Effects of Iron Supplementation on Erythropoietic Response in Patients with Cancer-Associated Anemia Treated by Means of Erythropoietic Stimulating Agents
Authors: Karlsson Torbjörn
Published: October 2011

During the past decade, intravenous iron supplementation to ESA (erythropoiesis-stimulating agent) therapy has emerged as an option to augment hemoglobin response in anemic cancer patients. In this paper, the results of seven published randomized clinical trials assessing the role of iron supplementation to ESA therapy in the hematology/oncology setting will be discussed. The pathogenetic mechanisms behind functional iron deficiency, a major reason for ESA hyporesponsiveness in cancer, will also be described.
Toxicology Evaluation of Realgar-Containing Niu-Huang-Jie-Du Pian as Compared to Arsenicals in Cell Cultures and in Mice
Authors: Miao Jia-Wei , Liang Shi-Xia , Wu Qin , Liu Jie , Sun An-Sheng
Published: October 2011

Niu-Huang-Jie-Du Pian (NHJD) is a widely used traditional Chinese medicine containing realgar (As4S4). Realgar has been included in many traditional medicines, but is often taken as arsenite for risk assessment. To evaluate true risk of realgar and realgar-containing NHJD, their toxicity was compared with common arsenicals. In cultured cells, the LC50 for NHJD (1200 μM) and realgar (2000 μM) was much higher than arsenite(35 μM), arsenic trioxide (280 μM), and arsenate (400 μM). Acute toxicity in mice showed more severe liver and kidney injury after arsenite or arsenate, but was mild after realgar and NHJD, corresponding to cellular and tissue arsenic accumulation. The expressions of arsenic-sensitive stress gene metallothionein-1 were increased 3–7-folds after arsenite or arsenate, but were unaltered after NHJD and realgar. Thus, realgar and NHJD are much less toxic than arsenite and arsenate. The use of total arsenic to evaluate the safety of realgar and realgar-containing NHJD is inappropriate.
Numerical Study on Pressure Fluctuations Reduction in Centrifugal Pumps: Influence of Radial Gap and Splitter Blades
Authors: Solis Moisés , Bakir Farid , Khelladi Sofiane , Noguera Ricardo
Published: October 2011

Numerical study was carried out in four centrifugal pumps to analyze the effects of
adding splitters and incrementing the radial gap in order to decrease the pressure
fluctuations at the blade passage frequency. It is well known that in this kind of pump,
the interactions between the flow leaving the impeller and entering the volute
generate fluctuating pressures which propagate toward the inlet and the discharge of
the pump. These pulsations are mainly associated to the blade passage frequency
presenting high amplitudes near the volute tongue and at impeller discharge. Four
configurations were analyzed using numerical simulations; the first is the reference
pump which will be optimized and the others are the optimized ones. The numerical
modelling was performed at the same flow rate having to vary in some cases the
rotational speed to reach the operating point. During the calculations, the pressure
signals were recorded by virtual sensors placed at several locations of the pump then
they were analyzed and processed by means of the Fast Fourier Transform. The
pressure fluctuations were plotted and compared between the four configurations,
showing clearly the fact of varying the blades number and the radial gap influence
significantly on their reduction.
Consensus Statement on Effective Communication of Urgent Diagnoses and Significant, Unexpected Diagnoses in Surgical Pathology and Cytopathology From the College of American Pathologists and Association of Directors of Anatomic and Surgical Pathology

Context.—Recognizing the difficulty in applying the concept of critical values to anatomic pathology diagnoses, the College of American Pathologists and the Association of Directors of Anatomic and Surgical Pathology have chosen to reevaluate the concept of critical diagnoses.

Objective.—To promote effective communication of urgent and significant, unexpected diagnoses in surgical pathology and cytology.

Design.—A comprehensive literature search was conducted and reviewed by an expert panel.

Results.—A policy of effective communication of important results in surgical pathology and cytology is desirable to enhance patient safety and to address multiple regulatory requirements.

Conclusions.—Each institution should create its own policy regarding urgent diagnoses and significant, unexpected diagnoses in anatomic pathology. This policy should be separate from critical results or panic-value policies in clinical pathology, with the expectation of a different time frame for communication. Urgent diagnosis is defined as a medical condition that, in most cases, should be addressed as soon as possible. Significant, unexpected diagnosis is defined as a medical condition that is clinically unusual or unforeseen and should be addressed at some point in the patient's course. Further details of this statement are provided.
Barium
Authors: Boffito Claudio
Published: October 2011

Barium belongs to Group 2(IIA) of the Perioidic Table. In its natural form, barium never occurs as the metal because of its reactivity, but is almost always found as the ore barite. China and India account for 70% of the world's barite supplies. Barium metal is produced by the reduction of barium oxide with a less nonvolatile element, usually aluminum. Barium's economic information is based on barite. Barite is used in the oil and gas drilling industries where it is used to make drilling mud. Barium metal reacts with water and acids. Contact with skin causes irritation and possible corrosive damage. Barium occurs in seawater . The terrestrial abundance of barium is ∼ 250 g/t. The major use of barium is the production of barium‐aluminum alloy‐evaporation getters (gas absorbers) in CRTs for television sets and computer monitors. It is also used to improve performance of lead alloys grids of acid batteries and in barium‐nickel alloys for spark plug electrodes and in vacuum tubes.
Beryllium and Beryllium Alloys and Composities
Authors: Kaczynski Donald J.
Published: October 2011

Beryllium is the only light metal having a high melting point. Although 45 beryllium‐containing minerals have been identified, only beryl and bertrandite are of commercial significance. Brush Resources Inc.,operating in Utah, is the one U.S. company that mines bertrandite ore, which is converted along with imported beryl and beryl from the U.S. National Defense Stockpile into beryllium hydroxide. The majority of beryllium commercially used is in alloys, principally copper‐beryllium alloys. The uses of unalloyed beryllium is based on its nuclear and thermal properties and its unique stiffness. Beryllium oxide ceramics are important because of very high thermal conductivity of the oxide while also serving as an electrical insulator. Beryllium's reactivity limits its use in the formulation of composite materials. There are only two available: beryllium‐aluminum and beryllium‐beryllium oxide. A small amount of beryllium produces strong effects in several base metals. In copper and nickel, this alloying element promotes strengthening through precipitation hardening. In aluminum alloys, a small addition improves oxidation resistance, castability, and workability.Beryllium, beryllium‐containing alloys, and beryllium oxide ceramics can be recycled.
Sodium Chloride
Authors: Feldman Susan R.
Published: October 2011

The electrolyte, sodium chloride, NaCl, is commonly known as salt. It is readily available and inexpensive. A basic requirement for life, it is found throughout the earth in natural underground deposits.as the mineral halite and as mixed evaporates in saline lakes. Salt is the largest component of dissolved solids found in seawater. Underground deposits are found throughout the world. Producers of salt classify their output by the three methods used for its production: mechanical evaporation of solution‐mined brine, such as evaporated‐granulated salt; underground mining of halite deposits, ie, rock salt; and solar evaporation of seawater, natural brine, or solution‐mined brine such as solar salt. Salt in solution is a fourth classification, ie, solution‐mined brine typically used for feedstock for chemical production. Salt is consumed by most of the world's population and a minimum intake of 500 mg/day is needed to sustain health. However, there are populations that need to restrict their intake because of health issues such as hypertension. Over 14,000 uses of salt have been identified The salt industry generally classifies salt uses by five principal categories and lumps the remaining in the miscellaneous category. Uses are as follows: 1, chemical, 2, highway deicing and stabilization;3, food use and processing; 4, agriculture; 5, water conditioning; and 6, miscellaneous

Y3−xErxAl5O12 Aluminate Ceramics: Preparation, Thermal Properties and Theoretical Model of Thermal Conductivity
Authors: Liu Yan‐Gai , Peng Peng , Fang Minghao , Huang Zhaohui
Published: October 2011

Rare‐earth aluminate ceramics for thermal‐barrier coatings (TBCs) are synthesized. The Young's modulus and thermal properties decrease with erbium additive increasing. The Y3−xErxAl5O12 ceramics (x = 1, 3) possess a much‐lower thermal conductivity compared with 8YSZ. The lower Young's modulus and thermal‐expansion coefficient are due to the larger atomic weight of the Er substitutional atom. Additional phonon‐scattering effects also contribute to the lower thermal conductivity. The results indicate that Y3−xErxAl5O12 can be explored as a candidate material for TBC systems. A theoretical model that describes the influence of point defects on the thermal conductivity is discussed.

Authors: Xia Min , Ge Changchun , Guo Hongyan
Published: October 2011

Aligned single‐crystalline β‐Si3N4 whiskers with high aspect ratio were first prepared via a Self‐propagating high temperature‐synthesis (SHS) process, by using tungsten powders as catalysts. The as‐synthesized Si3N4 whiskers typically have uniform diameters of 400 nm, length about 200 µm, and exhibit smooth and straight surfaces. Above all, the products possesses a perfect aligned structure, which is quite different from the reported β‐Si3N4 whiskers. Elastic bending modulus of individual whiskers was measured by in‐situ TEM process, the average value of elastic bending modulus of individual as‐synthesized whiskers was 488 GPa. Results revealed that tungsten powders plays an significant effects on the morphology of Si3N4 whiskers.
Quantum mechanics needs no consciousness
Authors: Yu S. , Nikolić D.
Published: October 2011

It has been suggested that consciousness plays an important role in quantum mechanics as it is necessary for the collapse of wave function during the measurement. Here we formulated several predictions that follow from this hypothetical relationship and that can be empirically tested. Experimental results that are already available suggest falsification of these predictions. Thus, the suggested link between human consciousness and collapse of wave function does not seem viable. We discuss the implications of these conclusions on the role of the human observer for quantum mechanics and on the role of quantum mechanics for the observer's consciousness.
Study and optimization of a soaking treatment to reduce migration from plasticized polyvinyl chloride
Authors: Boussoum M. O. , Belhaneche‐Bensemra N.
Published: October 2011

Commercial sunflower oil was epoxidized, and epoxidized sunflower oil (ESO) was used as a thermal stabilizer for polyvinyl chloride (PVC). This work describes a process capable to reduce the additives migration between plasticized PVC stabilized with ESO and food simulants. For that purpose, samples were first soaked in n‐heptane and then dried. Soaking temperature and drying temperature with time were optimized by using the methodology of experiment plans. The optimal conditions found were applied to study the migration of additives in a fatty simulant (olive oil) at 40°C. The test conditions were 12 days. Twelve circular samples of plasticized PVC were immersed in 120 mL of olive oil. A circular sample and 10 mL of food simulant were taken off every day to be analyzed. The rate of mass variation was followed. The specific migrations of the present additives were investigated by using Fourier transform infrared spectroscopy, atomic absorption spectrometry and gas chromatography‐ mass spectrometry. The results showed that the studied process reduced considerably the additives migration. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2012
Propylene polymerization over MgCl2‐supported TiCl4 catalysts bearing different amounts of a diether internal electron donor: Extrapolation to the role of internal electron donor on active site
Authors: Lu Li , Niu Hui , Dong Jin‐Yong
Published: October 2011

In this work, the composition of MgCl2‐supported Ziegler‐Natta (ZN) catalysts bearing different amounts of 9,9‐bis(methoxymethyl)fluorine (BMMF) and the propylene polymerization over these catalysts are investigated. Based on the experimental results, the models of active sites suitable for ZN catalysts with/without internal donor BMMF are established, and they can be described as follows: atactic site (I)—isolated TiCl4 monomeric species on the (110) lateral cut (around which there is no complexes), weakly isospecific site (II)—semi‐isolated and surrounded TiCl4 monomeric species on the (110) lateral cut (in the vicinity of which BMMF or other TiCl4 is adsorbed), and highly isospecific site (III)—dimeric TiCl4 species (Ti2Cl8) on the (104) lateral cut. Meanwhile, the mechanism underlying the role of BMMF on active sites is revealed (i) convert atactic sites (I) to weakly isospecific site (II) by occupying either or both of L1 or/and L2 vacancies around site; (ii) improve the isotacticity of weakly isospecific site (II) in donor‐free ZN catalyst by adsorbing at L2 vacancy or/and replacing the Cl for TiCl4 at L1; and (iii) replace highly isospecific site (III). In addition, these roles of BMMF are successively achieved according to the amount of BMMF added. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2012

Authors: Ku Sung‐Yu , Hung Wen‐Yi , Chen Chung‐Wen , Yang Shih‐Wei , Mondal Ejabul , Chi Yun , Wong Ken‐Tsung
Published: October 2011

In this study, we synthesized and characterized a series of spirobifluorene‐based bipolar compounds (D2 ACN, DNPACN, DNTACN, and DCzACN) in which a dicyano‐substituted biphenyl branch, linked orthogonally to a donor biphenyl branch bearing various diarylamines, acted as an acceptor unit allowing fine‐tuning of the morphological stability, triplet energy, bipolar transport behavior, and the HOMO and LUMO energy levels. The promising physical properties of these new compounds, together with their ability to transport electrons and holes with balanced mobilities, made them suitable for use as host materials in highly efficient phosphorescent organic light‐emitting diodes (PhOLEDs) with green iridium‐based‐ or red osmium‐based phosphors as the emitting layer (EML). We adopted a multilayer structure to efficiently confine holes and electrons within the EML, thus preventing exciton diffusion and improving device efficiency. The device incorporating D2 ACN doped with the red emitter [Os(bpftz)2(PPhMe2)2] (bpftz=3‐(trifluoromethyl)‐5‐(4‐tert‐butylpyridyl)‐1,2,4‐triazolate) gave a saturated red electrophosphorescence with CIE coordinates of (0.65, 0.35) and remarkably high efficiencies of 20.3 % (21 cd A−1) and 13.5 Lm W−1 at a practical brightness of 1000 cd m−2.
Randomized clinical trial comparing the cost and effectiveness of bipolar vessel sealers versus clips and vascular staplers for laparoscopic colorectal resection
Authors: Adamina M , Champagne B J , Hoffman L , Ermlich M B , Delaney C P
Published: October 2011

Background

The widespread use of laparoscopy has resulted in a variety of instruments being used routinely for vascular control. This randomized controlled trial evaluated the cost-effectiveness of bipolar vessel sealer (BVS) compared with clips and vascular stapler (CVS) in straight laparoscopic colorectal resection.

Methods

Patients scheduled for elective colorectal resection, including benign and malignant diseases, were randomized to either BVS or CVS for vascular control. Patients whose operation was converted to an open approach before pedicle ligation were excluded. The primary endpoints were duration of operation, including time taken to control vascular pedicles, and cost of disposable instruments for vascular control.

Results

Of 114 patients randomized to BVS (60 patients) or CVS (54), 14 did not receive the allocated vascular control device, leaving 55 and 45 respectively for analysis. The BVS reduced the time spent for vascular control by a mean of 6·9 min (P = 0·031) and reduced the cost of disposable instruments for vascular control by US $ 80·7 per patient (P = 0·043). For total colectomy, the BVS reduced the operating time by 103·6 min (P = 0·023) and the time taken for vascular control by 16·8 min (P = 0·022). For left colectomy, it decreased the time to vascular control by 9·3 min (P = 0·021). In multivariable analysis, the cost of disposable instruments for vascular control was independently reduced by randomization to BVS, type of procedure, female sex and estimated blood loss. The mean cost reduction was $ 88·2 for left colectomy (P = 0·037), $ 377·7 (P = 0·005) for total colectomy and $ 366·9 (P = 0·012) for proctectomy. Conversely, use of the BVS increased the cost of instruments used for vascular control in right colectomy by $ 92·6 (P = 0·012).

Conclusion

BVS devices are expedient and cost-efficient in proctectomy, left and total colectomy procedures. Registration number: NCT00487409 (http://www.clinicaltrials.gov).
NHE1 mediates migration and invasion of HeLa cells via regulating the expression and localization of MT1‐MMP
Authors: Lin Yani , Wang Jian , Jin Weina , Wang Lihong , Li Huawen , Ma Li , Li Qinghua , Pang Tianxiang
Published: October 2011

Na+/H+ exchanger 1 (NHE1), acting as an important regulator of intracellular pH (pHi) and extracellular pH (pHe), has been known to play a key role in the metastasis of many solid tumours. However, the exact mechanism underlying these processes, especially in cervical cancer, is still poorly understood. In the current study, we first showed that the inhibition of NHE1 activity by the specific inhibitor cariporide could suppress migration and invasion of HeLa cells in vitro. Moreover, cariporide also reversed the enhanced migration and invasion in HeLa cells by overexpressed membrane‐type 1 matrix metalloproteinase (MT1‐MMP). Subsequently, our results showed that NHE1 regulated the expression of MT1‐MMP at both messenger RNA and protein levels as well as its localization. Meanwhile, we observed slight modification in the morphology of HeLa cell after treating with cariporide. The present work indicates that NHE1 mediates HeLa cell metastasis via regulating the expression and localization of MT1‐MMP and provides a theoretical basis for the development of novel therapeutic strategies targeting cervical cancer.

Knock‐down of HEXA and HEXB genes correlate with the absence of the immunostimulatory function of HSC‐derived dendritic cells
Authors: Tiribuzi Roberto , D'Angelo Francesco , Berardi Anna C. , Martino Sabata , Orlacchio Aldo
Published: October 2011

In an attempt to investigate whether the genetic defect in the HEXA and HEXB genes (which causes the absence of the lysosomal β‐N‐acetyl‐hexosaminidase), are related to the wide inflammation in GM2 gangliosidoses (Tay‐Sachs and Sandhoff disease), we have chosen the dendritic cells (DCs) as a study model. Using the RNA interference approach, we generated an in vitro model of HEXs knock‐down immunogenic DCs (i‐DCs) from CD34+‐haemopoietic stem cells (CD34+‐HSCs), thus mimicking the Tay‐Sachs (HEXA−/−) and Sandhoff (HEXB−/−) cells.

We showed that the absence of β‐N‐acetyl‐hexosaminidase activity does not alter the differentiation of i‐DCs from HSCs, but it is critical for the activation of CD4+T cells because knock‐down of HEXA or HEXB gene causes a loss of function of i‐DCs. Notably, the silencing of the HEXA gene had a stronger immune inhibitory effect, thereby indicating a major involvement of β‐N‐acetyl‐hexosaminidase A isoenzyme within this mechanism.

Pt–Sn/γ‐Al2O3‐Catalyzed Highly Efficient Direct Synthesis of Secondary and Tertiary Amines and Imines
Authors: He Wei , Wang Liandi , Sun Chenglin , Wu Kaikai , He Songbo , Chen Jiping , Wu Ping , Yu Zhengkun
Published: October 2011

Versatile syntheses of secondary and tertiary amines by highly efficient direct N‐alkylation of primary and secondary amines with alcohols or by deaminative self‐coupling of primary amines have been successfully realized by means of a heterogeneous bimetallic Pt–Sn/γ‐Al2O3 catalyst (0.5 wt % Pt, Pt/Sn molar ratio=1:3) through a borrowing‐hydrogen strategy. In the presence of oxygen, imines were also efficiently prepared from the tandem reactions of amines with alcohols or between two primary amines. The proposed mechanism reveals that an alcohol or amine substrate is initially dehydrogenated to an aldehyde/ketone or NH‐imine with concomitant formation of a [PtSn] hydride. Condensation of the aldehyde/ketone species or deamination of the NH‐imine intermediate with another molecule of amine forms an N‐substituted imine which is then reduced to a new amine product by the in‐situ generated [PtSn] hydride under a nitrogen atmosphere or remains unchanged as the final product under an oxygen atmosphere. The Pt–Sn/γ‐Al2O3 catalyst can be easily recycled without Pt metal leaching and has exhibited very high catalytic activity toward a wide range of amine and alcohol substrates, which suggests potential for application in the direct production of secondary and tertiary amines and N‐substituted imines.
