CLEFT: Language-Image Contrastive Learning with Efficient Large Language Model and Prompt Fine-Tuning.

Recent advancements in Contrastive Language-Image Pre-training (CLIP) [21] have demonstrated notable success in self-supervised representation learning across various tasks. However, the existing CLIP-like approaches often demand extensive GPU resources and prolonged training times due to the considerable size of the model and dataset, making them poor for medical applications, in which large datasets are not always common. Meanwhile, the language model prompts are mainly manually derived from labels tied to images, potentially overlooking the richness of information within training samples.

Using XBGoost, an interpretable machine learning model, for diagnosing prostate cancer in patients with PSA < 20 ng/ml based on the PSAMR indicator.

To create a diagnostic tool before biopsy for patients with prostate-specific antigen (PSA) levels < 20 ng/ml to minimize prostate biopsy-related discomfort and risks. Data from 655 patients who underwent transperineal prostate biopsy at the First Affiliated Hospital of Wannan Medical College from July 2021 to January 2023 were collected and analyzed. After applying the Synthetic Minority Over-sampling TEchnique class balancing on the training set, multiple machine learning models were constructed by using the Least Absolute Shrinkage and Selection Operator (LASSO) feature selection to identify the significant variables.

This study explores motor cortex stimulation (MCS) as a treatment for Ramsay Hunt syndrome (RHS)-related neuralgia, which often persists despite traditional therapies. A 68-year-old patient with RHS experienced significant pain and sensory relief after MCS, after ineffective conventional treatments. MCS enhances neural plasticity, offering a promising alternative for managing intractable neuralgia and sensory disturbances in RHS patients.

Nth Slice Eraser: An Automated Algorithm to Ease Editing Workflow of Organ Contours Generated by Artificial Intelligence.

The time-consuming process of manual contouring of healthy tissue and organs in radiation therapy has prompted the development of computational systems to aid and automate this process, such as artificial intelligence (AI) segmentation and interpolation algorithms. These algorithms are useful in saving time, however, they are not always accurate. Fixing such inaccuracies by editing contours is a manual, time-consuming process as no 'undo' feature currently exists in the most commonly used treatment planning system (TPS).

More marginalization, less career development? Linking marginalization profiles to decent work among rural teachers.

Using Latent Profile Analysis, this study explored the connections between different marginalization profiles and perceptions of decent work among rural primary school teachers in China. Analyzing data from 443 teachers across seven rural primary schools in Fujian Province, we discerned three unique marginalization profiles: Robust Adapters (n = 182, 41 %), Challenge Facers (n = 210, 47 %), and Conditioned Survivors (n = 51, 12 %). These profiles were examined for their links to decent work dimensions.

Bromocriptine mesylate-loaded nanoparticles co-modified with low molecular weight protamine and lactoferrin for enhanced nose-to-brain delivery in Parkinson's disease treatment.

Parkinson's disease confronts challenges in drug delivery due to the blood-brain barrier. Intranasal delivery bypasses the blood-brain barrier for improved drug bioavailability, yet narrow nasal space and brief retention time hinder clinical applicability. We conducted a Bromocriptine Mesylate-loaded PLGA nanoparticles co-modified with low molecular weight protamine (LMWP) and lactoferrin (Lf) (LMWP/Lf-BCM-NPs) for nose-to-brain delivery.

Bandlike charge transport and electron-phonon coupling in organic molecular crystals.

Charge transport is important in organic molecular crystals (OMCs), where high carrier mobilities are desirable for a range of applications. However, modeling and predicting the mobility is chal- lenging in OMCs due to their complex crystal and electronic structures and electron-phonon (e-ph) interactions. Here we show accurate first-principles calculations of electron and hole carrier mobility in several OMCs: benzene, anthracene, tetracene, pentacene, and biphenyl.
