Phocidae

Phocidae, also known as earless seals or true seals, are a family of semiaquatic marine mammals that belong to the order Pinnipedia.
These seals are characterized by their lack of external ears, their streamlined bodies, and their ability to propel themselves through the water using their hind flippers.
Phocidae are found in cold and temperate regions around the world, including the Arctic and Antarctic Oceans, as well as in coastal areas of North America, Europe, and Asia.
They play an important role in marine ecosystems, serving as predators and prey, and are the subject of ongoing research and conservation efforts.
Phocidae include well-known species such as the harbor seal, the ringed seal, and the elephant seal.

In vivo cell-attached recordings were performed using glass pipettes (∼5-7 MΩ) filled with solution containing the following (in mM): 125 NaCl, 5 KCl, 10 glucose, 10 HEPES, 2 CaCl2, 2 MgSO4, and 0.1 Alexa Fluor 594; pH 7.4). Signals were amplified using an AxoPatch 200B amplifier (Molecular Devices), filtered at 5 kHz, and digitized at 10 kHz. Spikes were recorded using current clamp mode. The frame trigger pulses of ScanImage 4.0 were also recorded and used offline to synchronize individual frames to electrophysiological recordings. After establishment of a low-resistance seal (15-50 MΩ), the orientation, spatial and temporal frequency of the stimuli was quickly optimized for individual neurons using recorded spikes. The optimal grating stimulus was repeated at a reduced contrast to maintain a moderate spiking rate.

PCR verified expression constructs were transformed into either B834 (DE3) or Rosetta(DE3)LysS E. coli (Novagen) in 96-tube format as described for OmniMaxII transformations with 1% w/v Glucose replacing the X-Gal and IPTG reagents in the LB agar. All plates and subsequent media used for the culture of the Rosetta(DE3) LysS cells are identical to those described for B834(DE3) cells but also supplemented with 35 µg/ml chloramphenicol to maintain the pRareLysS plasmid. Plates were incubated for 18 h at 37°C before individual colonies were used to inoculate, 500 µl GS96 (Bio101, QBioGene, Cambridge, UK) supplemented with 0.05% v/v glycerol, 1% w/v glucose and 50 µg/ml carbenicillin in 96-well deep-well plates. The plates were sealed with gas-permeable adhesive seals and shaken at 225 r.p.m. at 37°C for 18 h. For IPTG induction of expression, 50 µl of each overnight culture was then used to inoculate (in four 24-well deep-well plates) 2.5 ml of GS96 supplemented with 50 µg/ml carbenicillin. The diluted cultures were grown at 37°C with shaking at 225 r.p.m., for 3 h before reducing the temperature to 20°C, addition of ITPG to a final concentration of 0.5 mM and shaking for a further 18 h at 20°C. For auto-induction of expression, 50 µl of each overnight culture was used to inoculate (in four 24-well deep-well plates) 2.5 ml of Overnight Express™ Instant TB media (Novagen) supplemented with 50 µg/ml carbenicillin. The diluted cultures were grown at 37°C with shaking at 225 r.p.m., for 3 h before reducing the temperature to 25°C and shaking for a further 24 h at 25°C.
A 1.5 ml aliquot of culture from each well was then transferred to a 2 ml 96-well deep-well plate using a Theonyx robot (Aviso Gmbh, Gera, Germany) and harvested by centrifugation at 6000 g for 10 min at 4°C before decanting of the waste media. Pelleted cells were frozen at −80°C for at least 30 min prior to screening for soluble His6-tag protein expression using either the Theonyx or BR8000 robotic platforms with standard Qiagen Ni-NTA magnetic bead protocols (as per manufacturer's instructions). Proteins purified by elution from the Ni-NTA beads were analysed on SDS-PAGE gels (Criterion™ 10–20% gradient gels—Biorad, Hemel Hempstead, UK or InVitrogen NuPAGE™ Novex 10% Bis-Tris Midi gels with MES buffer system) and visualized with SafeStain™ (InVitrogen). Scale-up and purification of proteins from E. coli were carried out as described earlier (11 (link)).

The ddPCR workflow was described in Figure 1. The TaqMan PCR reaction mixture was assembled from a 2× ddPCR Mastermix (Bio-Rad), 20× primer, and probes (final concentrations of 900 and 250 nM, respectively) and template (variable volume) in a final volume of 20 μL. Each assembled ddPCR reaction mixture was then loaded into the sample well of an eight-channel disposable droplet generator cartridge (Bio-Rad). A volume of 60 μL of droplet generation oil (Bio-Rad) was loaded into the oil well for each channel. The cartridge was placed into the droplet generator (Bio-Rad). The cartridge was removed from the droplet generator, where the droplets that collected in the droplet well were then manually transferred with a multichannel pipet to a 96-well PCR plate. The plate was heat-sealed with a foil seal and then placed on a conventional thermal cycler and amplified to the end-point (40–55 cycles). After PCR, the 96-well PCR plate was loaded on the droplet reader (Bio-Rad), which automatically reads the droplets from each well of the plate (32 wells/h). Analysis of the ddPCR data was performed with QuantaSoft analysis software (Bio-Rad) that accompanied the droplet reader.

For spot size measurements, fresh heparinized blood was spotted onto sheets of Whatman no 1, Whatman 3 MM (Whatman, Maidstone, UK) or glass fibre (Printed Filtermat A, Perkin Elmer, Beaconsfield, UK) filter paper in volumes from 1 μl to 45 μl. For antibody stability and recovery studies, reconstituted blood was prepared by mixing individual African malaria-hyperimmune plasma samples or a hyperimmune plasma pool or a European (non-exposed) negative control pool (all containing heparin) 1:1 by volume with washed European blood group O erythrocytes and immediately spotting 10 μl of this mixture onto Whatman 3 MM or glass fibre filter paper. Spots were allowed to dry at ambient temperature and relative humidity (RH) overnight.
Laboratory-generated blood spots and blood spots from Uganda were stored in individual self-sealing plastic bags (25 cm × 25 cm approx), which were then combined into sets and stored within three further successive plastic bags, the innermost of which contained approximately 3 g of self-indicating silica desiccant gel type III (Sigma). The bags were inspected regularly to confirm that the desiccant remained blue (RH < 20%), and the desiccant replaced if necessary.
Fingerprick blood samples from lower Moshi were collected into EDTA-coated microtainers and as blood spots on Whatman 3 MM paper and transported daily to the laboratory at Kilimanjaro Christian Medical College. Filter papers were refrigerated (2–8°C) in individual plastic bags with silica gel. Plasma was separated from packed red blood cells after centrifugation and stored at -20°C. All samples were assayed within 8 weeks of collection.

Example 12

In another embodiment of Method 2, the second coloring liquid is not mixed with the adhesive solution. First, the zirconia base after surface roughening treatment is colored with the second coloring liquid. When the color of the zirconia base is observed to be consistent with that of the patient's teeth, coloring is stopped, the zirconia base is oven-dried and then soaked in the adhesive solution for 1-20 min, so that the adhesive solution seals the coloring liquid in the pores of the zirconia and fills the pores on the surface of the zirconia to form a protective film on or over the surface of the zirconia ceramic, which prevents bacteria, enzymes and other substances in the oral cavity from entering the pores and causing infection and other hazards. Finally, the zirconia base is taken out, put into a denture sintering furnace, heated up to 1530° C. at a rate of 5° C./min, kept at this temperature for crystallization for 120 min, and then cooled down along with the furnace.
