Disposal and utilization of dead animals during breeding in livestock and poultry farming by means of synthetic microbiota.

The disposal of animal remains resulting from breeding is a significant challenge that impacts the industry's growth. To address the issues with current treatment methods, such as the large space required for corpse storage, and the high energy consumption of pyrolysis. Three strains with high protease and lipase production and one strain with high keratinase production were screened.

Menstrual abnormalities effects on clinical features and in vitro fertilization pregnancy outcomes in women with polycystic ovarian syndrome.

Background: The diagnostic criteria and phenotypes in polycystic ovary syndrome are heterogeneous. Currently, it is unclear how to assess a patient's prognosis based on the onset time of menstruation disturbance. Evidence on this topic is scarce and has mainly focused on menstrual patterns.

The difference in early trimester fetal growth between singletons after frozen embryo transfer and fresh embryo transfer.

Background: Frozen embryo transfer resulted in a higher birthweight and an increased risk of macrosomia than fresh embryo transfer. However, the mechanism was still unclear. When the impact of frozen embryo transfer on fetal growth began was unknown.

Interpregnancy Interval After Clinical Pregnancy Loss and Outcomes of the Next Frozen Embryo Transfer.

Importance: The optimal interpregnancy interval (IPI) after a clinical pregnancy loss (CPL) remains controversial. Few studies have addressed the role of the IPI after a preceding CPL during in vitro fertilization (IVF) treatment.

Objective: To evaluate the association between different IPI lengths after a preceding CPL and pregnancy outcomes of the next frozen embryo transfer (FET).
