3D reconstruction of histological sections: Application to mammary gland tissue

In this article, we present a novel method for the automatic 3D reconstruction of thick tissue blocks from 2D histological sections. The algorithm completes a high‐content (multiscale, multifeature) imaging system for simultaneous morphological and molecular analysis of thick tissue samples. This computer‐based system integrates image acquisition, annotation, registration, and three‐dimensional reconstruction. We present an experimental validation of this tool using both synthetic and real data. In particular, we present the 3D reconstruction of an entire mouse mammary gland and demonstrate the integration of high‐resolution molecular data. Microsc. Res.

Influence of meat quality and NaCl percentage on glutathione peroxidase activity and values for acid-reactive substances of raw and dry-cured Longissimus dorsi

Fresh and dry-cured porcine loins (Longissimus dorsi) were analysed for glutathione peroxidase (GSHPx) activity and acid reactive substances (TBARS) in order to assess the influence of meat quality and salt (NaCl) concentration on oxidative stability. The results showed lower GSHPx activity and higher TBA levels in normal meat than in PSE meat indicating a higher oxidative stress in normal meat quality. GSHPx remained active at the end of the curing process. Higher salt concentration led to lower enzyme activity and TBARS values prompted the thought of a double role of NaCl as an enzyme inhibitor and as an antioxidant molecule     

By-products of the classification of chickpea as an alternative in the production of hummus

Chickpea (Cicer arietinum L.) is a valuable source of protein, polyunsaturated fatty acids, polyphenols, dietary fibre, vitamins and complex carbohydrates, such as oligosaccharides with prebiotic activity. This study evaluates the use of by-products derived from the classification of chickpea as functional ingredients in food production. The chemical content and thermal properties of by-products (discard and split) were determined and compared to whole grains for export. Split grains had a higher protein content, lower water hydration capacity (WHC) and lower fibre. The content of oligosaccharides was lower in discard grains. For further studies, hummus was prepared with three samples, and texture and sensory analyses were performed. The results of texture and sensory analyses show no significant differences between discard and whole grains. Chemical contents of by-products show advantages for the food industry. Discard grains can be used to prepare hummus with the same technology and sensory quality as whole grains.     

Coagulation and fibrinolysis parameters in normal pregnancy and in gestational diabetes

The changes in coagulation and fibrinolysis parameters during pregnancy, delivery and 3 days after delivery were evaluated in normotensive and gestational diabetes pregnant women. Normal pregnant women (n = 60) and pregnant women with gestational diabetes (n = 15) formed the study population. Coagulation and fibrinolysis parameters were estimated using commercial tests. Antithrombin III, thrombin-antithrombin III complexes, heparin cofactor II, protein C, protein S, tissue plasminogen activator, (t-PA) D-dimer and plasminogen activator inhibitor (PAI-1 and PAI-2) activities in normal and gestational diabetes pregnancies were determined. Thrombin-antithrombin III complexes increased and coagulation inhibitors decreased in gestational diabetes. Plasminogen activator inhibitors remained unchanged and t-PA levels increased in gestational diabetes.     

Evidence for self-organized criticality in a time series of electric power system blackouts

We analyze a 15-year time series of North American electric power transmission system blackouts for evidence of self-organized criticality (SOC). The probability distribution functions of various measures of blackout size have a power tail and rescaled range analysis of the time series shows moderate long-time correlations. Moreover, the same analysis applied to a time series from a sandpile model known to be self-organized critical gives results of the same form. Thus, the blackout data seem consistent with SOC. A qualitative explanation of the complex dynamics observed in electric power system blackouts is suggested.     

Pulmonary artery thrombosis in a patient with mitral-tricuspid valve disease. Added value of peroperative transesophageal echocardiogram

The performance of peroperative transesophageal echocardiography on a 60 year old woman with mitral and tricuspid valve disease discovered a previously undiagnosed thrombus in the right pulmonary artery that completely occluded the inferior lobar branches. Following valvular surgery, a successful thromboendarterectomy was performed.
