Month: April 2022

A few days after the presentation of Poco F4 GT , Xiaomi presented Poco M4 5G in India , an entry-level product but not poor in the specification. The Pro version , we recall, was presented in November last year.

To keep the price low, Poco has made a rather unusual choice: instead of abounding with cameras, which in this segment cannot necessarily be particularly performing, Poco has placed “just” two on the back so as to concentrate the efforts on the rest of the data sheet .

The result is a smartphone with a large and defined display , sufficiently fast memories, a connectivity compartment that, apart from NFC, lacks nothing and a large battery , with the plus of the IP52 certification which, despite not putting who knows how much shelter from unpleasant encounters with liquids, it is still a peace of mind that a large part of the competition cannot afford to offer.

It was made official in India where it will arrive on May 5 in three colors, Cool Blue, Power Black and Poco Yellow, at the (equivalent) price of 160 euros for the configuration with 4 GB of RAM and 64 GB of storage and 185 euros for the 6 + 128 GB.

A weakened immune system will not respond properly to the vaccination. This is especially true of the elderly and the chronically ill. Immunologists say that with age, the immune system “wears out” – explains prof. Piotr Trzonkowski, immunologist from the Medical University of Gdańsk.

Prof. Piotr Trzonkowski shared his thoughts during a debate organized by the Foundation for Polish Science entitled: “Why do properly vaccinated people sometimes suffer from COVID-19?”. He recalled the effect of aging – as a natural process that influences the effectiveness of medical treatments, including vaccination.

Immunologists say that as you age, your immune system “wears out”. As we age, we lose the thymus – the organ that produces T cells – responsible for cellular immunity in the body. They too help build immunity after vaccination.

He also mentioned another mechanism that regulates the response of the immune system – the so-called “The body’s pro-inflammatory readiness.”

Older people have a high level of pro-inflammatory cytokines in the body, responsible for the so-called “Cytokine storm”. If we were to compare a 20-year-old and an 80-year-old, the normal, physiological levels of pro-inflammatory cytokines in an 80-year-old are so high that they would cause sepsis in a 20-year-old. So the willingness to enter a cytokine storm and hemorrhagic pneumonia after infection is much greater. These are the reasons why elderly people react poorly to vaccinations, and when they start to get sick, they get seriously ill “- explained the immunologist. He also recalled that the main role of the vaccine is to protect against hospitalization and death. “There has been a study conducted on 100-year-olds in Italy that showed the elderly get sick, but the vaccine – in this case the flu vaccine – protects them from dying. prof. Trzonkowski explained prof. 

In his speech, the expert also discussed the cases of young people suffering from chronic diseases, whose immune system does not respond to vaccination. 

Here the conditions are dictated by the nature of the disease. In some patients who are taking immunosuppressants, the immune system will not respond because the drugs stop it working. The immunologist said.

In turn, prof. Michał Witt, geneticist and molecular biologist, director of the Institute of Human Genetics of the Polish Academy of Sciences in Poznań – points out that medicine has not found such drugs that would work 100%. Therefore, you should not expect 100%. the effectiveness of any vaccine.

Medicine has not found such drugs that would work 100 percent. We’d love to do that, but it hasn’t happened yet. We know that vaccines on the market have a limited mode of action. We know that the flu vaccine is 40-60 percent effective, the tetanus vaccine is 90 percent effective, and the pertussis vaccine is 70 percent effective. These ranges are different in each case.
prof. Witt mentioned

He also added textbook information on genetics to help understand why everyone responds differently to medications and vaccinations.

Genetics says that each of us is different and each of us has a different equipment – a different genetic profile – also in terms of genes that determine immune resistance. Therefore, we react differently. You also have to take into account the lifestyle we are at and what other diseases we are struggling with. The immune system does not work the same all the time – it has its ups and downs – depending on how and what it is attacked (e.g. with other infections). Prof. Michał Witt said.

A few days ago, we learned about the details of the $800 million package of weapons the United States wants to hand over to Ukraine. It will include a brand new Phoenix Ghost tactical drone, designed specifically for Ukraine by the United States Air Force.

The U.S. will certainly provide Ukraine with over 121 Phoenix Ghost tactical unmanned aerial systems manufactured by AEVEX Aerospace.

It was officially announced by the Pentagon, while an official of the Department of Defense revealed that the new drone “was quickly developed by the Air Force in response to Ukraine’s requests.

These words were later corrected by the Pentagon press secretary, who said the drone was built before Russia invaded Ukraine on February 24.

It is said that this drone was developed in consideration of the requirements that correspond very precisely to what the Ukrainians now need in the Donbass.

There is no question that this is an example of a kamikaze drone attack directly hitting the target.

We know that this new system will require minimal training for Ukrainian operators already familiar with Switchblade or other unmanned aerial vehicles.

Lift is a vertical mouse that is sold in both left-handed and right-handed versions. It costs 69.99 euros and is available in three colors.

The last two years have been a challenge for health, but not only because of the coronavirus epidemic. Forced to work from home, we have had to compromise on ergonomics , typing for long hours on laptops, without external monitors at the right height, on uncomfortable chairs, or with mice that don’t fit well in the hand.

Logitech’s latest mouse, announced today, tries to fix at least this last point and does it from a new angle. One of 57 degrees , to be exact. Lift is a vertical mouse that joins the company’s Ergo series of ergonomic devices and is sold in both left-handed and right-handed versions. It costs 69.99 euros and can be purchased from today in three different colors on the manufacturer’s website or at its usual distributors.

What makes it special? Instead of having the buttons at the top, the Lift buttons are on a 57 degree inclined plane with respect to the horizontal support surface. This tilt changes the position of the hand during use and completely relaxes the tension on the wrist . I have been able to test it during the last week and it is a great alternative for those who notice, at the end of the day, excessive pressure or pain in the hand with a conventional mouse.

When using it, it has a thumb rest and the rest of the hand is dropped on the side. The posture is somewhat reminiscent of the one we would use to shake someone’s hand. It is comfortable, neutral, and allows you to grip the mouse firmly so as not to lose precision. The device feels comfortable and warm to the touch and is made mostly from post-consumer recycled plastic.

Lift isn’t Logitech’s first vertical mouse. The company has also been selling the MX Vertical for months, but it is a much larger mouse that can be somewhat uncomfortable in medium or small hands. It’s also more expensive, because it offers a USB-C connection and a rechargeable battery inside, instead of using an AA battery like the Lift does.

It is also somewhat noisier. One of the great advantages of Lift is that the buttons and scroll wheel make almost no noise, although the scroll wheel’s spin isn’t as satisfying as other MX-series mice.

The wheel turning system is magnetic, like on other MX-series products, so it has great precision and speed when scrolling through a long document, but not as fast as, say, a Logitech MX Master 3 (which is by far my favorite mouse).

Setting up the Lift is easy. It connects to the computer or tablet via Bluetooth or radio frequency (it includes a receiver for the USB-A port of the computer in the latter case). It can memorize up to 3 different devices and has five buttons in addition to the scroll wheel . Two are accessible from the thumb, two (the main ones) with the index and middle fingers and a third button is just below the scroll wheel.

Although it is automatically detected as a standard mouse, the Logitech Settings application allows you to associate shortcuts and advanced functions to the different buttons.

For those who aren’t comfortable with a conventional mouse or suffer from repetitive strain injuries after years of use, Lift can be a great relief, though those with larger hands may find the MX Vertical an even more comfortable alternative. comfortable.

Disappointed by the yields and quality of Samsung’s EUV engraving, the American Qualcomm would have accelerated the launch of the “Plus” version of its high-end mobile chip Snapdragon 8 to switch to TSMC. And offer an updated version that is more energy efficient.

The “+” version of Qualcomm’s high-end mobile processor could be more than a small update this year. While Qualcomm has been offering a slightly refined version of its SoC in the middle/end of the year for a few years, the American would have advanced the launch schedule of its Snapdragon 8 Gen 1 Plus to May for quality reasons.

After years at TSMC, Qualcomm trusted Samsung last year for the 4 nm EUV engraving of its Snapdragon 8 Gen 1. However, in addition to yields that would not satisfy Qualcomm (some rumors report 35% at Samsung and 70% at TSMC), the first tests also show that the chip heats up too much, and too quickly. Not all 4nm prints are created equal, and TSMC still seems to be the king in all areas.

The Snapdragon 8 Gen 1 Plus should therefore be less subject to rapid temperature rises and offer additional battery power thanks to more measured energy consumption. Which does not fail to raise the question of its integration into the terminals. In the past, the “plus” versions have often found themselves in somewhat less luxurious terminals – Realme X3 Superzoom . But it would seem fashionable here that the current flagships – Oppo Find X5 Pro, etc. – can also benefit from updates in order to be not only better equipped, but also more powerful and more sober.

Qualcomm should take advantage of the announcement of mid-range SoCs (Snapdragon 7xx?) in May to formalize the launch of this Snapdragon 8 Gen 1 Plus. According to some sources, some (non-European?) versions of the next Galaxy Fold 4 and Flip 4 could feature this new chip.

The upcoming Realme Q5 has been certified by TENAA. Now we know almost the entire specification of the pre-release smartphone because of this. 

Realme Q5, along with the Realme Q5 Pro model, is to be unveiled on April 20. 

The Chinese certification authority TENAA has revealed that the Q5 will be equipped with a 6.59-inch LCD screen with Full HD + resolution. 

The model bearing the model no RMX3478 is also to have an octa-core processor clocked at 2.2 GHz Processor  type was not specified, but it looks like Snapdragon 695 with a 5G modem. However, it was specified that the phone will be offered with 6, 8 or 12 GB of RAM and 128 or 256 GB internal memory.

Realme Q5

Realme Q5 will also have two cameras: 16 Mpx in the front and 50 Mpx in the back. So that the rear camera does not look too low grade, there will also be two 2-megapixel eyelets for macro and background blurring. Q5 will also have – as you can see – a minijack and a side fingerprint reader, and in addition – Android 12. There will be three housing colors to choose from, and everything will be 164.3 x 75.6 x 8.5 mm and weigh 195 g.

According to a new study, adopting a healthy lifestyle can protect against dementia (a mental illness that results in memory loss).

According to researchers, men and women who adopt a healthy lifestyle not only live longer but are also protected from Alzheimer’s or dementias.

Dr Claudian Dahana, who led the study, said that eating vegetables, berries, whole grains, and minimally fried foods, exercising regularly, and keeping oneself mentally active can prevent Alzheimer’s disease or mental retardation.

He said that reading books, visiting museums and crossword puzzles or other such mental activities are very useful for staying mentally active.

Dr. Claudian Dahana Rush is an assistant professor of internal medicine at the Institute of Healthy Aging Chicago (USA).

Heartburn is a very unpleasant condition. Many people must have felt the characteristic burning behind the breastbone when bending down and after a hearty lunch. What causes heartburn and what does this symptom result from? How to deal with heartburn and what are the therapeutic options in this case?

Heartburn is an unpleasant burning sensation behind the breastbone in the esophagus. This may be accompanied by a sour taste in the mouth and the burning sensation may extend up to the throat. Heartburn is caused by abnormal reflux of acid in the stomach into the esophagus. The esophagus is not adapted to the acid content and causes irritation and in some cases even deeper damage.

Chest pain and heartburn – differentiation
Heartburn may be accompanied by chest pain which in some cases resembles the angina of a heart attack. It is worth being aware of this, as these causes of chest pain should be differentiated.

In the event of the regurgitation of gastric contents, pain is provoked by a copious meal, bending, and lying down – these activities increase the regurgitation of irritating contents into the stomach. In the case of angina symptoms, the pain worsens under the influence of stress, physical exertion, cold air, but also – a heavy meal, and disappears after the cessation of physical exertion.

However, in the case of a heart attack, the pain lasts longer (more than 20-30 minutes) and does not go away after the end of physical activity. It may be accompanied by other symptoms, such as shortness of breath, weakness, nausea, vomiting, as well as profuse sweating.

If a patient develops chest pain, it is necessary to conduct a thorough medical history and perform an ECG test, which will initially help to differentiate the causes of chest pain.

Heartburn – causes of heartburn

Heartburn is the most important symptom of gastro-oesophageal reflux disease – that is, the regurgitation of acidic gastric contents into the esophagus, which leads to unpleasant symptoms for the patient. What is the result of the appearance of this symptom? The most important causes of heartburn are:

Hiatus sliding hernia – this condition consists in the fact that part of the stomach moves from the correct anatomical position, i.e. from the abdominal cavity to the chest cavity. The hernia causes the gastroesophageal barrier to be weakened, which allows the contents of the stomach to flow back into the esophagus,
Slower gastric emptying – prolonged gastric content in the stomach and its accumulation promotes heartburn, slower gastric emptying may accompany diabetes and some neurological diseases,

Smoking – affects the symptoms in such a way that it reduces the tension of the lower esophageal sphincter (LES in short), which is a specific anti-reflux barrier, too low its tension predisposes to reflux gastric contents into the esophagus,

Alcohol – its abuse also predisposes to reflux, because, like cigarettes – it reduces LES tension,
High-fat diet – fatty foods release the hormone cholecystokinin – a substance that lowers LES tension. Symptoms of reflux are also aggravated by acidic and spicy foods,
obesity, overweight – excess body weight increases the pressure in the stomach and changes the position of the LES, which predisposes to reflux,

Pregnancy – this condition also contributes to acid reflux. This is because the pressure in the abdomen increases during pregnancy, as well as the concentration of estrogen (sex hormones), which reduces the tone of the LES, so heartburn often affects women during pregnancy.
taking medications that lower the LES tension – these include, among others: calcium channel blockers (commonly used in the treatment of hypertension), nitrates, oral contraceptives, or β2-agonists (used in the treatment of asthma).

Heartburn – pharmacological treatment of gastro-esophageal reflux disease
Medicines that reduce the secretion of hydrochloric acid are the mainstay of pharmacological treatment of heartburn . The first-line drugs are proton pump inhibitors, which we refer to as PPIs for short. The following should be mentioned here:

1. omeprazole _
2. rabeprazole,
3. lansoprazole,
4. esomeprazole,
5. pantoprazole,
6. dexlansoprazole.

These drugs are used in the morning, on an empty stomach, at the beginning of the therapy with one capsule / tablet – taken once a day. Sometimes drugs that block histamine receptors are also used – more precisely, H2 blockers, which include ranitidine and famotidine. These drugs reduce gastric secretion, but by a different mechanism than proton pump inhibitors (these drugs inhibit histamine-dependent secretion of gastric acid).

What to look for when purchasing.
If you are buying a box of dates, preservatives should be listed on the label. If you like it, choose soft but dry, undamaged fruit. It should have a yellowish-brown color, natural radiance, and a pleasant odor. Dried, formally cooked dried dates are unfit for human consumption. Bacteria easily settle on the date palm, so it can not stay in the air for long.

What does a date contain?

Rich in iron, magnesium, phosphorus, mineral salts, B vitamins, carotene and even essential amino acids. It also contains a small amount of fluoride, which protects teeth from damage, and selenium, which strengthens the immune system and reduces the risk of developing cardiovascular disease.

Scientists believe that 10 pieces of dried dates a day completely meet the body’s need for magnesium, copper, and sulfur, half – iron and 25% – calcium. Dates strengthen the body, increase energy, and promote growth and development.
