Published: February 2013

ortho-Arylation of ortho-substituted benzoic acids is a challenging process due to the tendency of the reaction products toward Pd-catalyzed protodecarboxylation. A simple method for preventing decarboxylation in sterically hindered benzoic acids is reported. The method described represents a reliable and broadly applicable entry to 2-aryl-6-substituted benzoic acids.

Detrimental effects of terminal heat stress could be mitigated by exogenous application of synthetic compounds by preserving cell membrane integrity and protecting against oxidative damage. A field experiment was conducted to test the application of seven synthetic compounds on wheat growth traits: (1) thiourea (20 mM and 40mM); (2) potassium nitrate (1% and 2%); (3) sodium nitroprusside (400 μg mL-1 and 800μg mL-1 ); (4) dithiothreitol (25 ppm and 50ppm); (5) salicylic acid (100 ppm and 200ppm); (6) thioglycolic acid (200 ppm and 500ppm); and (7) putrescine (4 mM and 6mM). These compounds were applied at the anthesis and grain-filling stages to enhance physio-biochemical traits and yield attributes of wheat (Triticum aestivum ) cvs GW-11 and GW-496 under terminal heat stress.

Importance: The phase 3 randomized EMBARK trial evaluated enzalutamide with or without leuprolide in high-risk nonmetastatic hormone-sensitive prostate cancer. Eligibility relied on conventional imaging, which underdetects metastatic disease compared with prostate-specific membrane antigen-positron emission tomography (PSMA-PET).

Objective: To describe the staging information obtained by PSMA-PET/computed tomography (PSMA-PET/CT) in a patient cohort eligible for the EMBARK trial.

Background: Traumatic brain injury (TBI) due to external forces is a major cause of morbidity and mortality among people of all age groups, worldwide. Multiple biological processes like neuroinflammation, mitochondrial dysfunction, oxidative stress, amyloid β (Aβ) production, and tau hyperphosphorylation are involved in the pathogenesis of TBI. The role of neuroinflammation and oxidative stress has been suggested in the pathophysiology of brain injury-induced cognitive dysfunction.
