Some epidemiological studies suggest that increased consumption of anthocyanins is associated with lower risk of cardiovascular disease (CVD) and hypertension. Also, high consumption of anthocyanin-rich fruit, such as berries, is associated with a lower risk of developing type 2 diabetes (T2D). In this review, we briefly yet critically assess the available evidence in support of an anti-diabetic role of anthocyanins derived from berries, especially bilberry (Vaccinium myrtillus L., also known as European blueberry, whortleberry, huckleberry and blaeberry) and blueberry (Vaccinium corymbosum, native to the United States)...

The eastern cherry fruit fly, Rhagoletis cingulata Loew (Diptera: Tephritidae), is an economically important pest of cherries in North America. In 1983 it was first reported in Europe where it shares its ecological niche with the native European cherry fruit fly, Rhagoletis cerasi L. (Diptera: Tephritidae). Their coexistence in Europe led to the recent horizontal transmission of the Wolbachia strain wCer1 from R. cerasi to R. cingulata Horizontal Wolbachia transmission is mediated by either sharing of ecological niches or by interacting species such as parasitoids...

BACKGROUND AND AIMS: Cardiovascular benefits of fruits are attributed mainly to their (poly)phenolic constituents, especially anthocyanins. The main aim of our study is to compare effects of iridoids and anthocyanins from one fruit on diet-induced atherosclerosis. The cornelian cherry is a native or cultivated plant that grows in many European countries, used in cuisine and folk medicine. In our previous study, we showed its constituents and proved that oral administration of lyophilized fruits to hypercholesterolemic rabbits had preventive effects on atherosclerosis through the activation of PPARα expression...

Various plant species have long been used in traditional medicine worldwide to treat diabetes. Among the plant-based compounds with hypoglycemic properties, studies on insulin-like proteins isolated from leaves, fruits and seeds are rarely reported in the relevant literature. Our research group has been investigating the presence of insulin-like proteins in Moringa oleifera, a plant species native to India, and we have obtained a leaf protein isolate and semi-purified derived fractions, as well as a seed coat protein fraction (Mo-SC), with hypoglycemic activity in chemically induced diabetic mice that have increased tolerance to orally administered glucose...

A 9 yr old rat terrier presented with corneal ulceration and conjunctivitis that developed acutely after digging among dry leaves in wooded northern Arizona. Ophthalmic examination revealed multiple linear foreign bodies throughout the adnexal tissue and cornea of the left eye. Manual removal of material was unsuccessful. The palpebral conjunctiva required excision with tenotomy scissors to remove structures and allow corneal healing. Microscopic examination revealed structures believed to be setae from a Theraphosidae tarantula...

Pollinators provide an essential service to natural ecosystems and agriculture. In tomatoes flowers, anthers are poricidal, pollen may drop from their pore when flowers are shaken by the wind. However, bees that vibrate these anthers increase pollen load on the stigma and in fruit production. The present study aimed to identify the pollinator richness of tomato flowers and investigate their morphological and functional traits related to the plant-pollinator interaction in plantations of Central Brazil. The time of anthesis, flower duration, and the number and viability of pollen grains and ovules were recorded...

OBJECTIVE: Genetically tractable fruit flies have been used for decades to study seizure disorders. However, there is a paucity of data specifically correlating fly and human seizure phenotypes. We have previously shown that mutation of orthologous PRICKLE genes from flies to humans produce seizures. This study aimed to determine whether the prickle-mediated seizure phenotypes in flies closely parallel the epilepsy syndrome found in PRICKLE patients. METHODS: Virtually all fly seizure studies have relied upon characterizing seizures that are evoked...

Chilecomadia valdiviana (Philippi) (Lepidoptera: Cossidae) is an insect native to Chile. The larval stages feed on the wood of economically important fruit tree species such as apple, pear, olive, cherry, and avocado, and also on eucalyptus. This causes weakening and, in case of severe infestation, death of the tree. We report identification of the sex pheromone produced by females of this species. Hexane extracts of the abdominal glands of virgin females were analyzed by gas chromatography (GC) with electroantennographic detection, GC coupled with mass spectrometry, and GC coupled to infrared spectroscopy...
