BACKGROUND: Pressurized intraperitoneal aerosol chemotherapy (PIPAC) has been recently reported as a new approach for intraperitoneal chemotherapy (IPC). By means of a patented micropump, the liquid chemotherapy is delivered into the peritoneal cavity as an aerosol which is supposed to achieve "gas-like" distribution. However, recent data report that the fraction of the submicron aerosol (gas-like) is less than 3 vol% of the total amount of aerosolized chemotherapy. Until today, possible modifications of treatment parameters during PIPAC with the aim of improving therapeutic outcomes have not been studied yet...

Ischemic heart disease have been remarked as a leading cause of morbidity and mortality in adults. Early restoration of cardiac perfusion is necessary to restore perfusion of ischemic heart muscle. Effective revascularization reduce mortality by limiting myocardial necrosis at the acute phase of the cardiac infarction. However, reperfusion may induce a cascade of pathophysiological reactions causing the increase of the infarct area of the myocardium This phenomenon known as ischemia-reperfusion injury is responsible for up to 50% of the final infarct size...

: 205 Background: Indwelling pleural catheter (IPC) placement is an alternative to chemical pleurodesis for malignant pleural effusion (MPE), a complication of advanced cancer. In 1997 an IPC was approved which uses vacuum bottles (VB) for drainage (PleurX, Becton, Dickinson and Company, Franklin Lakes, NJ), and later another IPC system, which employs a manually operated vacuum pump (VP) for drainage (Aspira, Bard Access Systems, Salt Lake City, UT). Most studies comparing IPC versus chemical pleurodesis used the VB IPC...

BACKGROUND: Systemic Lupus erythematosus (SLE), also commonly referred to as lupus, is a rare, but sometimes, fatal disease, that primarily affects young women. Lupus nephritis, a common manifestation of lupus, is more common and more devastating in patients of minority race/ethnicity. Patients have negative views of immunosuppressive drugs for lupus nephritis due to a concern about side effects and under-appreciation of its benefit. We designed a study to assess the effectiveness of individualized, computerized patient decision-aid for immunosuppressive drugs for lupus nephritis compared to a standard pamphlet for patient decision-making...

Decreased blood flow supply to the kidneys known as renal ischemia/reperfusion is a common occurrence during various clinical and surgical settings. This remains highly concerning as it is a major cause of acute kidney injury (AKI). The kidneys have a rich supply of efferent and afferent sympathetic nerves playing a crucial physiological role in regulation of renal function. Studies in animal models of renal ischemia/reperfusion injury have indicated that very early during an ischemic event, the sympathetic nerves are activated and in concert with decreased nitric oxide availability, increased angiotensin II and several other molecules results in renal damage...

Metal-free near-infrared (NIR) active unsymmetrical squaraine dyes, RSQ1 and RSQ2, with benzodithiophene (BDT) π-spacer and cyanoacrylic acid acceptor were synthesized by utilizing palladium catalyzed direct (hetero)arylation reaction. Methyl and 2-ethylhexyl groups were strategically placed at the BDT unit for RSQ1 and RSQ2, respectively, to investigate the effect of alkylated π-spacer on dye aggregation on the TiO2 surface and recombination reactions at TiO2/dye/electrolyte interface. These dyes have strong absorption (ε > 10(5) M(-1) cm(-1)) in near-infrared (NIR) region and exhibit similar optical and electrochemical properties as they have same conjugated framework...

Graphitic carbon nitride (g-C3N4) has been widely studied as a metal-free photocatalyst, leading to some excellent results; however, the rapid recombination of photogenerated charge carriers substantially limits its performance. Here, we establish two types of g-C3N4-based heterojunction (type II and nonmediator assisted Z-scheme) photoanodes on a transparent conducting substrate via coupling with rod-like and nanoparticulate WO3, respectively. In these composites, g-C3N4 film grown by electrophoretic deposition of exfoliated g-C3N4 serves as the host or guest material...

Exposure of the heart to 5 min global ischaemia (I) followed by 5 min reperfusion (R) (ischaemic preconditioning, IPC) or transient Beta 2-adrenergic receptor (B2-AR) stimulation with formoterol (B2PC), followed by 5 min washout before index ischaemia, elicits cardioprotection against subsequent sustained ischaemia. Since the washout period during preconditioning is essential for subsequent cardioprotection, the aim of this study was to investigate the involvement of protein kinase A (PKA), reactive oxygen species (ROS), extracellular signal-regulated kinase (ERK), PKB/Akt, p38 MAPK and c-jun N-terminal kinase (JNK) during this period...

Sublethal hypoxic or ischemic events can improve the tolerance of tissues, organs, and even organisms from subsequent lethal injury caused by hypoxia or ischemia. This phenomenon has been termed hypoxic or ischemic preconditioning (HPC or IPC) and is well established in the heart and the brain. This review aims to discuss HPC and IPC with respect to their historical development and advancements in our understanding of the neurochemical basis for their neuroprotective role. Through decades of collaborative research and studies of HPC and IPC in other organ systems, our understanding of HPC and IPC-induced neuroprotection has expanded to include: early- (phosphorylation targets, transporter regulation, interfering RNA) and late- (regulation of genes like EPO, VEGF, and iNOS) phase changes, regulators of programmed cell death, members of metabolic pathways, receptor modulators, and many other novel targets...
