Photosynthetic activity and organization of chlorophyll(Chl)-protein complexes in a temperature sensitive mutant of Chlorella pyrenoidosa have been investigated. The mutant is practically indistinguishable from wild type cells when grown at 25 C. However, mutant cells grown at 33 C do not synthesize Chl and lose their ability to evolve O(2). O(2) evolution and Chl synthesis are restored upon in...
thesis were investigated in two clonal genotypes of Acer rubrum L., originally collected from the thermally contrasting habitats of Florida and Minnesota, USA, and known in the horticultural trade for sensitivity and insensitivity to heat, respectively. Under both common garden and warm greenhouse conditions (day/night temperature of 33/25 °C), the Florida genotype exhibited more growth than th...
Effects of moderate heat on growth and photosynthesis were investigated in two clonal genotypes of Acer rubrum L., originally collected from the thermally contrasting habitats of Florida and Minnesota, USA, and known in the horticultural trade for sensitivity and insensitivity to heat, respectively. Under both common garden and warm greenhouse conditions (day/night temperature of 33/25 degrees ...

development, reproduction and life table parameters of tetranychus urticae koch were determined on leaves of peach (g. h. hale cultivar) at different temperatures, ranging from 13 to 33°c under laboratory conditions. no development was observed at 13°c. egg-to-adult developmental time decreased gradually from 17 to 27°c and increased at higher temperatures (27 to 33°c). an average of 136.43 deg...
The central mechanism controlling food intake in response to the change in environmental temperature has been little examined. The GABA agonist, muscimol, was injected into the lateral ventricle of rats which were acclimated to temperate (26 degrees C) and hot (33 degrees C) environments. Muscimol obviously stimulated the feeding behavior of rats in both environments. However, when muscimol was...
زمینه مطالعه: در سال‌های اخیر، اختلال در متابولیسم لیپیدها، به شکل قابل توجهی، در جمعیت حیوانات خانگی افزایش یافته است. هیپرلیپیدمی، یک علامت شایع از بروز چاقی در سگ‌ها است که به‌صورت هیپرکلسترولمی یا هیپرتری‌گلیسریدمی مشخص می‌گردد. هدف: هدف از انجام تحقیق حاضر، تعیین اثر چاقی بر تغییرات پروفایل‌های لیپیدی خون (مشتمل بر تری‌گلیسرید، کلسترول تام، HDL-C و LDL-C) و مقایسه شاخص‌های تعیین کنننده چاق...
A heat-sensitive (hs, arrested at 39.5°C, multiplying at 33°C) and a cold-sensitive (cs, arrested at 33°C, multiplying at 39.5°C) cell cycle variant were isolated from an undifferentiated P-815 murine mastocytoma line. At the respective nonpermissive temperature, both the hs and the cs variant cells were reversibly arrested with a DNA content, typical of GI phase. The cells of two cs variant su...
INTRODUCTION The optimal temperature during targeted temperature management (TTM) for comatose patients resuscitated from out-of-hospital cardiac arrest is unknown. It has been hypothesized that patients with long no-flow times, for example those without bystander CPR would have the most to gain from temperature management at lower temperatures. METHODS We analysed data from an international ...
