In this article, we discuss how the improvement of culinary techniques with the dissemination of knowledge about meat preparation conditions is an effective strategy for reducing the formation and ingestion of HAs and PAHs; this is important due to the growing evidence about the association between meat consumption and chronic diseases. see more This is the first systematic review with meta-analysis about this topic and can guide industry, food services, and population to improve the safety associated with meat consumption.Margin status is one of the significant prognostic factors for recurrence in breast-conserving surgery (BCS). The issue that merits consideration for oncologic safety and cost-effectiveness about the modalities to assure clear margins at initial surgical intervention remains controversial after neo-adjuvant chemotherapy (NAC). The presented study aimed to assess the impact of intraoperative ultrasound (IOUS)-guided surgery on accurate localization of tumor site, adequacy of excision with clear margins, and healthy tissue sacrifice in BCS after NAC. Patients who had IOUS-guided BCS ater NAC were reviewed. No patient had preoperative localization with wire or radiotracer. Intraoperative real-time sonographic localization, sonographic margin assessment during resection, macroscopic and sonographic examination of specimen, and cavity shavings (CS) were done as the standard procedure. No frozen assessment was performed. One hundred ninety-four patients were included, in which 42.5% had pCR. IOUS-guided surgery accomplished successful localization of the targeted lesions in all patients. Per protocol, all inked margins on CS specimens were reported to be tumor-free in permanent histopathology. No re-excision or mastectomy was required. For a setting without CS, the negative predictive value (NPV) of IOUS rate was 96%. IOUS was found to over and underestimate tumor response to NAC both in 2% of patients. IOUS-guided surgery seems to be an efficient modality to perform adequate BCS after NAC with no additional localization method. Especially, when CS is integrated as a standard to BCS, IOUS seems to provide safe surgery for patients with no false negativity and a high rate of NPV.The use of functionalized aldimines has been demonstrated as newly structural 1,4-dipole precursors under carbene catalysis. More importantly, enantiodivergent organocatalysis has been successfully developed using carbene catalysts with the same absolute configuration, leading to both (R)- and (S)- enantiomers of six-membered heterocycles with quaternary carbon centers. This strategy features a broad substrate scope, mild reaction conditions, and good enantiomeric ratio. DFT calculation results indicated that hydrogen bond C-H⋅⋅⋅F interactions between the catalyst and substrate are the key factors for controlling and even switching the enantioselectivity. These new 1,4-dipoles can also react with isatin and its imines under carbene catalysis, allowing for access to the spiro oxindoles with excellent enantiomeric ratios.
Purpose of the article is to discuss the use of the scapular tip free flap (STFF) for the reconstruction of maxillary defects.

A retrospective evaluation of patients who underwent maxillary reconstruction with STFF is presented. Patients were evaluated with respect to complications, function, and cosmesis.

Study population consisted of 53 patients. All flaps survived and partial bone resorption only occurred in a young patient. Minor complications included two instances of partial muscular necrosis. The donor site was primarily closed in all patients. Mouth opening was assessed as good (>3 cm) in 41 patients, partially limited (2-3 cm) in 9 patients, and limited (<2 cm) in 3 patients. Dental rehabilitation was achieved in 35 patients; esthetic results were assessed by patient as excellent in 19 patients, good in 28 patients, and poor in 6 patients.

The scapular tip chimeric free flap represents an indispensable tool for reconstructive head and neck microsurgery. The main advantages of this technique are very low donor site morbidity and a long pedicle, as well as the potential for harvesting multiple flaps in a chimeric design; STFF represents the first choice for treatment of small postero-lateral defects of the maxilla, and of wide and complex through-and-through defects involving all components of the midface.

Antiresorptive treatment has been shown to impair mucosal cell proliferation, migration, and viability. However, in the clinic, antiresorptives are often used in combination with other drugs. We studied the effect of antiresorptives combined with a corticosteroid or antiestrogen on oral mucosal keratinocytes and fibroblasts.

Human gingival keratinocyte and fibroblast cell lines were exposed to bisphosphonates (BPs) and denosumab in different concentrations and durations together with an antiestrogen or corticosteroid. Changes in cell viability, proliferation and migration after exposures were measured. Data were evaluated with hierarchical linear mixed model for repeated measurements.

Bisphosphonate exposure suppressed keratinocyte and fibroblast cell viability, proliferation, and migration in a time-dependent manner. Combining a corticosteroid or antiestrogen with BPs further increased this negative effect. Denosumab alone had a mild positive effect on keratinocyte and fibroblast growth. When denosumab was combined with a corticosteroid or antiestrogen, cell growth was suppressed.

Our results show that coexisting medications may increase the negative impact of BPs or denosumab on oral mucosal cells.
