Applications of Laser Spectroscopy Constitute a Vast Field, Which Is Difficult to Spectroscopy Cover Comprehensively in a Review
LASERS & OPTICS 151 many cases non-destructively. A variety of beam manipulation schemes are avail able for the irradiation of samples either directly or after preparation. The unique properties of laser radiation in terms of coherence, intensity and directionality permit remote chemical sensing, where the analytical equipment and the sample are separated by large distances, even of several kilometres. Absorption, and in particular differential absorption, can be utilised in long-path measurements, whereas elastic and inelastic backscatter- ing as well as fluorescence can be used for range-resolved radar-like measure ments (LIDAR: light detection and rang ing). Laser light can also be efficiently transported in optical fibres to remotely located measurement sites. Various prop erties of the fibre itself influence the laser light propagating through the fibre, thus Applications of Laser forming a basis for fibre optic sensors.

What You Can Do to Reduce Your Exposure to Chemicals
WHAT YOU CAN DO TO REDUCE YOUR EXPOSURE TO CHEMICALS Eat organically grown food whenever possible. Many pesticides and herbicides are carcinogenic, and many have a chemical structure that is very similar to estrogens. These can stimulate the growth of breast tumors. Organic food is grown without chemicals or hormones and has been found to be much higher in nutrients than foods grown in commercially fertilized, nutrient-depleted soil. Especially, avoid non-organic eggs, dairy products and meats, as hormones and antibiotics are fed to the animals. The following fruits and vegetables have been found to have the highest levels of pesticides (when grown non-organically.) Avoid them unless they are organic: strawberries, bell peppers, spinach, cherries, peaches, cantaloupe, celery, apples, apricots,green beans, Chilean grapes, cucumbers. Foods that tend to be low in pesticides EWG analysis of the latest government test results shows that the following fruits and vegetables have the least pesticide contamination among conventionally-grown foods. Fruits Vegetables 1) Pineapples 1) Avocado 2) Plantains 2) Cauliflower 3) Mangoes 3) Brussels Sprouts 4) Bananas 4) Asparagus 5) Watermelon 5) Radishes 6) Plums 6) Broccoli 7) Kiwi Fruit 7) Onions 8) Blueberries 8) Okra 9) Papaya 9) Cabbage 10) Grapefruit 10) Eggplant Do not use pesticides or herbicides in your home or on your lawn or garden. Lawn and garden chemicals have been found to increase cancer rates in pets and people. Avoid Plastics if possible: Their production releases chlorinated toxins into the environment. Reduce or eliminate the use of plastic containers for food storage. Certain plasticizers, which add flexibility to plastic food wraps, are suspected endocrine disrupters. -
November 21, 2018 to the CIR, I Am Writing to Provide Comments on the Revised Aerosol CIR Precedents Document. I Greatly Apprec
November 21, 2018 To the CIR, I am writing to provide comments on the revised Aerosol CIR Precedents document. I greatly appreciate the extensive discussions and considerations of my previous comments on this issue. However, I remain concerned that 1) the boilerplate language continues to make broad assumptions and conclusions of safety about the inhalation of cosmetic products that are not supported by the data. 2) the narrow focus on just hairsprays and aerosol deodorants is severely limiting, given the numerous other cosmetic products that come in spray form, which may have considerably different ingredients, exposure levels and use frequencies. 3) the boilerplate language regarding exposure to cosmetic powders has not been updated, and still reflects assumptions of safety based solely on talc data from 1979, which is not only outdated but is likely not reflective of all cosmetic exposures. 4) the citations for several of the newly included calculation examples do not correspond to the relevant papers and should be corrected and, 5) while there is more nuanced discussion in the background section of the Precedent document, the actual boilerplate language includes the following sentence: “Particle/droplet size data under consumer use conditions are rarely needed when assessing the inhalation safety of an ingredient in a spray cosmetic product.” I believe this assertion, which could be included in isolation in a safety assessment, reflects poorly on the scientific understanding of the CIR. 1) The boilerplate language continues to make broad assumptions and conclusions of safety about the inhalation of cosmetic products that are not supported by the data. At the very beginning of the Cosmetics Use Section of the boilerplate language it states: “In practice, 95% to 99% of the droplets/particles released from cosmetic sprays have aerodynamic equivalent diameters >10 μm [IF PRODUCT(S) MAY INCLUDE BOTH PROPELLANT AND PUMP SPRAYS, ADD: , with propellant sprays yielding a greater fraction of droplets/particles below 10 μm compared with pump sprays]. -

Propylene Glycol
PROPYLENE GLYCOL Your patch test result indicates that you have a contact allergy to propylene glycol. This contact allergy may cause your skin to react when it is exposed to this substance although it may take several days for the symptoms to appear. Typical symptoms include redness, swelling, itching, and fluid-filled blisters. Where is propylene glycol found? Propylene glycol is used as a softening agent, preservative, humectants, and solvent in cosmetics, fragrances, topical medications, soaps and cleansers, hair care products, and deodorants. Propylene glycol is also found in oral treatments as well as many foods. It is also added during the manufacture of many industrial fluids, such as solvents, thinners, antifreeze, other de-icing fluids, desiccants, brake fluids, and polyester resins. How can you avoid contact with propylene glycol? Avoid products that list any of the following names in the ingredients: • Propylene glycol • 1,2-Dihydroxypropane • CASRN: 57-55-6 • Methylethyl glycol • 1,2-Propanediol • 2-Hydroxypropanol • Isopropylene glycol What are some products that may contain propylene glycol?

Many great things can be said about Doctor Goldman. I’m not eloquent enough to do justice for him in this regard, and won’t restate the many well deserved eulogies that have already been dedicated to him. I do find it particularly appropriate to dedicate this manual on “Laser Biophysics and Safety” to Doctor Goldman. He was the original course director for this program of the ASLMS. It was the first formal course I ever took on the “Biomedical Laser” and his first or second time to ever teach it.

Application of 2PA materials includes fluorescence imaging, microfabrication, 3D data storage, photodynamic therapy, etc. Many materials have good 2PA photophysical properties, among which, the fluorenyl structure and its derivatives have attracted attention with their high 2PA cross-section and high fluorescence quantum yield. Herein, several compounds with 2PA properties are discussed. -
Lasers in Skin Cancer Treatment Podcast Audio Transcription
Lasers in Skin Cancer Treatment Podcast Audio Transcription Opening Welcome to Light Talk. A podcast series exclusively for members of the American Society for Laser Medicine and Surgery. Light Talk supports the mission of ASLMS which is to promote excellence in patient care by advancing biomedical application of lasers and other energy-based technologies world-wide. We hope you enjoy this edition of Light Talk with our host, Dr. Nazanin Saedi. Discussion DR. NAZANIN SAEDI Hi, I’m Nazanin Saedi and I am here today with Dr. Anthony Rossi who is an assistant attending at Memorial Sloan Kettering Cancer Center. Anthony, thank you so much for joining us. DR. ANTHONY M. ROSSI Thanks for having me. DR. SAEDI So, Anthony, can you tell us a little bit about your research in using lasers to treat skin cancers? We often think of surgical options for our skin cancer patients, but how do lasers play a role? DR. ROSSI Sure so, you know, for certain patients who have early skin cancers like early superficial basal cell carcinomas, or squamous cell carcinoma in situ, some of these can be amenable to be treated with lasers instead of your traditional surgical approach. So, it’s really important to understand which ones to select and which ones not to treat. Right? We don’t want to treat very deep invasive, infiltrative basal cell with a very superficial laser because we will be missing the deeper component. But for these early lesions, and for patients who don’t necessarily want to have surgery, treating them with a CO2 laser which is what I have been doing, guided by confocal microscopy can really help us hone in on the areas that are positive and then ablate that tissue and then, which is really important, is follow up with them to make sure they aren’t having any regrowth.
