Interacting populations affecting proliferation of leukemic cells in culture. (1/32)

Peripheral blood cells from three patients with acute leukemic have been studied using a suspension culture method previously described.1 Cytogenetic studies in two of the patients permitted the identification of the proliferating cells in the cultures as being derived from a leukemic population. Cell separation studies using velocity sedimentation supported the concept that growth of the leukemic cells in culture is dependent on an interaction between two populations of leukemic cells.  (+info)

Permeability of squid axon membrane to various ions. (3/32)

The permeability of the squid axon membrane was determined by the use of radioisotopes of Na, K, Ca, Cs, and Br. Effluxes of these isotopes were measured mainly by the method of intracellular injection. Measurements of influxes were carried out under continuous intracellular perfusion with an isotonic solution of potassium sulfate. The Na permeability of the resting (excitable) axonal membrane was found to be roughly equal to the K permeability. The permeability to anion was far smaller than that to cations. It is emphasized that the axonal membrane has properties of a cation exchanger. The physicochemical nature of the "two stable states" of the excitable membrane is discussed on the basis of ion exchange isotherms.  (+info)

EFFECT OF CHLOROTHIAZIDE ON CESIUM-137 EXCRETION IN HUMAN SUBJECTS. (4/32)

The therapeutic value of the diuretic, chlorothiazide (Diuril), in reducing the body burden of cesium-137 in human subjects was investigated. Two subjects were given chlorothiazide, 2 g./day, following a single oral intake of cesium-137. The urinary excretion and the per cent retention of cesium-137 were compared with similar data obtained from two control subjects. Although chlorothiazide produced a marked potassium diuresis, it had no significant effect in reducing the body burden of cesium.Analysis was made of the rate of turnover of cesium and potassium in the two control subjects, who were followed up for 320 days. The biological half-lives, T(b), of K were 42 and 41 days. In both subjects a small fraction of the cesium-137 was rapidly excreted. The remainder (88% and 83% in the two cases) was excreted at a slower constant rate. The concentrations further decreased to 44% and 41.5% in 90 and 155 days, respectively.  (+info)

Cs + ADC in rat brain decreases markedly at death. (5/32)

Spectroscopic resolution of intracellular and extracellular compartments can be used to probe the kinetic environment of those spaces and the compartment-specific changes that occur following injury. This is important for understanding the biophysical mechanisms that underlie the remarkable diffusion-weighted MRI contrast of injured central nervous system (CNS) tissue. Cesium-133 is a physiologic analog of potassium that is actively taken up by cells and resides primarily in the intracellular space. The (133)Cs(+) signal can, thus, be exploited to probe the kinetic environment of the intracellular space. Two principal (133)Cs(+) resonances were observed at 11.74 T. These resonances arise separately from (133)Cs(+) in brain and temporalis muscle. The apparent diffusion coefficient (ADC) of Cs(+) in brain decreased from 1.0 +/- 0.2 microm(2)/ms in healthy tissue to 0.24 +/- 0.04 microm(2)/ms following global ischemia (average ADC +/- average uncertainty), while there was no significant change in the ADC of Cs(+) in temporalis muscle after injury. This finding underscores the tissue-specific nature of the decrease in ADC that accompanies brain injury. Further, as the Cs(+) ADC should reflect water ADC in the intracellular space, these results strongly support the hypothesis that the decrease in water ADC associated with CNS injury arises largely from kinetic changes taking place in the intracellular space.  (+info)

Direct enzymatic repair of deoxyribonucleic acid single-strand breaks in dormant spores. (8/32)

With the alkaline sucrose gradient centrifugation method, it was found that dormant spores of Clostridium botulinum subjected to 300 krads of gamma radiation showed a distinct decrease in deoxyribonucleic acid (DNA) fragment size, indicating induction of single-strand breaks (SSB). A two- to threefold difference in radiation resistance of spores of two strains of C. botulinum, 33A (37% survival dose [D(37)] = 110 krads) and 51B (D(37) = 47 krads), was accompanied by relatively larger DNA fragments (molecular weight 7.9 x 10(7)) obtained during extraction from the radiation-resistant strain 33A and smaller DNA fragments (molecular weight 1.8 x 10(7)) obtained under identical conditions from radiation-sensitive strain 51B. The apparent number of DNA SSB produced by 300 krads in strains 33A and 51B was 0.37 and 3.50, respectively, per 10(8) daltons of DNA. Addition of 0.02 M ethylenediaminetetraacetic acid (EDTA) to spore suspensions during irradiation doubled the apparent number of SSB in strain 33A but had no effect on strain 51B. In vivo, 0.02 M EDTA present during irradiation to 100 to 300 krads decreased survival of spores of 33A by about 30% but had little or no effect on 51B. Survival of 33A was also reduced by about 45% when the spores were irradiated while frozen in dry ice (-75 C) and, after irradiation, immediately exposed to 0.03 M EDTA for 1 h to inhibit repair in the dormant spores. These results suggest that the highly radiation-resistant strain 33A may be able to accomplish repair of SSB during irradiation or after irradiation under nonphysiological conditions, i.e., in the dormant state. This repair can be inhibited by EDTA. Sedimentation patterns show that DNA from spores of both strains 33A and 51B did not show any postirradiation repair during the first 6 h of germination, as opposed to Bacillus subtilis spores, which exhibit repair immediately after germination. These observations suggest the existence of direct repair in physiological dormant spores of strain 33A in the cryptobiotic resting state in the absence of germination. The repair seems to be similar to that of polynucleotide ligase activity shown to be operative in some vegetative cells. Apparently radiation-sensitive strains such as 51B and B. subtilis are generally poor in DNA repair enzyme activity under conditions of spore dormancy, which may account for the approximately threefold difference in radiation sensitivity or DNA fragility of different strains, or both.  (+info)

In Chinese medical form, Chinese medicine is widely used in the treatment of various kidney diseases. In addition, many natural treatments have been developed based on Chinese medicine. And the therapy of purifying toxins from the blood takes on the best effects, helping patients reduce high levels of creatinine. From many years of clinical experience, if waste products and toxins are eliminated from the body, firstly, patients can often act better than those who do not eliminate waste products, since toxins in the blood not only cause additional damage to kidney and tissue cells , and also affect the effectiveness of drugs for the treatment of the kidneys. Because the toxins deposited in the blood not only cause additional damage to the kidney function, but also affect the effectiveness of treatment of kidney drugs. Therefore, this treatment mainly uses medicinal herbs that help patients to isolate products from waste and toxic substances. When using herbal medicines, various natural products ...

Oxidative stress plays an important role in aging-related neurodegeneration. This study used littermates of WT and Nox2-knockout (Nox2KO) mice plus endothelial cell-specific human Nox2 overexpression-transgenic (HuNox2Tg) mice to investigate Nox2-derived ROS in brain aging. Compared with young WT mice (3-4 months), aging WT mice (20-22 months) had obvious metabolic disorders and loss of locomotor activity. Aging WT brains had high levels of angiotensin II (Ang II) and ROS production; activation of ERK1/2, p53, and γH2AX; and losses of capillaries and neurons. However, these abnormalities were markedly reduced in aging Nox2KO brains. HuNox2Tg brains at middle age (11-12 months) already had high levels of ROS production and activation of stress signaling pathways similar to those found in aging WT brains. The mechanism of Ang II-induced endothelial Nox2 activation in capillary damage was examined using primary brain microvascular endothelial cells. The clinical significance of Nox2-derived ROS in ...

Contaminants Released, Chernobyl. A retrospective view of the Chernobyl accident of Apr 26, 1986 assesses the total radiation release at about 100 megaCuries or 4 x 1018 becquerels, including some 2.5 MCi of cesium-137. The cesium is the most serious release in terms of long term consequences. The total release was around 4% of the total accumulated activity of the core and compares to a release of 15 Ci at Three Mile Island. The release was then about 7 million times that at TMI. Anspaugh, et al. suggest that essentially all the noble gases and about half of the volatile elements (iodine-131, cesium-134 and cesium-137) were released. The cesium release from all of the atmospheric weapons tests is estimated to be about 30 MCi. The noble gas releases were estimated by Levi to be 45 MCi of xenon-133 and 5 MCi of krypton-85. About 3-5% of the core inventory of the relatively refractory elements such a strontium, plutonium, and ruthenium were released, much more than from a light water reactor ...

Patients with brain metastases from lung cancer have poor prognoses and short survival time, and they are often excluded from clinical trials. Whole-cranial irradiation is considered to be the standard treatment, but its efficacy is not satisfactory. The purpose of this phase II clinical trial was to evaluate the preliminary efficacy and safety of the treatment of whole-brain irradiation plus three-dimensional conformal boost combined with concurrent topotecan for the patients with brain metastases from lung cancer. Patients with brain metastasis from lung cancer received concurrent chemotherapy and radiotherapy: conventional fractionated whole-brain irradiation, 2 fields/time, 1 fraction/day, 2 Gy/fraction, 5 times/week, and DT 40 Gy/20 fractions; for the patients with ≤ 3 lesions with diameter ≥ 2 cm, a three-dimensional (3-D) conformal localised boost was given to increase the dosage to 56-60 Gy; and during radiotherapy, concurrent chemotherapy with topotecan was given (the chemoradiotherapy

TY - JOUR. T1 - Cation effects on cell shape.. AU - Sheetz, Michael. PY - 1977/12/1. Y1 - 1977/12/1. N2 - We have found that human erythrocyte ghosts in 10 mM HEPES (pH 7.0) at 0 degrees C would crenate when 20-50 mM of Na+ or K+, 0.2-0.5 mM OF Ca++, Ba++, Sr++, or Mg++, or 10 muM of La+++ was added. The shape change after cation addition was faster than fixation by 1% glutaraldehyde at 4 degrees C and was readily reversible upon dilution of the cation. After incubation of ghosts in 10 mM HEPES (pH 7.0) at 37 degrees for 10-20 min there was a significant inhibition of subsequent crenation by cations. In a process that is believed to occur by a similar mechanism, whole red blood cells were observed to cup (invaginate) when 20 mM of a divalent or 0.1 mM of a trivalent cation was added. After neuraminidase treatment to remove the sialic acid charge groups, these same shape changes were observed in ghosts and whole cells. Another type of cation-induced crenation was found to follow upon the addition ...

Radioactive iodine-131 readings taken from seawater near the water intake of the Fukushima No. 1 nuclear plants No. 2 reactor reached 7.5 million times the legal limit, Tokyo Electric Power Co. admitted Tuesday.. The sample that yielded the high reading was taken Saturday, before Tepco announced Monday it would start releasing radioactive water into the sea [see this for background], and experts fear the contamination may spread well beyond Japans shores to affect seafood overseas.. The unstoppable radioactive discharge into the Pacific has prompted experts to sound the alarm, as cesium, which has a much longer half-life than iodine, is expected to concentrate in the upper food chain.. According to Tepco, some 300,000 becquerels per sq. centimeter of radioactive iodine-131 was detected Saturday, while the amount of cesium-134 was 2 million times the maximum amount permitted and cesium-137 was 1.3 million times the amount allowable.. ***.

RE: CBS, a complicated ownership arrangement. KPIX may still be owned by Westinghouse, builder of nuke plants). This might explain the Fuku-denialism & denial of radiation in West Coast waters of the U.S. Controlling interest now held by one individual. Fr. Wikipedia:. In 1994, Westinghouse signed a long-term affiliation deal to affiliate all five of its Group W TV stations with CBS.[113][114] Of the other four stations, two of the stations (KPIX in San Francisco and KDKA-TV in Pittsburgh) had been decades-long affiliates of the network, while KYW-TV in Philadelphia and WBZ-TV in Boston were NBC affiliates. The network decided to sell off existing O&O WCAU, which would eventually be purchased by NBC, despite at the time being much higher rated locally than KYW-TV. While WJZ-TV and WBZ-TV switched to CBS in January 1995, the swap was delayed in Philadelphia when CBS discovered that an outright sale of channel 10 would have forced it to pay massive taxes on the proceeds from the deal. To solve ...
Description: Crystalline silicotitanate (CST) is an ion-exchange method for removing radioactive cesium from tank waste to allow the separation of the waste into high- and low-level fractions. The CST, originally developed Sandia National Laboratories personnel in association with Union Oil Products Corporation, has both a high affinity and selectivity for sorbing cesium-137 from highly alkaline or acidic solutions. For several years now, the U.S. Department of Energy has funded work to investigate applying CST to large-scale removal of cesium-137 from radioactive tank wastes. In January 1997, an expert panel sponsored by the Tanks Focus Area met to review the current state of the technology and to determine whether it was ready for routine use. The review also sought to identify any technical issues that must be resolved or additional CST development that must occur before full implementation by end-users. The CST Gate Review Group concluded that sufficient work has been done to close ...

This is an article about the facts on nuclear war and what would happen and how you would survive and what youd need to do if you did survive a nuclear attack. A very sobering look into the atomic fury and what it would take for this disaster to happen and what you would need to do in order to live through it.
110 miles away, in the region of Bryansk, nearly 2 million acres received a heavy dose of radioactive pollution, primarily Cesium-137. Hundreds of thousands of people still inhabit this largely agricultural area, and the greatest danger they face is the ingestion of radioactive particles (or radionuclides) that have accumulated in the meat, fat, and milk of local cattle, as well as the produce from local farms and gardens. In some provinces over 20% of all dairy milk is dangerously contaminated. Children receive the highest doses of cesium, as they tend to ingest more dairy products than adults and their still-growing bones absorb more pollutants from their food. ...
Haploinsufficiency of Meis1 is a potential model system for simulating RLS in mice. Here, we show that this Meis1 deficit causes a sex- and context-dependent RLS-related phenotype at middle age, impaired sensorimotor gating ability that was refractory to the D2/3R agonist pramipexole as well as increased social memory. These behavioral abnormalities occurred without differences in thermal sensitivity, plasma iron concentrations or dopaminergic neuron number in the SNpc/VTA. Thus, although Meis1 haploinsufficiency causes the RLS-related phenotype of motor restlessness in mice, the detailed nature of these effects is complex. Furthermore, it is characteristically distinct from other genetic RLS models (e.g. Btbd9 knock-out), highlighting the heterogeneous nature of the effects of these different risk genotypes in this disease.. Motor restlessness in these Meis1-haploinsufficient mice was detected previously in young adult male and female mice (Spieler et al., 2014). RLS is, however, more prevalent ...
One of the most infamous symbols of life-threatening pollution is the Chernobyl reactor, which suffered a meltdown in April 1986. To this day, the settlements closest to the reactor site remain depopulated ghost towns; however, the explosion sent a radioactive cloud over most of Europe, and many regions received a fallout level that, while not quite serious enough to require permanent evacuation, is still more than enough to blight local ecosystems and human communities with radiation poisoning. 110 miles away is the region of Bryansk, of which nearly 2 million acres received a heavy dose of fallout pollution, primarily Cesium-137. Hundreds of thousands of people still inhabit this largely agricultural area, and the greatest danger they face is the ingestion of radioactive particles (or radionuclides) that have accumulated in the meat, fat, and milk of local cattle, as well as the produce from local farms and gardens.

Why are we here, whats it all about? The Monty Python team is trying to sort out the most important question on Earth: what is the meaning of life? They do so by exploring the various stages of life, starting with birth.

In the growing and learning part of life, Catholic schoolboys attend a rather strange church service and ditto sex education lesson.

TJ Olsen last week underwent the first of three open-heart surgeries scheduled before his third birthday. The first procedure is the most risky and invasive, but the doctor who performed the surgery said early signs are positive. Olsen, in his second year with the Panthers, will be spending several nights a week at the Charlotte hospital, where TJ will remain for about 40 days. He said hes grateful for the support of the Panthers, including owner Jerry Richardson, who chartered a plane and accompanied the Olsens to Boston in May for consultations with pediatric heart specialists. TJs middle name is Jerry in honor of the Panthers owner. Meanwhile, Olsen is the Panthers leading receiver with 22 catches and ranks among the top 10 tight ends in the league in receiving with 293 yards and a touchdown. NOTES: Ron Rivera tiptoed around the issue during the bye week, but will have to decide this week who starts at middle linebacker. Pro Bowler Jon Beason, coming off Achilles surgery a year ago, ...
