BACKGROUND
Diabetes mellitus as a chronic metabolic disease occurs in patients with partial or complete deficiency of insulin secretion or disorder in action of insulin on tissue. The disease is known to provide conditions for overgrowth of Candida species. Candida spp. cause candidiasis by many
Influenza viruses cause seasonal flu each year and pandemics or epidemic sporadically, posing a major threat to public health. Recently, a new influenza D virus (IDV) was isolated from pigs and cattle. Here, we reveal that the IDV utilizes 9-O-acetylated sialic acids as its receptor for virus entry.
An esterase from S. mutans UA159, SMU_118c, was shown to hydrolyze methacrylate resin-based dental monomers.
OBJECTIVE
To investigate the association of SMU_118c to the whole cellular hydrolytic activity of S. mutans toward polymerized resin composites, and to examine how the bacterium adapts its
A carboxyl esterase (TtEst2) has been identified in a novel thermophilic bacterium, Thermogutta terrifontis from the phylum Planctomycetes and has been cloned and over-expressed in Escherichia coli. The enzyme has been characterized biochemically and shown to have activity toward small p-nitrophenyl
Whole saliva of 59 healthy persons was used for determination of esterase activity. The pattern of esterase was studied by means of isoelectrofocusing on thin-layer acrylamide gels. The esterases found in whole saliva are suggested to be derived from the cells of the tissue in the oral cavity. This
Cytotoxicity is primarily limited to the olfactory epithelium of the dorsal meatus region of the nasal cavity of rodents following inhalation exposure to acrylic monomers. To investigate the biochemical basis for this effect, three regions of the Fischer F344N rat nasal cavity were evaluated for
OBJECTIVE
Our purpose was to (1) determine the value of amniotic fluid interleukin-6 determination in the detection of microbial invasion of the amniotic cavity and (2) compare interleukin-6 to other rapid tests in the evaluation of preterm labor.
METHODS
Amniotic fluid interleukin-6 was determined
Four cases of an ulcero-proliferative lesion of putative histiocytic origin, arising in the oral cavity, are described. This lesion, which has not been defined previously, is easily confused histologically with a malignant process of lymphoid origin, thereby representing a pseudolymphomatous
An in vivo method is described showing how selective killing of macrophages in the peritoneal cavity by carrageenan affects Eimeria tenella infection in chickens. Killing of macrophages was demonstrated by the increasing loss of cytoplasmic contents under light microscopy, by the disappearance of
Methyl (R)-o-chloromandelate (R-CMM) is an intermediate for the platelet aggregation inhibitor clopidogrel. Its preparation through enzymatic resolution of the corresponding ester has been hindered by the lack of an enzyme with satisfying enantioselectivity and activity. In the present work, we
Esterase EstB from Burkholderia gladioli belongs to a novel class of esterases homologous to penicillin binding proteins, notably DD-peptidase and class C β-lactamases. It can cleave the side chain acetyl ester group from cephalosporins leaving the β-lactam ring intact, which is a feature of
143 consecutive effusion samples were stained for non-specific esterase (NSE) in order to test the diagnostic value of the staining method with reference to the diagnosis of carcinosis in pleural and peritoneal cavities. On comparing the results obtained by cytomorphological evaluation and NSE
Several lines of evidence support the view that premature rupture of the membranes and premature labor are associated with bacterial infection of the amniotic cavity. The standard method of diagnosing intraamniotic infection is amniotic fluid culture, but the results become available only after 72
