This paper presents preliminary work on a method to increase the number of detection channels of a commercial 6-channel spectrometric sensor, by employing a set of multiplexed spectrally colored illumination sources. A demonstrator has been built and tested on a set of independent dyes. The results suggest successful enhancement of the number of detection channels. More tests are needed to provide quantitative performance evaluation, and to demonstrate viability in a clinical setting. Clinical Relevance- The technique presented in this paper shows promise to provide a viable method for multispectral sensing in highly-miniaturized systems such as in-vivo sensing capsules.

Background: Growth hormone (GH) could improve the outcomes of fertilization and embryo transfer (IVF-ET) in patients with decreased ovarian reserve (DOR), but which age group will benefit the most has remained controversial. This study aims to explore the outcome of IVF-ET among differently aged patients with DOR treated with GH.
Methods: A total of 846 patients with DOR undergoing IVF-ET from May 2018 to June 2023 at the Reproductive Medicine Center of Sichuan Provincial Women's and Children's Hospital were prospectively enrolled.

Background: Programmed cell death plays an important role in neuronal injury and death after ischemic stroke (IS), leading to cellular glucose deficiency. Glucose deficiency can cause abnormal accumulation of cytotoxic disulfides, resulting in disulfidptosis. Ferroptosis, apoptosis, necroptosis, and autophagy inhibitors cannot inhibit this novel programmed cell death mechanism.

Accurate building segmentation has become critical in various fields such as urban management, urban planning, mapping, and navigation. With the increasing diversity in the number, size, and shape of buildings, convolutional neural networks have been used to segment and extract buildings from such images, resulting in increased efficiency and utilization of image features. We propose a building semantic segmentation method to improve the traditional Unet convolutional neural network by integrating attention mechanism and boundary detection.

Background: Bone marrow (BM) in addition to being the origin of primary hematological malignancies is also commonly involved in metastatic solid tumors. Bone marrow examination includes aspiration and biopsy, and it is a well-known procedure not only to diagnose hematological malignancies but also for staging and prognosis of various solid tumors. The presence of metastasis in the bone marrow is of grave prognostic significance and it is imperative to rule out marrow involvement in any malignancy where curative treatment is considered.
