Selenium Nanoparticles Redefining Postmenopausal Osteoporosis Treatment with a Novel Approach



Selenium Nanoparticles Redefining Postmenopausal Osteoporosis Treatment with a Novel Approach

In a groundbreaking exploration of postmenopausal osteoporosis treatment, researchers at The Hong Kong Polytechnic University, led by Prof. Wong Ka-hing, have introduced a novel approach utilizing selenium nanoparticles (Cs4-SeNPs). This transformative study, showcased in the esteemed Journal of Functional Foods, not only unravels the intricacies of their research methodology but also sheds light on the promising applications of Cs4-SeNPs in addressing the escalating prevalence of postmenopausal osteoporosis.

Understanding Menopause and Osteoporosis

Menopause is a normal part of getting older. It’s when women stop having periods, which usually happens around age 51. Osteoporosis is a slow-moving disease that makes bones more likely to break or fracture. It causes bones to become porous and weak. For many women, menopause is the main cause of osteoporosis. This is because estrogen levels and other hormones change and drop during this normal process.

Global Impact and Research Initiative

Osteoporosis is a big problem for healthcare systems around the world because the world’s population is getting older, and metabolic illnesses are becoming more common. Prof. Wong Ka-hing and his study team have made groundbreaking progress in creating Cs4-SeNPs as a possible way to treat osteoporosis in women after menopause.

Selenium’s Crucial Role in Bone Health

Selenium is an important trace mineral that performs many important physiological processes in the body. It helps keep bones healthy in many ways, including by fighting free radicals, making bones stronger, encouraging osteoblast development, and controlling bone loss.

Innovative Selenium Nanoparticles – Cs4-SeNPs

In a unique move, the researchers used selenium nanoparticles that came from Cordyceps sinensis. Compared to other types of selenium, Cs4-SeNPs are more bioactive and less harmful. Cs4-SeNPs have qualities that make them useful for protecting bones, especially in cases like postmenopausal osteoporosis. For example, they are quickly taken up by bone cells and cause reactive oxygen species to be released, which helps osteoblasts differentiate.

Decades of Research and Selenium Deficiency

Decades’ worth of study has highlighted the detrimental effects of selenium shortage on bone microarchitecture, connecting it with osteoporosis and highlighting the role of selenium in bone metabolism. Due to their extraordinary bioactivity and decreased toxicity compared to conventional seleno compounds found in foods, selenium nanoparticles (SeNPs) have arisen as a focus of scientific investigation in recent years.

Innovative Process – From Cordyceps sinensis to Cs4-SeNPs:

Cordyceps sinensis is a medicinal fungus that is widely used because of its tonic and therapeutic characteristics. The researchers made strategic use of this fungus. They were able to successfully develop Cs4-SeNPs with a uniform structure and great stability by first separating polysaccharide–protein complexes (PSPs) from the C. sinensis mycelium (Cs4) and then applying nanotechnology that was patented by them.

Efficiency of Cs4-SeNPs – Insights from Cell Studies:

The effectiveness of Cs4-SeNPs was investigated by conducting experiments on pre-osteoblast murine MC3T3-E1 cells, which revealed important new insights. The cells were able to quickly and efficiently take up these nanoparticles, which led to an increase in cell proliferation and the encouragement of their differentiation into mature osteoblasts. In addition, the researchers found evidence of improved bone mineralization, which is suggestive of a beneficial effect that Cs4-SeNPs have on the production of new bone.

In conclusion, researchers at The Hong Kong Polytechnic University have pioneered a ground-breaking remedy for postmenopausal osteoporosis by making use of selenium nanoparticles called Cs4-SeNPs. Osteoporosis is a condition that presents an increasing problem to the world’s various healthcare systems as the world’s population ages. Cordyceps sinensis and patented nanotechnology are being used by the team to develop Cs4-SeNPs, which have greater bioactivity and reduced toxicity in comparison to typical selenocompounds.
This innovative process is being led by Professor Wong Ka-hing. Experiments conducted both in vitro and in vivo indicate the effectiveness and potential of Cs4-SeNPs in boosting bone health. These findings open up new paths for health promotion and disease prevention that go beyond the care of postmenopausal osteoporosis.

Blue tongue Alert: Norfolk Livestock Farmers Navigate New Challenges



Blue tongue

Expanding Control Zones: Norfolk’s Battle Against Blue tongue Outbreak

Norfolk’s livestock farming community faces a heightened challenge as the bluetongue control zone expands in response to new cases of this potentially fatal animal disease. Bluetongue, affecting ruminants such as cattle, sheep, goats, deer, and camelids, has raised concerns after the confirmation of two infected cattle on a holding near Norwich. The total number of cases in the county has now reached 21 since the initial discovery on a Cantley farm in the Broads on December 8, signaling the need for increased vigilance and control measures.

 Blue tongue

The regulatory authority in charge of such matters, the Department for Environment, Food & Rural Affairs (Defra), recently confirmed the extension of the temporary control zone (TCZ) in response to the latest developments. This 10-kilometer zone was initially established to facilitate focused surveillance efforts and restrict livestock movements, aiming to prevent the disease’s further spread. All preceding cases were contained within the TCZ, but the most recent instances involved animals grazing just outside the zone during a high-risk period. Consequently, the TCZ’s boundaries have been adjusted, extending it toward Norwich to address this evolving situation effectively.

An interesting departure from previous protocol is the decision not to cull the infected animals this time. Defra has opted for an alternative approach, restricting these animals at their current locations and implementing disease mitigation measures. This strategic shift is attributed to a recent reduction in midge activity, diminishing the risk of onward transmission. The link between bluetongue and infected midges is crucial to understanding its spread, as it is believed that the disease was introduced to Norfolk and Kent by these tiny vectors, carried across the Channel from Europe during optimal wind and temperature conditions in September or October.

However, despite the absence of evidence suggesting the disease’s circulation through midges in the UK, precautionary measures within the TCZ are causing disruption and uncertainty for local livestock farms. Specific licenses are now mandatory for moving animals out of the zone, with permission granted only under circumstances of “urgent and genuine welfare need” or for direct transportation to a designated abattoir. This has added an extra layer of complexity for farmers who must navigate these restrictions while ensuring the well-being of their livestock.

In conclusion, the expansion of the bluetongue control zone in Norfolk reflects the ongoing challenges in managing and preventing the spread of this disease. The decision to extend the TCZ, along with the nuanced approach to handling infected animals, showcases the dynamic nature of the situation. Livestock farmers must now contend with both the immediate implications of the disease and the regulatory hurdles imposed by specific licenses, emphasizing the need for a coordinated and adaptive response to safeguard the region’s agricultural interests. Stay informed, stay vigilant, and adhere to the evolving guidelines to ensure the well-being of both animals and the farming community
