During year 2008–11, some infected leaves of eucalypt trees (Eucalyptus camaldulensis Dehnh.) having blight and spot symptoms were collected in Golestan province (N Iran). The necrotic spots were appeared on both surfaces of the leaves and were circular to irregular, single to confluent, medium brown to light brown with red brown margin (Fig. 1A & B). In some cases, young leaves have been sever...

In Stage 1 of 4 experiments in which rats completed a water-maze blocking procedure, experimental groups were trained to use a predictive beacon (hanging above, connected to, or displaced from the platform) to find a submerged escape platform in the presence of predictive or irrelevant background cues and in the presence or absence of irrelevant landmarks. In Stage 2, a fixed beacon, landmarks,...

Partial migration, in which some individuals of a population migrate while other individuals remain resident, is generally associated with ontogenetic shifts to better feeding areas or as a response to environmental instability, but its underlying mechanisms remain relatively unknown. Brown trout (Salmo trutta) exhibit partial migration, with some individuals remaining in freshwater (freshwater...

Statistical parsers trained and tested on the Penn Wall Street Journal (WSJ) treebank have shown vast improvements over the last 10 years. Much of this improvement, however, is based upon an ever-increasing number of features to be trained on (typically) the WSJ treebank data. This has led to concern that such parsers may be too finely tuned to this corpus at the expense of portability to other...

Introduction. Cardiopulmonary resuscitation is influenced by the quality of basic life support (BLS). The primary objective of our study was to compare efficiency in the acquisition of BLS skills using conventional training and the 4-stage approach as a teaching method for BLS training. Methods. In a prospective, randomised, 2-parallel group study, 266 first year medical students were randomise...

The brown planthopper (Nilaparvata lugens Stal.) is one of the major insect pests of rice (Oryza sativa L.). Exploitation of Host Plant Resistance is a major component to manage this pest. The development of rice varieties that are resistant to the brown planthopper is an important objective in current breeding programmes. This study was undertaken to identify QTLs for BPH resistance from an el...

Teh ultrasound-assisted magnetic stirrer was used as an effective extraction technique for teh evaluation of total phenolic contents (TPC) and antioxidant potential of ten Pakistani brown rice cultivars. For this purpose, ultrasonic (240W frequency 50/60 Hertz) assisted magnetic stirrer coupled with three solvents methanol, ethanol, and isopropanol in pure and aqueous fractions (80:20) were...

Brown tumor is a giant cell lesion associated with hyperparathyroidism. It is a non-neoplastic condition and represents terminal stage of the remodeling process in hyperparathyroid state. We report a case of brown tumor with multiple lesions in craniofacial region associated with ectopic parathyroid adenoma revealed after acute L-thyroxine poisoning. This case report emphasizes on the need for ...
