AI Article Synopsis

  • Excess saturated fatty acids in diet can cause obesity, leading to issues like insulin resistance and inflammation.
  • Macadamia oil has been identified as a potential supplement that improves lipid profiles in humans, prompting research on its effects in mice.
  • In a study, mice on a high-fat diet showed reduced inflammation and less adipocyte hypertrophy when supplemented with macadamia oil, indicating its benefits in counteracting diet-induced obesity effects.

Article Abstract

Excess of saturated fatty acids in the diet has been associated with obesity, leading to systemic disruption of insulin signaling, glucose intolerance, and inflammation. Macadamia oil administration has been shown to improve lipid profile in humans. We evaluated the effect of macadamia oil supplementation on insulin sensitivity, inflammation, lipid profile, and adipocyte size in high-fat diet (HF) induced obesity in mice. C57BL/6 male mice (8 weeks) were divided into four groups: (a) control diet (CD), (b) HF, (c) CD supplemented with macadamia oil by gavage at 2 g/Kg of body weight, three times per week, for 12 weeks (CD + MO), and (d) HF diet supplemented with macadamia oil (HF + MO). CD and HF mice were supplemented with water. HF mice showed hypercholesterolemia and decreased insulin sensitivity as also previously shown. HF induced inflammation in adipose tissue and peritoneal macrophages, as well as adipocyte hypertrophy. Macadamia oil supplementation attenuated hypertrophy of adipocytes and inflammation in the adipose tissue and macrophages.

Oleogels can be formed using different types of oleogelator, which lead to different end properties. In this study, four kinds of oleogelators, rice bran wax (RBW), monoglyceride stearate (MG), beeswax (BW), and a mixture of β-sitosterol and γ-oryzanol (SO) were used to prepare astaxanthin-loaded macadamia oil-based oleogels. Fourier transform infrared spectroscopy, polarized light microscopy, X-ray diffraction, differential scanning calorimetry, and dynamic shear rheometry were then used to evaluate the effects of the different oleogelators and astaxanthin on the physicochemical properties of the oleogels.

Hyperlipidemia, characterized by an abnormal lipid metabolism, is related to multiple cardiovascular diseases that pose challenges to global public health. Macadamia oil (MO), rich in monounsaturated fatty acids (around 80%), is regarded as a functional oil used to regulate lipid accumulation. Nonetheless, the lipid-lowering mechanism of MO is still unknown.

Article Synopsis
  • The study investigated the impact of dietary macadamia oil (MO) on various health and growth metrics in rabbits, using four treatment groups over eight weeks.
  • Results showed that increasing levels of MO improved growth performance and health markers, with an optimal dosage of 1.25 mL/kg for the best outcomes.
  • Key findings included improved immune function and reduced inflammation, indicating that supplementing rabbits’ diets with MO can enhance overall health and growth traits.

Yield in many crops is affected by abscission during the early stages of fruitlet development. The reasons for fruitlet abscission are often unclear but they may include genetic factors because, in some crops, self-pollinated fruitlets are more likely to abscise than cross-pollinated fruitlets. Pollen parentage can also affect final fruit size and fruit quality.

Clinical Efficacy in Skin Hydration and Reducing Wrinkles of Nanoemulsions Containing Seed Oil.

Nanomaterials (Basel)

April 2024

Department of Pharmaceutical Sciences, Faculty of Pharmacy, Chiang Mai University, Chiang Mai 50200, Thailand.

This study aimed to assess natural oils for their antioxidant and anti-hyaluronidase properties and select the most effective candidate for development into nanoemulsions (NE) for clinical evaluations. The oils were assessed using 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid (ABTS) and ferric thiocyanate assays for antioxidant properties and an enzyme-substrate reaction assay for anti-hyaluronidase activity. The most potent oil was formulated into conventional emulsions (CE) and NE, which were characterized and evaluated for their stability, both in accelerated and long-term conditions.
