What Causes Microcephaly?

Patient Presentation A 5-month-old male came to clinic for his health supervision visit and followup from his neonatal intensive care stay. He was born prematurely at 28 weeks gestation and his stay was complicated by a right sided Grade III intraventricular hemorrhage, a left-sided Grade IV intraventricular hemorrhage, neonatal seizures, respiratory distress and bronchopulmonary dysplasia, retinopathy of prematurity, acute kidney injury that had resolved, possible necrotizing enterocolitis incidents x 2, and herpes simplex encephalitis. He was on home oxygen, a nasogastric feeding tube because of aspiration risk and multiple medications. He was taken care of by his mother, maternal grandmother and home nursing. He was to start home physical therapy, and had multiple followup appointments for specialty care already arranged. The pertinent physical exam showed a small infant with a nasal canula and feeding tube in place. Weight (= 4.116 kg) and height (=54 cm) were at the 3th percentile and tracking. Head circumference was

It is a growing trend to develop an eco-friendly and nuisanceless OSDA for zeolite synthesis. Herein, choline is employed as a non-toxic and green OSDA to synthesize high silica Y zeolite with SiO2/Al2O3 ratios of 6.5–6.8. The prepared Y zeolite samples exhibited o...

DalmacijaAbstractPolycyclic aromatic hydrocarbons (PAHs) are amongst the most abundant contaminants found in the aquatic environment. Due to their toxicity and carcinogenicity, their sources, fate, behaviour, and cleanup techniques have been widely investigated in the last several decades. When entering the sediment-water system, PAH fate is determined by particular PAH and sediment physico-chemical properties. Most of the PAHs will be associated ...

Two-dimensional correlation spectroscopy (2D-COS) analysis on Fourier-transform infrared (FTIR), ultraviolet visible (UV–vis), and synchronous fluorescence spectra (SFS) were used to investigate the metal binding properties of compost-derived DOM. Synchronous and asynchronous maps of 2D-FTIR-COS of DO...
