Interactions between Insomnia, Sleep Disordered Breathing and Cardiometabolic Risk in Patients Complaining of Pain in the Orofacial Region.

The existence of intersected pathways between the mechanisms of insomnia, sleep-disordered breathing and persistent/chronic pain has been documented. Such concurrence will eventually contribute to a higher burden of cardiometabolic diseases, a main cause of death worldwide. The aim of this study was to evaluate the interactions between insomnia, sleep-disordered breathing, cardiometabolic risk, and psychosocial stress in patients seeking care at an orofacial pain clinic.

A Tale of Two Diagnoses; Gout Vs Chronic Osteomyelitis. A Case Report.

Gout can potentially be diagnosed clinically and treated, if classical symptoms are present. In some cases, gout and osteomyelitis can have similar presenting signs and symptoms and it may be difficult to differentiate just on clinical presentation, routine laboratory workup and imaging like radiography or ultrasound. Arthrocentesis can be crucial in such scenarios to differentiate the two entities as missed opportunity to treat infectious etiology can have detrimental outcomes.

DISCOVERY AND VALIDATION OF GENES DRIVING DRUG-INTAKE AND RELATED BEHAVIORAL TRAITS IN MICE.

Substance use disorders (SUDs) are heritable disorders characterized by compulsive drug use, but the biological mechanisms driving addiction remain largely unknown. Genetic correlations reveal that predisposing drug-naïve phenotypes, including anxiety, depression, novelty preference, and sensation seeking, are predictive of drug-use phenotypes, implicating shared genetic mechanisms. Because of this relationship, high-throughput behavioral screening of predictive phenotypes in knockout (KO) mice allows efficient discovery of genes likely to be involved in drug use.

Modified Periodic Acid-Schiff (PAS) Is an Alternative to Safranin O for Discriminating Bone-Cartilage Interfaces.

Cartilage histomorphometry is often performed on decalcified, paraffin-embedded bone sections, which provide versatility in staining applications from basic morphology to immunohistochemistry. Safranin O is a cationic dye that binds to proteoglycans in cartilage and is routinely used to assess growth plate dynamics and/or fracture repair at bone-cartilage interfaces. When used with a counterstain such as fast green, safranin O can offer exquisite differentiation of cartilage from surrounding bone.

Thymidine Phosphorylase Deficiency or Inhibition Preserves Cardiac Function in Mice With Acute Myocardial Infarction.

Background Ischemic cardiovascular disease is the leading cause of death worldwide. Current pharmacologic therapy has multiple limitations, and patients remain symptomatic despite maximal medical therapies. Deficiency or inhibition of thymidine phosphorylase (TYMP) in mice reduces thrombosis, suggesting that TYMP could be a novel therapeutic target for patients with acute myocardial infarction (AMI).

Influence of landscape condition on relative abundance and body condition of two generalist freshwater turtle species.

Anthropogenic land use changes have broad impacts on biological diversity, often resulting in shifts in community composition. While many studies have documented negative impacts on occurrence and abundance of species, less attention has been given to native species that potentially benefit from anthropogenic land use changes. For many species reaching high densities in human-dominated landscapes, it is unclear whether these environments represent higher quality habitat than more natural environments.

Epithelial and Endothelial Adhesion of Immune Cells Is Enhanced by Cardiotonic Steroid Signaling Through Na/K-ATPase-α-1.

Background Recent studies have highlighted a critical role for a group of natriuretic hormones, cardiotonic steroid (CTS), in mediating renal inflammation and fibrosis associated with volume expanded settings, such as chronic kidney disease. Immune cell adhesion is a critical step in the inflammatory response; however, little is currently understood about the potential regulatory role of CTS signaling in this setting. Herein, we tested the hypothesis that CTS signaling through Na/K-ATPase α-1 (NKA α-1) enhances immune cell recruitment and adhesion to renal epithelium that ultimately advance renal inflammation.

Early Rapid Decline in Kidney Function in Medically Managed Patients With Atherosclerotic Renal Artery Stenosis.

Background Early rapid declines of kidney function may occur in patients with atherosclerotic renal artery stenosis with institution of medical therapy. The causes and consequences are not well understood. Methods and Results Patients enrolled in the medical therapy-only arm of the CORAL (Cardiovascular Outcomes With Renal Artery Lesions) study were assessed for a rapid decline (RD) in estimated glomerular filtration rate (eGFR), defined as a ≥30% decrease from baseline to either 3 months, 6 months, or both.

Verrucous carcinoma arising in a long standing Buschke-Löwenstein tumor.

Giant condyloma acuminatum is a rare variant of genital warts also known as Buschke-Löwenstein tumor. It is characterized by a slow progression of exophytic, ulcerative, and cauliflower-shaped tumor with benign histological features. Verrucous carcinoma however is a rare variant of well-differentiated squamous cell carcinoma with limited metastatic potential.

Semi-supervised determination of pseudocryptic morphotypes using observer-free characterizations of anatomical alignment and shape.

Accurate, quantitative characterization of complex shapes is recognized as a key methodological challenge in biology. Recent development of automated three-dimensional geometric morphometric protocols (auto3dgm) provides a promising set of tools to help address this challenge. While auto3dgm has been shown to be useful in characterizing variation across clades of morphologically very distinct mammals, it has not been adequately tested in more problematic cases where pseudolandmark placement error potentially confounds interpretation of true shape variation.

Carbonylation Modification Regulates Na/K-ATPase Signaling and Salt Sensitivity: A Review and a Hypothesis.

Na/K-ATPase signaling has been implicated in different physiological and pathophysiological conditions. Accumulating evidence indicates that oxidative stress not only regulates the Na/K-ATPase enzymatic activity, but also regulates its signaling and other functions. While cardiotonic steroids (CTS)-induced increase in reactive oxygen species (ROS) generation is an intermediate step in CTS-mediated Na/K-ATPase signaling, increase in ROS alone also stimulates Na/K-ATPase signaling.

Epigenetics as an answer to Darwin's "special difficulty," Part 2: natural selection of metastable epialleles in honeybee castes.

In a recent perspective in this journal, Herb (2014) discussed how epigenetics is a possible mechanism to circumvent Charles Darwin's "special difficulty" in using natural selection to explain the existence of the sterile-fertile dimorphism in eusocial insects. Darwin's classic book "On the Origin of Species by Means of Natural Selection" explains how natural selection of the fittest individuals in a population can allow a species to adapt to a novel or changing environment. However, in bees and other eusocial insects, such as ants and termites, there exist two or more castes of genetically similar females, from fertile queens to multiple sub-castes of sterile workers, with vastly different phenotypes, lifespans, and behaviors.

Identification and characterization of CHCHD1, AURKAIP1, and CRIF1 as new members of the mammalian mitochondrial ribosome.

Defects in mitochondrial ribosomal proteins (MRPs) cause various diseases in humans. Because of the essential role of MRPs in synthesizing the essential subunits of oxidative phosphorylation (OXPHOS) complexes, identifying all of the protein components involved in the mitochondrial translational machinery is critical. Initially, we identified 79 MRPs; however, identifying MRPs with no clear homologs in bacteria and yeast mitochondria was challenging, due to limited availability of expressed sequence tags (ESTs) in the databases available at that time.

We are presenting the clinical features, diagnostic work up and treatment of acromegaly caused by Growth hormone releasing hormone (GHRH) secreting neuroendocrine tumor (NECT) in a case of multiple endocrine neoplasia type 1 (MEN-1). A 36 year old man, known case of MEN-1 presented with acromegalic features. He has high IGF-1, GH and very high GHRH levels with a pancreatic head tumor and pituitary mass.

Acetaminophen: beyond pain and Fever-relieving.

Acetaminophen, also known as APAP or paracetamol, is one of the most widely used analgesics (pain reliever) and antipyretics (fever reducer). According to the U.S.

Impact of obesity on early erectile function recovery after robotic radical prostatectomy.

Background And Objective: Studies are limited regarding the impact of obesity on early erectile functional outcomes after robotic radical prostatectomy. Our goal was to determine this impact using patient-reported validated questionnaires.

Methods: International Index of Erectile Function (IIEF-6) scores were prospectively collected with institutional review board approval, for patients who underwent robotic radical prostatectomy with bilateral nerve sparing from February 2007 to October 2009.

Larval fly activity on sunlit versus shaded raccoon carrion in southwestern West Virginia with special reference to the black blowfly (Diptera: Calliphoridae).

Larvae of Phormia regina (Meigen), Phaenicia sp., and Sarcophaga sp. were identified from raccoon carcasses placed in sunlit and shaded areas at a southwestern West Virginia site in May of 2000.

Ornithine decarboxylase (ODC) levels in children with reflux esophagitis.

Reflux esophagitis is a common disease in infants and can be diagnosed largely by esophageal biopsy. In adults, chronic esophagitis may lead to Barrett's esophagus, a premalignant condition for esophageal cancer development. Ornithine decarboxylase (ODC) is used as an early marker for colon cancer development.
