Influence of prosthetic foot selection on walking performance during various load carriage conditions.

Background: Ambulatory individuals with lower limb amputations often face challenges with body support, body propulsion, and balance control. Carrying an infant, toddler, backpack, or other load can exacerbate these challenges and highlights the importance of prescribing the most suitable prosthetic foot. The aim of this study was to examine the influence of five different prosthetic feet on walking performance during various load carriage conditions.

Binding a C-appended rhenium-(Bispyridine) carbonyl complex to β-Lactoglobulin: Effects of pH & cysteine modification on calyx affinity.

Due to its commercial availability and well-defined structure, the interaction between bovine protein β-lactoglobulin (βLG) and a wide variety of non-native ligands - including transition metal complexes - has been explored, but its application as an artificial metalloenzyme scaffold is limited. This protein is hypothesized to transport fatty acids and other nutrients during juvenile development, and it binds hydrophobic ligands inside a binding pocket constructed upon an 8-stranded β-barrel, called the 'calyx'. Herein, we compare the binding behavior of two rhenium(anthracene-bispyridine) ('Anth-py') tricarbonyl complexes, one with a 12‑carbon chain appended to the ligand scaffold ('Anth-py') to βLG.

Targeting Metabolic and Epigenetic Vulnerabilities in Glioblastoma with SN-38 and Rabusertib Combination Therapy.

Glioblastoma (GBM), the most prevalent primary malignant brain tumor, remains challenging to treat due to extensive inter- and intra-tumor heterogeneity. This variability demands combination treatments to improve therapeutic outcomes. A significant obstacle in treating GBM is the expression of O-methylguanine-DNA methyltransferase, a DNA repair enzyme that reduces the efficacy of the standard alkylating agent, temozolomide, in about 50% of patients.

Metabolic dependency mapping identifies Peroxiredoxin 1 as a driver of resistance to ATM inhibition.

Metabolic pathways fuel tumor progression and resistance to stress conditions including chemotherapeutic drugs, such as DNA damage response (DDR) inhibitors. Yet, significant gaps persist in how metabolic pathways confer resistance to DDR inhibition in cancer cells. Here, we employed a metabolism-focused CRISPR knockout screen and identified genetic vulnerabilities to DDR inhibitors.

Representational geometry explains puzzling error distributions in behavioral tasks.

Measuring and interpreting errors in behavioral tasks is critical for understanding cognition. Conventional wisdom assumes that encoding/decoding errors for continuous variables in behavioral tasks should naturally have Gaussian distributions, so that deviations from normality in the empirical data indicate the presence of more complex sources of noise. This line of reasoning has been central for prior research on working memory.

Variants in the SOX9 transactivation middle domain induce axial skeleton dysplasia and scoliosis.

SOX9 is a crucial transcriptional regulator of cartilage development and homeostasis. Dysregulation of is associated with a wide spectrum of skeletal disorders, including campomelic dysplasia, acampomelic campomelic dysplasia, and scoliosis. Yet how variants contribute to the spectrum of axial skeletal disorders is not well understood.

Purpose: Cancer-related cognitive impairment (CRCI) can have a profound impact on the lives of cancer survivors. A multitude of subjective and objective assessment tools exist to assess the presence and severity of CRCI. However, no purpose-built tool exists to assess the unmet needs of cancer survivors directly relating to CRCI.

Addressing Health-Related Social Needs During COVID-19 Through a Hospital-Based, Community Health Worker Program: A Case Study.

. Despite accounting for 34% of the population in Austin, Texas, Latinx individuals made up 50% of those who tested positive for coronavirus, 54% of COVID-related hospitalizations, and 51% of COVID-related deaths between March and June 2020. Of hospitalized Latinx patients, 40% had never seen a primary care provider and many had undiagnosed health conditions.

QM Investigation of Rare Earth Ion Interactions with First Hydration Shell Waters and Protein-Based Coordination Models.

Conventional methods for extracting rare earth metals (REMs) from mined mineral ores are inefficient, expensive, and environmentally damaging. Recent discovery of lanmodulin (LanM), a protein that coordinates REMs with high-affinity and selectivity over competing ions, provides inspiration for new REM refinement methods. Here, we used quantum mechanical (QM) methods to investigate trivalent lanthanide cation (Ln) interactions with coordination systems representing bulk solvent water and protein binding sites.

Gradient Design with Low-tortuosity Overcoming Kinetic Limitations in High-Loading Solid-State Cathodes.

The extensive commercialization of practical solid-state batteries (SSBs) necessitates the development of high-loading solid-state cathodes with fast charging capability. However, electrochemical kinetics are severely delayed in thick cathodes due to tortuous ion transport pathways and slow solid-solid ion diffusion, which limit the achievable capacity of SSBs at high current densities. In this work, we propose a conductivity gradient cathode with low-tortuosity to enable facile ion transport and counterbalance ion concentration gradient, thereby overcoming the kinetic limitations and achieving fast charging capabilities in thick cathodes.

Marine heatwaves imperil emblematic reef fishes by altering the energetic landscape of coral reefs.

Marine heatwaves are increasingly common due to human-induced climate change. Under prolonged thermal stress on coral reefs, corals can undergo bleaching, leading to mass coral mortality and large-scale changes in benthic community composition. While coral mortality has clear, negative impacts on the body condition and populations of coral-dependent fish species, the mechanisms that drive these changes remain poorly resolved.

Antibiotic susceptibility testing using minimum inhibitory concentration (MIC) assays.

Antimicrobial resistance is due to genetic changes that allow bacteria to evade antibiotic treatment. Antimicrobial susceptibility testing is critical for the detection of antibiotic-resistant strains, the selection of effective therapeutic strategies against bacterial infections, and the evaluation of the efficacy of novel antimicrobials. Among the variety of clinical microbiology methods used for antibiotic susceptibility testing, minimum inhibitory concentration (MIC) assays have become the gold standard in clinical practice.

The cost-effectiveness of vaccination against COVID-19 illness during the initial year of vaccination.

Preventing inappropriate signals pre- and post-ligand perception by a toggle switch mechanism of ERECTA.

Dynamic control of signaling events requires swift regulation of receptors at an active state. By focusing on the Arabidopsis ERECTA (ER) receptor kinase, which perceives peptide ligands to control multiple developmental processes, we report a mechanism preventing inappropriate receptor activity. The ER C-terminal tail (ER_CT) functions as an autoinhibitory domain: Its removal confers higher kinase activity and hyperactivity during inflorescence and stomatal development.

Obesity, dietary interventions and microbiome alterations in the development and progression of prostate cancer.

Purpose Of Review: The role of the microbiome in prostate cancer is an emerging subject of research interest. Certain lifestyle factors, such as obesity and diet, can also impact the microbiome, which has been implicated in many diseases, such as heart disease and diabetes. However, this link has yet to be explored in detail in the context of prostate cancer.

Reliability of Central Vein Sign Imaging With 3T FLAIR* in a Multicenter Study.

Background And Purpose: The central vein sign (CVS) is a diagnostic imaging biomarker for multiple sclerosis (MS). FLAIR* is a combined MRI contrast that provides high conspicuity for CVS at 3 Tesla (3T), enabling its sensitive and accurate detection in clinical settings. This study evaluated whether CVS conspicuity of 3T FLAIR* is reliable across imaging sites and MRI vendors and whether gadolinium (Gd) contrast increases CVS conspicuity.

Manipulating Fano Coupling in an Opto-Thermoelectric Field.

Fano resonances in photonics arise from the coupling and interference between two resonant modes in structures with broken symmetry. They feature an uneven and narrow and tunable lineshape and are ideally suited for optical spectroscopy. Many Fano resonance structures have been suggested in nanophotonics over the last ten years, but reconfigurability and tailored design remain challenging.

Using Multiple Anthropomorphic Measures to Estimate Height in Muscular Dystrophies and Its Impact on Lung Function.

Background: An accurate height estimate is important for assessing pulmonary function, and body mass index. If a patient cannot stand, an accurate standing height cannot be directly measured. Knee-heel length, arm span, ulnar length, and tibial length have been studied in otherwise healthy populations as single measurements for height estimation.

Mu opioid receptors expressed in striatal D2 medium spiny neurons have divergent contributions to cocaine and morphine reward.

While our understanding of the neurobiological mechanisms underlying cocaine and opiate reward has historically been dopamine-focused, evidence from genetic and pharmacological approaches indicates that µ-opioid receptors (MORs) in the striatum are important contributors. Within the striatum, MORs are expressed in both dopamine D1-receptor and D2-receptor expressing GABAergic medium spiny neurons (MSNs), as well as in interneurons and various afferents. Thus, it remains unclear how these distinct MOR populations regulate drug reward.
