The average weight of mature seeds was measured by using an electronic analytical balance (Sartorius, Germany). Seeds were dried under room temperature for 2 weeks. Seed weight was measured on the basis of per plant. The seed embryos were treated as previously described (Meng et al., 2017 (link)). The treated embryos were observed, and its images were captured under Carl Zeiss Microscopy GmbH (Germany). Average cotyledon (cell) area and seed size were measured by using ImageJ software. Seeds, embryos, and cotyledon cells were randomly selected and photographed under the same conditions. Two hundred seeds, cotyledons or cotyledon cells were tested in the experiments.

The brain water content was measured using the wet/dry method (Manaenko et al., 2011 (link)). Briefly, after mice from each group were decapitated under deep anesthesia with 5% isoflurane, the whole brains were immediately removed. Each brain was weighed (wet weight [WW]) on an electronic analytical balance (Sartorius, Gottingen, Germany) and then dried at 100°C for 24 h to determine the dry weight (DW). The brain water content (%) was calculated as ([WW − DW]/WW) × 100%.

Rats were anesthetized with pentobarbital (60 mg/kg) and the brains were dissected quickly. Three samples were obtained from the brain: ipsilateral hemisphere, contralateral hemisphere and cerebellum. The brain samples were immediately weighed on the electronic analytical balance (Sartorius, China) to obtain wet weight. The brain sample was then dried at 100°C for 24 h to obtain dry weight. The calculation formula is as follows: (wet weight-dry weight)/wet weight × 100%.

Body weight changes were assessed in the first 72 hours after modeling. In addition, as previously described (Chen et al., 2020), we used the wet/dry weight method to measure brain water content. After anesthetization with pentobarbital, the brain was quickly removed and divided into the cerebrum and cerebellum. Samples were weighed with an electronic analytical balance (Sartorious, Göttingen, Germany) to determine the wet weight. Dry weight was measured after drying at 160°C for 24 hours. The following formula was used to calculate brain water content (%): (wet weight – dry weight)/wet weight × 100. Brain water content in the IVH group was measured on the third day after IVH induction.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
