Demonstration of receptor-mediated chemotaxis by human spermatozoa. A novel quantitative bioassay.
No full textA novel in vitro technique is described for measuring the chemotactic activity of soluble substances for human spermatozoa. This new bioassay has demonstrated that the synthetic chemotactic peptide N-formyl-Met-Leu-Phe elicits a potent, specific (i.e., receptor-mediated) chemotactic effect on human spermatozoa with an EC50 of 3.2 X 10(-10) M. Quantitative chemotactic studies on human spermatozoa with nine N-formylated-peptide analogs have shown a rank order of peptide potency indistinguishable (p less than 0.001) from that obtained in binding and chemotactic studies with rabbit neutrophils. The competitive antagonist Boc (t-butoxycarbonyl)-Phe-Leu-Phe-Leu-Phe, 10(-6) M, completely inhibited the chemotaxis elicited by f-Met-Leu-Phe, 10(-9) M, and was able to shift by one order of magnitude the molar concentration required by f-Met-Leu-Phe-Phe and f-Met-Leu-Phe to elicit the maximal response. The ability of N-formylated peptides to function as sperm chemoattractants reveals a high degree of correlation with binding, chemotaxis, and lysosomal enzyme release previously employed to define the neutrophil chemotactic receptor. This first unequivocal demonstration of substances having a receptor-mediated chemotactic effect for human male gametes suggests that human spermatozoa may indeed have the ability to respond chemotactically to appropriate environmental signals

Ruff\u27s Chapel United Methodist Church, Ridgeway
No full textRuff’s Chapel was the first Methodist Church built in Ridgeway. It was built by a prominent Ridgeway merchant, David H. Ruff, who is buried in the small cemetery surrounding the church. Built about 1870, Ruff’s Chapel is a single-story, rectangular frame building, sheathed in weatherboard, with a front gabled roof. There are two sets of double doors on the façade, topped by four-light transoms and simple entablatures supported on scroll brackets. The roof is covered with embossed metal shingles. The square open belfry has a metal covered bellcast hip roof with a ball finial. According to tradition, Mr. Ruff threw 60 silver dollars into the metal when the bell was cast, to give it a silvery tone. The bell was removed for safekeeping after an attempt was made to steal it.

No full text(1948-2018) Donald Mitchell Crawford, Sr. (“DC”), musician, author, and educator, was born on May 24, 1948, and was a lifelong resident of Birmingham, AL. His father and mother owned and operated “C & S Charter Tours Bus Company,” the first black-owned bus company in the state of Alabama. Crawford was a 1966 graduate of Western Olin High School in Birmingham, AL. Crawford was an outstanding drum major, playing first chair alto saxophone under the tutelage of the late Amos F. Gordon, Sr. After high school, he received a music scholarship to Alabama State University (ASU) where he earned both his Bachelor’s and Master’s Degrees in Music Education and was later inducted into the “School of Music Hall of Fame” at ASU. He was the youngest ever inducted into the Alabama Jazz Hall of Fame. He was a veteran of the U.S. Army and performed with the 291 st and 283rd Army Band in Fort Bennett, GA. DC was Band Director at Jackson Olin High School and taught in the Birmingham School System for over thirty-five years. His love for music and performing lead him after his retirement to serve as Band Director for Miles College.
Crawford is the author of “The Wheels of the Birmingham Civil Rights Movement.” This book chronicles the lives of his late father and mother, Worcy and Christine Pride Crawford, and the role he and the company played in the Birmingham Civil Rights Movement
