ABSTRACT: A retrospective study about the SARS-CoV-2 variants in Sicily (Italy) during the second and third waves of contagions (September 2020 - March 2021)
Project description:After the initial COVID-19 wave, India experienced a second COVID-19 wave in March 2021, which was driven by the delta variant. By January 2021, India has also begun its vaccine campaign. Therefore, semen samples from recovered patients who were infected during the two waves of COVID-19 in India were obtained to study the impact of variants on the male reproductive system. We compared samples from the second wave with those of first wave in India. We also included control samples to the comparison.
Project description:Phenotipic traits related to the reproductive performance of the breeder flock reared at the Centro Avicolo per la Conservazione di Risorse Genetiche Locali (Centro Zootecnico Didattico Sperimentale - CZDS, Università degli Studi di Milano, Lodi) have been recorded from April 2021 to May 2022. In April 2021, one year old breeders (n=61) were reared indoor in controlled environment. Breeders were organized in 7 groups, corresponding to different blood lines; each group included one male and a variable number (3-14) of females. Egg oviposition was started on 24 weeks of age (September 2020) and was recorded daily during the first and second year of age; weekly oviposition rate is presented in Figure 1.1. Data show different cycles of oviposition, the first one 51 weeks long and more efficient, and two further cycles shorter and less efficient in the second year of age. Overall egg production is quite limited, being only 36% the oviposition peak reached in the first year of age.

Project description:Changing predominant SARS-CoV-2 lineages drive successive COVID-19 waves in Malaysia, February 2020 to March 2021
Project description:Between January 2021 and September 2021, a total of 5 pairs of adjacent normal tissues and CRC tumor tissues were collected at Suzhou Municipal Hospital. Written informed consent was secured from all participating patients prior to the commencement of the study. The study protocol, including all experiments, was reviewed and approved by the Ethics Committee of Suzhou Municipal Hospital.
Project description:A multicenter Italian retrospective study on COVID-19 pandemic condition and advanced Gastro - Intestinal Cancer.
Are in Italy increased the new diagnosis of GI cancer in advanced stage in the 2020 compared with 2019, as a consequence of COVID-19?
Project description:Buds were collected at equivalent branch positions and always at the same time of the day. Samples corresponding to May (MAY), June (JUN), July (JUL), September (SEP), November (NOV), January (JAN), March (MAR) and April (APR) buds were analyzed. ****[PLEXdb(http://www.plexdb.org) has submitted this series at GEO on behalf of the original contributor, Jose Diaz-Riquelme. The equivalent experiment is VV36 at PLEXdb.]
Project description:The objective of this study was to characterise the changes in the exosomal miRNA concentrations circulating in the maternal plasma between mothers delivering term and preterm neonates, across gestation using a longitudinal study design. A retrospective stratified study design was used to characterize the miRNA content in exosomes present in maternal plasma of term (n=20 per time point) and preterm birth (PTB) (n=10 per time point) across gestation (i.e. first, second and third trimester).
Project description:Recent improvements in the analysis ancient biomolecules from human remains and associated dental calculus have provided new insights into the prehistoric diet and past genetic diversity of our species. Here we present a “multi-omics” study, integrating genomic and proteomic analyses of two post-Last Glacial Maximum (LGM) individuals from San Teodoro cave (Italy), to reconstruct their lifestyle and the post-LGM resettlement of Europe. Our analyses show genetic homogeneity in Sicily during the Palaeolithic, representing a hitherto unknown Italian genetic lineage within the previously identified “Villabruna cluster”. We argue that this lineage took refuge in Italy during the LGM, followed by a subsequent spread to central-western Europe. Analyses of dental calculus using genomics and proteomics showed a similar oral microbiome composition as Neandertals, but distinct from later foragers and farmers, revealing also a diet based on mammals, fish and plants. Our results demonstrate the power of using a multi-omics approach in the study of prehistoric human populations.
