  • Patent number: 11941301
    Abstract: A technique maintains online access to data stored in a plurality of storage devices during a hardware upgrade in which the plurality of storage devices moves between storage processor enclosures. The technique involves providing, from the plurality of storage devices, online access to the data while each storage device of the plurality of storage devices resides in a first storage processor enclosure. The technique further involves providing, from the plurality of storage devices, online access to the data while the plurality of storage devices is moved from the first storage processor enclosure to a second storage processor enclosure (e.g., transferring each storage devices one by one before triggering a rebuild process). The technique further involves providing, from the plurality of storage devices, online access to the data while each storage device of the plurality of storage devices resides in the second storage processor enclosure.

  • Patent number: 11933753
    Abstract: The present application describes a sensor apparatus based on chemically functionalized graphene as the sensing materials. The sensing materials is modified from graphene oxide with unique chemical process to form a group of graphene derivatives, e.g. butylamine, hexylamine, decylamine, dodecylamine, benzylamine etc., to detect volatile and non-volatile compounds, e.g. toluene, ethylacetate, ethanol, acetone, hexane etc. with high sensitivity. Pattern recognition algorithms and methods, e.g. PCA, are coupled with the sensors for detecting and quantifying specific chemical compounds. Methods of using the sensor apparatus in applications such as diagnosis of disease and food quality control are disclosed.

  • Patent number: 11607423
    Abstract: The present invention in the field of cancer therapeutics is based on the finding (illustrated in FIG. 4) that when cannabinoids are administered to cancer cells after a chemotherapeutic agent has been administered, the combined treatment leads to lower cancer cell viability than administration of the chemotherapeutic agent alone. There is provided a pharmaceutical composition comprising a chemotherapeutic agent for use in the treatment of breast cancer, wherein said treatment comprises a first phase in which the chemotherapeutic agent is administered, and a subsequent second phase in which a cannabinoid is administered.

  • Publication number: 20220362168
    Abstract: The present invention in the field of cancer therapeutics is based on the finding that when cannabinoids are administered to cancer subjects after a chemotherapeutic agent has been administered, the combined treatment leads to increased survival prognosis, a reduction in disease progression, stabilisation of disease state and inhibition of tumour growth than administration of the chemotherapeutic agent alone. There is provided a pharmaceutical composition comprising a chemotherapeutic agent for use in the treatment of bladder, brain and spinal cord, colorectal, head and neck, lung, lymphoma, neuroendocrine, oesophageal, ovarian, pancreatic and prostate cancer, wherein said treatment comprises a first phase in which the chemotherapeutic agent is administered, and a subsequent second phase in which a cannabinoid is administered.

  • Publication number: 20220196659
    Abstract: The invention relates to a method for monitoring the treatment of a subject undergoing therapy with an active that is naltrexone or a metabolite or analogue thereof, comprising: a. measuring the level of pERK in a sample obtained from the subject undergoing treatment; b. comparing the level of pERK with a reference, wherein if the pERK level is increased compared to the reference, then the active is being administered at an effective level.

  • Publication number: 20220143010
    Abstract: The present invention is based on the finding that the inhibition of the proliferation of cancer cells by cannabinoids is brought about more effectively by combined treatment with low dose naltrexone (LDN) or 6-?-naltrexone (6BN), a metabolite of naltrexone. There is provided a pharmaceutical composition comprising naltrexone or a metabolite thereof or an analogue thereof, for use in the treatment of cancer within a subject, wherein a therapeutically effective amount of the naltrexone or metabolite thereof or analogue of either is to be administered to the subject in a first treatment phase, wherein after the first treatment phase the subject is to be administered a therapeutically effective amount of a cannabinoid in a second treatment phase, and wherein the subject is to be administered a chemotherapeutic agent before, during or following the treatment.

  • Publication number: 20210308072
    Abstract: The present invention relates to the use of a combination of two different cannabinoids in the treatment of leukaemia. The combination of CBD with THC appears to be particularly effective in reducing cell number in this disease. Preferably the cannabinoids are used in the form of an extract of cannabis such that many of the naturally occurring compounds are co-extracted with the THC or CBD. Alternatively, the cannabinoids are present in the form of a highly purified extract of cannabis, wherein the CBD or THC are present at greater than 98% of the total extract (w/w) and the other components of the extract are characterized. Alternatively, the CBD and THC may be synthetically produced. A specific ratio of CBD and THC such as 10:1 to 1:10 (CBD:THC) or more preferably between 2:1 to 1:2 (CBD:THC) may be used.
