OBJECTIVE
To test whether a theory-based, literacy, and culturally tailored self-management intervention, Latinos en Control, improves glycemic control among low-income Latinos with type 2 diabetes.

RESEARCH DESIGN AND METHODS
A total of 252 patients recruited from community health centers were randomized to the Latinos en Control intervention or to usual care. The primarily group-based intervention consisted of 12 weekly and 8 monthly sessions and targeted knowledge, attitudes, and self-management behaviors. The primary outcome was HbA1c. Secondary outcomes included diet, physical activity, blood glucose self-monitoring, diabetes knowledge and self-efficacy, and other physiological factors (e.g., lipids, blood pressure, and weight). Measures were collected at baseline and at 4- and 12-month follow-up. Change in outcomes over time between the groups and the association between HbA1c and possible mediators were estimated using mixed-effects models and an intention-to-treat approach.

RESULTS
A significant difference in HbA1c change between the groups was observed at 4 months (intervention −0.88 [−1.15 to −0.60] versus control −0.35 [−0.62 to 0.07], P &lt; 0.01), although this difference decreased and lost statistical significance at 12 months (intervention −0.46 [−0.77 to −0.13] versus control −0.20 [−0.53 to 0.13], P = 0.293). The intervention resulted in significant change differences in diabetes knowledge at 12 months (P = 0.001), self-efficacy (P = 0.001), blood glucose self-monitoring (P = 0.02), and diet, including dietary quality (P = 0.01), kilocalories consumed (P &lt; 0.001), percentage of fat (P = 0.003), and percentage of saturated fat (P = 0.04). These changes were in turn significantly associated with HbA1c change at 12 months.

CONCLUSIONS
Literacy-sensitive, culturally tailored interventions can improve diabetes control among low-income Latinos; however, strategies to sustain improvements are needed.

Published: March 2011

Abstract
In this paper, we introduce an iterative algorithm for finding a common element of the set of solutions of a mixed equilibrium problem, the set of fixed points of a nonexpansive mapping, and the the set of solutions of a variational inclusion in a real Hilbert space. Furthermore, we prove that the proposed iterative algorithm converges strongly to a common element of the above three sets, which is a solution of a certain optimization problem related to a strongly positive bounded linear operator.

Abstract
Promise of cell therapy has advanced the use of adult stem cells towards the development of novel approaches to promote regeneration of injured endothelium. The aim of this study was to stimulate endothelial progenitor cells (EPCs) with lectin isolated from Solanum tuberosum (potato) shoot and Calendula officinalis (marigold) extracts, in order to increase EPCs proliferation and gene expression of molecules with roles in chemotaxis and adhesion for a better attachment to injured vascular tissue. EPCs were differentiated from umbilical cord blood-derived mononuclear cells and characterized by light microscopy, flow cytometry, and vascular tube-like structures formation on Matrigel. Cell proliferation was determined by MTS assay, and gene expression of molecules involved in EPCs adhesion (VCAM-1, VE-cadherin, ICAM-1, PECAM-1, P-selectin) and chemotaxis was determined (CXCR4, Tie-2) by RT-PCR. For the assessment of cell motility, wound-healing assay was employed. Both potato shoot lectin and marigold extracts stimulated EPCs proliferation in a concentration dependent manner and were able to increase expression of adhesion and chemotactic molecules. Marigold flower extract proved to be more efficient. This study demonstrates the usefulness of potato lectin and marigold extracts to increase EPCs proliferation and modulate gene expression of chemotactic and adhesion molecules, which may facilitate EPCs attachment to injured endothelium.

Published: March 2011

AbstractA novel and easy method for the separation of inorganic anions by capillary electrophoresis using a polymeric ionic liquid (PIL), poly(1-vinyl-3-butylimidazolium bromide) as a background electrolyte modifier has been developed. The PIL has been proved to generate a reversed electroosmotic flow which reduces the analysis time and improves the separation significantly. Effects of the PIL concentration and buffer composition (pH and concentration) were evaluated on basis of the resolution and efficiency of the sample. Under optimum conditions, good separation of six model inorganic anions was achieved with high efficiency and excellent reproducibility within 3 min. The results obtained indicate that the combination of reversed EOF and the association between the analytes and the PIL on the capillary wall or BGE play a prominent role in the separation of anions. Therefore, the PIL presents a useful alternative for the BGE modifier in the study of inorganic anions by CE.

AbstractA novel platinum(IV) coordination compound with 6-mercaptopurine (6-Hmp) has been synthesised and characterised by IR and NMR spectroscopy. Spectroscopic parameters indicate the presence of two chelate (S-6, N-7) monodeprotonated ligands and two chloride ions in the coordination sphere of [PtCl2(6-mp)2] · H2O (I). Two Pt(IV) coordination compounds, [PtCl2(6-mp)2] · H2O (I) and [PtCl4(dbtp)2] (II), were used in the in vivo test against B16 mouse melanoma tumours. Cytotoxic activity of compound II against the tumour cells was found to be high (LC10 = 2.6 μM, LC50 = 17.0 μM, LC90 = 58.0 μM) compared to that of cisplatin.

AbstractA series of forty-five derivatives of 3-phenyl-4-thioxo-2H-1,3-benzoxazine-2(3H)-ones and forty-five derivatives of 3-phenyl-2H-1,3-benzoxazine-2,4(3H)-dithiones was synthesised. The compounds exhibited in-vitro activity against Mycobacterium tuberculosis, M. kansasii (two strains), and M. avium. The most active derivatives were more active than isonicotinhydrazide (INH). The quantitative relationships between the structure and antimycobacterial activity were calculated. The activity against M. tuberculosis increased with the lipophilicity of the substituents.

Morphometric Differences Between the Phylogeographic Lineages of the Common Hamster Cricetus Cricetus in Poland
As the common hamster is endangered in the European part of its range, it is necessary to define the conservation units for successful management of natural populations. Here we describe the case of clear morphometric differentiation between phylogeographic lineages of the common hamster. The standard external measurements were taken from 209 common hamsters collected during the period 2005-2007 from the present species range in Poland. The studied populations belong to different phylogeographic lineages P3 (Polish Pannonia) and E1, and the hamsters of P3 lineage are smaller with longer feet and tails than the hamsters of E1 lineage. The phylogeographic lineages of the common hamster can be defined as evolutionary significant units (ESU) due to the significant genetic differentiation and as management units (MU) with the evidence for ecological differentiation.

Epimorphosis of Heterosymelic Appendages inTegenaria Atrica(Araneae, Agelenidae)Studies of epimorphic regeneration of appendages were carried out on larvae and nymphs ofTegenaria atricaC.L. Koch with heterosymely (accretion of appendages on the same side of the body) of two walking appendages and of walking appendages with pedipalpi. All the anomalies were obtained by exposing developing embryos to alternate temperatures of 14 and 32°C. Amputation of fragments of anomalous appendages was always followed by regeneration. Based on the characteristic external structures of the regenerating joints, successive stages of epimorphosis were estabilished, whose start and end were marked by ecdyses. Several types of regenerates were found, whose anatomical structure did not undergo further significant changes until the end of our observations.

Seasonal Characterisation and Trends Study of Nutrient Concentrations in Surface Water from Catchments with Intensive Livestock Farming
Temporal changes in observed nitrogen and phosphorus losses to surface water were studied in 3 agricultural catchments in order to evaluate the achievement of water protection targets in Latvia. The aim of this study is to investigate the water quality measures in high density livestock farming catchments. Long-term monitoring data (years 1996-2008) of water quality used in the analysis show a high annual and monthly variability of nutrients. The results demonstrate little or no reduction of nutrient concentrations in surface water. The results suggest that water protection measures for agricultural production need to be further intensified.

Simulation of the Stock of Electric Appliances and Calculation of Standby Losses for Latvia
Standby losses in households are discussed in this paper. As there was no information on the total volume of standby losses in Latvia, the objective of the study was to calculate: the percentage from the household total electricity bill that goes to standby losses; what are the total costs for these losses; and how much CO2 is produced to generate the amount of electricity that is needed to cover these standby losses. All calculations were conducted for one and for all households in Latvia and the results of one household were compared with an average European household. Finally, the savings potential that can be obtained implementing the Eco-design Directive and other political instruments was examined.

Hemp (Cannabis sativa L.) as an Environmentally Friendly Energyplant
Hemp is suitable as a renewable energy resource. The aim of this study was to clarify local hemp's (Cannabis sativa L.) possibilities for energy use. Arsenic (As), cadmium (Cd), lead (Pb) and titanium (Ti) presence in hemp was determined using an inductively coupled plasma optical emission spectrometer Optima 2100 DV. If there were increased N fertilizer rates, there were increased hemp ‘Pūriņi’ seeds and shive yield increases, but the oil content was reduced. Arsenic content was higher in the shives than in the stems with fibre. The ash content depends on non-organic substances which the plants absorb during the vegetation season. The lignin content depends on several factors: plant parts, and the N fertilizer rate. The unexplored factors have a great effect on the ash and lignin content. Hemp is suitable for cultivation and for bio-energy production in the agro-climatic conditions in Latvia.

Modeling of the Thermodynamic Properties of Liquid Fe-Ni and Fe-Co Alloys From the Surface Tension DataRecently proposed method of modeling of thermodynamic properties of liquid binary alloys from their surface tension data is described. The method utilizes Melford and Hoar equation, relating surface tension with excess Gibbs free energy, combined with new description of the monatomic surface layer and β parameter. The method is tested on Fe-Ni and Fe-Co alloys and the obtained results show very good agreement with experimental thermodynamic data of other authors. The model allows also to calculate the surface tension from thermodynamic data, and it gives better agreement with experimental results than those modeled with the use of Butler equation and traditionally defined monatomic surface layer and β = 0.83.

Biological activity of the red algaLaurencia brandeniiThe marine red algaLaurencia brandeniicollected from the southwest coast of India (Indian Ocean) was extracted and fractioned using column chromatography. The individual fractions were evaluatedin vitrovia antimicrobial activity against six species of Microbial Type Culture Collection and three species of clinical human pathogens, antipest activity onSitophilus oryzae, maggoticidal activity against 2ndinstar larvae ofSarcophagasp. and termiticidal activity againstMicrotermes obesi.It was found that the fraction eluted using petroleum ether:chloroform (6:4) exhibited broader biological activities. The phyco-constituents of the active fraction were identified by gas chromatography-mass spectrometry (GC-MS) analysis. The GC-MS profile of the active fraction revealed that the main constituent was octadecadienoic acid (49.75%) followed by n-hexadecanoic acid (14.24%), which might have a functional role in the biological activities. The overall activity profile envisages that these bioactive compounds fromL. brandeniicould be utilized as a renewable natural resource for the development of novel environmental-compatible formulations for the control of human pathogens, pests, termites and maggots.

Preliminary Ecotoxicity and Biodegradability Assessment of Metalworking Fluids
The main aim of this study was to evaluate the potential of activated sludge from sewage treatment plant to degrade selected MWFs (ecotoxicity to bacterial consortium) and to evaluate the ecotoxicity by Lemna minor-higher plant. After evaluating the ecotoxicity, biodegradations rate with activated sludge was assessed on the basis of COD measurement. Preliminary study of measuring the ecotoxicity according to OECD 221 by Lemna minor shows effective concentration of Emulzin H at the rate of 81.6 mg l-1, for Ecocool 82.9 mg l-1, for BC 25 about 99.3 mg l-1, and for Dasnobor about 97.3 mg l-1. Preliminary study of measuring the ecotoxicity by bacterial consortium according to OECD 209 (STN EN ISO 8192) shows effective concentration of Blasocut BC 25 at the rate 227.4 mg l-1. According to OECD 302B, the biodegradations level of Emulzin H, Ecocool and BC 25 achieved 80% in 10 days. It can be stated that these MWFs have potential to ultimate degradation, but the statement has to be confirmed by a biodegradability test with other parameters than COD, which exhibits some disadvantages in testing O/W emulsions.

The Study Into the Ceramic-to-Metal Soldered Joints Interface for Al2O3 and SiO2 Materials
The conditions of joining a ceramic-metal configuration by active metal soldering using tin-based (SnTi3) alloys are presented. Active metal (Ti) was alloyed in a low concentration of 3 weight percent. The joining process was carried out in a vacuum (10-2 Pa) at a peak temperature of 860 °C with a short holding period (t = 9 min). The ceramic-metal soldered interface was examined using optical microscopy, scanning and transmission electron microscopy (SEM, TEM). The natures of the interfacial reactions and the reaction products were identified using X-ray diffraction (XRD). The thickness of reaction layers and X-ray maps of the same region were measured.

Object
Technical improvements in commercially available radiosurgery platforms have made it practical to treat a large number of intracranial targets. The goal of this study was to investigate whether the dose to normal brain when planning radiosurgery to multiple targets is apparatus dependent.

Methods
The authors selected a single case involving a patient with 12 metastatic lesions widely distributed throughout the brain as visualized on contrast-enhanced CT. Target volumes and critical normal structures were delineated with Leksell Gamma Knife Perfexion software. The imaging studies including the delineated contours were digitally exported into the CyberKnife and Novalis multileaf collimator–based planning systems for treatment planning using identical target dose goals and dose-volume constraints. Subsets of target combinations (3, 6, 9, or 12 targets) were planned separately to investigate the relationship of number of targets and radiosurgery platform to the dose to normal brain.

Results
Despite similar target dose coverage and dose to normal structures, the dose to normal brain was strongly apparatus dependent. A nonlinear increase in dose to normal brain volumes with increasing number of targets was also noted.

Conclusions
The dose delivered to normal brain is strongly dependent on the radiosurgery platform. How general this conclusion is and whether apparatus-dependent differences are related to differences in hardware design or differences in dose-planning algorithms deserve further investigation.
