SummaryCA125, a tumor marker normally used to follow the clinical course of ovarian cancer, also may have a role in lymphoma. All available series were analyzed using the standard reference value 35 U/ml, but age and sex may influence serum CA125 (sCA125) levels. We aim to study the prognostic value of serum CA125 (sCA125) levels in diffuse large B‐cell lymphoma (DLBCL), considering the influence of age and sex on sCA125 levels. We investigated the relationship between sCA125 and clinical outcome after treatment in 42 patients with DLBCL, comparing both the standard (35 U/ml) and a new age and sex adjusted (sex/age‐adjusted) reference value proposed by our group. We found that patients with elevated sCA125 levels had significantly more adverse prognostic factors at diagnosis, lower CR rates, higher relapse rates and worse survival. In the low‐risk IPI categories, the presence of elevated sCA125 defined a particularly high‐risk subgroup with poorer 3‐year PFS when compared with patients with normal sCA125 levels. The use of a sex/age‐adjusted reference value for sCA125 may increase the sensitivity to identify those patients with elevated sCA125 levels truly related to DLBCL activity.

SummaryThe mean myeloperoxidase index (MPXI) is calculated during the routine complete blood count performed using the autoanalyzer ADVIA120/2120. The pattern of changes in the neutrophil myeloperoxidase levels in patients with specific infectious diseases was analyzed by assessing the MPXI levels. In patients with bacterial sepsis, identified by positive blood‐culture tests, with (n = 29) and without (n = 51) systemic inflammatory response syndrome, the mean MPXI significantly reduced to −3.18 and −2.06, respectively. In contrast, among patients with nontuberculous nonseptic bacterial infections (n = 40), the mean MPXI significantly elevated to 5.51, while tuberculosis patients (n = 37) and patients with viral infection (n = 60) showed an unchanged MPXI (mean values, −0.46 and −1.06, respectively). Among the parameters of inflammation, only the C‐reactive protein values showed a weak correlation with the MPXI levels. [Conclusion] These results indicate that MPXI is correlated with some specific infectious states, i.e. MPXI is low in bacterial sepsis and high in nontuberculous nonseptic bacterial infections. MPXI appears to be an independent and useful biomarker for the diagnosis and follow‐up of infectious diseases, especially when the MPXI values are obtained at regular intervals during the disease courses of the patients.
ORIGINAL ARTICLE: Survival of mutations arising during invasions
Authors: Miller Judith R. 
Published: February 2010

AbstractWhen a neutral mutation arises in an invading population, it quickly either dies out or ‘surfs’, i.e. it comes to occupy almost all the habitat available at its time of origin. Beneficial mutations can also surf, as can deleterious mutations over finite time spans. We develop descriptive statistical models that quantify the relationship between the probability that a mutation will surf and demographic parameters for a cellular automaton model of surfing. We also provide a simple analytic model that performs well at predicting the probability of surfing for neutral and beneficial mutations in one dimension. The results suggest that factors – possibly including even abiotic factors – that promote invasion success may also increase the probability of surfing and associated adaptive genetic change, conditioned on such success.

Avoiding adverse drug reactions to Chinese medicine injections
Authors: Li Tingqian 
Published: February 2010

AbstractA total of 109 varieties of Chinese medicine injections (CMI) have been approved by the State Food and Drug Administration of China, all of which have the potential to induce adverse drug reactions (ADRs). Major ADRs include systemic anaphylaxis, anaphylactic shock, acute intravascular hemolysis, hepatorenal damage, skin lesion, cardiac damage, respiratory system injury, and gastrointestinal disorders. Contributing factors of ADRs include healthcare workers’ inadequate attention to ADRs of CMI, complex ingredients, allergic uncertainties, and inappropriate drug use in children and the aged. To decrease ADRs resulting from CMI, it is essential to improve the selection of drug indications, delivery of proper dosage regimens, compliance with drug instructions, and selection of solvents for the drugs.

Published: February 2010

Abstract Objective To analyze adverse drug reactions (ADRs) associated with Ciwujia injection and possible contributing factors. Methods We searched all clinical studies and ADR reports of Ciwujia injection from the China National Knowledge Infrastructure (CNKI) database. Relevant information such as disease treated; menstruum and compatibility of the Ciwujia injection; age, gender, and allergic history of ADR cases; and the types, occurrence time and severity of the ADRs were collected and analyzed. Results In the 800 clinical studies of Ciwujia injection's efficacy and safety, 97 (12.1%) reported 285 ADR cases. There were 144 ADR reports for the drug describing a total of 236 ADR cases. Most of the ADR reports described cases of anaphylactic shock, while the most common ADR reported in clinical studies was local pain; 27.7% of ADR cases were I to II class in all 521 cases, and four anaphylactic shock cases died. Conclusion The relevant information of ADRs for Ciwujia injection was insufficiently reported in included studies. The ADR type distribution between clinical studies and ADR reports was inconsistency. Most of the reported ADRs were mild, and were treated successfully by slowing down the drip velocity or by withdrawing the drug and treating the symptoms. As Ciwujia injection was one of the highest numbers of ADR reports of traditional Chinese medicine injections, high quality ADR monitoring, standardized ADR reporting, and timely analysis risk factors of ADRs are extremely urgent.
The formation of the Baptistina family by catastrophic disruption: Porous versus non‐porous parent body
Authors: Jutzi Martin , Michel Patrick , Benz Willy , Richardson Derek C. 
Published: February 2010

Abstract— In this paper, we present numerical simulations aimed at reproducing the Baptistina family based on its properties estimated by observations. A previous study by Bottke et al. (2007) indicated that this family is probably at the origin of the K/T impactor, is linked to the CM meteorites and was produced by the disruption of a parent body 170 km in size due to the head‐on impact of a projectile 60 km in size at 3 km s−1. This estimate was based on simulations of fragmentation of non‐porous materials, while the family was assumed to be of C taxonomic type, which is generally interpreted as being formed from a porous body. Using both a model of fragmentation of non‐porous materials, and a model that we developed recently for porous ones, we performed numerical simulations of disruptions aimed at reproducing this family and at analyzing the differences in the outcome between those two models.Our results show that a reasonable match to the estimated size distribution of the real family is produced from the disruption of a porous parent body by the head‐on impact of a projectile 54 km in size at 3 km s−1. Thus, our simulations with a model consistent with the assumed dark type of the family requires a smaller projectile than previously estimated, but the difference remains small enough to not affect the proposed scenario of this family history.We then find that the break‐up of a porous body leads to different outcomes than the disruption of a non‐porous one. The real properties of the Baptistina family still contain large uncertainties, and it remains possible that its formation did not involve the proposed impact conditions. However, the simulations presented here already show some range of outcomes and once the real properties are better constrained, it will be easy to check whether one of them provides a good match.

Abstract
Encapsulation of drugs in intact erythrocytes, because of the profound characteristics of these natural microspheres, has gained considerable attention in recent years. In this study, the inhibition time courses of serum angiotensin-converting enzyme (ACE) activity after intravenous administration of enalaprilat encapsulated in intact erythrocytes was evaluated and compared with free drug, in a rabbit model. Three groups of animals each received free drug, drug-loaded erythrocytes or sham-encapsulated erythrocytes. Serum ACE activity was determined in each case using the synthetic substrate hippuryl-histidyl-leucine and quantitation of the hippuric acid released by a developed and validated HPLC method. The serum ACE inhibition profiles in the three groups showed that the encapsulated drug inhibited the serum ACE more slowly, more efficiently, over a considerably longer time and in a more reproducible manner, than the free drug or sham-encapsulated erythrocytes. We conclude that the erythrocytes can serve as efficacious slow-release drug carriers for enalaprilat in circulation.
Cimetidine: antioxidant and metal-binding properties
Authors: Lambat Zaynab , Limson Janice L , Daya Santy 
Published: February 2010

Abstract
Cimetidine is one of the most potent H2 receptor antagonists for inhibiting excessive histamine-induced acid secretion and is currently used worldwide to treat peptic ulcers. In this study, levels of free radicals were assessed and the ability of cimetidine to act as an antioxidant was determined using nitroblue-tetrazolium assay and lipid peroxidation assays. Free radical generation in the brain is promoted by the presence of iron, as occurs in the Fenton reaction. The results show that cimetidine reduces the generation of superoxide anion formed in the nitroblue-tetrazolium assay. In addition, cimetidine (1 mm) is able to reduce the iron-induced rise in lipid peroxidation in rat brain homogenates. Electrochemistry, UV/Vis spectroscopy and HPLC experiments show metal-ligand interactions between cimetidine and transition metals. The results imply that cimetidine provides a neuroprotective effect by binding to iron and copper, thus making them unavailable for free radical production.
Modified microplex vector enhances transfection of cells in culture while maintaining tumour-selective gene delivery in-vivo
Authors: Dass Crispin R , Burton Mark A 
Published: February 2010

Abstract
A non-commercial liposome (dimethyl dioctadecyl ammonium bromide: dioleoyl phosphatidyl-ethanolamine) was compared with a commercial variety (Lipofectamine) for transfection of cultured rat adenocarcinoma cells and in an in-vivo kidney tumour model. Transfection of the cells in culture and in tumours in-vivo was variable with both types of liposomes. A high-dose microplex (lipoplex–microsphere) vector enhanced liposome-mediated transfection of cells in culture. When these high-dose microplexes were tested in-vivo, they were better than both microspherical and liposomal delivery modes in terms of transgene expression levels and the tumour-to-normal tissue ratio of gene delivery. Microplexes have been demonstrated to be capable of not only selective delivery of plasmids to solid tumours, but also of increasing transfection in cell culture, a finding that may be used in ex-vivo transfection studies. It is hypothesized that microspheres anchored the combination vector closer to the cultured cells, allowing attached liposomes to gain easier access into cells. In-vivo, microspheres permitted the microplexes to selectively deliver their genetic payload within the tumour tissue, from where the action of cationic liposomes on cellular membranes facilitated increased access of plasmids into the cytosol of target cells.
Characterisation and evaluation of novel surfactant bacterial anti-adherent coatings for endotracheal tubes designed for the prevention of ventilator-associated pneumonia

Published: February 2010

Abstract
It is accepted that ventilator-associated pneumonia is a frequent cause of morbidity and mortality in intensive care patients. This study describes the physicochemical properties of novel surfactant coatings of the endotracheal tube and the resistance to microbial adherence of surfactant coated endotracheal tube polyvinylchloride (PVC). Organic solutions of surfactants containing a range of ratios of cholesterol and lecithin (0:100, 25:75, 50:50, 75:25, dissolved in dichloromethane) were prepared and coated onto endotracheal tube PVC using a multiple dip-coating process. Using modulated temperature differential scanning calorimetry it was confirmed that the binary surfactant systems existed as physical mixtures. The surface properties of both surfactant-coated and uncoated PVC., following treatment with either pooled human saliva or phosphate-buffered saline (PBS), were characterised using dynamic contact angle analysis. Following treatment with saliva, the contact angles of PVC decreased; however, those of the coated biomaterials were unaffected, indicating different rates and extents of macromolecular adsorption from saliva onto the coated and uncoated PVC. The advancing and receding contact angles of the surfactant-coated PVC were unaffected by sonication, thereby providing evidence of the durability of the coatings. The cell surface hydrophobicity and zeta potentials of isolates of Staphylococcus aureus and Pseudomonas aeruginosa, following treatment with either saliva or PBS, and their adherence to uncoated and surfactant-coated PVC (that had been pre-treated with saliva) were examined. Adherence of S. aureus and Ps. aeruginosa to surfactant-coated PVC at each successive time period (0.5, 1, 2, 4, 8 h) was significantly lower than to uncoated PVC., the extent of the reduction frequently exceeding 90 %. Interestingly, the microbial anti-adherent properties of the coatings were dependent on the lecithin content. Based on the impressive microbial anti-adherence properties and durability of the surfactant coating on PVC following dip coatings, it is proposed that these systems may usefully reduce the incidence of ventilator-associated pneumonia when employed as luminal coatings of the endotracheal tube.

Published: February 2010

AbstractColon carcinoma cell lines are used widely as screening models for intestinal absorption of drugs. However, the expression of important transport systems and of metabolic enzymes is not completely characterized yet. The expression and inducibility of multidrug resistance gene 1 (MDR1) and cytochrome P450 isoform 3A4 (CYP3A4) was investigated in Caco-2 parental, Caco-2 TC-7 (TC-7) and LS180 cell lines. In the same three cell lines, we investigated the expression of isoforms of the multidrug resistance associated protein family (MRP1–MRP5) and the human pregnane × receptor (hPXR), which may be important for MDR1 and CYP3A4 induction. Cells were treated with rifampicin or 1α, 25-dihydroxycholecalciferol (1,25(OH)2D3) for 72 h and the total RNA was extracted. Afterwards reverse transcription real-time polymerase chain reaction (TaqMan) assay was performed to determine the mRNA expression level. We have shown that in LS180 cells, MDR1 and CYP3A4 were inducible with both inducers. In Caco-2 parental and TC-7 cells, CYP3A4 was only inducible with 1,25(OH)2D3. Furthermore, differences were shown in gene expression of several transport proteins (MDR1 and MRP1–MRP5) and CYP3A4 in different human colon carcinoma derived cell lines. hPXR mRNA was expressed in all three cell lines but the amount of mRNA detected was significantly higher in LS180 cells than in Caco-2 and TC-7 cells. We concluded that LS180 cells were a suitable model to study MDR1 and CYP3A4 induction, but for drug transport studies Caco-2 parental and TC-7 cells would be preferred as the more physiological model.
Efficacy of repifermin (keratinocyte growth factor-2) against abnormalities in gastrointestinal mucosal transport in a murine model of colitis
Authors: Meerveld B Greenwood-Van , Venkova K , Connolly K 
Published: February 2010

AbstractHuman keratinocyte growth factor-2 (KGF-2) is a member of the fibroblast growth factor family that promotes healing of experimental small intestinal ulceration and colitis. The aim of this study was to determine whether repifermin, a truncated form of recombinant human KGF-2, reverses abnormalities in colonic mucosal transport in a murine model of dextran sulfate sodium (DSS)-induced colitis. Male Swiss-Webster mice were given 4% DSS in drinking water for 7 days and then normal drinking water for 3 days. Repifermin (5 mg kg−1, i.p.) or vehicle was administered daily for 7 days starting on Day 4 of DSS exposure. On Day 10, net ion transport was measured electrophysiologically in colonic mucosal sheets. Repifermin significantly reduced DSS-induced colonic inflammation measured by tissue myeloperoxidase activity. Concurrently, in colonic tissue taken from mice treated with repifermin, there was a normalization of basal potential difference and short circuit current, and an improvement in the secretory responses to stimulation of muscarinic and ganglionic cholinoceptors. In control mice, repifermin did not interact directly with colonic epithelial cells or intramural neurones to induce immediate changes in net electrogenic transport. The results suggest that repifermin therapy may improve the mucosal electrogenic transport that is impaired during colitis.

Abstractβ3-Adrenoceptor is the predominant β-adrenoceptor in adipocytes and has drawn much attention during the investigation for anti-obesity and antidiabetes therapeutics. Thirteen new compounds have been evaluated for their potencies and efficacies as β3-adrenoceptor agonists on human β3- adrenoceptor expressed in COS-7 and Chinese hamster ovary (CHO) cells using radio ligand binding assay and cyclic AMP (cAMP) accumulation assay. Phenoxypropanolamine derivatives, SWR-0334NA (([E)-[4-[5-[(3-phenoxy-2-hydroxypropyl)amino]-2-pentene−3-yl] phenoxy]acetic acid sodium salt), SWR-0335SA ((E)-[4-[5-[(3-phenoxy-2-hydroxypropyl)amino]-2-pentene−3-yl] phenoxy] acetic acid ethanedioic acid), SWR-0342SA (S-(Z)-[4-[[1-[2-[(2-hydroxy−3-phenoxypropyl)]amino]ethyl]-1-pro-penyl]phenoxy] acetic acid ethanedioic acid), SWR-0348SA-SITA ((E)-[4-[5-[(3-phenoxy-2-hydroxy-propyl)amino]-2-hexene−3-yl] phenoxy]acetic acid ethanedioic acid) and SWR-0361SA ((E)-N-methyl-[4-[5-[(3-phenoxy-2-hydroxypropyl)amino]-2-pentene−3-yl]phenoxy]acetoamide ethanedioic acid) showed higher agonistic activity for the β3-adrenoceptor. Among the compounds tested, SWR-0334NA exhibited full agonist activity (%Emax = 100.26) despite its lower binding affinity (pK1 = 6.11). Compounds SWR-0338SA((E)-[4-[5-[(2-phenyl-2-hydroxyethyl)amino]-2-pentene−3-yl]phenoxy]acetic acid ethanedioic acid), SWR-0339SA (S-(E)-[4-[5-[(3-phenoxy-2-hydroxypropyl)amino]-2-pentene−3-yl] phenoxy] acetic acid ethanedioic acid), SWR-0345HA ((E)-2-methyl−3-[4-[2-(2-phenyl-2-hydroxyethyl-amino)ethoxy] phenyl]-2-propenoic acid ethyl ester hydrochloride), SWR-0358SA ((E)-(2-methoxy-ethyl)-[4-[5-[(3-phenoxy-2-hydroxypropyl) amino]-2-pentene−3-yl]phenoxy]acetoamide ethanedioic acid) and SWR-0362SA ((E)-1-[[[4-[5-[(3-phenoxy-2-hydroxypropyl)amino]-2-pentene −3-yl]phenoxy]-acetyl]carbonyl]piperidine ethanedioic acid) had moderate agonistic activity and were phenethylamine and phenoxypropanolamine derivatives. Compounds SWR-0065HA ([4-[2-[3-[[(3,4-dihydro-4-oxo-[1,2,4]-triazino(4,5-a)indol)-lyl]oxy]-2-hydroxypropylamino]ethoxy]phenyl]acetic acid methyl ester hydrochloride), SWR-0098NA ((E)-[4-[3-[(2-phenyl-2-hydroxyethyl)amino]-1-butenyl] phenoxy]-acetic acid sodium salt) and SWR-0302HA ([4-[[4-[2-(3-chlorophenoxy-2-hydroxypropyl)amino]-E-2-butenyl]oxy]phenoxy]acetic acid hydrochloride) had very low binding affinity towards β3-adreno-ceptors and they did not induce cAMP accumulation. We concluded that compounds SWR-0334NA, SWR-0335SA, SWR-0342SA, SWR-0348SA-SITA and SWR-0361SA were potential agonists of human β3- adrenoceptor. Further investigation on their selectivity towards β3-adrenoceptor could be useful for the exploration of the physiological properties of the β3-adrenoceptor.

Published: February 2010

AbstractWe investigated the effects of benidipine (hydrochloride), a calcium antagonist, on hydrogen peroxide (H2O2)-induced injury in Langendorff-perfused rat hearts. The hearts were aerobically perfused at a constant flow and exposed to H2O2 (600 μmol L−1) for 4 min, resulting in the oxidative stress-induced myocardial dysfunction (e.g., decrease in the left ventricular developed pressure) and myocardial cell injury (e.g., increase in the release of lactate dehydrogenase). Pretreatment of the hearts with benidipine or nifedipine was performed for 20 min until the start of H2O2 exposure. Benidipine at 1 nmol L−1 and nifedipine at 10 nmol L−1 decreased the myocardial contractility and perfusion pressure to a similar degree in the hearts under normal conditions. Benidipine (1 nmol L−1) significantly reduced the H2O2-induced myocardial damage. Nifedipine (10 nmol L−1) also tended to exhibit similar effects. Benidipine inhibited the increase in tissue lipid peroxidation induced by H2O2. The results suggest that, in addition to the calcium antagonism, benidipine possesses other actions responsible for the cardioprotective effects, to which the antioxidant activity of benidipine may partly contribute.
