in this study, different methods of separating of the microalgae from the culture medium as one of the most important and expensive steps in achieving commercial production of biodiesel from microalgae was investigated. electro coagulation-flotation (ecf) was preferred among these methods due to its process simplicity and capability to scale up. the effect of three parameters, i.e., initial ph,...

The body is comprised of solids and water; the proportion of water changes according to age. Total body water (TBW) is divided between the intracellular fluid (ICF) and the extracellular fluid (ECF), separated by cell membrane. The ECF can be further subdivided into water within the intravascular space (IVS) and the interstitial space (ISS), separated by capillary membrane. The biggest change i...

background: gastric cancer is an important health problem across the world. chemotherapy in combination with local treatment is standard treatment for locally advanced gastroesophageal cancers. the purpose of this investigation was evaluation of response and tolerability to neoadjuvant eox regimen in locoregionally advanced gastric cancer. materials and methods: patients with locoregionally adv...

The Bacillus subtilis gene pgsA, which codes for the phosphatidylglycerophosphate synthase that catalyzes the committed step for the synthesis of phosphatidylglycerol (PG), is essential since Pspac-pgsA cells require IPTG for growth. Removal of the inducer caused a dramatic decrease of PG content in the membranes of cells and retarded growth. At 60 min and 120 min after removal, it was reduced ...

Electrical stimulation of a trout saline-perfused trunk preparation resulted in metabolic and respiratory responses comparable to those occurring after exhaustive exercise in vivo. Recovery of intracellular acid-base status and glycogen resynthesis were faster than in vivo. Intracellular carbonic anhydrase (ICF CA) blockade elevated intracellular[Formula: see text] relative to untreated postexe...

The purpose of this study was to examine the disposition of diphenhydramine (DPHM) across the ovine blood-brain barrier (BBB). In six adult sheep, we characterized the central nervous system (CNS) pharmacokinetics of DPHM in brain extracellular fluid (ECF) and cerebrospinal fluid (CSF) using microdialysis in two experiments. In the first experiment, DPHM was administered via a five-step i.v. in...

INTRODUCTION the low prevalence of enterocutaneous fistulas (ECF) in patients with Crohn´s disease (CD) justifies the scarcity of studies that analyze the effect of medical treatment and the need for surgery in these patients. The objective of this study was to evaluate the clinical characteristics of patients with CD who have ECF and the response to different treatments. MATERIALS AND METHOD...

Extracytoplasmic function (ECF) sigma factors play a key role in the regulation of vital functions in the bacterial response to the environment. In Gram-negative bacteria, activity of these sigma factors is often controlled by cell-surface signalling (CSS), a regulatory system that also involves an outer membrane receptor and a transmembrane anti-sigma factor. To get more insight into the molec...
