Electro-mechano-optical NMR Detection

Posted on Updated on

NMR is a branch of spectroscopy where scientists measure the spin of an atom’s nucleus in order to determine its identity. Atomic nuclei subjected to a magnetic field induce radio-frequency signals in a detector circuit. Since different atoms cause signals at different frequencies, scientists can use this information to determine the compounds contained in a sample. The most well-known application of this is in MRI-based imagining, such as CT scans.”NMR is a very powerful tool, but its measurements rely on amplification of electrical signals at radio-frequencies. That pulls in extra noise and limits the sensitivity of our measurements,” explains Takeda. “So we developed an experimental NMR system from scratch, which converts radio-frequency signals into optical ones.”

Computed tomography is an imaging procedure that uses special x-ray equipment to create detailed pictures, or scans, of areas inside the body. It is also called computerized tomography and computerized axial tomography.

Medical Devices Access in Asian Countries: Sustainable Growth Trajectory in India

Posted on Updated on

Technologically advanced solutions for treatment of diseases, scientific rigor and research has seen tremendous growth in therapeutic usage of medical devices. The role of ‘Make in India’ initiative becomes of utmost importance as a driving force for technological advancement of medical devices industry. However, challenges exists and need to be addressed in providing affordable healthcare by producing medical devices that are cost competitive and effective to increased access. Asian Countries like Japan, China and South Korea are foremost in the Medical devices sector. This paper probes the sustainability of Make in India policy with the growth trajectory of Asian countries in medical devices discusses ways of overcoming challenges through regulations, policies and other stakeholders contribution.

Mode of Transmission, Outrageous Effects and Clinical Trials

Posted on Updated on

Zika has become one of the most worldwide spreading dangerous infection over the past decade because of its perpetual spread, initially in Asia-Pacific region, followed by its expeditious entry into the Western world. Zika virus was initially discovered in rhesus monkey in the forest of Uganda. But due to Unique genetic recombination in the genome of Zika virus has made the Zika infection more dangerous than the last one. Zika virus can be transmitted through both vector and non-vector means such as mosquito and sexual transmission. Eighty percent patient with Zika virus showed asymptomatic symptoms on the initial stage of disease onset but later symptoms can become severe. Zika has become one of the most dangerous infections of the 21st century because of its association with microcephaly and Guillain-Barre syndrome. Due to the rapid spread of virus WHO declares Zika virus as public health emergency in the end of 2016. There are many methods of early Zika virus diagnosing but the most common method used all over the world is RNA NAT analysis.RT-PCR can also use for the early diagnoses of Zika virus. At this time, clinical trials in different countries are continuing for the development of successful vaccines against Zika until now the most effective vaccine developed against Zika is DNA vaccine due to its effective mechanism of action and high efficacy. Various antiviral drugs against Zika have also approved by FDA. In our review, we emphasize on every aspect of Zika virus from the genetic basis to its effective treatment strategies.

Bed Bug Histamines are Substantial, Persistent in Infested Homes

Posted on Updated on

NC State post-doctoral researcher conducted a Raleigh-based study to compare histamine levels in homes with and without bed bug infestation. The researchers also evaluated the extent to which treatment and time affect those histamine levels.

“Histamine levels in bedbug-infested homes were at least 20 times higher than histamine levels in homes without bed bug.” And these levels didn’t decrease many three months after treating the infested homes with heat and insecticides.”

In humans, histamines are generally released as part of an immune response. They cause inflammation and help allow other immune system chemicals to fight a pathogen or to do cellular repair work. Histamines, though, can have deleterious effects in humans, including rashes when contacted with skin and respiratory problems when inhaled — think of the allergic reactions to certain foods, pollen, mould or other environmental conditions.”

Effects of Differently Processed Rehmannia Roots on Dexamethasone-induced Side Effects in Rats

Posted on Updated on

Background: There are three differently processed Rehmannia roots, namely fresh, dried and steamed Rehmannia roots (FRR, DRR, and SRR), which have different indications according to the theory of traditional Chinese medicine (TCM). Objective: To confirm the effects of different Rehmannia roots on dexamethasone (Dex) treatment induced side effects, which belong to Yin Deficiency Syndrome in TCM. Materials and Methods: Rats were subcutaneously injected with Dex (0.1m g/kg) and orally administrated with different roots (2.16 g/kg) for 28 days, with metformin (Met, 0.25 g/kg) as a reference substance. Food intake, blood cell count, and organ weight were recorded, and hepatic glycogen and serum insulin, glucose, free fatty acids, total cholesterol, and malondialdehyde contents were assayed. Results: Dex treatment led to decreases in food intake, white blood cell count, and spleen index, and increases in hemocrit, heart and liver indexes, hepatic glycogen, and serum contents of insulin, glucose, free fatty acids, total cholesterol, and malondialdehyde. The alterations in food intake, spleen index, hematocrit and serum insulin were significantly relieved by FRR but not DRR and SRR; and on the contrary, heart index was significantly reduced by DRR and SRR but not FRR. Conclusions: Dex treatment results in insulin resistance, high blood viscosity, oxidative damage and immunosuppression in rats, and FRR is better than DRR and SRR in attenuating Dex-induced insulin resistance and high blood viscosity. These findings have thus firstly provided evidence that postharvest processing has a profound influence on the biological activities of Rehmannia roots.
