Leaf discs from expanding leaves of Rumex patientia L. were exposed to 7 hours of visible plus different levels of ultraviolet radiation in the 290 to 315 nm waveband (UV-B) and then placed in darkness. Leaf disc expansion was reduced and anthocyanin production was increased in discs exposed to moderate or high levels of UV-B radiation when compared to control discs. The possibility that the in...

the problem of pole assignment, also known as an eigenvalue assignment, in linear discrete-time periodic systems in discs was solved by a novel method which employs elementary similarity operations. the former methods tried to assign the points inside the unit circle while preserving the stability of the discrete time periodic system. nevertheless, now we can obtain the location of eigenvalues ...

BACKGROUND To evaluate and compare in vitro the antibacterial efficacy of five antibiotics when added individually to five endodontic sealers against Enterococcus faecalis (EF). MATERIALS & METHODS This controlled trial with systematic allocation method was carried out to detect the combined antibacterial activity of five endodontic sealers (Kerr sealer EWT, Endomethasone, AH26, AH Plus, Roek...

The present investigation was carried out to study the prevalence of bacterial pathogens responsible for subclinical mastitis in buffaloes and their antibiogram pattern to selected antibiotics. The study was carried out on lactating buffaloes maintained at the Cattle and Buffalo farm, Indian Veterinary Research Institute, Izatnagar, India. Screening for subclinical mastitis was done by Californ...

We present a case of a 51-year-old male patient hospitalized due to acute coronary syndrome requiring stent implantation to the left main stem. Double antiplatelet therapy was commenced. After 2-3 days, the patient presented with high fever, dyspnea on exertion, pain in the chest, myalgia, and general weakness. Transthoracic (TTE) and transesophageal (TEE) echocardiography revealed abnormal, tu...

Using a local model Gammie (2001) has shown that accretion discs with cooling times tcool ≤ 3Ω −1 fragment into gravitationally bound objects, while those with cooling times tcool > 3Ω −1 evolve into a quasi-steady state. We use three-dimensional smoothed particle hydrodynamic simulations of protoplanetary accretion discs to test if the local results hold globally. We find that for disc masses ...

Changes in phosphate metabolism were explored in discs from tobacco (Nicotiana tabacum) leaves of three contrasting types: green leaves which were fully expanded and attached to the plant, leaves which had yellowed following excision and dark starvation, and leaves which had yellowed while attached to the plant. 2,4-Dinitrophenol at 10(-5)m stimulated the respiration rate of discs from green an...

and clatter. The Italians call them buffone — clowns. The large white grubs feed on roots and can be a major pest of grass and potatoes. Now controlled by pesticides, they were once far more abundant locally. In 1574, adult cockchafers were so numerous in the Severn Valley that their drowned bodies blocked the wheels of watermills, the book describes. In parts of Europe, if not in Britain, the ...

BACKGROUND Campylobacter infections may lead to serious conditions, including septicemia or other invasive forms of the disease, which require rapid and accurate laboratory diagnosis and subsequently appropriate antimicrobial therapy. The aim of this study was to compare the species distribution and antimicrobial susceptibility pattern of Campylobacter spp. strains isolated from patients and fo...

The aim of this study was to determine the Lactobacillus plantarum isolated from soy milk, the antimicrobial activity of the bacteriocin produced by the isolate against the pathogenic bacteria and antibiotic resistance of these isolates.The identity of the culture was based on characteristics of the strains of Lactobacillus spp. as presented in Bergey’s Manual of Determinative Bacteriology, car...
