Researchers have reported the critical role of the level of oxygen in the placenta in the growth of the human brain during the last trimester of the development of foetus.&nbsp;

Scientists underscored the placenta's pivotal role as a mediator between maternal health and foetal brain health.

Emma Duerden, Canada Research Chair in Neuroscience &amp; Learning Disorders at Western University and a scientist at Lawson Health Research Institute led an interdisciplinary team in a study that deployed Magnetic Resonance Imaging (MRI) for the study.

The research, published in the JAMA Network Open, builds upon previous findings correlating placental health and childhood cognition.

The study's innovative approach to imaging placental growth could pave the way for early interventions and therapies for neurodevelopmental disorders. The placenta, a crucial organ during pregnancy, serves as the primary conduit for oxygenation and nutrients to the foetus.

Lead author Emily Nichols, a research scientist said: "If there is anything wrong with the placenta, the foetus might not be receiving the nutrients or the levels of oxygenation it needs to thrive."

Factors such as poor nutrition, smoking, substance use, chronic hypertension, anaemia, and diabetes may lead to foetal growth restriction, affecting approximately six per cent of all pregnancies globally.

Duerden further said, "An unhealthy placenta can place babies at risk for later life learning difficulties or even neurodevelopmental disorders."

Scientists discover how placenta’s role in brain development is linked to child cognition

Scientists have successfully demonstrated the potential of using nasal drops containing a specific molecule to aid in the recovery of mice from the detrimental effects of a stroke.

The promising aspect of this treatment is that it can be administered seven days after the stroke occurs, offering hope that individuals who cannot receive immediate assistance can still benefit from protection against the severe consequences of the condition, according to Science Alert.

<h2>Research replicates positive results</h2>

The crucial component of these drops is a complement peptide called C3a, consisting of a sequence of amino acids, which has been recognised for its significant role in the immune system and the brain's development and adaptability. The ultimate goal is to transfer this treatment to humans, potentially revolutionizing stroke recovery methods.

"With this method, there's no need to race against the clock,"&nbsp;neuro-immunologist Marcela Pekna from the University of Gothenburg in Sweden told Science Alert.

"If the treatment is used in clinical practice, all stroke patients could receive it, even those who arrive at the hospital too late for thrombolysis or thrombectomy. Those who have remaining disability after the clot is removed could improve with this treatment too," he added.&nbsp;

Also read |&nbsp;<a href="https://www.wionews.com/science/scientists-find-cause-of-morning-sickness-in-pregnant-women-605503">Scientists find cause of 'morning sickness' in pregnant women</a>

The intentional delay in the administration of the C3a peptide is crucial due to its potential to amplify the presence of inflammatory cells in the brain, which can have detrimental effects instead of beneficial ones if applied too early.

To investigate its effectiveness, scientists simulated an artificial ischemic stroke, the most prevalent type of stroke, in mice. After a week, the mice treated with nasal drops exhibited significantly improved motor function recovery compared to a control group that received a placebo.

This finding highlights the promising potential of the nasal drops in facilitating faster and more comprehensive recovery from strokes.

The recent study provides valuable insights into the impact of C3a on the brain. Utilizing MRI scans, researchers discovered that the peptide effectively enhanced the formation of neural connections among nerve cells in the mice's brains. This finding contributes to a deeper understanding of the neurological effects of C3a and its potential role in promoting neural connectivity.

"Our results show that the C3a peptide affects the function of astrocytes – that is, cells that control many of the nerve cells' functions in both the healthy and the diseased brain – and which signals astrocytes send to nerve cells,"&nbsp;neuroscientist Milos Pekny from the University of Gothenburg said.

The current study builds upon previous research conducted by the same group of scientists, which investigated the protective and restorative effects of the C3a peptide in relation to stroke damage. The successful replication of their findings underscores the potential of this specific approach.

Ischemic strokes affect a significant number of individuals each year, with a considerable portion experiencing physical or cognitive impairments such as loss of voluntary movement, speech difficulties, and mental health issues like depression and anxiety.

The utilization of nasal drops containing the C3a peptide holds the potential to make a substantial impact on these statistics. However, further investigation is necessary to ensure the viability of this treatment in humans, as it has thus far been demonstrated in mice. This approach adds to the growing list of potential options that researchers are exploring to address the effects of strokes.

Nasal drops show remarkable promise in stroke recovery, study finds

Mothers and fathers who talk to their newborns or toddlers, unknowingly help boost their brain development, research conducted by the University of East Anglia has found. Yes, you read that right! The simple act of speaking to your little munchkin helps shape their developing brain.

Researchers from the UEA studied thousands of hours of language data of babies and toddlers wearing small recording devices while carrying out MRI scans to study the structure of their developing brains.&nbsp;During the research, they found that two-and-a-half-year-olds, who listened to more speech in everyday life, had more myelin in language-related areas of their brains, which researchers said is "likely to support more sophisticated language processing".

Myelin is a material that forms around nerves and allows electrical impulses to transmit quickly and efficiently.&nbsp;

The study involved 163 babies and toddlers and demonstrated how speaking to your little ones can help develop their brains.&nbsp;Their findings were first published in the Journal of Neuroscience.

"We know that children’s brains develop very rapidly in the first two years of life, with brain volume at about 80 per cent that of an adult brain by the age of two," lead researcher Prof John Spencer from UEA's School of Psychology&nbsp;shared. "Myelin is made up of protein and fatty substances and forms an insulating layer around nerves in the brain."

Explaining what exactly is Myelin and how it helps with brain development, Spencer said,&nbsp;"Imagine you have a hosepipe with lots of holes in it. Myelin is like wrapping the hosepipe with duct tape - it insulates neural fibres, bringing more of the 'signal'&nbsp;from one brain area to the next."

The UEA study is one of the first to show that listening to speech is closely linked with early brain development. Spencer added, "Prior work showed a similar association in four to six-year-olds, but our findings push this association much earlier in development. Indeed, we even found associations between language input and brain structure in six-month-old infants."

"Although there is still much more to learn about these processes, the message to caregivers is clear – talk to your baby, your toddler, your child. Not only are they listening, but your language input is literally shaping their brains," the researcher concluded.
