Selective disappearance based on navigational efficiency in a long-lived seabird.

Whilst efficient movement through space is thought to increase the fitness of long-distance migrants, evidence that selection acts upon such traits remains elusive. Here, using 228 migratory tracks collected from 102 adult breeding common terns (Sterna hirundo) aged 3-22 years, we find evidence that older terns navigate more efficiently than younger terns and that efficient navigation leads to a reduced migration duration and earlier arrival at the breeding and wintering grounds. We additionally find that the age-specificity of navigational efficiency in adult breeding birds cannot be explained by within-individual change with age (i.

In this study, a relationship between climate indices (local - air temperatures, and wide-scale - North Atlantic Oscillation) and first arrival dates (FAD) of a short-distant migratory bird, the Common Wood Pigeon (Columba palumbus) at a breeding site in SE Poland (Lublin) was investigated. Temporal patterns of FAD on a multi-year scale (20 years within 39 years between 1982 and 2020) were also studied. Additionally, correlations between mean air temperature at Lublin and sites along the spring migration route with various distances from the breeding site and various time lags were searched for.

Immunity suffers a function deficit during aging, and the incidence of cancer is increased in the elderly. However, most cancer models employ young mice, which are poorly representative of adult cancer patients. We have previously reported that Triple-Therapy (TT), involving antigen-presenting-cell activation by vinorelbine and generation of TCF1-stem-cell-like T cells (scTs) by cyclophosphamide significantly improved anti-PD-1 efficacy in anti-PD1-resistant models like Triple-Negative Breast Cancer (TNBC) and Non-Hodgkin's Lymphoma (NHL), due to T-cell-mediated tumor killing.

Partial stenosis of the renal artery causes renovascular hypertension (RVH) and is accompanied by chronic renal ischemia, resulting in irreversible kidney damage. Revascularization constitutes the most efficient therapy for normalizing blood pressure (BP) and has significant benefits for renal function; however, the tissue damage caused by chronic hypoxia is not fully reversed. Mesenchymal stem cells (MSCs) have produced discrete results in minimizing RVH and renal tissue and functional improvements since the obstruction persists.

Department of Dentistry, Faculty of Health Sciences, Universidad Fernando Pessoa Canarias, Santa María de Guía, Gran Canaria, Spain.
This descriptive study focuses on the oral health of African migrants, especially adolescents, arriving in the Canary Islands. Notably, these patients show a high prevalence of caries and oral mucosal alterations. These are influenced by multifactorial factors, such as living conditions in their country of origin, hygiene habits, and sugar-rich diets.
