Background Systemic sclerosis (SSc, scleroderma) is a systemic autoimmune connective tissue disease (CTD). Disease subsetting specific to the extent of skin subdivides SSc into three following main subtypes: (1) limited cutaneous (lcSSc); (2) diffuse (dcSSc) and (3) sine scleroderma (ssSSc). Any subgroup can also have features one or more other CTDs [1]. When patient has any two CTDs, this sati...

THE SCIENTIFIC BASIS OF THE ILLINOI,S SYSTEM OF PERMANENT SOIL FERTILITY' IT is practically impossible to cover, in an adequate way, the scientific principles underlying the Illinois system of permanent soil fertility in the brief space of time allotted me on the p...

We investigate the symmetric and anti-symmetric spin-orbit forces (SLS and ALS) of the effective ΛN interaction derived from a quark cluster model with the instantoninduced interaction (I I I), which can reproduce the observed YN cross sections as well as the observed NN scattering data. It is found that coupling to the ΣN channel enhances ΛN ALS, and therefore that the cancellation between SLS...

Saliva constitutes an important role in maintaining the health of the oral cavity. It helps in lubrication, mastication, and has effective antimicrobial action. In prosthodontics, saliva plays a main role in retention of the denture. Hyposalivation is a main complication in diabetes, radiotherapy, chemotherapy, sjogren syndrome, certain systemic conditions and patients with maxillofacial defect...
