Igbo culture

Igbo culture (Igbo: Ọmenala ndị Igbo) are the customs, practices and traditions of the Igbo people of southeastern Nigeria. It comprises archaic practices as well as new concepts added into the Igbo culture either by cultural evolution or by outside influence. These customs and traditions include the Igbo people's visual art, music and dance forms, as well as their attire, cuisine and language dialects. Because of their various subgroups, the variety of their culture is heightened further.

Music

The Igbo people have a melodic and symphonic musical style, which they designed from forged iron. Other instruments include opi, a wind instrument similar to the flute, igba, and ichaka.

Another popular musical form among Igbo people is highlife, which is a fusion of jazz and traditional music and widely popular in West Africa. The modern Igbo highlife is seen in the works of Prince Nico Mbarga Dr Sir Warrior, Oliver De Coque, Bright Chimezie, and Chief Osita Osadebe, who are the some of the greatest Igbo highlife musicians of the twentieth century. There are also other notable Igbo highlife artists, like the Mike Ejeagha, Paulson Kalu, Ali Chukwuma, Ozoemena Nwa Nsugbe.

SU-76

The SU-76 (Samokhodnaya Ustanovka 76) was a Soviet self-propelled gun used during and after World War II. The SU-76 was based on a lengthened and widened version of the T-70 light tank chassis. Its simple construction made it the second most produced Soviet armoured vehicle of World War II, after the T-34 tank.

Crews liked the vehicle for its simplicity, reliability, and ease of use. However, the steering was also sometimes regarded as cumbersome, leading crews to also refer to the vehicle as suka ("bitch") or Suchka ("little bitch"). It was also nicknamed Golozhopiy Ferdinand ("bare-arsed Ferdinand") due to its very light armor and somewhat similar silhouette, when compared to the Germans' heavy Ferdinand/Elefant casemate tank destroyer of some 65 tonnes in weight.

History

Design of the SU-76 began in November 1942, when the State Defense Committee ordered the construction of infantry support self-propelled guns armed with the ZiS-3 76.2 mm anti-tank gun and the M-30 122 mm howitzer. The T-70 chassis was chosen for mounting the ZiS-3 gun, and was lengthened, adding one road wheel per side, to facilitate better gun mounting. The vehicle was completely enclosed by armour.

OSU-6162

OSU-6162 (PNU-96391) is a compound which acts as a partial agonist at both dopamine D₂ receptors and 5-HT_2A receptors. It acts as a dopamine stabilizer in a similar manner to the closely related drug pridopidine, and has antipsychotic, anti-addictive and anti-Parkinsonian effects in animal studies. Both enantiomers show similar activity but with different ratios of effects, with the (S) enantiomer (–)-OSU-6162 that is more commonly used in research, having higher binding affinity to D₂ but is a weaker partial agonist at 5-HT_2A, while the (R) enantiomer (+)-OSU-6162 has higher efficacy at 5-HT_2A but lower D₂ affinity.

OSU-03012

OSU-03012 (AR-12) is a celecoxib derivative with anticancer and anti-microbial activity. Unlike celecoxib, OSU-03012 does not inhibit COX, but inhibits several other important enzymes instead which may be useful in the treatment of some forms of cancer, while also having antifungal activity via disruption of phosphoinositide-dependent kinase-1 activity. When combined with PDE5 inhibitors such as sildenafil or tadalafil, OSU-03012 was found to show enhanced anti-tumour,antibiotic and antiviral activity against a wide variety of organisms, with this activity thought to be mediated via inhibition of the chaperone protein BiP.

Orphan drug designation

The European Commission has designated AR-12 as an orphan drug for use in combination with other drugs for treatment of two infections diseases, cryptococcosis and tularaemia. AR-12 received an orphan drug designation in combination with the antifungal drug fluconazole for cryptococcosis of the brain. It also received this designation for tularaemia in combination with the antibacterial drug gentamicin.
