Prophylaxis against Pneumocystis jirovecii pneumonia (PCP) is recommended for at least 4-12 months after solid organ transplant. In our center, renal transplant recipients receive only 1 month of post-transplant trimethoprim-sulfamethoxazole, which also may provide limited protection against Nocardia. We identified only 4 PCP cases and 4 Nocardia cases in 1352 patients receiving renal and renal...

Allene (H2C═C═CH2; a-C3H4) and propyne (CH3C≡CH; p-C3H4) are important species in various chemical environments. In combustion processes, the reactions of hydroxyl radicals with a-C3H4 and p-C3H4 are critical in the overall fuel oxidation system. In this work, rate coefficients of OH radicals with allene (OH + H2C═C═CH2 → products) and propyne (OH + CH3C≡CH → products) were measured behind refl...

Introduction: Breastfeeding is an important principle in pediatric health. It decreases their mortality and protect them fromm diseases in the first 6-month of life. This study aimed to determined Maternal Knowledge and practice in Mashhad City about Breast-feeding in first 6 -month of Infant's life.   Materials and Methods: This Analytic study was conducted on 105 mothers who had a child ...

Ni et al . (Research Articles, 20 March 2020, p. 1352) report bulk trap densities of 10 11 cm –3 and an increase in interfacial by one to four orders magnitude from drive-level capacitance profiling lead halide perovskites. From electrostatic arguments, we show that the results are not but a consequence geometrical charge injection into perovskite layer.
