Contemplated methods and compositions further increase susceptibility of sensitized MRSA against various antibiotic drugs. Most preferably, the MRSA is already sensitized with a galloylated catechin (e.g., ECG), and further sensitization is achieved by exposure to a non-galloylated catechin (e.g., EC), and most preferably the corresponding non-galloylated catechin.

A catechin is modified in at least one position (most preferably in the 3-position of the C-ring) to increase its lipophilicity. Contemplated catechins are demonstrated to have significantly improved antibacterial properties, likely due to catastrophic membrane damage.

摘要:
There is provided a novel compound of the general formula I in which each of R8 to R10 is hydrogen, aryl, C1-6 alkyl, trialkylsilyl or acyl; R1 to R5 are individually selected from hydrogen, hydroxy, C1-6 alkoxy and acyloxy; R6 and R7 are H, C1-4 alkyl, trialkylsilyl or acyl; X is O or NR, and R is H or Me; in which any of the alkyl groups including alkyl groups in alkoxy, acyl and acyloxy groups may be substituted by aryl, C1-4 alkyl, C1-4 alkoxy, hydroxyl, trialkylsiloxy or acyloxy groups; with the proviso that R2 and R3 are not both OH when R4 is H or OH, R1 and R5 are both H, and X is O. The amide compounds (X is NR) are analogues of epigallocatechin gallate or epicatechin galate, with an amide bond in place of the natural ester bond, with resistance to hydrolysis by esterase enzymes. The ester compounds (X is O) have a different hydroxylation pattern on the B ring as compared to the natural products. The compounds may be used to modulate the resistance to β-lactam antibiotics of various infections, especially methicillin resistant Staphylococcus aureus (MRSA). Pharmaceutical compositions containing the novel compounds and combinations of the novel compounds and β-lactam antibiotics are described.
摘要:
An oesophagus seal for sealing the oesophagus in a slaughtered animal comprises a plug (10) for insertion into the oesophagus (40) and a retainer in the form of a clamp (20) which internally engages and clamps to tissues of the oesophagus (40) to resist disengagement of the plug. The plug (10) has an outer peripheral clamp surface (13) and the clamp (20) is in the form of a clamp ring (21) which clamps the internal mucosa (41) of the oesophagus (40) between the clamp ring (21) and the outside clamp surface (13). The plug (10) has a reduced diameter neck (15) and a conical ramped outer surface (16) leading to the clamp surface. The clamp ring (21) is initially located beyond the neck (15) and is advanceable so that tissues (41) surrounding and projecting into the neck portion (15), e.g. by application of a vacuum, will be pinched between the advancing clamp ring (21) and the surface (16) and, upon further advance of the clamp ring (21), the tissues (41) are pinched between the clamp ring (21) and the outer clamp surface (13). There is also provided an oesophagus sealing system comprising an applicator rod (30) having an end for mounting of the oesophagus seal, and having an associated actuator (35) which is selectively moveable axially to move the clamp (20) so as to engage and clamp the tissues (41) of the oesophagus (40) between the clamp (20) and the plug (10).
摘要:
The invention relates to decontaminating meat by locating a body of meat (10) within a chamber (15), providing a volume (25) of decontaminating water (27) sufficient to fill the chamber (15) and immerse the body of meat; supplying the decontaminating water (27) at e.g. 80.degree. C. to the chamber at multiple inlet point (31-34) accompanied by substantial turbulence as it fills the chamber (15) and discharging the decontaminating water from the chamber (15) after the body of meat (10) has been decontaminated (e.g. after ten seconds). The volume of decontaminating water (27) is provided in an elevated vessel (26) connected to the chamber (15) through a supply passage (30) of relatively large flow area. The body of meat (10) is suspended from an overhead conveyor (11) and is conveyed into the chamber (15) through an entry opening and out of the chamber (15) through an exit opening, the body of meat (10) being paused in its movement by the conveyor (11) when it has entered the chamber (15) to enable the decontaminating operation to take place.
