X-inactivation, also called lyonization, a process by which one of the two copies of the x chromosome present in female mammals is inactivated
In 1959 Susumu Ohno showed that the two X-chromosomes of mammals were different: one appeared like the autosomes; the other was condensed and heterochromatic.
With the inactivation of Dow AFB in 1968, most of the base was purchased by the city of Bangor and reopened the following year as Bangor International Airport.
In October 1979, in as part of the inactivation of Aerospace Defense Command, the USAF gained command responsibilities which shifted to Tactical Air Command (TAC) and a sub-organization equivalent to a numbered air force designated as Air Defense, Tactical Air Command (ADTAC).
With the inactivation of the 73rd Space Group and closure of RAF Edzell, Scotland, in October 1996, the 5th Space Surveillance Squadron, at RAF Feltwell, United Kingdom incorporated the LASS mission.
Until its inactivation in April 2006, the 20th Operational Weather Squadron was responsible for producing and disseminating mission planning and execution weather analyses, forecasts, and briefings for Air Force, Army, Navy, Marines, Guard, Reserve, USFK, PACOM, PACAF, USAPRAC, SOCPAC, and NAVPAC forces operating at 115 installations/sites over 5.2 million sq.mi.
Moved to Sioux City, Iowa in 1966 as part of an ADC reorganization and became responsible for air defense a large area of the upper Midwest after the inactivation of the Sioux City Air Defense Sector.
With the inactivation of SAC, the wing was reassigned to Air Mobility Command on 1 June 1992 and was inactivated on 1 October 1992 as part of the general drawdown of the USAF after the Cold War ended, its components subsequently merging with collocated 443d Airlift Wing at Altus to form the 97th Air Mobility Wing.
On 2 October 1981, Deputy Secretary of Defense Frank Carlucci III ordered the inactivation of the Titan II weapon system.
Inactivated in 1957 due to budget reductions Reactivated by Air Training Command as a navigator training squadron in 1972; inactivated with the closure of Mather AFB and the inactivation of its host unit in 1993.
ESMC and WSMC became respectively the 45th Space Wing and 30th Space Wing within two months of the Division's inactivation in 1991.
Binary ethylenimine, an inactivant used in the inactivation of the foot-and-mouth disease virus
In the 1940s and early 1950s, further studies showed inactivation of diverse bacteria, influenza virus, and Penicillium chrysogenum (previously P. notatum) mold fungus using various glycols, principally propylene glycol and triethylene glycol.
Deletion of a portion of the 3’ end of the EpCAM gene causes epigenetic inactivation of the MSH2 gene by hypermethylating the promoter region of the MSH2 gene.
The biology of HPV+ OPC is distinct of HPV- OPC with P53 degradation (inactivated by E6 instead of by genetic mutation), pRB pathway inactivation (by E7 instead of Cyclin D1 amplification), and P16 upregulation (over-expression of p16 instead of inactivation due to reduced negative feedback from pRB).
RNA interference, also called RNA inactivation, a system that regulates the activity of genes
•
Inactivated vaccine, a vaccine that consists of viruses which are grown in culture and then killed
At low nM concentrations, Leptomycin B blocks the nuclear export of many proteins including HIV-1 Rev, MAPK/ERK, and NF-κB/IκB, and it inhibits the inactivation of p53.
Excerpt from The Kinetics of the Reaction Inactivation of Tyrosinase during its Catalysis of the Aerobic Oxidation of Catechol
With the inactivation of the 12th Tactical Fighter Wing, the 6259th Air Base Squadron and 6259th USAF Dispensary were activated at Phu Cat AB on 18 November 1971 to administrate services provided to the Air Force personnel remaining at the base.
In all cases, the disease is idiopathic, but is thought to involve inactivation of tumor suppressor genes (Menin gene in MEN1), or involve gain of function mutations (RET proto-oncogene MEN 2a).
Xenobiotic-metabolizing enzymes in the olfactory epithelium have been suggested to catalyze inactivation and facilitate elimination of odorants.
The most important genetic alteration associated with poor prognosis in uveal melanoma is inactivation of BAP1, which most often occurs through mutation of one allele and subsequent loss of an entire copy of Chromosome 3 (Monosomy 3) to unmask the mutant copy.
