Discuss or comment on this article.
Sterol regulatory element binding protein- 1 and -2 (SREBP-1 and -2) are key transcription factors involved in the biosynthesis of cholesterol and fatty acids. The SREBP have mostly been studied in rodents in which lipogenesis is regulated in both liver and adipose tissue. There is, though, a paucity of information on birds, in which lipogenesis occurs essentially in the liver as in humans. Since a prelude to the investigation of the role of SREBP in lipid metabolism regulation in chicken, we review Size and Tissue expression Pattern of SREBP and role of this protein in chickens.

Conclusions:
The positive associations between the DIs and measures of adiposity (BMI and percent body fat) support increased desaturase activity in obesity. The lower vaccenic/stearic DI in DD SAT compared with Controls suggests presence of other factors involved in fat accumulation in addition to lifestyle. Other mechanisms driving fat accumulation in DD such as inflammation or lymphatic dysfunction should be investigated. (Source: Lipids in Health and Disease)

AbstractWe performed a survey on the yield, quality, and chemical characteristics of virgin olive oils from two olive varieties in Croatian Istria: Frantoio and Ascolana tenera, on Cherry leafroll virus‐infected and virus‐noninfected trees and on two harvest dates. Free acidity, peroxide value, specific spectrophotometric absorptions at 232 and 270 nm, fatty acid composition, total phenols, o‐diphenols, oil color, and pigments were determined. Infected olives had lower oil yield and maturity index versus healthy ones. Oils from infected fruits had significant lower value of K232 and K270 and very elevated total phe...

Save this article to My Clippings.
Discuss or comment on this article.
Background:
Obesity is known to be associated with higher risks of cardiovascular disease, metabolic syndrome, and diabetes mellitus. Thyroid-stimulating hormone (TSHR) is the receptor for thyroid-stimulating hormone (TSH, or thyrotropin), the key regulator of thyroid functions. The expression of TSHR, once considered to be limited to thyrocytes, has been so far detected in many extrathyroidal tissues including liver and fat. Previous studies have shown that TSHR expression is upregulated when preadipocytes differentiate into mature adipocytes, suggestive of a possible role of TSHR in adipogenesis. However, it remains uncl...

Discuss or comment on this article.
Conclusions:
Dietary n-3 PUFA enrichment may improve the immune response and IBD resistance, but the optimum performance does not coincide with the optimum immune response. It seems that dietary n-3 PUFA modulates the broiler chicken performance and immune response in a dose-dependent manner. Thus, a moderate level of dietary n-3 PUFA enrichment may help to put together the efficiency of performance and relative immune response enhancement in broiler chickens.

Conclusions:
The torque%, viscosity (cp) and SS (dyne/cm2) of all GNP sizes decreased with increasing the temperature and with decreasing the GNP size (for each fixed temperature value).

This study demonstrates that the physical, dimensional and morphological changes of GNPs have effective influence on their rheological properties. To understand and categorize the role of GNPs in drug delivery and cancer therapy, GNPs of varying size, number of particles, shape and surface should be taken into consideration.

AbstractSummary: The main proposal of this study was to evaluate whether cold‐pressed flaxseed oil (CFO), vitamin E‐enriched hot pressed and totally refined flaxseed oils (HRFO) characterized by different qualities of micronutrients would have beneficial effects on lipid profile and antioxidant status in high‐fat fed rats. Male Wistar rats were fed synthetic diets containing 10% of HRFO, CFO, low‐dose (100 mg/100g oil) vitamin E‐enriched HRFO (L‐HRFO) or high‐dose (200 mg/100g oil) vitamin E‐enriched HRFO (H‐HRFO) respectively for 4 weeks.

AbstractSummary: Determination of the main phytosterols (β‐sitosterol and campesterol) and cholesterol precursors (desmosterol and lathosterol) in human serum using a simple gas chromatography‐flame ionization detector (GC‐FID) method has been validated. Direct saponification, without lipid extraction, sterols extraction and further derivatization was applied to samples prior to GC analysis. To evaluate the method, a pool of serum samples from 8 healthy women was used. Good linearity (r > 0.99) was found in the assay range: β‐sitosterol (0.99‐17.82 µg/mL), campesterol (0.14‐10.8 µg/mL), desmoster...

This study is concerned with the effect of the process of roasting of naked pumpkin seeds prior to its pressing on the chemical composition and oxidative stability of the extracted oil. Ground seeds were roasted at temperatures of 90, 110 and 130 °C for 30 and 60 min, according to the traditional technology of production of roasted pumpkin oil. Depending on the roasting conditions of the seeds, this treatment resulted in a significant increase of the contents of phospholipids (from 0.005 to 0.463%), total phenolic compounds (from 4.63 to 19.60 mg/kg), and total tocopherols (from 265.79 to 350.98 mg/kg) in oil. Highe...
