Eighty patients with primary intraoral squamous cell carcinomas of the head and neck, with a follow-up of 4-14 years were analysed for clinical outcome in relation to immunohistochemical expression of PCNA, Ki-67, p53, bcl-2 and presence of mutations in the p53 gene. The turnout site was not associated with the different parameters calculated. PCNA and Ki-67 labelling showed median values of 56% a
While educational research and the Scholarship of Teaching and Learning (SoTL) are overlapping fields, over time there has appeared considerable friction between the two. There are claims that educational research has been tainted by SoTL’s emergence and that those engaged in SoTL lack adequate training. They maintain that those engaged in SoTL would benefit from a better understanding of educatio
The ice cover presence on the surface of a lake insulates the water body from the atmosphere. This prevents or reduces the influence of processes which depend on the exchange between the atmosphere and the water surface. This implies significant reduction or elimination of some processes taking place at the open water surface; for instance, a substantial reduction in solar energy penetrating to th
Abstract: A family with congenital dyserythropoietic anaemia type III was studied. Twenty patients and 10 of their healthy siblings were clinically examined and questioned about their medical history. Blood sampling and bone marrow aspirations were also performed. Forty‐five percent of the patients reported symptoms of anaemia and 35% regularly felt weakness, fatigue, or headache. However, the ma
Natural history museums are unique spaces for interdisciplinary research and educational innovation. Through extensive exhibits and public programming and by hosting rich communities of amateurs, students, and researchers at all stages of their careers, they can provide a place-based window to focus on integration of science and discovery, as well as a locus for community engagement. At the same t
Previous studies have indicated that a sad mood and sleep deprivation increase mind wandering, but it is unclear whether these associations reflect reduced effort in concentrating on the task at hand or diminished cognitive control. In an internet-based experiment, participants completed a sleep disturbance questionnaire followed by a complex span task and a 2-back task with thought-sampling probe
We have designed, built, and validated a (quasi)-simultaneous measurement platform called NUrF, which consists of neutron small-angle scattering, UV-visible, fluorescence, and densitometry techniques. In this contribution, we illustrate the concept and benefits of the NUrF setup combined with high-performance liquid chromatography pumps to automate the preparation and measurement of a mixture seri
BACKGROUND: Hospitalized newborn infants may require analgesia and sedation either for the management of procedural pain, during or after surgery, and other painful conditions. The benefits and harms of opioids administered at different doses and routes of administration have been reported in numerous trials and systematic reviews. The use of alpha-2-agonists such as clonidine and dexmedetomidine
We describe two novel flagellates isolated from soil, Regin rotiferus and Otto terricolus, genera et species novae, which we cultivated and characterized by light and transmission electron microscopy and by 18S rDNA sequence analysis. Both strains exhibit the key characteristic structural feature of Bicosoecida; i.e. the L-shaped cytostomal root system with an x-fiber, used for feeding. Otto terri
Hybridization in bryophytes involves a fusion of gametes produced by haploid parental gametophytes of different species. The primary hybrid is thus the short-lived diploid sporophyte, which soon undergoes meiosis prior to the formation of large amounts of haploid spores. We compared morphology of gametophytes (branch leaves) and sporophytes (capsule inclination) from sympatric populations and allo
Background: Sexual and Reproductive Health and Rights (SRHR) is a concept of human rights applied to sexuality and reproduction. Suboptimal access to SRHR services in many low-income countries results in poor health outcomes. Sustainable development goals (3.7 and 5.6) give a new impetus to the aspiration of universal access to high-quality SRHR services. Indispensable stakeholders in this process
This review presents a glossary and review of terminology used to describe the chemical and physical processes involved in soot formation and evolution and is intended to aid in communication within the field and across disciplines. There are large gaps in our understanding of soot formation and evolution and inconsistencies in the language used to describe the associated mechanisms. These inconsi
Land use contributes to environmental change, but is also influenced by such changes. Climate and atmospheric carbon dioxide (CO2) levels’ changes alter agricultural crop productivity, plant water requirements and irrigation water availability. The global food system needs to respond and adapt to these changes, for example, by altering agricultural practices, including the crop types or intensity
Purpose: Breast cancer is one of the most common cancer forms in women and it is often detected by screening. However, women with drug use disorders (DUD) are less likely to be reached by screening programs. In this study, we aimed to investigate breast cancer incidence, mortality and stage at time of diagnosis among women with DUD compared to the general female population in Sweden. Methods: We p
