In the present research work three Pakistani medicinal plants were scrutinized for their antibacterial and phytotoxic potentials. The antibacterial and phytotoxic effects were determined for the crude methanolic extract and its subsequent solvent fractions. In case of antibacterial effect the chloroform and ethyl acetate fractions of all tested plants showed moderate antibacterial potential. Al...

In this study, we report the antibacterial activities of six polyphenols (i.e., luteolin, quercetin, scutellarin, apigenin, chlorogenic acid, and resveratrol) against 29 clinical isolates of methicillin-resistant Staphylococcus aureus (MRSA), and in vitro antibacterial activities of two-drug combinations. All of the MRSA strains evaluated were clinical isolates from patients with MRSA bacteremi...

We study the problem of statistically correct inference in networks whose basic representations are population codes. Population codes are ubiquitous in the brain, and involve the simultaneous act ivi ty of many units coding for some low dimensional quantity. A classic example are place cells in the rat hippocampus: these fire when the animal is at a particular place in an environment, so the u...

The increasing presence of drug-resistant bacterial infections among hospitalAbstract ised patients has resulted in greater numbers of patients receiving inappropriate antimicrobial treatment. This has led to the development of a novel paradigm guiding the administration of empirical antimicrobial therapy for patients with serious infections in the hospital setting. Antibacterial de-escalation ...

Titanium implants have been widely used for many medical applications, but bacterial infection after implant surgery remains one of the most common and intractable complications. To this end, long-term antibacterial ability of the implant surface is highly desirable to prevent implant-associated infection. In this study, a novel antibacterial coating containing a new antibacterial agent, (Z-)-4...

Fabric quality and durability are a concern with fibers that contain natural antibacterial properties or are treated to provide antibacterial properties. The textile industry has developed antibacterial fabric to address the public’s desire for improved sanitation and personal protection against disease transmission. The approach has been to attach biocidal or some bacteriostatic groups to the ...

We synthesized peptide-resin conjugates (1 and 2) by immobilizing β-sheet antibacterial peptide and α helical antibacterial peptide on PEG-PS resin, respectively. Conjugate 1 showed considerable antibacterial activity in various conditions, whereas conjugate 2 did not exhibit antibacterial activity. The growths of various bacteria were inhibited by conjugate 1 even at lower concentrations than ...

To establish the basis for the reduced expression of the X determinant on leukemic blasts and the changes in antigenic expression that occur during myeloid maturation, the presence on myeloid cells of X and related structures was examined in conjunction with studies on the activities of the glycosyltransferases involved in their biosynthesis. Expression of X and sialyl-X was weak on blasts in c...

The incidence, distribution, size, and histopathology of rat small and large bowel tumors induced by sequential administra tion of 1,2-dimethylhydrazine followed by cecal placement of one of six differing types of suture materials were systematically examined. In addition, measurements of /3-glucuronidase activi ties in large bowel contents followed by fecal trace metal deter minations were don...

We time-studied a Caterpillar 950F front-end loader and a Caterpillar 528 grapple skidder used to extract bunched whole trees to a landing in a short rotation Eucalyptus plantation. The loader was 40-60% more productive than the grapple skidder, depending on extraction distance. Alternatively, the single loader could both extract trees and handle the landing duties, such as moving residues from...
