Fat transfer

AIM: Atractylodes macrocephala Rhizome (AM) has been used to treat hyperlipidemia for centuries, but its functional components and mechanisms are not clear. This research aimed to investigate the active components in AM and the mechanisms that underlie its anti-hyperlipidemia effect. METHODS: SD rats were fed a high-sucrose high-fat diet in conjunction with alcohol (HSHFDAC) along with different AM extracts (AMW, AMO, AME, and AMP) for 4 weeks. AM's active components were analyzed using multiple databases, and their mechanisms were explored through network pharmacology...

Obesity is a complex multicausal disease that can cause morbidity and mortality, and there is need for improved knowledge on the underlying mechanisms. Using a mouse model of increased T cell responsiveness, we show that development of obesity can be driven by immune cells. This was confirmed with bone marrow transplantation and adoptive T cell transfer to several recipient mouse models. Single-cell RNA sequencing and CyTOF analysis showed that the mice display altered composition of circulating T cells and increased T cell activation in visceral adipose tissue, suggesting activated T cells as critical players in the increased fat mass...

The aim of this study was to investigate the growth and development of animals produced from demi-embryos and compare them with whole embryos from fetus to adult life. To achieve this, calves produced from fresh demi-embryos and whole embryos were individually transferred and monitored from 60 days of pregnancy until slaughter at 550 days. Ultrasound scans were conducted on fetuses at 60 and 90 days to evaluate the biparietal, abdominal, umbilical cord, orbital, and aorta diameters. Subsequently, morphological traits of newborn calves were measured at 0, 7, and 21 days (N = 18)...

Background: The popularity of gluteal augmentation has surged in recent decades, primarily due to satisfactory aesthetic results. Objectives: The primary goal of this retrospective analysis was to present the key characteristics of a large patient cohort from Europe, comprising 185 female patients who underwent gluteal augmentation with ultrasound-guided fat grafting. Methods: A retrospective analysis was conducted on 185 female patients who underwent gluteal augmentation with ultrasonic liposuction and fat grafting from February 2020 to July 2023...

Food authorities aim to safeguard our food. This requires sensitive analyses to guarantee detection of both banned and regulated substances at low concentrations. At the same time, broad screening methods are needed to identify new emerging risks. For this purpose, effect-based bioassays combined with mass spectrometric analyses offer an advantage. During the regular monitoring of dioxins in agricultural products, a discrepancy was observed between the results of the DR CALUX (Dioxin-Responsive Chemical Activated Luciferase gene Expression) bioassay and the confirmatory gas chromatographic high resolution mass spectrometric (GC-HRMS) analysis in egg and broiler fat samples...

This study explores the impact of rotational frying of three different food products on degradation of sterols, as well as their migration between frying oils and food. The research addresses a gap in the existing literature, which primarily focuses on changes in fat during the frying of single food items, providing limited information on the interaction of sterols from the frying medium with those from the food product. The frying was conducted at 185 ± 5 °C for up to 10 days where French fries, battered chicken, and fish sticks were fried in succession...

BACKGROUND: Over the past 4 years, aesthetic surgery, notably liposuction, has substantially increased. Tumescent liposuction, a popular technique, has two variants-true tumescent liposuction (TTL) and semi-tumescent liposuction. While TTL reduces risks, it has limitations. There is no literature reported on semi-tumescent liposuction under deep sedation using the propofol-ketamine protocol, which is proposed as a potentially safe alternative. METHODS: The retrospective analysis covered 8 years and included 3094 patients performed for tumescent liposuction under deep sedation, utilizing the propofol-ketamine protocol...

Obesity and gestational diabetes (GDM) impact fetal growth during pregnancy. Iron is an essential micronutrient needed for energy-intense feto-placental development, but if mis-handled can lead to oxidative stress and ferroptosis (iron-dependent cell death). In a mouse model showing maternal obesity and glucose intolerance, we investigated the association of materno-fetal iron handling and placental ferroptosis, oxidative damage and stress signalling activation with fetal growth. Female mice were fed a standard chow or high fat, high sugar (HFHS) diet during pregnancy and outcomes were measured at day (d)16 or d19 of pregnancy...

BACKGROUND: The rejuvenation and restoration of a well-defined jawline contour are crucial for enhancing facial aesthetics in both men and women. Within the jawline aesthetic unit (mandibular angle), the masseter muscle plays a significant role, as it is responsible for mandibular masticatory movements. We propose a new approach using ultrasound-guided intramuscular fat transfer to enhance the mandibular angle and jawline. METHODS: The multicenter study included 20 patients from three countries (Peru, Brazil, and Mexico)...

Glycosylphosphatidylinositol-anchored proteins (GPI-APs) are anchored at the outer phospholipid layer of eukaryotic plasma membranes exclusively by a glycolipid. GPI-APs are not only released into extracellular compartments by lipolytic cleavage. In addition, certain GPI-APs with the glycosylphosphatidylinositol anchor including their fatty acids remaining coupled to the carboxy-terminus of their protein components are also detectable in body fluids, in response to certain stimuli, such as oxidative stress, radicals or high-fat diet...

Biodiesel is a highly promising and viable alternative to fossil-based diesel that also addresses the urgent need for effective waste management. It can be synthesized by the chemical modification of triglycerides sourced from vegetable origin, animal fat, or algal oil. The transesterification reaction is the preferred method of producing biodiesel. However, the non-miscibility of alcohol and oil layer causes excessive utilization of alcohol, catalyst, and a substantial reacting time and temperature. In the current investigation, transesterification of waste fish oil was performed with petro-diesel as cosolvent, under the influence of ultrasound energy...

BACKGROUND: Autologous breast reconstruction confers favorable patient reports of satisfaction and quality of life compared to implant-based reconstruction over a lifetime. The latissimus dorsi with immediate fat transfer (LIFT) is an alternative approach to abdominally based free flaps (Ab-FF), which expands fully autologous reconstruction to non-microsurgeons. This study aims to compare the two procedures concerning their clinical and patient-reported outcomes one year postoperatively...

Skin has been shown to be a regulatory hub for energy expenditure and metabolism: mutations of skin lipid metabolism enzymes can change the rate of thermogenesis and susceptibility to diet-induced obesity. However, little is known about the physiological basis for this function. Here we show that the thermal properties of skin are highly reactive to diet: within three days, a high fat diet reduces heat transfer through skin. In contrast, a dietary manipulation that prevents obesity accelerates energy loss through skins...

INTRODUCTION: Autologous fat transfer (AFT) is widely used to improve results of breast reconstructive surgery, but its safety is controversial. Our objective was to evaluate the oncologic safety of AFT in a homogeneous population of patients who underwent a total mastectomy with immediate reconstruction for breast cancer. METHODS: We performed a retrospective cohort study by identifying all patients who underwent immediate breast reconstruction after mastectomy for breast cancer from 2007 to 2015 in our center...

Gemlik is a cultivar that grows in a distinct region of Turkiye and is ideal for brine fermentation of brine black table olives. Bursa Protected Designated Origin (PDO) and Izmir non-PDO Gemlik table olives have high levels of oleic acid (74%), total phenol (190 mg/kg), and dry matter (57%), while being low in linoleic acid (8%). The pH values and salt contents were observed to be in the range of 4.1 to 4.3 and 3.9% to 4.8%, respectively. During the fermentation of Gemlik table olives, a mass transfer occurred, resulting in a reduction in reducing sugar and total sugar contents as well as an increase in the salt content of the olives...

Combination antiretroviral therapy (cART) has markedly increased life expectancy in people with HIV (PWH) but has also resulted in an increased prevalence of cardiometabolic disorders, whose etiopathology remains ill-defined. Notably, the respective contribution of cART and HIV-derived proteins to obesity and vascular alterations remain poorly understood. Therefore, we investigated the individual and combined effects of HIV-proteins and of the integrase strand transfer inhibitor Dolutegravir (DTG) on body composition and vascular reactivity...

HYPOTHESIS: The key feature of living cells is multicompartmentalization for enzymatic reactions. Artificial cell-like multicompartments with micro domains are appealing to mimic the biological counterparts. In addition, establishing a sustainable, efficient, and controllable reaction system for enzymatic hydrolysis is imperative for the production of natural fatty acids from animal and plant-based fats. EXPERIMENTS: Reverse Janus emulsion microreactors, i.e. (W1  + W2 )/O, is constructed through directly using natural fats as continuous phase and aqueous two-phase solutions (ATPS) as inner phases...

Foodborne carbon dots (CDs) are generally produced during cooking and exist in food items. Generally, CDs are regarded as nontoxic materials, but several studies have gradually confirmed the cytotoxicity of CDs, such as oxidative stress, reduced cellular activity, apoptosis, etc. However, studies focusing on the health effects of long-term intake of food-borne CDs are scarce, especially in populations susceptible to metabolic disease. In this study, we reported that CDs in self-brewing beer had no effect on glucose metabolism in CHOW-fed mice but exacerbated high-fat-diet (HFD)-induced glucose metabolism disorders via the gut-liver axis...

This study aimed to examine the distribution of anaerobic bacteria in the rumen fluid of Thai crossbred goats and to screen potential probiotic strains capable of producing antimicrobial compounds and inhibiting bacteria that cause milk fat depression. Thirty-four strains of bacteria from the rumen fluid were divided into 13 groups within 12 genera based on 16S rRNA gene sequences. The RF1-5 and RF5-12 were identified as Streptococcus luteliensis and Bacillus licheniformis, respectively, and demonstrated non-ropy exopolysaccharide...
