A clinical study on the tip localization of peripherally inserted central catheter (PICC) guided by intracavitary electrocardiography in newborns: a randomised trial.

Background: The present study aimed to investigate the P-wave changes in intracavitary electrocardiography (IC-ECG) during catheterization with a peripherally inserted central catheter (PICC) in order to provide guidance for the accurate localization of the tip of the PICC.

Methods: A total of 106 newborns who needed a PICC were randomly divided into two groups-a study group and a control group-using a random number table, with 53 cases in each group. In the study group, the ECG monitor was connected after the successful puncture and insertion of the PICC into the right sternoclavicular joint, and the position of the catheter tip was determined according to the P-wave changes on the IC-ECG.

Protraction of mandibular molars through a severely atrophic edentulous space in a case of juvenile periodontitis.

Moving the mandibular posterior teeth into a severely atrophic edentulous space is a challenge. A carefully designed force-and-moment system that results in bodily protraction of the posterior teeth with balanced bone resorption and apposition is needed in such cases. This report describes the treatment of a 19-year-old woman with missing mandibular first molars due to juvenile periodontitis.

Mitochondria-associated lactate dehydrogenase is not a biologically significant contributor to bioenergetic function in murine striated muscle.

Previous studies indicate that mitochondria-localized lactate dehydrogenase (mLDH) might be a significant contributor to metabolism. In the heart, the presence of mLDH could provide cardiac mitochondria with a higher capacity to generate reducing equivalents directly available for respiration, especially during exercise when circulating lactate levels are high. The purpose of this study was to test the hypothesis that mLDH contributes to striated muscle bioenergetic function.

Methylation mediated Gadd45β enhanced the chemosensitivity of hepatocellular carcinoma by inhibiting the stemness of liver cancer cells.

Background: Defects of the growth arrest DNA damage-inducible gene 45β (Gadd45β) play an important role in the progression of tumor and confer resistance to chemotherapy. However, the role of Gadd45β in the apoptosis of hepatocellular carcinoma is still not clear. Purpose of this study was to explore the effect of Gadd45β on the apoptosis of liver cancer cells, and the possible mechanism was examined.

Integration of flux measurements to resolve changes in anabolic and catabolic metabolism in cardiac myocytes.

Although ancillary pathways of glucose metabolism are critical for synthesizing cellular building blocks and modulating stress responses, how they are regulated remains unclear. In the present study, we used radiometric glycolysis assays, [C]-glucose isotope tracing, and extracellular flux analysis to understand how phosphofructokinase (PFK)-mediated changes in glycolysis regulate glucose carbon partitioning into catabolic and anabolic pathways. Expression of kinase-deficient or phosphatase-deficient 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase in rat neonatal cardiomyocytes co-ordinately regulated glycolytic rate and lactate production.

High glucose induces mitochondrial dysfunction independently of protein O-GlcNAcylation.

Diabetes is characterized by hyperglycaemia and perturbations in intermediary metabolism. In particular, diabetes can augment flux through accessory pathways of glucose metabolism, such as the hexosamine biosynthetic pathway (HBP), which produces the sugar donor for the β-O-linked-N-acetylglucosamine (O-GlcNAc) post-translational modification of proteins. Diabetes also promotes mitochondrial dysfunction.

[Identification of mammalian blood meals in anopheline mosquitoes from four counties of Yunnan Province by multiple PCR].

From June to August 2012, the blood-sucking mosquitoes were captured around cattle-sheds and human houses in Yuanjiang County, Qiaojia County, Yongshan County, and Jinghong City of Yunan Province. Blood samples from mosquitoes were collected on filter paper. Multiplex PCR assay was used to detect the blood meal samples.

Age and dark rearing bidirectionally regulate the level and laminar pattern of expression of Abelson interacting protein 2 (Abi-2): a novel candidate visual cortical plasticity gene.

Electrophysiological studies indicate that cat visual cortical critical period neuronal plasticity peaks around 5 weeks and largely disappears by 20 weeks. Dark rearing slows this time course. Normal cats are more plastic than dark-reared cats at 5 weeks, but the opposite is true at 20 weeks.

Cardiomyocyte-restricted overexpression of extracellular superoxide dismutase increases nitric oxide bioavailability and reduces infarct size after ischemia/reperfusion.

Increased levels of extracellular superoxide dismutase (ecSOD) induced by preconditioning or gene therapy protect the heart from ischemia/reperfusion injury. To elucidate the mechanism responsible for this action, we studied the effects of increased superoxide scavenging on nitric oxide (NO) bioavailability in a cardiac myocyte-specific ecSOD transgenic (Tg) mouse. Results indicated that ecSOD overexpression increased cardiac myocyte-specific ecSOD activity 27.

Identification of α-chimaerin as a candidate gene for critical period neuronal plasticity in cat and mouse visual cortex.

Background: In cat visual cortex, critical period neuronal plasticity is minimal until approximately 3 postnatal weeks, peaks at 5 weeks, gradually declines to low levels at 20 weeks, and disappears by 1 year of age. Dark rearing slows the entire time course of this critical period, such that at 5 weeks of age, normal cats are more plastic than dark reared cats, whereas at 20 weeks, dark reared cats are more plastic. Thus, a stringent criterion for identifying genes that are important for plasticity in visual cortex is that they show differences in expression between normal and dark reared that are of opposite direction in young versus older animals.

Acrolein activates matrix metalloproteinases by increasing reactive oxygen species in macrophages.

Acrolein is a ubiquitous component of environmental pollutants such as automobile exhaust, cigarette, wood, and coal smoke. It is also a natural constituent of several foods and is generated endogenously during inflammation or oxidation of unsaturated lipids. Because increased inflammation and episodic exposure to acrolein-rich pollutants such as traffic emissions or cigarette smoke have been linked to acute myocardial infarction, we examined the effects of acrolein on matrix metalloproteinases (MMPs), which destabilize atherosclerotic plaques.

Identification of disabled-1 as a candidate gene for critical period neuroplasticity in cat and mouse visual cortex.

Rearing in darkness slows the time course of the critical period in visual cortex, such that at 5 weeks of age normal cats are more plastic than dark-reared cats, whereas at 20 weeks dark-reared cats are more plastic [G. D. Mower (1991)Dev.

Protein kinase Cepsilon interacts with and inhibits the permeability transition pore in cardiac mitochondria.

Although functional coupling between protein kinase Cepsilon (PKCepsilon) and mitochondria has been implicated in the genesis of cardioprotection, the signal transduction mechanisms that enable this link and the identities of the mitochondrial proteins modulated by PKCepsilon remain unknown. Based on recent evidence that the mitochondrial permeability transition pore may be involved in ischemia/reperfusion injury, we hypothesized that protein-protein interactions between PKCepsilon and mitochondrial pore components may serve as a signaling mechanism to modulate pore function and thus engender cardioprotection. Coimmunoprecipitation and GST-based affinity pull-down from mouse cardiac mitochondria revealed interaction of PKCepsilon with components of the pore, namely voltage-dependent anion channel (VDAC), adenine nucleotide translocase (ANT), and hexokinase II (HKII).
