A water soluble, biodegradable ABA- or BAB-type tri-block polymer is disclosed that is made up of a major amount of a hydrophobic A polymer block made of a biodegradable polyester and a minor amount of a hydrophilic polyethylene glycol(PEG) B polymer block, having an overall average molecular weight of between about 2000 and 4990, and that possesses reverse thermal gelation properties. Effective concentrations of the tri-block polymer and a drug may be uniformly contained in an aqueous phase to form a drug delivery composition. At temperatures below the gelation temperature of the tri-block polymer the composition is a liquid and at temperatures at or above the gelation temperature the composition is a gel or semi-solid. The composition may be administered to a warm-blooded animal as a liquid by parenteral, ocular, topical, inhalation, transdermal, vaginal, transurethral, rectal, nasal, oral, pulmonary or aural delivery means and is a gel at body temperature. The composition may also be administered as a gel. The drug is released at a controlled rate from the gel which biodegrades into non-toxic products. The release rate of the drug may be adjusted by changing various parameters such as hydrophobic / hydrophilic component content, polymer concentration, molecular weight and polydispersity of the tri-block polymer. Because the tri-block polymer is amphiphilic, it functions to increase the solubility and / or stability of drugs in the composition.

Cell lines having genetically modified glycosylation pathways that allow them to carry out a sequence of enzymatic reactions, which mimic the processing of glycoproteins in humans, have been developed. Recombinant proteins expressed in these engineered hosts yield glycoproteins more similar, if not substantially identical, to their human counterparts. Thelower eukaryotes, which ordinarily produce high-mannose containing N-glycans, including unicellular and multicellular fungi are modified to produce N-glycans such as Man5GlcNAc2 or other structures along human glycosylation pathways. This is achieved using a combination of engineering and / or selection of strains which: do not express certain enzymes which create the undesirable complex structures characteristic of the fungal glycoproteins, which express exogenous enzymes selected either to have optimal activity under the conditions present in the fungi where activity is desired, or which are targeted to an organelle where optimal activity is achieved, and combinations thereof wherein the genetically engineered eukaryote expresses multiple exogenous enzymes required to produce “human-like” glycoproteins.

Method for digitally determining the daily insulin regimen for a diabetic patient. The invention divides the patient's day into adjustable time intervals containing basal insulin dosage rates and Carbohydrate-to-Insulin Ratio(s) (for determining meal insulin doses). The invention identifies the Corrective Insulin doses over a time interval as an “error” in the Prescription Insulin (Basal Insulin+Meal Insulin). Methods involve first estimating the change to one of these two components of Prescription Insulin, and then determining the change to the other by subtracting from the error. One method estimates Change in Meal Insulin distributed among intervals proportional to old Meal Insulin. Another method lumps After-Meal Corrective Insulin together with Meal Insulin. Another method splits the interval at the After-Meal Corrective Dose and determines Basal from Time-Boundary Corrective Dose. Data may be obtained from the previous day, and a small fraction of error applied, leading to asymptotic reduction of error. Data may be obtained from recent history, and a larger fraction of error applied by doctor or automatic method.

The invention provides for a polyvalent protein complex (PPC) comprising two polypeptide chains generally arranged laterally to one another. Each polypeptide chain typically comprises 3 or 4 “v-regions”, which comprise amino acid sequences capable of forming an antigen binding site when matched with a corresponding v-region on the opposite polypeptide chain. Up to about 6 “v-regions” can be used on each polypeptide chain. The v-regions of each polypeptide chain are connected linearly to one another and may be connected by interspersed linking regions. When arranged in the form of the PPC, the v-regions on each polypeptide chain form individual antigen binding sites.
