Genome Mining –Based Identification of Identical Multirepeat Sequences in Plasmodium falciparum Genome for Highly Sensitive Real-Time Quantitative PCR Assay and Its Application in Malaria Diagnosis
Malaria continues to impact global health, and developing ultrasensitive methods capable of detecting submicroscopic parasitemia —a challenge that persists in low transmission areas, asymptomatic carriers, and patients showing recrudescence—is vital to achieving malaria eradication. Nucleic acid amplification techniques offer improved analytical sensitivity but are limited by the number of copies of the amplification targ ets. Herein, we perform a novel genome mining approach to identify a pair of identical multirepeat sequences (IMRSs) that constitute 170 and 123 copies in the Plasmodium falciparum genome and explore their potential as primers for PCR.

In this study, we carried out qualitative and quantitative analysis of the donkey whey proteome using a label-free proteomic approach, combined with parallel reaction monitoring (PRM) as a validation method. A total of 300 whey proteins were identified in donkey colostrum (DC) and donkey mature (DM) milk, of which 18 were differentially expressed (P
Conclusions: ivA was highly efficacious in this pediatric cohort. We observed episodes of mild to moderate posttreatment hemolysis in approximately one-third of patients. The legal status and usage of potentially lifesaving ivA should be evaluated in Europe.
In conclusion, the overall results present the molecular characterization of annexin B30, annexin B5a, annexin B7a and annexin B5b from S. mansoni in host-parasite interactions and strongly suggest that the molecules could be useful candidates for vaccine or diagnostic development.
The level of human group IIA secreted phospholipase A2 (hGIIA sPLA2) is increased in the plasma of malaria patients, but its role is unknown. In parasite culture with normal plasma, hGIIA is inactive against Plasmodium falciparum, contrasting with hGIIF, hGV, and hGX sPLA2s, which readily hydrolyze plasma lipoproteins, release nonesterified fatty acids (NEFAs), and inhibit parasite growth. Here, we revisited the anti-Plasmodium activity of hGIIA under conditions closer to those of malaria physiopathology where lipoproteins are oxidized. In parasite culture containing oxidized lipoproteins, hGIIA sPLA2 was inhibitory, with ...
AbstractAlgeria, like all emerging countries, has been going through a health transition over the past 30 years or so, characterized by a drop in mortality rates, an increase in life expectancy and a change in the causes of death in favor of chronic non-communicable diseases. In the past, the country mainly faced infectious diseases such as typhoid, cholera and malaria. The prevalence of the latter ha s been significantly reduced thanks to the many social health and vaccination programs undertaken by the health authorities. As a result of this epidemiological transition, we are witnessing a growing increase in the in...

Caused by the bacteria Mycobacterium tuberculosis, TB commonly causes persistent coughing, fatigue and weight loss. According to the World Health Organization (WHO) and its latest Global TB Report, a...

Scientists have rediscovered a compound developed by German researchers during World War II. It appears to be more effective and perhaps safer than DDT.
