Abstract
PURPOSE To investigate the correlation between stage and histopathological characteristics of patients with lung cancer and local recurrence, as well as the incidence and the characteristics of local recurrence along with the possibility of surgical retreatment. METHODS Studied were 51 patients with locally relapsing lung cancer, initially treated surgically from 2003 to 2007. The operations performed ranged from conservative wedge resections, standard lobectomies and pneumonectomies to extensive resections of the entire lung and chest wall. All patients underwent regular follow-up including thoracic CT scan every 3 months. RESULTS All patients were diagnosed with local recurrence after a median of 10 months (range 1-30) after primary surgery with curative intent. There was no statistically significant link between type of surgery and time to local recurrence. Patients with pathological stage I,II, and IIIa had a significantly longer time to local recurrence than those with stage IIIb and IV. Local recurrence sites were the bronchial stump, mediastinal lymph nodes, the remaining lung parenchyma, chest wall and a combination of these. Surgical retreatment was possible in 20 of 51 patients (39.27percnt;). Chest wall was the commonest localization (20 of 51; 39.2%), also the most frequent in the group of surgically retreated patients (13 of 20; 65%). Squamous cell cancer (SCC) was the predominant histological type (38 of 51; 74.5%), followed by adenocarcinoma (9 of 51; 17.7%). CONCLUSION SCC is the commonest locally relapsing lung cancer. The type of the initial surgical procedure didn't have any impact on the incidence of local recurrence, but the extent and completeness of surgery did. The time to local recurrence heavily depended on the primary tumor pathological stage. Chest wall was the commonest relapse site, and the most suitable for surgical retreatment, which was related to the quality of surgery.

Abstract
BACKGROUND Hyperprolactinemia is the most common disturbance in pituitary gland secretion. Functional diversity of prolactin action is responsible for different initial clinical expressions of hyperprolactinemia. PATIENTS AND METHODS We investigated causes of hyperprolactinemia in 11 children and adolescents (6 females and 5 males), aged from 1.5 to 17.5 years. Children with primary hypothyroidism, iatrogenic hyperprolactinemia and adolescents with polycystic ovaries were excluded. RESULTS Four patients had short stature or growth deceleration, the same number were clinically obese, 2 adolescent girls had secondary amenorrhea, 1 girl had premature thelarche and gynecomastia, and hypogonadism was the indication for the endocrinologic examination of two adolescent boys. Delayed pubertal development was present in both sexes. Hyperprolactinemia was also found in the youngest girl with multiple ovarian cysts. A very high prolactin (PRL) level was documented in the PRL profile of all patients (mean 2,553.00 +/- 1,020.97 mU/l). MRI of the pituitary was indicated and revealed 4 microprolactinomas, one congenital hypophyseal cyst and one tumor of the hypothalamus. Dopamine agonist treatment was efficacious in almost all the patients. CONCLUSION Hyperprolactinemic children expressed a wide variety of initial clinical presentations. The most common were growth and puberty disorders and obesity. PRL determination should be included in investigation protocols of obese and short stature children.

Abstract
Previous studies have suggested that the multiple transplants might be equally metabolically efficient to a single regimen for human adult islets. The aim of this study was to compare immunological and metabolic parameters after each of the two regimens of human fetal islets (HFI). Group A single transplants (n = 9) had 180 +/- 20 x 1000 HFI equivalents (IEQs) implanted via a single intramuscular injection. In group B multiple transplants (n = 8) islets were implanted by three consecutive injections of 60 +/- 10 x 1000 IEQs at 7-day intervals. We analyzed the immunological parameters of CD4/CD8 T lymphocyte ratios; islet cell antibodies (ICAs) and insulin antibodies (IAs). We estimated insulin secreting capacity (ISC) as the metabolic parameter. We observed that the CD4+/CD8+ T-cell ratio increased, peaking on day 90, in similar fashion in both groups: day -1: A = 1.18 +/- 0.03 versus B = 1.19 +/- 0.04; on day 90: A = 1.79 +/- 0.09, versus B = 1.75 +/- 0.08 (P = NS) immediately before the decrease in C-peptide levels. Thereafter the ratios rapidly decreased without statistical differences. The levels of ICAs did not change. The levels of IAs, which were increased before transplant, then decreased without statistical differences between the groups. The values of ISC increased after transplant and then decreased similar to the T-cell ratio. Our results demonstrated that regimens of multiple and single HFIs did not show differences in the kinetics of the immunological response presumably mediating graft destruction. The CD4/CD8 ratio increased as the C-peptide level decreased, peaking on day 90 at the time of a decrease in C-peptide. These results may be useful for clinical studies of HFIs for type 1 diabetic patients.

We analyzed the metabolic parameters on days -1, 30, 60, 90, 120, 150, and 180 after the procedure. Among the metabolic parameters, we evaluated insulin secretion capacity-ISC (C peptide, RIA), metabolic control (HbA1c, chromatography), and insulin daily dose IDD. We found that C peptide levels increased, peaking on day 90 (A: 0.38 +/- 0.15; B: 0.34 +/- 0.19 nmol/L, P = NS) and then rapidly decreasing without differences, the HbA1c levels and IDD decreased in the same manner without differences between the groups. Our results demonstrate that multiple and single islet transplant regimens are equally efficient to temporarily restore a significant ISC with improvement of metabolic and clinical parameters. The results imply that the two regimens have an equal clinical value.

Abstract
Surgery is the initial therapy in differentiated thyroid carcinoma (DTC). The surgery is performed on organ of tumor origin and regional lymphatic basins. The aim of surgery in DTC is to eradicate all tumor foci, cure the most number of patients, reduce recurrence and mortality rate, and provide good quality of life. There is no doubt between oncologists that the surgery for thyroid carcinoma has no alternative. The extent of surgery is matter of actual controversies. It should be performed by well trained surgeons. Dissection of central and biopsy of supraclavicular and lower third of jugulo-carotid chain of neck lymph nodes is the integral part of surgery in DTC, together with total thyroidectomy. If lymph node metastases are found in jugulo-carotid chain, modified radical neck dissection, unilateral or bilateral is indicated. Dissection of mediastinal lymph nodes should be performed too in cases of involvement. The extent of primary surgery should be dictated by stage of disease and prognostic factors. The quality of surgery and incidence of complications depends prognostic factors, as well as on surgeon's skill and experience. That is why the surgeon is factor of prognosis in treatment of patients with DTC.

Abstract
At the time of fusion, membranes are packed with fusogenic proteins. Do adjacent individual proteins interact with each other in the plane of the membrane? Or does each of these proteins serve as an independent fusion machine? Here we report that the low pH-triggered transition between the initial and final conformations of a prototype fusogenic protein, influenza hemagglutinin (HA), involves a preserved interaction between individual HAs. Although the HAs of subtypes H3 and H2 show notably different degrees of activation, for both, the percentage of low pH-activated HA increased with higher surface density of HA, indicating positive cooperativity. We propose that a concerted activation of HAs, together with the resultant synchronized release of their conformational energy, is an example of a general strategy of coordination in biological design, crucial for the functioning of multiprotein fusion machines.

Abstract
Two subunits of influenza hemagglutinin (HA), HA1 and HA2, represent one of the best-characterized membrane fusion machines. While a low pH conformation of HA2 mediates the actual fusion, HA1 establishes a specific connection between the viral and cell membranes via binding to the sialic acid-containing receptors. Here we propose that HA1 may also be involved in modulating the kinetics of HA refolding. We hypothesized that binding of the HA1 subunit to its receptor restricts the major refolding of the low pH-activated HA to a fusion-competent conformation and, in the absence of fusion, to an HA-inactivated state. Dissociation of the HA1-receptor connection was considered to be a slow kinetic step. To verify this hypothesis, we first analyzed a simple kinetic scheme accounting for the stages of dissociation of the HA1/receptor bonds, inactivation and fusion, and formulated experimentally testable predictions. Second, we verified these predictions by measuring the extent of fusion between HA-expressing cells and red blood cells. Three experimental approaches based on 1) the temporal inhibition of fusion by lysophosphatidylcholine, 2) rapid dissociation of the HA1-receptor connections by neuraminidase treatment, and 3) substitution of membrane-anchored receptors by a water-soluble sialyllactose all provided support for the proposed role of the release of HA1-receptor connections. Possible biological implications of this stage in HA refolding and membrane fusion are being discussed.

Membrane fusion mediated by baculovirus gp64 involves assembly of stable gp64 trimers into multiprotein aggregates. J Cell Biol 1998; 143:1155-66.

Abstract
The baculovirus fusogenic activity depends on the low pH conformation of virally-encoded trimeric glycoprotein, gp64. We used two experimental approaches to investigate whether monomers, trimers, and/or higher order oligomers are functionally involved in gp64 fusion machine. First, dithiothreitol (DTT)- based reduction of intersubunit disulfides was found to reversibly inhibit fusion, as assayed by fluorescent probe redistribution between gp64-expressing and target cells (i.e., erythrocytes or Sf9 cells). This inhibition correlates with disappearance of gp64 trimers and appearance of dimers and monomers in SDS-PAGE. Thus, stable (i.e., with intact intersubunit disulfides) gp64 trimers, rather than independent monomers, drive fusion. Second, we established that merger of membranes is preceded by formation of large (greater than 2 MDa), short-lived gp64 complexes. These complexes were stabilized by cell-surface cross-linking and characterized by glycerol density gradient ultracentrifugation. The basic structural unit of the complexes is stable gp64 trimer. Although DTT-destabilized trimers were still capable of assuming the low pH conformation, they failed to form multimeric complexes. The fact that formation of these complexes correlated with fusion in timing, and was dependent on (a) low pH application, (b) stable gp64 trimers, and (c) cell-cell contacts, suggests that such multimeric complexes represent a fusion machine.

Abstract
The antioxidant α-tocopherol (vitamin E), applied in a basal trunk band to the green ash tree,Fraxinus pennsylvanica var.subintergerrinia, elicited an alteration of foliar feeding byMalacosoma disstria larvae (Lepidoptera: Lasiocampidae). The bioassayed effects were dependent on the dosage of elicitor, the time after elicitation, and the position in the tree. Leaves for chemical analysis were collected from trees receiving two dosages and at two intervals after elicitation. Compounds in the ethyl acetate extractables from the ash tree leaves were separated by TLC and HPLC. TLC separations showed differences in the nonhydrolyzed extractables attributable to elicitor dosage and time after elicitation. TLC-resolved differences were also evident among acid-hydrolyzed samples. HPLC-resolved profiles revealed eight peaks in the nonhydrolyzed extractables that were quantitatively negatively correlated with larval feeding preference between elicited versus control foliage on at least one of the two sampling dates. Results from this study and other investigations reported in the literature indicate that the antioxidantα-tocopherol (vitamin E) can function as an environmental-stress elicitor of alterable defensive chemistry in green ash and other plants.
