A high-pyruvate xanthan gum, substantially free of insolubles and undesirable coloration, is produced by fermentation of Xanthomonas campestris on a carbohydrate-containing nutrient medium having NH4 ; 2HPO4 at a level of at least 0.15% as the primary nitrogen source, and having a total phosphate level of at least about 0.25%. In the production of xanthan gum by action of the Xanthomonas bacteria on a nutrient medium, a low viscosity xanthan gum is produced by adding sulfate anions in a concentration ranging from about 0.2 to about 0.5 wt % of the nutrient medium during the culture of the Xanthomonas bacteria in the nutrient medium. A reduced viscosity xanthan gum is produced which can be converted to the normal viscosity xanthan gum. A process is described for the continuous manufacture of xanthan gum in which continuous culture is conducted under conditions of nutrient limited growth using relatively inexpensive chemically defined media containing certain vitamins with or without amino acids. The process is directed broadly to use of bacteria of the genus Xanthomonas to produce xanthan gum from the aforesaid media and pilocarpine.
Abstract: The cytotoxic effect of photodynamic therapy PDT ; on ovarian clear-cell carcinoma cell line, OvBH-1 was achieved using different methods. No clear morphological changes in OvBH-1 after PDT were observed, whereas PDT-treated MCF-7 breast carcinoma cells demonstrated morphological features of apoptosis. After PDT, OvBH-1 pattern of p53 expression remained unchanged, but MCF-7 cells revealed nuclear cytoplasmic p53 expression. After PDT, a weak Bax protein induction was found in both PDT-treated cell lines. Bcl-2 expression in PDT treated OvBH-1 cells remained unchanged, while it was markedly decreased in PDT treated MCF-7 cell line. MCF-7 cells expressed high level of neoepitope cytokeratin 18 CK 18 ; M30 ; , whereas low expression of neoepitope cytokeratin 18 was found in OvBH-1, after PDT. The photofrin II PDT resulted in a significant reduction of the activity of mitochondrial enzymes in MCF-7 cells , as compared with that of OvBH-1 cells. The photofrin II effect, measured as a percentage of cells with high mitochondrial activity observed in MCF-7 cells at 3 and 6 h after PDT was low 6 and 3%, respectively ; , whereas in these conditions as many as 28.9% at 3 h ; and 30.42% at 6 h ; of OvBH-1 cells showed significantly higher activity of mitochondrial enzymes p 0.001 ; . It is worth underlining that both methods, alkaline comet assay and flow cytometry, revealed that the majority of OvBH-1 cells 7595.4% ; were dead with the signs of necrosis, while in MCF-7 cells most of them 8092% ; died by apoptosis. Our in vitro preliminary results indicate that PDT causes non-apoptotic death in OvBH-1 cell line. Key words: OvBH-1, MCF-7 cell lines, PDT, apoptosis, necrosis.
NF- B and AP-1 are considered to be responsible for tubulointerstitial inflammation 30, 31 ; and possible targets for statins 10 ; . In addition, activation of NF- B by podocytes may contribute to proteinuria in experimental nephritis 32 ; . Accordingly, we performed EMSA to address the NF- B and AP-1 activation in the kidneys and the glomeruli of PAN nephrosis and pima.

Adjacent teeth Table 1 ; . Compared with the controls, there was no significant increase in the total number of branched axons detected p 0.23, Mann-Whitney U test ; , but there was a significant increase in the proportion of branched axons supplying non-adjacent teeth p 0.01, x2 test ; . Adjustment of the stimulus intensity revealed that 21 of the responses between pairs of teeth were from a single unit, but two pairs of teeth had responses from two units. None of the responses in this group, or any of the other groups, was affected when the inferior alveolar nerve was sectioned central to the site of nerve injury, thus confirming that all of the branch points were within the mandibular canal. However, this nerve section abolished the jaw-opening reflex which sometimes interfered with recordings. Responses from all 13 of the axons supplying non-adjacent teeth and three of the axons supplying adjacent teeth.

It is easy to argue that ADT can improve the chances of living longer after being diagnosed with more advanced prostate cancer. However, since men are living longer on ADT for prostate cancer it seems that the side effects from this treatment are gaining more attention. This should not be surprising because men are using this therapy earlier and earlier and with a variety of treatments; therefore, side effects that can be prevented or treated should receive attention. In the old days not that long ago ; , docs only gave ADT to men with very advanced prostate cancer, so side effects from this treatment were not really discussed because the more immediate issue was one of life and death. However, now some men are on or on and off this therapy for years and years so we are beginning to learn more and more about the side effects of ADT. For example, we all know that ADT can cause hot flashes in most men and now we are learning that the longer you are on ADT the greater the chance of bone loss and osteoporosis. Other side effects that have gained some attention are things like reduced sexual function, fatigue, some muscle wasting, weight gain around the belly area, cholesterol changes, decreases in body hair and an increase in scalp hair, and the list goes on. So, researchers in Spain decided to look at thyroid hormone levels because thyroid hormones can impact so many areas of the body. Researchers looked at 182 patients on ADT LHRH alone ; and 119 men on ADT with an anti-androgen pill. The average age of the patients was 70 years old and the average time on ADT was a little more than 3 years. It turns out that and posture.

Figure 4. Immunohistochemical detection of p63 in wt and ER ventral prostate. Positive nuclei counted per 100 revealed statistically significant difference plotted ; . In the table, the number means positive per 100. The next question concerned the cellular composition of the prostatic epithelium in the absence of ER signaling. We approached this question by using fluorescent activated cell sorting of isolated prostatic epithelial cells from wt and ER mice. It turned out that cells positive for Ck19, a basalintermediate cell marker, accumulate in the prostate when ER is knocked out. This means that ER prostate has more cells expressing AR that are sensitive and dependent on androgen stimulation and capable of rapid proliferation upon androgen stimulation. ER therefore seems to be responsible for terminal differentiation of prostatic epithelium. In this study we provided evidence that ER is a prodifferentiative factor for prostatic epithelium and photofrin.

| Photofrin laserTo execute PGD procedures. Biopsy of one or two blastomeres from an 8-cell embryo does not interfere with in-vitro development of embryos Hardy, 1990 ; and therefore the outcome of IVF PGD cycles should not be compromised by further embryo culture to day 5 p.i. A biopsy later on day 3 p.i. allows the operator to conduct the biopsy at an optimum time with regard to embryo development. Despite that, only 63.3% of embryos reached 8-cells or more at the time of biopsy in this study. In practice, PGD offers little choice in quality of embryos for biopsy, and in some cases embryos were also biopsied at the 4- and 5-cell stage, despite reports that this retards embryo development Tarin, 1992 ; . Embryo biopsy of a single blastomere was not detrimental to developmental potential; the blastocyst rate per biopsied embryo was 40 109 36.6% ; and only 14 109 13% ; were classified as poor and unsuitable for transfer based on morphology. Blastocyst development from the embryos biopsied at 8-cells or more was 34 69 49% ; . One main concern of delaying embryo transfer is the possibility of there being no blastocyst available for transfer. In a prospective randomized study only 5% of patients did not have an embryo transfer and implantation rates of 50% were achieved Gardner et al., 1998 ; . As expected, our total figures show lower implantation rates 12 37; 32% ; , but our cohort included biopsied embryos from transfers with a mix of embryo development stages. However, in the seven patients who only had blastocysts transferred, an implantation rate of 8 17 47% ; was achieved. The three patients 20% ; whose embryos did not achieve the blastocyst stage opted for embryo transfer despite poor prospects of pregnancy. Owing to the limited number of embryos available for transfer following PGD after embryo biopsy of only morphologically `good' embryos and suitable genotype after genetic analysis ; it has been recommended that cycles with less than nine oocytecumulus complexes should be cancelled Liebaers et al., 1998 ; . In PGD cases where high numbers of oocytes are retrieved it may be advantageous to culture biopsied embryos to the blastocyst stage despite fears of having no embryos available for transfer. It is interesting to note that the patients with no blastocysts for transfer had amongst the lowest number of oocytes collected Table II ; . The limitations of PGD are great but in Greece, where almost 1 in 10 the population are carriers of -thalassaemia or Hbs, we prefer to offer PGD for couples at risk for transmitting -thalassaemia major as an additional therapy for patients requiring IVF. -thalassaemia is a monogenic recessive genetic disorder and therefore only 25% of embryos are likely to be affected. The proportion of embryos for transfer homozygous normal or heterozygous carrier ; are greater than that of a dominant genetic disorder which would otherwise have greatly diminished the embryos available. The genotyping method based on DGGE used in this study not only facilitates detection of the wide spectrum of mutations underlying -thalassaemia major and sickle cell thalassaemia but also addresses many of the inherent potential problems associated with PCR-based genotyping of single cells, which include total PCR failure, allelic drop-out ADO ; and contamination. DGGE is advantageous since it facilitates simultaneous analysis of more than one mutation in a single PCR fragment, detects the presence of normal as well as pathological alleles 30 and pramlintide.
