Buster Posey has known only one manager since making his debut with the Giants a decade ago. While it's hard for him to envision playing for someone other than Bruce Bochy, he wasn't surprised to hear about his longtime manager's plans to retire after the 2019 season.

The life cycle of malaria parasites in both their mammalian host and mosquito vector consists of multiple developmental stages that ensure proper replication and progeny survival. The transition between these stages is fueled by nutrients scavenged from the host and fed into specialized metabolic pathways of the parasite. One such pathway is used by Plasmodium falciparum, which causes the most severe form of human malaria, to synthesize its major phospholipids, phosphatidylcholine, phosphatidylethanolamine, and phosphatidylserine. Much is known about the enzymes involved in the synthesis of these phospholipids, and recent advances in genetic engineering, single-cell RNA-Seq analyses, and drug screening have provided new perspectives on the importance of some of these enzymes in parasite development and sexual differentiation and have identified targets for the development of new antimalarial drugs. This Minireview focuses on two phospholipid biosynthesis enzymes of P. falciparum that catalyze phosphoethanolamine transmethylation (PfPMT) and phosphatidylserine decarboxylation (PfPSD) during the blood stages of the parasite. We also discuss our current understanding of the biochemical, structural, and biological functions of these enzymes and highlight efforts to use them as antimalarial drug targets.

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...

It is definitely a make-or-break season for those trying to balance career and COVID-19 at home. For some, it is the ideal time to reconnect with themselves, family members and get creative with work. While with others, the cookie crumbles and they...

Human but not mouse islets transplanted into immunodeficient NSG mice effectively accumulate lipid droplets (LDs). Because chronic lipid exposure is associated with islet β-cell dysfunction, we investigated LD accumulation in the intact human and mouse pancreas over a range of ages and states of diabetes. Very few LDs were found in normal human juvenile pancreatic acinar and islet cells, with numbers subsequently increasing throughout adulthood. While accumulation appeared evenly distributed in postjuvenile acinar and islet cells in donors without diabetes, LDs were enriched in islet α- and β-cells from donors with type 2 diabetes (T2D). LDs were also found in the islet β-like cells produced from human embryonic cell–derived β-cell clusters. In contrast, LD accumulation was nearly undetectable in the adult rodent pancreas, even in hyperglycemic and hyperlipidemic models or 1.5-year-old mice. Taken together, there appear to be significant differences in pancreas islet cell lipid handling between species, and the human juvenile and adult cell populations. Moreover, our results suggest that LD enrichment could be impactful to T2D islet cell function.

Braves manager Brian Snitker joked that he could almost detect a smile as he shared a phone conversation with Nick Markakis after the stoic outfielder re-signed with the club in January. Snitker and others actually saw that smile on Tuesday morning, when Markakis reported to Spring Training to begin his fifth season with the Braves and attempt to push the club past the rebuild he positively enriched through his leadership.

Frank Robinson, a trailblazing figure who was Major League Baseball's first African-American manager and one of its greatest players during a career that spanned 21 seasons, died Thursday after a prolonged illness. He was 83.

Like so many pitchers in Major League camps, Orioles hurlers have extra sets of eyes on them this spring. The Edgertronic cameras, perched on tripods, are set about a stride's length beyond the backfield bullpen mounds at the club's Ed Smith Stadium complex, as conspicuous as the coaches standing cross-armed behind them.

Pitch clocks are set to make their Spring Training debuts this week, and it will be in games featuring hordes of players for whom playing on a timer is nothing new.

Middle East respiratory syndrome (MERS) is an acute viral respiratory tract infection caused by the novel betacoronavirus. Cases have been limited to the Arabian Peninsula and its surrounding countries, and to travellers from the Middle East or their contacts. The clinical spectrum of infection varies from no symptoms or mild respiratory...

Underneath all of our civilisation and science, we’re still primates - and the connection between patient and doctor can be reinforced by simply taking a hand. Robin Youngson, cofounder of hearts in healthcare, and Mitzi Blennerhassett, who has written extensively on patient engagement, have co-authored an editorial calling for the humanisation...

Persistent physical symptoms are common and include those symptoms that last at least three months and are insufficiently explained by a medical condition after adequate examination and investigation. Observational studies in primary care report that women, especially those aged 35-45 years, more commonly present with these symptoms. In this...

Each individual’s grief process is unique, when confronted with the death of a loved one, most people experience transient rather than persistent distress - however 10% of bereaved individuals, with an increased risk following the death of a partner or child and loss to unnatural or violent circumstances, experience prolonged grief disorder. In...

Loss of a loved one can be very painful. When seeking support, some people turn to their doctor. Because of their pivotal role in the community, physicians can provide excellent support for bereaved people and can often direct them to additional resources. Katherine Shear, a physician, and Stephanie Muldberg, a bereaved mother, join us to discuss...

A new Rapid Recommendation from The BMJ suggests that for pregnant women, they may wish to avoid certain antiviral treatments for HIV. This recommendation differs from the WHO's, and to discuss why that is, and what makes that difference important, we're joined by Reed Siemieniuk, a physician and methodologist from McMaster University, and Alice...

Acute respiratory distress syndrome was first described in 1967 and has become a defining condition in critical care. Around 40% of patients with ARDS will die, and survivors experience long term sequelae. No drug treatments exist for ARDS, however good supportive management reduces harm and improves outcome. In this podcast, John Laffey,...

Winter pressures on NHS services have kicked in a little bit earlier than usual. So here to discuss that, and also the issue of how local NHS leaders can support staff in times of extreme pressure. Discussing that with Rebecca Coombes, The BMJ’s head of news and views, are Matthew Inada-Kim, a consultant in acute and general medicine at...

When tackling societal problems - like the opioid epidemic in the US - there are two ways of approaching it. One is to reduce demand - by organising treatment programmes, or reducing the underlying reasons why people may become addicted in the first place - but that’s hard. So governments often turn to the other route - reducing supply - and...

Getting feedback from people who use NHS services is essential to assessing their value - and improving their quality. Hospitals and general practices widely post information about patient's satisfaction with their services on their websites, but approach tells us little about how feedback changes things on the ground . In this podcast, James...

More than ½ of patients leave hospital with changes to four or more of their long-term medications - but how appropriate are those changes? New research published on bmj.com looks at antihypertensive medication prescription changes to try and model that - and found that more than half of intensifications occurred in patients with previously well...

There is very little guidance on withdrawing or tapering opioids in chronic pain (not caused by cancer). People can fear pain, withdrawal symptoms, a lack of social and healthcare support, and they may also distrust non-opioid methods of pain management. This can mean that patients receive repeat opioid prescriptions for extended periods of...

Diabetes is synonymous with sugar, but diabetes insipidus, "water diabetes", can't be forgotten. Between 2009 and 2016, 4 people died in hospital in England, when lifesaving treatment for the condition was not given. In this podcast, we hear some practical tips for non-specialists to aid diagnosis, and how patients should be managed during...

On the 7th of June, 1753, Dr Archibald Cameron was executed at Tyburn. "The body, after hanging twenty minutes, was cut down: it was not quartered; but the heart was taken out and burnt. " 250 years later, his sixth great grandson, Robert Syned found himself deeply involved in the process of execution, as an expert witness in a case about the use...

Looking after a young child is hard enough, but when that child has learning difficulties and displays challenging behaviour - the burden on parents can be extreme. That behaviour may prompt a visit to the doctor, and in this podcast we’re talking about how parents can be supported in that - what services are available. We’ll also be discussing...

In 2001, Gottfried Hirnschall joined the WHO to work on the global response to HIV/AIDs, 18 years later he just retired as the director of WHO’s department for HIV and Hepatitis. The intervening period, almost half the time we’ve been aware of the disease the fight against the infection has been characterised by scientific breakthroughs, and...
