Granulopoiesis-stimulating factors to prevent adverse effects in the treatment of malignant lymphoma.

BACKGROUND Granulopoiesis-stimulating factors (G-CSF and GM-CSF) are being used to prevent febrile neutropenia and infections in the treatment of patients with malignant lymphoma. The question whether G-CSF and GM-CSF improve dose-intensity, tumour response and overall survival in this patient population has not been answered yet. Since the results from single studies are inconclusive a systematic review was required. OBJECTIVES To undertake a systematic review in patients with malignant lymphoma to determine the effectiveness of G-CSF and GM-CSF to prevent neutropenia, febrile neutropenia, infection, improve quality of life, adherence to the treatment protocol, tumour response, freedom from treatment failure (FFTF), overall survival (OS) and to assess adverse events of G-CSF and GM-CSF. SEARCH STRATEGY Medline, Embase, CancerLit, the Cochrane Library and smaller databases, Internet-databases of ongoing trials, conference proceedings of the American Society of Clinical Oncology and the American Society of Hematology were searched. We included full-text and abstract publications as well as unpublished data. SELECTION CRITERIA Randomised controlled trials comparing prophylaxis with G-CSF or GM-CSF versus placebo/no prophylaxis in adult patients with malignant lymphoma undergoing chemotherapy were included in this review. Both study arms had to receive identical chemotherapy and supportive care. DATA COLLECTION AND ANALYSIS Eligibility and quality assessment, data extraction and analysis were done in duplicate. Authors were contacted to obtain missing data. MAIN RESULTS We included 12 eligible studies with 1.823 randomised patients. Compared with no prophylaxis, G-/GM-CSF significantly reduced the relative risk for severe neutropenia (RR 0.67 [95% CI 0.60-0.73]), febrile neutropenia (RR 0.74 [95% CI 0.62-0.89]) and infection (RR 0.74 [95% CI 0.64-0.85]). There was no evidence for G-/GM-CSF to decrease the number of patients who required iv antibiotics (RR 0.82 [95%CI 0.57-1.18]), to reduce infection related mortality (RR 1.37 [95% CI 0.66-2.82]), or to improve complete tumour response (RR 1.02 [95% CI 0.94-1.11]), FFTF (HR 1.11 [95% CI 0.91-1.35]) and OS (HR 1.00 [95% CI 0.86-1.16]). One study evaluated quality of life parameters and did not find differences between the groups. REVIEWER'S CONCLUSIONS G-CSF and GM-CSF, when given prophylactically in patients with malignant lymphoma undergoing conventional chemotherapy, reduce the risk of neutropenia, febrile neutropenia and infection. However, based on the currently available randomised trials in this clinical setting, there is no evidence for G-/GM-CSF to provide a significant advantage in terms of complete tumour response, FFTF and OS.
Salmonella Serovar Identification Using PCR-Based Detection of Gene Presence and Absence

ABSTRACT There are more than 2,500 known Salmonella serovars, and some of these can be further subclassified into groups of strains that differ profoundly in their gene content. We refer to these groups of strains as “genovars. ” A compilation of comparative genomic hybridization data on 291 Salmonella isolates, including 250 S. enterica subspecies I strains from 32 serovars (52 genovars), was used to select a panel of 384 genes whose presence and absence among serovars and genovars was of potential taxonomic value. A subset of 146 genes was used for real-time PCR to successfully identify 12 serovars (16 genovars) in 24 S. enterica strains. A further subset of 64 genes was used to identify 8 serovars (9 genovars) in 12 multiplex PCR mixes on 11 S. enterica strains. These gene panels distinguish all tested S. enterica subspecies I serovars and their known genovars, almost all by two or more informative markers. Thus, a typing methodology based on these predictive genes would generally alert users if there is an error, an unexpected polymorphism, or a potential new genovar.
Characterizing the running patterns of moving target defense mechanisms

Moving Target Defense (MTD) has been proposed as a game-changing theme to increase the work effort to attack as well as the security of target system. There has been proposed a multitude of MTD mechanisms. Generally, these mechanisms follow some fundamental running patterns which determine their functionalities. In this paper, we introduce three main schools of thought on MTD mechanisms systematically and categorize the related works according to them. Then we identify and define three fundamental running patterns exhibited by these MTD mechanisms. Thereafter, we use five MTD mechanisms, which belong to the three schools of thought, as cases to confirm the patterns presented. This work can help the novices of this field to understand the running behaviours of MTDs better and easier, and can also give developers design guidance of new MTD system by providing insights of the running patterns.
Sex differences in animal models of psychiatric disorders

Psychiatric disorders are characterized by sex differences in their prevalence, symptomatology and treatment response. Animal models have been widely employed for the investigation of the neurobiology of such disorders and the discovery of new treatments. However, mostly male animals have been used in preclinical pharmacological studies. In this review, we highlight the need for the inclusion of both male and female animals in experimental studies aiming at gender‐oriented prevention, diagnosis and treatment of psychiatric disorders. We present behavioural findings on sex differences from animal models of depression, anxiety, post‐traumatic stress disorder, substance‐related disorders, obsessive–compulsive disorder, schizophrenia, bipolar disorder and autism. Moreover, when available, we include studies conducted across different stages of the oestrous cycle. By inspection of the relevant literature, it is obvious that robust sex differences exist in models of all psychiatric disorders. However, many times results are conflicting, and no clear conclusion regarding the direction of sex differences and the effect of the oestrous cycle is drawn. Moreover, there is a lack of considerable amount of studies using psychiatric drugs in both male and female animals, in order to evaluate the differential response between the two sexes. Notably, while in most cases animal models successfully mimic drug response in both sexes, test parameters and treatment‐sensitive behavioural indices are not always the same for male and female rodents. Thus, there is an increasing need to validate animal models for both sexes and use standard procedures across different laboratories.
Linking employer labels in recruitment advertising, governance mode and organizational attractiveness

To attract talent, companies might use employer labels (e.g. ‘Great Place to Work’ and ‘ecologically responsible’) in their recruitment advertisements. This study investigates whether the resulting attractiveness of organizations to job candidates might be (1) moderated by the organization’s governance mode (cooperative vs publicly traded) and (2) mediated by candidates’ perceptions of the organization’s prestige and person–organization fit. A survey of 320 respondents shows that, regardless of governance mode, communicating a ‘Great Place to Work’ label improves organizational attractiveness to candidates, by increasing their perceptions of its prestige and person–organization fit. Furthermore, listed companies that communicate this label are more attractive than those that rely on an ‘Ecological’ label.

Post classification smoothing in sub-decimeter resolution images with semi-supervised label propagation

In this paper, we propose a post classification smoothing method aimed at improving the accuracy and visual appearance of sub-decimeter image classification results. Starting from the class confidence maps of a supervised classifier, we find a set of high confidence markers and propagate labels on an extended region adjacency graph. We apply the proposed method on a challenging 5cm resolution dataset over Potsdam, Germany. The proposed algorithm outperforms state-of-the-art post classification smoothing algorithms both when the classifier is trained specifically on the image and when it is trained and tested in different set of images.
Identification of a novel metastasis-suppressor region on human chromosome 12.

There is a critical need for markers that can be used to predict accurately the malignant potential of histological prostate cancers (J. T. Isaacs. Am. J. Pathol., 150: 1511-1521, 1997). Metastasis-suppressor genes are attractive candidates for marker development because, by definition, their loss should be associated with the acquisition of metastatic ability. In an effort to identify such genes, a single copy of human chromosome 12, tagged with the neomycin resistance gene, was introduced into highly metastatic Dunning AT6.1 prostate cancer cells by microcell-mediated chromosomal transfer. Thirty-two AT6.1-12 clonal cell lines were established and the region(s) of chromosome 12 retained was determined by sequence tagged site-based PCR analysis. Representative AT6.1-12 clones containing overlapping regions of chromosome 12 were characterized cytogenetically and were shown to have a normal complement of parental AT6.1 rat chromosomes. Fluorescence in situ hybridization, performed on representative AT6.1-12 hybrids, demonstrated a single human chromosome 12-specific signal. The metastatic ability of six representative clones was tested in immunodeficient mice. All of the AT6.1-12 clones showed the same in vivo growth rates as the control AT6.1-neo cells. Clonal cell lines that contained a conserved approximately 70-cM portion of chromosome 12 (e.g., AT6.1-12-8, -8-1, and -8-3), showed a >30-fold suppression in the number of macroscopic surface lung metastases. Mice that received injections of these cells developed a mean number 4 lung metastases whereas mice that received injections of other AT6.1-12 hybrids (lacking the approximately 70-cM region) or AT6.1-neo control cells, developed a mean number of 140 metastases. Interestingly, histological examination of the lungs of the mice that received injections of AT6.1-12-8 cells showed essentially no microscopic metastases. These findings suggest that a gene(s) encoded by the approximately 70-cM portion of human chromosome 12 suppresses an early step in the metastatic cascade.
Dissociating Orienting Biases From Integration Effects With Eye Movements

Despite decades of research, the conditions under which shifts of attention to prior target locations are facilitated or inhibited remain unknown. This ambiguity is a product of the popular feature discrimination task, in which attentional bias is commonly inferred from the efficiency by which a stimulus feature is discriminated after its location has been repeated or changed. Problematically, these tasks lead to integration effects; effects of target-location repetition appear to depend entirely on whether the target feature or response also repeats, allowing for several possible inferences about orienting bias. To parcel out integration effects and orienting biases, we designed the present experiments to require localized eye movements and manual discrimination responses to serially presented targets with randomly repeating locations. Eye movements revealed consistent biases away from prior target locations. Manual discrimination responses revealed integration effects. These data collectively revealed inhibited reorienting and integration effects, which resolve the ambiguity and reconcile episodic integration and attentional orienting accounts.
Growth Hormone Secretory Status Evaluated by Growth Hormone Peak after Two Pharmacological Growth Hormone Release Stimuli Did Not Significantly Influence the Two-Year Catch-Up Growth Induced by Growth Hormone Therapy in 318 Prepubertal Short Children with Idiopathic Growth Retardation

Background/Aims: In prepubertal short children with idiopathic growth retardation, growth hormone (GH) peak after GH release stimuli classifies patients as growth hormone- deficient (GHD) or non-GHD. This study compared a 2-year growth response to GH therapy in 318 prepubertal short children. Methods: Patients were classified as: severe GHD (GH peaks <5 ng/ml after 2 stimuli; n = 54), mild GHD (GH peaks <10 ng/ml, but one or two between 5 and 10 ng/ml; n = 140), dissociated GH release (GH peak ≧10 ng/ml after 1 stimulus and <10 ng/ml after the other; n = 89), and normal GH release (GH peaks ≧10 ng/ml after 2 stimuli; n = 35). Results: Two-year height gain did not differ statistically among the 4 groups: 1.39 ± 0.51 SD, 16.4 ± 2.3 cm; 1.23 ± 0.56 SD, 15.8 ± 2.1 cm; 1.18 ± 0.53 SD, 15.3 ± 2.0 cm, and 1.14 ± 0.53 SD, 15.4 ± 2.0 cm, respectively, as was also the case for bone age gain: 2.5 ± 0.6, 2.4 ± 0.7, 2.6 ± 0.7 and 2.3 ± 0.5 years, respectively. Conclusions: Our results suggest that GH release stimuli are of little help for deciding on GH therapy in the clinical management of prepubertal short children with idiopathic growth retardation, while well-defined anthropometric and biochemical criteria may be useful.
ANEURYSMS OF THE DISTAL ANTERIOR CEREBRAL ARTERY: RESULTS IN 59 CONSECUTIVELY MANAGED PATIENTS

OBJECTIVEThe aim of this study was to present the clinical and radiological characteristics, surgical management, and outcome in a large series of patients with aneurysms of the distal anterior cerebral artery (DACA) managed in the microsurgical era. METHODSThe records of 1109 patients with anterior circulation aneurysms managed at the authors' institution between 1970 and 1998 were reviewed. RESULTSFifty-nine patients (5.3%) were identified with 67 DACA aneurysms. Seventy-three percent of the patients were women. The mean age of all patients was 47 years. Multiple aneurysms were identified in 51% of all patients, most commonly on the middle cerebral artery. Thirty-six patients had ruptured DACA aneurysms and 23 had unruptured aneurysms. In those with ruptured aneurysms, the admission grade was Grade I in 10 patients (27.8%), Grade II in three patients (8.3%), Grade III in 10 patients (27.8%), Grade IV in seven patients (19.4%), and Grade V in six patients (16.7%). Frontal lobe hematomas occurred in 28% of the patients with ruptured aneurysms and carried a poor prognosis. In those with unruptured aneurysms, 11 were incidental and 12 were identified after a subarachnoid hemorrhage from another aneurysm. The mean diameter was 10 mm in ruptured aneurysms and 5.8 mm in unruptured aneurysms. Fifty-eight patients underwent surgery and one patient was treated with endovascular coiling. Six patients, all with ruptured aneurysms, died. Seventy percent of survivors with ruptured aneurysms had a favorable outcome. CONCLUSIONDACA aneurysms possess a number of characteristics that distinguish them from the more common intracranial aneurysms. With modern neurosurgical and endovascular techniques, an acceptable operative morbidity and mortality can be achieved.
Aural Fullness in M3ni2re's Disease

Objective: Aural fullness in M3ni2re's disease and the predisposing and consequential factors were investigated and possible consequences of aural fullness on participation activity were explored. Methods: 726 subjects of the Finnish M3ni2re Association replied to a questionnaire focusing on symptoms of M3ni2re's disease, sense of coherence, attitude, participation restriction, and general health-related quality of life (EQ-5D). In the analysis, the severity of the disease was controlled. Results: 68% of the subjects had aural fullness and in 37% it was moderate or strong. Aural fullness was rated as the worst problem by 4.4% of the subjects. Females reported more aural fullness than males. Tinnitus, hyperacusis and balance problems were significant predictors of aural fullness. Aural fullness was associated with reduced quality of life and complaints such as vertigo attacks, balance problems and hearing loss. Analysis based on participation restriction indicated that severe aural fullness leads to social isolation. Conclusions: Largely, psychological factors and personal traits modify problems experienced by aural fullness. Relaxation was the only statistically significant method that alleviated aural fullness. i 2014 S. Karger AG, Basel
Structural basis for the neutralization and specificity of Staphylococcal enterotoxin B against its MHC Class II binding site

Staphylococcal enterotoxin (SE) B is among the potent toxins produced by Staphylococcus aureus that cause toxic shock syndrome (TSS), which can result in multi-organ failure and death. Currently, neutralizing antibodies have been shown to be effective immunotherapeutic agents against this toxin, but the structural basis of the neutralizing mechanism is still unknown. In this study, we generated a neutralizing monoclonal antibody, 3E2, against SEB, and analyzed the crystal structure of the SEB-3E2 Fab complex. Crystallographic analysis suggested that the neutralizing epitope overlapped with the MHC II molecule binding site on SEB, and thus 3E2 could inhibit SEB function by preventing interaction with the MHC II molecule. Mutagenesis studies were done on SEB, as well as the related Staphylococcus aureus toxins SEA and SEC. These studies revealed that tyrosine (Y)46 and lysine (K)71 residues of SEB are essential to specific antibody–antigen recognition and neutralization. Substitution of Y at SEA glutamine (Q)49, which corresponds to SEB Y46, increased both 3E2’s binding to SEA in vitro and the neutralization of SEA in vivo. These results suggested that SEB Y46 is responsible for distinguishing SEB from SEA. These findings may be helpful for the development of antibody-based therapy for SEB-induced TSS.
Molecular Dissection of Phage Endolysin

Background: Bacteriophages produce endolysins to hydrolyze host cell wall for their progeny release. Results: Mycobacterium phage endolysin is inactive in E. coli but is active in mycobacteria. Conclusion: An interdomain interaction makes Lysin A inactive in E. coli. Significance: A hydrolase with built-in mechanism attains host specificity. An in-depth study can help in developing strong anti-tuberculosis agents. Mycobacterium tuberculosis has always been recognized as one of the most successful pathogens. Bacteriophages that attack and kill mycobacteria offer an alternate mechanism for the curtailment of this bacterium. Upon infection, mycobacteriophages produce lysins that catalyze cell wall peptidoglycan hydrolysis and mycolic acid layer breakdown of the host resulting in bacterial cell rupture and virus release. The ability to lyse bacterial cells make lysins extremely significant. We report here a detailed molecular dissection of the function and regulation of mycobacteriophage D29 Lysin A. Several truncated versions of Lysin A were constructed, and their activities were analyzed by zymography and by expressing them in both Escherichia coli and Mycobacterium smegmatis. Our experiments establish that Lysin A harbors two catalytically active domains, both of which show E. coli cell lysis upon their expression exclusively in the periplasmic space. However, the expression of only one of these domains and the full-length Lysin A caused M. smegmatis cell lysis. Interestingly, full-length protein remained inactive in E. coli periplasm. Our data suggest that the inactivity is ensued by a C-terminal domain that interacts with the N-terminal domain. This interaction was affirmed by surface plasmon resonance. Our experiments also demonstrate that the C-terminal domain of Lysin A selectively binds to M. tuberculosis and M. smegmatis peptidoglycans. Our methodology of studying E. coli cell lysis by Lysin A and its truncations after expressing these proteins in the bacterial periplasm with the help of signal peptide paves the way for a large scale identification and analysis of such proteins obtained from other bacteriophages.
Two sources of endogenous hydrogen peroxide in Escherichia coli

Mechanisms of hydrogen peroxide generation in Escherichia coli were investigated using a strain lacking scavenging enzymes. Surprisingly, the deletion of many abundant flavoenzymes that are known to autoxidize in vitro did not substantially lessen overall H2O2 formation. However, H2O2 production diminished by 25–30% when NadB turnover was eliminated. The flavin‐dependent desaturating dehydrogenase, NadB uses fumarate as an electron acceptor in anaerobic cells. Experiments showed that aerobic NadB turnover depends upon its oxidation by molecular oxygen, with H2O2 as a product. This reaction appears to be mechanistically adventitious. In contrast, most desaturating dehydrogenases are associated with the respiratory chain and deliver electrons to fumarate anaerobically or oxygen aerobically without the formation of toxic by‐products. Presumably, NadB can persist as an H2O2‐generating enzyme because its flux is limited. The anaerobic respiratory enzyme fumarate reductase uses a flavoprotein subunit that is homologous to NadB and accordingly forms substantial H2O2 upon aeration. This tendency is substantially suppressed by cytochrome oxidase. Thus cytochrome d oxidase, which is prevalent among anaerobes, may diminish intracellular H2O2 formation by the anaerobic respiratory chain, whenever these organisms encounter oxygen. These two examples reveal biochemical and physiological arrangements through which evolution has minimized the rate of intracellular oxidant formation.
Rituximab: review and clinical applications focusing on non-Hodgkin’s lymphoma

Rituximab (Rituxan®) was the first monoclonal antibody approved for cancer therapy and the first single-agent approved for therapy of lymphoma. When combined with CHOP, rituximab is the only drug that has been shown to improve survival of a subpopulation of patients with diffuse large cell lymphoma during the last three decades. It was approved by the FDA for the treatment of patients with relapsed or refractory low-grade or follicular, CD20-positive, B-cell non-Hodgkin’s lymphoma in 1997. Rituximab is also being studied in many other B-cell malignancies alone and in combination with other agents. Furthermore, it is currently being evaluated in several nonmalignant diseases, such as autoimmune disorders. This review will focus on the role of rituximab in patients with non-Hodgkin’s lymphoma.
