TL;DR: Using immunophenotyping, RNA sequencing, and serum cytokine analysis, this article analyzed serial samples from 207 SARS-CoV2-infected individuals with a range of disease severities over 12 weeks from symptom onset.
Journal ArticleDOI
Spermadhesin AQN1 Is a Candidate Receptor Molecule Involved in the Formation of the Oviductal Sperm Reservoir in the Pig
Mahnaz Ekhlasi-Hundrieser,Katrin Gohr,Andrea Wagner,Miroslava Tsolova,Anna M. Petrunkina,Edda Töpfer-Petersen +5 more
TL;DR: It is demonstrated that the sperm lectin AQN1 fulfils the criteria for an oviduct receptor in the pig and may play a role in the formation of the oVIDuctal sperm reservoir.
Journal ArticleDOI
Function of the mammalian oviductal sperm reservoir.
Edda Töpfer-Petersen,Andrea Wagner,Julia Friedrich,Anna M. Petrunkina,Mahnaz Ekhlasi-Hundrieser,Dagmar Waberski,Wolfgang Drommer +6 more
TL;DR: Spermadhesins, a new class of animal lectins and the major secretory products of the porcine seminal vesicle, associate with the sperm surface at ejaculation and are candidate molecules for the receptors of the epithelial carbohydrates.
Journal ArticleDOI
Carbohydrate-based interactions of oviductal sperm reservoir formation-studies in the pig.
Andrea Wagner,Mahnaz Ekhlasi-Hundrieser,Christiane Hettel,Anna M. Petrunkina,Dagmar Waberski,Manfred Nimtz,Edda Töpfer-Petersen +6 more
TL;DR: The data indicate that the carboyhdrate‐based mechanisms underlying the formation of the oviductal sperm reservoir in the pig is the result of the concerted action of at least the high‐affinity binding sites for oligomannose or nonreducing terminal mannose residues and low‐Affinity binding of galactose.
Journal ArticleDOI
Vitrification of human ICSI/IVF spermatozoa without cryoprotectants: new capillary technology.
Vladimir Isachenko,R. Maettner,Anna M. Petrunkina,Anna M. Petrunkina,Karl Sterzik,Peter Mallmann,Gohar Rahimi,Raúl Sánchez,Jennie Risopatrón,Ilija Damjanoski,Evgenia Isachenko,Evgenia Isachenko +11 more
TL;DR: The newly developed technology of aseptic vitrification of human spermatozoa in capillaries can effectively preserve these cells from cryo-injures and has a great potential for use in ICSI/IVF.
