|September 15, 2018
Summary
Recent research suggests that Plasmodium vivax malaria relapses stem from liver hypnozoites and bone marrow merozoites. This finding impacts malaria transmission, treatment, and eradication strategies.
Area of Science:
- * Tropical Medicine and Parasitology
- * Infectious Disease Epidemiology
Background:
- * Malaria remains a significant global health challenge, particularly Plasmodium vivax.
- * Understanding relapse mechanisms is crucial for effective disease control.
Purpose of the Study:
- * To investigate the origins of Plasmodium vivax malaria recurrence.
- * To provide evidence supporting specific parasite reservoirs.
Main Methods:
- * Review and synthesis of recent scientific literature.
- * Analysis of data concerning malaria transmission and parasite biology.
Main Results:
- * Evidence supports Plasmodium vivax malaria recurrences originating from liver hypnozoites.
- * Extravascular merozoites in bone marrow are identified as another potential source of relapse.
Conclusions:
- * The dual origin of P. vivax relapse has significant implications for malaria eradication efforts.
- * Current treatment and prevention strategies may need re-evaluation based on these findings.

02:55The Evidence for Evolution
48.3K
Genetic variations accumulating within populations over generations give rise to biological evolution. Evolutionary changes can result in the formation of novel varieties and entire new species. These changes are responsible for the diverse forms of life inhabiting the planet. The evidence for evolution suggests that all living organisms descended from common ancestors.

01:21Introduction to Test of Independence
3.0K
In statistics, the term independence means that one can directly obtain the probability of any event involving both variables by multiplying their individual probabilities. Tests of independence are chi-square tests involving the use of a contingency table of observed (data) values.
The test statistic for a test of independence is similar to that of a goodness-of-fit test:

01:16Hypothesis Test for Test of Independence
8.2K
The test of independence is a chi-square-based test used to determine whether two variables or factors are independent or dependent. This hypothesis test is used to examine the independence of the variables. One can construct two qualitative survey questions or experiments based on the variables in a contingency table. The goal is to see if the two variables are unrelated (independent) or related (dependent). The null and alternative hypotheses for this test are:
H0: The two variables (factors)...

02:03Law of Independent Assortment
62.8K
While Mendel’s Law of Segregation states that the two alleles for one gene are separated into different gametes, a different question of how different genes are inherited remains. For example, is the gene for tall plants inherited with the gene for green peas? Mendel asked this question by experimenting with a dihybrid cross; a cross in which both parents are homozygous for two distinct traits resulting in an F1 generation that are heterozygous for both traits.

01:18Independent and Dependent Sources
2.6K
In electrical circuits, sources play a crucial role in providing power for the operation of the circuit. These sources can be broadly categorized into two types: independent and dependent.
Independent voltage or current sources supply a fixed amount of voltage or current, respectively, which is unaffected by other elements within the circuit. These are represented using specific symbols. Independent voltage sources are symbolized with polarities (+ and -), indicating the direction of the...

00:59Model-Independent Approaches for Pharmacokinetic Data: Noncompartmental Analysis
334
Noncompartmental analyses offer an alternative method for describing drug pharmacokinetics without relying on a specific compartmental model. In this approach, the drug's pharmacokinetics are assumed to be linear, with the terminal phase log-linear. This assumption allows for simplified analysis and interpretation of the drug's behavior in the body.
One important characteristic of noncompartmental analyses is that drug exposure increases proportionally with increasing doses. This...
