Introduction: Although health information is widely available to the Norwegian population a lack of health literacy is still common and considered a public health challenge. However, there is limited information on the health literacy of the adolescent population in Norway. The purpose of this pilot study was to assess health literacy and self-reported health habits among soldiers in basic military training, both in field, camp, and home settings.

Methods: We examined the molecular profile of DCIS by self-reported race (SRR) and outcome groups in Black (n = 99) and White (n = 191) women in a large DCIS case-control cohort study with longitudinal follow up.
Recombinant α-microglobulin (A1M) is proposed as a protector during Lu-octreotate treatment of neuroendocrine tumors, which is currently limited by bone marrow and renal toxicity. Co-administration of Lu-octreotate and A1M could result in a more effective treatment by protecting healthy tissue, but the radioprotective action of A1M is not fully understood. The aim of this study was to examine the proteomic response of kidneys and bone marrow early after Lu-octreotate and/or A1M administration.

Still, accumulation in healthy tissue limits the activity that can be administered. Therefore, fractionated therapy is used to lower toxicity.

Here we explored how the epigenome contributes to matrix metalloprotease (MMP) dysregulation impacting tumor invasion, which is the first step of the metastatic process.
Methods: We combined RNA expression and chromatin interaction data to identify insulator elements potentially associated with MMP gene expression and invasion.
Multiple functions have been proposed for the ubiquitously expressed vertebrate globin cytoglobin (Cygb), including nitric oxide (NO) metabolism, lipid peroxidation/signalling, superoxide dismutase activity, reactive oxygen/nitrogen species (RONS) scavenging, regulation of blood pressure, antifibrosis, and both tumour suppressor and oncogenic effects. Since alternative splicing can expand the biological roles of a gene, we investigated whether this mechanism contributes to the functional diversity of Cygb. By mining of cDNA data and molecular analysis, we identified five alternative mRNA isoforms for the human CYGB gene (V-1 to V-5).

The likelihood of treatment success can be estimated with the tumor control probability (TCP), which requires accurate dosimetry, estimating the absorbed dose rate per unit activity to individual tumor cells. Xenograft cryosections of the prostate cancer cell line LNCaP treated with [Lu]Lu-PSMA-617 were evaluated with digital autoradiography and stained with hematoxylin and eosin.

Experiments with small molecule HDAC inhibitors (HDACi) have proven that HDACs are a vulnerability of transformed cells. We evaluated a novel hydroxamic acid-based HDACi (KH16; termed yanostat) in human pancreatic ductal adenocarcinoma (PDAC) cells, short- and long-term cultured colorectal cancer (CRC) cells, and retinal pigment epithelial cells.

Although Lu-DOTATATE is mostly well tolerated in patients, bone marrow suppression and long-term renal toxicity are still side effects that should be considered. Amino acids are often used to minimize renal radiotoxicity, however, they are associated with nausea and vomiting in patients.
View Article and Find Full Text PDFEndosomal toll-like receptors (TLRs) must be translocated from the endoplasmic reticulum (ER) to the endosome and proteolytically cleaved within the endosome before they can induce cellular signals. As ligands for these TLRs are also liberated from apoptotic or necrotic cells, this process is controlled by several mechanisms which shall ensure that there is no inadvertent activation. We have shown previously that antiphospholipid antibodies induce endosomal NADPH-oxidase (NOX) followed by the translocation of TLR7/8 to the endosome.

This study also aimed to examine the interaction between rurality and IPV revictimization in relation to victim vulnerability. The sample consisted of 695 cases of male-to-female perpetrated IPV, which had been reported to the Swedish police and subjected to a B-SAFER assessment.

While epigenetic and splicing changes have been implicated in EMT, the mechanisms governing their crosstalk remain poorly understood. Here we discovered that a C2H2 zinc finger protein, ZNF827, is strongly induced during various contexts of EMT, including in brain development and breast cancer metastasis, and is required for the molecular and phenotypic changes underlying EMT in these processes.

For alpha particles, microscopic targets must be considered to estimate dosimetric quantities that can predict the biological response. As double-strand breaks (DSB) on DNA are the main cause of cell death by ionizing radiation, cell nuclei are relevant volumes necessary to consider as targets.

Paediatr Neonatal Pain
June 2021
Preterm and sick newborn infants undergo several painful procedures during their hospital stay, potentially leading to short- and long-term negative consequences. Pain assessment should be performed regularly to provide optimal pain management. Nurses' knowledge of and attitude toward neonatal pain assessment affect how pain is assessed and managed in the clinical situation.

To understand the changes in the tumor microenvironment (TME) accompanying transition to IBC, we used multiplexed ion beam imaging by time of flight (MIBI-TOF) and a 37-plex antibody staining panel to interrogate 79 clinically annotated surgical resections using machine learning tools for cell segmentation, pixel-based clustering, and object morphometrics. Comparison of normal breast with patient-matched DCIS and IBC revealed coordinated transitions between four TME states that were delineated based on the location and function of myoepithelium, fibroblasts, and immune cells.

Conventional imaging methods have limited detection, affecting their ability to give an accurate outcome prognosis, and current therapies for metastatic prostate cancer are insufficient. This inevitably leads to patients relapsing with castration-resistant prostate cancer.
