Most hospital-acquired infections arise from colonising bacteria. Intensive care patients and immunocompromised individuals are at highest risk for microbial invasion and subsequent infection due to multiple invasive procedures in addition to frequent application of chemotherapeutics and presence of poor microperfusion leading to mucosal disruption. In this narrative review, we summarise the li...

A crude polysaccharide-protein complex from Lactarius deliciosus fruit bodies (LDP) was extracted with hot water, precipitated, and washed with 95% ethanol. After protein removal according to the Sevag method, LDP was dialyzed against running tap water and distilled water, and further purified by Sephadex G-100 column chromatography. Gas chromatography showed that LDP is composed of glucose, ga...

The most common causes of death in neonatal period is infection (32%) followed by birth asphyxia (29%) and prematurity (24%).Neonatal infections currently cause 1.6 million deaths in developing countries (Choudhury et al., 2007). Multidrug resistant Gram negative bacilli belonging to the family Enterobacteriaceae have been increasingly responsible for infections among the neonates admitted to t...

ß-Cyclodextrin (ß-CD) solubilizes stickies from deinked pulp, commercial adhesive formulations, or magazine inserts, which demonstrates its potential as a washing aid. A new test to simulate coater scratches is described; it involves scraping the test paper sample across the surface of a thin layer chromatography plate and measuring the degree of scratching on the plate. Scratching was signific...

Objective: Several studies have shown that the adult pancreas possesses a limited potential for ß– cell regeneration upon tissue injury. One of the difficulties in studying ß-cell regeneration has been the lack of a robust, synchronized animal model system that would allow controlled regulation of ß−cell loss and subsequent proliferation in adult pancreas. Research Design and Methods: Here we p...

für die resultierende mittlere Geschwindigkeit eines Teilchens nach einem Stoß: t>red = v c p . Aus den Gesetzen des elastischen Stoßes für Kugeln der Massen m0, mx ergibt sich für die Geschwindigkeit von 77i0 nach dem Stoß mit ß = ( (m x m0 ) / (m, + m 0 ) ) 2, e=(l/ß-l) (d/R0)2 : v=v0(ßey*(( 1 + 1/fi) — cos2 ft)1'*; (A.6) cos #m i n = (1 (R0/d)2 (ß (vmJv 0)2)/ (ß-1) cos # m a x = (1 (R0/d)2)1...

Due to the asymmetry introduced by the hypothesis (2), the above theorem leaves open the case where ß >ct. Actually, the entire theorem as it stands holds without hypothesis (3). This results from the fact that Erdös' proof of the theorem given in [l ] uses only the condition a>ß/2. In the contrary case, 2a=/3, if we let ai be any fixed integer of A, the set {ö+cti}, b^B, has asymptotic density...

BACKGROUND ß-Adrenergic receptor antagonists (beta-blockers) are frequently used with the aim of reducing perioperative myocardial ischemia and infarction. However, randomized clinical trials specifically designed to evaluate the effects of beta-blockers on mortality in patients undergoing non-cardiac surgery have yielded conflicting results. OBJECTIVE This study aimed to examine the effect o...

The theorem about primitive divisors in algebraic number fields is generalized in the following manner. Let A, B be algebraic integers, (A, B) = 1 , AB ^ 0, A/B not a root of unity, and Çk a primitive root of unity of order k . For all sufficiently large n , the number A" C,kB" has a prime ideal factor that does not divide Am £,'kBm for arbitrary m < n and j < k . The analogue of Zsigmondy's th...

Segmental mandibulectomy leads to a great deÞ cit in the form and function of the patient. Vascularised bone ß aps have become the choice of the method of reconstruction of the mandible in an oncologic setting. Fibula osseous or oseteocutaneous ß aps have become the favored method in centers across the world. This article reviews certain pertinent and practical points with regards to Þ bula ß a...
