Amaç: Bu çalışmada menstrual siklusun sağlıklı pulpa duyarlılığına etkisi araştırıldı. Objective: In this study, effect of menstrual cycle on healthy pulp sensitivity was investigated. Materials and methods: Pulpal sensitivity was assessed with electric pulp tester (EPT). The study was performed on 13 dental students without dysmenorrhea (49 teeth). Recordings were taken on four phases of the c...

The objective of the current study was to evaluate the effects of supplement type and feeding frequency on performance, voluntary forage intake, and physiological responses of yearling beef steers. Twenty-four Brahman x British steers were stratified by initial body weight (BW) and randomly allocated to 12 pens (two steers/pen). Pens were randomly assigned to one of three treatments: 1) molasse...

The secreted proteins Wingless and Hedgehog are essential to the elaboration of the denticle pattern in the epidermis of Drosophila embryos. We show that signaling by Wingless and Hedgehog regulates the expression of veinlet (rhomboid) and Serrate, two genes expressed in prospective denticle belts. Thus, Serrate and veinlet (rhom) partake in the last layer of the segmentation cascade. Ultimatel...

Conodont elements are the earliest vertebrate dental structures. The dental tools on elements responsible for food fracture-cusps and denticles-are usually composed of lamellar crown tissue (a putative enamel homologue) and the enigmatic tissue known as 'white matter'. White matter is unique to conodonts and has been hypothesized to be a functional adaptation for the use of elements as teeth. W...

The morphological properties of cellulose nanofibrils obtained from eucalyptus pulp fibres were assessed. Two samples were produced with the same chemical treatment (NaClO/NaBr/TEMPO (2,2,6,6-tetramethylpiperidine-1-oxyl radical) oxidation), but distinct mechanical treatment intensities during homogenization. It was shown that the nanofibrils production yield increases with the mechanical energ...

Tricorythodes molinerii sp. n. is described and illustrated based on nymphs from southeastern Brazil. The new species can be distinguished from other species of Tricorythodes Ulmer by the following characters: 1) genal projection present; 2) maxillary palp bi-segmented, with short apical seta; 3) pronotum with well developed anterolateral projection; 4) dorsum of fore femora with a transverse r...

Lithobius yuchernovisp. n. is described, based on type material from the Ola Plateau, Magadan Region, Russia. The new species is widely distributed in northeastern Siberia, ranging from the Magadan Region, until the eastern Chukot Autonomous Region and the Kamchatka Peninsula in the southeast, whence non-type material is documented. This species belongs to the subgenus Chinobius Matic, 1973 bas...

introduction: many epidemiological studies have been conducted to determine the prevalence of the various types of the dental anomalies. the aim of the present study was determination of developmental and acquired dental anomalies in patients attending the faculty of dentistry in rasht, iran. materials and methods: in this retrospective cross-sectional study, 1224 digital panoramic ra-diographs...

OBJECTIVE The use of stone and plaster study models is an integral part of any dental practice and is required for research. Storage of study models is problematic in terms of space and cost. Ayoub et al.(1) introduced a new technique based on the recent advances in stereophotogrammetry for archiving dental study models in a digital format. However, assessment of the accuracy of the generated t...

Resin acids in many pulp mill effluents are primary sources of toxicity to fish. Inconsistent biological detoxification of chlorinated and nonchlorinated resin acids in secondary treatment of pulp mill effluents is a continuing source of concern. An alternative approach to effluent detoxification is to remove or modify the toxic compounds present in wood chips prior to pulping. Results from exp...
