in order to develop a high yielding rice cultivar with optimum cooking quality, a cross was conducted between two rice cultivars khazar, high yielding and resistant to blast disease and daylamani tarom, with good cooking quality in 1990. forty pure lines were selected and compared for high grain yield in 1996. ten selected lines together with two check cultivars dasht and onda were tested in ad...

abstract sheath blight is an important rice disease in the mazandaran province of iran. biological control of this disease as alternative of chemical control with propiconazol (tilt) fungicide, examined with 3 biological products, trichodermin ab, trichodermin b and subtilin produced in iran. at first in the laboratory, fungi and bacterium isolated and purified from these products, and their ab...

tumors that originate from the nerve sheath comprise diverse groups -perineuroma, neurofibroma and schwannoma. the epithelioid variant of these tumors is uncommon and mostly seen in malignant counterparts. although this type of morphology is well recognized in peripheral nerve sheath tumors, its presence in the central nerves is rarely reported. very few cases of nerve sheath tumors have been r...

Sheath blight disease (ShB), caused by the fungus Rhizoctonia solani Kühn, is one of the most destructive diseases of rice (Oryza sativa L.), causing substantial yield loss in rice. In the present study, a novel rice chitinase gene, LOC_Os11g47510 was cloned from QTL region of R. solani tolerant rice line Tetep and used for functional validation by genetic transformation of ShB susceptible japo...

Background: Trigger finger is characterized by the inability to smoothly flex and extend the digit. Corticosteroids are an accepted non-surgical treatment option and can be delivered via two techniques. While the palmar approach is more commonly used, some have suggested that the mid-axial approach may be less painful for patients and yield higher intrasheath injection rates. The purpose of thi...

The plastic deformation and interface micro annulus of oil-well cement during acid fracturing are key reasons for the failure wellbore seal sustained casing pressure. However, most existing research ignores influence cooling effect fracturing, owing to which, design conditions in theoretical analysis may be inconsistent with those actual wellbore, calculation results biased. In this study, a no...

Sheath blight is considered the most significant disease of rice and causes enormous yield losses over the world. Breeding for resistant varieties is the only viable option to combat the disease efficiently. Seventeen diverged rice genotypes along with 17 QTL-linked SSR markers were evaluated under greenhouse conditions. Pearson's correlation showed only the flag leaf angle had a significant co...

Introduction Leaf of areca tree (Areca catechu L.) is a hard material (good tensile strength), slow in biodegradation and has low calorific value. About 1000 million leaf sheaths (2,33,000 tonnes) are available annually in India alone. Areca leaf sheath (cellulose, 43%) by digestion using sulphite process at 162°C for 3.5 h gives a pulp (yield, 36-40%), which in admixture with other pulp can be...

Around one century ago, a rice disease characterized mainly by rotting of sheaths was reported in Taiwan. The causal agent was identified as Acrocylindrium oryzae, later known as Sarocladium oryzae. Since then it has become clear that various other organisms can cause similar disease symptoms, including Fusarium sp. and fluorescent pseudomonads. These organisms have in common that they produce ...

the musculoskeletal extrapulmonary tuberculosis is uncommon, the upper extremity tuberculosis is not common and the mycobacterial involvement of skin of hands and synovial sheath of tendons is rare. this prospective observational study was undertaken between august  2014 and december 2015 in a tertiary referral hospital. patients attending with suspected primary tuberculosis of soft tissue of t...
