Water is a major limiting factor in world agriculture. In general, most crop plants are highly
sensitive to even a mild dehydration stress. There are however, a few genera of plants …

Plant cell walls, the major reservoir of fixed carbon in nature, have three major polymers:
cellulose (insoluble fibers of/3-1, 4-glucan), hemicellulose (noncellulosic polysaccharides …

Fibrillin microfibrils are extensible polymers that endow connective tissues with long-range
elasticity and have widespread distributions in both elastic and non-elastic tissues. They act …

Primary pulmonary hypertension (PPH), characterized by obstruction of pre-capillary
pulmonary arteries, leads to sustained elevation of pulmonary arterial pressure (mean> 25 …

The Ti content of biotite can serve as a geothermometer for graphitic, peraluminous
metapelites that contain ilmenite or rutile and have equilibrated at roughly 4-6 kbar. The …

Background Most patients with familial primary pulmonary hypertension have defects in the
gene for bone morphogenetic protein receptor II (BMPR2), a member of the transforming …

BACKGROUND Primary pulmonary hypertension (PPH), resulting from occlusion of small
pulmonary arteries, is a devastating condition. Mutations of the bone morphogenetic protein …

Background—Mutations in the type II receptor for bone morphogenetic protein (BMPR-II), a
receptor member of the transforming growth factor-β (TGF-β) superfamily, underlie many …

Primary pulmonary hypertension (PPH) is a potentially lethal disorder, because the
elevation of the pulmonary arterial pressure may result in right-heart failure. Histologically …

A core difficulty in developmental dyslexia is the accurate specification and neural
representation of speech. We argue that a likely perceptual cause of this difficulty is a deficit …
