Stellenbosch University is a leading public research university situated in the town of Stellenbosch, South Africa. Other nearby universities are the University of Cape Town and University of the Western Cape.Stellenbosch University designed and manufactured Africa's first microsatellite, SUNSAT, launched in 1999.Stellenbosch University was the first African university to sign the Berlin Declaration on Open Access to Knowledge in the science and Humanities.The students of Stellenbosch University are nicknamed Maties. Some claim the term arises from their maroon rugby colours: a tamatie is the Afrikaans translation for tomato. It is more likely to come from the Afrikaans colloquialism maat originally used diminutively by the students of the University of Cape Town's precursor, the South African College. Wikipedia.

The use of plant material from the Prosopis glandulosa tree (commonly known as Honey mesquite) is described for aiding sporting ability, and in particular for preventing and/or treating muscle injury and enhancing muscle strength. The plant material is typically the dried and ground pods from the tree, but could also be from other parts of the tree, such as the leaves, bark or roots.

A method for diagnosing tuberculous meningitis (TBM) is described herein. A fluid sample from a subject suspected of having TBM is tested for the presence of at least two of Interleukin-13 (IL-13), Vascular endothelial growth factor (VEGF), Cathelicidin (LL-37), IL- 7, IL-12p70, IFN-, IL-6, IL-10, IL-13, IP-10, MIP-1a, MIP-1b, RANTES and GM-CSF. Increased levels of at least any two of these biomarkers in the sample compared to levels in subjects without TBM are indicative that the subject has TBM.

A device for detecting target biomolecules is provided. The device consists of an electrically conductive membrane having a biological recognition component configured to bind a target biomolecule immobilized thereon. The membrane is connected to an electric circuit by means of electrodes. A voltage source applies a voltage to the membrane and a resistance monitoring device monitors the resistance of the membrane as a selected volume of fluid sample suspected of containing the target biomolecule is delivered onto the membrane.

The present invention is directed to a yeast strain, or strains, secreting a full suite, or any subset of that full suite, of enzymes to hydrolyze corn starch, corn fiber, lignocellulose, (including enzymes that hydrolyze linkages in cellulose, hemicellulose, and between lignin and carbohydrates) and to utilize pentose sugars (xylose and arabinose). The invention is also directed to the set of proteins that are well expressed in yeast for each category of enzymatic activity. The resulting strain, or strains can be used to hydrolyze starch and cellulose simultaneously. The resulting strain, or strains can be also metabolically engineered to produce less glycerol and uptake acetate. The resulting strain, or strains can also be used to produce ethanol from granular starch without liquefaction. The resulting strain, or strains, can be further used to reduce the amount of external enzyme needed to hydrolyze a biomass feedstock during an Simultaneous Saccharification and Fermentation (SSF) process, or to increase the yield of ethanol during SSF at current saccharolytic enzyme loadings. In addition, multiple enzymes of the present invention can be co-expressed in cells of the invention to provide synergistic digestive action on biomass feedstock. In some aspects, host cells expressing different heterologous saccharolytic enzymes can also be co-cultured togetherand used to produce ethanol from biomass feedstock.

A method for diagnosing tuberculosis (TB) is provided. The method comprises the step of detecting a panel of at least four biomarkers in an unstimulated blood sample from a subject, the biomarkers being selected from the group consisting of complement C3, complement factor H, alpha-2-macroglobulin, apolipoprotein (APO)-A1, apolipoprotein APO-CII I, apolipoprotein APO-E, pre-albumin interferon (IFN)-, interferon (IFN)-2, interferon inducible protein (IP)-10, tumour necrosis factor (TNF)-, epidermal growth factor (EGF), macrophage inflammatory protein ()-1 , soluble CD40 ligand (sCD40L), transforming growth factor (TGF)-a, vascular endothelial growth factor (VEGF), interleukin 1 receptor antagonist (IL-1 ra), matrix metallo-proteinase (MMP)-2, matrix metallo- proteinase (MMP)-9, haptoglobulin, c-reactive protein (CRP), serum amyloid A (SAA), procalcitonin (PCT), ferritin, tissue plasminogen activator (TPA), fibrinogen and serum amyloid A (SAA). The panel may include more than four biomarkers from the list described above, such as five, six, seven or even more of the biomarkers listed above. A device for performing the method is also provided.

A thermal energy storage facility (1, 61, 53) is provided that consists of a packed bed (5, 65) with an essentially unconstrained outer region (7, 67) and a duct having a heat exchange end region (13, 73) located within a central lower region of the packed bed (5, 65) and a fluid supply end (11, 71) opposite the heat exchange end region (13, 73). The heat exchange end region (13, 73) of the duct permits heat transfer fluid at an elevated temperature to pass from the duct to the packed bed (15, 75) during a charge cycle to heat the packed bed from an inner region outwards. The heat transfer fluid is drawn from the packed bed (5, 65) into the duct (3, 63) during a discharge cycle.

The invention provides a method and system for controlling the conversion of crystalline insoluble cellulose to an organic product in a bioreactor containing crystalline insoluble cellulose and a culture medium. A processor of a computing device receives an input from a sensor in the bioreactor. The input may be a measurement of one or more of concentration, temperature, pH and pressure. The processor calculates conversion of cellulose using the input to provide a total calculated organic product in the bioreactor. The processor receives a further input from a sensor in the bioreactor of the total actual organic product and compares the total calculated organic product and the total actual organic product. The processor then transmits an instruction to an agitator associated with the bioreactor to control agitation of the content of the bioreactor if the total actual organic product is outside a predetermined range of the total calculated organic product.

A method and system (100) for measuring a surface tension of a liquid is provided. The method is carried out using an electrospraying apparatus (103) connected in the system (100). At a first step a voltage source (113) applies a voltage between a capillary (107) through which the liquid is drawn and an electrode (111) of the electrospraying apparatus (103). An ammeter (115) continuously measures current flowing in the system (100) and if no current or a current less than a predetermined threshold current is measured in the system (100), the strength of the electric field at the capillary (107) is increased. As soon as current is measured in the system (100), a reading of a parameter of the system (100) is taken, which is used to calculate the surface tension of the liquid.

Suitable products include medical devices (e.g. a catheter), wound dressings, food packaging, containers, wrappings, surfaces or devices used in the processing, transport or storage of food, filters, composites, paper, wrapping materials, walls, work surfaces, floors, pipes or the like. The composition could be used to disinfect or sterilise a material, surface or product or to inhibit formation of biofilms and/or biofouling on the surface of the product to which it is applied.

A method for inhibiting or reducing haze in a liquid consumable, such as wine, is provided. Cells or a cell-wall extract of a Saccharomyces strain which has a higher level of chitin in its cell walls than a naturally occurring Saccharomyces cerevisiae strain are added to the liquid consumable, and chitinase in the liquid consumable is allowed to bind to the chitin in the Saccharomyces cell walls. Removal of the Saccharomyces cells or cell-wall extract from the liquid consumable thus also removes the chitinase, thereby inhibiting or reducing haze formation. Suitable Saccharomyces strains for use in the invention include Saccharomyces paradoxus strains and Saccharomyces cerevisiae strains which have been genetically modified or grown under environmental conditions which result in the strain having a higher than usual cell-wall chitin content.
