The World Health Organization says it is tracking a few dozen cases of two new sub-variants of the highly transmissible Omicron strain of the coronavirus to assess whether they are more infectious or dangerous. It has added BA.4 and BA.5, sister variants of the original BA.1 Omicron variant, to its list for monitoring. It is already tracking BA.1 and BA.2 - now globally dominant - as well as BA.1.1 and BA.3. The WHO said on Monday (April 11) it had begun tracking them because of their "additional mutations that need to be further studied to understand their impact on immune escape potential". Viruses mutate all the time but only some mutations affect their ability to spread or evade prior immunity from vaccination or infection, or the severity of disease they cause. For instance, BA.2 now represents nearly 94% of all sequenced cases and is more transmissible than its siblings, but the evidence so far suggests it is no more likely to cause severe disease.

AstraZeneca on Wednesday (April 5) said a combination of its cancer drugs Imfinzi and Lynparza met the main goal in a late-stage trial in patients with advanced ovarian cancer. The drugmaker said treatment with a combination of those drugs, along with chemotherapy and bevacizumab - the existing standard of care - improved progression-free survival in newly diagnosed patients with advanced ovarian cancer without certain mutations. Lynparza is jointly developed with U.S.-based Merck & Co as a treatment for breast cancer in early stage with certain mutations. Imfinzi alone, along with chemotherapy and bevacizumab, did not reach statistical significance in its interim analysis, the drugmaker added. Philipp Harter, director, Department of Gynaecology and Gynaecologic Oncology, Evangelische Kliniken Essen-Mitte, Germany and principal investigator for the trial, said: "DUO-O showcases the power of academia and industry collaboration in advancing new treatment combinations for patients with ovarian cancer. I'm grateful for the academic cooperative study groups and patients around the world that made this trial possible and look forward to sharing the results with the clinical community." Susan Galbraith, executive vice president, Oncology R&D, AstraZeneca, said: "While there has been significant progress for patients with advanced ovarian cancer, an unmet need still remains. These data from the DUO-O trial provide encouraging evidence for this this Lynparza and Imfinzi combination in patients without tumour BRCA mutations and reinforce our continued commitment to finding new treatment approaches for these patients. It will be important to understand the key secondary endpoints as well as data for relevant subgroups."

BioNTech and Pfizer are to start tests on humans of next-generation vaccines that protect against a wide variety of coronaviruses in the second half of the year. Their experimental work on shots that go beyond the current approach include T-cell-enhancing shots, designed to primarily protect against severe disease if the virus becomes more dangerous, and pan-coronavirus shots that protect against the broader family of viruses and its mutations. In presentation slides posted on BioNTech's website for its investor day, the German biotech firm said its aim was to "provide durable variant protection". The two companies are currently discussing with regulators enhanced versions of their established shot to better protect against the Omicron variant and its sublineages. The virus' persistent mutation into new variants that more easily evade vaccine protection, as well as waning human immune memory, have added urgency to the search by companies, governments and health bodies for more reliable tools of protection. As part of a push to further boost its infectious disease business, BioNTech said it was independently working on precision antibiotics that kill superbugs that have grown resistant to currently available anti-infectives.

Scientists have found a mutation in stem cell genes, which they claim could be linked to development of leukaemia and other cancers. An international team, led by Peter Papathanasiou of The Australian National University, has completed a three-year screening project to find the genes that control development and turnover of stem cells. Stem cells can grow into any other kind of cell in the body, making them a hot area of research to find new treatments for diseases and injuries

'Tepotinib' has been recommended by the National Institute for Health and Care Excellence (NICE) to patients with a specific gene mutation of advanced non-small-cell lung cancer (NSCLC). The new potentially life-extending drug is available from Thursday (14 April). It has been recommended for routine use across the NHS in England through Project Orbis, a programme to review and approve promising cancer drugs helping patients access treatments faster. NICE has published its final appraisal document recommending tepotinib (also known as Tepmetko and produced by company Merck Serono Ltd) as an option for treating advanced NSCLC with METex14 skipping gene alterations in adults. People with METex14 skipping alterations of NSCLC make up between 1-2% of all adults with lung cancer in England. Tepotinib, which requires people to take two tablets once daily, provides a new targeted treatment for adults with METex14 skipping gene alterations. Just over 700 people in England would be eligible to receive tepotinib as either a first or second-line treatment.

NHS England is set to roll out a new test this week that will help doctors to spot a rare form of eye cancer in babies in the womb. The NHS test developed at Birmingham Women's and Children's NHS Foundation Trust, identifies the risk of developing retinoblastoma in babies that can be monitored and treated sooner - increasing the chance of saving their eyesight and potentially their lives. The new non-invasive test can detect changes in the genes in DNA and is likely to identify around 50 infants with retinoblastoma each year, in the latest example of the NHS harnessing the power of genomics to diagnose and treat patients faster and more effectively. Non-Invasive Prenatal Diagnosis (NIPD) also means parents can be informed early in pregnancy if their child is at risk. "The blood sample test is taken from the mother before birth and tested and analysed for mutations, which can determine with almost 100 per cent accuracy if the baby will develop retinoblastoma," the NHS said.

Capitalising on strong demand for its obesity therapies, Novo Nordisk's growing appetite for deals has fuelled a bet on a U.S. gene-editing company called Life Edit Therapeutics. The Danish drugmaker's collaboration with Durham, North Carolina-based Life Edit Therapeutics - owned by ElevateBio, a cell and gene therapy company in Waltham - is focused on up to seven programs for rare genetic disorders as well as cardiometabolic diseases. At the heart of the tie-up is Life Edit's technology, called base editing, which is designed to make precise changes to the human genome by tweaking one base - or letter - into a different one without affecting other letters. Single-letter mistakes, called point mutations, can give rise to genetic diseases.

Pharmaceutical giant AstraZeneca will acquire biotechnology company Neogene Therapeutics for up to $320 million, the London-listed drugmaker said on Tuesday (November 29) as it seeks to build its pipeline of cell-based cancer treatments. Though AstraZeneca's oncology portfolio accounted for more than a third of the company's revenue last year, it does not have an approved cell-based cancer therapy and is behind rivals such as Novartis and Gilead. "Neogene's leading (T-cell receptor) discovery capabilities and extensive manufacturing experience complement the cell therapy capability we have built over the last three years," said Susan Galbraith, AstraZeneca's executive vice president of oncology research. Cell-based treatments are a relatively new approach to treating cancer, most of which involve drawing the body's own immune cells and processing them in the lab to target and kill cancer cells. Neogene's approach goes one step further in that its experimental T-cell receptor therapies seek to target DNA mutations specific to tumours, not only certain proteins on the surface of cancer cells.

Johnson & Johnson said on Wednesday (January 18) that it was pulling the plug on a late-stage global trial of an HIV vaccine after the shot was found ineffective at preventing infections. The failure of the trial marks yet another setback in the search for a vaccine against a virus known to mutate rapidly and find unique ways to evade the immune system, and comes more than a year after another of J&J's HIV vaccine failed a study. "It's not the outcome we had hoped for, unfortunately," said a spokesperson for the National Institute of Allergy and Infectious Diseases, a J&J partner in the trial. "The development of a safe and effective HIV vaccine has been a considerable scientific challenge, but we will learn from this study and continue forward." The trial involved administering two different types of a shot, which uses a cold-causing virus to deliver the genetic code of HIV, spread over four vaccination visits in a year. J&J used similar technology for its COVID-19 vaccine. The study, which began in 2019, was conducted at over 50 sites and included about 3,900 gay men and transgender people - groups that are considered vulnerable to the infection.

AstraZeneca said on Monday (June 27) two of its existing therapies were recommended for treating patients with some forms of high-risk breast cancers in the European Union, in a boost to the company's oncology portfolio. Lynparza, a cancer drug developed jointly with U.S.-based Merck, was backed for standalone use or in combination with endocrine therapy in adults with a form of genetically mutated early-stage breast cancer. The drug, which has received a similar recommendation in the United States in March, is a key asset for AstraZeneca. It was recommended in patients with low-to-normal levels of a protein known as HER2 that is the target of several new therapies. Enhertu - developed jointly with Japan's Daiichi Sankyo (4568.T) - was the other drug that was endorsed by the European Medicines Agency for treating an aggressive form of breast cancer characterised by a high rate of HER2.

The drug, alpelisib, which is the 100th cancer drug that has being fast-tracked to patients under the NHS Cancer Drugs Fund (CDF) will be used in combination with the hormone therapy, fulvestrant, to target the gene that causes fast-growing tumours. Up to 3,000 people a year with a certain type of secondary breast cancer will benefit from the treatment. The approach has contributed to people in England having access to nearly one third more cancer drugs compared to the European average. The drug which is manufactured by pharmaceutical company Novartis, is part of a growing number of precision treatments that target a tumour based on mutations in its DNA and that the NHS is rolling out. John Stewart, NHS National Director for Specialised Commissioning said, "In just over five years, more than 80,000 people have benefitted from earlier access to a range of cancer drugs, with people in England having access to nearly one third more cancer drugs compared to the European average, and this latest innovative new treatment will help up to 3,000 more to live a better quality of life.

French drugmaker Sanofi said on Monday (June 13) an upgraded version of the Covid-19 vaccine candidate it is developing with GSK showed potential in two trials to protect against the virus's main variants of concern, including the Omicron BA.1 and BA.2 strains, when used as a booster shot. While the two companies' first experimental Covid shot is undergoing review by the European Medicines Agency, Sanofi and GSK have continued work on a vaccine that is moulded on the now-supplanted Beta variant, hoping still that it will confer broad protection against future viral mutations. Sanofi said this new vaccine candidate was shown to significantly boost antibody levels against a number of variants of concern, when given to trial participants who had an initial course of mRNA vaccines, a type made by BioNTech-Pfizer and Moderna. In a separate trial conducted by a French hospitals network, Sanofi's Beta-adapted booster shot triggered a higher immune response than Sanofi's first-generation shot or Pfizer-BioNTech's established vaccine in previously vaccinated volunteers.

An oral drug combination by Novartis showed promise in treating a subgroup of patients suffering from a common childhood brain cancer in a trial. In the mid-stage trial, 47 per cent of the patients that were given the two drugs Tafinlar and Mekinist saw their tumours shrink, far above a rate of 11 per cent in a comparative group of participants on standard chemotherapy, the drugmaker said on Monday, June 6. The participants, aged one to 17 years, were suffering from low-grade gliomas (LGG), the most common childhood brain cancer. The trial only included those who were found to have a mutation known as BRAF V600, a genetic contributor in about 15 per cent to 20 per cent of paediatric LGG cases. Among further results of the trial with 110 participants, the median time without disease progression was 20.1 months for those given the Novartis drug combo, compared to 7.4 months on chemotherapy. The new oral treatment candidate also caused less severe side effects than burdensome chemotherapy.

Benefits of Echinacea for Health and Wellness The Echinacea plant is still in benefit today as a dietary supplement. It has nine species, but only two of them, Echinacea purpurea and Echinacea angustifolia are generally used in supplements. Other supplements are in pill form, teas, juices, and creams. It possesses many compounds that may benefit your health. 1/10_ It treat infections and wounds Echinacea has been used for centuries to treat infections and wounds. In fact, the Native Americans used echinacea to treat their cuts, burns, bruises, and insect bites. They'd apply the fresh plant directly onto their skin to heal those wounds faster than they would have otherwise. It has also been shown in multiple studies to be effective in treating colds and other infections. This benefit is believed to be due to its immune-boosting properties that help strengthen your body's defenses against bacteria. ECZEMA People with eczema suffer from an inflammation of the skin; a cream including echinacea extract may benefit. Early research suggests that daily topical application of echinacea cream helped alleviate eczema-related irritation. It also helped create the protective outer layer of skin. Be aware of probable allergic reactions, as people with eczema generally have allergies and asthma. 2/10_Antioxidant powerhouse Antioxidants are substances that protect you from disease by neutralizing or eliminating the damaging effects of free radicals. Free radicals are atoms, molecules, or ions in your body that have an unpaired electron and can cause oxidative stress in your cells. Echinacea is a powerful antioxidant that helps fight the free radicals that cause damage to cells and tissues. Free radicals may contribute to cancer development, cardiovascular disease, arthritis, diabetes mellitus, Alzheimer's disease, and many other chronic diseases. Echinacea has been shown in studies to positively impact the immune system by boosting its response against infection-causing

The European Union's health regulator on Friday said it had recommended granting a conditional marketing authorisation for a gene therapy by Australian drugmaker CSL Ltd and partner uniQure N.V. , to treat haemophilia B, a rare bleeding disorder which is caused by genetic anomalies. About one in 40,000 people are affected by the inherited disorder, caused by a gene mutation that hampers the body's ability to make clotting protein factor IX. If approved, the treatment, branded Hemgenix, will be the first gene therapy in the European Union for the condition that is usually treated by regular injections of factor IX, the European Medicines Agency said. CSL had acquired exclusive global rights to Hemgenix in May last year from uniQure N.V.

Sun Protection Tips : The sun is a glorious macrocosm in our cosmos as it allows our planet to concur period. It does hold risks though, and too more sun danger can track to the utilization of peel soul. This is because the ultraviolet irradiation (UVR) that travels from the sun and is speak in sun rays is attentive into our skins. A basic amount of UVR is necessary for our bodies to expose vitamin D, but too much can wind to mutations in our cells, starring to sign manufacture.
