Article Synopsis
  • Growing evidence suggests that consuming ultra-processed foods may increase the risk of renal cell carcinoma (RCC) incidence and mortality, although research on this connection has been limited.
  • In a study involving over 100,000 US adults, participants with the highest intake of ultra-processed foods showed a higher likelihood of developing RCC and dying from it compared to those with the lowest intake.
  • The findings indicate that reducing ultra-processed food consumption could be a key strategy for preventing RCC.

Male erectile dysfunction (ED) caused by cavernous nerve injury is a common complication of pelvic surgery, radiotherapy, transurethral surgery or other operations. However, clinical treatment for iatrogenic or traumatic male ED is difficult and not satisfactory. Many studies have shown that curcumin can promote the repair and regeneration of peripheral nerves; however, whether curcumin can rescue cavernous nerve injury is unknown, and the poor bioavailability of curcumin limits its application in vivo.

As one of the most important members of Phthalate esters (PAEs), di-(2-ethylhexyl) phthalate (DEHP) is widely used in plastics and known as a male reproductive toxicant. Many studies have shown that soybean isoflavones (SI) can rescue the testicular injury caused by DEHP, but the underlying mechanism is unknown. Because methylation is one of the most important mechanisms for maintaining normal biological functions, we studied whether methylation is involved in testicular injury induced by DEHP and whether SI could counter testicular impairment in peripubertal male Sprague Dawley rats.

Di-(2-ethylhexyl) phthalate is representative of Phthalate esters (PAEs), which is one of the most widely used plasticizer and known to act as a reproductive toxicant. However, little is known about the toxicity and pathological process of DEHP exposure in male reproductive system in terms of different concentrations and time points. In this study, peripubertal male Sprague Dawley rats were continually exposed to different DEHP doses (100 mg/kg, 500 mg/kg, and 900 mg/kg) and periods (7 days, 14 days, 21 days, 28 days, and 35 days) during critical periods for sexual maturity.
