Impacted supernumerary tooth in the horizontal plate of palatine bone: a rare case report.

Background: Supernumerary teeth, defined as extra teeth beyond the normal series of dentition, can appear anywhere in the dental arch. They may present as solitary or multiple, unilateral or bilateral, and can be either erupted or impacted. Rarely, supernumerary teeth are found in ectopic locations outside the dental arches, such as the nasal cavity, inferior nasal conchae, maxillary sinus, ethmoid sinus, or skull.

Financial Barriers to Rural Graduate Medical Education: Medicare Funding Methods for Sole Community and Medicare-Dependent Hospitals.

Purpose: Policymakers are exploring options to address rural-urban physician maldistribution, including reducing rural residency training barriers. This study estimated Medicare graduate medical education (GME) reimbursement that sole community hospitals (SCHs) and Medicare-dependent hospitals (MDHs) are disqualified from receiving compared with hospitals under the Prospective Payment System (PPS) and calculated the GME reimbursement per resident for MDHs and SCHs under different scenarios.

Method: This simulation study used Healthcare Cost Report Information System data on hospitals that had been SCHs or MDHs between 2011 and 2021 and did not have any resident full-time equivalents (FTEs) in the most recent year.

Electric stimulation: a versatile manipulation technique mediated microbial applications.

Electric stimulation (ES) is a versatile technique that uses an electric field to manipulate microorganisms individually. Over the past several decades, the capabilities of ES have expanded from bioremediation to the precise motion control of cells and microorganisms. However, there is limited information on the underlying mechanisms, latest advancement and broader microbial applications of ES in various fields, such as the production of extracellular polymers with upgraded properties.

Schwannoma of the Soft Palate: A Rare Case Report.

Oral schwannomas are rare, with only 18 cases of soft palate involvement reported since 1985. We report a case of a 15-year-old male with a soft palate schwannoma who was successfully treated by surgical excision and had no complications over a one-year follow-up. Histologically, schwannomas exhibit Antoni A and B patterns.

Borenium Ion Equivalents Stabilized by BICAAC and Their Implementation as Catalysts in Hydrosilylation of Carbonyls.

Hydride abstraction from the borane adduct, (BICAAC) ⋅ BH afforded the hydride bridged dinuclear borenium ion equivalent complexes 1 and 2 that have been characterized by various spectroscopic and spectrometric techniques followed by the assessment of Lewis acidity using the Gutmann-Beckett method. The single crystal X-ray structure of complex 2 revealed the presence of discrete ions in the solid state. The complex (BICAAC) ⋅ BH(OTf) (3), obtained from the reaction of (BICAAC) ⋅ BH with MeOTf, formed the corresponding boronium cations [(BICAAC) ⋅ BH(L)](OTf) on reaction with Lewis bases (L= pyridine (4) and DMAP (5)).
