PURPOSE: This study evaluated the effect of storage in water and thermocycling on hardness and roughness of resin materials for temporary restorations. MATERIAL AND METHODS: Three acrylic resins (Dencor-De, Duralay-Du, and Vipi Cor-VC) were selected and one composite resin (Opallis-Op) was used as a parameter for comparison. The materials were prepared according to the manufacturers' instructions and were placed in stainless steel moulds (20 mm in diameter and 5 mm thick). Thirty samples of each resin were made and divided into three groups (n = 10) according to the moment of Vickers hardness

Objective To investigate the effect of abstention from breastfeeding, for an hour before and after each vaccination, on the immune responses of infants to two doses of rotavirus vaccine. Methods In Soweto, South Africa, mother–infant pairs who were uninfected with human immunodeficiency virus (HIV) were enrolled as they presented for the “6-week” immunizations of the infants. Each infant was randomly assigned to Group 1 – in which breastfeeding was deferred for at least 1 h before and after each dose of rotavirus vaccine – or Group 2 – in which unrestricted breastfeeding was encouraged.

In avian species, the central nervous system orchestrates feeding behavior through intricate interplay among diverse neurotransmitter pathways. Epidermal Growth Factor (EGF), a key peptide in cell growth and repair, has been implicated in appetite control in mammals, but its role in avian species remains unexplored. The present study was conducted to investigate the effect of central infusion of EGF on food consumption in neonatal broilers and to determine the possible involvement of dopaminergic and adrenergic systems. In a series of experiments, 5-day-old male broilers were subjected to intr

Abstract Background Kinins play an important role in regulation of pain and hyperalgesia after tissue injury and inflammation by activating two types of G-protein-coupled receptors, the kinin B 1 and B 2 receptors. It is generally accepted that the B 2 receptor is constitutively expressed, whereas the B 1 receptor is induced in response to inflammation. However, little is known about the regulatory effects of kinin receptors on the onset of acute inflammation and inflammatory pain in humans. The present study investigated the changes in gene expression of kinin receptors and the levels of thei

Abstract Cyberbullying and cybervictimization have become widespread phenomena on social media platforms, particularly in emotionally charged environments such as sports fandom. While prior research has emphasized the role of individual personality traits, the influence of social identification—specifically, fan identity—on these behaviors remains underexplored, especially within Chinese digital communities, such as Sina Weibo. Grounding the study in the Social Identity Model of Deindividuation Effects, we theorize that platform affordances, such as anonymity and group salience, amplify identi

Obstructive sleep apnoea (OSA) involves impaired upper airway muscle function and is linked to several pathologies including systemic hypertension, daytime somnolence and cognitive decline. Selenium is an essential micronutrient that exerts many of its effects through selenoproteins. Evidence indicates that either deficient or excessive dietary selenium intake can result in impaired muscle function, termed nutritional myopathy. To investigate the effects of selenium on an upper airway muscle, the sternohyoid, rats were fed on diets containing deficient, normal (0.5 ppm sodium selenite) or exce
