Analysis of fetal adipose tissue volumes may provide useful insight towards assessment of overall fetal health, especially in cases with abnormal fetal growth. Here, we assess whether fetal adipose tissue volume can be reliably measured using 3D water-fat MRI, using a quantitative assessment of the lipid content of tissues. Seventeen women with singleton pregnancies underwent a fetal MRI and water-only and fat-only images were acquired (modified 2-point Dixon technique). Water and fat images were used to generate a fat signal fraction (fat/(water + fat)) from which subcutaneous adipose tissue was segmented along the fetal trunk. Inter-rater (three readers) and intrarater reliability was assessed using intraclass-correlation coefficients (ICC) for 10 image sets. Relationships between adipose tissue measurements and gestational age and estimated fetal weight percentiles were examined. The ICC of the inter-rater reliability was 0.936 ( < .001), and the ICC of the intrarater reliability was 0.992 ( < .001). Strong positive correlations were found between adipose tissue measurements (lipid volume, lipid volume/total fetal volume, mean fat signal fraction) and gestational age. 3D water-fat MRI can reliably measure volume and quantify lipid content of fetal subcutaneous adipose tissues.

Impact of adipocytes on ultrasound evaluation of parathyroid adenomas.

Department of Internal Medicine, Kuma Hospital, Kobe, Hyogo, 650-0011, Japan.
Purpose: Parathyroid lipoadenomas are difficult to recognize preoperatively; hence, they may remain undetected. Difficulty in recognition is thought to be due to the adipocytes present in the tumor. This study aimed to clarify the impact of adipocytes as a component of parathyroid adenomas on ultrasound evaluation.

Background: Hypertrophic scar (HS) is a fibroproliferative disorder resulting from abnormal healing of skin tissue after injury. Although various therapies are currently employed in clinical to treat HSs, there is no widely accepted standard therapy. Micro-plasma radiofrequency (MPR) and autologous chyle fat grafting are emerging treatments for this condition, and they have demonstrated promising therapeutic outcomes in clinical applications.

Background: INTER- and INTRAmuscular fat (IMF) is elevated in high metabolic states and can promote inflammation. While magnetic resonance imaging (MRI) excels in depicting IMF, the lack of reproducible tools prevents the ability to measure change and track intervention success.
Methods: We detail an open-source fully-automated iterative threshold-seeking algorithm (ITSA) for segmenting IMF from T1-weighted MRI of the calf and thigh within three cohorts (CaMos Hamilton (N = 54), AMBERS (N = 280), OAI (N = 105)) selecting adults 45-85 years of age.

Virology Department, Croatian Veterinary Institute, Zagreb, Croatia.
Background: Canine adipose-derived mesenchymal stem cells (cAD-MSCs) demonstrate promising tissue repair and regeneration capabilities. However, the procurement and preservation of these cells or their secreted factors for therapeutic applications pose a risk of viral contamination, and the consequences for cAD-MSCs remain unexplored. Consequently, this research sought to assess the impact of canid alphaherpesvirus 1 (CHV) on the functional attributes of cAD-MSCs, including gene expression profiles and secretome composition.

ORTHOREBIRTH Co., Ltd., Yokohama, Japan.
Background: A biodegradable nonwoven fabric that can be used to extract adipose-derived stem cells (ADSCs) from adipose tissue slices was developed, which were cultured rapidly without enzymatic treatment. The extracted and cultured ADSCs remain on the nonwoven fabric and form a thick cell sheet. The aim was to use the thick cell sheet as a treatment by transplanting it into the living body.
