TL;DR: Four humid grassland communities at three differ- ent locations in Meghalava show a clear seasonality, albeit with different patterns, with a maximum in density and basal cover in August and the differences in structure and seasonality are discussed in terms of different levels of stress.
Abstract: Four humid grassland communities at three differ- ent locations in Meghalava. India were analysed during 1988 and 1989 for species and life-form composition, diversity and dominance in relation to altitude, soil and prevailing distur- bances. Due to the adverse interactive influences of exception- ally high annual rainfall (> 10 000 mm), topography and human interference on soil fertility, the grassland at Cherrapunji, at 1300 m altitude, had a low species diversity (H' = 1.74) and was dominated by three perennial grass species. Similar grass- lands, at both higher and lower altitudes on fertile soil and with lower rainfall (ca. 2000 mm), showed higher diversity values (H' = 2.28 at Burnihat and 2.31 at Upper Shillong). The proportion of perennial species and chamaephytes increased with elevation. At the high altitude site a grassland under short- term protection from fires and grazing had a higher species richness, density and basal cover than an unprotected grass- land. All grasslands show a clear seasonality, albeit with different patterns, with a maximum in density and basal cover in August. The differences in structure and seasonality are discussed in terms of different levels of stress.

TL;DR: During tumor regression, ascites fluid volume decreases sharply and there is an increase in carbohydrates and decrease in protein contents in the ascites supernatant after cisplatin treatment in vivo.
Abstract: Cisplatin treatment brings about complete regression of ascites Dalton's lymphoma in mice. In the present study various steps involved during the tumor regression are examined using some biochemical and morphological parameters. During tumor regression, ascites fluid volume decreases sharply and there is an increase in carbohydrates and decrease in protein contents in the ascites supernatant after cisplatin treatment in vivo. Cisplatin treatment brings about definite changes in the arrangement/movement of surface membrane ruffles/blebs of tumor cells and causes infiltration of leukocytes (neutrophils, monocytes, lymphocytes) towards tumor cells. Membrane vesicles and vacuoles are also formed before the disintegration and lysis of tumor cells.

TL;DR: In this article, a detailed investigation of the dynamical behavior of mimetic gravity with a general potential for the mimetic scalar field is presented, which can successfully describe the thermal history of the universe, namely the successive sequence of radiation, matter, and dark energy eras.
Abstract: We present a detailed investigation of the dynamical behavior of mimetic gravity with a general potential for the mimetic scalar field. Performing a phase-space and stability analysis, we show that the scenario at hand can successfully describe the thermal history of the universe, namely the successive sequence of radiation, matter, and dark-energy eras. Additionally, at late times the universe can either approach a de Sitter solution, or a scaling accelerated attractor where the dark-matter and dark-energy density parameters are of the same order, thus offering an alleviation of the cosmic coincidence problem. Applying our general analysis to various specific potential choices, including the power-law and the exponential ones, we show that mimetic gravity can be brought into good agreement with the observed behavior of the universe. Moreover, with an inverse square potential we find that mimetic gravity offers an appealing unified cosmological scenario where both dark energy and dark matter are characterized by a single scalar field, and where the cosmic coincidence problem is alleviated.
