Sugarcane (Saccharum officinarum L.) is a multipurpose and commercial crop of Pakistan. Sugar for food remains the most important product of sugarcane, by-products of the crop, many of them from fiber, are a significant part of its economic production. Sucrose serves as the major form of carbohydrate storage in sugarcane. Metabolism of sucrose, a mobile source of energy and carbon, is an absolu...

The distribution patterns of flavonoids and cyclohexenyl chalcone derivatives in conventional propagated (CP) and in vitro-derived (CPA) field-grown plants of an important medicinal ginger, Boesenbergia rotunda, are described. A total of eight compounds were extracted from six organs (rootlet, rhizome, shoot base, maroon stem, stalk, and leaf) of the CP and CPA plants. Five major chromatographi...

A shortage of donor organs and increasing dependence on marginal grafts with prolonged ischemic times have meant that new methods are needed to prevent postischemic damage. Herein is reported a new strategy aimed to protect donor kidney from complement-mediated postischemic damage and therefore increase the number of successful transplants. Rat donor kidneys were perfused with a membrane-locali...

The treatment of organ failure on patients requires the transplantation of functional organs, from donors. Over time, the methodology of transplantation was improved by the development of organ preservation solutions. The storage of organs in preservation solutions is followed by the ischemia of the organ, resulting in a shortage of oxygen and nutrients, which damage the tissues. When the organ...

The hepatic and splenic storage iron, including the relative distribution between ferritin and haemosiderin, was estimated in 130 necropsies including normal accident cases and cases with a variety of diseases. The storage iron was also examined histochemically. It was found that in the normal subjects, on the average, approximately 400 mg. of iron was stored in these two organs, somewhat more ...

PurposeExtracorporeal organ perfusion promises to substantially increase the use of donor organs. The TransMedics Organ Care System Heart (OCS) has received FDA approval for in expanded criteria donation after brain death (DBD) and circulatory (DCD). OHP Registry aims document post-approval practices outcomes.MethodsWe examined a contemporary observational multi-center registry transplant recip...

Female sperm storage is common among organisms with internal fertilization. It is important for extended fertility and, in cases of multiple mating, for sperm competition. The physiological mechanisms by which females store and manage stored sperm are poorly understood. Here, we report that the biogenic amines tyramine (TA) and octopamine (OA) in Drosophila melanogaster females play essential r...

INTRODUCTION Currently, the gold standard for donor organ preservation in clinical organ transplantation consists of 3 plastic bags and an ice box. The first plastic bag includes the organ itself immersed in preservation solution (e.g. Celsior). This bag is put in a second bag filled with saline, and then these two are put in a third bag filled with saline which is then put in the ice box.  The...

How sperm from competing males are used to fertilize eggs is poorly understood yet has important implications for postcopulatory sexual selection. Sperm may be used in direct proportion to their numerical representation within the fertilization set or with a bias toward one male over another. Previous theoretical treatments have assumed a single sperm-storage organ, but many taxa possess multip...

The substrate supply system for respiration of the shoot and root of perennial ryegrass (Lolium perenne) was characterized in terms of component pools and the pools' functional properties: size, half-life, and contribution to respiration of the root and shoot. These investigations were performed with perennial ryegrass growing in constant conditions with continuous light. Plants were labeled wi...
