Hydric properties evolution during drying differs from one product to another and has been the subject of various studies due to its crucial importance in modeling the drying process. The variation of these parameters in the solid matrix and in time during the drying of Spirulina platensis has not known an advanced understanding. The objective of this study was to evaluate the evolution of the water content profile, the mass flow, the concentration gradient and the diffusion coefficient during the drying of Spirulina platensis taking into account the shrinkage. Modeling and experimental analysis (at 50°C and HR = 6%) by the cutting method a cylinder 20 mm in diameter and 40 mm thick were carried. The water content profiles of two different products grown in semi-industrial farms from Burkina Faso and France with initial water contents respectively of the range from 2.73 kgw/kgdb and 3.12 kgw/kgdb were determined. These profiles have been adjusted by a polynomial function. Identical water behavior is observed regardless of the origin of the samples. Water distribution is heterogeneous. Mass flow and concentration gradient are greater at the edge than inside the product. The water transport coefficient, ranging from 1.70 × 10?10 to 94 × 10?10 m2/s, is determined from a linear approach.

Background: The mobilization of hematopoietic progenitor cells from bone marrow has been proposed to play a role in cardiac regeneration after myocardial infarction(MI). Accordingly, an increase in CD34 positive cells(CD34+) has been observed in the peripheral blood of patients after acute myocardial infarction. Here, we evaluated the influence of an acute percutaneous coronary intervention(PCI) of the occluded artery on the mobilization of CD34+in acute MI. Methods: CD34 positive cells were quantified by flow cytometry(FACS analysis) and expressed as number per million white blood cells. Peripheral blood was obtained and analyzed at day 5 after the onset of symptoms from patients with acute MI without early PCI(n=11, age 63±5 years), acute MI with rapid PCI(n=7, age 63±3), patients with pneumonia(n=5, age 51±6), patients without angiographical signs of coronary artery disease(control, n=5, age 66±8) and young healthy volunteers(n=11, age 28±1). Results: Patients with MI but without PCI had a higher CD34+count at day 5(312±48 per 106 leukocytes) than control(156±40, P=0.03) and MI with PCI(173±31, P=0.03). No increase in CD34+was observed in patients who underwent PCI vs. control. Patients with pneumonia had higher CD34+(350±44) than patients with MI with PCI(P=0.01) and control(P=0.01). Healthy individuals who were much younger than all other groups(28±1 years, Pjor factor that influences the mobilization of CD34+cells and the regenerative capacity of the heart.

Purpose: The difference in central corneal thickness among subgroups of glaucoma patients, as well as its influence on Goldmann applanation tonometry, has beenwell documented in several clinical trials. In the present study, possible similarities and differences between central corneal thickness and corneal thickness of paracentral quadrants in patients with normal tension glaucoma (NTG) and ocular hypertension (OHT) were investigated. Methods: Central and paracentral corneal thickness was measured by optical slit scan pachymetry (Orbscan II). Fourteen patients (28 eyes) with NTG and 11 patients (22 eyes) with OHT were included in this study. t-Test was performed for statistical analysis. To evaluate overall corneal topography, the mean and SD values of the differences between the central corneal thickness and each peripheral quadrant were analysed. Results: The following data was obtained (μ m): (central, upper, temporal, nasal, inferior paracentral quadrant): OHT group 617- 695- 663- 687- 660. NTG group 568- 629- 593- 612- 616. Corneal thickness of all four paracentral quadrants differed significantly between the OHT and NTG groups. There was a more heterogeneous intraindividual pattern of overall corneal topography in the OHT group, and a more heterogeneous pattern of corneal topography among the individuals of the NTGgroup (interindividual heterogeneity). Conclusions: A comparison of central corneal thickness and paracentral corneal thickness revealed clinically relevant differences between the OHT and NTG groups. The presented data underlines the importance of correlating the site of applanation with the corresponding corneal thickness, especially in OHT patients. It further substantiates the necessity to obtain individual pachymetric data for each NTG patient.

Background: Breast cancer can metastasize to the esophagus and the mediastinum . EUS-guided FNA (EUS-FNA) is being used increasingly as a less invasive alter native to mediastinoscopy for procuring a tissue diagnosis of mediastinal diseas e and may be useful for the diagnosis of breast cancer metastatic to the esophagus and the mediastinum. Methods: Twelve women(age range 54-82 years) with a history of breast cancer presented with dy sphagia or other symptoms between 1 and 15 years after initial diagnosis and tre atment. CT and endoscopy with biopsies suggested a mediastinal mass or lymphaden opathy with extrinsic esophageal compression but failed to provide a tissue diag nosis. EUS-FNA was performed for ***: Cytologic evaluation of spe cimens obtained by EUSFNA confirmed breast cancer metastases in 11 of 12 patient s(91%). Recurrent disease was found in intramural masses and periesophageal lym ph nodes. No complication resulted from any EUS-FNA procedure. Conclusions: EUS -FNA is safe and effective for the diagnosis of breast cancer metastases to the esophagus and the mediastinum. EUS-FNA may be useful as a first-line method o f evaluation when breast cancer metastasis to the esophagus and the mediastinum is suspected.

Objective. To analyze the predictive effect on obstetrical outcome in women with prenatal exposure to diethylstilbestrol (DES) of previous obstetrical history or the specific risk of DES exposure. Patients and methods. We included all in utero DES- exposed women (454 women) followed and delivered at one maternity unit in Paris and compared them with two control women matched for age, parity, number of late fetal losses, number of previous preterm births, number of singleton or twin fetuses, and follow- up, who were managed by the same team or referred for pregnancy complication. Results. DES women had a higher rate of preterm birth (19.2% ) than matched controls (10.5% ), even when considering women with a previous preterm birth or twin pregnancy. The rate of fetal or neonatal deaths were lower in DES- exposed women than in controls. DES women showed a higher rate of severe post partum bleeding (2.8% ) than matched controls (1.5% ) or the global population of women delivered in this maternity unit. Conclusion. A history of prenatal exposure to DESis a major predictor of preterm birth for primiparous women and for those with an adverse obstetrical history.

肉瘤在乳房恶性肿瘤中的发生率仅占0.5%～3%,脂肪肉瘤则仅占乳腺肉瘤的0.3%,因而与四肢及腹膜后的肉瘤相比仅属罕见。一些脂肪肉瘤是在乳腺纤维腺瘤的基础上恶变而成,或由叶状囊性肉瘤转化而来,其余则为乳腺的原发性肉瘤。本瘤首先由 Virchow 于1857年描述,第一例由 Neumann于1862年报道,迄今共报道近百例。本文1例为26岁患者,原患粘液样内瘤,组织学上未分化并继之以双侧乳房癌。
