High-density lipoprotein (HDL) cholesterol levels are a strong inverse predictor of
cardiovascular events. However, it is not clear whether this association is maintained
at very low levels of low-density lipoprotein (LDL) cholesterol.
A post hoc analysis of the recently completed Treating to New Targets (TNT) study
assessed the predictive value of HDL cholesterol levels in 9770 patients.
of English already, and how much basic language do they know? If your students are at a very low level, look out for the Extra support ideas in the Teachei s Book. If they are stronger, look out for the Extra challenge ideas.
In order to meet the increasing demand for valve-regulated lead–acid ŽVRLA. batteries, a new soft lead has been produced by Pasminco Metals. In this material, bismuth is increased to a level that produces a significant improvement in battery cycle life. By contrast, other common impurities, such as arsenic, cobalt, chromium, nickel, antimony and tellurium, that are known to be harmful to VRLA batteries are controlled to very low levels. A bismuth ŽBi.-bearing oxide has been manufactured ŽBarton-pot method. ...
Risk Assessment Vaccines are considered safe when the risk of use is judged to be acceptable in relation to the benefits. For vaccines given to healthy individuals for diseases that are no longer common, acceptable risks are set at very low levels—indeed, far lower than for most medical products. However, "safety" does not and cannot ever mean "zero risk." The determination of safety is thus based on a scientific assessment of the data and a considered judgment of all the issues involved, including benefits and risks.
More recently the results of the Prostate Cancer Prevention Trial (PCPT) (Thompson et al.
2003) demonstrated that there is no PSA threshold below which one can confidently
exclude a diagnosis of prostate cancer. The PCPT trial protocol required “normal” men
with very low levels of PSA to be biopsied at the end of the trial and it was observed that
39.2% of men with a PSA 2.1-3.0 ng/mL, 27.7% of men with a PSA 1.1-2.0 ng/mL, and
16.3% of men with a PSA
There are other interesting parallels: In both countries, changes in investment ratios seem not to have
been triggered by changes in household savings ratios, but have shown separate trends: In Germany,
the investment-to-GDP ratio rose from 1951 to 1954 from 20 to 25 per cent, and hovered between
23 and 25 per cent until the late 1960s. The household savings rate, on the other hand, started from a
very low level of just 4 per cent of disposable income in 1950 (which even translates into a lower share
of GDP as disposable income is only a share of GDP) a...
There is increasing evidence that health effects occur at very low levels of PM, and without an apparent
threshold. This evidence arises from studies, initially in the US, but which have more recently been
carried out in Europe and elsewhere with similar conclusions. These studies have, in general, used
different measures of particles, but the majority have used PM10 and the Group felt that this was the most
appropriate measure for a limit value for particles at the present time.
Based on past WPI inflation data, we see that every time the real rate turned positive,
the regulator reduced the SB rate
, never to take corrective action (in terms of increasing
the SB rate) even on subsequent high negative real rates. Chart 1 provides this picture in
very clear terms. From 2003 to 2009 the real rates on SB accounts remained at historically
low levels and persisted there for six years. Barring the transitory reversal in end 2009,
this high negative real rate continues to pinch the small savers till date. One can clearly see
that at least during April...
the end consumer as the most important element in the food chain, and to re-
construct the single elements of the food production and distribution process
from the consumers perspective – in other words to start a reversed food
chain thinking. This approach makes it possible to come to a kind of
hierarchical analysis of the research issues in three main categories1
Consumer confidence in food safety has recently dropped to very low levels,
as illustrated e.g.
Oracle has focused development around a single source code model since 1983.
While each database implementation includes some operating system–specific
source code at very low levels in order to better leverage specific platforms, the inter-
faces that users, developers, and administrators deal with for each version are consis-
A severe challenge to the idea that mitochondrial DNA mutations play a major role in the aging process in mammals is that clear loss-of-function mutations accumulate only to very low levels (under 1% of total) in almost any tissue, even by very old age. Their accumulation is punctate: some cells become nearly devoid of wild-type mitochondrial DNA and exhibit no activity for the partly mitochondrially encoded enzyme cytochrome c oxidase. Such cells accumulate in number with aging, suggesting that they survive indeﬁnitely, which is itself paradoxical....
It is accepted globally that a “leaner” yet ‘bigger’ dairy industry is much more productive than small farm
holdings. Contrary to this belief we suggest mechanization is not an alternative but can be a complement
to smallholding farms. Mechanization is understood as loss of jobs for farmers. This may be true for the
crop sector; however, in dairy farming this is not always the case. Given Pakistan’s spread of
smallholdings and very low level of existing mechanization; job losses are unlikely to happen.
One of the international challenges is to actually create an infrastructure in many countries that constructs
schools and equips them with trained teachers so children can experience a basic education. The UN
millennium development goals reflect this and great progress is being made on access to a universal basic
education. However it is a modest goal that, for example, doesn’t necessarily apply to teenagers.
Unlocking Forest Bonds was a workshop hosted by the WWF

Tumor suppressor protein p53 plays a central role in maintaining genomic integrity
[1–3]. In unstimulated cells p53 is maintained at very low levels but in response to
DNA damage or other stress stimuli, such as hypoxia or activation of oncogenes,
p53 becomes stabilized and accumulates in the cell [4, 5]. p53 can exert its tumor
suppressor function in different ways (Fig. 1.1).
The annual summer warming of the Arctic in 2008 was watched closely by an army of
expert observers and other interested parties around the world. Organisations such as
the US National Oceanic and Atmospheric Administration (NOAA)3 published neardaily
updates on the state of the Arctic sea ice, which every year recedes from its winter
maximum as the summer comes to the far north. The reason for this scrutiny was the
record low level of Arctic sea ice extent observed in summer 2007, when an area of ice
nearly the size of Alaska melted.
Thorough evaluation of the infertile couple before in vitro fertilization (IVF) is critical in achieving the best outcomes and avoiding complications. Most IVF centers organize the evaluation by using a checklist that the nurse coordinator and physician assure is complete before proceeding with the cycle. DAY 3 FOLLICLE-STIMULATING HORMONE A level exceeding 25 mIU/ml (about 12 mIU/ml using current assays) has been correlated with a very low chance of pregnancy (1).
In their classic account, Tim Dyson and Mick Moore linked women's autonomy to
demographic regimes in south Asia. As they describe the north Indian demographic regime, it involves
relatively high levels of fertility and infant mortality, relatively early age at marriage (which is almost
universal in north India), and relatively large gender gaps in health indicators.
Organic farming is a growing sector in Thailand, which is encouraged by the government and
many private initiatives. Therefore, production is expected to rise to meet the growing demand in
the domestic market for organic foods. The increased range of healthy foods and the establish-
ment of certificates for pesticide controlled vegetables indicate that there is a potential market.
Consumers everywhere know very little about the production process, as there is no identifica-
tion with the product and its producer.
