S-Adenosylmethionine (SAM) is a natural metabolite having important uses in the treatment of various diseases. To develop a simple and effective way to produce SAM, immobilized Escherichia coli cells highly expressing an engineered variant of methionine adenosyltransferase (MAT) were employed to synthesize SAM. The recombinant I303V MAT variant was successfully produced at approximately 900 mg/L in a 10-L bioreactor and exhibited significantly less product inhibition and had a four-fold higher specific activity (14...

Dietary management of autoimmune diabetes includes low glycemic foods classified from the glycemic index, but it does not consider the role that immunoreactive foods may play with the immunological etiology of the disease. We measured the reactivity of either monoclonal or polyclonal affinity-purified antibodies to insulin, insulin receptor alpha, insulin receptor beta, zinc transporter 8 (ZnT8), tyrosine phosphatase-based islet antigen 2 (IA2), and glutamic acid decarboxylase (GAD) 65 and 67 against 204 dietary proteins that are commonly consumed...

Smoking is the leading cause of preventable death and chronic diseases in the U.S. Identifying smokers and providing appropriate intervention is therefore an integral part of each clinic visit. A combination of pharmacotherapy as well as behavioral counseling provides the best results. Pharmacotherapy includes nicotine replacement (patch, gum, lozenges), bupropion and varenicline. More recently, electronic nicotinic delivery systems (such as e-cigarettes, vaporizers/vape pens, and hookah pens) have become popular...

Our ability of screening broad communities for clinically asymptomatic diseases critically drives population health. Sensory chewing gums are presented targeting the tongue as 24/7 detector allowing diagnosis by "anyone, anywhere, anytime". The chewing gum contains peptide sensors consisting of a protease cleavable linker in between a bitter substance and a microparticle. Matrix metalloproteinases in the oral cavity, as upregulated in peri-implant disease, specifically target the protease cleavable linker while chewing the gum, thereby generating bitterness for detection by the tongue...

A novel negative-stranded (ns) RNA virus associated with a severe citrus disease reported more than eighty years ago has been identified. Transmission electron microscopy showed that this novel virus, tentatively named citrus concave gum-associated virus (CCGaV), is flexuous and non-enveloped. Notwithstanding, its two genomic RNAs share structural features with members of the genus Phlebovirus, which are enveloped arthropod-transmitted viruses infecting mammals, and with a group of still unclassified phlebo-like viruses infecting prevalently arthropods...

Xanthan gum (XG) is natural polysaccharides used in food industries as stabilizers and thickener agents. The problem is that some food products are found to be contaminated by pathogenic bacteria such as Escherichia coli (E. coli) and Staphyloccus aureus (S. aureus) that reduce their shelf life. This research aims to synthesize biodegradable antibacterial XG-grafted-poly(N-vinyl imidazole) PVI and the effect of reaction parameters were studied on grafting yield (G), grafting efficiency (GE), total conversion (TC) and homopolymer (H) %...

Actinomycosis is a rare chronic disease caused by a group of anaerobic Gram-positive bacteria that colonize the mouth, colon, and urogenital tract. Infection involving the cervicofacial area is the most common clinical presentation, followed by that of the pelvic and thoracic areas. The preoperative diagnosis of abdominal actinomycosis is difficult because the condition can be easily confused with malignancy, tuberculosis, or other inflammatory diseases. We report a case of omental actinomycosis mimicking a foreign body...

Periodontitis is a chronic inflammatory disease that affects the interface of teeth and surrounding tissues. Gingival crevicular fluid (GCF) is an exudate of the periodontal tissues and can be collected from the gap between the tooth and gum (gingival sulcus or periodontal pocket) with paper strips. Testing of GCF is a low-cost and minimally invasive procedure. In a variety of diseases, microRNAs (miRNAs) in body fluids are implicated in pathogenesis, and are suggested as potential diagnostic biomarkers. Here, we profiled miRNAs in GCF (two chronic periodontitis, one aggressive periodontitis, and five healthy subjects) using miRCURY LNA™ Universal RT microRNA PCR System, which yielded quantitative measures of more than 600 miRNAs...

Severe gum disease (periodontitis), which is one of the major global oral diseases, results from microbe-host dysbiosis and dysregulated immuno-inflammatory responses. It seriously affects oral health and general wellbeing with significant socio-economic implications. It has been well documented that natural flavonoids such as baicalin (BA) and baicalein (BE) possess potent anti-inflammatory effects. However, their intrinsic poor solubility and low bioavailability severely limit their biomedical applications...
