Cancer statistics, 2013 (2013)

Each year, the American Cancer Society estimates the numbers of new cancer cases and deaths expected in the United States in the current year and compiles the most recent data on cancer incidence, mortality, and survival based on incidence data from the National Cancer Institute, the Centers for Disease Control and Prevention, and the North American Association of Central Cancer Registries and mortality data from the National Center for Health Statistics. A total of 1,660,290 new cancer cases and 580,350 cancer deaths are projected to occur in the United States in 2013. During the most recent 5 years for which there are data (2005-2009), delay-adjusted cancer incidence rates declined slightly in men (by 0.6% per year) and were stable in women, while cancer death rates decreased by 1.8% per year in men and by 1.5% per year in women. Overall, cancer death rates have declined 20% from their peak in 1991 (215.1 per 100,000 population) to 2009 (173.1 per 100,000 population). Death rates continue to decline for all 4 major cancer sites (lung, colorectum, breast, and prostate). Over the past 10 years of data (2000-2009), the largest annual declines in death rates were for chronic myeloid leukemia (8.4%), cancers of the stomach (3.1%) and colorectum (3.0%), and non-Hodgkin lymphoma (3.0%). The reduction in overall cancer death rates since 1990 in men and 1991 in women translates to the avoidance of approximately 1.18 million deaths from cancer, with 152,900 of these deaths averted in 2009 alone. Further progress can be accelerated by applying existing cancer control knowledge across all segments of the population, with an emphasis on those groups in the lowest socioeconomic bracket and other underserved populations.
Neuropeptide S stimulates dopaminergic neurotransmission in the medial prefrontal cortex (2010)

Neuropeptide S (NPS) is known to produce anxiolytic-like effects and facilitate extinction of conditioned fear. Catecholaminergic neurotransmission in the medial prefrontal cortex (mPFC) has been suggested to be crucially involved in these brain functions. In the current study, we investigated the effect of NPS on the release of dopamine and serotonin in the mPFC by in vivo microdialysis in rats. Central administration of NPS dose-dependently enhanced extracellular levels of dopamine and its major metabolite 3,4-dihydroxyphenylacetic acid, with maximal effects lasting up to 120 min. In contrast, no effect on serotonergic neurotransmission was detected. Dopamine release in the mPFC has been previously linked to modulation of anxiety states and fear extinction. The present results may thus provide a physiological and anatomical basis for the reported effects of NPS on these behaviors.
Bacteruria with group-B streptococcus: is it a risk factor for adverse pregnancy outcomes? (2012)

Our study showed a significant association between U-GBS and adverse obstetrical outcomes. In addition a linear association was found between GBS culture location and obstetric complications. However, GBS was not associated with adverse perinatal outcome in our population.

Enzyme-catalyzed Synthesis and Degradation of Biopolymers (2009)

The synthesis and degradation of biopolymers are cardinal reactions that take place to maintain homeostasis in biosystems. Fundamental biological reactions can be reproduced in vitro by means of enzyme-mediated processes. Recently, bioprocesses have been extensively adopted to synthesize representative biopolymers, including aliphatic polyesters, e.g., polyhydroxyalkanoate (PHA). In particular, the protein engineering of enzymes involved in PHA synthesis has made a great impact on the tailor-made synthesis of polymer materials with high performance. Biopolymers can also be synthesized in vitro by enzyme-catalyzed polymerization using synthetic enzymes and depolymerase-mediated reverse reactions. We will describe these advanced topics from the viewpoint of the boundary field between chemistry and biotechnology. Keywords: Biopolymer, polyhydroxyalkanoate (PHA), PHA synthase, enzyme evolution, PHB depolymerase, lipase
Reduced Food Intake and Body Weight in Mice Treated with Fatty Acid Synthase Inhibitors (2000)

With the escalation of obesity-related disease, there is great interest in defining the mechanisms that control appetite and body weight. We have identified a link between anabolic energy metabolism and appetite control. Both systemic and intracerebroventricular treatment of mice with fatty acid synthase (FAS) inhibitors (cerulenin and a synthetic compound C75) led to inhibition of feeding and dramatic weight loss. C75 inhibited expression of the prophagic signal neuropeptide Y in the hypothalamus and acted in a leptin-independent manner that appears to be mediated by malonyl-coenzyme A. Thus, FAS may represent an important link in feeding regulation and may be a potential therapeutic target.
TGR5 as a Therapeutic Target for Treating Obesity (2010)

TGR5 (also known as GPBAR1, M-BAR, BG37, hGPCR19, and AXOR 109) is a specific membrane G-protein-coupled receptor (GPCR) of bile acids (BAs). It has recently become an attractive therapeutic target for the prevention and/or the treatment of obesity and its highly associated Type II diabetes and metabolic syndrome. It has also been implicated in many other inflammatory, cardiovascular, neurological, and hepatic diseases. This review briefly describes the biological rationale of TGR5 as an attractive therapeutic target and summarizes some recent efforts on the development of TGR5 modulators.

Early growth response 1 regulates glucose deprivation-induced necrosis (2012)

Necrosis is commonly found in the core region of solid tumours due to metabolic stress such as hypoxia and glucose deprivation (GD) resulting from insufficient vascularization. Necrosis promotes tumour growth and development by releasing the tumour-promoting cytokine high mobility group box 1 (HMGB1); however, the molecular mechanism underlying necrotic cell death remains largely unknown. In this study, we show that early growth response 1 (Egr-1) is induced in a reactive oxygen species (ROS)-dependent manner by GD in several cell lines such as A549, MDA-MB-231 and HepG2 cells that exhibit necrosis upon GD. We found that Egr-1 short hairpin RNA (shRNA) prevented GD-induced necrosis and HMGB1 release. Necrosis-inhibiting activity of Egr-1 shRNA was also seen in multicellular tumour spheroids (MTSs), an in vitro tumour model system. In contrast, Egr-1 overexpression appeared to make tumour cells more susceptible to GD-induced necrosis. Finally, Egr-1 shRNA suppressed the growth of MTSs. These findings demonstrate that Egr-1 is implicated in GD-induced necrosis and tumour progression.
Daytime Exposure to Short Wavelength-Enriched Light Improves Cognitive Performance in Sleep-Restricted College-Aged Adults (2021)

We tested the effect of daytime indoor light exposure with varying melanopic strength on cognitive performance in college-aged students who maintained an enforced nightly sleep opportunity of 7 h (i.e., nightly sleep duration no longer than 7 h) for 1 week immediately preceding the day of light exposure. Participants (<i>n</i> = 39; mean age ± SD = 24.5 ± 3.2 years; 21 F) were randomized to an 8 h daytime exposure to one of four white light conditions of equal photopic illuminance (~50 lux at eye level in the vertical plane) but different melanopic illuminance [24-45 melanopic-EDI lux (melEDI)] generated by varying correlated color temperatures [3000K (low-melEDI) or 5000K (high-melEDI)] and spectra [conventional or daylight-like]. Accuracy on a 2-min addition task was 5% better in the daylight-like high-melEDI condition (highest melEDI) compared to the conventional low-melEDI condition (lowest melEDI; <i>p</i> < 0.01). Performance speed on the motor sequence learning task was 3.2 times faster (<i>p</i> < 0.05) during the daylight-like high-melEDI condition compared to the conventional low-melEDI. Subjective sleepiness was 1.5 times lower in the conventional high-melEDI condition compared to the conventional low-melEDI condition, but levels were similar between conventional low- and daylight-like high-melEDI conditions. These results demonstrate that exposure to high-melanopic (short wavelength-enriched) white light improves processing speed, working memory, and procedural learning on a motor sequence task in modestly sleep restricted young adults, and have important implications for optimizing lighting conditions in schools, colleges, and other built environments.
Common susceptibility genes for cancer: search for the end of the rainbow (2006)

The human genome map has started a hunt to find common genes that are associated with cancer. But new research questions the likelihood of success.
The positive relationship between codon usage bias and translation initiation AUG context inSaccharomyces cerevisiae (1999)

The relationship between the codon usage bias and the sequence context surrounding the AUG translation initiation codon was examined in 211 Saccharomyces cerevisiae mRNA sequences. The codon usage bias and the number of matches to optimal AUG context, (A/U)A(A/C)AA(A/C)AUGUC(U/C), for translation initiation showed a positive relationship, indicating that these two factors are evolutionally under the similar natural selection constraint at the translation level. A new index (AUGCAI = AUG Context Adaptation Index) for the measure of optimal AUG context was devised, and the importance of each position of AUG context was also examined.
Differential Development of Salt-Induced and Renal Hypertension in Dahl Hypertension-Sensitive Rats After Neonatal Sympathectomy (1979)

Rats with a genetic susceptibility to salt hypertension were given repeated neonatal injections of guanethidine. Vascular reactivity and tissue catecholamine concentrations indicated that a peripheral sympathectomy had been produced. Chemically sympathectomized rats had lower blood pressure than controls while fed a diet containing 0.4% NaCl. Furthermore, the dramatic rise in blood pressure exhibited by control rats fed a diet containing 8.0% NaCl was completely absent in sympathectomized rats similarly fed. The absence of salt-induced hypertension was observed regardless of whether the animals were anesthetized with ether or pentobarbital or had the blood pressures determined in an unanesthetized state. Finally, two-kidney Goldblatt hypertension did develop in sympathectomized rats, but to a level below intact rats similarly treated.
Resistance of the antibacterial agent ceragenin CSA-13 to inactivation by DNA or F-actin and its activity in cystic fibrosis sputum (2007)

Charge-based interactions that strongly inhibit the antibacterial activity of host cationic antibacterial peptides present in CF sputa have significantly less effect on molecules from the ceragenin family such as CSA-13 due in part to their smaller net charge and distribution of this charge over a hydrophobic scaffold. CSA molecules therefore have potential for the treatment of chronic infections and inflammation that occur in CF airways and other settings in which extracellular polyanions accumulate.
Measuring acoustic energy density in microchannel acoustophoresis using a simple and rapid light-intensity method (2012)

We present a simple and rapid method for measuring the acoustic energy density in microchannel acoustophoresis based on light-intensity measurements of a suspension of particles. The method relies on the assumption that each particle in the suspension undergoes single-particle acoustophoresis. It is validated by the single-particle tracking method, and we show by proper re-scaling that the re-scaled light intensity plotted versus re-scaled time falls on a universal curve. The method allows for analysis of moderate-resolution images in the concentration range encountered in typical experiments, and it is an attractive alternative to particle tracking and particle image velocimetry for quantifying acoustophoretic performance in microchannels.
Combined Extraction of Cesium and Strontium from Alkaline Nitrate Solutions (2006)

Abstract The combined extraction of cesium and strontium from caustic wastes can be achieved by adding a crown ether and a carboxylic acid to the Caustic‐Side Solvent Extraction (CSSX) solvent. The ligand 4,4′(5′)‐di(tert‐butyl)cyclohexano‐18‐crown‐6 and one of four different carboxylic acids were combined with the components of the CSSX solvent optimized for the extraction of cesium, allowing for the simultaneous extraction of cesium and strontium from alkaline nitrate media simulating alkaline high level wastes present at the U.S. Department of Energy Savannah River Site. Extraction and stripping experiments were conducted independently and exhibited adequate results for mimicking waste simulant processing through batch contacts. The promising results of these batch tests showed that the system could reasonably be tested on actual waste.
Activation of the Cytoplasmic c-Abl Tyrosine Kinase by Reactive Oxygen Species (2000)

The ubiquitously expressed c-Abl protein tyrosine kinase localizes to both the nucleus and cytoplasm. The nuclear form of c-Abl is activated in the cellular response to genotoxic stress. Here we show that cytoplasmic c-Abl is activated by oxidative stress. The results also demonstrate that mitochondrial cytochrome c is released in the cellular response to H(2)O(2) and that this effect is mediated by a c-Abl-dependent mechanism. In concert with these results, we show that H(2)O(2)-induced apoptosis is attenuated in c-Abl-deficient cells. These findings demonstrate that cytoplasmic c-Abl is involved in the apoptotic response of cells to oxidative stress.

Identification of neutrophil gelatinase-associated lipocalin as a novel matrix protein of specific granules in human neutrophils (1994)

Neutrophil gelatinase-associated lipocalin (NGAL) is a novel 25-kD protein of human neutrophils, that is in part covalently complexed with neutrophil gelatinase. However, both NGAL and gelatinase exist mainly in forms not associated with each other. An explanation for this phenomenon might be that the unassociated proteins reside in different subcellular compartments. The aim of the present study was to determine the subcellular localization of NGAL. An enzyme-linked immunosorbent assay (ELISA) for NGAL was developed using specific anti-NGAL antibodies. The assay was applied on subcellular fractions of neutrophils obtained after centrifugation of a postnuclear supernatant on a two-layer Percoll gradient. The distribution profile of NGAL was found to colocalize strictly with the distribution profile of lactoferrin. This was confirmed by immunogold double-labeling of frozen thin sections of neutrophils that showed a high degree of colocalization of NGAL and lactoferrin, and by exocytosis experiments, which showed lactoferrin, vitamin B12-binding protein, and NGAL to be similarly released upon stimulation. Therefore, NGAL is a novel matrix protein of specific granules and thus partly segregated from gelatinase, the major part of which is located in a separate compartment, the gelatinase granules. An ELISA specific for the NGAL/gelatinase complex was developed and the subcellular distribution and release of this complex was determined. The distribution and mobilization of the complex allowed us to confirm the existence of differentially mobilized granule subpopulations among peroxidase negative granules.
Platelets, inflammation and tissue regeneration (2011)

Blood platelets have long been recognised to bring about primary haemostasis with deficiencies in platelet production and function manifesting in bleeding while upregulated function favourises arterial thrombosis. Yet increasing evidence indicates that platelets fulfil a much wider role in health and disease. First, they store and release a wide range of biologically active substances including the panoply of growth factors, chemokines and cytokines released from a-granules. Membrane budding gives rise to microparticles (MPs), another active participant within the blood stream. Platelets are essential for the innate immune response and combat infection (viruses, bacteria, micro-organisms). They help maintain and modulate inflammation and are a major source of pro-inflammatory molecules (e.g. P-selectin, tissue factor, CD40L, metalloproteinases). As well as promoting coagulation, they are active in fibrinolysis; wound healing, angiogenesis and bone formation as well as in maternal tissue and foetal vascular remodelling. Activated platelets and MPs intervene in the propagation of major diseases. They are major players in atherosclerosis and related diseases, pathologies of the central nervous system (Alzheimers disease, multiple sclerosis), cancer and tumour growth. They participate in other tissue-related acquired pathologies such as skin diseases and allergy, rheumatoid arthritis, liver disease; while, paradoxically, autologous platelet-rich plasma and platelet releasate are being used as an aid to promote tissue repair and cellular growth. The above mentioned roles of platelets are now discussed.
Dietary restriction and 2‐deoxyglucose administration improve behavioral outcome and reduce degeneration of dopaminergic neurons in models of Parkinson's disease (1999)

Parkinson's disease (PD) is an age-related disorder characterized by progressive degeneration of dopaminergic neurons in the substantia nigra (SN) and corresponding motor deficits. Oxidative stress and mitochondrial dysfunction are implicated in the neurodegenerative process in PD. Although dietary restriction (DR) extends lifespan and reduces levels of cellular oxidative stress in several different organ systems, the impact of DR on age-related neurodegenerative disorders is unknown. We report that DR in adult mice results in resistance of dopaminergic neurons in the SN to the toxicity of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP). MPTP-induced loss of dopaminergic neurons and deficits in motor function were ameliorated in DR rats. To mimic the beneficial effect of DR on dopaminergic neurons, we administered 2-deoxy-D-glucose (2-DG; a nonmetabolizable analogue of glucose) to mice fed ad libitum. Mice receiving 2-DG exhibited reduced damage to dopaminergic neurons in the SN and improved behavioral outcome following MPTP treatment. The 2-DG treatment suppressed oxidative stress, preserved mitochondrial function, and attenuated cell death in cultured dopaminergic cells exposed to the complex I inhibitor rotenone or Fe2+. 2-DG and DR induced expression of the stress proteins heat-shock protein 70 and glucose-regulated protein 78 in dopaminergic cells, suggesting involvement of these cytoprotective proteins in the neuroprotective actions of 2-DG and DR. The striking beneficial effects of DR and 2-DG in models of PD, when considered in light of recent epidemiological data, suggest that DR may prove beneficial in reducing the incidence of PD in humans.
