This page was last updated on 2025-10-15 and is reviewed periodically as new material appears.
In laboratory settings, cardarine is studied as a tool compound for probing PPARδ biology. Published experiments often use cell cultures, rodent models, or isolated tissues. Some investigations focus on metabolic effects, while others assess potential risks such as carcinogenicity observed in long-term animal studies. Because human trials are sparse, most knowledge comes from preclinical work and adverse event reports. Scientific literature frequently notes the gap between animal findings and human outcomes. The compound is not a dietary supplement and is not intended for human consumption.
Cardarine is a common name for GW501516, a synthetic compound developed in the 1990s through research collaborations involving GlaxoSmithKline. It belongs to a class of molecules known as peroxisome proliferator-activated receptor delta agonists. Early studies explored its effects on lipid metabolism and energy expenditure in animal models. The compound was never approved as a human medicine, and clinical development was discontinued. In the years since, it has appeared in fitness and bodybuilding communities as a performance-enhancing substance. Regulatory agencies classify it as an unapproved drug.
Published literature on cardarine includes in vitro assays, rodent experiments, and a small number of human studies. Reports describe effects on exercise capacity and lipid metabolism in animals, while human evidence is sparse. Many online descriptions present the compound as a proven endurance aid, a claim not supported by regulatory approval or large clinical trials. Analytical studies focus on identifying the parent compound and its metabolites in biological samples. Important uncertainties include species differences, dose-response relationships, and the relevance of rodent tumor findings to humans.

PPARδ is a nuclear receptor that influences transcription of genes involved in fatty acid oxidation, lipid transport, and energy homeostasis. GW501516 binds and activates this receptor with high selectivity relative to PPARα and PPARγ in laboratory assays. Activation alters expression of target genes in skeletal muscle, liver, and adipose tissue in animal models. The exact clinical consequences of these changes in humans remain incompletely characterized, and observed effects in animals do not establish therapeutic benefit or safety.
Published studies have examined GW501516 in animal models of obesity, insulin resistance, and exercise endurance. Early human trials reportedly ended, and development was discontinued after preclinical findings raised concerns about cancer in some rodent studies. Regulatory agencies have not approved cardarine for any medical use. Its availability through non-pharmaceutical channels raises questions about identity, purity, and legal status that are separate from its laboratory pharmacology. Those questions are often addressed through analytical testing rather than assumptions about product labels.
Cardarine is a common name for GW501516, also GW-1516, a synthetic compound developed as a peroxisome proliferator-activated receptor delta (PPARδ) agonist. It belongs to a class of agents that modulate gene transcription related to lipid and energy metabolism. The compound was studied in preclinical and early clinical research for metabolic and cardiovascular conditions, but it did not progress to approved therapeutic use. Its name appears in fitness and sports contexts despite not being approved as a drug.
Clinical development stopped after rodent studies showed tumors at multiple sites. Whether those findings predict human cancer risk remains an open question, but they led sponsors to discontinue programs. Human safety data are limited to small, short-term studies that were not designed to assess cancer risk. Reported effects in those studies included changes in blood lipids, but the evidence is insufficient for medical use. Long-term consequences of nonmedical use are not well characterized. Questions about dose, duration, and individual susceptibility remain unresolved.
Cardarine is a common name for GW501516, an investigational compound developed in the 1990s for metabolic conditions. It acts as an agonist at peroxisome proliferator-activated receptor delta, a nuclear receptor involved in lipid and energy metabolism. The compound is frequently mislabeled as a selective androgen receptor modulator, or SARM, but its molecular target is different. GW501516 reached early clinical testing before development was discontinued. It has no approved therapeutic use in any country. The name cardarine is not a formal international nonproprietary name.
Newborn screening (NBS) is a public health program of screening in infants shortly after birth for conditions that are treatable, but not clinically evident in the newborn period. The goal is to identify infants at risk for these conditions early enough to confirm the diagnosis and provide intervention that will alter the clinical course of the disease and prevent or ameliorate the clinical manifestations. NBS started with the discovery that the amino acid disorder phenylketonuria (PKU) could be treated by dietary adjustment, and that early intervention was required for the best outcome. Infants with PKU appear normal at birth, but are unable to metabolize the essential amino acid phenylalanine, resulting in irreversible intellectual disability. In the 1960s, Robert Guthrie developed a simple method using a bacterial inhibition assay that could detect high levels of phenylalanine in blood shortly after a baby was born. Guthrie also pioneered the collection of blood on filter paper which could be easily transported, recognizing the need for a simple system if the screening was going to be done on a large scale. Newborn screening around the world is still done using similar filter paper. NBS was first introduced as a public health program in the United States in the early 1960s, and has expanded to countries around the world. Screening programs are often run by state or national governing bodies with the goal of screening all infants born in the jurisdiction for a defined panel of treatable disorders.
==== United States ==== 4-HO-DPT is not an explicitly controlled substance in the United States. However, the drug is a close analogue of psilocin (4-HO-DMT), which is a Schedule I controlled substance in this country, and hence sale for intended human consumption could be illegal under the Federal Analogue Act.
Two adults and five children at the Kindercare kindergarten in Christchurch suffer chemical burns after being accidentally exposed to a hazardous substance being poured on a waterslide. The Controller and Auditor-General of New Zealand launches an investigation into the Chatham Islands Council's expenditure and procurement policies. Craig Stobo temporarily steps down as chairperson of the Financial Market Authority pending an investigation by the Ministry of Business, Innovation and Employment (MBIE). 6 December — A measles case is reported in Queenstown, bringing the total number of cases reported nationally to 30. 22 cases are no longer infectious. 8 December: A wildfire engulfs over 320 hectares of Tongariro National Park, leading to the closure of sections of State Highway 47.

The New Zealand Government announces two proposed bills to replace the Resource Management Act 1991.
When used for analysis of mixtures, the eluant is usually collected in fractions of 1–5 ml which can be further analyzed. When used for protein purification there may be only two collection containers: one for the purified product and one for waste.
Unlike global alignment approaches, local structural alignment approaches are suited to detection of locally conserved patterns of functional groups, which often appear in binding sites and have significant involvement in ligand binding. As an example, comparing G-Losa, a local structure alignment tool, with TM-align, a global structure alignment based method. While G-Losa predicts drug-like ligands' positions in single-chain protein targets more precisely than TM-align, the overall success rate of TM-align is better. However, as algorithmic improvements and computer performance have erased purely technical deficiencies in older approaches, it has become clear that there is no one universal criterion for the 'optimal' structural alignment. TM-align, for instance, is particularly robust in quantifying comparisons between sets of proteins with great disparities in sequence lengths, but it only indirectly captures hydrogen bonding or secondary structure order conservation which might be better metrics for alignment of evolutionarily related proteins. Thus recent developments have focused on optimizing particular attributes such as speed, quantification of scores, correlation to alternative gold standards, or tolerance of imperfection in structural data or ab initio structural models. An alternative methodology that is gaining popularity is to use the consensus of various methods to ascertain proteins structural similarities.

The compound known as TCV-116 (candesartan) was studied by Japanese scientists using standard laboratory rats. Animal studies were published showing the effectiveness of the compound in 1992–1993, with a pilot study on humans published in the summer of 1993.
== Medical uses == Lercanidipine is used for the treatment of essential hypertension (high blood pressure). Lercanidipine seems to be a good agent in treating hypertensive patients who also have kidney issues.
Hemoglobin electrophoresis is a test that can detect different types of hemoglobin. Hemoglobin is extracted from the red cells, then introduced into a porous gel and subjected to an electrical field. This separates the normal and abnormal types of hemoglobin which can then be identified and quantified. Due to reduced production of HbA in beta thalassemia, the proportion of HbA2 and HbF relative to HbA are generally increased above normal. In alpha thalassemia the normal proportion is maintained. High-performance liquid chromatography (HPLC) is reliable, fully automated, and able to distinguish most types of abnormal hemoglobin including carriers, The method separates and quantifies hemoglobin fractions by measuring their rate of flow through a column of absorbent material. DNA analysis using polymerase chain reaction (PCR) or next-generation sequencing. These tests can identify carriers of thalassemia genes and combination hemoglobinopathies, as well as identifying the exact mutation which underlies the disease.
== Research == Bicalutamide has been studied in combination with the 5α-reductase inhibitors finasteride and dutasteride in prostate cancer. It has also been studied in combination with raloxifene, a selective estrogen receptor modulator (SERM), for the treatment of prostate cancer. Bicalutamide has been tested for the treatment of AR-positive ER/PR-negative locally advanced and metastatic breast cancer in women in a phase II study for this indication. Enzalutamide is also being investigated for this type of cancer. Bicalutamide has also been studied in a phase II clinical trial for ovarian cancer in women. Bicalutamide has been studied in the treatment of benign prostatic hyperplasia (BPH) in a 24-week trial of 15 patients at a dosage of 50 mg/day. Prostate volume decreased by 26% in patients taking bicalutamide and urinary irritative symptom scores significantly decreased. Conversely, peak urine flow rates and urine pressure flow examinations were not significantly different between bicalutamide and placebo. The decrease in prostate volume achieved with bicalutamide was comparable to that observed with the 5α-reductase inhibitor finasteride, which is approved for the treatment of BPH. Breast tenderness (93%), gynecomastia (54%), and sexual dysfunction (60%) were all reported as side effects of bicalutamide at the dosage used in the study, although no treatment discontinuations due to adverse effects occurred and sexual functioning was maintained in 75% of patients.

These findings extend the use of MPPT into dermatology and positive effects have been observed in hidradenitis suppurativa. The MPPT technology has been approved in the EU as a "treatment for wounds" and is currently the only wound product with this approval. Other medical devices for wounds are approved to have a certain effect on the wound, e.g. add moisture or remove wound exudate, but they are not recognised as treatments.
Mercabarna is a food-trading estate that concentrates wholesale markets (fruit and vegetables, fish and flowers) and Barcelona's abattoir, as well as a large area of complementary activities (ZAC), boasting some 450 fresh-food preparation, commercial, distribution, importing and exporting businesses. A total of 700 businesses are located within its 90-hectare site. It supplies over ten million people and is a benchmark market worldwide. Mercabarna, as public limited company, was founded in 1967 in Barcelona. In the past, wholesale food markets were situated in central locations within the city of Barcelona and occupied buildings which are now used for important social, cultural and leisure facilities. The growth of the city and of its population led to problems of all kinds for these central markets in terms of capacity, communications, the environment and so forth. Gradually, therefore, they relocated to the Mercabarna precinct. In 2019 it sold 2,355,293 tons of food, 4.2% more than in 2018. The turnover of the companies that sell there exceeds 5 billion euros. The economic crisis resulting from the COVID-19 pandemic negatively impacted the sales of some of these businesses, especially those in the hospitality and catering sector.
Belize Electricity Limited (BEL), the nation's primary distributor of electricity, proposed a $500 million investment to support the integration of 60 MW of utility-scale solar photovoltaic (PV) generation and 40 MW of battery energy storage systems in its 2024–2028 Full Tariff Review, in an effort to stabilize electricity rates at 40 cents per kilowatt-hour and reduce reliance on imported electricity from Mexico. The Government of Belize's National Energy Policy 2023–2040 commits to achieving 75% renewable energy in the electricity generation mix by 2030. As of 2022, renewable sources accounted for 53% of total gross electricity generation. To improve grid reliability, BEL has initiated several infrastructure upgrades. In 2024, the company completed an upgrade of the West Lake Gas Turbine, increasing its capacity from 19 MW to 30 MW. Additionally, a new gas turbine was installed on Ambergris Caye, adding 20 MW of generation capacity to the national grid. The World Bank is supporting these efforts through the Belize Energy Resilience and Sustainability Project, which includes the deployment of four 10 MW battery storage systems in key districts. Belize Telemedia Limited (BTL), operating under the brand Digi, is the nation's primary telecommunications provider. As of 2025, BTL maintains approximately 32,000 fixed telephone line contracts and serves around 190,000 GSM mobile customers, with active expansion ongoing in accordance with the Government of Belize's National Digital Agenda 2022–2025.
Treponema pallidum, formerly known as Spirochaeta pallida, is a microaerophilic, gram-negative, spirochaete bacterium with subspecies that cause the diseases syphilis, bejel (also known as endemic syphilis), and yaws. It is known to be transmitted only among humans and baboons. T. pallidum can enter the host through mucosal membranes or open lesions in the skin and is primarily spread through sexual contact. It is a helically coiled microorganism usually 6–15 μm long and 0.1–0.2 μm wide. T. pallidum's lack of both a tricarboxylic acid cycle and processes for oxidative phosphorylation results in minimal metabolic activity. As a chemoorganoheterotroph, Treponema pallidum is an obligate parasite that acquires its glucose carbon source from its host. Glucose can be used not only as a primary carbon source but also in glycolytic mechanisms to generate ATP needed to power the bacterium given its minimal genome. The treponemes have cytoplasmic and outer membranes. Using light microscopy, treponemes are visible only by using dark-field illumination. T. pallidum consists of three subspecies, T. p. pallidum, T. p. endemicum, and T. p. pertenue, each of which has a distinct related disorder. The ability of T. pallidum to avoid host immune defenses has allowed for stealth pathogenicity. The unique outer membrane structure and minimal expression of surface proteins of T. pallidum has made vaccine development difficult. Treponema pallidum can be treated with high efficacy by antibiotics that inhibit bacterial cell wall synthesis such as the beta-lactam antimicrobial penicillin-G.
Where M is the analyte molecule, X+ is the cation and A is a non-reacting collision partner. In a radioactive ion source, a small piece of radioactive material, for instance 63Ni or 241Am, is used to ionize a gas. This is used in ionization smoke detectors and ion mobility spectrometers.

Cardarine is a common name for GW501516, a synthetic PPARδ agonist developed for research. It has not been approved as a medication in any country. It is classified as an unapproved drug and a prohibited substance in sport.
No. Cardarine is not an anabolic steroid; it belongs to a different chemical class that targets PPARδ. Steroids act primarily through androgen receptors, while cardarine acts through a nuclear receptor involved in metabolism.
Some rodent studies reported increased endurance and changes in fat metabolism after cardarine exposure. Long-term studies in animals also raised concerns about cancer in certain tissues. Human trial data are limited, so these findings cannot be directly translated to people.
