beta-Hexosaminidase (NAG) and percent of NAG B were studied in twenty patients following renal transplantation. Median urinary NAG for twenty reference individuals was 0.26 U/mmol creatinine and NAG B was 24%. Urinary NAG decreased rapidly from a median of 3.7 U/mmol on the third day, to 1.2 U/mmol on the 15th day after transplantation in the patients with no major complications. The percentage of

The maximal urine concentration capacity was studied in patients with acute pyelonephritis and in patients with clinically diagnosed acute cystitis. In the former group renal concentration ability was reduced in 16 of 22 patients and improved in all but two patients. Among patients with symptoms of acute cystitis 6 of 22 had a concentration capacity below 2 SD of normal values. Several of these pa

Supplemental Instruction (SI) is today a well-known academic support model to address retention and student performance in higher education. However, in studies reporting the effect of SI, the number of attendees at SI-sessions are seldom mentioned or reflected upon.This study investigates if there is a lower, optimal, and upper number of SI-attendees for SI-sessions with viable learning condition

This report is based on the contributions from SI/PASS/PAL supervisors at 63 Universities in Europe to a basic survey of 13 questions. Each institution that responded to the survey was invited to provide more detailed information about the programme including attendance statistics and examples of evaluation/impact; 45 universities provided these more detailed responses. At present, there are nine

Samverkansinlärning/Supplemental Instruction (SI) är en pedagogisk metod som syftar till att öka genomströmningen i svåra kurser. Metoden uppstod i USA vid University of Missouri Kansas City i mitten på 1970-talet och har därefter spridits till mer än 1500 högre lärosäten i ett trettiotal länder (Martin, 2008). Kort kan SI sägas vara ett studentdrivet komplement till ordinarie undervisning vid hög

The paper/presentation gives an overview of Peer-Assisted Study Schemes (SI-PASS) in Higher Education in Europe. SI-PASS is a method of improving student performance in “difficult” courses combining “how to learn” with “what to learn”. SI-PASS sessions are scheduled parallel to the regular education and are guided and facilitated by a “senior” student, the SI-PASS leader. The sessions are based on

This presentation will give an overview of a peer learning model called Supplemental Instruction - Peer Assisted Study Scheme (SI-PASS). SI-PASS was invented at the University of Missouri in Kansas City, USA in the early1970s and was then directed to Universities and for the university students. In this presentation, the focus and discussion will be on how SI-PASS can be implemented in secondary s

This presentation gives an overview of a peer learning model and academic support intervention named SI-PASS (Supplemental Instruction – Peer Assisted Study Schemes) in Higher Education in Europe. SI-PASS is a method of improving student performance in “difficult”, normally introductory, courses combining “how to learn” with “what to learn”. SI-PASS sessions are scheduled parallel to the regular e

The effect on serum lipids, lipoprotein fractions, body composition, weight gain and uremic state of including fat in intravenous nutrition was evaluated in rats with chronic uremia. Uremic rats were given high energy (1385 kJ.kg body weight-1.day-1), low nitrogen (0.6 g N.kg body weight-1.day-1) total parenteral nutrition (TPN) for 12 d with either glucose or glucose plus 30% lipids (Intralipid)

The concentrations of 25 plasma proteins were measured in 29 patients with chronic renal insufficiency. All the patients had terminal renal failure and were treated with intermittent hemodialysis, but were otherwise in good general condition at the time of investigation. The plasma levels of 8 proteins with Mr

The main goals of SI are usually to improve learning and student performance as well as increasing retention. The achievement of these goals are evaluated based on linking SI attendance with retention and student results (student performance is here often seen as a proxy for learning). However, the objectives with introducing an SI-program at a higher education institute is often so much more than

Daily variation in serum creatinine and the effect of a protein load was studied in 18 patients with renal transplants and in 10 healthy controls. Serum creatinine was analyzed both with a standard Jaffé method and with a specific HPLC technique. Following a protein meal, a 30% increase in serum creatinine levels was noted in both groups, but the rise in absolute terms was more prominent among the

The purpose of the study was to measure the urinary excretion of N‐acetyl‐beta‐glucosaminidase (U‐NAG) in patients suspected of having renovascular hypertension and to compare the enzyme excretion before and after active intervention with operation or percutaneous transluminal renal angioplasty (PTRA). Eighty‐one patients with severe, therapy‐resistant hypertension were examined with regard to ren

Plasma homocysteine in three different groups of patients with chronic renal failure (one group without dialysis, one with CAPD and one with hemodialysis) was increased compared to controls. Another group of patients with slightly reduced renal dysfunction (normal serum creatinine but reduced glomerular filtration rate) did not, however, show increase of plasma homocysteine. The clearance of homoc

We studied the occurrence of arteriovenous (A-V) shunting in three experimental rat models, namely in rejecting allograft kidney, in uni- or bilateral ureteral obstruction, and in haemorrhagic hypotension. Isografted or sham-operated rats served as controls. Radiolabelled microspheres were injected into the renal artery and the increase in the amount of radioactivity in the lungs was considered to

The nonionic low-osmolar contrast medium iohexol was used as marker of glomerular filtration rate (GFR) in 53 patients with stable renal function (group I: n = 32, group II: n = 21). All the patients had clearance values < or = 30 ml.min-1.1.73 m-2 body surface; 40 patients < 20 ml.min-1.1.73 m-2 body surface. Simultaneous determinations of renal clearance and plasma clearance, both as slope clear
