BACKGROUND AND OBJECTIVE: Intracellular exposure of everolimus may be a better marker of therapeutic effect than trough whole blood concentrations. We aimed to develop pharmacokinetic population models and Bayesian estimators based on a limited sampling strategy for estimation of dose interval exposures of everolimus in whole blood and peripheral blood mononuclear cells (PBMCs) in renal transplant recipients. METHODS: Full whole blood and PBMC concentration-time profiles of everolimus were obtained from 12 stable renal transplant recipients on two different occasions, 4 weeks apart...

BACKGROUND: Renal transplant (RTX) recipients seem to experience a better quality of life compared to dialysis patients. However, the factors responsible for this positive effect are not completely defined. Conceivably, a change in the physical performance of these patients could play a role. METHODS: To assess this, we measured: (1) waist circumference, fat mass and appendicular fat-free mass (aFFM) by dual-energy X-ray densitometry, (2) physical performance with the Short Physical Performance Battery, and (3) muscle strength with the handgrip test, in 59 male RTX, 11 chronic kidney disease in conservative treatment (CKD) and 10 peritoneal dialysis (PD) patients...

The relationship between fat, bone and systemic metabolism is a growing area of scientific interest. Marrow adipose tissue is a well-recognized component of the bone marrow milieu and is metabolically distinct from current established subtypes of adipose tissue. Despite recent advances, the functional significance of marrow adipose tissue is still not clearly delineated. Bone and fat cells share a common mesenchymal stem cell (MSC) within the bone marrow, and hormones and transcription factors such as growth hormone, leptin, and peroxisomal proliferator-activated receptor γ influence MSC differentiation into osteoblasts or adipocytes...

MRI has transformed from the theoretical, investigative realm to mainstream clinical medicine over the past four decades and has become a core component of the diagnostic toolbox in the practice of gastroenterology (GI). Its success is attributable to exquisite contrast and the ability to isolate specific proton species through the use of different pulse sequences (i.e., T1-weighted, T2-weighted, diffusion-weighted) and exploiting extracellular and hepatobiliary contrast agents. Consequently, MRI has gained preeminence in various GI clinical applications: liver and pancreatic lesion evaluation and detection, liver transplantation evaluation, pancreatitis evaluation, Crohn's disease evaluation (using MR enterography) rectal cancer staging and perianal fistula evaluation...

OBJECTIVES: In kidney transplant recipients, reduced muscle mass and hand-grip strength are associated with impaired nutritional status. Serum testosterone is highly associated with muscle strength in the general population. Here, we aimed to determine the associations among serum testosterone, hand-grip strength, and nutritional and inflammatory parameters, as well as graft function. MATERIALS AND METHODS: Our study included 144 stable male kidney transplant recipients from our renal transplant outpatient clinic...

BACKGROUND: Scarring is the product of natural restoration, yet its treatment remains challenging. Both collagen and fibroblasts are abnormally abundant in scars, leading to scar hyperplasia or contracture. Several clinical studies have reported that wrinkles at the recipient site are reduced, pores are narrowed, pigmentation is decreased, and skin is softened after autologous fat transplantation. In this study, we investigated the ability of autologous chyle fat injection to normalize the fibroblasts and collagen of scar tissue in 80 adult patients with hypertrophic scars resulting from severe burns received more than 1 year previously...

Immunomodulatory activity of mesenchymal stem cells (MSCs) is largely mediated by paracrine factors. Our previous studies showed that activation of nuclear factor-kappa B (NF-κB) regulates cytokine/growth factor secretion by MSCs. This study aimed to elucidate the role of Rap1 (repressor/activator protein), a novel modulator involved in the NF-κB pathway, in regulating the immunomodulatory potency of MSCs in acute allograft rejection of heart transplantation. The immunosuppressive potency of wild-type MSCs (WT-MSCs) or Rap1-deficient MSCs (Rap1-/- -MSCs) was examined in mice with acute allograft rejection following heart transplantation...

Long-chain acyl-CoA synthetase (ACSL)-dependent upper small intestinal lipid metabolism activates pre-absorptive pathways to regulate metabolic homeostasis, but whether changes in the upper small intestinal microbiota alter specific fatty acid-dependent pathways to impact glucose homeostasis remains unknown. We here first find that upper small intestinal infusion of Intralipid, oleic acid, or linoleic acid pre-absorptively increases glucose tolerance and lowers glucose production in rodents. High-fat feeding impairs pre-absorptive fatty acid sensing and reduces upper small intestinal Lactobacillus gasseri levels and ACSL3 expression...

OBJECTIVE: To determine the accuracy of shear-wave elastography (SWE) to differentiate low from advanced degrees of liver fibrosis in hepatitis C patients. MATERIAL & METHOD: Consented native/transplant hepatitis C patients underwent SWE using a C1-6 MHz transducer before ultrasound (US)-guided liver biopsy. Five interpretable SWE samples were obtained from the right lobe of the liver immediately before US-guided random biopsy of the right lobe. Average kilopascal (kPa) values were compared to the meta-analysis of histological data in viral hepatitis (METAVIR) fibrosis grading...

Background: Fat grafting, or lipofilling, represent frequent clinically used entities. The fate of these transplants is still not predictable, whereas only few animal models are available for further research. Quantum dots (QDs) are semiconductor nanocrystals which can be conveniently tracked in vivo due to photoluminescence. Methods: Fat grafts in cluster form were labeled with cadmium-telluride (CdTe)-QD 770 and transplanted subcutaneously in a murine in vivo model...

The interplay of multipotent stromal cells derived from the orbital fat pads and cells of the lipoaspirate from the subcutaneous adipose tissue was studied using in vitro co-transplantation model in an organ culture in a collagen gel. Microscopy findings and intensity of apoptosis and cell proliferation in cultures of lipoaspirate with and without multipotent stromal cells showed that the cells maintained their viability, proliferation capacity, and cytokine secretion activity. Higher proliferatitive activity of cells in cocultures promotes renewal of fat transplant cells and can help to maintain its stable volume in delayed terms after transplantation...

BACKGROUND: The adipokine progranulin has metabolic proprieties, playing a role in obesity and insulin resistance. Its levels seems to be dependent of renal function, since higher progranulin concentration is observed in patients with end-stage kidney disease. However, the effect of kidney transplantation on progranulin remains unknown. OBJECTIVE: To assess the serum progranulin levels in kidney transplant recipients before and after kidney transplantation. METHODS: Forty-six prospective kidney transplant recipients were included in this longitudinal study...

Sarcopenia, the loss of muscle mass, has been identified as a potential risk factor for adverse outcomes in hematopoietic cell transplantation (HCT) recipients. However, much remains unknown about change in body composition following HCT. We retrospectively evaluated computed tomography (CT) imaging from 315 lymphoma patients undergoing HCT at our institution between 2000 and 2014. Cross-sectional area of lean muscle, subcutaneous adipose tissue and visceral adipose tissue were measured on CT at the level of the third lumbar vertebral body prior to HCT, 1-year post-HCT, and 2...

The research of carcinogenetic mechanisms of breast cancer in different ethnic backgrounds is an interesting field, as clinical features of breast cancers vary among races. High premenopausal incidence is distinctive in East-Asian breast cancer. However, human cell lines derived from Asian primary breast tumor are rare. To provide alternative cell line models with a relevant genetic background, we aimed to establish breast cancer cell lines from Taiwanese patients of Han-Chinese ethnicity. Fresh tissue from mammary tumors were digested into organoids, plated and grown in basal serum-free medium of human mammary epithelial cells (HuMEC) with supplements...

Background: Fat grafting technologies are popularly used in plastic and reconstructive surgery. Due to its size limitation, it is hard to directly inject untreated fat tissue into the dermal layer. Nanofat, which was introduced by Tonnard, solves this problem by mechanically emulsifying fat tissue. However, the viability of the cells was greatly destroyed. In this study, we reported a new method by "gently" digesting the fat tissue to produce viable adipocytes, progenitors, and stromal stem cells using collagenase I digestion and centrifugation...
