We report a case of a pathological complete response (pCR) with chemotherapy for multiple huge liver metastases from colon cancer. A 59-year-old woman presented with anorexia and weight loss. Laboratory tests revealed elevated liver enzyme levels and tumor markers. A computed tomography/positron emission tomography-computed tomography scan revealed a transverse colon tumor and unresectable liver masses measuring 9.0 cm in maximum diameter in segments 7 and 8, with another mass in segment 6. She underwent laparoscopic colectomy and was administered FOLFOX + BV. After 11-cycles of chemotherapy, the liver masses became resectable with a partial response, so hepatectomy was performed. On the final histopathological analysis, all lesions were fibrotic without any viable cancer cells. The patient is alive without recurrence 2 years after resection. We believe this is the largest tumor of unresectable colorectal liver metastasis (CRLM) that has ever resulted in pCR with chemotherapy. FOLFOX + Bev was thus found to be an effective treatment for unresectable CRLM.

The intriguing way the receptors in biological skin encode the tactile data has inspired the development of electronic skins (e-skin) with brain-inspired or neuromorphic computing. Starting with local (near sensor) data processing, there is an inherent mechanism in play that helps to scale down the data. This is particularly attractive when one considers the huge data produced by large number of sensors expected in a large area e-skin such as the whole-body skin of a robot.

Adeno-associated virus (AAV) is a versatile viral vector technology that can be engineered for specific functionality in vaccine and gene therapy applications. One of the major challenges in AAV production is the need for a GMP-ready platform-based approach to downstream processing, as this would lead to a standardized method for multiple products. Chromatography has huge potential in AAV purification, as it is a scalable method that would enable manufacturing to a high degree of purity, potency, and consistency.

Parathyroid adenoma is the most common cause of primary hyperparathyroidism and rarely reaches huge sizes. As the gland enlarges it may exhibit atypical morphology and extension to the mediastinum which may complicate the excision of the tumor while preserving the capsular integrity. We present a 35-year-old male patient who was referred to our department with a complaint of severe hypercalcemia.

Identifying driver genes in cancer is a difficult task because of the heterogeneity of cancer as well as the complex interactions among genes. As sequencing data become more readily available, there is a growing need for detecting cancer driver genes based on statistical and mathematical modeling methods. Currently, plenty of driver gene identification algorithms have been published, but they fail to achieve consistent results.

Despite significant progress in wearable sensors, it is a significant challenge to monitor temperature and stress simultaneously with a single sensor. A wearable multifunctional optical sensor based on Er/Yb co-doped GdO nanoparticles and a tapered U-shaped fiber is proposed to monitor both temperature and stress in this paper.
