1.5 µm wavelength high power buried heterojunction (BH) semiconductor lasers having dilute waveguide structure have been fabricated. The optical field is dragged down toward the n side of the device by the dilute waveguide layer, lowering the optical confinement factor of the p doped material and active material, which helps to enlarge the laser output light power.

In this paper, we present a novel, to our knowledge, method for the fabrication of slotted surface gratings for buried heterostructure (BH) lasers. In the device fabrication process, SiO strips needed for InP current blocking layer growth are reused for the formation of slot grating pattern masks. In the following growth of the p-InP cladding layer, because the slot areas are covered by SiO, the InP material is grown selectively in only the areas outside the slot areas, forming slots of the surface gratings in the p-InP layer at the same time as the cladding layer growth.

A single-mode InGaAsP/InP buried heterostructure (BH) laser based on high-order slotted surface gratings has been fabricated. The introduction of surface slotted grating can simplify the fabrication process of single-mode BH lasers notably. The laser shows a good single-mode emission performance, with larger than 30 dB side-mode suppression ratio (SMSR) when the current is between 200 and 400 mA.

The diagnosis of invasive pulmonary aspergillosis (IPA) diseases in non-neutropenic patients remains challenging. It is essential to develop optimal non-invasive or minimally invasive detection methods for the rapid and reliable diagnosis of IPA. Metagenomic next-generation sequencing (mNGS) in bronchoalveolar lavage fluid (BALF) can be a valuable tool for identifying the microorganism.

The repertoire of aberrant signaling underlying the pathogenesis of lung adenocarcinoma remains largely uncharacterized, which precludes an efficient therapy for these patients, especially when distant metastasis occurs. Cyclin-dependent kinase 10 (CDK10) has been reported to modulate the progression of malignant tumors; however, contradictory effects have been found among different types of malignant tumors. In the present study, we found that CDK10 was downregulated in lung adenocarcinoma compared with the paired adjacent normal lung tissue, and lower expression level of CDK10 was associated with more frequent N2 staged lymph node and distant metastasis, higher TNM stage, and shorter overall survival.

Introduction: Conventional etiological detection and pathogenic antibody methods make it challenging to identify the atypical pathogens among the community-acquired pneumonia (CAP). Metagenomic next-generation sequencing (mNGS) could rapidly detect all potentially infectious diseases and identifies novel or potential pathogens.

Methods: Eighteen patients diagnosed with atypical CAP were enrolled in this retrospective study, including nine Chlamydia psittaci pneumonia (C.

Rationale: Epithelioid hemangioendothelioma (EHE) is a rare, low to moderate-grade malignancy, even less in pulmonary endovascular neoplasm. Patients with pulmonary EHE have no optimal treatment, resulting in poor prognoses.

Patient Concerns: We reported a 42-year-old man with multiple mild metabolic uptakes in pulmonary endovascular filling defect with a maximum standardized uptake value of 4.

Background: To reveal the function of protein tyrosine phosphatase-L1 (PTPL1) in lung adenocarcinoma.

Methods: Lung cancer cell lines were transfected with short hairpin RNA against PTPL1 (shPTPL1 group) or negative control (shmock group). Quantitative real-time polymerase chain reaction (qRT-PCR) and western blotting were used to verify the transfection efficacy.

Background: As a member of the Ephrin protein family that elicits short distance cell-cell signaling, EphrinA3 has been shown to promote or inhibit tumorigenesis depending on tumor types, but its roles and the underlying mechanisms in lung adenocarcinoma (LUAD) have not been reported.

Materials And Methods: The TCGA database and Kaplan-Meier Plotter database were used to analyze the differential expression of EphrinA3 between LUAD and para-carcinoma tissues, and its effect on overall survival of LUAD patients. CCK-8 assay, Edu assay, and flow cytometry were used to probe the effect of EphrinA3 on the proliferation of LUAD cells, and transwell assay was employed to examine its effect on migration and invasion.

Hypoxic pulmonary hypertension (HPH) is a challenging lung arterial disorder with remarkably high incidence and mortality, and so far patients have failed to benefit from therapeutics clinically available. Max interacting protein 1-0 (Mxi1-0) is one of the functional isoforms of Mxi1. Although it also binds to Max, Mxi1-0, unlike other Mxi1 isoforms, cannot antagonize the oncoprotein c-Myc because of its unique proline rich domain (PRD).

Objective: The efficacy of rapid on-site evaluation (ROSE) combined with computed tomography-guided transthoracic core needle biopsy (CT-guided TCNB) is rarely investigated. This study aimed to evaluate the diagnostic efficiency and safety of ROSE combined with CT-guided TCNB for suspected lung cancer patients.

Materials And Methods: Clinical data from 285 patients who received CT-guided TCNB for suspected lung cancer in Huashan Hospital from 2015 to 2018 were retrospectively analysed.

Primary pulmonary mucinous adenocarcinoma is an unusual histological type of non-small cell lung cancer and has a rare prevalence at a young age. There is no standard first-line therapy for advanced primary pulmonary mucinous adenocarcinoma in children and young adults-this study reports two rare cases of primary pulmonary mucinous adenocarcinoma with anaplastic lymphoma kinase and epidermal growth factor receptor () genes. One is a 13-year-old boy (, and another is a 27-year-old male ().

Article Synopsis
  • - The study aimed to evaluate how well metagenomic next-generation sequencing (mNGS) can diagnose pulmonary tuberculosis (PTB) in patients who either lack sputum or have negative smear results, using samples from bronchoalveolar lavage fluid (BALF) or lung biopsies.
  • - Out of 107 suspected PTB patients, 46 were confirmed with PTB and mNGS showed a sensitivity of 89.13% and specificity of 98.36%, outperforming conventional tests in sensitivity and matching the T-SPOT.TB assay in combined accuracy.
  • - The research concludes that mNGS could be a more effective method for detecting Mycobacterium tuberculosis in challenging cases where traditional testing methods are

Granulomatosis with polyangiitis (GPA) is a rheumatic auto-immune disease involved in vasculitis. It is rarely reported that anti-neutrophil cytoplasmic antibodies (ANCAs) associated with GPA would cause main tract stenosis. The current report documents a 54-year-old woman, with a history of severe cough, presented with wheezing and shortness of breath.

Pyridoxine 5'-phosphate oxidase (PNPO) is an enzyme that converts pyridoxine 5'-phosphate into pyridoxal 5'-phosphate (PLP), an active form of vitamin B6 implicated in several types of cancer. However, the role of PNPO and its regulatory mechanism in epithelial ovarian cancer (EOC) are unknown. In the present study, PNPO expression in human ovarian tumour tissue and its association with the clinicopathological features of patients with EOC were examined.

Human epithelial ovarian cancer (EOC) is the most lethal gynecological disease. However, the molecular mechanisms by which transforming growth factor-β (TGF-β) regulates ovarian tumor progression markers remain unclear. The present data show cytidine monophosphate kinase (CMPK) as an EOC biomarker and are related to the article entitled "Cytidine monophosphate kinase is inhibited by the TGF-β signalling pathway through the upregulation of miR-130b-3p in human epithelial ovarian cancer" [1].

Cytidine monophosphate kinase (CMPK), a member of the nucleoside monophosphate kinase family, plays an important role in the biosynthesis of nucleoside metabolism, DNA repair and tumour development. In this study, we demonstrated for the first time that CMPK was overexpressed in human ovarian epithelial borderline and malignant tumours using tissue microarray. Knockdown of CMPK significantly inhibited epithelial ovarian cancer (EOC) cell proliferation, migration and invasion.

Article Synopsis
  • The study investigates the role of Beta-2-microglobulin (B2M) in various epithelial-type ovarian tumors to determine its potential involvement in cancer development.
  • It finds that B2M is significantly overexpressed in malignant and borderline ovarian tumors, but its levels do not correlate with clinical factors like age or tumor size.
  • Additionally, the research suggests that B2M could be a promising biomarker and treatment target, with its expression regulated by the TGF-β signaling pathway in ovarian cancer cells.
