Multimodal Imaging of Glioma Progression

WFOM was conducted to collect simultaneous reflectance and GCaMP6f fluorescence signal as previously described in Ma et al. (2016a) (link), using high-speed strobed LED illumination (band-pass filtered to be centered at 490, 530 and 630 nm) time-locked with an sCMOS camera (Andor Zyla) acquiring at 50.25 Hz. Reflectance and fluorescence emission light from the brain was collected with a 500–640 nm bandpass filter to reject illumination wavelengths and focused using an AF Micro-NIKKOR 60 mm lens (Nikon). Webcam monitoring of the mouse was collected throughout imaging with infrared illumination.
Mice were imaged longitudinally throughout the period of tumor development, starting at 4 days post glioma cell injection, with each mouse having at least 8 imaging sessions. Each animal was head-restrained for a maximum of two hours per imaging session. Resting state recordings involved 12 to 18 recordings (180 s duration each) over the course of each imaging session. For whisker barrel stimulation, recordings were 30 s in duration (10 s pre-stimulation, 5 s whisker stimulation, 15 s post-stimulation). Stimulation was achieved using a small bar attached to a computer-controlled stepper motor positioned to brush the whiskers in an up-down motion at 20 Hz during the stimulus period. A total of 30 recordings were performed for each of the right and left whiskers per imaging session.

Mammalian Foot Morphology Diversity

The feet of 260 mammalian specimens were photographed. These represent ~5% of all described mammalian species. Specimens were from the skins collections at Liverpool World Museum and National Museums Scotland and specific specimen numbers (when present) can be found in the Supplementary Material (SupplementaryData.pdf). Types of specimens were selected to be proportional to the distribution of mammalian diversity (i.e., more species were sampled from Primates and Rodentia than Artiodactyla). All work was approved by the ethics committee at Manchester Metropolitan University (No: 10682). The objective was to photograph specimens from a range of different genera to ensure diverse examples, since it was observed that mammals from the same genus tended to have similar foot morphology (i.e., see Figure 1f and g for comparison—Leopard, Panthera pardus and Tiger, Panthera tigris). The best specimens available for each genus were selected for photographing, which were identified as the cleanest and best-preserved examples. A digital camera (D3200 with an AF Micro Nikkor 60 mm lens, Nikon, Tokyo, Japan) was positioned above the specimen on a tripod. Photographs were taken with a ruler in focus at the same level of the feet for callibration. A desk lamp was used for photographs when extra light was required.

Fossil Pinites Collection and Imaging

Check if the same lab product or an alternative is used in the 5 most similar protocols
All specimens used in this study (S1 Table) were borrowed from the Herbarium of the University of Tokyo (TI) and the Fossil collections of the Osaka Museum of Natural History (OSA; for details on these herbaria including contact information, see Index Herbariorum [35 ]). No other specimens were used in this study. Specimens were photographed using a D200 camera (Nikon, Tokyo, Japan) with an AF MICRO NIKKOR 60 mm lens (Nikon) under fluorescent illumination.
The holotype of Pinites fujiii stored in TI consists of a female cone, a replica of the cone, and four microscope slides mounting sectioned parts of the cone. No specimen number is assigned to the holotype, while it is registered as “holotype of Pinites fujiii”. The holotype was collected in Seto-shi, Aichi Pref., Japan (Fig 1), from the Seto Formation, but the exact locality is not available.
Other specimens, including Miki’s [30 ] specimens, are stored in OSA F. These specimens were slightly compressed mummifications collected from the Seto or Tokiguchi Formations (Fig 1).

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.
