Mycorrhizal roots are frequently colonized by fungi of the Phialocephala fortinii s.l.-Acephala applanata species complex (PAC). These ascomycetes are common and widespread colonizers of tree roots. Some PAC strains reduce growth increments of their hosts but are beneficial in protecting roots against pathogens. Nothing is known about the effects of PAC on mycorrhizal fungi and the PAC-mycorrhi...

BACKGROUND The ratio of plasma aldosterone concentration to plasma renin activity (PAC/PRA) is the most common screening test for primary hyperaldosteronism (PHA), but it is not standardized among laboratories. We evaluated new automated assays for the simultaneous measurement of PAC and plasma renin concentration (PRC). METHODS We studied 76 healthy normotensive volunteers and 28 patients wi...

A patient is presented in whom a pulmonary artery catheter (PAC) formed a knot which was fixed in the region of the tricuspid valve chordea. The PAC was successfully and nonsurgically freed from its attachment and removed. A guide wire was introduced by the distal port of the PAC and under fluoroscopy the PAC was manipulated free and then extracted easily.

Noninvasive focused ultrasound stimulation (FUS) can be used to modulate neural activity with high spatial resolution. Phase-amplitude coupling (PAC) between neuronal oscillations is tightly associated with cognitive processes, including learning, attention, and memory. In this study, we investigated the effect of FUS on PAC between neuronal oscillations and established the relationship between...

Background: Periprosthetic infection is the most serious joint replacement complication, occurring in 0.8-1.9% of totalknee arthroplasties (TKAs).This review aims to define the role of preoperative aspiration culture (PAC) for diagnosis of TKA infection.Methods: A PubMed (MEDLINE) search related to TKA infection and PAC was analyzed. The main criteria for selectionwere that the articles were fo...

Pulmonary arterial hypertension (PAH) is a chronic progressive disease that leads to right heart failure and death. Pulmonary arterial capacitance (PAC), defined as stroke volume divided by the pulmonary pulse pressure, has been identified as a prognostic factor in PAH. The impact of changes in PAC over time, however, is unclear. We evaluated changes in PAC over time to determine if such change...

Atrial fibrosis is one of the major pathophysiologic mechanisms underlying progression atrial arrhythmias. We previously demonstrated in a swine model that frequent premature complexes (PACs) promote fibrillation (AF) via and slow conduction. Whether such can be reversed or prevented unknown. To evaluate effect (1) PAC eradication (2) antifibrotic drug pirfenidone (PFD) on frequent, dyssynchron...

Increasing evidence showed a link between arterial elasticity and stiffness and pulse pressure (PP), in which plasma aldosterone may play a role. The observational study aimed to explore the potential relations between plasma aldosterone concentration (PAC) and PP in patients with hypertension. We evaluated the relation between PP and PAC in supine, seated, and upright positions in 195 patients...

RESUMO O sulfato de alumínio (SA) é amplamente utilizado como coagulante no tratamento água abastecimento via ciclo completo. Coagulantes alternativos estão disponíveis mercado, dentre eles o cloreto polialumínio (PAC). Porém, estudos comparativos entre SA e os PACs alta (PAC-AB) baixa (PAC-BB) basicidade em relação à cinética floculação ainda são escassos. Nesse sentido, intuito deste trabalho...
