Review of proposed different irradiation methods to inactivate food-processing viruses and microorganisms.

Food Sci Nutr 2021 Oct 22;9(10):5883-5896. Epub 2021 Aug 22.

Food Technology Division School of Industrial Technology Universiti Sains Malaysia Penang Malaysia.

Coronaviruses, which have been enveloped nonsegmented positive-sense RNA viruses, were first mentioned in the mid-1960s and can attack people as well as a wide range of animals (including mammals and birds). Three zoonotic coronaviruses have been identified as the cause of large-scale epidemics over the last two decades: Middle East respiratory syndrome (MERS), severe acute respiratory syndrome (SARS), and swine acute diarrhea syndrome (SADS). Epithelial cells in the respiratory and gastrointestinal tract are the principal targeted cells, and viral shedding occurs via these systems in diverse ways such as through fomites, air, or feces.

Key Laboratory for Plant Diversity and Biogeography of East Asia Kunming Institute of Botany Chinese Academy of Sciences Kunming China.

Successful pollination in animal-pollinated plants depends on the temporal overlap between flower presentation and pollinator foraging activity. Variation in the temporal dimension of plant-pollinator networks has been investigated intensely across flowering seasons. However, over the course of a day, the dynamics of plant-pollinator interactions may vary strongly due environmental fluctuations. Read More

Chromosome X-wide Analysis of Positive Selection in Human Populations: Common and Private Signals of Selection and its Impact on Inactivated Genes and Enhancers.

Front Genet 2021 27;12:714491. Epub 2021 Sep 27.

Institut de Biologia Evolutiva (UPF-CSIC), Universitat Pompeu Fabra, Barcelona, Spain.

The ability of detecting adaptive (positive) selection in the genome has opened the possibility of understanding the genetic basis of population-specific adaptations genome-wide. Here, we present the analysis of recent selective sweeps, specifically in the X chromosome, in human populations from the third phase of the 1,000 Genomes Project using three different haplotype-based statistics. We describe instances of recent positive selection that fit the criteria of hard or soft sweeps, and detect a higher number of events among sub-Saharan Africans than non-Africans (Europe and East Asia).

School of Physics and Information Engineering, Shanxi Normal University, No.1 Gongyuan Road, Yaodu District, Linfen 041004, China.

Designing oxygen reduction reaction (ORR) catalysts with excellent performance has far-reaching significance. In this work, a high-activity biomass free-metal carbon catalyst with N and S co-doped was successfully prepared by using the KOH activated awn stem powder as the precursor with organic matter pore-forming doping technology, which is named TAAS. The content of pyridine nitrogen groups accounts for up to 36% of the total nitrogen content, and a rich pore structure is formed on the surface and inside, which are considered as the potential active centers of ORR.

Detection Methods and Status of CAT Interruption of in Korean Patients With Spinocerebellar Ataxia Type 1.

Ann Lab Med 2022 Mar;42(2):274-277

Department of Laboratory Medicine and Genetics, Sungkyunkwan University School of Medicine, Seoul, Korea.

Spinocerebellar ataxia type 1 (SCA1) is an autosomal dominant disease caused by abnormal CAG repeat expansion in the ataxin 1 gene (). The presence of CAT interruption(s) is important for diagnosing SCA1 in patients with 39-44 repeat alleles, as only uninterrupted alleles are considered abnormal. Determining the CAT interruption status might also be important for patients with >44 repeats, as the length of the longest uninterrupted CAG repeat stretch has been correlated with age at SCA1 onset.

Unparalleled disjunction or unexpected relationships? Molecular phylogeny and biogeography of Melanopsidae (Caenogastropoda: Cerithioidea), with the description of a new family and a new genus from the ancient continent Zealandia.

Cladistics 2019 Aug 9;35(4):401-425. Epub 2018 Dec 9.

Department of Animal Diversity, Center of Natural History (CeNak), Zoological Museum, Universität Hamburg, Martin-Luther-King-Platz 3, D-20146, Hamburg, Germany.

Melanopsidae are an important component of the freshwater fauna of the subtropical to temperate regions of the Western Palaearctic and also are reported from Zealandia, representing an unparalleled disjunction among a group of freshwater animals. We sequenced markers for species of all constituent genera covering the entire range of the group. Our phylogenetic analyses indicate that Melanopsidae are only monophyletic when excluding Holandriana from the Balkans, which was found to be more closely related to Pleuroceridae (eastern North America) and Semisuclospiridae (western North America and eastern Asia) than to the remaining melanopsids.
