Do cancer genetic lesions know enough about the genetic involvement in laryngeal cancer susceptibility and prognostic outcome? Corina Iulia Cornean, Marcel Cosgarea, Andreea Catana, Carmen Aurelia Mogoanta, Violeta Necula, Alma Aurelia Maniu Introduction: Advances in molecular biology have opened the door to a wide range of research material through the usage of genetic testing on certain variables within the human genome known as single-nucleotide polymorphisms SNPs.
The purpose of this article is to present a review on the influence variants within SNPs have on the outcome of laryngeal cancer when associated with different variables, such as external toxins or survival rate.
Amongst these toxins, the most frequent and most studied have been alcohol and tobacco consumption, with a proven increased rate of overall cancer risk within the aero-digestive tract. Materials and Methods: The review was realized utilizing available studies on cancer genetic lesions subject of genetic polymorphisms analysis of deoxyribonucleic acid DNA samples using polymerase chain reaction PCR assays and laryngeal cancer published in the PubMed database. Results: Statistical analysis of polymorphisms shows a predominantly positive association between two genetic variants of the human genome mutant homozygote and heterozygote and cancer risk with significant influence on patient outcome and survival.
Genotype combinations were divided into two categories depending on the individual at risk and protective allele within the loci of each inherited gene block. Amongst the genes involved with aero-digestive cancers, the most studied were those belonging to the xenobiotic metabolism, nucleotide excision repair NER and DNA repair pathways.
The presence of toxins has a distinct cumulative effect within the genotype-phenotype relationship, which further influences the presence of malignancy depending on the adaptability of each individual genome. Conclusions: Laryngeal cancer evolution is linked to inherited risk factors found within the genetic code. Most studied were the genes belonging to NER pathways, DNA repair and cancer genetic lesions metabolism, which all favored mutant homozygote and heterozygote variants, as high risk factors.

Only cura detoxifiere ficat cu sare amara articles focused on overall survival rates with insufficient results to undisputedly predict the risk variants.
The consumption of external toxins has a positive effect on the overall cancer risk in consumers. Most articles affirmed further evaluation or replication was needed in a larger scale population to conclusively validate their cancer genetic lesions. PDF cancer genetic lesions.
The heritable MTC results from a germline mutation in the rearranged during transfection RET proto-oncogene and is included into the multiple endocrine neoplasia 2 MEN2being associated with other endocrine abnormalities and clinical features. MTC is a neuroendocrine tumor that releases a wide range of secretory products that are responsible for a variety of symptoms, making it difficult to be diagnosed.
For this reason, the pathological analysis is of vital importance to ensure that the correct diagnosis is made. This review presents the main data from the contemporary literature related to the pathological diagnosis of a patient with MTC and highlights the wide range of tumor cytological features, the many histological variants, as well as the cancer genetic lesions tumor immunophenotype.
Antiplatelet therapy in secondary ischemic stroke prevention - a short review Cristina Florescu, Edme Roxana Mustafa, Elena-Anca Tartea, Diana-Ruxandra Florescu, Valeria-Carmen Albu Platelets play an essential role in atherothrombosis and for this reason they are the primary target of antithrombotic therapy in ischemic stroke.
Cancer biology part 5 Genes associated with cancer
We discussed here the evidence for efficacy and safety of current knowledge in antiplatelet therapy for stroke prevention after an acute ischemic stroke or transient ischemic attack. After cancer genetic lesions acute episode, long-term antithrombotic therapy is essential for the secondary prevention of stroke recurrence and complications.
These are aspirin, clopidogrel and dipyridamole.
All of these antiplatelet therapies, besides inhibiting acute arterial thrombosis, also interfere with physiological hemostasis. In cancer genetic lesions, we can say that current recommendations focused primarily on the therapy with aspirin for the secondary prevention of stroke in patients that presented vascular events, such as ischemic stroke of non-cardioembolic cause or transient ischemic attack and, as appropriate, aspirin plus dipyridamol or clopidogrel. The new therapy with ticagrelor in secondary stroke prevention seems to be promising, but more randomized clinical trials are needed to accurately assess the safety and efficacy of this new antiplatelet drug.
Current understanding of psycho-neurobiology in depressive disorders with suicidal thoughts cancer cancer genetic lesions lesions translational models Eduard Nicusor Bondoc, Dragos Marinescu, Ileana Marinescu, Ramona Denise Malin, Liliana Stanca, Roxana Eugenia Zavoi Epidemiological data confirm the rising incidence of depression associated with suicidal ideation and cardiovascular comorbidities of coronary type.
In contradiction with the large number of antidepressant drugs, the therapeutic results are not satisfactory, with numerous existing incomplete remissions characterized by maintained cellular dysfunctionalities that amplify the cognitive deterioration and the risk of several somatic comorbidities.

The surprising fact is the relatively high number of deaths in this type of patients due to acute coronary disease myocardial infarction - MI. The vulnerability of hippocampal and frontal cortex cerebral structures is presented as obtained on animal model consecutive to hypothalamic-pituitary-adrenal HPA axis hyperactivity and on theoretical model where the hypothalamic disconnectivity determines the activation in the sympathetic autonomic nervous system, leading to heart disorders: high blood pressure, left ventricular hypertrophy cancer genetic lesions coronary illness.
Identifying the association of psychological risk factors, patients fitting in a model of psychosomatic dominant personality traits, where the main risk factors are represented by inflexibility, guilt and self-accusation feelings, associated with increase of biological indicators proinflammatory factors, endothelial dysfunction and cytokine aggressiveness and neuroimaging indicators frontal, temporal, hippocampal atrophy, ventriculomegaly, cerebellum atrophy.
Changes identified post-mortem in the arterioles from the frontal cortex were found also in the coronary vessels, suggesting a symmetric evolution The highlighted personality factors are responsible for the decrease of adherence and compliance both in the psychiatric and the cardiologic treatment, the patient being exposed to behavioral risks regarding life style and nutrition, factors that increase the risk for acute coronary accident.
The psycho-neurobiological inspired theoretical models argument the importance of a differentiated and customized approach of the patients with depressive disorder and suicidal ideation, and they can be the base for initiating strategies for prevention of unfavorable evolution and risk of death by MI. Due to the rich oro-maxillofacial vasculature and the fact that some dental procedures may cause a bleeding, the physician should be able to correlate this risk with the hemorrhagic risk.
Dental procedures are a trigger for psychic stress.
