BACKGROUND Lumbar disc disease (LDD), one of the most common conditions for which patients seek medical care, has been associated with sequence changes of the COL genes. COL1A1, however, has not been studied in young patients with LDD; COL1A1 polymorphisms have been associated with bone mineral density (BMD) in several populations and with LDD in older adults. OBJECTIVE To study COL1A1 polymo...

PTEN is one of the most frequently mutated tumor suppressor genes in human cancers. Germ line mutations of PTEN have been detected in three rare autosomal-dominant disorders. However, identical mutations in the PTEN gene may lead to different symptoms that have traditionally been described as different disorders, such as Cowden disease, Lhermitte-Duclos disease, and Bannayan-Zonana syndromes. T...

Long-distance dispersal (LDD) plays an important role in many population processes like colonization, range expansion, and epidemics. LDD of small particles like fungal spores is often a result of turbulent wind dispersal and is best described by functions with power-law behavior in the tails ("fat tailed"). The influence of fat-tailed LDD on population genetic structure is reported in this art...

AbstructA new extraction algorithm for the metallurgical channel length of conventional and LDD MOSFET’s is presented, which is based on the well-known resistance method with performing a special technique to eliminate the uncertainty of the channel length as well as to reduce the influence of the parasitic source/drain resistance on threshold-voltage determination. l n particular, the metallur...

In the sentence "The captain who the sailor greeted is tall," the connection between the relative pronoun and the object position of greeted represents a long-distance dependency (LDD), necessary for the interpretation of "the captain" as the individual being greeted. Whereas the lesion-based record shows preferential involvement of only the left inferior frontal (LIF) cortex, associated with B...

Estimating distances and rates of seed dispersal, especially long-distance dispersal (LDD), is critical for understanding the dynamics of patchily distributed populations and species' range shifts in response to environmental change. Daviesia triflora (Papilionaceae) is an ant-dispersed shrub. The ant Rhytidoponera violacea was recorded dispersing its seeds to a maximum distance of 4.7 m, and i...

Long-distance dispersal (LDD) includes events in which propagules arrive, but do not necessarily establish, at a site far removed from their origin. Although important in a variety of ecological contexts, the system-specific nature of LDD makes ‘‘far removed’’ difficult to quantify, partly, but not exclusively, because of inherent uncertainty typically involved with the highly stochastic LDD pr...

The performance and reliability of NMOSFET asymmetric lightly doped drain (LDD) devices (with no LDD on the source side) are compared with those of conventional LDD devices. At a fixed Vdd; asymmetric LDD devices exhibit higher Idsat and shorter hot-carrier lifetime. To maintain the same hot-carrier lifetime, asymmetric LDD devices must operate at lower Vdd while higher Idsat is retained. For t...
