First Evidence of Hepatozoon canis in Dogs With Clinical Signs in the North of Lima, Peru
This study was aimed at detecting the presence of Hepatozoon canis in dogs with clinical signs in the northern area of Lima, Peru. Peripheral blood samples (n = 152) were collected from dogs with hematological alterations and clinical signs suggestive of hemoparasitosis. PCR was used to amplify the…

Cannabis Use in Adolescent and Young Adult Athletes: A Clinical Review
CONTEXT: Cannabis use among the general population has increased over time, in part due to decriminalization of use and greater social acceptance of cannabis use. These changes have contributed to increased availability of cannabis products, thus raising the likelihood that a subset of adolescent…

Controlling anthracnose by means of extracts, and their major constituents, from Brosimum rubescens Taub
Anthracnose, caused by the fungus Colletotrichum gloeosporioides (Penz.) Penz. & Sacc., is the most limiting fungal disease of mango and papaya crops in Colombia. The in vivo and in vitro activity against C. gloeosporioides of the extracts from sawdust of Brosimum rubescens Taub. (Moraceae) was…

Leishmania braziliensis SCD6 and RBP42 proteins, two factors with RNA binding capacity
BACKGROUND: The study of RNA binding proteins (RBPs) is of great relevance for understanding processes like post-transcriptional control of gene expression. The post-transcriptional mechanisms are particularly important in Leishmania parasites and related trypanosomatids since transcriptional…

Mechanomorphological Guidance of Colloidal Gel regulates Cell Morphogenesis
Microstructural morphology of extracellular matrix guides the organization of cells in three dimensions (3D). However, current biomaterials-based matrices cannot provide distinct spatial cues through their microstructural morphology due to design constraints. To address this, colloidal gels were…

Pre-Operative Management of the Penicillin Allergic Patient: A Narrative Review
Penicillin is a frequently reported medication allergy. The beta-lactam ring shared between cephalosporins and penicillin often leads to the use of alternative antibiotics for surgical prophylaxis due to concern for cross-reactivity, despite a true IgE-mediated hypersensitivity being very rare…

Inhibition of juvenile hormone synthesis in mosquitoes by the methylation inhibitor 3-Deazaneplanocin A (DZNep)
Juvenile hormone (JH), synthesized by the corpora allata (CA), controls development and reproduction in mosquitoes through its action on thousands of JH-responsive genes. These JH-dependent processes can be studied using tools that increase or decrease JH titers in vitro and in vivo. Juvenile…

Common structural features facilitate the simultaneous identification and quantification of the five most common juvenile hormones by liquid chromatography-tandem mass spectrometry.
This study reports the development and application of a liquid chromatography method coupled to electrospray tandem mass spectrometry (LC-MS/MS) for the identification and quantification of the five most common juvenile hormone (JH) homologs and methyl farnesoate (MF). The protocol allows the…

Mapping Biomaterial Complexity by Machine Learning
Biomaterials often have subtle properties that ultimately drive their bespoke performance. Given this nuanced structure–function behavior, the standard scientific approach of one experiment at a time or design of experiment methods is largely inefficient for the discovery of complex biomaterials…

Three Dimensional Secondary Ion Mass Spectrometry Imaging (3D-SIMS) of Aedes aegypti ovarian follicles
The mobilization of nutrient reserves into the ovaries of Aedes aegypti mosquitoes after sugar-feeding plays a vital role in the female’s reproductive maturation. In the present work, three-dimensional secondary ion mass spectrometry imaging (3D-SIMS) was used to generate ultrahigh spatial…

Architecting a partial thickness cartilage substitute with mimetic, self-assembling hydrogels
Restoration of partial thickness chondral defects (PTCDs) may be achieved with a synthetic substitute that mimics the discrete mechanical properties of the superficial and transitional chondral layers. Moreover, innate adhesivity of the two components would enable the facile construction and…

Coupling stable isotope labelling and LC-TIMS-TOF MS/MS for de novo mosquito ovarian lipid studies
There is a need to better understand the lipid metabolisms during the mosquito ovarian development. Lipids are the major source of energy supporting ovarian follicles development in mosquitoes. In this paper, we describe the complementary use of stable isotope labelling (SIL) and high-resolution…

Leishmania braziliensis replication protein A subunit 1: molecular modelling, protein expression and analysis of its affinity for both DNA and RNA
BACKGROUND: Replication factor A (RPA) is a single-strand DNA binding protein involved in DNA replication, recombination and repair processes. It is composed by the subunits RPA-1, RPA-2 and RPA-3; the major DNA-binding activity resides in the subunit 1 of the heterotrimeric RPA complex. In yeast…
