Summary The French version of the Marcé checklist was used to collect data for 176 joint admissions to 11 psychiatric mother-baby units in 1999 and 2000. Mean age of the babies at admission ranged from 4 to 16 weeks. Two units also admitted older children. Mothers admitted were diagnosed with schizophrenia or chronic delusional disorders (n=44), acute transitory psychosis Bouffée délirante (n=20), bipolar disorders (n=20), depressive illness (n=38), personality disorders or intellectual disability (n=39), and other disorders (n=15). The mean duration of hospitalisation was 11 weeks. Units that also offered day-care admission in the same or a near-by unit had shorter mean admissions. More than half the womens partners (or babies fathers) had mental health problems. Women with schizophrenia or chronic delusional disorders and personality disorders or intellectual disability remained hospitalised longer, improved less, and were more often separated from their babies, or discharged with supervision, than women admitted with other diagnoses. 相似文献

The relationship between HPV16 and expression of CD44v6, nm23H1 in esophageal squamous cell carcinoma 总被引:1,自引:0,他引:1
Summary. The esophageal squamous cell carcinoma (ESCC) has high incidence in Shaanxi Province of China. More and more researches indicated that human papillomavirus type 16 (HPV16) might play an important role in carcinogenesis of ESCC but the relationship between HPV16 and CD44v6, nm23H1 has not been elucidated. HPV16 was detected by amplifying HPV16 E6 gene through polymerase chain reaction (PCR) method and the expression of CD44v6, nm23H1 in 40 ESCCs and fifteen normal esophageal mucosa (NEM) from Shaanxi Province was examined by Streptavidin-Peroxidase (SP) method using monoclonal antibody specific to CD44v6 and nm23H1. The positive rates of HPV16 E6 gene, CD44v6 and nm23H1 were 60% (24/40), 65% (26/40) and 45% (18/40) respectively in ESCCs and 26.67% (4/15), 33.33% (5/15) and 86.67% (13/15) respectively in NEMs. There exited statistical difference for HPV16, CD44v6 and nm23H1 between NEMs and ESCCs respectively (p<0.05). The relationship between HPV16 and the expression of CD44v6 in ESCCs was statistical significance (P=0.021), but no significant correlation was found between HPV16 and the expression of nm23H1 (P=0.436) in ESCCs. The infection rate of HPV16 had no statistical difference in all pathological features we observed, but the expression rates of CD44v6 and nm23H1 had statistical correlation with invasion (p=0.001, 0.013) and lymph nodes metastasis (p=0.014, 0.002) respectively. In different histology grade of ESSCs, the relationship between HPV16 and CD44v6 was statistical significance in grade I (p=0.044) but was not in grade II (p=0.165) and grade III (p=0.658), however as to the expression of nm23H1 there exited no statistical significance in all histology grades of ESCC (p>0.05). The expression rates of CD44v6 and nm23H1 were statistically different between grade I and II (p=0.004, 0.016) respectively and between grade I and grade III (p=0.014, 0.020), but not statistically different between grade II and III (p=0.792, 0.943) respectively. Our data firstly suggested that there existed the statistical relationship between the infection of HPV16 and the expression of CD44v6 in ESCCs and that HPV16 may be involved in invasion and metastasis of ESCC. 相似文献

Actin filaments around endothelial fenestrae in rat hepatic sinusoidal endothelial cells 总被引:2,自引:0,他引:2

The presence of microfilaments in the vicinity of sinusoidal endothelial fenestrae (SEF) suggests that the cytoskeleton of liver sinusoidal endothelial cells (LSEC) plays an important role in the modulation of SEF. In this study, we investigated actin filaments around SEF in LSECs. Monolayers of LSEC culture were established by infusing a rat liver with collagenase for 30min and then culturing in RMPI medium for 24h. Cells were reacted with 0.1% Triton X for 5s and 15% glycerinated PHEM buffer (60mM PIPES, 25mM HEPES, 10mM EGTA, 2mM MgCl, pH 6.9) containing heavy meromyosin for 10min and observed under a transmission electron microscope. By electron microscopy with the modified heavy meromyosin decorated reaction, actin filaments were clearly demonstrated around SEF in LSEC. 相似文献

The complete nucleotide sequence of the genome RNA of Lily symptomless virus and its comparison with that of other carlaviruses 总被引:4,自引:0,他引:4
Summary. The complete genomic nucleotide sequence and genome structure of Lily symptomless virus (LSV), a lily-infecting carlavirus, have been obtained. The genome of the Korean strain of LSV, LSV-Kr, was 8,394 nucleotides long and contained six open reading frames (ORFs) coding for proteins of Mr 220kDa (1,948aa), 25kDa (228aa), 12kDa (106aa), 7kDa (64aa), 32kDa (291aa) and 16kDa (140aa) from the 5 to 3 end, respectively, which is typical of carlaviruses. Genetic heterogeneity was observed in the ORF1 gene. A total of 221 of 5,847 nucleotides (nt) were heterologous in the ORF1 of replicase; 162nt portions were silent and 59nt resulted in amino acid changes. This heterogeneity indicates that the LSV-infecting lily plants contained a genetically heterogeneous population of LSV (quasispecies). Overall similarities to those of other carlaviruses for the six ORFs of LSV were from 76.1% to 31.6% and from 87.3% to 13.7%, at nucleotide and amino acid levels, respectively. The ORF1 replicase gene of LSV shares 40.9% to 56.8% and 48.9% and 58.6% identities with that of 5 other carlaviruses at the amino acid and nucleotide levels, respectively. LSV was closest to Blueberry scorch virus (BlScV) in this ORF, among the carlaviruses for which sequence information is available. The three triple gene blocks (ORF2-4), ORF5 (coat protein) and 3-proximal 16kDa ORF6 genes were further analyzed, and phylogenetic trees for the coding regions indicate that the LSV was the most closely related to Kalanchoe latent virus and BlScV. This is the first report of the complete nucleotide sequence and genome structure of LSV.Received December 13, 2002; accepted May 14, 2003

Summary. The nucleotide sequence analysis of the 429bp fragment of the P gene of 11 Polish field isolates of Canine distemper virus (CDV), reference strains and other virus isolates available in the GenBank was the aim of the studies. High homology between all dog strains from east-southern region of Poland and reference strains of CDV was demonstrated. It was estimated as 97–100% for CDV-OND; 96.7–99.8% for CDV-Rock; 96.7–99.8% for CDV-LED and 96.3–97.9% for A75-17. The 100% homology of the nucleotide sequence was observed between CDV Pulawy 92, CDV Pulawy 97 and the reference CDV-OND. The homology between CDV-OND and viruses isolated from the mink and ferret was estimated as 97.7% and 98.4%, respectively. Virus strains isolated from blue foxes demonstrated the highest homology to CDV-OND – equal to 97.7% for DV 79 and 99.5% for DV 92. The fox isolate from 1992 had higher level of homology to dog isolates (96.5–99.5%) than the strain isolated from the fox in 1979 (97.2–98.8%). The phylogenetic tree has two main lineages representing two separated genetic groups: I containing PDV and II containing all distemper virus strains isolated from terrestrial carnivores. CDV strains isolated from dogs from Pulawy region between 1992–1998 and from the fox (DV 92) formed the separate lineage containing also reference strains. They differed from the native isolates from the mink and ferret as well as from Japanese strains of CDV.Received October 29, 2002; accepted April 2, 2003

Several reports indicate that the cytosol is acidified during apoptosis although the mechanism is not yet fully elucidated. The most acidic organelle found in the cell is the lysosome, raising the possibility that lysosomal proton release may contribute to the cytosolic acidification. We here describe methods for measurement of the cytosolic and lysosomal pH in U937 cells by a dual-emission ratiometric technique suitable for flow cytometry. Cytosolic pH was analysed in cells loaded with the fluorescent probe BCECF, while lysosomal pH was determined after endocytosis of FITC-dextran. Standard curves were obtained by incubating cells in buffers with different pH in the presence of the proton ionophore nigericin. Apoptosis was induced by exposure of cells to 10ng/ml TNF- for 4h, and apoptotic cells were identified using a fluorescent marker for active caspases. By gating of control and apoptotic cells, the cytosolic and lysosomal pH were calculated in each population. The cytosolic pH was found to decrease from 7.2 ± 0.1 to 5.8s±0.1 and the lysosomal increased from 4.3±0.4 to 5.2±0.3. These methods will be useful in future attempts to evaluate the involvement of lysosomes in the acidification of the cytosol during apoptosis. 相似文献

Summary.
Seoul virus is a hantavirus that causes hemorrhagic fever with renal syndrome (HFRS). The virion has a tripartite (S, M, and L) negative-stranded RNA genome, which is characteristic of the family Bunyaviridae. However, the molecular basis of virus replication is not well known. We established a Northern blot hybridization (NB) procedure using digoxygenin-labeled RNA probes, to quantitate the hantaviral plus- and minus-strand RNAs separately. Virus RNA replication was analyzed in infected Vero E6 cells. When the Vero E6 cells were infected with Seoul virus strain KI-83-262 (KI) at m.o.i.=0.25, the plus-strand RNA was detected within 1h post-infection (hpi), and the minus-strand RNA was detected subsequently. Using laser confocal microscopy, the nucleocapsid protein (NP) was detected within 2hpi, and accumulated as scattered granules in the cytoplasm until 24hpi. In contrast, the G2 protein first appeared at 8hpi, was immediately transported to the Golgi, and accumulated in the Golgi until 24hpi. Infectious virus particles were released into the medium at 24hhpi. These findings indicate that hantavirus RNA replication starts with the appearance of NP at 2hpi, glycoproteins then accumulate gradually in the Golgi, and virion formation is initiated once the viral RNAs and proteins have accumulated.Received October 10, 2002; accepted April 25, 2003

Detection of enteric viruses and bacterial indicators in German environmental waters 总被引:10,自引:0,他引:10

Summary. A German mining lake and the supplying surface waters, which are located downstream of a sewage plant, were examined regarding their microbiological and virological quality. Between October 2002 and September 2003, specific PCR methods were used to determine the occurrence of enteric viruses in 123 water specimens drawn at different sites downstream of the waste water treatment plant and in 9 samples from the sewage plant influent. Detection rates in sewage plant effluents and surface water samples depended on sampling sites and were: 29–76% for enterovirus (EntV), 24–42% (astrovirus, AstV), 15–53% (norovirus, NV), 3–24% (rotavirus, RoV), 5–20% (hepatitis A virus, HAV) and 20% (adenovirus, AdV). AstV genome load of selected samples was between 3.7×103 to 1.2×108 genome equivalents per liter (gen.equ./l), depending on sampling location; NV average genome load ranged from 1.8×104 to 9.7×105gen.equ./l. Cell culture methods showed that three out of 18 PCR positive samples contained infectious EntV. Even though microbiolical parameters such as Escherichia coli, enterococci and coliphages indicated acceptable microbiological water quality, the virological data of this study suggest the possibility that surface waters may be a source for enteric viral infections. 相似文献

The 5S ribosomal (r) RNA genes encode a small (120-bp) highly-conserved component of the large ribosomal subunit. The objective of the present research was to study the molecular and cytogenetic organization of the chicken 5S rDNA. A predominant 2.2-kb gene (5S) consisting of a coding and intergenic spacer (IGS) region was identified in ten research and commercial populations. A variant gene repeat of 0.6kb (5S) was observed in some of the populations. Genetic linkage analysis and cytogenetic localization by fluorescence in-situ hybridization assigned the 5S rDNA to chromosome 9. The 5S rDNA array was determined to be 80.2±7.0kb upon electrophoretic sizing following EcoRV digestion. Sequence analysis of 5S IGS regions revealed considerable conservation between chicken subspecies (98.4% identity) as well as homology with vertebrate Pol III promoter and regulatory sequence motifs. Minor intraindividual sequence variation within 1000bp of IGS was observed in four cloned Red Jungle Fowl (Gallus gallus gallus) 5S repeats (95.5% identity in this region). Sequence comparisons between IGS regions of 5S and 5S genes indicated two short continuous (>20bp) and many short non-continuous homologous regions as well as other conserved features such as promoter and termination motifs. 相似文献

Summary. The complete nucleotide sequence of Bean yellow mosaic virus (BYMV) gladiolus isolate GDD was determined and compared to broad bean isolates BYMV-MB4 and BYMV-S. The BYMV-GDD genome (9528nt) was more similar to BYMV-MB4 (9532nt) than to BYMV-S (9547nt), which has atypical symptom expression and host range. The greatest variability occurred in the 5 untranslated region, P1 protein, and NIa-VPg protein, the N-terminal two thirds of HC-Pro, and the C-terminal one third of P3. Each of these regions has been correlated with symptom or host differences between isolates of other potyviruses, and may contribute to the atypical nature of BYMV-S. 相似文献

Molecular analysis of <Emphasis Type="Italic">Fiji disease virus</Emphasis> genome segments 5, 6, 8 and 10 总被引:3,自引:0,他引:3
Summary. The complete sequences of Fiji disease virus (FDV) genome segments 5 (S5), S6, S8 and S10 were obtained and comprised 3150nt, 2831nt, 1959nt and 1819nt, respectively. Each segment contained a single ORF which encoded putative proteins of 115kDa, 97kDa, 69kDa and 63.0kDa, respectively. The putative amino acid sequences encoded by S5 and S6 contained putative leucine zipper motifs while FDV S5 and S8 each contained an ATP-GTP-binding motif. At the amino acid level, FDV S5, S6, S8 and S10 showed most similarity to the corresponding segments of Rice black-streaked dwarf virus. Based on sequence similarities, it is predicted that FDV S8 encodes a minor core protein, while FDV S10 encodes an outer capsid protein. The evolutionary relationships of FDV to other reoviruses are discussed.The nucleotide sequence data for FDV S5, S6, S8 and S10 are available in the DDBJ/EMBL/GenBank databases under the accession numbers AY029521, AF356083, AY297693 and AY297694, respectively. 相似文献

Summary. Analysis by enzyme-linked immunosorbent assay showed that Rice tungro bacilliform virus (RTBV) accumulated in a cyclic pattern from early to late stages of infection in tungro-susceptible variety, Taichung Native 1 (TN1), and resistant variety, Balimau Putih, singly infected with RTBV or co-infected with RTBV+Rice tungro spherical virus (RTSV). These changes in virus accumulation resulted in differences in RTBV levels and incidence of infection. The virus levels were expressed relative to those of the susceptible variety and the incidence of infection was assessed at different weeks after inoculation. At a particular time point, RTBV levels in TN1 or Balimau Putih singly infected with RTBV were not significantly different from the virus level in plants co-infected with RTBV+RTSV. The relative RTBV levels in Balimau Putih either singly infected with RTBV or co-infected with RTBV+RTSV were significantly lower than those in TN1. The incidence of RTBV infection varied at different times in Balimau Putih but not in TN1, and to determine the actual infection, the number of plants that became infected at least once anytime during the 4wk observation period was considered. Considering the changes in RTBV accumulation, new parameters for analyzing RTBV resistance were established. Based on these parameters, Balimau Putih was characterized having resistance to virus accumulation although the actual incidence of infection was >75%.Received December 18, 2002; accepted March 19, 2003

Usefulness of low-priming-volume cardiopulmonary bypass circuits and dilutional ultrafiltration in neonatal open-heart surgery 总被引:3,自引:0,他引:3
In neonate open-heart surgery, cardiopulmonary bypass (CPB) with extreme hemodilution induces an increased capillary permeability and accumulation of extravascular fluid, resulting in organ dysfunction. We evaluated the effects of a reduced priming volume for CPB and dilutional ultrafiltration (DUF) during neonatal open-heart surgery. Nineteen consecutive neonates with complete transposition of the great arteries who underwent an arterial switch operation were retrospectively assigned into two groups: the high-priming-volume circuit group (group A, n = 9) and the low-priming-volume circuit group (group B, n = 10). Patients in group B underwent surgery with a miniaturized CPB circuit and using the DUF technique. The priming volume of group B was nearly two-thirds that of group A. The water balance value after CPB and surgery was significantly lower in group B (–126 ± 118ml, –116 ± 116ml) than in group A (88 ± 218ml, 83 ± 165ml). Systolic blood pressure just after CPB was higher in group B (67.9 ± 9.1mmHg) than in group A (55.4 ± 10.3mmHg). Postoperative ventilatory support was shorter in group B (45 ± 19h) than in group A (68 ± 27h). In neonatal cardiac surgery, low-priming-volume CPB circuits and DUF improve the water balance during surgery and may attenuate any inflammatory reaction, which would help preserve postoperative organ function. 相似文献

Identification and Characterization of the UL24 Gene Product of Herpes Simplex Virus Type 2 总被引:5,自引:0,他引:5

The UL24 gene of herpes simplex virus type 2 (HSV-2) is predicted to encode a 281 amino acid protein with a molecular mass of 30.5kDa. In this study, the HSV-2 UL24 gene product has been identified by using a rabbit polyclonal antiserum produced against a recombinant protein containing the full-length UL24 gene product of HSV-2 fused to glutathione-S-transferase. The antiserum reacted specifically with a 32kDa protein in HSV-2 186-infected Vero cells and with 31 and 32kDa proteins in UL24-expressing Cos-7 cells. Accumulation of UL24 protein to detectable levels required viral DNA synthesis, indicating that the protein was regulated as a late gene. UL24 protein was found to be associated with purified HSV-2 virions and C capsids. Indirect immunofluorescence analysis demonstrated that the UL24-specific fluorescence was detected in perinuclear regions of the cytoplasm and/or in the nucleus as small discrete granules from 9h post infection (hpi). Furthermore, the UL24 protein expressed singly was detected predominantly in the nucleus and slightly in the cytoplasm at 24h after transfection, with branch-like cytoplasmic protruding structures. Strong nucleolus staining was visible in partial cells. 相似文献

Summary. The genome of Rice stripe virus (RSV, genus Tenuivirus) contains seven open reading frames (ORFs). Little is known about the products of four of these ORFs, including the 23.9K protein encoded by the virus-sense ORF of RNA3. Western blotting revealed that the 23.9K protein was synthesized in the host plant and also in the planthopper vector of RSV. Using a baculovirus vector, the 23.9K protein was expressed, both unfused and fused with red-shifted green fluorescent protein, in Spodoptera frugiperda cells. Inclusion bodies were observed by light microscope in cells expressing fused or unfused proteins. Inclusion bodies in cells expressing the fused protein fluoresced under blue light. By immunoelectron microscopy, electron-dense inclusion bodies in cells expressing the unfused protein were specifically labeled with 23.9K protein antiserum. Moreover, electron-dense masses labeled with 23.9K protein antiserum were observed in virus-infected wheat tissue by electron microscopy. This paper thus demonstrates that RSV 23.9K protein can aggregate in vivo and form inclusion bodies in infected plant tissue.Received December 24, 2003; accepted June 11, 2003

Nano-scaled sintered hydroxyapatite (HAp) particles with an a-axis length of 87 ± 23nm, a c-axis length of 236 ± 81nm, and a mean aspect ratio (c/a) of 2.72 were covalently linked onto a silk fibroin (SF) substrate chemically modified by graft polymerization with -methacryloxypropyl trimethoxysilane (MPTS). Graft polymerization with poly(MPTS) on SF was conducted by free-radical initiation in a water solvent with pentaethylene glycol dodecyl ether as a nonionic surfactant. The alkoxysilyl groups of the graft polymers avoided hydrolysis and maintained their activity in coupling with the hydroxyl groups on the HAp surface despite the use of water as the reaction solvent. The weight gain of poly(MPTS) on SF increased with increasing the reaction time, eventually reaching a plateau value of about 15wt% after 50min of reaction time. After HAp covalent coating, the particles separated or aggregated into several crystals, as shown by scanning electron microscopic observation. L929 fibroblast cells adhered more plentifully on HAp-coated SF compared to untreated SF and hydrolyzed poly(MPTS)-grafted SF during 24h or 48h of incubation. The cells adhered only on the HAp surface but not at all on the dehydrated grafted surface of SF without HAp. A button-shaped prototype for a percutaneous device was manufactured by transplantation of HAp-coated SF fibers of about 100µm in length onto silicone moldings using an adhesive, and the device showed good cell adhesiveness. 相似文献

Improving the resolution of artificial sensory organs requires an interface that receives external information from electronic circuits and stimulates appropriate neurons individually in response to that information. The method of electric stimulation in available artificial sensory organs is fairly nonselective; therefore, we developed a method of chemical stimulation of neurons using a neurotransmitter containing an electrochemical micropump powered by the bubbling that occurs during water electrolysis. The micropump contains a glass nozzle with a tip 10µm in diameter. Two blackened platinum electrodes for the electrolysis were inserted into the body of the pump, which was filled with neurotransmitter solution. The distance between a neuron of the gastropod Aplysia and the tip of the nozzle was adjusted to about 100µm. A potential difference of 3.0V was applied to the electrodes to propel the solution toward the neuron while its membrane potential was monitored. Administration of 1-mM acetylcholine to a resting neuron caused neural firing only when the voltage was applied for 0.5s and without a time lag. During administration of 50-mM -aminobutyric acid to spontaneously firing neurons, the firing disappeared with a time lag of 1s after application of 3.0V. We concluded that an electrochemical micropump can be applied for rapid neurotransmitter administration to control the excitation and inhibition of neurons. This simple pump can be miniaturized to create synapses in artificial sensory organs. 相似文献

Fiji disease fijivirus (FDV) genomic segments 1 (S1) and 3 (S3) were completely sequenced. FDV S1 comprised 4532nt and was predicted to encode a 170.6kDa protein. FDV S3 comprised 3623nt and was predicted to encode a 135.5kDa protein. The terminal sequences of S1 and S3 were 5 AAGUUUUU......CAGCUAGCGUC 3 and 5 AAGUUUUU......CAGCAGAUGUC 3, respectively, and located immediately adjacent to these sequences were 12bp imperfect inverted repeats. The predicted translation product of FDV S1 showed highest similarity to Rice black-streaked dwarf virus (RBSDV) S1 and is thought to encode the viral RNA-dependent RNA polymerase (RdRp). The predicted translation product of FDV S3 was found to be most similar to RBSDV S4 which is thought to encode the 'B-spike' protein. The FDV sequence contained an ATP/GTP binding motif and a leucine zipper motif, but these motifs were not found in the RBSDV sequence. Phylogenetic analysis based on the amino acid sequences of the RdRp of FDV S1 and other reoviruses revealed that the fijiviruses form a cluster close to the oryzaviruses. The RdRp sequences were grouped into genera that were consistent with the current reovirus classification scheme that is based on physico-chemical and biological properties. 相似文献

Accumulated low molecular weight proteins in hemodialysis patients require a high-flux dialyzer. There have been several methods proposed for enhancing internal filtration, including narrowing the inside diameter of the hollow fibers, lengthening the fibers, and increasing the fiber density ratio. We tried to enhance the internal filtration by increasing the pressure drop in the dialysate compartment through increasing the fiber density ratio. If the fiber density ratio is too high, however, an irregular dialysate path may result, thus decreasing dialysis performance. Therefore, we took note of the shape of the inner housing and added a short taper structure, which improved the dialysate path dramatically. Consequently, we developed an internal filtration-enhanced dialyzer (APS-Prototype) to improve dialysis performance. The internal filtration rate in water (measured by Doppler ultrasound) was 13.2l/session for the APS-Prototype and 5.3l/session for the APS-15E. The amount of 1-microglobulin (1-MG) in bovine plasma was 0.34g for the APS-Prototype and 0.11g for the APS-15E. In addition, the amount of 1-MG in vivo was 29.0% ± 5.8% for the APS-Prototype, significantly higher than that for the APS-15E (13.6% ± 1.9%). The desirable loss of albumin is 2–4g in hemodiafiltration, and it was 3.92 ± 1.03g for the APS-Prototype. The prototype showed excellent solute removal performance with no clinical or engineering problems. 相似文献

Summary. Objective: Pregnancy has frequently been referred to as a time of emotional well-being for patients. However, systematic data about the risk for relapse of depression during pregnancy are sparse.Method: We completed a longitudinal cohort study of thirty-two (N=32) women with histories of depression who were euthymic at conception and who either discontinued or attempted to discontinue antidepressant therapy proximate to conception. Subjects were prospectively followed across pregnancy once per trimester using structured clinical interviews. Rates of relapse and time to relapse were examined. Factors distinguishing the population with respect to risk for relapse including demographic characteristics and illness history were also examined.Results: Seventy-five percent (N=24) of patients relapsed during pregnancy. The majority of relapses (79%, N=19) occurred in the first trimester, and relapse was more prevalent in women with histories of more chronic depression.Conclusions: Pregnancy is not protective with respect to risk for relapse of depression. Careful treatment planning is necessary for those women on antidepressants who plan to conceive or who become pregnant. 相似文献
