BM-BronchoLC - A rich bronchoscopy dataset for anatomical landmarks and lung cancer lesion recognition.

Flexible bronchoscopy has revolutionized respiratory disease diagnosis. It offers direct visualization and detection of airway abnormalities, including lung cancer lesions. Accurate identification of airway lesions during flexible bronchoscopy plays an important role in the lung cancer diagnosis.

A novel GPI-anchored dominant-negative TGF-β receptor II renders T cells unresponsive to TGF-β signaling.

Transforming growth factor β (TGF-β) is a pleiotropic cytokine expressed by a wide range of cell types and is known for hampering the effectiveness of cancer immune cell therapeutic approaches. We have designed a novel construct containing the extracellular domain of the TGF-β receptor II linked to a glycosylphosphatidylinositol (GPI) anchor (GPI-ecto-TβRII) lacking the transmembrane and cytoplasmic signaling domain of TGF-β receptor II (TβRII). T cells transduced with lentivirus expressing the GPI-ecto-TβRII construct show 5 to 15 times higher membrane expression compared with a previously established dominant-negative receptor carrying a truncated signaling domain.

Structure, anticoagulant and cytotoxic activity of a sulfated polysaccharide from green seaweed .

In this article, chemical structure and conformation in an aqueous solution of a new sulfated polysaccharide, P, extracted from green seaweed were elucidated by SEC-MALL, IR, NMR and SAXS. The results indicated that the obtained polysaccharide is a sulfated arabinogalactan with a molecular weight of 223 kDa, and is mainly composed of →3,6)-α-D-Gal4S→ and →2)-α-L-Ara→ connecting together through 1→3 glycoside linkages. It has a broken rod-like conformation in solution with estimated as 0.

Predictive Factors for Clinical Outcome After Direct Mechanical Thrombectomy for Anterior Circulation Large Vessel Occlusion Within 4.5 h.

Background: Recent trials including DIRECT-MT, DEVT, and SKIP have found that direct mechanical thrombectomy (MT) is equally effective as the combination of MT and intravenous thrombolysis. However, the results of the other trials, namely MR-CLEAN NO-IV and the SWIFT-DIRECT trial have failed to confirm the non-inferiority of direct MT vs. the combination therapy.

Automatic scan range for dose-reduced multiphase CT imaging of the liver utilizing CNNs and Gaussian models.

Multiphase CT scanning of the liver is performed for several clinical applications; however, radiation exposure from CT scanning poses a nontrivial cancer risk to the patients. The radiation dose may be reduced by determining the scan range of the subsequent scans by the location of the target of interest in the first scan phase. The purpose of this study is to present and assess an automatic method for determining the scan range for multiphase CT scans.

Efficacy and Safety of Radiofrequency Ablation for the Treatment of Autonomously Functioning Thyroid Nodules: A Long-Term Prospective Study.

Objective: This study aims to evaluate the efficacy and safety of RFA in the AFTN treatment after 2 years of follow-up and to find the factors related to treatment responses through TSH level and VRR.

Materials And Methods: This long-term prospective study was conducted from September 2017 to April 2021 on 17 AFTNs treated with RFA. Clinical evaluations, thyroid function tests, thyroid scintigraphy, and ultrasonography examinations were performed at 1 month, 3 months, 6 months, and 24 months after ablation.

Simultaneous mechanical thrombectomy for bilateral acute internal carotid artery occlusion.

Acute bilateral internal carotid occlusion was a very rare disease with a very poor prognosis. Clinical case reports according to the literature showed that mechanical thrombectomy was the most optimal treatment. We reported a clinical case of successful treatment with simultaneous thrombectomy in both occluded carotid arteries.

A case report of Mikulicz's disease.

Mikulicz's disease is a unique condition involving the enlargement of the lacrimal and salivary glands, similar to that observed in Sjogren's syndrome; however, Mikulicz's disease is clinically characterized by infrequent autoimmune reactions and responsiveness to glucocorticoid treatment. The ultrasound features of the lacrimal and salivary glands in patients with IgG4-Mikulicz's disease were characterized by multiple hypoechoic areas of varying sizes within the enlarged glands. IgG4 serum level was also elevated, in contrast to the detection of normal levels in Sjogren's syndrome.

Intrahepatic lymphatic channel sclerotic embolization for treatment of postoperative lymphatic ascites: a report of 3 cases.

Postoperative hepatic lymphorrhea is extremely rare and there is no standard treatment for this condition. We report the cases of 3 men, 32-, 56-, and 37-year-old, with postoperative hepatic lymphorrhea, which was refractory to conservative treatment. Transhepatic lymphangiography allowed locating the lymphatic leak and treating it with hepatic lymphatic vessels injection of foam sclerotic agent.

Basilar artery thrombectomy: assessment of outcome and identification of prognostic factors.

Mechanical thrombectomy (MT) has been demonstrated as an effective treatment for acute ischemic stroke (AIS), thanks to large vessel occlusion (LVO), especially in case of anterior cerebral artery with many randomized clinical trials (RCTs) every year. On the other hand, there is a limited number of basilar artery occlusion (BAO)-related studies which have been conducted. The fact prompts our range of case studies, which furnish BAO understanding with our experience, results and some prognosis factors of MT.

Yersinia pestis Orientalis in remains of ancient plague patients.

Yersinia pestis DNA was recently detected in human remains from 2 ancient plague pandemics in France and Germany. We have now sequenced Y pestis glpD gene in such remains, showing a 93-bp deletion specific for biotype Orientalis. These data show that only Orientalis type caused the 3 plague pandemics.

Molecular detection of Bartonella spp. in the dental pulp of stray cats buried for a year.

Bartonella henselae causes chronic bacteremia in cats. To test if B. henselae DNA can be recovered from the dental pulp of cats buried a year previously, we used PCR with primers for a sequence of the conserved groEL to test 104 teeth from 11 cats.

Genotyping, Orientalis-like Yersinia pestis, and plague pandemics.

Three pandemics have been attributed to plague in the last 1,500 years. Yersinia pestis caused the third, and its DNA was found in human remains from the second. The Antiqua biovar of Y.
