SR9009 is a synthetic small molecule studied as an agonist of the nuclear receptors REV-ERBα and REV-ERBβ, also called NR1D1 and NR1D2. These receptors help regulate circadian rhythms and metabolic gene programs. The compound was developed for laboratory research, not as an approved therapeutic. Its identity is distinct from steroid hormones and selective androgen receptor modulators. Scientific interest centers on how REV-ERB activation changes gene expression in cells and animal models.
At the molecular level, SR9009 binds the ligand-binding domain of REV-ERB and strengthens recruitment of corepressor proteins such as NCoR and HDAC3. This increases repression of target genes, including Bmal1 and other clock-controlled and metabolic genes. In rodent studies, such changes have been linked to altered lipid handling, glucose metabolism, and energy expenditure. The precise chain of events between receptor binding and whole-body effects remains an active area of research. Findings in animals do not automatically translate to humans.
SR9009 is a synthetic small molecule studied as a REV-ERB agonist. REV-ERBα and REV-ERBβ are nuclear receptors that help regulate circadian rhythms and metabolic gene expression. The compound was identified in academic screening efforts to find synthetic ligands for these receptors. In cell and animal studies, SR9009 alters transcription of genes involved in lipid and glucose metabolism, and it can shift circadian behavior. It is not an approved therapeutic agent.
Mechanistically, SR9009 binds the ligand-binding domain of REV-ERBα/β and enhances recruitment of corepressor complexes. This represses target genes rather than activating them. Because REV-ERB proteins normally compete with ROR proteins at shared response elements, the net effect depends on tissue and timing. Researchers use SR9009 to probe how nuclear receptor signaling links the clock to metabolism, inflammation, and muscle biology. Findings are largely preclinical, and the precise contribution of each receptor subtype remains under study.
SR9009 is frequently discussed in fitness and research-chemical contexts, yet it has no approved medical indication. Regulatory agencies have not authorized it for human use, and it is not a standard prescription drug. Some sports organizations list it as a prohibited substance because of its potential performance-enhancing properties. Published human data are sparse, so claims about its effects in people often rely on animal models or anecdotal reports. Quality and identity of online materials can vary widely.

SR9009 is a synthetic small molecule developed as a REV-ERB agonist. It binds to REV-ERBα and REV-ERBβ, nuclear receptors that help regulate circadian rhythms and metabolic gene expression. In cell and animal studies, the compound alters lipid and glucose handling and influences skeletal muscle oxidative capacity. Its exact effects in humans remain largely uncharacterized because controlled clinical trials have not been reported. The molecule is frequently described in preclinical literature as a metabolic modulator.
Research interest in SR9009 grew from studies showing improved running endurance in mice after short treatment periods. Those experiments linked the compound to increased mitochondrial content and fatty acid oxidation in muscle, but the findings come from animal models and specific dosing schedules. Independent replication has been limited, and the pathways connecting REV-ERB activation to exercise performance are still being mapped. Whether similar responses occur in humans is an open question.
Preclinical reports have linked SR9009 to improved endurance and altered energy expenditure in rodents. Such findings have prompted interest in whether REV-ERB activation can influence skeletal muscle metabolism. However, the reported effects depend on dose, route, and experimental model, and replication across laboratories is limited. Human trials have not established comparable outcomes, so claims about exercise performance remain speculative. The absence of controlled human data is a central limitation in interpreting these observations.
The mechanism of action involves binding to REV-ERB receptors and recruiting corepressor complexes, which represses target gene transcription. This contrasts with many nuclear receptor agonists that activate transcription. Downstream effects may include changes in autophagy, mitochondrial biogenesis, and lipid handling, but the precise pathways remain an active area of study. Whether these molecular events translate into meaningful physiological effects in humans is unresolved. Most evidence comes from cultured cells and rodent models rather than human participants.
SR9009 is a synthetic small molecule that acts on the nuclear receptors REV-ERBα and REV-ERBβ. These receptors are part of the circadian clock machinery and normally repress transcription of certain target genes. In laboratory research, SR9009 is used as a chemical tool to study how REV-ERB activity influences metabolism, inflammation, and daily biological rhythms. The compound is not an approved medicine, and its effects in humans remain largely uncharacterized. It is often described as an investigational agent rather than a therapeutic product.
REV-ERB proteins typically suppress gene expression by recruiting corepressor complexes to DNA response elements. SR9009 binds these receptors and strengthens that repressive action in cell-based assays. Studies in rodents have reported changes in lipid handling, mitochondrial function, and exercise capacity after treatment. Such findings are often cited as evidence for metabolic effects, but species differences and limited pharmacokinetic data make direct translation to humans uncertain. Researchers continue to examine which effects are robust and which depend on specific experimental conditions.
SR9009 is frequently discussed alongside other REV-ERB ligands, including synthetic agonists and natural heme-related molecules. Its selectivity for REV-ERB over related nuclear receptors has been measured in binding and reporter assays, though off-target activity at higher concentrations is possible. The compound is prohibited in sport by the World Anti-Doping Agency, and it is not approved for any medical use in major jurisdictions. Products sold online may be labeled as research chemicals, and their identity and purity are not guaranteed by regulatory review.
Identity and purity of SR9009 samples are usually checked with chromatographic and spectrometric methods. High-performance liquid chromatography can separate the compound from related impurities, while mass spectrometry provides molecular mass confirmation. Nuclear magnetic resonance spectroscopy may be used for structural verification in research settings. No single method proves biological activity, and certificates of analysis should be reviewed alongside raw data. Independent testing is often needed because online products vary widely.
SR9009 stability depends on temperature, moisture, light, and solvent. Solid material is generally kept cool and dry, while solutions may require protection from repeated warming and cooling. Degradation can appear as color changes, precipitate, or new chromatographic peaks. Researchers should follow supplier instructions and their own stability data. Long-term storage conditions for human use have not been established because the compound lacks approved clinical formulation.
SR9009 is supplied as a solid research chemical, often in milligram quantities. Laboratories typically weigh it in a controlled environment because fine powders can disperse. Stock solutions are commonly prepared in dimethyl sulfoxide and stored in small aliquots to reduce freeze-thaw cycles. Personal protective equipment and chemical fume hoods are standard when handling unknown or potent compounds. These practices address laboratory safety rather than human use.
In 2012, Kahala signed a franchising deal with Phoenix-based America's Taco Shop. In 2013, a controlling interest in Kahala Corp. was purchased by the Serruya family of Canada. The Serruyas own and founded Yogen Früz, a chain with 1400 stores around the world. At that time, Michael Serruya became Chairman and Co-CEO of Kahala Corp. Shortly thereafter, Co-CEO Kevin Blackwell left the company. The Serruya family changed the company name from Kahala Corp to Kahala Brands to better align the focus of the business. In June 2015, Kahala Brands purchased Planet Smoothie and Tasti D-Lite. This acquisition added 128 new locations to the overall company store count and increased the total of smoothie-focused locations to over 400 worldwide. Just a few months later in November 2015, Kahala Brands purchased the gourmet coffee and smoothie brand Maui Wowi. At the time of the acquisition, Maui Wowi had with 400 mobile carts and 29 standalone retail units that operated by 200 franchisees. The following month, Kahala acquired Pinkberry in December. In July 2016, MTY Food Group Inc. of Montreal, Quebec in Canada purchased Kahala Brands for approximately US$310 million. Under the deal, Kahala remained in its headquarters in Scottsdale, Arizona while MTY's US operations was moved into Kahala's offices. Kahala's Chief Operating Officer Jeff Smit was chosen to lead the US operations of the combined entity.
Wood fibre, produced from steam friction of wood, is an efficient organic substrate for hydroponics. It has the advantage that it keeps its structure for a very long time. Wood wool (i.e. wood slivers) have been used since the earliest days of the hydroponics research. However, more recent research suggests that wood fibre may have detrimental effects on "plant growth regulators".
=== Genetic predisposition === The genetic locus most significantly associated with Sjögren’s is the major histocompatibility complex/human leukocyte antigen (MHC/HLA) region, as demonstrated by the preliminary results of the first genome-wide association study. This study included data from a discovery cohort of 395 patients of European ancestry with primary Sjögren's disease, and 1,975 healthy control individuals, and from a replication study that comprised 1,234 cases and 4,779 healthy controls. Associations with polymorphisms located at six independent loci were also detected; IRF5, STAT4, BLK, IL12A, TNIP1, and CXCR5. This also suggested the activation of the innate immune system, notably through the IFN system, B-cell activation through CXCR5-directed recruitment to lymphoid follicles and B-cell receptor (BCR) activation involving BLK, and T-cell activation owing to HLA susceptibility and the IL-12-IFN-γ-axis. Patients of different ethnic origins carry different HLA-susceptibility alleles, of which HLA-DR and HLA-DQ are involved in the pathogenesis of Sjögren's disease. For example, patients from Northern and Western Europe and North America show a high prevalence of B8, DRw52, and DR3 genes. HLA class II alleles are associated with the presence of specific subsets of autoantibodies, rather than with the disease itself. Autoantibodies refer to the loss of B-cell tolerance leading to the production of antibodies directed against diverse organ-specific and organ-nonspecific antigens.

== History of human tissue == In humans with non-injured tissues, the tissue naturally regenerates over time; by default, new available cells replace expended cells. For example, the body regenerates a full bone within ten years, while non-injured skin tissue is regenerated within two weeks. With injured tissue, the body usually has a different response. This emergency response usually involves building a degree of scar tissue over a time period longer than a regenerative response, as has been proven clinically and via observation. There are many more historical and nuanced understandings about regeneration processes. In full thickness wounds that are under 2 mm, regeneration generally occurs before scarring. In 2008, in full thickness wounds over 3 mm, it was found that a wound needed a material inserted in order to induce full tissue regeneration. Whereas third degree burns heal slowly by scarring, in 2016 it was known that full thickness fractional photothermolysis holes heal without scarring. Up to 40% of full thickness skin can be removed without scarring in an area, in a fractional pattern via coring of tissue. Some human organs and tissues regenerate rather than simply scar, as a result of injury. These include the liver, fingertips, and endometrium. More information is now known regarding the passive replacement of tissues in the human body, as well as the mechanics of stem cells. Advances in research have enabled the induced regeneration of many more tissues and organs than previously thought possible.
== Research == There is ongoing research into several potential benefits of candesartan beyond established indications. Candesartan is being investigated for its neuroprotective and anti-inflammatory properties. In an early Alzheimer's disease mouse model, candesartan significantly reduced amyloid burden and inflammation and it is being examined as a potential treatment for early Alzheimer's. Rat models indicate that candesartan may have neuroprotective benefits that mitigate certain central mechanisms of ageing and senescence. Additionally, candesartan has shown potential therapeutic applications as an anti-anxiety agent. In a double-blind, placebo-controlled, randomized study, candesartan induced regression of left ventricular hypertrophy, and improved both LV function and exercise tolerance with no side effects in patients with non-obstructive hypertrophic cardiomyopathy. The unique anti-oxidative and anti-inflammatory effects of Candesartan are shown to offer superior renoprotection of chronic renal inflammation, and in ultrahigh doses and in a multidrug context, could be investigated as potentially inducing remission of chronic kidney disease.

=== Origins: early 1960s–1969 === The roots of the New Riders can be traced back to the early 1960s Peninsula folk/beatnik scene centered on Stanford University's now-defunct Perry Lane housing complex in Menlo Park, California where future Grateful Dead guitarist Jerry Garcia often played gigs with like-minded guitarist David Nelson. The young John Dawson (also known as "Marmaduke") also played some concerts with Garcia, Nelson, and their compatriots while visiting relatives on summer vacation. Enamored of the sounds of Bakersfield-style country music, Dawson would turn his older friends on to the work of Merle Haggard and Buck Owens and provided a vital link between Timothy Leary's International Federation for Internal Freedom in Millbrook, New York (Dawson having boarded at the Millbrook School), and the Menlo Park bohemian coterie nurtured by Ken Kesey. Inspired by American folk music, rock and roll, and blues, Garcia formed the Grateful Dead (initially known as The Warlocks) with blues singer Ron "Pigpen" McKernan, while Nelson joined the similarly inclined New Delhi River Band (which would eventually come to include bassist Dave Torbert) shortly thereafter.
=== Probability === Step-growth polymerization is a random process, so we can use statistics to calculate the probability of finding a chain with x-structural units ("x-mer") as a function of time or conversion.

It is now generally acknowledged that by itself, the low protein theory does not adequately account for the pathogenesis of kwashiorkor. More complex deficiencies are at work. These have still not been established. Social factors are also relevant and ignorance of nutrition can be a cause. A case was described where parents who fed their child cassava failed to recognize malnutrition because of the edema caused by the syndrome and thought the child was well-nourished despite the development of kwashiorkor.
