Evaluation of hydrothermal pretreatment and fermentation to improve lipid and ethanol production from corn germ meal
… and use of marginal lands. However, low concentrations of lipids in current engineered plant biomass samples makes extracting the oil challenging and expensive. The objectives of this work were to use hydrothermal pretreatment on oil bearing biomass for lipid enrichment and to investigate …

Genotypic differences and water stress-induced changes in lipids of maize hybrids
… and compared for inherent differences in lipid concentration and composition. These seedlings were also evaluated for their ability to tolerate mild osmotic stresses (-0.4 and -0.6 MPa, polyethylene glycol-induced), osmotically induced changes in lipid composition, and differences in …

Hormonal control of flight metabolism in Odonata?
… Injection of Ani-AKH (3.4 pmol) increased the concentration of haemolymph lipids in A. imperator. Lia-AKH (l pmol) similarly had an adipokinetic effect in 0. julia. Psi-AKH (I pmol) had an adipokinetic effect, as well as a small hyperglycaemic effect in P. inconspicuum. The AKH peptides of …

Fibrin targeting microbubbles for the detection of nascent surgical adhesions
… and non-targeted microbubbles made from three lipid types (soy phosphatidylcholine (SPC), hydrogenated soy phosphatidylcholine (HSPC) and distearoylphosphatidylcholine (DSPC)) were compared to show the effect of lipid saturation and targeting protein conjugation on microbubble stability and …

Self-assembling biomimetic hydrogels with bioadhesive properties for tissue engineering applications
… with tissue. Extracellular matrix (ECM) loaded lipid vesicles (liposomes) were incorporated into the copolymer for enhanced cellular biocompatibility. The bioadhesive strength was evaluated in contact with porcine ear cartilage. Additionally, the cytotoxicity of the samples was investigated …

The Effect of Constant Relative Growth Rate Versus Constant Specific Growth Rate on Oocystis SP
… done: CN content, the extracted chl <em>a</em> concentration, lipid concentration using Nile Red stain, and the ash free dry weight. The results of this study indicated that the cultures grown most likely did not undergo nutrient stress except during GS1 at 20°C. Given the results under these …

Development of environmentally benign microencapsulation with polymer microspheres and liposomes
… the great potential posed by bio-mimetic phospholipids in drug delivery, commercial products are quite limited. To address the structure stability of liposome based microencapsulationm in a more fundamental level, we studied the mechanism of spontaneous formation of monodispersed unilamellar …

Determination of effects of physical activity and adiposity on human thigh composition using magnetic resonance techniques
… gross adipose tissue depots and intramuscular lipid concentrations towards developing and substantiating the use of MRI/MRS to measure muscle quality. Secondary objectives were to quantify the differences between the three distinct groups: obese (O); lean and sedentary (LS), and lean and active …

The Effects of Pesticide Exposures on the Nutritional and Immune Health of the Honey Bee, Apis mellifera L.
… immune health of the honey bee. Total protein concentration was significantly reduced in the coumaphos- and chlorothalonil-treated individuals compared to the pesticide-untreated bees. Total carbohydrate concentration was significantly reduced in the tau-fluvalinate-, coumaphos-, and …

Development and Evaluation of Brain Tumor Targeted Liposome Delivery System for Paclitaxel
… and DSPE-PEG-biotin were prepared by the lipid film hydration and extrusion process. Transferrin (Tf) with affinity for transferrin receptors over-expressed on blood brain barrier and glioma tumor vasculature were coupled to the distal end of poly ethylene glycol coated long circulating …

Effect of UV-A irradiance on lipid accumulation in Nannochloropsis oculata
… and can accumulate a considerable amount of lipids. Their lipids can be grouped into two categories, storage lipids, which are mainly triglycerides (TGs), and structural lipids, which are composed of polyunsaturated fatty acids (PUFAs). PUFAs are essential nutrients for both aquatic animals …

Influence of osmotic stress, ethanol, and a substituted pyridazinone, BAS 13-338, on the growth and lipid composition of two Chlorella species
… and for osmotically-induced changes in lipid composition. C. vulgaris growth was inhibited as osmotic potentials decreased, while C. pyrenoidosa growth was moderately inhibited at -2.0 hPa. C. vulgaris produced increasing concentrations of triglycerides and sterol esters and decreasing …

Lattice Boltzmann method for integrating the Bloch equation in muscle fibers and microvessels
… properties of directional water diffusion and lipid concentration in the human muscle. Strong correlations have also been found between overall fitness and MRI measurements related to the transport of water inside the muscle fibers. In addition to water diffusion within the muscle, MR imaging …

The effects of an exercise training program on serum cholesterol and triglyceride levels in women using oral contraceptives
… lower serum cholesterol and/or triglyceride concentration in women using oral contraceptives. The intensity of the training was maintained at approximately 75% of the subject's pre-training maximal oxygen uptake. Comparisons were made in the variables triglyceride, cholesterol, maximum …

Microfluidics technology for the formulation design and production of liposomal products
… In particular, a high FRR (3:1 FRR) and initial lipid concentration of above 3 mg/mL were shown to be the two most important factors when producing small homogenous liposomes (< 100 nm). Also, a scalable manufacturing model was developed without the need for bespoke equipment, using readily …

Effect of Long-Chain Fatty Acids on Anaerobic Digestion
… tested. LCFAs were added to sewage sludge at concentrations ranging from 5% to 20% on a weight basis and the pH, solids reduction and COD reduction were determined. The results suggested that in addition to degrading in the digesters, all unsaturated acids contributed additional solids …
