- Description:
- Toxoplasmosis is a common parasitic disease caused by Toxoplasma gondii (Nicolle et Manceaux, 1908), an obligate parasite capable of infecting a range of cell types in almost all warm-blooded animals. Upon infecting an intermediate host, the parasites differentiate into tachyzoites which rapidly infect host tissues. Usually, the invading parasites are cleared by the immune system and administered drugs, but some tachyzoites differentiate into bradyzoites forming tissue cysts. These tissue cysts could serve as a source for re-infection and exacerbations. Currently, treatment for toxoplasmosis is limited and, moreover, there are no drugs for treating the cystic stage thus rendering toxoplasmosis a global burden. Recently, we demonstrated that inorganic nanoparticles showed promising activity against the tachyzoite stage T. gondii. In the present study, we evaluated nanoparticles for effect on bradyzoite formation in vitro. Data revealed that the nanoparticles limited bradyzoite burden in vitro. Further, the nanoparticles decreased the bradyzoite-specific BAG-1 promoter activity relative to the untreated control under a bradyzoite-inducing culture condition, even though this reduction in BAG-1 promoter activity waned with increasing concentrations of nanoparticles. In contrast, a parallel experiment under normal cell culture conditions showed that the nanoparticle treatment mildly increased the BAG-1 promoter activity relative to the untreated control. Taken together, the findings are evidence that nanoparticles not only possess anti-tachyzoite potential but they also have anti-bradyzoite potential in vitro., Oluyomi Stephen Adeyemi, Yuho Murata, Tatsuki Sugi, Yongmei Han, Kentaro Kato., and Obsahuje bibliografii

- Description:
- This paper introduces a very interesting group of curculionid beetles – weevils of the tribe Cleonini. This tribe includes quite a remarkable large species associated with non-forest habitats, most of which are currently considered endangered. In spite of being very popular among coleopterists, this group of beetles has not been studied in detail within the Czech Republic. and Robert Stejskal, Filip Trnka.

- This paper introduces a very interesting group of curculionid beetles–weevils of the tribe Lixini. This tribe includes a quite re-markable large species, most of which are currently considered endangered. They are associated with non-forest habitats and re-quire various kinds of habitat disturbation which ensures their successful survival., Robert Stejskal, Filip Trnka., and 13 barev. fot.

- Description:
- V příspěvku je popsán objev larvy jednoho z nejtajemnějších krasců Austrálie – Julodimorpha saundersii. Díky objevu larvy bylo vyjasněno taxonomické postavení rodu na základě srovnávací, larvální morfologie. Nehledě na morfologickou podobnost dospělců rodů Julodimorpha a Julodis (podčeleď Julodinae) bylo na základě larválních znaků potvrzeno, že rod Julodimorpha je samostatným primitivním tribem podčeledi Buprestinae. Objev larvy tohoto rodu je typickým příkladem náhody, která je někdy nutná i při vědeckém zkoumání. Další příklad takové výjimečné náhody je ilustrován na objevu larvy dalšího krasce, Coomaniella violaceipennis z Thajska, jehož larvy se vyvíjejí v korunových liánách pralesních velikánů., The discovery of the larva of one of the most enigmatic Australian Buprestid beetles, Julodimorpha saundersii, is briefly discussed. The taxonomic position of the genus has been clarified using comparative larval morphology. Regardless of the morphological similarity of the adults with the genus Julodis (subfamily Julodinae), the larval characteristics of the genus Julodimorpha confirmed its placement as an independent, primitive tribe of the subfamily Buprestinae. Another example of good luck in scientific research is described, concerning buprestid beetle Coomaniella violaceipennis from Thailand, larvae of which are borers in the canopy climbers., and Svatopluk Bílý.

- Description:
- The monotypic genus Silvispina M. Wang & Soulier-Perkins, gen. n. and new species S. changpotou M. Wang & Soulier-Perkins, sp. n. belonging to the family Lophopidae Stål, 1866, from Yunnan Province in China, is described and illustrated. The peculiarity of the first metatarsal segment of this genus is stressed and the taxonomic position of this new genus is discussed. The ornamentation and shape of metatibia and first tarsal segment (the characters that currently distinguish the subfamilies Menoscinae and Lophopinae) do not agree with either subfamily and the new genus is placed as incertae sedis in the Lophopidae. The genus Ridesa Schumacher, 1915 is removed from the family Lophopidae and placed in the Achilidae., Menglin Wang, Yinglun Wang, Adeline Soulier-Perkins., and Obsahuje bibliografii
