Horseshoe lung is a rare congenital pulmonary anomaly of childhood that can be accompanied with other anomalies. The diagnosis has historically been accomplished with invasive catheter angiography and bronchography rather than CT. Two infants with horseshoe lung were recently diagnosed with CT. We report the imaging findings in these two patients with emphasis on angiographic and bronchographic demonstration of key abnormalities of horseshoe lung using multidetector-row spiral CT.

Potential role of the antimicrobial peptide Tachyplesin III in regulating nontypeable Haemophilus influenzae-induced inflammation in airway epithelial cells.

Article Synopsis
- Nontypeable Haemophilus influenzae (NTHi) is a major contributor to inflammation in chronic obstructive pulmonary disease (COPD), necessitating new treatments due to limitations of current drugs.
- A study investigated Tachyplesin III, an antimicrobial peptide from horseshoe crabs, and found it significantly reduced key inflammatory markers (like IL-1β and TNF-α) in human lung cells exposed to NTHi without being toxic.
- The research also showed that Tachyplesin III inhibits the NF-κB/NLRP3 signaling pathway, suggesting it could be a valuable new option for addressing NTHi-related airway inflammation in COPD patients.
ACE2-independent sarbecovirus cell entry can be supported by TMPRSS2-related enzymes and can reduce sensitivity to antibody-mediated neutralization.

The COVID-19 pandemic, caused by SARS-CoV-2, demonstrated that zoonotic transmission of animal sarbecoviruses threatens human health but the determinants of transmission are incompletely understood. Here, we show that most spike (S) proteins of horseshoe bat and Malayan pangolin sarbecoviruses employ ACE2 for entry, with human and raccoon dog ACE2 exhibiting broad receptor activity. The insertion of a multibasic cleavage site into the S proteins increased entry into human lung cells driven by most S proteins tested, suggesting that acquisition of a multibasic cleavage site might increase infectivity of diverse animal sarbecoviruses for the human respiratory tract.

In addition to considering the main effects, understanding gene-environment (G × E) interactions is imperative for determining the etiology of diseases and the factors that affect their prognosis. In the existing statistical framework for censored survival outcomes, there are several challenges in detecting G × E interactions, such as handling high-dimensional omics data, diverse environmental factors, and algorithmic complications in survival analysis. The effect heredity principle has widely been used in studies involving interaction identification because it incorporates the dependence of the main and interaction effects.

Article Synopsis
- Researchers isolated a coronavirus called BANAL-20-236 (B236) from Malayan horseshoe bats and found it lacks a key site in its spike protein that is present in SARS-CoV-2.
- * They compared B236's characteristics using human-derived cells and hamster infection experiments, discovering it's less pathogenic and grows slower in respiratory cells compared to SARS-CoV-2, but grows better in intestinal cells.
- * The study suggests that SC2r-CoVs like B236 may primarily replicate in the intestines rather than the respiratory system, supporting prior findings about its behavior in other models.
