Umbilical cord-derived mesenchymal stem cells (UC-MSCs), with both immunomodulatory and pro-regenerative properties, are promising for the treatment of type 2 diabetes mellitus (T2DM). As efficient cell therapy largely relies on appropriate homing to target tissues, knowing where and to what extent injected UC-MSCs have homed is critically important. However, bio-distribution data for UC-MSCs in T2DM subjects are extremely limited. Beneficial effects of UC-MSCs on T2DM subjects are associated with increased M2 macrophages, but no systemic evaluation of M2 macrophages has been performed in T2DM individuals...

BACKGROUND: Low back pain (LBP) has been previously associated with delayed anticipatory postural adjustments (APAs) determined by trunk muscle activation. Lumbar stabilization exercise programs (LSEP) for patients with LBP may restore the trunk neuromuscular control of the lumbar spine, and normalize APAs. This exploratory study aimed at testing the reliability of EMG and kinematics-based postural adjustment measures over an 8-week interval, assessing their sensitivity to LBP status and treatment and examining their relationship with clinical outcomes...

Facilitated pain mechanisms have been demonstrated in musculoskeletal pain but it is unclear whether a recent painful injury leaves the pain system sensitized. Pain characteristics were assessed in individuals who recently recovered from ankle pain (recovered pain group; n=25) and sex-matched controls (n=25) in response to tonic-pressure pain and saline-induced pain applied at the shin muscle. Pain intensity and pain referral patterns were recorded bilaterally after the painful muscle stimulus. Pressure pain thresholds (PPTs) were measured at the lower legs and shoulder...

Vascular smooth muscle cells (VSMC) exhibit a dual role in progression and maintenance of arteriosclerosis. They are fundamental for plaque stability but also can drive plaque progression. During pathogenic vascular remodeling, VSMC transdifferentiate into a phenotype with enhanced proliferation and migration. Moreover, they exert an increased capacity to generate extracellular matrix proteins. A special lineage of transdifferentiated VSMC expresses Sox9, a multi-functional transcription factor. The aim of the study was to examine the role of Sox9 in phenotypic alterations leading to arteriosclerosis...

Cinnamaldehyde (Cin), as a traditional flavor constituent isolated from the bark of Cinnamonum cassia Presl, has been commonly used for - digestive, cardiovascular and immune system diseases. The pathology of vascular smooth muscle cells (VSMCs) accelerated the progression of atherosclerosis. In our study, we found that cinnamaldehyde significantly suppressed ox-LDL-induced VSMCs proliferation, migration and inflammatory cytokine overproduction, as well as foam cell formation in VSMCs and macrophages. Moreover, cinnamaldehyde inhibited the phosphorylation of p38, JNK and p65 NF-κB and increased heme oxygenase-1 (HO-1) activity...

OBJECTIVE: The anatomy of the perineum and the pelvic diaphragm of woman is complex. A numerical complete three-dimensional (3D) model of every muscle of the woman pelvis doesn't exist. The pathophysiology of genital prolapse is still debated. Knowledge of anatomy is essential to better understand its mechanisms. The aim of this research was to build a complete three-dimensional model of the female perineum and pelvic floor muscles. STUDY DESIGN: To model the pelvic muscles we reconstructed them in three dimensions from tracing a magnetic resonance imaging (MRI) of a female pelvis from a cadaver...

Homocysteine (Hcy) can induce atherosclerosis through the inflammatory response and DNA methylation disorder. Our recent study has reported a novel epigenetic modified gene related to atherosclerosis -SMAD7. To further understand the pathogenesis of atherosclerosis, the current study was designed to investigate an inflammatory role of Hcy in human umbilical vein smooth muscle cells (HUVSMCs) through interfering with SMAD7 methylation. Using MALDI-TOF MS, we found that Hcy increased DNA methylation levels of SMAD7 promoter in a dose and time-dependent manner in HUVSMCs...

To elicit the immune protective of vaccine against the highly contagious and pathogenic disease caused by spring viremia of carp virus (SVCV), a novel functionalized single-walled carbon nanotubes (SWCNTs) were applied as a delivery vehicle for DNA vaccine. In this study, we report a SWCNTs-DNA vaccine encoding matrix protein of SVCV which, when injected in the muscle at a dose of 10 μg SWCNTs-pcDNA-M vaccine, confers up to 51.3% protection against intraperitoneal challenge with SVCV. In addition, SWCNTs as a promising vehicle can enhance about 17...

In organ fibrosis, mechanical stress and transforming growth factor beta-1 (TGF-β1) promote differentiation into myofibroblast from mesenchymal cells, leading to extracellular matrix (ECM) remodeling or active synthesis, deposition or degradation of ECM components. A major component of ECM, type I collagen (col I) triple helical molecules assemble into fibrils or are denatured to gelatin without triple-helicity in remodeling. However, whether changes of ECM components in remodeling have influence on mesenchymal cell differentiation remains elusive...

INTRODUCTION: Due to a high prevalence of asthma and exercise-induced bronchoconstriction in elite athletes, there is a high use of beta2 -adrenoceptor agonists (beta2 -agonists) in the athletic population. While anabolic in rodents, no study has been able to detect hypertrophy in humans after chronic beta2 -agonist inhalation. METHODS: We investigated if inhaled beta2 -agonist, terbutaline, alters body composition and metabolic rate with and without concurrent exercise training in healthy young men...

One hundred years have passed since guanidine, a precursor compound of biguanides and thus of metformin, was found to have a glucose-lowering effect in live animals1 . In this historical study, C. K. Watanabe1 did not set out to identify glucose-lowering agents but rather to understand the mechanism underlying the development of tetany in animals that have undergone parathyroidectomy. Watanabe 1 concluded that guanidine is a pathogenic factor responsible for tetany because its administration in rabbits resulted in "tetany-like" muscle cramps associated with low blood glucose levels...

During neuromuscular monitoring, repeated electrical stimulation evokes muscle responses of increasing magnitude ('staircase phenomenon', SP). We aimed to evaluate whether SP affects time course and twitches' values of an acceleromyographic assessed neuromuscular block with or without previous tetanic stimulation. Fifty adult patients were randomized to receive a 50 Hz tetanic stimulus (S group) or not (C group) before monitor calibration. After 20 min of TOF ratio (TOFr) stimulation rocuronium was administered...

Bone fractures in older adults are often preceded by a loss of muscle mass and strength. Likewise, bone loss with prolonged bed rest, spinal cord injury, or with exposure to microgravity is also preceded by a rapid loss of muscle mass. Recent studies using animal models in the setting of hindlimb unloading or botulinum toxin (Botox) injection also reveal that muscle loss can induce bone loss. Moreover, muscle-derived factors such as irisin and leptin can inhibit bone loss with unloading, and knockout of catabolic factors in muscle such as the ubiquitin ligase Murf1 or the myokine myostatin can reduce osteoclastogenesis...

Anatomical variants of muscle are commonly encountered by surgeons and radiologists. The flexor carpi radialis brevis (FCRB) is an anomalous muscle in the distal forearm with an estimated prevalence of 2-8%. In the literature, there are a few case reports of symptomatic FCRB tenosynovitis without a concomitant tear, and treatment methods described include both conservative and surgical management. We present a case of one patient with radial sided wrist pain and a partial FCRB tear, which to our knowledge is the first case report of a symptomatic FCRB tear...

BACKGROUND/OBJECTIVES: Spendthrift vs. thrifty individuals expend more energy and experience greater weight loss during caloric restriction (CR). Adaptive mechanisms in skeletal muscle, adipose tissue, and on hormone level modulate energy expenditure (EE) during weight loss. Metabolic mechanisms underlying the variability in EE during CR are unclear. The present study explored whether during long-term CR (i) gene expression changes in skeletal muscle and adipose tissue relate with the individual EE response and weight loss, and (ii) altered catecholamine and FGF21-concentrations are associated with measures of metabolic adaptation...
