Caloric restriction modifies spatiotemporal calcium dynamics in mouse hippocampal astrocytes.

Biochim Biophys Acta Mol Cell Res 2021 Jun 6;1868(7):119034. Epub 2021 Apr 6.

We analysed spatiotemporal properties of Ca signals in protoplasmic astrocytes in the CA1 stratum radiatum of hippocampal slices from young (2-3 months old) mice housed in control conditions or exposed to a caloric restriction (CR) diet for one month. The astrocytic Ca events became shorter in duration and smaller in size; they also demonstrated reduced velocity of expansion and shrinkage following CR. At the same time, Ca signals in the astrocytes from the CR animals demonstrated higher amplitude and the faster rise and decay rates. Read More

Mechanisms of Cr(VI) resistance by endophytic Sphingomonas sp. LK11 and its Cr(VI) phytotoxic mitigating effects in soybean (Glycine max L.).

Ecotoxicol Environ Saf 2018 Nov 28;164:648-658. Epub 2018 Aug 28.

School of Applied Biosciences, Kyungpook National University, Daegu 41566, Republic of Korea. Electronic address:

Chromium Cr(VI) is highly toxic and leads to impaired phenotypic plasticity of economically important crops. The current study assessed an endophytic-bacteria assisted metal bio-remediation strategy to understand stress-alleviating mechanisms in Glycine max L (soybean) plants inoculated with Sphingomonas sp. LK11 under severe Cr(VI) toxicity. Read More

Photosynthesis performance, antioxidant enzymes, and ultrastructural analyses of rice seedlings under chromium stress.

Environ Sci Pollut Res Int 2016 Jan 23;23(2):1768-78. Epub 2015 Sep 23.

Jiangsu Key Lab of Biodiversity and Biotechnology, School of Life Sciences, Nanjing Normal University, No. 1 Wenyuan Road, Nanjing, 210023, Jiangsu, China.

The present study was conducted to examine the effects of increasing concentrations of chromium (Cr(6+)) (0, 25, 50, 100, and 200 μmol) on rice (Oryza sativa L.) morphological traits, photosynthesis performance, and the activities of antioxidative enzymes. In addition, the ultrastructure of chloroplasts in the leaves of hydroponically cultivated rice (O. Read More

Late relapse of acute promyelocytic leukemia treated with all- trans retinoic acid and chemotherapy: report of two cases.

Ann Hematol 2004 Jul 17;83(7):484-6. Epub 2004 Jan 17.

Division of Hematology and Stem Cell Transplantation Unit, Cardarelli Hospital, Via Nicolò Piccinni 6, 80128 Napoli, Italy.

Two patients with acute promyelocytic leukemia (APL) relapsed at 111 and 84 months after achievement of complete remission (CR) induced by a combination of all- trans retinoic acid and chemotherapy. In both patients molecular remission, obtained after consolidation, had been confirmed at 60 months from CR achievement. At relapse, morphological, immunophenotypic, cytogenetic, and molecular analyses showed findings identical to those at diagnosis. Read More

Two different types of concomitant resistance induced by murine tumors: morphological aspects and intrinsic mechanisms.

Oncol Rep 2000 Sep-Oct;7(5):1053-63

Division Medicina Experimental, Instituto de Investigaciones Hematologicas and Instituto de Estudios Oncologicos, Academia Nacional de Medicina, 1425 Buenos Aires, Argentina.

Concomitant resistance (CR) is the phenomenon according to which a tumor-bearing host inhibits the growth of a secondary implant of the same tumor at a distant site. Confirming and extending previous results of our laboratory, histological studies have revealed that two temporally separate peaks of CR can be detected throughout tumor evolution. The first peak induced by immunogenic small tumors, in euthymic but not in nude mice, is associated with extensive necrosis of the secondary tumor implant and a profuse infiltration of polymorphonuclear granulocytes and mononuclear cells resulting in its final destruction; these features correspond to a typical immunological rejection.
