We demonstrated a simple one-pot synthesis approach for the controlled composition of homogeneous FePt and phase-controlled heterostructured FePt/Fe3O4 nanocubes (NCs) utilizing 1,2-hexadecanediol and 1-octadecene as the reducing agents, respectively. When the Fe : Pt precursor ratio was varied from 1 : 1 to 4 : 1 and 1,2-hexadecanediol was utilized as the reducing agent, homogeneous FePt NCs were formed, whereas the heterostructures of FePt/Fe3O4 NCs were obtained when utilizing 1-octadecene as the reducing agent at Fe : Pt ratio of 4 : 1. The initial domination of nucleation of Pt-rich species and the subsequent deposition of Fe atoms leads to the formation of homogeneous FePt NCs. Heterostructured FePt/Fe3O4 NCs were obtained by the initial FePt seed formation, which was then followed by the heterogeneous growth of Fe3O4. The heterostructured FePt/Fe3O4 NCs exhibited two phases, i.e., FePt phase with a (111) facet of the fcc and Fe3O4 phase with an inverse cubic spinel structure. Moreover, both the FePt and the FePt/Fe3O4 NCs demonstrated almost negligible coercivity, which confirmed a typical superparamagnetic behavior. Furthermore, the cell viability tests of the FePt and FePt/Fe3O4 NCs demonstrated excellent biocompatibilities. Hence, the NCs could be useful for various biomedical applications, including MRI contrast agents, hyperthermia, and as a label in magnetic biochips.We demonstrated a simple one-pot synthesis approach for the controlled composition of homogeneous FePt and phase-controlled heterostructured FePt/Fe3O4 nanocubes (NCs) utilizing 1,2-hexadecanediol and 1-octadecene as the reducing agents, respectively. 相似文献

Purpose:To report the factors influencing eye donation among families of successful eye donors in India.Methods:The consenting family members of 434 deceased individuals who donated eyes between April 2019 and March 2020 were retrospectively interviewed via a telephonic questionnaire survey. Details regarding the donors and their families, motivating factors for eye donation, and time taken for tissue recovery were collected and analyzed.Results:The mean age of donors was 66.8 years, and only 13.9% of them had pledged to donate their eyes before death. For 62.3% of donations, children of donors were the primary consenters for eye donation. In 18.8% of donors, there was a previous history of eye donation in the family. Many donations were motivated by a non-governmental organization volunteer (40.5%) or by a grief counselor at the hospital (27.4%). Hospital-based corneal retrieval programs and donations where the first eye bank contact was made through hospital personnel had the greatest percentage of rapid enucleations (performed within 3 h after death) (48.7% and 49.1%, respectively; P = 0.001 and P = 0.02, respectively).Conclusion:Children of donors, typically in the working-age group, most often make the decision for donation, and hence, future awareness programs should focus on this specific population. All types of hospitals should advocate for eye donation as they are a common point of contact for a grieving family, and health-care professionals at all levels should be considered for training as motivators for eye donation. 相似文献

Vegetables are very important in the diet and provide minerals, vitamins, antioxidants and fiber. A beneficial role of dietary fiber in human nutrition is known but the data on the effect of maturity and processing of Indian vegetables on dietary fiber and its fractions are not available. Hence, the present study was undertaken to generate data on total (TDF), insoluble (IDF) and soluble (SDF) dietary fiber contents of green leafy vegetables (GLV) and to assess the effect of leaf maturity and cooking on these parameters. Sixteen GLV (namely, agathi, alternanthera, amaranth, basella, cabbage, colocasia, coriander, curry leaves, drumstick, fenugreek, hibiscus, mint, portulaca, rumex, spinach and tender tamarind leaves) were analysed for TDF, IDF and SDF by the enzymatic and gravimetric method of the Association of Official Analytical Chemists. Among the GLV analysed, the TDF and IDF contents were the lowest (2.5 g% and 1.6 g%) in basella and were the highest (16.3 g% and 13.4 g%) in curry leaves. The SDF content ranged from 0.7 g% in spinach to 2.9 g% in curry leaves. The SDF as a percentage of the TDF ranged from 11.3% in tender tamarind leaves to 36.0% in basella, but the majority of GLV had around 25% of the TDF as SDF. Significant (P<0.01) variation was observed between inter-species and intra-species in TDF, IDF and SDF contents of all the GLV. As the leaf matured from tender to mature and to coarse stage, the TDF and IDF contents of amaranth, basella, hibiscus, rumex and spinach increased significantly (P<0.05), The SDF content significantly (P<0.05) increased from tender to mature stage in all five GLV, but there was no further increase from mature to coarse stage except in rumex, where a significant (P<0.01) increase (25%) was observed. Processing/cooking of GLV had no significant effect on their TDF, IDF and SDF contents. 相似文献

Liver disease in HIV-infected patients has remained unaddressed in India. This study describes the causes of liver disease in HIV-infected patients and short-term outcome in them. Designed as a prospective observational study, it was conducted at Jawaharlal Institute of Postgraduate Medical Education and Research between September 2011 and March 2013. All consecutive HIV patients (>13 years) attending the antiretroviral therapy clinic or admitted in the Medicine Department were screened, and patients with liver disease or with either HBsAg or anti-HCV antibody positivity were included in the study. Of the 198 patients screened, 51 (26 %) had either abnormal liver function test or had HBsAg or anti-HCV positivity. The median age of the patients was 40 years and 82 % were males. The median CD4 count was 123 cells/mm3. Eighteen (35 %) of them had alcoholic liver disease. Six patients had probable hepatic involvement due to tuberculosis. Ten patients had antituberculosis drug-induced hepatotoxicity. One patient had acute hepatitis B and seven patients had chronic hepatitis B. The cause could not be established in 10 patients (20 %). After a median period of 8 months of follow up, 23 patients had improved, 19 patients (37 %) had died, and six patients had been lost to follow up. Of the patients who had died, 11 patients (58 %) had tuberculosis, and 6 patients (30 %) had decompensated alcoholic liver disease. In conclusion, liver disease in HIV-infected patients was associated with high mortality. Alcohol abuse, tuberculosis, and antituberculosis drugs were the major causes. 相似文献
