Free radicals play an important role in stomach ulcer formation. The present investigation validates the anti ulcer activity of hesperidin, isolated from Citrus sinensis (L.) Osbeck, Rutaceae, through the assessment of its antioxidant potential over stomach mucosal tissue by histological examination. Hesperidin was isolated from the dried peel of C. sinensis, and authenticated by TLC, IR and HP...

in recent years, anthracnose disease of citrus has caused and contiunes to cause heavy losses to some citrus commercial tree varieties in mazandaran province. this disease is deeply spread out in the citrus orchards of the province. in order to isolate and identify the causal agent or agents of the disease, random sampling was done from infected trees during 2004-2005. in lab, samples were cult...

Cellulase activity increased in separation-zone tissues 1 day after "Valencia" orange (Citrus sinensis [L.] Osbeck) was treated with 20 micrograms per milliliter cycloheximide. Exocellulase was detected only in the separation zones of treated fruit, whereas endocellulase was present in zones from both treated and control fruit. Endocellulase activity in separation-zone tissue of treated fruit w...

Background Dengue fever is a serious public health issue in Pakistan for many years. Globally plants have been reported to contain compounds with insecticidal properties. These properties have been demonstrated more recently on the larval stages of mosquitoes. Therefore, Citrus cultivar seeds were evaluated for larvicidal potential against the primary dengue vector Aedes aegypti. Methods Extr...

The vine mealybug, Planococcus ficus (Signoret) (Hemiptera: Pseudococcidae), is a pest in grape vine growing areas worldwide. The essential oils from the following aromatic plants were tested for their insecticidal activity against P. ficus: peppermint, Mentha piperita L. (Lamiales: Lamiaceae), thyme-leaved savory, Satureja thymbra L., lavender, Lavandula angustifolia Mill, and basil, Ocimum ba...

BACKGROUND Recently, there has been an increased interest in the effects of essential oils on athletic performances and other physiological effects. This study aimed to assess the effects of Citrus sinensis flower and Mentha spicata leaves essential oils inhalation in two different groups of athlete male students on their exercise performance and lung function. METHODS Twenty physical educati...

The present study observed the resistance to reinfection with Clonorchis sinensis in various experimental animals including mice, guinea pigs, rabbits, and dogs, as well as rats and hamsters. The resistance rates to reinfection in rats, mice, hamsters, guinea pigs, rabbits, and dogs were 79.7%, 58.0%, -12.6%, 54.8%, 62.6%, and 6.0%, respectively. Worms recovered from reinfected rats and mice we...

Genome wide selection (GWS) is essential for the genetic improvement of perennial species such as Citrus because of its ability to increase gain per unit time and to enable the efficient selection of characteristics with low heritability. This study assessed GWS efficiency in a population of Citrus and compared it with selection based on phenotypic data. A total of 180 individual trees from a c...

The polyamines (PA) putrescine (Put), spermidine (Spd), and spermine (Spm) were measured during 3 weeks exposure to cold hardening (15.6 degrees C day and 4.4 degrees C night) and nonhardening (32.2 degrees C day and 21.1 degrees C night) temperature regimes in three citrus cultivars: sour orange (SO) (Citrus aurantium L.), ;valencia' (VAL) (Citrus sinensis L. Osbeck), and rough lemon (RL) (Cit...

ABSTRACT Citriculture is a growing industry in Pará state, Brazil, but information regarding fruit flies and their associated parasitoids this region lacking. To address gap knowledge, we collected oranges (Citrus sinensis), lime (C. common sweet limes limettioides), citrons medica) mandarins reticulata). We recorded field infestation by Anastrepha obliqua C. sinensis under natural conditions f...
