Correction of severe tooth rotation by using two different orthodontic ‎appliances: Report of two cases

Journal of Oral Health and Oral Epidemiology, 2015
BACKGROUND AND AIM: Severe rotation of tooth is one of the most common problems in orthodontics and considered as a developmental phenomenon. These rotations can cause cosmetic problems, gingival recession, and traumatic occlusion.

Feeding Practices and Welfare of Zoo‐Housed Giraffes (Giraffa camelopardalis) on a Global Scale

Zoo Biology, EarlyView.
We collected feeding and stereotypy information on 702 giraffes from 146 zoos from all over the world. Less appropriate diets were linked to more oral stereotypies. ABSTRACT Since giraffe feeding practices have only been reported for European and US facilities, this study aimed to achieve a comprehensive overview of the current giraffe feeding ...

A reappraisal of the Middle to Later Stone Age prehistory of Morocco Réévaluer la préhistoire du Maroc, du Middle Stone Age au Later Stone Age

Journal of the Royal Anthropological Institute, EarlyView.
Over the last 25 years, perceptions of the early prehistory of Northwest Africa have undergone radical changes due to new fieldwork projects and a corresponding growth in scientific interest in the region. Much of this work has been focused in Morocco, known for its extremely rich fossil and archaeological records in caves and rock shelters.

Blubber Thickening Driven by UCP1 Inactivation: Insights from a Cetacean‐Like Transgenic Mouse Model

Integrative Zoology, EarlyView.
UCP1 inactivation of cetaceans in mice drives BAT whitening and iWAT hyperplasia, promoting fat accumulation for aquatic adaptation. Abstract Cetaceans possess thick blubber, a specialized adipose tissue essential for thermal insulation, a streamlined body form, energy storage, and buoyancy. However, the mechanisms that underpin this adaptation are not

Decoding Dual Regulatory Layers: Integrating Differential Expression and Alternative Splicing Dynamics in the Evolution of Laryngeal Echolocation Across Chiropteran Lineages

Integrative Zoology, EarlyView.
We integrated short‐read and long‐read RNA‐seq data from cochlear tissues of echolocating and non‐echolocating bats to disentangle transcriptional and post‐transcriptional regulation. Echolocating bats showed neural‐function enrichment among differentially expressed genes, while alternatively spliced genes were linked to epigenetic regulation. Overlaps

Female‐Biased Sexual Size Dimorphism and Its Potential Causes in Hairy‐Winged Bats

Integrative Zoology, EarlyView.
Based on the integration of molecular genetics, traditional and geometric morphology, and acoustic characteristics of hairy‐winged bats (a species that was historically misclassified into two species due to extreme craniodental divergence between the sexes) in multiple regions of China, we quantified the sexual size dimorphism (SSD) between males and ...

Examining the role of freebase nicotine in the harm reduction potential of oral nicotine pouches versus moist snuff: A randomized crossover trial

Addiction, EarlyView.
Abstract Background and aims Oral nicotine pouches (ONPs) contain varying proportions of freebase nicotine (FBN), with higher FBN expected to increase nicotine delivery across the oral mucosa. Because ONPs contain fewer toxicants than moist snuff and may serve as a reduced harm alternative for smokeless tobacco, we compared how the FBN in ONPs affects ...
