Thymidine kinase is an enzyme, a phosphotransferase (a kinase): 2'-deoxythymidine kinase, ATP-thymidine 5'-phosphotransferase, EC 2.7.1.21. It can be found in most living cells. It is present in two forms in mammalian cells, TK1 and TK2. Certain viruses also have genetic information for expression of viral thymidine kinases. Thymidine kinase catalyzes the reaction:Thd + ATP → TMP + ADPwhere Thd is (deoxy)thymidine, ATP is adenosine triphosphate, TMP is (deoxy)thymidine monophosphate and ADP is adenosine diphosphate.Thymidine kinases have a key function in the synthesis of DNA and therefore in cell division, as they are part of the unique reaction chain to introduce thymidine into the DNA. Thymidine is present in the body fluids as a result of degradation of DNA from food and from dead cells. Thymidine kinase is required for the action of many antiviral drugs. It is used to select hybridoma cell lines in production of monoclonal antibodies. In clinical chemistry it is used as a proliferation marker in the diagnosis, control of treatment and follow-up of malignant disease, mainly of hematological malignancies.

The genus Thymus (/ˈtaɪməs/; thymes) contains about 350 species of aromatic perennial herbaceous plants and subshrubs to 40 cm tall in the family Lamiaceae, native to temperate regions in Europe, North Africa and Asia.Stems tend to be narrow or even wiry; leaves are evergreen in most species, arranged in opposite pairs, oval, entire, and small, 4–20 mm long, and usually aromatic.

The genus Thymus (/ˈtaɪməs/; thymes) contains about 350 species of aromatic perennial herbaceous plants and subshrubs to 40 cm tall in the family Lamiaceae, native to temperate regions in Europe, North Africa and Asia.Stems tend to be narrow or even wiry; leaves are evergreen in most species, arranged in opposite pairs, oval, entire, and small, 4–20 mm long, and usually aromatic. Thyme Flowers are in dense terminal heads, with an uneven calyx, with the upper lip three-lobed, yellow, white or purple.Several members of the genus are cultivated as culinary herbs or ornamentals, when they are also called thyme after its best-known species, Thymus vulgaris or common thyme.Thymus species are used as food plants by the larvae of some Lepidoptera (butterfly and moth) insect species, including Chionodes distinctella and the Coleophora case-bearers C. lixella, C. niveicostella, C. serpylletorum and C. struella (the latter three feed exclusively on Thymus).

Thurii (/ˈθʊərɪaɪ/; Greek: Θούριοι Thoúrioi), called also by some Latin writers Thurium (compare Greek: Θούριον in Ptolemy), for a time also Copia and Copiae, was a city of Magna Graecia, situated on the Tarentine gulf, within a short distance of the site of Sybaris, whose place it may be considered as having taken. The ruins of the city can be found in the Sybaris archaeological park near Sibari in the Province of Cosenza, Calabria, Italy.

Thymiatris microloga is a moth in the Xyloryctidae family. It was described by Diakonoff in 1966. It is found on Java.The wingspan is 37-41 mm. The forewings are pure white, dusted coarsely throughout with dark fuscous-grey and with a continuous streak of the same colour along the costa, narrowed in the middle, confluent with a similar but narrower irregular streak along the upper edge of the cell.

Thymiatris microloga is a moth in the Xyloryctidae family. It was described by Diakonoff in 1966. It is found on Java.The wingspan is 37-41 mm. The forewings are pure white, dusted coarsely throughout with dark fuscous-grey and with a continuous streak of the same colour along the costa, narrowed in the middle, confluent with a similar but narrower irregular streak along the upper edge of the cell. The veins above and beyond cell, as far as vein 2, are narrowly streaked with the same colour, as also is the discoidal vein. There is sometimes an inwardly-oblique series of short darker streaks along the veins, this series runs from the costa before the apex to the dorsum well before the tornus. A series of rather large pale ochreous spots is found on the ends of veins 3 to 9, becoming smaller on both ends of the series, surrounded by brownish-ferruginous scales. The hindwings are glossy ochreous-grey, along the upper part of the termen and in the apex narrowly pale ochreous strewn with dark brown.
