Randomized controlled trial of trehalose An efficient autophagic bioprotectant in the management of dry eye disease Morya AK, Solanki K, Prakash S, Samota M, Gupta A, - Taiwan J Ophthalmol
PURPOSE: To compare the therapeutic effect of sodium hyaluronate (SH)–trehalose (Trehalube, Microlabs, Bangalore, India, SH 0.1% and trehalose 3%) or SH (0.1% Hylotears, Raymed, Chandigarh, India) alone in patients with dry eye disease (DED).MATERIALS AND METHODS: Patients were randomized into two groups: SH-trehalose (SH 0.1% and trehalose 3%) or SH (0.1% Hylotears) alone. The Ocular Surface Disease Index (OSDI) questionnaire was used to assess patient's symptoms. Patients were followed up at 4 and 8 weeks, and OSDI score, tear film break-up time (TBUT), tear film height (TFH), Schirmer's test, and conjunctival staining were evaluated at each visit.RESULTS: A total of 384 patients were included in the study, 192 patients in each arm. The mean age of participants was 37.62 + 14.4 years and 225 were women (56%). The improvement in Schirmer's test was significantly better in the SH-trehalose group at 8 weeks (5.26 + 4.3 mm, 95% confidence interval = 4.6–5.9 mm) compared to the SH group (3.71 + 3.9, 95% confidence interval = 3.15–4.28 mm). The TBUT and TFH showed slight improvement at 4 weeks in both groups, but not at 8 weeks. There were no group differences at all-time points in terms of conjunctival staining and OSDI-based grades of DED.CONCLUSION: It was found that treating dry eye with SH-trehalose leads to greater improvement in the Schirmer's values and TBUT after 8 weeks of sustained use in patients with DED, and this was more pronounced in those with severe DED.

The Glycocalyx Explained A Protective Gel Lining of the Capillaries - YouTube
The Glycocalyx Explained A Protective Gel Lining of the Capillaries - YouTube
Could you have imagined that one of the most essential elements for your good health lies in a vast protective gel lining of all of your capillaries that touches each of your trillions of cells … and most likely, you’ve never even heard about it. Come with me as we travel inside your vascular system and flow along with your blood. Every cell of your body is nourished by the blood that travels through the capillaries that make up 99% of your circulatory system-from head to toe. Placed end-to-end, scientists estimate they would extend 60,000 miles, enough to go around the earth two and a half times. With every heartbeat, vital nutrients and oxygen are delivered and waste is removed from each cell. This essential process breaks down with aging, poor diet, lack of exercise, genetics, stress and smoking. New medical science has revealed the importance of a transparent micro-thin gel-like lining in your blood vessels that protects your entire circulatory system. In the past, blood vessels were thought to be simple hollow tubes. But with today’s high resolution video microscopes, a discovery reveals that the entire circulatory system is coated with a gel like lining that protects the inside walls of the arteries, veins and capillaries. This protective gel-like lining of the capillaries and all other blood vessels is called the glycocalyx. Its integrity is essential to the healthy function of all the cells, organs and body systems. The glycocalyx keeps your body healthy in three critical ways. First, it functions as the natural trigger that stimulates the production of nitric oxide. Nitric oxide is vital in controlling blood flow and blood pressure. The glycocalyx stores anti-oxidants and, working together with nitric oxide, both increase blood flow, on demand, when organs call for it. For example, when you’re walking upstairs. Or even when your brain is working through a difficult problem. Bottom line: your body needs a thick and healthy glycocalyx to efficiently regulate blood flow. Second, a healthy glycocalyx allows your body to engage more of the available capillaries of the microvascular system when blood flow increases. This is critical to regulate the supply of nutrients and oxygen, and the removal of waste and carbon dioxide, according to the body’s level of activity, such as when you exercise. Bottom line: While blood flow control is important, the glycocalyx allows your body to engage more capillaries when organs demand nourishment and waste removal. Third, capillaries are much more than simple hollow tubes. In fact, their inner surface is coated with the non-stick glycocalyx that prevents loss of capillaries through fluid leakage, blood clotting and inflammation. This coating prevents sticking when you don’t need it, and it keeps blood clotting and inflammation under control. For example, when your body’s healthy, it can repair a simple cut or fight an infection. Bottom line: a healthy glycocalyx not only engages more capillaries when blood flow goes up, but it also protects the capillary network and even the entire vascular system from deterioration and loss. Ongoing clinical research from more than 50 studies confirms that a compromised glycocalyx and a damaged microvascular system are linked to organ starvation. Early warning signs of organ starvation include cold hands and feet, leg cramps, skin problems, hair thinning, fatigue, lack of focus, memory loss, certain eye problems, hearing loss, severe PMS, erectile dysfunction, high blood pressure, and even type 2 diabetes. Emerging research is beginning to show that it’s not too late to slow down, or even reverse, the breakdown of the protective properties of the glycocalyx. More at https://microvascular.com/

Agriculture Free Full-Text Monitoring of Pesticides in the Cultivation of Nopal Vegetable (Opuntia ficus-indica (L.)) Mill, Morelos, México
The presence of pesticide residues in vegetable and fruit products, as a consequence of inappropriate application in some cases, constitutes a risk to the health of the exposed population. In Mexico, the official norm, NOM-003-STPS-1999, only allows the use of pesticides with the phytosanitary registry, the responsible state commission for the control of the process and use of pesticides and toxic substances, which recommends doses and permitted crops. Despite the above, it is still common to find pesticide residues in some vegetable products. In this study, the following were detected: Chlorpyriphos, Dimetomorph I, Malathion, Omethoate, Carbendazim, and Imidacloprid in Nopal. The study was carried out in two collection centers located in the state of Morelos. In total, sixty samples were taken, thirty for each collection center, for a period of 10 months. To determine the pesticide residues, the analytical methodology was used, according to the guide, SANTE/11945/2015; in a laboratory accredited by the Mexican Accreditation Entity A. C. in the norm, NMX-EC-17025-IMNC-2006. The procedure for extracting analytes was carried out using the method, QuEChERS. The highest concentration of the pesticides detected in the samples obtained from the non-Certified Supply Center were Chlorpyrifos 0.309 mg/kg (MRL 0.01), Dimetomorf I 0.029 mg/kg (MRL 0.01), Malathion 0.155 mg/kg (MRL 0.01), Omethoate 0.032 (MRL 0.01), Carbendazim 0.090 mg/kg (MRL 0.01), and Imidacloprid 0.058 mg/kg (MRL 0.01). Thirty percent of the samples analyzed showed pesticide residues; the most frequent were Carbendazim. The results for the estimated daily intake (EDI) oscillated between 6.5 × 10−5 and 1.3 × 10−4 mg/kg body weight for the vegetable, Nopal. In principle, it could be concluded that the consumption of Nopal with pesticide residues does not represent any toxicological risk for human health, however, the risk cannot be ruled out due to the intake of other vegetables and fruits that are cultivated in the Mexican Republic, which probably present pesticide residues, which together would raise potential risks to human health.

Effect of Nopal ( Opuntia ficus indica) Consumption at Different Maturity Stages as an Only Calcium Source on Bone Mineral Metabolism in Growing Rats SpringerLink
This work determines the effect nopal consumption at different maturity stages (60, 200, 400, and 600 g) as the only calcium source in bone metabolism. The apparent mineral absorption, the biomarkers of bone metabolism, the bone mineral density at different femoral regions, and crystal properties of the bone were evaluated during the growth stage. The Ca absorption was increased with the rat age in most of the experimental groups, while Mg supplementation decreased intestinal absorption probably due to a saturation process. Intestinal Ca and Mg absorption showed an opposite trend; this result suggests that both ions can compete for vitamin D absorption sites. The percentage of absorption of K was lower in the groups fed with Nopal; nevertheless, due to supplementation, the net absorption was higher than the control group. In all groups, osteocalcin levels decreased with the rat age. Nopal consumption increased osteocalcin levels during the adolescence stage in comparison to the control group. Amino N-terminal propeptide of type I procollagen levels increased in puberty and adolescence in all groups compared to the control group. Bone mineral density in different femoral regions was lower in the groups fed with nopal at early maturity stages (N-60 and N-200) than the groups fed with nopal at late maturity stages (N-400 and N-600). The crystal size of hydroxyapatite exhibited changes for all the groups, indicating the inclusion of mono and divalent ions in calcium replacement. On this basis, the nopal at late maturity stage contributed to bone formation.

Disaccharide glasses are increasingly used to immobilize proteins at room temperature for structural/functional studies and long-term preservation. To unravel the molecular basis of protein immobilization, we studied the effect of sugar/protein concentration ratios in trehalose or sucrose matrixes, in which the bacterial photosynthetic reaction center (RC) was embedded as a model protein. The structural, dynamical, and H-bonding characteristics of the sugar–protein systems were probed by high-field W-band EPR of a matrix-dissolved nitroxide radical. We discovered that RC immobilization and thermal stabilization, being independent of the protein concentration in trehalose, occur in sucrose only at sufficiently low sugar/protein ratios. EPR reveals that only under such conditions does sucrose form a microscopically homogeneous matrix that immobilizes, via H-bonds, the nitroxide probe. We conclude that the protein immobilization capability depends critically on the propensity of the glass-forming sugar to create intermolecular H-bond networks, thus establishing long-range, homogeneous connectivity within the matrix.

Soluble and insoluble fractions from nopal (Opuntia ficus) cladodes improve postprandial glycaemic regulation a crossover randomized study in healthy volunteers
Background and objectives: Type 2 diabetes has been increasing all over the world. A healthy diet, including particular functional foods is an effective strategy to prevent this form of diabetes. Nopal (Oputia ficus) is a cactus plant that, according to traditional medicine, has antidiabetic properties. The objective of this research was to examine the effects of different fractions of nopal cladodes on postprandial glycaemic regulation in healthy volunteers. Methods: Nopal cladodes flour was separated by centrifugation into two fractions (a water insoluble and a soluble fraction). The fractions were incorporated into two different test breads, i.e. insoluble fraction bread (INB) and soluble fraction bread (SNB), and evaluated with respect to acute glycaemic properties in 17 healthy subjects with normal body mass index, applying a randomized cross-over study design. The effects on glycaemic and insulinaemic responses were compared with the responses after a control product, which composed of a similar bread lacking the nopal fractions (white wheat bread, WWB). The products were characterized with respect to starch and dietary fibre content. In addition, starch hydrolysis index (HI) was determined with an in-vitro method in order to predict glycaemic index (pGI),and elucidate possibly underlying mechanisms on postprandial glycaemia. Results: Results regarding glycaemic regulation show that insoluble nopal fractions had a beneficial effect on postprandial glucose regulation. Consequently, the incremental area under the postprandial blood glucose curve (iAUC) after INB was significantly reduced compared to after intake of the WWB during the time periods 0 – 45 and 0 – 60 minutes (p < 0.05). In addition, the iPeak value, i.e. the individual highest incremental peak concentrations, was significantly lowered after INB compared to WWB (P < 0.05). Regarding the postprandial insulin secretion, both SNB and INB lowered the postprandial iAUC compared to the WWB during the time period 0 – 45 and 0 – 60 minutes (P < 0.05). On the other hand, only the INB significantly reduced the insulin iPeak value compared to WWB (P < 0.05). In terms of HI, INB had lower HI and pGI compared to WWB and SNB. Also, INB exhibited highest total, soluble and insoluble dietary fibre contents. Conclusion: The INB promoted lower postprandial glucose and insulin response, while SNB showed beneficial effects only on postprandial insulin secretion. The beneficial effects of nopal on glycaemic regulation might be to some extent explained by the dietary fibre content, especially the INB. However, with respect to the improved postprandial insulin economy observed after the SNB, additional mechanisms are probably involved.

Water Insoluble Fraction of Nopal (Opuntia ficus) Cladodes Beneficially Affects Postprandial Appetite-related Variables, while the Soluble Fraction Has No Effect
Introduction: The world has witnessed a global trend of increasing obesity, which is directly linked to non-communicable diseases, such as type 2 diabetes (T2D). The epidemic of obesity is largely associated with consumption of high calorie diets and low physical activity. Food choice and exercise have a big impact to prevent obesity and T2D making these diseases highly related to personal lifestyle. The diet is one of the most important modifiable lifestyle factors that may be used to prevent obesity. Nopal (Opuntia Ficus Indica) is a cactus plant that has its origin in Mexico and has been used as traditional medicine to prevent overweight and obesity. Since Nopal cladodes are rich in several bioactive compounds, it may be considered as a functional food. The objective of this study was to investigate the perceived effect of Nopal cladodes on appetite variables in healthy humans. Method: Two test-products with two different fractions of Nopal cladodes flour (soluble Nopal fraction bread (SNB) and insoluble Nopal fraction bread (INB)) and a control product (white wheat bread (WB)) were studied in healthy young volunteers (n=17). The subjective appetite variables (hunger, satiety and desire to eat) were measured repeatedly by using a Visual Analog Scale (VAS) during a time perspective of three hours post consumption. Results: The INB resulted in significantly improved response in appetite variables (p < 0.05) compared to the WB. After consumption of the INB, the feeling of hunger and desire to eat were reduced by 27% and 32% respectively, while the feeling of satiety was increased by 25% during the period between 15-180 min post consumption. Importantly, the INB test product also resulted in a significant reduction on hunger and desire to eat, and an increased feeling of satiety during the final hour (120-180 min), compared to the control WB. Conclusion: The results indicate that the insoluble fraction of Nopal flour may beneficially affect appetite variables in healthy young adults. The results thus suggest that Nopal may help to modulate food intake and therefore contribute to antidiabetic effects previously observed with this edible plant.

Development of pH sensitive alginategum tragacanth based hydrogels for oral insulin delivery - Journal of Agricultural and Food Chemistry (ACS Publications)
Insulin entrapped alginate-gum tragacanth (ALG-GT) hydrogels at different ALG replacement ratios (100, 75, 50, 25) were prepared through an ionotropic gelation method, followed by chitosan (CH) polyelectrolyte complexation. A mild gelation process without the use of harsh chemicals was proposed to improve insulin efficiency. Retention of almost the full amount of entrapped insulin in a simulated gastric environment and sustained insulin release in simulated intestinal buffer indicated the pH sensitivity of the gels. Insulin release from hydrogels with different formulations showed significant differences (p < 0.05). Time domain (TD) NMR relaxometry experiments also showed the differences for different formulations, and the presence of CH revealed that ALG-GT gel formulation could be used as an oral insulin carrier at optimum concentrations. The hydrogels formulated from biodegradable, biocompatible, and nontoxic natural polymers were seen as promising devices for potential oral insulin delivery.
