Research States that C.1.2 variation: New Covid strain has most mutation rate yet

Published

on

A new report recognized a new Covid strain that can possibly turn into a variation of concern — like the alpha, beta and delta variations, which have pummeled nations all throughout the planet with substantial influxes of new COVID-19 diseases and passings.

The most up to date strain, named C.1.2, comes from a similar genealogy as the beta variation from South Africa, as per the investigation, and was first recognized in May 2021.

Analysts noticed that it was “sudden” to see a transformation so before long the disclosure of the first strain, C.1, back in January, however examining and genome sequencing tracked down that the C.1.2 variation “had changed generously.”

C.1.2 has a very high pace of change, as indicated by the examination. The new variation showed between 44-59 changes from the first COVID-19 strain, which is more than some other variation of concern or variation of interest.

The C.1.2 variation was first distinguished in South Africa in the Mpumalanga and Gauteng territories in May. In June, the new variation was additionally distinguished in KwaZulu-Natal and Limpopo areas and furthermore in pieces of England and China, as per the investigation.

“As of August 13, 2021, the C.1.2 genealogy has been identified in 6/9 South African territories (counting the Eastern Cape and Western Cape), the Democratic Republic of the Congo (DRC), Mauritius, New Zealand, Portugal, and Switzerland,” the examination proceeded.

The C.1.2 variation is proceeding to spread dramatically consistently, scientists said. In May, the C1.2 strain made up about 0.2% of new genomes being sequenced out of South Africa, yet as of July, that rate expanded to 2.0%, “like the increments found in Beta and Delta in South Africa during early discovery,” as per the examination.

The new variation shows comparable spike proteins related with higher paces of contagiousness — similar to the delta variation of the Covid — and might actually have qualities that would permit C.1.2 to sidestep immunization initiated resistant reactions, however, analysts note further perception is required.

As of Aug. 20, there were roughly 80 instances of the C.1.2 Covid variation distinguished in Botswana and South Africa, as indicated by the examination.

The U.S. Communities for Disease Control and Prevention monitors various strains of the novel Covid by ordering them dependent on the strains’ contagiousness and seriousness of sickness.

Strains like alpha, first distinguished in the United Kingdom, beta, first recognized in South Africa, and delta, first recognized in Quite a while, are largely variations of concern.

Variations of concern show “proof of an increment in contagiousness, more extreme illness (e.g., expanded hospitalizations or passings), critical decrease in balance by antibodies produced during past contamination or inoculation, diminished viability of medicines or immunizations, or analytic recognition disappointments,” as per the CDC.

While it is too soon to tell if the C.1.2 variation ought to be sorted as a variation of concern, scientists noticed that it shares large numbers of similar qualities as the alpha, beta and delta variations of the Covid.

Information on a possibly delta-like variation is unwanted as COVID-19 cases keep on averaging at amazingly high numbers in the United States and across the globe, in spite of there being a few endorsed antibodies to battle serious sickness and passing from the novel Covid.

Immunization aversion and postponed endorsement for youngsters to have their chances are adding to a developing number of cases among youngsters and the unvaccinated.

Up until now, about 61% of the qualified populace is immunized against the infection in the U.S.

The current moving seven-day normal of new COVID-19 cases in the U.S. is at 152,246, up from the earlier seven-day normal, which was 146,087, as per CDC information.

In the beyond 24 hours, the U.S. has recorded 154,143 new cases and 1,588 passings brought about by COVID-19, as per Johns Hopkins information.

Fruits High in Protein: A Surprising Nutritional Boost

When thinking of protein sources, fruits might not top the list. However, certain fruits can contribute a surprising amount of this essential macronutrient. While they can’t replace traditional high-protein foods like beans, legumes, or meats, these fruits provide a valuable combination of protein, fiber, vitamins, and antioxidants. Here’s a closer look at protein-rich fruits and their nutritional benefits.

Why is Protein Important?

Protein plays a crucial role in maintaining satiety, tissue repair, and muscle growth. High-protein diets are widely known for aiding weight loss and supporting a healthy lifestyle. Recently, plant-based diets have gained attention for their weight loss benefits and overall health advantages.

Registered dietitian Natalie Rizzo emphasizes that fruit protein should be seen as an addition rather than a primary source. “Every gram of protein counts, especially in a plant-forward diet,” she says. Most people need at least 20 grams of protein per meal, and fruits can be a small yet beneficial contributor.

Protein-Rich Fruits

Here are some fruits that stand out for their protein content, with each providing 1 gram or more per serving.

Passion Fruit

  • Protein: 5 grams per cup of raw fruit
  • Known for its aromatic, jelly-like golden pulp, passion fruit is also rich in fiber, calcium, and vitamins A and C. It can be eaten raw, added to yogurt, or blended into drinks.

Jackfruit

  • Protein: 2.8 grams per cup of raw slices
  • A relative of figs and breadfruit, jackfruit can be eaten ripe as a sweet fruit or unripe as a meat alternative in plant-based dishes.

Pomegranate

  • Protein: 2.9 grams per cup of arils (seeds)
  • Pomegranate seeds are packed with antioxidants, dietary fiber, and anti-inflammatory fatty acids beneficial for heart health.

Apricots

  • Protein: 2.3 grams per cup of fresh slices; 4.4 grams per cup of dried halves
  • This fiber-rich stone fruit also provides antioxidants, iron, and vitamins C, E, B6, and A. Fresh or dried, apricots are a delicious and nutritious snack.

Blackberries

  • Protein: 2 grams per cup of raw fruit
  • Blackberries are rich in antioxidants that may reduce cancer risk and improve gut health due to their high fiber content.

Guava

  • Protein: 1.4 grams per fruit
  • This tropical fruit offers antioxidants, vitamin C, potassium, and fiber. Its sweet-tart flavor makes it versatile for eating raw, blending into smoothies, or making jams.

Raisins

  • Protein: 1.4 grams per 1.5-ounce box
  • Raisins are small but mighty, offering fiber, potassium, and heart health benefits. They make a convenient and nutrient-dense snack, but portion control is key due to their calorie content.

Citrus Fruits

  • Protein: 1.2 grams per orange; 2.3 grams per grapefruit
  • Famous for their vitamin C content, oranges and grapefruits also deliver fiber, potassium, and hydration while being low in calories.

Cantaloupe

  • Protein: 1.3 grams per cup of cubed fruit
  • A standout for its high vitamin A content, cantaloupe provides 40% of the daily recommended intake per cup. It’s an excellent addition to fruit salads, smoothies, or desserts.

Incorporating Fruits Into a Protein-Rich Diet

While fruits shouldn’t be relied on as a primary protein source, they can complement a balanced diet rich in beans, nuts, seeds, and other plant-based proteins. Their added benefits—like vitamins, antioxidants, and fiber—make them a healthy, versatile choice.

Whether you’re blending blackberries into a smoothie, topping yogurt with passion fruit pulp, or snacking on a handful of raisins, these protein-rich fruits are a simple way to enhance your diet while satisfying your sweet tooth.

Coffee and Tea Drinking May Reduce the Risk of Some Cancers: Research

Published

on

Drinking a cup of Joe or some tea for the holidays may be a good thing!

A study reviewed in the journal of the American Cancer Society found that people who drink either tea or coffee have a slightly lower risk of head and neck cancers, though it remains unclear if the drinks themselves directly reduce the risk.

Researchers analyzed data from 14 individual studies involving over 9,500 people with head and neck cancers and over 15,000 people without, compiled by the International Head and Neck Cancer Epidemiology Consortium.

The findings showed that individuals who drank less than four cups of caffeinated coffee daily and less than a cup of tea had a 17% and 9% lower chance, respectively, of developing head or neck cancer overall.

The study also highlighted that coffee drinkers had a reduced risk of developing oral cavity and oropharyngeal cancers located in the middle part of the throat, according to Yale Medicine. Meanwhile, tea drinkers who consumed less than a cup daily showed a lower risk of hypopharyngeal cancer, which affects the bottom part of the throat, per Johns Hopkins Medicine.

“While there has been prior research on coffee and tea consumption and reduced risk of cancer, this study highlighted their varying effects with different sub-sites of head and neck cancer, including the observation that even decaffeinated coffee had some positive impact,” said Dr. Yuan-Chin Amy Lee, senior author of the study from Huntsman Cancer Institute and the University of Utah School of Medicine, as reported by The Guardian.

“Perhaps bioactive compounds other than caffeine contribute to the potential anti-cancer effect of coffee and tea,” Lee added.

However, drinking more than one cup of tea daily was linked to a higher risk of laryngeal cancer, which forms in the larynx, the part of the throat responsible for controlling the vocal cords, according to the National Cancer Institute (NCI).

The study also acknowledged limitations, as participants self-reported their findings and were not asked about the specific types of tea or coffee consumed. Additional unaccounted factors may have influenced the results as well.

“In observational studies, it is very difficult to totally eliminate confounding effects, for example, of tobacco and alcohol from the statistical analysis,” Tom Sanders, a professor emeritus of nutrition and dietetics at King’s College London, told The Guardian.

“Consequently, people who drink a lot of coffee and tea may be more likely to avoid other harmful behaviors such as drinking alcohol and using tobacco and so may be at a lower risk of these cancers for other reasons,” added Sanders, who was not involved in the study.

How the brain makes complex judgments based on context

Published

on

We frequently face difficult choices in life that are impacted by a number of variables. The orbitofrontal cortex (OFC) and the dorsal hippocampus (DH) are two key brain regions that are essential for our capacity to adjust and make sense of these unclear situations.

According to research conducted by researchers at the University of California Santa Barbara (UCSB), these regions work together to resolve ambiguity and facilitate quick learning.

Decision-making that depends on context

The results, which were released in the journal Current Biology, offer fresh perspectives on how certain brain regions assist us in navigating situations that depend on context and modifying our behavior accordingly.

According to UCSB neuroscientist Ron Keiflin, senior author, “I would argue that that’s the foundation of cognition.” That’s what prevents us from acting like mindless machines that react to stimuli in the same way every time.

“Our ability to understand that the meaning of certain stimuli is context-dependent is what gives us flexibility; it is what allows us to act in a situation-appropriate manner.”

Decision-making context

Think about choosing whether or not to answer a ringing phone. What you say depends on a number of variables, including the time of day, who might be calling, and where you are.

The “context,” which influences your choice, is made up of several components. The interaction between the OFC and DH is what gives rise to this cognitive flexibility, according to Keiflin.

Planning, reward valuation, and decision-making are linked to the OFC, which is situated directly above the eyes, whereas memory and spatial navigation depend on the DH, which is positioned deeper in the brain.

According to Keiflin, both areas contribute to a mental representation of the causal structure of the environment, or a “cognitive map.” The brain can model outcomes, forecast outcomes, and direct behavior thanks to this map.

Despite their significance, up until now there had been no systematic testing of the precise functions of these regions in contextual disambiguation, which determines how stimuli alter meaning based on context.

Contextualizing auditory stimuli

In order to find out, the researchers created an experiment in which rats were exposed to aural cues in two distinct settings: a room with bright lighting and a chamber with no light. There was a context-dependent meaning for every sound.

For instance, one sound indicated a reward (sugar water) only when it was light, and another only when it was dark.

The rats eventually learnt to link each sound to the appropriate context, and in one situation they showed that they understood by licking the reward cup in anticipation of a treat, but not in the other.

The OFC or DH was then momentarily disabled during the task by the researchers using chemogenetics. The rats’ ability to use context to predict rewards and control their behavior was lost when the OFC was turned off.

Disabling the DH, however, had minimal effect on performance, which was unexpected considering its well-established function in memory and spatial processing.

Enhanced learning from prior knowledge

For learning new context-dependent interactions, the DH proved essential, but it appeared to be unnecessary for recalling previously learned ones.

“If I walked into an advanced math lecture, I would understand – and learn – very little. But someone more mathematically knowledgeable would be able to understand the material, which would greatly facilitate learning,” Keiflin explained.

Additionally, the rats were able to pick up new relationships far more quickly after they had created a “cognitive map” of context-dependent interactions. The duration of training decreased from more than four months to a few days.

Brain areas cooperating

By employing the same chemogenetic strategy, the researchers discovered that the rats’ capacity to use past information to discover new associations was hampered when the OFC or DH were disabled.

While the DH allowed for the quick learning of novel context-dependent relationships, the OFC was crucial for using contextual knowledge to control immediate action.

This dual role emphasizes how these brain regions assist learning and decision-making in complementary ways.

Education and neuroscience Implications

According to Keiflin, neuroscience research frequently overlooks the well-established psychological and educational theories that prior information affects learning.

Knowing how the brain leverages past information to support learning could help develop educational plans and therapies for people who struggle with learning.

The study clarifies the different functions of the DH and OFC as well. In order to acquire new relationships, the DH is more important than the OFC, which aids in behavior regulation based on contextual knowledge.

These areas work together to help the brain adjust to complicated, dynamic surroundings.

Brain’s Capacity to make Decisions based on context

The study emphasizes how crucial contextual knowledge is for managing day-to-day existence. Human cognition is based on the brain’s capacity to resolve ambiguity, whether it be while choosing whether to answer a ringing phone or when adjusting to new knowledge.

This work highlights the complex processes that facilitate learning and decision-making while also advancing our knowledge of brain function by elucidating the functions of the OFC and DH.

This information creates opportunities to investigate the potential roles that disturbances in these systems may play in disorders like anxiety or problems with decision-making.

Since this type of learning is most likely far more reflective of the human learning experience, Keiflin stated that “a better neurobiological understanding of this rapid learning and inference of context-dependent relations is critical, as this form of learning is probably much more representative of the human learning experience.” 

The results open the door for future studies on the interactions between these brain areas in challenging, real-world situations, which could have implications for mental health and education.
