A Proposal for Revised and Simplified Renal Pelvic Urothelial Carcinoma Staging Criteria: A Clinicopathologic Study of 141 Tumors.

Staging of renal pelvic urothelial carcinoma can be challenging due to anatomic variation at the renal pelvis compared with ureter and bladder and calls into question the prognostic accuracy of the current TNM staging. In this study, we determined staging and cancer-specific survival (CSS) in 141 patients undergoing nephroureterectomy for renal pelvic urothelial carcinoma (pTa=50, pT1=29, pT2=10, pT3=36, and pT4=16). Under current staging criteria, we found no significant difference in CSS between adjacent staging categories step-wise across pTa, pT1, pT2, and pT3 tumors.

Oncogenic RARγ isoforms promote head and neck cancer proliferation through vinexin-β-mediated cell cycle acceleration and autocrine activation of EGFR signal.

Results of retinoid-based therapies in head and neck cancer (HNC) are generally disappointing, indicating a lack of understanding of retinoic acid signaling. The role of retinoic acid receptor gamma (RARγ) and its isoforms in HNC is yet to be established. In this study, we found that RARγ1, 2, 4 are the predominant RARγ isoforms expressed in various types of human cancers, including HNC.

Fast STEM image simulation in low-energy transmission electron microscopy by the accurate Chen-van-Dyck multislice method.

The Chen-van-Dyck (CVD) formulation as a rigorous numerical solution to the Schrödinger equation has been demonstrated being the only accurate multislice method for calculating diffraction and imaging in low-energy transmission electron microscopy. The CVD formulation not only considers the forward scattering effects but also includes the backscattering effects. However, since its numerical computation has to be performed in real-space, the CVD method may suffer from divergence and inefficiency in computing time, especially when used for low-energy scanning transmission electron microscopy (STEM) image simulation.

Success rates and success stories: Staging anticipation on fertility clinic websites in Taiwan, Japan, and the UK.

This paper investigates how fertility clinics stage anticipation on their websites to create imagined futures for their potential users. We developed an analytical framework to explore their "tools of futuring," focusing on two key modes: probabilistic and interpretative. This framework helps identify the strategies used by clinics to convey specific visions of assisted reproductive technologies (ARTs).

Improving Time to Completion of Medical Student Clerkship Evaluations.

Background And Objectives: Medical student clinical clerkship evaluations provide feedback for growth and contribute to the clerkship grade and the student's residency application. Their importance is expected to increase even more with the recent change of the US Medical Licensing Examination Step 1 to a pass/fail designation. Timely completion of medical student clerkship evaluations is a problem.

Evaluation of a Telemonitoring System Using Electronic National Early Warning Scores for Patients Receiving Medical Home Care: Pilot Implementation Study.

Background: Telehealth programs and wearable sensors that enable patients to monitor their vital signs have expanded due to the COVID-19 pandemic. The electronic National Early Warning Score (e-NEWS) system helps identify and respond to acute illness.

Objective: This study aimed to implement and evaluate a comprehensive telehealth system to monitor vital signs using e-NEWS for patients receiving integrated home-based medical care (iHBMC).

Interactive effects of rhizospheric soil microbes and litter on the growth of the invasive hyperaccumulator in cadmium-contaminated soil.

Both rhizospheric soil microbes and shoot litter input can have profound effects on plant performance; however, their interactive effects on plants in Cd-contaminated soils remain poorly understood. We grew an invasive hyperaccumulator, , in sterilized and unsterilized rhizosphere soil without litter or with a low (0.2%, dry weight ratio) or a high amount (1%) of litter from in soil with low (5 mg kg) or high (10 mg kg) concentrations of Cd.

Design, Synthesis, and Activity Evaluation of C-23-Modified 5--Mycaminosyltylonolide Derivatives.

The widespread use of tylosin family drugs in clinical practice has led to bacterial resistance and reduced therapeutic efficacy. We designed and synthesized a series of new semisynthetic derivatives of tylosin with 5--mycaminosyltylonolide as the mother nucleus, mainly by introducing a variety of amino groups at its C-23 position. Some of the compounds showed high antibacterial activity against Gram-negative and Gram-positive bacteria.

A critical approach to research on perioperative pain management.

Optimal postoperative pain management is a prerequisite for enhancing functional recovery after surgery. However, many studies assessing analgesic interventions have limitations. Consequently, further improvements in study design are urgently needed.

Salidroside ameliorates diabetic retinopathy and Müller cell inflammation via the PI3K/Akt/GSK-3β/NF-𝜅B pathway.

Purpose: To determine whether salidroside (SAL) modulates inflammatory cytokines in rat retinal Müller cells (rMC-1) in a hyperglycemic environment by investigating the anti-inflammatory mechanisms of SAL in vitro and in vivo.

Methods: A streptozotocin (STZ)-induced diabetic rat model was established to examine the effects of SAL using hematoxylin and eosin (H&E) staining and immunohistochemistry. rMC-1 cells were grown in 50 mM of high-glucose medium.

Practice Advisory for Postoperative Pain Management of Cardiac Surgical Patients: Executive Summary. A Report From the Society of Cardiovascular Anesthesiologists.

Cardiac surgery is associated with significant postoperative pain that can affect patients' recovery and quality of life. Optimal analgesia after cardiac surgery can be challenging due to patients' coexisting morbidities and frequently observed adverse effects when opioids are used to treat postoperative pain. In this current era of enhanced recovery and fast track extubation, the use of multimodal analgesia for pain management after cardiac surgery is expanding.

Role of the insula in rTMS response for depression.

Background: The insula has a significant impact on interoception and depression. This study aims to explore the role of the insula in mediating treatment responses to high-frequency repetitive transcranial magnetic stimulation (rTMS) targeting the left dorsolateral prefrontal cortex (DLPFC).

Methods: Twenty-five patients with either bipolar disorder (BD, n = 15) or major depressive disorder (MDD, n = 10) were recruited.

The Effect of Pre-Exercise Caffeine and Glucose Ingestion on Endurance Capacity in Hypoxia: A Double-Blind Crossover Trial.

The impact of caffeine and glucose supplementation in a hypoxic environment on endurance exercise performance remains inconclusive. The current study examined the effect of pre-exercise carbohydrate and caffeine supplementation on endurance exercise performance in an acute hypoxic environment. Eight healthy active young males participated in this double-blind, within-subjects crossover study.

Endosomes serve as signaling platforms for RIG-I ubiquitination and activation.

RIG-I-like receptors (RLRs) are cytosolic RNA sensors critical for antiviral immunity. RLR activation is regulated by polyubiquitination and oligomerization following RNA binding. Yet, little is known about how RLRs exploit subcellular organelles to facilitate their posttranslational modifications and activation.

Multinucleated tumor cells and micropapillary morphology appear to be predictors of poor prognosis in renal cell carcinoma with papillary and oncocytic features.

Renal cell carcinoma with papillary and oncocytic features (RCC-PO) are poorly understood, partially due to conflicting results in multiple studies. The histological features that predict behavior of RCC-PO have not been elucidated. The aim is to review clinicopathologic features and to correlate clinical outcomes of patients with RCC-PO to further expand our knowledge on these heterogeneous tumors.

The Neural Correlations of Olfactory Associative Reward Memories in .

Advancing treatment to resolve human cognitive disorders requires a comprehensive understanding of the molecular signaling pathways underlying learning and memory. While most organ systems evolved to maintain homeostasis, the brain developed the capacity to perceive and adapt to environmental stimuli through the continuous modification of interactions within a gene network functioning within a broader neural network. This distinctive characteristic enables significant neural plasticity, but complicates experimental investigations.
