The BCG vaccine protects against tuberculosis, but by inducing trained immunity it also protects against many more respiratory infections. International research led by Radboud University Medical Center shows how this process works. Lactate, a product of scaled-up energy production, appears to play a leading role.

The immune system protects people in two ways. Innate immunity protects us from birth against many bacteria and viruses, while adaptive immunity builds protection against individual pathogens after a prior infection. The adaptive immune system is aided by vaccines that protect us against new pathogens without having to go through an infection. In this way, vaccines contribute greatly to our health.

Results of a large, global clinical trial spanning five continents with over 1,700 patients with bronchiectasis, published this April in the New England Journal of Medicine, demonstrated benefits of an investigational, once-a-day pill called brensocatib as a therapy for the chronic lung condition.

The clinical trial findings are important, as there are currently no FDA-approved medications for bronchiectasis, a chronic condition with persistent lung airway inflammation and infection. Bronchiectasis can often stem from various injuries to the airways causing the ‘bronchial’ tubes leading to the lungs to become permanently enlarged, and more prone to infection and chronic inflammation.

In this Review, the authors discuss mass spectrometry (MS) imaging and spatially resolved MS approaches that are being employed in nephrology applications. They also highlight emerging MS methods and applications, as well as the integration of MS data with data from other omics approaches.

Mitochondrial diseases affect approximately 1 in 5,000 people worldwide, causing debilitating symptoms ranging from muscle weakness to stroke-like episodes. Some of these conditions result from mutations in mitochondrial DNA (mtDNA), the genetic material housed in these organelles. For patients with the common m.3243A>G mutation, which can cause MELAS syndrome (mitochondrial myopathy, encephalopathy, lactic acidosis, and stroke-like episodes) and diabetes mellitus, treatments remain limited.

Viruses are known to use the genetic machinery of the human cells they invade to make copies of themselves. As part of the process, viruses leave behind remnants throughout the genetic material (genomes) of humans. The virus-like insertions, called “transposable elements,” are snippets of genetic material even simpler than viruses that also use host cell machinery to replicate.

Nearly all these inserted elements have been silenced by our cells’ defense mechanisms over time, but a few, nicknamed “jumping genes,” can still move around the human genome like viruses. Just one, called long interspersed nuclear element 1 (LINE-1), can still move by itself.

As an element type that behaves like the retrovirus HIV, the LINE-1 “retrotransposon” is first copied into a molecule of RNA, the genetic material that partners with DNA, and then the RNA LINE-1 copy is converted back into DNA in a new place in the genome.

Recent advances in robotics and machine learning have enabled the automation of many real-world tasks, including various manufacturing and industrial processes. Among other applications, robotic and artificial intelligence (AI) systems have been successfully used to automate some steps in manufacturing clothes.

Researchers at Laurentian University in Canada recently set out to explore the possibility of fully automating the knitting of clothes. To do this, they developed a model to convert images into comprehensive instructions that knitting robots could read and follow. Their model, outlined in a paper published in Electronics, was found to successfully realize patterns for the creation of single-yarn and multi-yarn knitted items of clothing.

“Our paper addresses the challenge of automating knitting by converting fabric images into machine-readable instructions,” Xingyu Zheng and Mengcheng Lau, co-authors of the paper, told Tech Xplore.
