On the Nature of Stationary and Time-Resolved Fluorescence Spectroscopy of Collagen Powder from Bovine Achilles Tendon.

This paper presents a more systematic study of steady-state and time-resolved autofluorescence spectroscopy of collagen isolated from bovine Achilles tendon. In steady-state fluorescence measurements, the excitation and emission spectra of collagen powder, recorded at different fluorescence excitation and detection wavelengths, were compared with the fluorescence excitation and emission spectra of the amino acids phenylalanine, tyrosine, and tryptophan, as well as with similar spectra for 13 autofluorescent collagen cross-links, which have been identified and described in the literature so far. In time-resolved studies, fluorescence was excited by the pulsed light of different wavelengths, and for each excitation wavelength, fluorescence decay was recorded for several detection wavelengths.

An unusual case of a tuberculous granuloma of the liver presenting thirteen years after intravesical BCG - therapy for bladder cancer.

The authors present the case of a female patient with a tumor of segment VII of the liver, which was postoperatively identified as a tuberculous granuloma. The patient was admitted for elective surgery for a liver tumor, which had been diagnosed a few months before. Computed tomography and nuclear magnetic resonance were performed, based on which focal nodular hyperplasia was suspected.

Survival after secondary cytoreductive surgery and chemotherapy compared with chemotherapy alone for first recurrence in patients with platinum-sensitive epithelial ovarian cancer and no residuals after primary treatment. A registry-based study.

Introduction: The aim of this study was to investigate whether secondary cytoreductive surgery and platinum-based chemotherapy improved survival among patients with recurrent, platinum-sensitive epithelial ovarian cancer compared with those who received platinum-based chemotherapy alone, and to identify possible predictors for selection to secondary cytoreductive surgery.

Material And Methods: We included 397 patients who had a primary diagnosis of FIGO stage I-IV epithelial ovarian cancer recorded in the Cancer Registry of Norway between 1 January 2002 and 31 December 2012, received primary surgery with no residuals followed by platinum-based chemotherapy, had first recurrence six or more months after completion of primary platinum-based chemotherapy, and received secondary treatment with either secondary cytoreductive surgery and platinum-based chemotherapy (secondary cytoreductive surgery+platinum-based chemotherapy group) or platinum-based chemotherapy alone (platinum-based chemotherapy group). Outcomes were progression-free survival to second recurrence or death and overall survival.

Activity of metalloproteinases and adiponectin in obese patients-a possible factor of incisional hernias after bariatric procedures.

Purpose: Metalloproteinases are a key component of the pathogenesis of abdominal hernias. Obesity is considered a risk factor in herniogenesis and hernia recurrence. The aim of this study was to evaluate the serum concentrations of metalloproteinase-2 (MMP-2), MMP-9, MMP-13, and adiponectin in morbidly obese and non-overweight controls.

Impact of hospital type and treatment on long-term survival among patients with FIGO Stage IIIC epithelial ovarian cancer: follow-up through two recurrences and three treatment lines in search for predictors for survival.

The purpose of this study was to investigate the impact of hospital type determined at primary treatment and find possible predictors of survival in a cohort of patients with advanced epithelial ovarian cancer (EOC) who recurred twice and received three lines of treatment during eight-year follow-up. Using the Norwegian Cancer Registry, the authors identified 174 women with FIGO Stage IIIC EOC diagnosed in 2002. First-line treatment consisted of up-front debulking surgery and chemotherapy, received in either a teaching hospital (TH, n = 84) or a non-teaching hospital (NTH, n = 90).
