Colorectal cancer cell growth inhibition by linoleic acid is related to fatty acid composition changes     

Lu XF  He GQ  Yu HN  Ma Q  Shen SR  Das UN 《Journal of Zhejiang University. Science. B》2010,11(12):923-930

Polyunsaturated fatty acids (PUFAs) possess anti-cancer action both in vitro and in vivo. In the present study, we detected cell viability with methyl thiazolyl tetrazolium (MTT) assay and cell membrane permeability with propidium iodide (PI) fluorescence dyeing, and calculated cell membrane fluidity change as fluorescence anisotropy. Fatty acid content in cells was measured by gas chromatography/mass spectroscopy (GC/MS), and the relationship between fatty acid composition and cell viability was studied. We observed that n-6 PUFA linoleic acid (LA) inhibited tumor cell growth at high concentrations (≥300 μmol/L), while low concentrations (100–200 μmol/L) seemed to promote cell proliferation. Analyses of cell membrane permeability, cell membrane fluidity, and cell fatty acid composition suggested that the anti-cancer action of LA could be related to changes in the ratio of n-6 to n-3 PUFAs. We observed that pre-incubation of cancer cells with 100 μmol/L LA for 24 h enhanced cell sensitivity to the cytotoxic action of LA, whereas undifferentiated cell line LoVo seemed to have a distinct path in LA-induced death. These results showed that one of the mechanisms by which supplementation of LA induces cancer cell death could be altering the ratio of n-6/n-3 PUFAs, and this may be related to cell differentiation status.  相似文献   

多功能静电场描绘仪的改进     

林文广  李惠杉 《绵阳师范学院学报》2010,29(2):32-34

针对实验室普遍使用的几种静电场描绘仪的不足,改进并设计出一种多功能静电场描绘仪。该描绘仪在单层静电场描绘仪结构的基础上,也利用水为介质,其圆形水槽作为整个描绘仪的底座,同时用于放置实验时所要测量的金属导体。水槽上分别安装有万能转向接头和固定轴,用于安装探针固定杆和固定导体。在水槽两端分别装有可以绕着固定轴旋转的金属连杆,配合圆形水槽,金属连杆可用于复杂形状金属体的固定并完成其静电场的描绘,并可提高实验的检测精度。  相似文献   

Targeted yield concept and a framework of fertilizer recommendation in irrigated rice domains of subtropical India   总被引：1，自引：0，他引：1  

Bera R  Seal A  Bhattacharyya P  Das TH  Sarkar D  Kangjoo K 《Journal of Zhejiang University. Science. B》2006,7(12):963-968

Soil test crop response （STCR） correlation studies were carried out in Vindhyan alluvial plain during 2001 to 2004 taking IR-36 as test crop to quantify rice production in the context of the variability of soil properties and use of balanced fertilizers based on targeted yield concept. The soils were developed on gently sloping alluvial plain with different physiographic settings and notable variation in drainage condition. Soil properties show moderate variation in texture （loamy to clay）, organic carbon content （4.4 to 9.8 g/kg）, cation exchange capacity （10,2 to 22.4 cmol （p＋）/kg） and pH （5.3 to 6,4）, Soil fertility status for N is low to medium （224 to 348 kg/ha）, P is medium to high （87 to 320 kg/ha） and K ranges from medium to high （158 to 678 kg/ha）. Database regarding nutrient requirement in kg/t of grain produce （NR）, the percent contribution from the soil available nutrients [CS （%）] and the percent contribution from the applied fertilizer nutrients [CF （%）] were computed for calibrating and fbrmulating fertilizer recommendations. Validity of the yield target for 7 and 8 t/ha was tested in farmers＇ fields and yields targets varied at less than 10%. The percent achievement of targets aimed at different level was more than 90%, indicating soil test based fertilizer recommendation approach was economically viable within the agro-ecological zone with relatively uniform cropping practices and socio-economic conditions.  相似文献   

Lack of Circadian Pattern of Serum TNF-α and IL-6 in Patients with Fibromyalgia Syndrome     

Ghizal Fatima  Abbas Ali Mahdi  Siddharth Kumar Das  Baby Anjum  Nar Singh Verma  Puneet Kumar  Ragini Shrivastava 《Indian journal of clinical biochemistry : IJCB》2012,27(4):340-343

The present study was designed to test the hypothesis of a circadian variation in circulating levels of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) in women with fibromyalgia syndrome (FMS). Serum levels of IL-6 and TNF-α were measured at 4 h intervals of the day in 50 women with FMS satisfying American College of Rheumatology criteria for FMS (age 36.68 ± 9.89) as well as 50 healthy control women (age 32.82 ± 10.53). Serum TNF-α levels were substantially increased in patients with FMS but showed no circadian variation. In contrast, no difference in the levels of IL-6 was found. Moreover, there was also no circadian variation in both the groups of patients and controls. We conclude that no circadian pattern exists in the circulating levels of serum IL-6 and TNF-α in patients with FMS, although TNF-α levels are found raised in patients with FMS.  相似文献   

Vanishing species: The planet in crisis     

Uttam Saikia  Narayan Sharma  Abhijit Das 《Resonance》2010,15(4):321-336

Rapid extinction of species is one of the most serious ecological problems faced by humanity today. Species are disappearing at a pace unprecedented in the history of the planet putting the very future of life at risk. The irony is that the root of the crisis is another species, Homo sapiens rather than some physical events that is poised to threaten its own survival. This article gives a brief introduction to the crisis, its consequences and possible mitigation strategies.  相似文献
