TL;DR: The hypothesis that bile can initiate acute haemorrhagic pancreatitis is supported by the results of this investigation, which created an experimental model for studying the pathogenesis of acute pancreatitis.
Abstract: Sodium taurocholate injected into the pancreatic duct system of the rat caused acute haemorrhagic pancreatitis. The pancreatic lesions were immediate and characterized by interstitial oedema, extensive necrotic changes of the acinar cells, and haemorrhages during the first 24 h after the injection. In animals surviving 72 h there were marked acinar atrophy and pancreatic fibrosis. The mortality increased according to the amount of sodium taurocholate injected. Except for necrosis of occasional liver cells, other organs examined were histologically normal. This investigation created an experimental model for studying the pathogenesis of acute pancreatitis. The results support the hypothesis that bile can initiate acute haemorrhagic pancreatitis.

TL;DR: The lower BMD in type 1 versus type 2 diabetic patients and control subjects probably results from more rapid bone loss after the onset of type 1 diabetes.
Abstract: OBJECTIVE: To assess the effect of type 1 and type 2 diabetes and insulin treatment on bone mineral density (BMD) in middle-aged and elderly men and women. RESEARCH DESIGN AND METHODS: We measured BMD and evaluated known determinants of osteoporosis in 56 type 1 and 68 type 2 diabetic patients and 498 nondiabetic community control subjects. All patients, aged 52-72 years, developed diabetes after the age of 30 years (i.e., after achievement of peak bone mass) and were treated with insulin. BMD was measured at the proximal femur with dual-energy X-ray absorptiometry. RESULTS: Among both sexes, BMD values were significantly lower in type 1 diabetic patients than in type 2 diabetic patients or the control subjects. When adjusted for age and BMI, the differences between type 1 diabetic patients and control subjects remained essentially unchanged in both sexes, whereas the differences between type 1 and type 2 diabetic subjects were significant only in men. After further adjustments for confounding factors, the average BMD values were still lower in type 1 diabetic subjects than in type 2 diabetic subjects although with lesser significance. Past low-energy fractures were more common in type 1 diabetic women than in type 2 diabetic women. CONCLUSIONS: The lower BMD in type 1 versus type 2 diabetic patients and control subjects probably results from more rapid bone loss after the onset of type 1 diabetes. This cannot be explained by insulin treatment, which was prescribed for both types of patients. Because the causes of low BMD in type 1 diabetes are unknown, these patients should be evaluated for the risk of osteoporosis and related fractures and offered appropriate preventive measures.

TL;DR: In this paper, the authors used the temperature-gradient correlations induced by lensing to reconstruct a (noisy) map of the CMB lensing potential, which provides an integrated measure of the mass distribution back to the last-scattering surface.
Abstract: On the arcminute angular scales probed by Planck, the cosmic microwave background (CMB) anisotropies are gently perturbed by gravitational lensing. Here we present a detailed study of this e_ect, detecting lensing independently in the 100, 143, and 217 GHz frequency bands with an overall significance of greater than 25_.We use the temperature-gradient correlations induced by lensing to reconstruct a (noisy) map of the CMB lensing potential, which provides an integrated measure of the mass distribution back to the CMB last-scattering surface. Our lensing potential map is significantly correlated with other tracers of mass, a fact which we demonstrate using several representative tracers of large-scale structure. We estimate the power spectrum of the lensing potential, finding generally good agreement with expectations from the best-fitting _CDM model for the Planck temperature power spectrum, showing that this measurement at z = 1100 correctly predicts the properties of the lower-redshift, latertime structures which source the lensing potential. When combined with the temperature power spectrum, our measurement provides degeneracy breaking power for parameter constraints; it improves CMB-alone constraints on curvature by a factor of two and also partly breaks the degeneracy between the amplitude of the primordial perturbation power spectrum and the optical depth to reionization, allowing a measurement of the optical depth to reionization which is independent of large-scale polarization data. Discarding scale information, our measurement corresponds to a 4% constraint on the amplitude of the lensing potential power spectrum, or a 2% constraint on the root-mean-squared amplitude of matter fluctuations at z _ 2.

TL;DR: In this article, a new framework for analysing attitude and changes in attitude is proposed, and a case study of a lower secondary school student with negative attitude towards mathematics is presented.
Abstract: This article suggests a new framework for analysing attitude and changes in attitude. After reviewing relevant findings in the field of psychology of emotions, the author will provide a new conceptualisation for attitude. Four different evaluative processes are identified as aspects of attitude: emotions aroused in the situation, emotions associated with the stimuli, expected consequences, and relating the situation to personal values. The usefulness of this analytical framework will be illustrated with an exemplary case study. An ethnographic case study of Rita, a lower secondary school student, will be analysed. The case study will describe her negative attitude towards mathematics, and then examine how negative emotions developed during problem solving situations. Within half a year her attitude towards mathematics changed dramatically to more positive.
