Differential binding of piperine & curcumin with modified cellulose, alginate and pectin supports: In-vitro & in-silico studies. Int J Biol Macromol 2023; 233:123508. [PMID: 36739052 DOI: 10.1016/j.ijbiomac.2023.123508] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2022] [Revised: 01/20/2023] [Accepted: 01/29/2023] [Indexed: 02/05/2023]
Abstract
Use of natural polymer in the development of Drug Delivery Systems (DDS) has greatly increased in recent past because of their biocompatible, non-allergic and biodegradable nature. Natural polymers are usually hydrophilic supports, so in order to be a carrier of a hydrophobic drug their nature needs to be changed. Each developed system behaves differently towards different drugs in terms of loading and sustained release of the drug as well. In the present work we report differential binding of piperine & curcumin with cetyltrimethylammonium bromide (CTAB) modified cellulose, alginate and pectin. Difference in interaction between the piperine and curcumin with supports has been visualized using in-vitro as well as in-silico studies. Initial results obtained after in-silico studies have been validated via time dependent anti-trypsin, serum protein binding, anti-cathepsin, anti-oxidant, and anti-α-amylase activities. FT-IR, SEM, fluorescence and Particle size have been used to characterize the piperine loaded on CTAB-modified polymeric supports.

Abstract
Kaempferol and Myricetin alone have promising benefits on diabetes and related complications, yet the effectiveness of cotreating the two compounds on diabetes have not been studied. The existing investigation was to study the combined anti-diabetic effect of kaempferol and myricetin in Streptozotocin (STZ)-activated diabetes in rats. To evaluate the anti-diabetic activity, 36 Wistar rats were segregated into six groups; Normal, 50 mg/kg STZ-induced diabetes, and four (50 mg/kg kaempferol, 50 mg/kg myricetin, 25 mg/kg kaempferol + myricetin, and 5 mg/kg glibenclamide) compound-treated diabetic groups. The effects of co-treatment on parameters, glucose, insulin, lipid profile, liver enzymes, antioxidant biomarkers, and inflammatory cytokines were measured. The study revealed that combined treatment restored the assessed parameters including glucose levels, inflammatory cytokines, oxidative markers, and lipid and liver enzymes in diabetic rats. The results indicate that cotreatment of kaempferol and myricetin has a beneficial role against diabetes suggesting that cotreatment of these compounds can be used therapeutically in treating diabetes.

Abstract
Despite vaccines are the main strategy to control the ongoing global COVID-19 pandemic, their effectiveness could not be enough for individuals with immunosuppression. In these cases, as well as in patients with moderate/severe COVID-19, passive immunization with anti-SARS-CoV-2 immunoglobulins could be a therapeutic alternative. We used caprylic acid precipitation to prepare a pilot-scale batch of anti-SARS-CoV-2 intravenous immunoglobulins (IVIg) from plasma of donors immunized with the BNT162b2 (Pfizer-BioNTech) anti-COVID-19 vaccine (VP-IVIg) and compared their in vitro efficacy and safety with those of a similar formulation produced from plasma of COVID-19 convalescent donors (CP-IVIg). Both formulations showed immunological, physicochemical, biochemical, and microbiological characteristics that meet the specifications of IVIg formulations. Moreover, the concentration of anti-RBD and ACE2-RBD neutralizing antibodies was higher in VP-IVIg than in CP-IVIg. In concordance, plaque reduction neutralization tests showed inhibitory concentrations of 0.03-0.09 g/L in VP-IVIg and of 0.06-0.13 in CP-IVIg. Thus, VP-IVIg has in vitro efficacy and safety profiles that justify their evaluation as therapeutic alternative for clinical cases of COVID-19. Precipitation with caprylic acid could be a simple, feasible, and affordable alternative to produce formulations of anti-SARS-CoV-2 IVIg to be used therapeutically or prophylactically to confront the COVID-19 pandemic in middle and low-income countries.

J Food Sci 2021; 86:5318-5328. [PMID: 34796506 DOI: 10.1111/1750-3841.15965] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2021] [Revised: 09/28/2021] [Accepted: 10/11/2021] [Indexed: 11/29/2022]
Abstract
Fish myofibrillar protein is underutilized due to the formation of insoluble aggregates in low salt media. High pressure homogenization (HPH) at 20, 40, and 60 MPa for four passes was applied on bighead carp myofibrillar protein in order to modify its structure and interfacial properties. Changes in aggregation, conformation, solubility, emulsifying and foaming properties of myofibrillar protein were investigated. The aggregates of myofibrillar protein were obviously disrupted by HPH treatment. The size of myofibrillar protein aggregates became smaller and more uniform as the treating pressure increased, accompanied by notable decreases of cross-sectional height and Rq value in AFM image. Furthermore, the conformation of HPH-treated myofibrillar protein was unfolded into a flexible and open structure. α-helix and β-sheet were converted into β-turn and random coil. Surface hydrophobicity and zeta potential were strengthened, along with the exposure of sulfhydryl groups onto molecule surface. On the other hand, solubility, emulsifying activity index (EAI) and foaming capacity (FC) of HPH-treated myofibrillar protein were markedly enhanced with the increasing pressure. Especially after HPH treatment at 60 MPa, myofibrillar protein was almost dissolved in low salt media (solubility 91.86%) with 4.92 fold for EAI and 3.52 fold for FC. But there was little variation in emulsifying and foaming stabilities. These results suggested that HPH treatment has interesting potential to induce the dissociation and unfolding of myofibrillar protein in low salt media, therefore improving its interfacial properties. PRACTICAL APPLICATION: Carp myofibrillar protein was treated by high pressure homogenization (HPH). Aggregates of myofibrillar protein were disrupted into smaller size form. Conformation of myofibrillar protein was unfolded into open and loose structure. Emulsifying and foaming capacities of myofibrillar protein were improved. HPH treatment modified the structure and interfacial properties of myofibrillar protein.

Abstract
In the current global emergency due to SARS-CoV-2 outbreak, passive immunotherapy emerges as a promising treatment for COVID-19. Among animal-derived products, equine formulations are still the cornerstone therapy for treating envenomations due to animal bites and stings. Therefore, drawing upon decades of experience in manufacturing snake antivenom, we developed and preclinically evaluated two anti-SARS-CoV-2 polyclonal equine formulations as potential alternative therapy for COVID-19. We immunized two groups of horses with either S1 (anti-S1) or a mixture of S1, N, and SEM mosaic (anti-Mix) viral recombinant proteins. Horses reached a maximum anti-viral antibody level at 7 weeks following priming, and showed no major adverse acute or chronic clinical alterations. Two whole-IgG formulations were prepared via hyperimmune plasma precipitation with caprylic acid and then formulated for parenteral use. Both preparations had similar physicochemical and microbiological quality and showed ELISA immunoreactivity towards S1 protein and the receptor binding domain (RBD). The anti-Mix formulation also presented immunoreactivity against N protein. Due to high anti-S1 and anti-RBD antibody content, final products exhibited high in vitro neutralizing capacity of SARS-CoV-2 infection, 80 times higher than a pool of human convalescent plasma. Pre-clinical quality profiles were similar among both products, but clinical efficacy and safety must be tested in clinical trials. The technological strategy we describe here can be adapted by other producers, particularly in low- and middle-income countries.

Abstract
AIM To evaluate the sex-specific effects of a hydroalcoholic extract from Eugenia punicifolia (HEEP) leaves on gastric ulcer healing.
METHODS In this rat study involving males, intact (cycling) females, and ovariectomized females, gastric ulcers were induced using acetic acid. A vehicle, lansoprazole, or HEEP was administered for 14 d after ulcer induction. Body weight was monitored throughout the treatment period. At the end of treatment, the rats were euthanized and the following in vivo and in vitro investigations were performed: macroscopic examination of the lesion area and organ weights, biochemical analysis, zymography, and evaluation of protein expression levels. Additionally, the concentration-dependent effect of HEEP was evaluated in terms of subacute toxicity and cytotoxicity.
RESULTS Compared to the vehicle, HEEP demonstrated a great healing capacity by substantially reducing the ulcerative lesion area in males (52.44%), intact females (85.22%), and ovariectomized females (65.47%), confirming that HEEP accelerates the healing of acetic acid-induced gastric lesions and suggesting that this effect is modulated by female sex hormones. The antiulcer effect of HEEP was mediated by prostaglandin E2 only in male rats. Overall, the beneficial effect of HEEP was the highest in intact females. Notably, HEEP promoted the expression of vascular endothelial growth factor (intact vs ovariectomized females) and decreased the expression of Caspase-8 and Bcl-2 (intact female vs male or ovariectomized female). Additionally, HEEP enhanced fibroblast proliferation and migration into a wounded area in vitro, confirming its healing effect. Finally, no sign of subacute toxicity or cytotoxicity of HEEP was observed.
CONCLUSION In gastric ulcers, HEEP-induced healing (modulated by female sex hormones; in males, mediated by prostaglandin) involves extracellular matrix remodeling, with gastric mucosa cell proliferation and migration.

[PMID: 27720977 DOI: 10.1016/j.toxicon.2016.10.007] [Citation(s) in RCA: 27] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2016] [Revised: 08/26/2016] [Accepted: 10/05/2016] [Indexed: 11/22/2022]
Abstract
A new whole IgG, freeze-dried, polyspecific antivenom was prepared from the plasma of horses immunized with the venoms of the snakes Daboia russelii, Echis carinatus, Hypnale hypnale, and Naja naja from Sri Lanka. The preclinical neutralizing ability of this antivenom against several toxic and enzymatic activities of these four venoms was analyzed, and compared with that of a batch of VINS antivenom (India) being currently used in Sri Lanka. The activities tested were: lethality, hemorrhagic, in vitro coagulant, proteinase and phospholipase A2. Both antivenoms neutralized, to a different extent, these activities of the venom of D. russelii, E. carinatus, and N. naja. In general, the polyspecific Sri Lankan antivenom was more effective than the Indian antivenom in the neutralization of the venoms of D. russelii and E. carinatus, whereas the Indian antivenom showed a higher efficacy against the venom of N. naja. Regarding H. hypnale, the new Sri Lankan antivenom was effective in the neutralization of all activities tested, whereas the Indian antivenom neutralized lethality but not hemorrhagic, coagulant, proteinase and PLA2 activities, in agreement with the fact that this venom is not included in the immunization mixture for this antivenom. Results suggest that the new polyspecific Sri Lankan antivenom has a satisfactory preclinical neutralizing profile and compares favorably with the Indian antivenom. This is ready to be tested in a clinical trial to evaluate its efficacy and safety in human victims of snakebite envenomings by D. russelii, E. carinatus and H. hypnale in Sri Lanka.

Abstract
Background Tobacco smoking by pregnant women has a negative effect on fetal development and increases pregnancy risk by changing the oxidative balance and microelements level. Smoking affects the concentration, structure and function of proteins, potentially leading to various negative effects on pregnancy outcomes. Methodology/Principal Findings The influence of tobacco smoke on key protein fractions in smoking and non-smoking healthy pregnant women was determined by capillary electrophoresis (CE). Concentrations of the proteins α1-antitrypsin, α1-acid glycoprotein, α2-macroglobulin and transferrin were determined by ELISA tests. Total protein concentration was measured by the Biuret method. Smoking status was established by cotinine levels. Cadmium (Cd) and Zinc (Zn) concentrations were determined by flame atomic absorption spectrometry and the Zn/Cd ratio was calculated based on these numbers. Smoking women had a 3.7 times higher level of Cd than non-smoking women. Zn levels decreased during pregnancy for all women. The Zn/Cd ratio was three times lower in smoking women. The differences between the changes in the protein profile for smoking and non-smoking women were noted. Regarding proteins, α1-antitrypsin and α2-macroglobulin levels were lower in the non-smoking group than in the smoking group and correlated with Cd levels (r = -0.968, p = 0.032 for non-smokers; r = −0.835, p = 0.019 for smokers). Zn/Cd ratios correlated negatively with α1-, α2- and β-globulins. Conclusions/Significance Exposure to tobacco smoke increases the concentration of Cd in the blood of pregnant women and may lead to an elevated risk of pregnancy disorders. During pregnancy alter concentrations of some proteins. The correlation of Cd with proteins suggests that it is one of the causes of protein aberrations.

Preclinical evaluation of three polyspecific antivenoms against the venom of Echis ocellatus: Neutralization of toxic activities and antivenomics. Toxicon 2016; 119:280-8. [PMID: 27377229 DOI: 10.1016/j.toxicon.2016.06.022] [Citation(s) in RCA: 27] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2016] [Revised: 06/23/2016] [Accepted: 06/30/2016] [Indexed: 01/26/2023]
Abstract
Snakebite envenoming has a heavy burden in the public health in sub-Saharan Africa. The viperid species Echis ocellatus (carpet viper or saw-scaled viper) is the medically most important snake in the savannahs of western sub-Saharan Africa. Several antivenoms are being distributed and used in this region for the treatment of envenomings by E. ocellatus, but the preclinical efficacy of some of these antivenoms has not been assessed. The present study evaluated the preclinical efficacy against E. ocellatus venom of three polyspecific antivenoms: (a) Snake Venom Antiserum (Pan Africa), manufactured by Premium Serums and Vaccines (India); (b) Snake Venom Antiserum (Africa), manufactured by VINS Bioproducts (India); and (c) Antivipmyn(®) Africa, manufactured by Instituto Bioclon (Mexico). Antivenomics analysis revealed the ability of the three antivenoms to immunocapture the majority of components of the venoms of E. ocellatus from Cameroon, Nigeria and Mali, although their maximal immunocapturing capability varied. Bioclon and Premium Serums antivenoms were effective in the neutralization of lethal, hemorrhagic and in vitro coagulant activities of the venom of E. ocellatus from Cameroon, albeit with different potencies. VINS antivenom neutralized hemorrhagic activity of this venom, but failed to neutralize lethality at the highest antivenom dose tested, and had a low neutralizing efficacy against in vitro coagulant effect.

Abstract
BACKGROUND Human immunodeficiency virus (HIV) and Hepatitis B virus (HBV) share similar routes of transmission, making it possible for an individual to have a co-infection. HBV infection is well known to be a major cause of chronic liver diseases worldwide. The aim of this study was to determine the prevalence of HBV infection among HIV infected HAART naïve patients and investigate the effect of co-infection on CD4 count and liver function. STUDY DESIGN This was a hospital based descriptive cross sectional study of one hundred consecutive therapy-naive HIV-infected individuals. The CD4 count, Hepatitis B surface antigen, Serum albumin, total Protein, and liver enzymes were determined using standard techniques. RESULTS The prevalence of HIV and HBV co-infection was 37%. The mean serum ALT and ALP were significantly higher in the co- infected patients (P-values <0.05). The mean CD4 count of the mono infected patients was significantly higher (p-value of 0.014). The mean serum ALT, AST and ALP of mono and co-infected patients with CD4 count<200/µl were significantly higher than those with count ≥ 200 cells/µl. (p-value of <0.01). The mean ALT and AST of the co-infected patients and all patients with CD4 count <200 cells/µl were higher than the normal reference range. CONCLUSION Approximately one third of HIV positive patients had hepatitis B virus co-infection. Co-infection and CD4 count <200 cells/µl are likely to result in abnormal ALT and AST. We recommend that co-infected patients and those with CD4 count <200 cells/µl should be given non-hepatotoxic antiretroviral drug.

Abstract
The potential impact of protein oxidation on the functional properties of myofibrillar proteins (MP) was investigated in the present study. To accomplish this purpose, myofibrillar proteins were oxidized in vitro for 12 days at 37 °C in the presence of Cu(2+), Fe(3+), and Mb in combination with H(2)O(2) and analyzed at sampling times for chemical changes induced by oxidative reactions and functional properties. The oxidation measurements included specific protein carbonyls (α-aminoadipic semialdehyde, AAS), advanced lysine oxidation products (α-aminoadipic acid, AAA, and Schiff bases), and thiobarbituric acid-reactive substances (TBARS). The factors and mechanisms involved in the oxidative degradation of lysine residues through the carbonylation pathway are precisely described. According to the present results, intense lipid and protein carbonylation, principally induced by Cu(2+)/systems, leads to a fast and severe loss of MP functionality, including impaired water-holding, foaming, and gelling capacities. The implication of Mb in the oxidation events enhances the production of AAA and Schiff bases, compromising to a larger extent the solubility of MP and worsening the aggregation and the gelling capacity. The connection between the oxidation-induced chemical changes and the loss of protein functionality is thoroughly discussed.

Abstract
The current shortages in human plasma products at global levels justify the development of new, cost effective plasma fractionation methods. We have developed a fractionation process to obtain immunoglobulin G (IgG) and albumin-enriched fractions based on polymer-salt aqueous two phase system (ATPS). A small-scale (0.02 L) ATPS composed of polyethyleneglycol 3350 (PEG), potassium phosphate and sodium chloride, at pH 6.1, was evaluated and subjected to 50-fold scale-up (1 L). Further purification of the fractions was performed using caprylic acid precipitation and ion exchange chromatography. Similar yield and purity were obtained at both small and large scales. IgG precipitated in the PEG rich upper phase at 83% recovery and 2.75-fold purification factor. An 81% pure albumin fraction was obtained in the salt rich bottom phase with a 91% yield. After polishing, IgG was obtained at a recovery of 70% and a purity of 92%. Corresponding values for albumin were 91% and 90%. This IgG and albumin fractionation technology deserves further evaluation as it may represent a potential alternative to conventional plasma fractionation methods.

Abstract
This study was conducted to prepare basic materials and offer advice regarding dietary habits to prevent and cure childhood obesity by comparing and analyzing dietary habit, nutritional status, blood factors, and mineral contents of hair. All subjects were stratified by their weight-length index (WLI). According to the standard WLI values, 64.9% of children were within the normal value, 13.5% of children were underweight, and 21.6% of children were overweight and obese (WLI ≥ 110%). Overall, the score assessed dietary habit for all children was 21.32 ± 2.55 point (921 subjects), with 5.1% of children having excellent dietary habits and 3.1% having poor dietary habits. Additionally, 37.9% of underweight children, 37.6% of normal weight children, and 43.2% of overweight and obese children consumed higher amounts of protein than underweight children did (meat, fish, eggs, and soy products) (P < 0.05). Overweight and obese children consumed more fried foods than underweight or normal weight children (P < 0.05). Moreover, 38.0% of the children had hemoglobin levels of 12 g/dl, while 7.6% were anemic (11.1 g/dl). When a hematocrit level of 33% was taken as the standard, 11.0% of children were anemic. The plasma transferrin content was 263.76 ± 54.52 mg/dl in overweight and obese children. The mean values of Fe, Cu, Ca, Cr, Mn, Se, Na, K, Li, V, Co, and Mo were within the reference values, but the Zn concentrations of underweight, normal weight, and overweight and obese children were 67.97 ± 28.51 ppm, 70.09 ± 30.81 ppm, and 73.99 ± 30.36 ppm, respectively. The Zn concentration of overweight and obese children (73.99 ± 30.36 ppm) was lower than that of the standard value (180~220 ppm). Therefore, a nutritional education program and new guidance for dietary pattern should be developed to reduce the number of underweight and overweight and obese children.

Abstract
We examined the changes induced by daily treadmill exercise on body weights, plantaris muscle weights, plantaris protein concentrations, and L-leucine-4,5-3H incorporation into plantaris muscles of normal and castrated young male guinea pigs and of castrated animals receiving testosterone replacement therapy, and compared the testosterone-1,2-3H uptake by plantaris muscles of trained normal guinea pigs to that of untrained animals. Trained animals exhibited significantly lower body and muscle weights and greater labeled leucine incorporation into sarcoplasmic and myofibrillar proteins but did not show significant changes in protein concentrations or labeled testosterone uptake. The level of physical activity of the young animals studied appeared to be more important than gonadal endocrine function in altering protein metabolism and muscle and body weights. Because hypertrophy did not occur in the trained plantaris muscles, which had elevated rates of labeled leucine incorporation, it appears that the trained animals had a higher muscle protein turnover rate. It seems unlikely that testosterone plays an important role in these activity-related phenomena.

Abstract
The male reproductive tract of
Octopus dofleini martini
lies enclosed in the genital bag, inside the mantle cavity. It consists of the testis, vas deferens proximale, spermatophoric gland system I (seminal vesicle), spermatophoric gland system II (prostate), vas deferens distale, spermatophoric sac (Needham’s sac) and the terminal spermatophoric duct. The spermatozoa, which upon leaving the testis are as yet not encased, pass first into the vas deferens proximale, which in its gross appearance resembles the epididymis; they then traverse the two tubular spermatophoric gland systems I and II, where they become encased into the spermatophores. Subsequently the spermatophores pass through the vas deferens distale into the spindle-shaped spermatophoric sac, and from there they enter singly the terminal spermatophoric duct consisting of the diverticulum and terminal organ or ‘penis’. The slender cylindrical body of the spermatophore is about 1 m long and consists of two parts, approximately equal in length. The thicker ‘proximal’ ‘male-oriented’ portion, which emerges first from the orifice of the ‘penis’, contains the tightly coiled sperm rope suspended in a viscous and transparent fluid, the spermatophoric plasma; the thinner ‘distal’ ‘femaleoriented’ half of the spermatophore is taken up by the rod-shaped, hyaline core of the ejaculatory apparatus. In between is located the cement body, and the amber-coloured cement liquid. At the distal end of the spermatophore the outer coating forms a cap and a filamentous appendage, the cap-thread. Chemical analyses were performed on spermatozoa, spermatophoric plasma, cement liquid, outer tunic and the hyaline core of the ejaculatory apparatus, obtained from freshly recovered spermatophores. Glycogen was identified as a major constituent of spermatozoa. The extraordinarily high dry-weight content of spermatophoric plasma (nearly 30%) was shown to be largely due to bound amino sugar, carbohydrate, peptide and protein. A peptide separated from the spermatophoric plasma by ultrafiltration was found to be made up to a great extent of aspartic acid and serine. The outer tunic, a tough and elastic membrane, which envelops the body of the spermatophore, was shown to consist mostly of a protein which is rich in proline, lysine, aspartic acid and threonine. The mechanics of the spermatophoric reaction
in vitro
have been studied in spermatophores extracted manually from the male octopus and placed in sea-water. The complete spermatophoric reaction under such conditions lasted 1 to 2 h. During that interval the sperm rope gradually advanced a distance of about 1 m, from the proximal towards the distal end of the spermatophore. The terminal phase of this process involved an evagination of the ejaculatory apparatus, followed by a rapid movement of the sperm rope; as the sperm rope entered the end portion of the spermatophore, the latter ballooned out into an egg-shaped bladder. Among the factors which contribute to the formation of the spermatophoric bladder, the most important ones are (i) the elasticity of the membranes of the spermatophore, (ii) the extrusion, and subsequently evagination, of the ejaculatory apparatus, and (iii) the influx of sea-water into the spermatophore’s body which causes an approximately fivefold increase in the volume of spermatophoric plasma. Concomitantly with the uptake of sea-water, the dry weight of the spermatophorie plasma declines but the sodium chloride concentration increases. However, the osmolality of the spermatophoric plasma, as assessed by freezingpomt depression, is not altered during the spermatophoric reaction. Events at copulation, that is under conditions
in vivo
, closely resembled those observed in spermatophores undergoing a spermatophoric reaction
in vitro
. An interval of 2 to 3 h usually elapsed from the time when the male, using his hectocotylized arm, mserted mto the female the distal (female-oriented) end of a spermatophore, to the moment of the male's withdrawal. After accomplished copulation two spermatophores were usually found firmly lodged in the two oviducts. The sperm-free remnants of the spermatophore bodies dangled free from the orifices of the oviducts. Upon dissection of recently mated females the spermatophoric bladder was usually found within the oviduct, held firmly in position by the evaginated ejaculatory apparatus.
