Patellofemoral (PF) osteoarthritis (OA) is a somewhat predominant illness, affecting up to 24% of women and 11% ofmen over the age of 55 years who suffer from symptomatic knee OA. The purposes of this narrative overview are tosummarize the present situation of patellofemoral arthroplasty (PFA) in the treatment of solitary PF-OA, and to givean account of the clinical results of...

Evaluation of the pistillate flower abscission (PFA) potential of UC-67-13 and UC-67-11 was continued at two sites. At a high PFA site UC-67-13 PFA was only moderately lower than Serr for the third year. UC-67-11 demonstrated low PFA potential for a seconq year at this site. Higher PFA potential of UC-67-13 than UC-67 -11 was also found at a second site for a second year. No further evaluation ...

Since phosphonoformic acid (PFA) acts as a specific competitive inhibitor of Na+-Pi co-transport across renal brush-border membrane (BBM), we employed the [14C]PFA as a probe to determine the mechanism of its interaction with rat renal BBM. The binding of [14C]PFA to BBM vesicles (BBMV), with Na+ present in extravesicular medium (Na+o), was time- and temperature-dependent. The replacement of Na...

Psychological First Aid (PFA) is the recommended immediate psychosocial response during crises. As PFA is now widely implemented in crises worldwide, there are increasing calls to evaluate its effectiveness. World Vision used PFA as a fundamental component of their emergency response following the 2014 conflict in Gaza. Anecdotal reports from Gaza suggest a range of benefits for those who recei...

Current therapeutics and prophylactics for malaria are under severe challenge as a result of the rapid emergence of drug-resistant parasites. The human malaria parasite Plasmodium falciparum expresses two neutral aminopeptidases, PfA-M1 and PfA-M17, which function in regulating the intracellular pool of amino acids required for growth and development inside the red blood cell. These enzymes are...

For a semi-Pfa an set, i.e., a real semianalytic set de ned by equations and inequalities between Pfa an functions in an open domain G, the frontier and closure in G are represented as semi-Pfa an sets. The complexity of this representation is estimated in terms of the complexity of the original set. Introduction. Pfa an functions introduced by Khovanskii [K] are analytic functions satisfying a...

Phosphonoformate (PFA) is an effective antiviral agent that is used clinically in AIDS chemotherapy under the names of Foscarnet and Foscavir.1 Although the primary indication is AIDS-related human cytomegalovirus (HCMV) infection, PFA is also effective against HIV itself. PFA is proposed to act via inhibition of reverse transcriptase in HIV and DNA polymerase in herpes simplex virus (HSV) and ...

The Platelet Function Analyzer (PFA-100) is increasingly being used in the workup of patients with a bleeding diathesis. A profound knowledge of the possible diagnostic performance of this test is essential in order to make sound clinical decisions based on its results. It was the aim of this study to systematically review the published literature and provide valid estimates of the diagnostic p...

The present study aimed to examine the training effects of a didactic and simulation-based psychological first aid (PFA) program. Based on the competency-based model, the study sought to examine whether the PFA training would enhance knowledge, skills, and attitudes. Study 1 examined the training effects of the PFA program in a sample of undergraduate and graduate students in psychology. Study ...

BACKGROUND The lack of association found in several cohort studies between dietary saturated fat and coronary heart disease (CHD) risk has renewed debate over the link between dietary fats and CHD. METHODS AND FINDINGS We assessed the relationship between plasma phospholipid fatty acid (PFA) concentration and incident CHD using a nested case control design within a prospective study (EPIC-Nor...
