Parasite community structure in sympatric Bornean primates.

Int J Parasitol 2021 Apr 13. Epub 2021 Apr 13.

Primate Research Institute, Kyoto University, Inuyama, Japan; Institute for Tropical Biology and Conservation, Universiti Malaysia Sabah, Kota Kinabalu, Sabah, Malaysia.

Parasites are important components of ecosystems, influencing trophic networks, competitive interactions and biodiversity patterns. Nonetheless, we are not nearly close to disentangling their complex roles in natural systems. Southeast Asia falls within global areas targeted as most likely to source parasites with zoonotic potential, where high rates of land conversion and fragmentation have altered the circulation of wildlife species and their parasites, potentially resulting in altered host-parasite systems.

Risk of emergency surgery for complicated appendicitis: Japanese nationwide study.

Ann Gastroenterol Surg 2021 Mar 9;5(2):236-242. Epub 2020 Nov 9.

The Japanese Society of Gastroenterological Surgery Tokyo Japan.

Aim: Appendicitis is divided into two categories: complicated appendicitis (CA) and uncomplicated appendicitis (UA). In pediatric patients with CA, the use of interval appendectomy (IA), which is non-operative management followed by elective surgery, has decreased the number of postoperative complications. Before discussing the merit of IA for adult patients, we need to clarify whether the frequency and seriousness of the complication rate after emergency surgery is higher for CA than for UA.

Neural correlates of confusability in recognition of morphologically complex Korean words.

PLoS One 2021 15;16(4):e0249111. Epub 2021 Apr 15.

Department of Psychology, Korea University, Seoul, Republic of Korea.

When people confuse and reject a non-word that is created by switching two adjacent letters from an actual word, is called the transposition confusability effect (TCE). The TCE is known to occur at the very early stages of visual word recognition with such unit exchange as letters or syllables, but little is known about the brain mechanisms of TCE. In this study, we examined the neural correlates of TCE and the effect of a morpheme boundary placement on TCE. Read More

Ancient and modern mitogenomes from Central Argentina: new insights into population continuity, temporal depth and migration in South America.

Hum Mol Genet 2021 Apr 15. Epub 2021 Apr 15.

Universidad Nacional de Córdoba, Facultad de Filosofía y Humanidades, Departamento de Antropología, Córdoba, Argentina.

The inverted triangle shape of South America places Argentina territory as a geographical crossroads between the two principal peopling streams that followed either the Pacific or the Atlantic coasts, which could have then merged in Central Argentina. Although the genetic diversity from this region is therefore crucial to decipher past population movements in South America, its characterization has been overlooked so far. We report 92 modern and 22 ancient mitogenomes spanning a temporal range of 5000 years, which were compared to a large set of previously reported data. Read More

Genetic evidence for the association between COVID-19 epidemic severity and timing of non-pharmaceutical interventions.

Nat Commun 2021 04 12;12(1):2188. Epub 2021 Apr 12.

MRC Centre for Global Infectious Disease Analysis and the Department of Infectious Disease Epidemiology, Imperial College London, London, UK.

Unprecedented public health interventions including travel restrictions and national lockdowns have been implemented to stem the COVID-19 epidemic, but the effectiveness of non-pharmaceutical interventions is still debated. We carried out a phylogenetic analysis of more than 29,000 publicly available whole genome SARS-CoV-2 sequences from 57 locations to estimate the time that the epidemic originated in different places. These estimates were examined in relation to the dates of the most stringent interventions in each location as well as to the number of cumulative COVID-19 deaths and phylodynamic estimates of epidemic size.

Genetics animates structure: leveraging genetic interactions to study the dynamics of ribosome biogenesis.

Curr Genet 2021 Apr 12. Epub 2021 Apr 12.

Department of Molecular Biosciences, The University of Texas at Austin, Austin, TX, USA.

The assembly of eukaryotic ribosomes follows an assembly line-like pathway in which numerous trans-acting biogenesis factors act on discrete pre-ribosomal intermediates to progressively shape the nascent subunits into their final functional architecture. Recent advances in cryo-electron microscopy have led to high-resolution structures of many pre-ribosomal intermediates; however, these static snapshots do not capture the dynamic transitions between these intermediates. To this end, molecular genetics can be leveraged to reveal how the biogenesis factors drive these dynamic transitions. Read More
