The basic aim of this study was to compare the denitrification efficacy of 2,5-dichloroaniline, Ammonium Thiosulphate and their combination (1:1) with previous studies. Ammonium Thiosulphate was not used as a nitrification inhibitor in previous research. Our findings depict that there was significant variation among the chemicals, soil and levels in denitrification for early seedling growth of wheat.

Serum progesterone levels performed prior to oocyte pick-up is commonly used to guide embryo transfer in in-vitro fertilization (IVF) cycles, as elevated levels can negatively influence pregnancy outcomes. However, levels associated with normal pregnancies should trigger clinicians to consider alternative causes such as a pre-existing pregnancy.

The bisexual fertile tetraploid fish is important in biological evolution. Tetraploid fish fertility is the key factor for stable inheritance. Therefore, elucidating tetraploid fish fertility at the molecular level is essential. MicroRNAs regulate gene expression and are involved in many aspects of gonad development.

This study investigates the pesticides atrazine, chlorpyrifos, and dieldrin for endocrine disrupting, phenotypic, and neurobehavioral effects. Zebrafish embryos were exposed to various environmentally relevant concentrations of pesticides during two critical windows, 0-5 days post fertilization (dpf) throughout embryogenesis and 4- 5 dpf at early larval development.

The obtained results showed that the irrigation treatments (3 events) gave the lowest values for water consumptive use, grain, straw, biological yield and 1000-grain weight. Nitrogen fertilizer in ammonia up to 90 kg N fed
1 decreased all characters studied except grain yield which has no any significant differences between both N levels.

Reactive oxygen species (ROS) are byproducts of normal plant metabolism and their production is elevated under environmental stresses such as drought, extreme temperature, and salinity. Among these, salinity is a worldwide problem that impacts the fertility of arable lands and sustainability of food security, which is getting more attention due to climate change. Halophytes can survive and reproduce in soils containing high concentrations of salt and have developed adaptation mechanisms at physiological, biochemical, and molecular levels including maintenance of ROS metabolism.

This study included 22 women in intracytoplasmic sperm injection cycle. The expression of olfactory target molecules in cumulus cells surrounding the growing and mature oocytes was evaluated by Western blotting and real-time polymerase chain reaction. Additionally, integrated bioinformatics analyses were carried out and 6 ectopic olfactory receptors were selected for further evaluation. The initiation of olfactory transduction cascade in cumulus cells of competent oocytes was confirmed by analyzing the expression of adenylyl cyclase type 3 and olfactory market protein.

Negative energy balance (NEB) is an imbalance between energy intake and energy requirements for lactation and body maintenance affecting high-yielding dairy cows and is of considerable economic importance due to its negative impact on fertility and health in dairy herds. It is anticipated that the cow hypothalamus experiences extensive biochemical changes during the early post partum period in an effort to re-establish metabolic homeostasis. However, there is variation in the tolerance to NEB between individual cows.

Cytoplasmic male sterility (CMS) and its restoration of fertility (Rf) system is an important mechanism to produce F1 hybrid seeds. Understanding the interaction that controls restoration at a molecular level will benefit plant breeders. The CMS is caused by the interaction between mitochondrial and nuclear genes, with the CMS phenotype failing to produce functional anthers, pollen, or male gametes.

MicroRNAs (miRNAs) are a class of noncoding small RNAs that play important roles in many physiological processes by regulating gene expression. Previous studies have shown that the expression levels of total miRNAs increase during mouse embryonic development, and some miRNAs control the regulatory network in development progression.

High levels of polyunsaturated fatty acids in chicken spermatozoa make them susceptible to lipoperoxidation and reduce their fertility. This study was conducted to assess the effect of sesame seed suplementation in the diet on the semen quality of Ho cocks. Eighteen 13-14 month-old cocks were randomly divided into three groups and were assigned to one of the following treatments: 0% SS (control), 5% SS, or 7% sesame seeds per kg of diet for ten consecutive weeks after a two-week adaptation period. Semen characteristics were evaluated once a week.
