Genetic polymorphisms and drug susceptibility in four isolates of Leishmania tropica obtained from Canadian soldiers returning from Afghanistan. [PDF]

PLoS Neglected Tropical Diseases, 2012
Cutaneous leishmaniasis (CL) is a vector-borne parasitic disease characterized by the presence of one or more lesions on the skin that usually heal spontaneously after a few months.

Lynx: Using OS and hardware support for fast fine-grained inter-core communication [PDF]

, 2016
Designing high-performance software queues for fast intercore communication is challenging, but critical for maximising software parallelism. State-of-the-art single-producer / single-consumer queues for streaming applications contain multiple sections ...

Moth oviposition shapes the species-specific transcriptional and phytohormonal response of Nicotiana attenuata to larval feeding [PDF]

, 2018
Oviposition by lepidopteran herbivores on Nicotiana attenuata primes plant defence responses that are induced by the feeding larvae. While oviposition by both the generalist Spodoptera exigua and the specialist Manduca sexta primes the production of ...

Inactivation of the Leishmania tarentolae Pterin Transporter (BT1) and Reductase (PTR1) Genes Leads to Viable Parasites with Changes in Folate Metabolism and Hypersensitivity to the Antifolate Methotrexate [PDF]

Journal of Biological Chemistry, 2004
The protozoan parasite Leishmania is a folate and pterin auxotroph. The main biopterin transporter (BT1) and pterin reductase (PTR1) have already been characterized in Leishmania. In this study, we have succeeded in generating a BT1 and PTR1 null mutant in the same Leishmania tarentolae strain.

Bridging Portability and Performance in Sparse Tensor Computations Using SYCL

Concurrency and Computation: Practice and Experience, Volume 37, Issue 27-28, 25 December 2025.
ABSTRACT Sparse tensors have become prevalent data structures in multiple applications, such as medical imaging and machine learning, making operations that decompose them, that is, creating smaller structures that retain most of the original information, essential.

Identification of Novel Potential Inhibitors of Pteridine Reductase 1 in Trypanosoma brucei via Computational Structure-Based Approaches and in Vitro Inhibition Assays

Molecules, 2019
Pteridine reductase 1 (PTR1) is a trypanosomatid multifunctional enzyme that provides a mechanism for escape of dihydrofolate reductase (DHFR) inhibition. This is because PTR1 can reduce pterins and folates.

RIN4 immunity regulators mediate recognition of the core effector RipE1 of Ralstonia solanacearum by the receptor Ptr1 [PDF]

Plant Physiology
Abstract Ralstonia solanacearum causes lethal bacterial wilt diseases in numerous crops, resulting in considerable yield losses. Harnessing genetic resistance is desirable for safeguarding plants against phytopathogens. However, genetic resources resistant to bacterial wilt are limited in crops.

Highly efficient deep‐blue organic light‐emitting diodes with high color‐purity enabled by triptycene‐enhanced rigid Pt(II) complexes

FlexMat, Volume 2, Issue 4, Page 630-642, December 2025.
Novel enhanced‐rigid tetradentate Pt(II) emitters were developed via the first strategic merging of a pyramidal triptycene unit into the 2,3‐positions of the carbazole moiety. PtJY2‐based bottom‐emitting PhOLED represents one of the best‐balanced performances, including excellent EQEs, low roll‐off, and high color purity, among the reported non ...

Unresponsiveness to Glucantime treatment in Iranian cutaneous leishmaniasis due to drug-resistant Leishmania tropica parasites. [PDF]

PLoS Medicine, 2006
BACKGROUND: Recent circumstantial evidence suggests that an increasing number of Iranian patients with cutaneous leishmaniasis are unresponsive to meglumine antimoniate (Glucantime), the first line of treatment in Iran.

Recoil correction to the bound-electron g factor in H-like atoms to all orders in $\alpha Z$ [PDF]

, 2001
The nuclear recoil correction to the bound-electron g factor in H-like atoms is calculated to first order in $m/M$ and to all orders in $\alpha Z$. The calculation is performed in the range Z=1-100.
