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 combination of linear polymers with dendritic chain-ends has led to numerous studies of linear-dendritic polymer hybrid materials. Interchain branching within the linear segment of these materials...
The periphery of hyperbranched polysaccharides has many end groups that can be functioned and used as sites to interact with their surroundings. A water-insoluble hyperbranched β-d-glucan, coded as T...
A new and general strategy for the synthesis of sequence-defined polymers is described that employs relay metathesis to promote the ring opening polymerization of unstrained macrocyclic structures. Ce...
How might fully saturated benzene polymers of composition [(CH)6]n form under high pressure? In the first approach to answering this question, we examine the step-wise increase in saturation of a one-...
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...
Incubator temperature is one of the most precious variables in IVF labs. When the IVF started, almost all incubator temperatures were set at 37 degrees which mimic in vivo conditions. Some...
The purpose of this study is to determine the extent to which Keramatrix dressing promotes the healing of second-degree burn wounds in pediatric patients.
Background: Local anaesthetic day-care open haemorrhoidectomy (LH) is feasible, cheap and may be the cost-effective surgical approach to third degree haemorrhoids. This prospective randomi...
Patients presenting for elective surgery requiring tracheal intubation will be randomized to one of two different ETT stylets. The primary outcome is time to intubation. The null hypothes...
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.
