retatrutide 是一种人工合成的多肽，设计目标是同时作用于 GIP、GLP-1 与胰高血糖素三种受体。这种三重激动设计试图把多条代谢通路的调节整合进单一分子，而不是只依赖一种肠促胰素受体。分子骨架以天然肽序列为基础，经过非天然氨基酸替换和脂肪酸侧链修饰，以获得更长的作用时间。该方向属于多受体激动剂研究的一部分，与双重激动剂的工作并行推进。
Retatrutide is an investigational peptide developed by a pharmaceutical company as a multi-receptor agonist for treating obesity and type 2 diabetes. The compound emerged from research into gut-hormone analogues that act on several receptors simultaneously rather than on a single target. Early preclinical work examined how combined activity at three distinct receptors might produce greater metabolic effects than single-receptor compounds. Published phase 2 results have described substantial reductions in body weight among participants, although the compound remains unapproved in most jurisdictions as of the mid-2020s.
Pharmacologically, retatrutide acts as a triple agonist at the glucagon-like peptide-1 receptor, the glucose-dependent insulinotropic polypeptide receptor, and the glucagon receptor. Activation of the first two receptors is associated with improved insulin secretion and reduced appetite. The glucagon receptor component is thought to increase energy expenditure, a mechanism that distinguishes this molecule from dual-agonist compounds. Researchers continue to investigate how the three activities interact and whether the combined profile offers advantages that justify additional clinical testing.

A person was killed and 19 others, including two military personnel were injured in a suicide VBIED attack by Hafiz Gul Bahadur Group on the Bannu–Miranshah road. Pakistani Police forces neutralized two IEDs with 140+ kilograms and an 8kg explosive device in Bannu District. On the same day, some tribal elders and former military personnel in Afghanistan's border provinces said that the Taliban had asked them to support its conflict with Pakistan and to organize public protests against the country. According to them, as tensions between the Taliban and Pakistan continued, Taliban officials in Khost, Paktika, Paktia, and Nangarhar provinces reportedly held meetings with tribal elders and influential figures to encourage participation in protests against Pakistan. Some tribal elders described the outreach as unusual, saying they had not been invited to official meetings since the Taliban returned to power. Taliban officials in Kabul were also said to have asked former Afghan government officials and former members of the House of Representatives to publicly support the Taliban in its war with Pakistan. Former Afghan soldiers in Paktika and Khost provinces also state that the Taliban were seeking out and forcibly taking ex-soldiers, particularly those trained to operate heavy weapons such as mortars and artillery, to border areas to assist in the conflict. Afghan news outlet reported that Taliban forces people in Badakhshan province to raise anti-Pakistan slogans.
===== Rail transport ===== The government intends to start a new wave of investment in the expansion of the Brazilian railway network, with the strategy being to increase investments in railway lines led by the ministry of transport; within the New PAC, the government intends to invest R$94.2 billion in 35 projects, R$55.1 billion by 2026 and more $39.1 billion in subsequent years, the majority of the investments will be through the private sector. The focus, this time, will be the passenger transport, the newspaper Poder360 found that there are 7 most advanced passenger train projects, stretches averaging 100 km connecting municipalities and metropolitan regions, among these, the longest would be the one that connects Fortaleza with Sobral, in Ceará, a stretch of more than 200 km, the others would be in the states of Maranhão, Bahia, Rio de Janeiro, Paraná, Rio Grande do Sul and the Federal District. Currently, there are only two regular passenger lines: between Vitória and Belo Horizonte, and between São Luís and Parauapebas (PA), both are also used to transport cargo; for the construction of these lines, the government sees it as essential to take advantage of the existing railway infrastructure, aimed at transporting cargo, but which is underutilized or in a precarious state of maintenance.

==== Saline breast prosthesis ==== The first commercial model of a breast prosthesis filled with saline solution was made by Laboratoires Arion of France, which they publicly presented as a prosthetic medical device in 1964. The modern models of prosthetic breasts filled saline-solution are made with vulcanized shells composed of a silicone elastomer of great elasticity, like that of the skin and tissues of a woman's breast. In an augmentation mammoplasty to emplace a saline breast-prosthesis, the plastic surgeon employs a short incision to the chest wall, through that incision the surgeon then inserts the collapsed, empty prosthetic breast into the breast-implant socket, then fills the implanted breast prosthesis with saline solution. The surgeon then contours the implanted prosthetic breast for anatomical symmetry, and afterwards sutures shut the insertion incision. Functionally, the implantation of a saline breast-prosthesis yields good-to-excellent results of increased breast-size, a smoother contour for the breast hemisphere, and anatomic symmetry; however, such a breast augmentation might ripple and wrinkle the skin envelope of the breast, cosmetic defects that make noticeable the presence of the prosthetic breast to the eye and to the touch. Such cosmetic defects of the breast surgery usually occur among women with a small volume of adipose tissue in their breast hemispheres.
There are two mechanisms that protect sickle cell carriers from malaria. One is that the parasite is hindered from growing and reproducing in a carrier's red blood cells; another is that a carrier's red cells show signs of damage when infected, and are detected and destroyed as they pass through the spleen.

=== South Africa === In South Africa learnerships to qualify as a Phlebotomy Technician are offered by many public and private educational institutions as well as by private academies owned up by pathology laboratories (such as Ampath Laboratories, Lancet, PathCare) and healthcare service providers (such as Netcare, South African National Blood Service). Some of the larger retail pharmacy chains offering in-store clinical services (such as Clicks, Dis-Chem) also provide training for aspirant phlebotomists. Certification can be obtained from a number of examination and testing institutions. To work as a phlebotomist in South Africa, registration with the Health Professions Council of South Africa (HPCSA) is required.

In ancient Greece, it was regarded as a magic and poisonous plant that was used in religious ceremonies. Initiates of the cult of Demeter would most likely have taken opium. This is due to the fact that it is said that Demeter ate the opium plant when her daughter, Persephone, was abducted so that she could fall asleep and forget her grief. For the citizens of Mycenea, the opium poppy was an object of worship that was depicted on royal tombs. Eventually, the Greco-Roman world began to accept opium for its medicinal qualities too. Helen of Sparta is said to have used the "nepenthes drug" which some authors believe to be a concoction containing opium. Within archaeological sites of ancient Sparta, there have been findings of pendants adorned with opium poppy capsules, affirming this belief. In the third century BCE, Theophrastus refers to it and discusses the process of obtaining the sap through crushing it, as the process of incising the poppy was lost until 40 CE. The process was relearned by Scribonius Largus, physician to the Emperor Claudius, who writes about the process of obtaining opium. Both of these authors note that opium induced sleep and numbed pain, disregarding its effects on the brain. However, other writings regard its effects on the mind to be important, such as those from Diagoras of Melos and Erasistratus, who believed that addiction to opium would harm the brain and body, urging others to not use it at all. Hippocrates believed that opium was a natural remedy that could cure certain ailments, but also advocated for its use sparingly.
Civilians returned to power in 1985 when José Sarney assumed the presidency. He became unpopular during his tenure through failure to control the economic crisis and hyperinflation he inherited from the military regime. Sarney's unsuccessful government led to the election in 1989 of the almost-unknown Fernando Collor, who was subsequently impeached by the National Congress in 1992. Collor was succeeded by his vice-president, Itamar Franco, who appointed Fernando Henrique Cardoso as Minister of Finance. In 1994, Cardoso devised a highly successful Plano Real that, after decades of failed economic plans made by previous governments attempting to curb hyperinflation, finally stabilized the Brazilian economy. Cardoso won the 1994 election, and again in 1998.
Eptifibatide is used to reduce the risk of acute cardiac ischemic events (death and/or myocardial infarction) in patients with unstable angina or non-ST-segment-elevation (e.g., non-Q-wave) myocardial infarction (i.e., non-ST-segment elevation acute coronary syndromes) both in patients who are to receive non surgery (conservative) medical treatment and those undergoing percutaneous coronary intervention (PCI). The drug is usually applied together with aspirin or clopidogrel and (low molecular weight or unfractionated) heparin. Additionally, the usual supportive treatment consisting of applications of nitrates, beta-blockers, opioid analgesics and/or benzodiazepines should be employed as indicated. Angiographic evaluation and other intensive diagnostic procedures may be considered a first line task before initiating therapy with eptifibatide. The drug should exclusively be used in hospitalized patients both because of the serious degree of patients' illness and because of the possible side-effects of eptifibatide.
