In 1968 Shirley Chisholm became the first Black woman elected to the United States Congress. In 1972 she launched a campaign for the Democratic presidential nomination, breaking another political barrier.

PSGL is a rendering API available additionally to GCM and OpenGL for Sony's PlayStation 3. PSGL is based on OpenGL ES[1] and Nvidia's CG. A previous version of PSGL was available for the PlayStation 2 but was largely unused.
PSGL was meant to be a foundation for the future, beyond the PlayStation 3, but for the PlayStation 4 Sony introduced GNM and GNMX and also their custom shading language, PlayStation Shader Language (PSSL).[2]

Persatuan Sepakbola Gayo Lues, commonly known as PSGL Gayo Lues, is an Indonesian football club based in Gayo Lues Regency, Aceh. They played in the 2011–12 Premier Division, the second-tier league in Indonesia. However, now they play in the lowest tier Indonesian league, Liga 4.
Selectin P ligand, also known as SELPLG or CD162 (cluster of differentiation 162), is a human gene. SELPLG codes for PSGL-1, the high affinity counter-receptor for P-selectin on myeloid cells and stimulated T lymphocytes. As such, it plays a critical role in the tethering of these cells to activated platelets or endothelia expressing P-selectin. Naive and stimulated lymphocytes appear to use PSGL-1 for trafficking into and out of lymph nodes. The gene and protein structure of human PSGL-1 was first discovered in 1993 by Dianne Sako. The research team at Genetics Institute (GI) named the molecule PSGL-1 for "P-selectin glycoprotein ligand-1" although it was found to also bind the other two selectins types. In 1994, the GI team then led by Gray Shaw discovered that most of the binding activity of PSGL-1 was localized within its N-terminal 19 amino acids, including three sulfotyrosines (Tys) at positions 5, 7 and 10 and a critical O-linked glycan attached to the threonine at position 16 of the mature, fully processed PSGL-1 present on a cell's surface. They termed this the "anionic segment" of PSGL-1 in 1995 and then published the co-crystal structure of human PSGL-1's anionic segment bound to human P-selectin in 2000. The organization of the SELPLG gene closely resembles that of CD43 and the human platelet glycoprotein GpIb-alpha both of which have an intron in the 5-prime-noncoding region, a long second exon containing the complete coding region, and TATA-less promoters. P-selectin glycoprotein ligand-1 (PSGL-1) is a dimeric mucin-like glycoprotein found primarily on the surface of white blood cells. PSGL-1 can serve as a ligand for P-selectin (P stands for platelet), which is one of a family of selectins that includes E-selectin (endothelial) and L-selectin (leukocyte). Selectins are part of the broader family of cell adhesion molecules. PSGL-1 can bind to each of the three members of the family but binds best (with the highest affinity) to P-selectin.
The 2013 Liga Indonesia Premier Division season is the eighteenth edition of Liga Indonesia Premier Division since its establishment in 1994. The competition is managed by PT. Liga Indonesia (LI). This season is the second season of Liga Indonesia Premier Division organised by PT.Liga Indonesia without authorisation from PSSI as it has decided to appoint the new PT. Liga Prima Indonesia Sportindo (LPIS) to organise the competition. It is then recognised by PSSI breakaway leadership under La Nyalla Matalitti. The participant initially consists of 37 clubs, Included the four clubs that played last season at DU PT LPIS, PSIS Semarang, PSCS Cilacap, Persikabo Bogor and Persbul Buol, later added to 42 clubs, after 5 clubs, (Persipasi Bekasi, Persik Kediri, PS Madiun Putra, Persewangi Banyuwangi, and PPSM Sakti Magelang) come back from competition that held by PT. LPIS, and divided into five groups. The fixtures were released on 23 January 2013. The season kicked off on 27 January 2013 and the group stage is scheduled to conclude on 23 Juny 2013. On 1 February 2013, PT. Liga Indonesia received resignation PSGL Gayo Lues due to lack of sponsors to support their progress in the competition this season. On 6 February 2013, PT. Liga Indonesia disqualified PSAB Aceh Besar and Persipasi Bekasi due to administrative reason.
Before the 1921 destruction of Tulsa’s Greenwood District, Black residents had created a remarkable center of business and community life. The district included stores, professional offices, entertainment venues and homes owned by Black citizens. Understanding Greenwood means learning what was built—not only what was burned.
