It is very common to observe this condition in teenagers, but regardless of age, if the causing condition is met, acne can occur at any point in life. The characteristic feature of all types of acne is it starts with inflammation of the skin. These inflammatory marks (like black spots, pores, small scars, etc.) leave behind even when acne disappears. Plants like vegetables and flowers are naturally rich in different types of polyphenolic compounds called flavonoids. These flavonoids have various key functions, from guiding cell movement to maintaining oxidative pressure in the body. In this study, we discuss six types of flavonoids that have the potential to be used as med-icine for the treatment of different kinds of skin breakouts. Moreover, the result of molecular docking of different proteins that have an association with acne is also discussed.</p>","PeriodicalId":101326,"journal":{"name":"Infectious disorders drug targets","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142305513","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This action is performed by mitochondria through the oxidative phosphor-ylation (OXPHOS) of the respiratory chain (RC). Based on the functioning of the cell, the number of mitochondria varies up to thousands in number. Mutations in the mitochondrial DNA (mtDNA) and/or nuclear DNA (nDNA) genes may lead to the generation of primary mitochondrial disease (PMD) that affects the structure and function of mitochondria. The di-agnosis of such mitochondrial diseases occurs in early childhood and it can lead to serious, fetal and multi-organ diseases. Understanding epigenetic events and changes in the pathway can help improve the effectiveness of treatment. However, there are several reasons lack of the disease symptoms (age, sign, symptoms, morbidity and lethality), restricted availability of pre-clinical models along with extensive phenotypes that hamper the development of efficient drugs. Despite the introduction of new treatments and the encouraging results of treatments and therapies, there is no effective cure for PMD.

The current treatment protocols for pulmonary tuberculosis are quite effective, even though the treatment requires 3-6 months.

Tuberculous meningitis is one of the very few diseases attributable to bacteria that have a very high short-term mortality rate among diagnosed patients, even after treatment with antibiotics that are effective for pulmonary tuberculosis. For example, rifampicin is highly effective for the treatment of pulmonary tuberculosis, but its effectiveness for the treatment of tuberculous meningitis is much lower.

An effective survey of accessible information is conducted in this way based on re-view questions. A number of 372 articles were found on the web, and 32 articles were used in the final analysis. Overall, the standard of hand hygiene is set at 20.49%. Difficulties identified for the people in low or middle-income countries are poor awareness and sound information about hand hygiene, lack of resources including water, soap, hand scrubbing gel, etc., as mis-interpretations related to hand hygiene practices.

The free evidence-based practice states that to lower the danger of contamination, hand hygiene should be properly adhered to.
