Cytosolic NADPH can be directly oxidized by a calcium-dependent NADPH dehydrogenase, NDB1, present in the plant mitochondrial electron transport chain. However, little is known regarding the impact of modified cytosolic NADPH reduction levels on growth and metabolism. Nicotiana sylvestris plants overexpressing potato NDB1 displayed early bolting whereas sense-suppression of the same gene led to de
A series of CCK2 receptor ligands were analysed with respect to their interaction with binding sites in the membranes of COS-7 cells and SK-N-MC cells transiently expressing the human CCK2 receptor (short isoform). The ligands were YF476, YM022, AG041R, L-740,093, JB93182, PD134308, and PD136450. Their binding was analysed by radioligand competition using [H-3]L-365,260 as the labelled ligand. Sat
Background: Human breast tissue undergoes phases of proliferation, differentiation and regression regulated by changes of the levels of circulating sex hormones during the menstrual cycle or aging. Ovarian hormones also likely play a key role in the etiology and biology of breast cancer. Reports concerning the proliferative effects of steroid hormones on the normal epithelium of human breast have
Popular Abstract in Swedish Blodkärlens insida bekläds av ett lager platta celler, s.k. endotelceller. Syrgas, näring och hormonella signaler måste passera dessa celler för att nå ut till kroppens olika vävnadsceller. På endotelcellernas yta finns normalt strukturer som förhindrar att blodceller (vita blodkroppar och blodplättar) fastnar och därigenom underlättas blodflödet. Endotelcellerna bildarThe vascular endothelium is an important regulatory organ in circulatory physiology and plays a central role in the response to acute inflammation and ischemia/reperfusion. Activation and dysfunction of the pulmonary vascular endothelium are closely related to clinical findings of pulmonary dysfunction. The endothelial-derived relaxing factor, nitric oxide (NO), is a gas, which can be administered
Chronic hyperglycemia leads to pancreatic beta-cell dysfunction characterized by diminished glucose-stimulated insulin secretion (GSIS), but the precise cellular processes involved are largely unknown. Here we show that pancreatic beta-cells chronically exposed to a high glucose level displayed substantially increased amounts of stress fibers compared with beta-cells cultured at a low glucose leve
By growth of Si on substrates that have been pre-patterned by electron-beam induced carbon nano-growth masks, nano-holes form at the Si surface. We have grown self-assembled Ge quantum dots in these holes by ultra high vacuum chemical vapour phase deposition (UHV-CVD). We usually find four dots in each hole. By varying the amount of deposited Ge, we can obtain either four dome-shaped or four pyram
With shrinking technologies and higher clock rates comes the possibility to transform multi chip implementations to a single System on Chip (SoC). Implementing clock distribution and limiting the power consumption becomes increasingly troublesome with increased clock rate and chip area. Therefore, designing large Systems on Chip makes it necessary to search for new implementation methods. In this
Background: Neutralizing antibodies provide markers for vaccine-induced protective immunity in many viral infections. By analogy, HIV-1 neutralizing antibodies induced by immunization may well predict vaccine effectiveness. Assessment of neutralizing antibodies is therefore of primary importance, but is hampered by the fact that we do not know which assay(s) can provide measures of protective immu
Laser-based diagnostic techniques have been utilized to analyse a variety of processes, offering valuable insights on temperature and species concentrations with non-intrusive measurements, while maintaining high temporal and spatial resolution. With the advent of technology and the introduction of lasers with high peak power, such as femto-second (fs) lasers, the full potential of these diagnosti
This paper presents a participatory, qualitative focus group study with 13 young carers -- young people between 13 to 18 years old who take care of a parent due to either a chronic illness, mental health problem, or other condition connected with a need for care in Wales and England. We identify and assert young carers as an important, thus far unconsidered, user group in Human-Robot Interaction
Organ function depends on the three-dimensional integrity of the extracellular matrix (ECM). The structure resulting from the location and association of ECM components is a central regulator of cell behavior, but a dearth of matrix-specific analysis keeps it unresolved. Here, we deploy a high-resolution, 3D ECM mapping method and design a machine-learning powered pipeline to detect and characteri
During evolution the human brain has increased drastically in size compared to that of other primates. However, little is known about primate brain development as it is difficult to study human and primate brains in the laboratory due to the scarcity of tissues. Yet, it is essential to study primate brains and understand the molecular features leading to the human brain’s unique cognitive function
