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 organs and organ systems constantly adjust to internal and external changes through a process called homeostasis (steady state). These changes might be in the level of glucose or calcium in blood or in external temperatures. Homeostasis means to maintain dynamic equilibrium in the body. It is dynamic because it is constantly adjusting to the changes that the bodys systems encounter. It is equilibrium because body functions are kept within specific ranges. Even an animal that is apparently inactive is maintaining this homeostatic equilibrium.. ...

Nudibranchs (/ˈnjuːdɪbræŋk/) are a group of soft-bodied, marine gastropod molluscs which shed their shells after their larval stage. They are noted for their often extraordinary colours and striking forms, and they have been given colourful nicknames to match, such as Clown, Marigold, Splendid, Dancer and Dragon. Currently, about 2,300 valid species of nudibranchs are known. The word nudibranch comes from the Latin nudus, naked, and the Greek βραγχια, brankhia, gills. Nudibranchs are often casually called sea slugs, as they are a family of Opistobranchs (sea slugs), with the phylum Mollusca (molluscs) but many sea slugs belong to several taxonomic groups which are not closely related to nudibranchs. A number of these other sea slugs, such as the photosynthetic Sacoglossa and the colourful Aglajidae, are often confused with nudibranchs. Nudibranchs occur in seas worldwide, including in the tropics and the Southern Ocean. Nudibranchs live at virtually all depths of salt ...
Nudibranchs are gastropods that have naked branches (gills) hanging off their backs (hence the nudi), many with outlandish color schemes that appear to be a defense mechanism. But their alien characteristics are not just that they look stranger than anything that sci-fi has yet to produce. Some nudibranchs are Borg-like, assimilating weaponry and technology of other species into their own toxic arsenals. Many nudibranchs eat critters that have toxic weapons (stingers, nematocysts, poisons) then secrete the previously digested arsenal when attacked ...
A dorsal fin is classified as a medial, unpaired fin that is located on the midline of the backs of some aquatic vertebrates. In development of the embryo in teleost fish, the dorsal fin arises from sections of the skin that from a caudal fin fold.[4] The larval development and formation of the skeleton that support the median fins in adults result in pterygiophores. The skeletal elements of the pterygiophore includes basals and radials. The basals are located at the base of the dorsal fin, and are closest to the body. The radials extend outward from the body to support the rest of the fin.[4] These elements serve as attachment sites for epaxial muscles.[5] The muscles contract and pull against the basals of the pterygiophores along one side of the body, which helps the fish move through water by providing greater stability.[5] In these types of fish, the fins are made of 2 main components.[5] The first component is the dermal fin rays known as lepidotrichia, and the endoskeletal base with ...

Two pore segment channel 2 (TPC2) is a human protein encoded by the TPCN2 is a protein which in humans is encoded by the TPCN2 gene. TPC2 is an ion channel, however, in contrast to other calcium and sodium channels which have four homologous domains, each containing 6 transmembrane segments (S1 to S6), TPCN1 only contains two domain (each containing segments S1 to S6). TPC2 is homologous to TPC1, the best characterized member of the TPC family. The structure of a TPC1 ortholog from Arabidopsis thaliana has been solved by two laboratories. The structures were solved using X-ray crystallography and contained the fold of a voltage-gated ion channel and EF hands. Genetic knockout and pharmacological inhibition experiments demonstrate that Two-pore Channels, TPC1 and TPC2, are required for infection by Filoviruses Ebola and Marburg in mice.

Identifying Features:. Dendronotus rufus have rectangular bodies with cerata that branch out at the edges. Their bodies are generally white and often have colors on the ends of the cerata. They are usually red, dark brown, or a light pink. They are sometimes known as the Giant Red Sea Slug, because of their size.. Habitat:. The Red Dendronotid is usually found in the South Alaskan waters down to north Washington. They are mostly found in sub-tidal waters.. Prey:. All known nudibranchs are carnivorous. Nudibranchs usually eat live prey such as soft corals, sea pens, and gorgonians, and will often starve to death in captivity without the appropriate foods.. Predators: There is no documented information on what hunts the Red Dendronotid, but generally certain fish, turtles, sea stars, and a few species of crabs prey on these animals.. Reproduction: Nudibranchs are hermaphrodites, and can mate with any member of their species. When mating, two nudibranchs come together side by side and pass sperm ...

Proboscis lateralis is a rare congenital malformation of nose. A case has been reported with tubular process arising just above the inner canthus of left e
The Dlx5 and Dlx6 genes encode homeodomain transcription factors essential for the proper development of limbs in mammalian species. However, the role of their teleost counterparts in fin development has received little attention. Here, we show that dlx5a is an early marker of apical ectodermal cells of the pectoral fin buds and of the median fin fold, but also of cleithrum precursor cells during pectoral girdle development. We propose that early median fin fold establishment results from the medial convergence of dlx5a-expressing cells at the lateral edges of the neural keel. Expression analysis also shows involvement of dlx5a during appendage skeletogenesis. Using morpholino-mediated knock down, we demonstrate that disrupted dlx5a/6a function results in pectoral fin agenesis associated with misexpression of bmp4, fgf8a, and1 and msx genes. In contrast, the median fin fold presents defects in mesenchymal cell migration and actinotrichia formation, whereas the initial specification seems to occur
Fish keep their dorsal fins clamped down when they are stressed. This can usually be rectified with up to 30% water change including gravel vacuuming. The ammonia level has probably risen to a dangerous level in the tank. Cut down on the amount of food given. Goldfish do not have a digestive system. Much waste is created.

It looks like simple mounds of earth from ground level, but when archaeologist Robert Benfer looked at Google Earth images of Peru, he discovered that they look like orcas, condors, and even a duck. Archaeological evidence at the sites pegged the mounds at more than 4,000 years old - making them the oldest animal-shaped structures made by man: Benfer discovered the mounds while looking at satellite photos of a site about which hed long held suspicions. The feature seemed shaped like a condor, he said, b...

Another cool gene all my strains carry is the double tail gene, my all time favorite. A Double Tail betta (dt) has two tail lobes instead of one. It also has twice (sometimes more) as many rays in the dorsal fin (top fin) as a regular Single Tail (ST) betta, resulting in a dorsal fin that is twice (or more) larger than a ST betta. Yes, you get twice as much for the price of one! hehehehe. The ideal Double Tail betta is one with two large even lobes (such as the yellow betta to the left, born in my fishroom and with which I started my Gorgeous Yellow line). Notice how even both lobes are, and how the entire finnage looks like a perfect circle. This is an outstanding Double Tail. DT is recessive, but ST bettas that carry the DT gene have better finnage and larger dorsals then bettas who dont carry DT. Pretty much all my ST bettas carry the DT gene. (indicated by the symbol: ST/dt). ...

The mutualistic association between the squid Euprymna scolopes and the bacterium Vibrio fischeri is an emerging experimental system for the study of the influence of bacteria on animal development. Taking advantage of the ability to raise both this host and its microbial partner independently under laboratory conditions, we describe the effects of bacterial interactions on morphogenesis of the juvenile host symbiotic organ. Our results show that bacteria are essential for normal postembryonic development of the symbiotic organ, which involves changes in both the surface epithelium and the epithelial tissue within the organ where the bacterial culture will take up residence. Cell death induced by exposure to symbiotic V. fischeri results in the regression of a complex ciliated surface epithelium, a tissue that apparently functions to facilitate inoculation of the juvenile organ with the appropriate specific bacterial species. Regression of this tissue begins within hours of exposure to ...

The developmental changes bobtail squid undergo when colonized by the bacteria are both dramatic and accessible for biologists to study. The bobtail squid, Euprymna scolopes, hatches as a fully formed squid. They have no larval stage. However, theres a vestige of the ciliated structures seen in other mollusks. (Cilia are like tiny hairs on the surface of individual cells.) These ciliated cells cover the surface of a pair of appendages in the undeveloped light organ (Koropatnick, 2014). After hatching, the bobtail squid has no association with any bacteria, and is not capable of luminescence. The light organ can only complete its development once it is colonized by a specific species of bacteria, Vibrio fischeri. Once V. fischeri is obtained from the surrounding seawater, the bacteria become suspended in mucus and migrate to the light organ. The cells smell their way! They follow a trail of chemical cues left by the squids cells (Koropatnick, 2014). Approximately 12 hours after hatching, the ...

Lateral proboscis is a rare congenital anomaly. Lateral proboscis is a rare craniofacial malformation characterized by a rudimentary tubular, nose-like structure occurring in association with a wide spectrum of other anomalies. We presented a seven-month-old girl’s lateral proboscis, cleft lip, and palate. Proboscis was excised by an elliptical incision, and the cleft was repaired at the same surgery.
A chela (/ˈkiːlə/), also named claw, nipper, or pincer, is a pincer-like organ at the end of certain limbs of some arthropods.[1] The name comes from Greek (χηλή) through New Latin (chela). The plural form is chelae.[2] Legs bearing a chela are called chelipeds.[3] Another name is claw because most chelae are curved and have a sharp point like a claw. ...
A substantially completely water-soluble and pepsin-digestible protein is obtained by the hydrolysis of the keratin contained in animal structures with saturated steam at a pressure of from about 50 to about 250 p.s.i.g. or higher and from about 5 to about 30 parts of liquid water per part of the keratin source, by weight, at the temperature of saturated steam at the pressure employed. Conversion of the keratin to soluble protein and meal is about 80%; the yield of water-soluble protein being as high as about 70%. The water-soluble protein is an excellent animal food.
Members of the class Cephalopoda are gonochoric. Male and female adults usually die shortly after spawning and brooding, respectively. Mating behavior: Males perform various displays to attract potential females for copulation. During copulation, male grasp the female and inserts the hectocotylus into the females mantle cavity where fertilization usually occurs. Life cycle: Embryos hatch into planktonic stage and live for some time before they grow larger and take up a benthic existence as adults (Ref. 833). ...
