Unravelling the skin of the nurse shark: A morphological description of the placoid scales of Ginglymostoma cirratum

Journal of Fish Biology, EarlyView.
Abstract Ginglymostoma cirratum, commonly known as the nurse shark, is a nocturnally active benthic shark, often found in western and eastern Atlantic waters. Although this shark has been well explored in many biological aspects, few studies have thoroughly examined the morphology of its dermal denticles (or placoid scales).

The multidimensional regulation roles and mechanisms of calcium in fruit quality

Journal of Integrative Plant Biology, EarlyView.
This review explores how calcium signaling molecule integrates plant hormones, environmental cues, and developmental signals to influence external fruit traits, internal nutritional properties, and physiological disorders. ABSTRACT Calcium (Ca2+), a dual‐functional mineral that serves both as an essential structural factor and a signaling molecule ...

The Prevalence of Pulp Stones in Bangladeshi Adults

Journal of Chittagong Medical College Teachers' Association, 2016
Pulp Stones (PS) are discrete calcified masses found in the dental pulp. The purposes of this study were to calculate the prevalence of pulp stones in Bangladeshi adult’s undergone endodontic treatment and to report any observed associations between occurrence of pulp stones and sex, tooth type, dental arch, side and dental status. From 131 Bangladeshi

The Long Arc of Forest Land Dispossession and Degradation—Firm and State Actions on Sámi Lands in the Wood‐Based Commodity Frontier in Northern Sweden, 1673–1955

Journal of Agrarian Change, EarlyView.
ABSTRACT This article presents a new way of obtaining deep explanations of environmental problems. We expose the production strategies, corporate strategies and state actions that have been taken by firms and state agencies to facilitate the geographical expansion of the wood‐based commodity frontier at the expense of reindeer pastoralists among the ...

The Impact of Autonomous Truck Technology on US Interstate Trade

Journal of Regional Science, EarlyView.
ABSTRACT Recent advances in autonomous and semi‐autonomous vehicle technologies promise substantial cost savings for goods shipped by truck. In this study, we quantify the impacts of these transport cost reductions on the US interstate trade using a structural gravity model of domestic trade. Based on projected cost savings from the widespread adoption

Effect of Two Therapeutic Renal Diets on Hormonal and Regulatory Pathways Affecting Calcium Homeostasis in Cats With Early‐Stage Chronic Kidney Disease

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Chronic kidney disease (CKD) is a known risk factor for hypercalcemia in cats. Phosphate‐restricted diets have also been implicated in causing hypercalcemia, in part because phosphate restriction increases the Ca:P ratio. The primary objective of this study was to evaluate the impact of two different therapeutic renal foods on ionized (iCa ...

Autogenous Demineralized Dentin Graft–Based Strategies With or Without I‐PRF and Metronidazole for Ridge Preservation in Infected Sockets: A Randomized Clinical Trial

Journal of Periodontal Research, EarlyView.
This randomized controlled trial evaluated the efficacy of demineralized dentin graft (DDG) combined with injectable platelet‐rich fibrin (I‐PRF) and metronidazole (MTZ) versus DDG with or without I‐PRF in alveolar ridge preservation (ARP) of infected extraction sockets.

Dental pulp stones and their correlation with metabolic diseases

Journal of Oral and Maxillofacial Pathology
Abstract Background: Dental pulp calcifications or pulp stones are calcified structures found in dental pulp, mostly around or enclosing a blood vessel. The formation of these calcifications begins with concentric layers of calcified tissue within which remnants of necrotic and calcified cells may be present.

The Effects of Rapid Periodontal Distraction on Tooth Vitality and Bone Quality/Quantity: A Split‐Mouth Experimental Design

Orthodontics &Craniofacial Research, EarlyView.
ABSTRACT Objectives Periodontal distraction (PD) osteogenesis is a minimally invasive technique capable of rapidly moving uniradicular teeth, thereby shortening orthodontic treatment time. This study aimed to determine whether: (1) PD‐induced tooth movement affects tooth vitality and (2) the regenerated bone meets restorative standards for implant ...
