Genome-wide association studies (GWAS) have successfully revealed numerous susceptibility loci for obesity. The PREDATORR study (2014) shows that in Romania, 346% of adults aged 20–79 y/o are overweight, and 31.4% are obese with a high risk of cardiometabolic complications, a number that puts almost 67% of Romania's population in the abnormal weight group. Our study aims to investigate the current status of the genetic foundation in metabolic disease associated with obesity, applied to a pilot group of patients specifically examining the impact of known polymorphisms and their haplotype of six food intake-regulating genes, namely leptin (LEP), leptin receptor (LEP-R), serotonin receptor (5HTR2A), ghrelin (GHRL), neuropeptide Y (NPY), and fat-mass and obesity-associated protein (FTO) with the following polymorphisms: LEP A-2548G, LEPR A-223G, 5HTR2A G-1439A, GHRL G-72T, NPY T-29063C, FTO A-T, and body mass index (BMI). A notable link between the LEP-2548 rs7799039 gene's AG genotype and the risk of obesity was observed, particularly pronounced in males aged 40–49, with an approximately seven-fold increased likelihood of obesity. The 5HTR2A rs6311 AA genotype was associated with a higher BMI, which was not statistically significant. The FTO rs9939609 gene's AA genotype emerged as a significant predictor of obesity risk. Besides these significant findings, no substantial associations were observed with the LEPR, 5HTR2A, GHRL, and NPY genes. Haplotype association analysis showed a suggestive indication of GRGMLA (rs7799039, rs1137101, rs6311, rs696217, rs16139, rs9939609 sequence) haplotype with a susceptibility effect towards obesity predisposition. Linkage disequilibrium (LD) analysis showed statistically significant associations between LEP and LEPR gene (p = 0.04), LEP and GHRL gene (p = 0.0047), and GHRL and FTO gene (p = 0.03). Our study, to the best of our knowledge, is one of the very few on the Romanian population, and aims to be a starting point for further research on the targeted interventional strategies to reduce cardiometabolic risks.

There has been a catastrophic loss of biodiversity in ecosystems across the world. A similar crisis has been observed in the human gut microbiome, which has been linked to "all human diseases affecting westernized countries". This is of great importance because chronic diseases are the leading cause of death worldwide and make up 90% of America's healthcare costs. Disease development is complex and multifactorial, but there is one part of the body's interlinked ecosystem that is often overlooked in discussions about whole-body health, and that is the skin microbiome. This is despite it being a crucial part of the immune, endocrine, and nervous systems and being continuously exposed to environmental stressors. Here we show that a parallel biodiversity loss of 30–84% has occurred on the skin of people in the developed world compared to our ancestors. Research has shown that dysbiosis of the skin microbiome has been linked to many common skin diseases and, more recently, that it could even play an active role in the development of a growing number of whole-body health problems, such as food allergies, asthma, cardiovascular diseases, and Parkinson's, traditionally thought unrelated to the skin. Damaged skin is now known to induce systemic inflammation, which is involved in many chronic diseases. We highlight that biodiversity loss is not only a common finding in dysbiotic ecosystems but also a type of dysbiosis. As a result, we make the case that biodiversity loss in the skin microbiome is a major contributor to the chronic disease epidemic. The link between biodiversity loss and dysbiosis forms the basis of this paper's focus on the subject. The key to understanding why biodiversity loss creates an unhealthy system could be highlighted by complex physics. We introduce entropy to help understand why biodiversity has been linked with ecosystem health and stability. Meanwhile, we also introduce ecosystems as being governed by "non-linear physics" principles—including chaos theory—which suggests that every individual part of any system is intrinsically linked and implies any disruption to a small part of the system (skin) could have a significant and unknown effect on overall system health (whole-body health). Recognizing the link between ecosystem health and human health allows us to understand how crucial it could be to maintain biodiversity across systems everywhere, from the macro-environment we inhabit right down to our body's microbiome. Further, in-depth research is needed so we can aid in the treatment of chronic diseases and potentially change how we think about our health. With millions of people currently suffering, research to help mitigate the crisis is of vital importance. [ABSTRACT FROM AUTHOR]

PREGNANCY , *PREGNANT women , *VIRUS diseases , *PREGNANCY outcomes , *INFECTION - Abstract
During pregnancy, hormonal and immune adaptations are vital for supporting the genetically distinct fetus during elevated infection risks. The global prevalence of HPV necessitates its consideration during pregnancy. Despite a seemingly mild immune response, historical gestational viral infections underscore its significance. Acknowledging the established HPV infection risks during pregnancy, our review explores the unfolding immunological changes in pregnant women with HPV. Our analysis aims to uncover strategies for safely modulating the immune system, mitigating adverse pregnancy consequences, and enhancing maternal and child health. This comprehensive narrative review delves into the existing knowledge and studies on this topic. [ABSTRACT FROM AUTHOR]

Despite the substantial decrease in mortality rates following a pancreaticoduodenectomy to less than 5%, morbidity rates remain significant, reaching even 73%. Postoperative pancreatic fistula is one of the most frequent major complications and is significantly associated with other complications, including patient death. Currently, there is no consensus regarding the ideal type of pancreatic anastomosis, as the question of the choice between a pancreaticogastrostomy and pancreaticojejunostomy is still open. Furthermore, worldwide implementation of an ideal pancreatic fistula risk prediction score is missing. Our study found several significant predictive factors for the postoperative occurrence of fistulas, such as the soft consistency of the pancreas, non-dilated Wirsung duct, important intraoperative blood loss, other perioperative complications, preoperative patient hypoalbuminemia, and patient weight loss. Our study also revealed that for patients who exhibit fistula risk factors, pancreaticogastrostomy demonstrates a significantly lower pancreatic fistula rate than pancreaticojejunostomy. The occurrence of pancreatic fistulas has been significantly associated with the development of other postoperative major complications, and patient death. As the current pancreatic fistula risk scores proposed by various authors have not been consensually validated, we propose a simple, easy-to-use, and sensitive score for the risk prediction of postoperative pancreatic fistula occurrence based on important predictors from statistical analyses that have also been found to be significant by most of the reported studies. The new pancreatic fistula risk score proposed by us could be extremely useful for improved therapeutic management of cephalic pancreaticoduodenectomy patients. [ABSTRACT FROM AUTHOR]

SKIN regeneration ,CHRONIC wounds & injuries ,MEDICAL personnel ,NEGATIVE-pressure wound therapy ,GROWTH factors ,STEM cell factor - Abstract
Background: Chronic wounds are a significant health problem with devastating consequences for patients' physical, social, and mental health, increasing healthcare systems' costs. Their prolonged healing times, economic burden, diminished quality of life, increased infection risk, and impact on patients' mobility and functionality make them a major concern for healthcare professionals. Purpose: This review offers a multi-perspective analysis of the medical literature focusing on chronic wound management. Methods used: We evaluated 48 articles from the last 21 years registered in the MEDLINE and Global Health databases. The articles included in our study had a minimum of 20 citations, patients > 18 years old, and focused on chronic, complex, and hard-to-heal wounds. Extracted data were summarized into a narrative synthesis using the same health-related quality of life instrument. Results: We evaluated the efficacy of existing wound care therapies from classical methods to modern concepts, and wound care products to regenerative medicine that uses a patient's pluripotent stem cells and growth factors. Regenerative medicine and stem cell therapies, biologic dressings and scaffolds, negative pressure wound therapy (NPWT), electrical stimulation, topical growth factors and cytokines, hyperbaric oxygen therapy (HBOT), advanced wound dressings, artificial intelligence (AI), and digital wound management are all part of the new arsenal of wound healing. Conclusion: Periodic medical evaluation and proper use of modern wound care therapies, including the use of plasma-derived products [such as platelet-rich plasma (PRP) and platelet-rich fibrin (PRF)] combined with proper systemic support (adequate protein levels, blood sugar, vitamins involved in tissue regeneration, etc.) are the key to a faster wound healing, and, with the help of AI, can reach the fastest healing rate possible.

Inguinal hernia repair represents one of the most frequent pathologies with surgical addressability. From the multitude of surgical procedures, a limited number still keep their indication in the current treatment of hernias. Open surgery, the exclusive repair method until recently, is associated with laparoscopic techniques with benefits that are at least superposable on those in open repair. We conducted a study, analyzing several types of procedures in open surgery and comparing them to each other, but also with the TAPP approach, which is still at the beginning in our service. The non-mesh procedures scored poorly in terms of recurrence, the duration of the surgical intervention, and complications of the pain type, the Lichtenstein procedure was frequently associated with non-infectious inflammatory complications, and the TAPP, which is still in the learning curve, presented a prolonged duration of the surgical intervention. The Lichtenstein procedure maintains its usefulness and represents the most frequent technique for sanctioning inguinal hernia, the non-mesh processes, less used lately, are more frequently preferred in situations where hernia strangulation is associated with a septic complication. Open surgery hernia repair remains a feasible option in the era of minimal invasiveness, especially under the conditions of performing a tension-free technique, for specific categories of patients or surgical services remaining the first intention solution.

MACULAR degeneration ,DEGENERATION (Pathology) ,DISEASE progression ,INFLAMMATION ,VISION disorders ,PATHOLOGIC neovascularization - Abstract
Age-related macular degeneration (AMD) is a complex, chronic, and progressive disease which affects the macular area, being one of the leading causes of irreversible vision loss worldwide. Specific alterations of retinal structure occur at the macular level, which regarding its severity can range from the presence of drusen to the development of geographic atrophy or choroidal neovascularization. AMD has long been considered a degenerative disease, but new studies highlight the role of inflammation present both in the atrophic form and in the exudative form. The present review is based on comprehensive research on PubMed and Web of Science databases, and it aims to describe the inflammatory pathways involved in AMD onset and progression. Understanding the molecules involved in AMD pathogenesis, and their mechanism of action, is crucial because they can be both biomarkers with a predictive role in disease management, as well as potential therapeutic targets.

Thyroid hormones are required for the physiological growth and maintenance of hair follicles. We aim to study the thyroid profile of patients with alopecia. This is a narrative review. PubMed literature was searched from 2013 to 2022. We followed different types of alopecia: alopecia areata (AA), androgenic alopecia in males and females, telogen effluvium (TE), frontal fibrosing alopecia (FFA), lichen planopilaris, and alopecia neoplastica (AN). AA shares a common autoimmune background with autoimmune thyroid diseases, either sporadic or belonging to autoimmune polyglandular syndromes. Some data suggested that AA is more severe if thyroid anomalies are confirmed, including subclinical dysfunction or positive antithyroid antibodies with normal hormone values. However, routine thyroid screening for patients with AA, if the patients are asymptomatic from a thyroid point of view and they have negative personal and family history of autoimmunity, remains controversial. TE, apart from the autoimmune type, associates thyroid anomalies of a hormonal assay (between 5.7% and 17%). FFA, mostly a postmenopausal entity (however, not exclusive), associates a higher prevalence of thyroid conditions (up to 50%) than the general population. However, these might have an age-dependent pattern, thus the association may be incidental since there are a limited number of studies. Overall, alopecia remains a very challenging condition for patients and physicians; a multidisciplinary team is required to improve the outcome and quality of life. The common autoimmune background is suggestive of some types of alopecia and thyroid disorders, yet, the underlying mechanisms are still a matter of debate. AA, TE, FFA, LPP, and, potentially, female pattern hair loss have been found to be connected with thyroid entities, thus a state of awareness from a dual perspective, of trichology and endocrinology, is helpful.

EISENMENGER syndrome ,COVID-19 pandemic ,PATHOGENESIS ,OBSTETRICIANS ,PREECLAMPSIA - Abstract
Mirror syndrome (MS) or Ballantyne’s syndrome is a rare maternal condition that can be life-threatening for both mother and fetus. The condition is characterized by maternal signs and symptoms similar to those seen in preeclampsia in the setting of fetal hydrops. Despite recent advances in the field of maternal-fetal medicine, the etiopathogenesis of MS remains elusive. For patients and doctors, the COVID-19 pandemic has become an extra hurdle to overcome. The following case illustrates how patients’ non-compliance associated with mirror syndrome and SARS-CoV-2 infection led to the tragic end of a 19-year-old patient. Therefore, knowledge of the signs and symptoms of mirror syndrome should always be part of the armamentarium of every obstetrician. [ABSTRACT FROM AUTHOR]

Background/Aim: Cardiac papillary fibroelastomas (CPF) are benign tumors, frequently asymptomatic, characterized by a mobile pedunculated mass that arises from the endocardium. When CPF is located in the left ventricle, it may protrude into the left ventricular outflow tract and affect hemodynamics. They are highly thrombogenic, and can also cause some life-threatening events such as cerebral and peripheral embolization. Case Report: We herein report a case of a 74-year-old female admitted to our center with palpitations and dyspnea on exertion. Her past medical history revealed that she had had a transient ischemic attack 7 months before presentation. Echocardiography and cardiac magnetic resonance imaging revealed an intracardiac mass anchored in the anteroapical interventricular septum without interference with aortic or mitral valve functionality. Surgical resection of the left ventricular mass was performed through the left apical ventriculotomy approach. Histopathological examination of the tumor was suggestive of papillary fibroelastoma. The postoperative course was uneventful. The patient was discharged home on the eighth postoperative day, with no recurrence at 6 months. Conclusion: Although left ventricular papillary fibroelastomas are benign tumors, they carry a high risk for embolic complications and therefore surgery should be proposed, the transapical approach being a safe and effective method.

Due to the wide introduction of screening tests, patients with neoplastic diseases of the uterine cervix trend to be diagnosed in early stages of the disease, and less invasive surgical procedures are needed in certain cases. In this respect, the technique of sentinel lymph node dissection has been widely implemented as part of the therapeutic strategy, indocyanine green (ICG) being one of the most reliable markers for sentinel lymph node detection. However, it seems that this agent is extremely useful in order to achieve better short-term and long-term results after cervical cancer surgery, due to its capacity to determine the uterine vascular perfusion in cases in which conservative treatment, such as trachelectomy, is performed, as well as to prevent and treat lower limb lymphedema. A literature review was conducted of the studies which focused on the role of ICG utility in cervical cancer patients besides sentinel lymph node detection, special focus was given to vascularization preservation and lower limb lymphedema prevention and treatment.

This study is aimed at investigating tumoral and inflammatory cells and the significance of the prognostic factors of pancreatic ductal adenocarcinoma (PDAC); it is also aimed at determining the role of immunohistochemistry in the diagnosis and prognosis of this neoplasm. Materials and Methods. 230 cases of pancreatic ductal adenocarcinoma were included in the study group; these cases were selected from the archives of the Department of Pathology of the Fundeni Clinical Institute over a ten-year period. Immunohistochemistry was performed using the following antibodies: MUC 1, CD 34, Factor VIII, CD 68, MMP-7, CEA, p21, p53, and Ki 67. Results. There were 133 male (57.8%) and 97 female (42.2%) patients included in this study, with ages between 20 and 81 years old (mean age: 58.2 years) and with tumors located in the pancreatic head (n = 196; 85.2%), pancreatic body (n = 12; 5.2%), and pancreatic tail (n = 20, 8.7%), as well as panpancreatic tumors (n = 2; 0.9%). Patients presented with early stages (IA and IB), with low pathologic grade (G1), with small size tumors (less than 1-1.5 cm), with tumors located in the head of the pancreas, (p53: negative; p21: positive; and CD 68: positive in peritumoral tissue), with low nuclear index (Ki 67 < 10%), without metastases at the time of surgery (had a better prognosis), and with a survival rate of about 7 months. Conclusions. Immunohistochemistry is useful for an accurate diagnosis, differential diagnosis, and establishment of additional factors that might have a prognostic importance. It is recommended to study peritumoral tissue from the quantitative and qualitative points of view to increase the number of prognostic factors. This study represents a multidisciplinary approach, and it is a result of teamwork; it presents histopathological methods of examination of this severe illness and describes only a part of the scientific effort to determine the main pathological mechanisms of this neoplasm.

Background/Aim: Endometrial cancer is one of the most commonly encountered malignancies among obese women worldwide, a strong causality relationship being established between the two entities. Furthermore, obesity is also associated with metabolic syndrome; the aim of this study was to investigate the effect of metabolic syndrome on the postoperative outcomes of patients with endometrial cancer. Patients and Methods: Data of 23 patients diagnosed with endometrial cancer and metabolic syndrome were retrospectively reviewed and compared to the those of a control group of patients diagnosed with endometrial cancer in the absence of metabolic syndrome. Results: Patients in the first group presented significantly higher values of body mass index when compared to the control group. There were no significant differences in terms of stage, histopathological subtype or degree of differentiation between the two groups. The completeness of cytoreduction was lower among patients with metabolic syndrome, however, this did not reach statistical significance (p=0.08). Although the rate of complete debulking was lower among those with metabolic syndrome, the rates of postoperative complications were significantly higher. Conclusion: The association of metabolic syndrome significantly influences the risk of postoperative complications in patients with endometrial cancer; moreover, in certain cases, it might preclude the achievement of freedom from residual disease.

Background/Aim: The presence of extensive lesions of peritoneal carcinomatosis is found in a significant number of cases of extended digestive resection surgery, such as subtotal colectomy. The aim of this study was to report a series of 17 cases that necessitated performing subtotal colectomy as part of cytoreductive surgery for advanced-stage ovarian cancer. Patients and Methods: Between 2012 and 2020 subtotal colectomy was associated as part of the debulking effort in 17 cases. Results: The median age at the time of surgery was 59 years, while the initial stage at the time of diagnosis was IIIC in 14 cases, and respectively IV in three cases. Optimal debulking surgery was achieved in all cases. The continuity of the digestive tract was reestablished in 11 cases, while in the remaining 6 cases a terminal ileostomy was performed. Conclusion: Extended digestive tract resections may be needed in certain cases in order to maximize the debulking effort in patients with advanced-stage ovarian cancer. [ABSTRACT FROM AUTHOR]

Background/Aim: Malignant transformation of mature cystic ovarian teratoma is a scarce eventuality, only rare cases being reported so far. Furthermore, development of this transformation in the setting of an abscessed tumor is even scarcer. The aim of this study was to report the case of a 47-year-old patient submitted to surgery for such a lesion. Case Report: The patient was investigated for diffuse pelvic pain and diagnosed with a 10×7×8 cm mass at the level of the left adnexa with imaging findings suggesting the presence of an ovarian teratoma. The patient was submitted to surgery involving a total hysterectomy with bilateral adnexectomy, lymphadenectomy and peritoneal biopsies. The histo -p athological examination demonstrated the presence ofs quamous cell carcinoma areas transformation in associationw ith areas of abscess. Postoperatively the patient was concurrent external radiotherapy. At one-year follow-up she is free of recurrent disease. Conclusion: Although malignisation of mature cystic ovarian teratoma is a rare event, it should not be omitted when mature ovarian teratoma is suspected; however, association between malignant transformation and abscess is a scarcer eventuality.

Background/Aim: The presence of “omental cake” has been considered since long as a negative prognostic factor in patients diagnosed with advanced-stage ovarian cancer. The aim of this paper was to study the impact of “omental cake” presence on the perioperative outcomes in advanced-stage ovarian cancer. Patients and Methods: Between 2015 and 2020, 85 patients were submitted to surgery for advanced-stage ovarian cancer. Results: Among cases diagnosed with “omental cake” the rate of complete cytoreduction was significantly diminished when compared to cases in which this entity was not revealed. In the meantime, the presence of omental cake among cases in which complete debulking was achievable was significantly associated with a higher number of digestive resections when compared to the other cases submitted to surgery and in which tumoral transformation of the omentum was encountered. Conclusion: The presence of “omental cake” is associated with a higher rate of incomplete resections. However, in cases in which complete debulking was achieved, the presence of omental cake was associated with a significantly higher number of digestive tract resections. [ABSTRACT FROM AUTHOR]

Background/Aim: Association between cervical cancer and uterine prolapse represents a scarce eventuality. This is a case series of 11 patients diagnosed with different stages of cervical cancer in association with uterine prolapse. Patients and Methods: Between 2014 and 2020, 11 patients were diagnosed with cervical cancer on prolapsed uterine cervix. Results: The mean age of patients at the time of uterine cervix diagnosis was 68 years. In six cases, the first intent treatment was surgery, while in the remaining five cases it consisted of radio-chemotherapy, followed by radical surgery. The perioperative and postoperative outcomes were compared to those reported in a similar series of patients diagnosed in similar stages of the disease, but in the absence of uterine prolapse, no significant differences being encountered. Conclusion: Although it represents an unusual situation, malignant transformation of the uterine cervix might be encountered even in cases presenting uterine prolapse. In such cases, the therapeutic strategy should be tailored according to the stage of the disease. [ABSTRACT FROM AUTHOR]

Background/Aim: Gastroenteropancreatic neuroendocrine carcinomas represent poorly differentiated neoplasms with a high capacity of spreading inducing the development of distant metastases. In such cases debulking surgery seems to offer a good chance for survival especially in well and moderately differentiated lesions. The aim of this study was to report the case of a 48-year-old patient submitted to surgery for moderately differentiated neuroendocrine gastric carcinoma with distant metastases. Case Report: The patient was initially investigated for hematemesis and weight loss and was diagnosed with a lesser curvature gastric tumor in association with liver and peritoneal metastases. Due to the extent of the disease, the patient was initially submitted to neoadjuvant chemotherapy followed by surgery with radical intent. At the time of surgery subtotal gastrectomy en bloc with total omentectomy, peritonectomy, cholecystectomy and atypical liver resection were performed. Moreover, the two ovaries presented large tumoral masses so total hysterectomy with bilateral adnexectomy was performed. The histopathological studies confirmed the presence of a moderately differentiated neuroendocrine gastric carcinoma with negative resection margins. Conclusion: Multiple visceral resections might be needed in order to maximize the debulking effort in metastatic gastric neuroendocrine carcinomas. [ABSTRACT FROM AUTHOR]

Ovarian cancer has the highest mortality rate among gynecological cancers. Early clinical signs are missing and there is an urgent need to establish early diagnosis biomarkers. MicroRNAs are promising biomarkers in this respect. In this paper, we review the most recent advances regarding the alterations of microRNAs in ovarian cancer. We have briefly described the contribution of miRNAs in the mechanisms of ovarian cancer invasion, metastasis, and chemotherapy sensitivity. We have also summarized the alterations underwent by microRNAs in solid ovarian tumors, in animal models for ovarian cancer, and in various ovarian cancer cell lines as compared to previous reviews that were only focused the circulating microRNAs as biomarkers. In this context, we consider that the biomarker screening should not be limited to circulating microRNAs per se, but rather to the simultaneous detection of the same microRNA alteration in solid tumors, in order to understand the differences between the detection of nucleic acids in early vs. late stages of cancer. Moreover, in vitro and in vivo models should also validate these microRNAs, which could be very helpful as preclinical testing platforms for pharmacological and/or molecular genetic approaches targeting microRNAs. The enormous quantity of data produced by preclinical and clinical studies regarding the role of microRNAs that act synergistically in tumorigenesis mechanisms that are associated with ovarian cancer subtypes, should be gathered, integrated, and compared by adequate methods, including molecular clustering. In this respect, molecular clustering analysis should contribute to the discovery of best biomarkers-based microRNAs assays that will enable rapid, efficient, and cost-effective detection of ovarian cancer in early stages. In conclusion, identifying the appropriate microRNAs as clinical biomarkers in ovarian cancer might improve the life quality of patients. [ABSTRACT FROM AUTHOR]

Telocytes (TCs), located ubiquitously in the internal organs of vertebrates, are a heterogeneous, recently described, cell population of the stromal space. Characterized by lengthy cytoplasmic extensions that can reach tens of microns and are called telopodes (Tps), TCs are difficult to see using conventional microscopes. It was the electron microscopy which led to their first identification and Popescu’s team the first responsible for the reconstructions indicating TCs ‘organization’ in a three-dimensional (3D) network that is believed to be accountable for the complex roles of TCs. Gradually, it became increasingly evident that TCs are difficult to characterize in terms of immunophenotype and that their phenotype is different depending on the location and needs of the tissue at one time. This review discusses the growing body of evidence accumulated since TCs were discovered and highlights how the complex interplay between TCs and stem cells might be of importance for tissue engineering and regenerative medicine.

In this review, we describe the current knowledge on calcium signaling pathways in interstitial cells with a special focus on interstitial cells of Cajal (ICCs), interstitial Cajal-like cells (ICLCs), and telocytes. In detail, we present the generation of Ca
2+ oscillations, the inositol triphosphate (IP3 )/Ca2+ signaling pathway and modulation exerted by cytokines and vasoactive agents on calcium signaling in interstitial cells. We discuss the physiology and alterations of calcium signaling in interstitial cells, and in particular in telocytes. We describe the physiological contribution of calcium signaling in interstitial cells to the pacemaking activity (e.g., intestinal, urinary, uterine or vascular pacemaking activity) and to the reproductive function. We also present the pathological contribution of calcium signaling in interstitial cells to the aortic valve calcification or intestinal inflammation. Moreover, we summarize the current knowledge of the role played by calcium signaling in telocytes in the uterine, cardiac and urinary physiology, and also in various pathologies, including immune response, uterine and cardiac pathologies.

Entering the new millennium, nobody believed that there was the possibility of discovering a new cellular type. Nevertheless, telocytes (TCs) were described as a novel kind of interstitial cell. Ubiquitously distributed in the extracellular matrix of any tissue, TCs are regarded as cells with telopodes involved in intercellular communication by direct homo- and heterocellular junctions or by extracellular vesicle (EVs) release. Their discovery has aroused the interest of many research groups worldwide, and many researchers regard them as potentially regenerative cells. Given the experience of our laboratory, where these cells were first described, we review the evidence supporting the fact that TCs release EVs, and discuss alternative hypotheses about their future implications.

MicroRNAs represent nonprotein coding small RNA molecules that are very stable to degradation and responsible for gene silencing in most eukaryotic cells. Increased evidence has been accumulating over the years about their potential value as biomarkers for several diseases. MicroRNAs were predicted to be involved in nearly all biological processes from development to oncogenesis. In this review, we address the importance of circulating microRNAs in different conditions associated with pregnancy starting with the implantation period to preeclampsia and we shortly describe the correlation between placental circulating miRNAs and pregnancy status. We also discuss the importance of microRNAs in recurrent abortion and ectopic pregnancy. [ABSTRACT FROM AUTHOR]

Over the past decades, we were witnessing spectacular molecular medicine advances. However, many of the reproductive medicine problems, such as fertility issues and premature birth still represent major challenges for obstetrics and gynecology worldwide. A new cell population – the telocytes (TCs) – were described in the interstitial space of many organs, and their possible implications in many important physiological and pathological processes should not be overlooked. In this article, we present a historical perspective outlining the landmarks in the discovery, evolution and achievements in the field of TCs over the last ten years. We focused on the potential roles of TCs in morphogenesis and maintenance of the normal three-dimensional architecture of tissues, in controlling of the stem cell microenvironment, as having anti-inflammatory and cancer-suppressing properties, participating in the immune surveillance, all mediated by direct homo- and heterocellular junctions or indirectly by extracellular vesicle release. Here, we overview the advances on TCs research in the reproductive organs (uterus and fallopian tube), accessory reproductive organs of female (mammary glands) and the temporary endocrine organ—placenta.

Telocytes (TCs) are new cellular entities of mesenchymal origin described almost ubiquitously in human and mammalian organs (www.telocytes. com). Different subtypes of TCs were described, all forming networks in the interstitial space by homo- and heterocellular junctions. Previous studies analysed the gene expression profiles of chromosomes 1, 2, 3, 17 and 18 of murine pulmonary TCs. In this study, we analysed by bioinformatics tools the gene expression profiles of chromosome 4 for murine pulmonary TCs and compared it with mesenchymal stem cells (MSCs), fibroblasts (Fbs), alveolar type II cells (ATII), airway basal cells, proximal airway cells, CD8(+) T cells from bronchial lymph nodes (TBL) and CD8(+) T cells from lungs (T-L). Key functional genes were identified with the aid of the reference library of the National Center for Biotechnology Information Gene Expression Omnibus database. Seventeen genes were up-regulated and 56 genes were down-regulated in chromosome 4 of TCs compared with other cells. Four genes (Akap2, Gpr153, Sdc3 and Tbc1d2) were up-regulated between one and fourfold and one gene, Svep1, was overexpressed over fourfold. The main functional networks were identified and analysed, pointing out to a TCs involvement in cellular signalling, regulation of tissue inflammation and cell expansion and movement.

Telocytes ( TCs) are described as a particular type of cells of the interstitial space (). Their main characteristics are the very long telopodes with alternating podoms and podomers. Recently, we performed a comparative proteomic analysis of human lung TCs with fibroblasts, demonstrating that TCs are clearly a distinct cell type. Therefore, the present study aims to reinforce this idea by comparing lung TCs with endothelial cells ( ECs), since TCs and ECs share immunopositivity for CD34. We applied isobaric tag for relative and absolute quantification ( iTRAQ) combined with automated 2-D nano- ESI LC- MS/ MS to analyse proteins extracted from TCs and ECs in primary cell cultures. In total, 1609 proteins were identified in cell cultures. 98 proteins (the 5th day), and 82 proteins (10th day) were confidently quantified (screened by two-sample t-test, P < 0.05) as up- or down-regulated (fold change >2). We found that in TCs there are 38 up-regulated proteins at the 5th day and 26 up-regulated proteins at the 10th day. Bioinformatics analysis using Panther revealed that the 38 proteins associated with TCs represented cellular functions such as intercellular communication ( via vesicle mediated transport) and structure morphogenesis, being mainly cytoskeletal proteins and oxidoreductases. In addition, we found 60 up-regulated proteins in ECs e.g.: cell surface glycoprotein MUC18 (15.54-fold) and von Willebrand factor (5.74-fold). The 26 up-regulated proteins in TCs at 10th day, were also analysed and confirmed the same major cellular functions, while the 56 down-regulated proteins confirmed again their specificity for ECs. In conclusion, we report here the first extensive comparison of proteins from TCs and ECs using a quantitative proteomics approach. Our data show that TCs are completely different from ECs. Protein expression profile showed that TCs play specific roles in intercellular communication and intercellular signalling. Moreover, they might inhibit the oxidative stress and cellular ageing and may have pro-proliferative effects through the inhibition of apoptosis. The group of proteins identified in this study needs to be explored further for the role in pathogenesis of lung disease. [ABSTRACT FROM AUTHOR]
