https://www.selleckchem.com/products/tacrine-hcl.html The current research work was aimed to determine the morphological variation in the seeds of subfamilies Caesalpinioideae, Mimosoideae, and Papilionoideae using scanning electron microscope to investigate the different seed features including; Seed length, width, weight, hilum shape, position, fracture line pattern, pleurogram shape, texture crudeness, ornamentation wall, and surface ornamentation. A total of 12 species were collected. The study reveals that the seed types alters from psilate to rugose, pleurogram shape from lunar to U shape, hilum shape from elliptical to depressed, hilum position from terminal to subterminal, fracture line pattern from reticulate irregular ridges to psilate with regular ridges, texture crudeness from fine to coarse, surface ornamentation from reticulate to psilate, and ornamentation wall also varies from thin to thick. In all the studied species, it was found that seed surface was brown in color except in Senna alata, in which seed surface was black. Regarding the seed size, it was found that the smallest seed was observed for Sesbania sesban, while the largest seed was observed for Pongamia pinnata. The present research article indicates the taxonomic significance of seed morphology in the subfamilies Caesalpinioideae, Mimosaceae, and Papilionoideae. The study purpose was to investigate effects of a cognitive rehabilitation programme on cognitive function, self-management and quality of life in patients with chronic obstructive pulmonary disease. Cognitive impairment is frequently observed in chronic obstructive pulmonary disease patients, and it interferes with many aspects of self-management, which is fundamental to disease management and quality of life. The design is quasi-experimental. Data collection was performed between June 2018 and March 2019. Study participants were 60 in- or out-patients with chronic obstructive pulmonary disease.
