This evolution of the prefilled syringe brings a totally innovative design that eliminates any break loose force and any need for silicone oil. There is no head space and no specific injection angle, while keeping a standard luer port and an easy handling. At the same time, the original design allows a large safe printing area, the lowest contact of product with surface and an effective autodisabling feature to ensure a single use.

Antimicrobial touch surfaces have been introduced in healthcare settings with the aim of supporting existing hygiene procedures, and to help combat the increasing threat of antimicrobial resistance. However, concerns have been raised over the potential selection pressure exerted by such surfaces, which may drive the evolution and spread of antimicrobial resistance. This review highlights studies that indicate risks associated with resistance on antimicrobial surfaces by different processes, including evolution by de-novo mutation and horizontal gene transfer, and species sorting of inherently resistant bacteria dispersed on to antimicrobial surfaces.

Nowadays, due to the growing problem of antibiotic resistance, the development of novel anti-ARB therapeutic strategies has been of great interest. Although certain strategies discussed in this review have shown promising potential in clinical or preclinical studies, the complexity of their structure and physiology may protect bacteria from single treatments. The combination of these strategies and flexibility in their use could hold more promise for future anti-ARB treatments. For instance, in order for the antibody–antibiotic conjugate (DSTA4637S) to kill intracellular reservoirs of S. aureus, the binding of the antibody to S. aureus is required.

It might be possible to effectively cure the most common form of asthma by using genetically engineered cells to kill off the rogue immune cells that trigger asthma attacks, a study in mice suggests. But making this kind of treatment affordable will be a major challenge, and its risks mean it would probably be given only to those who get life-threatening asthma attacks. “For most asthma patients, an inhaler is probably enough, however, approximately 250,000 people die from severe asthma annually,” says Min Peng at Tsinghua University in Beijing, China. “[This] could be an option for those patients.”

Chimeric antigen receptor (CAR) designs that incorporate pharmacologic control are desirable; however, designs suitable for clinical translation are needed. We designed a fully human, rapamycin-regulated drug product for targeting CD33+ tumors called dimerizaing agent–regulated immunoreceptor complex (DARIC33). T cell products demonstrated target-specific and rapamycin-dependent cytokine release, transcriptional responses, cytotoxicity, and in vivo antileukemic activity in the presence of as little as 1 nM rapamycin. Rapamycin withdrawal paused DARIC33-stimulated T cell effector functions, which were restored following reexposure to rapamycin, demonstrating reversible effector function control.

Si des études ont déjà souligné l'influence de l'épigénétique dans le développement de tumeurs, c'est la première fois qu'il est démontré que les mutations de l’ADN - qui s'accumulent au niveau du génome - ne sont pas indispensables à l'apparition des cancers. En d'autres termes, cette découverte montre que des processus pas forcément génétiques sont entièrement capables de provoquer l'apparition et le développement de tumeur, ouvrant ainsi la voie à de nouvelles pistes thérapeutiques.

Le Groupe de direction mondial sur la résistance aux antimicrobiens – antibiotiques notamment – appelle les Etats membres de l’ONU à réagir urgemment face à cette menace croissante. Sa dernière étude laisse envisager un coût humain et économique vertigineux si des mesures fortes ne sont pas rapidement prises contre la résistance aux antimicrobiens.

Fewer than 50% of patients who are treated with CAR T therapies remain cured after one year. One of the reasons for this is that CAR T cells often don’t survive long enough in patients to completely eradicate their cancer. However, other studies showed that patients who were cured by CAR T therapy had cells that were more durable and able to fight the cancer longer. Results from the Nature study indicate that longer lasting cells benefit from a protein called FOXO1, which improves the survival and function of CAR T cells.

Why haven’t CAR-T therapies cracked into solid tumors yet? Poseida Therapeutics is trying to fill in at least one piece of the puzzle with a new analysis presented at the American Association for Cancer Research annual meeting showing that patients may need a higher dose of lymphodepletion than those with blood cancers.

In June, the FDA released a warning about the new antiobesity medications, stating it had received reports of adverse events after people self-administered semaglutide from a compounding pharmacy. The warning also states that compounding pharmacies may be selling salt forms of the active ingredient, including semaglutide sodium and semaglutide acetate, though the FDA is not aware of any basis for compounding a drug using semaglutide salts that would meet federal requirements.

The trial, which will take place at Kyoto University Hospital from September to August 2025, will treat 30 males aged 30-64 who are missing at least one molar. The intravenous treatment will be tested for its efficacy on human dentition, after it successfully grew new teeth in ferret and mouse models with no significant side effects.

CAR-T cell therapies have boomed in the past few years since the first FDA approval of this revolutionary new way of treating blood cancer back in 2017, but, while the technology has sped through, cancer doctors are feeling a little left behind. That’s according to a new survey and report from IQVIA, timed to come out alongside this year’s American Society of Clinical Oncology (ASCO) cancer congress abstracts drop, which asked 100 CAR-T oncologists about how well they felt informed about cell therapies.

The eight constituents of TwX include vitamin C, L-glutamine, niacin, L-cystine, coenzyme Q10, vitamin B2, succinic acid, and fumaric acid. The combined antioxidant effect is likely more potent than the activity of either compound alone. Previous studies have demonstrated improvement in cognition, memory, and motor coordination in mouse models of dementia, and reduction in affected region size, oxidative stress, and inflammation in mouse models of ischemic stroke following treatment with TwX.

At a joint event held by the Friends of Cancer Research and Parker Institute for Cancer Immunotherapy on Monday, cell therapy pioneer Carl June of the University of Pennsylvania Perelman School of Medicine revealed findings from a recent unpublished study from his group that looked at 783 patients who had received CAR-T treatments for HIV-1 or various cancers. Over more than 2,200 patient-years of observation, the group found 18 patients, or 2.3%, who developed secondary malignancies.

Instead of waiting anywhere from 30 minutes to several hours for infusions into their veins, patients would spend just a few minutes being injected under the loose skin of their abdomens or thighs. Clinicians would save time and money, and patients would leave the clinic much sooner than normal. The ease of subcutaneous injections also opens up an opportunity for home treatment, a potential boon for people who don't want to spend their remaining time on hospital visits.

CAR T-cell therapy is a type of cancer treatment that genetically modifies your own immune T-cells to recognize and fight cancer. This treatment has been successful in some blood cancers but is less effective in solid cancers for several reasons, including poor cell persistence and functionality in a hostile tumor environment. The latest research, using ovarian, breast and colon cancer models, has identified a gene that can be stimulated to make the cells younger, fitter, more dynamic and effective in fighting solid tumors.
