The G1/S-phase transition is a well-toned switch in the mammalian cell cycle. Cdk2, Cdk4, and the rate-limiting tumor suppressor retinoblastoma protein (Rb) have been studied in separate animal models, but interactions between the kinases and Rb in vivo have yet to be investigated. To further dissect the regulation of the G1 to S-phase progression, we generated Cdk2-/-Cdk4-/-Rb-/- (TKO) mutant mic
A polymer electrolyte fuel cell (PEFC) produces electrical energy according to the electrochemical reactions carried out inside the cell. During the energy conversion, water molecules are also produced at the cathode side, which affects the gas diffusion layer (GDL) diffusion parameters. The generated water-drops from the reaction may give partial or total blockage of the reactant gases and also m
Modern content distribution networks face an increasing multitude of content generators. In order to reach the minimal content retrieval latency in the content distribution networks, content shall be disseminated towards consumers based on its popularity taken from the content distribution networks. This, Combined with dividing media into chunks (heterogeneous valuation of information) and contact
An autoclavable all-glass system for studying microbial dynamics at permeable surfaces is described. Standard hydrophobic or hydrophilic membranes (46-mm diameter) of various pore sizes were supported on a glass frit through which nutrient solutions were pumped by a peristaltic pump. The pump provided a precisely controlled flow at speeds of 0.5 to 500 ml of defined or natural cell exudates per h,
Human breast cancer is believed to arise in luminal progenitors within the normal breast. A subset of these are double positive (DP) for basal and luminal keratins and localizes to a putative stem cell zone within ducts. We here present a new protocol based on a combination of CD146 with CD117 and CD326 which provides an up to thirty fold enrichment of the DP cells. We show by expression profiling
Sexuality is a taboo subject in disability services, leading to insecurity for both service users and personnel about how to handle upcoming situations. In Sweden, there is also a lack of policy in this area, highlighting the need to study sexuality both as an individual and a political, and in this case also, depoliticized issue. A critical feminist policy analysis reveals that norms around disab
The isochore theory depicts the genomes of warm-blooded vertebrates as a mosaic of long genomic regions that are characterized by relatively homogeneous GC content. In the absence of genomic data, the GC content at third-codon positions of protein-coding genes (GC3) was commonly used as a proxy for the GC content of isochores. Oddly, in the postgenomic era, GC3 is still sometimes used as a proxy f
A "genome order index," defined as S=a(2)+c(2)+t(2)+g(2), where a, c, t, and g are the nucleotide frequencies of A, C, T, and G, respectively, was used to suggest that there exist genome-specific constraints on nucleotide composition. We show that the "evidence" for constraint, S<1/3, is in fact a mathematical property that is always true regardless of data. Moreover, we show that S is strictly eq
Gastric cancer (GC) is the fifth most common type of cancer worldwide with high incidences in Asia, Central, and South American countries. This patchy distribution means that GC studies are neglected by large research centers from developed countries. The need for further understanding of this complex disease, including the local importance of epidemiological factors and the rich ancestral admixtu
En ökning av andelen kollektivtrafik är en viktig del av omställningen mot lägre utsläpp av växthusgaser och mer energieffektiva transporter. I Sverige har antalet resor med kollektivtrafiken ökat med 18% mellan åren 2009 och 2015. Det finns dock en stor skillnad mellan olika regioner där ökningen varit över 20% i flera regioner medan utvecklingen av resandet har stagnerat, eller till och med mins
Behandling av patienter med alkohol- eller drogberoende är en komplex flerstegsprocess som behandlar både substansberoende och co-morbiditeter. Riskfyllda livsstilar, inklusive tobaksrökning, otillräcklig fysisk aktivitet och ohälsosam kost, som kan förvärra hälsotillståndet och själva beroendebehandlingen, är mycket vanligt bland dessa patienter. Det komplexa hälsofrämjande programmet (Very IntegTreatment of patients with alcohol or drug use disorders is a complex multistage process addressing the substance addiction and co-morbidities. The risky lifestyles, including tobacco smoking, insufficient physical activity and unhealthy diet, which can aggravate health condition as well as addiction treatment itself, are very common among these patients. The complex health promotion (Very Integra
