tetracyclines are broad spectrum antibiotics which are inexpensive and widely available and have an appropriate safety profile. in addition to antibiotical effects, tetracyclines can inhibit matrix metaloproteinase and collagenase, and subsequently reduce inflammation, angiogenesis, and neovascularization. they have partial neuro-protective, anti-apoptotic and antioxidant properties. given thes...

Periodontal pockets act as a natural reservoir filled with gingival crevicular fluid for the controlled release of antimicrobials directly. This work reflects present status nonsurgical local intrapocket delivery in treatment periodontitis. These sites have specialty terms anatomy, permeability and their ability to retain system desired length time. A number antimicrobial products composition s...

OBJECTIVE The purpose of this study was to evaluate the effect of single and combined use of ethylenediamine tetra acetic acid (EDTA), ethylene glycol bis [b-aminoethylether] N,N,N',N'-tetraacetic acid (EGTA), EDTA plus Cetavlon (EDTAC), tetracycline-HCl, and NaOCl on the microhardness of root canal dentin. STUDY DESIGN The crowns of 30 single-rooted human teeth were discarded at the cementoe...

A neutral mononuclear Fe(II) complex with spin crossover (SCO) properties, Fe2(SCN)2 (1) (L = 2-(2-(trifluoromethyl)phenyl)-1H-imidazo[4,5-f][1,10]phenanthroline), was solvothermally synthesized. It displays a new example of two-step SCO with Tc1↓ = 250 K, Tc1↑ = 260 K and Tc2 = 295 K.

Tofu is a food product that easily contaminated by microbial due to its water content. Some bacteria usually grow in tofu are Escherichia coli, Bacillus cereus, or Staphylococcus aureus. Preservatives added solve the common storage problem. However, some manufacturers use hazardous substances, such as formalin other chemical preservative. Tiwai onion (Sisyrinchium palmifolium L.) plant grows Bo...

Hairy-cell leukemia (HCL) is a rare hematologic malignancy. HCL diagnosis can be difficult and the variant form of HCL (HCL-V) has similarities with B-cell prolymphocytic leukemia or splenic marginal zone lymphoma. We describe the different features of HCL, particularly typical HCL (HCL-C) and HCL-V. HCL prognosis was transformed by the introduction of purine nucleoside analogues such as Cladri...

conclusions the high prevalence of tet (o) resistance gene along with new detection of tet (a) resistance gene in campylobacter spp. isolated from poultry carcasses revealed an extensive tetracycline resistance among campylobacter isolates from poultry in iran. it emphasized the need for cautious use of tetracycline in poultry production to decrease the extension of tetracycline-resistant campy...

six mixed-breed apparently healthy dogs were intravenously administered a single dose of tetracycline hydrochloride (50 mg/kg) to evaluate the pharmacokinetic parameters of the drug. blood samples were collected before and at various time intervals after the administration of the drug. serum tetracycline concentrations were determined over a 24 h period using fluorescence spectrophotometry. non...

Skin disease was a that attacked the surface of body, and caused by various agents, one bacteria. One plants had antibacterial activity jengkol leaf (Archidendron pauciflorum Benth.) I.C. Nielsen because it contained compounds properties previously been studied other researchers against Staphylococcus aureus Escherichia coli So researcher interested in researching on leaves epidermidis Propioni...

Tetracycline uptake into inverted membrane vesicles from Tn10-bearing Escherichia coli cells required divalent cations. The degree of the stimulation of tetracycline uptake by various divalent cations showed the following decreasing order: Co2+ greater than Mn2+ greater than Mg2+ greater than Cd2+ greater than Ca2+. This order is consistent with the increasing order of the dissociation constant...
