[Pulmonary Cryptococcosis Treated with Antifungal Drugs After Surgical Resection:Report of a Case].

The patient is an 81-year-old man. He underwent surgery for pancreatic body cancer in 201X and was followed up every six months with computed tomography (CT) imaging. A CT scan in 201X+5 showed a new nodule in S6 of the right lung.

[Emergent Transcatheter Aortic Valve Implantation for Degenerated Surgical Aortic Valve Under Local Anesthesia:Report of a Case].

An 89-year-old man who had undergone aortic valve replacement with a 21 mm Mosaic bioprosthetic valve at another hospital 14 years ago was admitted to the emergency room for a sudden respiratory distress two days prior and was diagnosed with severe aortic regurgitation( AR) caused by valve insufficiency and acute heart failure secondary to low cardiac function. Upon admission, he was found to have severe hypoxia with PaO2 of 40 mmHg range, and transcatheter aortic valve replacement (TAVI, TAV in SAV) with a 20 mm SAPIEN3 was performed under local anesthesia for fear of hypotension while under general anesthesia. After confirming that AR had completely disappeared, the patient was intubated and discharged from the operating room on a mechanical ventilator.

Quorum sensing communication: Bradyrhizobium-Azospirillum interaction via N-acyl-homoserine lactones in the promotion of soybean symbiosis.

Quorum-sensing (QS) mechanisms are important in intra- and inter-specific communication among bacteria. We investigated QS mechanisms in Bradyrhizobium japonicum strain CPAC 15 and Azospirillum brasilense strains Ab-V5 and Ab-V6, used in commercial co-inoculants for the soybean crop in Brazil. A transconjugant of CPAC 15-QS with partial inactivation of N-acyl-homoserine lactones (AHLs) was obtained and several parameters were evaluated; in vitro, CPAC 15 and the transconjugant differed in growth, but not in biofilm formation, and no differences were observed in the symbiotic performance in vivo.

Antioxidant activity and induction of mechanisms of resistance to stresses related to the inoculation with Azospirillum brasilense.

We investigated the effects of Azospirillum brasilense strains Ab-V5 and Ab-V6 in the induction of mechanisms of systemic acquired resistance (SAR) and induced system resistance (ISR) on maize (Zea mays L.) plants. Under normal growth conditions, the treatments consisted of the standard inoculation of cells at sowing, and leaf spray of cells or their metabolites at the V2.

Azospirillum: benefits that go far beyond biological nitrogen fixation.

The genus Azospirillum comprises plant-growth-promoting bacteria (PGPB), which have been broadly studied. The benefits to plants by inoculation with Azospirillum have been primarily attributed to its capacity to fix atmospheric nitrogen, but also to its capacity to synthesize phytohormones, in particular indole-3-acetic acid. Recently, an increasing number of studies has attributed an important role of Azospirillum in conferring to plants tolerance of abiotic and biotic stresses, which may be mediated by phytohormones acting as signaling molecules.
