Studies on the sperm reservoir of the pig oviduct [PDF]

, 2003
During sperm transport in the female pig a proportion of spermatozoa are arrested, often for 24 h or more, in a particular segment of the utero-tubal junction (UTJ) and the adjacent tubal isthmus, where a sperm reservoir (SR) is built up.

Advancements in Alginate‐Based Biomaterials for Enhanced Skin Regeneration: A Comprehensive Review

International Journal of Polymer Science, Volume 2026, Issue 1, 2026.
Alginate, a naturally occurring polysaccharide composed of β‐d‐mannuronate (M) and α‐l‐guluronate (G), has attracted widespread attention for skin regeneration applications due to its exceptional biocompatibility, biodegradability, and tunable physicochemical properties. Beyond its traditional role in maintaining a moist wound environment and providing

The effect of the staining technique on morphological and morphometric parameters of boar sperm

PLoS ONE, 2019
Sperm morphology and morphometry are important parameters in predicting fertility. Sperm are considered to be normal if the shape and size of the head, midpiece and tail fall within the classification for a given species.

Application of seminal plasma in sex-sorting and sperm cryopreservation [PDF]

, 2008
Substantial dilution of boar semen during processing decreased the concentration of seminal plasma, perhaps contributing to the decline in sperm quality after cryopreservation and sex-sorting.

Contrasted effects of temperate forest closure on snake demography

Ecosphere, Volume 16, Issue 12, December 2025.
Abstract Habitat modification is the main threat to biodiversity, but other causes are involved, such as climate change or pollution. To optimize conservation efforts, it is crucial to determine their respective contributions. An effective approach to disentangle causalities is to set up comparative or experimental monitoring in the field.

Expanding Horizons: Next‐Generation and Interdisciplinary Advances in the Applications of Extracellular Vesicles

Journal of Extracellular Biology, Volume 4, Issue 12, December 2025.
ABSTRACT Extracellular vesicles (EVs) are increasingly recognized as universal mediators of communication in nature across all domains of life and as versatile tools with roles spanning a wide range of industries. Although EVs have been extensively studied in biomedicine, mainly in diagnostic and nanotherapy of cancer and neurodegenerative diseases ...
