BACKGROUND: Ostructive sleep apnea (OSA) is an independent risk factor for the development of cardiovascular events. Platelet activation and inflammation are the mechanisms involved in the association between OSA and cardiovascular disease (CVD). The markers of platelet activation and inflammation are the mean platelet volume (MPV), platelet-lymphocyte ratio (PLR), red cell distribution width (RDW), neutrophil- lymphocyte ratio (NLR). We aimed to define the association of NLR, PLR, RDW, and MPV with the severity of disease and the presence of CVD...

Contusion injuries in skeletal muscle commonly occur in contact sport and vehicular and industrial workplace accidents. Icing has traditionally been used to treat such injuries under the premise that it alleviates pain, reduces tissue metabolism, and modifies vascular responses to decrease swelling. Previous research has examined the effects of icing on inflammation and microcirculatory dynamics following muscle injury. However, whether icing influences angiogenesis, collateral vessel growth, or myofiber regeneration remains unknown...

This investigation reports a simplified approach for the purification of urinary siderocalin known as neutrophil gelatinase-associated lipocalin (NGAL). Urinary NGAL was purified by tangential flow filtration and ion exchange chromatography. Isolated NGAL was analyzed by SDS-PAGE, immunoblotting and mass spectrometry (MS). The relative molecular mass of NGAL is 23674Da. Peptide mass fingerprinting of the purified NGAL yielded peptides that partially matched with known sequence of P80188 (NGAL_HUMAN). The tryptic digestion profile of isolated NGAL infers that it may be unique and additive molecule in the dictionary of urinary proteins...

Optimal timing of apheresis initiation is important for maximizing the hematopoietic stem cell (HSC) yield. This study aimed to identify useful parameters from automatic hematology analyzers for predicting the peripheral blood CD34+ cell count after mobilization. We prospectively enrolled 53 healthy donors and 72 patients, and evaluated 43 cell morphology parameters from Unicel DxH800 (Beckman Coulter, USA) and Advia 2120i (Siemens Healthcare Diagnostics, USA). The correlation of each parameter with the CD34+ cell count in pre-apheresis blood samples was analyzed...

BACKGROUND: Mean platelets volume (MPV) is a marker, which indicates platelet function, and is a potential link between inflammation and thrombosis. Previous studies have found a relation between high MPV levels and high risk of stroke. Another factor that has been associated with the risk of stroke is neutrophil to lymphocyte ratio (NLR). Several studies have reported an association between increased NLR and increased risk of cerebrovascular disease. It was found that NLR levels have a relation to the prognosis as well...

BACKGROUND: Uncemented orthopaedic implants rely on the bone-implant interface to provide stability, therefore it is essential that a coating does not interfere with the bone-forming processes occurring at the implant interface. In addition, local application of high concentrations of antibiotics for prophylaxis or treatment of infection may be toxic for osteoblasts and could impair bone growth. QUESTIONS/PURPOSES: In this animal study, we investigated the effect of a commercially available hydrogel, either unloaded or loaded with 2% vancomycin...

Hepatorenal syndrome (HRS) is a manifestation of extreme circulatory dysfunction and entails high morbidity and mortality. A new definition has been recently recommended by the International Club of Ascites, according to which HRS diagnosis relies in serum creatinine changes instead that on a fixed high value. Moreover, new data on urinary biomarkers has been recently published. In this sense, the use of urinary neutrophil gelatinase-associated lipocalin seems useful to identify patients with acute tubular necrosis and should be employed in the diagnostic algorithm...

BACKGROUND AND PURPOSE: Peripheral immune cell infiltration contributes to neural injury after ischemic stroke. However, in contrast to lymphocytes and neutrophils, the role of different monocyte/macrophage subsets remains to be clarified. Therefore, we evaluated the effects of selective and unselective monocyte/macrophage depletion and proinflammatory (M1-) and anti-inflammatory (M2-) macrophage transfer on the outcome after experimental cerebral ischemia. METHODS: To assess short-term effects of monocytes/macrophages in acute ischemic stroke, mice underwent transient middle cerebral artery occlusion and received either clodronate liposomes for unselective macrophage depletion, MC-21-antibody for selective depletion of proinflammatory Ly-6C(high) monocytes, or proinflammatory (M1-) or anti-inflammatory (M2-) macrophage transfer...

Inappropriate mechanical ventilation (MV) can result in ventilator-induced lung injury (VILI). Probing mechanisms of VILI and searching for effective methods are current areas of research focus on VILI. The present study aimed to probe into mechanisms of endothelial microparticles (EMPs) in VILI and the protective effects of Tetramethylpyrazine (TMP) against VILI. In this study, C57BL/6 and TLR4KO mouse MV models were used to explore the function of EMPs associated with p21 activated kinases-4 (PAK-4) in VILI...

The development of ventilator-induced lung injury (VILI) is still a major problem in mechanically ventilated patients. Low dose inhalation of hydrogen sulfide (H2S) during mechanical ventilation has been proven to prevent lung damage by limiting inflammatory responses in rodent models. However, the capacity of H2S to affect oxidative processes in VILI and its underlying molecular signaling pathways remains elusive. In the present study we show that ventilation with moderate tidal volumes of 12 ml/kg for 6 h led to an excessive formation of reactive oxygen species (ROS) in mice lungs which was prevented by supplemental inhalation of 80 parts per million of H2S...

BACKGROUND: Dengue fever (DF) and malaria are the two major public health concerns in tropical countries such as Thailand. Early differentiation between dengue and malaria could help clinicians to identify patients who should be closely monitored for signs of dengue hemorrhagic fever or severe malaria. This study aims to build knowledge on diagnostic markers that are used to discriminate between the infections, which frequently occur in malaria-endemic areas, such as the ones in Thailand...

Novel longer lasting inflammatory bladder animal models are needed to better understand the pathophysiology of chronic cystitis. We previously developed a relatively long-lasting mouse cystitis model by intravesical injection of hydrogen peroxide (H2O2). To further evaluate its pathophysiology, in this study, we established and analyzed a rat cystitis model. Under anesthesia, 1.5% H2O2 solution was introduced transurethrally into the bladder of female rats, and kept for 30 min. The H2O2 injection significantly increased the number of micturition events up to day 14 and decreased urine volume per micturition, with the smallest volumes on day 3, compared with the vehicle-treated group...
