The limiting factor for quantitative histochemistry employing freeze-dried tissue sections is the ability to identify morphologic structures. Satisfactory staining of freeze-dried tissue specimens intended for further microanalysis was achieved by using isopentane solutions of free dye bases. The practical details of this rapid histologic control are outlined and its usefulness is illustrated by m

Previous studies have revealed the existence of two separate phases in the glucose-stimulated insulin release. Exposure of microdissected mouse islets to mannoheptulose or epinephrine effectively inhibited both the initial transient release and the second persistent phase of insulin secretion. These results suggest that metabolism of glucose is a prerequisite for both phases of insulin release. Th

The pancreatic islets in obese-hyperglycemic mice display a normal response of insulin secretion when stimulated with glucose in vitro. This indicates that the impaired glucose metabolism is due to extra-pancreatic factors rather than to deficient β-cell function. In fact, the pancreas of these mice is a useful source from which to isolate large numbers of mammalian β-cells suitable for studies of

The release of insulin in vitro from isolated mouse islets was significantly inhibited in the presence of an islet protein extract equivalent to more than 100 times the normal serum level of insulin. The nature of the inhibitory islet substance remains unclear. The possibility that the blood circulation through the islets may be important for the local regulation of insulin release by reducing hig

Second mitochondria-derived activator of caspase (SMAC) mimetics (SMs) are selective antagonists of the inhibitor of apoptosis proteins (IAPs), which activate noncanonical NF-B signaling and promote tumor cell death. Through gene expression analysis, we found that treatment of CD4+ T cells with SMs during T helper 17 (TH17) cell differentiation disrupted the balance between two antagonistic transc

The Swedish Association for Child and Adolescent Psychiatry conducted a survey among their specialty trainees in 2018. Of the 48% response rate, around 48% admitted hesitancy to continue in their chosen specialty. A further 12% planned to depart from their field after completion of training. Factors associated with discontinuation in training were the perception of ineffective psychotherapeutic tr

We derive ab initio optical potentials from self-consistent Green's function theory and compute the elastic scattering of neutrons off oxygen and calcium isotopes. The comparison with scattering data is satisfactory at low scattering energies. The method is benchmarked against the no-core shell model with continuum calculations, showing that virtual excitations of the target are crucial to predict

Background: The current study aimed at exploring adolescents' experiences of online sexual contacts leading to online sexual abuse by a perpetrator whom the victim had first met online. Associations with socio demographic background, experience of abuse, relation to parents, health and risk behaviors were studied. Methods: The participants were a representative national sample of 5175 students in

Drought in Australia has widespread impacts on agriculture and ecosystems. Satellite-based Fraction of Absorbed Photosynthetically Active Radiation (FAPAR) has great potential to monitor and assess drought impacts on vegetation greenness and health. Various FAPAR products based on satellite observations have been generated and made available to the public. However, differences remain among these d

Purpose: In Sweden, the care of older people and people with disabilities is increasingly carried out by informal carers, often family members, who are unpaid and outside a professional or formal framework. While there is an increasing awareness of the role of carers within service systems and their own needs for support, their involvement in research is underexplored. The purpose of this paper is

Background: Alzheimer's disease (AD) is characterized by misfolding and aggregation of naturally occurring beta-amyloid peptides (Aβ). These aggregates are thought to be pathogenic to neurons, although the conformation of the pathogenic Aβ species remains unclear. Biochemical extraction methods and different microscopy techniques (TEM, confocal) can be used to identify pathogenic Aβ species in the

This study examined the differences in health spending within the World Health Organization (WHO) Europe region by comparing the EU15, the EU post-2004, CIS, EU Candidate and CARINFONET countries. The WHO European Region (53 countries) has been divided into the following sub-groups: EU15, EU post-2004, CIS, EU Candidate countries and CARINFONET countries. The study period, based on the availabilit
