Abstract Photonic integrated circuits (PICs) represent a promising technology for the much-needed medical devices of today. Their primary advantage lies in their ability to integrate multiple functions onto single chip, thereby reducing complexity, size, maintenance requirements, and costs. When applied optical coherence tomography (OCT), leading tool state-of-the-art ophthalmic diagnosis, PICs have potential increase accessibility, especially scenarios, where weight, or costs are limiting factors. In this paper, we present PIC-based CMOS-compatible spectrometer spectral domain OCT with an unprecedented level integration. To achieve this, co-integrated 512-channel arrayed waveguide grating electronics. We successfully addressed challenge establishing connection from waveguides photodiodes monolithically on chip minimal losses achieving coupling efficiency 70%. With fully interfaced system, reached sensitivity 92dB at imaging speed 55kHz, 6dB signal roll-off occurring 2mm. innovative obtain 3D vivo tomograms zebrafish larvae human skin. This ground-breaking represents significant step towards miniaturised, cost-effective, maintenance-free system.

Cancer is a heterogeneous disease. Each individual tumor unique and characterized by structural, cellular, genetic molecular features. Therefore, patient-derived cancer models are indispensable tools in research have been actively introduced into the healthcare system. For instance, provide good reproducibility of susceptibility resistance cells against drugs, allowing personalized therapy for patients. In this article, we review advantages disadvantages following cancer: (1) PDC—patient-derived cell culture, (2) PDS—patient-derived spheroids PDO—patient-derived organoids, (3) PDTSC—patient-derived tissue slice cultures, (4) PDX—patient-derived xenografts, humanized PDX, as well PDXC—PDX-derived cultures PDXO—PDX-derived organoids. We also an overview current clinical investigations new developments area models.

Abstract Glioblastoma (GBM) constitutes the most common primary brain tumor in adults. The challenges GBM therapeutics have shed light on zebrafish used as a promising animal model for preclinical xenograft studies without standardized methodology. This systematic review aims to summarize advances xenografting, compare research protocols pinpoint advantages and underlying limitations, designate predominant xenografting parameters. Based PRISMA checklist, we systematically searched PubMed, Scopus, ZFIN using keywords “glioblastoma,” “xenotransplantation,” “zebrafish” papers published from 2005 2022, available English. 46 articles meeting criteria were examined strain, cancer cell line, labeling technique, injected number, time site of injection, maintenance temperature. Our designated that AB wild-type zebrafish, Casper transparent mutants, transgenic Tg(fli1:EGFP), or crossbreeding these predominate among strains. Orthotopic transplantation is more commonly employed. A number 50–100 cells at 48 h post-fertilization high density low infusion volume considered an effective approach.

The increasing number of available anti-cancer drugs presents a challenge for oncologists, who must choose the most effective treatment patient. Precision cancer medicine relies on matching drug with tumor's molecular profile to optimize therapeutic benefit. However, current precision approaches do not fully account intra-tumoral heterogeneity. Different mutation profiles and cell behaviors within single heterogeneous tumor can significantly impact therapy response patient outcomes. Patient-derived avatar models recapitulate patient's in an animal or dish provide means functionally assess heterogeneity's response. Mouse xenograft organoid avatars are well-established, but time required generate these is practical clinical decision-making. Zebrafish emerging as time-efficient cost-effective model. In this review, we highlight recent developments zebrafish discuss unique features that make them ideal interrogation heterogeneity part pipelines.

Abstract Cancer patients often undergo rounds of trial-and-error to find the most effective treatment because there is no test in clinical practice for predicting therapy response. Here, we conduct a study validate zebrafish patient-derived xenograft model (zAvatar) as fast predictive platform personalized colorectal cancer. zAvatars are generated with patient tumor cells, treated exactly same their corresponding and analyzed at single-cell resolution. By individually comparing responses 55 zAvatar-test, develop decision tree integrating stage, zAvatar-apoptosis, zAvatar-metastatic potential. This accurately forecasts progression 91% accuracy. Importantly, sensitive zAvatar-test exhibit longer progression-free survival compared those resistant test. We propose rapid approach guide decisions, optimizing options improving cancer patients.
