whoa, buddy! I'm just a friendly AI and I don't have access to real-time databases or personal data, so I can't provide medical definitions or any other specific information about individuals, places, or things. But I can tell you that I couldn't find any recognized medical definition for "Wisconsin" - it's a state in the United States, not a medical term!

IA in Kenyon cells of the mushroom body of honeybees resembles shaker currents: kinetics, modulation by K+, and simulation. (1/578)

Cultured Kenyon cells from the mushroom body of the honeybee, Apis mellifera, show a voltage-gated, fast transient K+ current that is sensitive to 4-aminopyridine, an A current. The kinetic properties of this A current and its modulation by extracellular K+ ions were investigated in vitro with the whole cell patch-clamp technique. The A current was isolated from other voltage-gated currents either pharmacologically or with suitable voltage-clamp protocols. Hodgkin- and Huxley-style mathematical equations were used for the description of this current and for the simulation of action potentials in a Kenyon cell model. Activation and inactivation of the A current are fast and voltage dependent with time constants of 0.4 +/- 0.1 ms (means +/- SE) at +45 mV and 3.0 +/- 1.6 ms at +45 mV, respectively. The pronounced voltage dependence of the inactivation kinetics indicates that at least a part of this current of the honeybee Kenyon cells is a shaker-like current. Deactivation and recovery from inactivation also show voltage dependency. The time constant of deactivation has a value of 0.4 +/- 0.1 ms at -75 mV. Recovery from inactivation needs a double-exponential function to be fitted adequately; the resulting time constants are 18 +/- 3.1 ms for the fast and 745 +/- 107 ms for the slow process at -75 mV. Half-maximal activation of the A current occurs at -0.7 +/- 2.9 mV, and half-maximal inactivation occurs at -54.7 +/- 2.4 mV. An increase in the extracellular K+ concentration increases the conductance and accelerates the recovery from inactivation of the A current, affecting the slow but not the fast time constant. With respect to these modulations the current under investigation resembles some of the shaker-like currents. The data of the A current were incorporated into a reduced computational model of the voltage-gated currents of Kenyon cells. In addition, the model contained a delayed rectifier K+ current, a Na+ current, and a leakage current. The model is able to generate an action potential on current injection. The model predicts that the A current causes repolarization of the action potential but not a delay in the initiation of the action potential. It further predicts that the activation of the delayed rectifier K+ current is too slow to contribute markedly to repolarization during a single action potential. Because of its fast activation, the A current reduces the amplitude of the net depolarizing current and thus reduces the peak amplitude and the duration of the action potential.  (+info)

Interactions between the foot and bud patterning systems in Hydra vulgaris. (2/578)

In the freshwater coelenterate, hydra, asexual reproduction via budding occurs at the base of the gastric region about two-thirds of the distance from the head to the foot. Developmental gradients of head and foot activation and inhibition originating from these organizing centers have long been assumed to control budding in hydra. Much has been learned over the years about these developmental gradients and axial pattern formation, and in particular, the inhibitory influence of the head on budding is well documented. However, understanding of the role of the foot and potential interactions between the foot, bud, and head patterning systems is lacking. The purpose of this study was to investigate the role of the foot in the initiation of new axis formation during budding by manipulating the foot and monitoring effects on the onset of first bud evagination and the time necessary to reach the 50% budding point. Several experimental situations were examined: the lower peduncle and foot (PF) were injured or removed, a second PF was laterally grafted onto animals either basally (below the budding zone) or apically (above the budding zone), or both the head and PF were removed simultaneously. When the PF was injured or removed, the onset of first bud evagination was delayed and/or the time until the 50% budding point was reached was longer. The effects were more pronounced when the manipulation was performed closer to the anticipated onset of budding. When PF tissue was doubled, precocious bud evagination was induced, regardless of graft location. Removal of the PF at the same time as decapitation reduced the inductive effect of decapitation on bud evagination. These results are discussed in light of potential signals from the foot or interactions between the foot and head patterning systems that might influence bud axis initiation.  (+info)

Olfactory adaptation depends on the Trp Ca2+ channel in Drosophila. (3/578)

Olfactory adaptation is shown to occur in Drosophila, at both behavioral and physiological levels. In a behavioral paradigm, the extent of adaptation is shown to depend on the dose and duration of the adapting stimulus. Half-maximal adaptation occurred after 15 sec of exposure to an odor, and recovery occurred with a half-time of 1. 5 min, under a set of test conditions. Cross-adaptation was observed among all odor combinations tested, although to a lesser extent than when the same odor was used as both the adapting and the test stimulus. Mutants of the transient receptor potential (Trp) Ca2+ channel were normal in olfactory response, but defective in olfactory adaptation, when measured either behaviorally or in tests of antennal physiology. These results indicate that olfactory response and adaptation can be distinguished. Trp expression was detected in the developing antenna but, surprisingly, not in the mature antenna. These results, together with temperature-shift analysis of a temperature-sensitive trp mutant, provide evidence of a role of Trp in olfactory system development.  (+info)

A lobster phospholipase C-beta that associates with G-proteins in response to odorants. (4/578)

A cDNA clone encoding a protein of 1116 amino acids with significant homology to beta-isoforms of phospholipase C was isolated from lobster olfactory organ cDNA libraries and named lobPLCbeta. This cDNA hybridized predominantly to a 9 kb transcript in RNA from olfactory organ, pereiopod, brain, and eye-eyestalk and to several smaller minor transcripts only in eye-eyestalk. An antiserum raised to the C terminus of lobPLCbeta detected immunoreactivity in a single 130 kDa band in olfactory aesthetasc hairs, olfactory organ, pereiopod, dactyl, and brain. In eye-eyestalk this 130 kDa band was abundant, and minor bands of 100, 79, and 57 kDa also were detected. In cross sections of the aesthetasc hairs, immunoreactivity was detected in the outer dendritic segments of the olfactory receptor neurons, the site of olfactory transduction. A complex odorant caused lobPLCbeta immunoreactivity to increase in membrane fractions and decrease in soluble fractions of homogenates of aesthetasc hairs. The odorant also increased the amount of lobPLCbeta in immunoprecipitates of Galphaq and Gbeta from homogenates of aesthetasc hairs. These results support the conclusion that lobPLCbeta mediates olfactory transduction.  (+info)

Differential expression of Tbx4 and Tbx5 in Zebrafish fin buds. (5/578)

In here we report the identification of two new members of the T-box gene family, zf-tbx5 and zf-tbx4, from the Zebrafish, Danio rerio. The amino acid sequences within the T-box domain share high homology with the mouse, chick, and newt orthologs. Whole mount in situ hybridization revealed specific expression of these genes in the eye and Fin buds. zf-tbx5 expression is restricted to the pectoral Fin bud, whilst zf-tbx4 transcripts are confined in the pelvic Fin bud. These results reveal the conserved expression pattern of Tbx5 and Tbx4 during appendage development in all animal species studied to date.  (+info)

Response characteristics of an identified, sexually dimorphic olfactory glomerulus. (6/578)

Partitioning of synaptic neuropil into glomeruli is a common feature of primary olfactory centers in most animal species. The functional significance of glomeruli, however, is not yet well understood. The present study is part of our effort to test the hypothesis that each glomerulus is a functional unit dedicated to processing information about a particular odorant or attribute of odor molecules and that the glomerular array constitutes a map of "odor space." We investigated the physiological and morphological features of uniglomerular projection neurons (PNs) associated with an identified glomerulus in each antennal lobe of the female sphinx moth, Manduca sexta. This "lateral large female glomerulus" (latLFG) is sexually dimorphic and therefore may play a female-specific role, such as processing of information about one or more odorants important for orientation of a female to host plants for oviposition. Together with the medial LFG (medLFG), the latLFG resides outside the array of spheroidal ordinary glomeruli, near the entrance of the antennal (olfactory) nerve. Each LFG is innervated by four to five PNs. Using intracellular recording and staining, we examined the responses of latLFG-PNs to odorants that represent major classes of volatiles released by host plants of M. sexta. All latLFG-PNs were excited when the ipsilateral antenna was stimulated with low concentrations of the monoterpenoid linalool. Dose-response analysis showed that neither other monoterpenoids nor representatives of other classes of host plant volatiles were similarly stimulatory to latLFG-PNs. These findings are consistent with the idea that each glomerulus has a characteristic, limited molecular receptive range.  (+info)

amos, a proneural gene for Drosophila olfactory sense organs that is regulated by lozenge. (7/578)

In a variety of organisms, early neurogenesis requires the function of basic-helix-loop-helix (bHLH) transcription factors. For the Drosophila PNS, such transcription factors are encoded by the proneural genes (atonal and the achaete-scute complex, AS-C). We have identified a proneural gene, amos, that has strong similarity with atonal in its bHLH domain. We present evidence that amos is required for olfactory sensilla and is regulated by the prepattern gene lozenge. Between them, amos, atonal, and the AS-C can potentially account for the origin of the entire PNS.  (+info)

Essential roles of Drosophila RhoA in the regulation of neuroblast proliferation and dendritic but not axonal morphogenesis. (8/578)

The pleiotropic functions of small GTPase Rho present a challenge to its genetic analysis in multicellular organisms. We report here the use of the MARCM (mosaic analysis with a repressible cell marker) system to analyze the function of RhoA in the developing Drosophila brain. Clones of cells homozygous for null RhoA mutations were specifically labeled in the mushroom body (MB) neurons of mosaic brains. We found that RhoA is required for neuroblast (Nb) proliferation but not for neuronal survival. Surprisingly, RhoA is not required for MB neurons to establish normal axon projections. However, neurons lacking RhoA overextend their dendrites, and expression of activated RhoA causes a reduction of dendritic complexity. Thus, RhoA is an important regulator of dendritic morphogenesis, while distinct mechanisms are used for axonal morphogenesis.  (+info)

'Animal structures' is a broad term that refers to the various physical parts and organs that make up animals. These structures can include everything from the external features, such as skin, hair, and scales, to the internal organs and systems, such as the heart, lungs, brain, and digestive system.

Animal structures are designed to perform specific functions that enable the animal to survive, grow, and reproduce. For example, the heart pumps blood throughout the body, delivering oxygen and nutrients to the cells, while the lungs facilitate gas exchange between the animal and its environment. The brain serves as the control center of the nervous system, processing sensory information and coordinating motor responses.

Animal structures can be categorized into different systems based on their function, such as the circulatory system, respiratory system, nervous system, digestive system, and reproductive system. Each system is made up of various structures that work together to perform a specific function.

Understanding animal structures and how they function is essential for understanding animal biology and behavior. It also has important implications for human health, as many animals serve as models for studying human disease and developing new treatments.

An encyclopedia is a comprehensive reference work containing articles on various topics, usually arranged in alphabetical order. In the context of medicine, a medical encyclopedia is a collection of articles that provide information about a wide range of medical topics, including diseases and conditions, treatments, tests, procedures, and anatomy and physiology. Medical encyclopedias may be published in print or electronic formats and are often used as a starting point for researching medical topics. They can provide reliable and accurate information on medical subjects, making them useful resources for healthcare professionals, students, and patients alike. Some well-known examples of medical encyclopedias include the Merck Manual and the Stedman's Medical Dictionary.

'Isoptera' is an outdated term for a taxonomic order of social insects commonly known as termites. These eusocial insects are closely related to cockroaches and share some similarities in their appearance, but they have specialized castes including workers, soldiers, and reproductives that live in colonies. Termites feed on wood, plant fibers, and other materials containing cellulose, which they break down with the help of symbiotic protozoa living in their gut. The order Isoptera is no longer recognized by modern taxonomists, who now place termites within the cockroach family Blattodea.

I believe you may have made a typo in your question. "Archaeology" is the scientific study of past human cultures and societies through the recovery, examination, and analysis of material remains such as artifacts, buildings, biofacts (e.g., bones, shells), and cultural landscapes. It is not typically associated with medical definitions. If you intended to ask for a different term related to medicine or healthcare, please let me know so I can provide the correct information.

For more information about archaeology, you may be interested in visiting the World Archaeological Congress () or the Society for American Archaeology () websites to learn more about this fascinating field of study.

Body temperature regulation, also known as thermoregulation, is the process by which the body maintains its core internal temperature within a narrow range, despite varying external temperatures. This is primarily controlled by the hypothalamus in the brain, which acts as a thermostat and receives input from temperature receptors throughout the body. When the body's temperature rises above or falls below the set point, the hypothalamus initiates responses to bring the temperature back into balance. These responses can include shivering to generate heat, sweating to cool down, vasodilation or vasoconstriction of blood vessels to regulate heat loss, and changes in metabolic rate. Effective body temperature regulation is crucial for maintaining optimal physiological function and overall health.

I'm sorry for any confusion, but "spiders" is not a term that has a specific medical definition. It is a common name used to refer to arachnids of the order Araneae, characterized by having two main body parts (the cephalothorax and abdomen), eight legs, and fangs that inject venom.

However, in a medical context, "spider" or "spider bite" may be used to describe skin lesions or reactions resulting from the bite of certain spiders, particularly those with medically significant venoms. For example, necrotic arachnidism is a condition caused by the bite of some spider species, such as recluse spiders (Loxosceles spp.). The bites can cause skin necrosis and other systemic symptoms in severe cases.

If you are looking for information on a specific medical topic or condition, please provide more details so I can offer a more accurate response.

I'm sorry for any confusion, but "Wisconsin" is a U.S. state located in the Midwest and is not a medical term or condition. If you have any medical questions or terms you would like defined, I'd be happy to help with those!

Social behavior, in the context of medicine and psychology, refers to the ways in which individuals interact and engage with others within their social environment. It involves various actions, communications, and responses that are influenced by cultural norms, personal values, emotional states, and cognitive processes. These behaviors can include but are not limited to communication, cooperation, competition, empathy, altruism, aggression, and conformity.

Abnormalities in social behavior may indicate underlying mental health conditions such as autism spectrum disorder, schizophrenia, or personality disorders. Therefore, understanding and analyzing social behavior is an essential aspect of diagnosing and treating various psychological and psychiatric conditions.
