In this study, seventy 1-d-old male broiler chicks were randomly allocated to 10 groups to investigate the effect of cold stress on the messenger RNA (mRNA) levels of corticotrophin-releasing hormone (CRH) and thyrotropin-releasing hormone (TRH) in hypothalami. The chicks were maintained at 30 +/- 2 degrees C temperature and given free access to standard chow and water. Until 15 d old, the 6 tr...

Bermudagrass is widely utilized in parks, lawns, and golf courses. However, cold is a key factor limiting resource use in bermudagrass. Therefore, it is meaningful to study the mechanism of bermudagrass response to cold. Nitric oxide (NO) is a crucial signal molecule with multiple biological functions. Thus, the objective of this study was to investigate whether NO play roles in bermudagrass re...

In this work, the influence of crystallographic texture on mechanical properties was investigated by X-ray diffraction in the superelastic Ti-24Nb-4Zr-8Sn alloy. Different textures were obtained by changing the cold rolling reduction rate and the following thermal treatment (solution treatment or flash thermal treatment). The tensile tests performed show that Young’s modulus, elongation at rupt...

To prevent leaf senescence of young transplants or excised shoots during storage under dark and cold conditions, the cytokinin biosynthetic gene isopentenyl transferase (ipt) was placed under the control of a cold-inducible promoter cor15a from Arabidopsis thaliana and introduced into Petunia x hybrida 'Marco Polo Odyssey' and Dendranthema x grandiflorum (chrysanthemum) 'Iridon'. Transgenic cor...

Elevated circulating angiotensin (Ang) II levels, dietary sodium, and sympathetic stimulation are recurrent themes of hypertension research, but their in vivo interaction in physiologically meaningful doses has not been adequately investigated. In this study, the interaction of a subpressor dose of Ang II (50 ng. kg(-1). min(-1) SC), 2% NaCl diet, and sympathetic stimulation in the form of over...

Effects of cold oxygen plasma treatment on activating the surface of poplar veneers and improving its wettability were investigated. The veneers were treated with cold oxygen plasma for 1, 3, 5, 7, and 9 min, and aged in air for 1, 3, 7, 14, 21, and 28 days. The dynamic adhesive wettability of veneers was assessed using the contact angle, K-value analysis, and surface free energy. The shear str...

MYB transcription factors play central roles in plant responses to abiotic stresses. How stress affects development is poorly understood. Here, we show that OsMYB3R-2 functions in both stress and developmental processes in rice (Oryza sativa). Transgenic plants overexpressing OsMYB3R-2 exhibited enhanced cold tolerance. Cold treatment greatly induced the expression of OsMYB3R-2, which encodes a...

Abstract: Cold injuries are very common among the troops deployed in high altitude regions. Now days, it is also seen among the civilian populations like mountaineers and winter sportspersons. There is no definitive treatment protocol available for this entity. In this study, 234 patients of various degrees of cold injuries were treated with a standard protocol of multidrug therapy with a view ...
