Abstract

Malaria is a hemoparasitosis caused by intracellular protozoa belonging to the genus Plasmodium and transmitted by the bite of femalemosquitoes of the genus Anopheles . A descriptive, cross-sectional study was carried out in the indigenous communities of Bajo Caura,Sucre and Cedeño municipalities, Bolívar state, Venezuela, during the 2015-2016 period. The sample consisted of 244 inhabitants ofthe communities under study. An epidemiological survey was applied to each participant and a blood sample was taken by capillarypuncture, with prior consent and informed settlement. The diagnosis was made by direct parasitological methods of thick blood smearand smear. To relate the presence of malaria and epidemiological variables, the chi-square independence test was applied. Theobserved frequency was 7.0%, all detected cases belong to the Sucre municipality. Female people younger than 10 years of age weremore vulnerable to infection. The species Plasmodium falciparum and Plasmodium vivax were identified, the latter being the mostprevalent. The variables fever, symptomatology associated with malaria, degree of knowledge of the disease and type of housing, wereassociated with infection by Plasmodium spp. Under the conditions of this study it is concluded that, in spite of the results found in theindigenous communities, there is a focus of active malaria transmission. Finally, the information obtained represents a contribution atthe moment of making decisions regarding the components such as surveillance, control and health promotion around malaria.

Abstract

Health professionals are subject to stressful situations almost daily, the current Venezuelan reality means that thesesituations are not limited only to the workplace but even to the daily life of all citizens; In this sense, the successfulresolution of these situations will depend on the subject's own resilience, which will help reduce stress, improvephysical and mental well-being and therefore the quality of service provided. Distribute the professionals according tosocial-labor variables; Determine the levels of resilience. A quantitative, correlational, non-experimental research wascarried out. The population was constituted by the health personnel that worked in the PICU and the sample by 33workers who met the inclusion criteria: more than 6 months working in the PICU. The average age was 38.6 years.More than 80% was female. The highest proportion was married (45.5%) and was from the nursing area (60.6%). Morethan 90% had at least more than 2 years of seniority. 45.5% presented average levels of resilience

Abstract

Physarum polycephalum is a species of slime mold that spends most of its life cycle as a plasmodium, a unicellular multinucleated amoeboid. This species of slime mold is well known for its spatial memory. Oats, quinoa, and barley have a lot of protein and nutrients; therefore, they were used to feed the slime mold. Other studies tested the memory or growth of slime mold. This experiment compared both slime mold growth and memory using oats, quinoa, and barley. It was hypothesized that barley would make the slime mold grow the quickest and largest due to its high protein concentration. Into 3 Petri dishes a culture of slime mold, and each food source was placed. The slime mold was then placed in a shoebox, with graph paper taped to the bottom, to make sure there was minimal lighting. After sections were cut out and placed into the remaining petri dishes with the same food sources it grew in and then placed into a Lego maze with the food sources to track the time of its memory. Barley and oats tied for overall growth after 48-hours, but barley-fed plasmodium grew much faster. It was hypothesized that the maze portion of the experiment, barley fed slime mold, would also complete the maze faster. The hypothesis was not supported. Oat grown slime mold completed the maze the fastest. The slime mold was placed into different mazes and allowed to grow for 48 hours. After 48 hours the hypothesis was concluded to be unsupported.
