Lucy Faulkner and the 'ghastly grin': Reworking the title page illustration to Goblin Market
An article that recovers the work of the craftswoman Lucy Faulkner Orrinsmith. It demonstrates her role in the re-cutting of the title page illustration to Christina Rossetti’s poem ‘Goblin Market’ designed by D. G. Rossetti in 1862-5
An Overview of the Field of Semiotics
AbstractThe quantitative increase in recent years of research into semiotics, among other methods of reading works of art, is notable. Since semiotics is the act of reading as based on a meta-language that is constructed and grounded in logic, understanding the methods applied by the field requires time and experience. In addition, the application of models that differ in relation to each other under different schools of thought and under different names makes its yet more difficult to comprehend the field of semiotics. Despite the different models that are available, approaches display certain commonalities as they are born of the same foundations and objectives. This study will aim to pinpoint the common aspects of the intellectual foundations, methods, objectives and research limitations of the different schools of thought and the models that are involved in the study of semiotics
The Role of Translation Initiation Regulation in Haematopoiesis
Organisation of RNAs into functional subgroups that are translated in response to extrinsic and intrinsic factors underlines a relatively unexplored gene expression modulation that drives cell fate in the same manner as regulation of the transcriptome by transcription factors. Recent studies on the molecular mechanisms of inflammatory responses and haematological disorders indicate clearly that the regulation of mRNA translation at the level of translation initiation, mRNA stability, and protein isoform synthesis is implicated in the tight regulation of gene expression. This paper outlines how these posttranscriptional control mechanisms, including control at the level of translation initiation factors and the role of RNA binding proteins, affect hematopoiesis. The clinical relevance of these mechanisms in haematological disorders indicates clearly the potential therapeutic implications and the need of molecular tools that allow measurement at the level of translational control. Although the importance of miRNAs in translation control is well recognised and studied extensively, this paper will exclude detailed account of this level of control
Associations of gestational glycemia and prepregnancy adiposity with offspring growth and adiposity in an Asian population
Background: maternal obesity and hyperglycemia increase risk of obesity and diabetes in offspring later in life.Objective: we examined the relation between gestational glycemia and prepregnancy body mass index (ppBMI) with offspring growth in an Asian mother-offspring cohort.Design: pregnant mothers undertook a 75-g 2-h oral-glucose-tolerance test at 26–28 wk of gestation. In 937 singleton offspring, ?9 serial measurements of weight and length were obtained from birth until 36 mo of age.Results: gestational fasting plasma glucose (FPG) was positively associated with birth weight (B: 0.17; 95% CI: 0.10, 0.24; P < 0.001) and birth BMI (B: 0.15; 95% CI: 0.06, 0.40; P = 0.001) but not at ?3 mo of age. In contrast, maternal ppBMI was positively associated with birth variables and conditional growth in weight and BMI in the first 36 mo of life. However, gestational FPG and prepregnancy obesity status interacted significantly for the association with offspring growth and overweight status in the first 36 mo of life (P-interaction < 0.01). In nonobese mothers, each unit increase in gestational FPG was associated with increased offspring weight (B: 0.08; 95% CI: 0.008, 0.16; P = 0.03) and BMI (B: 0.08; 95% CI: 0.003, 0.15; P = 0.04) as well as increased risk of overweight in the first 36 mo of life (OR: 1.36; 95% CI: 1.10, 1.68). However, in obese mothers, each unit increase in gestational FPG was associated with decreased offspring weight (B: ?0.01; 95% CI: ?0.02, ?0.003) and BMI (B: ?0.008; 95% CI: ?0.01, ?0.002) velocity (P < 0.01 for both) and decreased risk of overweight (OR: 0.59; 95% CI: 0.41, 0.86) in the first 36 mo of life.Conclusions: prepregnancy adiposity was associated with offspring growth in early childhood. Although pooled analyses showed no demonstrable difference by 3 mo of age, there were contrasting and opposite associations of gestational glycemia with weight and BMI in the first 36 mo of life in offspring of nonobese and obese mothers separately. This study was registered at clinicaltrials.gov as NCT0117487
Ethnic differences translate to inadequacy of high-risk screening for gestational diabetes mellitus in an Asian population: a cohort study
Background: universal and high-risk screening for gestational diabetes mellitus (GDM) has been widely studied and debated. Few studies have assessed GDM screening in Asian populations and even fewer have compared Asian ethnic groups in a single multi-ethnic population.Methods: 1136 pregnant women (56.7% Chinese, 25.5% Malay and 17.8% Indian) from the Growing Up in Singapore Towards healthy Outcomes (GUSTO) birth cohort study were screened for GDM by 75-g oral glucose tolerance test (OGTT) at 26–28 weeks of gestation. GDM was defined using the World Health Organization (WHO) criteria. High-risk screening is based on the guidelines of the UK National Institute for Health and Clinical Excellence.Results: universal screening detected significantly more cases than high-risk screening [crude OR 2.2 (95% CI 1.7-2.8)], particularly for Chinese women [crude OR = 3.5 (95% CI 2.5-5.0)]. Pre-pregnancy BMI > 30 kg/m2 (adjusted OR = 3.4, 95% CI 1.5-7.9) and previous GDM history (adjusted OR = 6.6, 95% CI 1.2-37.3) were associated with increased risk of GDM in Malay women while GDM history was the only significant risk factor for GDM in Chinese women (adjusted OR = 4.7, 95% CI 2.0-11.0).Conclusion: risk factors used in high-risk screening do not sufficiently predict GDM risk and failed to detect half the GDM cases in Asian women. Asian women, particularly Chinese, should be screened to avoid under-diagnosis of GDM and thereby optimize maternal and fetal outcome
Changing times: the evolution of puberty
An evolutionary and life history perspective is used to consider the evolution of puberty. The age of menarche would have evolved by the Neolithic to be matched to social maturity. It is suggested that in developed countries menarche is now returning to a similar age as in the Neolithic as infection and undernutrition, features of post-Neolithic society, have reduced impact. But recently the psychosocial expectations on adolescents in western societies have changed and social maturity now significantly follows menarche. The implications of the developing mismatch between the ages of biological puberty and social maturation are discussed. Evolutionary arguments are presented to explain the unique pubertal growth spurt of humans. Moreover, a life history perspective can reconcile the apparently conflicting observations that both poor fetal growth and better childhood nutrition are associated with earlier menarche
