This paper considers the role which the demographic parameters of fertility, mortality and migration will play on the pace and concentration of aging within the context of a developing region. This paper examines the demographic transition and analyzes historic and projected data for the development patterns of the anglophone nation states of the Caribbean. Trends in fertility, mortality, and migration are contrasted among the larger (Guyana, Jamaica, Trinidad/Tobago), mid-sized (Bahamas, Barbados, Belize) and smaller (Antigua/Barbuda, Dominica, Grenada, St Kitts/Nevis, St Lucia, and St Vincent/Grenadines) states. The paper then goes on to consider shifts in the structure of population at older ages due to the decline in fertility and mortality and points to some of the policy considerations that these relatively small and newly independent states will need to deal with during the next several decades.

Fertility preservation services must offer information to patients, prior to their visit, so that they have time to read and digest the information, and also have the opportunity to write down any questions they wish to ask at the oncofertility consultation appointment. Appointments must be offered immediately, based on a specifically designed referral form. Each fertility service providing oncology cryopreservation should have a robust map of the patient's journey to include referral, counseling session, medical consultation, informed consent, treatment plan, and follow-up.

Research investigating association between patriarchy and demographic behavior is limited in India. The only study on this subject utilized 1981 Indian Census data to examine associations between patriarchy and fertility. We examined the association of patriarchy, measured using India Patriarchy Index (IPI), with total fertility rate (TFR) and excess female child mortality in India.

Non-small cell lung adenocarcinoma (LUAD) is a markedly heterogeneous disease, with its underlying molecular mechanisms and prognosis prediction presenting ongoing challenges. In this study, we integrated data from multiple public datasets, including TCGA, GSE31210, and GSE13213, encompassing a total of 867 tumor samples. By employing Mendelian randomization (MR) analysis, machine learning techniques, and comprehensive bioinformatics approaches, we conducted an in-depth investigation into the molecular characteristics, prognostic markers, and potential therapeutic targets of LUAD.

The objective of this study was to evaluate the impact of feeding broiler breeders hydroxychloride and organic sources of zinc (Zn), copper (Cu), and manganese (Mn) on hatching eggs, embryo, and hatchlings attributes. A total of 408 female (♀) and 48 male (♂) Ross 708 broiler breeder were placed (17 ♀ and 2 ♂/pen). The pens were housed in two rooms (12 pens/room).

Multiple mating is a behaviour observed across various polyandrous insect species. It is suggested that, in ladybirds, this strategy of multiple copulations is used to enhance fecundity and fertility through sperm replenishment. Studies on sperm depletion need to correlate fertility with the presence of spermatozoa in the spermatheca.
