与仅靶向单一受体的同类药物相比，瑞他鲁肽增加胰高血糖素受体成分，理论上可提高能量消耗并改变脂肪分布。临床中观察到的体重变化是否主要来自该额外机制，目前尚无定论。胃肠道反应是该类药物常见不良事件，试验中通过剂量递增和监测进行管理。停药后体重反弹、个体差异和长期耐受性仍需更多数据。
瑞他鲁肽是一种在研合成肽，同时作用于胰高血糖素样肽-1、葡萄糖依赖性促胰岛素多肽和胰高血糖素受体。该分子属于多受体激动剂类别，尚未获得任何监管机构的上市批准。当前临床开发主要针对肥胖和2型糖尿病，研究代号为LY3437943。已确立的信息包括受体靶点和部分中期试验结果；最终疗效、长期安全性和适用人群仍属开放问题。
开发进程从早期单次和多次给药研究推进至大规模后期试验。公开报告显示，参与者在体重和相关代谢指标上出现变化，但完整数据需经同行评审并接受独立复核。试验设计通常包括随机、双盲和对照设置，以区分药物效应与行为干预。监管提交和标签范围尚未确定；长期维持效果与心血管结局仍是开放问题。
The intended pharmacology combines three signals in one molecule. GLP-1 receptor activation reduces appetite and slows gastric emptying, effects already exploited by approved incretin-based therapies. GIP receptor engagement is associated with improved insulin sensitivity and with direct effects on adipose tissue, although how much it contributes to overall outcomes is still debated. Glucagon receptor agonism raises energy expenditure and supports hepatic lipid handling, a mechanism that also tends to increase glucose output. The triple profile is hypothesized to produce a larger metabolic effect than single or dual agonism, but the relative weight of each receptor in humans is not settled.
Human evidence remains limited to controlled studies. A phase 2 trial in adults with obesity reported large, dose-dependent reductions in body weight over 48 weeks, with gastrointestinal events as the most frequently recorded adverse effect. Phase 3 programs designated TRIUMPH, for obesity, and TRANSCEND, for type 2 diabetes, are intended to confirm efficacy and to characterize safety in larger populations. Related studies are examining conditions such as knee osteoarthritis in people with obesity and metabolic liver disease. Open questions include long-term tolerability, effects on lean mass, and what happens after treatment is stopped.

Published information places retatrutide in clinical development rather than on the market as an approved therapy. Early-stage and mid-stage trials have examined tolerability and changes in body weight, and larger studies continue to report results over time. Open questions include the durability of effects after treatment stops, the composition of weight lost, and cardiovascular outcomes over long periods. Statements about definitive benefit should therefore be treated as provisional. Regulatory status varies by jurisdiction and changes as applications are reviewed.
Retatrutide is an investigational synthetic peptide designed to activate three distinct receptor systems within a single molecule. Its pharmacological profile combines activity at the glucose-dependent insulinotropic polypeptide receptor, the glucagon-like peptide-1 receptor, and the glucagon receptor. This arrangement places it within a broader class of agents often described as multi-agonists, which contrast with compounds that engage one or two targets. Research interest centers on whether simultaneous signaling produces effects that single-receptor agonists cannot achieve alone. A single molecular entity also simplifies manufacturing and delivery logistics compared with combining separate agents.
Development has progressed through early- and mid-stage human studies in adults with obesity and with type 2 diabetes. Published phase 2 data reported reductions in body weight and improvements in glycemic markers over the treatment period. No regulatory agency has approved the compound for any indication, and it remains available only within controlled research settings. Whether benefits observed in trials translate into durable outcomes after treatment stops is not yet established.
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.
=== Europe === In the European Union (EU), the European Medicines Agency (EMA) defines a drug as "orphan" if it is intended for the diagnosis, prevention or treatment of a life-threatening or chronically and seriously debilitating condition affecting not more than 5 in 10,000 EU people. EMA also qualifies a drug as orphan if – without incentives – it would be unlikely that marketing the drug in the EU would generate sufficient benefit for the affected people and for the drug manufacturer to justify the investment.
=== Cleansing === Cleansing is the process of removing dirt, oil, makeup, and other impurities from the skin. Lathering cleansers, a common type of facial cleanser, generate lather when used, thanks to a surfactant level greater than the CMC (critical micelle concentration). These cleansers contain surfactants with short hydrophobic chains, enabling faster and higher levels of lather. Most lathering cleansers on the market use synthetic surfactants designed to be mild to the skin, reducing skin damage compared to naturally derived surfactants. However, they may be less effective at removing oil-soluble makeup. Liquid lathering cleansers clean through the chemical process of emulsification, suspending or emulsifying dirt and oils, thus allowing them to be removed from the skin during the rinse process. Exfoliating cleansers are used to cleanse and exfoliate the skin twice per day, in the morning and evening. There also exist soapless or "no-rinse" cleansers (syndets).
The capacity of this molecule to act as a two-electron carrier (moving between the quinone and quinol form) and a one-electron carrier (moving between the semiquinone and one of these other forms) is central to its role in the electron transport chain due to the iron–sulfur clusters that can only accept one electron at a time and as a free radical–scavenging antioxidant.
Compared with non-parents, parents with children have lower levels of well-being and life satisfaction until children move out of the household, at which point parents have higher well-being and satisfaction. In addition, parents report more feelings of depression and anxiety than non-parents. However, when adults without children are compared to empty nest parents, parenthood is positively associated with emotional well-being. People found parenthood to be more stressful in the 1970s than they did in the 1950s. This is thought to be because of social changes in regards to employment and marital status. Males apparently become less happy after the birth of a child due to added economic pressure and taking on the role of being a parent. A conflict between partners can arise when the couple does not desire traditional roles, or has an increasing number of roles. Unequal responsibilities of child-rearing between men and women account for this difference in satisfaction. Fathers who worked and shared an equal part in child-raising responsibilities were found to be the least satisfied. Research shows that single parents have higher levels of distress and report more mental health problems than married persons. Researchers implemented the Huta & Ryan Scale: Four Eudaimonic Measurement Questionnaire to analyze the participants eudaimonic motives, through motivation towards activities. The investigation was conducted on Canadian university undergraduates. The four eudaimonic pursuits as described by Huta & Ryan are:

=== Treatment approach === Any interventions done are matched with the needs of each individual in an ethical and respected manner. Health belief model encourages increasing individuals' perceived susceptibility to negative health outcomes and making individuals aware of the severity of such negative health behavior outcomes. E.g. through health promotion messages. In addition, the health belief model suggests the need to focus on the benefits of health behaviors and the fact that barriers to action are easily overcome. The theory of planned behavior suggests using persuasive messages for tackling behavioral beliefs to increase the readiness to perform a behavior, called intentions. The theory of planned behavior advocates the need to tackle normative beliefs and control beliefs in any attempt to change behavior. Challenging the normative beliefs is not enough but to follow through the intention with self-efficacy from individual's mastery in problem solving and task completion is important to bring about a positive change. Self efficacy is often cemented through standard persuasive techniques.
Nortilidine is the major active metabolite of tilidine. It is formed from tilidine by demethylation in the liver. The racemate has opioid analgesic effects roughly equivalent in potency to that of morphine. The (1R,2S)-isomer has NMDA antagonist activity. The drug also acts as a dopamine reuptake inhibitor. The reversed-ester of nortilidine is also known, as is the corresponding analogue with the cyclohexene ring replaced by cyclopentane, which have almost identical properties to nortilidine.
Bukele is a proponent of Central American reunification, an ideology that calls for Costa Rica, El Salvador, Guatemala, Honduras, and Nicaragua to reestablish the Federal Republic of Central America, and has stated that Central America should be "one single nation" in some of his speeches. In January 2024, he reaffirmed on Twitter that he believes that Central America should unite as a single country; each individual country is small and lacks natural resources, but a unified Central American population and biodiversity would help strengthen the region. In his tweet, Bukele conceded that he needed "the will of the peoples" ("la voluntad de los pueblos") of Central America to unite the region. Bukele was the president pro tempore of the Central American Integration System (SICA), an economic and political organization, from 5 June to 22 December 2019. In February 2020, Bukele signed an agreement with the Guatemalan government to remove restrictions on border crossings between El Salvador and Guatemala and designate flights between the countries as "domestic" flights to promote tourism. The agreement gave Bukele's government the ability to build a port on the Caribbean Sea in Guatemalan territory, that would give El Salvador access to the Atlantic Ocean. He described the agreement as "the greatest step to the integration of Central America in the last 180 years" ("el mayor paso en la integración de Centroamérica en los últimos 180 años").
Half-Life: Opposing Force is an expansion pack for the first-person shooter game Half-Life (1998). It was developed by Gearbox Software and published by Sierra On-Line for Windows on November 19, 1999. Opposing Force was the first expansion for Half-Life and was announced in April 1999. Lead designer Randy Pitchford believed Gearbox was selected to develop Opposing Force because Valve, the creators of Half-Life, wanted to concentrate on their future projects. Over the course of development, Gearbox brought in a variety of talent from other areas of the video games industry to help bolster various aspects of design. Opposing Force portrays the events of Half-Life from the perspective of a U.S. Marine, one of the enemy characters in the original, assigned to the Hazardous Environment Combat Unit (HECU). The player character, Adrian Shephard, is sent in to neutralize the Black Mesa Research Facility when a scientific mishap causes it to be invaded by aliens, but quickly finds that the Marines are outnumbered and slowly being beaten back by a second alien race and black operations units. Opposing Force was received well by critics, with many describing it as the new benchmark title for expansion packs, in a similar fashion to how Half-Life revolutionized the first-person shooter genre. Other reviewers, however, thought that, despite its accomplishments, it still suffered from the negative aspects of other expansion packs.
(‰) The amount of liquid-vapor equilibrium fractionation for hydrogen isotopes is about 8x that of oxygen isotopes at Earth surface temperatures, which reflects the relative mass differences of the two isotope systems: 2H is 100% heavier than 1H, 18O is 12.5% heavier than 16O. Above the boundary layer, there is a transition zone with relative humidity less than 100%, and there is a kinetic isotope fractionation associated with water vapor diffusion from the boundary layer to the transition zone, which is empirically related to the relative humidity (h):

This is a list of dried foods. Food drying is a method of food preservation that works by removing water from the food, which inhibits the growth of bacteria and has been practiced worldwide since ancient times to preserve food. Where or when dehydration as a food preservation technique was invented has been lost to time, but the earliest known practice of food drying is 12000 BC by inhabitants of the modern Middle East and Asia.
== Plasmid preparation == Chloramphenicol is often used when growing E. coli cultures intended for plasmid preparation. Chloramphenicol halts protein synthesis, but allows plasmids with a relaxed origin of replication to keep replicating, thus improving yield.
The lichen's survival is closely linked to its dependence on atmospheric humidity. Lacking specialized water-absorbing structures such as roots or stomata, X. parietina absorbs ambient moisture for metabolic activity. When humidity drops, the lichen enters a dormant state, suspending photosynthesis until moisture returns. This poikilohydric strategy enables it to withstand prolonged dry periods, although growth and reproduction are largely confined to humid conditions. In wetter climates, continuous hydration supports ongoing metabolism and faster thallus expansion. Environmental factors—air temperature, wind, and evaporative demand—influence its physiology: higher temperatures accelerate water loss, and strong, dry winds intensify desiccation, particularly in low-altitude coastal regions; conversely, moderate winds with adequate humidity can enhance gaseous exchange and temporarily boost photosynthetic efficiency. This balance between moisture availability and air movement is a key determinant of lichen growth rates across different habitats. The thallus of X. parietina progresses through distinct ontogenetic stages that reflect its ecological adaptations. In the juvenile and immature phases, the lichen establishes its foliose form and develops a homeomeric structure with a protective upper crust. As it advances to virginal stages, the characteristic rosette shape forms.
Prednisone is a synthetic glucocorticoid used for its anti-inflammatory and immunosuppressive properties. Prednisone is a prodrug; it is metabolised in the liver by 11-β-HSD to prednisolone, the active drug. Prednisone has no substantial biological effects until converted via hepatic metabolism to prednisolone.
==== Hydrometallurgical metals reclamation ==== This method involves the use of aqueous solutions to remove the desired metals from the cathode. The most common reagent is sulfuric acid. Factors that affect the leaching rate include the concentration of the acid, time, temperature, solid-to-liquid-ratio, and reducing agent. It is experimentally proven that H2O2 acts as a reducing agent to speed up the rate of leaching through the reaction:
