Eugenol-Loaded Transethosomal Gel for Improved Skin Delivery and Treatment of Atopic Dermatitis.

Atopic dermatitis is a skin condition characterized by lichenification (thickening and increased skin marking), eczematous lesions, dry skin, itching, and pruritus. Eugenol is an aromatic polyphenolic compound that has attracted the attention of researchers due to its anti-inflammatory, anti-oxidant, and anti-cancer properties. The primary goal of the present study was to develop and evaluate eugenol-loaded transethosomes for the treatment of AD. Eugenol-loaded transethosomes were formulated using the ethanol injection method and subsequently subjected to particle size analysis, zeta potential, entrapment efficiency, deformability index, and HRTEM analysis. Transethosomal gel was prepared by direct-dispersion method by using Carbopol 940®. Results showed transethosomes to be lipid bilayer structures with acceptable size, and high entrapment efficiency. Transethosomal formulation showed shear-thinning behavior. Eugenol-loaded transethosomal gel was significantly able to enhance the retention of the drug in the skin. Transethosomal gel was significantly able to reduce Ear thickness, DLC, TLC, and IL-6 levels in mice model of AD. These results indicate that the eugenol-loaded transethosomal gel could be a promising carrier for the topical administration of eugenol for the treatment of AD.

Potential of green-synthesized ZnO NPs against human ovarian teratocarcinoma: an in vitro study.

BACKGROUND: Ovarian cancer leads to devastating outcomes, and its treatment is highly challenging. At present, there is a lack of clinical symptoms, well-known sensitivity biomarkers, and patients are diagnosed at an advanced stage. Currently, available therapeutics against ovarian cancer are inefficient, costly, and associated with severe side effects. The present study evaluated the anticancer potential of zinc oxide nanoparticles (ZnO NPs) that were successfully biosynthesized in an ecofriendly mode using pumpkin seed extracts. METHODS AND RESULTS: The anticancer potential of the biosynthesized ZnO NPs was assessed using an in vitro human ovarian teratocarcinoma cell line (PA-1) by well-known assays such as MTT assay, morphological alterations, induction of apoptosis, measurement of reactive oxygen species (ROS) production, and inhibition of cell adhesion/migration. The biogenic ZnO NPs exerted a high level of cytotoxicity against PA-1 cells. Furthermore, the ZnO NPs inhibited cellular adhesion and migration but induced ROS production and cell death through programmed cell death. CONCLUSION: The aforementioned anticancer properties highlight the therapeutic utility of ZnO NPs in ovarian cancer treatment. However, further research is recommended to envisage their mechanism of action in different cancer models and validation in a suitable in vivo system.

Screening of Cu4 O3 NPs efficacy and its anticancer potential against cervical cancer.

Cu4 O3 is the least explored copper oxide, and its nanoformulation is anticipated to have important therapeutic potential especially against cancer. The current study aimed to biosynthesize Cu4 O3 nanoparticles (NPs) using an aqueous extract of pumpkin seeds and evaluate its antiproliferative efficacy against cervical cells after screening on different cancer cell lines. The obtained NPs were characterized by different spectroscopic analyses, such as UV-vis, thermogravimetric, energy dispersive X-ray, and Fourier-transform infrared spectroscopy (FTIR). In addition, high-resolution transmission electron microscopes (HR-TEM) were used to observe the morphology of the biosynthesized NPs. The UV-vis spectra showed a peak at around 332 nm, confirming the formation of Cu4 O3 NPs. Moreover, FTIR and TAG analyses identified the presence of various bioactive phytoconstituents that might have worked as capping and stabilization agents and comparative stable NPs at very high temperatures, respectively. The HR-TEM data showed the spherical shape of Cu4 O3 NPs in the range of 100 nm. The Cu4 O3 NPs was screened on three different cancer cell lines viz., Hela, MDA-MB-231, and HCT-116 using cytotoxicity (MTT) reduction assay. In addition, Vero was taken as a normal epithelial (control) cell. The high responsive cell line in terms of least IC50 was further assessed for its anticancer potential using a battery of biological tests, including morphological alterations, induction of apoptosis/ROS generation, regulation of mitochondrial membrane potential (MMP), and suppression of cell adhesion/migration. Vero cells (control) showed a slight decline in % cell viability even at the highest tested Cu4 O3 NPs concentration. However, all the studied cancer cells viz., MDA-MB-231, HCT 116, and HeLa cells showed a dose-dependent decline in cell viability after the treatment with Cu4 O3 NPs with a calculated IC50 value of 10, 11, and 7.2 µg/mL, respectively. Based on the above data, Hela cells were chosen for further studies, that showed induction of apoptosis from 3.5 to 9-folds by three different staining techniques acridine orange/ethidium bromide (AO/EB), 4',6-diamidino-2-phenylindole (DAPI), and propidium iodide (PI). The enhanced production of reactive oxygen species (>3.5-fold), modulation in MMP, and suppression of cell adhesion/migration were observed in the cells treated with Cu4 O3 NPs. The current study obtained the significant antiproliferative potential of Cu4 O3 NPs against the cervical cancer cell line, which needs to be confirmed further in a suitable in vivo model. Based on our results, we also recommend the green-based, eco-friendly, and cost-effective alternative method for synthesizing novel nanoformulation.

In vitro antidiabetic, antioxidant, antimicrobial, and cytotoxic activity of Murraya koenigii leaf extract intercedes ZnO nanoparticles.

Nanotechnology is an emerging field with tremendous potential and usage of medicinal plants and green preparation of nanoparticles (NPs) is one of the widely explored areas. These have been shown to be effective against different biological activities such as diabetes mellitus, cancer, antioxidant, antimicrobial, etc. The current studies focus on the green synthesis of zinc NPs (ZnO NPs) from aqueous leaf extract of Murraya koenigii (MK). The synthesized Murraya koeingii zinc oxide NPs (MK ZnO NPs) were characterized using UV-visible spectroscopy, dynamic light scattering (DLS), Fourier transform infrared (FTIR) spectroscopy, field emission scanning electron microscopy (FESEM), energy-dispersive spectrum (EDS) and cyclic voltammetry (CV). The synthesized MK ZnO NPs were evaluated for their in vitro antidiabetic, antioxidant, antimicrobial, and cytotoxic activity. They demonstrated significant antidiabetic and cytotoxic activity, as well as moderate free-radical scavenging and antibacterial activity.

Epidermolysis Bullosa Acquisita in a patient with End Stage Renal Disease: Case study.

The clinical presentation of COVID-19 varies from being asymptomatic to developing acute respiratory distress syndrome and multi-organ dysfunction. The diffuse microvascular thrombi in multiple organs seen in the autopsy of COVID-19 patients are similar to that of thrombotic microangiopathy (TMA). TMA is characterised by thrombus formation in the microvasculature with laboratory findings of microangiopathic haemolytic anaemia (MAHA) and thrombocytopenia. A 49-year-old male presented to the Aga Khan University Hospital, Karachi. with fever, diarrhoea, altered level of consciousness, and a positive nasopharyngeal swab for SARS-CoV-2. He developed severe thrombocytopenia, MAHA with 5.8% schistocytes, and worsening renal function on the sixth day of admission. Diagnosis of thrombotic thrombocytopenic purpura (TTP) was established based on PLASMIC score, and he was successfully treated with intravenous (IV) Methylprednisolone, therapeutic plasma exchange and IV Rituximab. The case emphasises the need to keep TTP in the differential diagnosis when a patient with COVID-19 develops severe thrombocytopenia, acute renal failure, or impaired level of consciousness, since prompt diagnosis and treatment is necessary to gain favourable outcome.

HoloMentor: A Novel Mixed Reality Surgical Anatomy Curriculum for Robot-Assisted Radical Prostatectomy.

OBJECTIVES: The disruption to surgical training and medical education caused by the global COVID-19 pandemic highlighted the need for realistic, reliable, and engaging educational opportunities available outside of the operating theatre and accessible for trainees of all levels. This article presents the design and development of a virtual reality curriculum which simulates the surgical mentorship experience outside of the operating theatre, with a focus on surgical anatomy and surgical decision-making. METHOD: This was a multi-institutional study between London's King's College and Imperial College. The index procedure selected for the module was robotic radical prostatectomy. For each stage of the surgical procedure, subject-matter experts (N = 3) at King's College London, identified (1) the critical surgical-decision making points, (2) critical anatomical landmarks, and (3) tips and techniques for overcoming intraoperative challenges. Content validity was determined by an independent panel of subject-matter experts (N = 8) at Imperial College, London, using Fleiss' kappa statistic. The experts' teaching points were combined with operative footage and illustrative animations, and projected onto a virtual reality headset. The module was piloted to surgical science students (N = 15). Quantitative analysis compared participants' confidence regarding their anatomical knowledge before and after taking the module. Qualitative data were gathered from students regarding their views on using the virtual reality model. RESULTS: Multi-rater agreement between experts was above the 70.0% threshold for all steps of the procedure. Seventy-three percentage of pilot study participants "agreed" or "strongly agreed" that they achieved a better understanding of surgical anatomy and the rationale behind each procedural step. This was reflected in an increase in the median knowledge score after trialing the curriculum (p < 0.001). 100% of subject-matter experts and 93.3% of participants "agreed" or "strongly agreed" that virtual mentorship would be useful for future surgical training. CONCLUSIONS: This study demonstrated that virtual surgical mentorship could be a feasible and cost-effective alternative to traditional training methods with the potential to improve technical skills, such as operative proficiency and nontechnical skills such as decision-making and situational judgement.

Biological Activity of Picrorhiza kurroa: A Source of Potential Antimicrobial Compounds against Yersinia enterocolitica.

Yersiniosis, caused by Yersinia enterocolitica, is the third most rampant zoonotic disease in Europe; the pathogen shows high antibiotic resistance. Herbs have multiple anti-microbial components that reduce microorganism resistance. Therefore, an extract of Picrorhiza kurroa (P. kurroa) was evaluated for potential antimicrobial activity. We report that the ethanolic extract of P. kurroa showed effective antimicrobial activity (zone of inhibition: 29.8 mm, Minimum inhibitory concentration (MIC): 2.45 mg/mL, minimum bactericidal concentration (MBC): 2.4 mg/mL) against Yersinia enterocolitica. Potential bioactive compounds from P. kurroa were identified using LC-MS, namely, cerberidol, annonidine A, benzyl formate, picroside-1, and furcatoside A. P. kurroa showed effective antimicrobial potential in skim milk at different pH, acidity, and water activity levels. P. kurroa affected the physiology of Yersinia enterocolitica and reduced the number of live cells. Yersinia enterocolitica, when incubated with P. kurroa extract, showed lower toxin production. Picroside-1 was isolated and showed higher antimicrobial potential in comparison to the standard antibiotic. Picroside-1 lysed the Yersinia enterocolitica cells, as observed under scanning electron microscopy. Docking revealed that picroside-1 (ligand) showed both hydrophilic and hydrophobic interactions with the dihydrofolate reductase (DHFR) protein of Yersinia enterocolitica and that DHFR is a possible drug target. The high activity and natural origin of Picroside-1 justify its potential as a possible drug candidate for Yersinia enterocolitica.

Targeting Glutaminase by Natural Compounds: Structure-Based Virtual Screening and Molecular Dynamics Simulation Approach to Suppress Cancer Progression.

Cancer cells change their glucose and glutamine (GLU) metabolism to obtain the energy required to continue growing. Glutaminase (GLS) plays a crucial role in promoting cell metabolism for cancer cell growth; targeting GLU metabolism by inhibiting GLS has attracted interest as a potential cancer management strategy. Herein, we employed a sequential screening of traditional Chinese medicine (TCM) database followed by drug-likeness and molecular dynamics simulations against the active site of GLS. We report 12 potent compounds after screening the TCM database against GLS, followed by a drug-likeness filter with Lipinski and Veber rule criteria. Among them, ZINC03978829 and ZINC32296657 were found to have higher binding energy (BE) values than the control compound 6-Diazo-5-Oxo-L-Norleucine, with BEs of -9.3 and -9.7 kcal/mol, respectively, compared to the BE of 6-Diazo-5-Oxo-L-Norleucine (-4.7 kcal/mol) with GLS. Molecular dynamics simulations were used to evaluate the results further, and a 100 ns MD simulation revealed that the hits form stable complexes with GLS and formed 2-5 hydrogen bond interactions. This study indicates that these hits might be employed as GLS inhibitors in the battle against cancer. However, more laboratory tests are a prerequisite to optimize them as GLS inhibitors.

S. Typhi derived vaccines and a proposal for outer membrane vesicles (OMVs) as potential vaccine for typhoid fever.

Typhoid fever is a serious systemic infection caused by Salmonella Typhi (S. Typhi), spread by the feco-oral route and closely associated with poor food hygiene and inadequate sanitation. Nearly 93% of S. Typhi strains have acquired antibiotic resistance against most antibiotics. Vaccination is the only promising way to prevent typhoid fever. This review covers the nature and composition of S. Typhi, pathogenecity and mode of infection, epidemiology, and nature of drug resistance. Several components (Vi-polysaccharides, O-antigens, flagellar antigens, full length OMPs, and short peptides from OMPs) of S. Typhi have been utilized for vaccine design for protection against typhoid fever. Vaccine delivery systems also contribute to efficacy of the vaccines. In this study, we propose to develop S. Typhi derived OMVs as vaccine for protection against typhoid fevers.

Effect of processing conditions on the stability of native vitamin A and fortified retinol acetate in milk.

The objective of this investigation was to evaluate the stability of vitamin A in fortified milk which was exposed to different processing conditions viz. heat treatments (pasteurization, boiling and sterilization), light exposure treatments (1485, 2970 and 4455 lux for 2, 4, 8, 16 and 32 h) and different packaging materials (polyethylene pouches and glass bottles) and also to evaluate the effect of fortified iron (ferric pyrophosphate soluble (FPP) and ferrous gluconate hydrate (FG) on vitamin A stability during processing and storage. Toned milk was fortified with 25 ppm iron and vitamin A acetate 2500 IU/L, singly and also in combination. The vitamin A analysis method was optimized and accuracy and precision were below ± 5%. The results indicated that vitamin A was heat-labile and its degradation increased with the increase in the intensity of heat treatments. Pasteurized milk (318.11 IU/L) showed non-significant (p > 0.05) decrease, however, boiling (250.21 IU/L) and sterilization (205.65 IU/L) showed a significant difference (p < 0.05) in vitamin A content in comparison to control (324.71 IU/L). Similarly, vitamin A was light sensitive and its degradation significantly increased (p < 0.05) with an increase in the intensity of light exposure (34.82 to 92.53%). Loss of vitamin A (%) was significantly greater (p < 0.05) in iron-fortified milk suggesting that iron might have played a role in accelerating the degradation of vitamin A. Extent of losses were significantly higher (p < 0.05) in FG compared to FPP fortified milk. Vitamin A (microencapsulated form) which was added externally was more stable than the inherent vitamin A present in milk.

Antibacterial and Antifungal Studies of Biosynthesized Silver Nanoparticles against Plant Parasitic Nematode Meloidogyne incognita, Plant Pathogens Ralstonia solanacearum and Fusarium oxysporum.

The possibility of using silver nanoparticles (AgNPs) to enhance the plants growth, crop production, and control of plant diseases is currently being researched. One of the most effective approaches for the production of AgNPs is green synthesis. Herein, we report a green and phytogenic synthesis of AgNPs by using aqueous extract of strawberry waste (solid waste after fruit juice extraction) as a novel bioresource, which is a non-hazardous and inexpensive that can act as a reducing, capping, and stabilizing agent. Successful biosynthesis of AgNPs was monitored by UV-visible spectroscopy showing a surface plasmon resonance (SPR) peak at ~415 nm. The X-ray diffraction studies confirm the face-centered cubic crystalline AgNPs. The scanning electron microscopy (SEM) and transmission electron microscopy (TEM) techniques confirm the rectangular shape with an average size of ~55 nm. The antibacterial and antifungal efficacy and inhibitory impact of the biosynthesized AgNPs were tested against nematode, Meloidogyne incognita, plant pathogenic bacterium, Ralstonia solanacearum and fungus, Fusarium oxysporum. These results confirm that biosynthesized AgNPs can significantly control these plant pathogens.

Post renal transplant polycythemia and treatment: A single center study.

OBJECTIVE: To calculate the incidence of post-transplant erythrocytosis, and to assess the response to treatment. METHODS: The prospective study was conducted from April 2016 to April 2018 at the Department of Nephrology, Bahria International Hospital, Lahore, Pakistan, and comprised patients undergoing renal transplantation who were evaluated and followed up for 12 months. Patients having haemoglobin levels ≥17gm/dl were labelled as having polycythemia. Data was analysed using SPSS 21. RESULTS: Of the 94 total patients, 69(73.4%) were enrolled. During follow-up, 2(2.9%) of them died, and, thus, the final sample stood at 67(71.3%); 57 (85%) males and 10(15%) females. The mean age of the sample was 32.6±8.8 years. Overall, 19(28.4%) patients developed polycythemia and they were either given angiotensin-converting enzyme inhibitors or angiotensin II receptor blockers. Of these 19 patients, 11(57.8 %) responded to the treatment, while 8(42.1%) required phlebotomy. Further, 3(15.7%) patients required one phlebotomy, while 5(26.3%) who had glomerular filtration rate >30% had to have repeated phlebotomy. CONCLUSIONS: The incidence of post-transplant erythrocytosis was significantly high at 28.4%.

Atypical haemolytic uraemic syndrome and its treatment: A case report.

Atypical Haemolytic Uraemic Syndrome (aHUS) is considered an uncommon pathology that usually affects young adults and causes acute kidney injury which can further lead to End Stage Renal Disease (ESRD). Here we present the case of a previously healthy young boy who was diagnosed as a case of atypical HUS on renal biopsy in Sheikh Zayed Hospital Lahore. His C3 was low, while ANA and C-ANCA P-ANCA were in normal range; multiple sessions of plasmapheresis were conducted, whereas IV Methylprednisolone was also given during both admissions (the patient had to be readmitted six months later after having been discharged on improvement). After that, his GFR improved along with other laboratory parameters. Rituximab was also offered but the family refused due to affordability issue.

Inter-Parental Conflict's Persistent Effects on Adolescent Psychological Distress, Adjustment Issues, and Suicidal Ideation During the COVID-19 Lockdown.

The current study sought to ascertain the impact of inter-parent conflicts on teenage psychological distress, social and academic adjustment and examine the suicide ideation during the COVID-19. The results found to be alarming as 22% of the individuals displayed suicidal tendencies, with 9% having attempted suicide once, 4.6% having tried suicide twice, and 11% stating that they were likely to do so again. Therefore, the media and the government might host awareness programs and counseling initiatives to promote mental health and prevent suicidal behavior. Moreover, parents may be educated on community level, about the effect of inter-parental arguments on the mental health of their children.

Anti-obesity efficacy of the selected high altitude Himalayan herbs: in vitro studies.

Obesity is a serious health problem for all age groups and it also promotes Type 2 diabetes, cardiovascular diseases, cancer and hypertension. Herbs are used for the weight reduction from ancient times, therefore, 12 herbs viz. Betula utilis, Bunium periscum, Angelica glauce, Saussurea lappa, Podophyllum hexandrum, Bergenia ciliate, Rumex acetosa, Aconitum heterophyllum, Centella asiatica, Andrographis paniculata, Dactylorhiza hatagirea and Bauhina variegate were selected as per literature. Rumex acetosa roots showed the highest extraction rate (39.5%), while C. asiatica leaf showed lowest extraction rate (1.25%) as compared to other herbs. As well, S. lappa leaf extract (396.52 mg GAE/g), R. acetosa root extract (181.5 mg QE/g), and B. ciliate leaf extract (79.19%) showed significantly higher Total Phenolic Content, Total Flavonoid Content and antioxidant activity, respectively. Furthermore, lipase and amylase inhibition activity and IC50 value of herb extract were higher in S. lappa root extract (75.75%, 75.41% and 62.47, 61.37, respectively). Bauhina variegate leaf extract showed a significantly higher glucose level, percentage of glucose movement (1.446 mg/dL and 63.85%) and (0.938 mg/dL and 76.55%). Based upon these experiments, 5 herbs were selected and different formulations were prepared and out of these, F3 herb formulation showed higher lipase and amylase inhibition activity (81.75% and 70.66%) and therefore, F3 herbal formulation was selected for treatment of obesity.

S.Typhi derived OmpC peptide conjugated with Vi-polysaccharide evokes better immune response than free Vi-polysaccharide in mice.

Salmonella typhi is a causative organism for typhoid fever. Free Vi capsular polysaccharide (Vi) is licensed for use as vaccine for typhoid fever in individuals 2 years of age and older, which has limited memory response. There is dire need of protein or peptide as conjugate partner with Vi polysaccharide to improve shortcomings of Vi vaccine. Prediction of immunogenic peptide was deduced by program T sites. Carbodiimide mediated conjugation of Vi polysaccharide with OmpCp was performed utilizing ADH as linker. Immune response of Vi-conjugates along with control group was tested in mice. Ig and IgG antibodies against Vi polysaccharide was measured by ELISA. Two immunodominant regions (loop number 3a and 7) with high content of T-cell epitopes from OmpC was selected and synthesized. Vi poly/OmpCp ratios in Vi-conjugates were ~0.43-0.65. Vi polysaccharide alone elicited very low levels of Vi antibody without any booster effect. Vi-conjugate evoked 20-fold higher immune response compared to free Vi. Further, adequate levels of IgG antibodies were induced only by the Vi-conjugate suggesting that T-helper cells had been induced. Our data suggest that selected short peptide (OmpCp)as a carrier with Vi polysaccharide is assumed to be a promising molecule for candidate vaccine for typhoid fever.
