Conservative treatment with total parenteral nutrition in patients with gastroesophageal anastomotic leaks (anastomotic leaks conservatively treated).

Seventeen patients with anastomotic leaks after operation for cardiac or upper gastric cancers were treated conservatively with parenteral nutrition, antibiotics and drainage. Ten patients healed after in mean 33 days, while seven died. All febrile patients had elevation of blood urea, and four had abnormal hepatic enzymes during the parenteral nutrition. There were no significant venous or infectious complications due to the parenteral nutrition.

[Conservative treatment of cruciate ligament rupture. Magnetic resonance tomography provides prognostic information for conservative healing].

Ruptures of the cruciate ligaments continue to pose both diagnostic and therapeutic problems. On the basis of structural analysis of MR images obtained after the accident and the results of conservative treatment, it can be shown that function healing of the rupture can result, when, for example, the synovial membrane (capsule) is preserved (70%). It proved possible to show and objectify this using MRI and measurements.

[Sphincter conservation and cancer of the lower rectum: argument for a multicenter prospective study for conservation of the sphincter after irradiation].

Rectal adenocarcinoma located less than 6 cm from the pectineate line raise the issue of sphincter preservation. Preoperative treatment response can modify the initial indication of surgery. With good response, conservative surgery can be performed with a distal margin less than 2 cm. Conversely a lack of response requires an abdominoperineal resection. Removal technique must emphasize a total mesorectal excision and a prevention of urosexual complications. Intersphincteric resection allows to increase distal margin without continence dysfunction. Regional lymphadenectomy doesn't increase regional control. Digestive tract reconstruction combines coloanal anastomosis and J colonic pouch whenever anatomical conditions are favorable. Long-term follow up should validate this therapeutic approach.

Evolutionary conservation of KLF transcription factors and functional conservation of human gamma-globin gene regulation in chicken.

The Krüppel-like factors (KLFs) are a family of Cys2His2 zinc-finger DNA binding proteins with homology to Drosophila Krüppel. KLFs can bind to CACCC elements, which are important in controlling developmental programs. The CACCC promoter element is critical for the developmental regulation of the human gamma-globin gene. In the present study, chicken homologues of the human KLF2, 3, 4, 5, 9, 11, 12, 13, and 15 genes were identified. Phylogenetic analysis confirms that these genes are more closely related to their human homologues than they are to other chicken KLFs. This work also represents the first systematic study of the expression patterns of KLFs during erythroid development. In addition, transient transfections of human globin constructs into 5-day (primitive) chicken red blood cells show that human gamma-globin expression is regulated via its CACCC promoter element. This indicates that a CACCC-binding factor(s) important for gamma-globin expression functions in 5-day chicken red cells.

KIR3DL3 allelic diversity: six new alleles exhibit both conservative and non-conservative substitutions.

KIR3DL3 alleles were characterized in two families and one unrelated individual. Based on exon 2-9 nucleotide sequences, six novel alleles, 3DL3*00402, *005, *006, *007, *00801, *00802, were identified bringing the total number of known alleles to 11. Compared with 3DL3*001, the six new alleles differ by from three to nine nucleotides and from three to four amino acids. The new alleles double the number of known polymorphic positions to 18 with variation in exons encoding the extracellular domains, transmembrane region, and a portion of the cytoplasmic tail. Many of the nucleotide substitutions are shared among alleles of 3DL3 or other KIR loci, but five were found only in single 3DL3 alleles. Comparison of intron sequences among individuals carrying the same allele showed a modest number of substitutions with the exception of 3DL3*001 which differed substantially in its intron sequences. Two alleles sharing coding region sequences, 3DL3*00201 and 3DL3*00202, were also substantially different in intron sequences.

Conserved and non-conserved loci of the glucagon gene in old world ruminating ungulates.

The homology and diversification of genomic sequence encoding glucagon gene among native Egyptian buffalos, camel and sheep were tested using cattle as model. Oligodeoxynucleotide primers designed from the available GenBank data were used for PCR probing of the glucagon gene encoding sequence at different loci. The DNA oligomer probes were constructed to flank either the whole gene encoding sequence or different intra-gene encoding sequences. The PCR products were visualized using agarose gel electrophoresis. All species showed a same size band of prepro-glucagon when PCR was used to amplify the whole gene encoding sequence. In contrary, amplifications of different intra-gene loci failed to give the same results. The results indicated variable degrees of diversity among old world ruminating ungulates in the glucagon gene encoding sequence. Compared with other ruminants, the variation appears predominantly in camel. Surprisingly, the similarity in size between both amplification products of whole gene encoding sequence and the proposed size of glucagon cDNA definitely excludes the possibility of large intervening introns spanning the genomic sequence of the glucagon gene in these species. This indicates that, in contrast to other tested mammals, the glucagon gene includes an essentially full-length copy of glucagon mRNA. The study revealed a possible new aspect of glucagon gene evolution in order to correlate its corresponding protein function among different ruminant species.

Murine monoclonal antibodies specific for conserved and non-conserved antigenic determinants of the human and murine Ku autoantigens.

The Ku autoantigen is a DNA binding factor consisting of 70 and approximately 80 kDa proteins (p70 and p80, respectively) which form a heterodimer. The p70/p80 dimer appears to be crucial for the function of a 350 kDa DNA-dependent protein kinase (DNA-PK) that phosphorylates certain transcription factors in vitro. Previous studies have suggested that Ku is abundant in primate cells, but undetectable in most non-primate cells. However, it is unclear if this reflects low abundance of Ku (and possibly DNA-PK activity) in non-primate cells, a lack of antibodies crossreactive with non-primate Ku proteins, or both. Ku was first identified with human autoimmune sera, but the suitability of these sera for studying the distribution, abundance and function of Ku is limited by the polyclonal immune response to Ku and the presence of contaminating autoantibodies in most patients' sera. In the present studies, we determined the specificities of murine anti-Ku monoclonal antibodies (mAbs) using cellular Ku as well as recombinant human and murine Ku antigens. Immunofluorescence studies confirmed previous observations that Ku is undetectable in most nonprimate cells. However, small amounts of Ku could be detected in MOPC-315, but not L-929, cells by immunoprecipitating with mAb 162. In addition, autoantibodies to Ku were identified in the sera of approximately 1/3 of MRL/lpr mice. The murine autoantibodies also immunoprecipitated a small amount of Ku (comparable to that seen with 162) from MOPC-315, but not L-929, cell lysates. Characterization of the mAb specificities by immunoblot analysis with Ku fusion proteins revealed that mAbs 111, S10B1, and N9C1 bound to distinct epitopes of human p80 (amino acids 610-705, 8-221, and 1-374, respectively). All three mAbs were unreactive with murine p80. MAbs N3H10 and S5C11 bound immediately adjacent to the DNA binding site of p70 (amino acids 506-541). Only N3H10 displayed comparable reactivity with human and murine p70 on immunoblots, but it immunoprecipitated murine Ku poorly. S5C11 crossreacted more weakly with murine p70 on immunoblots, whereas 162 was completely unreactive with human or murine Ku on immunoblots, despite immunoprecipitating Ku efficiently. Studies with mAbs N3H10 and 162 suggest that the level of Ku is considerably lower in nonprimate cells than cells of primate origin, and that L-929 cells express little or no Ku protein.(ABSTRACT TRUNCATED AT 400 WORDS)
