Dyeing wastewater is one of the most important environmental problems in the textile industry. This wastewater contains harmful pollutants that can damage human health and the environment. Electrocoagulation (EC) is a promising technology for dyeing wastewater treatment. This technology passes an electric current through the wastewater, which generates metal hydroxides that act as coagulants to remove pollutants. This article first introduces the EC system and its operation mechanism, then discusses the components that affect the system's performance in removing dye and chemical oxygen demand. The article also summarizes the studies that have been conducted on the use of this process in the treatment of textile dyeing wastewater. In addition, the economic aspects of the EC process and recommendations for its improvement are provided. Finally, the challenges and prospects of the process are discussed. This article provides an effective overview of the current advances and achievements in the EC process for dyeing wastewater treatment, which provides new insights into improving dyeing wastewater treatment with promising environmental applications.

Persian Medicine (PM) offers a unique perspective on gynecological disorders, prompting the need for scientific validation of complementary approaches. This paper synthesizes research on the efficacy and safety of PM interventions for oligomenorrhea and abnormal uterine bleeding. This paper reports on a collaborative initiative involving PM experts and gynecology/obstetrics specialists. The program consisted of two expert panels addressing oligomenorrhea and abnormal uterine bleeding, employing the expert panel method. PM experts presented clinical trial papers relevant to each panel, facilitating a comprehensive review and critique of available scientific evidence. This process sparked a scientific discussion and exchange of opinions among the participating experts. Thirteen clinical trial articles had explored PM interventions in abnormal uterine bleeding, covering Persian Golnar, Golnar capsules, plantain, lentils, myrtle, purslane, pomegranate peel, frankincense-ginger, quince, ginger, chamomile, and cupping therapy. Additionally, nine articles on oligomenorrhea encompassed interventions like anise-celery, sesame, black seed oil, Fomentex herbal tea, Aslaq, oregano, fennel, Agnogel, and fennel plus dry cupping. Utilizing PM interventions for gynecologic diseases requires rigorous diagnostic evaluations and therapeutic measures. The necessity for further clinical trials is emphasized to confirm the effectiveness and safety of these interventions. Collaborative efforts between PM specialists and gynecologists are vital for the logical progression of PM within the health system.

Textile and dyeing industries have made significant progress in recent years, and a large amount of dyes are consumed by these industries. The poor stabilization of dyes leads to the entry of large amounts of them into wastewater. Between different processes for dyeing wastewater treatment, anaerobic treatment is considered an efficient method. Among the anaerobic processes, upflow anaerobic sludge blanket reactor (UASB) is very popular due to its high efficiency in removing dyes, chemical oxygen demand, and other pollutants in textile wastewater, as well as the ability to combine with other textile wastewater treatment methods to improve the quality of the effluent. This study investigates the performance of UASB reactor in dyeing wastewater treatment, dye removal mechanism, and operational parameters. Then, a review of the studies conducted in this field is conducted. Finally, the challenges and prospects ahead are stated. The results and achievements of UASB systems presented in this study can provide new insights into improving UASB performance in dye wastewater treatment with an environmental perspective.

We tried to evaluate prevalence and characteristics of Iranian HIV infected patients with retinitis due to opportunistic infections. In this cross sectional study, we evaluated 106 HIV infected patients via indirect ophthalmoscopy and slit lamp examination by 90 lens to find retinitis cases. General information and results of ophthalmologic examination were analyzed. Prevalence of retinitis due to opportunistic infections was 6.6%: cytomegalovirus (CMV) retinitis 1.88%, toxoplasmosis retinochoroiditis 1.88% and tuberculosis chorioretinitis 2.83%. CD4 count was higher than 50 cell/µlit in both cases with CMV retinitis. Along with increasing survival in the HIV infected patients, the prevalence of complications such as ocular manifestation due to opportunistic infections are increasing and must be more considered.
