Enantioselective Total Synthesis of (-)-Arcutinine.

The first total synthesis of an arcutine-type C20-diterpenoid alkaloid arcutinine has been achieved in both racemic and asymmetric forms. Construction of the C4 quaternary center and the pyrrolidine E ring in an early stage proved to be important for achieving the successful synthesis of the target alkaloid. Strategically, an asymmetric conjugate addition/aldol cascade and a decarboxylative allylation reaction allowed the establishment of the vicinal all-carbon quaternary stereocenters at C4 and C5. Further...


Total Synthesis of the Sensitive Triyne Natural Product (4,5)-4,8-Dihydroxy-3,4-dihydrovernoniyne and All of Its Stereoisomers.

An efficient total synthesis of the revised structure of the sensitive triyne natural product, (4,5)-4,8-dihydroxy-3,4-dihydrovernoniyne, and all of its stereoisomers, that is, the previously proposed (4,5), (4,5), and (4,5), has been accomplished from chiral pool compounds l-mannonic-γ-lactone and d-glucono-δ-lactone. The key features involve a one-pot conversion of the chiral pool compounds into the γ-vinyl-β-hydroxy-γ-lactones, the heteroatom-directed Wacker oxidation, the Seyferth-Gilbert reaction,...

Cultural bistability and connectedness in a subdivided population.

We propose a stochastic model of cultural evolution in a hunter-gatherer population that is subdivided into demes (subpopulations) of variable size and distributed over a finite or infinite number of sites. We assume a skill acquirable by either social or individual learning, such as the knowhow for positive niche construction, which raises the carrying capacity of a site. We further assume a positive feedback between the number of individuals in a deme with the skill and the size of that deme, which entail...


Antagonizing P2Y12 Receptor Inhibitors: Current and Future Options.

There are clinical scenarios where the balance between the risk of ischemic and bleeding events leads to the clinical decision to reverse the antiplatelet effect of P2Y receptor inhibitors. These scenarios comprise emergency situations such as active severe bleeding, urgent procedures with presumed high bleeding risk, or major trauma with (anticipated) bleeding. Supplementation of platelets has been investigated in ex vivo as well as in in vivo studies. These studies indicate that the inhibition of adenosin...

How will cannabis legalization affect health, safety, and social equity outcomes? It largely depends on the 14 Ps.

Jurisdictions considering or implementing alternatives to cannabis supply prohibition will confront several decisions that will influence health, safety, and social equity outcomes. This essay highlights 14 of these design considerations, which all conveniently begin with the letter : 1) Production, 2) Profit motive, 3) Power to regulate, 4) Promotion, 5) Prevention and treatment, 6) Policing and enforcement, 7) Penalties, 8) Prior criminal records, 9) Product types, 10) Potency, 11) Purity, 12) Price, 13) ...

Hidden figures behind two-vehicle crashes: An assessment of the risk and external costs of drunk driving in Spain.

In this paper, we estimate the relative risk that drunk drivers pose on sober drivers, passengers and pedestrians, and quantify the external cost of drunk driving in Spain between 2004-2015. Eventually we arrive at the following conclusions. Firstly, we find the relative risk of drunk drivers causing a crash during the night to be between 2.7-3.9 times higher than that of sober drivers. Secondly, our results point to a decline in drunk driving offences alongside an increase in its punition, mainly after the...

Outcome of hand surgery in children with spasticity, a 9-year follow-up study.

To evaluate whether short-term positive effects on bimanual function after surgery of the paretic arm in cerebral palsy are maintained long term. Assisting Hand Assessment (AHA) and active range of motion was tested before surgery and at 7 month and 9-year follow-up (n=18). AHA improved significantly from 50 to 52 U at 7 months, but was not different from before surgery at the 9-year follow-up, 49 U. Surgery of wrist and elbow flexors significantly improved active extension. Improvement in wrist and elb...

Antigen receptor control of methionine metabolism in T cells.

Immune activated T lymphocytes modulate the activity of key metabolic pathways to support the transcriptional reprograming and reshaping of cell proteomes that permits effector T cell differentiation. The present study uses high resolution mass spectrometry and metabolic labelling to explore how murine T cells control the methionine cycle to produce methyl donors for protein and nucleotide methylations. We show that antigen receptor engagement controls flux through the methionine cycle and RNA and histone m...

The Postoperative Speech Intelligibility Evaluation of Modified Z-Plasty Palatoplasty.

The aim of the present study is to test the feasibility of modified Z-plasty palatoplasty for cleft palate repair in surgeries and provide a new surgical method. Forty cleft palate patients were selected as participants and divided into 2 groups in random. Twenty patients in the experiment group were treated by modified Z-plasty palatoplasty while the other 20 patients in the control group by double opposing Z-plasty and Sommerlad palatoplasty. By evaluating and observing postoperative velopharyngeal moveme...

Translation-dependent unwinding of stem-loops by UPF1 licenses Regnase-1 to degrade inflammatory mRNAs.

Regnase-1-mediated mRNA decay (RMD), in which inflammatory mRNAs harboring specific stem-loop structures are degraded, is a critical part of proper immune homeostasis. Prior to initial translation, Regnase-1 associates with target stem-loops but does not carry out endoribonucleolytic cleavage. Single molecule imaging revealed that UPF1 is required to first unwind the stem-loops, thus licensing Regnase-1 to proceed with RNA degradation. Following translation, Regnase-1 physically associates with UPF1 using t...

Immunoglobulin G and Subclasses as Potential Biomarkers in Metastatic Melanoma Patients Starting Checkpoint Inhibitor Treatment.

Checkpoint inhibitors have improved survival of metastatic melanoma. However, reliable biomarkers to predict response are still needed. Immunoglobulin G (IgG) antibody subclasses reflect immunocompetence in individuals and are known to be involved in essential functions in our immune system. This prospective study evaluated the association between serum IgG with its subclasses IgG1, IgG2, IgG3, and IgG4 and antitumor response according to RECIST 1.1. Serum samples from 49 patients were prospectively collect...

A Homeostatic Arid1a-Dependent Permissive Chromatin State Licenses Hepatocyte Responsiveness to Liver-Injury-Associated YAP Signaling.

Following injury, differentiated epithelial cells can serve as a stem cell-independent source for tissue regeneration by undergoing reprogramming into other cell types. The intrinsic molecular basis underlying plasticity of differentiated cells remains largely unaddressed. Here we show that Arid1a, a key component of the SWI/SNF chromatin remodeling complex, controls liver regeneration and gene expression associated with emergence of injury-induced liver-progenitor-like cells (LPLCs). Hepatocyte-specific Ar...

Patent pledges, open IP, or patent pools? Developing taxonomies in the thicket of terminologies.

Recently, a range of organisations, including car and consumer electronics manufacturers, have applied so-called patent pledges. A patent pledge is a publicly announced intervention by patent-owning entities ('pledgers') to out-license active patents to the restricted or unrestricted public free from or bound to certain conditions for a reasonable or no monetary compensation. Despite growing research to better understand this phenomenon, the underlying terminology remains contradictory. We apply an inductiv...

Positional dependence of activity determination in single photon emission computed tomography.

Accurate image quantification requires accurate calibration of the detector and is vital if dosimetry is to be performed in molecular radiotherapy. A dependence on the position of calibration has been observed in single photon emission computed tomography images when attenuation correction (AC) and scatter correction are applied. This work investigates the origin of this dependence in single photon emission computed tomography scans of phantom inserts filled with Lu solution. A 113 ml sphere and inserts r...

Horizontal Transmission of Hepatitis B Virus From Mother to Child Due to Immune Escape Despite Immunoprophylaxis.

Hepatitis B virus (HBV) vaccination starting at birth is approximately 95% effective in preventing mother-to-child transmission to infants born to HBV-infected mothers. A higher risk of transmission is associated with birth to a highly viremic mother, often due to transplacental exposure, while later horizontal transmission is much less common, particularly following complete vaccination. This study reports a case of infection in an older child despite appropriate immunoprophylaxis starting at birth and an ...

First Implantation of Retinal Prosthesis in a Patient with High Myopia After Surgery and Rehabilitation Program in Taiwan.

The implantation of the Argus II retinal prosthesis system in a 54-year-old woman with retinitis pigmentosa who presented with an eye of long axial length at 26.82 mm was successful. Post-operative examination revealed a gap of 700 um between the electrode array and the retina, which caused decreased visual perception. A modified strategy with quad and quinary electrode stimulation was introduced to generate higher perceptual thresholds. The patient experienced visual function changes during the first half ...

Optimizing observer performance of clinic blood pressure measurement: a position statement from the Lancet Commission on Hypertension Group.

: High blood pressure (BP) is a highly prevalent modifiable cause of cardiovascular disease, stroke, and death. Accurate BP measurement is critical, given that a 5-mmHg measurement error may lead to incorrect hypertension status classification in 84 million individuals worldwide. This position statement summarizes procedures for optimizing observer performance in clinic BP measurement, with special attention given to low-to-middle-income settings, where resource limitations, heavy workloads, time constraint...

Implicit Measures of Receptive Vocabulary Knowledge in Individuals With Level 3 Autism.

Implicit measures of cognition are essential for assessing knowledge in people with Level 3 autism because such individuals are often unable to make reliable overt behavioral responses. In this study, we investigated whether three implicit measures-eye movement (EM) monitoring, pupillary dilation (PD), and event-related potentials (ERPs)-can be used to reliably estimate vocabulary knowledge in individuals with Level 3 autism. Five adults with Level 3 autism were tested in a repeated-measures design with two...

A Root Cause Analysis Into the High Error Rate in Clinical Immunohistochemistry.

The field of Clinical Immunohistochemistry (IHC) is beset with a high error rate, an order of magnitude higher than in other types of clinical laboratory testing. Despite the many improvements in the field, these errors have persisted over the last 2 decades. The improvements over the years include an extensive literature describing the potential causes of errors and how to avoid them. More stringent regulatory guidelines have also been implemented. These measures reflect the standard view is that fixing th...

Ra-223 Treatment for Bone Metastases in Castrate-Resistant Prostate Cancer: Practical Management Issues for Patient Selection.

Bone metastases are common in men with metastatic castrate-resistant prostate cancer (mCRPC), occurring in 30% of patients within 2 years of castrate resistance and in >90% of patients over the disease course. There are 6 US Food and Drug Administration-approved therapies for mCRPC with demonstrated survival benefit. Of these, only radium-223 (Ra-223) specifically targets bone metastases, delays development of skeletal-related events, and improves survival. This review discusses key data from the ALSYMPCA t...

Minimally Invasive Cervical Pedicle Screw Fixation (MICEPS) via a Posterolateral Approach.

Cervical pedicle screw (PS) fixation provides great mechanical strength; however, it needs wide soft tissue detachment and has vertebral artery damage risk. Minimally invasive cervical pedicle screw (MICEPS) fixation, a new method for cervical PS fixation through a posterolateral approach, was developed to reduce soft tissue damage and avoid lateral misplacement of screws. Sixty-seven patients with cervical injury underwent MICEPS fixation. They were positioned prone on a radiolucent carbon table with a car...
