Domain Generalization-based Medical Image Segmentation (DGMIS) aims to enhance the robustness of segmentation models on unseen target domains by learning from fully annotated data across multiple source domains. Despite the progress made by traditional DGMIS methods, they still face several challenges. First, most DGMIS approaches rely on static models to perform inference on unseen target domains, lacking the ability to dynamically adapt to samples from different target domains.

Granzymes (Gzms), a family of serine proteases, expressed by immune and nonimmune cells, present perforin-dependent and independent intracellular and extracellular functions. When released in the extracellular space, GzmA, with trypsin-like activity, is involved in the pathophysiology of different inflammatory diseases. However, there are no validated specific systems to detect active forms of extracellular GzmA, making it difficult to assess its biological relevance and potential use as a biomarker.

Current near-infrared organic photosensitizers are built from large and non-modular structures that cannot be tuned to improve safety and minimize off-target toxicity. This work describes a novel chemical platform to generate enzyme-activatable near-infrared photosensitizers.

Objective: To explore the efficacy and safety of bortezomib or thalidomide combined with recombinant human erythropoietin (rhEPO) in the treatment of multiple myeloma (MM).
Methods: A total of 80 patients with MM who were treated in the Second People's Hospital of Wuhu from January 2013 to December 2018 were selected as the research subjects, and they were divided into bortezomib group (=40) and thalidomide group (=40) by the simple randomization method. The bortezomib group received bortezomib regimen combined with rhEPO therapy, and the thalidomide group was given thalidomide regimen combined with rhEPO therapy, and all patients were treated for 3 courses with every 3 weeks as a course of treatment.
Purpose: Segmentation of orbital tumors in CT images is of great significance for orbital tumor diagnosis, which is one of the most prevalent diseases of the eye. However, the large variety of tumor sizes and shapes makes the segmentation task very challenging, especially when the available annotation data is limited.
Methods: To this end, in this paper, we propose a multi-scale consistent self-training network (MSCINet) for semi-supervised orbital tumor segmentation.
During the COVID-19 pandemic, several governments tried to contain the spread of SARS-CoV-2, the virus that causes COVID-19, with lockdowns that prohibited leaving one's residence unless carrying out a few essential services. We investigate the relationship between limitations to mobility and mental health in the UK during the first year and a half of the pandemic using a unique combination of high-frequency mobility data from Google and monthly longitudinal data collected through the Understanding Society survey. We find a strong and statistically robust correlation between mobility data and mental health survey data and show that increased residential stationarity is associated with the deterioration of mental wellbeing even when regional COVID-19 prevalence and lockdown stringency are controlled for.

This study aimed to quantify and decompose the changes in life expectancy during 2019-2023 and corresponding age and gender disparities in 27 countries.
Methods: Data were sourced from the Human Mortality Database, the World Population Prospects 2022 and the United Kingdom's Office for National Statistics.
Background: The protein tyrosine phosphatase H receptor (PTPRH) is known to regulate the occurrence and development of pancreatic and colorectal cancer. However, its association with glycolysis in non-small cell lung cancer (NSCLC) is still unclear. In this study, we aimed to investigate the relationship between PTPRH expression and glucose metabolism and the underlying mechanism of action.

AP000695.2 is a novel long non-coding RNA (lncRNA). Its aberrant high expression is remarkably associated with poor prognosis of patients with lung adenocarcinoma (LUAD).
View Article and Find Full Text PDFImmunotherapy is an emerging antitumor modality with high specificity and persistence, but its application for resected tumor treatment is impeded by the low availability of tumor-specific antigens and strong immunosuppression in the wound margin. Here a nanoengineered hydrogel is developed for eliciting robust cooperative ferroptosis-immunotherapeutic effect on resected tumors. Specifically, β-cyclodextrin (β-CD) is first grafted onto oxidized sodium alginate (OSA) through Schiff base ligation, which could trap cRGD-modified redox-responsive Withaferin prodrugs (WA-cRGD) to obtain the hydrogel building blocks (Gel@WA-cRGD).

Objective: We examine the wellbeing and outcomes of children with and without disabilities in OOHC.
The expected year-on-year intrinsic mortality variations/changes are largely overlooked in the existing research when estimating the effect of the COVID-19 pandemic on mortality patterns. To fill this gap, this study provides a new assessment of the loss of life expectancy caused by COVID-19 in 27 countries considering both the actual and the expected changes in life expectancy between 2019 and 2020. Life expectancy in 2020 and the expected life expectancy in the absence of COVID-19 are estimated using the Lee-Carter model and data primarily from the Human Mortality Database.

Cytotoxic immune cells, including T lymphocytes (CTLs) and natural killer (NK) cells, are essential components of the host response against tumors. CTLs and NK cells secrete granzyme A (GzmA) upon recognition of cancer cells; however, there are very few tools that can detect physiological levels of active GzmA with high spatiotemporal resolution. Herein, we report the rational design of the near-infrared fluorogenic substrates for human GzmA and mouse GzmA.

A 65-year-old man with prostate cancer underwent 18 F-prostate-specific membrane antigen (PSMA) PET/CT for staging. Intense 18 F-PSMA uptake occurred at the primary lesion, bladder, adjacent seminal vesicle, and rectum.
