Seroepidemiology of rubella, measles, HBV, HCV and B19 virus within women in child bearing ages (Saravan City of Sistan and Bloochastan Province)

Present survey basically focused on women between 15-45 years of age resident in a town of Sistan and Baluchistan province named as Saravan city located in border of Pakistan-Iran in order to find out the seropositivity against the viruses in child bearing ages in the above stated under study community. This descriptive cross-sectional study was carried-out from 2001 up to 2002. Saravan town was divided into 4 geographical areas and each area was further sub-divided into 10 blocks and in each block 10 families were chosen randomly. In the next step by referring to each family from the chosen married women with specified age i.e., 15-45 years, 5 mL blood was collected. Serum was then separated and stored at -20°C before the assay. ELISA kit was employed to detect anti B19, anti rubella, anti measles, anti HBV and anti HCV antibody. Furthermore during samples collection a questionnaire filled for each woman under study. This study showed that 89.6% of women understudy were seropositive against measles, rubella (96.2%), B19 (59.2%), HCV (0.8%) and HBV (19.8%), respectively. According to the results of no serious problem with rubella in this area; But, about measles, the present immunity against measles in this area is insufficient. It seems that incidence of B19 infection in this region is same as other places in Iran. The rate of seropositivity against HBV and HCV indicated of these viruses circulating in the population in this area. © 2007 Academic Journals

Interactional effects of climate change factors on the water status, photosynthetic rate, and metabolic regulation in peach

Environmental stress factors caused by climate change affect plant growth and crop production, and pose a growing threat to sustainable agriculture, especially for tree crops. In this context, we sought to investigate the responses to climate change of two Prunus rootstocks (GF677 and Adesoto) budded with Catherina peach cultivar. Plants were grown in 15 L pots in temperature gradient greenhouses for an 18 days acclimation period after which six treatments were applied: [CO2 levels (400 versus 700 mol mol-1), temperature (ambient versus ambient + 4°C), and water availability (well irrigated versus drought)]. After 23 days, the effects of stress were evaluated as changes in physiological and biochemical traits, including expression of relevant genes. Stem water potential decreased under drought stress in plants grafted on GF677 and Adesoto rootstocks; however, elevated CO2 and temperature affected plant water content differently in both combinations. The photosynthetic rate of plants grafted on GF677 increased under high CO2, but decreased under high temperature and drought conditions. The photosynthetic rates of plants grafted onto Adesoto were only affected by drought treatment. Furthermore, in GF677-Catherina plants, elevated CO2 alleviated the effect of drought, whereas in those grafted onto Adesoto, the same condition produced acclimation in the rate. Stomatal conductance decreased under high CO2and drought stress in both graftedrootstocks, and the combination of these conditions improved water-use efficiency.Changes in the sugar content in scion leaves and roots were significantly differentunder the stress conditions in both combinations. Meanwhile, the expression of mostof the assessed genes was significantly affected by treatment. Regarding genotypes,GF677 rootstock showed more changes at the molecular and transcriptomic level thandid Adesoto rootstock. A coordinated shift was found between the physiological statusand the transcriptomic responses. This study revealed adaptive responses to climatechange at the physiological, metabolic, and transcriptomic levels in twoPrunusrootstocks budded with 'Catherina'. Overall, these results demonstrate the resilient capacity andplasticity of these contrasting genotypes, which can be further used to combat ongoingclimate changes and support sustainable peach production

Investigating the Adoption of Precautionary Behaviors Among Young Rural Adults in South Iran During COVID-19

COVID-19 is an unprecedented challenge for public health worldwide. Reducing the incidence of the disease requires protective measures to prevent virus transmission. Understanding those factors influencing preventive behavior is the first step in preventing the spread of the disease. This study investigates factors affecting youth intention and preventive behaviors in the face of COVID-19 through the health belief model by using a cross-sectional survey collected through an online questionnaire. The sample comprises 304 rural youth in South Iran who were selected through a random sampling technique. The results reveal that perceived severity, perceived benefits, public health beliefs, perceived self-efficacy, and the cue to act positively and significantly affect preventive behaviors. The model explains 59% of variance changes in rural youth preventive behaviors during COVID-19. Cue to action is the strongest and self-efficacy was the weakest determinant of youth's preventive behavior. This study confirms that the HBM framework has appropriate predictive power and is an effective tool for investigating preventive behaviors during COVID-19. These results provide important policy implications for the development of policies that aim to avoid the further spread of COVID-19 between young citizens

Cerebral mGluR5 availability contributes to elevated sleep need and behavioral adjustment after sleep deprivation.

Increased sleep time and intensity quantified as low-frequency brain electrical activity after sleep loss demonstrate that sleep need is homeostatically regulated, yet the underlying molecular mechanisms remain elusive. We here demonstrate that metabotropic glutamate receptors of subtype 5 (mGluR5) contribute to the molecular machinery governing sleep-wake homeostasis. Using positron emission tomography, magnetic resonance spectroscopy, and electroencephalography in humans, we find that increased mGluR5 availability after sleep loss tightly correlates with behavioral and electroencephalographic biomarkers of elevated sleep need. These changes are associated with altered cortical myo-inositol and glycine levels, suggesting sleep loss-induced modifications downstream of mGluR5 signaling. Knock-out mice without functional mGluR5 exhibit severe dysregulation of sleep-wake homeostasis, including lack of recovery sleep and impaired behavioral adjustment to a novel task after sleep deprivation. The data suggest that mGluR5 contribute to the brain's coping mechanisms with sleep deprivation and point to a novel target to improve disturbed wakefulness and sleep

Nursing workload in intensive care units and the influence of patient and nurse characteristics

Background Understanding factors that can potentially influence patient care and nursing workload in intensive care units is important. Previous studies have shown contradictory outcomes about the relationships between nursing workload and patient and nurse characteristics. Aims and objectives This study aimed to investigate nursing workload in intensive care units and examine the association between this in relation to patient and nurse characteristics. Design A cross‐sectional design was conducted. Methods All nurses who were working in the intensive care units of five hospitals and met the study criteria were enrolled in the study. Two demographic questionnaires collected nurse and patient demographic information. The Nursing Activities Score was applied to determine nursing workload in three shifts (morning, evening, night) for each nurse. Data were analysed using the independent sample t‐test, one‐way analysis of variance, and multivariable linear regression analysis. Results The Nursing Activities Score was calculated for 509 patients who were under the care of 105 intensive care unit nurses. The mean (SD) Nursing Activities Score was 72.84% (22.07%). Morning shifts, male patients, medical treatments, and referred patients from the emergency ward and other intensive care units imposed a higher workload for nurses. Specifically, female nurses, increased number of patients receiving care, and increased patient length of intensive care unit stay were directly associated with increased Nursing Activities Scores. Work in surgical and burn intensive care units were inversely associated with the Nursing Activities Score. Conclusion This study suggests that the workload of nurses in intensive care units can be affected by both nurse and patient characteristics. Relevance to clinical practice The findings can be used to ensure appropriate staffing of intensive care units by nurses. However, nurse and patient characteristics should not be considered the only factors that influence nursing workload in intensive care units

Gendered Representations of Male and Female Social Actors in Iranian Educational Materials

This research investigates the representations of gendered social actors within the subversionary discourse of equal educational opportunities for males and females in Iranian English as a Foreign Language (EFL) books. Using critical discourse analysis (CDA) as the theoretical framework, the authors blend van Leeuwen’s (Texts and practices: Readings in critical discourse analysis, Routledge, London, 2003) ‘Social Actor Network Model’ and Sunderland’s (Gendered discourses, Palgrave Macmillan, Hampshire, 2004) ‘Gendered Discourses Model’ in order to examine the depictions of male and female social actors within this gendered discourse. The gendered discourse of equal opportunities was buttressed by such representations within a tight perspective in proportion to gender ideologies prevailing in Iran. Resorting to CDA, we can claim that resistance against such gendered discourse in Iranian EFL textbooks militates against such gender norms. These representations of male and female social actors in school books are indicative of an all-encompassing education, reinforcing that the discourse of equal opportunities is yet to be realized in the education system of Iran

Distribution of ancestral proto-Actinopterygian chromosome arms within the genomes of 4R-derivative salmonid fishes (Rainbow trout and Atlantic salmon)

Comparative genomic studies suggest that the modern day assemblage of ray-finned fishes have descended from an ancestral grouping of fishes that possessed 12-13 linkage groups. All jawed vertebrates are postulated to have experienced two whole genome duplications (WGD) in their ancestry (2R duplication). Salmonids have experienced one additional WGD (4R duplication event) compared to most extant teleosts which underwent a further 3R WGD compared to other vertebrates. We describe the organization of the 4R chromosomal segments of the proto-rayfinned fish karyotype in Atlantic salmon and rainbow trout based upon their comparative syntenies with two model species of 3R ray-finned fishes. Results: Evidence is presented for the retention of large whole-arm affinities between the ancestral linkage groups of the ray-finned fishes, and the 50 homeologous chromosomal segments in Atlantic salmon and rainbow trout. In the comparisons between the two salmonid species, there is also evidence for the retention of large whole-arm homeologous affinities that are associated with the retention of duplicated markers. Five of the 7 pairs of chromosomal arm regions expressing the highest level of duplicate gene expression in rainbow trout share homologous synteny to the 5 pairs of homeologs with the greatest duplicate gene expression in Atlantic salmon. These regions are derived from proto-Actinopterygian linkage groups B, C, E, J and K. Conclusion: Two chromosome arms in Danio rerio and Oryzias latipes (descendants of the 3R duplication) can, in most instances be related to at least 4 whole or partial chromosomal arms in the salmonid species. Multiple arm assignments in the two salmonid species do not clearly support a 13 proto-linkage group model, and suggest that a 12 proto-linkage group arrangement (i.e., a separate single chromosome duplication and ancestral fusion/fissions/recombination within the putative G/H/I groupings) may have occurred in the more basal soft-rayed fishes. We also found evidence supporting the model that ancestral linkage group M underwent a single chromosome duplication following the 3R duplication. In the salmonids, the M ancestral linkage groups are localized to 5 whole arm, and 3 partial arm regions (i.e., 6 whole arm regions expected). Thus, 3 distinct ancestral linkage groups are postulated to have existed in the G/H and M lineage chromosomes in the ancestor of the salmonids

Imagining new feminist futures:How feminist social movements contest the neoliberalization of feminism in an increasingly corporate‐dominated world

Increasingly it is argued that feminism has been co‐opted by neoliberal agendas: becoming more individualistic and losing touch with its wider social change objectives. The neoliberalization of feminism is driven in part by increased corporate power, including the growing role of corporations in governance arenas, and corporate social responsibility agendas. However, we turn to social movement theory to elucidate strategies that social movements, including feminist social movements, are adopting in such spaces. In so doing, we find that feminist activists are engaging with new political opportunities, mobilizing structures and strategic framing processes that emerge in the context of increasingly neoliberal and privatized governance systems. We suggest that despite the significant challenges to their agendas, far from being co‐opted by neoliberalism, feminist social movements remain robust, existing alongside and developing new strategies to contest the neoliberalization of feminism in a variety of innovative ways
