Background: Liposuction is a procedure to reduce the volume of subcutaneous fat by physical force. Intracellular storage fat is composed of triglyceride, whereas circulating fat particles exist as cholesterol or triglycerol bound to carrier proteins. It is unavoidable that the storage form of fat particles enters the circulation system after these particles are physiologically destroyed. To date, however, no studies have clarified the fatal characteristics of fat embolism that occurs after the subclinical phase of free fat particles.
Methods: A mixture of human lipoaspirate and normal saline (1:100, 0.2 mL) was injected into the external jugular vein of rats, weighing 200 g on average. Biopsy specimens of the lung and kidney were examined at 12-hour intervals until postoperative 72 hours. The deposit location and transport of the injected free fat particles were confirmed histologically by an Oil Red O stain.
Results: Inconsistent with previous reports, free fat particles were transported from the intravascular space to the parenchyma. At 24 hours after infusion, free fat particles deposited in the vascular lumen were confirmed on the Oil Red O stain. At 72 hours after infusion, free fat particles were accumulated compactly within the parenchymal space near the perivascular area.
Conclusions: Many surgeons are aware of the fatal results and undiscovered pathophysiologic mechanisms of free fat particles. Our results indicate that free fat particles, the storage form of fat that has been degraded through a physiological process, might be removed through a direct transport mechanism and phagocytotic uptake.

Background: The cerebral circulation is continuously challenged by intravascular micrometer-sized particles that become trapped microvascular-emboli. These particles may include micro-thrombi, stiffened erythrocytes, and leukocytes, while also fat particles, air, and microplastics may cause microvascular embolism.
Review Scope: In this narrative review, we discuss these embolization processes and their acute and chronic consequences.

This study investigated the effect of refining time on the physicochemical and functional properties of anhydrous cream prepared from a palm-sunflower oil blend using a stirred ball mill. Refining was performed for 0-300 min, and its impact on particle size distribution, rheology, oxidative stability, and thermal behavior was assessed. The target particle fineness (D90 ≤ 30 μm) was achieved at approximately 180 min, with negligible reduction thereafter.

Background And Aim: The global demand for efficient poultry production necessitates alternatives to antibiotic growth promoters. This study aimed to evaluate the effects of a novel four-component organic-mineral feed additive (OMFA), comprising lactulose, arginine, ultrafine silicon dioxide particles, and succinic acid, and a three-component variant (without lactulose) on growth performance, nutrient digestibility, elemental tissue composition, and the cecal microbiota of Arbor Acres broiler chickens.
Materials And Methods: One hundred and five one-day-old broiler chicks were randomly allocated into three groups: Control, Group I (four-component OMFA), and Group II (three-component OMFA).

Raw milk is commonly stored at 4 °C prior to processing, a practice that can facilitate psychrotrophic proliferation, and milk physicochemical alterations and quality deterioration. This study aimed to elucidate the dynamic changes and interrelationships among microbiota, physicochemical parameters, and metabolite profiles in raw bovine and goat milk during refrigerated storage at 4 °C over a 5-day period. The results showed that both bovine and goat milk exhibited significant increases in bacterial counts, titratable acidity, zeta potential, and protein particle size, alongside decreases in pH and lipid particle size, as well as changes in color during refrigerated storage at 4 °C.

Turmeric (Curcuma longa) exhibits anti-obesity properties, yet its low water solubility limits bioavailability. In this study, a water-dispersible turmeric rhizome extract (WDTE) was developed using nano-dispersion technology with maltodextrin as a wall material and characterized by UPLC-QTOF-MS, dynamic light scattering, and zeta potential analysis. The WDTE contained 10 identified metabolites, including five diarylheptanoids such as curcumin, demethoxycurcumin, and bisdemethoxycurcumin, with curcumin quantified at 7.
