Fruits form an important part of a healthy human diet as they contain many ingredients with proven pro-health effects such as vitamins, phenolic compounds, organic acids, fiber, and minerals. The purpose of this work was to evaluate the effect of pullulan coating on the quality and shelf life of highbush blueberry during storage. General appearance, weight loss, dry matter, soluble solid content, reducing sugars, content of L-ascorbic acid, phenolic compounds (total phenolics, phenolics acids and anthocyanins) were determined in uncoated and coated blueberries fruits...

In an effort to better restore normal joint function and kinematics, recent emphasis has been placed on surgical techniques that provide a more anatomic reconstruction of the anterior cruciate ligament (ACL). With femoral tunnel placement shown to play a vital role in the biomechanics, stability, and clinical outcomes after ACL reconstruction, approaches that better approximate the ACL's native femoral origin have been adopted. The independent anteromedial portal technique is thought to better position the femoral tunnel within the native ACL footprint and leave the graft more posteroinferior on the wall of the lateral femoral condyle than the more traditional transtibial approach...

This study was aimed at monitoring changes in the quality of strawberry purée preserved by high pressure processing (HPP) and thermal pasteurization (TP) during cold storage (6 °C) and determining its optimal storage period. The storage period of strawberry purée treated at 500 MPa, 50 °C, 15 min based on microbiological changes was 12 weeks. During this period, purée lost 32% of polyphenols, 73% of anthocyanins and entire vitamin C. Color changes described as dE increased up to 5.05 whereas the overall sensory quality decreased by 3 points on a 9-point scale...

BACKGROUND: Multiple reconstruction techniques have been described in the management of chronic scapholunate (SL) instability, either based on the capsulodesis or tenodesis principle. It is uncertain which surgical method produces the best patient outcomes. We describe results of a technique using palmaris longus (PL) tendon for surgical reconstruction of the SL ligament and provide functional outcomes scores. MATERIALS AND METHODS: We surgically reconstructed the SL ligament using a PL tendon graft secured with Mitek(®) bone anchors...

Since the erythrophagocytosis of opsonized erythrocytes is investigated mainly by calculating the phagocytic index using subjective light microscopy evaluation, we present methods for the quantitative and qualitative analysis of human cell erythrophagocytosis. Erythrocytes from two storage periods were used. Using Imaris software, we were able to create a three-dimensional model of erythrophagocytosis. The use of microscopy instead of cytometry revealed a significantly higher number of monocytes and erythrocytes that appeared active in phagocytosis...

Magnesium-based interference screws may be an alternative in anterior/posterior cruciate ligament reconstruction. The well-known osteoconductive effects of biodegradable magnesium alloys may be useful. It was the purpose of this study to evaluate the biomechanical properties of a magnesium based interference screw and compare it to a standard implant. A MgYREZr-alloy interference screw and a standard implant (Milagro®; De Puy Mitek, Raynham, MA, USA) were used for graft fixation. Specimens were placed into a tensile loading fixation of a servohydraulic testing machine...

INTRODUCTION: In various countries, standard doses of anti-D IgG used for postpartum immunoprophylaxis of hemolytic disease of fetus and newborn (HDFN) vary from 100 μg to 300 μg. There are also different regulations concerning FMH assessment, and opinions about applicable tests are inconclusive. METHODS: Three flow cytometry tests (FCTs) with anti-D, anti-HbF, anti-HbF+CA antibodies, and two modifications of microscopic Kleihauer-Betke test (KBT) were used. RESULTS: In all artificial mixtures with known concentrations, FCTs and KBT with counting 10 000 RBCs had similar satisfying sensitivity and specificity...

BACKGROUND: Abdominal bulge after retroperitoneal dissection occurs at a rate of 1% to 56%. Injury to the T11 and T12 nerves is thought to result in abdominal musculature denervation, laxity, and symptomatic abdominal bulge. This complication has become more prevalent because the retroperitoneal approach for spinal surgery has become the preferred approach in specific lumbar and thoracic cases. Current repair techniques fail to address the etiology of abdominal wall laxity, and outcomes are poorly reported...

The nasal valve has long been described as the anatomical boundary most likely to inhibit nasal airflow and lead to subsequent nasal obstruction. Although many procedures can address this area to improve the nasal airway, for over 20 years, suture lateralization of the external nasal valve has been described as a minimally invasive technique that can improve nasal breathing. We report our modification of the standard technique in which we lateralize the placement of the bone-anchored suture and incorporate Gore-Tex within the nasal vestibular incision to prevent tissue migration...

PURPOSE: This cadaveric study compares the biomechanical properties of femoral graft fixation in ACL reconstruction of either quadriceps or hamstring tendon grafts with four different interference screws. The hypothesis was that quadriceps tendon grafts provide at least equal results concerning gap formation during cyclic loading and ultimate failure load compared to hamstring tendon grafts with four different interference screws. METHODS: Eighty porcine femora underwent interference screw fixation of human tendon grafts for ACL reconstruction...

We present a modification and revisit of the Bell Tawse technique for annular ligament reconstruction with triceps autograft for chronic radial head instability. In patients with instability stemming from an incompetent annular ligament, this technique has proved successful to restore stability to the proximal radial capitellar joint as an augment after ensuring normal boney anatomy. Through a lateral Kocher approach, an approximately 10 cm × 4 mm strip of lateral triceps tendon is harvested as a free graft for the reconstruction...

Shoulder instability can be a challenging condition to treat when it becomes refractory to soft-tissue procedures or when bone loss exceeds 25% to 27% of the glenoid. The Bristow-Latarjet procedure has been developed and popularized to deal with these concerns. Traditionally, the procedure has been performed as an open approach; however, this has been recently supplanted by novel arthroscopic techniques. We present a technique for the procedure performed with the patient in a semi-lateral decubitus position that assists with optimal graft placement on the native glenoid...

PURPOSE: Adjustable cortical fixation has gained popularity recently for ACL reconstruction; however, one concern with these types of devices is the potential for laxity occurring post-operatively. An indicator of clinical laxity is cyclic displacement during bench-top mechanical testing. The hypothesis was that the cyclic displacement and maximum strength of different adjustable buttons currently on the market would vary depending on their mechanism of fixation. METHODS: Three devices were studied: Biomet's ToggleLoc with ZipLoop Technology (ZL), Arthrex's TightRope RT (TR), and DePuy Mitek's RIGIDLOOP Adjustable (RLA)...

Suprapubic hernias, parailiac or flank hernias, and lumbar hernias are difficult to repair and are associated with high-recurrence rates owing to difficulty in obtaining substantive overlap and especially mesh fixation due to bone being a margin of the hernia. Orthopedic suture anchors used for ligament reconstruction have been used to attach prosthetic material to bony surfaces and can be used in the repair of these hernias where suture fixation was impossible. A prospective, single institution study of ventral hernia repairs involving bone anchor mesh fixation was performed...
