Senate Readiness Panel Denies Pentagons BRAC Request

first_img Dan Cohen AUTHOR The Defense Department would be prohibited from holding a round of base closures, under the portion of the fiscal 2016 defense authorization bill marked up Tuesday by the Senate Armed Services’ Readiness Subcommittee. “At a time when the department cannot afford to fully fund … readiness requirements, I do not support giving the department the authority to pursue a BRAC round,” said Subcommittee Chair Kelly Ayotte (R-N.H.), reported CQ Roll Call.The panel’s rejection of the Obama administration’s request to hold a BRAC round in 2017 was not a surprise as Ayotte has made her opposition clear in recent years. She pointed to the potential for a new round to incur significant upfront costs, as the last one did, in explaining her stance at a hearing of the subcommittee in March.The text of the legislation is not expected to be available until the full committee completes its markup. Its deliberations begin this morning and are expected to run until Thursday night or beyond.The measure also contains language to reform DOD’s weapons acquisition process. Ayotte said the proposals are similar to those in the House bill but did not discuss its specific provisions, according to the story.“In this era of growing threats and shrinking defense budgets, the old methods of acquisition and … acquisition overruns are no longer sufficient,” Ayotte said.last_img read more

DC Bill Would Help Returning Citizens Start Businesses

first_imgD.C. Council member Vincent OrangeD.C. Council member Vincent Orange (D-At-Large) held a hearing recently on a bill he introduced that would help returning citizens learn skills to start and operate businesses.The hearing for the bill, which would create a $10 million operating fund, was held on Jan. 28. Called “The District of Columbia Incarceration to Incorporation Entreprenuership Program Act of 2015,” Orange’s bill calls for the Department of Employment Services and the Department of Small and Local Business Development to set up the program.The legislation calls for the University of the District of Columbia and its community college to offer courses to returning citizens on business subjects and GED attainment, and provide scholarships and grants to help pay for the classes. Orange said keeping returning citizens positively engaged is the way to avoid criminal activity.“Statistics have shown that within three years of coming home from prison, returning citizens will be re-arrested,” Orange said. “Stable employment is the key to keeping people out of prison and owning a business can be a part of that.”There are an estimated 60,000 District residents with criminal records. Studies and testimonies from returning citizens reveal that even though the city has tolerant laws and public policy towards them, it is difficult for returning citizens to find employment. Skeptical employers have cited possible criminal activity and not wanting to deal with stigmatized employees as reasons for not hiring returning citizens.Orange said returning citizens with stable jobs have a recidivism rate of only 7 percent as opposed to 51.8 percent according to U.S. Bureau of Justice statistics. The council member said that Oklahoma and Pennsylvania have programs similar to one he is proposing and they are considered national models of success.Orange’s legislation has the support of D.C. Council member Yvette Alexander (D-Ward 7). D.C. Council member Charles Allen (D-Ward 6) likes the idea but is worried about program implementation. “The incarcerated population is the hardest to reach,” Allen said. “I don’t think DOES serves returning citizens well and I want to make sure that DOES works for everyone. There is no shortage of really good intentions in this city and I hope that it reaches individuals who can be set up for success.”A number of witnesses testified on Orange’s bill. No one voiced opposition to Orange’s concept but some had concerns about implementation and focus. “The bill could be improved by emphasizing cooperative businesses and should provide co-op specific business training,” said Eugene Puryear, director of field operations for the advocacy organization Justice First. Puryear wants Orange’s bill to include provisions to appoint a returning citizen on a panel that would oversee the program, to require a review by the council after its fifth year, and provide “a hard cap [on funding the program] on the initial appropriation [to] encourage program effectiveness and community input.”Debra Rowe, the executive director of Returning Citizens United, testified in support of Orange’s bill, but said more support is needed for those participating in the program. “To start a business in the District of Columbia, you have to pay a lot of fees,” Rowe said. “The people that the legislation is designed to help generally cannot pay the fees to the city agencies that are needed to get their businesses going.”Rowe doesn’t want the program Orange proposes to become “another certification for returning citizens.”“We have every certification that you can think of but we can’t get the jobs,” she said. “I also think that businesses that are run by returning citizens that are successful certified business enterprises should mentor those who want to go into business.”last_img read more

Optimal stem cell reprogramming through sequential protocols

first_img Back in 2006, researchers in Japan were able to effectively generate stem cells from skin cells without the need for oocytes (eggs) or other embryonic cells. By expressing the four transcription factors, Oct4, Sox2, KLF4 and c-Myc, they could generate cells that, at least in theory, could turn into any other kind of cell. Unfortunately, not only the overall yield of viable stem cells was low, the “rejuvenated” cells that were able to be extracted were generally unsuitable for subsequent patient treatment. The problem is that even when transplanting stem cells obtained from a person’s own skin, immune rejection or tumor formation still occurred. This disharmony results from the fact that the immune system, while trained over a lifetime, can be confused by the “dissonance” in expression of youthful protein isoforms, particularly when encountered astride those of more adult cells. By inducing the expression of all four transformation factors at different times, the Chinese researchers eventually hit upon the optimal sequence. In a nutshell, introducing a combination of Oct4 and Klf4 first, followed later by c-Myc, and then finally Sox2, the maximal yield could be obtained. They were surprised to find that this sequential protocol activated an epithelial-to-mesenchymal (EMT) transition, which was then followed by a delayed reverse (MET) transition. It had been known for some time that in mouse fibroblasts, reprogramming to the pluripotent stem cell state begins by going through a MET conversion. Therefore finding upregulation of the proteins SLUG and N-cadherin, factors generally associated with an EMT, was not anticipated.In embryogenesis, cells interconvert between epithelial and mesenchymal phenotypes as they lay out the basic body plan. In the epithelial state, cells possess inherent polarity and show preferential adhesion, while in the mesenchymal state, these properties are lost as cells becomes migratory and invasive. This game of run-the bases is recapitulated as more option-constrained cells later rough out the critical form of each organ. Each time cells alights in either camp, they express part of an overlapping subset of various state indicators, but their genetic arrangements are never quite the same. The authors looked at a few additional factors that might help explain the appearance of a brief mesenchymal state in the sequential procedure. By applying TGF-beta to the simultaneous factor expression protocol early on, they were able to mimic the appearance of the mesenchymal state. This was found to be accompanied by an enhancement in the reprogramming yield, but the effect disappeared when the TGF-beta was applied using a 12-day treatment protocol.TGF-beta is a whole new can of worms since it is expressed by many cells and does many things, even opposite things in different cells. It is traditionally termed a cytokine, although the distinction between that and a hormone is becoming increasingly blurred. Generally hormones are active at nanomolar concentrations in the blood and vary by less than an order of magnitude. Cytokines by contrast often circulate at less than picomolar concentration and ramp up 1000-fold when called upon during injury or infection.Capturing the essential behavior of the thousands of downstream regulators or even just four transcription factors, is just not realistic with a flowchart or state diagram. Beyond a certain level of complexity, if the transition probabilities are too low, or the branch points and exceptions too numerous, new constraints are needed before any sensible algorithmic description might be attempted. In the absence of any such obvious constraints, the authors hypothesized that while multiple pathways exist for conversion between epithelial-mesenchymal states, some are shorter or easier to access than others. They believe that their sequential recipe tips the balance towards a brief mesenchymal state which ultimately leads to a better stem cell yield.

From taming cancer, to providing compatible cell banks for replacement organs, knowledge of how cells interconvert between stable points on the complex cellulo-genetic landscape will deliver to the doctor the same mastery the programmer now holds over bits. While researchers often speak of “reprogramming” cells, most recipes today consist only of a crude and partial ingredient list, with little consideration of sequence, quantity or prior state. We recently took stock of the latest in stem cell technology and reviewed the four major factors used to revert adult cells back into omnipotent progenitors. We also just reported on further attempts to rigorously define appropriate level of factors to supply. Researchers from China have now reported that stem cell generation can be regulated by the precise temporal expression of these factors. Publishing in the journal Nature Cell Biology, they show that the efficiency and yield of stem cells can be optimized by controlling the sequencing of the transforming factors, and furthermore provide a theoretical exploration of the possible mechanisms going on behind the scenes.

Here we report that a sequential introduction protocol (Oct4–Klf4 first, then c-Myc and finally Sox2) outperforms the simultaneous one. Surprisingly, the sequential protocol activates an early epithelial-to-mesenchymal transition (EMT) as indicated by the upregulation of Slug and N-cadherin followed by a delayed mesenchymal-to-epithelial transition (MET). An early EMT induced by 1.5-day TGF-β treatment enhances reprogramming with the simultaneous protocol, whereas 12-day treatment blocks reprogramming. Consistent results were obtained when the TGF-β antagonist Repsox was applied in the sequential protocol. These results reveal a time-sensitive role of individual factors for optimal reprogramming and a sequential EMT–MET mechanism at the start of reprogramming. Our studies provide a rationale for further optimizing reprogramming, and introduce the concept of a sequential EMT–MET mechanism for cell fate decision that should be investigated further in other systems, both in vitro and in vivo.
