Blood proteins in functional psychoses. A review of the literature and unifying hypothesis.

The question of abnormal blood proteins of various sorts in the functional psychoses has been rather extensively investigated. The work is scattered throughout the world literature and much of it is in Russian. The purpose of this paper is to bring together some of the important work of the last 10 years. Most of the literature reviewed is in English. Some of the Russian and Continental work has been covered, but the unavailability of some relevant papers and the difficulties of translation have limited the review of foreign work. Several theories about the role of abnormal protein metabolism in the etiology or pathogenesis of the functional psychoses have recently been proposed. Some 53-59 have suggested that a circulating protein, taraxein, produces the schizophrenic reaction. I 30-34 and others 123 have speculated that the psychotic reaction in some cases may result from an autoimmune reaction directed against
Cost sharing, adherence, and health outcomes in patients with diabetes.

OBJECTIVES To assess the relationship between cost sharing and adherence to antidiabetic medications in patients with type 2 diabetes and to examine the relationship between medication adherence and outcomes, including complication rates, medical service utilization, and workplace productivity measures. STUDY DESIGN A retrospective, cross-sectional study analyzing the healthcare experience of patients with type 2 diabetes on oral antidiabetic medication (OAD) with or without insulin (n = 96,734) and patients on OAD only (n = 55,356) with employer-sponsored insurance in the 2003-2006 MarketScan Database. METHODS Using a 2-stage residual inclusion model, the first stage estimated the effects of cost sharing on adherence to antidiabetic medications in an 18-month time frame (January 2003 through June 2004). Adherence was determined from the percentage of days covered. The second stage estimated the effects of adherence on complication rates (eg, retinopathy, neuropathy, peripheral vascular disease), medical service utilization rates, and measures of productivity (absence days and short-term disability days) in the subsequent 2 years (July 2004 through June 2006). RESULTS A $10 increase in the patient cost-sharing index resulted in a 5.4% reduction in adherence to antidiabetic medications for patients on OAD only and a 6.2% reduction in adherence for patients on OAD with or without insulin. Adherence was associated with lower rates of complications (eg, amputation/ulcers, retinopathy) and also was associated with fewer emergency department visits and short-term disability days. CONCLUSIONS Medical plans, employers, and policy makers should consider implementing interventions targeted to improve antidiabetic medication adherence, which may translate to better outcomes.
Comparative Studies of Periphyton Diversity on Added Substrata in Fish Pond and Minor Reservoir

The present study deals with the comparative studies of periphyton diversity on added substrata, bamboo poles in two water bodies, a fish pond and a minor reservoir. The size of fish pond is 0.1 ha. and reservoir is 21.00 ha, but only a part (0.1 ha) of the reservoir is used for this study. The periphyton study was carried out after harvesting fish in both the water bodies, i.e., without fish. The bamboo poles were arranged at the rate of one pole/10m. The periphyton was analyzed after a month. Diversified periphyton communicates were found on bamboo poles. These belong to chlorphyceae, cyanophyceae basillariophyceae and euglenophyceae of algae and zooplankton in the fish pond whereas, bacterial and macroinvertebrates along with above group of organisms in the part of reservoir. In both the cases, periphyton was dominated by diatoms, followed by green algae and blue-greens. Diatoms most abundantly found in both water bodies. The periphyton was found more in fish pond when compared to the reservoir due to the application of manures in the pond during fish culture.
Trans-Tasman Sea larval transport: Is Australia a source for New Zealand rock lobsters?

Two species of rock lobster (Palinuridae) are commonly found in coastal waters around both New Zealand and Australia. Both species have a relatively long larval phase, which raises the question of how populations can be maintained in regions where the mean flow advects larvae away from the coast. Previous work shows that Jasus edwardsii is genetically indistinguishable between Australia and New Zealand, whereas Sagmariasus verreauxi may be genetically different between the 2 countries. Satellite altimeter data are used here to test the hypothesis that Australia acts as a source of larvae for some New Zealand populations, and to investigate if there is a physical mecha- nism for the apparent lack of gene flow for S. verreauxi. A Lagrangian approach is used in which the western Tasman Sea is seeded with numerical drifters to build up a statistical summary of the likely distribution of larval trajectories. Ignoring biological factors, about 9% of J. edwardsii and about 2% of S. verreauxi larvae might be expected to arrive in New Zealand waters within their respective larval lifetimes. An order-of-magnitude estimate shows that even with extremely high mortality, these rates are high enough for trans-Tasman larval flow to contribute to and possibly maintain some New Zealand populations. Larval flow across the Tasman Sea should be sufficient to maintain trans- Tasman genetic homogeneity in both species. We suggest that 1 reason that S. verreauxi may not be genetically homogenous is that in order to arrive in New Zealand within 1 larval lifetime, they have to cross the Tasman Sea north of the productive Subtropical Front where there is not enough prey to sustain them.
Acute stress disorder as a predictor of posttraumatic stress: A longitudinal study of Chinese children exposed to the Lushan earthquake.

This study examined the prevalence of acute stress disorder (ASD) and posttraumatic stress disorder (PTSD) in children who experienced the Lushan earthquake in Sichuan, China, and assessed the ability of ASD to predict PTSD. The Acute Stress Disorder Scale (ASDS) was used to assess acute stress reaction within weeks of the trauma. The University of California at Los Angeles Post-Traumatic Stress Disorder Reaction Index (UCLA-PTSD) for children was administered at intervals of 2, 6, and 12 months after the earthquake to 197 students who experienced the Lushan earthquake at the Longxing Middle School. The results demonstrated that 28.4% of the children suffered from ASD, but only a small percentage of the population went on to develop PTSD. Among all of the students, 35.0% of those who met the criteria for ASD were diagnosed with PTSD at the 12-month interval. The severity of ASD symptoms correlated with later PTSD symptoms.
Phylogenetic patterns differ for native and exotic plant communities across a richness gradient in Northern California

Aim Increasingly, ecologists are using evolutionary relationships to infer the mechanisms of community assembly. However, modern communities are being invaded by non‐indigenous species. Since natives have been associated with one another through evolutionary time, the forces promoting character and niche divergence should be high. On the other hand, exotics have evolved elsewhere, meaning that conserved traits may be more important in their new ranges. Thus, co‐occurrence over sufficient time‐scales for reciprocal evolution may alter how phylogenetic relationships influence assembly. Here, we examined the phylogenetic structure of native and exotic plant communities across a large‐scale gradient in species richness and asked whether local assemblages are composed of more or less closely related natives and exotics and whether phylogenetic turnover among plots and among sites across this gradient is driven by turnover in close or distant relatives differentially for natives and exotics.
Role of simian virus 40 gene A function in maintenance of transformation

Mouse, hamster, and human cells were transformed at the permissive temperature by mutants from simian virus 40 (SV40) complementation group A in order to ascertain the role of the gene A function in transformation. The following parameters of transformation were monitored with the transformed cells under permissive and nonpermissive conditions: morphology; saturation density; colony formation on plastic, on cell monolayers, and in soft agar; uptake of hexose; and the expression of SV40 tumor (T) and surface (S) antigens. Cells transformed by the temperature-sensitive (ts) mutants exhibited the phenotype of transformed cells at the nonrestrictive temperature for all of the parameters studied. However, when grown at the restrictive temperature, they were phenotypically similar to normal, untransformed cells. Growth curves showed that the (ts) A mutant-transformed cells exhibited the growth characteristics of wild-type virus-transformed cells at the permissive temperature and resembled normal cells when placed under restrictive conditions. There were 3-to 51-fold reductions in the levels of saturation density, colony formation, and uptake of hexose when the mutant-transformed cells were the elevated temperature as compared to when they were grown at the permissive temperature. Mutant-transformed cells from the nonpermissive temperature were able to produce transformed foci when shifted down to permissive conditions, indicating that the phenotypically reverted cells were still viable and that the reversion was a reversible event. SV40 T antigen was present in the cells at both temperatures, but S antigen was not detected in cells maintained at the nonpremissive temperature. All of the wild-type virus-transformed cells exhbited a transformed cells exhibited a transformed phenotype when grown under either restrictive or nonrestrictive conditions. Thers results indicate that the SV40 group A mutant-transformed cells are temperature sensitive for the maintenance of growth properties characteristics of transformation. Virus rescued from the mutant-transformed cells by the transfection method was ts, suggesting that the SV40 gene A function, rather than a cellular one, is responsible for the ts behavior of the cells.
Neuroprotection, neuroregeneration, and interaction with insulin‐like growth factor‐I: novel non‐anticoagulant action of glycosaminoglycans

We present recent developments in the area of glycosaminoglycans (GAGs) and their possible interaction with insulin‐like growth factor‐I (IGF‐I). GAGs are constituents of proteoglycans, and the combination of a core protein and a specific GAG makes a unique proteoglycan with a precise developmental pattern and with the ability to bind growth factors. This process is apparently regulated by the moiety of the peripheral GAGs. The supplementation of GAGs promotes neuritogenesis in vitro and stimulates nerve regrowth and muscle reinnervation, an effect correlated with an increase in trophic factor mRNA expression. In the case of neonatal nerve lesion, there is in addition an enhanced motor neuron survival, accompanied by higher levels of IGF‐I in plasma and denervated muscle. The neurotrophic and neuroregenerative effects of exogenous GAGs were also observed in motor neuron disease in the wobbler mouse. J. Neurosci. Res. 51:559–562, 1998. © 1998 Wiley‐Liss, Inc.
Progress in the Integrated Simulation of Thermal-Hydraulic Operation of the ITER Magnet System

A new integrated computer code is being developed for the simulations of the overall behavior of the ITER magnet cryo-system. The existing THEA, FLOWER and POWER codes, assembled as modules of a computational environment (SuperMagnet) have been upgraded to perform global simulations of the cooling circuit for the ITER magnet system. The thermal coupling resulting from the generic geometric configurations has been implemented to realize quasi-three-dimensional simulations of the winding pack. In this paper we present details on the model.
Platelet microparticles and vascular cells interactions: A checkpoint between the haemostatic and thrombotic responses

Described 40 years ago as cell dust, microparticles (MPs) are now considered a key component in the haemostatic response. Owing to their plasma membrane reactivity, platelets are believed to constitute the main source of circulating procoagulant microparticles and behave as true sensors for the haemostatic response. Erythrocytes, leukocytes and endothelial cells are also able to shed MPs in the blood flow, their respective contribution varying with the pathophysiologic circumstances and extent of the cellular damage. The catalytic properties of MPs rely on a procoagulant anionic phospholipid, phosphatidylserine, made accessible at the outer leaflet following plasma membrane remodelling and on the eventual presence of tissue factor (TF). Under resting conditions, most membrane-bound TF is encrypted. Although able to bind to FVIIa, it does not trigger blood coagulation. Under prothrombotic conditions, TF decryption would occur through intricate pathways involving platelets, monocytes, endothelial cells and derived MPs. P-selectin/P-selectin glycoprotein Ligand-1 (PSGL-1) interactions and reactive oxygen species would promote TF decryption in cell-MP aggregates. At sites of endothelium injury, the swift recruitment of TF+-MPs through P-selectin/PSGL-1 interactions enables the concentration of TF activity above a threshold allowing coagulation to be triggered. Another crucial feature in the initiation of blood coagulation, possibly tuned by MPs, is the balance between TF and TFPI. In specific pathophysiologic contents with elevated levels of circulating TF+-MPs, accessible TFPI at the MP surface would be overwhelmed. Beyond their procoagulant properties demonstrated in vitro, a number of pieces of evidence points to procoagulant MPs as efficient effectors in the haemostatic response, and as pathogenic markers of thrombotic disorders and vascular damage. This review will focus on the pathophysiological significance of platelet-derived MPs and their interaction with vascular cells.
Estimation of Serum Micronutrient Levels and The Possible Risk Of Oral Cancer And Premalignancy

The oral cancer is one of the most prevalent type of cancer worldwide. It is invariably linked to lifestyle habits like alcohol consumption, cigarette smoking and poor nutritional status. This apart, the role of micronutrients in oral carcinogenesis still remains less understood. So the study was undertaken to assess the micronutrient levels of oral cancer and precancerous patients.The estimation of Haemoglobin showed there was no significant difference between controls, premalignancy cases and in cancerous conditions. Zinc and copper level levels were significantly lower in cases than in controls . There is a positive correlation between serum iron and selenium level and oral cancer patients, yet we didn’t find significant increase in serum iron level either in precancerous or oral cancer patients. This study may indicate that very high or low levels of micronutrients associated with oral carcinoma. Yet moderate amount of micronutrients in diet may have protective effect on oral carcinoma which requires further research in these lines.
Using the Chronic Care Model to Address Tobacco in Health Care Delivery Organizations: A Pilot Experience in Washington State

This article describes a Washington State—based Systems Change Pilot Project in which the chronic care model and the model for improvement were used as tools to promote tobacco cessation—related changes within a health care system. Three diverse sites participated in the pilot. Site teams tailored plan-do-study-act tests to site circumstances, addressing current resources and barriers to implementing change. Teams tested system changes that incorporated tobacco use documentation into the routine health services provided. Findings from this pilot suggest that (a) even simple changes with minimal disruption of services can make a difference in improving documentation of tobacco use status; (b) changes to routine practices of health organizations may not be sustainable if ongoing quality assurance mechanisms are not developed; and (c) systems implemented for other disease states within the same organization or patient population are not instinctively applied to tobacco, because of a multitude of factors.
Left ventricular diastolic filling pattern predicts cardiopulmonary determinants of functional capacity in patients with congestive heart failure.

BACKGROUND Abnormalities of diastolic function are an important determinant of exercise intolerance in patients with heart failure. However, the relation between left ventricular filling pattern and cardiopulmonary exercise performance has not been adequately studied. METHODS Thirty-one patients with idiopathic (n = 14) or ischemic (n = 17) dilated cardiomyopathy, demonstrated by coronary angiography, and radionuclide ejection fraction 30.5% +/- 9% underwent cardiopulmonary exercise testing with a modified Naughton protocol and a complete echocardiographic study. Patients were subdivided into restrictive and nonrestrictive groups according to their Doppler transmitral flow pattern. Gas exchange data were measured during exercise testing. The relation of left ventricular filling pattern to cardiopulmonary parameters was assessed in both groups. RESULTS Exercise duration was similar in the restrictive and nonrestrictive groups but significant differences were found in oxygen consumption (VO(2)) at peak exercise (14.3 +/- 2.4 vs 20.4 +/- 4.7 mL/kg per minute; P <.001) and at the anaerobic threshold (VO(2AT)) (13 +/- 2.2 vs 17.3 +/- 3 mL/kg per minute; P <.001). Simple linear regression analysis revealed that both peak VO(2) and VO(2AT) were significantly correlated with the ratio of peak early (E wave) to late (A wave) transmitral filling velocity, early filling deceleration time, atrial filling fraction, and A-wave velocity but not with left ventricular ejection fraction. Multivariate regression analysis gave only the peak A-wave velocity as an independent predictor for both peak VO(2) and VO(2AT). CONCLUSIONS In patients with heart failure, abnormalities of diastolic function are the most important determinant of exercise intolerance. A restrictive transmitral flow pattern by Doppler echocardiography is a marker of diminished cardiopulmonary exercise performance in these patients.
Therapeutic Efficacy of Liposome-Encapsulated Gentamicin in Rat Klebsiella pneumoniae Pneumonia in Relation to Impaired Host Defense and Low Bacterial Susceptibility to Gentamicin

ABSTRACT Long-circulating liposomes (LCL) may be used as targeted antimicrobial drug carriers as they localize at sites of infection. As a result, LCL-encapsulated gentamicin (LE-GEN) has demonstrated superior antibacterial activity over the free drug in a single-dose study of immunocompetent rats with Klebsiella pneumoniaepneumonia. In the present study, the therapeutic efficacy of LE-GEN was evaluated by monitoring rat survival and bacterial counts in blood and lung tissue in clinically relevant models, addressing the issue of impaired host defense and low bacterial antibiotic susceptibility. The results show that in immunocompetent rats infected with the high-GEN-susceptibility K. pneumoniae strain, a single dose of LE-GEN is clearly superior to an equivalent dose of free GEN. Yet complete survival can also be obtained with multiple doses of free GEN. In leukopenic rats infected with the high-GEN-susceptible K. pneumoniae strain, free GEN at the maximum tolerated dose (MTD) was needed to obtain survival. However, with the addition of a single dose of LE-GEN to free-GEN treatment, complete survival can be obtained using a sevenfold-lower cumulative amount of GEN than with free-GEN treatment alone. In leukopenic rats infected with low-GEN-susceptibleK. pneumoniae cells, free GEN at the MTD did not result in survival. The use of LE-GEN is needed for therapeutic success. Increasing LE-GEN bilayer fluidity resulted in an increased GEN release from the liposomes and hence improved rat survival, thus showing the importance of the liposome lipid composition for therapeutic efficacy. These results warrant further clinical studies of liposomal formulations of aminoglycosides in immunocompromised patients with severe infections.
Classroom Friends and Very Best Friends: A Short-Term Longitudinal Analysis of Relationship Quality

ABSTRACT Second-, third-, fifth-, and sixth-grade children evaluated relationship qualities of a self-nominated friend and a self-nominated very best friend over a 6-month school year period. Results demonstrated that 76% of the friend relationships and 50% of the very best friend relationships were maintained over the course of the study. Children in maintained friendships evaluated their relationships more positively and also reported having larger friendship networks in general compared with children whose friendships did not endure over time. Thus those with unstable relationships are having difficulty initiating new friendships as well. For very best friends, positive relationship qualities (e.g., caring) did not change over time for children in maintained relationships, while positive relationship qualities decreased over time for children in nonmaintained relationships. Further, no differences emerged between children in maintained and nonmaintained very best friendships on perceptions of negative relationship qualities (e.g., conflict).
Stimulation of p53-mediated Transcriptional Activation by the p53-binding Proteins, 53BP1 and 53BP2*

p53 is a tumor suppressor protein that controls cell proliferation by regulating the expression of growth control genes. In a previous study, we identified two proteins, 53BP1 and 53BP2, that are able to bind to wild type but not to mutant p53 via the DNA-binding domain of p53. We isolated cDNAs expressing a full-length human 53BP1 clone, which predicts a protein of 1972 residues that can be detected in the H358 human lung carcinoma cell line. The 53BP1 and 53BP2 genes were mapped to chromosomes 15q15–21 and 1q41–42, respectively. Immunofluorescence studies showed three types of staining patterns for 53BP1 as follows: both cytoplasmic and nuclear, homogeneous nuclear, and a nuclear dot pattern. In contrast, 53BP2 localized exclusively to the cytoplasm, and this pattern did not change upon coexpression of wild type p53. Although our previous study revealed that p53 is not able to bind simultaneously to either 53BP1 or 53BP2 and to DNA carrying a consensus binding site, both 53BP1 and 53BP2 enhanced p53-mediated transcriptional activation and induced the expression of a p53-dependent protein, suggesting that these proteins might function in signal transduction pathways to promote p53 activity.
