It has been proposed that protein supplementation during resistance exercise training enhances muscle hypertrophy. The degree of hypertrophy during training is controlled in part through activation of satellite cells and myonuclear accretion. PURPOSE: To determine the efficacy of protein supplementation (and the type of protein) during traditional resistance training on myofiber cross-sectional-area, satellite cell content and myonuclear addition. METHODS: Healthy young men participated in supervised whole body progressive resistance training 3d/wk for 12 weeks...

Fibrous dysplasia (FD) is a benign bone lesion with a rare but potential for malignant transformation. Neither Tc-MDP nor F-FDG PET/CT can differentiate between FD and areas of malignant transformation in FD. We described a case of osteosarcoma developing in FD with selective uptake of tracer in malignant transformation areas demonstrated on a Ga-PSMA PET/CT scan. Our case highlights the ability of Ga-PSMA PET/CT to map tumor neoangiogenesis in osteosarcoma arising in FD, which can have potential implications in prognostication, possibility of antiangiogenesis-based therapeutic options, and in response assessment following chemotherapy...

Peptidoglycan fragments released from gut microbiota can be delivered to the bone marrow and affect bone metabolism. Here, we investigated the regulation of bone metabolism by muramyl dipeptide (MDP), which is a shared structural unit of peptidoglycans. Increased bone and mineral density by enhanced bone formation were observed in mice administered with MDP. Remarkably, pre-treatment or post-treatment with MDP alleviated bone loss in RANKL-induced osteoporosis mouse models. MDP directly augmented osteoblast differentiation and bone-forming gene expression by Runx2 activation...

Astringency is closely related to the interaction between procyanidins and salivary proteins (SP). The aim of this work was to study the interaction between mucin, a SP responsible for saliva lubricating properties, with different procyanidins (B4 dimer, tetramer (TT) and fractions of oligomeric procyanidins), and the influence of several conditions [pH, ionic strength, procyanidins' mean degree of polymerization (mDP) and different solvents (ethanol or dimethylsulfoxide)] on this interaction by fluorescence quenching and Saturation Transfer Difference (STD)-NMR...

We present a case of a 13 years old boy who was hospitalized with a 10 months history of progressive pain and weakness in his lower extremities. The laboratory tests revealed slightly decreased phosphate and 25-hydroxyvitamin D3, high alkaline phosphatase, normal calcium and parathyroid hormone (PTH). Magnetic resonance imaging (MRI) showed multiple patchy lesions indicating bone destruction in the metaphyses and epiphyses of the left knee. Fluorine-18-fluorodeoxyglucose positron emission tomography/computed tomography ((18)F-FDG PET/CT) revealed a generalized decrease of bone density in axial bones with slightly increased (18)F-FDG metabolism...

OBJECTIVE: Examination of major duodenal papilla (MDP) by standard forward-viewing esophagogastroduodenoscopy (S-EGD) is limited. Cap assisted esophagogastroduodenoscopy (CA-EGD) utilizes a cap fitted to the tip of the endoscope that can depress the mucosal folds and thus might improve visualization of MDP. The aim of this study was to compare CA-EGD to S-EGD for complete examination of the MDP. METHODS: Prospective, randomized, blinded, controlled crossover study...

BACKGROUND: Recent studies have demonstrated the intra-articular cartilage and labral damage that can occur from the proximal femoral cam-like deformity of a moderate to severe slipped capital femoral epiphysis (SCFE). The approach to treating this deformity in a symptomatic Loder stable hip is controversial. The purpose of this study was to compare radiographic outcomes, complication rates, and revision rates between Imhauser type triplane proximal femoral osteotomy (TPFO) and the modified Dunn procedure (MDP)...

An otherwise healthy 33-year-old man presents with new pain involving the right leg. Radiographs of the femur showed scattered lucent lesions. An MRI of the knee demonstrated nonspecific cortical-based lesions. Biopsy confirmed pseudomyogenic hemangioendothelioma. MDP bone scan and F-FDG PET/CT were obtained to evaluate for extent of disease demonstrating disease limited to the bone of the right leg. Interestingly, the FDG and MDP uptake and CT appearance of the disease were not entirely concordant, with some lesions being lytic on CT and associated with FDG and MDP uptake, other lesions being CT silent and either MDP or FDG avid...

Macrophages are important in host defense and can differentiate into functionally distinct subsets named classically (M1) or alternatively (M2) activated. In several inflammatory disorders, macrophages become tolerized to prevent deleterious consequences. This tolerization reduces the ability of macrophages to respond to bacterial components (e.g., LPS) maintaining a low level of inflammation but compromising the ability of macrophages to mount an effective immune response during subsequent pathogen encounters...

A 45-year-old man with a history of adenocarcinoma in the right lung 3 years ago underwent a Tc-MDP bone scan to evaluate possible osseous metastasis. The images demonstrated intense activity in the region of left thumb, while the tracer uptakes in other bones were not typical of metastases. A CT of the hand showed diffuse sclerotic changes with destructed trabecular structure in the proximal phalanx of the left thumb. The left thumb was subsequently resected, and the pathological examination of the resected left first metacarpal bone confirmed the diagnosis of metastasis of lung adenocarcinoma...

Network virtualization helps overcome shortcomings of the current Internet architecture. The virtualized network architecture enables coexistence of multiple virtual networks (VNs) on an existing physical infrastructure. VN embedding (VNE) problem, which deals with the embedding of VN components onto a physical network, is known to be NP-hard. In this paper, we propose two VNE algorithms: MaVEn-M and MaVEn-S. MaVEn-M employs the multicommodity flow algorithm for virtual link mapping while MaVEn-S uses the shortest-path algorithm...
