Semen cryopreservation damages sperm due to oxidative stress. This study evaluated the antioxidant capacity of Moringa oleifera seed extract in cryopreserved ram semen and impact on characteristics. from eight hair rams (four per sampling) was allocated into four groups, according their treatment prior cryopreservation: Control (no extract), 0.5 (M0.5), 5.0 (M5.0), 10.0 (M10) mg/mL M. extract. The activity (ferric reducing power, FRAP) spermatic characteristics (sperm viability; progressive...
Human-driven climate change generates extreme weather events, a well-known consequence of global warming. This leads to increased exposure most living beings higher temperatures, resulting in longer, more frequent, and intense heat stress (HS) periods. jeopardizes the welfare survival animals, negatively affecting process that connects generations ensures subsistence natural selection: reproduction. letter aims draw attention impact increasing HS on animal reproductive capacity potential...
SUMMARY Mammalian embryos that rapidly reach the two‐cell stage in culture have a higher probability of becoming viable blastocysts. Our goal was to separate bovine based on their zygotic cleavage timing, and assess global mRNA levels. Following vitro fertilization, all cleaved by 29.5 hpi (early) were cultured separately from those divided at 46 (late). The blastocyst rates 46.1 ± 3.7% 6.1 3.4% for early‐ late‐cleavers, respectively ( P < 0.01). Seven replicates selected collected each...
The effect of elicitation in butterhead lettuce on carotenoid and polyphenol metabolism was evaluated. Different concentrations arachidonic acid (AA), salicylic (SA), methyl jasmonate (MJ) (15, 45, 90 μM) Harpin protein (HP) (30, 60, 120 mg/L) were applied red green lettuces. Total phenolic flavonoid content incremented by MJ (90 lettuce. Carotenoids increased (AA; 45 μM). Green modifies their profile after with AA MJ; meanwhile, mainly hydroxycinnamic acids flavonols, being the elicitor...
The sequence of a 3′ untranslated region (3′UTR) mRNA governs the timing its polyadenylation and translation in mammalian oocytes early embryos. objective this study was to assess influence cis ‐elements 3′UTR developmentally important ATF1 ATF2 transcripts on their timely during first cleavages bovine Eight different reporter mRNAs (coding green fluorescent protein [ GFP ] fused short or long isoforms cattle ‐ 2 , with without polyadenylation) control were microinjected separately into...
Cryopreservation has adverse effects on the post-thaw sperm quality due to oxidative stress and presence of bacteria. To minimize such effects, plant extracts have been included in composition semen diluents. The objective present study was evaluate antimicrobial antioxidant Moringa oleifera seed extract (MOSE) cryopreserved ram semen, as well its impact vitro fertilization. Semen from six hair rams treated with five treatments before cryopreservation: Control (without any antibiotic),...
During germline establishment and its molecular control, the Figla gene, which codes a transcription factor, is preferentially expressed in oocytes, key for oogenesis/folliculogenesis, ovarian function, female fertility. However, specific subcellular localization (cytoplasmic or nuclear) of this factor unknown. We analyzed FIGLA protein using computer programs NucPred, SubCellProt, NLStradamus to predict localization; also, we established platform artificial expression murine gene cultured...
La retención placentaria (RP) es uno de los trastornos reproductivos más comunes que afecta a las vacas lecheras; sin embargo, factores riesgo no están completamente establecidos. El objetivo fue determinar la relación entre diferentes para PR en el norte México. Se utilizaron registros productivos 2,483 Holstein Ciudad Juárez, Chihuahua, Las variables se analizaron mediante una prueba X2. calcularon razones momios (odds ratio; OR) y realizó un análisis correlación canónica influencia con RP...
The period of both in vitro maturation (IVM) and incubation with oocyte activators affects the blastocyst yield following parthenogenetic activation (PA). Nevertheless, it is still unknown how these conditions impact expansion hatching rates bovine blastocysts. objective this study was to assess influence duration IVM exposure activating agent, 6-dimethylaminopurine (6-DMAP), on a number developmental parameters parthenotes, including: Cleavage, formation, expansion, hatching. Slaughterhouse...
Objective: To test whether HTF (Human Tubal Fluid) is capable of protecting goat sperm cells increasing the semen m determine if can protect buck cells, motility when used by itself or combined with Andromed® commercial extender. Design/Methodology/Approach: The eight bucks Boer breed was (10 ejaculates per male). Each ejaculate diluted in three treatments (5 repetitions treatment): 1) only Andromed®; 2) HTF; and 3) + HTF. following variables were evaluated: mass (MM) progressive (MP) fresh...
The ashwin gene in Xenopus is expressed the neural plate, and later embryonic brain, eyes, spinal cord, regulates cell survival during gastrulation anterioposterior patterning. also maternally zygotically expressed, suggesting its importance embryo development. Here, bovine ASHWIN homolog was isolated from an ovary cDNA library. expression analysis of this by RT-PCR adult heart, lung, muscle, ovary, testis demonstrated ubiquitous 699 bp transcript. Interestingly, tissues showed two...
