···

Oprava chyby Garmin Connect pro iOS je venku poté, co hodinky přestaly synchronizovat — ale ne všichni jsou zpět online

Garmin released Garmin Connect 5.21.1 for iOS to fix watch sync issues after recent updates. Some users must unpair and re-pair devices, which deletes Garmin Pay data. The bug affects Fenix 8, Venu 4, and Forerunner 970 paired with iPhones, not Android. Reports show the fix does not work for everyone; some watches remain unrecognized.

Prasečí neurony v lidském mozku? Realita roku 2025 v xenotransplantaci neuronů—průlomy, rizika a co nás čeká dál

The FDA approved the first clinical trials of kidney xenotransplantation in 2024. Preclinical studies show pig neuron precursors can function in rodents and marine mammals, while human neurons integrate in animal brains for research. No neuron xenotransplants have been performed in patients. Advances in gene editing and immune protection have improved safety for all xenotransplantation.

Tajní zabijáci „zombie buněk“: Speciální senolytické léky bojující proti stárnutí

A phase 2 Mayo Clinic trial published July 2024 found dasatinib and quercetin modestly increased wrist bone density in women over 65 with high senescent cell burden. Unity Biotechnology’s foselutoclax improved vision in diabetic macular edema patients in phase 2. About 20 senolytic drug trials were ongoing worldwide as of 2024–2025. Results for Alzheimer’s disease studies are expected in 2025.

Otočení času zpět: Jak Yamanakovy faktory resetují stárnoucí buňky

Cyklické podávání faktorů OSKM prodloužilo život myší s progerií o 33 % a u starých myší zvýšilo zbývající délku života přibližně dvojnásobně. U zdravých myší vedlo k omlazení tkání bez známek rakoviny. Terapie OSK obnovila zrak makakům a snížila epigenetický věk lidských buněk o desítky let. Firmy Turn Bio a Altos Labs investují do vývoje terapií, přetrvávají však obavy z bezpečnosti.

Biotechnologie 2025: Průlomové léky, superplodiny a revoluce zelených technologií

The global biotechnology market is projected to grow from $483 billion in 2024 to $546 billion in 2025, a 13% increase. Casgevy gene therapy for sickle cell disease and beta-thalassemia is expected to reach patients in 2025. Novo Nordisk and Eli Lilly are investing billions to address U.S. shortages of GLP-1 drugs. Over 60% of new crop varieties in 2025 use CRISPR technology.

Za hranice vakcín proti COVID-19: mRNA revoluce měnící medicínu

Over 13 billion mRNA COVID-19 vaccine doses were delivered globally by end-2022, showing 94–95% efficacy. Moderna’s mRNA RSV vaccine for adults 60+ received FDA approval in May 2024 after phase 3 trials showed 83.7% efficacy. Katalin Karikó and Drew Weissman won the 2023 Nobel Prize for mRNA technology. FDA fast-tracked Moderna’s mRNA therapy for MMA in June 2024.

Konec laboratorních krys: Jak technologie orgánů na čipu revolucionalizuje testování léků

In 2022, scientists connected four human tissues—heart, liver, bone, and skin—on a single chip with circulating fluid and immune cells, keeping them alive for weeks. The FDA announced plans in April 2025 to phase out many animal tests within 3–5 years. A kidney-on-a-chip identified 87% of drugs toxic to human kidneys. In 2024, Argenx submitted liver-on-a-chip data to the FDA as part of an IND application.

Revoluce genové terapie: léčby, průlomy a výzvy v genetické medicíně

FDA approved Casgevy in December 2023 as the first CRISPR-based therapy for sickle cell disease and beta-thalassemia. In early 2025, CHOP doctors treated an infant with in vivo CRISPR base editing for CPS1 mutation, reported in NEJM. In 2025, in vivo ANGPTL3 editing cut triglycerides by 82% and LDL by 65% in one patient. Luxturna, Zolgensma, Hemgenix, Roctavian, Strimvelis, Libmeldy, and several CAR-T therapies have also received FDA approval since 2016.
