Background. To evaluate the relationship between age and poor ovarian response to pregnancy and cancellation rate after IVF stimulation. Methods. Poor ovarian response was defined as <= 5 follicles at ovum pick up (OPU). Out of 1,706 consecutive OPUs performed during 2003/2004, 290 poor responders were identified. This cohort of poor responders was divided into two groups, 'older' and 'younger', w
The evolution of radiation-induced carbon-related defects in low temperature irradiated oxygen containing silicon has been studied by means of Fourier transform infrared absorption spectroscopy (FTIR) and deep level transient spectroscopy (DLTS). FTIR measurements have shown that annealing of interstitial carbon atom C-i, occurring in the temperature interval 260-300 K, results in a gradual appear
Studies published between 2001 and 2005 that utilise cryogenic transmission electron microscopy as a tool for investigating solutions containing DNA with or without amphiphiles present are reviewed. DNA or oligonucleotides form complexes with amphiphilic molecules such as lipids, so-called lipoplexes, and the structures and morphologies are excellent objects to study by cryogenic transmission elec

We consider a nontrivial symmetric periodic gravity wave on a current with nondecreasing vorticity. It is shown that if the surface profile is monotone between trough and crest, it is in fact strictly monotone. The result is valid for both finite and infinite depth.
OBJECTIVES: To evaluate the influence of residual beta-cell function on glucagon secretion and glucose counter-regulation following hypoglycaemia in type 1 diabetes. DESIGN AND SUBJECTS: The hormonal counter-regulatory responses to standardized insulin-induced hypoglycaemia were investigated, 18 patients with type 1 diabetes of long duration and 12 healthy subjects were investigated. Nine of the d
The article is devoted to investigation of the classes of functions belonging to the gaps between classes Pn+1 (I) and P, (I) of matrix monotone functions for full matrix algebras of successive dimensions. In this paper we address the problem of characterizing polynomials belonging to the gaps P-n(I) Pn+1 (I) for bounded intervals L We show that solution of this problem is closely linked to soluti
The present contribution focuses on the mathematical techniques used to solve steady state metabolic models for the case of an overdetermined system. Even when parts of the system are underdetermined it is possible to solve the model partially and obtain statistically meaningful results. This is illustrated with data gathered from a set of E. coli W3110.shik1 phosphate- or carbon-limited continuou
A simple, efficient, and flexible procedure for the synthesis of chiral, amphiphilic, and water-soluble macrocycles is reported. Acylation of p-xylylenediamine with N-Fmoc-protected glycine, -aspartic acid, -glutamic acid, and -arginine, followed by removal of Fmoc-groups, gave amino acid:p-xylylene conjugate diamines, which were converted to ten macrocycles via stepwise urea formation using p-nit
A survey at all six medical faculties in Sweden in the spring 2004 showed that basic medical schooling (Medical School) only included an average of 59 full hours of geriatrics, with a fivefold variation between universities (19 to 106 hours). This is despite the fact that the need for geriatric skills in the health care sector is steadily increasing. A test of general knowledge in geriatrics just
This work proposes methodologies using a model-based approach to gain knowledge on and assist the development of an ion-exchange step in a protein purification process; the separation of IgG from a mixture containing IgG, insulin and transferrin. This approach is suitable for capture and intermediate steps in a process. Both methods involve four consecutive steps. Firstly, the retention of the dif
Accurate measurements of solute concentration are needed to conduct studies of solute transport process in unsaturated soil. In this paper we present a method of obtaining accurate measurements in and space using dye infiltration and image analysis. The soil color was related to the dye concentration in the soil (C-s) using 74 small calibration samples. The overall root mean square error (RMSE) 0.
Cysteine proteinases, especially cathepsin K, play an important role in osteoclastic degradation of bone matrix proteins and the process can, consequently, be significantly inhibited by cysteine proteinase inhibitors. We have recently reported that cystatin C and other cysteine proteinase inhibitors also reduce osteoclast formation. However, it is not known which cysteine proteinase(s) are involve
We compared the differences between spring and autumn in migration speed, fuelling rates and fuel loads of migrating Red Knots Calidris canutus. As a basis we used ringing data from Ottenby Bird Observatory, southeastern Sweden, collected 1948–2003, with morphometrical data from 1990–2003. Numbers ringed varied between 0 and 301 per year (average 56). Morphometrics, recoveries and recaptures of ri
Popular Abstract in Swedish Avhandlingen består av tre artiklar som med en teoretisk utgångspunkt valutamarknader och valutaprissättning. Framförallt undersöks vilken roll förväntningarna har vid prissättningen på valutor. Normalt tänker man på priset på en valuta som växelkursen, det vill säga ett pris mätt i termer av en annan valuta. Men vad är det egentligen som bestämmer den aktuella och den The thesis consists of three essays on currency markets, equilibrium and expectations. The first essay examines currency markets in the setting of a temporary equilibrium model with two currencies and two central banks, where consumers have one-point expectations. Assuming that both central banks use floating exchange rate policies it is shown that if consumers have common expectations the curren
