Objectives: To produce standards of references for quality control and assess the reproducibility of fetal ultrasound Doppler measurements commonly used for blood flow assessment in fetal growth.

Methods: Women with singleton normal pregnancies were prospectively recruited at University College London Hospital, UK, between 24 and 41 weeks. Umbilical artery (UA), middle cerebral artery (MCA), and their pulsatility indices (PI), resistance indices (RI) and ratios such as cerebro-placental (CPR) and umbilical cerebral ratio (UCR) were obtained twice by two sonographers in training or after completion of training, blind to each other's measurements.

Objective: To describe postnatal outcome following the prenatal diagnosis of an abnormal fetal gallbladder.

Methods: We conducted a systematic review of studies from January 1980 to January 2023 that described FGB abnormalities, which included agenesis or non-visualisation, abnormal content presence of sludge, abnormal shape or size and abnormal position, and postnatal outcome to determine the association with pathology.

Results: In 51 studies, 842 fetuses had abnormal FGB.

Article Synopsis
  • - The study investigates the impact of heavy metals and microplastics on marine life by analyzing water and tissue samples from macroalgae, prawns, and crabs along the Gujarat coast.
  • - High levels of chromium, nickel, and copper were found in specific locations and organisms, with mercury and nickel showing significant accumulation patterns.
  • - There was a notable presence of various microplastic types (like threads and fragments) in the samples, indicating pollution levels surpassing safe limits across different marine food chains, necessitating urgent environmental policy changes.

Quantum dots (QDs), also known as nanoparticle-based fluorescent probes, are luminescent semiconductor particles with a size range of 2-20 nm. The unique optical and electronic capabilities of QDs have led to expanded applications in several fields such as optoelectronics, transistors, sensors, photodetection, catalysis, and medicine. The distinct quantum effects of nanocrystals can be controlled by changing their sizes and shapes using a variety of top-down and bottom-up tactics.

Aminocarb (AMC), a carbamate pesticide, due to its prevalent usage exhibits increased accumulation in the environment affecting both insects and humans. It enters the human body via food grains and be transported through bloodstream. AMC's chemical structure, containing specific molecular frameworks and functional groups, enables it to bind with proteins like albumin and hemoglobin.
