Abstract
Stercularin is a coumarin, isolated from the ethyl acetate fraction of stem bark and leaves of S. diversifolia. Pharmacologically it is active against cancer, diabetes, and inflammation etc. The molecule is further screened for in vitro pharmacological activities. In addition, a detailed description on its drug likeness and pharmacokinetic profile has been established to further explore its fate as a drug candidate. Stercularin exhibited antiglycation, immunomodulatory, and leishmanicidal activity in three different in vitro models. The IC50 values obtained in these three assays were 80.22 ± 0.46 mg/ml, 12.8 ± 1.6 μg/ml, and 8.32 ± 0.42 μg/ml, respectively. In case of drug likeness evaluation, Stercularin has acceptable physicochemical properties and compliant with major drug likeness descriptors i.e., Lipinski rule, Pfizer rule, GSK rule, and "golden triangle". Accepting Lipinski rule implies the oral drug development of Stercularin. Pharmacokinetically, Stercularin is permeable to Caco-2 and MDCK cell lines. 'Boiled-egg' plot suggest intestinal route of absorption, blood brain barrier nonpermeating, and not affected by p-glycoprotein. Stercularin has high plasma protein binding with low free fraction circulating in the plasma. Stercularin proved to be the substrate and/or inhibitor of CYP 450 system with a moderate half-life and clearance rate to allow flexible dosing regimen. Finally, slight risk of toxicity exists for Stercularin, but not being limiting factors of drug knock out. A nature isolated Stercularin possess pharmacological activities and is predicted to have acceptable pharmacokinetic profile. Further drug development and in vivo studies are desirable for optimization.

Abstract
Hypoplastic asymmetry due to hemifacial microsomia (HFM) often represents the most difficult reconstruction in the craniomaxillofacial clinic. Although autogenous grafts are generally used for temporomandibular joint reconstruction (TMJR), the use of TMJR prostheses is not well established. The aim of this review was to identify, collect and analyse the use of extended TMJR (eTMJR) prostheses in patients with HFM, describing clinical features, surgical procedures and postoperative complications. Online searches of all major databases were performed according to PRISMA guidelines. All studies with HFM patients treated with the eTMJR prostheses were included. Descriptive statistics were used for data analysis. A total of 19 studies, including 08 case studies, 06 case series and 05 retrospective cohort studies, met the inclusion criteria, where a total of 42 HFM patients were reported from 18 countries, mostly from the United States (05; 26%). Fifteen of the 42 cases (~36%) were male. The mean ± SD (range) age of patients in all studies was 19.79 ± 5.81 (9-36) years. The mean ± SD (range) of patient follow-up was 41.30 ± 35.50 (6-136) months. A total of 5 (10.6%) patients were implanted with bilateral eTMJR prostheses. The Pruzansky classification was used in 18 (~89.5%) studies, OMENS classification in 01 (~5%) study, whereas no classification was reported in one study. Only 01 (7.1%) study had documented the eTMJR classification for the prosthesis used. In growing patients with or without a history of failed autogenous tissues, TMJR prostheses may provide a viable alternative. Randomized studies with large cohorts are warranted to validate these preliminary results.

Abstract
BACKGROUND Tracheostomy can be performed as an open surgical procedure, percutaneous, or hybrid and forms an important step in the management of patients infected with coronavirus disease 2019 (COVID-19) requiring weaning from mechanical ventilation. The purpose of this article is to share our experience to performing bedside surgical tracheostomy in COVID-19 patients in a safe and effective manner, whilst minimising the risk of viral transmission, to optimise patient outcomes and reduce risk to healthcare professionals. MATERIAL AND METHODS As recommended by ENT UK, we prospectively established a COVID Airway Team within the ENT department at Birmingham Heartlands Hospital, consisting of four head and neck consultant surgeons to perform either open-bedside, open-theatre or percutaneous tracheostomy in COVID-19 patients. A specific stepwise method for bedside open surgical tracheostomy was based on ENT UK and British Laryngological Society recommendations. RESULTS Thirty patients underwent tracheostomy during the study period (14 bedside-open, 5 open-theatre, 11 percutaneous). Mean duration of mechanical intubation prior to bedside-open tracheostomy was 14.5 days. The average time for open-bedside tracheostomy was 9 minutes compared to 31 minutes for open-theatre. There were no significant tracheostomy related complications with bedside-open tracheostomy. No healthcare professional involved reported acute COVID-19 infection. CONCLUSIONS We describe our effective, safe and swift approach to bedside open tracheostomy during the COVID-19 pandemic. Our experience demonstrated a short mean procedural time, with no tracheostomy-related complications and no reported viral transmission amongst the healthcare members involved.

Abstract
This contribution reports, for the first time, on an entirely green bio-engineering approach for the biosynthesis of single phase crystalline 1-D nano-scaled calcite CaCO3. This was validated using H2O as the universal solvent and natural extract of Hyphaene thebaica fruit as an effective chelating agent. In this room temperature green process, CaCl2 and CO2 are used as the unique source of Ca and CO3 respectively in view of forming nano-scaled CaCO3 with a significant shape anisotropy and an elevated surface to volume ratio. In terms of novelty, and relatively to the reported scientific and patented literature in relation to the fabrication of CaCO3 by green nano-chemistry, the current cost effective room temperature green process can be singled out as per the following specificities: only water as universal solvent is used, No additional base or acid chemicals for pH control, No additional catalyst, No critical or supercritical CO2 usage conditions, Only natural extract of thebaica as a green effective chelating agent through its phytochemicals and proper enzematic compounds, room Temperature processing, atmospheric pressure processing, Nanoscaled size particles, and Nanoparticles with a significant shape anisotropy (1-D like nanoparticles). Beyond and in addition to the validation of the 1-D synthesis aspect, the bio-engineered CaCO3 exhibited a wide-ranging functionalities in terms of highly reflecting pigment, an effective nanofertilizer as well as a potential binder in cement industry.

Abstract
OBJECTIVE Cell phones are carried by 79% of people between 18 and 44 years of age for nearly the entire day. Smartphone users spend an average of three hours/per day on their devices, whereas heavy smartphone users spend 8-10 hours/per day on their devices. Text neck is a dangerous disorder that can accelerate the degeneration of the spine. This study aimed to investigate the efficacy of neck stabilization training vs. Contrology or Pilates training in individuals with Text Neck Syndrome. PATIENTS AND METHODS Participants (n=75) with a history of recurrent neck pain in the previous four months, having moderate pain (at least 4/10 on the numeric pain rating scale, NPRS), and constantly using mobile phones (>4 hours/day) were randomly allocated to one of three groups: a control group (neck isometric training) and two intervention groups (neck stabilization training and Contrology). They were assessed for craniovertebral angle (CVA), NPRS, and neck disability index (NDI) at baseline and at 4 weeks post-intervention. RESULTS There was a significant difference in the CVA, NPRS, and NDI among individuals with Text Neck Syndrome following intervention as compared to the control. Both the neck stabilization and Contrology training increased CVA and reduced neck pain and neck disability in individuals with Text Neck Syndrome. The two intervention groups showed similar effects in all the clinical outcome measures, suggesting almost equivalent effectiveness in the individuals with Text Neck Syndrome. CONCLUSIONS Neck stabilization seems to work better than Contrology training when it comes to increasing the craniovertebral angle, reducing pain intensity, and making it easier for individuals with Text Neck Syndrome to move their necks.

Abstract
Poor pharmacokinetic and safety profiles create significant hurdles in the drug development process. This work focuses on a detailed understanding of drug discovery interplay among physicochemical, pharmacokinetic, toxicity endpoints, and antioxidant properties of oxindole derivatives. DFT compıutations were also performed at B3LYP/6-311G** level to evaluate the physicochemical properties, global reactivity features, and intramolecular interactions. The BOILED-Egg pharmacokinetic model envisaged gastrointestinal absorption, blood-brain barrier penetration, and no interaction with p-glycoprotein for compounds C1 and C2. The physicochemical evaluation revealed that C1 possesses superior drug-like properties fit for oral absorption. Both derivatives were predicted to have high plasma protein binding, efficient distribution, and inhibiting CYP 450 major isoforms but serve as substrates only for a few of them. Both molecules have mild to moderate clearance rates. Out of ten toxicity parameters, only hepatotoxicity was predicted. DFT results implied that the meta position of the -OH group made the possibility of charge transfer greater than -para positioned -OH, due to the ΔNmax (eV) values of molecules C1 and C2 being calculated at 2.596 and 2.477, respectively. Both C1 and C2 exhibited a concentration dependant DPPH and ABTS radical scavenging activity. The chemical structure-physicochemical-pharmacokinetic relationship identified the meta position as the favorite for the electron-withdrawing hydroxyl group. This provides useful insight to medicinal chemists to design 6-chlorooxindole derivatives with an acceptable drug-like and pharmacokinetic property.

Abstract
PURPOSE To analyze the treatment strategies, outcomes and factors impacting these outcomes in extraosseous ewings sarcoma (EOES). MATERIAL AND METHODS A search of the hospital database yielded a total of 109 EOES patients registered in last 10 years out of which 25 patients were excluded from analysis due to incomplete medical records. Demographic and clinical characteristics were reported using descriptive statistics. Overall survival (OS) was taken from the time of diagnosis to death. Patients who were alive or lost to follow up were censored from the survival analysis. A total of 12 clinical and treatment related variables were taken into univariate analysis and those showing significance or a trend towards significance were taken up for multivariate analysis. Further a cluster analysis was done in a quest to find a subgroup which would have a better survival outcome as compared to other clusters. SPSS version 23 was used for statistical analysis. RESULTS Chest wall (n=26), lower extremity (n=22) and paraspinal area (n=14) were the common sites involved. Localised swelling (n=43) was the most common presenting symptom and the median time to presentation was 2 months. Overall survival of the entire cohort at 5 years was 52 percent. Stage at presentation had a significant impact (P value<0.001) on estimated median OS (localised 70 months versus 36 months in metastatic stage). Cluster analysis showed that, patients with localised stage at presentation, good response to chemotherapy, negative resection margin and no adjuvant RT had a median survival of 69 months. CONCLUSION Judicious use of trimodality treatment in EOES yields optimal results and it also adds significantly onto the scarce literature on this subtype of sarcoma.

Abstract
Computational pharmacology and chemistry of drug-like properties along with pharmacokinetic studies have made it more amenable to decide or predict a potential drug candidate. 4-Hydroxyisoleucine is a pharmacologically active natural product with prominent antidiabetic properties. In this study, ADMETLab 2.0 was used to determine its important drug-related properties. 4-Hydroxyisoleucine is compliant with important drug-like physicochemical properties and pharma giants' drug-ability rules like Lipinski's, Pfizer, and GlaxoSmithKline (GSK) rules. Pharmacokinetically, it has been predicted to have satisfactory cell permeability. Blood-brain barrier permeation may add central nervous system (CNS) effects, while a very slight probability of being CYP2C9 substrate exists. None of the well-known toxicities were predicted in silico, being congruent with wet lab results, except for a "very slight risk" for respiratory toxicity predicted. The molecule is non ecotoxic as analyzed with common indicators such as bioconcentration and LC50 for fathead minnow and daphnia magna. The toxicity parameters identified 4-hydroxyisoleucine as non-toxic to androgen receptors, PPAR-γ, mitochondrial membrane receptor, heat shock element, and p53. However, out of seven parameters, not even a single toxicophore was found. The density functional theory (DFT) study provided support to the findings obtained from drug-like property predictions. Hence, it is a very logical approach to proceed further with a detailed pharmacokinetics and drug development process for 4-hydroxyisoleucine.

Abstract
The perceived risk of transmission of aerosolised viral particles from patients to airway practitioners during the COVID-19 pandemic led to the widespread use of aerosol precautions, including personal protective equipment and modifications to anaesthetic technique. The risk of these aerosol precautions on peri-operative airway complications has not been assessed outside of simulation studies. This prospective, national, multicentre cohort study aimed to quantify this risk. Adult patients undergoing general anaesthesia for elective or emergency procedures over a 96-hour period were included. Data collected included use of aerosol precautions by the airway practitioner, airway complications and potential confounding variables. Mixed-effects logistic regression was used to assess the risk of individual aerosol precautions on overall and specific airway complications. Data from 5905 patients from 70 hospital sites were included. The rate of airway complications was 10.0% (95%CI 9.2-10.8%). Use of filtering facepiece class 2 or class 3 respirators was associated with an increased risk of airway complications (odds ratio 1.38, 95%CI 1.04-1.83), predominantly due to an association with difficult facemask ventilation (odds ratio 1.68, 95%CI 1.09-2.61) and desaturation on pulse oximetry (odds ratio 2.39, 95%CI 1.26-4.54). Use of goggles, powered air-purifying respirators, long-sleeved gowns, double gloves and videolaryngoscopy were not associated with any alteration in the risk of airway complications. Overall, the use of filtering facepiece class 2 or class 3 respirators was associated with an increased risk of airway complications, but most aerosol precautions used during the COVID-19 pandemic were not.

Abstract
OBJECTIVE The ensuing ischemia due to the disruption of blood supply to the brain is one of the most common causes of stroke. Evidence suggests a clear association of the ischemic injury with vascular dementia and Alzheimer's disease (AD). In response to the brain ischemia, a cascade reaction starts leading to neuronal damage due to oxidative stress and other inflammatory mediators. A pilot study was done, which showed that following stroke, monomeric-C-reactive protein (mCRP) is expressed in large quantities around the infarcted zone and this CRP is able to induce neurodegeneration and inflammation potentially perpetuating dementia. MATERIALS AND METHODS We examined both patient brain samples and excised mouse brain tissue, previously injected with 1.75 mg/mL mCRP into the CA1 area of the hippocampus through the stereotactic surgical procedures and followed them over a period of over 6 months. The distribution of mCRP was examined through immunohistochemistry (mouse anti-human mCRP-specific antibodies 8C10). RESULTS We observed a novel finding: those micro vessels close to the injection location were strongly stained with mCRP only in the mice that had been injected with mCRP, indicating that this small blood vessel can spread it throughout the brain. CONCLUSIONS mCRP found in the brain after a hemorrhagic stroke promotes damage over a large area via the induction of inflammation and degeneration of perivascular compartments.

Abstract
Anterior cruciate ligament (ACL) is the most frequently injured ligament of the knee. It can be repaired and reconstructed by open and endoscopic method, the gold standard is, however, endoscopic reconstruction. It is usually reconstructed using bone patellar tendon bone (BPTB) or Hamstring autograft. The graft is supported using endobutton at the femoral end while bioabsorbable interference screw at the tibial end. This study aimed to determine how a certain fixation procedure for quadrupled hamstring autografts worked out. This prospective observational study duration period was 1 year in which 40 patients with ACL injury were treated with arthroscopic reconstruction using hamstring autograft from January 2020 to December 2020 with 6 months follow up after surgery. On the femoral side, an endobutton was used to secure the graft, while the tibial end was secured using a bioabsorbable screw. The International Knee Documentation Committee (IKDC) scoring system was used for prospective evaluation. According to subjective IKDC scoring, 20(50.0%) results were very good, 14(35.0%) were good, 4(10.0%) were satisfactory and 2(5.0%) were bad. In 95.0% patients the state of knee joint is very good compared to preoperative state. Of all the 40 patients underwent ACL reconstruction, 38(95.0%) patients are satisfied with the results of the operation.

Abstract
ABSTRACT The present study was conducted to investigate the effect of season and housing system on hematochemical attributes of rabbits in Southern Punjab, Pakistan. Adult healthy rabbits (n=30) were divided into two groups of equal size (n=15). Group I was housed in a modern cage system and group II in traditional colony system for a period of one year. Blood samples of rabbits from both groups were collected in the summer and the winter seasons and analyzed for various hematochemical attributes. Hematochemical attributes including red blood cell (RBC) count, hematocrit (HCT), mean corpuscular volume (MCV), total white blood cell (WBC) count, mixed cells (MID), granulocytes (GRA), glucose and alanine aminotransferase (ALT) were lowered significantly (P<0.05) in the summer in relation to the winter, while mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), creatinine, and cholesterol level were significantly (P<0.05) higher during the summer season. Biochemical attributes as cholesterol, triglycerides and globulin were significantly (P<0.05) lower in the caged rabbits. In conclusion, the summer season caused a significant decrease in most of the hematochemical attributes whereas housing system did not affect most of the hematochemical attributes of the rabbits under the climatic conditions of Southern Punjab, Pakistan.

Abstract
Although photocatalytic technology has emerged as an effective means of alleviating the projected future fuel crisis by converting sunlight directly into chemical energy, no visible-light-driven, low-cost, and highly stable photocatalyst has been developed to date. Due to considerably higher interfacial contact with numerous reactive sites, effective charge transmission and separation ability, and strong redox potentials, the focus has now shifted to 2D/2D heterojunction systems, which have exhibited effective photocatalytic performance. The fundamentals of 2D/2D photocatalysis for different applications and the classification of 2D/2D materials are first explained in this paper, followed by strategies to improve the photocatalytic performance of various 2D/2D heterojunction systems. Following that, current breakthroughs in 2D/2D metal-based and metal-free heterojunction photocatalysts, as well as their applications for H2 evolution via water splitting, CO2 reduction, and N2 fixation, are discussed. Finally, a brief overview of current constraints and predicted results for 2D/2D heterojunction systems is also presented. This paper lays out a strategy for developing efficient 2D/2D heterojunction photocatalysts and sophisticated technology for solar fuel applications in order to address the energy issue.

Abstract
The FDA granted expedited approval for Johnson and Johnson's Bedaquiline to treat pulmonary multidrug resistant tuberculosis on 28 December 2012 which is more common in China, Russian Federation and India. Bedaquiline is the first anti-tubercular drug approved by the FDA in the last 40 years, and it has become a cynosure in the circles of synthetic chemists researching new anti-tubercular drugs. Bedaquiline's highly lipophilic nature raises major concerns like suppression of the hERG gene, hepatotoxicity, and phospholipidosis despite its potential antitubercular profile. To address these toxicity concerns, in the present work, we have employed the structural optimization of Bedaquiline using the ADMETopt web server, which optimizes lead with scaffold hopping and ADMET screening. The ADMETopt web server yielded the 476 structures through optimization of three sites in Bedaquiline. Further, we have validated the optimized structures for their activity by performing molecular docking and molecular dynamics (MD) simulations against the mycobacterial ATP synthase enzyme and density functional theory (DFT) study further provides insight into the reactivity of the compounds. After screening and analysis, compound #449 was observed to be the most promising mycobacterial ATP synthase inhibitor with minimal cardiotoxicity, hepatotoxicity and phospholipidosis.

Abstract
BACKGROUND With growing global prevalence, cancer is a major cause of disease-related deaths. The understanding of the fundamental tumor pathology has contributed to the development of agents targeting oncogenic signaling pathways. Although these agents have increased survival for defined cancers, the therapeutic choices are still limited due to the development of drug resistance. CRISPR/Cas9 is a powerful new technology in cancer therapy by facilitating the identification of novel treatment targets and development of cell-based treatment strategies. PURPOSE We focused on applications of the CRISPR/Cas9 system in cancer therapy and discuss nanoscale delivery of cytotoxic phytochemical targeting the CRISPR/Cas9 system. RESULTS Genome engineering has been significantly accelerated by the advancement of the CRISPR/Cas9 technique. Phytochemicals play a key role in treating cancer by targeting various mechanisms and pathways. CONCLUSIONS The use of CRISPR/Cas9 for nanoscale delivery of phytochemicals opens new avenues in cancer therapy. One of the main obstacles in the clinical application of CRISPR/Cas9 is safe and efficient delivery. As viral delivery methods have certain drawbacks, there is an urgent need to develop non-viral delivery systems for therapeutic applications.

Abstract
In many real-world problems, one may encounter uncertainty in the input data. The fuzzy set theory fits well to handle such situations. However, it is not always possible to determine with full satisfaction the membership and non-membership degrees associated with an element of the fuzzy set. The intuitionistic fuzzy sets play a key role in dealing with the hesitation factor along-with the uncertainty involved in the problem and hence, provides more flexibility in the decision-making process. In this article, we introduce a new ordering on the set of intuitionistic fuzzy numbers and propose a simple approach for solving the fully intuitionistic fuzzy linear programming problems with mixed constraints and unrestricted variables where the parameters and decision variables of the problem are represented by intuitionistic fuzzy numbers. The proposed method converts the problem into a crisp non-linear programming problem and further finds the intuitionistic fuzzy optimal solution to the problem. Some of the key significance of the proposed study are also pointed out along-with the limitations of the existing studies. The approach is illustrated step-by-step with the help of a numerical example and further, a production planning problem is also demonstrated to show the applicability of the study in practical situations. Finally, the efficiency of the proposed algorithm is analyzed with the existing studies based on various computational parameters.

Abstract
The conventionally synthesized nano-ferrite materials do not possess bulk properties, generally required for their use in mainstream industry. To make ferrite nanoparticles clinically applicable materials, it is important to have good control over morphology and optical properties of these materials. In this study, low-pressure microwave plasma was used to tailor the structural properties and surface chemistry of manganese ferrite nanoparticles. A facile sol-gel method was used to prepare cubic spinal structures of manganese ferrite nanoparticles. These nanoparticles were exposed to oxygen plasma sustained with a microwave source for improving their magnetic and photocatalytic activities. The techniques like XRD, SEM, PL, UV-Vis DRS, transient photocurrent response and EIS were used to characterize the samples. The plasma treated nanoparticles were used to degraded methyl blue (MB) dye in the solution. The photocatalytic activity showed 85% degradation of MB after 100 min of exposure of visible light. The second part of the paper studied the magnetic properties of the nanoparticles. The saturation magnetization decreased from 0.78 emu/g to 0.68 emu/g after plasma treatment of nanoparticles.

Abstract
Haematoma after thyroid surgery can lead to airway obstruction and death. We therefore developed guidelines to improve the safety of peri‐operative care of patients undergoing thyroid surgery. We conducted a systematic review to inform recommendations, with expert consensus used in the absence of high‐quality evidence, and a Delphi study was used to ratify recommendations. We highlight the importance of multidisciplinary team management and make recommendations in key areas including: monitoring; recognition; post‐thyroid surgery emergency box; management of suspected haematoma following thyroid surgery; cognitive aids; post‐haematoma evacuation care; day‐case thyroid surgery; training; consent and pre‐operative communication; postoperative communication; and institutional policies. The guidelines support a multidisciplinary approach to the management of suspected haematoma following thyroid surgery through oxygenation and evaluation; haematoma evacuation; and tracheal intubation. They have been produced with materials to support implementation. While these guidelines are specific to thyroid surgery, the principles may apply to other forms of neck surgery. These guidelines and recommendations provided are the first in this area and it is hoped they will support multidisciplinary team working, improving care and outcomes for patients having thyroid surgery.

Abstract
INTRODUCTION The COVID-19 pandemic has demanded radical changes in service delivery. Our centre adopted the use of outpatient telemedicine to reduce close-contact interactions between patients and staff. We hypothesised that incidental gains may be associated with this. We evaluated financial, practical and environmental implications of substituting virtual clinics (VCs) for in-person urology outpatient appointments. METHODS VCs were studied over a 3-month period. Based on patient-reported 'usual mode of transport' to the hospital, travel distance, time, petrol and parking costs, and the carbon emissions avoided by virtue of remote consultations were calculated. The underlying symptom/diagnosis and the 'effectiveness' of the VC were evaluated. RESULTS Of 1,016 scheduled consultations, 736 (72.44%) were conducted by VCs over the study period. VCs resulted in an agreed treatment plan in 98.4% of a representative patient sample. The use of VCs was associated with an overall travel distance saving for patients of 31,038 miles (49,951km) over 3 months, with an average round-trip journey of 93.8 miles (151km) avoided for each rural-dwelling patient and an average financial saving of £25.91 (€28.70) per rural-dwelling car traveller. An estimated 1,257.8 hours of patient time were saved by avoidance of travel and clinic waiting times. Based on car-travelling patients alone, a 6.07-tonne reduction in carbon emissions was achieved with the use of VCs. CONCLUSIONS In appropriate clinical circumstances, VCs appear to provide efficiency across a number of domains. Future healthcare may involve offering outpatients the option of telemedicine as an alternative to physical attendance.

Abstract
AbstractOsteopetrosis is a rare metabolic disease. Dental abnormalities may be attributed to the pathological changes in osteopetrosis. Patients with disease seem to be especially susceptible to osteomyelitis of mandible. A 9 yrs old girl presented with complaints of jaw swelling on left side with multiple discharging sinuses since last seven months. The radiograph of left mandible (oblique lateral view) showed periodontal involvement of associated molars with loss of lamina dura with small sequestrum with irregularity and erosions of the mandibular cortical margins. The patient was diagnosed as a case of osteopetrosis with superadded mandibular osteomyelitis.

Abstract
A research was conducted to evaluate the impact of various nitrogen and phosphorus levels along with beneficial microbes to enhance canola productivity. The research was carried out at Agronomy Research Farm, The University of Agriculture Peshawar in winter 2016-2017. The experiment was conducted in randomized complete block factorial design. The study was comprised of three factors including nitrogen (60, 120 and 180 kg ha-1), phosphorous (70, 100 and 130 kg ha-1) and beneficial microbes (with and without BM). A control treatment with no N, P and BM was also kept for comparison. Application of beneficial microbes significantly increased pods plant, seed pod, seed filling duration, 1000 seed weight, biological yield and seed yield as compared to control plots. Nitrogen applied at the rate of 180 kg ha-1 increased pods plant-1, seed pod, seed filling duration, seed weight, biological yield and seed yield. Maximum pods plant-1, seed pod, early seed filling, heavier seed weight, biological yield, seed yield, and harvest index were observed in plots treated with 130 kg.ha-1 phosphorous. As comparison, the combine treated plots have more pods plant-1, seeds pod-1, seed filling duration, heaviest seeds, biological yield, seed yield and harvest index as compared to control plots. It is concluded that application of beneficial microbes with N and P at the rate of 180 kg ha-1 and 130 kg ha-1, respectively, increased yield and its attributes for canola.

Abstract
People in Bangladesh are traditionally used to consume mainly black tea. However, some
tea manufacturing companies are now producing green tea, though in a small scale. To
create new knowledge as well as awareness about the consumption of green tea, the
present study was carried out to compare the black and green tea available in Bangladesh
based on their bioactive compounds and antioxidant activity. A total of eight brands of
black tea and two brands of green tea were bought from the supermarkets. Total phenolics,
total tannin, total flavonoids, and caffeine content were measured as bioactive compounds,
and antioxidant activity was evaluated by using two different methods such as DPPH (1,1-
diphenyl-2-picrylhydrazyl) radical-scavenging activity and ABTS+ radical scavenging
activity of methanol extracts of black and green tea. Every bioactive compound in black
and green tea was found to be significantly different (P < 0.05). The total phenolic
content, on average, was measured at 242.46 mg GAE/g dry extract and 763.41 mg GAE/
g dry extract in black and green tea, respectively. Black tea contained 6.47 mg TAE/g dry
extract tannin, whereas green tea had much more tannin content, 14.51 mg TAE/g dry
extract, which is more than double in amount. On the other hand, the total flavonoid
content was almost double in black tea (61.82 mg QE/g dry extract) compared to green tea
(31.85 mg QE/g dry extract). Antioxidant activities were determined at different
concentrations of tea samples. At every concentration, green tea presented higher ABTS+
and DPPH radical scavenging activity than black tea. The highest percentage of inhibition
was observed at 20 ppm both in black and green tea, finding 98.50 % and 99.07 %
inhibition, respectively. Overall, significantly (P < 0.05) higher amount of phenolic
compounds as well as antioxidant activity were observed in green tea.

Abstract
In the maize-soybean intercropping system, shade is the major chronic restraint that affects normal growth of soybean. Different spatial patterns of this system affect the microclimate of soybean through shading from maize plants. However, the negative impacts of shading stress can be mitigated by providing optimal ratios of different fertilizers. Therefore, to test this hypothesis, soybean plants were grown under different light conditions (normal light or shade) to evaluate the response to varying NH4 + /NO3 - ratios. Seeds of soybean (Glycine max L. cv. Nan-99-6) were grown in nutrient solution with a total concentration of 5 mM N using different NH4 + /NO3 - ratios (T0 = 0:0, T1 = 0:100, T2 = 25:75, T3 = 50:50 and T4 = 75:25) for 40 days in a greenhouse at PPFD 320.95 μmol m-2 s-1 (low light) or 967.53 μmol m-2 s-1 (normal light). Under low light, growth and photosynthesis of soybean seedlings significantly decreased as compared to normal light conditions. However, the optimal ratios of NH4 + / NO3 - improved growth and photosynthesis of soybean seedlings under both light conditions. Our results indicated that soybean seedlings supplied with optimal NH4 + /NO3 - ratios (25:75 and 50:50) have maximum biomass yield, chlorophyll pigments, leaf gas exchange, photochemical activity and root growth as compared to low and high NH4 + /NO3 - ratios (T1 and T4 ). High ratios of NH4 + /NO3 - (T4 ) resulted in reduced plant growth due to nutrient accumulation in plant tissues; therefore, we suggest that optimal ratios of NH4 + /NO3 - (T2 and T3 ) can enhance the shade tolerance of soybean seedlings.

Abstract
Lodging in maize results in grain yield reduction. This experiment investigated the effects of different application rates of the growth retardant, uniconazole (UCZ), and nitrogen (N) on medium and high maize population densities on lodging resistance and yield. UCZ was applied to maize seeds at concentrations of 0 (U0 ) and 25 (U25 ) mg kg-1 , and three different N application rates, 0 (N0 ), 150 (N150 ) and 225 (N225 ) kg ha-1 , at plant densities of 75,000 (D1 ) and 105,000 plants ha-1 (D2 ). UCZ application, different N rates and plant population density affected the lodging resistance and yield attributes of maize. The diameter, plumpness, cortex penetration and bending strengths of the internodes were enhanced with UCZ and N application at medium and high plant density, where maximum values were obtained with U25 N150 D1 . Internode length increased in the high-density population and higher N rate, whereas UCZ reduced internode length, where maximum internode length was obtained with U0 N225 D2 . Plant height, centre of gravity height, ear and height above ear-bearing node were higher with the high N rate, while UCZ reduced it significantly. UCZ, N rate and plant density enhanced lignin accumulation in the third internode and ear-bearing internode, where maximum values were obtained with U25 N150 D1 . Yield and yield attributes were also improved by UCZ, N rate and population density. Treatment with U25 N150 D2 significantly improved grain yield of maize compared with the other treatments.

Abstract
In this paper, we introduce fuzzy bipolar soft semiprimality in the structure of ordered semigroups and investigate some properties of the concept. Moreover, ordered semigroups and their some classes are characterized by means of fuzzy bipolar soft semiprimality. Finally, the Cartesian product of fuzzy bipolar soft semiprime (resp., prime) ideals over ordered semigroups is examined. Some of the ideas are supported by apt examples.
