Aptamer Engineering: Strategies for Discovering Functional Nucleic Acids for Next‐Generation Diagnostics and Biosensing

open access: yesAdvanced Science, EarlyView.
The advent of aptamers has highlighted their potential as alternatives to antibodies, overcoming limitations of structural instability and production cost. However, conventional approaches such as SELEX remain slow and labor‐intensive. This review examines recent advances in aptamer engineering, emphasizing in vitro and AI‐driven in silico strategies ...

Detection and identification of Leishmania species within naturally infected sand flies in the Andean areas of Ecuador by a polymerase chain reaction [PDF]

open access: yes, 2005
The surveillance of prevalent Leishmania and sand fly species in endemic areas is important for prediction of the risk and expansion of leishmaniasis. In this study, we developed a polymerase chain reaction (PCR)-based method for detection of Leishmania ...

Heterogeneity of cysteine proteinases in Leishmania braziliensis and Leishmania major.

open access: yesBrazilian journal of medical and biological research = Revista brasileira de pesquisas medicas e biologicas, 1994
Sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) with acrylamide copolymerized with gelatin (substrate-SDS-PAGE) was used to compare promastigote proteinases from two Leishmania species (L. braziliensis and L. major-like). Substrate-SDS-PAGE resolved at least 6 distinct proteinase activities with relative molecular masses between 20

LeishCyc: a biochemical pathways database for Leishmania major [PDF]

open access: yesBMC Systems Biology, 2009
Abstract Background Leishmania spp. are sandfly transmitted protozoan parasites that cause a spectrum of diseases in more than 12 million people worldwide. Much research is now focusing on how these parasites adapt to the distinct nutrient environments they encounter in the digestive tract of the ...

Epstein–Barr Virus, Lower Vitamin D, Low Sun Exposure, and HLA‐DRB1*1501 Risk Variant Share Common Epigenetic Pathways Leading to Multiple Sclerosis Onset

open access: yesAnnals of Neurology, EarlyView.
Objectives Multiple sclerosis (MS) onset risk factors include Epstein–Barr virus (EBV) indices (including host response), lower serum 25‐vitamin D (25(OH)D) levels, low sun exposure, and HLA‐DRB1*1501. The underlying molecular mechanisms are unclear. Here, we examined mediation through differential DNA methylation (DNAm) to better understand possible ...

Effect of interleukin-22 on immunogenicity of DNA vaccine encoding TSA gene of leishmania major in BALB/c mice [PDF]

open access: yes, 2014
Background and purpose: Previous Research shows the use of plasmids containing genes TSA to be useful as vaccines for Leishmania major. Recently, the role of interleukin-22 (IL-22) in tissue repair has been demonstrated.

Safety, tolerability and pharmacokinetics of DNDI‐6148, a novel agent for leishmaniasis: A randomized, controlled, single ascending dose study in healthy participants

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Aim The benzoxaborole derivative DNDI‐6148 is an antiparasitic agent with activity against multiple Leishmania protozoan species, including L. infantum and L. donovani, which cause visceral leishmaniasis. We investigated the safety, tolerability and pharmacokinetics of single oral doses of DNDI‐6148 in a randomized, parallel‐group, placebo‐controlled ...

Leishmaniasis: new approaches to disease control. [PDF]

open access: yes, 2003
The leishmaniases afflict the world's poorest populations. Among the two million new cases each year in the 88 countries where the disease is endemic (fig 1), it is estimated that 80% earn less than $2 a day.

Could the Biological Potency of Porcelia macrocarpa R.E. Fries (Annonaceae) be Linked to Its Diverse Metabolite Profile?

open access: yesChemistry &Biodiversity, EarlyView.
ABSTRACT Porcelia macrocarpa is a Brazilian plant species belonging to the Annonaceae family. To date, more than 190 compounds have been identified and/or isolated from this species, with terpenoids comprising the majority (62%). Alkaloids represent the second most abundant class (11%), followed by steroids (4%), acetogenins (4%), fatty acids (4 ...
