Loss of JCAD/KIAA1462 Protects the Lung from Acute and Chronic Consequences of Chronic Obstructive Pulmonary Disease.

Even with recent advances in pathobiology and treatment options, chronic obstructive pulmonary disease (COPD) remains a major contributor to morbidity and mortality. To develop new ways of combating this disease, breakthroughs in our understanding of its mechanisms are sorely needed. Investigating the involvement of underanalyzed lung cell types, such as endothelial cells (ECs), is one way to further our understanding of COPD.

Randomized single-blind comparative study of the midazolam/pethidine combination and midazolam alone during bronchoscopy.

Background: Bronchoscopy can be a distress for the patient. There have been few studies on the combination of sedatives and opioids. The aim of this study was to demonstrate the usefulness and safety of administration of the combination of midazolam and pethidine during bronchoscopy.

Annexin A10 Expression as a Novel Prognostic Marker in Lung Adenocarcinoma.

Background/aim: Annexin A10 (ANXA10) is a member of the annexin family and a calcium-dependent phospholipid-binding protein. The aim of this study was to clarify the clinical significance of ANXA10 expression in lung adenocarcinoma.

Materials And Methods: ANXA10 expression was immunohistochemically examined in surgical specimens of lung adenocarcinoma obtained from 74 consecutive patients who underwent complete resection from January 2014 to December 2014.

[A Case of Multiple Brain Tumors Successfully Diagnosed with Liquid Biopsy and Treated with Osimertinib].

A seventy‒year‒old man complaining of left arm weakness and gait disturbance was diagnosed with multiple tumors and severe edema in the brain as well as right lung mass lesion, suggesting brain metastases. He started whole brain radiation therapy but had to discontinue it since his neurological symptoms were worsened including paralysis, aphasia, and coma. These symptoms made it difficult to perform tumor biopsy for cancer diagnosis as well as oncogene mutations.

Crystalline and Electrical Property Improvement of Filtrated, Exfoliated Graphite Sheets by an In-Plane Current and Heating Treatment.

We report an approach to fabricate high conductivity graphite sheets based on a heat-and-current treatment of filtrated, exfoliated graphite flakes. This treatment combines heating (~ 900 °C) and in-plane electrical current flow (550 A·cm) to improve electrical conductivity through the reduction of crystalline defects. This process was shown to require only a 1-min treatment time, which resulted in a 2.

Novel Multitarget Therapies for Lung Cancer and Respiratory Disease.

In recent years, multitarget drugs for neurological diseases such as Alzheimer's disease have been developed and well researched. Many studies have revealed that multitarget drugs are also useful for lung cancer and respiratory diseases. Pemetrexed is a multitargeted antifolate with strong antitumor activity against mesothelioma and lung adenocarcinoma.

Feasibility Study of Adjuvant Chemotherapy with Carboplatin and Nab-Paclitaxel for Completely Resected NSCLC.

Purpose: Adjuvant chemotherapy with cisplatin (CDDP) plus vinorelbine is the standard regimen for the treatment of non-small cell lung cancer (NSCLC). However, CDDP elicits severe toxic effects, including emesis, neurotoxicity, and renal damage; carboplatin (CBDCA) may be a feasible alternative for CDDP-unfit patients. CBDCA plus paclitaxel (PTX) adjuvant chemotherapy showed a survival benefit for patients with stage IB tumors >4 cm in size, while CBDCA plus nanoparticle albumin-bound (nab)-PTX showed greater efficacy and lower neurotoxicity than CBDCA plus PTX in advanced NSCLC.

Non-parallel anti-tumour effects of pembrolizumab: a case of cardial tamponade.

We present the case of a 70-year-old man with stage IV lung adenocarcinoma. He was treated with pembrolizumab, a programmed cell death-1 (PD-1) inhibitor, as a first-line therapy. After six cycles of pembrolizumab, he suddenly developed cardiac tamponade.

Microscopic polyangiitis presented with biopsy-confirmed pleuritis.

We describe a case of microscopic polyangiitis manifested as pleuritis confirmed by thoracoscopic biopsy. An 80-year-old man presented with a three-day history of shortness of breath and cough. Chest radiography revealed patchy opacities in the lower fields of the bilateral lung and right-sided pleural effusion.

Combinatorial selection for replicable RNA by Qβ replicase while maintaining encoded gene function.

Construction of a complex artificial self-replication system is challenging in the field of in vitro synthetic biology. Recently, we developed a translation-coupled RNA replication system, wherein an artificial genomic RNA replicates with the Qβ RNA replicase gene encoded on itself. The challenge is to introduce additional genes into the RNA to develop a complex system that mimics natural living systems.

A sweet spot for highly efficient growth of vertically aligned single-walled carbon nanotube forests enabling their unique structures and properties.

We investigated the correlation between growth efficiency and structural parameters of single-walled carbon nanotube (SWCNT) forests and report the existence of a SWCNT "sweet spot" in the CNT diameter and spacing domain for highly efficient synthesis. Only within this region could SWCNTs be grown efficiently. Through the investigation of the growth rates for ∼340 CNT forests spanning diameters from 1.

The Application of Gas Dwell Time Control for Rapid Single Wall Carbon Nanotube Forest Synthesis to Acetylene Feedstock.

One aspect of carbon nanotube (CNT) synthesis that remains an obstacle to realize industrial mass production is the growth efficiency. Many approaches have been reported to improve the efficiency, either by lengthening the catalyst lifetime or by increasing the growth rate. We investigated the applicability of dwell time and carbon flux control to optimize yield, growth rate, and catalyst lifetime of water-assisted chemical vapor deposition of single-walled carbon nanotube (SWCNT) forests using acetylene as a carbon feedstock.

Scalability of the Heat and Current Treatment on SWCNTs to Improve their Crystallinity and Thermal and Electrical Conductivities.

We have investigated the scalability of our post-synthesis graphitization process for single-walled carbon nanotubes (SWCNTs), which applies heat and current to SWCNTs to improve the thermal and electrical conductivities. This investigation was performed by examining the relationship between the processing conditions and the amount of treated SWCNTs. Characterization of all cases of treated SWCNTs showed the same level of improvement of ~3 times to both the thermal and electrical conductivities and that the SWCNTs remained SWCNTs, i.

The relationship between the growth rate and the lifetime in carbon nanotube synthesis.

We report an inverse relationship between the carbon nanotube (CNT) growth rate and the catalyst lifetime by investigating the dependence of growth kinetics for ∼330 CNT forests on the carbon feedstock, carbon concentration, and growth temperature. We found that the increased growth temperature led to increased CNT growth rate and shortened catalyst lifetime for all carbon feedstocks, following an inverse relationship of a fairly constant maximum height. For the increased carbon concentration, the carbon feedstocks fell into two groups where ethylene/butane showed an increased/decreased growth rate and a decreased/increased lifetime indicating different rate-limiting growth processes.

Current treatment of bulk single walled carbon nanotubes to heal defects without structural change for increased electrical and thermal conductivities.

By applying electrical current with heat, we succeeded in improving the graphitization of single walled carbon nanotubes (SWCNTs) without increasing the diameter and wall number. At 800 °C, 150 A cm(-2) (1150 W cm(-2)) for 1 min, we achieved a 3.2-times increase in the Raman G- to D-band ratio, a 3.

Quantitative assessment of the effect of purity on the properties of single wall carbon nanotubes.

We quantitatively demonstrate the importance of high purity for the application of single wall carbon nanotubes (SWCNTs), materials solely composed of one surface, by examining the effects of carbon impurities on the electrical, thermal, and mechanical properties of both as-grown SWCNT forests and processed buckypaper. While decreases in properties were expected, our results showed the extreme sensitivity of SWCNT properties to carbonaceous impurities either through scattering in the individual SWCNTs or an inhibition of the ability to form inter-SWCNT junctions. Each property showed a nonlinear decrease (as high as 40%) with the addition of low levels of carbon impurities (∼15 wt%), which demonstrates that purity is as important as the crystalline structure.

Electrostatic flocking is applied to create an array of aligned carbon fibers from which an elastomeric thermal interface material (TIM) can be fabricated with a high through-plane thermal conductivity of 23.3 W/mK. A high thermal conductivity can be achieved with a significantly low filler level (13.

Diameter control of single-walled carbon nanotube forests from 1.3-3.0 nm by arc plasma deposition.

We present a method to both precisely and continuously control the average diameter of single-walled carbon nanotubes in a forest ranging from 1.3 to 3.0 nm with ~1 Å resolution.

Influence of lengths of millimeter-scale single-walled carbon nanotube on electrical and mechanical properties of buckypaper.

The electrical conductivity and mechanical strength of carbon nanotube (CNT) buckypaper comprised of millimeter-scale long single-walled CNT (SWCNT) was markedly improved by the use of longer SWCNTs. A series of buckypapers, fabricated from SWCNT forests of varying heights (350, 700, 1,500 μm), showed that both the electrical conductivity (19 to 45 S/cm) and tensile strength (27 to 52 MPa) doubled. These improvements were due to improved transfer of electron and load through a reduced number of junctions for longer SWCNTs.

The infinite possible growth ambients that support single-wall carbon nanotube forest growth.

We report the virtually infinite possible carbon feedstocks which support the highly efficient growth of single-wall carbon nanotubes (SWCNTs) using on the water-assisted chemical vapor deposition method. Our results demonstrate that diverse varieties of carbon feedstocks, in the form of hydrocarbons, spanning saturated rings (e.g.

Absence of an ideal single-walled carbon nanotube forest structure for thermal and electrical conductivities.

We report the fundamental dependence of thermal diffusivity and electrical conductance on the diameter and defect level for vertically aligned single-walled carbon nanotube (SWCNT) forests. By synthesizing a series of SWCNT forests with continuous control of the diameter and defect level over a wide range while holding all other structures fixed, we found an inverse and mutually exclusive relationship between the thermal diffusivity and the electrical conductance. This relationship was explained by the differences in the fundamental mechanisms governing each property and the optimum required structures.

One hundred fold increase in current carrying capacity in a carbon nanotube-copper composite.

Increased portability, versatility and ubiquity of electronics devices are a result of their progressive miniaturization, requiring current flow through narrow channels. Present-day devices operate close to the maximum current-carrying-capacity (that is, ampacity) of conductors (such as copper and gold), leading to decreased lifetime and performance, creating demand for new conductors with higher ampacity. Ampacity represents the maximum current-carrying capacity of the object that depends both on the structure and material.
