Leptin is a pleiotropic hormone produced by white adipose tissue that regulates appetite and many physiologic functions including the immune response to infection. Genetic leptin deficiency in humans and mice impairs host defenses against respiratory tract infections. Since leptin deficiency is associated with obesity and other metabolic abnormalities, we generated mice that lack the leptin receptor (LepRb) in cells of the myeloid linage (LysM-LepRb-KO) to evaluate its impact in lean metabolically normal mice in a murine model of pneumococcal pneumonia...

Afatinib exhibits therapeutic efficacy for lung adenocarcinoma patients harboring HER2 exon 20 insertions. HER2 S310Y single site substitution was discovered in recent years and afatinib efficacy for adenocarcinoma patients harboring S310Y mutation has not been reported. We presented a case of a 41-year-old male patient with lung adenocarcinoma harboring the HER2 S310Y mutation obtained clinical response to the treatment of afatinib, an oral HER family blocker. After the treatment of afatinib, the patient achieved partial response (PR) in chest lesions and almost complete response (CR) in intracranial lesions...

A polyimide microfluidic chip with a microhole emitter (Ø 10-12 μm) created on top of a microchannel by scanning laser ablation has been designed for nanoelectrospray ionization (spyhole-nanoESI) to couple microfluidics with mass spectrometry. The spyhole-nanoESI showed higher sensitivity compared to standard ESI and microESI from the end of the microchannel. The limits of detection (LOD) for peptide with the spyhole-nanoESI MS reached 50 pM, which was 600 times lower than that with standard ESI. The present microchip emitter allows the analysis of small volumes of samples...

Background: Intercostal neuralgia is a complex and difficult-to-treat condition. We present 2 cases that demonstrate the safe and effective use of thermal radiofrequency ablation (RFA) to achieve significant pain relief. Case Reports: Our first patient was a 62-year-old female who developed chronic chest pain following lumpectomy for breast cancer and failed conservative management. Two intercostal diagnostic nerve blocks were performed with good results. One block provided pain relief for 3 weeks, and the other provided pain relief for 5 weeks...

Recent studies indicated that insufficient radiofrequency ablation (RFA) could endow hepatocellular carcinoma (HCC) with higher aggressive potential. Stress-induced phosphoprotein 1 (STIP1), which was found highly expressed in HCC, is a chaperone molecule mediating cell homeostasis under thermal stress. We aimed to explore the role of STIP1 on the metastasis of residual HCC after RFA. Mice model with orthotopic HCC implants or caudal vein injection were employed to assess potential of lung metastasis and/or intrahepatic metastasis (IHM) of HCC cells...

One of the major complications of radiofrequency catheter ablation (RFCA) for atrial fibrillation (AF) is pulmonary vein stenosis (PVS). The natural history of PVS, especially when it involves more than one vein, leads to severe and irreversible pulmonary hypertension with end-stage right heart failure that can require, in extreme cases, even heart-lung transplantation. We report the case of a young patient who underwent RFCA for a single lasting episode of AF and developed PVS years later. He was treated with ballon venoplasty followed by stent implantation in left pulmonary vein because of PVS relief...

Tumor combination therapy using nano formulations with multimodal synergistic therapeutic effects shows great potential for complete ablation of tumors. However, targeting tumor metastases with nano structures is a major obstacle for therapy. Therefore, developing a combination therapy system able to target both primary tumors and their metastases at distant sites with synergistic therapy is desirable for the complete eradication of tumors. To this end, a dual chemodrug-loaded theranostic system based on single walled carbon nanohorns (SWNHs) is developed for targeting both primary breast tumors and their lung metastases...

Ablation treatments are the minimally invasive surgical procedures that are used to treat early stage cancers. High intensity ultrasonic treatments that are used to treat solid cancers are not much successful in differentiating between healthy and cancerous cells. In this study, a method of combining ultrasound treatment with Garcinia mangostana bark extract mediated silver nanoparticles (AgNPs) was extended by making use of human lung epithelial cells, that could preferentially destruct the cancerous cells...

The emergence of microRNA as regulators of organogenesis and tissue differentiation has stimulated interest in the ablation of microRNA expression and function during discrete periods of development. To this end, inducible, conditional modulation of microRNA expression with doxycycline-based tetracycline-controlled transactivator and tamoxifen-based estrogen receptor systems has found widespread use. However, the induction agents and components of genome recombination systems negatively impact pregnancy, parturition, and post natal development; thereby limiting the use of these technologies between late gestation and the early post-natal period...

Alveolar macrophages (AMs) are pivotal for maintaining the lung homeostasis, but how the development and function of AMs regulated remains largely unknown. In the present study, we demonstrated that the number of AMs was controlled by the Tsc1 protein. Cd11c-specific deletion of Tsc1 caused inefficient transition from pre-AMs to AMs in lung, which led to a great reduction of AM population. Ablation of Tsc1 downregulated the expression of surface marker CD64 and SiglecF on AMs. We further showed that conditional knockout of Tsc1 led to enhanced proliferation and increased reactive oxygen species (ROS) production and phagocytosis in AMs...

BACKGROUND: An elevated thyroid stimulating hormone (TSH) level is essential for the uptake of radioiodine into thyroid remnants and residual thyroid cancer in patients undergoing high-dose radioiodine therapy (HD-RIT). Recently, the use of recombinant human thyroid stimulating hormone (rh- TSH) has increased in preference over the conventional method of thyroid hormone withdrawal (THW). However, the clinical influences of the two methods, aside from the therapeutic effects, have not been widely evaluated...

Iron Pill Aspiration (IPA) is a challenging medical condition that requires prompt management to prevent detrimental outcomes. One of the most serious complications of IPA is airway inflammation which commonly leads to severe obstruction. Airway complications may require surgical intervention including the resection of the affected lung. Prompt recognition and management of IPA can reduce the risk of airway complications and may prevent the need of a surgical intervention. Bronchoscopic management entails the use of flexible and rigid bronchoscopes along with balloon bronchoplasty, ablation of the inflammatory tissue causing obstruction and airway stenting...

PURPOSE: Stereotactic ablative body radiotherapy (SABR) represents an exciting, tolerable, and highly effective form of radiotherapy. Ongoing investigations into the interactions between radiotherapy and the immune system have uncovered new mechanisms that can be exploited to improve efficacy. We determined whether baseline or posttreatment immune parameters could predict disease control and toxicity in stage I non-small-cell lung cancer (NSCLC) patients treated with SABR. PATIENTS AND METHODS: Peripheral blood samples were collected from 62 patients 24 hours before treatment and within 4 weeks after treatment for lymphocyte subset count analysis...

Distinctive patterns of early and late benign fibrosis are commonly observed after stereotactic ablative radiotherapy (SABR) for lung malignancies. These changes on computed tomographic scans need to be distinguished from so-called 'high-risk' radiological features, which can be associated with a higher risk for tumor recurrence. This pictorial report illustrates the different radiological changes seen following SABR delivered using the volumetric modulated radiotherapy, a technique which is increasingly used in clinical care...
