Lipophilization of somatostatin analog RC-160 with long chain fatty acid improves its antiproliferative and antiangiogenic activity in vitro. (1/73)

The therapeutic potential of the somatostatin analogue RC-160 having antiproliferative activity, is limited by its short serum half life. To overcome this limitation, fatty acids namely butanoic acid and myristic acid were conjugated to the N-terminal residue of RC-160. The lipophilized derivatives of RC-160 were synthesized, purified by reverse phase HPLC and characterized by ES-mass spectroscopy. The antiproliferative activity of lipophilized derivatives of RC-160 on the growth of MIA-PaCa2 (human pancreatic carcinoma), DU145 (human prostate carcinoma), ECV304 (human umbilical chord endothelioma), as well as their antiangiogenic activity was evaluated in vitro. The relative stability of myristoyl-RC-160 towards degradation by proteases and serum was also determined. Myristoyl-RC-160 exhibited significantly higher antiproliferative efficacy than RC-160, on the above cell lines (P<0.01). Receptor binding assays, demonstrated that the affinity of RC-160 towards somatostatin receptors remains unaltered by myristoylation. Unlike RC-160, the myristoylated derivative was found to have significantly greater resistance to protease and serum degradation (P<0.01). Myristoyl-RC-160 exhibited significantly greater antiproliferative activity on ECV304, than RC-160 (P<0.01). Myristoyl RC-160 could also inhibit capillary tube formation more efficiently than RC-160 in a dose dependent manner, suggesting that it possessed enhanced antiangiogenic activity in vitro (P<0.001). Lipophilization of RC-160 with long chain fatty acids like myristic acid endows it with improved antiproliferative and antiangiogenic activity, stability and therapeutic index.

Cryo-scanning electron microscopy observations of vessel content during transpiration in walnut petioles. Facts or artifacts? (2/73)

The current controversy about the "cohesion-tension" of water ascent in plants arises from the recent cryo-scanning electron microscopy (cryo-SEM) observations of xylem vessels content by Canny and coworkers (1995). On the basis of these observations it has been claimed that vessels were emptying and refilling during active transpiration in direct contradiction to the previous theory. In this study we compared the cryo-SEM data with the standard hydraulic approach on walnut (Juglans regia) petioles. The results of the two techniques were in clear conflict and could not both be right. Cryo-SEM observations of walnut petioles frozen intact on the tree in a bath of liquid nitrogen (LN(2)) suggested that vessel cavitation was occurring and reversing itself on a diurnal basis. Up to 30% of the vessels were embolized at midday. In contrast, the percentage of loss of hydraulic conductance (PLC) of excised petiole segments remained close to 0% throughout the day. To find out which technique was erroneous we first analyzed the possibility that PLC values were rapidly returned to zero when the xylem pressures were released. We used the centrifugal force to measure the xylem conductance of petiole segments exposed to very negative pressures and established the relevance of this technique. We then analyzed the possibility that vessels were becoming partially air-filled when exposed to LN(2). Cryo-SEM observations of petiole segments frozen shortly after their xylem pressure was returned to atmospheric values agreed entirely with the PLC values. We confirmed, with water-filled capillary tubes exposed to a large centrifugal force, that it was not possible to freeze intact their content with LN(2). We concluded that partially air-filled conduits were artifacts of the cryo-SEM technique in our study. We believe that the cryo-SEM observations published recently should probably be reconsidered in the light of our results before they may be used as arguments against the cohesion-tension theory.  (+info)

Retinal adhesion in light- and dark-adapted rabbits. (3/73)

The effects of pigmentation and light exposure on retinal adhesion in rabbits have been investigated in a complete factorial experiment. Ocular pigmentation did not significantly influence retinal adhesion. A significant difference in retinal adhesive forces was found between light and dark adaptation. The force required to detach the retina from the retinal pigment epithelium was 20 per cent greater in light-adapted eyes than in dark-adapted eyes. These observations suggest that the positional change of rhodopsin molecules in the outer segment disk membranes occurring with light exposure and the resultant alteration in interdisk electrostatic forces may play an important role in retinal adhesion.  (+info)

Global analysis of the Deinococcus radiodurans proteome by using accurate mass tags. (4/73)

Understanding biological systems and the roles of their constituents is facilitated by the ability to make quantitative, sensitive, and comprehensive measurements of how their proteome changes, e.g., in response to environmental perturbations. To this end, we have developed a high-throughput methodology to characterize an organism's dynamic proteome based on the combination of global enzymatic digestion, high-resolution liquid chromatographic separations, and analysis by Fourier transform ion cyclotron resonance mass spectrometry. The peptides produced serve as accurate mass tags for the proteins and have been used to identify with high confidence >61% of the predicted proteome for the ionizing radiation-resistant bacterium Deinococcus radiodurans. This fraction represents the broadest proteome coverage for any organism to date and includes 715 proteins previously annotated as either hypothetical or conserved hypothetical.  (+info)

Generation of the streaming potential by liposomes in cylindrical capillary. Experimental data. (5/73)

A model of creation a streaming potential U as a result of colloidal particle movement in flow in a capillary has been described previously (Zawada 1996) as well as the systems for measurement (Zawada 1990, 1991). The filling of capillary with a solution of liposomes results in a labile adsorbance of liposomes on a capillary glass and changes the measured streaming potential. In order to minimalize these adverse effects, the capillary was covered with phospholipid layer of different composition. Some concentrations of stearylamine as a component of the phospholipid layer may fully compensate the surface charge of the glass capillary and can reduce the liposomes adsorption. The streaming potential of the liposomes solution depends on the ionic strength of the electrolyte and is smaller than the zeta potential for similar liposomes. This suggests that only a part of ions of the liposome ion atmosphere participate in creating of the streaming potential. These are the ions from the hydrodynamic slipping layer. The regression analysis of the relationships between streaming potential U and concentration of liposomes and next ionic strength of the electrolyte gave the value of the surface potential psi0 and the thickness of the hydrodynamic slipping layer d, that is independent of the ionic strength.  (+info)

The shape parameter of liposomes and DNA-lipid complexes determined by viscometry utilizing small sample volumes. (6/73)

A minicapillary viscometer utilizing <0.5 ml of sample at a volume fraction of <0.1% is described. The calculated a/b of DPPC/DPPG multilamellar liposome was 1.14 as prolate ellipsoids and a/b of dioleoylpropyltrimethyl ammonium methylsulfate-DNA complex at a charge ratio of 4:1 (+/-) was 3.7 as prolate ellipsoids or 4.9 as oblate ellipsoids. The deviation of shape from perfect sphere is thus expressed quantitatively in more than two significant figures. In these measurement, the necessary amount of DNA is <0.5 mg.  (+info)

Iohexol in serum determined by capillary electrophoresis. (7/73)

Iohexol, a nonionic compound used as a contrast medium for angiography and as a measure of the glomerular filtration rate, was quantified in serum by capillary electrophoresis. Comparable results were obtained for serum samples deproteinized with acetonitrile or analyzed directly after 50-fold dilution with borate buffer. Serum samples were electrophoresed for 2.6 min at 12 kV in a borate buffer with detection at 254 nm and with 3-isobutyl-1-methylxanthine as internal standard. Acetonitrile deproteinization gave a greater sensitivity than did sample dilution. Between-run CVs were between 4.7% and 6.7%, and within-run CVs were between 2.5 and 3.2%. Analytical recoveries were 95-105%. Results of the method compared well with those by high-performance liquid chromatography (slope 0.96, intercept 0.005 g/L). This method demonstrates the potential of capillary electrophoresis for rapid and simple quantification of small molecules.  (+info)

High-pressure fluorescence correlation spectroscopy. (8/73)

We demonstrate that a novel high-pressure cell is suitable for fluorescence correlation spectroscopy (FCS). The pressure cell consists of a single fused silica microcapillary. The cylindrical shape of the capillary leads to refraction of the excitation light, which affects the point spread function of the system. We characterize the influence of these beam distortions by FCS and photon-counting histogram (PCH) analysis and identify the optimal position for fluorescence fluctuation experiments in the capillary. At this position within the capillary, FCS and photon-counting histogram experiments are described by the same equations as used in standard FCS experiments. We report the first experimental realization of fluorescence fluctuation spectroscopy under high pressure. A fluorescent dye was used as a model system for evaluating the properties of the capillary under pressure. The autocorrelation function and the photon count distribution were measured in the pressure range from 0 to 300 MPa. The fluctuation amplitude and the diffusion coefficient show a small pressure dependence. The changes of these parameters, which are on the order of 10%, are due to the pressure changes of the viscosity and the density of the aqueous medium.  (+info)

Supplement The capillary action pertains to the movement of a liquid through a narrow space as a result of the forces of cohesion, adhesion, and surface tension. Cohesion is the sticking together of alike molecules whereas adhesion is the sticking together of unlike molecules. Surface tension is the intermolecular attraction that pulls the molecules of the liquid inward from the surface resulting in the least surface area possible. These forces work together and produce a capillary action. If a capillary tube is made of glass or any other substance that is polar, water will spontaneously climb up inside it without having to be pumped in any way. The smaller the tube, the higher the water climbs. The attraction is so great between the water molecules and the molecules of the tube that water will climb in defiance of the force of gravity. Capillary action is seen in plants when water is able to ascent from the root upward through the xylem tissues of a plant. Water uptake involving capillary ...
Even though we usually think of water as running downhill, it can indeed flow upwards using a process called capillary action. This is the very scientific principal that explains how water goes from the soil upwards into the stem of plants. Plants contain many vein like tubes that carry water from the plants roots upwards to the plants highest leafs via capillary action. Try this experiment to see capillary action in action.. ...

Capillary action is where the surface tension of the water can pull the water into small gaps. Any gaps in your building that are less than 5mm (1/4″) could allow water into your building. Capillary action is extremely powerful, and can even overcome gravity, allowing water to creep up a detail and into your building. The good news is that its extremely easy to solve. All you need is a gap that is wider than 5 mm (1/4″). If you look at good detailing you will notice that there are often gaps at the bottom of flashings that will prevent water from creeping up the detail.. ...

A sample acquisition device includes a capillary array configured to draw in a sample and retain the sample by capillary action. The capillary array may be coupled to an elongated member, such as a stem or a hollow tube, which defines a longitudinal axis extending in a first direction. In some embodiments, the capillary array defines a major sample acquisition surface that extends in a second direction different than the first direction. A ratio of the major sample acquisition surface area to maximum volume retained by the capillary array may be selected to minimize physical binding between the capillary array and sample. In some embodiments, the device may include a feedback mechanism to indicate the relative pressure applied to a sample source with the sample acquisition device. In addition, in some embodiments, the sample acquisition device may include a suction source to help draw the sample into the capillary array.
A sampling member defines a passageway including an inlet opening for reception of a bodily fluid therein, and a wicking member having a first portion coupled with the sampling member adjacent to the inlet opening. The wicking member further includes a second portion displaced from the first portion for initially contacting the bodily fluid. In use the sampling member is placed adjacent to an incision site with the second portion of the wicking member positioned to have the bodily fluid first contact the wicking member and thereby draw the fluid from the incision site to the inlet opening. In related embodiments there is provided a sampling system and method which further includes a lancing device to create the incision and optionally expression members to urge the bodily fluid from the incision, preferably in an integrated unit.
The present invention relates to the selection of materials which are particularly useful as fluid distribution material for being used in disposable absorbent articles by being characterized in that they have a wicking time of less than 120 seconds and a cumulative flux of more than 0.075 grams/cm2/second for said preferential fluid distribution direction at 12.4 cm height, when applying the Vertical Wicking Test. A further useful selection criteria for such materials is a non-isotropic fluid distribution behavior, expressed in that the wicking time in the preferential distribution direction is less than 80% of the wicking time of perpendicular direction at 8.3 cm height, when applying the same test.
Microsatellite DNA or short tandem repeat (STR) 1 sequences are important in many types of genetic analysis, such as loss of heterozygosity testing, linkage analysis, gene mapping and discovery, paternity and forensic identity testing, evolutionary studies, and clinical diagnostics (1)(2)(3)(4)(5)(6)(7)(8)(9)(10). STR analysis is highly informative because of the large number (,5200) of mapped loci available (11) and because these loci are highly polymorphic and widely distributed across the genome (6). STR analysis usually consists of locus-specific PCR amplification followed by electrophoretic separation of the products (3)(10)(12). Many STR-based genetic studies, such as linkage analysis, gene mapping, and loss of heterozygosity testing, require the screening of large numbers of microsatellite loci in thousands of individuals (1)(3)(4)(5)(10). To address the needs of these and future STR-based studies, new generations of genetic analysis devices and methods that can rapidly perform sensitive, ...

On July 5th, 2004, Jim McKenney brought up the problem of moisture in his raised beds in spite of their being covered and impervious to rain. Two possible solutions might be to treat the bed as a scree similar to those naturally found or constructed in which alpine plants are grown. The size of the beds matter is great enough to allow drainage and air flow to a fair depth, and the moisture below in more dense material (earth) would both evaporate up and be carried by capillary action to a far lesser degree. In fact, watering on occasion might be required. The second technique might be to copy bonsai growers and go for a uniform mixture that is leached to remove all particulate matter smaller than is required for stability and growth. Local conditions would dictate exactly what size matter is used. In my case, Ive gone so far as to use childrens marbles as a base up to a small layer of sifted compost to add some organic matter on top. Watered in once, the compost drifts down far enough to give ...

As noted above, OPG is an endogenous inhibitor of RANKL signaling that limits arterial calcium accumulation during development. Recently, the impact of pharmacological inhibition of RANKL by OPG has been evaluated in the above preclinical models of atherosclerosis and arterial calcification. Interestingly, very distinct responses are observed with OPG administration in LDLR−/− and apoE−/− mice.28,43 Morony et al28 first evaluated the male LDLR−/− mouse, the dynamics of endogenous RANKL/OPG signaling during disease initiation and progression, and the impact of exogenous OPG administration. Serum RANKL measurements demonstrated that progression of vascular disease over 5 months of dietary cholesterol challenge closely tracks the progressive recovery of circulating RANKL after an early phase of diet-induced suppression.28 Early diet-induced increases in OPG, a presumed adaptive mechanism to protect against untoward RANKL signaling,36 exhibited no dynamic change with progression.28 As ...

A fluid delivery system usable in an oral care implement and a reservoir containing a flowable substance. A capillary channel formed of one or more wicking or capillary members extends through at least a portion of the oral care implement to deliver flowable substance(s) through one or more outlets via capillary action. In one embodiment, the rate of fluid flow through the capillary channel is different in at least a first flow section than in a second flow section. In another embodiment, the rate of flow between flow sections of the wicking member is different than in at least one of the flow sections. A variety of flowable substances can be administered for therapeutic, hygienic, and/or other benefits, such as fresh breath, tooth whitening, tooth sensitivity, plaque and/or tartar control, or producing sensations of heat, cool, or tingling.
Consider four points A, B, C and D near the liquid-air interface. Pressure just below the meniscus is less than the pressure just above it by 2T/R.. PB = PA - 2T/R. where T is surface tension at liquid-air interface and R is the radius of concave surface.. But pressure at A is equal to the pressure at D and is equal to the atmospheric pressure P. Pressure at D is equal to pressure at C . Therefore, pressure at B is less than pressure at D.. But the pressure at all points at the same level in a liquid must be same. Thats why water begins to flow from the outside region into the tube to make up the deficiency of pressure at point B. Thus, liquid begins to rise in the capillary tube to a certain height h till the pressure of liquid column of height h becomes equal to 2T/R. Thereafter, water stops rising. In this condition. h ρ g = 2 T/R. where ρ is the density of the liquid and g is the acceleration due to gravity. If r be radius of capillary tube and θ be the angle of contact, then. R = ...
Liquids (such as water) that wet glass climb upward on the surfaces of their containers to form a concave meniscus. This occurs when adhesive solid-liquid intermolecular forces are stronger than liquid forces. Such liquids will rise in a narrow capillary tube until a balance is established between the effects of surface tension and gravity. The capillary rise increases sharply as the tube is made ;

The Occupational Safety and Health Administration (OSHA), the National Institute for Occupational Safety and Health (NIOSH), and the Center for Devices and Radiological Health of the Food and Drug Administration (FDA) have produced a joint advisory notice on the use of glass capillary tubes. This document, Glass Capillary Tubes: Joint Safety Alert about Potential Risks, is designed to inform readers of the potential hazards associated with these devices. An OSHA News Release will be published to notify the public of the safety advisory. FDA and NIOSH will also be disseminating the advisory to the public through their respective agency procedures.. Safer alternatives to conventional glass capillary tubes are described in this advisory. Breakage of glass capillary tubes during use may result in a penetrating wound and blood inoculation to the user. With such an injury comes a risk of acquiring a bloodborne pathogen infection, such as human immunodeficiency virus (HIV), hepatitis B, and hepatitis ...
25-Hydroxycholesterol is steroid derivative that suppresses the cleavage of sterol regulatory element binding proteins (SREBPs). It also induces apoptosis through down-regulation of Bcl-2 expression and activation of caspases. 25-Hydroxycholesterol also enhances Interleukin-1 beta (IL-1beta-induced) IL-8 production.(PMID: 17086498 ). 25-hydroxycholesterol is endogenously produced from cholesterol at early time intervals after cholesterol ingestion. It inhibits HMG-CoA reductase and so it also plays a significant role in the in vivo regulation of cholesterol biosynthesis after an acute dietary cholesterol challenge ...
1 Preparation of glass capillary tubes. Glass capillary tubes (Hilgenberg GmbH,D-34321 Malsfeld; article no. 1400290, Sodaklarglas, length 90 mm, O. D. 1,4 mm, wall 0.261 mm) are rinsed several times in demineralized water, dried, stored in test tubes and autoclaved at 121 C for 20 min, but may be used also without prior washing.. 2 Preparation of capillary holders and plastic straws. For storing the capillaries aluminium tubes or polypropylene tubes are used. They are labelled with the number of the strain preserved by special ink markers (Nalgene Cryo-Marker). If capillaries of more than one strain are to be stored in the same capillary holder, the capillaries are colour coded by putting them into PVC straws cut to length and squeezed together at one end. The accession no. of the strain(s) is written on the straws and the capillary holder. The straws (2 mm in diameter) are available in different colours from A. Albrecht GmbH & Co. KG, D-88323 Aulendorf.. 3 Suspending medium and ...

A distinctive absorbent article includes an absorbent core having multiple absorbent layers, wherein the absorbent layers interact in such a manner which preferentially locates absorbed liquid in an appointed, high saturation wicking layer. The localization of the liquid within this wicking layer increases the potential of this layer to move liquid through capillary action due to the higher saturation level and increased amount of liquid available. In particular aspects, at least one primary layer region can have a heterogeneous structure. In additional configurations, the at least one primary layer region can include a plurality of two or more sublayers.
0096] It has been determined that the clamshell opening speed (i.e., the speed at which the cone is moved away from the cup bottom, the action of which is one step in a sequence required for the extraction of the wafer from the cup/cone clamshell assembly) has an effect on rinsate wicking into the contact area and edge defects. Without being limited by any particularly model or theory, it is believed that slower opening speeds cause less suction in the contact area resulting in reduced wicked amounts. However, further reducing the opening speeds causes the wicking volume to increase, which may be due to capillary action while wafer is waiting to be picked out of the cup. FIG. 14A is a plot of the normalized rinsate volume wicked into the contact area as a function of the opening speeds two different spinning durations. In both tests, a fixed spin rotation speed of 600 rpm was used for either two seconds (line 1402) or four seconds (line 1404). The spinning was performed after a two second rinse ...
Coating the inside of glass microtubes with a polymer hydrogel material dramatically alters the way capillary forces draw water into the tiny structures, researchers have found. The discovery could provide a new way to control microfluidic systems, including popular lab-on-a-chip devices.
where σ12 is the surface or interfacial tension (see Surface and Interfacial Tension) on the boundary between phases 1 and 2, p1 and p2 are the pressures in the phases. The pressure is higher in the phase to which the concavity of the interface is presented. For a plane interface, H=0 and pσ=0. Capillary phenomena include various cases of equilibrium and flow of fluid surface under the action of surface tension forces and of external forces, primarily gravity. In the simplest case when the external forces are absent, e.g., under weightlessness conditions, a limited fluid volume takes the shape of a sphere due to surface tension forces. This state corresponds to a stable equilibrium of the fluid since a sphere has the minimum surface and, consequently, the minimum surface energy. As shown in Figure 1, when the liquid (1) comes in contact with the gas vapor (2) and the solid (3), the shape of the free liquid surface depends on wetting. Interaction of surface tension forces at the liquid-gas ...

So I see a sign next to an elevator which has the floor plan and instructs: In case of fire, do not use elevator. Use stairs. I think hmm, people dont read signs and arent great at reading maps, especially under times of high stress like when there s a fire. (Field 1) And the written instructions arent great either, why dont they just say If theres a fire? Worse, the map is super confusing-I dont know how to read a floor plan at all, and there should just be a set of directions saying Make two lefts to get to the stairs. (Field 2.) I wonder how many lives would be saved if you changed to better signs, and how you could measure it, and how the costs and benefits would add up. (Field 3.) Finally, why is it designed in this particular way? Is it because of a regulation? Or is it because the corporations that put up the signs were cutting corners and it was a little tougher for one person to do it in a better way, or because little details like this are really hard for organizations to ...
The poetry of these children arises from the fact that we find in them all the problems, all the sufferings of the adults, who remain offstage. These children affect us because in a certain sense they are monsters: they are the monstrous infantile reductions of all the neuroses of a modern citizen of industrial civilization….

Following a user-defined protocol the system architecture enables sample aspiration, reagent dispensing, mixing, and thermal cycling, with intermediate imaging steps for in-process monitoring of critical fluid delivery steps. A serial pipeline process is used to provide flexibility, reproducibility, and reliability for the reactions prepared. A typical reaction comprises a 0.5 μL sample aspirated from a ...
The origin and history of the Ashkenazi Jewish population have long been of great interest, and advances in high-throughput genetic analysis have recently provided a new approach for investigating these topics. We and others have argued on the basis of genome-wide data that the Ashkenazi Jewish population derives its ancestry from a combination of sources tracing to both Europe and the Middle East. It has been claimed, however, through a reanalysis of some of our data, that a large part of the ancestry of the Ashkenazi population originates with the Khazars, a Turkic-speaking group that lived to the north of the Caucasus region ~1,000 years ago. Because the Khazar population has left no obvious modern descendants that could enable a clear test for a contribution to Ashkenazi Jewish ancestry, the Khazar hypothesis has been difficult to examine using genetics. Furthermore, because only limited genetic data have been available from the Caucasus region, and because these data have been concentrated ...
The first issue of 2017 of Surface Innovations is available online. We open this first issue with two important contributions prepared by members of the External Advisory Board. In the first paper entitled Contact Angles and Wettability: Towards Common and Accurate Terminology, an international and interdisciplinary team of scientists led by Professor Abraham Marmur define terms describing contact angles, wettability, super-hydrophobicity and similar terminology. In the second contribution to this issue and entitled Application of Thin-Layer Wicking Method for Surface Free Energy Determination, Professor Emil Chibowski and his colleagues summarize theoretical fundamentals of the thin-layer wicking method and provide practical guidelines to this important experimental method used in wetting characterization of powder materials. They also offer directions on determination of solid surface free energy for powder material utilizing the experimental data produced with thin-layer wicking method. ...
We found that carbon nanotubes with diameters smaller than a nanometer bear a key structural feature that enables enhanced transport. The narrow hydrophobic channel forces water to translocate in a single-file arrangement, a phenomenon similar to that found in the most efficient biological water transporters, said Ramya Tunuguntla, an LLNL postdoctoral researcher and co-author of the manuscript appearing in the Aug. 24 edition of Science.. Computer simulations and experimental studies of water transport through CNTs with diameters larger than 1 nm showed enhanced water flow, but did not match the transport efficiency of biological proteins and did not separate salt efficiently, especially at higher salinities. The key breakthrough achieved by the LLNL team was to use smaller-diameter nanotubes that delivered the required boost in performance.. These studies revealed the details of the water transport mechanism and showed that rational manipulation of these parameters can enhance pore ...

DropArray microplates enable simple and easy miniaturization of assays at 2-4 microliters for the 384-well format and 5-15 microliters for the 96-well format because of their unique wall-less design. The wall-less feature eliminates capillary action, the biggest barrier to miniaturization with traditional microplates. Furthermore, the wall-less feature allows extremely gentle washing by liquid exchange, which is different from the harsh, convection-based washing performed by a microplate washer with an array of nozzles.. Unlike a standard microplate that requires dispensing and aspiration from each well, bulk liquids like wash buffers are added to or removed from the entire DropArray microplate at once. By reducing turbulence in wash steps, far fewer cells and beads are lost from the assay droplets, even with suspension cells and non-magnetic beads compared to traditional microplates. Evaporation is controlled using an Anti-Evaporation Lid which provides a humidified environment and minimizes ...

You should dress in light layers for a day of cross country skiing. Clothing suitable for alpine skiing or snowmobiling will be much too warm and bulky for this sport. Cross country skiing is an aerobic sport - you will perspire even in the cold, so dressing appropriately is important. Start with a base layer of long underwear that has a wicking property such as polypropylene (designed to remove moisture from your skin into the fabric where it will evaporate). Follow with an insulating layer (fleece, wool or another fiber which will maintain insulating abilities even when wet and which dry quickly) work well. Finally an outer layer which will repel snow, block wind and allow perspiration to escape and evaporate. Socks should also be made of a wicking fabric. One pair of mid-weight socks is often enough. On very cold days, you will want to add a liner sock next to your skin for layering warmth. And on a related note, be sure your boots fit properly. You will want about a half-inch of space ...
