Depressive symptoms are reported by more than 20% of people with inflammatory bowel disease (IBD), whilst sleep difficulties and fatigue are even more common. Comorbid depressive symptoms predict a poor IBD course, including increased risk of relapse and surgery, which is inconsistently improved by psychological treatments. Rather than being distinct systems, there is compelling evidence for bidirectional communication between gut and brain, driven by neural, metabolic, endocrine and inflammatory mediators...

Benign prostatic hyperplasia (BPH) patients experience complications after surgery. We studied oxidative stress scavenging by porous Se@SiO2 nanospheres in prostatic urethra wound healing after transurethral resection of the prostate (TURP). Beagle dogs were randomly distributed into two groups after establishing TURP models. Wound recovery and oxidative stress levels were evaluated. Re-epithelialization and the macrophage distribution at the wound site were assessed by histology. The mechanism by which porous Se@SiO2 nanospheres regulated macrophage polarization was investigated by qRT-PCR, western blotting, flow cytometry, immunofluorescence and dual luciferase reporter gene assays...

OBJECTIVES: Dieting often fails because weight loss triggers strong counter-regulatory biological responses such as increased hunger and hypometabolism that are thought to be critically dependent on the master fuel sensor in the mediobasal hypothalamus (MBH). Because prolonged starvation has been shown to increase AgRP and NPY, the expression level of these two orexigenic genes has been taken as an experimental readout for the presence or absence of hunger. Roux-en-Y gastric bypass (RYGB) surgery leads to a significant weight loss without inducing the associated hunger, indicating possible changes in hypothalamic neuropeptides and/or signaling...

Reduced blood flow in the skin is observed in patients with neuropathic pain and in animal models. The aim of the present study was to elucidate the relationship between reduced skin blood flow and neuropathic pain in mice with a chronic constriction injury (CCI). Noradrenaline-induced contraction was enhanced in isolated plantar arteries ipsilateral to the CCI surgery compared to the contralateral arteries. Ten μM hydralazine, a peripheral vasodilator, at improved the enhanced contractile response in the ipsilateral arteries...

Previous studies have compared the effects of different interbody fusion approaches on biomechanical responses of the lumbar spine to static loadings. However, very few have dealt with the whole body vibration (WBV) condition that is typically present in vehicles. This study was designed to determine the biomechanical differences among anterior, posterior and transforaminal lumbar interbody fusion (ALIF, PLIF and TLIF) under vertical WBV. A previously developed and validated finite element (FE) model of the intact L1-sacrum human lumbar spine was modified to simulate ALIF, PLIF and TLIF with bilateral pedicle screw fixation at L4-L5...

Many aspects of the laboratory environment are not tailored to the needs of rodents, which may cause stress. Unpredictable stressors can cause ulcers, prolonged pituitary-adrenal activation, and anhedonia. Similarly, pain has been demonstrated to slow wound healing, and mice experiencing pain exhibit altered behavior. However it is unknown how husbandry, which occurs when the mice are inactive, and lack of analgesia, specifically in a punch biopsy procedure, effects animal physiology, behavior, and welfare, particularly as it relates to sleep fragmentation...

Ischemic stroke is the second most common cause of death, a major cause of acquired disability in adults. However, the pathogenesis that contributes to ischemic stroke has not been fully understood. Dual-specificity phosphatase 14 (DUSP14, also known as MKP6) is a MAP kinase phosphatase, playing important role in regulating various cellular processes, including oxidative stress and inflammation. However, its effects on cerebral ischemia/reperfusion (IR) are unclear. In the study, we found that DUSP14 expression was decreased responding to IR surgery...

BACKGROUND: Women with breast cancer (BCa) experience heightened distress, which is related to greater inflammation and poorer outcomes. The s100 protein family facilitates the inflammatory response by regulating myeloid cell function through the binding of Toll-like receptor 4 and the receptor for advanced glycation end products (RAGE). The heterodimer s100A8/A9 RAGE ligand is associated with hastened tumor development and metastasis. Previously, a 10-week stress-management intervention using cognitive behavioral therapy (CBT) and relaxation training (RT) was associated with less leukocyte inflammatory gene expression in patients with BCa; however, its impact on s100A8/A9 was not examined...

OBJECTIVE: Local anesthetic endovenous procedures were shown to reduce recovery time, to decrease postoperative pain, and to more quickly return the patient to baseline activities. However, a substantial number of patients experience pain during these procedures. The autonomic nervous system modulates pain perception, and its influence on stress response can be noninvasively quantified using heart rate variability (HRV) indices. The aim of our study was to evaluate whether preoperative baseline HRV can predict intraoperative pain during local anesthetic varicose vein surgery...

The biomechanical properties of the major pulmonary arteries play critical roles in normal physiology as well as in diverse pathophysiologies and clinical interventions. Importantly, advances in medical imaging enable simulations of pulmonary hemodynamics, but such models cannot reach their full potential until they are informed with region-specific material properties. In this paper, we present passive and active biaxial biomechanical data for the right and left main pulmonary arteries from wild-type mice...
