T., Patrut, A., Rakosy, D., Rakosy, L., Lowy, D. A., Von Redenf, K. F., & Bodis, J. Radiocarbon dating of Makuri Le boom, a very old African baobab from Nyae Nyae, Namibia. Studia Universitatis Babes-Bolyai Chemia, 65(2), (2020): 149-159, doi:10.24193/subbchem.2020.2.12.The article reports the AMS (accelerator mass spectrometry) radiocarbon dating results of Makuri Lê boom, a very large African baobab from Nyae Nyae Conservancy, Namibia. The investigation of this superlative baobab shows that it consists of 12 independent stems of different dimensions, which belong to three generations. Makuri Lê boom has an open ring-shaped structure, a type of architecture which allows baobabs to reach very large sizes and old ages. The oldest sample has a radiocarbon date of 1602 ± 17 BP, which corresponds to a calibrated age of 1520 ± 35 calendar yr. By this value, Makuri Lê boom becomes one of the oldest dated baobabs and angiosperms with accurate dating results.The research was funded by the Romanian Ministry of National Education CNCS-UEFISCDI under grant PN-III-P4-ID-PCE-2016-0776, Nr. 90/2017

The Prognostic Role of Postablative Non-Stimulated Thyroglobulin in Differentiated Thyroid Cancer
No full textThyroglobulin (Tg) is the most important tumor marker in differentiated thyroid cancer (DTC). The aim of this study was to assess the diagnostic and prognostic roles of postoperative stimulated and postablative lowest, highest, and one-year non-stimulated Tg values obtained during the follow-up of patients with DTC. In this retrospective study, 222 radioiodine-treated, anti-thyroglobulin antibody (TgAb)-negative DTC patients having at least 9 months’ follow-up time were included (172 papillary and 50 follicular cancers; median age: 48 (from 15 to 91) years; female–male ratio: 158/64; median (quartiles) follow-up time: 54 (22–97) months). The 2015 American Thyroid Association guidelines were applied as criteria of the therapeutic response. Postoperative stimulated Tg values had significantly lower diagnostic accuracy than any of the non-stimulated postablative Tg values. One-year non-stimulated Tg had excellent prognostic value for structural disease: a cut-off value of 0.85 ng/mL had an 88.1% diagnostic accuracy. If the Tg value did not decrease below 0.75 ng/mL at any time during follow-up, the risk of residual disease was 25 times higher. The highest non-stimulated Tg during follow-up was the best predictor of residual disease (e.g., a Tg value exceeding 7.7 ng/mL indicated a 30-fold increase in risk). Non-stimulated Tg values measured during follow-up have excellent diagnostic accuracy to predict structural disease in DTC patients. The risk classification of a patient can safely be modified based on even a single Tg measurement

African baobabs with double closed ring-shaped structures and two separate false cavities : radiocarbon investigation of the baobab of Golconda Fort
No full textAuthor Posting. © Studia Chemia, 2016. This article is posted here by permission of Studia Chemia for personal use, not for redistribution. The definitive version was published in Studia Chemia 2016, no. 4 (2016): 21-30.The article discloses the results of radiocarbon investigation
of the baobab of Golconda Fort, Hyderābād, India, which is the largest
African baobab outside Africa. Two wood samples were collected from
the large inner cavity; of these we extracted several segments for AMS
(accelerator mass spectrometry) radiocarbon dating. The oldest sample
segment had a radiocarbon date of 342 ± 22 BP, which corresponds to a
calibrated age of 430 ± 20 yr. We estimate that the oldest part of the
baobab has an age of 475 ± 50 yr. The investigation of the baobab of
Golconda Fort revealed that it consists of 6 + 2 fused stems. Six stems
build two rings that close two distinct false cavities, while two additional
stems are located outside the rings. We called this new type of architecture
double closed ring-shaped structure with two separate false cavities.The research was funded by the Romanian Ministry of National Education

The definitive version was published in Studia Universitatis Babes-Bolyai, Seria Chemia 62, no. 2, Tom 2 (2017): 355-364, doi:10.24193/subbchem.2017.2.28.The article reports the AMS (accelerator mass spectrometry)
radiocarbon dating results of Sagole Big tree, a giant African baobab from
Limpopo, South Africa. Several wood samples were collected from the walls
of its inner cavity and dated by radiocarbon. The age values along the cavity
samples increase with the distance into the wood. This anomaly shows that
the cavity is a false one. The oldest sample segment had a radiocarbon date
of 781 ± 29 BP, which corresponds to a calibrated age of 740 ± 15 yr. We
estimate that the oldest part of the Sagole baobab has an age of 800-900 yr.
We determined that the tree has a closed ring-shaped structure, which
consists of a large unit with six fused stems and of two additional leaning
stems.The research was funded by the Romanian Ministry of Scientific Research CNCSUEFISCDI

The definitive version was published in Studia Universitatis Babes-Bolyai, Seria Chemia 63, no. 3 (2018): 41-48, doi:10.24193/subbchem.2018.3.03.The article reports the AMS (accelerator mass spectrometry) radiocarbon investigation results of the old common ash of Aiton. Five wood samples were collected from the trunk of the tree. The deepest ends of the samples were analysed by AMS radiocarbon. We found radiocarbon dates between 165 ± 20 BP and 240 ± 18 BP, which correspond to calibrated ages of 230 – 360 years. These results, combined with a ring counting estimate, indicate an age of 330 ± 30 years for the ash of Aiton. By this value, the ash of Aiton becomes the oldest known common ash with accurate dating results.The research was funded by the Romanian Ministry of Research and Innovation CNCS-UEFISCDI under grant PN-III-P4-ID-PCE-2016-0776, Nr. 90/2017
