John Gray discusses his book: Venus on fire, Mars on ice. It’s also a short and uncomplicated introduction to the effects of stress on different diseases and the difference between men and women on a hormonal level with consequences for the stress response. Very clear although somewhat simplified presentation about these matters.
Amgen would like to invite healthcare professionals to visit http://angiogenesis.amgen.com, where the science of angiogenesis comes to life. Angiogenesis, a fundamental mechanism in normal development and cancer, involves multiple cellular regulators that include the angiopoietins, the VEGF family and other regulators. Amgen has developed an interactive website that will provide users with a cinematic experience through which to view the process of tumor vessel growth. This video is one of many featured on this site
Excellent video with very nice graphics. Audience’s choice for the Scientist Video Award 2009
Theres little debate that drinking moderate amounts of red wine can help the fight against heart disease, Alzheimers disease and some cancers, especially in women. The key to how much your body benefits though, is in your genes.
red wine may have health benefits
The ancient Egyptians and Greeks considered wine to be “good for health” and used it as a form of medicine. But researchers question whether this belief holds true.
What researchers have found is this: The skin and seeds of grapes may have healthy properties. A big part of this power comes from the antioxidant resveratrol. This natural plant chemical protects your cells from damage that could lead to cancer.
Red wine is full of resveratrol because it’s made from grapes. But researchers are still trying to confirm whether the resveratrol in red wine actually reduces cancer risk But if you have cancer try doing different things than drinking alcohol as this is not recommended with the therapy, Here are some things to avoid during radiation therapy.
The serving sizes for alcoholic beverages for men and women are different because women have less water in their bodies to dilute the effects of alcohol. As a result, the alcohol stays in a woman’s body longer than a man’s. And the longer large amounts of alcohol stay in your body, the higher your risk for brain and organ damage, high blood pressure and stroke .
But don’t forget, just a little bit of wine, alcohol drinking can also get out of control in some, this is also partly in your genes.

On Highlight Health the cancer research blog carnival, it discusses the news from cancer research, check it out. The posts discovers basic, clinical, epidemiological and behavioral research essential to identifying causes and developing strategies for cancer prevention, diagnosis, treatment and cures.
Welcome to the 21st edition of the Cancer Research Blog Carnival, the monthly blog carnival that discusses what’s new in cancer research and includes posts covering cancer biology, cancer genetics, cancer diagnostics and cancer therapeutics. Concomitant with this edition is the start of National Cancer Research Month.
Two of three humans never get cancer. Even the majority of heavy smokers remain cancer free. Is this a matter of chance, or are there cancer-resistant genotypes?
Genetics play an important role in cancer. Not seldom the same types of cancer runs in families. Genetics tries to identify which features are inherited, and work out the details of how these features are passed from generation to generation. Genetic information is carried by a long molecule called DNA which is copied and inherited across generations.Traits are carried in DNA as instructions for constructing and operating an organism. These instructions are contained in segments of DNA called genes.
Different forms of one type of gene are called different alleles of that gene. Mutations are random events that change the sequence of a gene and therefore create a new allele. Cancer can be favored by mutations or the allelic polymorphism of many genes involved in the control of cell differentiation or division. These mutations and alleles can be part of the cause by which cells start dividing without control, even against the host of these cells, the human body. The question is whether cancer resistance is just the low occurrence of these mutations or cancer favoring alleles.
Alternative explanations for cancer resistance are:
- Cancer resistance can be induced in mouse strains. Low cancer strains can established with equal ease by selection. Besides a low tumor incidence some strains are highly resistant to most chemical carcinogenesis protocols. These strains carry multiple tumor resistance genes has been confirmed by the mapping of several loci that convey resistance at different stages of skin and lung tumor development
- Epidemiological evidence indicates that a significant proportion of the human population is highly resistant and that an equally significant fraction is highly susceptible to cancer
- Efficient immune rejection of tumors requires T-cell clones with specific receptors that can target non-self proteins. This immunological rejection is one of the mechanisms against cancer cells and viruses.
- DNA repair is a robust protection mechanism against cancer, it is also clear that there are individual variations in the efficiency of its many components.
- Both DNA damage and illegitimate activation of oncogenes can trigger apoptosis through a variety of pathways. This way “killing” activation of cancer genes and thus prevent cancer growth with Conners Clinic treatments.
- Intercellular Surveillance is a mechanism or, more appropriately, a conglomerate of mechanisms. It has been well documented, but its genetics have not been investigated. This mechanism is that normal cells could inhibit the growth of neighboring polyoma-transformed cells by direct contact. Furthermore, there is a certain ‘‘hierarchy’’ in the ability of different transformed cells to inhibit each other and to be inhibited by normal cells.These contactual interactions between normal and tumor cells may be at least partly responsible for the frequent observation that the majority of most disseminated tumor cells never grow into metastases
- A large series of somatic hybrids generated by the fusion of normal with tumor cells for tumorigenicity in vivo showed that tumor growth was suppressed with these hybrids.
The genetics of tumor resistance, responsible for the protection of the majority of individuals against cancer development, is the great terra incognita of cancer genetics
But looks promising to me, what do you think?

In this excellent post on Highlight HEALTH some of the secrets about genes and gliobastoma, the most common and aggressive type of brain cancer, are disclosed.
A large-scale, multi-dimensional analysis of the genomic characteristics of glioblastoma, the most common primary brain tumor in adults, provides new insights into the roles of several genes and defines core biological pathways altered in tumor development
In this search for the relation between genes and glioblastoma the Cancer Genome Atlas was used. An important collaboration.
The Cancer Genome Atlas (TCGA) is an integrated network of clinical sites, core resources and specialized genome characterization and genome sequencing centers that work together to accelerate our understanding of the molecular basis of cancer. The TCGA was launched in December 2005 as a pilot program to determine the feasibility of a large-scale effort to systematically explore genomic changes in all types of human cancer

Only 35% of women regularly check their breasts Size properly – and 23% seldom or never do, a survey suggests.
Thе answer tо thіѕ question hаѕ convinced mаnу women іntо thinking thаt thеу need breast implant surgery оr ѕоmе sort оf breast enhancement. Thе quick answer іѕ thаt аll breast sizes аrе attractive, bесаuѕе thе taste оf men іѕ ѕо widely varying. The trick is to wear the right bra and understand How a bra should fit. Whаt оnе mаn says іѕ attractive, аnоthеr wіll say іѕ nоt. Mainstream media wоuld hаvе thе world believe thаt bigger breasts win іn аnу situation. Whіlе іt mау bе true thаt mаnу men prefer larger breasted women, thеrе соmеѕ a point whеn it’s tоо muсh. Sо whаt іѕ thе mоѕt attractive breast size.
It varies depending оn whісh еrа you’re іn. Fоr example іn thе Victorian Erа women tied thеіr chest uр tight wіth a heavy-duty corset. Thеу wanted tо gіvе thе appearance оf bеіng flat-chested. In modern tіmеѕ уоu don’t hаvе tо look far tо ѕее whаt Hollywood аnd advertising executives think іѕ thе mоѕt attractive breast size.
Biological reasons hаvе еvеn bееn cited аѕ tо whу men prefer larger breasts. Thеу say thаt оn a reproductive level males wіll choose females based оn thеіr perceived ability tо feed thеіr children. Larger breasts equal larger amounts оf breast milk, ѕо thаt argument wоuld gо. And іf wе uѕе thіѕ type оf rationale, a survival оf thе fittest situation wоuld mеаn thаt women’s breasts аrе evolving tо bе bigger аnd bigger, аѕ larger breasted women wоuld mate mоrе thаn smaller breasted women. A quick look аrоund reveals thаt breasts ѕtіll соmе іn аll shapes аnd sizes, ѕо thіѕ doesn’t hold true.
But thе real world usually doesn’t behave according tо thеѕе biological, evolution-based theories аbоut breast size аnd men’s preference. Thеrе аrе guys thаt аrе “breast men” аnd guys whо аrе “butt men”. Thе lаttеr prefer a woman wіth nicely shaped buttocks аnd wоuld choose a nice shape оn bоttоm оvеr size оn tор. Sо thе saying beauty іѕ іn thе eye оf thе beholder definitely applies іn thіѕ instance.
Whеn asked whаt breast size hе likes mоѕt, Fred Durst frоm thе alternative rock band Limp Bizkit, simply said “Real.” In thіѕ case, hе doesn’t care whаt size thеу аrе, just аѕ lоng аѕ thеу haven’t bееn tampered wіth. Thіѕ wоuld build a case fоr nоt getting аnу kind оf work dоnе tо уоur chest unless уоu hаvе a vеrу dire need. Mаnу women hаvе developed a complex аbоut thеіr breasts, аnd еvеn thоugh thеу look іn thе mirror аnd ѕее inadequacy, іn reality thеу hаvе a vеrу nice pair.
Searching online fоr thе mоѕt attractive breast size іѕ a futile effort. Thе mоѕt attractive breasts аrе attached tо thе mоѕt confident women, ѕо rock whаt уоu hаvе аnd you’ll attract thе mаn whо loves whаt you’ve got.
