Early clinical research explored GW501516 for lipid disorders, obesity, and diabetes. Some short-term human studies reported changes in HDL cholesterol, LDL cholesterol, and triglycerides. The development program was discontinued after rodent studies showed dose-dependent tumor formation in multiple tissues, including liver, bladder, stomach, and skin. These findings raised concerns about long-term cancer risk in humans. Because human exposure data are limited, the clinical significance of the rodent tumors remains uncertain.
Literature on cardarine often separates receptor pharmacology from toxicology. Mechanistic papers describe PPARδ activation and gene expression changes, while safety assessments focus on carcinogenicity and species differences. Questions remain about whether rodent tumors arise through PPARδ-dependent or off-target mechanisms. Another open area is how human metabolism and exposure compare with those in animal studies. Analytical methods such as liquid chromatography–mass spectrometry are used to confirm identity in biological and product samples.
GW501516 acts as an agonist at the peroxisome proliferator-activated receptor delta, a nuclear receptor that regulates gene expression. Activation shifts transcription toward genes involved in fatty acid uptake, oxidation, and energy expenditure. The compound does not bind the androgen receptor and therefore differs from anabolic steroids and SARMs. In rodent models, this metabolic shift has been linked to increased running endurance and reduced fat accumulation. The exact downstream pathways in humans remain incompletely characterized.
Human trials of GW501516 were small and short in duration. They examined lipid levels, glucose handling, and other metabolic markers, but the programs were halted after the animal cancer findings. No approved therapeutic product exists, and published human data are insufficient for establishing long-term safety. Reports of use for athletic performance come mainly from non-clinical settings and cannot be verified through controlled trials. Independent testing of products sold as cardarine has found inconsistent purity and labeling.
Laboratory studies indicate that GW501516 activates PPARδ, a nuclear receptor involved in fatty acid oxidation and energy metabolism. In rodent experiments, treated animals often showed increased endurance and reduced fat mass. These effects were observed under controlled conditions and do not establish safe or effective use in humans. The exact dose-response relationship in humans remains poorly characterized. Species differences in metabolism can affect how results translate across animals and people.
Safety concerns emerged from long-term animal studies. In rodents given the compound for extended periods, researchers found an increased incidence of certain cancers, including liver and bladder tumors. These findings contributed to the discontinuation of clinical development. Whether similar risks apply to short-term or low-level exposure in humans is not established, and controlled human safety data are limited. The relevance of high-dose rodent carcinogenicity findings to human use remains a subject of debate.

Mast cells play a key role in the inflammatory process. Histamine dilates post-capillary venules, activates the endothelium, and increases blood vessel permeability. This leads to local edema (swelling), warmth, redness, and the attraction of other inflammatory cells to the site of release. It also depolarizes nerve endings (leading to itching or pain). Cutaneous signs of histamine release are the "flare and wheal" reaction. The bump and redness immediately following a mosquito bite are a good example of this reaction, which occurs seconds after challenge of the mast cell by an allergen.
=== Tolerance and dependence === Dependence typified by a withdrawal syndrome occurs in about one-third of individuals who are treated for longer than four weeks with a benzodiazepine. Higher doses and longer periods of use increase the risk of developing a benzodiazepine dependence. Potent benzodiazepines with a relatively short half-life, such as lorazepam, alprazolam, and triazolam, have the highest risk of causing dependence. If regular treatment is continued for longer than four to six months, dose increases may be necessary to maintain effects, but treatment-resistant symptoms may be benzodiazepine withdrawal symptoms. Due to the development of tolerance to the anticonvulsant effects, benzodiazepines are generally not recommended for long-term use for the management of epilepsy. Increasing the dose may overcome tolerance, but tolerance may then develop to the higher dose and adverse effects may persist and worsen. The mechanism of tolerance to benzodiazepines is complex and involves GABAA receptor downregulation, alterations to subunit configuration of GABAA receptors, uncoupling, and internalization of the benzodiazepine binding site from the GABAA receptor complex as well as changes in gene expression. Coming off long-term lorazepam use may be more realistically achieved by a gradual switch to an equivalent dose of diazepam and a period of stabilization on this, and only then initiating dose reductions.
There are different short-term and long-term effects that can arise from mutations. Smaller ones would be a halting of the cell cycle at numerous points. This means that a codon coding for the amino acid glycine may be changed to a stop codon, causing the proteins that should have been produced to be deformed and unable to complete their intended tasks. Because the mutations can affect the DNA and thus the chromatin, it can prohibit mitosis from occurring due to the lack of a complete chromosome. Problems can also arise during the processes of transcription and replication of DNA. These all prohibit the cell from reproduction and thus lead to the death of the cell. Long-term effects can be a permanent changing of a chromosome, which can lead to a mutation. These mutations can be either beneficial or detrimental. Cancer is an example of how they can be detrimental. Other effects of point mutations, or single nucleotide polymorphisms in DNA, depend on the location of the mutation within the gene. For example, if the mutation occurs in the region of the gene responsible for coding, the amino acid sequence of the encoded protein may be altered, causing a change in the function, protein localization, stability of the protein or protein complex. Many methods have been proposed to predict the effects of missense mutations on proteins.
On 27 October 1977, a group of insurgents attacked a SADF patrol in the Cutline, killing 5 South African soldiers and mortally wounding a sixth. As military historian Willem Steenkamp records, "while not a large clash by World War II or Vietnam standards, it was a milestone in what was then...a low intensity conflict". Three months later, insurgents fired on patrols in the Cutline again, killing six more soldiers. The growing number of ambushes and infiltrations were timed to coincide with assassination attempts on prominent South West African tribal officials. Perhaps the most high-profile assassination of a tribal leader during this time was that of Herero chief Clemens Kapuuo, which South Africa blamed on PLAN. Vorster finally acquiesced to Botha's requests for retaliatory strikes against PLAN in Angola, and the SADF launched Operation Reindeer in May 1978. One controversial development of Operation Reindeer helped sour the international community on the South African Border War. On 4 May 1978, a battalion-sized task force of the 44 Parachute Brigade conducted a sweep through the Angolan mining town of Cassinga, searching for what it believed was a PLAN administrative centre.

=== January 2004 === January 3: Marwan Hassoun and his cousin Zaydun Al-Samarrai are taken from their broken-down truck at about curfew time and forced to jump from the Tharthar dam into the Tigris River; the latter drowns. First Lt. Jack M. Saville and Sgt. 1st Class Tracy E. Perkins were charged on 2004 June 7 with manslaughter, assault, conspiracy, making false statements, and obstruction of justice. Sgt. Reggie Martinez was charged three weeks later with manslaughter and for making false statements, and Spec. Terry Bowman with assault and making false statements. Martinez' and Bowman's charges were dropped; Perkins got six months in jail. Saville was jailed (45 days) and fined $12,000 for assault but he remained on active duty until his military obligation was fulfilled.
Aquatic plants, also referred to as hydrophytes, are vascular plants and non-vascular plants that have adapted to live in aquatic environments (saltwater or freshwater). In lakes, rivers and wetlands, aquatic vegetations provide cover for aquatic animals such as fish, amphibians and aquatic insects, create substrate for benthic invertebrates, produce oxygen via photosynthesis, and serve as food for some herbivorous wildlife. Familiar examples of aquatic plants include waterlily, lotus, duckweeds, mosquito fern, floating heart, water milfoils, mare's tail, water lettuce, and water hyacinth. Aquatic plants require special adaptations for prolonged inundation in water, and for floating at the water surface. The most common adaptation is the presence of lightweight internal packing cells, aerenchyma, but floating leaves and finely dissected leaves are also common. Aquatic plants only thrive in water or in soil that is frequently saturated, and are therefore a common component of swamps and marshlands.
cadherin Any of a class of transmembrane proteins which are dependent on calcium ions (Ca2+) and whose extracellular domains function as mediators of cell–cell adhesion at adherens junctions in eukaryotic tissues.
In Latin America, liberation theology is a socialist tendency within the Roman Catholic Church that emerged in the 1960s. In Chile, Salvador Allende, a physician and candidate for the Socialist Party of Chile, became the first democratically elected Marxist President after presidential elections were held in 1970. However, his government was ousted three years later in a military coup backed by the CIA and the United States government, instituting the right-wing dictatorship of Augusto Pinochet which lasted until the late 1980s. In addition, Michael Manley, a self-described democratic socialist, served as the fourth Prime Minister of Jamaica from 1972 to 1980 and from 1989 to 1992. According to opinion polls, he remains one of Jamaica's most popular Prime Ministers since independence. Eurocommunism became a trend in the 1970s and 1980s in various Western European communist parties which intended to develop a modernised theory and practice of social transformation that was more relevant for a Western European country and less aligned to the influence or control of the Communist Party of the Soviet Union. Outside of Western Europe, it is sometimes referred to as neocommunism. Some communist parties with strong popular support, notably the Italian Communist Party and the Communist Party of Spain, enthusiastically adopted Eurocommunism and the Communist Party of Finland was dominated by Eurocommunists.
Climate change is predicted to have significant effects on global potato production. Like many crops, potatoes are likely to be affected by changes in atmospheric carbon dioxide, temperature and precipitation, as well as interactions between these factors. As well as affecting potatoes directly, climate change will also affect the distributions and populations of many potato diseases and pests. While the potato is less important than maize, rice, wheat and soybeans, which are collectively responsible for around two-thirds of all calories consumed by humans (both directly and indirectly as animal feed), it still is one of the world's most important food crops. Altogether, one 2003 estimate suggests that future (2040–2069) worldwide potato yield would be 18–32% lower than it was at the time, driven by declines in hotter areas like Sub-Saharan Africa, unless farmers and potato cultivars can adapt to the new environment. Potato plants and crop yields are predicted to benefit from the CO2 fertilization effect, which would increase photosynthetic rates and therefore growth, reduce water consumption through lower transpiration from stomata and increase starch content in the edible tubers. However, potatoes are more sensitive to soil water deficits than some other staple crops like wheat. In the UK, the amount of arable land suitable for rainfed potato production is predicted to decrease by at least 75%. These changes are likely to lead to increased demand for irrigation water, particularly during the potato growing season. Potatoes grow best under temperate conditions.

After being elected in November 2024, Trump said he wished to end the Gaza war, telling Israeli prime minister Benjamin Netanyahu to end Israel's invasion within two months and warning Hamas that they would have "all hell to pay" if they did not agree to a ceasefire and release all hostages by Trump's inauguration. Trump's incoming administration joined the Biden administration in pressuring negotiations, and Israel and Hamas agreed to a phased ceasefire on January 15, 2025. In February 2025, Trump proposed an American takeover of Gaza in which the territory's Palestinian population would be relocated to allow for its redevelopment, which was criticized by Egypt and Jordan. The ceasefire lasted until March 18, when Israel launched attacks on Gaza. Trump's special envoy Steve Witkoff blamed Hamas for renewed fighting in Gaza. On May 16, while in Abu Dhabi, United Arab Emirates, Trump said, "We're looking at Gaza. And we're going to get that taken care of. A lot of people are starving." This is an area of tension between President Trump and Prime Minister Benjamin Netanyahu. Israel claims that Hamas systemically raids food aid in order to support its operations, and Israel has put forward a plan of food distributed through a system of hubs run by private contractors and protected by Israeli soldiers. The U.S.-backed Gaza Humanitarian Foundation has been set up to carry out this plan and announced it would be ready to begin operations by the end of May. On July 28, while in Scotland, President Trump said he believed there was starvation occurring in Gaza.

It targets PPARδ, a nuclear receptor involved in lipid and energy metabolism. It does not act primarily on androgen receptors. This distinction separates it from SARMs.
Rodent studies found dose-dependent tumors in several organs. The sponsor discontinued the program over cancer concerns. Human risk from long-term use remains unknown.
Controlled human endurance trials are lacking. Animal studies show increased exercise capacity under some conditions. Anecdotal reports are not equivalent to clinical evidence.
Rodent studies reported increased endurance and fat oxidation after GW501516 exposure. Long-term studies also found higher rates of some tumors, which led to halted development.
