Steven Duggar and Ryder Jones continue to take steps forward in their rehab, as they were both cleared to take batting practice on the field Friday for the first time since their September surgeries.

Many chemicals and cellular processes cause oxidative stress that can damage lipids, proteins, or DNA (1). To quickly sense and respond to this ubiquitous threat, organisms have evolved enzymes that neutralize harmful oxidants such as reactive oxygen species and electrophilic compounds (including xenobiotics and their breakdown products) in cells.These antioxidant enzymes include GSH S-transferase (GST),2 NADPH:quinone oxidoreductase 1, thioredoxin, hemeoxygenase-1, and others (2, 3). Many of these proteins are commonly expressed in cells exposed to oxidative stress.The antioxidant response element (ARE) is a major regulatory component of this cellular stress response. The ARE is a conserved, 11-nucleotide-long DNA motif present in the 5'-flanking regions of many genes encoding antioxidant proteins. The laboratory of Cecil Pickett (Fig. 1) at the Merck Frosst Centre for Therapeutic Research in Quebec discovered ARE, a finding reported in the early 1990s in two JBC papers recognized as Classics here (4, 5).jbc;295/12/3929/F1F1F1Figure 1.Cecil Pickett (pictured) and colleagues first described the ARE motif, present in the 5' regions of many genes whose expression is up-regulated by oxidative stress and xenobiotics. Photo courtesy of Cecil Pickett.ARE's discovery was spurred in large part by Pickett's career choice. After completing a PhD in biology and a 2-year postdoc at UCLA in the mid-1970s, he began to work in the pharmaceutical industry.Recruited to Merck in 1978 by its then head of research and development (and later CEO), Roy Vagelos, “I became interested in how drug-metabolizing enzymes were induced by various xenobiotics,” Pickett says.According to Pickett, Vagelos encouraged researchers at the company...

Oversimplification and lack of evidence stigmatise people with mental illness and impede prevention efforts, says Simon Wessley, professor of psychiatry at King's College London, in an editorial published on thebmj.com. Read the full editorial: http://www.bmj.com/content/354/bmj.i4869

We have had two articles published recently on bmj.com, looking at drug prevention of HIV; PeP - Post-exposure Prophylaxis and PreP - Pre-exposure Prophylaxis, neither prevent the virus from entering the body, but they do prevent the infection from taking hold. There are lots of questions that doctors have about these - what are the risk...

There comes a tipping point in all campaigns when the evidence is overwhelming and the only way to proceed is with action.

“Our nation’s veterans deserve the best.” Those were the words of ADA President Chad P. Gehani following his Jan. 7 visit to the Orlando VA Healthcare System’s dental clinic.

The Dental Quality Alliance will help dentists learn more about how quality measure domains can be best used to drive quality improvement at the practice level through a free webinar in March.

Titled “Compendium of Innovations in Oral Health Service Delivery,” the 64-page digital booklet features organizations from across the country that have found success through varied measures in expanding oral care to underserved populations.

The ADA is streaming a free webinar April 14 intended to help dentists jump-start their recovery process during and after the COVID-19 pandemic.

American Dental Association President Chad P. Gehani has assembled an advisory task force to oversee the ADA’s development of tools for dentists as they bounce back from the effects of practice restrictions and closures caused by the COVID-19 pandemic.

Association staff and members of the ADA Advisory Task Force on Dental Practice Recovery are aware and working diligently in addressing members’ concerns over the limited availability of certain personal protective equipment items.

Everyday Health is gathering the responses of several professionals of the top 5 questions they get regarding ADHD. They asked me to participate. The following are the questions and my answers. Check in with Everyday Health next week to see the compilation of responses.

1. Why are there so many theories about the causes of ADHD? What are the most common?

2. How can you explain the value of treatment to resistant parents? For example, “I survived my childhood with ADHD --and I was never diagnosed or treated. Why does my child need ADHD treatment?”

Often children with ADHD have gaps in their education. As they are in and out of focus each day, they miss key points in instruction. As new skills build upon old skills, it can be more and more difficult to learn new tasks where there are gaps in the foundation. This difficulty can make focusing even more difficult, further compounding the problem. Treatment can help reduce or prevent this cycle.

3. What role does a child’s school have in helping him or her with ADHD?

4. Are the medications recommended for ADHD safe for children? What are the potential dangers?

The perjury trial of I. Lewis "Scooter" Libby goes to the jury this week. The case speaks to several issues -- how the Bush administration deals with critics of the war in Iraq, and the games that Washington's reporters and politicians play with each other. As far as the jury is concerned, however,...

Let's say there are 10 houses on your street and a giant pothole develops right in the middle of the block. Everyone benefits if the pothole gets fixed, but that might require multiple calls to municipal authorities and a lot of hassle. Since every resident benefits even if he or she does nothing...

Racism makes our economy worse -- and not just in ways that harm people of color, says public policy expert Heather C. McGhee. From her research and travels across the US, McGhee shares startling insights into how racism fuels bad policymaking and drains our economic potential -- and offers a crucial rethink on what we can do to create a more prosperous nation for all. "Our fates are linked," she says. "It costs us so much to remain divided."

Abstract:
We study the problem of recovery of matrices that are simultaneously low rank and row and/or column sparse. Such matrices appear in recent applications in cognitive neuroscience, imaging, computer vision, macroeconomics, and genetics. We propose a GDT (Gradient Descent with hard Thresholding) algorithm to efficiently recover matrices with such structure, by minimizing a bi-convex function over a nonconvex set of constraints. We show linear convergence of the iterates obtained by GDT to a region within statistical error of an optimal solution. As an application of our method, we consider multi-task learning problems and show that the statistical error rate obtained by GDT is near optimal compared to minimax rate. Experiments demonstrate competitive performance and much faster running speed compared to existing methods, on both simulations and real data sets.

Abstract:
We show how to exactly reconstruct the block structure at the critical line in the so-called Ising block model. This model was recently re-introduced by Berthet, Rigollet and Srivastava in [2]. There the authors show how to exactly reconstruct blocks away from the critical line and they give an upper and a lower bound on the number of observations one needs; thereby they establish a minimax optimal rate (up to constants). Our technique relies on a combination of their methods with fluctuation results obtained in [20]. The latter are extended to the full critical regime. We find that the number of necessary observations depends on whether the interaction parameter between two blocks is positive or negative: In the first case, there are about $Nlog N$ observations required to exactly recover the block structure, while in the latter case $sqrt{N}log N$ observations suffice.

Abstract:
It is frequently of interest to identify simultaneous signals, defined as features that exhibit statistical significance across each of several independent experiments. For example, genes that are consistently differentially expressed across experiments in different animal species can reveal evolutionarily conserved biological mechanisms. However, in some problems the test statistics corresponding to these features can have complicated or unknown null distributions. This paper proposes a novel nonparametric false discovery rate control procedure that can identify simultaneous signals even without knowing these null distributions. The method is shown, theoretically and in simulations, to asymptotically control the false discovery rate. It was also used to identify genes that were both differentially expressed and proximal to differentially accessible chromatin in the brains of mice exposed to a conspecific intruder. The proposed method is available in the R package github.com/sdzhao/ssa.
