Both are characterized by a spherical contour but are decidedly different in size. \nThe gas inclusion porosities are usually much larger than pinhole porosity. Many metals dissolve or occlude gases while they are molten. For example, both copper and silver dissolve oxygen in large amounts in the liquid state. Molten platinum and palladium have a strong affinity for hydrogen as well as oxygen. On solidification, the absorbed gases are expelled and pinhole porosity results. The larger voids may also result from the same cause, but it is more logical to assume that such voids are caused by gas that is mechanically trapped by the molten metal in the mold or by gas that is incorporated during the casting procedure.\nReference: PHILLIPS’ SCIENCE OF DENTAL MATERIALS, 12th ed page no 226" } ]

However, the functional role of this variant in bladder cancer predisposition has been unclear because it lies within a non-coding region of the genome. Here, it is demonstrated that bladder cancer cells heterozygous for this SNP exhibit biased allelic expression of CCNE1 with 1.5-fold more transcription occurring from the risk allele. Furthermore, using chromatin immunoprecipitation assays, a novel enhancer element was identified within the first intron of CCNE1 that binds Kruppel-like Factor 5 (KLF5), a known transcriptional activator in bladder cancer.

Harrison's 18lh/pg. 367)In Pityriasis rosea, initially, there is a single 2- to 6-cm annular salmon-colored patch (herald patch) with a peripheral rim of scale, followed in days to weeks by a generalized eruption involving the trunk and proximal extremities.Pityriasis rosea:# It is an acute, self-limiting skin condition. A primary plaque ('herald patch') is followed by a distinctive, generalized itchy rash 1-2 weeks later. The rash lasts for approximately 2-6 weeks. Lesions are typically oval, dull pink or tawny and appear in a 'Christmas tree' distribution, usually on the trunk and the upper arms and legs.# It is thought that human herpes viruses 6 and 7 may play a role in etiopathogenesis. Some drugs, eg bismuth, barbiturates, captopril, gold, metronidazole, D-penicillamine and isotretinoin occasionally cause a drug-induced pityriasis rosea.# Pityriasis rosea is a self-limiting disease, and treatment is supportive.# Exposure to sunlight is helpful.# Topical zinc oxide and calamine lotion are useful for pruritus.# Pruritus can also be treated with topical corticosteroids, oral antihistamines or antipruritic lotions.# Oral erythromycin may be effective in treating the rash and decreasing the itch.- Pityriasis alba is an uncommon feature of atopic dermatitis that presentsin children and adolescents. Light- coloured skin spots also occur in pityriasis alba (slightly scaly, on skin exposed to the light), Gibert's pityriasis rosea, pityriasis versicolor (Gr. \"pityron\" = bran; refers to the light skin scaliness). Pityriasis versicolor is a very common skin infection with a fungus: Pityrosporum ovale (yeast stage) or Malassezia furfur (mycelium stage). This lipophilic fungus forms the tyrosinase inhibitor azelaic acid from sebaceous fats, a substance which inhibits melanin synthesis. This explains the white appearance of the skin spots. Account must be taken of the fact that depigmented skin spots can also be caused by damage to the melanocytes (pigment cells) after an ordinary infection, wound or bum (post-inflammatory hypopigmentation), due to vitiligo (the texture of the skin with this condition is otherwise normal), as a residual lesion in endemic treponematosis and syphilis (the differential diagnosis is often difficult here). It is important to know that people with leprosy often have a false positive VDRL (screening for syphilis). TPHA permits differentiation.Pityriasis rubra pilaris (also known as \"Devergie's disease,\"or \"Lichen ruber acuminatus,\" and \"Lichen ruber pilaris\"refers to a group of chronic disorders characterized by reddish orange, scaling plaques and keratotic follicular papules.

When correlating the culture pattern of the BM with the data from the leukapheresis products, we observed that the number of the immature progenitors in BM correlated significantly with both the number of CD34 + cells and CFU-GM in the first leukapheresis. Univariate analysis revealed that the following variables had a beneficial impact on the number of CD34+ cells: male sex, body weight >73 Kg, G-CSF schedule and results of LT-BMC, although in the multivariate analysis only the number of CFU-GM obtained after LT-BMC showed a significant influence (p<0.001).'], 'labels': ['OBJECTIVE', 'METHODS', 'RESULTS'], 'meshes': ['Adolescent', 'Adult', 'Aged', 'Antigens, CD34', 'Bone Marrow Cells', 'Cell Culture Techniques', 'Child', 'Female', 'Granulocyte Colony-Stimulating Factor', 'Hematopoiesis', 'Hematopoietic Stem Cell Mobilization', 'Humans', 'Leukapheresis', 'Male', 'Middle Aged', 'Peripheral Blood Stem Cell Transplantation', 'Prospective Studies', 'Tissue Donors']}" }, { "from": "gpt", "value": "Answer: yes" } ]

During strong inspiratory effort it may reach up to -30 mmHg.Transpulmonary pressureIt is the difference between alveolar pressure and intrapleural pressure. It is the measure of elastic forces in the lungs.Alveolar pressure or intrapulmonary pressureIt is the pressure inside the lung alveoli. When no air flows the alveolar pressure is considered to be equal to the atmospheric pressure, i.e., 0 cm of water.During inspiration it decreases to -1 cm of water.During expiration it increases to+1 cm of water." } ]

Nanocrystals exhibit a narrow difference between their excitation and emission peak spectra (Ref: http://www.semrock.com/fluorescence-imaging-with-quantum-dot-nanocrystals. aspx ; style=\"font-size: 1.04761904761905em; font-family: Times New Roman, Times, serif\">; Article ID=2375\"Semiconductor nanocrystals were prepared for use as fluorescent probes in biological staining and diagnostics. Compared with conventional fluorophores, the nanocrystals have a narrow, tunable, symmetric emission spectrum and are photochemically stable. The advantages of the broad, continuous excitation spectrum were demonstrated in a dualemission, single-excitation labeling experiment on mouse fibroblasts. These nanocrystal probes are thus complementary and in some cases may be superior to existing fluorophores\". - Science 25 September 1998: Vol 281 No. 5385 pp2013-2016After much searching we could get some information on the nanocrystals and nanotechnology which could be easy to understand. Most of the material available was quite complicated and beyond our scope.Nanotechnology is the manipulation of matter on an atomic and molecular scale. By convention, nanotechnology is taken as the scale range 1 to 100 nm following the definition used by the National Nanotechnology in the US.One nanometer is one billionth, or 10-9 of a meter. To give a sense of measurement a DNA double-helix has a diameter around 2 nm and the smallest cellular life-forms, the bacteria of the genus Mycoplasma, are around 200 nm in length.Nanocrystals, also called Quantum dots, are inorganic crystals that exhibit very strong fluorescent emissions. These materials are considered semiconductors and range from one to fifty nanometers in diameter.These semiconductor nanocrystals are remarkably durable.The desired behavior and transmission directly correlates to their size. To change the emitted wavelength, the crystal is grown larger or smaller. Their electronic and optical properties can be controlled by this method. For example to change the emission from one visible wavelength to another simply use a larger or smaller grown crystal.The nanocrystal size controls a widely tunable absorption band resultign in widely tunable emission spectra. This tunability combined with the optical stability of nanocrystals and the great chemical flexibility in the nanocrystal growth have resulted in the widespread nanocrystal applications in use today. They have been a mainstay as fluorescent markers in biological and medical research for years. As such, they are usually incorporated into polystyrene beads, mixed into a solution and then incorporated into the biological system.NanotechnologyNanomedicine is the medical application of nanotechnology.http://en.wikipedia.org/wiki/Nanomedicine - cite_note-Nanomed1-1 Nanomedicine ranges from the medical applications of nanomaterials, to nanoelectronic biosensors, and even possible future applications of molecular nanotechnology.The biological and medical research communities have exploited the unique properties of nanomaterials for various applications (e.g., contrast agents for cell imaging and therapeutics for treating cancer).Thus far, the integration of nanomaterials with biology has led to the development of diagnostic devices, contrast agents, analytical tools, physical therapy applications, and drug delivery vehicles.Abraxane, approved by the U.S. Food and Drug Administration (FDA) to treat breast cancer and non-small- cell lung cancer (NSCLC), is the nanoparticle albumin bound paclitaxel." } ]
