Wireless powering could enable the long-term operation of advanced bioelectronic devices within the human body. Although both enhanced powering depth and device miniaturization can be achieved by shaping the field pattern within the body, existing electromagnetic structures do not provide the spatial phase control required to synthesize such patterns. Here, we describe the design and operation of conformal electromagnetic structures, termed phased surfaces, that interface with non-planar body surfaces and optimally modulate the phase response to enhance the performance of wireless powering...

BACKGROUND: Breast augmentation is an elective surgery used to increase the size of the breast in females. This study was undertaken to determine the breast augmentation in Pakistani females. METHODS: From 2006 to 2011, 43 female patients who underwent breast augmentation via infra-mammary, periareolar, trans-umbilical and fat transfer were enrolled. For augmentation, saline-filled or gel-filled implants were used in the supine position under general anesthesia and local infiltration of adrenaline (1:100,000 dilution) on each side...

Type 2 diabetes mellitus (T2DM) is a common complication of obesity. Here, we have shown that activation of the IgG receptor FcγRIIB in endothelium by hyposialylated IgG plays an important role in obesity-induced insulin resistance. Despite becoming obese on a high-fat diet (HFD), mice lacking FcγRIIB globally or selectively in endothelium were protected from insulin resistance as a result of the preservation of insulin delivery to skeletal muscle and resulting maintenance of muscle glucose disposal. IgG transfer in IgG-deficient mice implicated IgG as the pathogenetic ligand for endothelial FcγRIIB in obesity-induced insulin resistance...

Mammary epithelial cells (MEC) secrete fat in the form of milk fat globules (MFG) which are found in milk in diverse sizes. MFG originate from intracellular lipid droplets, and the mechanism underlying their size regulation is still elusive. Two main mechanisms have been suggested to control lipid droplet size. The first is a well-documented pathway, which involves regulation of cellular triglyceride content. The second is the fusion pathway, which is less-documented, especially in mammalian cells, and its importance in the regulation of droplet size is still unclear...

REVIEW
Junjeong Choi, Yoon Jin Cha, Ja Seung Koo
Adipocytes account for the largest proportion among the cells that comprise breast tissue; therefore, they are considered to be a critical cell type in the tumor microenvironment of breast cancer. In breast cancer, adipocytes are not only found adjacent to cancer cells, but they also play an active role in the entire process of cancer development, progression, metastasis, and treatment response. Factors including the secretion of adipokines such as leptin and adiponectin, as well as autotaxin, interleukin 6, tumor necrosis factor alpha, and hepatic growth factor, metabolic remodeling that supports the growth of breast cancer by transfer of fatty acids to increase mitochondrial β-oxidation, extracellular matrix remodeling and endotrophin production from type IV collagen, and cancer-associated fibroblast phenotype changes have all been implicated in this comprehensive process...

The change of gut microbiome is associated with a serious of metabolic disorders, such as diabetes. As a glucagon-like peptide 1 analogue, liraglutide is a potent antidiabetic drug in clinical practice. However, the effect of liraglutide on the community of gut microbiota is still unknown. We aimed to determine the influence of liraglutide on fecal microbiota in diabetic male rats. Five-week-old male Sprague-Dawley rats were fed with a control diet or a high-fat diet for four weeks. By injecting streptozotocin, the diabetic rat model was performed...

True seals have the shortest lactation periods of any group of placental mammal. Most are capital breeders that undergo short, intense lactations, during which they fast while transferring substantial proportions of their body reserves to their pups, which they then abruptly wean. Milk was collected from Atlantic grey seals (Halichoerus grypus) periodically from birth until near weaning. Milk protein profiles matured within 24 hours or less, indicating the most rapid transition from colostrum to mature phase lactation yet observed...

Apolipoprotein E (APOE) has been strongly implicated in the development of diet induced obesity. In the present study, we investigated the contribution of brain and peripherally expressed human apolipoprotein E3 (APOE3), the most common human isoform, to diet induced obesity. In our studies APOE3 knock-in (Apoe3(knock-in)), Apoe-deficient (apoe(-/-)) and brain-specific expressing APOE3 (Apoe3(brain)) mice were fed western-type diet for 12week and biochemical analyses were performed. Moreover, AAV-mediated gene transfer of APOE3 to apoe(-/-) mice was employed, as a means to achieve APOE3 expression selectively in periphery, since peripherally expressed APOE does not cross blood brain barrier (BBB) or blood-cerebrospinal fluid barrier (BCSFB)...

BACKGROUND: Brown adipose tissue (BAT) has a great relevance in metabolic diseases and has been shown to be reduced in obesity and insulin resistance patients. Currently, Dixon MRI is used to calculate fat-water fraction (FWF) and differentiate BAT from white adipose tissue (WAT). However, it may fail in areas of phase wrapping and introduce fat-water swapping artifacts. PURPOSE: To investigate the capacity of the Z-spectrum imaging (ZSI) for the identification of BAT in vivo...

Yarrowia lipolytica is a suitable microbial platform to convert low-value hydrophobic substrates into microbial oils and other important metabolites. In this work, this yeast species was used to simultaneously synthetize ex novo lipids and produce citric acid and lipase from animal fat (pork lard) adding higher value to the low-cost fatty substrate. The effect of pH, lard concentration, arabic gum concentration and oxygen mass transfer rate (OTR) on lipids accumulation on Y. lipolytica batch cultures was assessed by an experimental design based on Taguchi method...

Adipose-derived stem cells (ADSCs) play critical roles in controlling obesity-associated inflammation and metabolic disorders. Exosomes from ADSCs exert protective effects in several diseases, but their roles in obesity and related pathological conditions remain unclear. Here we showed that treatment of obese mice with ADSC-derived exosomes facilitated their metabolic homeostasis including improved insulin sensitivity (27.8% improvement), reduced obesity and alleviated hepatic steatosis. ADSC-derived exosomes drove M2 macrophage polarization, inflammation reduction and beiging in white adipose tissues (WAT) of diet-induced obese mice...

OBJECTIVE: Gene therapy that expresses apo A-I (apolipoprotein A-I) from vascular wall cells has promise for preventing and reversing atherosclerosis. Previously, we reported that transduction of carotid artery endothelial cells with a helper-dependent adenoviral (HDAd) vector expressing apo A-I reduced early (4 weeks) fatty streak development in fat-fed rabbits. Here, we tested whether the same HDAd could provide long-term protection against development of more complex lesions. APPROACH AND RESULTS: Fat-fed rabbits (n=25) underwent bilateral carotid artery gene transfer, with their left and right common carotids randomized to receive either a control vector (HDAdNull) or an apo A-I-expressing vector (HDAdApoAI)...

Consumption of a typical Western diet is a risk factor for several disorders. Metabolic syndrome is the most common disease associated with intake of excess fat. However, the incidence of inflammatory bowel disease is also greater in subjects consuming a Western diet, although the mechanism of this phenomenon is not clearly understood. We examined the morphological and functional changes of the intestine, the first site contacting dietary fat, in mice fed a high-fat diet (HFD) inducing obesity. Paneth cell area and production of antimicrobial peptides by Paneth cells were decreased in HFD-fed mice...

Today's demographic of the breast reconstruction patient is younger, often prophylactic or at an early stage of diagnosis, and is more likely to be bilateral. These factors combined with an increase in breast implant options, internal support matrices, fat transfer, technologies for intraoperative real time assessment of tissue perfusion, and an increasing appreciation for morbidity associated with autogenous procedures have resulted in an increase in the percentage of women seeking alloplastic breast reconstruction...

The treatment of sequelae after conservative breast cancer treatment can be a challenge. Lipomodeling, although controversial in the beginning, is a safe technique that can help in the treatment of these deformities, without an important impact on the imaging surveillance. Depending on the severity of the deformity, one or several sessions of fat transfer can be required. The technique is easy and reproducible, but before obtaining satisfying results with a low complication rate, a learning curve should be completed...

>Background: Temporal hollowing is inevitable after decompressive craniectomy. This complication affects self- perception and quality of life, and various techniques and materials have therefore been used to restore patients' confidence. Autologous fat grafting in postoperative scar tissue has been considered challenging because of the hostile tissue environment. However, in this study, we demonstrate that autologous fat grafting can be a simple and safe treatment of choice, even for postoperative depressed temporal scar tissue...

Obesity, the excessive accumulation of lipids in the body, is closely associated with many prevalent human disorders. Continued efforts to identify plant extracts that exhibit anti-obesity effects have drawn much attention. This study investigated whether a Polygala tenuifolia extract (PTE) possesses anti-obesity activity and how PTE may affect liver gene expression and gut microbiota. We used 3T3-L1 adipocytes and a high-fat diet-induced obese mouse model to determine the effects of PTE on lipid accumulation...
