Published: July 2019

A gold (I)-catalyzed reaction of enyne-ethers to rapidly construct oxa-bridged compounds via a tandem 1,2-acyloxy migration/intramolecular oxonium formation/1,2-rearrangement process was reported. The reaction was shown to be robust with a wide range of substitution patterns tolerated to provide the corresponding oxygen-containing bridged products in good to excellent yields.

Individuals with Mild Cognitive Impairment (MCI) and dementia are at greater risk for mental health conditions including depression and anxiety than those without cognitive impairments. Non-pharmacological interventions are considered first-line to address these problems, but access to psychotherapy services for these groups remains limited. Adapted evidence-based therapy approaches, including Cognitive Behavioral Therapy (CBT) and Acceptance and Commitment Therapy (ACT) are effective for treating comorbid mental health conditions in populations with cognitive impairments.

While the conformational ensembles of disordered peptides and peptidomimetics are complex and challenging to characterize, they are a critical component in the paradigm connecting macromolecule sequence, structure, and function. In molecules that do not adopt a single predominant conformation, the conformational ensemble contains rich structural information that, if accessible, can provide a fundamental understanding related to desirable functions such as cell penetration of a therapeutic or the generation of tunable enzyme-mimetic architecture. To address the fundamental challenge of describing broad conformational ensembles, we developed a model system of peptidomimetics comprised of polar glycine and hydrophobic -butylglycine to characterize using a suite of analytical techniques.

Despite the growing interest in mirror-image l-oligonucleotides, both as a robust nucleic acid analogue and as an artificial genetic polymer, their broader adoption in biochemical research and medicine remains hindered by challenges associated with the synthesis of long sequences, especially for l-RNA. Herein, we present a novel strategy for assembling long l-RNAs the joining of two or more shorter fragments using cross-chiral ligase ribozymes together with new substrate activation chemistry. We show that 5'-monophosphorylated l-RNA, which is readily prepared by solid-phase synthesis, can be activated by chemical attachment of a 5'-adenosine monophosphate (AMP) or diphosphate (ADP), yielding 5'-adenosyl(di- or tri-)phosphate l-RNA.

Introduction  Diabetes is a rapidly growing global health concern, with the World Health Organization (WHO) estimating that 300 million adults will have diabetes by 2025. This chronic condition is associated with complications, including nephropathy, retinopathy, neuropathy, cardiovascular disease, and diabetic foot ulcers (DFUs), which can lead to amputation. Diabetic septic foot (DSF), a severe form of diabetic foot disease, is defined by the WHO as the presence of infection, ulceration, or tissue destruction in the lower limb, often accompanied by neurological abnormalities, peripheral vascular disease, and metabolic complications of diabetes.

The primary aim of this rapid review was to synthesize the literature on the healthcare experiences of women with substance use disorders (SUDs) during the prenatal and postnatal periods. The secondary aim was to discuss the implications of the findings, in the context of primary care nurse practitioner (NP) practice. A rapid review was conducted, synthesizing research evidence using abbreviated, systematic review methods to generate evidence in a shorter amount of time.
