Passing The Scalpel: A Student Initiative in Identifying and Addressing Unmet Needs in Dental Education.

Purpose: Becoming an oral-maxillofacial surgeon is often challenging for young trainees. The purpose of this manuscript is to explore how a student-led group, which emphasizes networking, mentorship, and academic opportunities, may impact one's journey to becoming an oral-maxillofacial surgeon.

Patients And Methods: This was a cross-sectional descriptive study where a 5-question Likert-type survey was administered to students who matriculated into residency and participated in a student-led group called Passing The Scalpel (PTS).

Successive Reimplantation of Dental Implants Into Sites of Previous Failure.

Purpose: To evaluate the survival rates of dental implants that had been reimplanted in sites of previous failure, including first, second, and third reimplantations, and investigate the various factors that could affect the reimplantation outcomes.

Materials And Methods: All dental implants placed in sites of previous implant failure were identified, including first, second, and third reimplantations. The survival rates were assessed, and epidemiologic and clinical data were collected and analyzed to evaluate the effects on reimplantation survival.

The effect of α-mating factor secretion signal mutations on recombinant protein expression in Pichia pastoris.

The methylotrophic yeast, Pichia pastoris, has been genetically engineered to produce many heterologous proteins for industrial and research purposes. In order to secrete proteins for easier purification from the extracellular medium, the coding sequence of recombinant proteins is initially fused to the Saccharomyces cerevisiae α-mating factor secretion signal leader. Extensive site-directed mutagenesis of the prepro-region of the α-mating factor secretion signal sequence was performed in order to determine the effects of various deletions and substitutions on expression.

Conserved C-terminal domain of spider tubuliform spidroin 1 contributes to extensibility in synthetic fibers.

Spider silk is renowned for its extraordinary mechanical properties, having a balance of high tensile strength and extensibility. To date, the majority of studies have focused on the production of dragline silks from synthetic spider silk gene products. Here we report the first mechanical analysis of synthetic egg case silk fibers spun from the Latrodectus hesperus tubuliform silk proteins, TuSp1 and ECP-2.
