Bodybuilding supplement helps prevent Alzheimer’s disease

Posted by in categories: biotech/medical, neuroscience

There’s an exciting new development in the field of Alzheimer’s disease research. Surprisingly, it centers around a common bodybuilding supplement known as HMB. The key to preserving memory and staving off this devastating disease may, in fact, reside in the diet of those pumping iron at the gym.

Researchers from RUSH Medical College have recently revealed that the muscle-enhancing supplement known as beta-hydroxy beta-methylbutyrate (HMB) could hold potential in the fight against Alzheimer’s disease.

The supplement, frequently used by bodybuilders to boost muscle growth and enhance performance, might also aid in memory protection, plaque reduction, and slowing the progression of Alzheimer’s disease.

Social genetic effects: Study suggests your romantic partner’s DNA can influence your own health behaviors

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

New research provides evidence that an individual’s health behaviors and outcomes are influenced by the genetic makeup of their romantic partner. The findings, published in Behavior Genetics, indicate that your partner’s genetic tendencies can lead to changes in your own weight, smoking habits, or alcohol consumption over time.

The researchers conducted this study to investigate how a person’s partner can affect their health. They aimed to explore the concept of social genetic effects, which refers to the impact of genetic factors in one person’s environment, such as their partner’s genotype, on their own phenotype (observable characteristics or traits).

“I was mainly interested in exploring the combination of social science and genetics,” explained study author Kasper Otten of Utrecht University. “It is evident that behavior is partly genetically influenced, but much of the social sciences does not deal with this biological fact.

Milk Proteins—Their Biological Activities and Use in Cosmetics and Dermatology

Posted by in categories: biotech/medical, chemistry, food

Milk and colostrum have high biological potential, and due to their natural origin and non-toxicity, they have many uses in cosmetics and dermatology. Research is ongoing on their potential application in other fields of medicine, but there are still few results; most of the published ones are included in this review. These natural products are especially rich in proteins, such as casein, β-lactoglobulin, α-lactalbumin, lactoferrin, immunoglobulins, lactoperoxidase, lysozyme, and growth factors, and possess various antibacterial, antifungal, antiviral, anticancer, antioxidant, immunomodulatory properties, etc. This review describes the physico-chemical properties of milk and colostrum proteins and the natural functions they perform in the body and compares their composition between animal species (cows, goats, and sheep). The milk-and colostrum-based products can be used in dietary supplementation and for performing immunomodulatory functions; they can enhance the effects of certain drugs and can have a lethal effect on pathogenic microorganisms. Milk products are widely used in the treatment of dermatological diseases for promoting the healing of chronic wounds, hastening tissue regeneration, and the treatment of acne vulgaris or plaque psoriasis. They are also increasingly regarded as active ingredients that can improve the condition of the skin by reducing the number of acne lesions and blackheads, regulating sebum secretion, ameliorating inflammatory changes as well as bestowing a range of moisturizing, protective, toning, smoothing, anti-irritation, whitening, soothing, and antiaging effects.

Keywords: milk, colostrum, casein, β-lactoglobulin, α-lactalbumin, lactoferrin, growth factors, skin, regeneration, antimicrobial, cosmetics.

Although milk is known to be used as a raw material in the food industry, it is also widely used in the pharmaceutical and cosmetic industries due to its considerable biological potential. It has also been the subject of detailed analyses and discussions of its individual components and their properties [1, 2].

Metasurface enables strong coupling effects between light and transition metal dichalcogenides

Posted by in categories: energy, nanotechnology

The interaction of light and matter on the nanoscale is a vital aspect of nanophotonics. Resonant nanosystems allow scientists to control and enhance electromagnetic energy at volumes smaller than the wavelength of the incident light. As well as allowing sunlight to be captured much more effectively, they also facilitate improved optical wave-guiding and emissions control. The strong coupling of light with electronic excitation in solid-state materials generates hybridized photonic and electronic states, so-called polaritons, which can exhibit interesting properties such as Bose-Einstein condensation and superfluidity.

Low-tech secret handshake box tests 99.9% effective against car theft

Posted by in categories: security, transportation

With US car thefts up 25.1% since 2019, it’s clear that high-tech key fob immobilizers aren’t cutting the mustard. But this might: UMich researchers have created a charmingly low-tech anti-theft device that turns the whole car into a security keypad.

Keyless entry and ignition are a brilliant step up in convenience from the old “stick key in hole and turn” method of starting cars, but thieves and hackers with a bit of know-how and some specialist gear are finding late-model keyless cars quick and easy to break into and steal. Between this kind of thing and Tik Tok car theft challenges, criminals are having a field day in the post-COVID era.

A team at the University of Michigan has come up with a fun solution that doesn’t use wireless signals at all. The “Battery Sleuth,” as they’ve called it, sits between the car’s battery and its electrical system, and measures fluctuations in voltage, looking for a specific set of voltage changes that act as a secret handshake of sorts between driver and car. Only when this handshake is complete will the device let the full power of the battery through to fire up the starter motor.

Researchers grow precise arrays of nanoLEDs

Halide perovskites are a family of materials that have attracted attention for their superior optoelectronic properties and potential applications in devices such as high-performance solar cells, light-emitting diodes, and lasers.

5 SLE Patients See Disease Remission With CAR T-cell Therapy

Posted by in category: biotech/medical

A CAR T-cell therapy targeting disease-driving immune cells safely led to sustained disease remission for five people with systemic lupus erythematosus (SLE) who’d previously failed to respond to other treatments, a recent study reported.

Treatment was also highly specific, preventing autoimmune activity, but didn’t impair general immune system function.

“These data provide new therapeutic possibilities to control SLE disease activity,” the researchers wrote. “Longer follow-ups in larger cohorts of patients will be necessary to confirm sustained absence of autoimmunity and resolution of inflammation in patients with SLE who have received CAR T cell therapy.”

Vaccine delivers a boost to T cell therapy

Posted by in categories: biotech/medical, engineering

Engineering T cells to destroy cancer cells has shown success in treating some types of cancer, such as leukemia and lymphoma. However, it hasn’t worked as well for solid tumors.

One reason for this lack of success is that the T cells target only one antigen (a target protein found on the tumors); if some of the tumor cells don’t express that antigen, they can escape the T cell attack.

MIT researchers have now found a way to overcome that obstacle, using a vaccine that boosts the response of engineered T cells, known as chimeric antigen receptor (CAR) T cells, and also helps the immune system generate new T cells that target other tumor antigens. In studies in mice, the researchers found that this approach made it much more likely that tumors could be eradicated.

Relationship among bats, parasitic bat flies, and associated pathogens in Korea

Posted by in categories: biotech/medical, health

Conclusions.

The vectorial role of bat flies should be checked by testing the same pathogen and bacterial organisms by collecting blood from host bats. This study is of great interest in the fields of disease ecology and public health owing to the bats’ potential to transmit pathogens to humans and/or livestock.

Covid is a bat bourne disease from such zoonotic transmission.
