Periodontal disease, is the most prevalent inflammatory affliction characterized by the loss of supporting structures of the teeth. Although bacteria are identified as prime agents initiating the disease, but major part of tissue destruction is driven by the host immune response to infecting agent and is responsible for the clinical presentation of the disease. Porphyromonas gingivalis (P. gingivalis) has been identified as main microb Read More

Objectives: Investigation of osteoblastic responses to oxidative stress, induced by C-reactive protein (CRP) and IL-6 and ameliorating effects of doxycycline (Dox); using assays for 5-alpha dihydrotestosterone (DHT) as an antioxidant marker of healing. IL-6 and CRP are risk markers of periodontitis and prevalent comorbidities in periodontitis subjects. Methods: Confluent monolayer cultures of osteoblasts were incubated Read More

Giardia lamblia mitosomes are believed to be vestigial mitochondria which lack a genome. Similar to higher eukaryotes, mitosomal proteins possess either N-terminal or internal mitosomal targeting sequences. To date, some components of the higher eukaryote archetypal mitochondrial protein import apparatus have been identified and characterized in Giardia mitosomes; therefore, it is expected that mitochondrial sign Read More

Trypanosomatids parasites have complex life cycles which involve a wide diversity of milieus with very different physicochemical properties. Arginine kinase is one of the key enzymes, responsible for the parasites’ metabolic plasticity, which maintains the cell energy homeostasis during environment changes. Arginine kinase catalyzes the reversible phosphorylation between phosphoarginine and ADP. The phosphagen ph Read More

A novel coronavirus (MERS-CoV) related to SARS-CoV recently emerged in the Middle East causing more than 400 deaths with a mortality rate of about 30%, much higher than SARS-CoV. Both viruses target epithelial cells in the respiratory tract, although utilizing different cellular receptors. Because of the sporadic nature of the MERS outbreak and difficulty in collecting randomized, controlled clinical data, the objective of thi Read More

This is a case series describing an outbreak of VRSA/VISA associated infections in orthopedic related procedures that occurred on a medical mission trip in Antigua, Guatemala. The paper describes the clinical features, microbiology and treatment options available to treat such infections in a Third World country. It also highlights the difficulty in making an accurate diagnosis with suboptimal microbiological support.

Viperidae snakes venoms represent a source of efficient bioactive components that have already led to the development of several new drugs. In this work, we analyzed the protein content of the Montivipera bornmuelleri crude venom using LC-ESI-MS, sephadex G-75 gel filtration and SDS-PAGE and demonstrated the presence of proteins with molecular masses corresponding to metalloprotease III, serine-protease and PLA Read More

Leishmaniasis is a complex protozoan disease comprising a wide range of clinical manifestations that is usually divided into visceral leishmaniasis, cutaneous leishmaniasis, and muco-cutaneous leishmaniasis depending on leishmania parasite species and host's immune system responses. Most of the drugs produced for the treatment of leishmaniasis, from the first used to the most recently accepted, are toxic, resistance issues Read More

Viral disease is a calamity which absolutely can not be ignored for human health. The emergence of drug resistance and spread of new virus will be the new challenge against viral disease. To find and develop new antivirus agents with properties of safety, significant effect and low toxicity is the pressing question facing humans today. Because of its advantages, including rich resources, low price, less adverse effect, Traditional Ch Read More
