Strategies for optimization of hypoglycemia rat models

open access: yesAnimal Models and Experimental Medicine, EarlyView.
This review focuses on rat models for studying the short‐term and long‐term effects of mild and severe hypoglycemia. We explored the physiological mechanisms to understand the consequences of hypoglycemia in rat experimental models. This study sheds light on uncovering the therapeutic potential for hypoglycemic patients and its efficacy in mitigating ...

Disparity of turbinal bones in placental mammals

open access: yesThe Anatomical Record, EarlyView.
Abstract Turbinals are key bony elements of the mammalian nasal cavity, involved in heat and moisture conservation as well as olfaction. While turbinals are well known in some groups, their diversity is poorly understood at the scale of placental mammals, which span 21 orders.

Latitudinal Variation in Seasonal Activity and Mortality in Ratsnakes (Elaphe obsoleta)

open access: yes, 2010
The ecology of ectotherms should be particularly affected by latitude because so much of their biology is temperature dependent. Current latitudinal patterns should also be informative about how ectotherms will have to modify their behavior in response ...

Inside the head of Crotalus durissus LINNAEUS, 1758 (Serpentes, Viperidae, Crotalinae): Macroscopic description of the brain with ontogenetic insights

open access: yesThe Anatomical Record, EarlyView.
Abstract Neuroanatomy studies in vertebrates have garnered significant attention in recent years, particularly driven by advancements in computerized tomography imaging techniques. Nonetheless, these advancements remain largely constrained to specific vertebrate groups, notably mammals, birds, and fish, leaving studies in reptiles at an incipient stage.

Temperature exposure and possible thermoregulation strategies in the Titicaca water frog Telmatobius culeus, a fully aquatic frog of the High Andes

open access: yesEndangered Species Research, 2018
Temperature has an important effect on amphibians, influencing virtually all physiological systems. Thermoregulation is used to manage unfavourable thermal conditions, but has been poorly studied in aquatic amphibians, and no information is available for

Inside a duck‐billed dinosaur: Vertebral bone microstructure of Huallasaurus (Hadrosauridae), Upper Cretaceous of Patagonia

open access: yesThe Anatomical Record, EarlyView.
Abstract Dinosaurs evolved a unique respiratory system with air sacs that contributed to their evolutionary success. Postcranial skeletal pneumaticity (PSP) has been used to infer the presence of air sac systems in some fossil archosaurs. While unambiguous evidence of PSP is well documented in pterosaurs and post‐Carnian saurischians, it remains absent

Temperature elevation in the human brain and skin with thermoregulation during exposure to RF energy

open access: yesBioMedical Engineering OnLine, 2018
Two international guidelines/standards for human protection from electromagnetic fields define the specific absorption rate (SAR) averaged over 10 g of tissue as a metric for protection against localized radio frequency field exposure due to portable ...

Effects of age, density, and seasonality on molt pattern in the mammal genus (Peromyscus) [PDF]

open access: yes, 2015
Molting, or replacement of pelage (hair) in mammals, occurs during ontogeny as individuals transition from juveniles to adults. Environmental factors can cause variation in molt in many species for thermoregulatory and camouflage purposes.
