Self-induced extreme intoxication akin to automatism: A psycholegal tug of war.

Self-induced extreme intoxication akin to automatism (SIEA) is a complicated and controversial legal concept resistant to jurisdictional consensus. In the United States, SIEA has, at times, been considered under the concept of "settled insanity.".

Degradable multifunctional gold-liposomes as an all-in-one theranostic platform for image-guided radiotherapy.

To improve tumor destruction and minimize adverse effects to healthy tissues, image-guided radiation therapy (IGRT) has been developed to allow for the accurate delivery of radiation energy to tumor sites facilitated by real-time imaging. Nevertheless, the current IGRT platform still suffers from the limitation of poor tissue contrast, resulting in the incidental irradiation of healthy tissue. Gold nanoparticles (GNPs) have been identified as promising candidates to simultaneously improve both radiotherapy and imaging, thereby improving both the accuracy and safety of IGRT.

Massive Saddle Pulmonary Embolism in a Preterm Neonate With Successful Emergent Open Embolectomy.

Pulmonary embolism in the neonate is a rare, life-threatening emergency. Risk factors for neonatal pulmonary embolism (PE) include sepsis, asphyxia, prematurity, and vascular catheterisation. We report the case of a preterm neonate with a massive saddle pulmonary thrombosis of unidentified etiology.

Oncological and functional outcomes following treatment of T1a glottic squamous cell carcinoma with transoral laser microsurgery.

Background: Laryngeal cancers of glottic origin comprise a large proportion of head and neck malignancies. Transoral laser microsurgery (TLM) and radiation therapy are mainstays in the treatment of early stage glottic cancer, but debate persists as to which modality is functionally superior. Furthermore, there is a paucity of North American data related to functional and oncological outcomes in T1a glottic cancer.

Treatment Choices in Managing Bethesda III and IV Thyroid Nodules: A Canadian Multi-institutional Study.

Objective: Patient-centered decision making is increasingly identified as a desirable component of medical care. To manage indeterminate thyroid nodules, patients are offered the options of surveillance, diagnostic hemithyroidectomy, or molecular testing. Our objective was to identify factors associated with decision making in this population.

Oral Losartan After Limited Mandibulectomy for Treatment of Desmoid-Type Fibromatosis.

Desmoid-type fibromatosis (DF) is a rare soft tissue lesion with an annual incidence of 2 to 4 per million population and peak incidence occurring at approximately 4.5 years of age. While benign, the tumor has a locally aggressive infiltrative growth pattern and a high rate of recurrence.

Medical Intervention Alone vs Surgical Drainage for Treatment of Peritonsillar Abscess: A Systematic Review and Meta-analysis.

Objective: Peritonsillar abscesses (PTAs) are common emergency consultations for otolaryngologists. Medical management alone may offer satisfactory treatment without the risk associated with surgical drainage. Therefore, we performed a systematic review of medical treatment alone compared to surgical drainage for the treatment of PTA.

Regenerative nanobots based on magnetic layered double hydroxide for azo dye removal and degradation.

A highly regenerative multifunctional nanobot system, using FeO@SiO@MgFe-LDH nanoparticles, is developed for efficient removal of waterborne azo dyes and pharmaceuticals. Efficient capture of pollutants, powerful Fenton degradation, and superior materials regeneration lead to a simple and cost-effective wastewater remediation solution.

Chloride-accelerated Cu-Fenton chemistry for biofilm removal.

Biofilms present challenges to numerous industries. Herein, a simple approach was developed based on chloride-accelerated Fenton chemistry, where copper oxide nanoparticles facilitate efficient generation of reactive chlorine species for biofilm removal.

Highly Hybridizable Spherical Nucleic Acids by Tandem Glutathione Treatment and Polythymine Spacing.

Gold nanoparticle (AuNP)-templated spherical nucleic acids (SNAs) have been demonstrated as an important functional material in bionanotechnology. Fabrication of SNAs having high hybridization capacity to their complementary sequences is critical to ensure their applicability in areas such as antisense gene therapy and cellular sensing. The traditional salt-aging procedure is effective but tedious, requiring 1-3 days to complete.

Chemisorption Mechanism of DNA on Mg/Fe Layered Double Hydroxide Nanoparticles: Insights into Engineering Effective SiRNA Delivery Systems.

Layered double hydroxide nanoparticles (LDH NPs) have attracted interest as an effective gene delivery vehicle in biomedicine. Recent advances in clinic trials have demonstrated the efficacy of Mg/Fe LDHs for hyperphosphatemia treatment, but their feasibility for gene delivery has not been systematically evaluated. As a starting point, we aimed to study the interaction between oligo-DNA and Mg/Fe LDH NPs.

Driving Adsorbed Gold Nanoparticle Assembly by Merging Lipid Gel/Fluid Interfaces.

Surface forces between inorganic nanoparticles and lipid bilayer is of great relevance to biophysics, medicine, and nanobiotechnology. Adsorbed nanoparticles may influence the fluidity of the underlying lipids, which may in turn influence nanoparticle assembly. Herein three types of lipids (DOPC, Tc = -20 °C; DMPC, Tc = 23 °C; and DPPC, Tc = 41 °C) are used, all with the same phosphocholine (PC) headgroup.

Adsorption of doxorubicin on citrate-capped gold nanoparticles: insights into engineering potent chemotherapeutic delivery systems.

Gold nanomaterials have received great interest for their use in cancer theranostic applications over the past two decades. Many gold nanoparticle-based drug delivery system designs rely on adsorbed ligands such as DNA or cleavable linkers to load therapeutic cargo. The heightened research interest was recently demonstrated in the simple design of nanoparticle-drug conjugates wherein drug molecules are directly adsorbed onto the as-synthesized nanoparticle surface.
