We need to translate Russian news post into English, format per rules.
First line: short headline under 90 chars, no markdown. Then blank line, then body split into short paragraphs (2-3 sentences each), separated by blank lines.
Wrap few genuinely important facts — key numbers, percentages, drug/company/gene names, dates — in double asterisks . At most 4-5 per post, never a whole sentence.
Wrap study/journal citations and publication references in single underscores _ (e.g., Nature Aging, July 2026).
We need to preserve all facts, numbers, names, citations exactly. No commentary.
We need to identify important facts: numbers like 10 August (date), 26-year-old woman, 50 microliters, 24 hour interval, 4 weeks observation, 71 days prior measurements, 45 measurements, 13 of 52 measurements after injections, left eye response day 2 to day 11, right eye day 4 to day 39, etc. Also mention mitochondria injection, vitreous body, ganglion cell layer thinning, etc.
We need to limit double asterisks to at most 4-5 per post. So we need to select maybe 4-5 key facts: date of preprint (10 August), age (26-year-old woman), volume injected (50 microliters), number of measurements after injections achieving normal threshold (13 of 52), duration of response in left eye (day 2-11) and right eye (day 4-39) maybe counts as two facts but that might exceed. We need to be selective: maybe choose date, age, volume, measurement outcome (13/52), and maybe the interval (24 hours). That's 5.
We must not wrap whole sentences; only wrap the specific fact inside double asterisks, not the whole sentence.
We need to wrap study/journal citations in single underscores. There's a preprint published 10 August; we can treat that as a citation? It says "В препринте, опубликованном 10 августа , описали две процедуры". So we can wrap the date in double asterisks? Actually date is a key number; we could wrap "10 August" in double asterisks. The preprint itself is not a journal citation; it's a preprint. The instruction: wrap study/journal citations and publication references in single underscores. So we could put the preprint reference as preprint, 10 August? But we need to keep the fact exactly. The original says "В препринте, опубликованном 10 августа". We could translate as "In a preprint published on 10 August". The date is double asterisks. The preprint itself maybe we could wrap in single underscores: preprint? But we need to preserve the fact exactly; we can't add extra words like "preprint" if not originally? It says "В препринте, опубликованном 10 августа". So we can say "In a preprint published on 10 August". The phrase "preprint" is not a citation; it's just a description. The instruction: wrap study/journal citations and publication references in single underscores. Since it's a preprint, not a journal, maybe we don't need underscores. But we could still wrap "preprint" in single underscores if we want to mark it as a publication reference. However, the instruction says to wrap study/journal citations and publication references in single underscores. So we could treat the preprint as a publication reference and wrap it: preprint published on 10 August. That would satisfy both: the reference is underscored, the date is double asterisks.
We need to ensure we don't overdo underscores; only for citations. We'll have one underscore pair.
Now body: short paragraphs 2-3 sentences each.
Let's craft translation.
Paragraph 1: Doctors injected the patient's own mitochondria into her eyes to treat severe vision loss. In a preprint published on preprint 10 August, they described two procedures: fresh mitochondria were isolated from a muscle biopsy of the 26‑year‑old woman and 50 µL were injected into the vitreous of each eye, with a 24‑hour interval between eyes.…

Patient’s own mitochondria injected into eyes in attempt to restore vision
Nature - Injection of a person’s own mitochondria into the retina was safe but had only a temporary effect on restoring vision.
