Abstract
BACKGROUND The lack of standardization of the norms and aesthetic concept of the lower third of the face and lips creates challenges in reconstructive surgery and aesthetic procedures. A large-scale, anthropometric measurements summary poses an alternative for establishing universal patterns. METHODS A systematic review was conducted by searching PubMed, Embase, Google Scholar and Web of Science using keywords: lip, face, aesthetics, beauty, anthropometry and Caucasian. Seventy records were included in the review and checked in detail in terms of available data. RESULTS The study contains a meta-analysis of twelve parameters with sufficient quantitative data-lip width, nose width, facial width, lower third of the face height, midline mandible height, total height of the upper and lower lip, upper and lower vermilion height, cutaneous upper lip height and nasolabial and mentolabial angle. CONCLUSIONS The review provides a detailed database of primary anthropometric studies of lips and perioral regions of the healthy Caucasian population. The attractiveness of the region is focused on uniformity of proportions. Notably, results acquired with different methods of measurement are not interchangeable. Despite many published anthropometric studies, systems for conducting the measurements and reporting the results are not sufficiently unified to quantitatively assess meticulous key aesthetic clinical parameters. LEVEL OF EVIDENCE I This journal requires that authors assign a level of evidence to each article.

Abstract
Surgical flaps are basic tools in reconstructive surgery. Their use may be limited by ischemia and necrosis. Few therapies address or prevent them. Genetic therapy could improve flap outcomes, but primary studies in this field present conflicting results. This systematic review and meta-analysis aimed to appraise the efficacy of external gene delivery to the flap for its survival in preclinical models. This review was registered with PROSPERO (CRD42022359982). PubMed, Embase, Web of Science, and Scopus were searched to identify studies using animal models reporting flap survival outcomes following any genetic modifications. Random-effects meta-analysis was used to calculate mean differences in flap survival with accompanying 95% CI. The risk of bias was assessed using the SYRCLE tool. Subgroup and sensitivity analyses were performed to ascertain the robustness of primary analyses, and the evidence was assessed using the GRADE approach. The initial search yielded 690 articles; 51 were eventually included, 36 of which with 1576 rats were meta-analyzed. VEGF gene delivery to different flap types significantly improved flap survival area by 15.66% (95% CI 11.80-19.52). Other interventions had smaller or less precise effects: PDGF-13.44% (95% CI 3.53-23.35); VEGF + FGF-8.64% (95% CI 6.94-10.34); HGF-5.61% (95% CI 0.43-10.78); FGF 3.84% (95% CI 1.13-6.55). Despite considerable heterogeneity, moderate risk of bias, and low quality of evidence, the efficacy of VEGF gene therapy remained significant in all sensitivity analyses. Preclinical data indicate that gene therapy is effective for increasing flap survival, but further animal studies are required for successful clinical translation.

Abstract
OBJECTIVE This study aimed to assess the utility of circulating miR-125b-5p, miR-199a-3p, miR-451a, and miR-3613-5p as biomarkers of endometriosis. STUDY DESIGN Patients with stage III or IV of endometriosis according to the revised American Society of Reproductive Medicine (rASRM) staging classification, as well as control women, were recruited. We created a prospective study conducted on a group of 48 patients (n = 25 controls, n = 24 endometriosis) who had laparoscopic surgery. Blood samples were taken and plasma miRNA levels were measured by quantitative real-time polymerase chain reaction (RT-qPCR) and assessed with AUC and ROC curves. RESULTS MiR-451a and miR-3613-5p were significantly decreased in the plasma of endometriosis patients. miR-451a had a receiver-operating characteristic (ROC) area under the curve 0.8283 and miR-3613-5p had a ROC area under the curve 0.7617. The concentration of circulating miR-125b-5p and miR-199-3p did not differ between endometriosis patients and controls. Plasma miRNA levels did not change with BMI, smoking status, fertility problems, or menstrual pain according to the VAS scale (p > 0.05). CONCLUSION Circulating miR-451a and miR-3613-5p levels significantly differed between endometriosis and controls. However, the levels of miR-451a were discordant with previous studies. Therefore, miR-3613-5p may have better potential as the endometriosis biomarker. Circulating miR-125b-5p and miR-199a-3p cannot be used as reliable markers of endometriosis.

Abstract
In this study, we aimed to investigate the influence of N-acetylcysteine (NAC) on the gene expression profile, neoangiogenesis, neutrophils and macrophages in a rat model of incisional wounds. Before creating wounds on the backs of 24 Sprague-Dawley rats, intradermal injections were made. Lidocaine-epinephrin solutions were supplemented with 0.015%, 0.03% or 0.045% solutions of NAC, or nothing (control group). Scars were harvested on the 3rd, 7th, 14th and 60th day post-surgery. We performed immunohistochemical staining in order to visualize macrophages (anti-CD68), neutrophils (anti-MPO) and newly formed blood vessels (anti-CD31). Additionally, RT-qPCR was used to measure the relative expression of 88 genes involved in the wound healing process. On the 14th day, the number of cells stained with anti-CD68 and anti-CD31 antibodies was significantly larger in the tissues treated with 0.03% NAC compared with the control. Among the selected genes, 52 were upregulated and six were downregulated at different time points. Interestingly, NAC exerted a significant effect on the expression of 45 genes 60 days after its administration. In summation, a 0.03% NAC addition to the pre-incisional anesthetic solution improves neovasculature and increases the macrophages' concentration at the wound site on the 14th day, as well as altering the expression of numerous genes that are responsible for the regenerative processes.

Abstract
BACKGROUND Our goal was to determine whether N-acetylcysteine (NAC) administered to the tumescent solution can reduce oxidative stress and increase autologous fat graft (AFG) viability. METHODS The study included 15 women with a mean age of 31.8 years (range 23-39 years) who underwent breast asymmetry correction with AFG harvested from both thighs. One thigh was infiltrated with a standard tumescent fluid (control graft) and other with a NAC-enriched tumescent fluid (NAC-treated graft). Each participant had breast MRI imaging before and 6 months after the procedure. Also, adipose tissue samples from each graft were subjected to biochemical analysis, flow cytometric assay and qRT-PCR to determine the markers of oxidative stress, angiogenesis and adipogenesis. RESULTS Concentration and activity of superoxide dismutase in the NAC-treated grafts turned out to be significantly higher than in the control grafts, in both fresh (p = 0.041 and p = 0.023, respectively) and frozen samples (p = 0.004 and p = 0.003, respectively). The level of nitric oxide in frozen samples from the control grafts was significantly higher than in the NAC-treated grafts (p = 0.009). iNOS was the only qRT-PCR target showing significant intergroup differences, with higher transcription levels observed in the control grafts (p = 0.027). Breast volumetric analysis demonstrated that the NAC-treated group had a 12.19% lower resorption rate than the control group, although it was found to be statistically insignificant (p = 0.149). No postoperative complications were observed during a 6-month follow-up. CONCLUSIONS Some results of this study are promising. Further studies on larger groups are needed to determine NAC impact on AFG.

Abstract
INTRODUCTION Pituitary adenomas (PAs), also known as a pituitary neuroendocrine tumours (PitNET), are usually benign tumours of the anterior lobe of the pituitary gland and account for the third most common intracranial neoplasm. The most common type of pituitary adenoma is lactotroph adenoma, in which dopamine agonists are the first-line treatment. Nevertheless, in selected cases surgery or even radiotherapy may be required. In the current study, we aimed to analyse all patients who underwent surgery due to intrasellar mass in order to evaluate frequency of particular pituitary tumours, clinical diagnosis, and pathology findings. MATERIAL AND METHODS We retrospectively analysed all cases of patients consecutively operated due to intrasellar mass between 1st January 2010 and 31st December 2018 at the Department of Neurosurgery, Military Institute of Medicine in Warsaw, Poland. RESULTS Our database included 2348 cases: 1390 women (59.2%) and 958 men (40.8%). The mean age for women was 48.4 years (SD ± 15.72; median 49) and for men 50.9 years (SD ± 14.94; median 53). In our cohort we found: 869 gonadotroph and null cell adenomas, 751 somatotroph and mammosomatotroph adenomas, 386 corticotroph adenomas, 71 plurihormonal adenomas, 59 craniopharyngiomas, 44 lactotroph adenomas, 18 purely thyrotroph adenomas, and other rare cases of pituitary tumours including one pituitary carcinoma metastasising to the liver (corticotroph origin). CONCLUSIONS We provide a comprehensive analysis of both clinical and pathological findings of the largest cohort of patients operated on for pituitary adenomas in one tertiary reference centre. To the best of our knowledge, this is the largest up-to-date published analysis in our country.

Abstract
Changes in gene expression profiles were investigated in 23 patients with Niemann-Pick C1 disease (NPC). cDNA expression microarrays with subsequent validation by qRT-PCR were used. Comparison of NPC to control samples revealed upregulation of genes involved in inflammation (MMP3, THBS4), cytokine signalling (MMP3), extracellular matrix degradation (MMP3, CTSK), autophagy and apoptosis (CTSK, GPNMB, PTGIS), immune response (AKR1C3, RCAN2, PTGIS) and processes of neuronal development (RCAN2). Downregulated genes were associated with cytoskeletal signalling (ACTG2, CNN1); inflammation and oxidative stress (CNN1); inhibition of cell proliferation, migration and differentiation; ERK-MAPK pathway (COL4A1, COL4A2, CPA4); cell adhesion (IGFBP7); autophagy and apoptosis (CDH2, IGFBP7, COL4A2); neuronal function and development (CSRP1); and extracellular matrix stability (PLOD2). When comparing NPC and Gaucher patients together versus controls, upregulation of SERPINB2 and IL13RA2 and downregulation of CSRP1 and CNN1 were characteristic. Notably, in NPC patients, the expression of PTGIS is upregulated while the expression of PLOD2 is downregulated when compared to Gaucher patients or controls and potentially could serve to differentiate these patients. Interestingly, in NPC patients with (i) jaundice, splenomegaly and cognitive impairment/psychomotor delay-the expression of ACTG2 was especially downregulated; (ii) ataxia-the expression of ACTG2 and IGFBP5 was especially downregulated; and (iii) VSGP, dysarthria, dysphagia and epilepsy-the expression of AKR1C3 was especially upregulated while the expression of ACTG2 was downregulated. These results indicate disordered apoptosis, autophagy and cytoskeleton remodelling as well as upregulation of immune response and inflammation to play an important role in the pathogenesis of NPC in humans.

Abstract
The objective of this study is to evaluate MMP-14 expression in odontoblasts and in the bulk of dental pulp of teeth with pulpitis; to determine the expression of microRNA-410 (miR-410) in pulp tissue, since sequence analysis suggests that miR-410 has potential binding site on MMP-14’s 3′UTR, and hence, can regulate expression of the latter one. Tissue samples of dental pulp from teeth with pulpitis and healthy (control) were formalin fixed and paraffin embedded (FFPE). Samples were examined using immunohistochemical staining for MMP-14 and the expression of miR-410 was evaluated using qRT-PCR. In both, healthy and inflamed pulp odontoblasts stained more intensively than remaining pulp tissue, but this difference was not statistically significant. More positive staining was observed in inflamed pulps compared to healthy pulps. Expression of miR-410 was found significantly lower in inflamed pulps than in healthy ones. In the two examined zones, odontoblasts and remaining pulp, miR-410 was expressed on a similar level. No statistically significant correlation of miR-410 and MMP-14 expression was found. We showed that inflammation changes the MMP-14 expression in pulp tissue and odontoblasts. This study demonstrates for the first time miR-410 expression in human dental pulp and that expression of this microRNA was downregulated in inflamed dental pulp and odontoblasts.

Abstract
Background Genetic alterations of TGF-β pathway members, including its transmembrane receptor, TGFBR1, may influence the course of HCV infection. Rs868 is a single-nucleotide polymorphism of the 3′UTR region of TGFBR1, located in a binding site for the conserved let-7/miR98 microRNA family. Previously, we demonstrated a favorable course of hepatitis C recurrence after liver transplantation in rs868 AG genotype of the transplanted liver when compared to rs868 AA. The aim of the present study was to confirm the biological effect of rs868. Material/Methods HepG2 cell line was transfected with luciferase vectors cloned with 3′UTR of TGFBR1 gene encompassing different rs868 alleles. Post-transplant liver biopsies from 61 patients with HCV-related end-stage liver disease were evaluated histopathologically and analyzed for the expression of TGFBR1 mRNA, let-7/miR98 microRNAs, HCV RNA load, and rs868 genotype. Results Luciferase expression was significantly lower in the A allele-containing vector. TGFBR1 mRNA and HCV RNA load were correlated negatively with let-7/miR98 microRNAs and this correlation was significantly stronger for rs868 AG compared to AA genotype. A strong positive correlation was demonstrated between TGFBR1 and HCV in both genotypes. In AG heterozygotes, let-7/miR98 microRNAs showed a strong negative correlation with periportal or periseptal interface hepatitis (Ishak A score). Conclusions There is a negative correlation between let-7/miR98 microRNAs and HCV viral load and TGFBR1 mRNA after liver transplantation. In the rs868 AG heterozygotes, this correlation was stronger and there was a negative correlation between let-7/miR98 and Ishak A score, which is in concordance with the previously demonstrated protective role of this genotype in post-transplant hepatitis C recurrence.

Abstract
In prostate cancer TIMP4 expression level fluctuates with tumor progression. The mechanism and factors influencing its expression remain unclear. The aim of the study was to test the hypothesis on regulation of TIMP4 by microRNA-200b-3p. The levels of TIMP4 and miR-200b-3p expression were determined by real time PCR in 27 prostate carcinomas and eight benign prostatic hyperplasia samples. We found that miR-200b-3p positively correlated with TIMP4 expression in cancer samples (r = 0.46; p < 0.02). Moreover, mean miR-200b-3p level and TIMP4 expression were both higher in cancer tissues compared to benign prostatic hyperplasia samples (p > 0.05). Next, to test probable mechanisms of the regulation androgen-sensitive human prostate adenocarcinoma cells (LNCaP) were transfected with synthetic-miR-200b-3p or its synthetic antagonist. Modulation of miR-200b-3p in LNCaP cells had an impact on TIMP4 expression confirming the observation made in analyzed clinical samples. Two targets of miR-200b-3p: ZEB1 and ETS1 were investigated subsequently as potential regulators of TIMP4, however, no effect of their modulation on TIMP4 expression in LNCaP cells was found. Concluding, miR-200b-3p mediates regulation of TIMP4 expression in prostate cancer but exact mechanism needs to be investigated.

Abstract
Endometrial cancer (EC) is the most common gynecological malignancy in Europe and North America. It is classified into two types exhibiting different characteristics and prognosis. Type I is an estrogen-dependent tumor, histologically classified as low grade and low stage, usually with an excellent prognosis. Type II EC is unrelated to estrogen stimulation and is characterized by a poor prognosis. MicroRNAs (miRNAs, miRs) are small non-coding RNA polynucleotides that regulate gene expression post-transcriptionally. Various dysregulations in microRNA expression are often considered to have an impact on the diagnosis, prognosis and overall survival in patients diagnosed with different types of cancers. Recent data suggest that microRNAs play an important role in the pathogenesis of EC. The aim of the study was to evaluate the involvement of matrix metaloprotease 14 (MMP-14) and microRNA-410 in formation of the EC tumor. To this end expression of MMP-14 and microRNA-410 was assessed within the cancer, transient and healthy zones in the histological sections of tumours using immunohistochemical staining and laser capture microdissection (LCM) followed by a quantitative real-time PCR. The results revealed significantly higher expression of MMP-14 in the cancer tissue zone in comparison to the healthy tissue zone, as well as a lower expression of microRNA-410 in the cancer zone compared with the healthy zone. This reverse correlation may suggest a regulatory role of miRNA-410 in modulating levels of MMP-14 in EC. This is the first report on such regulation in human endometrial cancer.

Abstract
The frequency of osteocytic lacunae, expressed as mean lacunae number per 1000 μm2 of measured bone, evaluated 65 days post intramuscular implantation of demineralized incisors is higher (1.10 ± 0.19) than in femoral (orthotopic) bone (0.91 ± 0.16). The surface of evaluated bones was measured by means of the "weight of bone picture". These results provide new data on the biology of ectopic bone.

Abstract
New data concerning the function of osteocytes as the central regulators of bone homeostasis are briefly outlined. It is established that osteocytes are the main target cells for parathormone. They are a rich source of sclerostin, the main inhibitor of osteoblast activity, and of the RANKL cytokine, the most important regulator of osteoclastogenesis. Under shear stress causing microinjury, osteocytes enter programmed cell death (apoptosis) and osteocyte apoptosis is a signal for nearby healthy osteocytes to activate osteoclasts to resorb bone.

Abstract
BACKGROUND Terminal hepatitis C is one of the leading indications for orthotopic liver transplantation (OLT). However, hepatitis C virus (HCV) reinfection occurs in almost all recipients and usually leads to progressive fibrosis and graft failure. Transforming growth factor-b (TGF-β) plays a part in transplanted liver cirrhosis, but nothing is known about the possible role of genetic diversity of TGF-β receptor system. Therefore, the aim of our study was to investigate whether genetic variation in 3' untranslated region (3'UTR) of TGF-β receptor type I (TGFBR1) gene is associated with recurrence and severity of hepatitis C and liver fibrosis following OLT in HCV-infected patients. MATERIAL AND METHODS The study group included 95 chronic hepatitis C patients following OLT. The recipients and donors were genotyped for 49245A>G (rs868) and 51976G>A (rs334349) single nucleotide polymorphisms (SNP). RESULTS Donor rs868 AA genotype was strongly associated with worse clinical course of recurrent hepatitis C. The rs868 AA group displayed more severe symptoms of hepatitis C during the follow-up and the fibrosis score in this group was significantly higher 3 years after OLT. CONCLUSIONS Clinical course of hepatitis C after OLT may depend on donor rs868 SNP located in TGFBR1 3'UTR.

Abstract
BACKGROUND BAG3 gene mutations have been recently implicated as a novel cause of dilated cardiomyopathy (DCM). Our aim was to evaluate the prevalence of BAG3 mutations in Polish patients with DCM and to search for genotype-phenotype correlations. METHODS We studied 90 unrelated probands by direct sequencing of BAG3 exons and splice sites. Large deletions/insertions were screened for by quantitative real time polymerase chain reaction (qPCR). RESULTS We found 5 different mutations in 6 probands and a total of 21 mutations among their relatives: the known p.Glu455Lys mutation (2 families), 4 novel mutations: p.Gln353ArgfsX10 (c.1055delC), p.Gly379AlafsX45 (c.1135delG), p.Tyr451X (c.1353C>A) and a large deletion of 17,990 bp removing BAG3 exons 3-4. Analysis of mutation positive relatives of the probands from this study pooled with those previously reported showed higher DCM prevalence among those with missense vs. truncating mutations (OR = 8.33, P = 0.0058) as well as a difference in age at disease onset between the former and the latter in Kaplan-Meier survival analysis (P = 0.006). Clinical data from our study suggested that in BAG3 mutation carriers acute onset DCM with hemodynamic compromise may be triggered by infection. CONCLUSIONS BAG3 point mutations and large deletions are relatively frequent cause of DCM. Delayed DCM onset associated with truncating vs. non-truncating mutations may be important for genetic counseling.

Abstract
Intramuscular implantation of demineralized and lyophilized rat bone matrix and murine lower incisors into thigh muscles of BALB/c mice results in deposits of bone adjacent to the implants, a phenomenon termed as ectopic osteogenesis. The yield of induced bone does not critically depend on the mass of implanted matrices, and thus on the quantity of bone morphogenetic proteins (BMPs) present in the implants. A positive correlation between bone matrix implant weight and the yield of induced bone was observed only 28 days post grafting, i.e. when endochondreal osteogenesis is completed and bone resorption has not advanced. A more consistent yield of bone induction wasobserved in the case of demineralized tooth implants. It is postulated that chondro/osteoinduction by demineralized, lyophilized matrix implants is not determined by the range of BMPs presumably released in proportion to implant size, but is rather limited by the population of responsive host mesenchymal cells.

Abstract
Initiating factors and mechanisms of tumor formation are poorly understood in nonfamilial pituitary adenomas. Alteration of intracellular pathways is an underlying event in numerous neoplasms. Among them, excessive activation of mammalian target of rapamycin (mTOR) pathway and its two main regulators, Akt and Erk, has been detected frequently in solid tumors. This study tests the activation of mTOR pathway in pituitary adenomas and its influence on their morphopathological features. Fifty-three pituitary adenomas were fresh frozen after surgery and analyzed by western blotting using phospho-specific antibodies. The impact of Akt and Erk activation on mTOR pathway was assessed in five primary cultures derived from the excised adenomas using selective kinase inhibitors. Statistical correlations of size, volume, Ki-67 %, Knosp's grading, and somatostatin receptor (SSTR) expression with the activation of mentioned kinases was performed. GHomas showed the highest frequency (71 %) and level of mTOR pathway activity comparing to other adenomas (33 %). No significant correlation was found between mTOR activation and any of the morphopathological features in the studied samples. mTOR kinase phosphorylation was independent of Erk and Akt in primary cultures. Erk activity was significant in all types of adenomas but was the highest in control samples. Its phosphorylation correlated inversely with the Knosp's grading in nonfunctional pituitary adenomas and directly with somatostatin receptor subtype 2 A expression in GHomas. Presented data point to the noteworthy mTOR activity in GHomas. However, the lack of correlation with morphopathological features, its independence of Erk and Akt phosphorylation, and high level of Erk activity in control pituitary necessitate further research for clarifying the role of these pathways in pituitary adenomas.

Abstract
Mesenchymal stem cells, derived from adipose tissue do not differ substantially from mesenchymal stem cells isolated from bone marrow stroma. They are able to differentiate in differentiating culture medium into various cell type of mesodermal lineage, but also into cells of ectodermal type. Their potency to differentiate toward osteogenic and adipogenic lineage is promising to be a ready source of cells for tissue regeneration.

Abstract
HCl-demineralized murine lower incisors were implanted intramuscularly into syngeneic BALB/c mice to induce heterotopic osteogenesis. Implants were exposed at the early, preosteogenic stage (4), or at the later, osteogenic stage (12) to the Moloney sarcoma virus (MSV), which within 3–4 days results in a sarcoma. The yield of bone induction was determined by weight of dry bone mass following NaOH hydrolysis of soft tissues. To verify the effect of this sarcoma on orthotopic local femoral bone, the dry mass of the tumor-exposed femora was measured and compared with the weight of MSV-unexposed contralateral controls. MSV-sarcoma or cells involved with their spontaneous rejection have a stimulatory effect on the periosteal membrane of the tumor-adjacent femoral bones, increasing their dry mass on average by 18%. No stimulatory effect on heterotopic bone induction was observed when the MSV sarcoma grew during the early, preosteogenic stage (4 onward), but when the tooth matrix had been exposed to such tumor at the already bone-forming stage, (12 onward), the yield of bone induction was enhanced. Thus, it is postulated that lesions induced by MSV during the early, preosteogenic stage inhibit recruitment of osteoprogenitor cells or degrade Bone Morphogenetic Proteins (BMPs) released by matrix resorbing inflammatory cells, whereas when acting on already existing bone they have a stimulatory effect.

Abstract
Cardiac rhabdomyoma (CR) is the most common heart tumor in children and is usually associated with tuberous sclerosis complex (TSC). Tuberous sclerosis complex is a genetic disorder caused by a mutation in either of 2 genes (TSC1 or TSC2) and characterized by the formation of hamartomas in multiple organs. The 2 TSC proteins, hamartin and tuberin, antagonize the mammalian target of rapamycin (mTOR) signaling pathway, thus regulating cell growth and proliferation. Recently, some trials treating TSC with the mTOR inhibitor rapamycin have been published; however, the impact of such treatment on heart tumors is not known. The aim of the present paper was to study the molecular pathobiology of CRs. Six CR samples were studied. The expression of S6K1, pErk, Erk, Akt, pAkt, 4E-BP1, hamartin, tuberin, mTOR, bcl-2, Bax, and Ki-67 was examined using immunohistochemistry and Western blot methods. Increased expression of Bax, mTOR, pS6K, pErk, and 4E-BP1 was found in all CR samples. Hamartin and tuberin expression was decreased in tumors versus normal heart tissues. This is the first study showing mTOR pathway dysregulation and an increased expression of proapoptotic Bax protein in CRs associated with TSC.

Abstract
Leptin, a hormone secreted by adipose tissue, but also by several other tissues, has a dual effect on bone, acting by two independent mechanisms. As a signal molecule with growth factor characteristics, leptin is able to stimulate osteoblastic cells and to inhibit osteoclast formation and activity, thus promoting osteogenesis. However, as a molecule which stimulates sympathetic neurons in the hypothalamus, leptin indirectly inhibits bone formation. This inhibitory effect of leptin mediated by activation of sympathetic nervous system can be abrogated by application of blood pressure-reducing beta-blockers, which also inhibit receptors of hypothalamic adrenergic neurons.

Abstract
Autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED) is an autosomal-recessive autoimmune disease caused by autoimmune regulator gene mutations. The aim of this study was to examine the mutation profile of Polish APECED patients, determine the carrier rate of the most frequent mutation(s) and estimate disease prevalence. While studying 14 unrelated patients, we identified three novel mutations (c.1A>T, affecting the start codon; [IVS1 + 1G>C; IVS1 + 5delG], a complex mutation affecting splice site; c. 908G>C, p.R303P, a missense mutation in plant homeodomain (PHD) and three previously reported mutations (c.769C>T, p.R257X; c.967_979del13bp, C322fsX372; c.931delT, p.C311fsX376). Eleven patients had mutations on both chromosomes, whereas in three patients only a single alteration with proven or likely pathogenic effect was detected. The most frequent was the p.R257X mutation (71% of chromosomes); its carriage rate was assessed in the background population. Analysis of 2008 samples showed eight heterozygotes, indicating the frequency of 0.40% (1:250) and the disease prevalence - 1:129,000 (95% confidence interval: 1:555,000 to 1:30,000). Comparison with an epidemiological estimate (1:619,000, derived for women) suggested that in Poland, APECED is underdiagnosed. Among the patients, no genotype/phenotype correlations were found, but we noted that women had earlier onset of hypoparathyroidism (p < 0.02) and were younger at diagnosis (p < 0.05) than men.

Abstract
Hyaluronic acid (HA) is a glycosaminoglycan composed of alternating N-acetyl-D-glucosamine and D-glucuronic acid moieties. HA is an ubiquitous component of connective tissue where it forms matrix and plays an important role in the maintenance of matrix structure and water balance. The viscoelastic properties of HA derivatives and nonimmunogenicity has provided its use in a number of pharmaceutical applications. Ability of HA to create and fill space by organizing and modifying the extracellular matrix is widely used for soft tissue augmentation to limit age-related and photoinduced skin aging, but also may be used for correction of facial lipodystrophy and to prevent reccurence of hypertrophic scars or keloids. Furthermore HA may be employed as a surgical aid in ophthalmology or to reduce knee pain and joint motion in patients with osteoarthritis. In children HA may become an alternative to the open surgery for the management of vesicoureteral reflux.

Abstract
In the last decade, statins became widely used drugs in hypercholesterolemia treatment. Several studies have demonstrated that statins may also be successfully administered in the treatment of osteoporosis. There are, however, no reports regarding the effect of statins on heterotopic ossification (HO). In this paper, we examined the influence of fluvastatin on heterotopically induced bone formation in mice. HO was induced by implantation of rat-derived demineralized bone matrix (DBM) into intramuscular pockets in CFW mice. Mice in the experimental groups received fluvastatin at 3.6 mg/kg per day for 25 consecutive days whilst mice in the control group received placebo. Twenty five days after DBM implantation blood samples were collected to measure total serum cholesterol (TC), triglycerides (TG), low density lipoprotein cholesterol (LDL-C) and alkaline phosphatase (AP) activity. Mass of mineral deposited in the induced ossicle was established after hydrolysis of soft tissues surrounding the induced ossicles. In fluvastatin-treated mice, the mass of mineral deposited in heterotopically induced ossicles and AP serum concentration were significantly increased while TG and TC concentrations were decreased, when compared to mice receiving placebo. These results show that administration of statins, in some instances, may affect heterotopic ossification and that during hypocholesterolemic treatment of patients with predisposition to HO, following hip arthroplasty, such treatment may increase risk of HO.

Abstract
Hypertrophic chondrocytes, commonly considered as terminal cells designated to apoptotic elimination in the model of endochondral osteogenesis, are accordingly to the new concept based on histochemical, immunohistochemical, biochemical and cytological analysis, able to switch their metabolism and enter the osteoblastic differentiation path. According to this concept, some osteocytes in model of endochondral osteogenesis are derivative of hypertrophic chondrocytes. Also non-hypertrophic chondrocytes are able to transdifferentiate toward osteogenic cells, and the bone formed by such mechanism is termed "transchondroid bone".

Abstract
Medulloblastoma (MB) is the most common malignant brain tumour in children. Its aetiology is unknown, although several signalling pathways controlling cell proliferation are thought to participate in the progress of the neoplasm. Mutations of the genes encoding proteins participating in the pathways triggered by embryonic growth factors like Sonic hedgehog (Shh) or WNT are often found in MB. Another model of MB development is overexpression or mutation of several types of growth factor receptors, including IGF-IR, EGF-R and PDGFR, that have the ability to activate cellular kinases responsible for promoting cell proliferation. In order to test this hypothesis, in the current paper we tested the activation of two kinases, Akt/PKB (protein kinase B) and Erk (extracellular signal-regulated kinase) and their substrates in 10 sporadic medulloblastoma cases. We show that MBs are a highly heterogeneous group of tumours that show upregulation of various signalling pathways. Nevertheless, both Akt and Erk may contribute to the progression of MB, triggering, at least in some cases, the mTOR (mammalian target of rapamycin) pathway, controlling translation of several cell cycle-related proteins. We hypothesize that Akt and Erk activation may also be associated with downregulation of protein phosphatase 2A (PP2A).

Abstract
Several studies have demonstrated the pleiotropic effects of statins. Since Wang and associates reported that in rabbits lovastatin reduced steroid-induced bone loss, numerous authors have confirmed these data, however, others have reported conflicting results. In this study, the effects of fluvastatin on bone formation were investigated in early and late phase of osteogenesis. In the first set of experiments (early phase of osteogenesis) CFW/Ll mice were randomly divided into three groups. Two groups were injected with Moloney-murine sarcoma virus (Mo-MSV) into right thighs to induce orthotopic bone formation. Mice in the experimental group received fluvastatin for 11 consecutive days. Thirty days after Mo-MSV inoculation, total serum cholesterol, triglycerides, high- and low-density lipoprotein cholesterol, alkaline phosphatase (AP) were measured and bone mineral increase was calculated. In the second set of experiments (late phase of osteogenesis), fluvastatin was administered from day 11 after Mo-MSV inoculation for 20 consecutive days. Fluvastatin administration in the early phase of osteogenesis made no significant difference in average bone increase compared with mice receiving placebo. Lipid profile and AP were not significantly affected. During late phase of osteogenesis, the average increase in femural dry mass was significantly lower in the group of mice receiving fluvastatin than in the control group. Also, Mo-MSV-initiated tumors disappeared earlier in mice treated with fluvastatin. This may be attributed to the antioncogenic potential of fluvastatin. These results also point out that orthotopic bone formation at the sites of Mo-MSV inoculation in mice seems to be a useful model to examine the pleiotropic effects of statins.

Abstract
Inhibition of the proteasome, a multicatalytic proteinase complex, is an attractive approach to cancer therapy. Here we report that a selective inhibitor of the chymotrypsin-like activity of the proteasome, PSI (N-benzyloxycarbonyl-Ile-Glu(O-t-butyl)-Ala-leucinal) may inhibit growth of solid tumors not only through apoptosis induction, but also indirectly--through inhibition of angiogenesis. Two murine tumors: colon adenocarcinoma (C-26) and Lewis lung carcinoma (3LL) were chosen to study the antitumor effect of PSI. In an in vivo model of local tumor growth, PSI exerted significant antitumor effects against C-26 colon carcinoma, but not against 3LL lung carcinoma. Retardation of tumor growth was observed in mice treated with both 10 nmoles and 100 nmoles doses of PSI and in the latter group prolongation of the survival time of tumor-bearing mice was observed. PSI inhibited angiogenesis in the C-26 growing tumors with no such effect in 3LL tumors. Unexpectedly, that activity was associated with upregulation of vascular endothelial growth factor (VEGF) at the level of mRNA expression and protein production in C-26 tumors treated with PSI. C-26 cells treated with PSI produced increased amounts of VEGF in vitro in a dose- and time-dependent manner. We demonstrated that in C-26 colon adenocarcionoma higher VEGF production may render endothelial cells susceptible to the proapoptotic activity of PSI and is associated with inhibition of tumor growth.

Abstract
Syngeneic, allogeneic and xenogeneic (rat) freshly isolated bone marow cells + stromal cell cultures maintained in vitro for 10-30 days, as well as non-adherent cells removed from these cultures on 3rd-4th day were injected into the kidney parenchyma of mice, immunosuppressed with hydrocortisone. In syngeneic grafts the immunosuppression was omitted. In all transplant systems bone tissue was formed inside the kidney with 20% to 32% variation. Bone produced by allogeneic and xenogeneic cells is subject to rejection when immunosuppression ceases, as the bone formed is of donor origin. The "floating" cells, regardless of the transplant system, normally discarded during media replacement, turned out to be efficient bone producers. This notion is of practical implication when bone marrow cells are used for bone healing.

Abstract
Intradermal administration of concanavalin A, a potent T-cell mitogen, into an ear lap resulted in activation of chondrogenesis and stimulation of epidermis proliferation. This proliferation is sometimes invasive in character (pearls and epidermal nests form in the underlying connective tissue) but never turns into true cancerous lesions. This reaction can be delayed, but not prevented, by the prostaglandin inhibitor indomethacin. Stimulation of epidermis proliferation was also caused by administration of other immunomodulators, such as carrageenan type IV, Moloney sarcoma development, and rarely in the course of GvHr, but to much lesser degree than with concanavalin A. It is suggested that the same growth factors, which are mediators of local chondrocyte stimulation, are also mediators of keratinocyte activation.

Abstract
Small pieces (ca. 2-3 x 3-5 mm) of the urinary-tract mucosa from noninvasive papillary transitional-cell carcinomas of the bladder (ca. urotheliale papillare, n = 33), invasive transitional-cell carcinomas of the bladder (ca. urotheliale papillare infiltrans, n = 6, papillary transitional-cell carcinomas of the bladder with squamous metaplasia (ca. urotheliale papillare cum metaplasia planoepitheliale, n = 4), transitional-cell carcinomas in situ (ca. urotheliale in situ, n = 2), and squamous-cell carcinomas of the bladder (ca. planoepitheliale, n = 2) were grafted intramuscularly into cortisone-immunosuppressed mice to test the ability of transformed transitional epithelium to induce heterotopic osteogenesis. Altogether, 156 implants from 47 cases of urinary bladder carcinoma were performed. Histological examination of implants, excised 10-17 days later, revealed relatively good survival of the grafted epithelium, which had proliferated and, in some cases, formed cysts and islands but failed to induce heterotopic osteogenesis in the surrounding host tissues. In nine implants prepared from four cases (noninvasive papillary transitional-cell carcinoma of the bladder and invasive papillary transitional-cell carcinoma of the bladder, two cases each) a small amount of cartilage and/or bone was found in the stroma of grafted tissue. The rarity of this phenomenon--together with the observation that implants of normal human urinary-tract mucosa have never induced the formation of cartilage/bone, whereas in a similar system, dog or guinea-pig grafts are osteogenic--suggests that the cartilage/bone present in the stroma of implanted cancers is the result of metaplasia of the stroma of the neoplasm and not the product of any osteoinductive potency of human urothelium.
