1. Role of the reducing agent in tungsten extraction by chlorination with chlorine from an ore enriched by physical means
Abstract The effect of three reducing agents (sulphur dioxide, pyrite and carbon) on tungsten extraction from a scheelite-wolframite concentrate with chlorine gas was assessed. A low-grade ore (0.9% w/w WO3) was collected in the San Martín department, San Luis Province, Argentina, and subsequently enriched by physical means (65.73% w/w WO3). The minerals id

2. Minimally invasive lymphocele drainage using the Da Vinci® single port platform: step-by- step technique
ABSTRACT Background: Reports in the literature describe lymphocele formation in up to half of patients following pelvic lymph node dissection (PLND) (1) in robotic-assisted radical prostatectomy (RARP), with 1-2% requiring intervention (2). The advantage of surgical approach is permanent excision of the lymphocele capsule and fewer days with pelvic drains c

6. A review on medicinal plants used for treating ototoxicity and acoustic trauma induced hearing loss
Hearing loss induced by chemotherapy and acoustic trauma is mainly associated with two factors, free radical formation and apoptosis pathway activation. Despite numerous efforts on reducing the effects of these factors, no definite strategy is still determined to interfere with and control these processes. In recent studies, various protective agents, includ

12. Targeted therapy with a selective BCL-2 inhibitor in older patients with acute myeloid leukemia
ABSTRACT Background: Older patients with acute myeloid leukemia are particularly difficult to treat, as they have a high risk of comorbidities, poor performance status and less tolerability to chemotherapy, as well as a more aggressive disease biology, responsible for the resistance to treatment. There is a need to explore novel therapeutic agents that are
