Vaccination of Mixed and Full‐Sib Families of Channel Catfish Ictalurus punctatus Against Enteric Septicemia of Catfish With a Live Attenuated Edwardsiella ictaluri Isolate (RE‐33) (2000)

Abstract These studies were conducted to evaluate the efficacy of a live attenuated Edwardsiella ictaluri vaccine against enteric septicemia of catfish. In one study channel catfish fingerlings (72 d of age post hatch) were immersed for 30 min in water containing E. ictaluri RE‐33 at dosages of 1 × 10 6 , 1 × 10 7 and 2 × 10 7 CFU/ML of water. No mortalities were observed following vaccination. Following exposure to virulent Edwardsiella ictaluri the cumulative mortality of fish vaccinated with dosages of at least 1 × 10 7 CFU/mL were significantly lower than that of non‐vacccinated fish in both laboratory and field challenges. Vaccination with 1 × 10 6 CFU RE‐33mL provided some protection during the laboratory challenge but failed to protect fish under field conditions. In a second study, vaccination of 6 full‐sib families of channel catfish at a vaccine dosage of 1 × 10 7 CFU/mL resulted in a relative percent survival among families ranging from 67.1 to 100%. Significant differences in mortality were found among families and between vaccinated and unvaccinated groups, but there was no family by vaccine interaction. Families with the highest mortality after vaccination were also shown to have the highest mortality without vaccination (r = 0.82; P = 0.04).
Integration of global SNP-based mapping and expression arrays reveals key regions, mechanisms, and genes important in the pathogenesis of multiple myeloma (2006)

Multiple myeloma is characterized by genomic alterations frequently involving gains and losses of chromosomes. Single nucleotide polymorphism (SNP)-based mapping arrays allow the identification of copy number changes at the sub-megabase level and the identification of loss of heterozygosity (LOH) due to monosomy and uniparental disomy (UPD). We have found that SNP-based mapping array data and fluorescence in situ hybridization (FISH) copy number data correlated well, making the technique robust as a tool to investigate myeloma genomics. The most frequently identified alterations are located at 1p, 1q, 6q, 8p, 13, and 16q. LOH is found in these large regions and also in smaller regions throughout the genome with a median size of 1 Mb. We have identified that UPD is prevalent in myeloma and occurs through a number of mechanisms including mitotic nondisjunction and mitotic recombination. For the first time in myeloma, integration of mapping and expression data has allowed us to reduce the complexity of standard gene expression data and identify candidate genes important in both the transition from normal to monoclonal gammopathy of unknown significance (MGUS) to myeloma and in different subgroups within myeloma. We have documented these genes, providing a focus for further studies to identify and characterize those that are key in the pathogenesis of myeloma.
HLA Class Ib Molecules and Immune Cells in Pregnancy and Preeclampsia (2014)

Despite decades of research, the highly prevalent pregnancy complication preeclampsia, "the disease of theories," has remained an enigma. Indeed, the etiology of preeclampsia is largely unknown. A compiling amount of studies indicates that the pathological basis involves a complex array of genetic predisposition and immunological maladaptation, and that a contribution from the mother, the father, and the fetus is likely to be important. The Human Leukocyte Antigen (HLA)-G is an increasing focus of research in relation to preeclampsia. The HLA-G molecule is primarily expressed by the extravillous trophoblast cells lining the placenta together with the two other HLA class Ib molecules, HLA-E and HLA-F. Soluble isoforms of HLA-G have been detected in the early endometrium, the matured cumulus-oocyte complex, maternal blood of pregnant women, in umbilical cord blood, and lately, in seminal plasma. HLA-G is believed to be involved in modulating immune responses in the context of vascular remodeling during pregnancy as well as in dampening potential harmful immune attacks raised against the semi-allogeneic fetus. In addition, HLA-G genetic variants are associated with both membrane-bound and soluble forms of HLA-G, and, in some studies, with preeclampsia. In this review, a genetic contribution from the mother, the father, and the fetus, together with the presence and function of various immune cells of relevance in pregnancy are reviewed in relation to HLA-G and preeclampsia.
High-power, narrow-linewidth, stable single-mode hybrid laser (1994)

High-power, narrow-linewidth single-mode lasers have many applications in lightwave systems, particularly as sources in externally modulated communications systems. The ability to produce these devices with a t ightly controlled operating wavelength is very important.
Endocrine Environment of Benign Prostatic Hyperplasia: Prostate Size and Volume are Correlated with Serum Estrogen Concentration (1995)

Estrogen plays an important role in the development of benign prostatic hyperplasia (BPH), as has been shown in both experimental and clinical studies. T determine the endocrine environment of BPH, serum total testosterone (Total-T), free testosterone (Free-T), and estradiol (E2) conceptions were measured, and the relationship between these levels and prostate size and volume was analyzed. Blood samples were collected from subjects who attended the mass screening for prostate disease performed by our institute. No significant correlations were found between Total-T levels, Free-T levels, and prostate size, as determined by digital rectal examination. However, E2 levels and the ratios for E2 levels and the ratios for E2/Total-T and E2/Free-T were significantly correlated with prostate size. To confirm these relationships, prostate volume was calculated from transrectal ultrasonographic images. E2 levels and these two ratios were, indeed, highly correlated with prostate volume. These results suggest that an estrogen-dominant environment plays an important role in the development of BPH.
Vincristine-resistant erythroleukemia cell line has marked increased sensitivity to hexamethylenebisacetamide-induced differentiation. (1988)

Hexamethylenebisacetamide (HMBA)-induced murine erythroleukemia (MEL) differentiation is a multistep process. Commitment is the capacity to express terminal cell division and characteristics of the differentiated phenotype even after the cells are removed from culture with inducer. Culture of MEL cell line 745A.DS19 (DS19) with HMBA causes commitment to terminal differentiation after a latent period of about 10-12 hr. Previous studies have shown that during this latent period, HMBA causes a number of metabolic changes, including modulation in expression of certain protooncogenes. We now report the development of a MEL cell line (designated V3.17) derived from DS19 that is resistant to vincristine and is (i) markedly more sensitive to HMBA, (ii) induced to commitment without a detectable latent period, and (iii) resistant to the effects of phorbol ester and dexamethasone, which are potent inhibitors of HMBA-mediated DS19 differentiation. We suggest that this V3.17 MEL cell line may express a factor that circumvents HMBA-mediated early events, which prepare the cells for commitment to terminal differentiation.
A novel tracking technique for the continuous precise measurement of tumour positions in conformal radiotherapy (2000)

Changing tumour positions induced by organ motion can impede the full exploitation of the strengths of conformal radiotherapy. The unnecessary irradiation of healthy tissue surrounding the target volume can be the consequence. To overcome this, one should measure tumour positions directly and continuously with high resolution in space and time. We have developed a novel tracking technique which will allow this. The method can also be used to survey and monitor the patient positioning. The proper functioning of our method has been technically demonstrated at PSI with the help of phantom irradiation with protons. Implementation into the clinical environment is now beginning.
Expression of activin subunits, activin receptors and follistatin in postimplantation mouse embryos suggests specific developmental functions for different activins (1994)

Using in situ hybridization we have studied the localization of the messenger RNAs encoding the inhibin/activin subunits (alpha, beta A, beta B), the activin-binding protein follistatin and activin receptors (IIA, IIB) in mouse embryos during postimplantation development. From 6.5- to 9.5-days post coitum (p.c.) activin beta A and beta B subunit expression was restricted to the decidua, while activin receptor type IIB messages were exclusively detected in the embryo. Expression of activin receptor type IIA was apparent in the embryo as early as 9.5 days p.c. In contrast, follistatin transcripts were present in both the decidua and the embryo at the early postimplantation stages. In particular, the primitive streak region, specific rhombomeres in the developing hindbrain, somites, paraxial mesoderm and parietal endoderm cells attached to the Reichert's membrane showed strong expression of follistatin. In 10.5- and 12.5-day embryos expression of the beta A subunit message was abundant in mesenchymal tissue, in particular in the developing face, the body wall, the heart, precartilage condensations in the limb and in the mesenchyme of structures that show both epithelial and mesenchymal components, including tissues of the embryonic digestive, respiratory and genital tracts. The distribution of beta B transcripts was quite different from that observed for beta A. beta B is strongly expressed in selected regions of the brain, in particular the fore- and hindbrain, and in the spinal cord. Specific hybridization signals were also present in the epithelium of the stomach and oesophagus. Common sites of beta A and beta B expression are blood vessels, intervertebral disc anlagen, mesenchymal condensations in the flank region and the gonad primordium. The latter organ is the only site in the embryo where the alpha subunit is expressed, and thus where inhibit activity may be present. During the period of organogenesis the sites of expression of activin receptors type IIA and IIB messenger RNA (mRNA) generally coincide with or are adjacent to the sites of beta subunit expression. Differences in the expression patterns of the receptor RNAs are the whisker follicles, where type IIA is expressed, and the metanephros and the forebrain where type IIB transcripts are present. Taken together, the present data suggest that follistatin, but not one of the known activin forms (A,B,AB) is involved in early postimplantation development.(ABSTRACT TRUNCATED AT 400 WORDS)
Clinical toxicities encountered with paclitaxel (Taxol). (1993)

Although paclitaxel (TAXOL) appears to be one of the most promising antineoplastic agents of the last decade, with demonstrated activity in advanced and refractory ovarian, breast, lung, and head and neck cancers, most clinical oncologists have had little experience with the agent. This is largely the result of the initially limited supply of paclitaxel and other obstacles encountered during early clinical development that restricted the drug's availability to a few investigational centers. Although a high incidence of major hypersensitivity reactions due to the Cremophor EL vehicle used in formulation disrupted and almost terminated the clinical development of paclitaxel, hypersensitivity reactions are no longer a serious problem consequent to the advent of effective premedication regimens and longer administration schemes. Instead, neutropenia is the principal toxicity of paclitaxel. At clinically relevant doses, absolute neutrophil count nadirs are severely depressed in most patients. The duration of severe neutropenia, however, is usually brief; treatment delays for unresolved hematologic toxicity are rare, and absolute neutrophil count nadirs are constant with repetitive dosing, suggesting that neutropenia is not cumulative. Asymptomatic sinus bradycardia has occurred in up to 29% of patients in phase II trials, and other cardiac disturbances, including atrioventricular conduction and bundle branch blocks, ventricular tachycardia, and possible ischemic manifestations, have been reported in approximately 3% of patients. Cardiac disturbances have primarily been noted in studies that used cardiac monitoring to more effectively detect and manage major hypersensitivity reactions. Although sinus bradycardia and conduction blocks appear to represent true toxicities, ventricular tachycardia and ischemic manifestations, which have largely been observed in patients with preexisting cardiac disease, may not be due to paclitaxel. In view of the lack of clinical significance of the cardiac effects and their infrequent occurrence, cardiac monitoring during paclitaxel is not recommended for patients without cardiac risk factors. However, until precise risk factors can be defined, patients with a significant antecedent cardiac history are generally not considered to be good candidates for paclitaxel therapy. Neurotoxicity, characterized principally by peripheral neurosensory manifestations, has generally been of mild to moderate severity, even in heavily pretreated patients at paclitaxel doses < or = 200 mg/m2. However, some patients have developed a severe sensory-motor polyneuropathy at higher doses of paclitaxel (given as a single agent or in combination with cisplatin). Patients with an antecedent peripheral neuropathy or coexisting medical illnesses associated with peripheral neuropathy (such as diabetes mellitus and substantial prior alcohol use) appear to be especially prone to developing peripheral neuropathy.(ABSTRACT TRUNCATED AT 400 WORDS)
Correlations for damage in diffused-junction InP solar cells induced by electron and proton irradiation (1997)

The damage to diffused-junction n+-p InP solar cells induced by electron and proton irradiations over a wide range of energy from 0.5 to 3 MeV and 0.015 to 20 MeV, respectively, has been examined. The experimental electron and proton damage coefficients have been analyzed in terms of displacement damage dose, which is the product of the particle fluence and the calculated nonionizing energy loss [G. P. Summers, E. A. Burke, R. Shapiro, S. R. Messenger, and R. J. Walters, IEEE Trans. Nucl. Sci. 40, 1300 (1993).] Degradation of InP cells due to irradiation with electrons and protons with energies of more than 0.5 MeV show a single curve as a function of displacement damage dose. Based on the deep-level transient spectroscopy analysis, damage equivalence between electron and proton irradiation is discussed. InP solar cells are confirmed to be substantially more radiation resistant than Si and GaAs-on-Ge cells.
The Pathophysiology and Treatment of Sepsis (2003)

Sepsis is the leading cause of death in critically ill patients in the United States. Yet the individual host response to septicemia is variable, depending on the patient's immune response, age, nutritional status, and coexisting conditions, as well as on the virulence of the organism and the size of the inoculum. This review examines evolving concepts of sepsis and discusses new and potential therapies. Recent clinical advances include therapy with activated protein C, stringent control of blood glucose, and early goal-directed therapy to treat cellular oxygen deficit. Future therapies may be focused on modulating the immune response in the light of the characteristics of the specific pathogen, the genetic profile of the patient, and the duration of the disease.
Influence of pre- or intraoperational use of tramadol (preemptive or preventive analgesia) on tramadol requirement in the early postoperative period. (2003)

The aim of this study was to assess the influence of iv tramadol on opioid requirement in the early postoperative period. The subjects were 90 patients scheduled for colon surgery (hemicolectomy) who received general anesthesia using the (N2O/O2) isoflurane technique. Thirty patients (group I) were administered 100 mg of tramadol iv before induction of general anesthesia (preemptive analgesia). Group II (30 patients) was administered 100 mg of tramadol iv immediately after peritoneal closure (preventive analgesia) and control group (30 patients) received 100 mg of tramadol iv immediately after operation. Following the operation, all patients were administered tramadol in the PCA-iv mode in order to treat postoperative pain. In the postoperative period, the following parameters were measured: pain intensity (using VAS), total consumption of tramadol, time until the first PCA activation, and frequency of side effects (drowsiness, nausea, vomiting). In patients of groups I and II who had received preemptive or preventive analgesia, a significantly lower total consumption of tramadol, as compared with control group, was observed in the early postoperative period. However, the time until the first PCA activation was significantly shorter in group I as compared to the other two groups. No significant differences between the groups were found regarding pain intensity and frequency of side effects.
Group-specific differentiation between high- and low-risk human papillomavirus genotypes by general primer-mediated PCR and two cocktails of oligonucleotide probes (1995)

In recent years, general primer-mediated PCR assays have been developed to detect a broad spectrum of human papillomavirus (HPV) genotypes. In this study, a procedure enabling a simple group-specific differentiation of high-risk (HPV-16, -18, -31, -33, -35, -39, -45, -51, -52, -54, -56, and -58) and low risk (HPV-6, -11, -34, -40, -42, -43, and 44) HPVs following an HPV general primer-mediated (GP5+/GP6+) PCR is presented. By computer-assisted sequence analysis, oligonucleotides (30-mers) specific for 19 different HPV genotypes were selected from the internal part of the 150-bp GP5+/GP6(+)-amplified region. These oligo probes were tested for specificity in a Southern blot analysis of PCR products derived from the same panel of HPV types. No cross-hybridizations were found. The sensitivities of the oligo probes varied from the femtogram level for the well-amplified HPV types like HPV-16 and -18 to the picogram level for the less-well amplified HPV types like HPV-39 and -51. These sensitivities were reached when the oligo probes were applied both individually and in a cocktail. On the basis of these results, two cocktail oligo probes that enabled a specific and sensitive differentiation between low- and high-risk HPV types were composed.
Glycosylation to Adapt to Stress (2012)

Cancer cells may cope with oxidative stress through the glycosylation of a metabolic enzyme.
Cytochrome P450 CYP3A in human renal cell cancer (1999)

Renal cell cancer is the main malignant tumour of the kidney and has an increasing incidence. This type of tumour has a poor prognosis and shows intrinsic resistance to several anti-cancer drugs. The CYP3A P450 family, which consists of three closely related forms, is involved in the oxidative activation and deactivation of a variety of carcinogens and several anti-cancer drugs. In this study the presence and cellular localization of CYP3A has been investigated using a combination of immunohistochemistry, immunoblotting and reverse transcriptase polymerase chain reaction (RT-PCR) in renal cell cancer and corresponding normal kidney. CYP3A was consistently expressed in both renal call cancer and in normal kidney. In renal cell cancer, CYP3A was localized to tumour cells and in normal kidney the predominant cellular localization of CYP3A was to proximal tubular epithelial cells. RT-PCR showed that both CYP3A5 mRNA and CYP3A7 mRNA were consistently present in both tumour and normal samples, while CYP3A4 mRNA was present in 65% of tumours and 90% of normal samples. This study indicates that individual members of the CYP3A family are expressed in renal cell cancer. The presence of CYP3A in renal cell cancer might be important in the metabolic potentiation as well as the detoxification of chemotherapeutic agents used to renal cancer.
Antitumor Activity of TZT‐1027, a Novel Doiastatin 10 Derivative (1997)

Dolastatin 10, a pentapeptide isolated from the marine mollusk Dolabella auricularia , has antitumor activity. TZT‐1027, a dolastatin 10 derivative, is a newly synthesized antitumor compound. We evaluated its antitumor activity against a variety of transplantable tumors in mice. Intermittent injections of TZT‐1027 were more effective than single or repeated injections in rake with P388 leukemia and B16 melanoma. Consequently, TZT‐1027 shows schedule dependency. TZT‐1027 was effective against P388 leukemia not only when administered i.p., but also when given i.v. However, although TZT‐1027 given i.v. was active against murine solid tumors, TZT‐1027 administered i.p. was ineffective against all the tumors tested with the exception of colon 26 adenocarcinoma. The i.v. injection of TZT‐1027 at a dose of 2.0 mg/Ag remarkably inhibited the growth of three murine solid tumors; colon 26 adenocarcinoma, B16 melanoma and M5076 sarcoma, with T/C values of less than 6%. The antitumor activities of TZT‐1027 against these tumors were superior or comparable to those of the reference agents; dolastatin 10, cisplatin, vincristine, 5‐fluorouracil (5‐FU) and E7010. In experiments with drug‐resistant P388 leukemia, TZT‐1027 showed good activity against cisplatin‐resistant P388 and moderate activity against vincristine‐ and 5‐fluorouracil‐resistant P388, but no activity against adriamycin‐resistant P388. TZT‐1027 was also effective against human xenografts, that is, tumor regression was observed in mice bearing MX‐1 breast and LX‐1 lμng carcinomas. TZT‐1027 at 10 μM almost completely inhibited the assembly of porcine brain microtubules. Therefore, its mechanism of antitumor action seems to he, at least in part, ascrihable to the inhibition of microtubule assembly. Because of its good preclinical activity, TZT‐1027 has been entered into phase I clinical trials.
Origin and distribution of epipolythiodioxopiperazine (ETP) gene clusters in filamentous ascomycetes (2007)

ETP gene clusters appear to have a single origin and have been inherited relatively intact rather than assembling independently in the different ascomycete lineages. This progenitor cluster has given rise to a small number of distinct phylogenetic classes of clusters that are represented in a discontinuous pattern throughout ascomycetes. The disjunct heredity of these clusters is discussed with consideration to multiple instances of independent cluster loss and lateral transfer of gene clusters between lineages.
Clinical Issues in the Management of Patients with Myelodysplasia (2006)

The management of patients with myelodysplasia (MDS) can be quite complex and varies according to both the clinical manifestations in individual patients as well as complicating medical conditions. Allogeneic stem cell transplantation is the only curative treatment, but because of the older age of the patient population must be applied selectively, particularly in those with lower risk MDS as well as in patients whose clinical course is more frankly "preleukemic." Issues pertinent to the use of 5-azacytidine, decitabine and lenalidomide in patients with both higher and lower International Prognostic Staging System (IPSS) stage disease are discussed.
