The constituents of essential oils isolated by hydrodistillation of the overground parts of Origanum majorana and Origanum floribundum from Algeria were examined by GC and GC-MS. A total of thirty eight and thirty seven components were identified accounting for 93.3 % and 88.9 %, respectively, of the oils of O. majorana and O. floribundum. The oil of O. majorana (yield: 1.2 %) contained, as main components, β-caryophyllene (26.0 %), α-terpinolene (14.7 %), γ-terpinene (10.9 %) and sabinene (9.5 %). Major compounds in the volatile oil of O. floribundum (yield: 1.6 %) were γ-terpinene (34.1 %), p-cymene(27.6 %) and carvacrol (9.6 %). [less ▲]

Wildebeests carry asymptomatically alcelaphine herpesvirus 1 (AlHV-1), a gamma-herpesvirus inducing malignant catarrhal fever (MCF) to several ruminant species (including cattle). This acute and lethal lymphoproliferative disease occurs after a prolonged asymptomatic incubation period after transmission. Our recent findings with the rabbit model indicated that AlHV-1 infection is not productive during MCF. Here, we investigated whether latency establishment could explain this apparent absence of productive infection and sought to determine its role in MCF pathogenesis. First, whole-genome cellular and viral gene expression analyses were performed in lymph nodes of MCF-developing calves. Whereas a severe disruption in cellular genes was observed, only 10% of the entire AlHV-1 genome was expressed, contrasting with the 45% observed during productive infection in vitro. In vivo, the expressed viral genes included the latency-associated nuclear antigen homolog ORF73 but none of the regions known to be essential for productive infection. Next, genomic conformation analyses revealed that AlHV-1 was essentially episomal, further suggesting that MCF might be the consequence of a latent infection rather than abortive lytic infection. This hypothesis was further supported by the high frequencies of infected CD8+ T cells during MCF using immunodetection of ORF73 protein and single-cell RT-PCR approaches. Finally, the role of latency-associated ORF73 was addressed. A lack of ORF73 did not impair initial virus replication in vivo, but it rendered AlHV-1 unable to induce MCF and persist in vivo and conferred protection against a lethal challenge with a WT virus. Together, these findings suggest that a latent infection is essential for MCF induction. [less ▲]

Frailty in the elderly is an important factor of morbidity, particularly in the setting of surgery. The various pathologies that can lead to a functional decline are well known. The risk of mortality and morbidity should be assessed as a function of the nature of the surgical procedure and of the disease for which it is required; the factors of severity, the predictable duration of the procedure, and the expected blood losses must also be taken into account. The thrombo-embolic risk should finally be considered. In the elderly, one may say that the functional risk matters more than the vital risk. Frailty must be integrated into the risk assessment; however, further studies are needed to better determine the impact of that new concept. Undoubtedly, the cognitive and nutritional status are of main importance. A better knowledge of the risks should lead to validate specific interventions that could help to prevent surgical complications, shorten the length of hospital stay, and protect the self-sufficiency of the aged.
