'Breakthrough' stem-cell patches stabilized a woman's heart as she awaited transplant
Article from Live Science daily newsletter.
By Jess Thomson

A woman with heart failure was kept alive long enough to receive a heart transplant, in part thanks to newly developed stem-cell-derived heart tissue grafts.
A woman with a failing heart has been kept alive with the help of a new "breakthrough" stem-cell technology, scientists report.
The 46-year-old woman experienced a heart attack in 2016 and subsequently developed severe heart failure, in which the heart cannot pump blood efficiently enough to meet the body's needs. The patient was awaiting a heart transplant when she underwent the experimental stem-cell procedure as part of a clinical trial.
During the surgery, the woman's heart was implanted with tiny patches of heart muscle cells, which had been grown from stem cells in a lab. These 10 patches, each comprised of about 400 million heart cells, kept the woman stable until she could receive a heart transplant three months later, according to a paper published Wednesday (Jan. 29) in the journal Nature.
"We now have, for the first time, a laboratory-grown biological transplant available which has the potential to stabilize and strengthen the heart muscle," study co-author Dr. Ingo Kutschka, a heart surgeon at University Medical Center Göttingen in Germany, said in a press conference, Nature News reported.

Unlike many other cell types, such as skin cells, heart muscle cells cannot easily regrow or repair themselves if they are damaged by an insult like a heart attack. Such damage to the heart can lead to heart failure, which affects around 6.7 million adults ages 20 and older in the United States, according to the A Centers for Disease Control and Prevention (CDC). Heart failure was listed as a contributing or primary cause of death on more than 450,000 death certificates in the U.S. in 2022, the CDC reported.
Over half of people with severe heart failure die within a year unless they receive a heart transplant, but there are limited donor hearts available, Nature News reported.
To supplement these limited heart transplants, scientists have experimented with transplanting heart muscle cells instead. In the new Nature paper, the researchers describe a method of growing heart tissue from stem cells known as induced pluripotent stem cells (iPSCs). Scientists create these stem cells by gathering normal adult cells and then reprogramming them back into a "pluripotent" state, from which they can develop into almost any cell type in the body.
The scientists encouraged these iPSCs to develop into heart muscle cells and connective tissue in the lab; the researchers then mixed the resulting tissue with collagen to create tiny patches that could be implanted onto the surface of the heart.
"The graft is basically outside of the heart," Dr. Jianyi Zhang, an iPSC bioengineering expert at the University of Alabama at Birmingham who was not involved in this study, told Nature. "It's quite a breakthrough."
The scientists first tested similar patches on rhesus macaque monkeys (Macaca mulatta) with heart failure; the patches tested on monkeys were grown with monkey stem cells. Six months later, several of the monkeys grew thicker heart walls that could pump up to 10% more blood per heartbeat than a group of untreated monkeys.
During the patch procedure, the monkeys were all given immunosuppressant drugs, to prevent their immune systems from rejecting the grafts. Additionally, none of the monkeys developed tumors or irregular heartbeats, which had been a problem in similar studies conducted in the past.
The success of the monkey trial enabled the trial in human volunteers, one of whom was the 46-year-old woman. After the woman underwent her heart transplant, the researchers examined her old heart and saw that the implanted patches had grown minuscule blood vessels, indicating that they were receiving blood and oxygen from the body.

"This is clear now, that you can add muscle to the failing heart, and that we can do that without safety concerns," study co-author Wolfram-Hubertus Zimmermann, a pharmacologist at University Medical Center Göttingen, said in the press conference.
The eventual hope is that this approach will help people stay alive for long enough to receive a donor heart; it's not intended as a complete alternative to transplants.
In an ongoing trial, the scientists have so far implanted the patches in 15 other people. They are also experimenting with more macaques to find a way to minimize the use of immunosuppressant drugs, which help prevent rejection but can leave a patient vulnerable to infection and other health problems.

I like flowers. It is difficult to find good flowers in summer, but we can still find fresh flowers in stores. There are many different small, interesting objects in nature for macro photography. I took this picture with Sigma105mm macro lens, it has image stabilization, very sharp and compact lens. I don’t use flash for macro photography because I don’t like highlight on the objects. I took one shot and didn’t use photo stacking in photoshop. Rose are big flowers and are easy to photograph. Smaller flowers are difficult to photograph. Have a wonderful day!
Feeling better, really wants to go out.

Na Serra do Marão, um pinheiro-de-casquinha (Pinus sylvestris) demonstra a adaptabilidade da espécie às condições agrestes do norte de Portugal. Este exemplar, típico de florestações em serras como o Gerês e o Marão, onde a espécie se naturalizou, exibe uma casca espessa e fendida na base, evoluindo para tons laranja-avermelhados em "casquinhas" no topo. Atingindo altitudes entre os 600 e os 1400 metros, o pinheiro-silvestre tolera geadas e solos pobres, prosperando em substratos xistosos e graníticos. A sua presença é essencial para o ecossistema, oferecendo abrigo à fauna e desempenhando um papel crucial na estabilização dos solos e na regulação hídrica, alimentando nascentes. A morfologia retorcida dos ramos denota a exposição aos ventos, enquanto a presença de líquenes nos troncos sugere boa qualidade do ar. No final de novembro, a vegetação prepara-se para o inverno, numa paisagem outrora marcada por atividades pastorícias e agora valorizada pelo turismo de natureza.
In the Marão Mountains, a Scots pine (Pinus sylvestris) demonstrates the species' adaptability to the harsh conditions of northern Portugal. This specimen, typical of forests in mountain ranges such as Gerês and Marão, where the species has become naturalized, has thick, cracked bark at the base, evolving into reddish-orange tones in “cones” at the top. Reaching altitudes between 600 and 1400 meters, the Scots pine tolerates frost and poor soils, thriving on schistose and granitic substrates. Its presence is essential to the ecosystem, providing shelter for wildlife and playing a crucial role in soil stabilization and water regulation, feeding springs. The twisted morphology of the branches denotes exposure to the winds, while the presence of lichens on the trunks suggests good air quality. At the end of November, the vegetation prepares for winter, in a landscape once marked by pastoral activities and now valued for nature tourism.

Since its completion in 1933, the U.S. Post Office and Courthouse has been an important landmark in Alexandria, the county seat of Rapides Parish, Louisiana. Designed by Shreveport architect Edward F. Neild, under the supervision of the Office of the Supervising Architect of the Treasury Department, the building is an excellent example of Depression-era Art Deco architecture. It was not only designed to serve a federal function but to express the permanence and presence of the federal government in the cities and communities in which the buildings were being constructed. However, the construction of the Alexandria U.S. Post Office and Courthouse in 1932-1933 was not simply a reflection of the growing needs of a city or federal court. As one of more than 1,300 public buildings built under the auspices of the Office of the Supervising Architect of the Treasury Department during the early 1930's, the Alexandria building was an example of the government's use of federal construction projects to stimulate employment during the Depression. From 1926 to 1931, a series of legislation was enacted that culminated into this massive public building program. The Public Buildings Act of 1926 served as the catalyst, authorizing the construction of a number of buildings in communities previously without federal buildings. In 1928, appropriations allotted under the 1926 act were increased in response to U.S. Post Office and Department of the Treasury reports indicating a need for more space. As the effects of the Depression began to be felt all over the country, the government released additional funds in 1930 and 1931 for public building projects. During 1931, the Federal Employment Stabilization Act was passed to further stimulate the economy. This act permitted the president and congress to authorize additional appropriations for construction projects in order to facilitate employment. The 1930 and 1931 appropriations, coupled with the Federal Stabilization Act, were reflective of how the government used public works projects to combat the early years of the economic depression.
On May 18, 2000, the U.S. Post Office & Courthouse in Alexandria, LA was found to be eligible for listing on the National Register of Historic Places for its association with the federal construction programs designed to relieve the economic emergency of the Depression years (criteria A) and as an excellent example Art Deco architecture (criteria C) used in the design of public buildings during the 1930's. All of the information above (and much more) was found on the original documents submitted for listing consideration with the National Register and can be viewed here:

A lovely dahlia from the Dahlia Garden at Point Defiance Park in Tacoma, WA, 2019. The roses are going strong as we enter the month of June and the dahlias won't be too far behind. A great time of year after the long, wet winter.
A fun one to shoot with the 70-200E lens at 200mm. Always a challenge to nail focus and get a sharp one with a bit of wind. With my best efforts the bee was still a little soft due to motion blur, so I took it into Topaz Sharpen AI as a plugin from PS. I used the Stabilize mode then applied it selectively to just the bee area with the brush in PS. Real easy to do using a black mask and white brush at low opacity.

So, I could use a stabilized lens given that I shoot out of train windows and drink too much coffee. So when my friend Sudi went medium format I was offered the kit lens off of his 5D Mark II, which I also ended up buying later. Here is the lens on its first train trip, nailing a shot that had eluded me for years.
In the early 1900's "His Master's Voice" record stores were launched in the UK, and had as its logo a dog listening to a gramophone. The Radio Corporation of America (RCA) liked the logo so much they licensed its use exclusively in the USA. When they opened a plant in Albany, the dog -- named "Nipper" -- was placed on the roof.
So, from the train there is only one gap in the trees where you can get a clean shot of the factory (note the trees on either side of the image; now imagine them moving!). Worse, it is on a curve and is during the approach to Albany station, so the train is usually going slowly at a speed where it's usually rocking: hence the need for an IS lens. I knew I had this when I took it, and immediately justified the purchase for me! (I do have another shot of this, captured in infrared on my 350D amazing with my even older EF 100-300 5.6L -- and no image stabilization to boot! Over the years I've not been able to repeat that shot -- until this one!!)

Have a great weekend
19 January 2021: The 7-day rolling average for people testing positive for the virus stabilizes and the number of people being hospitalised with the virus continues to fall slowly but surely. The same is true of the number of people with the virus that are dying. On average during the week to 15 January 2,017 people a day tested positive for the coronavirus, that is down 1% on the week. Meanwhile, several outbreaks of the British mutation of the virus have been reported. In one case it has been confirmed that the source of the infection is people that had travelled during the Christmas holiday and not stuck to the rules concerning quarantine on their return. The result is that thousands are quarantined due to the negligence by a few. The question of how to keep out more contagious coronavirus variants of the virus is what is now preoccupying the country’s politicians. Waiting for the beneficial seasonal impact on the spread of the virus and the effect from groups immunity via people who have had the virus and via vaccinations I continue my corona walks. On display today is a pleasing urban alignment that I pictured alongside the river Scheldt – Ghent, Belgium.

Taking photographs of a local colony of Rabbits has become a bit of a passion recently. There are around 100 Rabbits that run around and feed on a local field that is surrounded by thick bushes, as soon as you step foot on the field they all run for cover so photographing them has become a game of stealth!
To take this photo i had to climb quite a big fence which got a passer by quite concerned but they were ok when i said I'm just taking photos! After that i could approach the field from an angle where i didn't scare too many Rabbits off, i then lay down flat and waited for them to come out of hiding.
The above photo was taken with the Rabbits about 5 metres away from me, i've found the canon 55-250mm great for taking these photos, even though i've got a Sigma 70-300, the image stabilization on the canon lens more than makes up for a bit more zoom.
I can see me going back to this field a lot over the summer, I love the character of the Rabbits and i think there are some good opportunities for better light just before sunset.
Putting on a show for me...check out the collage below... I dug out my cheap zoom lens that i rarely use because it has no stabilization...this day i was pleased that it did as good a job as it did! I may use it more often! On explore at #73 Aug. 20/09

I am just posting this to show the incredible image stabilization of the OM-D. this is a one second exposure handheld. I don't have steady hands. I challenge any Nikon or Canon or Panasonic with the lens based stabilization to reproduce a one second exposure like this without a tripod or support. I didn't even prop up my arms against my chest. This is just a normal quick snapshot. I even turned the camera sideways.
In 1897, the city began stabilizing and expanding the site for Chicago Avenue Park with landfill. Landscape improvements commenced three years later. It was expanded in 1907 by improving city land just west of the park, and the next year was officially named Lake Shore Playground. An armory was constructed at the west end of the park during World War It. The current fieldhouse on the park's eastern border replaced an older structure in 1963. The armory to the west was demolished in the 1990s, and the Museum of Contemporary Art is now on the site.
Continuing my recovery from back surgery six weeks ago, we walked 7/10ths of a mile to Lake Shore Park and took a lap around the track. I resume physical therapy in two days; now that the pain is gone, this should be an interesting challenge.
