Intraoral anastomosis technique as part of the reconstruction strategy following resection of intermediate and low-grade head and neck cancer.

Introduction: The gold standard for curative treatment of facial, oral, nasal, paranasal and pharyngeal cancers is excision and reconstruction surgery. Patients are increasingly demanding carcinologically effective and minimally invasive surgery with near ad integrum functional and aesthetic reconstruction. In malignant tumors with no indication for lymph node dissection, when the defect size dictates free flap reconstruction, the intrabuccal anastomosis technique comes closest to meeting these requirements.

Reticulated livedoid skin patterns after soft-tissue filler-related vascular adverse events.

Background: For the treatment of vascular adverse events caused by filler injections, duplex ultrasound imaging may be used. The findings of duplex ultrasound examination and the clinical features of reticulated livedoid skin patterns were compared with the hemifaces anatomy.

Objective: The objective of this study was to link the reticulated livedoid skin patterns to the corresponding duplex ultrasound findings and the facial perforasomes.

Skin Perfusion After Hemostatic Net: An Anatomic and Radiologic Study in a Cadaver Model.

Background: The hemostatic net is a recent technique initially developed to reduce the occurrence of postoperative hematomas following facelift procedures. Its applications have expanded to include skin redraping, deep plane fixation, and other areas beyond the face. However, no experimental study has investigated its effect on skin blood supply.

Adiabatic Invariant of Center-of-Mass Motion during Walking as a Dynamical Stability Constraint on Stride Interval Variability and Predictability.

Human walking exhibits properties of global stability, and local dynamic variability, predictability, and complexity. Global stability is typically assessed by quantifying the whole-body center-of-mass motion while local dynamic variability, predictability, and complexity are assessed using the stride interval. Recent arguments from general mechanics suggest that the global stability of gait can be assessed with adiabatic invariants, i.

[Pasteurellosis breast implant infection: A case report and literature review].

Breast implant infection is a potential complication after surgery. This case reports an unusual infection. A patient undergoes a skin sparing mastectomy for a carcinoma with an immediate breast implant reconstruction.

Optimization and validation of extraction and quantification methods of antimalarial triterpenic esters in Keetia leucantha plant and plasma.

The aim of this study is to develop validated methods for the extraction and quantification of antimalarial triterpene esters from Keetia leucantha and from plasma samples. These compounds, showing in vitro and in vivo antiplasmodial activities, were optimally extracted from Keetia leucantha twigs using ultrasounds with dichloromethane and from plasma using protein precipitation with acetonitrile. We then developed and validated HPLC-UV quantification methods, which proved to be selective, accurate, linear, true and precise, both in plant and plasma samples for the eight triterpenic esters in mixture.

Plant defense stimulation by natural isolates of bacillus depends on efficient surfactin production.

Some plant-associated Bacillus strains produce induced systemic resistance (ISR) in the host, which contributes to their protective effect against phytopathogens. Little is known about the variety of elicitors responsible for ISR that are produced by Bacillus strains. Working with a particular strain, we have previously identified the surfactin lipopeptide as a main compound stimulating plant immune-related responses.

The bacterial lipopeptide surfactin targets the lipid fraction of the plant plasma membrane to trigger immune-related defence responses.

The lipopeptide surfactin secreted by plant-beneficial bacilli has crucial biological functions among which the ability to stimulate immune-related responses in host tissues. This phenomenon is important for biological control of plant diseases but its molecular basis is still poorly understood. In this work, we used various approaches to study the mechanism governing the perception of this biosurfactant at the plant cell surface.
