Lipopolysaccharide hyporesponsiveness: protective or damaging response to the brain? Marie-Christine Pardon Lipopolysaccharide LPS endotoxins are widely used as experimental models of systemic bacterial infection and trigger robust inflammation by potently activating toll-like receptors 4 TLR4 expressed on innate immune cells.
Their ability to trigger robust neuroinflammation despite poor brain penetration can prove useful for the understanding of how inflammation induced by viral infections contributes to the pathogenesis of neurodegenerative diseases. A single LPS challenge often result in a blunted inflammatory response to subsequent stimulation by LPS and other TLR ligands, but the extent to which endotoxin tolerance occur in the brain requires further clarification.
LPS is also thought to render the brain transiently resistant to subsequent condyloma acuminata literature review injuries by attenuating the concomitant pro-inflammatory response. While LPS hyporesponsiveness and preconditioning are classically seen as protective mechanisms limiting the toxic effects of sustained inflammation, recent research casts doubt as to whether they have beneficial or detrimental roles on the brain and in neurodegenerative disease. These observations suggest that spatio-temporal aspects of the immune responses to LPS and the disease status are determinant factors.
Endotoxin tolerance may lead to a late pro-inflammatory response with potential harmful consequences.
And while reduced TLR4 signaling reduces the risk of neurodegenerative diseases, up-regulation of anti-inflammatory cytokines associated with LPS hyporesponsiveness can have deleterious consequences to the brain by inhibiting the protective phenotype of microglia, aggravating the progression of some neurodegenerative conditions such as Alzheimer s disease.
Beneficial effects of LPS preconditioning, however appear to require a stimulation of anti-inflammatory mediators rather than an attenuation of the pro-inflammatory response.
PDF 2. To better understand this class of materials and its properties, an overview on dendrimers and gold nanoparticles is needed. Dendrimers are known for their biomimetic properties and they are often compared with proteins due to their globular shape.
condyloma acuminata literature review Dendritic structures make excellent drug delivery systems and their ability to detect or target specific cells and to release active agents in a controlled manner when using adequate functionalization was already proven. Moreover, dendrimers can envelop other functionalized nanoparticles and create even more efficient targeting and release systems. Gold nanoparticles are already being used in the biomedical field in applications like sensing, photodynamic therapy, therapeutic agent delivery and diagnostics.
Their high applicability is due to their optical properties, also called quantum size effect, given by the interaction between light and electrons onto the surface of the gold nanoparticles. There are three main types of gold dendritic structures: gold-dendrimer nanocomposites, dendrimer-entrapped nanoparticles DENPs and gold monocrystalline dendritic growths.
Gold nanoparticles AuNPs -dendrimer structures combine the therapeutic properties of AuNPs with dendrimer s reactivity and biological membrane crossing ability. Corresponding author: Dan Eduard Mihaiescu, Chem. Cirrhosis is characterized by formation of nodules from regenerative nodules to dysplastic nodules, followed by HCC. Thus, the differential diagnosis of hypervascular hepatic lesions is important, especially in the nodules smaller than 2 cm, although their characterization may be difficult even when histopathology is used.
A multistep approach with the comparison of clinical data, pathological findings and imaging features is useful for a more accurate diagnosis. MRI has the ability to assess the same lesions condyloma acuminata literature review as CT and to better characterize the enhancement patterns of nodules combined with the lack of irradiation.
Moreover, new liver specific contrast agents and imaging techniques as diffusion-weighted DWI sequences are available. Regenerative and low-grade dysplastic nodules demonstrate contrast enhancement similar to that of surrounding liver parenchyma, compare to high-grade dysplastic nodules, which may show arterial enhancement similar to that seen in HCC.
We present a review of the MR imaging and histopathological features of hypervascular nodules in the cirrhotic liver, with reference to the transition from dysplasia to HCC. This anatomical region is passed by superficial noble anatomical structures arteries, veins, nerves that are often exposed in post-traumatic or post-excisional defects.
The elbow joint has a high tendency to stiffness or ankylosis even after short immobilization. The pedicled perforator flaps, based on source vessels from the anastomotic arcades of the elbow seem to be an efficient and reliable reconstructive choice. The flap cancer in abdominal lymph nodes a good local coverage, replacing like with like, has minor donor site morbidity and contrary to the free flaps, allows the very early beginning of physical therapy starting with the first postoperative day.

This paper represents a review of the literature concerning this problem. The sentinel lymph node SLN significance in colorectal cancer: methods and results. The presence of lymph nodes metastasis indicates the necessity of adjuvant chemotherapy but exact classification of the N stage requires at least 12 lymph nodes to be pathologically examined.
The sentinel lymph node SLN is considered to be the closest lymph node to the tumor, bearing the highest risk of malignant cells colonization.

The main advantage of the sentinel lymph node mapping in colorectal cancer is identification and separate pathological examination of the nodes carrying the highest risk of metastasis. There are still open questions regarding the best method for sentinel lymph node mapping in vivo or ex vivothe factors influencing it, which substance is better for identification and which are the best histological methods and markers to be used. Numerous studies have discussed the quality and applicability of the method, but the importance of condyloma acuminata literature review SLN in colorectal carcinoma remains an open condyloma acuminata literature review.
Circadian malfunctions in depression - neurobiological and psychosocial approaches Florina Nechita, Mihail-Cristian Pirlog, Anca Livia Chirita Depression leads to disturbances in physiological rhythms, which result in disturbances in circadian sleep-wake cycles, hormonal secretion patterns and fluctuations in mood, all of which can be objectively measured. These disturbances, which are associated with depression, can be also used to define depression.
Beyond these transversal time-related symptoms, there are the longitudinal time-related symptoms, since depression evolves over a long period of time, with a profound impact on a person s life and is often associated with long-term psychosocial consequences Mendlewicz, The circadian rhythm reflects an approximate hour cycle in the biochemical, physiological and behavioral processes of living entities, which crucially influences human well-being and health.
Increasing evidence from clinical and neurobiological research suggests that disrupted temporal organization impairs behavior, cognition, mood, sleep and social activity and may be implicated in mental disorders. It has been proposed that circadian malfunction is a major core feature of mood disorders, depression in particular.
In depressed patients, circadian rhythms and homeostatic processes are disrupted, thereby affecting mood, sleep, activity and a variety of biological functions such as hormone secretion and body temperature Hajak and Landgrebe, Sleep difficulties are among the most current symptoms in depressed patients. Insomnia is often the condyloma acuminata literature review why depressed patients seek help and relief of sleep disturbance may encourage compliance with antidepressant treatment.
Apart from the discomfort that sleep problems produce, they may lead to exhaustion, poor functioning and they are associated with an increase in suicide risk Wilson et al. LVD was higher in advanced stages and metastasizing carcinomas. A negative linear correlation between proliferation and maturity of the lymphatic vessels was found. The study indicated a strong association between lymphatic proliferative activity and lymph node metastases, suggesting the need for targeted antilymphangiogenic therapies in OSCC.

Morphological aspects in tuberculosis of oral cavity - our experience and a review of the literature attempt Mihai Raul Popescu, Iancu Emil Plesea, Marian Olaru, Irina Ruxandra Strambu, Adrian Ioan Fronie, Ileana Octavia Petrescu, Florin Petrescu, Alexandru Stefarta, Paraschiva Postolache, Mihaela Popescu Aim: The authors continue a started series of articles about extrapulmonary tuberculosis EPTB with the assessment of the mycobacterial lesions discovered on tissue samples of the oral cavity structures in the Department of Pathology of the Emergency County Hospital of Craiova, Romania, and the condyloma acuminata literature review of the cases reported tratamentul papiloamelor plate pe față the literature condyloma acuminata literature review, between and Materials and Methods: The studied material consisted, for our series, of samples obtained by biopsy or surgical excision, including the salivary glands and excluding the lymph nodes from 17 patients histopathologically diagnosed with tuberculosis and, for review series, papers selected from PubMed database.
Results: The number of cases reported increased throughout the studied period. Most cases came from departments connected with oral pathology but also from various medical and surgical departments. In general, patients were adults with a mean age of around 40 years, with twice as many men than women, without no condyloma acuminata literature review or no clinical suspicion of tuberculosis TB at the admission.
When reported, the provisional diagnostic was oriented most often towards neoplastic proliferation. There was no information about human immunodeficiency virus HIV testing in more than half of the case reports but when existed the result was two-fold more frequently negative than condyloma acuminata literature review. TB lesions condyloma acuminata literature review the oral cavity were more often primary infections than secondary.
From morphological point of view, the granuloma cellular population included both epithelioid and Langhans cells in most of the cases, the necrosis, present in most of the cases, displayed the whole range of morphological features, but mainly the acidophilic, microgranular one and the perilesional fibrosis was absent in almost all of the cases. As a whole, well-differentiated granulomas were the most frequent, usually of grade II - reactive type homeostatic but with a significant contingent of grade I - hyperplastic protective granulomas.
Local extension was usually not present and, when present, regional lymph nodes were mainly involved. Coexistence of TB lesions with a neoplastic proliferation was very rare and when present it was mainly located in the parotid gland.
Apart from this general profile, particular, individual profiles were observed for each of the oral cavity segments. Conclusions: TB lesions in the oral cavity are indeed a rare event but no swelling or ulcer in the oral cavity should be disregarded by the medical practitioners because it could be tuberculosis.

The potential of h-CMSCs and h-AMSCs was assessed trough growth kinetics, differentiation towards osteogenic and neurogenic lineages and immunohistochemistry. Conclusions: Placental-derived mesenchymal stem cells show remarkable differentiation potential under appropriate culture conditions. The expressions of osteogenic and neurogenic markers support the conclusion that placenta is an excellent mesenchymal stem cell source for osteogenesis as well as neurogenesis.
Future research in this area will identify the best clinical applications for this new source of stem cells. Dendritic cells in melanoma - immunohistochemical study and research trends Roxana-Ioana Nedelcu, Daniela-Adriana Ion, Cosmin Adrian Holeab, Mirela-Daniela Cioplea, Alice Brinzea, Sabina Andrada Zurac Cutaneous dendritic condyloma acuminata literature review play multiple physiological roles and are involved in various pathophysiological processes.
Research studies of dendritic cells abound in the medical literature. Nevertheless, the role of dendritic cells in melanoma regression phenomenon is not completely understood.
We conducted a scientometric analysis in order to highlight the current state on research regarding dendritic cells and melanoma. We also performed an immunohistochemical study, using specific markers for dendritic cells CD1a, langerin. We evaluated the frequency and distribution of dendritic cells in areas of tumor regression compared to the areas of inflammatory infiltrate of melanoma without regression. The immunohistochemical study we performed revealed that dendritic cells are more frequent in the regressed areas, comparing with non-regressed ones.
In regressed areas, dendritic cells have a predominant nodular pattern 19 casesfollowed by diffuse isolate pattern eight cases and mixed pattern diffuse and nodular three cases. In melanoma without regression, most cases presented condyloma acuminata literature review diffuse pattern 27 cases of dendritic cells distribution. In conclusion, our immunohistochemical study stressed differences between frequency and distribution of dendritic cells located in the melanoma with regression and melanoma without regression.
These data suggest that dendritic cells are involved in the regression phenomenon.

Semiological characters and morphopathological-radiological correlations in duodenal malignancy Ana Magdalena Bratu, Daniel Alin Cristian, Iulia Alecsandra Salcianu, Constantin Zaharia, Gheorghe Iana, Bogdan Valeriu Popa, Victorita Stefanescu Localized duodenal neoplasms are relatively rare entities, most often representing invasions of the duodenum by malignant masses developed in the duodeno-pancreatic region. The paper makes a more exact analysis of radiological semiology of duodenal localized tumors and seeks to determine through this analysis the role of radiological examinations in the support for the anatomopathologist.
The study group included 17 cases of duodenal localized tumors, nine cases of which have been shown to be vaterian ampulloma and eight malignant tumors of the duodenum. All cases were CT computed tomography examined and two-thirds were performed conventional radiological examinations, prior to CT examination.
Pre-operatively, all cases were evaluated endoscopically, and in three of them bile prostheses were made. CT examination protocol included a native acquisition and post-administration of intravenous contrast agent in both the arterial phase and in parenchymal and venous phase.
The acquisition was made with 3 mm thin sections, subsequently coronal and sagittal plane reconstructions being made. The paper tries to establish possible correlations between the morphopathological aspect and the radio-imaging semiological characteristics of lesions. Evidence based demonstration of the concept of field cancerization by p53 expression in mirror image biopsies of patients with oral squamous cell carcinoma - an immunohistochemical study Alka H.
Hande, Deepali P. Mohite, Minal S. Chaudhary, Mimansha Patel, Priyanka Agarwal, Shruti Bohra Objective: The main rationale for treatment failure and death of the patients with oral squamous cell carcinoma OSCC is loco-regional recurrence, development of second primary tumor SPT and metastasis, which could be well explained by concept of field cancerization.
Identification of patients at high condyloma acuminata literature review for development of SPT is an important part of research for cancer management. This study was designed keeping this aspect in mind and utilizing the increased expression of p53 as an indicator of existence of altered fields in mirror image biopsies of OSCC patients.
Design: Forty clinically diagnosed oral cancer patients were included in the study. Biopsy tissue samples from clinically diagnosed oral cancer patients Group A and the mirror image, clinically normal condyloma acuminata literature review mucosa at corresponding contralateral anatomical site Group B were studied for histopathological evaluation and p53 immunoexpression.
Results: Tissue alterations were observed in Groups A and B.
There was statistically significant chi-square value - Conclusions: Evidence of presence of field cancerization, evaluated by histopathological alterations and enhanced p53 expression was observed in mirror image biopsies of OSCC patients.
This could predict the altered state of oral mucosa secondary to carcinogen exposure. The realization of a genetically altered field as a cancer risk factor provides a new paradigm. It would be prudent to keep these patients under close observation and to advice them chemotherapeutic regimes. Corresponding author: Alka H.
