Small RNAs have a big impact on regeneration. (2/139)

A number of lower vertebrates including urodele amphibians and teleost fish are remarkably adept at repairing and regenerating damaged tissues and organs. Freshwater planarians are even more amazing, capable of regenerating entire body plans from small amputated fragments. In contrast, mammalian regenerative capacity is quite limited but of intense interest, especially related to human health and disease. For those organisms capable of robust regeneration, a common theme is the use of stem cells to replace complex tissues. Key questions remain as to the origin of these cells, whether there are pools of such cells that migrate to injured regions or whether they are generated on site. Beyond their origin, how are the genetic pathways that enable differentiation into multiple cell types and tissues regulated? microRNAs (miRNAs) are small noncoding RNAs that have recently been shown to play important roles in controlling stem cell self-renewal, proliferation and differentiation. Some of these are thought to be required to maintain "stemness". Here, we summarize recent work on the role of miRNAs in stem cells and their roles during regeneration.  (+info)

Pathological study on the scuticociliatosis affecting farmed Japanese flounder (Paralichthys olivaceus) in Japan. (3/139)

Pathological findings associated with scuticociliatosis in farmed Japanese flounder in Japan are described. Ten moribund fishes, farmed in Tottori Prefectural Fisheries Experimental Station, showed cutaneous ulcers, darkened skin, fin and tail rot, exophthalmia and alterations in swimming behaviour. Histopathologically, severe epidermal degeneration and necrosis, hyperplasia of branchial epithelium, myositis, myelitis, encephalitis associated with heavy accumulation of scuticociliates in the periorbital cavity and optic nerve fiber were observed. Moreover, masses of ciliates were found to feed on the host tissues such as skeletal muscles, gills and brain, causing severe degenerative changes associated with abundant neutrophilic and lymphocytic infiltration. These findings suggest that the present scuticociliate, Miamiensis avidus, is a highly invasive and destructive pathogen infecting Japanese flounder and capable of developing systemic fatal infection.  (+info)

Zebrafish have the capacity to regenerate several organs, including the heart and fins. Fin regeneration is epimorphic, involving the formation at the amputation plane of a mass of undifferentiated, proliferating mesenchymal progenitor-like cells, called blastema. This tissue provides all the cell types that form the fin, so that after damage or amputation the fin pattern and structure are fully restored. How blastema cells remain in this progenitor-like state is poorly understood. Here, we show that the Notch pathway plays an essential role during fin regeneration. Notch signalling is activated during blastema formation and remains active throughout the regeneration process. Chemical inhibition or morpholino-mediated knockdown of Notch signalling impairs fin regeneration via decreased proliferation accompanied by reduced expression of Notch target genes in the blastema. Conversely, overexpression of a constitutively active form of the Notch1 receptor (N1ICD) in the regenerating fin leads to ...

Vertebrate limb regeneration occurs in anamniotes such as newts, salamanders, and zebrafish. After appendage amputation, the resection site is covered by a wound epidermis capping the underlying mature tissues of the stump from which the blastema emerges. The blastema is a mass of progenitor cells that constitute an apical growth zone. During outgrowth formation, the proximal blastemal cells progressively leave the zone and undergo the differentiation that results in the replacement of the amputated structures. Little is known about the mechanisms triggering regenerative events after injury. The zebrafish caudal fin provides a valuable model to study the mechanisms of regeneration. Zebrafish blastemal cells express specific genes, such as the homeobox-containing transcription factors msxB and msxC, and secreted signal FGF20a. In this study, we set out to identify signals that are transcriptionally upregulated after fin amputation and before blastema formation. Accordingly, a gene encoding a ...
Sexually dimorphic breeding tubercles (BTs) are keratinized epidermal structures that form clusters on the dorsal surface of the anterior rays of zebrafish male pectoral fins. BTs appear during sexual maturation and are maintained through regular shedding and renewal of the keratinized surface. Following pectoral fin amputation, BT clusters regenerate after the initiation of revascularization, but concomitantly with a second wave of angiogenesis. This second wave of regeneration forms a web-like blood vessel network that penetrates the supportive epidermis of BTs. Upon analyzing the effects of sex steroids and their inhibitors, we show that androgens induce and estrogens inhibit BT cluster formation in intact and regenerating pectoral fins. Androgen-induced BT formation in females is accompanied by the formation of a male-like blood vessel network. Treatment of females with both androgens and an angiogenesis inhibitor results in the formation of undersized BT clusters when compared with females ...
A fin is a thin component or appendage attached to a larger body or structure. Fins typically function as foils that produce lift or thrust, or provide the ability to steer or stabilize motion while traveling in water, air, or other fluid media. Fins are also used to increase surface areas for heat transfer purposes, or simply as ornamentation. Fins first evolved on fish as a means of locomotion. Fish fins are used to generate thrust and control the subsequent motion. Fish, and other aquatic animals such as cetaceans, actively propel and steer themselves with pectoral and tail fins. As they swim, they use other fins, such as dorsal and anal fins, to achieve stability and refine their maneuvering. Foil shaped fins generate thrust when moved, the lift of the fin sets water or air in motion and pushes the fin in the opposite direction. Aquatic animals get significant thrust by moving fins back and forth in water. Often the tail fin is used, but some aquatic animals generate thrust from pectoral ...

Sharks are among the most threatened of marine species worldwide due to unsustainable overfishing. They are primarily killed for their fins alone, to fuel the growing demand for shark fin soup, which is an Asia delicacy. A new study by University of Miami (UM) scientists in the journal Marine Drugs has discovered high concentrations of BMAA in shark fins, a neurotoxin linked to neurodegenerative diseases in humans including Alzheimers and Lou Gehrig Disease (ALS). The study suggests that consumption of shark fin soup and cartilage pills may pose a significant health risk for degenerative brain diseases.. "Shark fins are primarily derived through finning, a practice where by shark fins are removed at sea and the rest of the mutilated animal is thrown back in the water to die," said co-author Dr. Neil Hammerschlag, research assistant professor of Marine Affairs & Policy and director of the RJ Dunlap Marine Conservation Program (RJD) at UM.

Sitting on the back of many fishes, in between the dorsal fin and the tail, is an enigmatic little fatty flap of skin called the adipose fin. It looks a bit like an extra dorsal fin, and though its present in eight large groups of fishes, no one knows why its there. It might help prevent flow from wrapping over the top of the fish; it might help counteract forces from the anal fin, which is in about the same place, but on the ventral side; it might be a flow sensor; or it might not do anything, persisting due to developmental constraints. Whatever the fins function, most fisheries scientists think its not terribly important, because they regularly snip it off to mark millions of hatchery fish released into the wild each year..

Matrix metalloproteinases (MMPs) play key roles in the turnover of extracellular matrix (ECM) and, thereby, function as key regulators of cell-ECM interactions during development. In spite of their importance during developmental processes, relatively little has been reported about the role of these metalloproteinases during limb development and regeneration. To approach the problem of cell-ECM interactions during limb (fin) regeneration, we have utilized zebrafish as an experimental model. Based on previous MMP cloning studies from our laboratory, the current study has focused on the expression of membrane-type 1 metalloproteinase (MT1-MMP), gelatinase A (MMP-2) and endogenous tissue inhibitor 2 of metalloproteinases (TIMP-2) during fin regeneration in adult zebrafish. In situ analysis indicated co-expression of zmt1-mmp, zmmp-2, and ztimp-2 mRNA transcripts in regenerating caudal fins. In situ gelatin-zymography confirmed the presence of active metalloproteinases in regenerating fins. zmt1-mmp, zmmp-2
Retinoic acid (RA) is a key signal involved in the posteriorization of vertebrate neural ectoderm. The major enzyme involved in biosynthesis of RA during embryonic development is retinaldehyde dehydrogenase 2 (Raldh2). A zebrafish mutant in raldh2 (neckless; nls), which is devoid of RA signalling during embryonic development, exhibits anterior-posterior (AP) patterning defects in the neural ectoderm. Using the nls mutant I found that loss of RA also affects AP patterning of the cranial mesoderm. I depleted RA signalling in embryos and found that markers of the posterior cranial mesoderm are shortened along the AP axis, correlating with the severity of RA depletion. I determined the timing for requirement of RA to establish the AP-level of the posterior border of head mesoderm. Together with the pattern of raldh2 expression, I conclude that during gastrulation, RA biosynthesis in prospective mesoderm is a key signal for the specification of the AP extent of the posterior cranial mesoderm. ...
The zebrafish fin is composed of multiple bony fin rays. Each fin ray is comprised of multiple segments separated by joints. Regulatory mechanisms that control joint morphogenesis and ray segment length in zebrafish fins are not fully understood. We utilize the fin length mutants short fin (sof b123) and another long fin (alf dty86) to provide insight into these processes. The sof b123 mutant has short fins and short segments due to a mutation in the gap junction protein gene connexin43 (cx43). In contrast, the alf dty86 mutant has long fins, long segments, and over-expression of cx43. Thus, the two mutants exhibit two opposing phenotypes. For example, the sof b123 mutant exhibits reduced cx43 mRNA and the alf dty86 mutant exhibits increased cx43 mRNA. Cx43 knockdown in alf dty86 rescues the segment length phenotype suggesting that Cx43 activity regulates joint formation. These data suggest that Cx43 is involved in two independent pathways: promoting cell division and suppressing joint formation. This

Locomotor strategies in terrestrial tetrapods have evolved from the utilisation of sinusoidal contractions of axial musculature, evident in ancestral fish species, to the reliance on powerful and complex limb muscles to provide propulsive force. Within tetrapods, a hindlimb-dominant locomotor strategy predominates, and its evolution is considered critical for the evident success of the tetrapod transition onto land. Here, we determine the developmental mechanisms of pelvic fin muscle formation in living fish species at critical points within the vertebrate phylogeny and reveal a stepwise modification from a primitive to a more derived mode of pelvic fin muscle formation. A distinct process generates pelvic fin muscle in bony fishes that incorporates both primitive and derived characteristics of vertebrate appendicular muscle formation. We propose that the adoption of the fully derived mode of hindlimb muscle formation from this bimodal character state is an evolutionary innovation that was ...

Kemeny is the first Fins coach to win the honor. USA swimming breaks age groups down into the following: 8 years and under, 9-10 years old, 11-12 years old, 13-14 years old and 15-plus. Because the Fins are a small team, Kemeny oversees all five groups. He was named coach of the year for his work with the teams younger swimmers.. The Fins had eight age group sectional qualifiers, 10 all-state swimmers and 27 state qualifiers this season. They placed fifth at the SC Short Course Swim Championships in February, earning 37 individual top-three finishes.. The senior swimmers produced one junior national qualifier and four senior sectional qualifiers. "Its an impressive list," said Mary Reed, mother of Fins swimmer Greg Reed. "Were a small team that accomplished big things thanks to Eric." Reed, who was present at the banquet, called Kemenys reaction "priceless" as he heard his name announced.. "Because of his humble nature, it took a moment for it to sink in that he won," said Theresa Wall, ...

The torpedo scad is a moderately large fish, growing to a maximum recorded length of 80 cm and a weight of 4 kg, however is more common between 30 to 40 cm length. It is rare at lengths greater than 80 cm. The species is often considered to have a rather unusual body form, having features superficially similar to tunas, mackerels and other carangids. The body is elongate and subcylindrical, becoming highly compressed toward the tail and caudal fin, with a marked median keel on the caudal peduncle. The dorsal and ventral profiles of the fish are nearly evenly convex, with the two profiles intersecting at the pointed snout. There are two separate dorsal fins; the first consisting of 8 moderately high spines and the second of a single spine followed by 18 to 20 soft rays. The anal fin consists of two anteriorally detached spines followed by a single spine attached to 16 or 17 soft rays. In both the dorsal and anal fins, the posterior 7-10 rays are detached and form a series of diagnostic finlet. ...
A Bugarach, petit village de lAude censé échapper à lapocalypse, la fin du monde na finalement pas eu lieu. La tant attendue soirée du 21 décembre 2012 a plutôt pris des airs de carnaval et laissé place à quelques hurluberlus venus profiter de loccasion pour faire la fête.

It was nice to see that they tossed in a mention of Elpistostege. As you can see, Elpistostege is a lot like Tiktaalik, which is why Tiktaalik is dubbed an "elpistostegalian". Elpistostege is known only very incomplete remains, the limbs have been entirely unknown. However, its tetrapod affinities have been recognized since its discovery in 1938, when T.S. Westoll actually called it the earliest known tetrapod! In 1985, Hans-Peter Schultze and Marius Arsenault recognized it for what it was, a very tetrapod-like fish, similar to Panderichthys. In 1996, Schultze described a short pice of the trunk that has rhomboid-shaped schales and a few vertebrae. What little is known of its skull and trunk of Elpistostege is scarcely different from Tiktaalik. However, after decades of searching no new data on Elpistostege ever came to light. Shubin and Daeschler wanted more of this animal, but knew that the original locality wasnt going to give up its secrets. So, they went looking in similar-aged rocks ...
If you are going to try and build a system with no fans. You should seek a power supply with the highest efficiency and active power factor correction and orient it so that air easily able to flow in and out. In terms of heatsink orientation, the fins going in a vertical direction is at least 30% better than horizontally if not greater at higher fin densities. When trying to promote passive convection, one should increase the fin spacing to allow the buoyancy of air to take effect. If the fins are too close the boundary layers of air flowing over the fin will merge and result in poor heat transfer. Lapping your heatsinks and using minimal TIM would be highly advised. I use a very small amount, barely visible on each surface. If you are using any sort of graphics card i would highly suggest rotating the atx board 90 degrees so that the graphics card is vertical instead of having all the hot air pile up next to the heatsink. As long as your fins are vertical, and you allow a passage for cool air ...
The sun gives you the best vitamin D with no possibility of overdose. Your body regulates the D you get from the sun, so you could be getting 80,000 iu a day from the sun, but you will never develop D toxicity. Its for this reason that I use the sun. Another problem is that people think that going in the sun at 9 am or 5 pm is going to give them D. It will NOT! It will actually deplete your D. This is because the sun exudes UVA rays, and UVB rays. UVA rays are constant, from the moment the sun is in the sky until it sets. UVB rays are not constant. They are significant at around 11 am, peak at 12:30 or 1 pm, and after 3, are mostly non-existent. Yet UVB rays are the ones that make vitamin D. UVA rays actually deplete it. So the sun has its own built-in system to regulate vitamin D. This is why to get vitamin D from the sun, it must be between 11 am and 2 or 3 pm. Im not talking get an all out tan. For most people, 10-20 minutes of unprotected exposure 3 times a week is all you need. This ...
The present invention provides a prosthetic implant 1 which includes a stem 2 having two lateral fins 20. The lateral fins 20 extend outwardly from the lateral side 6 of the stem 2, such that the lateral face 21 of each fin 20 is flush with the lateral side 6 of stem 2.

During development, expression of the Hoxa and Hoxd genes in zebrafish fins and mouse limbs are regulated via a conserved chromatin structure. However, zebrafish lack certain regulatory elements required to produce digits, revealing that radials-the fins bony elements-are likely not homologous to tetrapod digits.

The two top rays are probably not in phase. Their rows of marchers dont line up in matching rows. This is partly because the ray to the right has been shifted by the reflection at the bottom of the film. But it has also travelled farther than the other ray.. If the rows happen to be in phase, the marchers will all line up, and the light will constructively interfere. It will appear twice as bright as a single ray, since both rays are combined.. If the rows are completely out of phase, the light will destructively interfere. The tops of the waves of one ray will fill in the troughs of the second ray, and all we have is flat, with no waves. No waves means no light, and the rays disappear.. Somewhere in between those two extremes, we will get some light, but not as much as two rays worth.. What is important to notice at this time is that there are two things we can do to adjust the phase of the rays, to make them either constructively or destructively interfere at our command.. The first thing we ...
There currently exist a dozen described Esomus specie,s although few are seen in the ornamental trade and none are especially popular. Most are commonplace in their native countries but are generally overlooked by collectors due to their relatively plain colouration. Their most common use in some areas is actually as a feeder fish in the aquaculture of larger species. They are characterised by greatly-enlarged pectoral fins and two pairs of barbels, of which the maxillary pair are extremely long and usually reach the pectoral fins.. In recent years a number of phylogenetic studies involving Esomus and its near relatives have been conducted and conflicting results published. For example a 2003 study by Fang et al. concluded that the genus is the sister group, i.e., most closely-related to, Danio whereas Mayden et al. (2007) placed the genera Chela, Microrasbora, Devario and Inlecypris as sisters to Danio with Esomus as a basal sister group to that larger clade.. A further analysis by Fang et al. ...

Sleeper goby I have a sleeper goby this is the only name I have . I would like to find the scientific name. It is bluish gray on the body , top fin is edged in red , lower fins are edged in white and behind the gill fins , his eyes are a very cloudy blue , he can be hand fed but at times has to make 2 or 3 tries to get the food into his mouth ( I think he has very poor vision) his tank has a pot large enough for him to hide in but he prefers to hide behind it vertically , he is very peaceful . he will eat anything but favors frozen blood worms , frozen brine shrimp and dried Tubifex worms.

Fineness: Its typically shown in the so-called "super wide range." You know, "super 150s" and the like. Two things are consider: First, the extremely wide range signifies the brilliance of the person materials. As the greater the wide range, the thinner the fabric material and the better and silkier the cloth material. Second, wool acquires more rarer the better it is, so especially great supers - 180s and above - are costly. But that doesnt make them healthier, actually. They can be wrinkle-prone, and they show signs of wear - such as shininess - beginning. ...

Statistical Investigations 377 At this point in his paper Galton draws attention to a "Common Error in Statistics," which he says has not hitherto attracted attention. It occurs in a classification, such as "65-" for stature, which is assumed to mean 65 inches and less than 66 inches. He points out that the centre of this group is usually taken as 65.5 inches, but that this is most often erroneous, and that the true centre of the group (if we arrange the group uniformly over its range) may differ very considerably from this. The true centre depends on the fineness of our readings. If, for example, we read stature to the nearest half-inch only, then all measurements in excess of 64.5 would be included in 65, and all measurements in excess of 65.5 in 66. The former would all appear in "65-" and the latter would not. Thus the centre of "65-" would be actually the centre of the range 64.5 to 65.5 or 65 and not 65.5. In other words, there would be half an inch error in the resulting mean. Most tyros ...

A heat sink has a base plate to be clamped against a heat source and one or more heat pipes containing a phase change fluid. Each heat pipe has an elongated tubular evaporator fitted in a channel in the base plate, and a columnar condenser part perpendicular to the base plate forming a structural column for air heat exchange fins. The channel in the base plate is parallel to an edge. An additional channel or ridge is provided, also parallel to the edge, for receiving a clamp or spring clip to urge the base plate against the heat source. The base plate is inexpensively extruded with the parallel channels, ridges, etc., extending across the width of the base plate parallel to the edge. The heat sink has a minimum number of inexpensive parts yet is highly thermally efficient.

Shark finning is the practice of cutting off a sharks dorsal fin so that people can use it for shark fin soup or other "delicacies". The sharks are often still alive while their fins are cut off with no regard to their pain. They are then tossed back into the ocean where, bleeding and in pain, they either suffocate from lack of mobility or are eaten by other sea predators.. Shark populations have been decimated by finning and many species are nearing extinction. Ecosystems are being upset by the lack of sharks in their waters and we are coming dangerously close to no longer having these beautiful creatures in continued decades.. We are calling for the Idaho State Senate to pass legislation that bans the sale, dsitribution, trade and possession of shark fins. The other West coast states have all passed legislation against shark fins, including Hawaii, Washington, Oregon and California. We want Idaho to join the West coast in becoming more compassionate, thoughtful and responsible in regards to ...
While the soup remains a popular delicacy at weddings, the campaigns of groups like WWF Hong Kong seem to be working.. Last year the Chinese government announced to plans to stop serving shark fin soup at official ceremonies, while earlier this summer various businesses like HSBC and Shangri-La Hotels made a pledge to forbid it at events in China and Korean Air Lines swore off transporting shark parts for consumption. Now the Hong Kong region, also known as the worlds capital of shark fin imports, will ban the dish at all official events and request that government employees refrain from eating it anywhere at any time.. Some say this is all a PR stunt by Hong Kong apparatchiks to convince people that civil servants dont live extravagant lifestyles fueled by the perks of working within the Communist party. Others say its just another nail in the industrys coffin after millions boycotted the soup inspired, at least in part, by these advocacy groups educational campaigns.. While we admire the ...
The evolutionary transition of fins to limbs involved development of a new suite of distal skeletal structures, the digits. During tetrapod limb development, genes at the 5′ end of the HoxD cluster are expressed in two spatiotemporally distinct phases. In the first phase, Hoxd9-13 are activated sequentially and form nested domains along the anteroposterior axis of the limb. This initial phase patterns the limb from its proximal limit to the middle of the forearm. Later in development, a second wave of transcription results in 5′ HoxD gene expression along the distal end of the limb bud, which regulates formation of digits. Studies of zebrafish fins showed that the second phase of Hox expression does not occur, leading to the idea that the origin of digits was driven by addition of the distal Hox expression domain in the earliest tetrapods. Here we test this hypothesis by investigating Hoxd gene expression during paired fin development in the shark Scyliorhinus canicula, a member of the most basal
Is the United States a world leader in shark conservation? You may have thought so, but it recently proposed to backtrack on progress achieved over the past several years. The federal government is proposing a rule that, if approved as is, has the potential to overturn the shark protections passed by California, Delaware, Hawaii, Illinois, Maryland, Oregon, Washington state, American Samoa, Guam, and the Northern Mariana Islands.. California has been a significant market for shark fin in the past, which was the catalyst for enactment of AB 376, state legislation that prohibits the possession, sale, and distribution of detached shark fins after the point of landing in California. This legislation became effective in 2013, and it is critical that it is upheld to help reduce the US market for shark fin. NOAAs proposed measure puts this hard-fought legislation at risk, as it seeks to overturn laws prohibiting shark fin trade in favor of more traditional fisheries management measures, which could ...
Developmental and reproductive effects of 17β-estradiol (E2) exposure on two generations of fathead minnows and one generation of bluegill sunfish were assessed. Fish were exposed to E2 for six continuous weeks in outdoor mesocosms simulating natural lake environments. First generation fish were exposed while sexually mature. Second generation fathead minnows were exposed either during early development, sexual maturity, or both stages. Multiple endpoints were measured to assess effects of E2 exposure on fecundity and fish health and development. Plasma vitellogenin concentrations were highly variable in all fish. Differences in egg production timing for both species indicate differences in fecundity between females exposed to E2 and controls. First generation fathead minnows exposed to E2 had lower body condition factors and reduced secondary sexual characteristic expression by males. Only a difference in relative liver weight was observed in second generation fathead minnows. First generation

The behaviour evident for the various North Atlantic Fin Whale populations following earlier reductions by whaling differs. It ranges from clear evidence of recovery to no firm indications of any increase. An estimated 14,000 Fin Whales were killed off northern Norway during 1876-1904, and a further 1,500 during 1948-71, but Fin Whales are rare there now (although quite abundant off western Spitsbergen, where about 1,500 whales had been killed during 1904-11) (Øien 2003, 2004). An estimated 12,000 Fin Whales were killed off Iceland during 1890-1915, until whaling was suspended partly due to concerns about the reductions in the stocks, but the modern abundance data suggest that the there has been a recovery in the population that may still be continuing, particularly west of Iceland, despite catches during 1948-89 averaging about 220 per year (Branch and Butterworth 2006). An estimated 10,000 Fin Whales were taken from the Faeroes, but about 25% of these were actually caught off eastern Iceland ...
The ability to form a regeneration blastema, which leads to the epimorphic regeneration of complex body structures, is restricted to some amphibians and fish among vertebrates (Poss et al., 2003). A conundrum of regenerative biology is why mammals, with a few exceptions, do not form a blastema or a blastema-like structure despite the fact that they can functionally repair some tissues, such as skeletal muscle (Charge and Rudnicki, 2004) and liver (Fausto and Campbell, 2003). Of particular interest is whether the generation of progenitor cells during epimorphic regeneration in salamander and during mammalian tissue repair proceeds by the activation of different or overlapping mechanisms. A unique feature of blastema formation in salamanders is the process of dedifferentiation of stump tissues that follows appendage removal. The possibility to induce blastema formation and regeneration in mammals through the activation of a comparable dedifferentiation program has been proposed (Hughes, 2001; ...

  • Elise Walters '16 (Hunsaker Student Science Researcher) focused her capstone project on identifying bottlenose dolphins by their dorsal fins to estimate their number locally. (redlands.edu)
  • Foster spoke to CNN by telephone from a sailboat in the Aegean Sea, where he and his team have been tracking the animals' progress with the help of transmitters attached to the dolphins' dorsal fins. (cnn.com)
  • Even during my brief stay in Gerlache Strait, I was able to recognize the same three pod members out of more than 20 animals due to their distinctive dorsal fins: One was missing the tip of the fin, one had lost most of the fin and one had a nick out of the rear edge. (japantimes.co.jp)
  • Ten years ago, University of Chicago organismal biologist Neil Shubin discovered the fossils of the 375-million-year-old Tiktaalik roseae, a water-to-land transitional fish that had limb-like fins. (washingtonpost.com)
  • But when you look at a modern fish, it's hard to imagine just how how fins like theirs evolved into the hands, wrists and fingers that you and any other four-limbed animal on earth has. (washingtonpost.com)
  • But now researchers examining an ancient (and still living) species of fish have found the common genetic link between fins and hands. (washingtonpost.com)
  • Researchers examined the switches controlling genes related to the development of fins in the gar fish and hands in mice. (washingtonpost.com)
  • Make the relevant comparisons and we find that our hands resemble fossil fish fins, our heads are organized like long-extinct jawless fish, and major parts of our genomes look and function like those of worms and bacteria. (edge.org)
  • While studying 380 million year old rocks in Ellesmere Island, at a latitude of 80 North, I was uncovering one of the key transitional stages in the shift from fish to land living animal. (edge.org)
  • Everybody knows that fish swim with fins and animals that walk on land have legs. (edge.org)
  • Overall, there are over 25 000 species of fish with these ray-strengthened fins. (biologists.org)
  • This architecture enables a fish to control the motion of each individual ray and thus achieve three-dimensional fin deformations. (biologists.org)
  • During fin regeneration, the arteries and veins form a net-like vasculature called the vascular plexus, and this plexus undergoes remodeling to form a new artery and two flanking veins. (mpg.de)
  • Fin amputation strongly promoted the regeneration of nearby sensory axons, an effect that could be mimicked by ablating a few keratinocytes anywhere in the body. (nih.gov)
  • These exclusively marine animals are characterized by bilateral body symmetry , a prominent head, and a set of arms or tentacles ( muscular hydrostats ) modified from the primitive molluscan foot. (wikipedia.org)
  • These sightings will inevitably play an important role in improving our knowledge of these animals and significantly aiding in the rescue of stranded dolphins in the future! (ifaw.org)
  • Using the homocercal mode, our results demonstrate that the anisotropic deformability of the ray-reinforced fin significantly increases its capacity of force generation. (biologists.org)
  • independent, immature animal that undergoes a profound change, or metamorphosis, to assume the typical adult form. (thefreedictionary.com)
  • These are four-wheel-drive animals, not just front-wheel-drive only," paleontologist Ted Daeschler of the Academy of Natural Sciences said in January . (washingtonpost.com)
  • the head and foot are at one end of an elongated body and function as the anterior (front) of the animal. (wikipedia.org)
  • Make sure fins and flipper are directed out and away from the animal in a natural way, not crushed beneath the body. (wikihow.com)
  • Amputation caused immediate degeneration of axon branches near the wound (Figure 1B, brackets), creating a denervated zone that regenerating axons would need to traverse to fully innervate the regenerating fin. (nih.gov)
  • Despite this potential barrier, the fin was always reinnervated by RB arbors at 120 h post-amputation (hpamp) (Figure 1B). (nih.gov)
  • Three days after fin amputation, there was no detectable difference in the total amount of sensory axons in regenerated fin tips and fin tips of age-matched animals (6 dpf) that were never injured, indicating that reinnervation of regenerated fins was complete (Figure 2A). (nih.gov)
  • But mice have far more genetic switches related to hands and fingers than gar have for their fins. (washingtonpost.com)
  • Spending time taking personal pictures or inviting others to pet the animal will minimize the time spent helping it, cause the animal to feel stressed, and put other people at risk. (wikihow.com)
  • Taking pictures of beached animals for scientific purposes is encouraged, but it should be done with care from a safe distance. (wikihow.com)
  • This property is expected to have fundamental effects on the hydrodynamic performance of the fins in generating propulsion force during cruising, bursting and maneuvering. (biologists.org)
  • Breakthroughs in genetics are beginning to tell us how bodies are built, in essence giving insights into the recipe that builds animals from a single celled egg. (edge.org)
  • He was held as a solitary animal for many of those years," Foster said. (cnn.com)
  • We unlock our history as we understand more about our DNA, as we compare ourselves to animals living and dead, and as we discover new fossils from around the world. (edge.org)
  • Interestingly, both times this animal has been sighted, there has been no sign of the other animals that originally stranded and were released on the same day, giving us insight in the group dynamics of these animals which still remains a mystery! (ifaw.org)
  • With this second report, we have solid confirmation that this animal is doing well! (ifaw.org)
