These organisms are the most extensively studied of all genera from the standpoint of genetics and cytology.Drosophila Proteins: Proteins that originate from insect species belonging to the genus DROSOPHILA. The proteins from the most intensely studied species of Drosophila, DROSOPHILA MELANOGASTER, are the subject of much interest in the area of MORPHOGENESIS and development.Odonata: An order of insects comprising three suborders: Anisoptera, Zygoptera, and Anisozygoptera. They consist of dragonflies and damselflies.Hernia, Diaphragmatic: Protrusion of abdominal structures into the THORAX as a result of congenital or traumatic defects in the respiratory DIAPHRAGM.Sense Organs: Specialized organs adapted for the reception of stimuli by the NERVOUS SYSTEM.Pupa: An inactive stage between the larval and adult stages in the life cycle of insects.Lung: Either of the pair of organs occupying the cavity of the thorax that effect the aeration of the blood.Entomology: A discipline or occupation concerned with the study of INSECTS, including the biology and the control of insects.Pleural Cavity: Paired but separate cavity within the THORACIC CAVITY. It consists of the space between the parietal and visceral PLEURA and normally contains a capillary layer of serous fluid that lubricates the pleural surfaces.Funnel Chest: A developmental anomaly in which the lower sternum is posteriorly dislocated and concavely deformed, resulting in a funnel-shaped thorax.Respiratory Mechanics: The physical or mechanical action of the LUNGS; DIAPHRAGM; RIBS; and CHEST WALL during respiration. It includes airflow, lung volume, neural and reflex controls, mechanoreceptors, breathing patterns, etc.Respiration: The act of breathing with the LUNGS, consisting of INHALATION, or the taking into the lungs of the ambient air, and of EXHALATION, or the expelling of the modified air which contains more CARBON DIOXIDE than the air taken in (Blakiston's Gould Medical Dictionary, 4th ed.). This does not include tissue respiration (= OXYGEN CONSUMPTION) or cell respiration (= CELL RESPIRATION).Air Bags: Automotive safety devices consisting of a bag designed to inflate upon collision and prevent passengers from pitching forward. (American Heritage Dictionary, 1982)Antennapedia Homeodomain Protein: Antennapedia homeodomain protein is a homeobox protein involved in limb patterning in ARTHROPODS. Mutations in the gene for the antennapedia homeodomain protein are associated with the conversion of antenna to leg or leg to antenna DROSOPHILA.Short Rib-Polydactyly Syndrome: A syndrome inherited as an autosomal recessive trait and incompatible with life. The main features are narrow thorax, short ribs, scapular and pelvic dysplasia, and polydactyly.Metamorphosis, Biological: Profound physical changes during maturation of living organisms from the immature forms to the adult forms, such as from TADPOLES to frogs; caterpillars to BUTTERFLIES.Thoracic Surgical Procedures: Surgery performed on the thoracic organs, most commonly the lungs and the heart.Pleura: The thin serous membrane enveloping the lungs (LUNG) and lining the THORACIC CAVITY. Pleura consist of two layers, the inner visceral pleura lying next to the pulmonary parenchyma and the outer parietal pleura. Between the two layers is the PLEURAL CAVITY which contains a thin film of liquid.Artifacts: Any visible result of a procedure which is caused by the procedure itself and not by the entity being analyzed. Common examples include histological structures introduced by tissue processing, radiographic images of structures that are not naturally present in living tissue, and products of chemical reactions that occur during analysis.Abdominal Injuries: General or unspecified injuries involving organs in the abdominal cavity.Bronchography: Radiography of the bronchial tree after injection of a contrast medium.Genes, Insect: The functional hereditary units of INSECTS.Shoulder: Part of the body in humans and primates where the arms connect to the trunk.

For example, three-dimensional images can be generated by assembling multiple tomographic images with the aid of a computer, while photographic 3-D images (HOLOGRAPHY) can be made by exposing film to the interference pattern created when two laser light sources shine on an object.Insect Proteins: Proteins found in any species of insect.Lung Neoplasms: Tumors or cancer of the LUNG.Neck: The part of a human or animal body connecting the HEAD to the rest of the body.Hemothorax: Hemorrhage within the pleural cavity.Radiation Dosage: The amount of radiation energy that is deposited in a unit mass of material, such as tissues of plants or animal. In RADIOTHERAPY, radiation dosage is expressed in gray units (Gy). In RADIOLOGIC HEALTH, the dosage is expressed by the product of absorbed dose (Gy) and quality factor (a function of linear energy transfer), and is called radiation dose equivalent in sievert units (Sv).Mediastinal Cyst: Cysts of one of the parts of the mediastinum: the superior part, containing the trachea, esophagus, thoracic duct and thymus organs; the inferior middle part, containing the pericardium; the inferior anterior part containing some lymph nodes; and the inferior posterior part, containing the thoracic duct and esophagus.Larva: Wormlike or grublike stage, following the egg in the life cycle of insects, worms, and other metamorphosing animals.
