The aspartic protease cathepsin D, a poor prognostic indicator of breast cancer, is abundantly secreted as procathepsin D by human breast cancer cells and self-activates at low pH in vitro, giving rise to catalytically active cathepsin D. Due to a lower extracellular pH in tumor microenvironments compared to normal tissues, cathepsin D may cleave pathophysiological substrates contributing to cance

Objective. This study investigated whether metabolic derangement at diagnosis of diabetes mellitus affects the function of the basement membrane and the excretion of several components and whether insulin treatment can normalize this. It was designed to evaluate urinary excretion rates of transforming growth factor-1 (TGF-1), the carboxy-terminal domain of collagen IV (NC1) and albumin in children

The myeloid translocation gene 16 product MTG16 is found in multiple transcription factor-containing complexes as a regulator of gene expression implicated in development and tumorigenesis. A stable Tet-On system for doxycycline-dependent expression of MTG16 was established in B-lymphoblastoid Raji cells to unravel its molecular functions in transformed cells. A noticeable finding was that express

Objective: To evaluate the results of the expanded National Venous Screening Program (NVSP) as administered by the American Venous Forum. Methods. Eighty-three physicians across 40 states participated in screening Americans for venous disease. The NVSP instrument included demographics, venous thromboembolism (VTE) risk assessment, quality-of-life (QOL) assessment, duplex ultrasound scan for reflux

In contrast to acute lymphoblastic leukemia in children, adult cases of this disease are associated with a very poor prognosis. In order to ascertain whether the frequencies and patterns of submicroscopic changes, identifiable with single nucleotide polymorphism array analysis, differ between childhood and adult acute lymphoblastic leukemia, we performed single nucleotide polymorphism array analys

Objectives: To determine whether among middle-aged and elderly men there is evidence of international differences in the prevalence of chronic widespread pain (CWP) and whether any such differences could be explained by psychological, psychosocial factors or differences in physical health status. Methods: The European Male Ageing Study (EMAS) sampled from population registers in cities ( centres)

Experimental models implicate protease activated receptors (PARs) as important sensors of the proteolytic tumor microenvironment during breast cancer development. However, the role of the major PARs, PAR-1 and PAR-2, in human breast tumors remains to be elucidated. Here, we have investigated how PAR-1 and PAR-2 protein expression correlate with established clinicopathological variables and patient

Objective To document the frequency and causes of maternal mortality and severe (near-miss) morbidity in metropolitan La Paz, Bolivia. Design Facility-based cross-sectional study. Setting Four maternity hospitals in La Paz and El Alto, Bolivia, where free maternal health care is provided through a government-subsidised programme. Population All maternal deaths and women with near-miss morbidity. M

Forests are pivotal for biodiversity, food webs, and human economies, and as carbon sinks their climate change mitigation potential is undisputed. However, whether trees continue to efficiently accumulate biomass at an increasing rate with age, how growth trajectories respond to climate change, and vary with latitude at species range margins is under debate. Here, we combine tree-ring data with bi

Background: There is a current fashion for the use of methacrylate-containing nail cosmetics that can induce allergic contact dermatitis. European Union (EU) legislation was introduced in 2021 that had the aim of preventing its development. Objectives: To assess prevalence and exposures causing contact allergy to 2-hydroxyethyl methacrylate (HEMA) prior to and following implementation of the legis

Soil cadmium (Cd) contamination significantly threatens ecosystems and human health. Traditional geochemical investigation, although accurate, is impractical for wide-area and frequent monitoring applications. Multi-spectral satellite images combined with the homologous pollution information (HPI) and the spectral and content information of soil organic matter (SOMSCI) is an unconventional and pro

The chaperone DNAJB6b (JB6) plays important roles in increasing amyloid protein solubility and inhibiting amyloid fibril formation, a causative factor for neurodegenerative diseases like Alzheimer's and Parkinson's disease. Insights into the biophysical properties of JB6, including its structure, self-assembly and stability towards denaturation, may enhance the understanding of the physicochemical

PLATO (PLAnetary Transits and Oscillations of stars) is ESA’s M3 mission designed to detect and characterise extrasolar planets and perform asteroseismic monitoring of a large number of stars. PLATO will detect small planets (down to <2REarth) around bright stars (<11 mag), including terrestrial planets in the habitable zone of solar-like stars. With the complement of radial velocity observations

The electrochemical and electrical properties of geometrically defined electrolyte-filled microelectrodes were studied at various transelectrode current passages, using radiotracer (38Cl and 42K) and electrical techniques. Geometrically, the electrodes were defined by their tip properties that, for standard (single-barrelled, 3.0 M KCl-filled, approximately 10 M[ohm]) electrodes implied a tip open

Groundwater contamination by nitrate is a common problem in many parts of the world. The agriculturally important Shimabara district in Nagasaki, Japan, is experiencing this problem. The general source of drinking water of the study area is groundwater and consequently the nitrate contamination is a significant problem. For this reason, a groundwater investigation was performed and water samples w

Hyaluronic acid (HA) has been shown to affect angiogenesis and the function of the blood-brain barrier, and a crucial role for HA in atherosclerosis has been described. We have recently demonstrated changes in the levels of HA in cerebrospinal fluid (CSF) in patients with Alzheimer's disease (AD) with documented vascular alterations. To further investigate if the level of HA in CSF can be used as

Lymphocytes from patients with insulin-dependent diabetes have been shown to be sensitized to pancreatic tissue antigens. Mice immunized with homologous pancreatic islets have been found to develop glucose intolerance and insulitis. Since lymphocytes may be involved in diabetogenesis, we wished to determine if lymph node cells from islet-immunized mice can recognize and respond to islet cells in v

Cardiac resynchronization therapy (CRT) reduces mortality and morbidity in selected patients with heart failure (HF), but up to 1/3 of patients are nonresponders. Sum absolute QRST integral (SAI QRST) recently showed association with mechanical response on CRT. However, it is unknown whether SAI QRST is associated with all-cause mortality and HF hospitalizations in patients undergoing CRT. The stu

Introduction: The aim was to evaluate surgical treatment of newly diagnosed uterine cancer in a Swedish population. Material and methods: Data in the GynOp registry from 2008 to 2014 were analyzed. Results: In total, 3443 cases were included: 430 (12%) were robotic-assisted laparoscopic, 272 (8%) laparoscopic, and 2741 (80%) abdominal operations. There was an increasing trend in minimally invasive
