International Journal of Oral and Craniofacial Science Mini Review The incidence of cancer worldwide is on a rise, accounting it to be the second most common disease, first being the coronary heart disease [1]. The losses of cellular regulation that gives rise to most or all cases of cancer are due to genetic damage. Mutations, in two broad classes of genes – proto-oncogenes (eg, ras) and tumor suppressor genes (eg, APC) – play key roles in cancer induction. These genes encode many kinds of proteins that help control cell growth and proliferation. All human tumors have inactivating mutations in genes that normally act at various cell-cycle checkpoints to stop a cell’s progress through the cell cycle if a previous step has occurred incorrectly or if DNA has been damaged [2].   http://www.peertechz.com/Oral-Craniofacial-Science/pdf/IJOCS-2-111.pdf 

Archives of Clinical Nephrology Mini Review Vitamin D presents interesting pleiotropic effects for the CKD patient (effect and anti-inflammatory properties). Patients with chronic kidney disease (CKD) have impaired endothelial function and the Vitamin D and its analogs may play a role in regulation of endothelial function and inflammation. Therefore, it is increasingly observed that CKD is characterized by a state of chronic inflammation that appears to be linked to oxidative stress, endothelial dysfunction and vascular calcification. http://www.peertechz.com/Clinical-Nephrology/pdf/ACN-1-107.pdf    

International Journal of Oral and Craniofacial Science Case Report Abstract Kaposi’s sarcoma is the malignant proliferation of the endothelial cell vessels. It is a systemic, malignant and multifactor disease. It usually presents initially as violaceous cutaneous lesions. Outside of a known context of an immune deficiency, an isolated oral lesions may not think to Kaposi’s sarcoma. Hence the interest of the histological and immunohistochemical study. This paper reviews one such case of Kaposi’s sarcoma in a 42-year-old woman who present an isolated pigmented lesions of the tongue, related to Kaposi’s sarcoma, without cutaneous or visceral involvement, and which led to the discovery of acquired immunodeficiency syndrome (HIV). The stabilization was obtained with antiretroviral triple therapy.  http://www.peertechz.com/Oral-Craniofacial-Science/pdf/IJOCS-2-110.pdf    

Global Journal of Biotechnology and Biomaterial Science Research Article Abstract  Background and Aim: Drug-induced nephrotoxicity is a renal dyfunction that arises as a result of exposure to nephrotoxic drugs. Anti-tuberculosis therapy can cause nephrotoxicity and permanent kidney damage. The current study was designed to evaluate the possible protective effects of Ruta graveolens L. leaves extract against isoniazid/rifampicin-induced nephrotoxicity in rats. Methods: The experimental rats received isoniazid and rifampicin at dose level of 50 mg/kg, and 50 or 100 mg/kg/day Ruta graveolens leaves extract orally for 45 days. http://www.peertechz.com/Biotechnology-Biomaterial-Science/pdf/GJBBS-1-105.pdf

Global Journal of Infectious Diseases and Clinical Research Review Article Current literature indicates the close relationship between root resorptions and the role of clasts responsible for hard tissue destruction. The process is complex and involves mechanical factors and intense biological activity. Immunological interactions stimulate the recruitment and migration of clasts into a specific area, in order to destroy bone, cementum and dentin. Nevertheless, understanding the whole process will bring light to other questions concerning the role of the immunologic system in other parts of the human body. http://www.peertechz.com/Infectious-Diseases/pdf/GJIDCR-2-108.pdf

Peertechz Journal of Biological Research and Development Review Article The incidence of stress among individuals submitted to major surgery is relevant. Although it has been noted that some patients go through the perioperative period without presenting stress, surgical patients have a high probability of presenting one of the four phases of stress. Recognizing the stress phase that affects the patient permits the medical team to act in a more appropriate manner and to propose interventions that will prevent worsening of the disease and an unsuccessful outcome of surgery. The main objective of this paper was to present a review of the most important aspects regarding psychic stress in patients undergoing major operations under general anesthesia. http://www.peertechz.com/Biological-Research-Development/pdf/PJBRD-1-102.pdf

We are presenting the graphical behavior of blood pressure of two patients. In both cases hypertension is present exclusively during working hours. The first graphic correspond to a 39 year old nurse working 7 hours (Figure 1) and the second one, to a 46 year old engineer working from 8:00 am to 22:00 pm. In the second case, this period also included a two hour-lunch break and nap break.  http://www.peertechz.com/Community-Medicine-Public-Health/pdf/ACMPH-2-107.pdf    

Peertechz Journal of Forensic Science and Technology Review Article Abstract  Introduction: Age estimation is essential in human identification, but also in civil and pension lawsuits. Teeth maturation is better than other structures and the dental changes provide characteristics which are grouped in different age estimation methods.  Objective: The purpose of this literature review was to present the main methods in age estimation that have been currently used.  Material and Methods: The database searched was PubMed and the terms used were “dental age estimation methods” and “forensic dentistry”. Just papers about dental age estimation methods written in English between 2012 and 2015 were selected.  Results: 67 papers were retrieved through electronic searching, but nine studies were excluded. Conclusion: The most dental age estimation methods were based on developmental stages of the teeth through radiographs and they were applied in children and sub-adults in countries of the

Journal of Dental Problems and Solutions Case Report Abstract  Premolars are recognized for their aberrant root canal anatomy. The unique feature of dilacerations and multiple root canals pose utmost challenge in the endodontic management. A clinician is required to have an insight of the morphology of tooth related to its shape, form and structure prior to commencing root canal treatment. This article describes the endodontic management of two cases of aberrant root canal anatomy in premolars.   http://www.peertechz.com/Dental-Problems-Solutions/pdf/JDPS-3-125.pdf 

Archives of Otolaryngology and Rhinology Case Report Abstract  Adenocarcinoma of the ceruminous glands is a rare malignancy arising from the glands of the external auditory canal. In most patients it is usually diagnosed as locally advanced disease with a major obstacle for radical surgery. Here, we describe two cases of patients suffering of sudden hearing loss and ipsilateral facial hemiparesis due to tumors arising from the ceruminous glands with primary intracranial involvement and subsequent middle ear infiltration. The patient with localadvanced disease underwent surgery followed by adjuvant treatment, whereas the other patient with advanced disease only to palliative therapy. However, both of them received volumetric-modulated arc radiotherapy (VMAT) resulting in complete remission as adjuvant treatment in the first patients while extending the survival as palliation in the second one. Thus, VMAT appears a suggested approach in this tumor which management is still poorly def

Journal of Novel Physiotherapy and Physical Rehabilitation Editorial The determination of functional capacity is of fundamental importance in monitoring and defining the prognosis of patients with heart failure (HF) may be the six minute walk test (6MWT) is a possibility. The 6MWT was first described by Balke in 1963 [1], since now applied in various clinical conditions, but still without proper standardization. In 2002, the American Thoracic Society (ATS) has established a guideline for performing the 6MWT [2].   http://www.peertechz.com/Novel-Physiotherapy-Physical-Rehabilitation/pdf/JNPPR-2-128.pdf

Open Journal of Environmental Biology Research Article Abstract  Heavy metals are a significant problem in municipal wastewater, in soil accumulation and are costly to remove in order to facilitate water use in irrigation. Wastewater, with three heavy metal cations and an iron, was employed in irrigation during the Sorghum bicolor (L) Moench growth period. Results show that the absorption coefficient or bioaccumulation ability of Sorghum bicolor (L) Moench is relegated to certain heavy metals and their concentrations, but not at all to plant tissues in dry ash weight (DAW) scale. Heavy metals absorption was determined in the following order: cadmium = lead > arsenic, and while tissue accumulation based on DAW was equal for cadmium and lead, based on dry weight (DW) all three ions differed. The soil’s ability to accumulate heavy metal ranked as follows: cadmium > lead > arsenic by wastewater quality in this experimvent. These results change many previous ideas about decreas

Global Journal of Biotechnology and Biomaterial Science Research Article Abstract  Bioactive ceramic materials have been under research as bone substitute for several decades. To repair the high-load bearing bones, mainly cortical bones, there is a need for the substitute to possess comparable mechanical strength to cortical bone, of which the compressive strength ranges between 100 and 230 MPa. Two prevailing bone repairing material, β-tricalcium phosphate (β-TCP, β-Ca3 (PO4 )2 ) and hydroxyapatite (HAp: Ca10(PO4 )6 (OH)2 ) have been widely researched and sintered into dense blocks to meet the mechanical requirements. α-tricalcium phosphate (α-TCP, α-Ca3 (PO4 )2 ), a high temperature polymorph of β-TCP, received relatively less attention and α-TCP dense sintered blocks have not been reported yet. In this research, we fabricated α-TCP dense blocks by sintering under various temperatures (1150-1400 °C) and the highest compressive strength was around 230 MPa. Intermediate porous b

Journal of Clinical Microbiology and Biochemical Technology Case Report Abstract  Hepatopulmonary syndrome (HPS) and portopulmonary hypertension (POPH) are the most common pulmonary vascular complications in patients with liver disease. We present a 71-year old woman with alcoholic cirrhosis and 6 month history of progressive shortness of breath with mild hypoxemia at rest. Results of spirometry was normal and diffusing capacity of the lung for carbon monoxide (DLCO) was severity reduced. Echocardiography with contrast enhancement revealed extra cardiac shunt. Three months after her initial presentation, a new echocardiography was performed with pulmonary systolic pressure increased and in a right heart catheterization (RHC) the mean pulmonary arterial pressure (PAPm) was 50 mmHg, this evidence supported the diagnosis of severe portopulmonary hypertension after HPS. http://www.peertechz.com/Clinical-Microbiology-Biochemical-Technology/pdf/JCMBT-2-107.pdf

Peertechz Journal of Environmental Science and Toxicology Short Communication Abstract  Vitamin D deficiency is a global health problem. The extent of vitamin D deficiency varies with latitude, season and sun exposure. Also the degree to which the body of religious or cultural reasons is covered, the skin color and, not least, dietary habits and the use of supplements has an impact on the vitamin D status. Women are more prone to develop vitamin D deficiency than men.   http://www.peertechz.com/Environmental-Science-Toxicology/pdf/PJEST-1-104.pdf
