Contralateral submental artery island flap for oral tongue reconstruction - a retrospective study in patients with oral tongue squamous cell carcinoma.

Background: Oral squamous cell carcinoma (OSCC) is a leading cause of cancer-related deaths in developing countries. The oral tongue is the most common site involved by OSCC. About one-third of the patients have neck nodal metastasis at presentation.

Definitive Surgery after Neoadjuvant Chemotherapy for Locally Advanced Oral Cavity Cancers: Experience from a Tertiary Care Center.

Mansi AgrawalVidya Konduru  Oral cavity cancers require definitive surgical resection as the primary treatment, but with advanced T stage, complete resection with pathologically negative margins might be difficult to achieve. Induction chemotherapy helps achieve the balance between resection and morbidity in locally advanced technically unresectable tumors. The aim of this study was to analyze the impact of surgery in locally advanced, technically unresectable oral cavity cancers after neoadjuvant chemotherapy (NACT).

Free convective oscillatory flow due to inclined perpendicular shield subject to the thermos-diffusion and suction effects.

An unsteady free convective flow of an electrically conducting viscous fluid due to accelerated inestimable inclined perpendicular shield has been presented in presence of heat and mass transfer phenomenon. The applications of thermos-diffusion and heat source are also incorporated. The chemical reaction consequences are considered in the concentration equation.

The folded, bipaddled pectoralis major myocutaneous flap for complex oral cavity defects: Undiminished relevance in the era of free flaps.

Oral cancer often presents at an advanced stage, requiring extensive resection and complex reconstruction, such as free tissue transfers, which may not be available in a remote or resource-constrained facility. The common alternative in these cases is the use of the workhorse flap, the pectoralis major myocutaneous (PMMC) flap for lining and a second regional flap for cover. The results are variable, increase operative time and cost, and may cause additional donor site morbidity.

A New Experiment for Investigating Evaporation and Condensation of Cryogenic Propellants.

Passive and active technologies have been used to control propellant boil-off, but the current state of understanding of cryogenic evaporation and condensation in microgravity is insufficient for designing large cryogenic depots critical to the long-term space exploration missions. One of the key factors limiting the ability to design such systems is the uncertainty in the accommodation coefficients (evaporation and condensation), which are inputs for kinetic modeling of phase change. A novel, combined experimental and computational approach is being used to determine the accommodation coefficients for liquid hydrogen and liquid methane.
