Fertility preservation in young breast cancer patients: A nationwide survey on knowledge, attitudes, and practices among breast surgical healthcare providers in China.

Purpose: Fertility preservation (FP) is a critical concern for young breast cancer (YBC) patients receiving gonadotoxic treatments. Breast surgical healthcare providers (HCPs) play a pivotal role in discussing FP options and facilitating timely referrals. This study aimed to assess the knowledge, attitudes, and practices of breast surgical HCPs in China regarding FP, identify barriers to FP discussions, and examine factors influencing referral practices.

Lattice plainification and band engineering lead to high thermoelectric cooling and power generation in n-type BiTe with mass production.

Thermoelectrics can mutually convert between thermal and electrical energy, ensuring its utilization in both power generation and solid-state cooling. BiTe exhibits promising room-temperature performance, making it the sole commercially available thermoelectrics to date. Guided by the lattice plainification strategy, we introduce trace amounts of Cu into n-type Bi(Te, Se) (BTS) to occupy Bi vacancies, thereby simultaneously weakening defect scattering and modulating the electronic bands.

Shape-controlled asymmetric bowl-like PDA@Au substrates for sensitive SERS detection of anabolic androgenic steroids.

The widespread accumulation of androgenic steroid endocrine disruptors in water and food has garnered increasing attention due to their significant risks to ecosystems and human health. These steroids, which cannot be completely eliminated, highlight the urgent need for advanced detection technologies. In this study, we present a novel emulsion-induced interface-anisotropic assembly strategy to synthesize bowl-like mesoporous polydopamine (PDA) particles, which exhibit high sensitivity in surface-enhanced Raman scattering (SERS) detection.

Analysis of the efficacy of Langhans giant cells in controlling cutaneous Mycobacterium marinum infections.

Investigation of Separating Temperature-Induced Structural Strain Using Improved Blind Source Separation (BSS) Technique.

The strain data acquired from structural health monitoring (SHM) systems of large-span bridges are often contaminated by a mixture of temperature-induced and vehicle-induced strain components, thereby complicating the assessment of bridge health. Existing approaches for isolating temperature-induced strains predominantly rely on statistical temperature-strain models, which can be significantly influenced by arbitrarily chosen parameters, thereby undermining the accuracy of the results. Additionally, signal processing techniques, including empirical mode decomposition (EMD) and others, frequently yield unstable outcomes when confronted with nonlinear strain signals.

Comprehensive transcriptomic analysis identifies three distinct subtypes of pituitary adenomas: insights into tumor behavior, prognosis, and stem cell characteristics.

Background: Pituitary adenomas (PAs) are the second most common intracranial tumor. While current diagnostic practices rely primarily on histological testing, they often fail to capture the molecular complexities of pituitary adenomas, underscoring the need for a molecular-based classification to refine therapeutic strategies and prognostic assessments. This study aims to provide a molecularly unbiased classification of pituitary adenomas and explore their unique gene expression patterns and clinical features.

A portable hydrogel kit based on Au@GM88A/I combined with mobile phone for polychromatic semi-quantitative and quantitative sensing analysis.

Endoplasmic reticulum stress and therapeutic strategies in metabolic, neurodegenerative diseases and cancer.

The accumulation of unfolded or misfolded proteins within the endoplasmic reticulum (ER), due to genetic determinants and extrinsic environmental factors, leads to endoplasmic reticulum stress (ER stress). As ER stress ensues, the unfolded protein response (UPR), comprising three signaling pathways-inositol-requiring enzyme 1, protein kinase R-like endoplasmic reticulum kinase, and activating transcription factor 6 promptly activates to enhance the ER's protein-folding capacity and restore ER homeostasis. However, prolonged ER stress levels propels the UPR towards cellular demise and the subsequent inflammatory cascade, contributing to the development of human diseases, including cancer, neurodegenerative disorders, and diabetes.
