Introduction: To assess secondary metformin monotherapy (MM) failure in a real-world type 2 diabetes mellitus (T2DM) cohort.

Research Design And Methods: Using the IQVIA Electronic Medical Record (formerly GE Centricity) database, adults with T2DM who initiated MM between January 1, 2012 and June 30, 2016 and achieved glycemic control (hemoglobin A1c (HbA1c) <7% (53 mmol/mol); index date) were analyzed. Secondary MM failure was defined in two ways: loss of glycemic control (HbA1c ≥7% (53 mmol/mol)) and treatment change (addition or switch of antihyperglycemic agent).

The optical properties of plasmonic nanoparticle ensembles are determined not only by the particle shape and size but also by the nanoantenna arrangement. To investigate the influence of the spatial ordering on the far-field optical properties of nanoparticle ensembles, we introduce a disorder model that encompasses both "frozen-phonon" and correlated disorder. We present experimental as well as computational approaches to gain a better understanding of the impact of disorder.

Article Synopsis
  • Nonylphenol (NP) is an endocrine disruptor commonly found in the environment and used in making certain detergents and chemicals, but human data on its metabolites are limited.
  • A new analytical method has been developed to accurately measure OH-NP and oxo-NP, oxidized forms of NP, in human urine, using advanced chromatography and mass spectrometry techniques.
  • Despite regulations in the EU, both metabolites were detected in a significant percentage of urine samples from the German population, indicating their potential as biomarkers for monitoring NP exposure in future studies.

Article Synopsis
  • Computational tools are increasingly used to identify biological targets of natural products with anticancer effects, particularly the natural product piperlongumine (PL), which interacts with the hTRPV2 channel.
  • Cryo-electron microscopy revealed how PL binds to an allosteric pocket of the rat TRPV2 channel, showcasing a novel anticancer mechanism against glioblastoma (GBM), where the hTRPV2 channel is overexpressed.
  • Research demonstrated that downregulating hTRPV2 decreases sensitivity to PL, and treating GBM in mouse models with PL formulated in a scaffold significantly reduced tumor growth and improved survival, suggesting a new approach for cancer treatment.

Myelin insulates neuronal axons and enables fast signal transmission, constituting a key component of brain development, aging and disease. Yet, myelin-specific imaging of macroscopic samples remains a challenge. Here, we exploit myelin's nanostructural periodicity, and use small-angle X-ray scattering tensor tomography (SAXS-TT) to simultaneously quantify myelin levels, nanostructural integrity and axon orientations in nervous tissue.

Article Synopsis
  • The study aimed to see if performance on the anti-saccade task (AST) after a first dose of methylphenidate (MPH) could predict clinical outcomes in adults with ADHD.
  • Ninety-seven adults with drug-naive ADHD were tested at baseline, after the first MPH dose, and six months into treatment; results showed ADHD patients had slower reaction times and more mistakes than healthy controls.
  • Findings revealed that improved AST performance (lower direction error percentage) after the first MPH dose could predict remission at six months, indicating that MPH effectively enhances motor planning and response inhibition in adults with ADHD.

Phosphorus (P) is an essential macronutrient for plants, but also a limited resource worldwide. Strict regulations for fertilizer applications in the European Union are a consequence of the negative environmental effects in case of improper use. Maize is typically grown with the application of P starter fertilizer, which, however, might be reduced or even omitted if suitable varieties were available.

If the United Nations system is to remain relevant, or even survive, the thinking to re-imagine and redesign contemporary global governance will come from the Third UN. This article focuses on the ecology of supportive non-state actors - intellectuals, scholars, consultants, think tanks, NGOs, the for-profit private sector, and the media - that interacts with the intergovernmental machinery of the First UN and international civil servants of the Second UN to formulate and refine ideas and decision-making in policy processes. Despite the growth in analyses of non-state actors in global governance, the 'other' or 'Third' UN is poorly understood, often ignored, and normally discounted.

We demonstrate how to reduce the loss in photonic bandgap fibers by orders of magnitude by varying the radius of the corner strands in the core surround. As a fundamental working principle we find that changing the corner strand radius can lead to backscattering of light into the fiber core. Selecting an optimal corner strand radius can thus reduce the loss of the fundamental core mode in a specific wavelength range by almost two orders of magnitude when compared to an unmodified cladding structure.

Members of the transforming growth factor (TGF)-β superfamily play a key role in the regulation of the malignant phenotype of glioblastoma by promoting invasiveness, angiogenesis, immunosuppression, and maintaining stem cell-like properties. Betaglycan, a TGF-β coreceptor also known as TGF-β receptor III (TβRIII), interacts with members of the TGF-β superfamily and acts as membrane-associated or shed molecule. Shed, soluble TβRIII (sTβRIII) is produced upon ectodomain cleavage of the membrane-bound form.

Numerous studies showed the effect of negative affective and pain-related semantic primes enhancing the perceived intensity of successive painful stimuli. It remains unclear whether and how painful primes are able to influence semantic stimuli in a similar way. Therefore, we investigated the effects of noxious primes on the perception of the valence of subsequent semantic stimuli.

Article Synopsis
  • Di-n-butyl adipate (DnBA) serves as a plasticizer and an alternative to the endocrine disruptor di-n-butyl phthalate, being used in various consumer products, including personal care items.
  • A study involving three volunteers measured how DnBA is metabolized and excreted post oral and dermal dosage, analyzing urine samples for specific metabolites over a set period.
  • The findings indicated that certain metabolites, especially mono-n-butyl adipate and 3-hydroxy-mono-n-butyl adipate, could serve as reliable exposure biomarkers for DnBA, though overall metabolite excretion was low and consistent across participants.
