Introduction Lipoid pneumonia is a clinical condition that may be initially asymptomatic or confused with an infectious or malignant lung disease. Objectives We report four cases of this pathological condition. Methods The first case concerned an 85-year old woman with bilateral confluent pulmonary opacities, ground-glass type. Diagnosis was based on the cytology of the bronchoalveolar lavage fluid followed by its ultrastructural examination. The second case was a 47-year-old man with an isolated pulmonary nodule, which was surgically removed; the diagnosis of lipoid pneumonia was formulated on the basis of the histological and electron microscopy examination...

Recently, dynamic MRI of hyperpolarized (3)He during inhalation revealed an alternation of the image intensity between left and right lungs with a cardiac origin (Sun Y, Butler JP, Ferrigno M, Albert MS, Loring SH. Respir Physiol Neurobiol 185: 468-471, 2013). This effect is investigated further using dynamic and phase-contrast flow MRI with inhaled (3)He during slow inhalations (flow rate ∼100 ml/s) to elucidate airflow dynamics in the main lobes in six healthy subjects. The ventilation MR signal and gas inflow in the left lower lobe (LLL) of the lungs were found to oscillate clearly at the cardiac frequency in all subjects, whereas the MR signals in the other parts of the lungs had a similar oscillatory behavior but were smaller in magnitude and in anti-phase to the signal in the left lower lung...

A new method for the speciation, preconcentration, and separation of Cr(lll) and Cr(VI) species in different matrixes was developed using SPE combined with flame atomic absorption spectrometry. Theprocedure is based on the exchange of Cr(VI) ions as CrO(4)(2-) with CI- ions on Lewatit lonac SR-7 ion-exchange resin. After the oxidation of Cr(lll) to CrO(4)(2-) ions by concentrated H202 in basic medium, the procedure was applied to the determination of total Cr. Cr(lll) was calculated as the difference between the total Cr and Cr(VI) contents...

Hemodynamics are usually evaluated in the supine position at rest. This is only a snapshot of an individual's daily activities. This study describes circulatory adaptation, as assessed by magnetic resonance imaging, to changes in position and exercise. Phase contrast magnetic resonance imaging of blood flow within systemic and pulmonary arteries and veins was performed in 24 healthy volunteers at rest in the prone and supine position and with bicycle exercise in the supine position. No change was seen in systemic blood flow when moving from prone to supine...

Clear cell tumor of the lung is a rare and benign pulmonary tumor; only sporadic cases have been reported. Here, we report the case of a 38-year-old man with recurrent cough, blood-streaked sputum and left chest pain. A chest computed tomography scan showed a round, homogeneous pulmonary mass in the left lower lobe, which exhibited intense heterogeneous enhancement in the arterial phase and homogeneous in the delay phase after injecting a contrast agent. The patient underwent a fine-needle aspiration biopsy and was diagnosed as having a benign clear cell tumor of the lung...

This research explored the role that associative learning may play in human sequence learning. Two-choice serial reaction time tasks were performed under incidental conditions using 2 different sequences. In both cases, an experimental group was trained on 4 subsequences: LLL, LRL, RLR, and RRR for Group "Same" and LLR, LRR, RLL, and RRL for Group "Different," with left and right counterbalanced across participants. To control for sequential effects, we assayed sequence learning by comparing their performance with that of a control group, which had been trained on a pseudorandom ordering, during a test phase in which both experimental and control groups experienced the same subsequences...

The aim of this study was to purify and identify lipolysis-stimulating peptides derived from Flavourzyme®-soy protein isolate (SPI) hydrolysate (F-SPIH). Glycerol release was employed as a marker for lipolysis in 3T3-L1 adipocytes. A higher glycerol release represents a better lipolysis-stimulating activity. The peptide fraction with highest glycerol release obtained from F-SPIH fractionated by sequential ultrafiltration membranes was further purified using gel filtration chromatography and two steps of reverse-phase high-performance liquid chromatography...

We presented the interference setup which can produce interesting two-dimensional patterns in polarization state of the resulting light wave emerging from the setup. The main element of our setup is the Wollaston prism which gives two plane, linearly polarized waves (eigenwaves of both Wollaston's wedges) with linearly changed phase difference between them (along the x-axis). The third wave coming from the second arm of proposed polarization interferometer is linearly or circularly polarized with linearly changed phase difference along the y-axis...

Anionic polymers are valuable components used in cosmetics and health sciences, especially in drug delivery, because of their chemical versatility and low toxicity. However, because of their highly negative charge they pose problems for penetration through hydrophobic barriers such as membranes. We have engineered anionic polymalic acid (PMLA) to penetrate biological membranes. PMLA copolymers of leucine ethyl ester (P/LOEt) or trileucine (P/LLL) show either pH-independent or pH-dependent activity for membrane penetration...

Adrenocortical carcinoma (ACC) is a rare but typically aggressive malignancy. Radical surgery remains the potentially curative option. However, about one third of patients initially present with distant metastases. Regarding to chemotherapy, mitotane alone or in combination with cytotoxic drugs should be the first selection. Meanwhile, a phase lll clinical trial of etoposide, doxorubicin, cisplatin plus mitotane or streptozotocin plus mitotane is currently undergoing worldwide. The study on molecular pathogenesis of ACC is progressing...

BACKGROUND: In Belgium, bladder cancer is the fifth most common cancer in males (5.2%) and the sixth most frequent cause of death from cancer in males (3.8%). Previous epidemiological studies have consistently reported that selenium concentrations were inversely associated with the risk of bladder cancer. This suggests that selenium may also be suitable for chemoprevention of recurrence. METHOD: The SELEBLAT study opened in September 2009 and is still recruiting all patients with non-invasive transitional cell carcinoma of the bladder on TURB operation in 15 Belgian hospitals...
