Abstract
Bayesian Control charts are emerging as the most efficient statistical tools for monitoring manufacturing processes and providing effective control over process variability. The Bayesian approach is particularly suitable for addressing parametric uncertainty in the manufacturing industry. In this study, we determine the monitoring threshold for the shape parameter of the Inverse Gaussian distribution (IGD) and design different exponentially-weighted-moving-average (EWMA) control charts based on different loss functions (LFs). The impact of hyperparameters is investigated on Bayes estimates (BEs) and posterior risks (PRs). The performance measures such as average run length (ARL), standard deviation of run length (SDRL), and median of run length (MRL) are employed to evaluate the suggested approach. The designed Bayesian charts are evaluated for different settings of smoothing constant of the EWMA chart, different sample sizes, and pre-specified false alarm rates. The simulative study demonstrates the effectiveness of the suggested Bayesian method-based EWMA charts as compared to the conventional classical setup-based EWMA charts. The proposed techniques of EWMA charts are highly efficient in detecting shifts in the shape parameter and outperform their classical counterpart in detecting faults quickly. The proposed technique is also applied to real-data case studies from the aerospace manufacturing industry. The quality characteristic of interest was selected as the monthly industrial production index of aircraft from January 1980 to December 2022. The real-data-based findings also validate the conclusions based on the simulative results.

Abstract
Background The pharmaceutical sector in Pakistan has grown over a period, however, there are several barriers in the framework governing the growth of the country's pharmaceuticals. The lack of academia-industry linkage (AIL) is among the critical barriers; hence the focus of the study is to find out the reasons for the lack in the above collaboration. Understanding barriers may help their redressal. Method This qualitative phenomenology-based study has been conducted in the most prominent pharmacy institutes, located in Lahore, Islamabad, Peshawar, Sargodha, and Quetta. Academic participants, with a minimum experience of 10 years and designation of assistant professor or above were recruited with a two-stage selection process, purposive sampling and snowball sampling. The data were collected using semi-structured interviews with academic experts. Thematic content analysis was employed to conclude the data. Results Analysis of data yielded 8 themes with 18 codes. The main reasons for neglected AIL were explained by a partial or complete lack of industrial research and development activities. Other key factors for the scarcity of AILs were the lack of positive attitude from both industry and academia, applied research in academics, and the research and development of the new molecules in the pharmaceutical industry. Support by the government and the drug regulatory authority of Pakistan in terms of regulatory and academic policies was also perceived to be absent. New horizons in research and development could be opened by providing applied research to industry, including but not limited to new molecule development. Conclusion Academia-industry linkage could be boosted with government-backed funded projects and policies. Academia should focus on the industrial-demanded applied research.

Abstract
Lyophilized human amniotic membrane (HAM) and silver nanoparticles (AgNPs) have multispectral applications as a biological dressing. The present study focuses on the safety aspects of HAM coated with colistin and AgNPs (HACoN) dressing in relation to its structural and hematological changes. Four dressing groups were designed for the study, HAM, HAM coated with colistin (HACo), HAM coated with AgNPs (HAN), and HAM coated with colistin (HACo) and HACoN. Scanning electron microscopy (SEM) and Fourier-transform infrared spectroscopy (FTIR) were utilized for constitutional analysis. Biological safety was checked by applying HAM of all groups on open excisional burn wounds on Sprague-Dawley rats for 21 days. The skin, kidneys, liver, and spleen were removed, and histological analysis was performed for detailed structural analysis. Oxidative stress was assessed using homogenate from newly generated skin. No structural or biochemical change was observed in any of the study groups as observed by SEM and FTIR. After 21 days of grafting, wounds were healed properly with normal skin, and no anomaly was observed in related to kidneys, spleen, and liver. Some of antioxidant enzymes were increased, while malondialdehyde which is a reactive oxygen species was reduced in the skin tissue homogenate of HACoN group. Impregnation of colistin and AgNPs in combination on HAM has no effects on hematological and structural constitution of HAM. It leaves no obvious change in vital organs of rats and improves oxidative stress and inflammation. Hence, it can be claimed that HACoN is a biologically safe antibacterial dressing.

Abstract
BACKGROUND Allogeneic hepatocyte transplantation is an emerging approach to treat acute liver defects. However, durable engraftment of the transplanted cells remains a daunting task, as they are actively cleared by the recipient's immune system. Therefore, a detailed understanding of the innate or adaptive immune cells-derived responses against allogeneic transplanted hepatic cells is the key to rationalize cell-based therapies. METHODS Here, we induced an acute inflammatory regenerative niche (3-96 h) on the surface of the liver by the application of cryo-injury (CI) to systematically evaluate the innate immune response against transplanted allogeneic hepatic progenitors in a sustained micro-inflammatory environment. RESULTS The resulting data highlighted that the injured site was significantly repopulated by alternating numbers of innate immune cells, including neutrophils, monocytes and Kupffer cells (KCs), from 3 to 96 h. The transplanted allo-HPs, engrafted 6 h post-injury, were collectively eliminated by the innate immune response within 24 h of transplantation. Selective depletion of the KCs demonstrated a delayed recruitment of monocytes from day 2 to day 6. In addition, the intrasplenic engraftment of the hepatic progenitors 54 h post-transplantation was dismantled by KCs, while a time-dependent better survival and translocation of the transplanted cells into the injured site could be observed in samples devoid of KCs. CONCLUSION Overall, this study provides evidence that KCs ablation enables a better survival and integration of allo-HPs in a sustained liver inflammatory environment, having implications for rationalizing the cell-based therapeutic interventions against liver defects.

Abstract
Ulcerative colitis (UC) is a chronic inflammatory bowel disease characterized by inflammation and ulceration of the colon and rectum. Diet is an important part of UC management because it can either aggravate or alleviate symptoms along with medication therapy. A comprehensive literature search was conducted using multiple databases (PubMed and Online Wiley Library) and search engines (Google Scholar) using specific keywords related to UC and diet. The search resulted in a large number of articles, which were then narrowed down by focusing on clinical trials and randomized controlled trials published between 2010 and 2023. According to the research, certain dietary interventions, such as the low FODMAP diet, the Mediterranean diet, and the anti-inflammatory diet, appear to improve symptoms and overall quality of life. Dietary interventions have the potential to help with UC management. The goal should be to provide patients with tailored dietary interventions and other treatments to improve their quality of life. More research is needed to identify the most effective dietary interventions and better understand how they work.

Abstract
The aim of this study was to fabricate celecoxib-loaded chitosan/guar gum (CS/GG) single (SC) and dual (DC) crosslinked hydrogel beads using the ionotropic gelation approach. The prepared formulations were evaluated for entrapment efficiency (EE%), loading efficiency (LE%), particle size and swelling studies. The performance efficiency was assessed by in vitro drug release, ex-vivo mucoadhesion, permeability, ex-in vivo swelling and in vivo anti-inflammatory studies. The EE% was found to be ~55% and ~44% for SC5 and DC5 beads, respectively. The LE% was ~11% and ~7% for SC5 and DC5 beads, respectively. The beads showed a matrix-like network with thick fibers. The particle size of beads ranged from ~2.74 to 1.91 mm. About 74% and 24% celecoxib was released from SC and DC hydrogel beads, respectively, within 24 h. The SC formulation showed higher %swelling and permeability than the DC counterpart, while the %mucoadhesion was relatively higher for DC beads. During the in vivo study, a significant decrease in the inflammation of the rat paw and inflammatory markers including C-reactive proteins (CRP) and interleukin-6 (IL-6) was observed following treatment with the prepared hydrogel beads; however, the SC formulation showed better therapeutic efficiency. In conclusion, celecoxib-loaded crosslinked CS/GG hydrogel beads can provide sustained drug release and act as potential candidates for managing inflammatory conditions.

Abstract
Agarose (AG) is a naturally occurring biocompatible marine seaweed extract that is converted to hydrocolloid gel in hot water with notable gel strength. Currently, its mucoadhesion properties have not been fully explored. Therefore, the main aim of this study was to evaluate the mucoadhesive potential of AG binary dispersions in combination with Carbopol 934P (CP) as mucoadhesive gel preparations. The gels fabricated via homogenization were evaluated for ex vivo mucoadhesion, swelling index (SI), dissolution and stability studies. The mucoadhesive properties of AG were concentration dependent and it was improved by the addition of CP. Maximum mucoadhesive strength (MS) (27.03 g), mucoadhesive flow time (FT) (192.2 min), mucoadhesive time in volunteers (MT) (203.2 min) and SI (23.6% at 4 h) were observed with formulation F9. The mucoadhesive time investigated in volunteers (MT) was influenced by AG concentration and was greater than corresponding FT values. Formulations containing 0.3%, w/v AG (F3 and F9) were able to sustain the release (~99%) for both drugs till 3 h. The optimized formulation (F9) did not evoke any inflammation, irritation or pain in the buccal cavity of healthy volunteers and was also stable up to 6 months. Therefore, AG could be considered a natural and potential polymer with profound mucoadhesive properties to deliver drugs through the mucosal route.

Abstract
BACKGROUND The dissolution method for certain drugs needs specialized conditions. Dissolution testing for felodipine extended release (ER) tablets (Plendil® 5mg) and amlodipine-indapamide fixed dose (Natrilam®, 5/1.5 mg) ER tablets require the use of a stationary (felodipine) basket in USP Apparatus II. OBJECTIVE The study aimed to develop simple methods for Plendil® and Natrilam® without the use of a felodipine basket. METHOD The dissolution profiles obtained from different media and paddle speeds were used to compute miscellaneous dissolution parameters and were compared to those obtained from standard (existing) methods using a felodipine basket. RESULTS The f1, f2, and bootstrap f2 (5th % percentile) values for Plendil® were 2.47, 88.17, and 54.62, respectively, while all other dissolution factors revealed similarity between standard and the selected test method with 1% Tween 20 at 50 rpm. For Natrilam®, f1 and f2 and bootstrap f2 were 5.13, 72.92, and 62.67, respectively and all other dissolution parameters were also similar for the standard and selected test method using 0.1N HCl media having 0.38gm/L EDTA with a sinker at 100 rpm. Release of products assumed zero order and Weibull model, respectively. CONCLUSION Test dissolution methods for Plendil® and Natrilam® tablets produced equivalent dissolution profiles compared to standard methods with stationary basket USP Apparatus II.

Abstract
Antimicrobials used to treat burn wound infections have become multidrug-resistant, thus delaying wound healing. When combined with silver nanoparticles, antibiotics create a multifaceted antibacterial mechanism of action to which bacteria are incapable of developing resistance. Similarly, the amniotic membrane has been found to lower the bacterial number. The purpose of the current study was to observe the antibacterial activity of combined topical colistin with silver nanoparticles and decellularized human amniotic membrane as a dressing in burn wounds infected with bacteria with the goal of promoting faster healing. Bacteria commonly isolated from burn wounds and the most sensitive topical antibiotic were identified. Colistin, silver nanoparticles and combined colistin with silver nanoparticles were impregnated into decellularized human amniotic membranes. These wound dressings were evaluated in third-degree multidrug-resistant bacterial infected thermal burns induced in rats. Out of a total of 708 pus samples from burn wounds, Pseudomonas aeruginosa was the most prevalent pathogen 308 (43.5%), followed by Klebsiella pneumoniae 300 (42.4%). Topical colistin was 100% sensitive for both bacteria. Overall, maximum wound contraction (p < 0.05), and increased collagen deposition (+++) with no isolation of bacteria from wound swabs were noted on day 21 for the combined colistin with silver nanoparticle-loaded human amniotic membrane dressing group. Our study concluded that the increased antimicrobial activity of the novel combination of colistin and silver nanoparticle-loaded decellularized human amniotic membrane manifested its potential as an effective burn wound dressing.

Abstract
The conventional dosage forms (tablets, capsules), of ibuprofen has less potential in suppression of pain and inflammation due to their slow dissolution rates and lower bioavailability. Aim of this study was to fabricate fibrous solid dispersion of ibuprofen for improved dissolution rate and quick therapeutic action. Drug loaded microfibers were fabricated using centrifugal melt spinning (CMS) technique from the physical mixture of sucrose, ibuprofen and a hydrophilic polymer, PVP. These fibers were characterized by SEM, PXRD, DSC, and FTIR spectroscopy. The selected formulation was also pressed into tablets by direct compression method followed by its in-vitro and in-vivo characterization. The production yield of fibers was 75 ± 2% with an average diameter 15 ± 5 µm. The drug loading efficiency (DLE) was 85 ± 5%. The tablets dissolved rapidly (<40s). In-vitro dissolution studies have shown >85% of ibuprofen dissolved from tablet within first 2 min which was ∼5 times quicker than drug alone. Dissolution efficiency has improved from 0.63 of ibuprofen to 0.95 of that in fibers with ∼7 times reduction in mean dissolution time. PXRD, andDSC have shown amorphous state of ibuprofen in the formulation and FTIR spectra demonstrated no interaction of drug with excipients . In-vivo anti-inflammatory studies using rabbits revealed a significant (p <0.05) reduction in paw volume (mm) in the groups treated with fibrous formulation. This study concludes that microfibers produced by centrifugal melt spinning has improved dissolution rates and bioavailability of ibuprofen. Incorporation of polymer in the formulations improves the production yield and drug loading efficiency of microfibers.

Abstract
The study was aimed at designing and characterizing the ondansetron hydrochloride (OND) bearing agarose (AG), and hydroxypropyl methyl cellulose (HPMC) mucoadhesive buccal films employing glycerol as a plasticizer. The buccal delivery of ondansetron hydrochloride was remarkably boosted by employing physical (iontophoresis) and chemical enhancement approaches (chemical penetration enhancers). To explore the influence of different formulation components, i.e., agarose, hydroxypropyl methyl cellulose (HPMC), and glycerol on various evaluating parameters, i.e., tensile strength, swelling index, ex vivo mucoadhesion time, and subsequently on in vitro drug release, a D-optimal design was opted. A buccal film bearing OND was mounted on bovine buccal mucosa for ex vivo permeation studies and impact of chemical and physical enhancement techniques on the permeation profile was also analysed. A linear release profile was revealed in in vitro drug release of OND over 60 minutes and outcomes ascertained the direct relationship between HPMC content and in vitro drug release and inverse relationship was depicted by AG content. The FTIR and DSC thermal analysis was executed to determine the physicochemical interactions and results exposed no chemical interactions between drug and polymers. The drug (OND) appeared as tiny crystals on smooth film surface during scanning electron microscopy (SEM) analysis. A notable enhancement in permeation flux, i.e., 761.02 μg/min of OND during ex vivo permeation studies was witnessed after the application of current (0.5-1 mA) without any time lag and with enhancement ratio of 3.107. A time lag of 15 minutes, 19 minutes, and 26 minutes with permeation flux of 475.34 μg/min, 399.35 μg/min, and 244.81 μg/min was observed after chemical enhancer pretreatment with propylene glycol, Tween 80, and passive, respectively. Rabbit was employed as the experimental animal for pharmacokinetic studies (in vivo) and cats for pharmacological activity (in vivo), and the results illustrated the enhanced bioavailablity (2.88 times) in the iontophoresis animal group when compared with the rabbits of control group. Likewise, a remarkable reduction in emesis events was recorded in cats of iontophoresis group. Conclusively, the histopathological examinations on excised buccal mucosa unveiled no severe necrotic or cytopathetic outcomes of current.

Abstract
Lansoprazole (LPZ) show poor bioavailability because of first pass effect and absorption factors. The floating delivery systems could reduce fluctuations in plasma drug concentration through maintaining desirable plasma drug concentration. The objective of present study was to enhance bioavailability despite first pass effect through continuous availability of drug from floating system. Gum tragacanth (GT) and itaconic acid (IA) based floating hydrogels (FH) were synthesized. Parameters optimized were; microwave radiation exposure time, pH, GT:IA ratio and concentration of the glutaraldehyde. Optimized FH were evaluated for entrapment efficiency (% EE), in-vitro release, FTIR, SEM, and in- vitro and in-vivo floating study. Finally, pharmacokinetic was evaluated in ulcer-induced SD rats. Grafting percentage, swelling ratio and %EE of LPZ was 115%, ̴250% and 90%, respectively. Microwave radiation exposure time, pH of reaction medium, GT:IA ratios and cross linker concentration were 2 min, pH 5, ratios 2:1 and 0.02%, respectively. The optimized FH showed acceptable floating behavior. The X-ray images revealed that hydrogels remained floated over gastric contents up to 24 hours. The in-vitro release and pharmacokinetics revealed availability of LPZ upto to 24h in-vitro and in ulcer-induced SD rats, respectively. The present hydrogels based floating system of lansoprazole is capable to extend the gastric residence time upto 24 hours.

Abstract
The study aimed at simultaneous quantification of sumatriptan succinate (SUM) and prochlorperazine maleate (PCP) in an orodispersible film using two validated spectroscopic methods viz. simultaneous equation (Method I) and the Q-absorption ratio (Method II). The Method I involved measurement of absorbances at λmax of both drugs while in Method II, absorbances were measured at isosbestic wavelength and λmax of one of the two components. Method validation were accomplished as per the ICH guidelines. A 1:1 mixture of the drugs and an orodispersible film (ODF) containing these drugs were assayed by both methods. The absorbance data of SUM and PCP in both methods were linear at respective wavelengths with correlation coefficient values >0.995. Both methods were precise as % RSD in repeatability, interday and intraday precision was less than 2. The estimation of SUM and PCP from the film dosage form by method I was104.74% and 98.34% and by method II was 103.45% and 98.85%, respectively, with a standard deviation <2. The study concluded that both the methods were simple, reliable and robust and can be applied successfully for the simultaneous quantification of SUM and PCP in mixture and orodispersible film dosage form.

Abstract
While having access to safe and efficient vaccines is essential for eradicating the COVID-19 pandemic, gaining marketing authorisation is a critical step in enabling and speeding this process. On December 2, 2020, the United Kingdom became the first country to approve the first COVID-19 vaccine. This commentary aims to provide a quick overview of the UK’s COVID-19 vaccine authorization process and compare it to that of the EU and the US. While the UK, EU, and US expedited the COVID-19 vaccine approval process, regulatory authorities did not appear to cut corners in their approval of the Pfizer COVID-19 vaccine, as evidenced by their decisions to switch emergency use authorization to full authorization in the US and to renew conditional/temporary use authorization in the EU and UK, respectively. There is an opportunity to conduct a thorough investigation into and comparison of the filed dossiers, as well as the robustness of the evaluation process for the approval of COVID-19 vaccines.

Abstract
The limited solubility of clarithromycin (CAM), coupled with low bioavailability and rapid elimination, are major shortcomings, needed to be addressed to achieve optimum therapeutic goals. Therefore, sustained-release (SR) tablets containing solid dispersion (SD) granules of CAM were prepared in this study. Initially, SD granules of CAM were prepared by hot melt extrusion (HME) technique using Kollidon VA64 as a hydrophilic carrier. The saturation solubility of SD showed almost 4.5-fold increase as compared to pure CAM in pH 6.8 medium. In vitro drug dissolution data indicated a substantial increase in the dissolution of SD as compared to that of pure CAM. The thermal stability of drug, carrier, and SD at elevated HME temperatures was evident from the results of thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). Powder X-ray diffraction (PXRD) data and scanning electron microscope (SEM) images revealed a decrease in the crystallinity and the uniform dispersion of drug, respectively. Moreover, Fourier transformed infrared spectroscopy (FT-IR) data confirmed the formation of hydrogen bond between the carbonyl group of drug and the hydroxyl group of carrier. SD loaded sustained-release (SD-SR) matrix tablets were prepared with hydrophobic polymers (Eudragit RS100 and Eudragit RL100). The pH-independent swelling and permeability of both polymers were responsible for the sustained drug release from SD-SR tablets. Pharmacokinetic (PK) studies suggested a 3.4-fold increase in the relative bioavailability of SD-SR tablets as compared to that of pure CAM.

Abstract
ABSTRACT. In the present research, three zinc(II) complexes were synthesized using 3-(3-fluorophenyl)-2-methylacrylic acid (HL), 1,10-phenanthroline and 2,2'-pyridine as ligands. The composition, structural confirmation, coordination way of ligand and assignment of geometry to the complexes were made by different analytical tools like elemental analysis, FTIR and 1H-NMR. The ligand 3-(3-fluorophenyl)-2-methylacrylate appeared to coordinate the metal (Zn) atom via COO- moiety in all of the complexes (1-3) while 1,10-phenanthroline and 2,2'-pyridine co-ordinated to Zn(II) atom through N-donor sites in complexes 2 and 3, respectively. The complex 1 showed four while 2 and 3 showed six co-ordinated geometry. The synthesized complexes were evaluated for antimicrobial and cytotoxic activities. The obtained results showed that complexes are active against microbial agents and exhibited significant cytotoxicity.

Abstract
Poor bioavailability is a major obstacle in the development of an effective dosage form of the poorly soluble drugs. The present study aimed to improve the dissolution rate of a poorly soluble drug oxcarbazepine (OXC) exploiting the approach of surface area enhancement by fabricating drug loaded microfibers via centrifugal melt spinning (CMS) technique. For the generation of OXC loaded fibers, a well-known cotton candy process was used and the prepared fibers were characterized using SEM, DSC, XPRD and FTIR. Drug loaded fibers were also pressed into tablets which were also subjected to various in-vitro and in-vivo characterizations. The results have shown the formations of stable, amorphous, micro sized fibers, with average diameter of 6.0 ± 2 μm, loading efficiency > 80% and overall yield > 85%. In-vitro dissolution of OXC from fibers was > 90% within two minutes, which is ~ 5 times faster than that of pure drug. Pharmacokinetic data showed an improvement of ~ 25% and 35% in Cmax and AUC, respectively with two hours earlier Tmax. In-vivo studies in human oral cavity showed quick disintegration (45 ± 5 s) with > 90% OXC dissolved. The study concludes that the OXC incorporated in microfibers showed rapid in-vitro and in-vivo (oral) dissolution which resulted in rapid systemic absorption and improved bioavailability parameters. Furthermore, the addition of PVP boosted the extrusion process and stability of fibers and the sucrose base of these fibers has masked the taste of OXC making such formulation palatable, especially for pediatric patients.

Material and Method In the first phase, release controlling parameters of AML-B and SIM granules were identified and in the second phase a fixed dose AML-B and SIM tablet formulation was prepared and optimized for a differential release of the drugs using a quality by design (QbD) and risk assessment approach. A validated HPLC method was employed for simultaneous determination of AML-B and SIM for FDC formulation. A pharmacokinetics of the above drugs was studied in healthy dogs in the third phase. Results In QbD-based optimized formulation, Eudragit® RSPO-dicalcium phosphate (DCP) blend controlled the release of AML-B over 8 h, though this diffusion-controlled release assumed first order kinetics. DCP and Eudragit® RS 100 also retarded release of SIM causing SIM release over 8 h after AML-B release from the optimized FDC tablet formulation. The HPLC retention times of AML-B and SIM were 2.10 and 15.52 min, respectively. Linearity for AML-B was 5.0–50 ng/mL and 0.01–2.0 µg/mL for SIM with percent recoveries of 92.85–101.53% and 94.51–117.75% for AML-B and SIM. AUC0-∞ of AML-B was increased 3 fold, while AUC0-∞ of SIM was decreased 2 fold. The tmax values for AML-B and SIM were 12 and 6 h, respectively. AML-B was absorbed without any lag time (tlag) while tlag was 6.33 ± 0.81 h for SIM, thus met the study objective. Conclusion The pharmacokinetic study showed an immediate absorption of AML-B while that of SIM was withheld for 6 h, close to the desired delay time of 8 h.

Abstract
Purpose: To investigate in vitro antioxidant and anti-diabetic potentials of Fagonia indica Burm.f. Var. indica in order to provide scientific evidence for its traditional use.
Methods: Cold maceration method was employed for the preparation of extracts of aerial parts of the plant using chloroform, n-hexane, methanol and water as solvents. Total flavonoid and polyphenolic content of various extracts were determined by standard methods. The antioxidant and anti-diabetic activities of the extracts were determined using 1, 1-diphenyl-2-picrylhydrazyl (DPPH) and in vitro αglucosidase (maltase) inhibitory assays, respectively.
Results: Preliminary results indicated the presence of various phytochemicals in the extracts. The chloroform extract exhibited the highest contents of total flavonoids (65.98 ± 1.63 mg QE/g) and polyphenols (26.75 ± 1.09 mg GAE/g). This extract also showed the highest free radical scavenging (64.74 ± 1.43 %) with IC50 value of 34.18 ± 5.57 µg/mL while the methanol extract exerted the highest αglucosidase (maltase) inhibitory activity (45.22 ± 0.46 %) with half-maximal concentration (IC50) of 220.4 ± 0.41 µg/mL.
Conclusion: The extracts of the aerial parts of Fagonia indica possess significant anti-diabetic and antioxidant effect, thus justifying the traditional use of the plant for treatment of diabetes.

Abstract
Purpose: To develop a method for the measurement of carbon dioxide (CO2) released from effervescent formulations.
Methods: Effervescent granules were prepared using sodium bicarbonate and citric acid by fusion and solvent-assisted granulation methods. The amount of CO2 released was determined from the maximum pressure of gas release, time profile of pressure gradient using modified Chittick apparatus and gravimetric changes following effervescence.
Results: The amount of CO2 released from effervescent granules prepared by fusion method was 8.125, 8.763 and 7.98 mM/g measured by ideal gas equation, pressure gradient and gravimetric method, respectively. The formulation prepared by solvent-assisted granulation showed 5.525, 5.475 5.36 mM/g of carbon dioxide measured by the above three methods, respectively. The effervescent granules prepared by fusion method showed approximately 2 % loss in effervescence. However, approximately 39 % loss in effervescence was observed for the formulation prepared by solventassisted granulation. The commercial products showed a loss in effervescence in the range of 5 - 15%.
Conclusion: Modified Chittick’s apparatus is a useful analytical tool for monitoring of the CO2 from effervescent granules as a function of method of preparation.

Abstract
In the present study nanotechnology approach, i.e., a cyclodextrin (CD) based carbonate nanosponge was used to improve the solubility and dissolution of ibuprofen. Solvent and ultrasound assisted methods were used to prepare nanosponges using two CDs (β-CD and 2-hydroxypropyl-β-CD (2HP-β-CD)) and a cross-linker (CL) diphenyl carbonate (DPC) in varying molar ratios. Nanosponges were investigated for their solubilizing efficiency and phase solubility studies. Structural analysis by Fourier transform infrared (FTIR) and powder X-ray diffraction (PXRD), thermo-analytical characterization by differential scanning calorimetry (DCS), morphology by scanning electron microscopy (SEM). In-vitro drug release followed by in-vivo analgesic and anti-inflammatory studies were performed. 2HP-β-CD based nanosponges (molar ratio 0.01:0.04) prepared by ultrasound assisted method showed the highest solubilizing efficiency (i.e., 4.28 folds). Stability constant values showed that all complexes were stable. Inclusion complexes of drug was confirmed by PXRD and DSC. SEM images showed porous structures confirming the formation of cross-linked network. Particle size was in the range of 296.8±64 to 611.7±32nm. In-vitro release studies showed enhanced dissolution profile from nanosponge formulation (~94% from I11) as compared to the pure drug (~45% Ibuprofen) in 120min. Significant (p<0.05) extent of pain inhibition and anti-inflammatory activity was observed for nanosponge formulation when compared with the pure drug. CD based carbonate nanosponges with better solubility, enhanced release profile, improved analgesic and anti-inflammatory activity were successfully formulated for ibuprofen.

Abstract
This study aimed to fabricate and characterize polymeric microneedle patches for rapid and non-invasive administration of enoxaparin across skin layers. The patches comprising of PVA, sorbitol and enoxaparin sodium were prepared by employing micromolding technique. Formulated patches were characterized physicochemically by folding endurance, dimensional analysis and swelling study, morphologically by optical and scanning electron microscopy and thermally by thermogravimetric analysis. Moreover, performance efficiency of prepared polymeric device was analyzed by in-vitro drug release study and piercing ability. Prepared patches showed appropriate dimensions and folding endurance (i.e., ~1100) indicating satisfactory integrity of polymeric device. Patches exhibited appropriately distanced needles with pointed tips in optical and scanning electron microscopy analysis. Thermogravimetric analysis proved thermal stability of formulation ingredients and prepared patches. Swelling percentage was >110 % suggesting that prepared formulation would allow penetration of physiological fluids in its polymeric network. Maximum (~89%) drug was released within ~2 hours during in-vitro release study. In-vitro piercing ability experiments suggested that prepared patches successfully breached skin barrier stratum corneum. It is concluded that prepared microneedle device can serve as a potential alternative of currently employed invasive parenteral route for rapid and efficient administration of enoxaparin sodium in the systemic circulation.

Abstract
Hepatic stellate cells (HSCs) are crucial for liver injury repair and cirrhosis. However, the mechanism of chemotactic recruitment of HSCs into injury loci is still largely unknown. Here, we demonstrate that serum amyloid A1 (SAA1) acts as a chemokine recruiting HSCs toward injury loci signaling via TLR2, a finding proven by gene manipulation studies in cell and mice models. The mechanistic investigations revealed that SAA1/TLR2 axis stimulates the Rac GTPases through PI3K-dependent pathways and induces phosphorylation of MLC (pSer19). Genetic deletion of TLR2 and pharmacological inhibition of PI3K diminished the phosphorylation of MLCpSer19 and migration of HSCs. In brief, SAA1 serves as a hepatic endogenous chemokine for the TLR2 receptor on HSCs, thereby initiating PI3K-dependent signaling and its effector, Rac GTPases, which consequently regulates actin filament remodeling and cell directional migration. Our findings provide novel targets for anti-fibrosis drug development. SAA1 serves as a chemokine to guide migration of HSCs toward injury locus TLR2 acts as a functional receptor for SAA1 in HSCs SAA1/TLR2 axis-mediated migration of HSCs operates through PI3K/Rac1 signaling SAA1/TLR2 axis provides a link for the cross talk between hepatocytes and HSCs

Abstract
OBJECTIVE The present study was aimed to prepare and characterize new cocrystals of lornoxicam (LORX), a BCS class II drug employing 1,3-dimethyl urea (DMU) as a coformer to improve physicochemical, pharmaceutical, and pharmacokinetic performance. METHODS A screening study was conducted by employing three techniques viz. neat grinding, liquid-assisted grinding (LAG), and solvent evaporation (SE) using different drug-coformer molar ratios (1:1, 1:2, and 1:3). Samples were characterized by DSC, PXRD, ATR-FTIR, SEM, intrinsic dissolution rate (IDR) studies, compressional studies, and pharmacokinetic studies. In vitro dissolution and stability studies (25 °C/60%RH and 40 °C/75%RH for three months) were carried out for cocrystal tablets. RESULTS LAG and SE were found successful in ratio 1:3 and IDR showed approximately 28- and 19-fold increase, respectively in 0.1 N HCl (pH 1.2) and buffer (pH 7.4) as compared to pure LORX. The cocrystal exhibited good tabletability and was ∼2.5 times that of LORX at 6000 Psi. Dissolution profiles of tablets of cocrystal increased (56% and 100% at pH 1.2 and 7.4, respectively in contrast to those of physical mixture (PhyMix) (∼35% and ∼10%) and pure LORX (∼17% and ∼7%) within 60 min. The Cmax and AUC0-∞ for the selected cocrystal were significantly increased (p < 0.05) which was 2.4 and 2.5 times, respectively, that of LORX in a single dose oral pharmacokinetic study executed in rabbits. Tablets of cocrystal were found stable at both conditions. CONCLUSION The study indicates that cocrystallization with DMU can concomitantly improve tabletability, dissolution rate, and in vivo performance of dissolution limited drug LORX.

Abstract
Poor physicomechanical properties and limited aqueous solubility restrict the bioavailability of aceclofenac when given orally. To improve its above properties, aceclofenac (ACE) was cocrystallized with dimethyl urea (DMU) in 1:2 molar ratio by dry and solvent assisted grinding. The cocrystals were characterized by ATR-FTIR, DSC, and PXRD, and their surface morphology was studied by SEM. There was enhancement in intrinsic dissolution rate (IDR) (~eight- and ~fivefold in cocrystals prepared by solvent assisted grinding (SAG) and solid state grinding (SSG), respectively, in 0.1 N HCl, pH 1.2) and similarly (~3.42-fold and ~1.20-fold in phosphate buffer, pH 7.4) as compared to pure drug. Additionally, mechanical properties were assessed by tabletability curves. The tensile strength of ACE was < 1 MPa in contrast to the cocrystal tensile strength (3.5 MPa) which was ~1.98 times higher at 6000 psi. The tablet formulation of cocrystal by direct compression displayed enhanced dissolution profile (~36% in 0.1 N HCl, pH 1.2, and ~100% in phosphate buffer, pH 7.4) in comparison to physical mixture (~ 30% and ~ 80%) and ACE (~18% and ~50%) after 60 min, respectively. Stability studies of cocrystal tablets for 3 months indicated a stable formulation. Pharmacokinetic studies were performed by using rabbit model. The AUC0-∞ (37.87±1.3 μgh/ml) and Cmax (6.94±2.94 μg/ml) of the selected cocrystal C1 prepared by SAG were significantly enhanced (p < 0.05) and were ~3.43 and ~1.63-fold higher than that of ACE. In conclusion, new cocrystal of ACE-DMU was successfully prepared with improved tabletability, in vitro and in vivo properties.

Abstract
Hypertensive crisis (HC) is an emergency health condition which requires an effective management strategy. Over the years, various researchers have developed captopril based fast-dissolving formulations to manage HC; however, primarily, the question of personalisation remains unaddressed. Moreover, commercially these formulations are available as in fixed-dose combinations or strengths, so the titration of dose according to patient's prerequisite is challenging to achieve. The recent emergence of 3D printing technologies has given pharmaceutical scientists a way forward to develop personalised medicines keeping in view patients individual needs. The current project, therefore, is aimed at addressing the limitations as mentioned above by developing fast-dissolving captopril tablets using 3D printing approach. Captopril unloaded (F1) and loaded (F2-F4) filaments were successfully produced with an acceptable drug loading and mechanical properties. Various captopril formulations (F2-F4) were successfully printed using fused deposition modelling technique. The results revealed that the formulations (F2 and F3) containing superdisintegrant had a faster extent of dissolution and in-vivo findings were endorsing these results. The present study has successfully exhibited the utilisation of additive manufacturing approach to mend the gap of personalisation and manufacturing fast-dissolving captopril 3D printed tablets. The procedure adopted in the present study may be used for the development of fused deposition modelling (FDM) based fast-dissolving 3D printed tablets.

Abstract
Purpose: To investigate the efficiency of different solubilizing agents in improving solubility as well as dissolution rate of ebastine (a BCS class II drug) by incorporating prepared solid dispersion into fast disintegrating tablets.Method: The solubility of ebastine was determined in distilled water, lipids and solubilizing agents. Subsequently, the binary solid dispersions were prepared by kneading method using varying weight ratios of ebastine and solubilizing agents. The solid dispersions were then incorporated into fast disintegrating tablets (SD-FDT). Central composite rotatable design (CCD) was used to determine the impact of super disintegrating agents on disintegration time and friability of tablets. The solubility and dissolution rate of developed SD-FDT were compared with a marketed brand. The solid dispersion particles were characterized by Fourier-transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC), powder x-ray diffraction (P-XRD) and scanning electron microscopy (SEM).Results: The saturated solubility of pure ebastine in water was 0.002 ± 0.041 mg/ml while the aqueous solubility of EBT/poloxamer solid dispersion SET3 (P) was 0.018 ± 2.510 mg/ml; on the other hand, EBT/soluplus solid dispersion SET1(S) has an aqueous solubility of 0.242 ± 1.390 mg/ml. Within 30 min, drug release was 14.00 ± 1.77, 78.00 ± 2.31 and 98.70 ± 2.54 % from pure EBT, SET3 (P) and SET1(S), respectively.Conclusion: The solubility and dissolution rate of ebastine has been successfully enhanced by incorporating its solid dispersion in fast-disintegrating tablets (SD-FDT).

Abstract
OBJECTIVES The aim of this study was to prepare orally disintegrating, slow release tablets of naproxen sodium for prompt onset and sustained action required in many types of acute pain. MATERIALS AND METHODS Tablet formulations containing varying concentrations of croscarmellose sodium (a superdisintegrant) and Soluplus® (as release modifier) were prepared by wet granulation method using a single punch tablet machine. The prepared granules were evaluated for their bulk properties and the tablets were evaluated for hardness, disintegration time, and drug release profiles. RESULTS The results showed that the granules so prepared have good flow and compressional properties. A disintegration time of tablets <30 s was achieved by selecting an optimum concentration of croscarmellose sodium. The drug release from the tablets was sustained for 2 h by incorporating a suitable amount of Soluplus®. CONCLUSION This study examined the use of Soluplus® (a novel solubilizer) for the first time as a release modifier of API from tablets.

Abstract
BACKGROUND This study aimed to determine the impact of preoperative exposure to intravenous contrast for CT and the risk of developing postoperative acute kidney injury (AKI) in patients undergoing major gastrointestinal surgery. METHODS This prospective, multicentre cohort study included adults undergoing gastrointestinal resection, stoma reversal or liver resection. Both elective and emergency procedures were included. Preoperative exposure to intravenous contrast was defined as exposure to contrast administered for the purposes of CT up to 7 days before surgery. The primary endpoint was the rate of AKI within 7 days. Propensity score-matched models were adjusted for patient, disease and operative variables. In a sensitivity analysis, a propensity score-matched model explored the association between preoperative exposure to contrast and AKI in the first 48 h after surgery. RESULTS A total of 5378 patients were included across 173 centres. Overall, 1249 patients (23·2 per cent) received intravenous contrast. The overall rate of AKI within 7 days of surgery was 13·4 per cent (718 of 5378). In the propensity score-matched model, preoperative exposure to contrast was not associated with AKI within 7 days (odds ratio (OR) 0·95, 95 per cent c.i. 0·73 to 1·21; P = 0·669). The sensitivity analysis showed no association between preoperative contrast administration and AKI within 48 h after operation (OR 1·09, 0·84 to 1·41; P = 0·498). CONCLUSION There was no association between preoperative intravenous contrast administered for CT up to 7 days before surgery and postoperative AKI. Risk of contrast-induced nephropathy should not be used as a reason to avoid contrast-enhanced CT.

Abstract
Energy is a basic need for the fulfillment of human activities, and usage of energy causes a rise in the carbon emission levels. This paper examines the impact of trade openness, urbanization, imports and exports on carbon emission, and energy intensity for 192 countries from higher, upper-middle, lower-middle, and low-income groups. The data are taken from the year 1990 to 2017 and Generalized method of moments (GMM) is applied for the empirical analyses. Results showed that energy use has less impact on carbon emission in high-income and lower-middle-income economies as compared to the other three sub-panels. Likewise, as a whole, urbanization showed inverse association with emission, on the other hand, it showed positive association with energy intensity in the high-income group. Trade openness showed a positive and highly significant influence on emission as well as on energy intensity. Exports and imports exposed different relations with carbon emission and energy intensity. Outcomes of a Granger causality test yielded an indication of varied causality associations between the variables across the income-based sub-panels. The study suggested the need for improvement in technologies and facilities across the countries for the decline of carbon emission and the enhancement of energy intensity.

Abstract
The aim of this study was to fabricate Bacillus Calmette-Guérin (BCG)-loaded microneedle patches using micromould casting technique and compare their efficacy with the injectable counterparts. The microneedle patches were formulated using sodium alginate (10% w/v) and trehalose (20% of polymer). The patches were characterised using optical microscopy, scanning electron microscopy and folding endurance. Serum IgG, TLC, granulocyte count, lymphocyte count and CRP were assessed and results were compared to that of intradermal injections alongside controls. The results showed that polymeric patches had a thickness of 0.8 mm, microneedle projections of 272 ± 12 µm and folding endurance of more than 300. Based on haematological and IgG ELISA assays, microneedle-based BCG administration significantly activated the immune cells and induced production of lymphocytes, granulocytes and peptide-specific IgG in immunised rats that were comparable to injectable counterparts. There was an increase in IgG antibodies from 3 g/L to 5.98 g/L and an increase in leucocytes from 2.6 × 109/L to 18.45 × 109/L. There was also an increase in granulocytes from 14.4% to 29.15% and lymphocyte count from 58.75% to 85.3%. It was concluded that BCG-coated polymeric microneedle patches are suitable for the transdermal delivery of vaccine without inducing discomfort usually observed with injections.

Abstract
RUNX1/AML1/CBFA2 (runt-related transcription factor 1/acute myeloid leukemia 1 protein/core-binding factor subunit alpha-2), is a transcription factor that plays a critical role in the development of normal hematopoiesis. RUNX1 is also essential for the development of immune cells and sensory neurons. Chromosomal translocations involving the gene have been associated with several types of leukemia. To investigate the role of RUNX1 in human hematopoietic development we generated RUNX1-null human embryonic stem cell reporter line GIBHe008-A by TALEN mediated homologous recombination. This cell line GIBHe008-A was subjected to detailed characterization by standard assays for human pluripotent stem cells. It provides an ideal model to study the role of RUNX1 in the hESC-derived developmental models.

Abstract
PURPOSE: The aim of this study was to evaluate biting force of patients with unilateral mandibular distal extension area treated with two different designs of the removable partial denture (RPD), conventional RPD, and new design of extracoronal castable precision attachment (OT Unilateral attachment).
MATERIALS AND METHODS: This study was conducted on 16 patients with unilateral mandibular distal extension area with the second premolar is the last abutment teeth. The patients were divided into two equal groups, Group I received conventional RPD, which provides cross arch stabilization and a double Aker clasp was fabricated. Group II received new design of extracoronal castable precision attachment (OT Unilateral attachment). Evaluation of biting force by loadstar sensor, patients of both groups were evaluated at the time of prosthesis insertion, 3, 6, and 1 year later. Statistical analysis performing one-way analysis of variance followed by Tukey’s post hoc test to compare between all follow-up periods within each group, comparison between two groups regarding each follow-up period was performed by independent t-test.
RESULTS: Both treatments yielded better after-treatment summary when compared with the baseline; however, better results were obtained and showed a statistically significant increase in Group II (OT unilateral design), especially after 3, 6 months, and 1 year later.
CONCLUSION: From the results of this study, it was concluded that: It is preferable to use the new design of extracoronal castable precision attachment (OT unilateral) being simpler, more comfortable to the patients and give high masticatory efficiency in the form of biting force than conventional RPD.

Abstract
Background Fatty liver is a reversible status, but also an origin stage to develop to other metabolic syndromes, such as diabetes and heart disease that threatens public health worldwide. Ascorbate deficiency is reported to be correlated with increasing risks for metabolic syndromes, but whether ascorbate has a therapeutic effect is unknown. Here, we investigated if ascorbate treatment alone could work on protecting from the development of steatosis and mechanisms beyond. Methods Guinea pigs were fed with a chow diet or a high palm oil diet (HPD) respectively. HPD induced animals were administered different concentrations of ascorbate in different time intervals through water. Besides, hepatocyte-like cells derived from human embryonic stem cells and HepG2 cells were treated with palmitic acid (PA) to induce lipid accumulation for molecular mechanism study. Results We find that ascorbate rescues HPD and PA induced steatosis and insulin tolerance in vivo and in vitro. We demonstrate that ascorbate changes cellular lipid profiles via inhibits lipogenesis, and inhibits the expression of SOCS3 via STAT3, thus enhances insulin signal transduction. Overexpression of SOCS3 abolishes the ascorbate rescue effects on insulin signal and lipid accumulation in hepatic cells. Conclusions Ascorbate ameliorates hepatic steatosis and improves insulin sensitivity through inhibiting lipogenesis and SOCS3.

Abstract
Objective: To gauge the recent breadth of MDR E. coli along with antibiogram of carbapenemase producing (CP) E. coli among children from an institute which receives patients from all over Punjab. Methods: The bacterial strains of E. coli isolated from various specimens of patients were collected from April 2017 to August 2018 and processed using standard biochemical tests and API 20E system (bioMerieux). Phenotypic screening for CP E. coli was done by the modified Hodge test, whereas antibiotic susceptibility testing was done with Kirby-Bauer disc diffusion technique. Results: Total of 6,468 bacterial strains were isolated, out of which 1,552 (24%) were E. coli. Carbapenem resistance was observed in 245 (16%) strains, amongst which 113 (46%) were confirmed to be CP. E. coli isolated from males were higher as compared to females (p<0.05). Majority of the organisms were isolated from blood (37.2%) samples. The hospital discharged about 65% of patients, while 23% left against medical advice. Overall MDR amongst E. coli was 93.26%. Colistin sulphate (15.9%) and nitrofurantoin (16.8%) showed the most efficacy followed by amikacin (15%) and fosfomycin (10.6%). Conclusion: The isolation of high number of MDR E. coli amongst the paediatric patients is worrisome, which could serve as a potential source of horizontal genes transfer to other genera.

Abstract
The present study aimed to explore a new source of montmorillonite and to develop an extraction and purification protocol for its isolation from raw clay samples acquired from the Koh-e-Suleiman mountain range in Pakistan. The process involved the collection of raw clay from the source, identification and quantification of montmorillonite. Granulometric extraction and purification protocols increased the montmorillonite content from 21.8-25.1% in the raw clay to 90.1-93.9% after small-scale extraction and 85.33-89.33% on a larger scale. A techno-economic analysis highlighted the practicality and economic benefits of large-scale extraction for industrial applications. This study highlights the existence of a substantial new source of this valuable clay which is currently used across multiple industries including construction, pottery making, pharmaceuticals, cosmetics and engineering. It is intuitively expected that the large-scale extraction of the material will improve the economic condition of the region by providing employment opportunities to locals and may be a valuable resource for export.

Abstract
The study was aimed to develop a gastro-retentive mucoadhesive sustained release matrix formulation for milnacipran HCl (MCN) by using the design of experiment (DoE). The gastro-retentive swellable mucoadhesive matrix tablets were prepared by modified solvent-based wet granulation through mixing milnacipran (MCN), chitosan low molecular weight (CH-LM), chitosan medium molecular weight (CH-MM), and polycaprolactone (PCL). Optimization of the formulation was carried out via DoE. Formulations were characterized by DSC, FTIR, and in vitro drug release testing. In vitro mucoadhesive studies were performed on rabbit's intestinal mucosa. In vivo drug release studies were performed on dogs. Optimized matrix formulations showed no significant interaction among the polymers and MCN, confirmed by DSC and FTIR, and were characterized as swellable controlled release matrix systems. The optimized formulations MOPT3 and MOPT4 showed significantly improved adhesion time of 12 h on the gastric mucosa. Based on the in vivo analysis, the elimination half-life of MCN was increased that proved the matrix formulation to be sustained release DDS. The Tmax was extended from 2 to 12 ± 1.63 h for MOPT4. Cmax of matrix was reduced to 121.60 ± 9.496 ng/ml as compared to 149.22 ± 9.942 ng/ml of solution. The bioavailability of the matrix formulation was significantly improved as compared to the MCN solution by 272.20 ± 48.11%. The controlled drug release and strong mucoadhesive properties of the gastro-retentive matrix formulations suggested the potential application of the formulations for the extended oral delivery of MCN.
