Effect of Addition of Probiotics to Standard Treatment on Neonatal Jaundice

Objective: To compare the mean change in the bilirubin levels with addition of probiotics to standard treatment for the management of neonatal jaundice. Methodology: The randomized controlled trial was undertaken at the Neonatal Intensive Care Unit of the Paediatrics Department, Federal Government Polyclinic (Post Graduate Medical Institute), Islamabad from 1st April to 30th September 2019.  Neonates with hyperbilirubinemia requiring phototherapy were randomly divided into two groups, each having 30 patients. Group A received probiotics along with phototherapy while group B received phototherapy alone. Primary outcome was serum total bilirubin, which was calculated on 0, 1 and 3 days of treatment. Duration of phototherapy and patient's outcome was also recorded. Data was analyzed statistically using SPSS v. 23. Results: The mean serum bilirubin level after 24 hours was 14.27 ± 4.35 mg/dl in combination group while 16.43 ± 4.36 mg/dl in phototherapy group (p > 0.05). After 48 hours, the mean serum bilirubin level was 12.37 ± 3.33 mg/dl in combination group while 14.09 ± 3.60 mg/dl in phototherapy group (p > 0.05). After 72 hours, the mean serum bilirubin level was 11.09 ± 2.87 mg/dl in combination group while 11.72 ± 2.96 mg/dl in phototherapy group (p > 0.05). The mean time required of blue light phototherapy was 43.47 ± 20.71 hours in combination group while 61.53 ±28.27 hours in phototherapy group (p < 0.05). All neonates were discharged. Conclusion: Addition of probiotics to standard treatment decreased the time required for the phototherapy in neonatal jaundice. However no statistically significant difference was seen in the bilirubin levels between the two groups

Isolation and characterization of antihypertensive peptides from soy bean protein

Proteins and peptides are the most diverse biomolecules found in nature and make our interest due to their wide applications in food and pharmaceutical industry. Angiotensin Converting Enzyme (ACE) plays a major role in controlling blood pressure. The inhibition of ACE with peptides is a main target in the regulation of hypertension. The objective of the present study was to investigate the therapeutic potential of soy bean. This was accomplished by isolation of ACE inhibitory peptides using response surface methodology (RSM) and characterization of these bioactive peptides by mass spectrometry. 31 hydrolyzed fractions were isolated and evaluated for their ACE inhibition potential. Hydrolyzed fraction having highest ACE inhibitory activity was characterized by liquid chromatography-mass spectrometry (LC-MS) technique. RSM results showed maximum ACE inhibition potential (64%) by hydrolyzate was obtained at 45 ºC temperature, pH 8.0, E/S 0.2 in 2 hours hydrolysis time. Results of LC-MS analysis revealed Ser-Gly, Ser-Pro, Met-Ala, His-Ala, Lys-Pro, Phe-Thr, Met-Leu, Pro-Arg, Ala-Pro-Val, Pro-Ala-Leu, Val-Met-Gly, Pro-Leu-Val, Pro-Pro-Gln, His-Arg-Gly, Ser-Phe-Val-Leu, Ala-Val-His-Try, Arg-Thr-Val-Arg, His-His-Tyr-Leu-Val, Asp-Gly-Ala-Cys-Ser-Ala-Asn and MetVal-Thr-Gly-Pro-Gly-Cys-His bioactive peptides in hydrolyzed fraction of soy bean. Our data provide evidence that response surface methodology is a good approach for isolation of antihypertensive bioactive peptides with more potent activity as nutraceuticals or pharmaceuticals. Therefore soy bean can be use for industrial production of pharmaceutical grade natural medicines for handling high blood pressure

Efficient optimization and mineralization of UV absorbers: A comparative investigation with Fenton and UV/H2O2

UV absorbers developed for finishing of textile materials play a significant role in protection against UV radiations but their discharge in wastewater during processing and laundry action also retain serious concern to living species due to their recalcitrant nature. The current study examined the mineralization and degradation of two vinylsulfone and nitrogen (N-) containing UV absorber compounds (1a, 2a) via two effective Fenton and UV/H2O2 oxidation. The results showed that both the Fenton and UV/H2O2 processes mineralized the synthesized UV absorbers effectively; however the mineralization process with Fenton oxidation was more effective than the UV/H2O2. The mineralization of synthesized UV absorbers was affected by process parameters (dosage of Fe2+ and H2O2 pH and reaction time). Under attained optimum conditions of Fenton oxidation, dose of Fe2+ (15 mg/L), H2O2 (500 mg/L), pH (3.0) and contact time (120 minutes), 75.43 and 77.54% of Chemical Oxygen Demand removal was achieved for 1a and 2a, respectively. Whereas, the optimum conditions of UV/H2O2 process were H2O2 (700 mg/L), pH(3.0) and irradiation time (200 minutes) that brought 54.33 and 57.65% COD removal in case of 1a and 2a, respectively. The results indicated that the Fenton oxidation can be successfully employed for the mineralization of triazine based UV absorbers

Synthesis, characterization, DPPH radical scavenging, urease enzyme inhibition, molecular docking simulation, and DFT analysis of imine derivatives of 4-formylpyridine with selective detection of Cu+2 Ions

This study aimed to prepare three imine derivatives (1, 2, and 3) via a condensation reaction of phenyl hydrazine, 2-hydrazino pyridine, and 4-methoxy aniline with 4-formyl pyridine. Electron impact mass spectrometry (EIMS), proton nuclear magnetic resonance (1H-NMR), ultraviolet-visible (UV-Vis) and Fourier transform infrared (FTIR) spectroscopy were utilized for the characterization. The chemosensing properties of [4((2-phenyl hydrazono)methyl) pyridine] (1), [2-(2-(pyridin-4-ylmethylene)hydrazinyl) pyridine] (2), and [4-methoxy-N-yl methylene) aniline] (3) imino bases have been explored for the first time in aqueous media. The photophysical properties of chemosensors (1, 2, and 3) were examined by various cations (Na+, NH4+, Ba+2, Ni+2, Ca+2, Hg+2, Cu+2, Mg+2, Mn+2, and Pd+2). The chemosensor (1) showed very selective binding capability with copper ions at low concentrations (20 μM) without the influence of any other mentioned ions. The maximum complexation was noted with Cu+2 and 1 at pH between 7 to 7.5. The stoichiometry binding ratio between chemosensor (1) and Cu+2 was determined by Job\u27s plot and it was found to be 1:2. The current study explored the use of these Schiff bases for the first time as heterocyclic chemosensors. DPPH radical scavenging, urease enzyme inhibition activities, molecular docking simulation, and density functional theory (DFT) analysis of compounds 1, 2, and 3 were also conducte

Epilepsy control with carbamazepine monotherapy from a genetic perspective

Abstract Background Ethnicity variation is one of the main factors that may affect drug response in clinical practice. As MTHFR gene affects different transcriptome and proteome which affect the clinical response of drugs. Purpose of the current study was to observe possible variations in plasma levels of carbamazepine monotherapy and seizures’ control in Pakhtun population of Khyber Pakhtunkhwa (KP) in the context of MTHFR (C677T and A1298C) gene polymorphisms. Methods Blood was collected from the epileptic patients treated with carbamazepine monotherapy for the first time following respective oral doses on its steady state concentration after 3 h of morning dose at 3rd and 6th month of the therapy. Plasma carbamazepine levels were determined using reverse phase high performance liquid chromatography after method validation. MTHFR (C677T, AA298C) gene was genotyped. Patients were followed on 3rd and 6th month of the therapy for monitoring of response to carbamazepine therapy. Results Following for 3rd and 6th month of duration of carbamazepine therapy, poor seizure controlled patients were more likely noticed in heterozygous variants (677CT and 1298 AC) of MTHFR gene (P  0.05) difference in the dose and plasma level of carbamazepine among different genotypes of MTHFR (C677T and A1298C) gene. Similarly, the difference in dose and plasma level of carbamazepine was not significant (P > 0.05) in the responder and non-responder people with epilepsy. Conclusion Our study suggests that heterozygous variants of MTHFR (C677T and A1298C) gene are associated with poor seizure control in Pakhtun population of KP despite the fact that plasma level of carbamazepine were found within the therapeutic range

Evaluation and optimization of nanosuspensions of Chrysanthemum coronarium and Azadirachta indica using Response Surface Methodology for pest management

The rapidly emerging field of nanotechnology is considered an important achievement in the agriculture sector to increase the pest mortality rate and improve the crop production. The present study evaluates the novel pesticidal and anti-microbial activities of Chrysanthemum coronarium and Azadirachta indica in the nano-suspensions form. The anti-solvent precipitation method was used to formulate nano-suspensions proposed by Response Surface Methodology (RSM). Physicochemical nature of plant extracts and nano-suspensions was characterized through analysis of Zeta-sizer, FT-IR, and HPLC. Characterization results revealed a minimum particle size of 121.1 and 170.1 nm for Chrysanthemum coronarium and Azadirachta indica, respectively. The pesticidal activity of nano-suspension was performed against red flour beetle (RFB) and lesser grain borer (LGB) pests, which showed the maximum mortality rate of 100% with 100% concentration of plant extracts and nano-suspensions of Chrysanthemum coronarium and Azadirachta indica against both insects. In comparison, the combination of these both plant extracts revealed the maximum 100% mortality with a 50% concentration of nano-suspensions (mixing ratio 1:1) after 72 h. The antibacterial activity showed the maximum zone inhibition of 9.96 +/- 0.17 and 14.17 +/- 0.50 mm against S. aureus and E. coli with nano-suspension of Chrysanthemum coronarium, and 12.09 +/- 0.11 and 14.10 +/- 0.49 mm with nano-suspension of Azadirachta indica, respectively. It is concluded that individual nano-suspensions showed better pesticidal as well as antimicrobial activities than combinations. However, the constructed nanosuspension can be applied to control the plant pests and diseases simultaneously
