Global distribution of incidence, mortality, and burden of stomach cancers and its relationship with the sociodemographic index

Objective: Stomach cancer ranked sixth among the most common cancers in 2020, with approximately 1.1 million new cases and approximately 76,900 deaths. Therefore, estimations of the incidence and mortality, and burden of stomach cancers are needed to plan for cancer control. In this study, the updated distribution of incidence, mortality, and global burden of stomach cancer based on different classifications was investigated according to the Global Burden of Disease (GBD) 2019 Study. Materials and Methods: Epidemiological data have been derived from the study of the GBD in 2019. Data were extracted globally for 204 countries and groups based on a sociodemographic index (SDI), world health organization (WHO) regions, continents, World Bank regions, and 21 GBD regions. The correlations with SDI were investigated by Spearman's rho correlation coefficient and SPSS 2016 software. Results: The global distribution of incidence, mortality, and burden of stomach cancers varies in different geographical areas. Mortality and burden of stomach cancer are related to sociodemographic indicators of countries. No correlation was detected between the incidence of stomach cancer and SDI. Gender is also one of the effective factors in the death and incidence of stomach cancer. Conclusions: Estimating the cancer burden, taking into account both mortality and morbidity, is a key step in prioritizing research and policy. It can also be used to prioritize when combined with data on the cost of cancer interventions

Rice-Magnaporthe transcriptomics reveals host defense activation induced by red seaweed-biostimulant in rice plants

Red seaweed extracts have been shown to trigger the biotic stress tolerance in several crops. However, reports on transcriptional modifications in plants treated with seaweed biostimulant are limited. To understand the specific response of rice to blast disease in seaweed-biostimulant-primed and non-primed plants, transcriptomics of a susceptible rice cultivar IR-64 was carried out at zero and 48 h post inoculation with Magnaporthe oryzae (strain MG-01). A total of 3498 differentially expressed genes (DEGs) were identified; 1116 DEGs were explicitly regulated in pathogen-inoculated treatments. Functional analysis showed that most DEGs were involved in metabolism, transport, signaling, and defense. In a glass house, artificial inoculation of MG-01 on seaweed-primed plants resulted in the restricted spread of the pathogen leading to the confined blast disease lesions, primarily attributed to reactive oxygen species (ROS) accumulation. The DEGs in the primed plants were defense-related transcription factors, kinases, pathogenesis-related genes, peroxidases, and growth-related genes. The beta-D-xylosidase, a putative gene that helps in secondary cell wall reinforcement, was downregulated in non-primed plants, whereas it upregulated in the primed plants indicating its role in the host defense. Additionally, Phenylalanine ammonia-lyase, pathogenesis-related Bet-v-I family protein, chalcone synthase, chitinases, WRKY, AP2/ERF, and MYB families were upregulated in seaweed and challenge inoculated rice plants. Thus, our study shows that priming rice plants with seaweed bio-stimulants resulted in the induction of the defense in rice against blast disease. This phenomenon is contributed to early protection through ROS, protein kinase, accumulation of secondary metabolites, and cell wall strengthening

Living Law, Legal Pluralism, and Corruption in Post-Soviet Uzbekistan

This paper aims to explore the multifaceted meaning, logic, and morality of informal transactions in order to better understand the social context that informs the meaning of corruption and bribery in post-Soviet Uzbekistan. It will be argued that the informal transactions in Uzbek society reflect different cultural and functional meanings from those in most of the Western world, and hence transactions that from a Western-centric perspective would be labelled as bribes can be morally accepted transactions in the Uzbek cultural context. If this is true, there may be reasons to re-evaluate the relevance of the Western-centric interpretations of corruption in the context of Uzbekistan, and possibly other Central Asian countries. These issues will be investigated with reference to observations and informal interviews from post-Soviet Uzbekistan. This study is based on three periods of ethnographic field research between 2009 and 2012 in the Ferghana Province of Uzbekistan. It draws on concepts of ‘living law’ and legal pluralism to provide a theoretical framework

Long term records of erosional change from marine ferromanganese crusts

Ferromanganese crusts from the Atlantic, Indian and Pacific Oceans record the Nd and Pb isotope compositions of the water masses from which they form as hydrogenous precipitates. The10Be/9Be-calibrated time series for crusts are compared to estimates based on Co-contents, from which the equatorial Pacific crusts studied are inferred to have recorded ca. 60 Ma of Pacific deep water history. Time series of ɛNd show that the oceans have maintained a strong provinciality in Nd isotopic composition, determined by terrigenous inputs, over periods of up to 60 Ma. Superimposed on the distinct basin-specific signatures are variations in Nd and Pb isotope time series which have been particularly marked over the last 5 Ma. It is shown that changes in erosional inputs, particularly associated with Himalayan uplift and the northern hemisphere glaciation have influenced Indian and Atlantic Ocean deep water isotopic compositions respectively. There is no evidence so far for an imprint of the final closure of the Panama Isthmus on the Pb and Nd isotopic composition in either Atlantic or Pacific deep water masses

Global, regional, and national prevalence and mortality burden of sickle cell disease, 2000-2021: a systematic analysis from the Global Burden of Disease Study 2021

BACKGROUND: Previous global analyses, with known underdiagnosis and single cause per death attribution systems, provide only a small insight into the suspected high population health effect of sickle cell disease. Completed as part of the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2021, this study delivers a comprehensive global assessment of prevalence of sickle cell disease and mortality burden by age and sex for 204 countries and territories from 2000 to 2021. METHODS: We estimated cause-specific sickle cell disease mortality using standardised GBD approaches, in which each death is assigned to a single underlying cause, to estimate mortality rates from the International Classification of Diseases (ICD)-coded vital registration, surveillance, and verbal autopsy data. In parallel, our goal was to estimate a more accurate account of sickle cell disease health burden using four types of epidemiological data on sickle cell disease: birth incidence, age-specific prevalence, with-condition mortality (total deaths), and excess mortality (excess deaths). Systematic reviews, supplemented with ICD-coded hospital discharge and insurance claims data, informed this modelling approach. We employed DisMod-MR 2.1 to triangulate between these measures-borrowing strength from predictive covariates and across age, time, and geography-and generated internally consistent estimates of incidence, prevalence, and mortality for three distinct genotypes of sickle cell disease: homozygous sickle cell disease and severe sickle cell β-thalassaemia, sickle-haemoglobin C disease, and mild sickle cell β-thalassaemia. Summing the three models yielded final estimates of incidence at birth, prevalence by age and sex, and total sickle cell disease mortality, the latter of which was compared directly against cause-specific mortality estimates to evaluate differences in mortality burden assessment and implications for the Sustainable Development Goals (SDGs). FINDINGS: Between 2000 and 2021, national incidence rates of sickle cell disease were relatively stable, but total births of babies with sickle cell disease increased globally by 13·7% (95% uncertainty interval 11·1-16·5), to 515 000 (425 000-614 000), primarily due to population growth in the Caribbean and western and central sub-Saharan Africa. The number of people living with sickle cell disease globally increased by 41·4% (38·3-44·9), from 5·46 million (4·62-6·45) in 2000 to 7·74 million (6·51-9·2) in 2021. We estimated 34 400 (25 000-45 200) cause-specific all-age deaths globally in 2021, but total sickle cell disease mortality burden was nearly 11-times higher at 376 000 (303 000-467 000). In children younger than 5 years, there were 81 100 (58 800-108 000) deaths, ranking total sickle cell disease mortality as 12th (compared to 40th for cause-specific sickle cell disease mortality) across all causes estimated by the GBD in 2021. INTERPRETATION: Our findings show a strikingly high contribution of sickle cell disease to all-cause mortality that is not apparent when each death is assigned to only a single cause. Sickle cell disease mortality burden is highest in children, especially in countries with the greatest under-5 mortality rates. Without comprehensive strategies to address morbidity and mortality associated with sickle cell disease, attainment of SDG 3.1, 3.2, and 3.4 is uncertain. Widespread data gaps and correspondingly high uncertainty in the estimates highlight the urgent need for routine and sustained surveillance efforts, further research to assess the contribution of conditions associated with sickle cell disease, and widespread deployment of evidence-based prevention and treatment for those with sickle cell disease.

Diagenetic remobilization of rare earth elements in a sediment core from the central Indian basin

341-344Rare earth elements (REE) distribution in a 36 cm long sediment box core from the Central Indian Basin is studied. REE concentration is generally higher in the upper oxic zone than in intermediate suboxic zone suggesting REE diffusion upwards the sediment column and subsequent incorporation in the oxyhydroxide phase. The similarity in depth distribution of bulk REE concentration, solid Mn phase and micronodule abundance from the coarse fraction suggest that micronodules are one of the major component controlling the REE distribution in a sediment column
