Defining demographic and ecological threshold of population persistence can assist in informing conservation management. We undertook such analyses for the Indo-Pacific humpback dolphin (Sousa chinensis) in the Pearl River Delta (PRD) region, southeast China. We use adult survival estimates for assessments of population status and annual rate of change. Our estimates indicate that, given a stat...
The in vitro effects of Concanavalin A (Con A) and prednisolone (PRD) on the cytotoxic functions of lymphocytes and the generation of lymphokine-activated killer (LAK) cells were investigated. Con A at concentrations ranging from 1 to 40 micrograms/ml did not significantly affect the cytotoxicity of LAK cells when added directly to the effector and target cell mixture in a 4-hr 51Cr release ass...
Peroxiredoxin 6 (Prd x 6) is a novel peroxidase enzyme that is expressed at a high level in the lung. We tested the hypothesis that transgenic (Tg) mice overexpressing Prd x 6 would exhibit increased resistance to hyperoxia-induced lung injury. Wild-type and Tg mice were exposed to 100% O(2) and evaluated for survival, lung histopathology, total protein, and nucleated cells in bronchoalveolar l...
Recent electrophysiological and behavioral studies have found similarities in the neurology of pursuit and saccadic eye movements. In a previous study on eye movements using closely matched paradigms for pursuit and saccades, we revealed that both exhibit bimodal distributions of latency to predictable (PRD) and randomized (RND) stimuli; however, the latency to each type of stimulus was differe...
Polychlorinated biphenyls (PCBs) contamination in tropical and sub-tropical areas and the associated risks have attracted great concern. A total of 69 samples representing five distinct land types were collected to assess PCB concentrations in the Pearl River Delta (PRD), South China, including spatial distributions in soils of the area, the probable anthropogenic sources, and related potential...
Sequence learning is common to all motor systems and is an essential aspect of human behavior necessary for the acquisition of motor skill. Many previous studies have demonstrated the ability to observe, store, and repeat sequences in a variety of modalities resulting in reduced reaction time. Recently, it has been found that subjects can make predictive smooth eye movements to a sequence of di...
OBJECTIVE To prepare a website for families and health professionals containing up to date information about paediatric rheumatic diseases (PRD). METHODS Firstly, paediatric rheumatology centres and family self help associations were surveyed to characterise current clinical practice of physicians providing care for children with PRD, research activities, and training facilities of each centr...
در سال های اخیر استفاده از سیستم های کشت بدون خاک در گلخانه ها ی تولید سبزی در ایران گسترش زیادی یافته است. اغلب تولید کنندگان بدون توجه به نیاز آبی واقعی گیاه، محلول دهی به آن را انجام می دهند. از آنجایی که برخی بسترهای استفاده شده درگلخانه ها بیشتر از نوع بستر های مصنوعی است و اغلب بستر های استفاده شده ظرفیت نگهداری آب کمی دارند، احتمال هدر رفتن مقداری از محلول مصرفی یا وقوع تنش ...
The Preventive Restructuring Directive (PRD) has triggered a new era of regulatory competition. Member States are introducing laws aimed at making themselves the destination choice for corporate restructuring. However, PRD failed to provide clear answer some key issues: international jurisdiction, recognition and applicable law. This article analyses these questions in detail proposes answers.
partial rootzone drying (prd) is a new irrigation technique which improves water use efficiency without significant yield reduction in grape. to study the effects of partial rootzone drying and green pruning on yield and yield quality of thompson seedless grape a split plot experiment with randomized complete block design and three replications was conducted. the experiment was performed in tak...
