Salmonella enterica serotype Typhi strains (n = 113) were isolated from typhoid patients over a period of 2 decades, i.e. 1987–2006. RAPD and ERIC PCR methods were used for random whole genome typing of these strains. ERIC PCR was found to be very efficient with the discriminatory index (DI) of 0.9821 with 100% reproducibility. RAPD was satisfactory in discriminating the strains (DI = 0.8978) but with poor reproducibility (40%). However, composite genotypic analysis was still better with DI of 0.9981 but with inherent poor reproducibility due to RAPD. Two major clones were observed to be circulating in the community with few unrelated strains too. The dendrogram constructed based on ERIC PCR banding pattern by involving 89 Typhi strains revealed 71 patterns, indicating that the genome of the bacterium is capable of rapid changes and variations. Thus, the spectrum of biological manifestations of human infection by S. Typhi may be related to its capacity for genetic diversity underlined by its highly plastic hypermutable genome. 相似文献

Artemisia nilagirica (Clarke) is a widely used medicinal herb in Indian traditional system of medicine. Therefore, the present study was designed to evaluate the effects of A. nilagirica extracts/fractions on inhibition of proliferation and apoptosis in a human monocytic leukemia (THP-1) cell line. The crude extracts (A. nilagirica ethyl acetate extract [ANE] and A. nilagirica methanolic extract [ANA]) showed cytotoxic activity toward THP-1 cells with the IC50 values of 38.21 ± 7.37 and 132.41 ± 7.19 µg/ml, respectively. However, the cytotoxic activity of active fractions (ANE-B and ANM-9) obtained after column chromatography was found to be much more pronounced than their parent extracts. The IC50 values of ANE-B and ANM-9 were found to be 27.04 ± 2.54 µg/ml and 12.70 ± 4.79 µg/ml, respectively, suggesting greater susceptibility of the malignant cells. Cell cycle analysis and terminal deoxynucleotidyl transferase (TdT)-mediated dUTP nick-end-labeling (TUNEL) assay revealed that inhibition of cell growth by A. nilagirica fractions on THP-1 cells was mediated by apoptosis. Active fractions of A. nilagirica increased the expression levels of caspase-3, ?7, and poly-ADP-ribose polymerase (PARP), a critical member of the apoptotic pathway. These results suggested that active fractions of A. nilagirica may play a promising role in growth suppression by inducing apoptosis in human monocytic leukemic cells via mitochondria-dependent and death receptor-dependent apoptotic pathways. 相似文献

The aim of this study is to prospectively evaluate and model surrogate explanatory variables (SEVs) of target coverage and rectal dose pertaining to soft tissue anatomy visualised on cone beam computed tomography (CBCT) for incorporation into post‐prostatectomy treatment coverage verification protocols. Twenty post‐prostatectomy patients treated with conformal prostate bed radiotherapy (64–74 Gy) underwent CBCT daily at fractions 1 to 5, and then weekly. Treatment coverage was defined on each CBCT using ‘PTV95’, percentage of the CBCT PTV covered by original treatment fields, and ‘RECTD50’, dose delivered to 50% of CBCT rectal volume by original treatment fields. Three candidate SEVs for treatment coverage were defined for each scan: anterior rectal wall movement, change in bladder length and bladder base movement. Both anterior rectal wall movement and increase in bladder length predicted for the decreased PTV95 (P < 0.001 for each). Anterior movement of the anterior rectal wall predicted for increased RECTD50 (P < 0.001). Predictive models for the PTV95 and RECTD50 that accept the significant SEVs as inputs were developed. We developed simple CBCT‐acquired soft tissue anatomic surrogate measures that signal changes in target coverage and rectal dose during post‐prostatectomy radiotherapy. Conventional bony anatomy patient position verification protocols were inadequate in accounting for soft tissue target and organ variation seen with CBCT. 相似文献

Spontaneous, complete resolution of inflammatory pseudotumour (IPT) of lungs is exceptionally rare. A 44-year-old male was referred for evaluation for «non resolving pneumonitis». He had cough and minimal expectoration for 5 months, chest pain, haemoptysis and fever for a fortnight. Computed tomography of thorax (CT-thorax) confirmed the presence of a homogenous mass with irregular borders in right middle lobe with areas of breakdown and air bronchogram. Transbronchial lung biopsy was suggestive of «plasma cell granuloma». Thoracotomy disclosed a hard mass in right middle lobe adherent to lower lobe, chest wall and mediastinum which could not be removed. A wedge biopsy confirmed IPT. Chest radiograph after 4 weeks revealed significant resolution. CT-thorax a year later showed fibrotic scar. Till date, there are only five reports documenting 6 patients with spontaneous resolution of IPT of lungs and in 4 this occurred within 3 months of an invasive diagnostic intervention. 相似文献

The ethanolic extract of seeds of Cuminum cyminum (C.c) was found to improve glucose tolerance to the tune of around 18.3% (P < 0.01) in normal rats and shows around 17.7% (P < 0.01) and 17.1% fall on blood glucose levels at 0–300 and 0–1440 min, respectively, on streptozotocin-induced diabetic rats at an oral dose of 250 mg/Kg body weight. The extract has also been found to improve around 26.7% (P < 0.01) glucose intolerance on 14th day post treatment in high fructose fed streptozotocin-induced diabetic rats. The extract was also found to have antidyslipidemic activity as evident by 21.04% (P < 0.01) decline in serum triglycerides, 22.7% (P < 0.01) decline in total serum cholesterol, and 16.9% of decline in serum LDL-C, respectively, along with 12.2% (P < 0.05) increase in serum HDL-C on high fat diet fed male Syrian golden hamster. The extract was also found inhibitory to eye lens aldose reductase (EC 1.1.1.21) with IC50 value of 7.07 μg/ml as compared to the standard AR inhibiting compound Quercetin which showed IC50 2.35 μg/ml. The extract was also found inhibitory to α-glucosidase with IC50 value of 100 μg/ml as compared to known drug Acarbose which showed IC50 of around 25 μg/ml. 相似文献

Of the 253 neonates admitted to a neonate intensive care unit during the period Jan 91 to Sep 93, 43 neonates died. Autopsy was done in 23 of these (53%). The mean duration of stay of the neonates in the intensive care unit prior to death was 5.6 days (range 2 hours to 10 days). Antemortem diagnoses included asphyxia neonatorum (4), meconium aspiration syndrome (2), septicemia (5), prematurity (3), birth trauma (2), congenital anomalies (2), hypoxic ischemic encephalopathy (1), and non-specific diagnosis (4). There were 6 major autopsy findings that, if known prior to death, would have altered clinical management and might have resulted in cure or prolonged survival. There were 8 additional major findings that, if known prior to death, would not have altered management There were 14 minor findings related to major diagnoses but unrelated to the primary cause of death.KEY WORDS: Autopsy, Cause of death, Perinatal mortality 相似文献
