Neuronal and glial proteins detected in the peripheral circulating blood after injury can reflect the extent of the damage caused by blast traumatic brain injury (bTBI). The temporal pattern of their serum levels can further predict the severity and outcome of the injury. As part of characterizing a large-animal model of bTBI, we determined the changes in the serum levels of S100B, neuron-specific enolase (NSE), myelin basic protein (MBP), and neurofilament heavy chain (NF-H). Blood samples were obtained prior to injury and at 6, 24, 72 h, and 2 weeks post-injury from animals with different severities of bTBI; protein levels were determined using reverse phase protein microarray (RPPM) technology. Serum levels of S100B, MBP, and NF-H, but not NSE, showed a time-dependent increase following injury. The detected changes in S100B and MBP levels showed no correlation with the severity of the injury. However, serum NF-H levels increased in a unique, rapid manner, peaking at 6 h post-injury only in animals exposed to severe blast with poor clinical and pathological outcomes. We conclude that the sudden increase in serum NF-H levels following bTBI may be a useful indicator of injury severity. If additional studies verify our findings, the observed early peak of serum NF-H levels can be developed into a useful diagnostic tool for predicting the extent of damage following bTBI.

Playing in new campaign next weekend. Going with a Merfolk Kineticist. GM has approved of class and race. Now according to the rules. Wild Talents can actually be taken at double the listed level it is listed at. Example Wings of Air is listed at 3rd level talent but you can't actually get it is 6th level. I got that although whoever wrote the class screwed up with the wording on that.

Now Form Infusions affecting blasts you can get at the listed level? Example Foe Throw you have to be third level to get it and use it?

You get wild talents at even-numbered levels and you get access to new effect levels at even levels. Getting wings of air at 6th level works. The one that's annoying is infusions, you get new infusions at odd levels but still get access to new effect levels at even levels. So you can get a 3rd level form infusion like foe throw at 7th level if you expand into the same element, or at 9th if you choose a different element to expand into.

Wilm's tumor 1 (WT1), a zinc-finger transcription factor and an epigenetic modifier, is frequently overexpressed in several hematologic disorders and solid tumors, and it has been proposed as diagnostic and prognostic marker of acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS). However, the exact role of WT1 in leukemogenesis and disease progression remains unclear. In this real-world evidence retrospective study, we investigated prognostic role of WT1-mRNA expression levels in AML and MDS patients and correlations with complete blood counts, flow cytometry counts, and molecular features. A total of 71 patients (AML, n = 46; and MDS, n = 25) were included in this study, and WT1 levels were assessed at diagnosis, during treatment and follow-up. We showed that WT1 expression levels were inversely correlated with normal hemopoiesis in both AML and MDS, and positively associated with blast counts. Flow cytometry was more sensitive and specific in distinguishing normal myeloid cells from neoplastic counterpart even just using linear parameters and CD45 expression. Moreover, we showed that a simple integrated approach combining blast counts by flow cytometry, FLT3 mutational status, and WT1 expression levels might be a useful tool for a better prognostic definition in both AML and MDS patients.

Upon its launch in 2019, Angry Birds Dream Blast introduced players to an all new puzzle game style for the Angry Birds flock with matchable items that move fluidly inside levels, rather than being locked to a grid. In addition to this new fluid tap-to-match style, Dream Blast also gave fans of the Angry Birds flock a sneak peek into the early lives of their beloved Angry Birds characters with its delightfully adorable character designs and animations. Three years and 10,000 levels later, the game is still going strong, with new features, events, and a whole lot of new levels being added all the time.

Figure 1. Superior mock-up view of apparatus to discharge black power explosion into cartridge of human blood. A stainless-steel Crossman 12 g CO2 threaded cartridge which contains each sample of human blood was sealed with an nickel plated steel acorn nut was place within a reinforced steel pipe (blast chamber) and capped off to protect the operator from the explosive nail-gun force. The nail gun was positioned above the blast chamber. The chamber was then encompassed in a wooden encasement to position the two chambers in an upright parallel state.

Figure 2. Lateral view of blast chamber. When positioned within the chamber, the rounded end of the CO2 cartridge sticks up approximately  cm out of the chamber to engage with the nail-gun safety sleeve. The re-enforced steel caps allow access to the blast chamber before and after each blast.

In the blast-resistant building industry, we toss around the term "response level" all the time and assume everyone knows what it means. And maybe everyone here does, but the difference between a low response building and a high response building can mean the difference between life and death, so it's worth a closer look, even if you already know the basics.

And, if you don't yet know the basics? it might be a good idea to read up on blast resistant buildings, from cost to common issues, to questions to ask before you buy. We've written the ultimate guide to blast-resistant buildings.

Response levels are ratings established by the American Society of Civil Engineers (ASCE) to predict the extent of repair resources that would need to be devoted to a building after an explosion. Their descriptions include:

Substitute the term "damage level" for "response level," and it gives you an instant picture of what these ratings mean. Given the options of low damage, medium damage and high damage, you obviously don't want to be working in an area that is highly damaged during a blast event.

There are several blast-resistant building designs on the market. When we were asked by one of the industry's key oil refiners to come up with a new one, our first step was to study what was already out there. It came as a surprise few of the existing designs had received low response ratings from ASCE.

We hired Ali Sari, Ph.D., PE, who is one of the few experts in the world with firsthand blast response experience. The resulting RedGuard designs were awarded low to medium response ratings, depending on blast pressures.

There is no regulatory board for blast resistant building design because the technology is still new. This will probably change, but the closest industry criteria currently in place are the recommended practices provided by API, or American Petroleum Institute.

Even with these important guidelines in place, the final proof is in the testing. We detonated 1,250 pounds of high explosive ammonium nitrate/fuel oil charge at a standoff distance of 110 feet from our building. This created a blast strength far in excess of the ratings required to meet ASCE low to medium response standards.

This outlines the importance of taking a closer look at both response level ratings and test results before you buy a blast-resistant building. In response to the question, "Is high response acceptable?" for us, that answer will always be a resounding no. 

We take pride in being the industry leader in blast resistance and in offering the things we've learned as resources for the industry. If you're about to invest money in a blast-resistant building, take some time to read our guide, offering an in-depth look at blast-resistance and the things you should know before you buy.

Traumatic brain injury (TBI) has been linked to mental health disorders and is considered a risk factor for later development of neurodegenerative disorders [31]. Many veterans from the recent conflicts in Iraq and Afghanistan suffer from chronic neurobehavioral syndromes that include post-traumatic stress disorder (PTSD) [31]. Indeed, a striking feature in veterans from the most recent war theaters has been the overlap between a history of blast-related mild TBI (mTBI) and PTSD [17, 31, 115, 134, 140, 141]. While these symptoms may improve, they frequently persist and may worsen with declines driven mainly by worsening PTSD and depression [83]. Although the mechanisms underlying how blast affects human neurobiology are incompletely understood, much evidence suggests that the cerebrovasculature may be particularly vulnerable to blast [112, 131, 133].

Research in rat models of repetitive low level blast exposure has shown that animals exposed to repetitive low-level blast exhibit chronic cognitive impairment and PTSD-related traits that develop over time [30, 33, 100, 101, 123]. These traits include anxiety, enhanced acoustic startle, altered fear learning and impaired cognition in tests such as novel object recognition. Blast-exposed rats thus model many of the features found in human PTSD. A single predator scent challenge delivered 8 months after the last blast exposure induces additional anxiety-related changes that are still present 45 days later [101] suggesting that besides inducing PTSD-related traits blast exposure sensitizes the brain to react abnormally to subsequent psychological stressors.

In the present research, we used a combination of X-ray microcomputed tomography (micro-CT) with computerized morphological analyses to determine the evolution of vascular structural alterations in the brain circulation of blast-exposed rats. Micro-CT scans revealed regional cerebral vascular attenuation as early as 48 h post-blast and cerebral vascular attenuation and disorganization at 6 weeks and 13 months post-blast. Immunohistochemical and histological analyses confirmed the presence of previously reported vascular degenerative processes but also revealed at 13 months post-blast the emergence of a vascular pathology characterized by the detachment of the vasculature from the brain parenchyma with affected arterioles at the core of an enlarged paravascular space. This chronic vascular pathology was associated with perivascular-astrocytic degeneration, vascular attenuation, vascular-associated inflammation and vascular remodeling. Our results further document the evolution of blast-induced neurovascular uncoupling due to astrocytic and vascular degenerative processes and provide evidence for a novel pathology that may affect blood circulation and perivascular flow of CSF and ISF through the glymphatic and IPAD systems in the brain. ff782bc1db
