How this library is organized

Studies default to publication date, newest first, not the date a summary was added. Choose Most relevant for human-first editorial reading order, not an effectiveness or quality ranking. Design, topic and intervention-candidate labels assist discovery; they are not formal appraisals. Result-direction and sample-size filters only use existing verified metadata; missing values are excluded when those filters are active. Study counts are publications, not unique trials or participants.

Human · Controlled study · 2026-10-27

Non-steady-state modelling reveals reduced skeletal muscle protein synthesis as the primary driver of disuse-atrophy in young, healthy females.

A controlled mechanistic study examined whether muscle disuse reduces synthesis or increases breakdown, accounting for shrinking muscle-protein pools.

Population, studied exposure & key finding
Population
Fourteen healthy young women, average age 21.
Studied dose & duration
One leg underwent 10 days of unloading; the opposite leg performed resistance exercise. Deuterated water, MRI and mathematical models assessed turnover and muscle size.
Finding
Unloading reduced muscle volume and mixed/myofibrillar protein synthesis. Model-derived breakdown did not increase. Accounting for the shrinking protein pool preserved this conclusion. Integrated synthesis in the exercised leg did not rise above baseline.

Efficacy and Safety of Lonapegsomatropin in Children With Turner Syndrome: 52-Week Results From the New InsiGHTS Trial.

A randomized phase 2 trial compared weekly lonapegsomatropin with daily somatropin for growth in Turner syndrome.

Population, studied exposure & key finding
Population
49 prepubertal children were enrolled and dosed, according to the publication.
Studied dose & duration
Weekly subcutaneous lonapegsomatropin starting doses: 0.24, 0.30 or 0.36 mg hGH/kg/week. Daily somatropin totaled 0.35 mg/kg/week, not per day; 52 weeks.
Finding
Primary week-26 annualized height velocity was 9.23–10.36 cm/year across weekly starting-dose groups versus 10.86 with daily treatment. Secondary week-52 rates were 9.05 pooled versus 9.04 cm/year. The abstract reported similar tolerability.

Single Intranasal Administration of the Psychedelic Mebufotenin for Treatment-Resistant Depression: A Randomized Clinical Trial.

A phase 2b randomized trial tested intranasal mebufotenin benzoate for treatment-resistant depression.

Population, studied exposure & key finding
Population
193 adults with moderate-to-severe depression after inadequate response to prior antidepressant treatments.
Studied dose & duration
One intranasal dose: 8 mg, 12 mg or 0.3 mg low-dose comparator, with psychological support and antidepressant washout as needed; eight-week follow-up.
Finding
Primary day-29 depression-score difference for 12 versus 0.3 mg: −5.3 MADRS points (95% CI −8.9 to −1.8). Adverse events affected 85% versus 73%; most events across groups were mild or moderate.

Corn protein alone, or in blends, stimulates muscle protein synthesis comparable to milk protein, with or without resistance exercise, in older adults.

A randomized acute-feeding trial compared corn, pea/corn and milk proteins for muscle protein synthesis.

Population, studied exposure & key finding
Population
48 healthy older adults, average age 68; equal numbers of men and women.
Studied dose & duration
One oral 20 g protein serving versus low-energy nonprotein placebo. Participants exercised one leg; the other provided a resting comparison.
Finding
Protein-synthesis increases from baseline were 216 percent with corn, 217 percent with pea/corn, 138 percent with milk and 77 percent with placebo. Protein groups exceeded placebo; no active-protein difference was detected. Exercise further increased synthesis.

Creatine supplementation effects on cognition, sleep, and menopause symptoms in response to six weeks of high-intensity resistance training in perimenopausal females.

An exploratory randomized study tested creatine with resistance training for cognition, sleep and perimenopause symptoms.

Population, studied exposure & key finding
Population
51 perimenopausal women, average age 46, assigned to creatine, placebo or a nontraining control.
Studied dose & duration
Oral creatine monohydrate 20 g/day for 5 days, then approximately 4.5 g/day for six weeks; creatine and placebo groups trained twice weekly.
Finding
Sleep consistency at week 6 favored creatine by 7.4 percentage points versus placebo after baseline adjustment (p=0.015). Prefrontal oxygenation increased, but Stroop reaction-time improvement did not differ between groups.

Semaglutide modulates explore/exploit decision-making in major depressive disorder: A randomized clinical trial.

A secondary trial analysis examined semaglutide effects on modeled decision strategies, not general intelligence.

Population, studied exposure & key finding
Population
72 adults with major depression, overweight/obesity and cognitive difficulties; semaglutide versus placebo.
Studied dose & duration
Oral semaglutide titrated from 3 to 14 mg over eight weeks, versus placebo alongside usual treatment; 16-week study.
Finding
The model suggested more use of known high-reward choices, exploration of uncertain options and choice repetition. However, adjusted task-performance comparisons were not significant, and the parent trial found no executive-function benefit.

Retatrutide Once Weekly for Treatment of Obstructive Sleep Apnea.

Two randomized OSA subtrials tested retatrutide versus placebo, nested within larger phase 3 trials.

Population, studied exposure & key finding
Population
Adults with overweight/obesity and moderate-to-severe sleep apnea: 243 without and 448 with type 2 diabetes.
Studied dose & duration
Subcutaneous retatrutide 4, 9 or 12 mg once weekly versus placebo for 80 weeks; doses describe the study.
Finding
At 9 mg, placebo-adjusted AHI differences were −24.4 events/hour (95% CI −34.1 to −14.7) without diabetes and −14.4 (−21.6 to −7.2) with diabetes, using the hybrid estimand. Corresponding intention-to-treat differences were −24.7 and −13.9. Gastrointestinal events were most common.

Cardiovascular effects of continued vs. discontinued anabolic-androgenic steroid use: a longitudinal follow-up study.

A longitudinal cohort examined cardiac changes after continued or discontinued steroid use.

Population, studied exposure & key finding
Population
70 men with steroid-use histories and 35 nonusing weightlifters returned for follow-up.
Studied dose & duration
Self-selected steroid use, cessation or continued abstinence; no standardized treatment regimen.
Finding
Continued users had ejection fraction 48 percent and indexed ventricular mass 119 g/m². Those stopping showed a six-percentage-point ejection-fraction improvement and 21 g/m² mass-index reduction.

Finding
Bench repetitions were 56.0 with nitrate versus 58.9 with placebo; leg-press repetitions were 79.3 versus 80.4. Differences were not significant. Exertion, heart rate, blood pressure and lactate also did not improve.
