PC-YOLO11s: A Lightweight and Effective Feature Extraction Method for Small Target Image Detection.

Compared with conventional targets, small objects often face challenges such as smaller size, lower resolution, weaker contrast, and more background interference, making their detection more difficult. To address this issue, this paper proposes an improved small object detection method based on the YOLO11 model-PC-YOLO11s. The core innovation of PC-YOLO11s lies in the optimization of the detection network structure, which includes the following aspects: Firstly, PC-YOLO11s has adjusted the hierarchical structure of the detection network and added a P2 layer specifically for small object detection.

Transurethral resection of bladder tumor with Bacille Calmette-Guerin intravesical instillation for HRNMIBC and factors influencing recurrence.

Objective: To investigate the effectiveness of combining transurethral resection of bladder tumor (TURBT) with Bacille Calmette-Guerin (BCG) intravesical instillation in treating high-risk non-muscle invasive bladder cancer (HRNMIBC).

Methods: We retrospectively reviewed the clinical data from 118 HRNMIBC patients treated at Tongren Hospital between March 2020 and June 2022. The patients were categorized into two groups based on their treatment regimen: the control group (n=60) which received regular pirarubicin intravesical instillation, and the observation group (n=58) which received additional BCG intravesical instillation alongside pirarubicin.

The therapeutic effects of theta burst stimulation on negative symptoms in chronic schizophrenia using functional near-infrared spectroscopy.

Background: To explore the efficacy of theta burst stimulation (TBS) on the negative symptoms in patients with chronic schizophrenia, and to investigate the alterations of local brain activity using functional near-infrared spectroscopy (fNIRS).

Methods: 100 patients with chronic schizophrenia were enrolled and divided into the real group (50 subjects) and sham group (50 subjects). The real group was given real stimulation of TBS for 4 weeks, and the sham group was sham-stimulated with the same site.

Preparation and cell imaging of a nido-carborane fluorescent complex based on multi-component polymerization.

The biocompatibility of carborane was a difficult problem that had drawn a lot of study interest. Using multi-ion inlay binding, water-soluble polymers were created by encapsulating nido-carborane in diazaspirodecaniums such as para-poly-nido-carboanylazaspirodecanium [5,4] (p-PNC54), para-poly-nido-carboanylazaspirodecanium [6,5] (p-PNC65), meta-poly-nido-carboanylazaspirodecanium [5,4] (m-PNC54), and meta-poly-nido-carboanylazaspirodecanium [6,5] (m-PNC65). First, the active control 5-fluorouracil demonstrated strong activity against HeLa and HCT-116 cells but minimal cytotoxicity at 19.

Androgen receptor inhibitors in treating prostate cancer.
