Curating divinity: Religious souvenirs, shopkeepers and bazaar curation

This paper explores the universe of souvenirs of Sikh Gurus and martyrs available in the bazaars around Sikhism’s most sacred shrine, the Darbar Sahib in Amritsar. Rather like objects in museum exhibitions, souvenir art actively produces ideas of divinity and martyrdom. The deliberate arrangements of Guru and martyr souvenirs in shopwindows demonstrate the ‘sense’ of curation of ordinary shopkeepers in the bazaar. Shop displays, I argue, resemble the care of sacred art by museum curators. But there is more to shop displays than mere imitation. I analyse the vis-à-vis between the souvenir displays of two modern martyrs, Jarnail Singh Bhindranwale, the militant leader of separatist Khalistan, and Bhagat Singh, the nationalist hero, that express bazaar understandings of martyr souvenirs as affective objects, possessing both ritual and political value. The curated displays in museums and shopwindows are critical in creating a conscious, purposive aura around modern Sikh martyrdom

FastMRI Prostate: A Publicly Available, Biparametric MRI Dataset to Advance Machine Learning for Prostate Cancer Imaging

The fastMRI brain and knee dataset has enabled significant advances in exploring reconstruction methods for improving speed and image quality for Magnetic Resonance Imaging (MRI) via novel, clinically relevant reconstruction approaches. In this study, we describe the April 2023 expansion of the fastMRI dataset to include biparametric prostate MRI data acquired on a clinical population. The dataset consists of raw k-space and reconstructed images for T2-weighted and diffusion-weighted sequences along with slice-level labels that indicate the presence and grade of prostate cancer. As has been the case with fastMRI, increasing accessibility to raw prostate MRI data will further facilitate research in MR image reconstruction and evaluation with the larger goal of improving the utility of MRI for prostate cancer detection and evaluation. The dataset is available at https://fastmri.med.nyu.edu.Comment: 4 pages, 1 figur

The Labour of Love: Seasonal Migration from Jharkhand to the Brick Kilns of Other States in India

Seasonal casual labour migration in India has conventionally been understood as the result of extreme poverty whereby villagers are forced to become migrants for the dry six months to subsist or merely survive. This article draws on fieldwork in a village in Jharkhand and a brick kiln in West Bengal to argue that migrants do not understand their movement in economic terms alone. Many see the brick kilns as a temporary space of freedom to escape problems back home, explore a new country, gain independence from parents or live out prohibited amorous relationships. It is suggested that Jharkhandi activists and policy-makers’ construction of such migration as a ‘problem’ is as much about their vision of how the new tribal state ought to be as about exploitation. Migration to the kilns is seen by them as a threat to the purity and regulation of the social and sexual tribal citizen. This moralising perspective creates a climate that paradoxically encourages many young people to flee to the brick kilns where they can live ‘freely’. In this way, the new puritanism at home helps to reproduce the conditions for capitalist exploitation and the extraction of surplus value

Myosin Sequestration Regulates Sarcomere Function, Cardiomyocyte Energetics, and Metabolism, Informing the Pathogenesis of Hypertrophic Cardiomyopathy

BACKGROUND: Hypertrophic cardiomyopathy (HCM) is caused by pathogenic variants in sarcomere protein genes that evoke hypercontractility, poor relaxation, and increased energy consumption by the heart and increased patient risks for arrhythmias and heart failure. Recent studies show that pathogenic missense variants in myosin, the molecular motor of the sarcomere, are clustered in residues that participate in dynamic conformational states of sarcomere proteins. We hypothesized that these conformations are essential to adapt contractile output for energy conservation and that pathophysiology of HCM results from destabilization of these conformations. METHODS: We assayed myosin ATP binding to define the proportion of myosins in the super relaxed state (SRX) conformation or the disordered relaxed state (DRX) conformation in healthy rodent and human hearts, at baseline and in response to reduced hemodynamic demands of hibernation or pathogenic HCM variants. To determine the relationships between myosin conformations, sarcomere function, and cell biology, we assessed contractility, relaxation, and cardiomyocyte morphology and metabolism, with and without an allosteric modulator of myosin ATPase activity. We then tested whether the positions of myosin variants of unknown clinical significance that were identified in patients with HCM, predicted functional consequences and associations with heart failure and arrhythmias. RESULTS: Myosins undergo physiological shifts between the SRX conformation that maximizes energy conservation and the DRX conformation that enables cross-bridge formation with greater ATP consumption. Systemic hemodynamic requirements, pharmacological modulators of myosin, and pathogenic myosin missense mutations influenced the proportions of these conformations. Hibernation increased the proportion of myosins in the SRX conformation, whereas pathogenic variants destabilized these and increased the proportion of myosins in the DRX conformation, which enhanced cardiomyocyte contractility, but impaired relaxation and evoked hypertrophic remodeling with increased energetic stress. Using structural locations to stratify variants of unknown clinical significance, we showed that the variants that destabilized myosin conformations were associated with higher rates of heart failure and arrhythmias in patients with HCM. CONCLUSIONS: Myosin conformations establish work-energy equipoise that is essential for life-long cellular homeostasis and heart function. Destabilization of myosin energy-conserving states promotes contractile abnormalities, morphological and metabolic remodeling, and adverse clinical outcomes in patients with HCM. Therapeutic restabilization corrects cellular contractile and metabolic phenotypes and may limit these adverse clinical outcomes in patients with HCM

Risk factors for myocardial infarction among low socioeconomic status South Indian population

<p>Abstract</p> <p>Background</p> <p>As longevity increases, cases of myocardial infarction (MI) are likely to be more. Cardiovascular disease (CVD) is a major global health problem reaching epidemic proportions in the Indian subcontinent, also among low socio-economic status (SES) and thin individuals.</p> <p>Objectives</p> <p>The present study was undertaken to elicit risk factors for MI among low SES Southern Indians and to find out its association with body mass index (BMI).</p> <p>Materials and methods</p> <p>A case-control study of patients with MI matched against healthy control subjects was carried out in a tertiary care teaching hospital. Standard methods were followed to elicit risk factors and BMI. Chi-square and Fishers exact test for categorical versus categorical, to show relationship with risk factors were analyzed.</p> <p>Results</p> <p>A total of 949 patients (male (M) = 692 and post menopausal female (F) = 257) and 611 age and sex matched healthy controls were included. In our study, BMI was below 23 in 48.2% of patients and below 21 in 22.5%. The risk of developing MI was significantly more in males (odds ratio (OR) = 3.3, 95% confidence interval (C.I.) = 2.69-4.13), among females with post-menopausal duration (PMD) of more than or equal to 3 years (OR = 9.27, 95% C.I. = 6.36-13.50) and in those with BMI less than 23 with one or other risk factors (P = 0.002, OR = 1.38, 95% C.I. = 1.13-1.70).</p> <p>Conclusion</p> <p>BMI cannot be considered as a lone independent risk factor, as the study population had low BMI but had one or more modifiable risk factors. It would be advisable to keep BMI at least 21 kg/m²for screening program. Health education on life style modification and programs to diagnose and control diabetes and hypertension have to be initiated at community level in order to reduce the occurrence.</p

Chickpea

The narrow genetic base of cultivated chickpea warrants systematic collection, documentation and evaluation of chickpea germplasm and particularly wild Cicer species for effective and efficient use in chickpea breeding programmes. Limiting factors to crop production, possible solutions and ways to overcome them, importance of wild relatives and barriers to alien gene introgression and strategies to overcome them and traits for base broadening have been discussed. It has been clearly demonstrated that resistance to major biotic and abiotic stresses can be successfully introgressed from the primary gene pool comprising progenitor species. However, many desirable traits including high degree of resistance to multiple stresses that are present in the species belonging to secondary and tertiary gene pools can also be introgressed by using special techniques to overcome pre- and post-fertilization barriers. Besides resistance to various biotic and abiotic stresses, the yield QTLs have also been introgressed from wild Cicer species to cultivated varieties. Status and importance of molecular markers, genome mapping and genomic tools for chickpea improvement are elaborated. Because of major genes for various biotic and abiotic stresses, the transfer of agronomically important traits into elite cultivars has been made easy and practical through marker-assisted selection and marker-assisted backcross. The usefulness of molecular markers such as SSR and SNP for the construction of high-density genetic maps of chickpea and for the identification of genes/QTLs for stress resistance, quality and yield contributing traits has also been discussed

HOMBRES EN FAMILIAS / HOMBRES Y FAMILIAS: UNA PERSPECTIVA CRÍTICA DESDE LA INDIA

Este escrito busca llamar la atención sobre la forma de identificar el apoyo de los hombres como un ámbito de posibilidades en el que las cuestiones de la democracia doméstica pueden ser miradas dentro de un contexto discursivo. Aceptar el apoyo como un marco de partida nos permite comprometernos con un lenguaje particular de la masculinidad. Las prácticas de apoyo son, por lo tanto, más que un marco alternativo dentro del cual ubicar a los hombres. Facilitan escuchar un aspecto de sus vidas mediante expresiones de sus posiciones subjetivas, en formas que no han sido tenidas en cuenta. Las prácticas de apoyo son un dialecto que explica subjetividades agenciales y proporciona un lenguaje de compromiso con las vidas y los espacios culturales de los hombres

Servitude and sacrifice: masculinity and domestic labour

What does it mean to be a male servant in modern India? The rich anthropological literatures on �home�, �sexuality� and �work� have been oddly remiss in addressing the issue of masculinity and domestic work. More often spoken for than speaking, the life of a servant has an indistinct quality that begs attention. Using biography as a method to frame life lived as a male servant I suggest that a �servant biography� is completed only in a subsequent life with which it is linked, imaginatively and substantively. Further, the historiography of servitude positions the female worker as the principal actor, so that the template upon which an understanding of domestic work is built is feminine. Additionally drawing on the literature on veiling and gender, I set myself the task of retrieving the male servant
