A single type of olfactory sensilla on maxillary palps in many species of mosquitoes houses a very sensitive olfactory receptor neuron (ORN) for carbon dioxide reception. We performed extensive single sensillum recordings from this peg sensillum in Culex quinquefasciatus and have characterized the response threshold and kinetics for CO(2) reception, with a detection threshold less than the CO(2...

The canine tooth is important both functionally and aesthetically, being positioned between the anterior posterior teeth. upper has longest eruption path, forming in deepest part of maxillary bone often experiencing disorders, leading to significant aesthetic functional issues. Early detection management impaction are crucial pediatric dentistry, which focuses on growth eruption. prevalence ran...

In this study, stress of traumatized incisor and the effect of stress on tooth and alveolar bone was studied with two-dimensional photoelasticity. Two homogeneous two-dimensional maxillary central incisor models were prepared. Loads were applied to the labial side of incisal edge and middle third of the crown at angles of 45 degrees and 90 degrees. It was observed that stress was increased on t...

The Cretaceous family Cretapsychidae Wichard, 2021 belongs to the superfamily Sericostomatoidea Stephens, 1836 and is characterized by five-segmented maxillary palps, with second segment being longest following three segments becoming successively smaller, tibial spur formula 2/2/4. In addition, wing venation apical forks II, III, V in forewings I, hindwings. two newly described species (C. kac...

OBJECTIVE The aim of this study was to determine the optimal loading conditions for pure intrusion of the six maxillary anterior teeth with miniscrews according to alveolar bone loss. METHODS A three-dimensional finite element model was created for a segment of the six anterior teeth, and the positions of the miniscrews and hooks were varied after setting the alveolar bone loss to 0, 2, or 4 ...

Midline diastema between maxillary central incisors is a common occurrence, especially in primary and mixed dentition. Its presence has been attributed to genetic and/or environmental factors. However, it is often a normal characteristic of growth. Many times the development of upper midline diastema is related to the presence of hypertrophic or inferiorly attached upper labial fraenum and/or i...

The Drosophila adult head mostly derives from the composite eye-antenna imaginal disc. The antennal disc gives rise to two adult olfactory organs: the antennae and maxillary palps. Here, we have analysed the regional specification of the maxillary palp within the antennal disc. We found that a maxillary field, defined by expression of the Hox gene Deformed, is established at about the same time...

The regulatory regions of homologous genes encoding esterase 6 (Est-6) of Drosophila melanogaster and esterase 5B (Est-5B) of Drosophila pseudoobscura show very little similarity. We have undertaken a comparative study of the pattern of expression directed by the Est-5B and Est-6 5'-flanking DNA to attempt to reveal conserved elements regulating tissue-specific expression in adults. Esterase re...

The objectives of this study were to evaluate (1) the impact of maxillary incisor inclination on the aesthetics of the profile view of a smile, (2) to determine the most aesthetic inclination in the profile view of a smile and correlate it with facial features, and (3) to determine if dentists, orthodontists, and laypeople appreciate differently incisor inclination in smile aesthetics. A smilin...
