Antidiabetic potential and high synergistic antibacterial activity of silver nanoparticles synthesised with Musa Paradisiaca tepal extract

@#This work investigates the Musa Paradisiaca plant and its tepal extracts. The research findings show that the tepal extracts of M. Paradisiaca contain high phytochemical activity. Hence we can conclude that these plants have a number of beneficial properties. Phytochemical analysis concludes that the plant is rich in flavonoids, phenolic compounds, tannins, terpenoids, and phytosterol. In the current work, silver nanoparticles (AgNPs) have revealed the antioxidant properties of M. Paradisiaca. The results show that the methanolic extracts of these tepals exhibit antioxidant potential and are also sources of natural antioxidant compounds, though comparatively, AgNPs have shown the best antioxidant activity. This work investigates the link between the ethnopharmacological statements and the bioactive constituents found in M. Paradisiaca toward all probable markers for cervical cancer via in vivo studies and molecular docking, to form a pharmacophore setting for the active target. However, most of the mechanisms of action of herbal medicines are not in total agreement, and the information collected from their traditional remedies over the years must not be neglected. Hence, it is sensible to investigate the options available in herbal medicine for cancer progression. Biosynthesised AgNPs are principally spherical and nanosized. It was also found that tepalmediated AgNPs exhibit excellent antimicrobial efficacy against tested human pathogens. This green method can be used as a better alternative source than the chemical fabrication of nanomaterials and the biosynthesised nanoparticles can be used in antibacterial medicines. The methanolictepal extract of M. Paradisiaca with AgNPs displayed proficient antidiabetic properties in the diabetes rat model and so could have a possible development for medical use in the future

Conclusion: Thus B.oleraceavaracephalapossessesanticancer activity against HeLa cell lines.

Comparison of microscopy and PCR for the detection of human Plasmodium species and Plasmodium knowlesi in southern Myanmar

Objectives: To determine the distribution of Plasmodium (P) species including Plas-modium knowlesi and to compare the specificity and sensitivity of microscopy with nested PCR in malaria diagnosis. Methods: The study was conducted in Kawthaung, southern Myanmar. Ninety clinically suspected malaria patients were screened for malaria by Giemsa stained microscopy and confirmed by nested PCR. Results: Among the participants, 57 (63.3％) were positive and 33 (36.7％) were negative by microscopy. Of positive samples, 39 (68.4％) were Plasmodium falciparum, 17 (29.8％) Plasmodium vivax and 1 (1.8％) Plasmodium malariae, whereas 59-amplified by PCR were 40 (67.8％), 18 (30.5％) and 1 (1.7％) respectively. PCR amplified 2 mi-croscopy negative samples. Two samples of P. falciparum detected by microscopy were amplified as P. vivax and vice versa. All samples were negative for Plasmodium ovale, P. knowlesi and mixed infections. Microscopy had a very good measure of agreement (k= 0.95) compared to nested PCR. Sensitivity and specificity of microscopy for diag-nosis of P. falciparum were 92.5％(95％CI:79.6–98.4) and 96.0％(95％CI:86.3–99.5) respectively, whereas for P. vivax were 83.3％(95％CI:58.6–96.4) and 97.2％(95％CI:90.3–99.7). Conclusions: P. knowlesi was not detected by both microscopy and PCR. Giemsa stained microscopy can still be applied as primary method for malaria diagnosis and is considered as gold standard. As to the lower sensitivity of microscopy for vivax malaria, those with previous history of malaria and relapse cases should be diagnosed by RDT or PCR combined with microscopy. Inaccuracy of species diagnosis highlighted the requirement of training and refresher courses for microscopists.

Influencing Factors For Cholera And Diarrhoea: Water Sanitation And Hygiene In Impoverished Rural Villages Of Beluran District, Sabah Malaysia

The lower percentage of water, sanitation and hygiene are the root causes of diarrhoea and cholera. Cholera is a sudden onset of acute watery diarrhoea which can progress to severe dehydration and death if untreated. The current pandemic, Vibrio Cholera O1 started in 1961. This study explores water, sanitation, hygiene and cholera and diarrhoea in three affected villages of Beluran District, Sabah Malaysia to support effective and timely public health intervention. This cross sectional study uses purposive sampling. All (114) households were interviewed and household water samples collected. The study reported lower coverage improved sanitation facilities (35.3% to 52.3%), no latrine at home (37% to 63%), improved water supply (52% to 60%), and prevalence of hand washing after toilet (57% - 74%). For water quality, Ecoli was present in household water (32% to 37%) but Vibrio cholerae was not isolated in any of the water samples tested. Statistically significant associations were found for; 1) occupation−non-agriculture and unimproved sanitation facility and 2) house ownership and correct knowledge of ORS preparation. Predictors for household water quality were: latrine at home, and improved household toilet. Aggressive strategies to improve water supply, sanitation and hygiene−hand washing after toilet−were recommended for future prevention of cholera and diarrhoea in the affected area.

Island Health Review, Progress And The Way Forward In The Western Pacific Region

Island health differs from other health care systems, particularly in that there are limited resources and referral faculties available. With globalisation and climate change, island populations have become increasingly vulnerable to natural disasters and global pandemics. This study will identify, explore, compare and report on island health issues facing in the western Pacific, before making appropriate recommendations. A review of selected health indicators in Pacific islands was collected from the World Health Organization (WHO) and other publicly available resources. In the Pacific region, 15 islands saw lower health expenditure (

Rapid Rural Appraisal of a Rural Village in Sabah

Rapid Rural Appraisal (RRA) is a systematic, semi-structured activity carried out in the field by a multidisciplinary team that is designed to obtain new information and hypotheses about rural life. This article reports the results of an RRA conducted in Kampung Paris 1 (KGP1), Kinabatangan, Sabah under the Annual Health Promotion Program of the School of Medicine, Universiti Malaysia Sabah. A systematic random sampling was used to recruit the villagers and data was obtained through compilation of pre-existing data, field observation, structured interviews with key informants and villagers. Cardiorespiratory diseases were prevalent in KGP1. Common water sources such as rain water collected in dug wells in KGP1 were unhygienic. Dangerous toxic fumes were produced by the burning of municipal wastes nearby village houses. The villagers of KGP1 were exposed to various farm animals, which may harbor zoonoses. Health care services are limited in KGP1. Villagers who were not poor (>RM897) represented 48% of the population, followed by the poor (RM503-897), 20% and the hardcore poor (1.00 person per bedroom. Poor water hygiene, polluted air from open burning, exposure to farm animals, poverty, poor education, overcrowding and inadequate health care services were among the few possible factors affecting the health of villagers in KGP1. Formal rigorous research should be conducted in the future to facilitate specific health interventions in areas of need such as KGP1.

Leptospiral hepatitis in Rangoon General Hospital

A study of 51 patients of acute hepatitis, associated with fever and jaundice, admitted to medical wards in Rangoon General Hospital was performed in 1968. Serological investigation for leptospitosis by using Galton's macroscopic slide agglutination method revealed 18 cases with 4 serogroups of leptospira, viz. L. icterohaemorrhagiae, L. canicola, L. Pomona and L. pyogenes. The epidemiogical aspects of the condition were discussed. Of the 7 cases followed up, 4 patients showed rising titre with L. icterohaemorrhagiae only. Clinical features in these cases were observed. The condition of the diseases in other countries in Southeast Asia was reviewed. Further investigations as to the prevalence of leptospirosis in Burma was suggested.

The clinical and epidemiological observations on viral hepatitis in the Rangoon General Hospital

Periodic assessments on the susceptibility level of some anopheline vectors were carried out at routine catching stations in Kyaukse, Myingyan and Bassein Districts from 1958 up to date. The results obtained indicated that the increase of DDT pressure created bgy prolonged annual application of DDT reduced the susceptibility level of A.culicifacies and developed increased tolerance to DDT. But this species was found to be highly susceptible to dieldrin. Subsequently, the results taken in 1957 revealed that A. culicifacies in Kyaukse area was found to be resistant to DDT. A. sundaicus in a Pyinkhayaing village, Bassein, was still found to be highly susceptible to DDT up to date. The slope, shape and position of regression lines are meaningful in interpreting the changes in the response of mosquitoes to insecticide due to vigour tolerance or physiological resistance. LC50 values may remain close to base-line value in partially resistant heterogeneous strains. But only when resistant individuals approach 40 percent to 50 percent in the whole population, dose the LC50 value of the strain rise noticeably.
