The remarkable properties of g.aphene have shown promise for new perspectives in future electronics, notably for nanometer scale devices. Here we g.ow g.aphene epitaxially on an off-axis 4H-SiC（0001） substrate and demonstrate the formation of periodic arrang.ment of monolayer g.aphene on planar （0001） terraces and Bernal bilayer g.aphene on （1120） nanofacets of SiC. We investig.te these lateral superlattices using.Raman spectroscopy, atomic force microscopy/ electrostatic force microscopy （AFM/EFM） and X-ray and ang.e resolved photoemission spectroscopy （XPS/ARPES）. The correlation of EFM and ARPES reveals the appearance of permanent electronic band g.ps in AB-stacked bilayer g.aphene on （1120） SiC nanofacets of 150 meV. This feature is confirmed by density functional theory （DFT） calculations. The charg. transfer between the substrate and g.aphene bilayer results in an asymmetric charg. distribution between the top and the bottom g.aphene layers opening.an energ. g.p. This surface org.nization can be thus defined as self-org.nized metal-semiconductor g.aphene.

Introduction: Pleomorphic adenoma or mixed salivary g.and tumor is a heterog.neous benig. tumor of the salivary g.ands. The most common site is the parotid g.and. Its extra-parotid locations, particularly in the accessory salivary g.ands, are rarer. We report a case of a pleomorphic adenoma of the posterior palate which posed manag.ment problems. Observation: This is an 85-year-old patient who consulted for a tumor of the posterior palate that had been evolving.for 3 years. The examination revealed a g.obular tumor of the posterior palate extending.beyond the midline by approximately 7 cm in long.axis, shooting.towards the oropharynx and hindering.breathing. speech and eating. indicating.a life-saving.tracheotomy. A CT scan of the facial area revealed a well-circumscribed tumor at the expense of the soft palate, with multiple sites of bone lysis. The biopsy performed was in favor of a pleomorphic adenoma. The patient underwent total surg.cal excision of a hug. tumor on the palate. The aftermath of the operation was marked by a loosening.of the sutures with an oronasal fistula requiring.the creation of an obturator plate due to the patient’s refusal to have another operation. Conclusion: Larg. pleomorphic adenoma of the posterior palate is a rare entity that can cause respiratory problems and surg.cal difficulties. His prog.osis is g.nerally g.od.

Cancers of the lip are the leading.cause of labial defects, and treatment is essentially surg.cal. The success of a repair is assessed by two essential criteria: The functional character of the lip (restoration of continence allowing.feeding. and the aesthetic quality of the repair. However, for many patients from countries whose medical infrastructure does not allow them to undertake complex reconstructions locally, medical transfers represent their only chance of treatment. The aim of this article is to share with you an extreme clinical case of labial reconstruction, the manag.ment of which was a real challeng., using.two major flaps: the free ante-brachial flap and the DUFOURMENTEL-type bi-pediculated scalp flap.

Introduction: Squamous cell carcinomas of the lip essentially pose a therapeutic manag.ment problem. In the West, their treatment is done under g.neral anesthesia and follows the classic rules of oncolog.. In our context of exercise, we sometimes have a different attitude dictated by various constraints. Observation: 55-year-old patient with no notable history, seen in consultation for a very larg. ulcerative-budding.lesion on the rig.t 2/3 of the lower lip with mucocutaneous involvement without lymph node finding. found on examination. Faced with this suspicious lesion and the patient’s financial difficulties, we decided to operate under local anesthesia to remove this tumor. The oncolog.cal excision was followed by immediate plasty using.a Camille-Bernard flap with a g.od immediate aesthetic and functional result and postoperative day 7. The patient was unable to take his surg.cal specimen to anatomy-patholog. and was lost to follow-up due to lack of financial resources. On anatomo-patholog.cal analysis of the surg.cal specimen, the marg.ns were healthy with confirmation of squamous cell carcinoma (anapatholog.cal reading.made for scientific interest). Discussion: The particular mentality of certain patients and their difficult financial conditions push us to have an unconventional therapeutic attitude in oncolog., but which nevertheless makes it possible to resolve certain problems that we often face. Local anesthesia is possible and realistic in cases like ours and the results can be acceptable and life-saving.

Oral cavity cancers are part of head and neck cancers. They have become frequent in the world in g.neral and Seneg.l in particular. This study evaluates microsatellite instability tumors in oral cavity cancers in Seneg.l. Forty cancerous tissues, 20 healthy tissues, and 12 blood tissues were included in this study. These tissues were collected from each patient during.the biopsy after obtaining.consent. DNA extraction, Polymerase Chain Reaction (PCR) and sequencing.were carried out to obtain sequences. Mutation surveyor, Bioedit and Dnasp software were used to perform our analyses. Hig. instability was found in 57.5% of patients with cancer. Moreover, 90% of the patients had the same motif on healthy and cancerous tissue. Furthermore, 26.12%, 20.72%, and 11.71% polymorphic sites were found in cancerous, healthy and blood tissue respectively. Thus, a similarity between cancerous and healthy tissues seems to exist. This implies that instability of the Bat 26 microsatellite could occur early in the occurrence of oral cavity cancers.

We analyze the statistical properties of the photons emitted at the junction of a scanning.tunneling.microscope at the solid/liquid interface by time-autocorrelated two-photon counting.measurements, with time resolutions down to the nanosecond scale. In the case of a g.ld-g.ld junction immersed in an inhomog.neous liquid, we show that the tip-induced luminescence exhibits a clear bunching.phenomenon depending.on the tip-sample distance.
