When you're just starting out in the world of healthcare, whether as a nursing student, medical trainee, or phlebotomy learner, few things feel as nerve-racking as your first needle insertion. You've read the textbooks, watched the tutorials, and maybe even practiced on an orange or a banana, but when it comes to human skin, confidence often lags behind theory. This guide is for you - the ...
Ultraviolet (UV) radiation constitutes a portion of the sun's electromagnetic spectrum that poses significant risks to human skin. This invisible radiation is classified into three distinct categories based on wavelength and potential for damage. ...
Human dermal fibroblasts-neonate (HDF-n) are specialized cells derived from the dermis layer of neonatal human skin. These fibroblasts play a crucial role in skin structure, function, and repair. They are pivotal in the study of dermatological conditions, regenerative medicine, and tissue engineering. Role and Functionality Fibroblasts are the primary cells responsible for synthesizing ...
If you’ve ever studied the causes of a skin complaint or damaged hair, chances are someone on the internet has pointed the finger at SLS, or sodium lauryl (or laureth) sulfate, a common ingredient in beauty products, washes, toothpastes and even cleaning products.So what does this ingredient do, why is it in everything, and what does the evidence say about how safe it ...
Collagen is a crucial structural protein, widely presenting in human skin, bones, tendons, ligaments, and other tissues. It's essential for maintaining the structural integrity and function of tissues. The measurement of collagen can help researchers and physicians understand the pathological process of related diseases (such as osteoporosis, arthritis, skin aging etc.), and also aid in drug ...
Collagen is an important protein that is widely present in various human tissues, such as skin, bones, muscle tendons, and ligaments. Accurate determination of its concentration is crucial for multiple fields such as biomaterial research, food industry, and pharmaceutical research.Liquid Chromatography (LC) is an efficient and precise analytical technique for collagen concentration measurement, ...
It is well understood that the Earth’s resources are finite and in recent years consumers have become more environmentally conscious. This has driven the demand for cosmetics and beauty products to be as natural as possible but without having a negative impact on the planet. As a result of this, biotechnology has seen a surge in popularity within the beauty industry, driven by its sustainable ...
Strongyloides is an opportunistic pathogenic parasitic nematode. Adults parasitize in the small intestine of cats, dogs and humans. The larvae can invade lung, brain, liver, kidney and other tissues and organs, causing strongyloidiasis. The disease is mainly prevalent in warm and humid tropical and subtropical regions. In recent years, due to the continuous increase of HIV/AIDS infection rate in ...
Collagen is a family of proteins. At least 30 kinds of genes encoding collagen chains have been found, which can form more than 16 kinds of collagen molecules. According to its structure, it can be divided into fibrous collagen, basement membrane collagen, microfibrillar collagen, anchored collagen, hexagonal reticular collagen, non-fibrous collagen, transmembrane collagen, etc. According to ...
Some substances can easily interact with the oxygen in the air when exposed to the air, causing chemical changes in the substance. This is the process of oxidation. Sun exposure, air pollution, radiation, etc. will cause the human skin to produce a large amount of superoxide free radicals, and its strong oxidizing ability will accelerate the speed of skin oxidation, and may even cause serious ...
You've probably heard amazing stories of surgeons performing successful, yet extremely delicate and risky procedures such as open-heart surgery, separation of conjoined twins, craniotomy, thoracic aortic dissection repair, oesophagectom, spinal osteomyelitis surgery, and many more. As a medical student, you wonder how a surgeon can do such an incredible job. Well, the answer lies in lots of ...
If you're a medical student and you're trying to take your skills to the next level, you might be wondering how to practice suturing so that you can do it more effectively in a hospital setting. Fortunately, education has come a long way when it comes to effectively teaching students how to do such things. However, that doesn't mean that you might not need some extra practice on your own in order ...
On August 26, 2019, the National Institute of Environmental Health Sciences (NIEHS) announced that the results of an NIEHS-funded study show that graphene could provide alternatives to chemicals in insect repellant and protective clothing. The study, “Mosquito Bite Prevention through Graphene Barrier Layers,” was published in the Proceedings of the National Academy of Sciences. ...
Abstract Summary Polyetheretherketone (PEEK) is an alternative to metallic implants in orthopedic applications; however, PEEK is bioinert and does not osteointegrate. In this study, an accelerated neutral atom beam technique (ANAB) was employed to improve the bioactivity of PEEK. The aim was to investigate the growth of human mesenchymal stem cells (hMSCs), human osteoblasts (hOB), and skin ...
Skin pigmentation variations and discolorations can appear in the form of various dark spots, due to age, acne scars or other conditions, or obtained as a result of the overexposure to the sun’s harmful UV rays. Sometimes freckles, the small dots of highly concentrated skin pigmentation, could also be undesirable. Skin whitening, lightening and bleaching refer to the use of chemical ...
BioLargo Inc. (OTCBB: BLGO), a company focused on leveraging Nature’s Best Solution® - iodine– to solve a variety of common problems around the world, operating in industries dominated by giants such as Chemtura Corp (NYSE: CHMT) and Polypore International Inc. (NYSE: PPO), also looks to have an important and potentially significant play in the wound management industry which ...
Sildenafil citrate (SC) is the first choice drug for erectile dysfunction. Nevertheless, drug oral delivery is hampered by some obstacles including first pass metabolism, numerous side effects, relatively short duration and long onset of action. Furthermore, drug delivery formulation and transdermal application of SC is challenged by its amphoteric nature, low oil and water solubility, ...
Skin colour is an important feature for face detection and recognition in colour images. To obtain the possible face regions in colour images, skin colour models are always constructed by statistical analysis. Owing to low accuracy of the static models, researchers have discussed several dynamic models to correct input images. Unfortunately, it is possible that some objects whose colour is the ...
Cationic biocides (CBs) are widely used in domestic and public hygiene and to control biofouling and microbial contamination in industry. The increased use of biocides has led to concern regarding possible reductions in biocide effectiveness. Domestic drain microcosms were stabilized for 5 months and then exposed to polyhexamethylene biguanide (PHMB) at 0.1, 0.2, and 0.4g liter–1 over 6 months ...
