A Comprehensive Analysis of the Nutritional Value, Antioxidant Potential and Fatty Acid Composition of Lucuma (Pouteria lucuma) Fruit, Grown in the High-Altitude Valleys of Bolivia.

The lucuma tree (Pouteria lucuma), native to South America, is gaining attention for its unique nutritional profile and potential health benefits. This study aimed to analyze the nutritional composition, antioxidant capacity, and fatty acid profile of lucuma fruit from a high-altitude valley in Bolivia. The proximate analysis revealed high levels of carbohydrates (41.

Lonesome plants: How isolation affects seed set of a threatened dioecious shrub.

Plant reproductive failure is a critical concern for conserving rare and endangered species that typically have low-density and sparse populations. One important factor contributing to reproductive failure is the spatial arrangement of plants within a population, which can lead to isolation and negatively affect seed production, particularly in obligate outcrossers. Additionally, plant size can compound this effect, influencing seed production via multiple processes.

Prevalence of Fabry disease in patients with chronic kidney disease: A systematic review and meta-analysis.

Fabry disease (FD) is an X-linked lysosomal storage disease caused by pathogenic variants in the GLA gene. It has a wide range of clinical manifestations, typically related to the specific underlying GLA variant. One of the main features of FD is kidney involvement; therefore, several studies have addressed the prevalence of FD in all types of patients with chronic kidney disease.

Dormancy-break and germination requirements for seeds of the threatened Austral papaya (Carica chilensis).

Seed dormancy is one of the most important adaptive mechanisms in plants, optimizing germination, seedling emergence, and establishment to ensure these processes occur when environmental conditions are favorable for plant survival and growth. Endemic to rocky environments of the southern Atacama Desert, the Austral papaya (Carica chilensis) is the papaya species with the southernmost distribution within the Caricaceae, thriving in the most extreme environmental conditions. This threatened plant exhibits low natural regeneration, primarily attributed to low germination, yet no information regarding seed dormancy release is available.

Detailed whole-body nutrient analysis identifies differences in feeding ecology between related fish species: The case of Orestias native Andean killifish in Lake Titicaca.

Body nutrient profiles in ecological studies allow for relating the nutritional status of consumers and their effects on the movement and retention of elements in ecosystems, as well as reflecting feeding conditions and habitat quality. This study compared the detailed whole-body nutrient composition (macronutrients, minerals, fatty acids and amino acids) of two omnivorous natives Orestias killifish from Lake Titicaca (Orestias agassizii and Orestias luteus, Valenciennes), the largest lake in the Andes, as an indirect tool to understand differences in their feeding ecology. Although both species are usually described as omnivorous fish, both have amphipods (Hyalella spp) as their main food source.

Evidence of microplastics in water and commercial fish from a high-altitude mountain lake (Lake Titicaca).

Microplastic pollution is a widespread environmental concern. Like other anthropogenic pollutants, microplastics can reach aquatic ecosystems through rivers and interact with the aquatic biota. For instance, Lake Titicaca (between Bolivia and Peru), one of the great ancient lakes in South America (3,809 m a.
