Mineral composition of iron chlorotic citrus limon L. leaves     

J. A. Fernandez‐Lopez  J. M. Lopez‐Roca  L. Almela 《Journal of plant nutrition》2013,36(8):1395-1407

A field experiment was conducted to evaluate the effect of iron (Fe) chlorosis on the mineral composition of lemon tree leaves cultivated in calcareous soil in the region of Murcia, Spain. A Fe‐polyflavonoid was employed as fertilizer to control Fe deficiency. The evolution of the leaf content in Fe, potassium (K), sodium (Na), magnesium (Mg), calcium (Ca), phosphorus (P), manganese (Mn), and zinc (Zn) was monitored during all the sampling cycle. A high correspondence between total Fe and chlorophyll content could be appreciated. A multivariance analysis was performed with the data obtained, showing that Fe was correlated with P, Mn, and K.  相似文献   

Fatty acid,amino acid,and trace mineral analyses of five weaning foods from Jos,Nigeria     

Fernandez DR  Vanderjagt DJ  Williams M  Huang YS  Chuang LT  Millson M  Andrews R  Pastuszyn A  Glew RH 《Plant foods for human nutrition (Dordrecht, Netherlands)》2002,57(3-4):257-274

Five plant-based weaning foods (WF) (Dietrend, Jot-M, Soy, Ang and Vic-T) locallyprepared in Jos, Nigeria were analyzed by gas-liquid chromatography,reverse-phase high performance liquid chromatography, and atomicemission spectrometry with inductively coupled plasma to determine theirfatty acid (FA), amino acid, and trace mineral contents, respectively.Results of these direct analyses were compared to expected values derivedfrom food composition tables prepared by the United States Department of Agriculture (USDA). Additionally, results were compared against recommendednutrient values, using breast milk as the standard for FA content andrecommended dietary allowances (RDA) for amino acid and mineral contents.The overall nutritional value of the five WF varied considerably and thequantities of particular nutrients determined by direct analysis differedmarkedly from those estimated using USDA food tables. Comparison of WFfatty acid composition relative to the RDA recommendations and a humanmilk standard revealed a much higher proportion of both linoleic (35–55wt%) and -linolenic acids (1%–7 wt%) relative to human milklipids (11%–12% and 0.8%–0.9% wt, respectively); however, the WFwere devoid of arachidonic acid and docosahexaenoic acid. Soy containedthe highest amounts of linoleic acid (59.7 mg/g) and -linolenicacid (7.46 mg/g) compared to the other four WF (10.2–41.0 and 0.35–3.18 mg/g, respectively). The linoleic acid/-linolenic acid ratio was within the recommended range (5:1 to 10:1) in only Jot-M (10:1)and Soy (8:1). Dietrend, Vic-T and Ang, containedlinoleic/-linolenic ratios of 12:1, 29:1, and 82:1, respectively.The Soy weaning food would provide the most protein (24.3 g/day), basedon an estimated daily intake of 65 g of weaning food by a normalsix-month-old infant, compared to Jot-M (11.9 g/day), Dietrend (11.7g/day), Ang (8.07 g/day) and Vic-T (7.26 g/day). The protein RDA forchildren up to 1 year of age is 13–14 g/day. Comparison of the mineralcontents of the WF to the RDAs for various minerals indicated that all fivewould provide suboptimal amounts of calcium (16 to 250 mg/day) andzinc (1.42 to 3.56 mg/day) compared to respective RDAs of400 mg/day and 5 mg/day.These data show that the Soy weaning food is an excellent source of linoleicacid and -linolenic acid, as well as being a good source of highquality protein. Jot-M and Dietrend provide useful amounts of the essentialFA; however, it is advisable to reevaluate the composition of Ang andVic-T to find ways to improve the linoleic/-linolenic ratio of eachand increase their total protein content. These results document theshortcomings of using published food composition tables based on foods inAmerica when devising weaning foods based on ingredients in another partof the world.  相似文献   

Ciguatera Fish Poisoning: Treatment,Prevention and Management          下载免费PDF全文

Ciguatera Fish Poisoning (CFP) is the most frequently reported seafood-toxin illness in the world, and it causes substantial physical and functional impact. It produces a myriad of gastrointestinal, neurologic and/or cardiovascular symptoms which last days to weeks, or even months. Although there are reports of symptom amelioration with some interventions (e.g. IV mannitol), the appropriate treatment for CFP remains unclear to many physicians. We review the literature on the treatments for CFP, including randomized controlled studies and anecdotal reports. The article is intended to clarify treatment options, and provide information about management and prevention of CFP, for emergency room physicians, poison control information providers, other health care providers, and patients.  相似文献   

过瘤胃脂肪在奶牛日粮中的应用     

J.I.Fernandez  李树聪  唐文花 《中国畜牧兽医》2000,27(3):14-15

高产奶牛—产奶量为9000L/头·泌乳期对营养的需要与普通奶牛有很大差别。在生产中,满足高产奶牛蛋白质和其它营养成分的需要比较容易,但是它们的能量需要却不能简单地通过谷物饲料来满足,尤其是在整个泌乳期的前1/3阶段。因此,在奶牛产后的一段时间内,必须为其提供更多的能量,以尽可能减少体重损失,而且,在泌乳早期增加能量供给量的同时不能影响瘤胃的正常活力。这也意味着维持高产奶牛的能量需要是非常重要的。因此,选择一种合适的“过瘤胃”脂肪是重要的。增加奶牛能量摄入量的常用方法有3种:增加干物质的摄入量,提高精料比例,提高日粮…  相似文献   

Agroforestry systems with Ilex paraguariensis (American holly or yerba mate) and native timber trees on small farms in Misiones, Argentina     

B. Eibl  R. A. Fernandez  J. C. Kozarik  A. Lupi  F. Montagnini  D. Nozzi 《Agroforestry Systems》2000,48(1):1-8

In Misiones, in the northeast of Argentina, agroforestry systems of timber trees and perennial cash crops are becoming increasingly common. We evaluated the productivity of Ilex paraguariensis St Hill (South American holly or yerba mate, Aquifoliaceae) in association with indigenous trees: Enterolobium contortisiliquum (Vellozo) Morong. (timbó, Leguminosae, a N₂-fixing tree), and two timber species, Balfourodendron riedelianum (Engler) Engler (guatambú, Rutaceae) and Tabebuia heptaphylla (Vellozo) Toledo (lapacho negro, Bignoniaceae). Five years after planting, the tree species were 2.7 to 5.0 m high and 3 to 7 cm in diameter at breast height, and the yerba mate produced its first harvest. Additionally, the production of associated crops of subsistence covered the annual needs of the farmer. These systems are promising for sustainable use of deforested lands in the region.This revised version was published online in November 2005 with corrections to the Cover Date.  相似文献

Viral antigen distribution in the central nervous system of cattle persistently infected with bovine viral diarrhea virus     

A Fernandez  M Hewicker  G Trautwein  J Pohlenz  B Liess 《Veterinary pathology》1989,26(1):26-32

Distribution of viral antigens in the central nervous system of 25 cattle with a persistent bovine viral diarrhea virus (BVDV) infection was studied. Using a polyclonal antiserum produced in pigs and the direct immunofluorescence and immunoperoxidase technique, BVDV antigen was located exclusively in neurons. Predilection sites for viral persistence were cerebral cortex and hippocampus; in other areas of brain and spinal cord, viral antigens were in single neurons or small groups of neurons. There was no morphological evidence of cellular alteration due to viral persistence. Perivascular lymphocytic infiltrations were in affected nervous tissue. It is concluded that the central nervous system is an important location for persistence of BVDV.  相似文献
