Evaluation of testicular sperm CRISP2 as a potential target for contraception
(American Society of Andrology, 2012-11-12)
Cysteine-rich secretory protein 2 (CRISP2) is a testicular sperm protein proposed to be involved in fertilization. With the aim of examining the relevance of CRISP2 for fertility and its potential use as a target for ...
Cholesterol Depletion Disorganizes Oocyte Membrane Rafts Altering Mouse Fertilization
(Public Library of Science, 2013-04-25)
Drastic membrane reorganization occurs when mammalian sperm binds to and fuses with the oocyte membrane. Two oocyte protein families are essential for fertilization, tetraspanins and glycosylphosphatidylinositol-anchored ...
Regional model for nitrogen fertilization of site-specific rainfed corn in haplustolls of the central Pampas, Argentina
(Springer, 2011-12)
In semi-arid regions, soil water and nitrogen (N) are generally limiting factors for corn (Zea mays L.) production; hence, implementation of appropriate N fertilization strategies is needed. The use of precision agriculture ...
Epididymal protein CRISP1 plays different roles during the fertilization process
(American Society of Andrology, 2011-11)
Rat epididymal CRISP1, the first described member of the evolutionarily conserved Cysteine-RIch Secretory Protein (CRISP) family, is expressed in the proximal regions of the epididymis and associates with the sperm during ...
Impaired male fertility and abnormal epididymal epithelium differentiation in mice lacking CRISP1 and CRISP4
(Nature Publishing Group, 2018-12)
Epididymal Cysteine Rich Secretory Proteins 1 and 4 (CRISP1 and CRISP4) associate with sperm during maturation and play different roles in fertilization. However, males lacking each of these molecules individually are ...
DTPA-extractable zinc threshold for wheat grain yield response to zinc fertilization in Mollisols
(Soil Science Society of America, 2021-09)
Determining soil Zn thresholds for wheat (Triticum aestivum L.) is still challenging because soil Zn tests have been poorly calibrated. Therefore, this work aimed to determine, under field conditions, the diethylenetriam ...
Bottom-up effect of nitrogen fertilization on the density of the corn leafhopper and its impact on both disease incidence and natural parasitism
(Springer, 2022-04-15)
The corn leafhopper Dalbulus maidis is a specialist herbivore that attacks maize in the tropical and subtropical regions of the Americas. It is the vector of three relevant plant pathogens that are responsible for severe ...
Successful capacitation and homologous fertilization in vitro in Calomys musculinus and Calomys laucha (Rodentia, Sigmodontinae)
(Portland Press, 2000-02)
Small South American rodents of the genus Calomys have been used extensively for virology and ecological research. Previous studies have demonstrated that Calomys musculinus and Calomys laucha have a relatively short ...
Evaluación de subfertilidad y fertilidad en alpacas adultas y tuis mediante ultrasonografÍa, citologÍa endometrial y aislamiento bacterianoEvaluation of fertility and subfertility in adult alpacas and tuis using ultrasonography, endometrial cytology and bacterial isolation
(Asociacion Peruana de Reprouduccion Animal, 2020-12)
The objective of this study was to compare the uterine health between fertile, sub-fertile alpacas and tuis using transrectal ultrasonography, endometrial cytology and bacterial isolation. A total 10 tuis (young mature ...
DTPA-extractable zinc threshold for wheat grain yield response to zinc fertilization in Mollisols
(Wiley, 2021-06)
Determining soil Zn thresholds for wheat (Triticum aestivum L.) is still challenging since soil Zn tests have been poorly calibrated. Therefore, this work aimed to determine, under field conditions, the DTPA-Zn critical ...
