The design, synthesis, and investigation of antitumor and anti-lipase activities of some coumarin-triazole hybrid molecules are reported. The synthesis of these hybrid molecules was performed under microwave irradiation and conventional heating procedures. The newly synthesized hybrid molecules were investigated as inhibitors against four tumor cell lines (BT20 human breast carcinoma, SK-Mel 128 melanoma, DU-145 prostate carcinoma, and A549 lung carcinoma) and porcine pancreatic lipase (PPL). Most of these compounds showed notable antitumor activities against the tested tumor cell lines, and compounds 8i and 8l showed the best anti-lipase activity of 99...

Background Image-guided thermal ablation can be used for the treatment of medically inoperable primary and metastatic lung cancer. These techniques are based on the heating up or freezing (cryoablation) of a volume of tissue around a percutaneous applicator that induces necrosis of the tumor. Method The English-language literature concerning thermal ablation of the lung was reviewed. Radiofrequency ablation (RFA) is the most widely performed and investigated of these techniques. Microwave ablation (MWA) represents a relatively new alternative that shares the same indications and is conducted in a very similar fashion as RFA...

REVIEW
Jacob A Klapper, Scott A Hittinger, Chadrick E Denlinger
The standard of care for the surgical management of non-small cell lung cancer remains a lobectomy. For patients with limited pulmonary reserve, lesser resections or nonoperative therapies may be indicated. The purpose of this review is to evaluate the outcomes from more limited resections as well as the evidence for the efficacy of photon-based and proton-based stereotactic body radiotherapy, radiofrequency ablation, and microwave thermal ablation. In doing so, the goal of this review is to provide surgeons with an evidence-based treatment menu for treating patients who are not candidates for lobectomy...

Thoracic fluid accumulation is one of the significant and early-stage manifestations of fatal diseases, such as lung-cancer, liver-failure and congestive heart-failure. Currently, computational-tomography (CT)-Scan is the most widely used tool for the detection of thoracic fluid. Yet, it is unable to detect small amounts of fluid, has ionizing radiation and lacks mobility. On the other hand, microwave imaging systems have emerged as an accurate and portable complementary diagnostic tool. However, there is a lack of a complete clinical platform that can fulfill the requirements of accurate and reliable imaging...

BACKGROUND: Microwave ablation has been extensively used for eliminating pulmonary tumors; however, it is usually associated with severe pain under local anesthesia. Decreasing the power and shortening the ablation time can help to relieve the pain; however, this leads to incomplete ablation and an increasing recurrence rate. This research aims to employ an artificial pneumothorax to increase both the curative effect and pain relief during the ablation procedure. MATERIAL AND METHODS: From July 2013 to January 2015, nine patients presenting with 10 subpleural lung tumors (age: 44-78 years) with a high possibility of severe pain underwent the artificial pneumothorax during microwave ablation...

Bronchiolitis obliterans (BO) is an increasingly important lung disease characterized by fibroproliferative airway lesions and decrements in lung function. Occupational exposure to the artificial food flavoring ingredient diacetyl, commonly used to impart a buttery flavor to microwave popcorn, has been associated with BO development. In the occupational setting, diacetyl vapor is first encountered by the airway epithelium. To better understand the effects of diacetyl vapor on the airway epithelium we used an unbiased proteomic approach to characterize both the apical and basolateral secretomes of air liquid interface cultures of primary human airway epithelial cells from four unique donors after exposure to an occupationally relevant ~1100 ppm of diacetyl vapor or PBS as a control on alternating days...

The European Society for Medical Oncology (ESMO) have stressed that the option for treating oligometastatic disease is a strategy of local ablative therapy, the goal of which is to improve disease control. The spectrum of the local ablative therapy toolbox described by the ESMO includes surgical R0 resection, percutaneous ablation and intra-arterial therapies, the choice of treatment being left to the multidisciplinary team. Interventional therapy involving image-guided treatment offers the possibility of less invasive treatments for colorectal cancer metastases in the liver, lung and bone by preserving from toxicity distant healthy organs or even parts of the diseased organs...
