Essential yield components of potato crops are influenced by the physiological age of the tubers at planting. Previous studies have attempted to develop biophysical, physiological or biochemical markers of potato tuber ageing. This research note focuses on characterising a physiological age index (PAI) based on sprouting parameters and originally developed by Caldiz et al. [Caldiz, D.O., Fernandez, L.V., Struik, P.C., 2001. Physiological age index: a new, simple and reliable index to assess the physiological age of seed potato tubers based on the haulm killing date and length of the incubation period. Field Crop. Res. 69, 69–79]. The PAI progression of two cultivars (‘Bintje’ and ‘Désirée’) was measured and modelled over 2 harvest years. The preliminary results were consistent with other ageing markers such as the incubation period (IP) and desprouting sensitivity. Under our experimental conditions, the PAI allowed us to describe cultivar-specific and harvest year-specific age variations measured from the time the haulm (foliage) was killed and the mother plant's influence on the tubers was no longer present. By contrast, the IP data displayed a higher inherent variability that impaired their discrimination ability. Critical PAI values corresponding to the main postharvest developmental steps (e.g., dormancy, apical dominance, multiple sprouting) were then identified on the basis of emergence pattern data, allowing us to propose this index as a useful reference frame for future ageing studies.

BACKGROUND: AGM-1470 is a newly synthesized molecule developed as an analog of the potent anti-angiogenic fumagillin. Its efficacy in restraining tumor growth in vivo and the absence of major side effects have already led to phase I clinical trials in patients with solid cancers. However, neither the exact mechanisms of action of AGM-1470 nor its effects on the host of normal cells have been extensively studied. Recently, we showed that AGM-1470 enhanced the proliferation of B lymphocytes in the presence of T cells. Since AGM-1470 could potentially be used in patients with lymphoma, it was urgent to test the effect of the molecule on the proliferation of tumor lymphocytes. METHODS: The possible effect of AGM-1470 on the proliferation of normal or tumor lymphocytes was evaluated by thymidine-incorporated assays. Normal T and B lymphocytes were purified from human tonsils. The tumor lymphocytes used in the study were Molt 3, Molt 4 and Jurkatt cell lines for the T lineage and Daudi and Radji cell lines for the B lineage. RESULTS: As shown previously, AGM-1470 stimulates the proliferation of normal B lymphocytes through an action on normal T cells. THe angioinhibin was ineffective ont eh proliferation of both T and B transformed cells. Moreover, in the presence of the drug, tumor T cells co-cultured with normal B lymphocytes did not induce any increase in B cell proliferation, as previously observed with normal T lymphocytes. Inversely, tumor B cells co-cultured with normal T lymphocytes were insensitive to the drug. CONCLUSIONS: Our results demonstrate that AGM-1470 is ineffective on lymphoid tumor cell proliferation and could potentially be safely administered to lymphoma patients. [less ▲]

Background: Like human herpesvirus 2 (HHV-2) in humans, infection by caprine herpesvirus 1 in goats is associated with genital lesions, and this provides a unique model to study the efficacy and effects of anti-herpetic drugs. Methods: The antiviral activity of cidofovir was assessed in goats infected experimentally, using various therapeutic protocols. Results: Topic administration of cidofovir 1% cream prevented the onset of virus-induced genital lesions and drastically reduced virus shedding. Conclusion: Cidofovir appears to be a very efficient drug for the prevention of genital lesions caused by an alphaherpesvirus. [less ▲]

As part of our continuing research for anticancer compounds from the Walloon Region forest, EtOAc extract from Carpinus betulus leaves was phytochemically studied, leading to the bioguided isolation of pheophorbide a, which is responsible of anticancer properties of C. betulus young leaves. This compound was identified using nuclear magnetic resonance and mass spectrophotometric data and comparison with a commercial standard. Evaluation of the growth inhibitory activities of pheophorbide a using MTT colorimetric assay and phase-contrast microscopy in various human cancer cell lines confirmed the photoactivable properties of this compound. Our research showed, for the first time, the presence of pheophorbide a, a chlorophyll derived compound, which we quantified in high quantities in young leaves of C. betulus. This is in contrast with the literature which generally describes pheophorbide a as a catabolic product of chlorophyll, then preferentially present in old leaves. [less ▲]
