Colony stimulating factor-1 (CSF-1) is one of the most common proinflammatory cytokine responsible for various inflammatory disorders. It has a remarkable role in the development and progression of osteoarthritis, cancer and other autoimmune disease conditions. The CSF-1 acts by binding to the receptor, called colony stimulating factor-1 receptor (CSF-1R) also known as c-FMS resulting in the cascade of signalling pathway causing cell proliferation and differentiation. Interleukin-34 (IL-34), recently identified as another ligand for CSF-IR, is a cytokine protein...

Urine patches and dung pats from grazing livestock create hotspots for production and emission of the greenhouse gas, nitrous oxide (N2 O), and represent a large proportion of total N2 O emissions in many national agricultural greenhouse gas inventories. As such, there is much interest in developing country specific N2 O emission factors (EFs) for excretal nitrogen (EF3, pasture, range and paddock) deposited during gazing. The aims of this study were to generate separate N2 O emissions data for cattle derived urine and dung, to provide an evidence base for the generation of a country specific EF for the UK from this nitrogen source...

BACKGROUND: Endocrine treatment (ET) with an aromatase inhibitor (AI) is the treatment of choice in post-menopausal patients with hormone receptor-positive early breast cancer (EBC). However, adverse events (AEs) often lead to treatment discontinuation. This analysis aimed to identify side-effects that lead to patients failing to persist with letrozole treatment. PATIENTS AND METHODS: Post-menopausal hormone receptor-positive EBC patients starting ET with letrozole were enroled in EvAluate-TM, a non-interventional study...

Little is known about the role of long non-coding RNA XIST in the development of colon cancer. The aim of the present study was to investigate the levels of XIST in colon cancer, and explore its underlying mechanism. In this study, we found XIST expression level was upregulated in colon cancer tissues and cell lines. In addition, the growth rate of cells transfected with si-XIST was significantly decreased compared to that with si-NC, which was reversed by miR-34a targeted with 3'-UTR. Moreover, miR-34a suppressed the expression of WNT1 by binding with the 3'-UTR, which interact with WNT1 to inhibit the proliferation of cells...

Bone loss associated with estrogen deficiency occurs due to a high level of bone remodelling, with a greater increase in the level of osteoclast-mediated bone resorption than osteoblast-mediated bone formation. Early studies showed that Interleukin-6 (IL-6) inhibition could prevent the increase in osteoclast numbers associated with ovariectomy. However, IL-6 signals through two possible pathways: classic IL-6 signalling (cis) utilizes a membrane-bound IL-6 receptor (IL-6R), while IL-6 trans-signalling occurs through a soluble IL-6R (sIL-6R)...

Rhabdomyolysis is one of the serious side effects of ciprofloxacin (CPFX), a widely used antibacterial drug; and occasionally, acute kidney injury (AKI) occurs. Often, rhabdomyolysis has occurred in patients taking CPFX co-administered with statins. The purpose of this study is to establish a mouse model of drug-induced rhabdomyolysis by co-administration of CPFX and atorvastatin (ATV) and to clarify the mechanisms of its pathogenesis. C57BL/6J mice treated with L-buthionine-(S,R)-sulfoximine (BSO), a glutathione synthesis inhibitor, were orally administered with CPFX and ATV for 4 days...

AIMS: PMNs (polymorphonuclear neutrophil) play important roles in early stage of inflammation induced ARDS (Acute Respiratory Distress Syndrome). Both HBP (Heparin-Binding Protein) released from active PMNs and β2 integrins on the surface of PMNs are involved in vascular leakage. The role and relationship of HBP and β2 integrins on ARDS still requires study. MATERIALS AND METHODS: We established ARDS model using C57BL/6 mice with cecal ligation and puncture and eliminating HBP and β2 integrin with respective antibodies...

Opioid-induced respiratory depression is a major obstacle to improving the clinical management of moderate to severe chronic pain. Opioids inhibit neuronal activity via various pathways, including calcium channels, adenylyl cyclase, and potassium channels. Currently, the underlying molecular pathway of opioid-induced respiratory depression is only partially understood. This study aimed to investigate the mechanisms of opioid-induced respiratory depression in vivo by examining the effects of different pharmacological agents on fentanyl-induced respiratory depression...

Alcohol during brain development leads to the widespread neuronal death observed in fetal alcohol spectrum disorders (FASD). In comparison, the mature brain is less vulnerable to alcohol. Studies into maturation-acquired alcohol resistance uncovered a protective mechanism that reduces alcohol-induced neuronal death through nitric oxide-cGMP-cyclic GMP-dependent protein kinase (NO-cGMP-cGK) signaling. However, the downstream processes underlying this neuroprotection remain unclear. Alcohol can disrupt levels of intracellular calcium ([Ca2+ ]i ) in vulnerable neuronal populations to trigger cell death in both in vivo and in vitro models of FASD...

Selective serotonin-reuptake inhibitors (SSRIs) are the most commonly prescribed antidepressants during pregnancy. The human placenta is a highly specialized organ supporting normal growth and development of the fetus. Therefore, this study aims to analyze the effects of SSRIs on villous cytotrophoblasts cells, using BeWo cells and human placental trophoblast cells in primary culture. The SSRIs fluoxetine and its metabolite norfluoxetine, sertraline and venlafaxine did not affect BeWo cell proliferation and viability, nor the percentage of M30-positive (apoptotic) primary trophoblast cells...

Angiogenesis after ischemic stroke contributes to the restoration of blood supply in the ischemic zone. Strategies to improve angiogenesis may facilitate the function recovery after stroke. Growing evidence shows that proteasome inhibitors enhance angioneurogenesis and induces a long-term neuroprotection after cerebral ischemia in rodents' models. We have previously reported that inhibition of the immunoproteasome subunit low molecular mass peptide 2 (LMP2) offers a strong neuroprotection in ischemic stroke rats...
