OBJECTIVES: Keratocystic odontogenic tumor (KCOT) demonstrates variable growth mechanisms and biologic behavior, partly due to origin and histology. We looked for the most contributing factors in predicting outcome of treatment. SUBJECTS AND METHODS: We retrospectively reviewed 118 medical files of patients diagnosed with KCOT (by tissue biopsy before surgical treatment) with/without nevoid basal cell carcinoma syndrome (NBCCS) from 1995 to 2015. Data were recorded and analyzed statistically to determine the treatment-outcome correlation...

The hippocampus (HPC) has been widely implicated in the contextual control of appetitive and aversive conditioning. However, whole hippocampal lesions do not invariably impair all forms of contextual processing, as in the case of complex biconditional context discrimination, leading to contention over the exact nature of the contribution of the HPC in contextual processing. Moreover, the increasingly well-established functional dissociation between the dorsal (dHPC) and ventral (vHPC) subregions of the HPC has been largely overlooked in the existing literature on hippocampal-based contextual memory processing in appetitively-motivated tasks...

BACKGROUND: Temporomandibular disorder (TMD) incidences are believed to be related to parafunctional behaviors like teeth clenching. OBJECTIVES: This pilot study aimed to (i) develop an automated clench-detection algorithm, and (ii) apply the algorithm to test for differences in nocturnal clenching in women with and without TMD. METHODS: Subjects gave informed consent to participate. Adult women were categorized using Diagnostic Criteria for TMD according to presence/absence (+/-) of both TM joint disc placement (DD) and chronic pain (P) into two groups (+DD+P, -DD-P) with 12 subjects each...

The present study examined the effect of meals varying in amount, size, and hardness of food pieces on the development of the chewing capabilities of 8-month-old infants. The study also examined changes in shivering, gagging, coughing, choking, and their ability to eat from a spoon. In an in-home setting two groups were given commercially available infant meals and fruits, purees with either less, smaller and softer or more, larger and harder pieces. Both groups were given these foods for 4 weeks and were monitored several times during this period...

The Mce systems are complex ABC transporters that are encoded by different numbers of homologous operons in Actinobacteria. While the four Mce systems of Mycobacterium tuberculosis are all energized by a single ATPase, MceG, each system appears to import different fatty acids or sterols. To explore if this behavior can be extended to saprophytic mycobacteria, whose more complex genomes encode more Mce systems, we have identified and characterized the MceG ortholog of Mycobacterium smegmatis. This bacterium relies on MceG to energize its 6 Mce systems that contribute to a variety of cellular functions including sterol uptake and cell envelope maintenance...

Lesion-deficit association studies are important as they can reveal brain regions essential for specific functions, but sometimes appear to yield conflicting results. We aimed to show how pitfalls of lesions studies can be avoided, and converging results obtained, illustrating from studies of the role of posterior superior temporal gyrus in auditory word comprehension. We review published lesion studies on auditory comprehension and present new data from both acute and chronic stroke that address weaknesses in some previous studies...

This study describes the preparation of composite film using chitosan (CS) and polyvinylpyrrolidone (PVP) with incorporated cellulose nanowhiskers (CNWs) for drug delivery application. CNWs were prepared by acid hydrolysis of cellulose with sulfuric acid. Field emission scanning electron microscopy studies revealed nanofibrous morphology of CNWs with 20-30 nm diameter and 200-250 nm in length. X-ray powder diffraction (XRD) analysis confirmed highly crystalline nature of CNWs with 92.81% crystallinity. Incorporation of CNWs enhanced the thermal and mechanical properties of films...

Tyramine is an important neurotransmitter, neuromodulator, and neurohormone in insects. In honeybees, it is assumed to have functions in modulating sensory responsiveness and controlling motor behavior. Tyramine can bind to two characterized receptors in honeybees, both of which are coupled to intracellular cAMP pathways. How tyramine acts on neuronal, cellular and circuit levels is unclear. We investigated the spatial brain expression of the tyramine receptor AmTAR1 using a specific antibody. This antibody detects a membrane protein of the expected molecular weight in Western blot analysis...

Cannabinoid receptors mediate short-term retrograde inhibition of neurotransmitter release, as well as long-term depression of synaptic transmission at excitatory synapses. The responses of individual nerve terminals in VGLUT1-pHluorin transfected cerebellar granule cells to cannabinoids have shown that prolonged activation of cannabinoid type 1 receptors (CB1Rs) silences a subpopulation of previously active synaptic boutons. Adopting a combined pharmacological and genetic approach to study the molecular mechanisms of CB1R-induced silencing, we found that adenylyl cyclase inhibition decreases cAMP levels while it increases the number of silent synaptic boutons and occludes the induction of further silencing by the cannabinoid agonist HU-210...

Analysis of glycosylation is challenging due to micro- and macro-heterogeneity of the protein attachment. A combination of liquid chromatography with tandem mass spectrometry is one of the most powerful tools for glycopeptide analysis. In this work, we show the effect of various monosaccharide units on the retention time of glycopeptides. Retention behavior of several glycoforms of six peptides obtained from tryptic digest of haptoglobin, hemopexin and sex hormone binding globulin was studied on a reversed phase chromatographic column...

Pediatric glaucoma surgery is challenging because of the differences in anatomy from the adult, differences in the behavior of the tissues of a child's glaucomatous eye, the variety in causes of the disease, and difficulties with postoperative management. Goniotomy and trabeculotomy are the preferred initial treatments for primary congenital glaucoma. Trabeculectomy with adjunctive mitomycin C is more likely to succeed in older, phakic patients, but carries the long-term risk of bleb-associated endophthalmitis...

BACKGROUND: Considering the diversity of feeding habits that females of some species of anophelines present, it is important to understand which vertebrates are part of blood food sources and how important is the role of each in the ecoepidemiology of malaria. There are many vector species for Plasmodium spp. in the State of Maranhão, Brazil. In São Luís Island, Anopheles aquasalis is the main vector for human malaria; this species is abundant in areas with primates that are positive for Plasmodium...

Earthworms enhance soil functioning and are, therefore, key species in the soil. Their presence is generally a positive sign for a terrestrial ecosystem, as these species serve as important biomarkers in soil quality evaluations. Here, we describe a novel bioassay, named "dispersal assay," that is a simple and rapid technique for field-based soil quality evaluations. This bioassay was designed based on the premise that earthworms prefer optimal soils if given the choice. Thus, assay tubes containing a reference soil were inserted in target sites, and earthworms were placed into these tubes...

The use of engineered silver nanoparticles (AgNP) is widespread, with expected release to the terrestrial environment through the application of biosolids onto agricultural lands. The toxicity of AgNP and AgNO3 (as ionic Ag(+) ) to plant (Elymus lanceolatus and Trifolium pratense) and soil invertebrate (Eisenia andrei and Folsomia candida) species was assessed using silver-amended biosolids applied to a natural sandy loam soil. Bioavailable Ag(+) in soil samples was estimated using an ion-exchange technique applied to KNO3 soil extracts while exposure to dispersible AgNP was verified by single particle-ICP-MS and TEM-EDS analysis...

Organismal traits such as ecological specialization and migratory behavior may affect colonization potential, population persistence, and degree of isolation, factors that determine the composition and genetic structure of communities. However, studies focusing on community assembly rarely consider these factors jointly. We sequenced 16 nuclear and one mitochondrial genes from Caucasian and European populations of 30 forest-dwelling avian species that represent diverse ecological (specialist-generalist) and behavioral (migratory-resident) backgrounds...
