We report here on the development and validation of a prototype Invader Plus method for the qualitative detection of herpes simplex virus types 1 and 2 in cerebrospinal fluid (CSF). The method combines PCR and Invader techniques in a single, closed-tube, continuous-reaction format that gives an analytical sensitivity of approximately 10 copies per reaction. The clinical sensitivity and specificity were 100.0% and 98.6%, respectively, when the results of the method were validated against the results obtained with a PCR colorimetric microtiter plate system by use of clinical CSF specimens.

Numerous management methods are deployed to try to mitigate the destructive impact of weedy and invasive populations. Yet, such management practices may cause these populations to inadvertently evolve in ways that have consequence on their invasiveness. To test this idea, we conducted a two-step field mesocosm experiment; we evolved genetically diverse populations of the duckweed to targeted removal management and then tested the impact of that evolution in replicated invasions into experimental resident communities.

Glioblastoma multiforme (GBM), the most aggressive primary brain tumour, exhibits low survival rates due to its rapid growth, infiltrates surrounding brain tissue, and is highly resistant to treatment. One major challenge is oedema infiltration, a fluid build-up that provides a path for cancer cells to invade other areas. MRI resolution is insufficient to detect these infiltrating cells, leading to relapses despite chemotherapy and radiotherapy.

Background: Human adamantinomatous craniopharyngioma (ACP) is a brain tumor that originates at the base of the skull and shows aggressive local behavior, invading sensitive structures such as the optic pathways and hypothalamus. The conventional treatment of the tumor has been surgery and radiotherapy with the consequent development of serious sequelae. It is well known that Substance P (SP) peptide and Neurokinin-1 receptor (NK-1R) are involved in inflammation and cancer progression and its blockage with NK-1R antagonists has been shown to effectively counteract tumor development in preclinical trials.

Background: Total vascular exclusion (TVE) with liver hypothermic perfusion under venovenous bypass (VVB) is usually needed to perform hepatectomy with Inferior vena cava and hepatic veins resection-reconstruction. An alternative technique is represented by liver resection under intermittent pedicular clamping, IVC total clamping and VVB, without cold perfusion and liver outflow drainage through the VVB. PATIENTS AND METHODS: The patient is a 60-year-old woman with past medical history of right hepatectomy for leiomyosarcoma 14 years previously.
