Purpose: This retrospective study of patients with pulmonary arteriovenous malformations aims to assess the efficacy of embolization distal to the origin of the last normal branch of the pulmonary artery.
Material And Methods: A total of 30 consecutive patients with 38 untreated pulmonary arteriovenous malformations underwent coil embolization distal to the origin of the last normal branch of the pulmonary artery between September 2015 and October 2021. The median (interquartile range) age of patients (5 males, 25 females) was 59 years (50-68 years old), and the median (interquartile range) sizes of the feeding artery and sac were 2.
We investigate the adsorption behavior of polar and nonpolar molecules on carbon nanotube interfaces through computational simulations. Gaussian 16 was utilized to calculate the total energy of each possible molecular structure and analyze the adsorption mechanisms in stacked and inline configurations. The study reveals that nonpolar molecules favor stacked adsorption on two graphene interfaces, while polar molecules prefer inline adsorption.

Microbial biofuel cells (MiBFCs) are one such sustainable energy technology based electronic device which can not only harvest energy, but can perform biosensing leading to bioremediation. However, low energy yield, costly fabrication procedures and bulky devices are some of the limitations of such MiBFCs.

Systemic air embolism is a fatal lung biopsy complication, despite its low incidence. Incidental air immigration into the pulmonary vein passing through the left heart circulation results in air embolism in percutaneous lung biopsy. Herein, we report a 73-year-old man who presented with massive air collection in the left atrium after computed tomography-guided lung biopsy which resolved without any symptom.

There are various methods of thoracoscopic debridement under local anesthesia, although the optimal timing of treatment is unknown. The objective of this study was to verify the efficacy and safety of our video-assisted flexible thoracoscopic debridement (VAFTS-D) procedure under local anesthesia, and to investigate the clinical features associated with the success of VAFTS-D.

Carbon nanotubes were spin-coated onto a glass substrate, and subsequently, palladium nanoparticles were sputtered onto this film. The response to hydrogen gas was measured during two seasons (summer and winter) using a vacuum chamber by introducing a hydrogen/argon gas mixture.

Different concentrations of acetic acid were employed to investigate the effect of acetic acid on product yield and gas composition. The interaction between guaiacol and acetic acid during SCWG was discussed.

A 53-year-old man underwent surgical repair and drainage of a spontaneous esophageal rupture through a left anterolateral intercostal thoracotomy. Thereafter, wound infection persisted for 3 years with formation of cutaneous fistulae and granulation tissue. Chest computed tomography revealed osteolysis, swollen ribs and costal cartilage, and cutaneous fistulous tracts.

Case Presentation: A 43-year-old woman was referred with complaints of deteriorating dyspnea and orthopnea. Chest computed tomography revealed right massive pleural effusion and pericardial effusion.
Purposes: Acute exacerbation of interstitial pneumonia (AEIP) is a leading cause of death after lung cancer resection in patients with interstitial lung disease.
Methods: We retrospectively analyzed 1763 patients with non-small cell lung cancer with a clinical diagnosis of interstitial lung disease (ILD) who underwent lung cancer resection between 2000 and 2009 at 61 hospitals in Japan. AEIP occurred in 164 of 1763 (9.
Background: The interaction of vascular endothelial growth factor-C (VEGF-C)/VEGF-D/VEGF receptor-3 is considered to be a major driver of lymphangiogenesis, however the mechanism of this process remains unclear. We aimed to investigate the possible lymphangiogenic significance of synaptonemal complex protein 3 (SCP3) in non-small cell lung cancer (NSCLC).
Methods: The expression of SCP3, VEGF-C, and VEGF-D were measured and examined a correlation between SCP3 and VEGF-C or VEGF-D in various human lung cancer cell lines.
Pleural lavage has been considered a convenient and safe method that is often performed for empyema. We report a case of systemic air embolism that developed during pleural lavage. A 53-year-old man with empyema in the organizing phase suddenly developed paralysis of the left side of the body and altered level of consciousness during pleural lavage, which was performed in a sitting position without negative pressure suction.

Objective: The role of single-trocar thoracoscopy for complicated parapneumonic effusion (CPE) and pleural empyema is not established as yet. The aim of this study was to report our experience and analyze the efficacy and safety of debridement by single-trocar thoracoscopy for the patients with CPE and multiloculated empyema.
Methods: We performed a retrospective study reviewing the medical records of the patients treated parapneumonic effusion and multiloculated empyema by single-trocar thoracoscopy under local anesthesia at our department from January 2000 to December 2012.
Purpose: Nedaplatin is a cisplatin derivative, which has similar activity to cisplatin in non-small-cell lung cancer (NSCLC) when combined with vindesine, and causes less nausea/vomiting and nephrotoxicity compared with cisplatin. The aim of this study was to evaluate the efficacy and safety of combination chemotherapy with docetaxel plus nedaplatin in patients with metastatic NSCLC.
Methods: Patients with metastatic stage IIIB excluding locally advanced diseases or stage IV NSCLC were enrolled between March 2004 and March 2006.
Combined epidural and general anesthesia has become a standard anesthetic method for thymectomy. We employed levobupivacaine for epidural anesthesia combined with general anesthesia using remifentanil and sevoflurane for thymectomy with thoracoscopy for generalized type of myasthenia gravis. After decreasing the high level of antibodies to acethylcholine receptor by plasmapheresis, we could perform a stable and successful anesthetic management without the use of any muscle relaxants for the thymectomy.

The repair of photosystem II (PSII) after photodamage is particularly sensitive to oxidative stress and inhibition of such repair is associated with the oxidation of specific cysteine residues in elongation factor G (EF-G), a key translation factor, in the cyanobacterium Synechocystis sp. PCC 6803. Expression of mutated EF-G with a target cysteine residue replaced by serine in Synechocystis resulted in the protection of PSII from photoinhibition.
