Periodontal considerations during orthodontic intrusion and extrusion in healthy and reduced periodontium

Periodontology 2000, EarlyView.
Abstract In patients with advanced periodontal disease, pathological tooth migration may occur, which may require subsequent orthodontic treatment for both aesthetic and functional purposes. When planning orthodontic treatment mechanics, intrusive or extrusive forces are frequently indicated.

Breathing irregularities and postnatal hypoxaemia in an experimental model of essential hypertension

The Journal of Physiology, EarlyView.
Abstract figure legend Neonatal spontaneously hypertensive rats (SHRs) exhibit inherent respiratory dysfunction in early life, including oscillatory breathing patterns and apnoeic events that cause oxygen desaturation and brain hypoxia, in addition to an impaired hypoxic ventilatory response.

Diet and coexistence of Rattus rattus rattus (Linnaeus), Rattus exulans (Peale) and Rattus norvegicus (Berkenhout) on Stewart Island, New Zealand : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Zoology [PDF]

, 1988
Coexistence and diet of Rattus rattus rattus, Rattus exulans and, Rattus norvegicus on Stewart Island was investigated by snap-trapping and stomach analysis. The trapping period was from June 1982 to December 1986.

Predation by Rattus norvegicus on a native small mammal in an Araucaria araucana forest of Neuquén, Argentina La depredación en pequeños mamíferos nativos por Rattus norvegicus en un bosque de Araucaria araucana en Neuquén, Argentina

Revista Chilena de Historia Natural, 2012
Few previous studies document Rattus predation as a mechanism of impact on native small mammals. In a mixed Araucaria araucana (Molina) Koch -Nothofagus forest in Parque Nacional Lanín in southwestern Neuquén Province, Argentina, we discovered the ...

The ageing holobiont: crosstalk between telomere dynamics, oxidative stress and the gut microbiome

Biological Reviews, Volume 101, Issue 4, Page 1877-1903, August 2026.
ABSTRACT The gut tissue is at the frontline of early onset of ageing. It exhibits high cell turnover rates and rapid telomere shortening, which can have systemic effects on the developing or senescing organism. We conducted a literature review of studies on the crosstalk between telomere length dynamics, telomerase activity, oxidative stress, and gut ...

Vagus Nerve Stimulation Paired With Tones Alters the Auditory Cortex Proteome in a Rat Model of Rett Syndrome

Developmental Neurobiology, Volume 86, Issue 3, July 2026.
ABSTRACT Rett syndrome is a neurodevelopmental disorder caused by an X‐linked mutation of the MeCP2 gene. Individuals with Rett syndrome, as well as rodent models of this disorder, demonstrate abnormal cortical responses to sound, which impair auditory discrimination ability.

Mitigation of Hepatic and Pancreatic Injury by Spondias tuberosa Extract Through Oxidative Enzyme Modulation and TGF‐β Downregulation

Food Science &Nutrition, Volume 14, Issue 7, July 2026.
Treatment with Spondias tuberosa extract ameliorated pancreatic and hepatic morphological damage in STZ‐induced diabetic rats, potentially by reducing oxidative stress and modulating profibrotic signaling mediated by TGF‐β. ABSTRACT Diabetes mellitus (DM) is a chronic metabolic disorder marked by hyperglycemia due to impaired insulin secretion and/or ...

Regulation of Endoplasmic Reticulum Stress Suppresses Early Pro‐Tumorigenic Events During N‐Nitrosodiethylamine‐Induced Hepatocarcinogenesis

Journal of Biochemical and Molecular Toxicology, Volume 40, Issue 7, July 2026.
Schematic illustration of the effect of BIX in attenuating the initiation stage of hepatocarcinogenesis. BIX pre‐treatment mitigated N‐nitrosodiethylamine‐induced ER stress, DNA damage, and downstream pro‐tumorigenic events during the initiation phase. It preserved DNA repair capacity, reduced inflammation and cellular proliferation, thereby inhibiting
