The I subunit of magnesium-chelatase (CHLI) is encoded by two genes in Arabidopsis (Arabidopsis thaliana), CHLI1 and CHLI2. Conflicting results have been reported concerning the functions of the two proteins. We show here that the chli1/chli1 chli2/chli2 double knockout mutant was albino. Comparison with the pale-green phenotype of a chli1/chli1 single knockout mutant indicates that CHLI2 could...

Thiazolidinedione (TZD) is a powerful insulin sensitizer in the treatment of type 2 diabetes. It acts as a ligand to the nuclear receptor PPARγ (peroxisome proliferator-activated receptor-gamma) and induces transcription of PPARγ responsive genes. TZD controls lipid synthesis and storage in adipose tissue, liver and many other tissues through PPARγ. Derivatives of TZD, such as rosiglitazone (Av...

The exhaustible-resource monopsony problem provides a basis for understanding the dynamic relationship between resource importers and suppliers. We find that the mere presence of a substitute supply creates a time-inconsistency problem for the monopsonist. When the buyer can commit to delaying the arrival of the substitute, he obtains a substantial reduction in resource prices but not enough as...

The maxillary sinus lift technique consists in grafting a bone substitute below the sinus membrane to achieve sufficient thickness for implant stability. The golden standard as a bone substitute is the patient's autologous bone, which is not only fully biocompatible but is also able to stimulate bone regeneration through the osteoinductive factors it contains. Nonetheless, it has to be withdraw...

This thesis uses an unsensitized emulsion and two chemically sensitized emulsions to investigate the effect of oxygen and water vapor on latent-image formation and stability. At exposure times that cause little or no low-intensity reciprocity failure, vacuum treatment of an emulsion can result in photographic speeds significantly lower than those found in a humidified environment. This is presu...

Background Results of blood test are essential and often guiding for the diagnostic work. In emergency departments (EDs) a competent and rapid treatment therefore requires an efficient process for ordering blood tests, informing clinicians that samples have been taken, for communicating test results, and for physicians acknowledging having assessed results. The ED in Slagelse Sygehus has implem...

Urine discoloration occurs in the intensive care unit (ICU) due to many causes such as medications, metabolic disorders, and infections. Propofol is advocated as one of the first line sedatives in the ICU, but it is not well known to the intensivists that propofol can induce urine color change. We experienced two cases of green urine after propofol infusion. Propofol should be warranted as the ...

there are occasional reports of using the appendix to replace sections of the ureters, and to our knowledge, only a couple of them were in the left side. we used the appendix as a ureteral substitute in two cases in technically difficult parts, the upper left ureter and the first part of the right ureter. follow-ups of8 years and 6 months in right and left side cases, respectively, are impressi...

BACKGROUND Large wounds often require temporary allograft placement to optimize the wound bed and prevent infection until permanent closure is feasible. We developed and clinically tested a second-generation living human skin substitute (StrataGraft). StrataGraft provides both a dermis and a fully-stratified, biologically-functional epidermis generated from a pathogen-free, long-lived human ker...

Application of hemodialysis to dogs has been complicated by mi acute reaction consisting of hypotension, brudycardia, and respiratory depression followed by instability and a mortality rate of about 30 per cent. This reaction appeal's to be a response to homologous blood used to fill the dialyzers. Sensitization ocelli's in survivors, and accentuated reactions with marked hemolysis are noted on...
