In the world's oceans, even relatively low oxygen levels inhibit anaerobic nitrogen cycling by free-living microbes. Sinking organic aggregates, however, might provide oxygen-depleted microbial hotspots in otherwise oxygenated surface waters. Here, we show that sinking diatom aggregates can host anaerobic nitrogen cycling at ambient oxygen levels well above the hypoxic threshold. Aggregates wer...
Bone resorption is a known complication of cranioplasty after decompressive craniectomy (DC). A peculiar group of insidious, progressive, invalidating neurological symptoms was observed in patients presenting with incomplete resorption and abnormal mobility of the re-implanted bone. Such symptoms were similar, but with time more severe, to those encountered in the sinking flap syndrome. Are we ...
میزان مرگ و میر آسم طی دهه گذشته بطور چشمگیری تغییر کرده است. با مبتلا کردن ۱۵ میلیون آمریکایی میزان مرگ و میر در سال ۱۹۷۸، به رقم ۱۸۷۲ نفر و ۹ سال بعد، به بیش از ۴۰۰۰ نفر رسید. علت چنین افزایش چشمگیری روشن نیست. علل احتمالی عبارتند از کاهش ظرفیت تنفس، استفاده بیش از حد از داروهای استثنائی و استنباط غلط بیماران و نیز مراکز درمانی نسبت به شدت بیماری است. بررسی دقیق، معالجات مناسب و آموزش به ب...
