  • Low concentrations of 3-O-methylglucose improve post thaw recovery in cryopreserved bovine spermatozoa. [Journal Article]
    Cryobiology. 2020 Jun 30 [Online ahead of print]Bhat MH, Blondin P, … Benson JD
  • A number of studies have explored the use of membrane permeable (usually metabolizable) and membrane impermeable saccharides to protect cells in general, and sperm in particular during cryopreservation. Critical concentrations for protective levels of sugars frequently range between 50 mmol/L and 500 mmol/L, where efficacy is attributed to the sugar's membrane stabilizing and glass forming attrib…
  • Naive Human Embryonic Stem Cells Can Give Rise to Cells with a Trophoblast-like Transcriptome and Methylome. [Journal Article]
    Stem Cell Reports. 2020 Jun 23 [Online ahead of print]Cinkornpumin JK, Kwon SY, … Pastor WA
  • Human embryonic stem cells (hESCs) readily differentiate to somatic or germ lineages but have impaired ability to form extra-embryonic lineages such as placenta or yolk sac. Here, we demonstrate that naive hESCs can be converted into cells that exhibit the cellular and molecular phenotypes of human trophoblast stem cells (hTSCs) derived from human placenta or blastocyst. The resulting "transdiffe…
  • Paternal nutrient provisioning during male pregnancy in the seahorse Hippocampus abdominalis. [Journal Article]
    J Comp Physiol B. 2020 Jul 02 [Online ahead of print]Skalkos ZMG, Van Dyke JU, Whittington CM
  • Vertebrates that incubate embryos on or within the body cavity exhibit diverse strategies to provide nutrients to developing embryos, ranging from lecithotrophy (solely yolk-provided nutrition) to substantial matrotrophy (supplemental nutrients from the mother before birth). Syngnathid fishes (seahorses, pipefishes and sea dragons) are the only vertebrates to exhibit male pregnancy. Therefore, th…
  • The adaptability of Hy-Line Brown laying hens to low-phosphorus diets supplemented with phytase. [Journal Article]
    Poult Sci. 2020 Jul; 99(7):3525-3531.Ren Z, Sun W, … Yang X
  • Body phosphorus homeostasis network allows laying hens to adapt to wide range of changes in dietary phosphorus levels. Phytase hydrolyzes phytate rendering phosphorus and reduces the laying hens' requirements for inorganic phosphate rock. Here, we demonstrate that there is no need to keep large safety margins in dietary phosphorus when hens are fed with phytase. Hy-Line Brown laying hens (n = 504…
  • Embryonic circulating endothelial progenitor cells. [Review]
    Angiogenesis. 2020 Jul 01 [Online ahead of print]Díaz Del Moral S, Barrena S, … Carmona R
  • The development of vascular system in vertebrates has been traditionally explained by early vasculogenic assembly of angioblasts followed by angiogenic outgrowth of pre-existing vessels. The discovery of adult endothelial progenitor cells (Asahara et al. in Science 275(5302):964-967, 1997) challenged this view, since postnatal vascular growth could be accomplished by recruitment of circulating ce…
  • Long Non-coding RNA and mRNA Profile of Liver Tissue During Four Developmental Stages in the Chicken. [Journal Article]
    Front Genet. 2020; 11:574.Ning C, Ma T, … Li D
  • The liver is the major organ of lipid biosynthesis in the chicken. In laying hens, the liver synthesizes most of the yolk precursors and transports them to developing follicles to produce eggs. However, a systematic investigation of the long non-coding RNA (lncRNA) and mRNA transcriptome in liver across developmental stages is needed. Here, we constructed 12 RNA libraries from liver tissue during…
  • Crocin Improves the Quality of Cryopreserved Goat Semen in Different Breeds. [Journal Article]
    Animals (Basel). 2020 Jun 26; 10(6)Longobardi V, Zullo G, … Neglia G
  • The effect of crocin in the semen extender before cryopreservation was evaluated on sperm parameters of 20 bucks of five different breeds: Garganica (GA), Jonica (JO), Maltese (MA), Mediterranean Red (MR) and Saanen (SA). Semen samples were centrifuged, to remove seminal plasma, divided in two aliquots and diluted with Tris-egg-yolk-based extender, containing 0 (control group) and 1 mM crocin. Cr…
  • A Yolk-Shell Structured FePO4 Cathode for High-Rate and Long-Cycling Sodium-Ion Batteries. [Journal Article]
    Angew Chem Int Ed Engl. 2020 Jun 30 [Online ahead of print]Zhou X, Zhang Z, … Shen J
  • Amorphous iron phosphate (FePO 4 ) has attracted enormous attention as a promising cathode material for sodium-ion batteries (SIBs) because of its high theoretical specific capacity and superior electrochemical reversibility. Nevertheless, the low rate performance and rapid capacity decline seriously hamper its implementation in SIBs. Herein, we demonstrate a sagacious multi-step templating appro…
  • Comparison of the quality of cage and organic eggs available in retail and their content of selected macroelements. [Journal Article]
    Acta Sci Pol Technol Aliment. 2020 Apr-Jun; 19(2):159-167.Banaszewska D, Biesiada-Drzazga B, … Kaim-Mirowski S
  • CONCLUSIONS: The research results indicate a slightly better quality of eggs from the organic farm compared to eggs from cages in the case of most physical properties, as well as the content of macro-elements. Eggs in both systems are produced following scientific management practices. There are many myths among consumers regarding the nutritional quality of eggs produced in different systems. This information can be useful for raising awareness among consumers selecting eggs.
  • Primary yolk sac tumor of orbit: Report of a rare case. [Case Reports]
    Indian J Cancer. 2020 Jun 22 [Online ahead of print]Poflee SV, Pawar PS, … Raut WK
  • Extragonadal germ cell tumors (GCTs) of head and neck region account for 5% of all benign and malignant GCTs. Orbit is an uncommon site for occurrence of extragonadal GCTs. Pure yolk sac tumor (YST) of orbit is a rare neoplasm and only a few cases are reported in the literature. An 18-month-old boy presented with right eye proptosis of 2 months duration. Because of rapid clinical course and magne…
  • The Effect of Different Levels of Dietary Magnesium on Eggshell Quality and Laying Hen's Performance. [Journal Article]
    Biol Trace Elem Res. 2020 Jun 25 [Online ahead of print]Belkameh MM, Sedghi M, Azarfar A
  • This study aimed to investigate the effects of different levels of dietary magnesium (Mg) on eggshell quality and laying hen's performance. Four dietary treatments including a commercial-type basal diet containing 3.19 g/kg Mg and three additional diets supplemented with 2, 4, or 6 g/kg magnesium oxide (MgO) to provide 4.03, 4.87, or 5.71 g/kg Mg were used in a completely randomized design. A tot…
  • De novo Synthesis of SAA1 in the Placenta Participates in Parturition. [Journal Article]
    Front Immunol. 2020; 11:1038.Gan XW, Wang WS, … Sun K
  • Serum amyloid A1 (SAA1) is an acute phase protein produced mainly by the liver to participate in immunomodulation in both sterile and non-sterile inflammation. However, non-hepatic tissues can also synthesize SAA1. It remains to be determined whether SAA1 synthesized locally in the placenta participates in parturition via eliciting inflammatory reactions. In this study, we investigated this issue…
