Meta-analysis and systematic review of mediastinal cryobiopsy versus endobronchial ultrasound-transbronchial needle aspiration (EBUS-TBNA) in the diagnosis of intrathoracic adenopathy.

Background: Endobronchial ultrasound (EBUS)-guided mediastinal/hilar cryobiopsy (MedCryoBx) is a relatively new modality, being combined with EBUS-transbronchial needle aspiration (TBNA) to improve yield in the diagnosis of intrathoracic adenopathy. This meta-analysis aims to investigate the diagnostic yield of MedCryoBx versus EBUS-TBNA for intrathoracic adenopathy.

Methods: We conducted a systematic search using Google Scholar, Embase, and PubMed/MEDLINE for studies about a diagnosis of intrathoracic adenopathy using MedCryoBx and EBUS-TBNA.

[Transbronchial cryobiopsy for mediastinal lesions: a pilot study].

Objective: To describe a novel transbronchial cryobiopsy technique for mediastinal lesions after initial ultrasound assessment and EBUS-TBNA.

Material And Methods: Transbronchial cryobiopsy (TBCB) was performed in 35 patients with suspicious mediastinal lesions between November 2020 and September 2022. Age of patients ranged from 22 to 75 years (median 50 [39; 62]).

Diffuse Lung Disease in Convalescents of COVID-19.

The most common causes of diffuse interstitial lung damage following COVID-19, often either imitate it but have a different nature or remain due to prolonged persistence of SARS-CoV-2 in the lower respiratory tract. A diagnostic algorithm is proposed to make mostly a correct diagnosis, the key element of which is study of the bronchoalveolar lavage fluid.

Overexpression of increases maize grain yield in the field.

Increasing maize grain yield has been a major focus of both plant breeding and genetic engineering to meet the global demand for food, feed, and industrial uses. We report that increasing and extending expression of a maize MADS-box transcription factor gene, , under the control of a moderate-constitutive maize promoter, results in maize plants with increased plant growth, photosynthesis capacity, and nitrogen utilization. Molecular and biochemical characterization of transgenic plants demonstrated that their enhanced agronomic traits are associated with elevated plant carbon assimilation, nitrogen utilization, and plant growth.
