Patellofemoral pain syndrome (PFPS) is one of the most common diseases that cause pain in the knee joint. At present, there is no specific diagnostic measure. The diagnosis of patellofemoral pain syndrome may be considered when imaging is performed without cartilage, ligament and soft tissue injuries. The etiology includes abnormalities of the patellar motion caused by various anatomical abnormalities, such as abnormal patellar position, increased Q angle, and excessive valgus foot. Dysfunction of the lower extremity muscles such as the imbalance of the four biceps and the dysfunction of the gluteal muscles also play an important role in the development of patellofemoral pain syndrome...

Anterior knee pain, with or without joint crepitus during squatting, is the common clinical feature in the individuals with patellofemoral pain syndrome (PFPS). Altered lower extremity alignment and lumbo-pelvic-thigh muscles motor control is often associated with PFPS. Although current interventions recommend individual muscle activation and strength training exercises, the reported benefits of cocontraction-based exercises in PFPS is limited. This might be due to the long-standing hypothesis that exercise-induced cocontraction of thigh muscles may induce a negative effect by increasing the joint contact forces in individuals with knee osteoarthritis...

The diversity of pulsed-field profiles (PFPs) within non-typhoidal Salmonella subtypes influences epidemiological analyses of Salmonella outbreaks. Therefore, determining the PFP diversity of each Salmonella serovar is important when evaluating current circulating strains. This study examined the PFP diversity of three important public health Salmonella enterica subspecies enterica serovars, S. Enteritidis (n=177), S. Infantis (n=205), and S. Corvallis (n=90), using pulsed-field gel electrophoresis. Isolates were collected from several sources, primarily from chicken-derived samples, in the Kyushu-Okinawa region of Japan between 1989 and 2005...

INTRODUCTION: Although measuring vasti muscle onset may reveal whether pain relief is associated with altering this parameter during activities in subjects with patellofemoral pain syndrome (PFPS), it may be necessary to determine whether the inherent properties of the dominant leg influences the reliability of measuring VMO-VL muscle onset. The aim of the present study was to examine the effect of leg predomination on reliability testing of the VMO-VL muscle onset measurement during single leg squatting in healthy subjects...

Weak hip muscle strength and excessive hip motion during running have been suggested as potential risk factors for developing patellofemoral pain syndrome (PFPS) in females, but not males. There is conflicting evidence on the relationship between hip strength and hip kinematics, which may be partly due to sex differences in the relationship between these parameters. Hip, pelvis, and trunk kinematics were collected while 60 healthy, habitual runners (23 females, 37 males) ran overground, and isometric hip abduction and external rotation strengths were measured bilaterally...

Patellofemoral pain (PFP) is a frequent cause of anterior knee pain in athletes, which affects patients with and without structural patellofemoral joint (PFJ) damage. Most younger patients do not have any structural changes to the PFJ, such as an increased Q angle and a cartilage damage. This clinical entity is known as patellofemoral pain syndrome (PFPS). Older patients usually present with signs of patellofemoral osteoarthritis (PFOA). A key factor in PFPS development is dynamic valgus of the lower extremity, which leads to lateral patellar maltracking...

BACKGROUND: The pPT23A family of plasmids appears to be indigenous to the plant pathogen Pseudomonas syringae and these plasmids are widely distributed and widely transferred among pathovars of P. syringae and related species. pPT23A-family plasmids (PFPs) are sources of accessory genes for their hosts that can include genes important for virulence and epiphytic colonization of plant leaf surfaces. The occurrence of repeated sequences including duplicated insertion sequences on PFPs has made obtaining closed plasmid genome sequences difficult...

Pleurotus ferulae is an edible mushroom and has been used in Uygur medicine for a long time. In this study, we purified polysaccharides from P. ferulae (PFPS) and investigated its structural characteristics. We obtained a homogeneous PFPS with a molecular weight of around 1600 kDa and prominent characteristic polysaccharide groups, which mainly contained glucose (97%), followed by mannose and galactose (3%). Both (1)H and (13)C NMR spectra indicated that PFPS contained both α- and β-anomeric configurations...
