Mujeres, género y política en la joven república colombiana: una mirada desde la correspondencia personal del General Tomás Cipriano de Mosquera, 1859-1862

Este artículo examina la participación femenina en la vida política colombiana en el siglo XIX, a través de un análisis de cartas escritas por mujeres y dirigidas al General Mosquera. Muestra cómo las mujeres formaban parte de las redes sociales y políticas alrededor del caudillo durante su rebelión contra el gobierno de Mariano Ospina. También revela cómo la correspondencia personal les permitía no sólo solicitar la protección de Mosquera, sino también desempeñar un papel en la política, enviando al general noticias, avisos y opiniones acerca de la guerra civil y los asuntos públicos.A b s t r a c t This article sheds light on female participation in nineteenth century Colombian political life through an analysis of women’s letters to General Mosquera. It shows that women were an integral part of the socio-political and cliental networks that surrounded the caudillo and that played a role in his revolt against the Ospina government. It also reveals how personal correspondence allowed them not only to request Mosquera’s assistance, but, to offer the general information, advice, and opinions, ultimately inserting themselves into a larger world of politics

Rural Appalachian Women Will Suffer Disproportionately if Attempts to Further Restrict Emergency Contraception are Successful

The removal of federal abortion protection has incited fear that restrictions on contraception may be next. Many states now imposing abortion restrictions and bans are in the South and Appalachian Regions of the U.S., where rates of unplanned pregnancy and poor health outcomes are already disproportionately high. Numerous studies have documented variable access to levonorgestrel EC (LNG EC) in community pharmacies, with particularly low rates of access at independent pharmacies that are more likely to be located in rural communities than chain pharmacies. Since the overturn of Roe v. Wade, some large chain pharmacies and online retailers are restricting the purchase of LNG EC, limiting its availability. Some legislators and activists are calling for a ban on EC based on a misunderstanding about its mechanism of action, equating it with abortion. At a time when access to the full range of contraceptive options is more critical than ever, already limited access to LNG EC is worsening. Extensive data on LNG EC availability in 509 pharmacies and 400 health clinics across West Virginia, contextualized with socioeconomic demographics, illustrate existing disparities in LNG EC access

A Qualitative Study of Georgian Youth Who Are on the Street or Institutionalized

Street children, or children who live and/or spend time on the streets, are a vulnerable group of considerable concern to the global public health community. This paper describes the results of two linked qualitative studies conducted with children living or spending time on the street and in orphanages in and around urban areas in the Republic of Georgia between 2005 and 2006. The studies examined perceived causes of children going to the street, as well as indicators of healthy functioning and psychosocial problems among these children. Results on causes indicated a range of “push” factors leading children to the street and “pull” factors that keep children living on the street. Findings also showed a range of internalizing and externalizing mental health symptoms among children on the street and within orphanages. Some differences in responses were found between children living on the street and in institutions. It is important to understand the perspectives of these vulnerable populations to guide decisions on appropriate interventions that address their primary problems

Mycoplasma genitalium among Young, Urban Pregnant Women

Objective. As the consequences of Mycoplasma genitalium in pregnant women are unknown, we examined the relationship between prenatal M. genitalium infection and SAB. Methods. The presence of M. genitalium was determined by PCR in urine from 82 women who subsequently experienced a SAB and 134 women who maintained their pregnancies past 22 weeks gestation. The relationships between M. genitalium and subsequent SAB, demographic, current pregnancy, and reproductive health history characteristics were evaluated. Results. Compared to women without M. genitalium, women with M. genitalium were more likely to report nulliparity (41.7% versus 17.4%, P = .04), history of pelvic inflammatory disease (27.3% versus 8.8%, P = .08), prior C. trachomatis infection (63.6% versus 36.9%, P = .11,) and problems getting pregnant (18.2% versus 4.4%, P = .10). M. genitalium was not associated with SAB (AOR 0.9, 95% CI 0.2–3.8). Conclusions. Pregnant women who test positive for M. genitalium do not have an increased risk of SAB but report a history of reproductive morbidities

Consumption of Health-Related Content on Social Media Among Adolescent Girls: Mixed-Methods Pilot Study

Background: Consumption of health- and fitness-related social media content is a predominant behavior among teenage girls, which puts them at risk for consuming unreliable health-related information. Objective: This mixed-methods study (qualitative and quantitative) assessed health behavior attitudes and practices as well as social media use among adolescent girls. Additionally, similar practices and behaviors of adults who regularly interact with this population were studied. Methods: Girls aged 12-18 years were recruited to complete a 28-item survey and participate in a 45- to 60-minute focus group. Adults who regularly interact with adolescent girls, including parents, teachers, and healthcare professionals, were recruited from the local community and given a link to provide online consent and complete a survey. Results: A total of 27 adolescent girls participated in one of nine focus groups. Participants included 18 high school (age: mean 16.1 years; SD 1.3 years) and 9 middle school (age: mean 12.4 years; SD 0.7 years) girls. Eleven adults completed the online survey. Adolescents used social media to communicate and connect with friends, rather than as a source of health information. Although adolescents may see health-related content, most do not follow health-related pages or share such pages themselves, and fewer are actively searching for this information. Adolescents tend to trust information from familiar sources, and the participants reported that they do not follow official news accounts. Adults considered modeling and discussing healthy behaviors important and reportedly expected adolescents to see some level of health-related, especially fitness-related, content on social media. Conclusions: Education interventions are warranted for both adolescents and adults with whom adolescent girls regularly interact, in the areas of sedentary behavior to guide them to access reliable online health-related information and be judicious consumers of online health information

Unraveling the Complexities of DNA-Dependent Protein Kinase Autophosphorylation

DNA-dependent protein kinase (DNA-PK) orchestrates DNA repair by regulating access to breaks through autophosphorylations within two clusters of sites (ABCDE and PQR). Blocking ABCDE phosphorylation (by alanine mutation) imparts a dominant negative effect, rendering cells hypersensitive to agents that cause DNA double-strand breaks. Here, a mutational approach is used to address the mechanistic basis of this dominant negative effect. Blocking ABCDE phosphorylation hypersensitizes cells to most types of DNA damage (base damage, cross-links, breaks, and damage induced by replication stress), suggesting that DNA-PK binds DNA ends that result from many DNA lesions and that blocking ABCDE phosphorylation sequesters these DNA ends from other repair pathways. This dominant negative effect requires DNA-PK's catalytic activity, as well as phosphorylation of multiple (non-ABCDE) DNA-PK catalytic subunit (DNA-PKcs) sites. PSIPRED analysis indicates that the ABCDE sites are located in the only contiguous extended region of this huge protein that is predicted to be disordered, suggesting a regulatory role(s) and perhaps explaining the large impact ABCDE phosphorylation has on the enzyme's function. Moreover, additional sites in this disordered region contribute to the ABCDE cluster. These data, coupled with recent structural data, suggest a model whereby early phosphorylations promote initiation of nonhomologous end joining (NHEJ), whereas ABCDE phosphorylations, potentially located in a “hinge” region between the two domains, lead to regulated conformational changes that initially promote NHEJ and eventually disengage NHEJ

Galaxy Zoo: Motivations of Citizen Scientists

Citizen science, in which volunteers work with professional scientists to conduct research, is expanding due to large online datasets. To plan projects, it is important to understand volunteers' motivations for participating. This paper analyzes results from an online survey of nearly 11,000 volunteers in Galaxy Zoo, an astronomy citizen science project. Results show that volunteers' primary motivation is a desire to contribute to scientific research. We encourage other citizen science projects to study the motivations of their volunteers, to see whether and how these results may be generalized to inform the field of citizen science.Comment: 41 pages, including 6 figures and one appendix.

Galaxy Zoo: Exploring the Motivations of Citizen Science Volunteers

The Galaxy Zoo citizen science website invites anyone with an Internet connection to participate in research by classifying galaxies from the Sloan Digital Sky Survey. As of April 2009, more than 200,000 volunteers had made more than 100 million galaxy classifications. In this paper, we present results of a pilot study into the motivations and demographics of Galaxy Zoo volunteers, and define a technique to determine motivations from free responses that can be used in larger multiple-choice surveys with similar populations. Our categories form the basis for a future survey, with the goal of determining the prevalence of each motivation.Comment: 15 pages, 3 figure

Cerebellar c9RAN proteins associate with clinical and neuropathological characteristics of C9ORF72 repeat expansion carriers.

Clinical and neuropathological characteristics associated with G4C2 repeat expansions in chromosome 9 open reading frame 72 (C9ORF72), the most common genetic cause of amyotrophic lateral sclerosis (ALS) and frontotemporal dementia, are highly variable. To gain insight on the molecular basis for the heterogeneity among C9ORF72 mutation carriers, we evaluated associations between features of disease and levels of two abundantly expressed "c9RAN proteins" produced by repeat-associated non-ATG (RAN) translation of the expanded repeat. For these studies, we took a departure from traditional immunohistochemical approaches and instead employed immunoassays to quantitatively measure poly(GP) and poly(GA) levels in cerebellum, frontal cortex, motor cortex, and/or hippocampus from 55 C9ORF72 mutation carriers [12 patients with ALS, 24 with frontotemporal lobar degeneration (FTLD) and 19 with FTLD with motor neuron disease (FTLD-MND)]. We additionally investigated associations between levels of poly(GP) or poly(GA) and cognitive impairment in 15 C9ORF72 ALS patients for whom neuropsychological data were available. Among the neuroanatomical regions investigated, poly(GP) levels were highest in the cerebellum. In this same region, associations between poly(GP) and both neuropathological and clinical features were detected. Specifically, cerebellar poly(GP) levels were significantly lower in patients with ALS compared to patients with FTLD or FTLD-MND. Furthermore, cerebellar poly(GP) associated with cognitive score in our cohort of 15 patients. In the cerebellum, poly(GA) levels similarly trended lower in the ALS subgroup compared to FTLD or FTLD-MND subgroups, but no association between cerebellar poly(GA) and cognitive score was detected. Both cerebellar poly(GP) and poly(GA) associated with C9ORF72 variant 3 mRNA expression, but not variant 1 expression, repeat size, disease onset, or survival after onset. Overall, these data indicate that cerebellar abnormalities, as evidenced by poly(GP) accumulation, associate with neuropathological and clinical phenotypes, in particular cognitive impairment, of C9ORF72 mutation carriers
