Seaweeds are considered a potential source of antiobesity agents. Because Caulerpa, a seaweed, has been consumed for food in Japan, China, South Korea, and Australia, we hypothesized that Caulerpa okamurae may have antiobesity effects in an animal model of high-fat diet (HFD)-induced obesity in C57BL/6 mice. Herein, we found that the ethanolic extract of C okamurae (COE) significantly inhibited lipid accumulation and reduced the expression of the master regulator of adipogenesis, peroxisome proliferator-activated receptor-γ, sterol regulatory element binding protein-1c, and CCAAT/enhancer-binding protein-α in 3T3-L1 adipocytes...

Transplantation of stem cells using biocompatible nanofibrous scaffolds is a promising therapeutic method for treating Diabetic Mellitus. The aim of this study was to derive insulin-producing cells (IPCs) from conjunctiva-derived mesenchymal stem cell (CJMSCs) and to compare the functionality of differentiated IPCs in a three-dimensional (3D) culture with 2D. Furthermore, the effects of hydrophobicity of scaffold on IPCs differentiation were examined. Scanning electron microscopy (SEM), quantitative real times PCR (qPCR), Immunostaining and flow cytometry were used to analyze fabricated scaffold and the presence of IPCs...

Exposure of the inhabitants of Najran area in Saudi Arabia to the toxic elements As, Cd, Cr, and Pb through foods has not been previously investigated. Exposure to such elements is an important public health issue, so the study described here was performed with the aim of determining estimated dietary intakes (EDIs) for these metals in Najran area. The As, Cd, Cr, and Pb concentrations in four staple foods (rice, wheat, red meat, and chicken) were determined by inductively coupled plasma-mass spectrometry. A food frequency questionnaire (FFQ) was completed by 80 study participants...

An atomic emission spectrometer (AES) based on a novel atmospheric pressure liquid cathode glow discharge (LCGD) as one of the most promising miniaturized excitation sources has been developed, in which the glow discharge is produced between a needle-like Pt anode and the electrolyte (as cathode) overflowing from a quartz capillary. Lower energy consumption (<50 W) and higher excitation efficiency can be realized by point discharge of the needle-like Pt. The miniaturized LCGD seems particularly well suited to rapid and high-sensitivity determination of K, Ca, Na, and Mg in salt mines samples...

This case report describes mild anaemia and intravascular haemolysis in an otherwise healthy 41-year-old ultramarathon runner. In long-distance endurance athletes, trace gastrointestinal bleeding and plasma volume expansion are recognised sources of mild anaemia, often found incidentally. However, repetitive forceful foot striking can lead to blood cell lysis in the feet, resulting in a mild macrocytic anaemia and intravascular haemolysis, as was demonstrated in the patient described herein. Mild anaemia in runners, often called 'runner's pseudoanaemia', is typically clinically insignificant and does not require intervention...

Plastic organic scintillators such as the blue-emitting BCF-12 are versatile and inexpensive tools. Recently, BCF-12 scintillators have been foreseen for investigation of the spatial distribution of neutrons emitted from dense magnetized plasma. For this purpose, small-area (5 mm × 5 mm) detectors based on BCF-12 scintillation rods and Hamamatsu photomultiplier tubes were designed and constructed at the Institute of Nuclear Physics. They will be located inside the neutron pinhole camera of the PF-24 plasma focus device...

A structurally simple dielectric barrier discharge based mercury-free plasma UV-light source has been developed for efficient water disinfection. The source comprises of a dielectric barrier discharge arrangement between two co-axial quartz tubes with an optimized gas gap. The outer electrode is an aluminium baked foil tape arranged in a helical form with optimized pitch, while the inner electrode is a hollow aluminium metallic rod, hermetically sealed. Strong bands peaking at wavelengths 172 nm and 253 nm, along with a weak band peaking at wavelength 265 nm have been simultaneously observed due to plasma radiation from the admixture of xenon and iodine gases...

PURPOSE: Restoring skeletal muscle and hepatic glycogen content during short-term (<6 h) recovery from prolonged exercise is pertinent for athletes seeking to maximize performance in repeated exercise bouts. Previous research suggests co-ingestion of fructose-glucose carbohydrate sources augments hepatic and has equivalent effects on skeletal muscle glycogen storage during short-term recovery from prolonged exercise compared to isocaloric glucose ingestion. The aim of the present investigation was to determine if this has a discernible effect on subsequent exercise capacity...

Transfusion-independent patients with thalassemia intermedia (TI) develop fatal iron overload from excessive iron absorption triggered by ineffective erythropoiesis. More information about iron pharmacokinetics and nonheme, dietary iron absorption in such patients is needed to optimize management. To obtain more information, different forms of supplemental nonheme iron sources (ferritin and ferrous sulfate) were compared in 4 TI (hemoglobin <9 g/dL) and 6 control (hemoglobin 12-16 g/dL) patients. Serial serum iron concentrations were measured during the 24 hours following consumption of 1 mg/kg of elemental iron as ferritin or ferrous sulfate...

Cerium is the most abundant rare earth element (REE) within the waste product of alumina production (red mud), but its speciation in this complex material is still barely understood. Previous studies showed evidence for a correlation between Ce and the main constituent of red mud, iron oxides, which led us to investigate the most abundant iron oxide in red mud, hematite, as possible carrier phase for Ce. Synthetic hematite can incorporate up to 1.70±0.01wt% Ce, which leads to a systematical increase of all unit cell parameters...

Partial thickness rotator cuff tears (PTRCTs) are a common pathology among shoulder disorders in people over 50 years. Treatment of PTRCTs remains controversial. Most studies on the treatment of PTRCTs have explained surgical techniques or outcomes; few studies have centralized on the conservative and new management of PTRCTs, like treatment with Platelet-rich plasma (PRP). These case series study have been conducted on Platelet-rich plasma (PRP) injection, as a concentrated source of cytokines that can stimulate healing of soft tissue...

Severe nerve injury such as axotomy induces neuron degeneration and death of surrounding glial cells. Using a crayfish stretch receptor that consists of a single mechanoreceptor neuron enveloped by satellite glia, we showed that axotomy not only mechanically injures glial cells at the transection location, but also induces necrosis or apoptosis of satellite glial cells remote from the transection site. We studied Ca2+role in spontaneous or axotomy-induced death of remote glial cells. Stretch receptors were isolated using the original technique that kept the neuron connected to the ventral cord ganglion (control preparations)...

Plasma, formed by ionization of gas molecules or atoms, is the most abundant form of matter and consists of highly reactive physicochemical species. In the physics and chemistry fields, plasma has been extensively studied; however, the exact action mechanisms of plasma on biological systems, including cells and humans, are not well known. Recent evidence suggests that cold atmospheric plasma (CAP), which refers to plasma used in the biomedical field, may regulate diverse cellular processes, including neural differentiation...

BACKGROUND AND OBJECTIVES: Krill oil (KO) and fish oil (FO) are good sources of health-benefiting long chain n- 3 polyunsaturated fatty acids (LC n-3 PUFA), EPA and DHA. There are conflicting outcomes on the bioavailability of LC n-3 PUFA from KO compared with FO. This study investigated the postprandial incorporation of LC n- 3 PUFA into plasma lipids following consumption of 5 capsules of KO or FO in comparison with olive oil (OO) control in healthy women. METHODS AND STUDY DESIGN: 10 women (aged 18-45 years) consumed a high-fat (15 g) breakfast, supplemented with 5 g of KO, FO, or OO in a random order with a minimum seven-day washout period between the supplementations...

Exosomes and other extracellular vesicles (EVs) have been implicated as mediators of intercellular communication. Their release into the circulation has the potential to inform about tumor status. In-depth proteomic characterization of plasma-derived EVs has been limited by challenges in isolating EVs from protein-abundant biological fluids. We implemented a novel single-step density gradient flotation workflow for efficient and rapid isolation of highly enriched circulating EVs from plasma. Mass-spectrometry analysis of plasma EVs from subjects with lung adenocarcinoma and matched controls resulted in the identification of 640 proteins...

REVIEW
James W Putney
Calcium signals arise by multiple mechanisms, including mechanisms of release of intracellular stored Ca2+, and the influx of Ca2+ through channels in the plasma membrane. One mechanism that links these two sources of Ca2+ is store-operated Ca2+ entry, the most commonly encountered version of which involves the extensively studied calcium-release-activated Ca2+ (CRAC) channel. The minimal and essential molecular components of the CRAC channel are the STIM proteins that function as Ca2+ sensors in the endoplasmic reticulum, and the Orai proteins that comprise the pore forming subunits of the CRAC channel...
