Many teachers substitute dissections with virtual labs or paper versions of dissections where students label, color, or cut out parts. This worksheet shows a simplified diagram of a human and a rabbit digestive system where students label the main structures using a word bank. Discussion questions...
Adult human fibroblasts (#PCS-201-012, ATCC) were used as a control for the fibrosarcoma, MSC for the Ewing sarcoma and primary human skeletal muscle cells (SKMC, #PCS-950-010, ATCC) for the rhabdomyosarcoma. Chondrocytes, fibroblasts, skeletal muscle cells were cultured in RPMI 1640 with L...
Passive microfluidic separation devices can also be classified into two types: labeled and label-free. Labeled devices contain functional molecules attached to a substrate or on the particles themselves. When particles in a fluid sample stream pass the substrate, they will be attached to the function...
MicroRNAs (miRNAs) bind to the 3ʹ-untranslated region of target mRNAs in a sequence-specific manner and subsequently repress gene translation. Human miR-26a has been studied extensively, but the target transcripts are far from complete. We first emplo
Meat is a major source of minerals in human nutrition, particularly of trace minerals and heme-iron, which consist primarily of myoglobin and hemoglobin (Benito & Miller, 1998; Cabrera, Ramos, Saadoun, & Brito, 2010; Santaella, Martínez, Ros, & Periago, 1997). The trace mineral content of...
During the last 20 years, a multitude of anti-aging practices have appeared worldwide, aiming at retarding or even stopping and reversing the effects of aging on the human body. One of the cornerstones of anti-aging is hormone replacement. At present, women live one ...
During the last 20 years, a multitude of anti-aging practices have appeared worldwide, aiming at retarding or even stopping and reversing the effects of aging on the human body. One of the cornerstones of anti-aging is hormone replacement. At present, women live one third of their lives in...
Skeletal muscle has a great economic value accounting for up to 50% of the total body weight of an animal and is in the order of 25% of basal metabolic expenditure19,20. This tissue also plays a major role in energy homeostasis. Therefore skeletal muscle (M.longissimus dorsi) was selected...
From 3 µg to 5 µg of unfractionated tryptic digests that are obtained from proteomics-typical amounts of starting material, microLC-SWATH-MS quantifies up to 4000 human or 1750 yeast proteins in an hour or less. In the acquisition of 750 yeast proteomes, retention times varied ...
The toxicity of mercury is in the first place among the toxic heavy metals, and it is easy to accumulate in human body and animals even very low concentration through the food chain1–2. Inorganic mercury can bind with pro- tein, and inhibit the enzyme's activity to retard cell metabolism...
