BACKGROUND: Drug-induced gingival overgrowth (DIGO) is attributed mainly to the prolonged use of calcium channel blocking agents, anticonvulsants, and anti-calcineurin inhibitors . The management of DIGO depends on the severity of the disease and includes surgical intervention and plaque control. Compared to conventional surgical treatment, the recent literature data have shown that gingivectomy using a high-power laser (HPL) is a short and easy procedure, which results in minimal postoperative discomfort and greater patient accep- tance...

Atypical antipsychotic drugs have been associated with the development of obesity and diabetes. In particular, olanzapine can induce peripheral insulin resistance and compensatory hyperinsulinemia independent of weight gain or psychiatric disease. To determine if this compensatory increase in insulin is mediated by parasympathetic muscarinic stimulation, we randomized fifteen healthy subjects 2:1 to receive double-blind olanzapine or placebo for 9 days under diet and activity controlled inpatient conditions...

An intact blood-brain barrier (BBB) limits entry of pro-inflammatory and neurotoxic blood-derived factors into the brain parenchyma. The BBB is damaged in Alzheimer's disease (AD), which contributes significantly to the progression of AD pathologies and cognitive decline. However, the mechanisms underlying BBB breakdown in AD remain elusive and no interventions are available for treatment or prevention. We and others recently established that inhibition of the mammalian/mechanistic target of rapamycin (mTOR) pathway with rapamycin yields significant neuroprotective effects, improving cerebrovascular and cognitive function in mouse models of AD...

The rapid expansion of the elderly population has led to the recent epidemic of age-related diseases, including increased incidence and mortality of chronic and acute lung diseases. Numerous studies have implicated aging and oxidative stress in the pathogenesis of various pulmonary diseases; however, despite recent advances in these fields, the specific contributions of aging and oxidative stress remain elusive. This review will discuss the consequences of aging on lung morphology and physiology, and how redox imbalance with aging contributes to lung disease susceptibility...

The metabolism of nutrient substrates including glucose, glutamine and fatty acids provides acetyl-CoA for the tricarboxylic acid cycle to generate energy, and metabolites for the biosynthesis of biomolecules including nucleotides, proteins, and lipids. It has been shown that metabolism of glucose, fatty acid, and glutamine plays important roles in modulating cellular proliferation, differentiation, apoptosis, autophagy, senescence, and inflammatory responses. All these cellular processes contribute to the pathogenesis of chronic lung diseases, including bronchopulmonary dysplasia, chronic obstructive pulmonary disease, and pulmonary fibrosis...

Qing Lu, Eric Gottlieb, Sharon Rounds
Cigarette smoking is the leading cause of preventable disease and death in the US. Cardiovascular co-morbidities associated with both active and secondhand cigarette smoking indicate the vascular toxicity of smoke exposure. Growing evidence supports the injurious effect of cigarette smoke on pulmonary endothelial cells and the roles of endothelial cell injury in development of Acute Respiratory Distress Syndrome (ARDS), emphysema, and pulmonary hypertension. This review summarizes results from studies of humans, preclinical animal models, and cultured endothelial cells that document toxicities of cigarette smoke exposure on pulmonary endothelial cell functions, including barrier dysfunction, endothelial activation and inflammation, apoptosis, and vasoactive mediator production...

The intestinal epithelium constitutes an innate barrier which, upon injury, undergoes self-repair processes known as restitution. Although, bile acids are known as important regulators of epithelial function in health and disease, their effects on wound healing processes are not yet clear. Here we set out to investigate the effects of the colonic bile acids, deoxycholic acid (DCA) and ursodeoxycholic acid (UDCA) on epithelial restitution. Wound healing in T84 cell monolayers grown on transparent, permeable, supports was assessed over 48 hrs {plus minus} bile acids...

BACKGROUND: There is minimal evidence on the extent to which the occurrence of a severe acute exacerbation of COPD that results in hospitalization affects the subsequent disease course. Previous studies on this topic did not generate causally-interpretable estimates. Our aim was to use corrected methodology to update previously reported estimates of the associations between previous and future exacerbations in these patients. METHODS: Using administrative health data in British Columbia, Canada (1997-2012), we constructed a cohort of patients with at least one severe exacerbation, defined as an episode of inpatient care with the main diagnosis of COPD based on international classification of diseases (ICD) codes...

Recent advances in statistical methods enable the study of correlation among outcomes through joint modeling, thereby addressing spillover effects. By joint modeling, we refer to simultaneously analyzing two or more different response variables emanating from the same individual. Using the 2011 Bangladesh Demographic and Health Survey, we jointly address spillover effects between contraceptive use (CUC) and knowledge of HIV and other sexually transmitted diseases. Jointly modeling these two outcomes is appropriate because certain types of contraceptive use contribute to the prevention of HIV and STDs and the knowledge and awareness of HIV and STDs typically lead to protection during sexual intercourse...

BACKGROUND: Maternal group B streptococcal (GBS) vaccines under development hold promise to prevent GBS disease in young infants. Sub-Saharan Africa has the highest estimated disease burden, although data on incidence and circulating strains are limited. We described invasive bacterial disease (IBD) trends among infants <90 days in rural Mozambique during 2001-2015, with a focus on GBS epidemiology and strain characteristics. METHODS: Community-level birth and mortality data were obtained from Manhiça's demographic surveillance system...

BACKGROUND AND PURPOSE: The Centers for Disease Control and Prevention estimated that there were 29 million falls and 7 million injuries in 2014 in the United States. Falls, decreased balance, and mobility disability are common in older adults and often result in loss of independence. Finding interventions to address these issues is important, as this age group is growing exponentially. Prior studies indicate balance and mobility can be improved by the balance-based torso-weighting (BBTW) assessment implemented through wear of a balance orthotic (BO)...

PURPOSE OF REVIEW: Resting-state fMRI assessment of instrinsic functional brain connectivity (rs-fcMRI) in autism spectrum disorders (ASD) allows assessment of participants with a wide range of functioning levels, and collection of multisite databases that facilitate large-scale analysis. These heterogeneous multisite data present both promise and methodological challenge. Herein, we provide an overview of recent (1 October 2016-1 November 2017) empirical research on ASD rs-fcMRI, focusing on work that helps clarify how best to leverage the power of these data...

The complex neuronal networks of the spinal cord coordinate a wide variety of motor functions, including walking, running and voluntary and involuntary movements. This is accomplished by different groups of neurons, called center pattern generators, which control left-right alternation and flexor-extensor patterns. These spinal circuits, located in the ventral horns, are formed by several neuronal types, and the specific function of most of them has been identified by means of studies in vivo and in the isolated spinal cord of mice harboring genetically induced ablation of specific neuronal populations...

Increased life expectancy, due to the rise in life quality and the decline in mortality rates, is leading to a society in which the population aged 60 and over is growing more rapidly than the entire population. Although various models and model organisms have been employed to investigate the mechanism of aging, induced pluripotent stem cells (iPSCs) are useful candidates to study human aging and age-related human diseases. This work discusses how iPSCs can be used as an alternative to the model organisms such as yeast, Caenorhabditis elegans, Drosophila melanogaster, or the mouse...

The dried fruit of Sophora japonica L. is a traditional Chinese herb tea rich in sophoricoside that is an isoflavone glycoside. The aim of current study was to investigate the hepatic protective effect of sophoricoside in high fructose (HF) diet fed mice. Healthy male mice were fed 30% fructose water and treated 80 and 160 mg/kg·bw sophoricoside continuously for 8 wk. Our data showed that administration of sophoricoside at 80 and 160 mg/kg·bw observably decreased the body weight and liver weight in HF-fed mice...

BACKGROUND: Sinusoidal obstruction syndrome (SOS), also called hepatic veno-occlusive disease (VOD), is a potentially life-threatening complication of hematopoietic stem cell transplantation (HSCT) that affects about 1 in 7 patients undergoing this procedure. SOS/VOD is caused by the conditioning regimens administered prior to HSCT; in some cases, SOS/VOD results from chemotherapy alone. SOS/VOD usually develops within three weeks following HSCT; however, it can have later onset.

Abciximab is a glycoprotein IIb/IIIa receptor antagonist that functions to prevent platelet aggregation, thus reducing thrombus initiation and propagation. It has been widely used during percutaneous endovascular interventions, such as aneurysm coil embolization, angioplasty, atherectomy, and stent placement, as both a preventative and a salvage therapy. The use of abciximab in cardiac and neurosurgical procedures has been associated with a reduced incidence of ischemic complications and a decreased need for repeated intervention...
