Retatrutide is an investigational synthetic peptide that acts as an agonist at three distinct G protein-coupled receptors. It combines activity at the glucagon-like peptide-1 receptor, the glucose-dependent insulinotropic polypeptide receptor, and the glucagon receptor within a single molecule. This multi-receptor profile distinguishes it from earlier incretin-based compounds that engage one or two of these pathways. Researchers designed the molecule to test whether simultaneous activation produces greater metabolic effects than single or dual agonism alone.
The peptide backbone is chemically modified to resist rapid enzymatic breakdown in the body. A fatty acid side chain promotes binding to serum albumin, which slows renal clearance and supports an extended circulation time. These modifications allow less frequent administration than would be possible with an unmodified peptide. The precise contribution of glucagon receptor activation to the overall metabolic effect remains an area of active investigation, because glucagon raises glucose while also increasing energy expenditure.
Trial reports for this compound rely on a small set of repeated measures. Body weight is normally expressed as percent change from baseline at a fixed week, with absolute kilograms given secondarily. Glycemic endpoints include HbA1c, fasting glucose, and, in some protocols, continuous glucose monitoring summaries. Imaging endpoints such as MRI-derived proton density fat fraction quantify liver fat. Standardization matters because a percent change and a categorical responder analysis can tell different stories about the same dataset.
Body composition is assessed with dual-energy X-ray absorptiometry or comparable methods, which separate fat mass from lean mass. Reported losses include both compartments, and the ratio between them is a subject of ongoing analysis rather than a settled result. Waist circumference, blood pressure, and lipid panels are collected as supporting measures. Resting energy expenditure and substrate oxidation are measured in smaller mechanistic studies, where glucagon receptor activity is expected to matter. These substudies are typically short and small, so their findings carry wide uncertainty.

Retatrutide is an investigational synthetic peptide engineered to activate three distinct hormone receptors within a single molecule. It targets the glucose-dependent insulinotropic polypeptide receptor, the glucagon-like peptide-1 receptor, and the glucagon receptor simultaneously. This triagonist design distinguishes it from earlier incretin-based compounds that act on one or two of these pathways. Structural modifications relative to native gut hormones extend its residence time in circulation. The molecule remains under clinical evaluation and is not approved for any indication.
Receptor activation produces downstream effects that differ by tissue. GLP-1 receptor signaling influences appetite regulation and insulin secretion in a glucose-dependent manner. GIP receptor activity contributes to metabolic handling of nutrients and may modulate adipose tissue. Glucagon receptor engagement raises energy expenditure and promotes hepatic lipid turnover, though the balance among these actions in humans is still being characterized. Preclinical models showed reductions in body weight and improved glycemic markers.

== Cause == A cystocele occurs when the muscles, fascia, tendons and connective tissues between a woman's bladder and vagina weaken, or detach. The type of cystocele that can develop can be due to one, two or three vaginal wall attachment failures: the midline defect, the paravaginal defect, and the transverse defect. The midline defect is a cystocele caused by the overstretching of the vaginal wall; the paravaginal defect is the separation of the vaginal connective tissue at the arcus tendineus fascia pelvis; the transverse defect is when the pubocervical fascia becomes detached from the top (apex) of the vagina. There is some pelvic prolapse in 40–60% of women who have given birth. Muscle injuries have been identified in women with cystocele. These injuries are more likely to occur in women who have given birth than those who have not. These muscular injuries result in less support to the anterior vaginal wall. Some women with connective tissue disorders are predisposed to developing anterior vaginal wall collapse. Up to one third of women with Marfan syndrome have a history of vaginal wall collapse. Ehlers-Danlos syndrome in women is associated with a rate of 3 out of 4.
== Symptoms and signs == In the event more ATP is needed from the affected pathway, the lack of it becomes an issue and symptoms develop. People with a metabolic myopathy often experience symptoms such as:
The flag of Zimbabwe Rhodesia was designed by Flight Lieutenant Cedric Herbert of the Rhodesian Air Force and a member of the Rhodesian Heraldry and Genealogy Society. The design incorporated the pan-African colours of yellow, black, green and red, with the soapstone bird of Great Zimbabwe, representing an older, pre-colonial source of power and identity in yellow on a vertical black stripe, symbolising the importance of majority rule, and three horizontal stripes, one red representing the blood spilled in the struggle for majority rule, one white, representing the integral part of the European community and other minorities in all aspects of the country's life, and one green, reflecting the importance of agriculture to the country's well-being. The new design had little support from black politicians, who described it as "the flag with two names", a reference to Zimbabwe Rhodesia. The Voice of Zimbabwe radio service operated by Robert Mugabe's ZANU–PF from Maputo in Mozambique carried a commentary entitled "The proof of independence is not flags or names", dismissing the changes as aimed at "strengthening the racist puppet alliance's position at the Zimbabwe conference in London". This flag was officially superseded in December 1979 when Britain took interim control of the country following the Lancaster House Agreement which ended the Rhodesian Bush War. The Union Jack was used as the official flag of the country, although de facto the Zimbabwe Rhodesia flag continued to be flown, while fresh elections were held in February 1980.

=== Form === Military grade C-4 is commonly packaged as the M112 demolition block. The demolition charge M112 is a rectangular block of Composition C-4 about 2 by 1.5 inches (51 mm × 38 mm) and 11 inches (280 mm) long, weighing 1.25 lb (570 g). The M112 is wrapped in a sometimes olive color Mylar-film container with a pressure-sensitive adhesive tape on one surface. The M112 demolition blocks of C-4 are commonly manufactured into the M183 "demolition charge assembly", which consists of 16 M112 block demolition charges and four priming assemblies packaged inside military Carrying Case M85. The M183 is used to breach obstacles or demolish large structures where larger satchel charges are required. Each priming assembly includes a five-or-twenty-foot (1.5 or 6.1 m) length of detonating cord assembled with detonating cord clips and capped at each end with a booster. When the charge is detonated, the explosive is converted into compressed gas. The gas exerts pressure in the form of a shock wave, which demolishes the target by cutting, breaching, or cratering. Other forms include the mine-clearing line charge and M18A1 Claymore mine.
=== Progestogenic activity === CPA is a highly potent progestogen. It is described as the most potent progestin of the 17α-hydroxyprogesterone group, being about 1,200-fold more potent than hydroxyprogesterone acetate, 12-fold more potent than medroxyprogesterone acetate, and 3-fold more potent than chlormadinone acetate in animal bioassays. Based on results in the animal bioassays, CPA has also been said to be the most potent progestin known, with 1,000 times the potency of progesterone. With oral administration in humans however, CPA is distinctly less potent as a progestogen than various other progestins such as the 19-nortestosterone derivatives. The effective dosage of CPA needed to inhibit ovulation by itself in women (i.e., to act as a contraceptive) is 1 mg/day, and the medication is marketed as a contraceptive (combined with low-dose ethinylestradiol) at a dosage of 2 mg/day. For comparison, the ovulation-inhibiting dosage of levonorgestrel is 50 μg/day. At the dosages typically used clinically, CPA is described as a "strong" and "powerful" progestogen. Its endometrial transformation dosage is 20 to 30 mg per cycle and its menstrual delay test dosage has been estimated to be less than 1 mg/day. CPA is not well-balanced in terms of its activities; relative to the progestogenic potency of CPA, its potency as an androgen receptor antagonist is quite weak. In order to take full advantage of its antiandrogenic activity, CPA must be administered at a dosage of 50 to 100 mg per day, which is 2 to 3 times the cyclical endometrial transformation dose per day.
=== Revita === Revita is an outpatient endoscopic procedure that resurfaces the mucosal lining of the duodenum using ablation with water and heat. The duodenal lining can thicken with chronic high-fat and high-sugar diets; this can damage signaling mechanisms in the gastrointestinal tract and lead to metabolic disease. After resurfacing, a healthy mucosal layer can regrow over time, potentially improving blood sugar regulation and insulin sensitivity.

=== Gait === The hunched position that often results from complete spinal fusion can have an effect on a person's gait. Increased spinal kyphosis will lead to a forward and downward shift in center of mass (COM). This shift in COM has been shown to be compensated by increased knee flexion and ankle dorsiflexion. The gait of someone with ankylosing spondylitis often has a cautious pattern because they have decreased ability to absorb shock, and they cannot see the horizon.
an optimized medium (for Chlamydomonas reinhardtii), an examination of the nutritional conditions including higher salinity and nitrogen concentration (for Botryococcus braunii), the addition of sulfate and magnesium salts in the culture medium (P. cruentum), a co-culturing of Chlorella and Spirulina with the Basidiomycete Trametes versicolor, and a novel mutagenesis tool (atmospheric and room temperature plasma, ARTP), leading to an increase of EPS production of up to 34% (volumetric yield of 1.02 g/L). It was suggested that co-cultures of microalgae and other microorganisms can be used more universally as a technology to increase the production of EPS, since microorganisms may respond to the interaction partners by secreting EPS as a strategy during unfavorable conditions.

Retatrutide is an investigational synthetic peptide that activates three metabolic receptors: GLP-1, GIP, and glucagon. It is being studied for obesity and type 2 diabetes. It has not been approved for clinical use.
Earlier incretin therapies engage one or two receptors. Retatrutide adds glucagon receptor activity, which may raise energy expenditure. Whether this produces larger clinical benefits is still being tested.
It has completed phase 2 trials and moved into later-stage evaluation. No regulator has granted approval. Access outside research settings is not authorized.
A responder analysis counts participants who cross a threshold, such as five or ten percent weight loss. It complements average percent change by showing how widely results are distributed. The two measures can diverge when a subset of participants loses a large amount.
