We examined the effects of culture and ethnicity on life history strategies in terms of sexual and reproductive behaviors. The sample included 500 adults, aged 25-50 years, from the five major ethnic groups in Suriname, i.e., the Maroons, Creoles, Hindustani, Javanese, and Mixed. First, there were strong gender differences: men reported to have had more sex partners and to have had their first sexual experience earlier than women, whereas women had their first child earlier and had more children than men. Second, in general, ethnicity affected life history substantially. The Maroons stood out by a relatively fast life history: they reported to have had more sexual partners, to have had their first sex and first child at an earlier age, and to have more children than all other groups. The Creoles were in general similar to the Maroons, whereas the Hindustani and the Javanese were characterized by a relatively slow life history: they reported to have had the lowest number of sexual partners, to have had their first sex and first child at the latest age, and to have had the lowest number of children. The differences between the ethnic groups were upheld when controlling for income, educational level, and father absence during childhood. A lower education was associated with reporting to have had one's first sex as well as one's first child at a younger age and children who grew up without a father reported to have had their first sex at a younger age.

Purpose: To employ a validated survey for evaluation of quality of life (QoL) outcomes and associated factors in a US cohort of adult patients with acquired anophthalmia wearing a prosthesis.
Methods: A retrospective cohort study was performed at a single, US academic institution of patients cared for between 2012 and 2021. The electronic medical record database was queried for adult patients with a history of evisceration or enucleation surgery and placement of an orbital implant.

The evolutionary relationships between species are typically represented in the biological literature by rooted phylogenetic trees. However, a tree fails to capture ancestral reticulate processes, such as the formation of hybrid species or lateral gene transfer events between lineages, and so the history of life is more accurately described by a rooted phylogenetic network. Nevertheless, phylogenetic networks may be complex and difficult to interpret, so biologists sometimes prefer a tree that summarises the central tree-like trend of evolution.

During the transition from fresh waters to terrestrial habitats, significant adaptive changes occurred in kidney function of vertebrates to cope with varying osmotic challenges. We investigated the mechanisms driving water conservation in the mammalian nephron, focusing on the relative contributions of active ion transport and Starling forces. We constructed a thermodynamic model to estimate the entropy generation associated with different processes within the nephron, and analyzed their relative importance in urine formation.

Introduction And Hypothesis: The objective of our study is to investigate the presence of lower urinary tract symptoms (LUTS) and its correlation with the risk of falling in older women with cognitive frailty.
Methods: The descriptive study was conducted on 102 female older adults, 60 women were classed as cognitively frail and 42 as healthy. Women were classified as having mild cognitive impairment based on the Clinical Dementia Rating Scale and as frail based on the Clinical Frailty Scale.

Objectives: To investigate the pathogenicity of feline herpesvirus-1 (FHV-1) to the cornea, FHV-1 strains isolated from feline eyes with dendritic ulcers were subjected to genomic analysis to determine whether FHV-1 vaccine strains are involved in the formation of dendritic ulcers.
Methods: All open reading frame (ORF) sequences of the three F2 strains (Virbac, Intervet and Merial) and the FHV-1 clinical isolates from cats registered in GenBank were compared to detect nucleotide variants unique to the F2 strains, with those nucleotides then being used for simple genotyping of the F2 strains. In all isolates from feline eyes with dendritic ulcers, the regions including nucleotide variants of the F2 strain were amplified with PCR and sequenced.
