A linear polymer, hyperbranched polymers with various degrees of branching, and 100% hyperbranched polymers were successfully synthesized by self-polycondensation of 2,2,2-trifluoro-1-[4-(4-phenoxyphenoxy)phenyl]ethanone by using different amounts of trifluoromethanesulfonic acid from the same AB(2) monomer.

The therapeutic potential of hyperbranched polymers targeted to prostate cancer and loaded with doxorubicin was investigated. Polyethylene glycol hyperbranched polymers were synthesised via RAFT polym...
The surfactants of the linear-hyperbranched phosphate esters (PAMAMGn-3-Ps) have been constructed through random multibranching esterification of lauroyl chloride and phosphate ester as a branching ag...
Hybrids that are molecular scale co-networks of organic and inorganic components are promising biomaterials, improving the brittleness of bioactive glass and the strength of polymers. Methacrylate pol...
Randomly branched polymer chains (or trees) are a classical subject of polymer physics with connections to the theory of magnetic systems, percolation and critical phenomena. More recently, the model ...
We report two hyperbranched conjugated polymers (HCP) with truxene units as core and 1,4-didodecyl-2,5-diethynylbenzene as well as 1,4-bis(dodecyloxy)-2,5-diethynyl¬benzene as co-monomers. Two analog...
Although salivary contents play a major role in the early stage of food digestion process, their role in taste perception of glucose polymers is essentially unknown. It is hypothesized tha...
In approximately half of individuals with Down syndrome, an higher than normal number of vessels cross the optic disc margin. Investigator hypothesize that early retinal vessel branching o...
The overall aim of the study is to construct a scale that systematically incorporates the callers' perspective in a "degree of worry - scale" and to explore the consequences for the actors...
Treatment strategies of II. degree burn wounds and split-skin grafted III. degree burn wounds aim at reducing infection and improving reepithelialization. The aim of this study is to evalu...
Randomized Controlled Trial of the Effectiveness of Perineal Pain and Security of the Suture Led by the Result of Hemostasis Versus Manual Compression Routine Suture Perineal Tears of First Degree During Childbirth
During childbirth, the recommendations have evolved to a restriction of episiotomy. This reduction results in an increase of superficial vaginal and perineal tears. These lesions are usual...
A family of RNA viruses, of the order MONONEGAVIRALES, containing filamentous virions. Although they resemble RHABDOVIRIDAE in possessing helical nucleocapsids, Filoviridae differ in the length and degree of branching in their virions. There are two genera: EBOLAVIRUS and MARBURGVIRUS.
The total area or space visible in a person's peripheral vision with the eye looking straightforward. The average extent is about 65 degree upward, 75 degree downward, 60 degree inward, and 95 degree outward. Visual fields can be measured by PERIMETRY.
Derivatives and polymers of styrene. They are used in the manufacturing of synthetic rubber, plastics, and resins. Some of the polymers form the skeletal structures for ion exchange resin beads.
Implanted fluid propulsion systems with self-contained power source for providing long-term controlled-rate delivery of drugs such as chemotherapeutic agents or analgesics. Delivery rate may be externally controlled or osmotically or peristatically controlled with the aid of transcutaneous monitoring.
Educational programs for pharmacists who have a bachelor's degree or a Doctor of Pharmacy degree entering a specific field of pharmacy. They may lead to an advanced degree.
