We have identified and sequenced the genes encoding the aggregation-promoting factor (APF) protein from six different strains of Lactobacillus johnsonii and Lactobacillus gasseri. Both species harbor two apf genes, apf1 and apf2, which are in the same orientation and encode proteins of 257 to 326 amino acids. Multiple alignments of the deduced amino acid sequences of these apf genes demonstrate...

OBJECTIVE To study and compare the effects of different demineralization-inhibition methods on the shear bond strength (SBS) and fracture mode of an adhesive used to bond orthodontic brackets to demineralized enamel surfaces. METHODS Eighty freshly extracted, human maxillary premolars were divided into 4 equal groups and demineralized over the course of 21 days. Brackets were bonded to the de...

The therapy of inflammatory bowel disease, particularly with tumor necrosis factor (TNF) blockers, may be associated with a number of cutaneous adverse effects, including psoriasis-like, eczema-like, and lichenoid eruptions. Other rare skin complications are neutrophilic dermatoses such as amicrobial pustulosis of the folds (APF), which is a chronic relapsing pustular disorder classified in thi...

This paper presents a thorough study of the adaptive sliding mode technique with application to single-phase shunt active power filter APF . Based on the basic principle of single-phase shunt APF, the approximate dynamic model is derived. Amodel reference adaptive sliding mode control algorithm is proposed to implement the harmonic compensation for the single-phase shunt APF. Thismethodwill use...

This paper analyses the characteristics of LCL filter in active power filter (APF) and provides an accurate for mula to determine the resonant frequency of system. Based on a single-phase equivalent circuit model, a systematic approach to design APF with LCL filter is proposed. Total inductance is determined by the capability of APF. Moreover, damping ratio, resonant frequency and attenuation d...

AIM To review the dental literature in terms of efficacy of soft tissue augmentation procedures around dental implants and in partially edentulous sites. METHODS A Medline search was performed for human studies augmenting keratinized mucosa (KM) and soft tissue volume around implants and in partially edentulous areas. Due to heterogeneity in between the studies, no meta-analyses could be perf...

Muscle flap transposition is one of the surgical treatment options for empyema with alveolarpleural fistula (APF) or bronchopleural fistula (BPF). This surgical procedure is invasive because it is typically performed by standard thoracotomy. We performed video-assisted thoracoscopic surgery (VATS) debridement, decortication, and obliteration of an empyema cavity using a pedicled latissimus dors...

Due to the wide spread of power electronics equipment in modern electrical systems, the increase of the harmonics disturbance in the ac mains currents has became a major concern due to the adverse effects on all equipment. This paper presents the analysis and simulation using Matlab Simulink of a three-phase four wire neutral clamped active power filter (APF) compensating the harmonics and reac...

Glycoamino acid analogues of the Thomsen-Friedenreich antigen disaccharide, where the 4' and 4″ hydroxyl groups were substituted with fluorine or hydrogen, were synthesized and incorporated into the asialylated antiproliferative factor (as-APF), a biologically active form of APF, a glycopeptide found in the urine of patients with interstitial cystitis. Various strategies were employed to incorp...

Hepatic arterioportal fistulae (APF) are abnormal communications between the hepatic artery and the portal vein. In this report, we present the second case in the literature of a symptomatic APF presenting as a gastric variceal bleeding. A 55-year-old female presented to our facility with hematemesis. Upper endoscopy revealed a bleeding gastric varix. A computed tomography scan identified a lar...
