Shifts in microbial stoichiometry upon nutrient addition do not capture growth-limiting nutrients for soil microorganisms in two subtropical soils

Microbial stoichiometry has become a key aspect in ecological research as shifts in microbial C:N, C:P and N:P ratios upon nutrient addition are presumed to give insight into relative nutrient limitations for soil microorganisms–with far-reaching implications for biogeochemical processes. However, this expectation has never been tested against direct methods of microbial growth responses to nutrie

Degranulation patterns of eosinophil granulocytes as determinants of eosinophil driven disease

BACKGROUND: Degranulation of eosinophils in target tissues is considered a key pathogenic event in major chronic eosinophilic diseases. However, because of a lack of appropriate methods, little is known about degranulation of eosinophils in common eosinophilic diseases. METHODS: Using transmission electron microscopic (TEM) analysis, a novel approach has been devised and validated to quantify eosi

Hypoxia-Related Processes in the Baltic Sea

Hypoxia, a growing worldwide problem, has been intermittently present in the modern Baltic Sea since its formation ca. 8000 cal. yr BP. However, both the spatial extent and intensity of hypoxia have increased with anthropogenic eutrophication due to nutrient inputs. Physical processes, which control stratification and the renewal of oxygen in bottom waters, are important constraints on the formati

Midwifery students’ experiences of learning through the use of written reflections – An interview study

In an effort to strengthen midwifery students’ learning process, written reflections during the students’ clinical practice at birth units have been applied. The aim of this study was to examine how students of midwifery experienced the writing of daily reflections on their practice at birthing units. An interview study was carried out using an inductive method with descriptive design. During 2013

Degree of Breathiness in a Synthesized Voice Signal as it Differentiates Masculine versus Feminine Voices

Introduction: Most studies determining speakers’ perceived gender as binarily female or male are reliant on F0 perception, although other vocal parameters may also contribute to the perception of gender. The current study focused on the impact of breathiness on the perception of speakers’ gender as a biological variable (feminine or masculine). Methods: n = 31 normal hearing, native English speake

A Disentangled VAE-BiLSTM Model for Heart Rate Anomaly Detection

Cardiovascular diseases (CVDs) remain a leading cause of death globally. According to the American Heart Association, approximately 19.1 million deaths were attributed to CVDs in 2020, in particular, ischemic heart disease and stroke. Several known risk factors for CVDs include smoking, alcohol consumption, lack of regular physical activity, and diabetes. The last decade has been characterized by

Differential responses to con- and allospecific visual cues in juvenile ravens (Corvus corax) : the ontogeny of gaze following and social predictions

Gaze following refers to the ability to co-orient with others’ gaze directions. Ontogenetic studies on gaze following in animals have predominantly used human experimenters as demonstrators. It is, however, likely that developing animals are initially more attuned to individuals from their own species, which might result in differences in the ontogenetic onset of gaze following with human and cons

COSCA (Core Outcome Set for Cardiac Arrest) in Adults : An Advisory Statement From the International Liaison Committee on Resuscitation

Cardiac arrest effectiveness trials have traditionally reported outcomes that focus on survival. A lack of consistency in outcome reporting between trials limits the opportunities to pool results for meta-analysis. The COSCA initiative (Core Outcome Set for Cardiac Arrest), a partnership between patients, their partners, clinicians, research scientists, and the International Liaison Committee on R

Fragmentation in disaster risk management systems: A barrier for integrated planning

The need to integrate climate change adaptation (CCA) considerations into disaster risk management (DRM) systems is widely recognised. However, successful integration, and thus the implementation of integrated planning measures, is difficult in practice. To understand and reduce the problems encountered, it is important to investigate systemic challenges. These challenges are rooted in the interac

Statins : a role in breast cancer therapy?

Statin drugs have been used for more than two decades to treat hypercholesterolemia and as cardio-preventive drugs, resulting in a marked decrease in cardiovascular morbidity and mortality worldwide. Statins halt hepatic cholesterol biosynthesis by inhibiting the rate-limiting enzyme in the mevalonate pathway, hydroxymethylglutaryl-coenzyme A reductase (HMGCR). The mevalonate pathway regulates a h

Factors and conditions that have an impact in relation to a successful implementation and maintenance of individual care plan.

Background: The gap between what is stated in legislation about written individualized nursing care plans (ICP) and how they are used in practice is still too wide.Aim: To explore attitudes and experiences among nurses and managers in order to capture which factors and conditions impact on the successful implementation of individual care plans within hospital care, as well as the strategies that w

Postischemic blockade of AMPA but not NMDA receptors mitigates neuronal damage in the rat brain following transient severe cerebral ischemia

Glutamatergic transmission is an important factor in the development of neuronal death following transient cerebral ischemia. In this investigation the effects of N-methyl-D-aspartate (NMDA) and non-NMDA receptor antagonists on neuronal damage were studied in rats exposed to 10 min of transient cerebral ischemia induced by bilateral common carotid occlusion combined with hypotension. The animals w

Tradeoffs and synergies in wetland multifunctionality : A scaling issue

Wetland area in agricultural landscapes has been heavily reduced to gain land for crop production, but in recent years there is increased societal recognition of the negative consequences from wetland loss on nutrient retention, biodiversity and a range of other benefits to humans. The current trend is therefore to re-establish wetlands, often with an aim to achieve the simultaneous delivery of mu

Prevention of posttraumatic osteoarthritis at the time of injury : Where are we now, and where are we going?

This overview of progress made in preventing post-traumatic osteoarthritis (PTOA) was delivered in a workshop at the Orthopaedics Research Society Annual Conference in 2019. As joint trauma is a major risk factor for OA, defining the molecular changes within the joint at the time of injury may enable the targeting of biological processes to prevent later disease. Animal models have been used to te

Combustion sensitivity to the nozzle hole size in an active pre-chamber ultra-lean heavy-duty natural gas engine

Active pre-chamber configurations are considered a valuable solution for improving the operation of the internal combustion engine, in the view to overcome the many challenges it has been made to face. Combining this technology with the use of natural gas, a fuel that has increasing availability and interest in the market share, it is possible to burn ultra-lean mixtures (with air-to-fuel ratios,

Composition and Seasonality of Membrane Transporters in Marine Picoplankton

In this study, we examined transporter genes in metagenomic and metatranscriptomic data from a time-series survey in the temperate marine environment of the Baltic Sea. We analyzed the abundance and taxonomic distribution of transporters in the 3μm–0.2μm size fraction comprising prokaryotes and some picoeukaryotes. The presence of specific transporter traits was shown to be guiding the succession

Gene amplification in neoplasia : A cytogenetic survey of 80 131 cases

Gene amplification is a crucial process in cancer development, leading to the overexpression of oncogenes. It manifests cytogenetically as extrachromosomal double minutes (dmin), homogeneously staining regions (hsr), or ring chromosomes (r). This study investigates the prevalence and distribution of these amplification markers in a survey of 80 131 neoplasms spanning hematologic disorders, and ben
