Transarterial chemoembolization (TACE) is an effective palliative intervention that is widely accepted for the management of hepatocellular carcinoma (HCC). Post-TACE pulmonary complications resulting in acute lung injury (ALI) or acute respiratory distress syndrome (ARDS) are rare events. Pulmonary complications after TACE are thought to be related to chemical injury subsequent to the migration of the infused ethiodized oil or chemotherapeutic agent to the lung vasculature, facilitated by arteriovenous (AV) shunts within the hyper-vascular HCC...

The aim of the present study was to investigate a method of laparoscopic nephron-sparing surgery (LNSS) for renal cell carcinoma (RCC) based on the precise anatomy of the nephron, and to decrease the incidence of hemorrhage and urinary leakage. Between January 2012 and December 2013, 31 patients who presented to the General Hospital of the People's Liberation Army (Beijing, China) were treated for RCC. The mean tumor size was 3.4±0.7 cm in diameter (range, 1.2-6.0 cm). During surgery, the renal artery was blocked, and subsequently, an incision in the renal capsule and renal cortex was performed, at 3-5 mm from the tumor edge...

Retroperitoneal lymphnode dissection (RPLND) is a fundamental surgical step in the treatment of testicular cancer. Nowadays primary RPLND has partially lost its role in favour of active surveillance (for low risk stage I disease) and short cycle chemotherapy in non-seminomatous germ cell tumour (NSGCT). Conversely, postchemotherapy-RPLND (PC-RPLND) remains the standard treatment for residual masses after chemotherapy. In consideration of curability rate of testicular cancer and the life expectancy of testicular cancer survivors the identification and the prevention of andrological complications became fundamental...

Critical limb ischemia (CLI) is one of the most severe forms of peripheral artery diseases, but current treatment strategies do not guarantee complete recovery of vascular blood flow or reduce the risk of mortality. Recently, human bone marrow derived mesenchymal stem cells (MSCs) have been reported to have a paracrine influence on angiogenesis in several ischemic diseases. However, little evidence is available regarding optimal cell doses and injection frequencies. Thus, the authors undertook this study to investigate the effects of cell dose and injection frequency on cell survival and paracrine effects...

Electrode materials based on conversion reactions with lithium ions generally show much higher energy density. One of the main challenges in the design of these electrode materials is to improve initial Coulombic efficiency and alleviate the volume changes during the lithiation-delithiation processes. Here, we achieve fully reversible conversion in MoO3 as an anode for lithium ion batteries by the hybridization of CoMoO4. The porous MoO3-CoMoO4 microspheres are constructed by homogeneously dispersed MoO3 and CoMoO4 subunits and their lithiation/delithiation processes were studied by ex-situ TEM to reveal the mechanism of the reversible conversion reaction...

BACKGROUND: Volume-targeted noninvasive ventilation (VT-NIV), a hybrid mode that delivers a preset target tidal volume (VT) through the automated adjustment of pressure support, could guarantee a relatively constant target VT over pressure-limited noninvasive ventilation (PL-NIV) with fixed-level pressure support. Whether VT-NIV is more effective in improving ventilatory status in subjects with acute hypercapnic respiratory failure (AHRF) remains unclear. Our aim was to verify whether, in comparison with PL-NIV, VT-NIV would be more effective in correcting hypercapnia, hence reducing the need for intubation and improving survival in subjects with AHRF...

Due to the significantly improved outcome and quality of life of patients with different tumor entities after cytoreductive surgery (CRS) and HIPEC, there is an increasing number of centers performing CRS and HIPEC procedures. As this procedure is technically challenging with potential high morbidity and mortality, respectively, institutional experience also in the anesthetic and intensive care departments is essential for optimal treatment and prevention of adverse events. Clinical pathways have to be developed to achieve also good results in more comorbid patients with border line indications and extensive surgical procedures...

Hypoxia, that is, insufficient oxygen partial pressure, is a known cause of reduced radiosensitivity in solid tumors, and especially in head-and-neck tumors. It is thus believed to adversely affect the outcome of fractionated radiotherapy. Oxygen partial pressure varies spatially and temporally over the treatment course and exhibits inter-patient and intra-tumor variation. Emerging advances in non-invasive functional imaging offer the future possibility of adapting radiotherapy plans to this uncertain spatiotemporal evolution of hypoxia over the treatment course...

BACKGROUND: Previous studies confirmed that classical scrapie can be transmitted via milk in sheep. The current study aimed to investigate whether scrapie can also be transmitted via goat milk using in vivo (new-born lambs fed milk from scrapie-affected goats due to the unavailability of goat kids from guaranteed scrapie-free herds) and in vitro methods (serial protein misfolding cyclic amplification [sPMCA] on milk samples). RESULTS: In an initial pilot study, new-born lambs of two different prion protein gene (PRNP) genotypes (six VRQ/VRQ and five ARQ/ARQ) were orally challenged with 5 g brain homogenate from two scrapie-affected goats to determine susceptibility of sheep to goat scrapie...

Microtiter plate (MTP) sealing tapes are commonly applied in bioprocess development and high throughput screening in order to maintain sterile conditions and avoid liquid evaporation. However, only a few of the commercially available sealing tapes are adequately characterised to guarantee both minimal evaporation and sufficient oxygen supply for aerobic cultivation. Therefore, 12 commercially available sealing tapes were analysed concerning their water vapour and oxygen permeability. The water vapour permeability was assessed by gravimetrically quantifying the liquid loss due to evaporation...

Barcodes-based suspension array have for demonstrated values in multiplex assay of tumor markers. Photonic barcodes which are encoded by their characteristic reflection peaks are the important supports for suspension array due to their stable code, low fluorescent background and high surface-volume ratio. Attempts to develop this technology tend to improve the function of the photonic barcodes. Here, we present a new type of hybrid hydrogel photonic barcodes for efficient multiplex assays. This photonic barcodes are hybrid inverse opal hydrogel composed of poly(ethylene glycol) diacrylate (PEG-DA) and agarose...

Epidemiology of Acute Kidney Injury (AKI) has changed radically in the past 15 years: we have observed an exponential increase of cases with high mortality and residual disability, particularly in those patients who need dialysis treatment. Those who survive AKI have an increased risk of requiring dialysis after hospital discharge over the short term as well as long term. They have an increased risk of deteriorating residual kidney function and cardiovascular events as well as a shorter life expectancy. Given the severe prognosis, difficulties of treatment, high level of resources needed, increased workload and consequently costs, several aspects of AKI have not been sufficiently investigated...
