Host plant and humidity effects on phytoseiid mite, Gynaeseius liturivorus (Acari: Phytoseiidae) egg hatchability.

Gynaeseius liturivorus (Ehara) (Acari: Phytoseiidae) is a promising biological control agent for tiny arthropod pests, including Thrips tabaci Lindeman (Thysanoptera: Thripidae) known as a major pest of Welsh onion. In fields during summer, G. liturivorus is observed on soybean, but not on Welsh onion, even when numerous T.

Milk basic protein supplementation enhances fracture healing in mice.

Objectives: There is an unmet need for agents that can stimulate bone healing. The goal of this study was to evaluate the effects of basic proteins from milk whey (milk basic protein [MBP]) on fracture healing in mice.

Methods: Closed tibial transverse fractures were generated in 6-wk-old male C3 H/HeJ mice given either tap water or MBP-supplemented water for 3, 7, 14, 28, and 56 d after fracture generation.

The role of cyclophilin D in interspecies differences in susceptibility to hepatotoxic drug-induced mitochondrial injury.

Test compound A ((5Z)-6-[(2R,3S)-3-({[(4-Chloro-2-methylphenyl)sulfonyl]amino}methyl) bicyclo[2.2.2]oct-2-yl]hex-5-enoic acid) was withdrawn from premarketing clinical trials due to severe liver injury.

Effect of allergen sensitization on external root resorption.

In orthodontic tooth movement (OTM), we should be concerned about external root resorption (ERR) as an undesirable iatrogenic problem, but its mechanisms are not fully understood. Since our previous epidemiologic studies found that patients with allergic diseases showed higher rates of ERR during orthodontic treatment, we explored the possible effect of allergic sensitization on ERR. In ovalbumin (OVA)-sensitized Brown-Norway rats, the amounts of ERR and OTM were greater than those in animals subjected to orthodontic force alone.

Synthesis and evaluation of γ-lactam analogs of PGE₂ as EP4 and EP2/EP4 agonists.

To identify topically effective EP4 agonists and EP2/EP4 dual agonists with excellent subtype selectivity, further optimization of the 16-phenyl ω-chain moiety of the γ-lactam 5-thia prostaglandin E analog and the 2-mercaptothiazole-4-carboxylic acid analog were undertaken. Rat in vivo evaluation of these newly identified compounds as their poly (lactide-co-glycolide) microsphere formulation, from which sustained release of the test compound is possible, led us to discover compounds that showed efficacy in a rat bone fracture healing model after its topical administration without serious influence on blood pressure and heart rate. A structure-activity relationship study is also presented.
