The distinction between native collagen and collagen peptides matters for behavior in water and in analytical tests. Native collagen is a rigid, triple-helical protein that is largely insoluble in cold water. Peptides lack that organized helix and dissolve readily, forming clear or slightly hazy solutions. Because hydrolysis shortens chains, viscosity falls and gelation behavior changes. The term collagen peptide does not specify a single molecular species; it describes a family of hydrolysates with variable chain lengths and properties.
Collagen peptides are short-chain proteins produced by hydrolyzing native collagen, the main structural protein in skin, bone, tendon, and cartilage. The hydrolysis step breaks the triple-helical structure and cleaves longer chains into smaller fragments. The resulting material is water-soluble and typically has an average molecular weight in the low kilodalton range. Commercial ingredients are often described as hydrolyzed collagen or collagen hydrolysate. Amino acid composition remains rich in glycine, proline, and hydroxyproline, though the ordered helical arrangement is largely lost.
Raw collagen for peptide production comes from bovine hide, porcine skin, fish skin and scales, and sometimes poultry cartilage. The material is cleaned, extracted, and treated with acid, alkali, or enzymes to break peptide bonds. Enzymatic hydrolysis using proteases allows better control of fragment size than purely chemical methods. After hydrolysis, the liquid is filtered, concentrated, and dried into a powder. Source and processing conditions influence color, odor, molecular weight distribution, and amino acid profile.
Several terms describe related products, and their distinctions matter. Gelatin is partially hydrolyzed collagen that still forms a gel when dissolved in hot water and cooled. Collagen peptides, also called collagen hydrolysate, are further broken down and remain soluble without gelling. The term 'collagen' alone usually refers to the intact, insoluble protein. Commercial collagen peptides are often standardized by molecular weight range rather than by a single molecular species, so batch-to-batch variation occurs.
Collagen peptides are short chains of amino acids produced by breaking down native collagen, a structural protein found in skin, bone, and connective tissue. The hydrolysis process cleaves the long triple-helical collagen molecule into smaller fragments. These fragments typically range from about 2 to 20 kilodaltons in molecular weight. Unlike intact collagen, collagen peptides dissolve in water and do not form gels. Commercial preparations appear as powders, granules, or liquids.

== Treatments == When infection attacks the body, anti-infective drugs can suppress the infection. Several broad types of anti-infective drugs exist, depending on the type of organism targeted; they include antibacterial (antibiotic; including antitubercular), antiviral, antifungal and antiparasitic (including antiprotozoal and antihelminthic) agents. Depending on the severity and the type of infection, the antibiotic may be given by mouth or by injection, or may be applied topically. Severe infections of the brain are usually treated with intravenous antibiotics. Sometimes, multiple antibiotics are used in case there is resistance to one antibiotic. Antibiotics only work for bacteria and do not affect viruses. Antibiotics work by slowing down the multiplication of bacteria or killing the bacteria. The most common classes of antibiotics used in medicine include penicillin, cephalosporins, aminoglycosides, macrolides, quinolones and tetracyclines. Not all infections require treatment, and for many self-limiting infections the treatment may cause more side-effects than benefits. Antimicrobial stewardship is the concept that healthcare providers should treat an infection with an antimicrobial that specifically works well for the target pathogen for the shortest amount of time and to only treat when there is a known or highly suspected pathogen that will respond to the medication.
=== Gluconeogenesis === Glucagon is traditionally a catabolic hormone, but also stimulates the anabolic process of gluconeogenesis by the liver, and to a lesser extent the kidney cortex and intestines, during starvation to prevent low blood sugar. It is the process of converting pyruvate into glucose. Pyruvate can come from the breakdown of glucose, lactate, amino acids, or glycerol. The gluconeogenesis pathway has many reversible enzymatic processes in common with glycolysis, but it is not the process of glycolysis in reverse. It uses different irreversible enzymes to ensure the overall pathway runs in one direction only.
A Ukrainian international law scholar, Alexander Merezhko, has developed a project called the International Convention on Prohibition of Cyberwar in Internet. According to this project, cyberwar is defined as the use of Internet and related technological means by one state against the political, economic, technological and information sovereignty and independence of another state. Professor Merezhko's project suggests that the Internet ought to remain free from warfare tactics and be treated as an international landmark. He states that the Internet (cyberspace) is a "common heritage of mankind". On the February 2017 RSA Conference Microsoft president Brad Smith suggested global rules – a "Digital Geneva Convention" – for cyber attacks that "ban the nation-state hacking of all the civilian aspects of our economic and political infrastructures". He also stated that an independent organization could investigate and publicly disclose evidence that attributes nation-state attacks to specific countries. Furthermore, he said that the technology sector should collectively and neutrally work together to protect Internet users and pledge to remain neutral in conflict and not aid governments in offensive activity and to adopt a coordinated disclosure process for software and hardware vulnerabilities. A fact-binding body has also been proposed to regulate cyber operations.
=== Myxedema coma === Myxedema coma or severe decompensated hypothyroidism usually requires admission to the intensive care unit, close observation and treatment of abnormalities in breathing, temperature control, blood pressure, and sodium levels. Mechanical ventilation may be required, as well as fluid replacement, vasopressor agents, careful rewarming, and corticosteroids (for possible adrenal insufficiency which can occur together with hypothyroidism). Careful correction of low sodium levels may be achieved with hypertonic saline solutions or vasopressin receptor antagonists. For rapid treatment of hypothyroidism, levothyroxine or liothyronine may be administered intravenously, particularly if the level of consciousness is too low to be able to safely swallow medication. While administration through a nasogastric tube is possible, this may be unsafe and is discouraged.
A football pitch, or field, can be used as a man-in-the-street unit of area. The standard FIFA football pitch for international matches is 105 m (344 ft) long by 68 m (223 ft) wide (7,140 m2 or 0.714 ha or 1.76 acres); FIFA allows for a variance of up to 5 m (16.4 ft) in length in either direction and 7 m (23.0 ft) more or 4 m (13.1 ft) less in width (and larger departures if the pitch is not used for international competition), which generally results in the association football pitch generally only being used for order of magnitude comparisons. An American football field, including both end zones, is 360 by 160 ft (120.0 by 53.3 yd; 109.7 by 48.8 m), or 57,600 square feet (5,350 m2) (0.535 hectares or 1.32 acres). A Canadian football field is 65 yards (59 m) wide and 110 yards (100 m) long with end zones adding a combined 40 yards (37 m) to the length, making it 87,750 square feet (8,152 m2) or 0.8215 ha (2.030 acres). An Australian rules football field may be approximately 150 metres (160 yd) (or more) long goal to goal and 135 metres (148 yd) (or more) wide, although the field's elliptical nature reduces its area to a certain extent. A 150-by-135-metre (164 by 148 yd) football field has an area of approximately 15,900 m2 (1.59 ha; 3.9 acres), twice the area of a Canadian football field and three times that of an American football field.

=== Recruitment and spending policy === Youth development and scouring for talent abroad is central to Wenger's recruitment policy. He relies on a network of scouts and personal contacts to find and attract talented footballers to play under him. Wenger's strategy is aided by data; for instance, the decision to sign Flamini in 2004 came about as he was looking at statistics to find an understudy to Vieira. To examine the mental state of a young footballer, he uses psychometric tests conducted by psychologist Jacques Crevoisier once every two years. Wenger prides himself on nurturing talent, saying in an interview: "I believe one of the best things about managing people is that we can influence lives in a positive way. That's basically what a manager is about. When I can do that, I am very happy". In his early managerial years, Wenger recognised the potential of football in Africa, which influenced his transfer dealings at Monaco. On the recommendation of Claude Le Roy, he signed Liberian George Weah, who later became the first African to be named FIFA World Player of the Year. Weah, while receiving his award from FIFA president João Havelange and vice-president Lennart Johansson invited Wenger up to the stage, spontaneously giving his medal to the manager, as a token of his appreciation. During his final years at Monaco, Wenger worked with Roger Mendy, a Senegalese defender regarded in 1991 as one of the ten best African footballers by France Football, and Nigerian Victor Ikpeba, a forward who earnt the accolade of African Player of the Year.
==== Modi–Trump relationship (2025–present) ==== On July 30, 2025, US President Donald Trump announced that Indian products would be subject to 25% tariffs upon arrival in the United States starting August 1, and that a "penalty" would be added for the purchase of Russian oil.
=== Lawsuits === From 2019 to 2024, Maria Francesca Gioia, a former medical student acting as a pro se plaintiff, filed nine product liability lawsuits against Janssen Pharmaceuticals and related parties. She alleged that taking Invega Sustenna (paliperidone palmitate) caused her memory loss, hypothyroidism, Horner's syndrome, nerve damage, motor tremors, vocal tics, confusion, loss of taste and sensation, post-traumatic stress disorder, and metabolic syndrome (including hypertension, diabetes, and stroke), which ended her career as a primary care physician. All nine lawsuits were dismissed on procedural grounds: Gioia I–II for failure to state a claim, Gioia III for failure to prosecute, and Gioia IV–V for lack of subject matter jurisdiction. The court also noted that the side effects she alleged were already listed on Invega's FDA-approved warning label. In September 2024, Cassandra Fameux filed a criminal complaint alleging that her husband, a Michigan anesthesiologist, had forcibly injected her with unprescribed Invega Sustenna on multiple occasions between 2017 and 2021. A subsequent police investigation led to a recommendation that he be charged with domestic assault. In May and June 2022, Adilah Patton, a 28‑year‑old pretrial detainee in Indianapolis, was forcibly injected twice with unprescribed Invega Sustenna while in custody at the Marion County Adult Detention Center. A federal lawsuit filed on her behalf alleges that the injections were administered without a medical assessment, a prescription, or the consent of her court‑appointed guardian.
Descemet's Stripping (Automated) Endothelial Keratoplasty (DSEK/DSAEK) in which the diseased Descemet's membrane is removed and replaced by a healthy donor posterior transplant. The transplant tissue can be prepared by a surgeon's hand or ordered already prepared for surgery. Ocular Systems was the first organization to deliver prepared grafts for surgery in 2005. DSEK/DSAEK uses only a small incision that is either self-sealing or may be closed with a few sutures. The small incision offers several benefits over traditional methods of corneal transplant such as penetrating keratoplasty. Because the procedure is less invasive, DSAEK leaves the eye much stronger and less prone to injury than full-thickness transplants. New medical devices such as the EndoSaver (patent pending) are designed to ease process of inserting endothelial tissue into the cornea. Additionally, DSAEK has a more rapid rate of visual recovery. Vision is typically restored in one to six months rather than one to two years. Descemet Membrane Endothelial Keratoplasty (DMEK) is the most recent EK technique in which an isolated Descemet's membrane is transplanted. The DMEK procedure is a 'like for like' replacement of the diseased part of the cornea with visual rehabilitation to 20/40 or better in 90% of cases and 20/25 or better in 60% of cases within the first three months. Rejection rates are lower (1%) and visual recovery is faster than any other form of corneal transplantation.

Luis Moroder grew up in the small ethnic community of Ladins in the Dolomites of South Tyrol in Northern Italy. As a boy he became fascinated by natural science while accompanying his father Heinrich on mineralogical, paleontological and archaeological excursions in the mountain world of his homeland with discoveries of various fossiles that are exemplary shown in the Museum Gherdeina. Moroder was married to Anne Marie Hellrigl-Moroder with one daughter. He died on 18 May 2024, at the age of 83. 1995: Max-Bergmann-Medal of the MBK Society 2004: Josef Rudinger Award of the European Peptide Society 2011: Doctor honoris causa, University of Cergy-Pontoise, Paris 2018: Akabori Memorial Lecture Award of the Japanese Peptide Society 2020: Ernesto Scoffone Award of the Italian Peptide Society
How the secretion of motilin is regulated is largely unknown, although some studies suggest that an alkaline pH in the duodenum stimulates its release. However, at low pH it inhibits gastric motor activity, whereas at high pH it has a stimulatory effect. Some studies in dogs have shown that motilin is released during fasting or interdigestive period, and intake of food during this period can prevent the secretion of motilin. Intravenous injection of glucose, which increases the release of insulin, is also found to inhibit cyclic elevation of plasma motilin. Other studies on dogs have also suggested that motilin acted as endogenous ligand in positive feedback mechanism to stimulate the release of more motilin. In dogs and cats, motilin secretion is stimulated by hydrogen ions (protons) and lipids when the animal is in a "fed" state. However, during fasting, motilin is periodically released into the serum to initiate phase III of the migrating motor complex.
The kappa and lambda light chains undergo rearrangements of the V and J gene segments. In this process, a functional Vlambda can combine with four functional Jλ –Cλ combinations. On the other hands, Vk gene segments can join with either one of the Jk functional gene segments. The overall rearrangements result in a gene segment order from 5 prime to 3 prime end. These are a short leader (L) exon, a noncoding sequence (intron), a joined VJ segment, a second intron, and the constant region. There is a promoter upstream from each leader gene segment. The leader exon is important in the transcription of light chain by the RNA polymerase. This sequence is translated to guide the polypeptide to the internal environment of the endoplasmic reticulum, but is cleaved and absent from the mature protein. To remain with coding sequence only, the introns are removed during RNA- processing and repairing.
62. Tirzepatide. Farzam K(1), Patel P. In: StatPearls [Internet]. Treasure Island (FL): StatPearls Publishing; 2026 Jan–. 2026 Sep 14. Author information: (1)McMaster University Tirzepatide is a medication approved by the US Food and Drug Administration (FDA) for the treatment of type 2 diabetes, obesity, and obstructive sleep apnea. As a dual agonist of the glucagon-like peptide-1 and glucose-dependent insulinotropic polypeptide receptors, it improves glycemic control and reduces body weight in patients with type 2 diabetes. Administered once weekly via subcutaneous injection with incremental dose adjustments, tirzepatide is used as a second-line diabetes medication. Tirzepatide is not approved for the treatment of type 1 diabetes and has not been adequately studied in patients with pancreatitis. Common adverse effects are gastrointestinal, including nausea, vomiting, and diarrhea. This activity provides an overview of the indications, mechanism of action, administration, adverse effects, contraindications, drug interactions, and considerations for specific patient populations. The activity also enhances clinicians’ competence in administering tirzepatide, monitoring treatment response and adverse effects, and managing patients with type 2 diabetes to improve patient outcomes and safety.

== History == The magazine was launched in October 1993 by Steve Jarratt, a long-time video games journalist who has launched several other magazines for Future. The artwork for the cover of the magazine's 100th issue was specially provided by Shigeru Miyamoto. The 200th issue was released in March 2009 with 200 different covers, each commemorating a single game; 199 variants were in general circulation, and one was exclusive to subscribers. Only 200 magazines were printed with each cover, sufficient to more than satisfy Edge's circulation of 28,898. In October 2003, the then-editor of Edge, João Diniz-Sanches, left the magazine along with deputy editor David McCarthy and other staff writers. After the walkout, the editorship of Edge passed back to Tony Mott, who had been editor prior to Diniz-Sanches. The only team member to remain was Margaret Robertson, who in 2006 replaced Mott as editor. In May 2007, Robertson stepped down as editor and was replaced by Tony Mott, taking over as editor for the third time. Alex Wiltshire was the magazine's editor from May 2012 to March 2013, followed by Nathan Brown. Jen Simpkins took over the editor's role from Nathan Brown in April 2020. Between 1995 and 2002, some of the content from the UK edition of Edge was published in the United States as Next Generation. In 2007, Future's US subsidiary, Future US began re-publishing selected recent Edge features on the Next Generation website; the Edge website and blog were subsequently incorporated into the NextGen site.

Collagen is a long, triple-helical structural protein. Collagen peptides are shorter fragments made by hydrolysis, which removes the helix and improves water solubility. The two materials differ in molecular size, viscosity, and behavior in solution.
No. Chain length, amino acid profile, and trace composition vary with raw material and hydrolysis conditions. Products from fish, bovine, and porcine sources can differ in odor, color, and thermal behavior. The term covers a broad family rather than one uniform substance.
Glycine, proline, and hydroxyproline are especially abundant. Hydroxyproline is uncommon in most other proteins and is often used as a marker for collagen content. The peptides also contain varying amounts of alanine, arginine, and other residues.
No. Native collagen is a large, triple-helical protein that is insoluble in water. Collagen peptides are shorter fragments produced by hydrolysis, and they dissolve readily. Digestion further breaks these peptides into amino acids and small peptides.
