Pseudoangiomatous stromal hyperplasia (PASH) is a rare benign breast entity scarcely reported in the medical literature. Its pathogenesis, etiology, and optimal treatment are still unknown. PASH tumors have a broad spectrum of clinical presentations and might be mistaken for malignancies. The authors present six patients diagnosed with PASH. 相似文献

This study presents the conversion of bovine horn powder (BHP) as an available and low-cost waste material to a value-added highly recyclable catalyst. This green catalyst was prepared through the immobilization of BHP, as a natural keratin resource, on the magnetic Fe3O4 nanoparticles. The successful preparation of the catalyst was fully investigated using Fourier transform infrared, X-ray diffraction, and energy-dispersive X-ray spectroscopies as well as field emission scanning electron microscopy, vibrating sample magnetometry, and thermogravimetry. The catalytic efficiency of the prepared magnetic organocatalyst was evaluated in the synthesis of a large series of amide derivatives through the solvent-free transamidation reaction of different amides and amines with yields of 75–96%.The conversion of bovine horn powder as an available and low-cost waste material to a value-added recyclable organocatalyst for transamidation reaction. 相似文献

ObjectiveAdipokines are signaling and mediator proteins secreted from adipose tissue. A novel adipokine, visfatin, was reported as a protein which was mainly expressed in visceral adipose tissue. Controversial results have been shown regarding the changes of adipokines following weight reduction. So we investigated the effects of weight reduction on serum concentrations of adiponectin and visfatin in morbidly obese subjects.Methods35 severely obese patients (26 females and 9 males), aged 15-58 years, were studied. Anthropometric parameters and biochemical parameters as well as adiponectin and visfatin were analyzed before and 6 weeks after weight reduction.ResultsAnthropometric indices decreased significantly. Blood levels of low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, and triglyceride were reduced significantly. The reduction of visfatin and the elevation of adiponectin were significant as well. However, other parameters like fasting glucose and insulin did not change. Moreover, we could not find any significant correlation between the change of serum visfatin and that of adiponectin. Conclusions: 6-week weight reduction after bariatric surgery resulted in decreased serum visfatin and increased adiponectin levels. However, we cannot find any significant correlation between changes of adiponectin, visfatin, BMI, waist circumference, and insulin resistance. Further studies with different design are suggested to clarify these associations.Key Words: Adiponectin, Visfatin, Morbid obesity, Bariatric surgery, Weight loss 相似文献

Purpose
The present study was designed to compare novel risk factors for cardiovascular diseases (CVD) between hemodialysis (HD) patients with or without protein-energy wasting (PEW) for determining novel risk factors for CVD in HD patients with PEW.Methods
In this cross-sectional study, 291 HD patients were randomly selected from among 2,302 adult HD patients in Tehran hemodialysis centers. The presence of PEW in HD patients was determined by subjective global assessment. In addition, 4 mL blood was obtained before dialysis and analyzed for serum concentrations of novel risk factors for CVD, including C-reactive protein (CRP), soluble intercellular adhesion molecule type 1 (sICAM-1), soluble vascular cell adhesion molecule type 1 (sVCAM-1), sE-selectin, malondialdehyde (MDA), nitric oxide (NO), endothelin-1 and lipoprotein (a) [Lp (a)].Results
Serum CRP and sICAM-1 were significantly higher in HD patients with PEW as compared to those without PEW (P < 0.01), whereas there were no significant differences in serum sVCAM-1, sE-selectin, MDA, NO, endothelin-1 and Lp (a) between the two groups. Serum CRP and sICAM-1 were significantly higher in HD patients with PEW type IIa and IIb than in those with PEW type I (P < 0.01).Conclusion
The present study indicates that serum CRP and sICAM-1, as two CVD risk factors, increase in HD patients with PEW as compared to those without PEW and these increases occur in HD patients with PEW type IIa and IIb who have inflammation. 相似文献10.
