Article Synopsis
- Lighting plays a significant role in poultry production, and this study assessed how LED lighting (green vs. white) impacts broiler breeders' performance and bone characteristics, including mineralization and gene expression.
- 800 one-day-old female Ross 308 broilers were divided into groups under different lighting conditions (green, white, and a control with incandescent light) for two photoperiods (8 or 12 hours) to analyze weight gain, feed intake, and bone metrics.
- Results indicated higher feed intake under white light, with varying effects on tibial calcium levels and bone characteristics depending on light color and duration, suggesting that LED lighting can positively influence bone traits in broiler breeders.
Article Synopsis
- The study aims to explore the connection between digestive diseases and COVID-19, focusing on patients with and without gastrointestinal symptoms.
- It involved a case-control design with 190 COVID-19 patients divided into two groups: one with gastrointestinal symptoms and one without, using noninvasive diagnostic methods to identify infections.
- Results showed a significant prevalence of infection in patients with gastrointestinal symptoms, suggesting that this should be considered when treating COVID-19 infected individuals.
Background: Suppression of the body's immune system can cause high blood pressure. Also, many people with COVID-19 have underlying diseases, including high blood pressure.
Aim: This study was conducted to investigate the effect of COVID-19 infection on blood pressure caused by pregnancy in women referred to Kashani Hospital in Jiroft City.
Introduction: Quantification of dynamic contrast-enhanced (DCE)-MRI has the potential to provide valuable clinical information, but robust pharmacokinetic modeling remains a challenge for clinical adoption.
Methods: A 7-layer neural network called DCE-Qnet was trained on simulated DCE-MRI signals derived from the Extended Tofts model with the Parker arterial input function. Network training incorporated B inhomogeneities to estimate perfusion (K, v, v), tissue T relaxation, proton density and bolus arrival time (BAT).
A novel palladium-loaded yolk-shell structured nanomaterial with magnetite core and phenylene-based periodic mesoporous organosilica (PMO) shell (FeO@YS-Ph-PMO/Pd) nanocatalyst was synthesized for the reduction of nitrobenzenes. The FeO@YS-Ph-PMO/Pd was prepared through cetyltrimethylammonium bromide (CTAB) directed condensation of 1,4-bis(triethoxysilyl)benzene (BTEB) around FeO@silica nanoparticles followed by treatment with palladium acetate. This nanocatalyst was characterized by using Fourier transform infrared (FT-IR) spectroscopy, thermal gravimetric analysis (TGA), low-angle and wide-angle powder X-ray diffraction (PXRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and vibrating sample magnetometer (VSM) analyses.
