β-Triketones from Leptospermum scoparium (mānuka) oil show potential as scabicides.

Background: Scabies is a debilitating and neglected infectious disease with limited effective treatment options and affecting millions of people worldwide, mainly in poor and overcrowded settings. Essential oils from Australasian Myrtaceae are known to have parasiticidal properties, often attributed to the presence of β-triketones, which are known inhibitors of the tyrosine catabolism pathway through inhibition of hydroxyphenylpyruvate dioxygenase (HPPD).

Purpose: In this study, essential oils from mānuka (Leptospermum scoparium) were evaluated in vitro for miticidal and ovicidal activities and their active β-triketone constituents (flavesone, leptospermone, and isoleptospermone) were identified.

Basic Science and Pathogenesis.

Background: The SORL1 gene (SORLA) is strongly associated with risk of developing Alzheimer's disease (AD). SORLA is a regulator of endosomal trafficking in neurons and interacts with retromer, a complex that is a "master conductor" of endosomal trafficking. Because of its size, SORLA is difficult to target therapeutically.

Development of 6-amido-4-aminoisoindolyn-1,3-diones as p70S6K1 inhibitors and potential breast cancer therapeutics.

Introduction: Many breast cancer therapeutics target the PI3K/AKT/mTOR oncogenic pathway. Development of resistance to the therapeutics targeting this pathway is a frequent occurrence. Therapeutics targeting p70S6K1, a downstream member of this pathway, have recently gained importance due to its critical role in all types of breast cancer and its status as a prognostic marker.

Vaccination with different group 2 influenza subtypes alters epitope targeting and breadth of hemagglutinin stem-specific human B cells.

The conserved influenza hemagglutinin stem, which is a target of cross-neutralizing antibodies, is now used in vaccine strategies focused on protecting against influenza pandemics. Antibody responses to group 1 stem have been extensively characterized, but little is known about group 2. Here, we characterized the stem-specific repertoire of individuals vaccinated with one of three group 2 influenza subtypes (H3, H7, or H10).

Racial discrimination and adverse childhood experiences predicting depressive symptoms and developmental assets: Testing cultural socialization and preparation for bias as moderators among Black adolescents and caregivers.

The current study examined whether adverse childhood experiences and racial discrimination predicted adolescents' internal developmental assets, external developmental assets, and depressive symptoms. We also tested whether these relations were buffered by aspects of caregivers' reports of ethnic-racial socialization efforts (i.e.
