Accomplished Surgeons Doing Robotic Surgery Recorded a 5X Growth in India

Posted by in categories: biotech/medical, government, health, robotics/AI

As the Indian healthcare sector increasingly adopts robotic surgery, Dr. Mahendra Bhandari, the CEO of the US-based Vattikuti Foundation and a prominent advocate for robotic surgery, highlights the growing presence of various surgical robots from multiple vendors. He underscores the rising number of trained doctors and the commitment of both government and corporate hospitals to invest in surgical robots across the country.

The Vattikuti Foundation, founded by Indian American entrepreneur and philanthropist Raj Vattikuti, serves communities in Michigan, USA, and India. It initiated the Vattikuti Urology Institute at Henry Ford Health in Detroit, Michigan, in 1997 and has since evolved into an international organisation promoting excellence in robotic surgery through various avenues.

In an exclusive interview Dr. Jayati Dubey, DHN, speaks to Dr. Bhandari on the expanding scope of robotic surgery in India.

Alzheimer’s: Exercise-induced hormone may help reduce plaque

Posted by in categories: biotech/medical, health, neuroscience

He added the study may lead doctors to try finding medications to mimic the effect of exercise without actually requiring physical activity.

“While this research shows promising results, a lot more research would be needed to show how much of an impact it would make on people with Alzheimer’s and how much would be needed for a preventive effect,” Voci said. “But I would argue that this gives more evidence to the broad spectrum of what exercise can treat. Exercise is medicine.”

Specialized astrocyte subpopulation discovery sheds light on brain health and treatment avenues

Posted by in categories: health, neuroscience

In a recent study published in Nature, researchers investigated whether glutamatergic gliotransmission was mediated by specialized astrocytes in the central nervous system.

The role of astrocytes in brain circuitry function, such as swift glutamate release, has been questioned due to inconsistent data and lack of direct evidence. This mechanism, similar to neurons, controls plasticity, excitability, and coordinated activity of synaptic-type networks but also contributes to neuropsychiatric conditions.

Nanotechnology-Boosted Biomaterials for Osteoarthritis

Posted by in categories: biotech/medical, chemistry, engineering, health, nanotechnology

Osteoarthritis (OA) is a prevalent global health concern, posing a significant and increasing public health challenge worldwide. Recently, biomaterials have emerged as a highly promising strategy for OA therapy due to their exceptional physicochemical properties and capacity to regulate pathological processes. However, there is an urgent need for a deeper understanding of the potential therapeutic applications of these biomaterials in the clinical management of diseases, particularly in the treatment of OA. In this comprehensive review, we present an extensive discussion of the current status and future prospects concerning biomaterials for OA… More.

Herein, in this review, we summarize the advanced strategies developed for enhancing OA therapy based on the biomaterials. We conducted a comprehensive literature search using relevant databases such as PubMed, Scopus, and Web of Science. The search was focused on peer-reviewed articles and research papers published within the last ten years (from 2013 to 2023). We utilized specific keywords related to biomaterials”, biomaterials” and “osteoarthritis therapy” to retrieve relevant studies. First, we provide an overview of the pathophysiology of OA and the limitations of current treatment options. Second, we explore the various types of biomaterials which have been used for OA therapy, including nanoparticles, nanofibers, and nanocomposites. Third, we highlight the advantages and challenges associated with the use of biomaterials in OA therapy, such as toxicity, biodegradation, and regulatory issues. Finally, advanced biomaterials-based OA therapies with their potential for clinical translation and emerging biomaterials directions for OA therapy are discussed.

Characteristics of Biomaterials

Nanotechnology-boosted biomaterials have attracted considerable attention in recent years as promising candidates for revolutionizing the field of therapeutics.12,13 These materials combine the unique properties of nanotechnology with the versatility and biocompatibility of biomaterials, offering numerous advantages over existing therapeutic approaches. Nanotechnology enables the precise engineering of biomaterials at the nanoscale, allowing for the encapsulation and controlled release of therapeutic agents, such as drugs and growth factors.14–17 This feature facilitates targeted and sustained drug delivery to specific sites within the body, reducing systemic side effects and enhancing treatment efficacy. In the context of OA, this targeted drug delivery can be utilized to deliver anti-inflammatory agents or disease-modifying drugs directly to affected joint tissues, promoting tissue repair and alleviating symptoms. Furthermore, biomaterials can be designed to mimic the native tissue environment, thereby enhancing their biocompatibility and reducing the risk of adverse reactions or immune responses.18 This characteristic is crucial for successful integration and long-term functionality of biomaterials in biomedical applications. Moreover, nanomaterials can facilitate tissue regeneration by stimulating cellular responses and promoting tissue growth.19 In the context of OA, biomaterials can assist in cartilage repair and regeneration, potentially slowing down disease progression and improving joint function.3 In addition, nanotechnology allows for the customization of biomaterials with a wide range of physical, chemical, and biological properties.13 This flexibility enables the development of multifunctional biomaterials that can simultaneously perform multiple tasks, such as drug delivery, imaging, and tissue regeneration. These advantages collectively contribute to their potential as innovative solutions in addressing various biomedical challenges and improving patient outcomes. In this section, we will discuss some of the key properties of biomaterials and their impact on OA treatment.

Scientists use video games to measure the eye-brain-body connection

Posted by in categories: biotech/medical, entertainment, food, health, neuroscience

Video games could give ophthalmologists an easy window not into the soul, but into eye health and the eye-brain-body connection — the three-way reciprocal communication that influences our actions.

“Infusing science into games is like sneaking broccoli into ice cream,” said Khizer Khaderi, MD, a clinical associate professor of ophthalmology. “It removes the resistance to do something that may not be viewed as fun, such as eating vegetables.” Or in this case, evaluating your vision health.

In a Stanford Medicine-led study, researchers employed video games to evaluate participants’ field of vision and visual stamina, their ability to distinguish contrast, and other factors that can indicate common eye diseases.

Exercise-induced hormone irisin may reduce Alzheimer’s disease plaque and tangle pathology in the brain

Posted by in categories: biotech/medical, health, neuroscience

Researchers who previously developed the first 3D human cell culture models of Alzheimer’s disease (AD) that displays two major hallmarks of the condition—the generation of amyloid beta deposits followed by tau tangles—have now used their model to investigate whether the exercise-induced muscle hormone irisin affects amyloid beta pathology.

As reported in the journal Neuron, the Massachusetts General Hospital (MGH)–led team has uncovered promising results suggesting that irisin-based therapies might help combat AD.

Physical exercise has been shown to reduce deposits in various mouse models of AD, but the mechanisms involved have remained a mystery.
