Shuhong Luo, Melanie Kalman
The purpose of this paper is to describe and discuss how we designed and developed a 12-step technology training protocol. The protocol is meant to improve meaningful learning in technology education so that nursing students are able to meet the informatics requirements of Quality and Safety Education in Nursing competencies. When designing and developing the training protocol, we used a simplified experiential learning model that addressed the core features of meaningful learning: to connect new knowledge with students' prior knowledge and real-world workflow...

Although prosody clearly affects the interpretation of utterances, the mapping between prosodic representations and acoustic features is highly variable. Listeners may in part cope with this variability by adapting to distributions of acoustic features in the input. We examined whether listeners adapt to distributional changes using the construction It looks like an X. When pronounced with an H* pitch accent on the final noun and a low boundary tone, the construction supports an affirmative interpretation (e...

BACKGROUND: Injection drug use is associated with HIV and hepatitis C transmission, overdose, and other preventable harms. These harms are heightened for structurally vulnerable injection drug-using populations, as their social conditions pose barriers to safer injecting. Previous research on injection cessation has largely focused on adult drug-using populations. Little qualitative work has examined the social, structural, and environmental factors that shape periods of injection cessation among youth and young adults...

PROBLEM: Substance use disorders (SUDs) affect millions of Americans. Nevertheless, there is insufficient health care resource allocation for these patients. One reason may be the lack of education and training about SUDs in health professions programs. APPROACH: The authors developed a required, interprofessional SUDs course for health professions students completing a one-month psychiatry clerkship within the Duke University Health System starting in November 2015...

A short enantioselective synthesis of 6-substituted cis-2,8-dioxabicyclo[3.3.0]octan-3-ones is described. The pivotal step is coupling of a tertiary radical generated directly from a tertiary alcohol with a 3-chloro-5-alkoxybutenolide. This strategy is applied toward scalable 14-15 step syntheses of three rearranged spongian diterpenoids: cheloviolenes A and B and dendrillolide C.

BACKGROUND: Recovery features strongly in Australian mental health policy; however, evidence is limited for the efficacy of recovery-oriented practice at the service level. This paper describes the Principles Unite Local Services Assisting Recovery (PULSAR) Specialist Care trial protocol for a recovery-oriented practice training intervention delivered to specialist mental health services staff. The primary aim is to evaluate whether adult consumers accessing services where staff have received the intervention report superior recovery outcomes compared to adult consumers accessing services where staff have not yet received the intervention...

The first total synthesis of the potent antimalarial 7,3'-linked naphthylisoquinoline alkaloid dioncophylline E (1) has been completed. The synthesis proceeds in 12 steps (longest linear sequence) and in 15 % overall yield. Key transformations include an ortho-arylation of a naphthol with an aryllead triacetate to construct the sterically hindered biaryl bond, and a three-step sequence to stereoselectively generate the trans-1,3-dimethyl-1,2,3,4-tetrahydroisoquinoline moiety.

The kodaistatins are natural products from Aspergillus terreus. Being strongly anti-diabetic they hold some promise of a novel diabetes cure. However, considerations of that kind face two drawbacks. (1) The kodaistatins contain a heavily substituted pulvinone/cyclopentenone combination. (2) The kodaistatins are 1,2-diols, whose 3D structure have not been assigned yet. However, we can exclude two of the four possible stereostructures. We conclude that kodaistatin A is a trans-, not a cis-diol, from NMR comparisons with a pair of cis,trans-isomeric kodaistatin models, which we synthesized in 11 and 12 steps, respectively...

β-Carotene is a terpenoid molecule with high hydrophobicity that is often used as an additive in foods and feed. Previous work has demonstrated the heterologous biosynthesis of β-carotene from an intrinsic high flux of acetyl-CoA in 12 steps through 11 genes in Yarrowia lipolytica. Here, an efficient biosynthetic pathway capable of producing 100-fold more β-carotene than the baseline construct was generated using strong promoters and multiple gene copies for each of the 12 steps. Using fed-batch fermentation with an optimized medium, the engineered pathway could produce 4g/L β-carotene, which was stored in lipid droplets within engineered Y...

This commentary is to inform clinicians challenged with an increase in people seeking treatment for Substance Use Disorder (SUD), that the ninety percent revolving door, is, in part, due to post-withdrawal, untreated neurotoxicity. This impairment attenuates neurotransmitter signaling and compromises resting state functional connectivity, leading to unwanted sequelae including depression, sleep disturbances, sensation seeking, lack of satisfaction and impulsivity. Neuroimaging studies indicate that neurobiological recovery can take years...

The enantioselective synthesis of (+)-lysergol was completed in 12 steps and an overall yield of 13% starting from a known literature precursor. The key step relies on a domino reaction containing a formal anti-carbopalladation, which is terminated by a β-silyl-directed Heck reaction. During this transformation, the two six-membered rings of the ergot scaffold are formed in a completely stereospecific manner.

An efficient enantioselective 12-step synthesis of the ABCDE pentacyclic core of the Strychnos alkaloids is described. A key feature of this approach is an organocatalyzed enantioselective desymmetrization to generate the morphan core in high ee and dr. After palladium-catalyzed installation of the indole moiety, a subsequent 5-exo-trig dearomatizing atom transfer radical cyclization was developed to construct the C-ring. Following a series of functional group interconversions, the pentacyclic amine core was obtained with all the relevant architecture including five stereocenters pertaining to the Strychnos alkaloids...

This study examined patterns of medicalization in substance use disorder (SUD) that are aligned with the goals of the Affordable Care Act (ACA). Using a nationally representative sample of SUD treatment programs, we examined changes in several treatment domains. While observed changes were modest, they were in directions that support the thrust of the ACA. Specifically, we found an increase in the percentage of treatment referrals from other health care providers. We found an increase in the number of physicians for programs that did have a physician on staff, and an increase in counselors certified in treating alcohol and drug addiction...

We report a 12-step catalytic enantioselective formal synthesis of malhamensilipin A (3) and diastereoisomeric analogues from (E)-2-undecenal. The convergent synthesis relied upon iterative epoxidation and phosphorus(v)-mediated deoxydichlorination reactions as well a titanium-mediated epoxide-opening to construct the C11-C16 stereohexad. The latter transformation occurred with very high levels of stereoretention regardless of the C13 configuration of the parent epoxide, implicating anchimeric assistance of either the γ- or δ-chlorine atoms, and the formation of chloretanium or chlorolanium ions, respectively...

OBJECTIVE: Behavioral couples therapy (BCT) is more efficacious than individually-based therapy (IBT) for substance and relationship outcomes among substance use disorder patients. This study compared BCT with IBT for drug-abusing women. METHOD: Sixty-one women, mostly White, late 30s, with primary substance use disorder other than alcohol (74% opioid), and male partners were randomized to 26 sessions over 13 weeks of BCT plus 12-step-oriented IBT (i.e., BCT + IBT) or IBT...

Increasingly over the past decade, faculty in medical and graduate schools have received requests from digital millennial learners for concise faculty-made educational videos. At our institution, over the past couple of years alone, several hundred educational videos have been created by faculty who teach in a flipped-classroom setting of the pre-clinical medical school curriculum. Despite the appeal and potential learning benefits of digital chalk-talk videos first popularized by Khan Academy, we have observed that the conceptual and technological barriers for creating chalk-talk videos can be high for faculty...

The first enantiospecific synthesis of hispidanin A (4), a dimeric diterpenoid from the rhizomes of Isodon hispida, was achieved with a longest linear sequence of 12 steps in 6.5 % overall yield. A key component is the use of the abundant and naturally occurring diterpenoids (+)-sclareolide and (+)-sclareol as starting materials, which enables the gram-scale preparation of the key intermediates totarane (1) and s-trans-12E,14-labdadien-20,8β-olide (2). Subsequently a thermal or an erbium-catalyzed intermolecular Diels-Alder reaction of totarane (1) with labdadienolide (2) provide convergent and rapid access to the natural product hispidanin A (4)...
