N-terminal propeptide of type I procollagen and C-terminal telopeptide of type I collagen are the reference standards for bone turnover markers for monitoring osteoporosis treatment. We provide recommendations for standardized sample handling and encompassing aspects of preanalytical variability to improve the reproductibility of their measurements, their reliability, and clinical interpretation. The International Osteoporosis Foundation and International Federation of Clinical Chemistry bone turnover marker standards working group have identified N-terminal propeptide of type I procollagen (PINP) and C-terminal telopeptide of type I collagen (CTX-I) in the blood to be the international reference standards for bone turnover markers for the prediction of fracture risk and monitoring of osteoporosis treatment...

There is a lack of information concerning the molecular events underlying the depressive-like effect of an intracerebroventricular injection of streptozotocin (ICV-STZ) in mice. The elevated activity of the tryptophan-degrading enzyme indoleamine-2,3-dioxygenase (IDO) has been proposed to mediate depression in inflammatory disorders. In the present study, we reported that ICV-STZ activates IDO in the hippocampus of mice and culminates in depressive-like behaviors, as measured by the increased duration of immobility in the tail suspension test and decreased sucrose intake in the sucrose preference test...

We have previously demonstrated that maternal exposure to glyphosate-based herbicide (GBH) leads to glutamate excitotoxicity in 15-day-old rat hippocampus. The present study was conducted in order to investigate the effects of subchronic exposure to GBH on some neurochemical and behavioral parameters in immature and adult offspring. Rats were exposed to 1% GBH in drinking water (corresponding to 0.36% of glyphosate) from gestational day 5 until postnatal day (PND)-15 or PND60. Results showed that GBH exposure during both prenatal and postnatal periods causes oxidative stress, affects cholinergic and glutamatergic neurotransmission in offspring hippocampus from immature and adult rats...

Patients with overgrowth and complex vascular malformation syndromes, including Proteus syndrome have an increased risk of thromboembolism. Proteus syndrome is a mosaic, progressive overgrowth disorder involving vasculature, skin, and skeleton, and caused by a somatic activating mutation in AKT1. We conducted a comprehensive review of the medical histories and hematologic evaluations of 57 patients with Proteus syndrome to identify potential risk factors for thrombosis. We found that six of ten patients, who were deceased, died secondary to deep venous thrombosis and/or pulmonary embolism...

Glyoxalase 1 (Glo1) is the first enzyme involved in glutathione-dependent detoxification of methylglyoxal, eventually generating d-lactate by the second enzyme glyoxalase 2 (Glo2). An accumulation of intracellular glyoxal and methylglyoxal leads to protein malfunction and mutation via formation of the advanced glycation end products (AGEs). Studies on mouse behavior suggest that methylglyoxal has anxiolytic properties. In this report, we generated and characterized a mouse knockout for Glo1. The knockout mice were viable without a pronounced phenotypic defect...

Shortly after spinal cord injury (SCI), the musculoskeletal system undergoes detrimental changes in size and composition, predominantly below the level of injury. The loss of muscle size and strength, along with increased immobility, predisposes persons with SCI to rapid and severe loss in bone mineral density and other health related consequences. Previous studies have highlighted the significance of measuring thigh muscle cross-sectional area, however, measuring the size and composition of muscles of the lower leg may provide insights on how to decrease the risk of various comorbidities...

BACKGROUND: Indeed, intracerebral hemorrhage (ICH) account for only 15% of all strokes but it is one of the most devastating subtype of stroke associated with behavioral, cognitive and neurological deficits. The primary cause of neurological deficits in ICH is the hematoma growth, generation of free radicals, inflammatory cytokines and exhausting endogenous anti-oxidant machinery. It has been found that neuroinflammation following ICH leads to exaggeration of hallmarks of ICH. With this background, the study was aimed to evaluate the protective effect of resveratrol (RSV) in intracerebroventricular (ICV) collagenase (COL) induced neurological deficits in rats...

Resolvin D1 (RvD1) and D2 (RvD2) are lipid mediators that are derived from docosahexaenoic acid. We recently demonstrated that intracerebroventricular (i.c.v.) infusions of RvD1 or RvD2 attenuate lipopolysaccharide-induced depression-like behaviors via mammalian target of rapamycin complex 1 signaling. However, the antidepressant effects of RvD1 and RvD2 have not been fully investigated. Here, we examined the antidepressant effects of RvD1 and RvD2 using the tail suspension test (TST) and forced swim test (FST) in murine chronic unpredictable stress (CUS) model...

Neonatal administration of clomipramine (CMI) induces diverse behavioral and neurochemical alterations in adult male rats that resemble major depression disorder. However, the possible behavioral alterations in adult female rats subjected to neonatal treatment with clomipramine are unknown. Therefore, the aim of this study was to explore the effect of neonatal treatment with CMI on adult female rats in relation to locomotion and behavioral despair during the estrus cycle. Also evaluated was the effect of chronic treatment with E2 on these female CMI rats...

Post-traumatic stress disorder (PTSD) is characterized by memory disturbances following trauma. Acute predator threat has emerged as an ethological model of PTSD, yet the effects of predator odor on signaling cascades associated with long-term memory remain poorly understood. In this study, we exposed male and female Wistar rats to the synthetic predator odor 2,5-dihydro-2,4,5-trimethylthiazoline (TMT) to assess behavioral and physiological responses as well as rapid modulation of signal transduction cascades associated with learning and memory in the male and female hippocampus...

Pain flare is a well-recognized side-effect of palliative radiotherapy for the treatment of painful bone metastases, with recent randomized data showing incidence rates up to 35%. The impact of pain flare has been associated with worsening immobility, anxiety, depression and quality of life. The use of dexamethasone has recently been supported as an effective option in reducing radiation-induced pain flare based on the NCIC Clinical Trials Group (NCIC CTG) Symptom Control 23 (SC.23) randomized double-blind placebo-controlled trial...

Background: Stress constitutes a risk factor across several psychiatric disorders. Moreover, females are more susceptible to stress-related disorders, such as depression, than males. Although dopamine (DA) system underactivation is implicated in the pathophysiology of depression, little is known about the female DA system at baseline and post-stress. Methods: The effects of chronic mild stress (CMS) were examined on ventral tegmental area (VTA) DA neuron activity and forced swim test (FST) immobility by comparing male and female rats...

Active resistance is considered to be the "normal" reaction during rape. However, studies have indicated that similar to animals, humans exposed to extreme threat may react with a state of involuntary, temporary motor inhibition known as tonic immobility. The aim of the present study was to assess the occurrence of tonic immobility during rape and subsequent posttraumatic stress disorder and severe depression MATERIAL AND METHODS: Tonic immobility at the time of the assault was assessed using the Tonic Immobility Scale in 298 women who had visited the Emergency clinic for raped women within 1 month of a sexual assault...

In the present study, the effects of both single (6 mmol L-serine/10 ml/kg orally administrated) and chronic (2% L-serine solution freely given for 28 days) treatments on depression-like behavior were evaluated in Wistar rats, representing the control, and Wistar Kyoto rats, representing an animal model of depression. Both single and chronic L-serine treatments decreased the duration of immobility, which is an index of a depressive-like state, in the forced swimming test in both strains. However, the decreases in the duration of immobility appear to be regulated differently by the different mechanisms involved in single and chronic L-serine treatments...
