Is There Any Association Between Periodontitis and Prostatic Alterations? A Systematic Review.

Background: The prostate plays a crucial role in male reproduction but is susceptible to diseases such as prostate cancer. Periodontitis, as an inflammatory disease, has the potential to modulate systemic conditions. This systematic review aimed to evaluate the association between periodontitis and prostatic alterations.

Dental enamel following maternal exposure to different fluoride concentrations: Physicochemical and functional approaches in rats offspring.

Excessive fluoride (F) exposure is associated with adverse effects at different life stages and can affect various biological systems, including the mineralized tissues of the oral cavity. However, there is limited evidence that early F exposure during pregnancy and lactation impairs the development of offspring dental enamel. From a translational perspective, this study aimed to investigate the effects of F at different concentrations on the ultrastructural, physicochemical, and functional properties of dental enamel in the offspring of rats exposed during the prenatal and lactation periods.

This study aimed to explore how the long-term use of midazolam (MDZ) influences the biochemistry and structural alterations in the salivary glands of adult rats, along with the function of their saliva. Twenty male Wistar rats were allocated in two groups (n = 10) and received daily intragastric administration of 0.1mg/kg MDZ solubilized in distilled water or only distilled water (control) for 30 days.

Impact of fluoride exposure at different concentrations on preosteoblastic cells: Molecular, biochemical, and morphological insights.

Fluoride can harm various tissues depending on its concentration and exposure duration. While its effects on mineralized tissues like bones and teeth are known, few studies have explored its impact on preosteoblastic cells. This study examined the effects of fluoride on differentiating osteoblastic cells.

Evaluation of alveolar bone preservation and oxidative stress reduction with açai in Wistar rats with induced apical periodontitis.

Aim: This study aimed to investigate the effects of açai on bone and systemic damage caused by apical periodontitis (AP) in an animal model.

Methodology: In this experimental study, 32 male Wistar rats were randomly allocated into six groups-Control 14 days (n = 4), Control 28 days (n = 4), AP 14 days (n = 4), AP 28 days (n = 4), AP plus açai treatment for 14 days (n = 8) and AP plus açai treatment for 28 days (n = 8). Apical periodontitis was induced under general anaesthesia by exposing the pulp of the first molars to the oral environment.

Potential effects of induced focal ischemia in the motor cortex of rats undergoing experimental periodontitis.

Stroke is a severe medical condition resulting from an interruption in the blood supply to the brain, ultimately compromising tissue homeostasis. Currently, stroke stands as the second leading cause of death worldwide and the third leading cause when considering both mortality and disability together. Periodontitis is characterized by persistent inflammation in hard and soft tissues which support the teeth, primarily caused by bacterial biofilms, and is one of the most common causes of tooth loss in adults and can contribute to a systemic inflammatory burden.

Lead Toxicity and Maternal Exposure: Characterisation of Alveolar Bone Changes on Offspring Rats.

Lead poisoning is a global public health concern. Maternal exposure during intrauterine and lactational periods can present a higher susceptibility of harm to the offspring. Thus, pregnant female Wistar rats (Rattus norvegicus) were randomly divided in two experimental groups: control group and Lead group.

Minocycline reduces alveolar bone loss and bone damage in Wistar rats with experimental periodontitis.

This study aimed to investigate the impact of minocycline on the alveolar bone in experimental periodontitis in rats. Thirty Wistar rats were randomly assigned to three groups: control without periodontitis; experimental periodontitis induced by ligature; experimental periodontitis + intraperitoneal administration minocycline for seven days. Ligatures remained in place in both periodontitis groups for 14 days.

Physical training minimizes immunological dysfunction, oxidative stress and tissue destruction on experimental periodontitis in rats.

The objective of this study is to investigate the effects of a moderate intensity physical training protocol, on alveolar bone morphology of rats submitted to ligature-induced periodontitis. Twenty-eight male Wistar rats were divided into four groups, considering the presence/absence of periodontitis and presence/absence of training. The training protocol was performed on a treadmill, 30 min/day, 5 days a week, for 4 weeks.

Açai ( Mart.) supplementation promotes histological and ultrastructural changes in rats' alveolar bone.

The açai juice contains high concentrations of phenolic compounds, including cyanidin-3-glucoside and others flavonoids. The aim of this study was to evaluate the impact of açai supplementation on healthy mandibular alveolar bone in male albino rats of the Wistar strain. 24 rats were divided into 3 groups, in which one group received a daily dose of saline solution and the other two groups were treated with daily doses of clarified açai juice for 14 or 28 days.

Physical training mitigates alveolar bone and blood enzymatic antioxidants defense impairment induced by binge ethanol consumption in rats.

We aimed to investigate the effectiveness of physical training as a protective strategy to mitigate alveolar bone damage and blood antioxidant defense caused by ethanol (EtOH) consumption in a binge-drinking pattern. Male Wistar rats aged approximately 90 days were divided into four groups: control, training, EtOH, and training + EtOH. The physical training protocol was conducted on a treadmill for four consecutive weeks, while the animals in the EtOH group were administered EtOH via orogastric gavage for three consecutive days each week, following the binge drink pattern.

Ethanol binge drinking exposure during adolescence displays long-lasting motor dysfunction related to cerebellar neurostructural damage even after long-term withdrawal in female Wistar rats.

Ethanol is one of the psychoactive substances most used by young individuals, usually in an intermittent and episodic manner, also called binge drinking. In the adolescent period, brain structures undergo neuromaturation, which increases the vulnerability to psychotropic substances. Our previous studies have revealed that ethanol binge drinking during adolescence elicits neurobehavioral alterations associated with brain damage.

Cellular and Molecular Pathophysiology of Traumatic Brain Injury: What Have We Learned So Far?

Traumatic brain injury (TBI) is one of the leading causes of long-lasting morbidity and mortality worldwide, being a devastating condition related to the impairment of the nervous system after an external traumatic event resulting in transitory or permanent functional disability, with a significant burden to the healthcare system. Harmful events underlying TBI can be classified into two sequential stages, primary and secondary, which are both associated with breakdown of the tissue homeostasis due to impairment of the blood-brain barrier, osmotic imbalance, inflammatory processes, oxidative stress, excitotoxicity, and apoptotic cell death, ultimately resulting in a loss of tissue functionality. The present study provides an updated review concerning the roles of brain edema, inflammation, excitotoxicity, and oxidative stress on brain changes resulting from a TBI.

Neurotoxicology of alcohol: a bibliometric and science mapping analysis.

Alcohol consumption is common in many societies and has increased considerably, resulting in many socioeconomic and public health problems. In this sense, studies have been carried out in order to understand the mechanisms involved in alcohol consumption and related harmful effects. This study aimed to identify and map the knowledge and to perform bibliometric analysis of the neurotoxicology of alcohol based on the 100 most cited articles.

Prolonged exposure to high fluoride levels during adolescence to adulthood elicits molecular, morphological, and functional impairments in the hippocampus.

Fluoride is added to water due to its anticariogenic activity. However, due to its natural presence in soils and reservoirs at high levels, it could be a potential environmental toxicant. This study investigated whether prolonged exposure to fluoride from adolescence to adulthood-at concentrations commonly found in artificially fluoridated water and in fluorosis endemic areas-is associated with memory and learning impairments in mice, and assessed the molecular and morphological aspects involved.

Astrocytosis, Inflammation, Axonal Damage and Myelin Impairment in the Internal Capsule following Striatal Ischemic Injury.

Secondary degeneration is defined as a set of destructive events that damage cells and structures that were initially spared or only peripherally affected by the primary insult, constituting a key factor for functional impairment after traumatic brain injury or stroke. In the present study, we evaluated the patterns of astrocytosis, inflammatory response, axonal damage and oligodendrocytes/myelin impairment in the internal capsule following a focal injection of endothelin-1 (ET-1) into the dorsal striatum. Animals were perfused at 1, 3 and 7 post-lesion days (PLD), and tissue was processed to immunohistochemistry for neutrophils (MBS1), macrophages/microglia (ED1), astrocytes (GFAP), axonal lesion (βAPP), oligodendrocytes (Tau) and myelin (MBP).

Exposure to tolerable concentrations of aluminum triggers systemic and local oxidative stress and global proteomic modulation in the spinal cord of rats.

The tolerable aluminum (Al) intake levels for humans are constantly under review by regulatory agencies due to novel pre-clinical evidence on the neurotoxicity of prolonged Al exposure; however, little is known about the effects of Al on the spinal cord. This study aimed to investigate potential adverse effects on both spinal cord and systemic biochemical balance after prolonged exposure to a low dose of Al. Twenty adult rats were distributed in the control (distilled water) and exposed group (8.
