Abstract
The parakeratinized epithelium is a common and widespread type of keratinized epithelium in the oral cavity in adult birds. In contrast to orthokeratinized epithelium, which mostly covers mechanical papillae and the lingual nail, parakeratinized epithelium covers almost the entire dorsal surface of the tongue in birds. The characteristic feature of parakeratinized epithelium is the presence of nuclei in the keratinized layer. The present study aimed to investigate for the first time the micro- and ultrastructural changes of parakeratinized epithelium during embryonic development and to assess the readiness of the epithelium to serve protective functions during food transport to the esophagus. Three developmental stages were distinguished: embryonic, transformation, and pre-hatching stages. The embryonic stage lasts from the 9th to the 14th day of incubation and the epithelium is composed of undifferentiated epithelial cells. The transformation stage lasts from the 15th to the 22nd day of incubation and the epithelium undergoes transformation into stratified epithelium consisting of basal, intermediate, and superficial layers. The characteristic feature of this stage is formation of the periderm with osmophilic granules. The pre-hatching stage starts on the 23rd day, and the epithelium with a fully developed keratinized layer resembles that of the epithelium in adult animals. No periderm was observed on the epithelial surface. It was confirmed that at the time of hatching the parakeratinized epithelium is fully differentiated and ready to fulfill its function during food transport. The presence of periderm is a common feature characteristic for para- and orthokeratinized epithelium in the oral cavity of birds. However, the formation of the keratinized/cornified layer is different for these two types of keratinized epithelia.

Abstract
The study describes the sequence of ultrastructural changes of the endometrial lining epithelium, first in the primordial paramesonephric ducts, then in the differentiating uterine horns, and finally in the mature uterus. The research material comprised female fetuses of the domestic cat, aged 33-63 days post conceptionem (p.c.), and mature females. The ultrastructural observations of the developing epithelium were conducted using transmission electron microscopy (TEM) and light microscopy (LM). The results revealed two basic stages in the development of the uterine mucosal epithelium in the domestic cat: the development of the epithelium of the uterine segment of the paramesonephric ducts, lasting from day 33 to day 42 p.c., and the differentiation of this epithelium into the mucosal epithelium of the uterus, starting after day 42 p.c. and lasting until the end of the prenatal period. The epithelium of the uterine segments of the paramesonephric ducts is pseudostratified with a flat surface, all cells being characterized by the same distribution of desmosomes, ribosomes, rough endoplasmic reticulum (rER) cisternae, and mitochondria in the cytoplasm. The differentiating epithelium of the uterus after day 51 p.c. is pseudostratified with a varied height. In the epithelial cells there are increases of (i) the number and complexity of the junctional complexes, (ii) the number of invaginations of the lateral cell membranes, and (iii) the number of elongated mitochondria, and also there appear distended cisternae of the rER, lipid droplets and clusters of glycogen, which suggest increasing metabolism and secretory activity of the cells during the transformation of the epithelium.

Abstract
BACKGROUND One of the most severe traumatic brain injuries, the subdural haematoma, is related to damage and rupture of the bridging veins, generating an abnormal collection of blood between the dura mater and arachnoid mater. Current numerical models of these vessels rely on very simple geometries and material laws, limiting its accuracy and bio-fidelity. METHODS In this work, departing from an existing human head numerical model, a realistic geometry for the bridging veins was developed, devoting special attention to the finite elements type employed. A novel and adequate constitutive model including damage behavior was also successfully implemented. FINDINGS Results attest that vessel tearing onset was correctly captured, after comparison against experiments on cadavers. INTERPRETATION Doing so, the model allow to precisely predict the individual influence of kinematic parameters such as the pulse duration, linear and rotational accelerations in promoting vessel tearing.

Abstract
Osteoma is a benign, usually asymptomatic bone tumour, frequently arising in the nose and paranasal sinuses. Surgical treatment is required when the patient becomes symptomatic or presents ophthalmological or neurological complications. Although an endoscopic approach is increasingly used, depending on the size and site of the osteoma, open surgery may be preferable and remains the standard treatment. This technical note describes a case of giant osteoma of the frontal sinus that required a bicoronal approach with reconstruction by a custom-made titanium prosthesis.

Abstract
The use of natural compounds to control phytonematodes is significantly increasing, as most of the old synthetic pesticides have been banned due to their eco-hostile character. Plant secondary metabolites are now evaluated as biologically active molecules against Meloidogyne spp. but their target site in the nematode body is rarely specified. Herein, we report on the ultrastructure modifications of the Meloidogyne incognita J2 after treatment with nematicidal plant secondary metabolites, that is acetic acid, (E)-2-decenal, and 2-undecanone. The commercial nematicide fosthiazate acting on acetylcholinesterase was used as control. For this reason, scanning electron microscopy and transmission electron microscopy have been employed. The acetic acid mainly harmed the cuticle, degenerated the nuclei of pseudocoel cells, and vacuolised the cytoplasm. The (E)-2-decenal and 2-undecanone did neither harm to the cuticle nor the somatic muscles but they degenerated the pseudocoel cells. (E)-2-decenal caused malformation of somatic muscles. According to the above, the nematicidal compounds seem to enter the nematode body principally via the digestive system rather than the cuticle, since the main part of the damage is internal.

Abstract
In microbiological terms, pharmaceutical products can be divided into two groups: sterile and non-sterile. Non-sterile drugs must satisfy the appropriate microbiological purity criteria which are included in pharmacopoeial monographs. Pharmacopoeial studies are prepared specifically with a view to ensuring that the medicinal product is therapeutically effective and safe for the patient. The analysis comprised the results of microbiological purity tests performed before the products are marketed. Total of 1285 samples of non-sterile drugs manufactured by different pharmaceutical plants in Polish were taken into study. The microbiological quality of drugs was assessed in accordance with the criteria included in the European Pharmacopoeia (EP). An analysis of test results demonstrated that the percentage of non-compliant samples was 1.87%. The groups of drugs, which the most often did not satisfy EPs’ requirements, were drugs containing raw materials of natural origin (5.7%). The samples of studied drugs that did not meet the criteria contained in EP, exceed the maximum allowable microbiological count limits and contained microbes whose presence is prohibited. The most common non-compliance was the excessive levels of the maximum acceptable fungal count (n = 12) and the excessive the maximum acceptable aerobic microbial count (n = 10).

Abstract
BACKGROUND AND PURPOSE Stapes surgery for otosclerosis can be challenging when the oval window niche is narrow. We analyzed the reliability of CT to evaluate the height of the OWN and propose a quantitative criterion to distinguish normal and narrow OWNs. MATERIALS AND METHODS Fifty-six patients were scheduled for primary stapes surgery and, with available preoperative CT scans, were prospectively enrolled in the study at a tertiary care hospital. OWN height was measured on coronal CT and qualitatively evaluated during surgery. CT findings and surgical observations were matched to determine the preoperative imaging criterion of a narrow OWN. RESULTS OWN was found to be narrow during surgery in 8 of 56 patients (14%). On CT, mean OWN height measurement was 1.1 mm for the narrow group and 1.8 mm for the normal OWN surgical cases. The cutoff between normal and narrow OWN was computed at 1.3 mm by using discriminant analysis and at 1.4 mm with boxplot analysis. These CT cutoff values allowed a correct classification of "normal" and "narrow" OWN, compared with visual evaluation during surgery. CONCLUSIONS Measurements of the OWN height provide an accurate and relevant evaluation of this region before otosclerosis surgery. A width below 1.4 mm should be considered at risk for technical difficulties during the stapes footplate approach.

Abstract
Groundwater from karst aquifers is an important source of drinking water worldwide. Outbreaks of cryptosporidiosis linked to surface water and treated public water are regularly reported. Cryptosporidium oocysts are resistant to conventional drinking water disinfectants and are a major concern for the water industry. Here, we examined conditions associated with oocyst transport along a karstic hydrosystem, and the impact of intensive exploitation on Cryptosporidium oocyst contamination of the water supply. We studied a well-characterized karstic hydrosystem composed of a sinkhole, a spring and a wellbore. Thirty-six surface water and groundwater samples were analyzed for suspended particulate matter, turbidity, electrical conductivity, and Cryptosporidium and Giardia (oo)cyst concentrations. (Oo)cysts were identified and counted by means of solid-phase cytometry (ChemScan RDI(®)), a highly sensitive method. Cryptosporidium oocysts were detected in 78% of both surface water and groundwater samples, while Giardia cysts were found in respectively 22% and 8% of surface water and groundwater samples. Mean Cryptosporidium oocyst concentrations were 29, 13 and 4/100 L at the sinkhole, spring and wellbore, respectively. Cryptosporidium oocysts were transported from the sinkhole to the spring and the wellbore, with respective release rates of 45% and 14%, suggesting that oocysts are subject to storage and remobilization in karst conduits. Principal components analysis showed that Cryptosporidium oocyst concentrations depended on variations in hydrological forcing factors. All water samples collected during intensive exploitation contained oocysts. Control of Cryptosporidium oocyst contamination during intensive exploitation is therefore necessary to ensure drinking water quality.

Abstract
The leading cause of death from cancer is tumor expansion, which usually leads to dissemination and metastasis of malignant cells. Accumulating evidence suggests growing tumors contain some very rare primitive cells that are mobile and thus endowed with metastatic potential. If these cells survive radio/chemotherapy, they are responsible for tumor re-growth after treatment. In this review, we discuss the origin of these cells, which: 1) are true cancer stem cells (CSCs) that initiate tumor growth and are subsequently responsible for metastatic dissemination; or 2) are derived from transformed tumor cells by the epithelial mesenchymal transition phenomenon. We also address major molecular mechanisms involved in trafficking of these cells during metastasis, paying special attention to the underappreciated side effects of radio/chemotherapy that may induce pro-metastatic environments in various organs. Overall, we envision that the process of pathological metastasis of cancer cells reflects a physiological property of normal SCs for their ability to migrate, as seen during embryogenesis. Finally, we discovered highly migratory, very small embryonic-like SCs that are deposited during development in adult tissues. As we hypothesize, these cells could: 1) give rise to some primitive types of tumors; and 2) may have a direct role in cancer expansion by being involved in tumor angiogenesis and formation of tumor stroma.

Abstract
We have previously shown that platelet factor 4 (PF4), a platelet-specific CXC chemokine, can directly and specifically inhibit human megakaryocyte colony formation. We therefore hypothesized that PF4 might function as a negative autocrine regulator of megakaryocytopoiesis. Herein we present additional studies characterizing the inhibitory effect of CXC chemokines on human megakaryocyte development. We first corroborated our initial studies by showing that recombinant human (rH) PF4, like the native protein, inhibited megakaryocytopoiesis. We then examined the inhibitory properties of other CXC family members. Neutrophil activating peptide-2 (NAP-2), a naturally occurring N-terminally cleaved beta TG peptide, was found to inhibit megakaryocytopoiesis with two to three orders of magnitude greater potency than PF4. Structure function studies showed that an N-terminal mutation, which eliminated NAP-2's neutrophil activating properties (NAP-2E2-->A), also abrogated its ability to inhibit megakaryocyte development. Further investigations of this type demonstrated that a chimeric PF4 protein (AELR/PF4) in which PF4's N-terminus was replaced with the first four amino acids of NAP-2 was also a potent inhibitor of megakaryocytopoiesis. Interleukin (IL)-8, another CXC chemokine, and three CC chemokines (macrophage inhibitory protein-1 alpha [MIP-1 alpha], MIP-1 beta, and C10) also specifically inhibited megakaryocyte colony formation at NAP-2 equivalent doses. CXC and CC chemokine inhibition was additive suggesting that the effects might be mediated through a common pathway. The inhibitory effects of NAP-2 and MIP-1 alpha could not be overcome by adding physiologically relevant amounts of recombinant human megakaryocyte growth and development factor (MGDR) (50 ng/mL) to the cultures. Using Northern blot and reverse transcriptase-polymerase chain reaction (RT-PCR) based analyses, we documented mRNA expression of IL-8 receptor isoforms alpha and beta in total platelet RNA and in normal human megakaryocytes, respectively. Based on these results, we hypothesize that chemokines play a physiologic role in regulating megakaryocytopoiesis. Because chemokines are elaborated by ancillary marrow cells, both autocrine and paracrine growth control is suggested, the effects of which might be exerted, in part, through alpha and beta IL-8 receptors.

Abstract
Synthetic oligodeoxynucleotides (antisenses) complementary to bcr/abl breakpoint junction transcript on Philadelphia chromosome, or c-myb protooncogene inhibit partially the proliferation of Philadelphia positive leukemic cells (antisenses against bcr/abl and c-myb) and other tumor cells (antisenses against c-myb). This phenomenon is accompanied by specific downregulation of mRNA level of the particular gene. To develop a more effective procedure of tumor treatment the combination of low dose of cytostatic and bcr/abl or c-myb antisenses against Philadelphia chromosome positive cell line BV173, and the combination of anti-tumor cytotoxic T lymphocytes (CTL) and c-myb antisenses against melanoma cell line MM-28, were tested in vitro. Our results indicate that the combinations of conventional chemotherapeutic agent and antisense against bcr/abl or c-myb or tumor specific CTL and antisense against c-myb, are highly effective in killing of tumor cells and sparing normal cells. This creates the possibility to develop a more selective and effective treatment of neoplasia.

Abstract
There is evidence to suggest that the p120 GAP (GAP), originally described as an inhibitor of p21ras, may also serve as a downstream effector of ras-regulated signal transduction. To determine whether GAP expression is required for the growth of human normal and leukemic hematopoietic cells, we used GAP antisense oligodeoxynucleotides to inhibit it and analyzed the effects of this inhibition on the colony-forming ability of nonadherent, T lymphocyte-depleted mononuclear cells and of highly purified progenitors (CD34+ MNC) obtained from the bone marrow and peripheral blood of healthy volunteers or chronic myeloid leukemia (CML, bcr-abl-positive) patients. The acute myelogenous leukemia cell line MO7, the Philadelphia BV173 cell line, and the acute promyelocytic leukemia NB4 and HL-60 cell lines were similarly examined. GAP antisense treatment inhibited colony formation from normal myelo-, erythro-, and megakaryopoietic progenitor cells as well as from CML progenitor cells. Proliferation of MO7 (growth factor-dependent) and BV173 (bcr-abl-dependent) cells, but not that of NB4 and HL-60 (growth factor-independent) cells, was also inhibited, even though a specific downregulation of GAP was observed in each cell line, as analyzed by either or both mRNA and protein expression. Stimulation of MO7 cells with hematopoietic growth factors increased the expression of GAP as well as the levels of active GTP-bound p21ras. Stimulation of GAP expression was inhibited upon GAP antisense treatment. These data indicate that p120 GAP is involved in human normal and leukemic hemopoiesis and strongly suggest that GAP is not only a p21ras inhibitor (signal terminator), but also a positive signal transducer.

Abstract
The murine white (W) spotting locus is the site of the c-kit gene and encodes a tyrosine kinase receptor while the complementary Steel (Sl) locus encodes its ligand. Mutations at either locus have profound effects on hematopoiesis, particularly erythroid and mast cell proliferation. We added c-kit antisense oligonucleotides to long-term suspension cultures of enriched human umbilical cord progenitor cells. This resulted in the suppression of c-kit gene expression and the preferential suppression of the generation of erythroid burst-forming cells (BFU-E) which extended over the life of the culture (3 weeks). The results provide an in vitro model of the "W phenotype" in human hematopoiesis and confirm the importance of c-kit gene function in early erythropoiesis. Because the generation of BFU-E was suppressed even after c-kit gene expression had recovered, this gene product may be critical to the erythroid commitment process.

Abstract
In this report we investigate the role of homeobox genes of the Antennapedia class in adult erythropoiesis, the process by which erythrocytes are formed in the bone marrow. We initially identified Hox genes expressed in mouse erythroleukemia cells by a PCR technique using degenerate primers capable of detecting most of the known genes in Hox clusters 1-4. Four different transcripts, Hox-3.3, -3.5, -3.6, and -4.3 were identified. An antisense oligonucleotide directed against HOX3C (human homologue of Hox-3.3) was used to study the effect of the colony formation by human erythroid progenitor cells. The oligonucleotide inhibited the formation of colony-forming unit erythroid-derived colonies but did not affect the size or degree of hemoglobinization. The more primitive erythroid burst-forming unit colonies or myeloid colonies were not affected. These results show that Hox-3.3 is involved in an early step in the proliferation of the erythroid colony-forming unit subset of progenitor cells.

Abstract
72 patients of the psychiatric department of the general hospital in Berlin Neukölln were interviewed unselectedly to the subjects of lodging and income with the help of a semistructured interview. Only 16 (22%) patients still had a job, 17 (24%) were without job and 31 (43%) were on pension. 10 patients (14%) were homeless, 12 patients (17%) lived in insufficient conditions of housing. Only 11 patients (15%) earned their own wage/salary. All together 25 patients (36%) were in some way dependent on support by social security. Half of the patients had a regular income of less than DM 1000.--a month. The everyday dealing with the problem of poverty on the ward is pointed out and discussed. Obviously this theme is not integrated enough in the therapeutic process. This subject can not only be delegated to the responsibility of the social worker.

Abstract
The c-myb protooncogene is preferentially expressed in hematopoietic cells, and its encoded protein, Myb, is required for hematopoietic cell proliferation. To analyze the relative Myb dependence of normal and leukemic human hematopoietic progenitor cells, normal bone marrow cells, several types of leukemic blast cells, and 1:1 mixtures of normal and leukemic cells were cultured in the presence of c-myb sense or antisense oligodeoxynucleotides; cell viability and cloning efficiency were then assessed. c-myb sense oligomers had negligible effects on normal and leukemic cells. In contrast, c-myb antisense oligomers strongly inhibited or completely abolished clonogenic growth of a T-cell leukemia line, 78% (18 of 23) of primary acute myelogenous leukemia cases examined, and 4 of 5 primary chronic myelogenous leukemia (CML) cases in blast crisis. In three of the latter patients, polymerase chain reaction analysis of a 1:1 mixture of c-myb antisense-treated normal and CML cells revealed a complete absence of bcr-abl expression, suggesting that the CML clonogenic units had been completely eliminated from the cultures. At antisense doses that inhibited leukemic cell growth, normal hematopoietic progenitor cells survived. Thus, normal and leukemic hematopoietic cells show differential sensitivity to the toxic effects of c-myb antisense DNA. Perturbation of c-myb function with antisense oligodeoxynucleotides might eventually form the basis for a molecular approach to leukemia therapy, perhaps most immediately as ex vivo bone marrow purging agents.

Abstract
We have tested the immunologic status and hematologic parameters of mice 2 months (short-term survivors) or 18 months (long-term survivors) after lethal total body irradiation and syngeneic bone marrow transplantation (SBMT), and of normal mice of corresponding age. Long-term SBMT survivors showed significantly lowered bone marrow and spleen cellularities, decreased numbers of CFU-S in hemopoietic organs and severe impairment in the formation of CFU-F colonies compared with short-term SBMT survivors and normal mice. The peripheral blood parameters (hematocrit, erythrocytes, reticulocytes, platelets, white blood cells and granulocyte counts), however, remained unaltered. In long-term SBMT survivors we also observed a relative increase of Lyt-2+ lymphocytes (CD8+, cytotoxic/suppressor) and Mac-1+ cells among splenocytes. At the same time the L3T4+/Lyt-2+ ratio (CD4+/CD8+) was decreased. Relative contents of Ig+, Thy-1+ and L3T4+ cells were unchanged. The ability of splenocytes to generate IL-2R+ cells after in vitro stimulation with concanavalin A was greatly diminished. In summary, the immunohematopoietic status after initial normalization is again impaired in long-term SBMT survivors.

Abstract
The immunohematopoietic reconstitution of mice lethally irradiated (TBI) and reconstituted with syngeneic bone marrow cells untreated or treated with mafosfamide (ASTA Z 7654) [TBI + SBMT or TBI + SBMT-Maf mice, respectively] was examined. The number of CFU-S was greatly reduced in TBI + SBMT-Maf mice compared with those in TBI + SBMT mice. The recovery of blood parameters (hematocrit, reticulocytes, erythrocytes, white blood cells, granulocytes, platelets) and of bone marrow and spleen cells, but not of peritoneal exudate cells, was slightly delayed in TBI + SBMT-Maf mice compared with those in TBI + SBMT mice. The time for immune system regeneration was, however, considerably longer in TBI + SBMT-Maf than in TBI + SBMT mice, as measured by the incidence of Ig+, Thy-1.2+, L3T4+, Lyt-2+, and IL-2R+ cells in the spleens. The appearance of Mac-1+ and asialo-GM 1+ cells was only slightly prolonged or unchanged, respectively.
