This paper addresses the problem of the differential presentation of illness by women and men in two Spiritualist temples and a physician's office situated in rural Mexico. Women's morbidity raises the broader anthropological questions of the interplay between symptomatic expression and women's unequal status in the social structure, their cognitive evaluation of specific life experiences, cultural etiological explanations and Western models of dysphoria. Symptoms presented by patients in different health care delivery sites are compared and case vignettes of patients' illnesses and attributions are presented to demonstrate the ways in which culturally constructed illness attributions and illness expressions comprise a somatic grammar for the articulation of experiential distress. The sick population is compared with a control group of healthy women to highlight the socio-cultural and psychosocial variables that promote illness in women from the same sociocultural strata of rural Mexico. Collective understandings of the role of life events and emotional expression in illness attributions legitimize somatization as a coping style under adverse existential conditions. 相似文献

The biocontrol properties of Trichoderma species are well documented, but their effectiveness in antagonism of the problematic Sclerotium cepivorum, the causal agent of white rot in Allium species, appears limited with reports of significant control only relating to deliberately-mutated strains of Trichoderma. Our previous studies have indicated the possibility of using selected naturally-occurring strains of the antagonist in the suppression of other diseases; now in vitro and controlled environment in vivo studies have indicated that a degree of control of Onion White Rot is possible, and that the selected antagonist strains can be used in integrated treatments with Iprodione to good effect. The possible value of such treatments is considered in light of other approaches to the suppression of this continuing problem. 相似文献

Background/AimsThe aim of this study was to compare the cytotoxic response against ovarian cancer (OC) cells elicited by different immune effector cells in combination with the cytokines interleukin (IL)-2 and interferon (IFN) α-2b.MethodsOC cells were co-cultured with peripheral blood mononuclear cells (PBMC) from normal donors or OC patients and IL-2 or IFN α-2b alone or in combination, in order to determine the cytotoxicity. T cells were isolated from healthy donors to determine T cell cytotoxic activity. PBMC from healthy donors and OC patients were expanded in an IL-2/IL-7/IL-12 cocktail with and without anti-CD3 antibody, and the cytotoxic activity measured. Flow cytometry was performed on primary, selected and expanded cells to determine T, B, and natural killer- (NK) cell percentages.ResultsHealthy donor PBMC elicited a significant cytotoxic response (59%) compared with OC patient PBMC (7%). T cells enriched from normal donors elicited a significant cytotoxic response (18%) compared with controls lacking effector cells (1.4%); however, the cytotoxicity observed was significantly less compared with unselected PBMC. Expanded effector cells consisted primarily of T cells (98%) and the fold-expansion was significantly higher in the presence of anti-CD3 (19- versus 132-fold). No significant difference in the expansion (either fold-expansion or cell type) was observed between OC patients and healthy donors. Expanded cells from both healthy donors and OC patients elicited a significant cytotoxic response in the presence of IL-2 (19% and 22%) compared with controls.ConclusionsPBMC from OC patients do not elicit a significant cytotoxic response; however, ex vivo-expanded cells from OC patients are capable of cytotoxic killing similar to unexpanded T cells isolated from normal donors. These data provide the groundwork for further development of cellular therapy against OC. 相似文献

Separation and cells concentration constitute important stages in most biotechnological processes. Particularly, use of flocculation/sedimentation
can improve significantly the extraction of biopolymers accumulated by microorganisms and the biodegradation of xenobiotic
compounds by cell sludge. In this work the use of tannin and aluminum sulphate (Al2(SO4)3) as flocculating agents for concentration of cells of Cupriavidus necator DSM 545 is evaluated. Cells were grown in broth nutrient medium in Erlenmeyer flasks, submitted to orbital agitation of 160 rpm
at 30 °C for 21 h. The optimal concentrations of flocculating agents, as determined with a standard jar test method, were
equal to 2,800 mg/L for tannin and 800 mg/L for Al2(SO4)3, allowing for recovery of 95% of the cells in both cases. Obtained flocs presented density and average diameter of 1.03 g/mL ± 0.01 g/mL
and 158 μm ± 19 μm for tannin and of 1.05 g/mL ± 0.01 g/mL and 146 μm ± 14 μm for Al2(SO4)3, respectively. Batch settling tests were performed in order to determine the operational capacity of continuous settlers
to be used for separation of the investigated flocculent suspensions. Finally, cultivation of cells using flocs as inoculum
indicated that the cells remained viable after flocculation with usage of the optimum flocculating agent concentrations. 相似文献
