Sensory Biology of the Franciscana (Pontoporia blainvillei, Pontoporiidae, Cetartiodactyla): Ontogenetic Modifications of Vibrissae and Vibrissal Crypts

open access: yesIntegrative Zoology, EarlyView.
The transition of cetaceans from a terrestrial to an aquatic environment involved a crucial sensory adaptation to environments with limited visibility. Vibrissae, important mechanoreceptors, undergo an ontogenetic transformation in odontocetes. This research describes the histomorphology of vibrissae and crypts at different developmental stages ...

Hyperactivation and Tyrosine Phosphorylation of Cryopreserved Stallion Spermatozoa in Relation to Conventional In Vitro Fertilization Blastocyst Production

open access: yesAndrology, EarlyView.
ABSTRACT Background Challenges in establishing clinical conventional in vitro fertilization (IVF) in horses include variation in sperm and oocyte quality, which can be affected by mare age. Extended preincubation of stallion spermatozoa has resulted in successful IVF.

Impact of temporal tear meniscus height on the tear osmolarity measurements

open access: yesScientific Reports
Tear hyperosmolarity plays a crucial role in initiation of inflammatory response and damage to ocular surface epithelia. Accurate measurement of tear osmolarity is essential for dry eye. This prospective observational and experimental study was conducted

Lactate‐Responsive Glycogen Dynamics Are Associated With Bull Sperm Motility and Fertilization Under Glucose‐Limited Conditions

open access: yesAndrology, EarlyView.
ABSTRACT Background Mammalian sperm need to undergo hyperactivation, capacitation, and acrosome reaction to achieve fertilization competence. However, the female reproductive tract presents contrasting metabolic environments. The uterus is glucose‐rich, and the oviduct is lactate‐rich and glucose‐limited.

Tear osmolarity is sensitive to exercise-induced fluid loss but is not associated with common hydration measures in a field setting

open access: yes, 2017
This investigation (i) examined changes in tear osmolarity in response to fluid loss that occurs with exercise in a field setting, and (ii) compared tear osmolarity with common field and laboratory hydration measures.\ua0 Sixty-three participants [age 27.

Is retinal vein occlusion an underrecognized paraneoplastic sentinel of lymphoma? A systematic review and meta‐analysis of ocular–haematological interactions

open access: yesActa Ophthalmologica, EarlyView.
Abstract Topic This systematic review and meta‐analysis evaluated the association between retinal vein occlusion (RVO) and lymphoma across two complementary evidence components: a qualitative clinical synthesis of RVO occurring in patients with lymphoma and a quantitative synthesis of subsequent cancer outcomes in patients with RVO. For the qualitative

Low‐level light therapy for dry eye disease and meibomian gland dysfunction: A systematic review and meta‐analysis

open access: yesActa Ophthalmologica, EarlyView.
Abstract A healthy tear film is vital for ocular surface integrity and relies on the coordinated function of the lacrimal glands, meibomian glands and conjunctival goblet cells. Dysfunction in any of these elements can lead to dry eye disease (DED). This systematic review and meta‐analysis evaluated the efficacy of low‐level light therapy (LLLT) as a ...
