Basal cell carcinoma of the nose tip: A case report of precision surgery and local flap reconstruction.

Introduction And Importance: Basal cell carcinoma is the most common non-melanoma skin cancer, tightly connected to ultraviolet exposure, and typically occurs on sun-exposed areas, including the nose. Reconstructing defects in the nasal tip following the removal of basal cell carcinoma lesions presents significant challenges, requiring a balance between completely removing the cancerous cells and achieving an optimal aesthetic result, especially since this area is central to the face.

Case Presentation: We present the case of a 62-year-old male patient with a 2 × 3 cm tumor located at the nasal tip, initially diagnosed as a benign vascular tumor based on clinical examination and imaging results.

Cost-related medication nonadherence in the Mekong Delta, Vietnam.

Association of testicular histopathology with sperm retrieval success rates in men with idiopathic non-obstructive azoospermia.

Introduction: Infertility is a major public health issue, with male factors alone contributing to 20-30% of cases. Non-obstructive azoospermia (NOA) is the most severe form, and although techniques like microdissection testicular sperm extraction (mTESE) offer hope, it remains challenging due to its uncertain causes. This study investigates the correlation between testicular histopathology and clinical parameters to enhance sperm retrieval (SR) prediction.

A design TCADAS tool for semiconductor devices and case study of 65 nm conventional floating-gate MOS transistor.

An automatic programming tool has become an essential component in virtual fabrication in recent years. This paper aims to propose a methodology of virtual fabrication for semiconductor devices and design a tool called Technology Computer-Aided Design Automatic Simulation (TCADAS) which can perform a completely virtual fabrication, device simulation, process variation, and output extraction. Especially, the TCADAS tool eliminates drudgery when studying semiconductor devices such as complexity in setting inputs, substantial manual work, and long run time of simulations.

Sensitivity analysis and thermodynamic evaluation of a combined cooling, heating and power system utilizing exhaust gases of smelting furnace.

Exhaust gases from the smelting furnace have high temperature and mass flow rate, and there is huge potential to use them for energy-related purposes such as electricity generation, cooling and heating. Utilization of the gases for energy-related purposes would lead to fuel savings and emissions reduction. To use this potential, it is necessary to design proper systems and cycles and apply a heat recovery unit.

Underwater Versus Conventional Endoscopic Mucosal Resection for Colorectal Laterally Spreading Tumors: A Post Hoc Analysis of Efficacy.

Background And Aims: Underwater endoscopic mucosal resection (UEMR) has emerged as a promising alternative to conventional endoscopic mucosal resection (CEMR) for the treatment of colorectal laterally spreading tumors (LSTs). This study aimed to compare the efficacy and safety of UEMR and CEMR in managing LSTs measuring 10-30 mm.

A New Generation of Multimilliwatt-Class Colloidal Quantum-Dot Lasers at Full Colors.

Colloidal quantum dots (QDs) are attractive gain materials owing to the wide range of accessible colors. However, the existing QD lasers struggle to combine technologically relevant metrics of low threshold and long operating duration with considerable output powers. Here a new class of full-color QD lasers are reported, featuring low threshold, uninterrupted operation for dozens of hours, and multimilliwatt output under quasi-steady-state pumping, by coupling the high-gain QDs with a double-clad pumping scheme.
