Smilin\u27 Through

VERSE 1There’s a little brown road windin’ over the hillTo a little white cot by the sea;There’s a little green gateAt whose trellis I wait,While two eyes o’ blueCome smilin’ throughAt me! VERSE 2There’s a gray lock or two in the brown of the hair,There’s some silver in mine, too, I see;But in all the long yearsWhen the clouds brought their tears,Those two eyes o’ blueKept smilin’ throughAt me! VERSE 3And if ever I’m left in this world all alone,I shall wait for my call patiently;For if Heaven be kind,I shall wake there to findThose two eyes o’ blueStill smilin’ throughAt me

Sing Along!

School and Community Version1. As down the road of life we goTo seek our Promised Land,We\u27ll often find our progress slowAnd need a helping hand.So day by day and mile on mile,However rough and long,Let\u27s greet each other with a smileand sing some cheering song! REFRAINSing along! Oh, sing along!At work or while at play;If skies be gray and dull the day,Just sing along the way!Sing Along! Oh, sing along!And make the sad heart gay,You\u27ll always find the sunshine ifYou sing along the way! 2. If ever we grow tired and wornAnd skies above seem grey,If all the burdens we have borneGrow harder ev\u27ry day,Perhaps some old familiar strainThat we\u27ve forgotten long,Will bring the sunshine back again,So, cheer up with a song! Ballad Version1. There\u27s sunshine in your smile, dear heart,The blue sky\u27s in your eyes;I\u27m waiting all the while, dear heart,For some new sweet surprise!There\u27s music in your voice whene\u27erYou tell me of your love;You seem to sing along through lifeLike skylark far above! REFRAINSing along! Oh, sing along!Just sing along the way!If skies be gray and dull the day,Just sing along, you say!Sing along! Oh, sing along!And make the sad heart gay,You\u27ll always find the sunshine ifYou sing along the way! 2. We\u27ve been together, you and I,For many gladsome years;We\u27ve seen the rainbow in the skyA-shining through our tears.Each other\u27s joys and sorrows, too,We\u27ve shared, dear, right along,But through it all you never failedTo cheer me with your song

Smilin\u27 Through Song

There’s a little brown road windin’ over the hillTo a little white cot by the sea;There’s a little green gate at whose trellis I wait,While two eyes o’ blue come smilin’ through at me!There’s a gray lock or two in the brown of the hair,There’s some silver in mine, too, I see;But in all the long years when the clouds brought their tears,Those two eyes o’ blue kept smiling; through at me

Combustion-Derived Ultrafine Particles Transport Organic Toxicants to Target Respiratory Cells

Epidemiologic evidence supports associations between inhalation of fine and ultrafine ambient particulate matter [aerodynamic diameter ≤ 2.5 μm (PM(2.5))] and increases in cardiovascular/respiratory morbidity and mortality. Less attention has been paid to how the physical and chemical characteristics of these particles may influence their interactions with target cells. Butadiene soot (BDS), produced during combustion of the high-volume petrochemical 1,3-butadiene, is rich in polynuclear aromatic hydrocarbons (PAHs), including known carcinogens. We conducted experiments to characterize BDS with respect to particle size distribution, assembly, PAH composition, elemental content, and interaction with respiratory epithelial cells. Freshly generated, intact BDS is primarily (> 90%) PAH-rich, metals-poor (nickel, chromium, and vanadium concentrations all < 1 ppm) PM(2.5), composed of uniformly sized, solid spheres (30–50 nm) in aggregated form. Cells of a human bronchial epithelial cell line (BEAS-2B) exhibit sequential fluorescent responses—a relatively rapid (~ 30 min), bright but diffuse fluorescence followed by the slower (2–4 hr) appearance of punctate cytoplasmic fluorescence—after BDS is added to medium overlying the cells. The fluorescence is associated with PAH localization in the cells. The ultrafine BDS particles move down through the medium to the cell membrane. Fluorescent PAHs are transferred from the particle surface to the cell membrane, cross the membrane into the cytosol, and appear to accumulate in lipid vesicles. There is no evidence that BDS particles pass into the cells. The results demonstrate that uptake of airborne ultrafine particles by target cells is not necessary for transfer of toxicants from the particles to the cells
