Fish gills represent a complex organ composed of several cell types that perform multiple physiological functions. Among these cells, ionocytes are implicated in the maintenance of ion homeostasis. However, because the ionocyte represents only a small percent of whole gill tissue, its specific transcriptome can be overlooked among the numerous cell types included in the gill. The objective of this study is to better understand ionocyte functions by comparing the RNA expression of this cell type in freshwater and seawater acclimated rainbow trout. To realize this objective, ionocytes were captured from gill cryosections using laser capture microdissection after immunohistochemistry. Then, transcriptome analyses were performed on an Agilent trout oligonucleotide microarray. Gene expression analysis identified 108 unique annotated genes differentially expressed between freshwater and seawater ionocytes, with a fold change higher than 3. Most of these genes were up-regulated in freshwater cells.
In a three-part series, Luke Mackay explores three types of wild mushroom and their varying virtues. This time, mushrooms with gills Mushrooms with gills are those most likely those imagined when one thinks of a generic mushroom. A central stem, wide domed cap and fleshy spore dropping gills are characteristic of thousands of mushroom varieties. From the classic and common portobellos (agaricus bisporus) to the terrifying amanita virosa, cheerily known in Europe as the destroying angel which will kill you and your dining companions in a heartbeat should you ingest even a tiny morsel in an otherwise safe soup.. Mushroom gills are the thin, papery structures that hang vertically under the cap. The sole purpose of these gills, called lamellae, is to produce spores. The spores are then dropped from the gills by the millions where they are scattered by wind currents. Some recipes call for the gills of edible mushrooms to be removed but I can think of absolutely no good reason why. Perhaps the ...
Definition of gill disease in the Legal Dictionary - by Free online English dictionary and encyclopedia. What is gill disease? Meaning of gill disease as a legal term. What does gill disease mean in law?
In Great Britain, the standard single measure of spirits in a pub was 1/6 gill (23.7 ml) in England, and 1/5 gill (28.4 ml) in Scotland; though this has now been replaced by either 25 ml or 35 ml measures (Landlords can choose which one to serve). The 1/4 gill was previously the most common measure in Scotland, indeed there are pubs in Edinburgh and Glasgow called the The Quarter Gill, which insists on serving whisky by the 1/4 gill (35.5 ml). In southern England it is also called a noggin, but in northern England the large noggin is used, which is two gills. In some areas, a gill came to mean half a pint for both beer and milk. [6]. In Ireland the standard spirit measure was historically 1/4 gill. In the Republic of Ireland, it still retains this value, though it is now legally specified in metric units as 35.5 ml.. ...

An examination is made of the hypothesis that endogenous 5-hydroxytryptamine (5-HT) serves as a local hormone regulating ciliary activity in the lamellibranch gill. These cilia are sensitive to exogenous 5-HT and respond to it by a prompt, sustained, and reversible rise in beat frequency; at the same time the carbohydrate metabolism is stimulated, as described elsewhere. Control gill contains small but definite amounts of endogenous 5-HT according to bioassay, fluorometry, and chromatography. The amount can be increased markedly by exposing the isolated gill to the precursor substance 5-hydroxytryptophan but not l-tryptophan. As the tissue level of 5-HT rises, the spontaneous beat frequency also rises. Both remain elevated for hours and perhaps for days. The gill of Mytilus edulis is richer than the gill of Modiolus demissus in both endogenous 5-HT and effective 5-hydroxytryptophan decarboxylase activity. Modiolus gill lacks the 5-hydroxyindole oxidase by which Mytilus gill destroys 5-HT. What ...

The fatty acid composition and fluidity of gill phospholipids and hemocyte membranes of a eurytherrnal bivalve, Placopecten magellanicus, were investigated following a 10°C reduction in acclimation temperature. The time course of the acclimation response from 15 to 5°C was also monitored over a 21-day period. Membrane physical properties were measured by means of an electron spin resonance (ESR) spin-labeling technique, using 5-doxyl stearic acid (5-SASL) as a probe. Changes in the fluidity of gill membranes were analyzed by incorporating 5-SASL into vesicles made from total gill phospholipid (PL). Membrane fluidity measurements showed that cold-acclimated scallop membranes were more fluid than those of warm-acclimated animals. However, the order parameter of 5-SASL was greatest during the first six days of the reduction in temperature, indicating a more rigid gill membrane structure. The fluidity of gill and hemocyte membranes were negatively correlated with the proportion of 20:5n-3 (r = ...

By lengthening the diastolic period and increasing VSH, hypoxic bradycardia offers two potential advantages in terms of oxygen delivery to a Type I heart.. (a) Hypoxic bradycardia increases blood residence time in the lumen of the heart, which then favours oxygen extraction (Farrell, 1984). Blood residence time in the lumen of the heart will become a critical factor whenever the threshold PvO2 is reached during hypoxia. This benefit is particularly important for the trabecular fish heart because ventricular end-systolic volume (ESV) is much lower than that in mammals, so that the trabeculae become compressed against each other during systole, temporarily increasing the effective oxygen diffusion distance beyond that of a single trabecula. If ESV is zero, oxygen extraction could be prevented altogether. Qualitative studies using angiographic cardiac imaging suggest that ESV is routinely close to zero [e.g. for anaesthetised Channa argus (Andresen et al., 1987)]. For the anaesthetised leopard ...

Insects; Spiracles open in the body, to allow gases to diffuse in. They also help to prevent water loss (just like the Guard Cells of a plant). The Oxygen is delivered directly to tissues via the tracheoles. The tubes are thin and moist, and air is pumped through by the insect to maintain a Concentration Gradient.. Fish; Gills are made up of thin layers of tissue with a rick blood supply. The gills are thin, so there is only a short distance for the necessary gases to diffuse across. Surfaces are always moist.. In bony fish, the gills are contained in a gill cavity. The fish have to keep swimming, so that water is pumped over them to maintain a Concentraion Gradient. Gills cant work in air, due to not having big enough surface areas.. ---------------------------------.

Through photographs, objects and installations Simryn Gill considers how we experience a sense of place and how both personal and cultural histories inform our present moment. Her work also suggests how culture becomes naturalised, an almost invisible part of our physical environment.. Gill often works with books, narratives and texts that provide a framework through which we order and describe the world around us. Forest, has the appearance of an etymological proposition where Gill quite literally takes printed words back to roots. Not their roots, as in the source of their meaning, but rather the growing, evolving, decaying nature from which the raw material for books is derived. Gill tore up the fibrous matter of book pages and grafted fragile strips of text into the natural environment. Attached to tropical plants, they look like natural forms, becoming exuberant banana florescences, dangling aerial roots on fig trees, mangroves emerging from mudflats, variegations on the leaves of lush ...

Introduction. Fish gills remove oxygen from water as human lungs extract oxygen from air. The oxygen content in air is about 20 times greater compared to water. Therefore aquatic animals such as fish, spend about 20 times more energy breathing than air breathers such as humans. This project will determine how temperature affects breathing rates of fish. The purpose of this lab was to observe the opening of the fishs mouth and its operculum (flap covering the gills) to determine the breathing rate of fish at different temperatures. Hopefully, information obtained from this lab can be used by people to keep their pet fish healthy and happy. How does environmental temperature changes affect cellular respiration rate in a goldfish? Hypothesis: The requirement of oxygen for a fish changes with water temperature. As the temperature rises, the metabolism of the fish increases. ...read more. Middle. Use a timer to do this. 6. Repeat step 5 three times. 7. Average the three trials to determine the ...
Copper (Cu) is an essential element required by all living organisms, since at least 30 enzymes are known to use Cu as a cofactor. Cu is also toxic in excess and liver and gills are known to be target organs for it. In the present study, 240 Siberian sturgeon juvenile (with initial weight 29.2 ± 3.1 g and initial length 21.8 ± 1.4 cm) were randomly distributed in 12 fiberglass tanks at 4 different copper nanoparticle (Cu-NPs) treatments with 3 replicates. Treatments included control (T0 = no added Cu-NPs), 50 (T50), 100 (T100), 200 (T200) µg.l-1 Cu-NPs (mean primary particle size of 2 - 6 nm) in a semi-static waterborne exposure regime. Water exchanged were 20% daily with re-dosing after each change. The experimental period lasted 28 days, 14 days exposure to Cu-NPs and 14 days as recovery time. Fish liver, gill, intestine and muscle were sampled at days 0, 7, 14, 21 and 28. Samples were weighed, dried (100 ◦C for 48 h) then digested in concentrated nitric acid in a water bath, cooled, and analyzed
In addition to tracking the pH in fishes under normal physiological conditions, we monitored the pH in comatose and dying individuals. Repeated anesthesia can be associated with intoxication, after which some fish cannot be awakened. The percentage of fish that fell into a coma is probably dependent on the natural variability in the health status of the subjects. The state is caused by oxygen deprivation in the brain, which generally results from poor gill ventilation and decreased heart rate. We applied the chosen anesthesia procedure intentionally to induce significant disturbances in metabolism and show the functionality of pH-sensitive MBMs. The pH values in dead fish were measured just once after death and were excluded from the experiment after the 100 min time point.. The median blood pH in the gills of a comatose fish (7.20) was lower than that in fish at normal state (7.47) when measured 100 min after the injection, but the difference was not statistically significant (P-value=0.072). ...
Chris nearing Combe Gill. After crossing Combe Gill we had a breather. The kids amused themselves by throwing stones from our pathside perch to the gill below, with no other folk about we thought it was a bit of harmless fun until Anna accidentally let one go vertically instead of across and down. With no idea where it would land, we just hunkered down and hoped for the best. After what seemed ages, there was a loud thud and a shower of gravel in the small area around which we were sitting. Lucky, eh? The ensuing rollocking echoed around the fellside but soon we all saw the funny side of it and a course of proper stone-throwing was instigated.. From there it was a simple but delightful walk back to the hostel via Mountain View, over Folly Bridge and along the short via ferrata riverside chain-walk section just as we entered the hostel grounds.. After wed got ourselves showered and changed we booked in for a superb meal at the hostel and chilled for the rest of the evening before turning in ...

Back to the question of whats going on here? The shore crabs did take up microplastics in both types of exposure, but residence time is the key. They were able to clear the microplastics they got through dietary means, but they were still trying to clear microplastics they took up during ventilation almost a month later. The authors constructed a model to explain the mechanism of the movement of the microplastics. They found that the crabs tended to exhibit an asymmetry in microplastic uptake in the gills, which they attributed to the pumping mechanism of the scaphognathite being more dominant on one side of the gill chamber. Also, the posterior gills have a larger surface area than the anterior gills so they are more likely to take up microplastics into their lamellae. The crabs were unable to dislodge the tiny particles by normal gill cleaning actions. It is interesting that no microspheres were found in the hemolymph at any of the sampling points in either experiment. That suggests that ...

My research focuses mainly on the osmoregulatory processes of the gills, since gills are the main site of ion exchange in fish. I explore how survival, plasma osmolality, NKA activity and gene expression at several candidate osmoregulatory loci differ between landlocked and anadromous alewives when challenged in a common salinity environment. Such experiments identify the physiological mechanisms that have diverged between landlocked and anadromous alewives. So far I have shown that landlocked alewives are less tolerant of seawater than anadromous alewives, and have less effective ion secretion mechanisms at the gill. These differences appear to be at least partially driven by changes in the expression of genes that code for ion transporters involved in ion secretion at the gill. Natural selection has likely acted to reduce osmoregulatory function in seawater among landlocked alewives, since it may bear constitutive energetic costs. My current work is aimed at understanding differences between ...

Reposted from Pharyngula. Heres the start of the situation: fish have a problem. Like most animals, they need to maintain a specific internal salt concentration, but they are immersed in a solution that is much more dilute they they are (for freshwater fish) or much more concentrated (for saltwater fish). To make matters worse, fish have large respiratory membranes, the gills, which expose a huge amount of surface area to the watery medium. Their answer to the problem is to do much of their regulation of various ions at the gill surface, using sensors and salt pumps to constantly work, extracting excess salts from one side and pumping them to the other. Gills are therefore more than just the organ fish use to breathe-its also where they regulate salt balance.. Us terrestrial tetrapods have a different problem. We cant pump salts out of or into the air, so instead we maintain internal stores of salts (calcium, for instance, is packed into bone) and use hormones to regulate them, by telling ...
