Ya-Jie Cui, Chun-Lan Song, Yi-Bing Cheng
A boy aged 11 years was admitted due to intermittent weakness and difficulty in walking for 6 years, and hepatomegaly, glycopenia and unconsciousness for 4 years. The laboratory examinations showed severe metabolic acidosis, hypoglycemia, and abnormal liver function. CT scan showed marked liver enlargement with fat density shadow. The boy was given fluid infusion, correction of acidosis, intravenous injection of glucose, L-carnitine, compound vitamin B, and coenzyme Q10, but he was in a persistent coma and it was difficult to correct refractory metabolic acidosis and hypoglycemia...

Background: Fat grafting is a common procedure in plastic surgery but associated with unpredictable graft retention. Adipose tissue (AT) "product" quality is affected by the methods used for harvest, processing and transfer, which vary widely amongst surgeons. Currently, there is no method available to accurately assess the quality of AT. Objectives: In this study, we present a novel method for the assessment of AT product quality through direct measurements of oxygen consumption rate (OCR)...

Mycobacterium tuberculosis (Mtb) primarily resides in the lung but can also persist in extrapulmonary sites. Macrophages are considered the prime cellular habitat in all tissues. Here we demonstrate that Mtb resides inside adipocytes of fat tissue where it expresses stress-related genes. Moreover, perigonadal fat of Mtb-infected mice disseminated the infection when transferred to uninfected animals. Adipose tissue harbors leukocytes in addition to adipocytes and other cell types and we observed that Mtb infection induces changes in adipose tissue biology depending on stage of infection...

Aims: The role of CD4+ T cells in atherosclerosis has been shown to be dependent on cytokine cues that regulate lineage commitment into mature T helper subsets. In this study we tested the roles of IL-1R1 and MyD88 signaling in CD4+ T cells in atherosclerosis. Methods and results: We transferred apoe-/-myd88+/+or apoe-/-myd88-/- CD4+ T cells to T- and B-cell-deficient rag1-/-apoe-/- mice fed high fat diet. Mice given apoe-/-myd88-/- CD4+ T cells exhibited reduced atherosclerosis compared to mice given apoe-/-myd88+/+ CD4+ T cells...

BACKGROUND: Fat grafting is a popular soft tissue filler method; however, its results are variable and technique-dependent. Macrophages are present in fat grafts and closely associated with tissue regeneration. We hypothesized that activation/depletion of early macrophages in transferred fat improves/impairs fat graft survival. METHODS: Mouse inguinal fat (~150 mg) was transferred autologously. Fat grafting was first performed without other manipulations to obtain baseline information...

Background: Unpredictable volume maintenance in the long term is a major limitation of autologous fat grafting. Objectives: The authors compared results of autologous lipotransfer to the face with or without enrichment of fat with the stromal vascular fraction (SVF). Methods: Thirty patients with asymmetric depletion of facial volume were included in a prospective study. Patients were randomly assigned to undergo a single session of autologous fat transfer with washed adipose tissue (control group) or with washed adipose tissue combined with the pellet of centrifuged lipoaspirate, which contained the SVF (enriched group)...

For wheelchair users, a common injury is a sitting-acquired pressure ulcer (PU) which typically onsets near the interface between the ischial tuberosity (IT) and the overlying soft tissues. The risk of developing PUs can be reduced considerably if an adequate cushion is placed on the wheelchair in order to protect tissues from PUs by minimising interface mechanical loads between the body and cushion and also, exposure to internal soft tissue loads. In this work, we studied the biomechanical performances of an off-loading (OL) cushion with limited adjustability, in comparison to a standard foam cushion and a fully adjustable air-cell-based (ACB) cushion...

There are different modalities for hand rejuvenation. Fractional Er:YAG laser and long pulse Nd:YAG laser were introduced for treating hand wrinkles. We plan to compare fractional Er:YAG laser and long pulse Nd:YAG laser in a randomized controlled double-blind design with multiple sessions and larger sample size in comparison with previous studies. Thirty-three participants with hand wrinkles entered this study. They were randomly allocated to undergo three monthly laser treatments on each hand, one with a fractional Er:YAG laser and the other with a long pulse Nd:YAG laser...

Previously, we demonstrated that a grape seed procyanidin extract (GSPE) supplementation in pregnant and lactating rats exerted both healthy and deleterious programming effects on their offspring. Here, we evaluated whether the administration of GSPE during lactation (100 mg.kg(-1).day(-1)) in rats elicited beneficial effects in their normoweight (STD-GSPE group) and cafeteria-fed obese (CAF-GSPE group) adult male offspring. STD-GSPE and CAF-GSPE offspring showed increased energy expenditure and circulating total and high-molecular-weight adiponectin...

Defects in the biosynthesis of phospholipids and neutral lipids are associated with cell membrane dysfunction, disrupted energy metabolism, and diseases including lipodystrophy. In these pathways, the 1-acylglycerol-3-phosphate acyltransferase (AGPAT) enzymes transfer a fatty acid to the sn-2 carbon of sn-1-acylglycerol-3-phosphate (lysophosphatidic acid/LPA) to form sn-1, 2-acylglycerol-3-phosphate (phosphatidic acid/PA). PA is a precursor for key phospholipids and diacylglycerol. AGPAT1 and AGPAT2 are highly homologous isoenzymes and are both expressed in adipocytes...

Tissue engineering chamber (TEC) is a technique that could incubate up to 16 folds volume increase of a fat flap. But the mechanism in the silicone chamber was still unknown. The function of exudate in the chamber was noticed recently. We developed a special model called fluid drainage model (FDM) that consisted of a traditional TEC on the back and paired fat flaps without a chamber in the groins. Then we used a silicon tube to dynamically transfer the exudate from dorsal TEC to one of the paired inguinal fat flap while the other inguinal fat flap with a sham tube was set as control...

An 8-week feeding experiment was conducted to determine the effect of dietary betaine levels on the growth performance, antioxidant capacity, and lipid metabolism in high-fat diet-fed blunt snout bream (Megalobrama amblycephala) with initial body weight 4.3 ± 0.1 g [mean ± SEM]. Five practical diets were formulated to contain normal-fat diet (NFD), high-fat diet (HFD), and high-fat diet with betaine addition (HFB) at difference levels (0.6, 1.2, 1.8%), respectively. The results showed that the highest final body weight (FBW), weight gain ratio (WGR), specific growth rate (SGR), condition factor (CF), and feed intake (FI) (P < 0...

The aim of the present study was to test the hypothesis that leptin can directly mediate the negative effect of maternal obesity on preimplantation embryos. As previously shown, maternal obesity retards early embryonic development in vivo and increases the incidence of apoptosis in blastocysts. When two-cell embryos isolated from control and obese mice were transferred to identical (leptin free) conditions in vitro, no differences in any growth or quality parameters were recorded, including apoptosis incidence in blastocysts...

BACKGROUND: Recurrent carpal tunnel syndrome is often associated with perineural scarring around the median nerve. Surgical options include relatively invasive procedures, such as fat pad grafting, ligament reconstruction, muscle transfer, and nerve wraps. All have limited success because of the possibility of repeated recurrent scarring postoperatively. METHODS: We discuss a technique involving injection with external hydroneurolysis of the median nerve under ultrasound guidance for recurrent carpal tunnel...
