We present a case of extensive spread of high-grade squamous intraepithelial lesion (HSIL)/cervical intraepithelial neoplasia grade 3 (CIN3) with foci of invasive squamous cell carcinoma (SCC) in a premenopausal woman. Superficial spread of CIN3 and cervical SCC to the endometrium and/or fallopian tubes is rare, especially in countries with cervical cancer screening programs. Our case occurred during the COVID-19 pandemic, which may have been a major contributing factor to delayed detection and, consequently extensive spread.

Background: Colorectal cancer (CRC) has emerged as one of the most common cancers, with increasing survival rates globally. As patients with CRC experience diverse treatment effects corresponding to different survival stages, understanding their unmet needs based on the survival stage is critical to tailor supportive care with limited medical resources.
Aim: This study aimed to understand the unmet needs of patients with CRC across survival stages.
High-throughput computational materials discovery has promised significant acceleration of the design and discovery of new materials for many years. Despite a surge in interest and activity, the constraints imposed by large-scale computational resources present a significant bottleneck. Furthermore, examples of very large-scale computational discovery carried out through experimental validation remain scarce, especially for materials with product applicability.

Understanding the diverse electrochemical reactions occurring at electrode-electrolyte interfaces (EEIs) is a critical challenge to developing more efficient energy conversion and storage technologies. Establishing a predictive molecular-level understanding of solid electrolyte interphases (SEIs) is challenging due to the presence of multiple intertwined chemical and electrochemical processes occurring at battery electrodes. Similarly, chemical conversions in reactive electrochemical systems are often influenced by the heterogeneous distribution of active sites, surface defects, and catalyst particle sizes.

Solvation structures of working cations have been recognized as a key component in the design of electrolytes; however, most structure-property correlations of metal ions in organic electrolytes usually build upon favorable static solvation structures, often overlooking solvent exchange dynamics. We here report the ion solvation structures and solvent exchange rates of magnesium electrolytes in various solvents by using multimodal nuclear magnetic resonance (NMR) analysis and molecular dynamics/density functional theory (MD/DFT) calculations.

While the formation of the solid-electrolyte interphase (SEI) on anodes has received much attention, there is still a lack of understanding the formation of the cathode-electrolyte interphase (CEI) on the cathodes. To fill this gap, we report on dynamic deformations on LiFePO cathodes during charge/discharge by utilizing operando digital image correlation, impedance spectroscopy, and cryo X-ray photoelectron spectroscopy.

We do not recommend delaying diagnosis in symptomatic children who meet criteria but when major behavioral changes are reported after diagnosis, reevaluation may be beneficial.

Modulation of condensate dynamics by small molecules has therapeutic potential, but so far, few condensate modulators have been disclosed. The SARS-CoV-2 nucleocapsid (N) protein forms phase-separated condensates that are hypothesized to play critical roles in viral replication, transcription, and packaging, suggesting that N condensation modulators might have anti-coronavirus activity across multiple strains and species.

Here we focus on CROCCP2, a hominid-specific gene duplicate from ciliary rootlet coiled coil (CROCC), also known as rootletin, that encodes the major component of the ciliary rootlet. We find that CROCCP2 is highly expressed in the human fetal brain and not in other primate species.

This extremotolerant behavior has been attributed in part to repetitive, amphipathic, and intrinsically disordered proteins that are upregulated in the protected state. Here, we assemble a library of approximately 300 naturally occurring and designed extremotolerance-associated proteins to assess their ability to protect human cells from chemically induced apoptosis.

A massive demand for palliative care has developed in Vietnam because of the burden of cancer, with more than 70% of patients diagnosed in the terminal stage. Despite the recommended guidelines, palliative nursing in Vietnam has focused mainly on pain management and the treatment of complications. Research is needed to explore the reality of nursing practice and difficulties in palliative nursing.

As a model for this process, and as a potential vehicle for exploitation of its properties, we explore here a synthetic multiphase LLPS system consisting of a mixture of self-assembled DNA particles. The particles, termed "DNA nanostars" (NSs), consist of four double-stranded DNA arms that each terminate in a single-stranded overhang.

Here, we report for the first time the demonstration of quantum walks and localized quantum walks in a new type of optical fibers having a ring of cores constructed with both periodic and quasiperiodic Fibonacci sequences, respectively. Good agreement between theoretical and experimental results has been achieved.

Synthetic biomolecular liquids offer a means to study the mechanisms of this process, as well as offering a route to the creation of functional biomimetic materials. With these goals in mind, we here examine the partitioning of long double-stranded DNA linkers into a liquid composed of small DNA particles ("nanostars") whose phase separation is driven by base pairing.

The proposed Fibonacci arrays of waveguides (FAWs) are simple and straightforward to make, but have a rich set of properties that are of potential use for applications in quantum communication. Our simulations show that, in contrast with randomly disordered AWs, LQWs in FAWs are highly controllable due to the deterministic disorder nature of quasi-periodic systems.

However, current methods are unable to measure the time-dependent mechanics of such systems or map mechanics to the corresponding dynamic macromolecular properties. Here, we present an experimental approach that combines time-resolved optical tweezers microrheology with diffusion-controlled microfluidics to measure the time-evolution of microscale mechanical properties of dynamic systems during triggered activity.

The poly(S-co-DVB) cathode offers scalability owing to the abundance and low cost of DVB. The Li-HC anode, the surface of which is passivated by a solid electrolyte interphase, inhibits the deposition of polysulfides.

Understanding of this process, and the properties of the resulting liquid, has been hampered in typical systems by the complexity of the components and of the intermolecular interactions. Here, we examine a single-component system comprised entirely of DNA, in which tetravalent DNA nanostar particles condense into liquids through attractive bonds formed from basepairing interactions.

Paired with vertebral augmentation of the affected vertebra, patients can often become functional and experience significant pain reduction. However, bone ablation must be paired with various modalities of treatment as it only provides pain relief and local tumor control and does not address systemic metastatic disease.

Surgical resection is the treatment of choice for symptomatic PNSTs and offers patients a potential cure; however, pre-existing conditions or tumor location may limit a patient's surgical options. Radiofrequency ablation (RFA) may provide an alternative therapeutic strategy for the treatment of selected PNSTs that are not amenable to surgical resection.
