Three factors that directly affect the water inputs in cropping systems are root architecture, length of the growing season, and stomatal conductance to water vapor (). Deeper-rooted cultivars will perform better under water-limited conditions because they can access water stored deeper in the soil profile. Reduced limits transpiration rate () and thus throughout the vegetative phase conserves water that may be used during grain filling in water-limited environments. Additionally, growing early-maturing varieties in regions that rely on soil-stored water is a key water management strategy...

Glaucoma is a neurodegenerative disease characterized by the progressive loss of retinal ganglion cells and optic nerve axons. According to its anatomical features, glaucoma is mainly subdivided into primary open-angle glaucoma (POAG) and primary angle-closure glaucoma (PACG). Exfoliation syndrome (XFS) and glaucoma (XFG) are characterized by the accumulation of extracellular materials in ocular tissues, particularly the lens surface and pupillary border. In addition to the two major forms of glaucoma, XFG is the most common cause of secondary open-angle glaucoma...

Aliasghar Sepehri, Troy D Loeffler, Bin Chen
The Jacobian-Gaussian method, which has been recently developed for generating bending angle trials, is extended to the conformational sampling of inner segments of a long chain or a cyclic molecule where regular configurational-bias Monte Carlo was found to be very inefficient or simply incapable (i.e., for the cyclic case). For these molecules, a new conformational move would be required where one interior section is relocated while the rest of the molecule, before and after this section, is fixed. Techniques have been developed to extend the regular configurational-bias Monte Carlo to such a fixed-endpoints case by introducing a biasing probability function...

Most of the rare bilateral acute angle closure (AAC) cases are precipitated by systemic factors, such as drug intake, snake bite or general anaesthesia. We present a case of simultaneous bilateral AAC in a middle-aged male, precipitated by the use of medication for flu, containing an alpha-1 adrenergic receptor agonist and an anticholinergic agent. In our case, axial length was shorter, anterior chamber depth was narrower, and the lens was thicker than normal, including the patient within the risk group for AAC...

Atrial septal defect (ASD) constitutes 30-40% of all congenital heart diseases in adults. The most common complications in the treatment of ASD are embolization of the device and thrombosis formation. In this research, an occluding patch was developed for ASD treatment using a well-known textile technology called electrospinning. For the first time, a cardiovascular occluding patch was fabricated using medical grade polyurethane (PU) loaded with bioactive agents namely chitosan nanoparticles (Cn) and collagen (Co) which is then coated with heparin (Hp)...

Along with function, aesthetics plays an important role in treating partially or completely edentulous patients. Ageing, trauma, tooth loss and neuromuscular disorders have a high impact on tonicity of facial musculature, elasticity of skin as well as function of muscles. Patients affected with Bell's palsy face functional, aesthetic as well as psychological impairment. Common problems are the partial closure of upper eyelid, sagging of lower eyelid and drooping of angle of mouth leading to facial asymmetry, along with difficulty in eating, drinking and speaking...
