The COVID‐19 pandemic exposes underlying inequalities in our socio‐economic and health systems, such as gender‐based violence (GBV). In emergencies, particularly ones that involve quarantine, GBV often increases. Policymakers must utilize community expertise, technology and existing global guidelines to disrupt these trends in the early stages of the COVID‐19 epidemic. Gender norms and roles relegating women to the realm of care work puts them on the frontlines in an epidemic, while often excluding them from developing the response. It is critical to value women’s roles in society and include their voices in the decision‐making process to avoid unintended consequences and ensure a comprehensive response that caters to the needs of the most vulnerable groups. 相似文献

Plasma and liver microsomal fatty acid patterns of female rats (Rattus norvegicus) with either low or high serum levels of prolactin (PRL) were studied. Hyperprolactinemia was achieved by grafting anterior pituitary glands or by estradiol administration. One group treated with estradiol also received bromocriptine to inhibit PRL secretion. Ovariectomized (OVX) rats showed a decrease in PRL levels as compared with intact animals (controls). Rats possessing high levels of circulating PRL showed a significant decrease of linoleic acid in the fatty acid pattern of total and polar liver microsomal lipids. High PRL levels in the presence of normal estrogen levels significantly increased arachidonic acid in the same group of lipids. The group of rats treated with estrogen evidenced a decrease in arachidonic acid and in the unsaturation index. From these results it is possible to infer a decrease in the activity of the desaturases. The changes observed in the estradiol-treated group were not modified by bromocriptine administration. OVX rats showed no changes when compared with controls. It is concluded that, while PRL decreases the microsomal unsaturation index, estrogen administration causes a decrease in poly-unsaturated fatty acid biosynthesis and that this effect is independent of PRL levels. 相似文献

Apomorphine-elicited stereotypic behavior and motor activity were studied in rats given one-dose (3g/kg,p.o.) or 14 days (6g/kg/day, p.o.) of ethanol. Apomorphine-elicited stereotypic behavior was enhanced while motor activitu was not significantly affected in both the acute- and chronic ethanol-treated animals. Acute ethanol treatment did not affect but chronic treatment increased the concentration of 3H-spiroperidol binding sites in the striatum. No significant change in binding affinity was observed. 相似文献

Single vs. repeated microwave exposure: effects on benzodiazepine receptors in the brain of the rat.
We studied the effects of single (45 min) and repeated (ten daily 45-min sessions) microwave exposures (2450-MHz, 1 mW/cm2, average whole-body SAR of 0.6 W/kg, pulsed at 500 pps with pulse width of 2 microseconds) on the concentration and affinity of benzodiazepine receptors in the cerebral cortex, hippocampus, and cerebellum of the rat. We used a receptor-binding assay with 3H-flunitrazepam as ligand. Immediately after a single exposure, an increase in the concentration of receptor was observed in the cerebral cortex, but no significant effect was observed in the hippocampus or cerebellum. No significant change in binding affinity of the receptors was observed in any of the brain-regions studied. In rats subjected to repeated exposures, no significant change in receptor concentration was found in the cerebral cortex immediately after the last exposure, which may indicate an adaptation to repeated exposures. Our data also show that handling and exposure procedures in our experiments did not significantly affect benzodiazepine receptors in the brain. Because benzodiazepine receptors in the brain are responsive to anxiety and stress, our data support the hypothesis that low-intensity microwave irradiation can be a source of stress. 相似文献

A. terreus isolates isolated from some bakery products, corn and rice were found to be able to produce territrems. 90% of theA. terreus isolated from bakery products were able to produce territrem A, with a mean of 0.09 ppm, while 80% ofA. terreus isolates produce territrem B with a mean of 0.24 ppm. On the other hand 31.8% of the isolates ofA. terreus from corn were able to produce territrem A with a mean of 0.44 ppm. ConcerningA. terreus isolates from rice, 66.7% were found to produce territrem A, with a mean of 5.28 ppm, and 77.8% of the isolates produced
territrem B with a mean of 1.79 ppm. 相似文献

Genetic variation in an apomictic grass, heteropogon contortus, in the hawaiian islands 总被引:1,自引:0,他引:1
Random amplified polymorphic DNA (RAPD) markers were used to assess genetic variation within and among Hawaiian populations of an apomictic grass, Heterogopon contortus (pili grass). From among 56 individuals sampled from six populations on O'Ahu and Hawai'i, 55 unique genotypes were detected using 33 polymorphic markers. This lack of uniformity among individuals may indicate frequent sexual reproduction in these populations. Analysis of molecular variance (AMOVA) revealed significant variation among populations (30.2%), but higher levels of variation within populations (68.1%). Cluster analysis revealed a high degree of clustering for most populations, but populations from different islands did not cluster together. The presence of among-population differentiation but lack of between-island differentiation may suggest that H. contortus was an early Polynesian introduction to the Hawaiian Islands. 相似文献

Rapid development of tolerance upon central injection of LSD 总被引:1,自引:0,他引:1
LSD given into the lateral ventricle produces a dose-dependent rise in temperature accompanied by behavioral excitation. Tolerance to the pyretogenic effect rapidly develops upon intraventricular (ICV) injection of LSD following an intravenous injection of the same drug. Both Cinanserin and Cyproheptadine attenuate the pyretogenic response induced by LSD. Phenoxybenzamine attenuates the pyretogenic response induced by LSD to a greater degree than Dibozane. 相似文献

ObjectiveTo determine the predictive value of the “Timed Up & Go” (TUG), a validated assessment tool, on a prospective cohort study and to compare these findings to the ASA classification, an instrument commonly used for quantifying patients’ physical status and anesthetic risk.BackgroundIn the onco-geriatric surgical population it is important to identify patients at increased risk of adverse post-operative outcome to minimize the risk of over- and under-treatment and improve outcome in this population.Methods280 patients ≥70 years undergoing elective surgery for solid tumors were prospectively recruited. Primary endpoint was 30-day morbidity. Pre-operatively TUG was administered and ASA-classification was registered. Data were analyzed using multivariable logistic regression analyses to estimate odds ratios (OR) and 95% confidence intervals (95%-CI). Absolute risks and area under the receiver operating characteristic curves (AUC’s) were calculated.Results180 (64.3%) patients (median age: 76) underwent major surgery. 55 (20.1%) patients experienced major complications. 50.0% of patients with high TUG and 25.6% of patients with ASA≥3 experienced major complications (absolute risks). TUG and ASA were independent predictors of the occurrence of major complications (TUG:OR 3.43; 95%-CI = 1.14–10.35. ASA1 vs. 2:OR 5.91; 95%-CI = 0.93–37.77. ASA1 vs. 3&4:OR 12.77; 95%-CI = 1.84–88.74). AUCTUG was 0.64 (95%-CI = 0.55–0.73, p = 0.001) and AUCASA was 0.59 (95%-CI = 0.51–0.67, p = 0.04).ConclusionsTwice as many onco-geriatric patients at risk of post-operative complications, who might benefit from pre-operative interventions, are identified using TUG than when using ASA. 相似文献
