In this paper we systematically describe the connection between immigration and fertility in light of the increasing nativist reaction to Hispanic groups. We follow a life-course perspective to directly link migration and fertility transitions. The analysis combines original qualitative and quantitative data collected in Durham/Chapel Hill, NC as well as national level information from the Current Population Survey. The qualitative data provides a person-centered approach to the connection between migration and fertility that we then extend in quantitative analyses. Results demonstrate that standard demographic measures that treat migration and fertility as separate processes considerably distort the childbearing experience of immigrant women, inflating fertility estimates for Hispanics as a whole. Once this connection is taken into consideration the fertility levels of Hispanic women are much lower than those reported with standard measures and the fertility-specific contribution of Hispanics to U.S. population growth is much reduced.

Colorectal Cancer (CRC) is a significant global health issue, being the third most common cancer worldwide and the second most frequent cause of cancerrelated deaths. It occurs when cells in the colon or rectum grow uncontrollably, often developing from precancerous polyps. Genetic predisposition and environmental factors, such as diet and lifestyle, contribute to the disease.

Germ cells are essential for fertility, embryogenesis, and reproduction. Germline development requires distinct types of germ granules, which contains RNA-protein (RNP) complexes, including germ plasm in embryos, piRNA granules in gonadal germ cells, and the Balbiani body (Bb) in oocytes. However, the regulation of RNP assemblies in zebrafish germline development are still poorly understood.

Long non-coding RNAs (lncRNAs) play vital roles in the development and progression of various tumors through multiple mechanisms. Among these, HOTTIP (HOXA transcript at the distal tip) stands out as an intriguing candidate with diverse functions in several malignancies, including breast cancer and gynecologic cancers such as ovarian, cervical, and endometrial cancers, which are significant global health concerns. HOTTIP interacts with key signaling pathways associated with these cancers, including Wnt/β-catenin, PI3K/AKT, and MEK/ERK pathways, enhancing their activation and downstream effects.

Background: Premature ovarian insufficiency (POI) is a refractory disease that severely affects female fertility. The PERK/eIF-2α/ATF4/CHOP pathway is one of the classical pathways involved in the unfolded protein response to endoplasmic reticulum stress by regulating protein synthesis and promoting apoptosis. This study aimed to investigate the functional role and mechanism of human umbilical cord mesenchymal stem cells (hUCMSCs) in the POI animal model through the PERK/eIF-2α/ATF4/CHOP pathway.

Prospermatogonia (ProSGs), the progenitors of spermatogonial stem cells in neonatal testes, undergo critical migration to the testicular microenvironment-a fundamental process for testicular development and subsequent spermatogenic capacity. The SDF-1/CXCR4 chemokine axis serves as an essential molecular guidance mechanism, directing ProSGs toward the basal membrane of seminiferous tubules. Nevertheless, the precise molecular mechanisms governing this axis remain incompletely understood.
