Aquaculture, particularly shrimp farming, is crucial for global food security. However, the increasing presence of microplastics (MPs) in marine environments, shrimp feeds, and atmospheric particles has made MP contamination in shrimp tissues inevitable. This study systematically investigates the abundance, characteristics, and temporal trends (from 15th to the 120th day of culture) of MPs contamination in Litopenaeus vannamei, along with associated feed, water, and sediment across 12 shrimp ponds of two major shrimp-producing regions of India.

Shortwave infrared (SWIR)-emitting materials have emerged as superior light sources with increasing demand for potential applications in noninvasive analysis, night vision illumination, and medical diagnosis. For developing next-generation SWIR phosphor-converted light-emitting diodes (pc-LEDs), the scarcity of intense blue-light-pumped broadband SWIR luminescent materials and poor thermal stability of current Ni-activated phosphors are the ongoing challenges. Here, a blue-light-excitable (440 nm) YAlGaO:Cr,Ni phosphor with ultrawide SWIR emission centered at ∼1430 nm (FWHM ∼264 nm) is reported.

Background: Benign airway stenoses are complex disorders that present with progressive dyspnoea, stridor, and significant respiratory distress. These conditions have a high recurrence rate and despite the plethora of endoscopic and open techniques available for treatment, the outcomes are variable. Our primary was to determine the pre-operative factors associated with an increased hazard of cricotracheal resection (CTR)/tracheal resection (TR) and reconstruction in cases of benign subglottic and tracheal strictures.

Article Synopsis
  • Pectus defects, which occur in about 1 in 250 people, include conditions where the sternum either sinks in (excavatum) or protrudes out (carinatum), impacting some individuals psychologically and physiologically.
  • Most cases are mild and don't hinder daily activities, but some patients experience lower self-esteem and depression, avoiding social situations due to physical appearance issues.
  • Treatment options vary from supportive care and psychological support to non-surgical methods like bracing, as well as surgical options like the Nuss and Ravitch procedures for severe cases, with many patients only needing supportive care.

Introduction: B cells, which have long been thought to be minor players in the development of anti-tumor responses, have been implicated as key players in lung cancer pathogenesis and response to checkpoint blockade in patients with lung cancer. Enrichment of late-stage plasma and memory cells in the tumor microenvironment has been shown in lung cancer, with the plasma cell repertoire existing on a functional spectrum with suppressive phenotypes correlating with outcome. B cell dynamics may be influenced by the inflammatory microenvironment observed in smokers and between LUAD and LUSC.

Metastatic disease is responsible for the majority of cancer-related deaths. We report the longitudinal evolutionary analysis of 126 non-small cell lung cancer (NSCLC) tumours from 421 prospectively recruited patients in TRACERx who developed metastatic disease, compared with a control cohort of 144 non-metastatic tumours. In 25% of cases, metastases diverged early, before the last clonal sweep in the primary tumour, and early divergence was enriched for patients who were smokers at the time of initial diagnosis.
