It is these complications that result in huge mortality rates in patients with diabetes, especially vascular ones. This work focuses on diabetic foot ulcers (DFUs), which are one of the most common complications of type 2 diabetes mellitus (T2DM) and cause significant morbidity, mortality, and healthcare costs. The healing of DFUs is hindered by deregulation of nearly all phases of this process because of the hyperglycemic environment. Although therapies currently exist to treat a patient with DFU, they are proving inadequate. In the present work, angiogenesis is highlighted as part of the proliferative phase, which, when diminished, plays an important role in the impaired healing of DFU and other chronic wounds. Therefore, the search for new therapeutic strategies targeting angiogenesis is of great interest. In this study, we provide an overview of molecular targets with therapeutic potential and therapies that act on angiogenesis. To this end, a search of articles in PubMed and Scopus databases from 2018 to 2021 was performed to review angiogenesis as a therapeutic target for DFU.

Although it is primarily seen in the lungs, other organs may also be affected with a lower prevalence. The second most common prevalence of extrapulmonary Tbc cases, nearly 27% of extrapulmonary Tbc cases, are seen in the urogenital system. The most important mechanism introduced in urogenital Tbc pathophysiology is the hematogenous spreading after primary lung infection. After the initial settlement of bacillary in kidney parenchyma, the bacillary may not cause an infection if the host defense is satisfactory or the virulence of bacillary is low. However, the presence of these factors (low host defense or increased bacillary virulence) may cause parenchymal infiltration and granulomatous infection resulting in fibrosis. In addition, caseous necrosis in papilla and calyxes and chronic abscesses in renal parenchyma may also occur as the disease progresses. In addition to stricture in the ureteropelvic junction and ureter, it may spread to the bladder and cause bladder fibrosis and caseous necrosis. Apart from these, urogenital Tbc may be presented with epididymis and prostate involvement in male patients and the involvement of the fallopian tube, cervix, endometrium, and ovaries in female patients. Urogenital Tbc formation and development may take long periods after primary infection. The diagnosis is hard due to no specific findings. Thus, it may cause severe outcomes. The aim of this work was to present an urinary Tbc case with nonspecific symptoms for a long time and caused organ loss. Our case was a 32-year-old female patient who was admitted to the urology outpatient clinic with severe lower urinary system symptoms such as dysuria, frequency, and urgency present for 1 year. She had no additional diseases and surgery history. No pathological findings were observed in the physical examination. Because there was leukocyte positivity in urine analysis, urinary culture was taken and antibiotic treatment was started. Kidney function tests were normal in the blood biochemistry of the patient who had no bacteria growth in the urinary culture. TheHbsAg, antiHIV, and anti-HCV were negative. Since the symptoms recurred, urinary system ultrasonography was taken. Bladder irregularity, bladder wall thickening, hydronephrosis, and parenchymal thinning in the left kidney were observed in the urinary system ultrasonography.Contrasted abdominopelvic computed tomography (CT)was performed. There was left renal hydronephrosis and no ureteral dilatation in abdominopelvic CT. Asymmetrical wall thickeningwas observed in right posterior and left lateralwall in the bladder (Fig. 1). Afterward, intravenous pyelography showed no function in the left kidney (Fig. 2). In the Tc-99m DTPA, radioactivity involvement was not observed in the left kidney.

The objective of this study was to identify the antimicrobial and antioxidant activity of the aqueous extract from urucum seeds and its skin healing potential in exposed cutaneous lesions in rats treated with the gel containing the extract. <b>Methods:</b> Three types of extracts from seeds were made using chloroform, sodium hydroxide, water, and estimated bixin and norbixin. In the presence of antioxidants, antibacterial was observed and then evaluated the skin healing in rats using aqueous extract. <b>Results:</b> Annatto dyes have been evaluated in all three extracts. When the seeds were extracted with chloroform, bixin was detected. If extraction was performed by sodium hydroxide or water, norbixin was detected. For healing use, 10% of aqueous extract was mixed in a gel base. The finding obtained from the antioxidant assay revealed that the activities of the water extract could be used as a source of polyphenolic compounds. In chloroform extract, the antioxidant was not effective because it has weak radical scavengers. With respect to antimicrobial activity, it has been observed that aqueous extract has more effect. For skin healing assay, a total of 3 study groups were tested: negative control group (gel base), positive control group (fibrinase), and test group (gel with urucum aqueous extract). After 7 days of treatment, animals treated with fibrinase had an improvement of 4.7% in total wound area when compared with the negative control while those treated with urucum aqueous extract presented an improvement of 51.55% in comparison. After 14 days, the total wound area of animals within the test group had a decrease of 94.97% when compared with the negative control (gel base) results while the control group presented an improvement of 56.58% in total wound area. These results indicate that wounds treated with urucum aqueous extract were 38.39% more efficient than fibrinase, a cream used for skin healing. <b>Conclusions:</b> It is possible to conclude that gel with aqueous extract is effective in skin healing in rats, being used as a phytotherapic, besides possessing antioxidant and antimicrobial activity.</p>","PeriodicalId":74479,"journal":{"name":"Porto biomedical journal","volume":"8 1","pages":"e183"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/17/ab/pj9-8-e183.PMC10194807.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9502278","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
