ABSTRACT Dental caries is a highly prevalent multifactorial disease and is a major public health problem. A goal of modern dentistry is to manage enamel white spot lesions noninvasively and effectively an attempt to prevent disease progression and improve esthetics, strength and function. The progression of caries has been tried to be curbed at initial stage only but for that only use of fluoride application was suggested but with recent developments in dental materials other remineralization options as well as noninvasive masking procedure can be performed to attain best result.

Molecular interaction between shrimp receptor protein PmCBP (Chitin binding protein of Peneaus monodon) and viral envelop protein VP24 is obligatory for binding of the White Spot Syndrome Virus to the shrimp digestive tract, and failure of this anchoring leads to an ineffectual infection. This is a first study that throws light on the molecular interaction of PmCBP-VP24 complex and provides important clues for initial steps of ingression of the virus into shrimps.

Abstract:
Maize white spot (MWS), caused by the bacterium Pantoea ananatis, is a serious disease that significantly impacts maize production and productivity. In recent years, outbreaks of white spot disease have resulted in substantial maize yield losses in southwest China. Researchers from various countries worldwide have conducted extensive research on this pathogen, including its isolation and identification, the localization of resistance genes, transmission pathways, as well as potential control measures. However, the information related to this disease remains fragmented, and standardized prevent

Abstract Reaction of 43 cultivars in three crapemyrtle taxa (Lagerstroemia indica, L. indica x fauriei and L. fauriei) to powdery mildew (Erysiphe lagerstroemia) and Cercospora leaf spot (Cercospora lythracearum) was evaluated for three years in a simulated landscape planting in Auburn, AL. Overall, the incidence of powdery mildew was lower on L. indica x fauriei and L. fauriei than on L. indica. In two of three years, Cercospora leaf spot severity was similar among all cultivars of L. indica and L. indica x fauriei, while the single selection of L. fauriei ‘Fantasy’ proved highly resistant to

Abstract:
Luobuma (Apocynum venetum and Poacynum hendersonni) is widely cultivated for environmental conservation, medicinal purposes and the textile industry. In 2018, a severe leaf spot disease that attacked the leaves of Luobuma was observed in plants cultivated in Yuzhong County, Gansu Province, China. Symptoms of the disease appeared as white or off-white spots surrounded by brown margins on the leaves of A. venetum. The spots expanded and covered a large area of the leaf, presenting as “cankers” with progression of the disease, leading to leaf death. The initial symptoms of the disease on P. hende

The plant material used was obtained from a program of recurrent selection, which was started by crossing seven lines with carioca grain type with ten sources of resistance to angular leaf spot according to the partial diallel scheme. To evaluate the resistance to white mold, it was verified the reaction of 17 parents plus 35 selected progenies, to oxalic acid. Huge heterogeneity among the parents was observed, showi

A plant's nutritional balance can influence its resistance to diseases. In order to evaluate the effect of increasing doses of N and K on the yield and severity of the mayze white spot, two experiments were installed in the field, one in the city of Ijaci, Minas Gerais, and the other in the city of Sete Lagoas, Minas Gerais. The experimental delimitation was in randomized blocks with 5 x 5 factorial analysis of variance, and four repetitions. The treatments consisted of five doses of N (20; 40; 80; 150; 190 Kg ha-1of N in the experiments 1 and 2) and five doses of K (15; 30; 60; 120; 180 Kg ha

 Lumpy jaw is a deer health problem that all deer farmers eventually face. It gets its name from the swollen jaws or cheeks and necrotic lesions it causes in and around the jaw bones of animals including white-tailed deer. The disease is considered a significant problem for deer farms in North America, where it is one of the most important production-limiting diseases and causes high rates of mortality in fawns.

Viral DNA shedding was detected within 6 h of disease onset. This shedding intensified over time, reaching a peak within 12 h of the time of death.
