London, May 28: Scientists have developed a quick and robust blood test that can detect liver damage before the symptoms appear. The test developed by researchers from the University College London in the UK could address a huge need for early detection of liver disease. It distinguishes between samples taken from healthy individuals and those with varying degrees of liver damage, researchers said. The study, published in the journal Advanced Materials, describes the new method of detecting liver fibrosis, the first stage of liver scarring that leads to fatal liver disease if left unchecked, from a blood sample in 30-45 minutes.

“We hope that our new test could be used on a routine basis in GP surgeries and hospital clinics to screen people who face an elevated risk of liver disease, but don’t yet show signs of liver damage to identify those with serious fibrosis, so that they can access treatment before it’s too late,” said William Rosenberg, a professor at UCL. “This may open the door to a cost-effective regular screening programme thanks to its simplicity, low cost and robustness,” he said.

Researchers at the University of Massachusetts in the US designed a sensor that uses large molecules called polymers, coated with fluorescent dyes that bind to blood proteins based on their chemical properties. The fluorescent dyes change in brightness and colour, yielding a different pattern of fluorescence depending on the protein composition of the blood sample.

The team at UCL tested the sensor by comparing results from small blood samples (equivalent to finger-prick checks) from 65 people, in three balanced groups of healthy patients and those with early-stage and late-stage fibrosis. They found that the sensor could identify different patterns of protein levels in the blood serum of people in the three groups.

“By comparing the different samples, the sensor array identified a ‘fingerprint’ of liver damage,” said William Peveler, who completed the research at UCL. “This method is known as a chemical nose, as it can recognise the difference between healthy and unhealthy blood samples without relying on known disease markers,” said Peveler.

Drinking coffee may help reduce the risk of certain digestive disorders, including gallstone disease and pancreatitis, a new study has suggested.

The study from the Institute for Scientific Information on Coffee (ISIC) also highlighted other beneficial effects that coffee consumption may have on the process of digestion, including supporting gut microflora and promoting gut motility.

"Data indicates benefits against common digestive complaints such as constipation, as well as a potential reduction in the risk of more serious conditions like chronic liver diseases," said study author Carlo La Vecchia from the University of Milan in Italy.

Gallstone disease is a common digestive disorder, caused by the accumulation of gallstones in the gallbladder or bile duct, which affects approximately 10-15 per cent of the adult population.

While the mechanism by which coffee may protect against gallstone disease is not yet known, it has been observed that the risk for the condition declines with increasing daily consumption of coffee, the researchers said.

Caffeine is thought to play a role in these associations, as the same effect is not observed with decaffeinated coffee.

A common question among consumers and focus area for research is whether coffee is associated with heartburn or gastro-oesophageal reflux disease (GORD).

While a small number of studies have suggested an association between coffee drinking and GORD, the majority of studies reviewed suggest that coffee is not a major trigger of these conditions.

The report also reviewed a growing area of health and nutrition research, namely: the effect of coffee on the gut microflora (microorganism populations).

Recent studies suggest that populations of the beneficial gut bacteria Bifidobacterium spp, increase after drinking coffee.

The findings showed the dietary fibre and polyphenols found in coffee, support the healthy growth of microflora populations.

Additional research findings highlighted that coffee consumption is thought to stimulate digestion by encouraging the release of gastric acid, bile and pancreatic secretions.

Coffee is one of the most widely researched components of the diet, and its effect on digestion remains a growing area of research, the researchers noted.

The American pharmaceutical giant Pfizer Inc. and the European biotechnology company BioNTech SE have conducted an experimental trial of a COVID-19 vaccine candidate and found it to be safe, well-tolerated, and capable of generating antibodies in the patients.

The study, which is yet to be peer-reviewed, describes the preliminary clinical data for the candidate vaccine -- nucleoside-modified messenger RNA (modRNA), BNT162b1.

It said the amount of antibodies produced in participants after they received two shots of the vaccine candidate was greater than that reported in patients receiving convalescent plasma from recovered COVID-19 patients.

"I was glad to see Pfizer put up their phase 1 trial data today. Virus neutralizing antibody titers achieved after two doses are greater than convalescent antibody titers," tweeted Peter Hotez, a vaccine scientist from Baylor College of Medicine in the US, who was unrelated to the study.

Researchers, including those from New York University in the US, who were involved in the study, said the candidate vaccine enables human cells to produce an optimised version of the receptor binding domain (RBD) antigen -- a part of the spike (S) protein of SARS-CoV-2 which it uses to gain entry into human cells.

"Robust immunogenicity was observed after vaccination with BNT162b1," the scientists noted in the study.

They said the program is evaluating at least four experimental vaccines, each of which represents a unique combination of mRNA format and target component of the novel coronavirus, SARS-CoV-2.

Based on the study's findings, they said BNT162b1 could be administered in a quantity that was well tolerated, potentially generating a dose dependent production of immune system molecules in the patients.

The research noted that patients treated with the vaccine candidate produced nearly 1.8 to 2.8 fold greater levels of RBD-binding antibodies that could neutralise SARS-CoV-2.

"We are encouraged by the clinical data of BNT162b1, one of four mRNA constructs we are evaluating clinically, and for which we have positive, preliminary, topline findings," said Kathrin U. Jansen, study co-author and Senior Vice President and Head of Vaccine Research & Development, Pfizer.

"We look forward to publishing our clinical data in a peer-reviewed journal as quickly as possible," Jansen said.

According to Ugur Sahin, CEO and Co-founder of BioNTech, and another co-author of the study, the preliminary data are encouraging as they provide an initial signal that BNT162b1 is able to produce neutralising antibody responses in humans.

He said the immune response observed in the patients treated with the experimental vaccine are at, or above, the levels observed from convalescent sera, adding that it does so at "relatively low dose levels."

"We look forward to providing further data updates on BNT162b1," Sahin said.

According to a statement from Pfizer, the initial part of the study included 45 healthy adults 18 to 55 years of age.

It said the priliminary data for BNT162b1 was evaluated in 24 subjects who received two injections of 10 microgrammes ( g) and 30 g -- 12 subjects who received a single injection of 100 g, and 9 subjects who received two doses of a dummy vaccine.

The study noted that participants received two doses, 21 days apart, of placebo, 10 g or 30 g of BNT162b1, or received a single dose of 100 g of the vaccine candidate.

According to the scientists, the highest neutralising concentrations of antibodies were observed seven days after the second dose of 10 g, or 30 g on day 28 after vaccination.

They said the neutralising concentrations were 1.8- and 2.8-times that observed in a panel of 38 blood samples from people who had contracted the virus.

In all 24 subjects who received two vaccinations at 10 g and 30 g dose levels, elevation of RBD-binding antibody concentrations was observed after the second injection, the study noted.

It said these concentrations are 8- and 46.3-times the concentration seen in a panel of 38 blood samples from those infected with the novel coronavirus.

At the 10 g or 30 g dose levels, the scientists said adverse reactions, including low grade fever, were more common after the second dose than the first dose.

According to Pfizer, local reactions and systemic events after injection with 10 g and 30 g of BNT162b1 were "dose-dependent, generally mild to moderate, and transient."

It said the most commonly reported local reaction was injection site pain, which was mild to moderate, except in one of 12 subjects who received a 100 g dose, which was severe.

The study noted that there was no serious adverse events reported by the patients.

Citing the limitations of the research, the scientists said the immunity generated in the participants in the form of the T cells and B cells of their immune system, and the level of immunity needed to protect one from COVID-19 are unknown.

With these preliminary data, along with additional data being generated, Pfizer noted in the statement that the two companies will determine a dose level, and select among multiple vaccine candidates to seek to progress to a large, global safety and efficacy trial, which may involve up to 30,000 healthy participants if regulatory approval to proceed is received.

Remember! Your workplace should be a sacred space where you are able to find a sense of comfort in your work environment. It should help you feel positive, healthier and happier, more like a protective zone.

Fabricating a Positive Workstation

There should be a separate workstation so that one can concentrate while working from home. It would be great if the work desk is stationed somewhere near a window or a balcony door so that one can welcome sunlight, fresh air and a view of plants & birds during the day. Try to have an ergonomic setting of your table and chair so that you keep your posture right while working the whole day. Keeping one or two indoor plants near your work desk will help to make it interesting.

Keep your laptop charger wires and other stuff neatly on your desk to avoid overwhelming yourself. Motivation quotes around you will help to make you overall positive. Keep your notes diary and pen handy at your desk. It will always helps to keep some colorful artifacts around you to make the atmosphere a little cheerful.

Declutter Your Workstation

Avoid the pilling up files and unnecessary stationery at your workstation. Clutter is responsible for the confusion and problems all around and it leads to distraction; thus, a clean desk reflects power which enhances positivity and creates a tranquil workspace that will help your mind focus on productivity. It is important to declutter your work desk once in a few days because physical clutter translates to mental clutter.

Gratitude Notes in workstation and how to manifest

It is a great morning practice to write at least five things you are grateful for. It helps to shift the focus from negative to positive, from scarcity to abundance. One can write gratitude statements on Post it notes and put them at the work daily. This will raise the vibrations and help you stay grounded and positive. You can also compile affirmations and prayers that you resonate. Whenever you take work breaks, it is a good idea to read these.

Crystals to imbibe positivity at workstation

Selenite is a great crystal to spread light and positivity around. Black tourmaline absorbs negativity and is great to shield you from it during lockdown. Shungite is a great crystal to reduce the effects of electromagnetic radiations around you. You can place it near your wifi router, laptop and other devices to reduce the EMF pollution effects on you and your family. Clear quartz is great for energizing you after a tiring meeting. Just hold it in your left hand with eyes closed for five minutes and visualise beautiful energy entering your body and soul.

You can combine this exercise by holding black tourmaline in your right hand and visualize all the tiredness and unwanted energy draining into the black tourmaline. Tiger eye is very effective in eliminating the scattered brain and it allows us to make confident decisions. Green Aventurine neutralizes stress and anxiety from work, allowing us to keep calm.

Lepidolite is known as the Peace Stone, making it one of the best crystals for peace. It improves our overall mood, calms us, soothes us, and reduces our anxiety with a peaceful sense of happiness.

Sodalite is a great crystal for peace because it turns fear and stress into peaceful feelings. It also helps in better communication and can help while making crucial presentations & meetings.

Fluorite is great for healing and rejuvenating the mind and body. You can close your eyes and sit quietly with Fluorite while imagining your body being filled with an incredible energy that puts you at ease with yourself and the world.

Pyrite, also known as abundance stone, is great to put over your business card to manifest abundance at work.

Don't forget to clean your crystals regularly to harness their maximum energy.

Meditate, Do Pranayam and Stay Hydrated!

It is important to take short breaks to maintain productivity at work. Being summer, it is a good idea to get up for a water break once in 30 minutes at least. Even if you keep a water bottle alongside you, walking to the kitchen for water will help your physical body get some much needed movement.

Few iterations of square breathing once in two hours is a great way to boost your mind and body. Square breathing is basically the sequence of inhalation - holding breath - exhalation - holding breath - all for equal time spans. So you can count mentally 1 to 4 in inhalations, then again counting 1 to 4 as you hold your breath, and so on and so forth.

You can also chant any mantra while taking a work break for 1 or 2 minutes. While attending online meetings, where there is nothing much your hands are doing, you can utilize that time to do Yoga Hast/Hand Mudras and harness their energies. Pran Mudra is one of the best options to practice while attending meetings or reading articles, where your hands are free essentially.

You can Also -

Dress up like you would do while going to office so as to feel good in general

Go out on your terrace/balcony once or twice a day to get some fresh air, sunlight and hear birds chirping

Say yes to distractions rather than getting irritated from them, because you cannot avoid them while working from home, like the kids, TV sounds, kitchen sounds etc.
