Results: Five compounds were isolated from the most active and least cytotoxic ethylacetate LY2606368 in vitro sub-extract: betulinic acid (HLT1), 2,2′,5,6′-tetrahydroxybenzophenone (HLT2), 5-hydroxy-3-methoxyxanthone

(HLT3), 3-hydroxy-5-methoxyxanthone (HLT4) and HLT0 (yet to be identified). Three of the tested compounds presented significant anti-plasmodial activities (with 50% inhibitory concentration, IC(50) < 5 mu M), with 5-hydroxy-3-methoxyxanthone exerting the highest activity, followed by HLT0 and betulinic acid. All the compounds with significant anti-plasmodial activity were non-cytotoxic, except betulinic acid which showed a 50% cytotoxic concentration, CC(50) of 25 mu g/mL.

Conclusions: These findings justify the use of H. lanceolatum stem bark as anti-malarial by traditional healers of Western Cameroon, and could constitute a good basis for further studies towards development of new drug candidates or phytomedicines for malaria.”
“Internal PF-00299804 in vitro root resorption is an uncommon lesion following a dental injury. The use of mineral trioxide aggregate (MTA) is a conservative approach to repair lesions with periodontal communication. This case report presents a long-term follow-up of a nonsurgical endodontic management using MTA for perforative defect of internal root resorption.

During the endodontic treatment, the granulation tissue was removed and the root canal prepared. Calcium hydroxide was placed as a temporary dressing for 30 days. After this period, the root canal space and the perforation

defect were filled with MTA. The clinical findings and periapical radiographs indicated success of treatment until 2 years of follow-up. However, the radiograph after 8 years showed an extensive radiolucent area in the middle third of the root with separation of the apical and coronal root segments. These findings were observed more accurately by using cone-beam computerized Selleck Evofosfamide tomography. (Oral Surg Oral Med Oral Pathol Oral Radiol Endod 2010;110:784-788)”
“Although the role of CD14 in mediating signals from Toll-like receptors to recognize Mycobacterium tuberculosis is known, how polymorphisms in this gene affect the susceptibility to develop tuberculosis are still not clear. We examined whether single nucleotide polymorphisms at positions -1145 and -159 in the promoter region of the CD14 gene are associated with tuberculosis in a Chinese Han population in a case-control study of 432 Chinese patients with tuberculosis and 404 ethnically matched healthy controls. Genotyping was performed to identify polymorphisms of the CD14 gene by PCR-DNA sequencing. Both the frequency of allele T in the C(-159) T polymorphism (odds ratio (OR) = 1.4; 95% confidence interval (95%CI) = 1.148-1.708) and allele G in the G(-1145) A polymorphism (OR = 1.512; 95%CI = 1.236-1.849) were significantly more frequent in cases than in controls.
