K-means segmentation based-on lab color space for embryo detection in incubated egg [PDF]
J. Ilm. Tek. Elektro Komput. dan Inform., 2022, Vol. 7, No. 2, p.
175-185, 2021 The quality of the hatching process influences the success of the hatch rate besides the inherent egg factors. Eliminating infertile or dead eggs and monitoring embryonic growth are very important factors in efficient hatchery practices. This process aims to sort eggs that only have embryos to remain in the incubator until the end of the hatching ...

Yolk sac tumors of the ovary [PDF]
Cancer, 1970 Eighteen instances of ovarian tumor with microscopic pattern similar to that of the testicular tumors which we termed yolk sac or vitelline are presented. In the ovary, though not in the testis, this pattern has often been called “Schiller mesonephroma.” Reasons are given for our preference for the term yolk sac tumor to that of mesonephroma for these ...

Fate-Mapping of Yolk Sac-Derived Macrophages [PDF]
, 2023 To better understand the distinct functions of yolk-sac-derived tissue-resident macrophages (TRMs) and bone-marrow-derived macrophages in homeostasis and disease, it is important to trace the ontogeny of these cells.

Yolk sac tumors of the testis [PDF]
Cancer, 1970 The discovery of 2 yolk sac carcinomas of the mouse has established a basis in comparative pathology for the occurrence of this type of tumor in other species with yolk sacs. Grafts and tissue cultures of extra-embryonic yolk sac of the mouse have developed a clear understanding of the types of tissues one might expect in yolk sac carcinomas.

Ovarian yolk sac tumor in postmenopausal females
Medicine, 2018 Rationale: Ovarian yolk sac tumors (YSTs) are the second most common histologic type of ovarian germ cell tumors. Most patients are adolescent and young women, while cases in postmenopausal women were rarely reported.

A sinonasal yolk sac tumor in an adult [PDF]
Journal of Pathology and Translational Medicine, 2022 Yolk sac tumors (YSTs), which are also called endodermal sinus tumors, are malignant tumors of germ cell origin. These tumors usually occur in the gonads, but 20% of cases have been reported at extragonadal sites. The head and neck is a rarely affected region that accounts for just 1% of all malignant tumors of germ cell origin. In addition, YSTs arise
