. A técnica imunocromatográfica (TIC) foi utilizada para a detecção sorológica de anticorpos para HP. Todas as variáveis ââforam representadas por frequência e percentual com IC 95%. A prevalência de HP e sua distribuição por oito variáveis ââsociodemográficas foi comprovada pelo teste de ajuste do qui-quadrado, enquanto a associação foi verificada pelo teste de associação do qui-quadrado. Do total de 1.160 casos, 557 (48%) foram positivos para HP. A prevalência populacional foi maior em homens, na faixa etária de 20 a 40 anos, analfabetos, família ≤ 10 pessoas, consumindo comida de restaurante, usando tetra pack, usando água municipal e tendo contato com animais. A prevalência observada de HP foi semelhante à sua prevalência esperada na população. A distribuição observada de HP na amostra foi diferente de sua distribuição esperada na população por oito variáveis ââsociodemográficas. A presença de HP foi associada a todas as oito variáveis ââsociodemográficas além das faixas etárias.

The survival, feeding response, and detoxification mechanism of Rhynchophorus ferrugineus Olivier, a key pest responsible for destruction of date palm, was examined with different extracts of Piper nigrum and its major constituent (piperine) identified by GC-MS. In the present study, toxicity of different extracts of black pepper was evaluated by incorporating diffferent doses of extracts into the artificial diet of red palm weevil larvae. All extracts showed dose-dependent insecticidal activity to the tested eighth-instar red palm weevil larvae. Among all the extracts, maximum larvicidal activity was exhibited by chloroform (LD50 = 342.62 mg/l), followed by dichloromethane (LD50 = 357.78 mg/l), acetone (LD50 = 372.57 mg/l), and ethanol (LD50 = 408.88 mg/l). However, piperine, a major constituent of all black pepper extracts identified by GC-MS in the present work, was found to be the most potent treatment exhibiting the least LD50 (219.88 mg/l). In addition, nutritional indices evaluated by calculating the efficiency of the conversion of ingested food (ECI) and digested food (ECD) at the same dose (219.88 mg/l) showed that there was maximum reduction in the ECI (49.90%) and ECD (62.21%) index of larvae fed diets incorporated with piperine. Larvae that were fed diets incorporated with different black pepper extracts experienced increases in the expression of detoxification genes (glutathione S-transferase and cytochrome P450), and this upregulation in detoxification genes (glutathione S-transferase, cytochrome P450 and esterase) was tremendously high in larvae fed diets incorporated with piperine. Results suggest that piperine is a promising bio-pesticide agent for the control of R. ferrugineus Olivier.

Methanolic extracts of different parts of five medicinal plants, Ferula assafoetidaL. resin, Grewia asiaticaL. leaves, Ipomoea hederaceaJacq. seeds, Lepidium sativumL. seeds and Terminalia chebulaRetz. fruits were tested in vitrofor their cytotoxic, phytotoxic, insecticidal, nematicidal and anthelmintic activities. Ipomoea hederaceashowed very significant phytotoxic and cytotoxic activity, with 100% inhibition of Lemna minorgrowth and 100% death of Artemia salinaat concentrations of 1000 and 100 µg mL-1. Grewia asiaticaexhibited very weak activities while Lepidium sativumand Ferula assafoetidashowed moderate to good potential in all three bioassays. The results suggest screening of Ipomoea hederaceaseeds further for isolation of bioactive compounds that may be responsible for its toxic potential.
