Back to Basaloid: Revisiting the Diagnostic Dilemma of Basaloid Squamous Carcinoma Versus Small Cell Carcinoma on Lung Fine Needle Aspiration Biopsy Cytology

Diagnostic Cytopathology, EarlyView.
ABSTRACT Background Basaloid Squamous cell carcinoma (BSCC) is a rare subtype of squamous cell carcinoma whose cytomorphologic features on lung fine needle aspiration (FNAB) can mimic small cell lung carcinoma (SCLC), creating a diagnostic dilemma. As the distinction is critical for patient management and prognosis, this study aimed to determine if ...

Mechanism and disaster control new technology of strong ground pressure manifestation in ultra‐large mining face

Deep Underground Science and Engineering, EarlyView.
In response to the problem of strong mining pressure manifestation along the goaf roadway in a thick coal seam mining area, this study uses a new type of combined blasting roof cutting technology to effectively control the manifestation and deformation of mining pressure along the goaf roadway.

Mechanism of “seesaw‐type” rock burst in coal seam mining beneath mountainous areas

Deep Underground Science and Engineering, EarlyView.
This study reveals the mechanism of “seesaw‐type” rock bursts during coal mining beneath mountainous areas. The advancing working face induces nonuniform fracturing of the overburden. The detached mountain mass then undergoes a seesaw‐type rotational movement around a shifting pivot, driving the primary fracture through a characteristic “open‐close ...

A single base‐pair variation in a limb‐specific Lhx9 cis‐regulatory region modulates HAND2‐associated posterior repression

Developmental Dynamics, EarlyView.
Abstract LIM Homeobox 9 (Lhx9) is a transcription factor involved in vertebrate limb development. Despite conserved anterior expression, its distal expression is species‐specific. In chickens, distal expression is restricted to the anterior mesoderm; in mice, it extends into posterior mesoderm.

Modelling granular soil to predict pressures on integral bridge abutments

Presented here is a granular soil model created to investigate the soil pressureswhich develop behind integral bridge abutments. The problem is introduced along with a briefsummary of the fundamental behaviour, the model produced, and the initial ...
