A method of lipolysis. The method comprises deforming a region of skin so that the region of skin protrudes from surrounding skin. One or more radio frequency (RF) electrodes are positioned on the protruding region of skin so as to generate an electrical current through adipose tissue in the protruding region of skin when a voltage is applied to the electrode or electrodes. A voltage is then applied to the electrode or electrodes so as to deliver sufficient RF energy to the protruding region of skin to damage subcutaneous adipose tissue. The method of the invention may be used, for example, to achieve a reduction in body weight, cellulite reduction, loose skin reduction, wrinkle treatment, body surface tightening, skin tightening, and collagen remodeling.

Described herein are cryolipolysis devices, systems, and methods for facilitating percutaneous access to a target blood vessel by performing cryolipolysis on subcutaneous adipose tissue obscuring the target blood vessel (e.g., a vessel used for hemodialysis treatment). Generally, the devices include a cooling member carrying a coolant that cools a selected portion of adipose tissue overlying the target blood vessel to reduce the selected portion of adipose tissue, thereby forming a depression in the adipose tissue and allowing the target blood vessel closer to the surface of the skin. In some variations, the cooling member is placed subcutaneously to directly cool the selected portion of adipose tissue. In other variations, the cooling member is placed external to the patient to indirectly cool the selected portion of adipose tissue through the skin.

Method and compositions are provided for treating or preventing a skin pathology or disorder associated with diabetes and/or aging, by topical administration of at least one agent capable of restoring an impaired physiological condition of the skin associated with said skin pathology or disorder. Examples of such agents include PKC modulating agents, various adipokines and insulin signaling related molecules. In particular, restoration of the subcutaneous adipose tissue can overcome many of the diabetic skin pathologies and aging skin disorders and conditions.

Dual-energy absorptiometry is used to estimate intramuscular adipose tissue metrics and display results, preferably as related to normative data. The process involves deriving x-ray measurements for respective pixel positions related to a two-dimensional projection image of a body slice containing intramuscular adipose tissue as well as subcutaneous adipose tissue, at least some of the measurements being dual-energy x-ray measurements, processing the measurements to derive estimates of metrics related to the intramuscular adipose tissue in the slice, and using the resulting estimates. Processing the measurements includes an algorithm which places boundaries of regions, e.g., a large region and a smaller region. The regions are combined in an equation that is highly correlated with intramuscular adipose tissue measured by quantitative computed tomography in order to estimate intramuscular adipose tissue.

The invention relates to a biomechanics modeling method for subcutaneous adipose tissues based on linear elasticity and superelasticity models. According to the biomechanics modeling method, the problems that an existing subcutaneous adipose tissue model is low in simulation accuracy and speed are solved. The biomechanics modeling method comprises the following steps: (1) establishing a geometric model, and dividing grids; (2) establishing a linear elasticity biomechanics model; (3) establishing a superelasticity biomechanics model; (4) carrying out finite element simulation on the superelasticity biomechanics model according to the step (1) and the step (2); (5) carrying out finite element calculation on the linear elasticity model; and (6) carrying out finite element simulation on a mixed linear elasticity and superelasticity model. By virtue of comparison on a simulation result and an experimental result, the accuracy of the biomechanics modeling method is verified. By virtue of comparison on simulation time of the single linear model and superelasticity model, high efficiency of a simulation algorithm of the mixed linear elasticity and superelasticity model is verified. The biomechanics modeling method is applied to the field of biomedical engineering.

The invention provides an automatic intra-abdominal muscle and fat image segmentation method, which is used for simultaneously segmenting abdominal muscle tissues, visceral fat tissues and subcutaneous fat tissues. The method mainly comprises the following steps of: classifying pixels of an abdominal image to obtain a preliminary pixel value change range of fat tissues, muscle tissues and a background part; Secondly, performing further segmentation on the basis of the pixel value change range of the muscle tissue to obtain an outer contour part and an inner contour part of the muscle respectively, and finishing the segmentation of the muscle tissue based on the parts. Finally, the adipose tissue segmented in the first step is divided into two parts by the muscle tissue, and the visceral adipose tissue is located in the muscle tissue. The subcutaneous adipose tissue is located outside the muscle tissue. Compared with the prior art, the method has the advantages that all sliced musculartissues and adipose tissues are segmented at a time, the correct rate is high, and full-automatic segmentation is achieved.

The invention discloses a human sebum thickness measuring instrument capable of controlling ultrasonic waves through pressure, and belongs to the field of human physiological signal measurement. The pressure sensor and the ultrasonic probe simultaneously act on the human skin surface; the pressure sensor measures the pressure applied by the ultrasonic probe to the measured part of the human body;the signals are sent to an analog-to-digital converter of a single-chip microcomputer through an operational amplifier circuit; the single-chip microcomputer judges that pressure reaches threshold value, a high-voltage excitation circuit excites the ultrasonic probe to emit ultrasonic waves; the ultrasonic waves pass through human body subcutaneous adipose tissue and then return echo signals; echosignals are amplified by an amplifying circuit and then enter the single-chip microcomputer; the single-chip microcomputer calculates the average walking time of the ultrasonic waves in the human body fat tissue; and the thickness of the human body subcutaneous fat is obtained by multiplying the propagation speed of the ultrasonic waves in the human body fat tissue, and the measured thickness ofthe human body subcutaneous fat is displayed on the display module.

Disclosed is a transdermal composition, which uses high-purity phosphatidylcholine that is most susceptible to oxidation and the like, and which exhibits high stability and high migration into the skin. Specifically, a transdermal composition having good stability and migration into the skin is able to be obtained by preparing a transdermal composition (a colloidal dispersion liquid of phosphatidylcholine) that contains high-purity phosphatidylcholine, carnitine, a polyhydric alcohol and water. Since the transdermal composition does not contain an oleaginous base (an oil component), the transdermal composition has skin compatibility and is thus useful as a therapeutic agent or a cosmetic preparation. In addition, phosphatidylcholine and carnitine have an effect of achieving good migration into the skin and are capable of promoting systemic or local lipid metabolism in subcutaneous adipose tissues. Consequently, the transdermal composition is able to provide a transdermal preparation that is capable of promoting lipolysis in subcutaneous adipose tissues.

Embodiments of the present disclosure are directed to methods of inducing therapeutic adipose tissue inflammation using high frequency pressure waves (e.g. high frequency shockwaves) wherein the inflammation results in a reduction in the volume of subcutaneous adipose tissue. Embodiments include applying electrohydraulic generated shockwaves at a rate of between 10 Hz and 100 Hz to reduce the appearance of cellulite or the volume of subcutaneous fat in a treatment area.

Pathological regional adipose tissue accumulation associated with HIV-associated dysmorphic/dysmetabolic syndrome (HADDS) which may occur with or without subcutaneous adipose tissue lipodystrophy (and which is also described as HIV-associated adipose redistribution syndrome or HARS and other specific medical terms), is treated by administering an effective amount of human growth hormone or other substance which binds to and initiates signalling of the hGH receptor. Alternatively, a substance which stimulates production of endogenous hGH, such as human growth hormone releasing hormone, may be administered. HADDS and related syndromes include abnormal adipose tissue accumulation in the visceral, submandibular, supraclavicular, pectoral, mammary and/or dorsocervical (buffalo hump) area, and/or with subcutaneous lipomas, with or without associated metabolic or other physiologic abnormalities.
