In a groundbreaking clinical trial, two patients suffering from severe heart failure experienced improvements in their symptoms through an innovative procedure. The clinical trial was conducted by Heartseed, a medical venture associated with Keio University in Tokyo’s Shinjuku Ward.

The procedure involves the transplantation of “cardiomyocyte spheroids” (CM spheroids), spherical clusters of heart muscle cells derived from induced pluripotent stem cells (iPSCs). This development represents a significant step forward in the treatment of heart failure using iPSCs, with plans for practical implementation set for around 2025.

Japanese venture Heartseed has found that treating heart failure with iPSC-derived cardiomyocyte spheroids could achieve sustained tissue regeneration.

Changes to short, repetitive sequences in the genome have been linked to diseases like autism and schizophrenia. New revelations about how such changes increase and decrease gene expression may provide insight into these and other disorders.

For many patients diagnosed with certain types of B-cell lymphoma, leukemia and multiple myeloma, chimeric antigen receptor (CAR) T cell therapy offers an effective treatment option. This cellular therapy is created by extracting a patient’s T cells, modifying them in a lab to identify and attack cancer cells, and returning them to the patient.

The process of creating the CAR T cells can take three to four weeks. Radiation therapy can be a tool to help get a patient through this manufacturing period. This is called bridging therapy.

“Bridging therapy can help control the disease so that a patient can get to the CAR T cell infusion,” says radiation oncologist Penny Fang, M.D. Research from Fang and her colleagues examines the role of bridging therapy for B-cell lymphoma patients receiving CAR T cell therapy. Their latest findings will be presented at the 2023 American Society for Radiation Oncology Annual Meeting.

Eating a type of dietary fiber called chitin evoked an immune response in mice that was linked to better metabolic health.

MDPI uses a print-on-demand service. Your book will be printed and delivered directly from one of three print stations, allowing you to profit from economic shipping to any country in the world. Generally, we use Premium shipping with an estimated delivery time of 7–12 business days. P.O. Boxes cannot be used as a Ship-To Address.

Please note that shipping time does not include the time for placing and processing the order or printing. For this, an additional turnaround time of 10 working days should be expected.

Neurosurgeons can leave the operating room more confident today than ever before about their patient’s brain tumor diagnosis, thanks to the integration of a new system that employs optical imaging and artificial intelligence that are making brain tumor diagnosis quicker and more accurate. This technology is allowing them to quickly see diagnostic tissue and tumor margins in near-real time.

By using a pair of offset beams, researchers are able to generate femtosecond UV pulses that can be aimed directly into a target as a spectroscopic probe.

A hypertriton is a tritium nucleus in which a neutron is replaced by a so-called Lambda hyperon. This type of hypernucleus was first discovered in the 1950s has since been the key focus of numerous studies.

The ALICE collaboration, a large research group that studies the collisions of nuclei inside CERN’s large hadron collider (LHC) in Switzerland, recently measured the lifetime of a hypertriton with remarkable precision. Their paper, published in Physical Review Letters, is a further step forward toward understanding the unique properties of these fascinating nuclear complexes.

“As the first and lightest hypernucleus (i.e., a nucleus that includes a baryon with at least one strange quark) ever identified, the hypertriton holds a special place in nuclear physics,” Maximiliano Puccio, part of the ALICE collaboration, told Phys.org.

An international research team has taken a decisive step toward a new generation of atomic clocks. At the European XFEL X-ray laser, the researchers have created a much more precise pulse generator based on the element scandium, which enables an accuracy of one second in 300 billion years—that is about a thousand times more precise than the current standard atomic clock based on cesium. The team presents its success in the journal Nature.

Atomic clocks are currently the world’s most accurate timekeepers. These clocks have used electrons in the atomic shell of chemical elements, such as cesium, as a pulse generator in order to define the time. These electrons can be raised to a higher energy level with microwaves of a known frequency. In the process, they absorb the microwave radiation.

An atomic clock shines microwaves at cesium atoms and regulates the frequency of the radiation such that the absorption of the microwaves is maximized; experts call this a resonance. The quartz oscillator that generates the microwaves can be kept so stable with the help of resonance that cesium clocks will be accurate to within one second within 300 million years.
