Blue light cystoscopy- as an improvised diagnostic modality for bladder tumours.
J Pak Med Assoc
January 2025
Department of Physiology, Karachi University, Karachi, Pakistan.
Bladder cancer remains a significant global health concern, being the 10th most common malignancy worldwide and the 6th most common neoplasia in males, with alarming annual incidence and mortality rates. The current narrative review was planned to delve into the multifaceted landscape of bladder cancer, exploring its epidemiology, risk factors and diagnostic modalities. While white light cystoscopy has long been considered the gold standard for bladder cancer diagnosis and surveillance, the emergence of blue light cystoscopy has ushered in a new era of early detection.

Department of Gynecology, Maternal and Child Health Hospital of Hubei Province, Tongji Medical College, Huazhong University of Science and Technology, Wuhan, 430070, China.
Purpose: The application of narrow-band imaging for missed early miscarriage treatment remains unclear. This study determined the application advantages of NBI combined with hysteroscopic 7Fr cold knife embryo removal for treating missed early miscarriage.
Methods: A retrospective selection of 208 patients who were hospitalized for missed early miscarriage at Hubei Provincial Maternal and Child Health Hospital from January 2023 to June 2023 were included.
Quantum magnetometry of transient signals with a time resolution of 1.1 nanoseconds.

Department of Physics, ETH Zürich, Otto-Stern-Weg 1, 8093, Zürich, Switzerland.
Quantum magnetometers based on spin defects in solids enable sensitive imaging of various magnetic phenomena, such as ferro- and antiferromagnetism, superconductivity, and current-induced fields. Existing protocols primarily focus on static fields or narrow-band dynamical signals, and are optimized for high sensitivity rather than fast time resolution. Here, we report detection of fast signal transients, providing a perspective for investigating the rich dynamics of magnetic systems.

J Bronchology Interv Pulmonol
April 2025
Department of Medicine, Division of Respirology, University of Calgary, Calgary, AB.
Background: Diagnosis of sarcoidosis often involves endobronchial biopsy (EBB), but studies have shown varying yields for EBB in suspected sarcoidosis, partly due to differences in identifying abnormal mucosa under white light (WL). Narrow band imaging (NBI) may assist in the visualization of abnormal mucosa, but its role in sarcoidosis remains to be characterized.
Methods: Individuals referred for suspected sarcoidosis were considered for enrollment.
Band Tailoring Enabled Perovskite Devices for X-Ray to Near-Infrared Photodetection.
Adv Sci (Weinh)
January 2025
School of Integrated Circuits and Beijing National Research Center for Information Science and Technology (BNRist), Tsinghua University, Beijing, 100084, China.
Perovskite semiconductors have shown significant promise for photodetection due to their low effective carrier masses and long carrier lifetimes. However, achieving balanced detection across a broad spectrum-from X-rays to infrared-within a single perovskite photodetector presents challenges. These challenges stem from conflicting requirements for different wavelength ranges, such as the narrow bandgap needed for infrared detection and the low dark current necessary for X-ray sensitivity.
