Ultrasonic characterization of proteins and blood cells
Ultrasound changes its intensity and speed when propagating through a liquid or a suspension containing particles. In addition it generates a weak electric signal by altering the motion of ions and charged particles. Hence acoustic and electroacoustic measurements provide information about the properties of suspended particles and molecules. Here we present both acoustic and electroacoustic ...

Effect of maternal obesity and passive smoking on neonatal nucleated red blood cells
Passive cigarette smoking and obesity during pregnancy are risk factors for adverse outcome in infant. Elevated umbilical cord neonatal nucleated red blood cells (NRBCs) have been suggested as a marker of intrauterine foetal hypoxia. Aim to demonstrate whether maternal risk factors during pregnancy are capable of elevating circulating NRBCs measured at birth. We compared the count of NRBCs in the ...

Distribution of mercury and selenium in blood compartments of bottlenose dolphins (Tursiops truncatus) from Sarasota Bay, Florida
Total mercury and selenium concentrations ([THg], [Se]) in serum, plasma, whole blood, and packed cells were examined in a resident population of free ranging bottlenose dolphins (Tursiops truncatus) from Sarasota Bay, Florida. We determine how these elements partition in blood and assess compartment‐specific associations. Determining the distribution of Se and THg can provide physiologic ...

Microfluidic tools to investigate pathologies in the blood microcirculation
We show how microfluidics technology can be used to fabricate simple and innovative biomimetic tools to shed new light on physiopathological events occurring in the blood microcirculation. Examples of applications are given in the context of the acute respiratory distress syndrome (ARDS), an inflammatory disease of the lung triggered by a massive arrest of white blood cells in the lung ...

Protection of gastrointestinal and haematopoietic systems by ascorbic acid-2-glucoside in mice exposed to whole-body gamma radiation
Whole-body exposure of mice to gamma radiation leads to depletion of tissue antioxidant defence and damages the haematopoietic and gastrointestinal systems in mice. Administration of ascorbic acid-2-glucoside (AsAG) at a dose of 100 mg/kg body weight could prevent the radiation-induced reduction of total White Blood Cell (WBC) count and decrease in bone marrow viability following whole-body ...

Types and Function of Oligosaccharides
Types of Oligosaccharides Disaccharides These are the sugars having two monomeric units, and thus it is called di_saccharide. Some examples are maltose, sucrose, and lactose. Maltose is the action of an enzyme and it gives glucose +glucose; Sucrose (or cane sugar) in the action of invertase produces fructose + glucose, and Lactose(milk sugar) in the action of enzyme lactase produces galactose + ...

What dermatologists need to know about Bartonella
Galaxy Diagnostics co-founder Dr. Ed Breitschwerdt on ReachMD with Dr. Michael Greenberg on what dermatologists should know about Bartonella species infections. Research over the past 30 years has shown that Bartonella species infect a wide array of cell types, including red blood cells and endothelial cells (in particular cells that line the blood vessels), in both people and ...

Vanadium Distribution Following Decavanadate Administration
Abstract An acute exposure of two vanadate solutions—metavanadate and decavanadate—containing different vanadate oligomers, induces different patterns of subcellular vanadium distribution in blood plasma, red blood cells (RBC), and cardiac muscle subcellular fractions of the fish Sparus aurata (gilthead seabream). The highest amount of vanadium was found in blood plasma 1 h after (5 mM) ...

Creative Enzymes Launches Advanced Neuraminidase for Flu Vaccine Development
Creative Enzymes, a professional enzyme provider located in New York, always hammers at researches and trials in order to provide customers with various enzymes as many as possible. Last week, the product manager of Creative Enzymes announced the launch of neuraminidase, which is expected to further develop a new universal influenza vaccine. Neuraminidase is a drug target to prevent the spread ...

Transcriptional expression of H2B, CTP synthase and PLK3 genes in whole blood exposed to 60Co gamma radiation
Ionising radiation induces complex molecular responses in human cells resulting in changes at mRNA and protein expression. Limited data is available on the transcriptional status of functional genes in response to ionising radiation using peripheral blood mononuclear cells (PBMCs). In the present study, transcriptional profiles of Histone 2B, CTP synthase and PLK3 were studied. Blood samples were ...

Subacute toxicity of selenium sources in mice
Sixteen groups of mice were fed diets containing different selenium species to compare their toxicity. Inorganic sodium selenate and sodium hydroselenite, elementary nanoSe, organic Sel‐Plex, and Lacto‐MicroSelenium were administered for 14 d at concentrations of 0.5, 5, and 50 ppm Se, equivalent to 0.5, 5, and 50 mg Se/kg food, corresponding to an estimated 4, 40, and 400 µg/kg bw/d Se uptake, ...

Blood Storage and Preservation
How Is Blood Stored and Preserved? Blood storage is an important process in the blood banking industry as it helps maintain the quality of blood and its medical effectiveness. Blood can be stored in a few different ways, but the most common method is refrigeration.Blood banks depend on donors to provide blood and blood components. When blood is collected from a donor, it must be processed to ...

HPV-16 E7-Specific Cellular Immune Response
HPV-16 E7-Specific Cellular Immune Response in Women With Cervical Intraepithelial Lesion Contributes to Viral Clearance: A Cross-Sectional and Longitudinal Clinical Study High-risk human papillomavirus (HPV) infection is the cause of almost all cervical cancers. HPV16 is one of the main risk subtypes. Although screening programs have greatly reduced the prevalence of cervical cancer in ...

The response of peripheral blood mononuclear cells to shape memory alloys
The aim of this work was to study the response of human peripheral blood mononuclear cells (PB-MNCs) to Cu-Al-Ni and Ni-Ti shape memory alloys (SMAs). The alloys were prepared as rapidly solidified thin ribbons via melt spinning. It has been shown that the ribbons were non cytotoxic for PB-MNCs as determined by the viability and apoptosis assay. In 18 cultures out of 20 cultures of individual ...

Effects of trophic exposure to diclofenac and dexamethasone on hematological parameters and immune response in freshwater fish
The aim of this work was to evaluate the effects of diclofenac and dexamethasone on hematological parameters and immune response in the fish species Hoplias malabaricus after trophic exposure. Fish were fed twice every week with Astyanax sp., which was submitted to intraperitoneal (i.p.) inoculation with diclofenac (0, 0.2, 2.0, or 20.0 µg/Kg) or dexamethasone (0.03, 0.3, or 3.0 µg/Kg). After ...

New Breakthrough in Cancer Cell Research
The body's immune system is an effective weapon against disease, and immunotherapy of cancer cell research is the current frontier in the treatment of cancer and other diseases. Recently, researchers at Notre Dame University have identified specific features of the reaction of two distinct peptide antigens to a T-cell receptor (TCR), which provides new clues to optimizing molecular structure ...

Mold and chronic sinusitis
Do you suffer from frequent sinus headaches, congestion and runny nose? Have you taken enough cold and allergy medication to qualify for “frequent flier” awards? You may not have a persistent cold or allergies. Researchers at the Mayo Clinic have discovered what may be the real cause of most chronic sinus conditions: MOLD! An estimated 37 million Americans suffer from chronic sinusitis, and the ...

The 3rd AIDS patient is "cured"! Has mankind finally conquered AIDS?
At an academic conference on Feb 15, U.S. experts announced the world's first female AIDS "cure," making it the third case of HIV infection to be cured. After therapy and withdrawal of antiviral drugs, HIVs were not identified in the patient's body for more than 14 months, indicating that the virus was in complete remission, according to academics. The key to this patient's recovery was a blood ...
