This survey describes experiences of patients utilizing blenderized tube feeding (BTF) or commercial (CBTF) via jejunostomy tubes (J tube) as reported by registered dietitians/nutritionists (RDNs). RDNs were electronically recruited to complete a 23-item regarding in their clinical practice (past present) who utilized BTF. Compared formula (CF) feeding, after weaning fed J BTF, reductions nausea, vomiting, diarrhea, bloating/gas, pain, and improved growth/weight goals. Reports outcomes BTF...
The nature and magnitude of molecular interactions on hair surfaces underpin the design formulated products, which application involves a competitive adsorption process between cationic surfactants, fatty alcohols surface actives such as silicone. knowledge interaction with will not only provide insight binding affinity but also offer an effective methodology in characterizing deposits.
Coherent anti-Stokes Raman scattering (CARS) microscopy is used to determine the distribution and concentration of selected compounds in intact human hair. By generating images based on ratiometric CARS contrast, quantitative maps both water externally applied d-glycine are produced cortex hair fibers. Both found homogeneously distribute throughout cortical regions The ability selectively detect molecular agents fibers direct relevance understanding chemical physical mechanisms that underlie...
Abstract Purpose Nirmatrelvir/ritonavir is one of few options for outpatient treatment COVID-19, but its use has been limited in transplant recipients due to significant drug interactions with immunosuppressants. Tacrolimus toxicity possible when the coadministered nirmatrelvir/ritonavir and may require urgent reduction tacrolimus levels. This case series describes phenytoin enzyme induction 5 adult solid organ supratherapeutic levels resulting from coadministration nirmatrelvir/ritonavir....
During hair coloring a number of disulfide bonds in cystine are oxidized (1) to create cysteic acid, forming binding sites for metal ions such as Ca(2+ )and Cu(2+ )from tap water (2). The increased uptake these metals can have detrimental impact on fiber properties-for example, reducing shine and causing poor wet dry feel (3). In addition, the copper also contribute further damage during subsequent due its ability take part metal-induced radical chemistry (4). It is important know where...
Autocatalytic Fenton-like decomposition of hydrogen peroxide in the presence Cu(<sc>ii</sc>) and etidronic acid (HEDP) at high pH results nucleation very stable mixed copper(<sc>ii</sc>) phosphate/carbonate nanoparticles which self-inhibit further reaction.
Synopsis Objective Damage to hair from UV exposure has been well reported in the literature and is known be a highly complex process involving initiation via absorption of light followed by formation propagation reactive oxygen species ( ROS ). The objective this work was understand these mechanisms, explain role copper accelerating identify strategies reduce damage caused species. Methods location measured Transmission electron microscopy–( TEM ) X‐ray energy dispersive spectroscopy XEDS...
The objective of this work was to identify whether low levels redox metals such as copper will accelerate damage hair on exposure UV irradiation and can be prevented.The methods used were proteomics measure the protein via loss after different periods mass spectroscopy specific marker peptides that are specifically created by type damage.In work, we have developed new insights into mechanism using these proteomic methods. A fragment in extract identified (m/z = 1279) is unique increases with...
The objective of this work was to create a shampoo formula that contains stable ordered gel network structure delivers fatty alcohols inside hair.X-ray diffraction (SAXS and WAXS), SEM DSC have been used confirm formation the Lβ with alcohol (cetyl stearyl alcohols) an anionic surfactant (SLE1S). Micro-autoradiography extraction methods using GC-MS were penetration into hair, cyclic fatigue testing measure hair strength.In work, evidence created from cetyl (SLE1S) is presented, confirmed via...
Human hair can extract significant levels of calcium and magnesium, water hardness metals, from tap immediately following chemical treatments during hygiene practices. We have previously shown that this uptake is primarily a function the condition hair. Depending on extent damage, notable amounts metals even soft water. As concentrate in cuticle layers fibre, it hypothesized their presence will affect structural properties are chiefly driven by cuticle. examined mechanics styling technical...
Protein oxidative degradation is implicated in a wide range of deleterious effects. For human hair, this damage can lead to significant observable changes fiber physical and visual properties. A redox proteomic approach was applied map molecular modification hair proteins correlate with the abundance copper (II) ions, levels UV exposure general level pigmentation. An increase observed increasing ion levels, regardless pigmentation level. Significantly, increased protein also occur both...
Bars of MA 6000 have been extruded at a ratio 2·75:1 temperature 1100°C, subjected to zone recrystallisation treatment in calibrated gradient furnace, and the (secondary) interface studied. By selected area channelling, 〈110〉 texture has identified, which is attributed ability tilt boundaries form low energy interfaces close packed nature. A curved secondary observed this shown result indirectly from strain gradients during extrusion. microbeam electron diffraction technique enabled...
The catalytic formation of hydroxyl radicals in oxidative hair colourant systems the presence added copper ions was measured and quantified using a colorimetric probe N,N'-(5-nitro-1,3-phenylene)bisglutaramide. Also monitored same experiments decomposition hydrogen peroxide. first set performed aqueous model solutions containing key oxidant actives colourant, ammonium hydroxide peroxide at pH 10, with calcium ions. second different levels conditions very close to those found during...
Globally, billions of individuals wash their hair in water, which acts as an exogenous metal source. Many studies measure the levels found on human specifically aim to remove materials prior analysis. Although this is needed when using analysis probe impact local environment endogenous levels, it not relevant for understanding exactly what a result contact with its daily environment. Understanding these are important, presence redox active metals, such copper and iron, can fibre health,...
To study the effects of addition a redox metal, copper, antioxidants and metal chelators on formation free radicals in natural white Caucasian hair subsequently exposed to UV light. Three different methods, electron paramagnetic resonance (EPR), fluorescent probe for hydroxyl radical (terephthalate) photoyellowing, were used. These methods utilized sources reaction conditions, so can give insights into mechanisms action occurring during oxidation hair. In addition, this demonstrates how be...
Scalp hair is among the most exposed parts of human body, yet impact visible and UV light on lipids, an important structural component hair, poorly researched. We have used lipidomics, a broad-based approach to measure lipids in samples, which has hitherto not been applied UV-exposed published literature, could allow for wider understanding how impacts specific lipids.Mixed blonde Caucasian switches were divided into two groups five, with half mimicking normal daytime exposure left...
