H and C NMR chemical shifts of 2--alkylamino-naphthalene-1,4-diones.

H as well as C chemical shifts of 32 compounds of C (3) substituted 2-(-alkylamino)-3R-naphthalene-1,4-dione (where -alkyl: methyl, to octyl, R = H, Cl, Br, and CH) are investigated through H, C, DEPT, gDQCOSY, and gHSQCAD NMR experiments and M06-2X/6-311++G (d,p) density functional theory are discussed. Single crystal X-ray structure of Br-3, as well as 18 different derivatives of naphthalene-1,4-diones, are revealed for its inter and intra-molecular hydrogen bonding interactions.

First appearance deceives many: disentangling the species complex using an integrated approach.

The gekkonid lizard genus Oken is the second most species-rich genus of geckos with greatest diversity in the tropical regions of the world. Some species of the genus are commensal and widespread; however, there are several endemic lineages with restricted distribution. India is home to at least 35 species, with 20 endemic species and the number is steadily increasing with exploration of new habitats and integrated taxonomic approach including molecular data.

A new large species of gecko of the genus Hemidactylus Oken, 1817 (Reptilia: Sauria: Gekkonidae) from the Eastern Ghats, India.

A new large species of gecko superficially resembling Hemidactylus maculatus Duméril & Bibron and its allied large Hemidactylus is described from Eastern Ghats. The new species, Hemidactylus kangerensis sp. nov.

Long-term cardiac (valvulopathy) safety of cabergoline in prolactinoma.

Background: Clinical relevance of association of cabergoline use for hyperprolactinemia and cardiac valvulopathy remains unclear.

Objective: The aim of the study was to determine the prevalence of valvular heart abnormalities in patients taking cabergoline for the treatment of prolactinoma and to explore any associations with the cumulative dose of drug used.

Design: A cross-sectional echocardiographic study was performed in patients who were receiving cabergoline therapy for prolactinoma.
