Abstract
A major challenge for clinical management of melanoma is the prevention and treatment of metastatic disease. Drug discovery efforts over the last 10 years have resulted in several drugs that improve the prognosis of metastatic melanoma; however, most patients develop early resistance to these treatments. We designed and synthesized, through a concise synthetic strategy, a series of hybrid olefin-pyridinone compounds that consist of structural motifs from tamoxifen and ilicicolin H. These compounds were tested against a human melanoma cell line and patient-derived melanoma cells that had metastasized to the brain. Three compounds 7 b, 7 c, and 7 g demonstrated promising activity (IC50=0.4-4.3 μM). Cell cycle analysis demonstrated that 7 b and 7 c induce cell cycle arrest predominantly in the G1 phase. Both 7 b and 7c significantly inhibited migration of A375 melanoma cells; greater effects were demonstrated by 7 b. Molecular modelling analysis provides insight into a plausible mechanism of action.

Abstract
The anterior pituitary controls key biological processes, including growth, metabolism, reproduction, and stress responses through distinct cell types that each secrete specific hormones. The anterior pituitary cells show a remarkable level of cell type plasticity that mediates the shifts in hormone-producing cell populations that are required to meet organismal needs. The molecular mechanisms underlying pituitary cell plasticity are not well understood. Recent work has implicated the pituitary stem cell populations and specifically, the mRNA binding proteins of the Musashi family in control of pituitary cell type identity. In this study we have identified the target mRNAs that mediate Musashi function in the adult mouse pituitary and demonstrate the requirement for Musashi function in vivo. Using Musashi RNA immunoprecipitation, we identify a cohort of 1184 mRNAs that show specific Musashi binding. Identified Musashi targets include the Gnrhr mRNA, which encodes the gonadotropin-releasing hormone receptor (GnRHR), and the Fshb mRNA, encoding follicle-stimulating hormone (FSH). Reporter assays reveal that Musashi functions to exert repression of translation of the Fshb mRNA, in addition to the previously observed repression of the Gnrhr mRNA. Importantly, mice engineered to lack Musashi in gonadotropes demonstrate a failure to repress translation of the endogenous Gnrhr and Fshb mRNAs during the estrous cycle and display a significant heterogeneity in litter sizes. The range of identified target mRNAs suggests that, in addition to these key gonadotrope proteins, Musashi may exert broad regulatory control over the pituitary proteome in a cell type-specific manner.

Abstract
Melanoma is one of the most aggressive forms of skin cancer and is characterized by high metastatic potential. Despite improvements in early diagnosis and treatment, the mortality rate among metastatic melanoma patients continues to represent a significant clinical challenge. Therefore, it is imperative that we search for new forms of treatment. Trametes versicolor is a mushroom commonly used in Chinese traditional medicine due to its numerous beneficial properties. In the present work, we demonstrate T. versicolor fruiting body and mycelium ethanol extracts exhibit potent cytotoxic activity towards A375 (IC50 = 663.3 and 114.5 µg/mL respectively) and SK-MEL-5 (IC50 = 358.4 and 88.6 µg/mL respectively) human melanoma cell lines. Further studies revealed that T. versicolor mycelium extract induced apoptotic cell death and poly (ADP-ribose) polymerase cleavage, upregulated the expression of autophagy-associated marker LC3-II, increased the presentation of major histocompatibility complex II and expression of programmed death-ligand receptor, and inhibited cell migration in SK-MEL-5 cells. Therefore, our present findings highlight the therapeutic potential of T. versicolor mycelium extract for the treatment of melanoma and merit further study.

Abstract
Abstract
The pituitary gland controls responses to changing physiological requirements during growth, pregnancy, puberty, and stress. Synthesis and secretion of appropriate pituitary hormones in response to changing organismal demands is mediated through a remarkable capacity for cellular plasticity of the distinct hormone-producing cells. The mechanisms governing pituitary cellular plasticity are not fully understood. We hypothesize that plasticity in the adult tissue is mediated through similar mechanisms to those that occur during embryonic and postnatal pituitary development. The Prophet of Pit1(Prop1), a paired-like homeodomain transcription factor, is the earliest pituitary-specific transcription factor and is highly expressed in pituitary progenitor cells where it controls lineage commitment to the distinct hormone-producing cell types. Our recent work has identified post-transcriptional regulation of pituitary gene expression in the adult tissue via the stem cell determinant, mRNA binding protein, Musashi. The full-length mouse Prop1 (mProp1) mRNA 3' untranslated region (UTR) contains 24 consensus binding elements for Musashi (MBEs) and demonstrates Musashi1-dependent translational activation in vitro. Specifically, the terminal mProp1 3' UTR MBE directs 40% of Musashi1-mediated translation activation, and mutational disruption of this terminal MBE abolishes all Musashi1-dependent translational activation. Immunoprecipitation of Musashi-mRNA complexes from adult mouse pituitaries confirmed Musashi1-mProp1 mRNA association in adult tissue. The gene sequence data for the human Prop1 (hPROP1) mRNA 3' UTR is incomplete in the Ensembl and RefSeq databases. Using published RNA sequencing datasets, we identified an expressed full-length hPROP1 mRNA 3' UTR of 6996 nucleotides with 54 predicted consensus MBEs, suggesting that the human PROP1 mRNA, like the murine Prop1 mRNA, may be subject to Musashi-dependent translational control. Our findings are consistent with the hypothesis that the Musashi protein exerts evolutionarily conserved control of Prop1 mRNA translation to facilitate plasticity of anterior pituitary function.

Abstract
The anterior pituitary controls growth, metabolism, reproduction and stress responses through the synthesis and secretion of specific hormones. Distinct cell lineages within the anterior pituitary generate specific hormones. Interestingly, the anterior pituitary exhibits a high level of adult cell plasticity that allows committed hormone-producing cells to alter their cell fate and produce different hormones to meet altered organismal demands. The molecular mechanisms underlying this adult cell plasticity have not been fully characterized. Our recent work has implicated the stem cell determinant and sequence-specific mRNA binding protein, Musashi, as a regulator of pituitary cell plasticity. The mechanisms by which Musashi controls pituitary cell plasticity are unknown. In this study, we have sought to identify the mRNA regulatory targets of Musashi in the adult mouse pituitary. Through the use of Musashi-RNA-immunoprecipitation we report a cohort of 1192 pituitary mRNAs that specifically interact with Musashi. mRNAs specific to each of the hormone-producing cell lineages were identified, as well as mRNAs specific to immature stem and progenitor cell lineages. The biological pathways encoded by the Musashi-enriched mRNAs include cell adhesion, cellular homeostasis, unfolded protein responses, protein trafficking, endocrine processes and female pregnancy. Functional analysis of validated mRNAs reveals both activating and inhibitory control of mRNA translation by Musashi. Together, our findings indicate a broad and complex role for Musashi in the post-transcriptional regulation of adult pituitary function.

Abstract
Glioblastoma (GBM) remains the most frequently diagnosed primary malignant brain cancer in adults. Despite recent progress in understanding the biology of GBM, the clinical outcome for patients remains poor, with a median survival of approximately one year after diagnosis. One factor contributing to failure in clinical trials is the fact that traditional models used in GBM drug discovery poorly recapitulate patient tumors. Previous studies have shown that monensin (MON) analogs, namely esters and amides on C-26 were potent towards various types of cancer cell lines. In the present study we have investigated the activity of these molecules in GBM organoids, as well as in a host:tumor organoid model. Using a mini-ring cell viability assay we have identified seven analogs (IC50 = 91.5 ± 54.4–291.7 ± 68.8 nM) more potent than parent MON (IC50 = 612.6 ± 184.4 nM). Five of these compounds induced substantial DNA fragmentation in GBM organoids, suggestive of apoptotic cell death. The most active analog, compound 1, significantly reduced GBM cell migration, induced PARP degradation, diminished phosphorylation of STAT3, Akt and GSK3β, increased ɣH2AX signaling and upregulated expression of the autophagy associated marker LC3-II. To investigate the activity of MON and compound 1 in a tumor microenvironment, we developed human cerebral organoids (COs) from human induced pluripotent stem cells (iPSCs). The COs showed features of early developing brain such as multiple neural rosettes with a proliferative zone of neural stem cells (Nestin+), neurons (TUJ1 +), primitive ventricular system (SOX2 +/Ki67 +), intermediate zone (TBR2 +) and cortical plate (MAP2 +). In order to generate host:tumor organoids, we co-cultured RFP-labeled U87MG cells with fully formed COs. Compound 1 and MON reduced U87MG tumor size in the COs after four days of treatment and induced a significant reduction of PARP expression. These findings highlight the therapeutic potential of MON analogs towards GBM and support the application of organoid models in anti-cancer drug discovery.

Abstract
Microtubule targeting agents (MTAs) are widely used cancer chemotherapeutics which conventionally exert their effects during mitosis, leading to mitotic or postmitotic death. However, accumulating evidence suggests that MTAs can also generate death signals during interphase, which may represent a key mechanism in the clinical setting. We reported previously that vincristine and other microtubule destabilizers induce death not only in M phase but also in G1 phase in primary acute lymphoblastic leukemia cells. Here, we sought to investigate and compare the pathways responsible for phase-specific cell death. Primary acute lymphoblastic leukemia cells were subjected to centrifugal elutriation, and cell populations enriched in G1 phase (97%) or G2/M phases (80%) were obtained and treated with vincristine. We found death of M phase cells was associated with established features of mitochondrial-mediated apoptosis, including Bax activation, loss of mitochondrial transmembrane potential, caspase-3 activation, and nucleosomal DNA fragmentation. In contrast, death of G1 phase cells was not associated with pronounced Bax or caspase-3 activation but was associated with loss of mitochondrial transmembrane potential, parylation, nuclear translocation of apoptosis-inducing factor and endonuclease G, and supra-nucleosomal DNA fragmentation, which was enhanced by inhibition of autophagy. The results indicate that microtubule depolymerization induces distinct cell death pathways depending on during which phase of the cell cycle microtubule perturbation occurs. The observation that a specific type of drug can enter a single cell type and induce two different modes of death is novel and intriguing. These findings provide a basis for advancing knowledge of clinical mechanisms of MTAs.

Abstract
Abstract
Background
In dementia research, supporting personhood is seen as a corner stone of person-centred care. However, little is understood about how personhood is conceptualised in the context of the home and communities that people living with dementia reside within, and how place may constitute a key dimension of, or a determining factor of someone’s sense of self. This study seeks to explore these relationships by examining the intersection between place and personhood through the lens of Rowles (1983) work on place and personal identity in old age.
Methods
Qualitative secondary analysis of datasets from two separate studies was conducted. The first study examined the perspectives of people living with dementia on place across the life course, while the second study examined the perspectives of people living with dementia on personhood in formal care. In total, 15 interviews with people with dementia were analysed using theoretical framework analysis.
Results
Participants reflected on the meaning of place, and its iterative relationship with personhood across the life course. They used the residential life course, to convey and narrate their life story, locating themselves and major events in time and place. Participants also spoke about the impact of the physical environment on their sense of personhood, conceptualising personhood in relation to attachment to the physical landscape, location and their own homes. Finally, participants referred to the close link between place, relationships, and community. In particular, how important feelings of community and belonging to place are to their sense of personhood.
Conclusion
This research shows the role of place in interpreting understandings of personhood from the perspectives of people living with dementia. This is critical for understanding the nature and orientation of community-based interventions, and designing supports and services which appropriately harness place-based relationships of people living with dementia.

Abstract
AIMS Characterizing cannabinoid receptors (CBRs) expressed in Ewing sarcoma (EWS) cell lines as potential targets for anti-cancer drug development. MAIN METHODS CBR affinity and function were examined by competitive binding and G-protein activation, respectively. Cannabinoid-mediated cytotoxicity and cell viability were evaluated by LDH, and trypan blue assays, respectively. KEY FINDINGS qRT-PCR detected CB1 (CB1R) and CB2 receptor (CB2R) mRNA in TC-71 cells. However, binding screens revealed that CBRs expressed exhibit atypical properties relative to canonical receptors, because specific binding in TC-71 could only be demonstrated by the established non-selective CB1/CB2R radioligand [3H]WIN-55,212-2, but not CB1/CB2R radioligand [3H]CP-55,940. Homologous receptor binding demonstrated that [3H]WIN-55,212-2 binds to a single site with nanomolar affinity, expressed at high density. Further support for non-canonical CBRs expression is provided by subsequent binding screens, revealing that only 9 out of 28 well-characterized cannabinoids with high affinity for canonical CB1 and/or CB2Rs were able to displace [3H]WIN-55,212-2, whereas two ligands enhanced [3H]WIN-55,212-2 binding. Five cannabinoids producing the greatest [3H]WIN-55,212-2 displacement exhibited high nanomolar affinity (Ki) for expressed receptors. G-protein modulation and adenylyl cyclase assays further indicate that these CBRs exhibit distinct signaling/functional profiles compared to canonical CBRs. Importantly, cannabinoids with the highest affinity for non-canonical CBRs reduced TC-71 viability and induced cytotoxicity in a time-dependent manner. Studies in a second EWS cell line (A-673) showed similar atypical binding properties of expressed CBRs, and cannabinoid treatment produced cytotoxicity. SIGNIFICANCE Cannabinoids induce cytotoxicity in EWS cell lines via non-canonical CBRs, which might be a potential therapeutic target to treat EWS.

Abstract
Microtubule targeting agents (MTAs) have been used for the treatment of cancer for many decades and are among the most successful chemotherapeutic agents. However, their application and effectiveness are limited because of toxicity and resistance as well as a lack of knowledge of molecular mechanisms downstream of microtubule inhibition. Insights into key pathways that link microtubule disruption to cell death is critical for optimal use of these drugs, for defining biomarkers useful in patient stratification, and for informed design of drug combinations. Although MTAs characteristically induce death in mitosis, microtubule destabilizing agents such as vincristine also induce death directly in G1 phase in primary acute lymphoblastic leukemia (ALL) cells. Because many signaling pathways regulating cell survival and death involve changes in protein expression and phosphorylation, we undertook a comprehensive quantitative proteomic study of G1 phase ALL cells treated with vincristine. The results revealed distinct alterations associated with c-Jun N-terminal kinase signaling, anti-proliferative signaling, the DNA damage response, and cytoskeletal remodeling. Signals specifically associated with cell death were identified by pre-treatment with the CDK4/6 inhibitor palbociclib, which caused G1 arrest and precluded death induction. These results provide insights into signaling mechanisms regulating cellular responses to microtubule inhibition and provide a foundation for a better understanding of the clinical mechanisms of MTAs and for the design of novel drug combinations. The mass spectrometry proteomics data have been deposited to the PRIDE Archive (http://www.ebi.ac.uk/pride/archive/) via the PRIDE partner repository with the data set identifier PXD027190 and 10.6019/PXD027190.

Abstract
Breast cancer remains one of the leading cancers among women. Cancer stem cells (CSCs) are tumor-initiating cells which drive progression, metastasis, and reoccurrence of the disease. CSCs are resistant to conventional chemo- and radio-therapies and their ability to survive such treatment enables tumor reestablishment. Metastasis is the main cause of mortality in women with breast cancer, thus advances in treatment will depend on therapeutic strategies targeting CSCs. Salinomycin (SAL) is a naturally occurring polyether ionophore antibiotic known for its anticancer activity towards several types of tumor cells. In the present work, a library of 17 C1-single and C1/C20-double modified SAL analogs was screened to identify compounds with improved activity against breast CSCs. Six single- and two double-modified analogs were more potent (IC50 range of 1.1 ± 0.1-1.4 ± 0.2 µM) toward the breast cancer cell line MDA-MB-231 compared to SAL (IC50 of 4.9 ± 1.6 µM). Double-modified compound 17 was found to be more efficacious than SAL against the majority of cancer cell lines in the NCI-60 Human Tumor Cell Line Panel. Compound 17 was more potent than SAL in inhibiting cell migration and cell renewal properties of MDA-MB-231 cells, as well as inducing selective loss of the CD44+/CD24/low stem-cell-like subpopulation in both monolayer (2D) and organoid (3D) culture. The present findings highlight the therapeutic potential of SAL analogs towards breast CSCs and identify select compounds that merit further study and clinical development.

Abstract
Paclitaxel is widely used in the treatment of breast, ovarian, lung, and other cancers. Its primary mechanism is to prevent microtubule depolymerization causing loss of dynamic instability crucial for normal microtubule function leading to mitotic arrest. Prolonged mitotic arrest results in cell death as a secondary response. The effects of paclitaxel are typically studied in cell lines which precludes assessment of the possible influence of tumor-associated cells. We therefore examined paclitaxel action ex vivo in fresh explant cultures of human breast tumors. Surprisingly, we found that paclitaxel failed to induce tumor cell death in explant culture, in contrast to several other cytotoxic agents including salinomycin and vincristine. The lack of effect was not due to defective drug uptake, and furthermore, analysis of H&E stained tumor slices indicated that paclitaxel treatment caused defective (granular) mitosis and chromosomal condensation in 5-10% of tumor cells after 72 h. These results suggest that while paclitaxel was able to penetrate into the tumor slice and disrupt mitosis in cycling tumor cells, any ensuing cell death likely occurred beyond the useful lifetime of the tumor slices. We conclude that explant culture systems may be inappropriate for the study of cytotoxic drugs where a delay exists between the drug's primary and secondary modes of action.

Abstract
Colchicine (COL) shows strong anticancer activity but due to its toxicity towards normal cells its wider application is limited. To address this issue, a library of 17 novel COL derivatives, namely N-carbamates of N-deacetyl-4-(bromo/chloro/iodo)thiocolchicine, has been tested against two types of primary cancer cells. These included acute lymphoblastic leukemia (ALL) and human breast cancer (BC) derived from two different tumor subtypes, ER+ invasive ductal carcinoma grade III (IDCG3) and metastatic carcinoma (MC). Four novel COL derivatives showed higher anti-proliferative activity than COL (IC50 = 8.6 nM) towards primary ALL cells in cell viability assays (IC50 range of 1.1-6.4 nM), and several were more potent towards primary IDCG3 (IC50 range of 0.1 to 10.3 nM) or MC (IC50 range of 2.3-9.1 nM) compared to COL (IC50 of 11.1 and 11.7 nM, respectively). In addition, several derivatives were selectively active toward primary breast cancer cells compared to normal breast epithelial cells. The most promising derivatives were subsequently tested against the NCI panel of 60 human cancer cell lines and seven derivatives were more potent than COL against leukemia, non-small-cell lung, colon, CNS and prostate cancers. Finally, COL and two of the most active derivatives were shown to be effective in killing BC cells when tested ex vivo using fresh human breast tumor explants. The present findings indicate that the select COL derivatives constitute promising lead compounds targeting specific types of cancer.

Abstract
Colchicine belongs to a large group of microtubule polymerization inhibitors. Although the anti-cancer activity of colchicine and its derivatives has been established, none of them has found commercial application in cancer treatment due to side effects. Therefore, we designed and synthesized a series of six triple-modified 4-chlorothiocolchicine analogues with amide moieties and one urea derivative. These novel derivatives were tested against several different cancer cell lines (A549, MCF-7, LoVo, LoVo/DX) and primary acute lymphoblastic leukemia (ALL) cells and they showed activity in the nanomolar range. The obtained IC50 values for novel derivatives were lower than those obtained for unmodified colchicine and common anticancer drugs such as doxorubicin and cisplatin. Further studies of colchicine and selected analogues were undertaken to indicate that they induced apoptotic cell death in ALL-5 cells. We also performed in silico studies to predict binding modes of the 4-chlorothiocolchicine derivatives to different β tubulin isotypes. The results indicate that select triple-modified 4-chlorothiocolchicine derivatives represent highly promising novel cancer chemotherapeutics.

Abstract
The polyether ionophore salinomycin (SAL) has captured much interest because of its potent activity against cancer cells and cancer stem cells. Our previous studies have indicated that C1/C20 double-modification of SAL is a useful strategy to generate diverse agents with promising biological activity profiles. Thus, herein we describe the synthesis of a new class of SAL analogues that combine key modifications at the C1 and C20 positions. The activity of the obtained SAL derivatives was evaluated using primary acute lymphoblastic leukemia, human breast adenocarcinoma and normal mammary epithelial cells. One single- [N,N-dipropyl amide of salinomycin (5 a)] and two novel double-modified analogues [N,N-dipropyl amide of C20-oxosalinomycin (5 b) and piperazine amide of C20-oxosalinomycin (13 b)] were found to be more potent toward the MDA-MB-231 cell line than SAL or its C20-oxo analogue 2. When select analogues were tested against the NCI-60 human tumor cell line panel, 4 a [N,N-diethyl amide of salinomycin] showed particular activity toward the ovarian cancer cell line SK-OV-3. Additionally, both SAL and 2 were found to be potent ex vivo against human ER/PR+ , Her2- invasive mammary carcinoma, with 2 showing minimal toxicity toward normal epithelial cells. The present findings highlight the therapeutic potential of SAL derivatives for select targeting of different cancer types.

Abstract
Colchicine is the major alkaloid isolated from the plant Colchicum autumnale, which shows strong therapeutic effects towards different types of cancer. However, due to the toxicity of colchicine towards normal cells its application is limited. To address this issue we synthesized a series of seven triple-modified 4-bromothiocolchicine analogues with amide moieties. These novel derivatives were active in the nanomolar range against several different cancer cell lines and primary acute lymphoblastic leukemia cells, specifically compounds: 5-9 against primary ALL-5 (IC50 = 5.3-14 nM), 5, 7-9 against A549 (IC50 = 10 nM), 5, 7-9 against MCF-7 (IC50 = 11 nM), 5-9 against LoVo (IC50 = 7-12 nM), and 5, 7-9 against LoVo/DX (IC50 = 48-87 nM). These IC50 values were lower than those obtained for unmodified colchicine and common anticancer drugs such as doxorubicin and cisplatin. Further studies revealed that colchicine and selected analogues induced characteristics of apoptotic cell death but manifested their effects in different phases of the cell cycle in MCF-7 versus ALL-5 cells. Specifically, while colchicine and the studied derivatives arrested MCF-7 cells in mitosis, very little mitotically arrested ALL-5 cells were observed, suggesting effects were manifest instead in interphase. We also developed an in silico model of the mode of binding of these compounds to their primary target, β-tubulin. We conducted a correlation analysis (linear regression) between the calculated binding energies of colchicine derivatives and their anti-proliferative activity, and determined that the obtained correlation coefficients strongly depend on the type of cells used.

Abstract
The aim of the study was to review recent findings on the use of POM supplements in athletes of various disciplines and physically active participants. Eleven articles published between 2010 and 2018 were included, where the total number of investigated subjects was 176. Male participants constituted the majority of the group (n = 155), as compared to females (n = 21). 45% of research described was conducted on athletes, whereas the remaining studies were based on highly active participants. Randomised, crossover, double-blind study designs constituted the majority of the experimental designs used. POM supplementation varied in terms of form (pills/juice), dosage (50 ml-500 ml) and time of intervention (7 days-2 months) between studies. Among the reviewed articles, POM supplementation had an effect on the improvement of the following: whole body strength; feeling of vitality; acute and delayed muscle fatigue and soreness; increase in vessel diameter; blood flow and serum level of TAC; reduction in the rate of increase for HR, SBP, CK and LDH; support in the recovery of post-training CK, LDH, CRP and ASAT to their baseline levels; reduction of MMP2, MMP9, hsCRP and MDA; and increased activity of antioxidant enzymes (glutathione peroxidase and superoxide dismutase). In the majority of reviewed articles POM supplementation had a positive effect on a variety of parameters studied and the authors recommended it as a supplement for athletes and physically active bodies.

Abstract
Phyllodes tumors of the breast (PTB) are uncommon stromal-epithelial neoplasms, with the main recommended treatment being surgical removal. However, even with adequate resection, the risk of recurrence in the malignant form remains as high as 40%, and there is no recognized consensus on the most effective drugs for PTB. In the present study, an ex vivo model of malignant phyllodes and derived primary cell cultures were used to evaluate the effectiveness of a panel of different drugs, including the Bcl-2/Bcl-xL inhibitor ABT-263, salinomycin (SAL), doxorubicin (DOX), paclitaxel (TAX), vincristine (VCR), colchicine (COL) and cisplatin (CIS). ABT-263, SAL and DOX were highly effective towards phyllodes spindle cells when assessed in the ex vivo model, contributing to ~98% tumor cell death. Furthermore, ABT-263 was highly selective for tumor cells in this system, and exhibited little toxic effect on adjacent normal epithelial cells. Furthermore, consistent with findings in the ex vivo model, ABT-263 was significantly less toxic towards MCF 10A non-tumorigenic breast epithelial cells compared with SAL and DOX. A conditional reprogramming strategy was subsequently used, involving Rho kinase inhibition, to successfully generate primary phyllodes tumor cells that could be cultured for several passages. The primary cells were sensitive to DOX with an IC50 of 0.40±0.07 µM in a standard viability assay and the preliminary results were obtained indicating sensitivity to ABT-263 and SAL. The present study demonstrated the feasibility of using explants and primary cells for drug discovery, selectively targeting PTB cells.

Abstract
Background The aim of this study was to analyse the effect of pomegranate juice (POM) supplementation on the levels of selected pro-inflammatory cytokines, hepcidin and markers of iron metabolism in well-trained rowers. Method The double-blind placebo-controlled study included 19 members of the Polish Rowing Team. The athletes were randomised into the supplemented group (n = 10), receiving 50 ml of standardised POM daily for two months, or the placebo group (n = 9). The subjects performed a 2000 m test on the rowing ergometer at the start of the project (baseline) and end of follow-up period. Blood samples from the antecubital vein were obtained three times during each trial: prior to the exercise, one minute after the test, and following a 24 h recovery. Results The study documented the beneficial effect of supplementation with pomegranate fruit juice on TAC (P < 0.002). During the resting period, TAC level in the supplemented group was significantly higher than in the placebo group (x ± SD, 2.49 ± 0.39 vs. 1.88 ± 0.45, P < 0.05). The ergometric test conducted at baseline demonstrated a significant post-exercise increase in the concentrations of soluble transferrin receptors (P < 0.04), iron (P < 0.002) and IL-6 (P < 0.02), and to a significant post-exercise decrease in TAC. A significant increase in IL-6 concentration was also observed 24 h post-exercise. The exercise test conducted at the end of the follow-up period resulted in a significant decrease in TBIC and a significant increase in UIBC (P < 0.001), observed in both groups, both immediately post-exercise and after the resting period. Conclusion Supplementation with POM contributed to a significant strengthening of plasma antioxidant potential in the group of well-trained rowers, but had no effect on iron metabolism markers.

Abstract
This work contributes to the discussion on defect levels in Cu(In,Ga)Se2 photovoltaic material. CuInSe2- and Cu(In,Ga)Se2- based Schottky junctions, solar cells and thin films were investigated using complementary capacitance and current spectroscopic techniques. Depending on the applied technique and type of investigated structure, six different signals were observed. Out of the signals identified, three were ascribed to responses from bulk defects-two electron and one hole trap. The remainder were discussed in light of available in-literature models including carrier mobility freeze-out and non-ohmic back junction.

Abstract
AbstractThe structure-activity relationship analysis has been performed for trans- and cis-hydroxycinnamic acids, to determine their theoretical antioxidant pharmacophore. Based on the detailed conformational studies, the most stable rotamers have been selected. We have analyzed the descriptors of four antioxidant mechanisms important in free radical scavenging: hydrogen atom transfer, sequential proton loss electron transfer, single electron transfer - proton transfer and transition metal chelation, based on the B3LYP/6-311++G(2d,2p) calculations in vacuum and polar media. The results explain the activity difference between cinnamic acid and its derivatives. The descending order of antioxidant potential is as follows: caffeic > sinapinic ~ ferulic > p-coumaric > o-coumaric > m-coumaric ~ phenol. The results have shown that transisomers indicate higher reactivity than cis- and may be considered as good antioxidants. It has been determined that the highest antioxidant ability is related to the hydroxyl group in para position, supported by planar structure and stability of radical forms. π-Type delocalization of unpaired electron on aromatic ring, double bond and para O-atom is the key to radical stabilization. The ortho-dihydroxy substitution in benzene ring positively influences the ability to neutralize free radicals and makes caffeic acid the antioxidant pharmacophore of hydroxycinnamic acids.

Abstract
S-100 protein expression is present in various malignant tissues, yet its prognostic relevance is debatable. The aim was to assess in non-small cell lung cancer (NSCLC) patients' prognostic value of S-100 protein considered alone or in relation with other variables. Tumour samples taken from 86 NSCLC patients during resection were assayed for S-100 protein expression with the use of polyclonal DAKO ZO311 antibody. S-100 expression was found in 32 cases (37%). Positive staining was not correlated with clinical characteristics including age, sex, pathology type of tumour, stage and cigarette smoking. There was a tendency for simultaneous expression of S-100 and P53 protein (p=0.06). A median survival rate for the entire group was 2.3 years (95% CI, 0.9-3.6 years). The median and 5-year survival of patients with positive staining for S-100 protein was 1.5 years and 25%, respectively, compared with 3.0 years and 35%, respectively, in the S-100 negative group (p=0.17). In the final model of a multivariate analysis, S-100 protein expression in tumour cells was associated with significantly decreased survival (p=0.005). S-100 protein expression in tumour cells seems to be an independent predictor of poor prognosis in NSCLC patients.

Abstract
Objective: To evaluate the use of intravenous ketoprofen administration during varicose vein surgery undertaken under local anaesthesia. Setting: Regional general hospital in Poland. Patients: One hundred and six patients presenting with primary long saphenous varicose veins, including those with skin changes and leg ulceration. Interventions: Patients underwent sapheno-femoral ligation and long saphenous stripping under local anaesthesia including femoral nerve block, having first received an intravenous infusion of ketoprofen. Outcome measures: Patients recorded their level of discomfort or pain on a five-point scale. Blood pressure and pulse were also recorded. Results: One hundred and two patients found the level of analgesia produced by this technique to be acceptable, and 75 reported no discomfort at all. Conclusions: The combined use of intravenous ketoprofen and local anaesthesia allowed the treatment of all patients with superficial venous incompetence irrespective of their fitness for general anaesthesia.

Abstract
Prognostic value of p53 and PCNA expression in non-small cell lung cancer (NSCLC) remains controversial. In this study we determined the relevance of these abnormalities in terms of overall survival and disease-free survival in 95 NSCLC patients who underwent curative pulmonary resection. Expression of p53 was found in 44 samples (45%), expression of PCNA-in 79 samples (83%), and expression of both markers-in 35 samples (36%). There was no relationship between expression of either protein and major clinicopathological characteristics. Median survival for patients with and without p53 expression was 36 and 33 months, respectively and 5-year survival probability-29 and 37%, respectively (P=0.73). Median survival for patients with and without PCNA expression was 36 and 27 months, respectively and 5-year survival probability-35 and 25%, respectively (P=0.60). There was no significant difference in overall survival between particular groups of patients with tumors carrying four possible p53/PCNA phenotypes. In multivariate analysis including patient age, sex, tumor stage, tumor type and differentiation, p53 and PCNA expression, the only variable important for survival was stage of disease. These results suggest the lack of prognostic relevance of p53 and PCNA expression in surgically treated NSCLC patients.

Abstract
The aim of the study was to asses influence of selected epidemiologic and virusologic factors on the course of chronic hepatitis C (CHC). Data obtained from 550 CHC patients was analyzed (F/M: 241/309; age: 14-87, average age: 44.9 +/- 15.6). HbsAg and HIV-positive, as well as patients taking drugs were excluded from the study. Progression of the liver disease was assessed by the maximal ALT activity, presence of clinical or histopathological symptoms of hepatic cirrhosis, and 363 liver biopsy results. Clinical and histological data was analyzed depending on: patients sex, age (= 40, and > 40 years old), portal of infection (history data on transfusion or another source of infection), history of HBV infection (presence or absence of anti-HBc antibodies), and HCV genotype (1b or no-1b group). HCV genotype was determined in 170 patients by the use of commercial InnoLipa kit (Innogenetics). Statistical analysis was based on t-Student test and chi-squared test with or without Yates correction. It was proved that in patients over 40 years old or with history of transfusion inflammatory activity and liver fibrosis activity are significantly higher than in the rest of patients. More advanced age, transfusion and history of HBV infection are risk factors for hepatic cirrhosis development in CHC patients. Neither patient's sex nor HCV genotype were found to have significant influence on the course of CHC.

Abstract
The aim of our study was analysis of relation between HLA class II antigens and the liver disease severity in chronic hepatitis C (CHC) patients. The subject of analysis was data obtained from 134 CHC patients with disease confirmed by histopathologic test (F/M: 62/72; age 16-74; average age 41.4 +/- 12.7 yrs), HCV RNA-positive, HbsAg- and HIV-negative with no coexistence of any other liver diseases. Liver biopsy specimens were estimated according to Ishak's criterions (grading 0-18; staging 0-6). HLA DRB1 alleles were determined by a commercial method INNOLiPA DRB (Innogenetics, Belgium). Statistical analysis considered alleles occurring with frequency higher than 10%. The necroinflammatory activity (average grading score) was compared in groups of patients with- and without particular allele. The frequency of each allele's occurrence was analyzed according to patients sex, age and staging score of liver fibrosis. In statistical analysis t-Student test and chi-squared test with or without Yates' correction were applied. Statistically significant correlation was found between occurrence of DRB1*13 and DRB1*07 alleles and necroinflammatory activity intensification, and between occurrence of DRB1*13 allele and progression of liver disease. Mild liver damage, instead, expresses statistically significant relation with DRB1*11 allele.

Abstract
The aim of the study was to evaluate the prognostic relevance of p53 protein in non-small cell lung cancer. The 95 surgically treated patients were included (53 patients with squamous cell carcinoma, 29--with adenocarcinoma, 5--with large cell carcinoma, and 8--with mixed type). The protein was assessed immunohistochemically with the use of monoclonal antibodies DO7, DAKO. Positive staining was present in 44 patients. There was no survival difference between groups with and without protein (median survival--36 and 33 months, respectively; p = 0.86). In the multivariate analysis the only characteristics with prognostic impact in the entire group was stage of the disease. There was no correlation between the expression of p53 protein and disease-free survival. These results indicate that there is no prognostic relevance of p53 protein in non-small cell lung cancer.

Abstract
The total reflection x-ray fluorescence method (TRXRF) has been employed to determine of P, S, K, Ca, Cr, Mn, Fe, Ni, Cu, Zn, Se, Rb, Sr, and Pb concentration in the benign breast tumor tissue from 68 women and in the cancerous breast tissue from 26 women. Concentrations of most of elements show enhancement in cancerous breast tissue. Examined elements compete for binding sites in the cell, change its enzymatic activity, and exert direct or indirect action on the carcinogenic process accelerating the growth of tumors. Inhibition of enzymatic activity caused by variation in trace element concentrations results in immunological breakdown of the body system. An attempt has been made to correlate measured trace element concentrations with the clinical stage of cancer. Physical bases of used analytical method, experimental setup, and the procedure of sample preparation are described.
