Microscopic investigation and pharmacognostic evaluation of leaves of Anemone rupicola Camb.

There is almost no scientific literature available on the phytochemistry and pharmacognosy of this plant so the basic aim of the study is to analyze pharmacognostic features of dried leaves of Anemone rupicola Camb. Morphology was studied by using the features like margins, shape, length, width, surface and so forth. For anatomical examination leaves were preserved in formalin acetic alcohol (FAA) and cutting the thin section of leaves and petiole with razor blade. Macroscopic characters of powdered drug were evaluated through organoleptic method. Qualitative phytochemical analysis was done by adopting the standard procedures. The antimicrobial activity of methanolic extract of Anemone rupicola Camb. was performed by Agar well diffusion method. The powder microscopic study showed epidermal cells, trichomes, various type of tracheids, pitted vessels, and sclerenchymatous fibers. Transverse cutting of leaves and petiole revealed the presence of different cells such as epidermis, palisade parenchyma, spongy parenchyma cells, aerenchyma, collenchyma, trichomes, and vascular bundles. The investigation of phytochemicals in distilled water, methanol and in ethanol solvent indicated the presence of various secondary compounds such as phenols, saponins, glycosides, alkaloids, tannins, cardiac glycosides, terpenoids, coumarins, and flavonoids. The methanolic extract of Anemone rupicola Camb. has potential as an antimicrobial agent. However, further studies are needed to confirm its efficacy and safety. This study can be used as powerful tool for the identification and authentication of this plant. For the purity and quality control these results will be helpful tool. This will also shed light into new areas where researchers can intervene in developing new drugs for future use.

Dynamics of the time-fractional reaction-diffusion coupled equations in biological and chemical processes.

This paper aims to demonstrate a numerical strategy via finite difference formulations for time fractional reaction-diffusion models which are ubiquitous in chemical and biological phenomena. The time-fractional derivative is considered in the Caputo sense for both linear and nonlinear problems. First, the Caputo derivative is replaced with a quadrature formula, then an implicit method is used for the remaining part. In the linear case, the proposed strategy reduces the time fractional models into linear simultaneous equations. In nonlinear cases, Quasilinearization is utilized to tackle the nonlinear parts. With this strategy, solutions of the fractional system transform into linear algebraic systems which are easy to solve. Next, the Von Neumann method is implemented to examine the stability of the scheme which discloses that the scheme is unconditionally stable. Further, the applicability of the presented scheme is tested with different linear and nonlinear models which include the one dimensional Schnakenberg and Gray-Scott models, and one and two dimensional Brusselator models. To analyze the accuracy of the present technique two norms namely, L ∞ and L 2 , and relative error are addressed. Moreover, the obtained outcomes are shown tabulated and graphically which identifies that the scheme properly works for the time fractional reaction-diffusion systems.

Homozygous Mutations in GDAP1 and MFN2 Genes Resulted in Autosomal Recessive Forms of Charcot-Marie-Tooth Disease in Consanguineous Pakistani Families.

Charcot-Marie-Tooth disease (CMT) is a heritable neurodegenerative disease of peripheral nervous system diseases in which more than 100 genes and their mutations are associated. Two consanguineous families Dera Ghazi Khan (PAK-CMT1-DG KHAN) and Layyah (PAK-CMT2-LAYYAH) with multiple CMT-affected subjects were enrolled from Punjab province in Pakistan. Basic epidemiological data were collected for the subjects. Nerve conduction study (NCS) and electromyography (EMG) were performed for the patients. Whole-exome sequencing (WES) followed by Sanger sequencing was applied to report the genetic basic of CMT. The NCS findings revealed that sensory and motor nerve conduction velocities for both families were <38 m/s. EMG presented denervation, neuropathic motor unit potential, and reduced interference pattern of peripheral nerves. WES identified that a novel nonsense mutation (c. 226 G>T) in GADP1 gene and a previously known missense mutation in MFN2 gene (c. 334 G>A) cause CMT4A (Charcot-Marie-Tooth disease type 4A) in the PAK-CMT1-DG KHAN family and CMT2A (Charcot-Marie-Tooth disease type 2A) in the PAK-CMT2-LAYYAH family, respectively. Mutations followed Mendelian pattern with autosomal recessive mode of inheritance. Multiple sequence alignment by Clustal Omega indicated that mutation-containing domain in both genes is highly conserved, and in situ analysis revealed that both mutations are likely to be pathogenic. We reported that a novel nonsense mutation and a previously known missense mutation in GAPD1 gene and MFN2 gene, respectively, cause CMT in consanguineous Pakistani families.

Epidemiology Of Male Urethral Strictures In Pakistan.

Urethral stricture disease is relatively common in Pakistan, constituting 4-5% of the urological workload. Despite the high prevalence, little is known about its epidemiology in the country. The current narrative review comprised search on PubMed, Pak MediNet and Google Scholar databases for studies done in Pakistan and published between January 1, 2000, and December 31, 2021. The search yielded 30 local publications on stricture urethra. Demographic data as well as causes and management pattern of male urethral stricture were noted and analysed. There were 5,021 patients, with 3850 (76.6%) being from the province of Sindh. The disease had the greatest impact on younger patients aged up to 40 years (n=1572), while after the age of 60 years, 248 (9%) patients had the disease. The common cause was trauma due to road traffic accidents in both anterior and posterior strictures compared to idiopathic cause reported in the West. Infection 170 (6.9%) and Lichen sclerosis 123(4.5%) as a cause was found to decline in our region. A clinic-based regular urethral dilatation was still in practice at some centres to manage such cases. Vast majority of stricture patients were being treated by endoscopic procedures, and only 1154 (23%) cases underwent urethroplasty.

Traditional uses, phytochemistry, pharmacology, and toxicology of the genus Artemisia L. (Asteraceae): A high-value medicinal plant.

Biologically active secondary metabolites, essential oils, and volatile compounds derived from medicinal and aromatic plants play a crucial role in promoting human health. Within the large family Asteraceae, the genus Artemisia consists of approximately 500 species. Artemisia species have a rich history in traditional medicine worldwide, offering remedies for a wide range of ailments, such as malaria, jaundice, toothache, gastrointestinal problems, wounds, inflammatory diseases, diarrhoea, menstrual pains, skin disorders, headache, and intestinal parasites. The therapeutic potential of Artemisia species is derived from a multitude of phytoconstituents, including terpenoids, phenols, flavonoids, coumarins, sesquiterpene lactones, lignans, and alkaloids that serve as active pharmaceutical ingredients (API). The remarkable antimalarial, antimicrobial, anthelmintic, antidiabetic, anti-inflammatory, anticancer, antispasmodic, antioxidative and insecticidal properties possessed by the species are attributed to these APIs. Interestingly, several commercially utilized pharmaceutical drugs, including arglabin, artemisinin, artemether, artesunate, santonin, and tarralin have also been derived from different Artemisia species. However, despite the vast medicinal potential, only a limited number of Artemisia species have been exploited commercially. Further, the available literature on traditional and pharmacological uses of Artemisia lacks comprehensive reviews. Therefore, there is an urgent need to bridge the existing knowledge gaps and provide a scientific foundation for future Artemisia research endeavours. It is in this context, the present review aims to provide a comprehensive account of the traditional uses, phytochemistry, documented biological properties and toxicity of all the species of Artemisia and offers useful insights for practitioners and researchers into underutilized species and their potential applications. This review aims to stimulate further exploration, experimentation and collaboration to fully realize the therapeutic potential of Artemisia in augmenting human health and well-being.

Evaluation of predictive factors of renal function recovery in renal failure secondary to urinary tract obstruction.

Objective: To determine the factors associated with renal function recovery in individuals with kidney failure due to obstruction in the urinary tract. METHODS: The prospective, descriptive study was conducted July 2020 to August 2021 at the Department of Urology, Sindh Institute of Urology and Transplantation, Karachi, and comprised adult patients of either gender who had renal failure secondary to obstructive urinary tract. Baseline data regarding patients' variables, including age, gender, duration of symptoms (<25 days or >25 days), haemoglobin (<9.85g/dl or >9.85g/dl), serum creatinine and renal cortical thickness (<16.5mm or >16.5 mm), was noted on a proforma. The variables were stratified to assess impact on renal recovery. Data was analysed using SPSS 23. RESULTS: Of the 126 patients, 43(34.13%) were males and 83(65.87%) were females. The overall mean age was 44.13±14.18 years. Renal recovery occurred in 67(78.8%) patients having duration of symptoms ≤25 days, and in 13(31.7%) patients with duration of symptoms >25 days (p<0.001). Renal recovery occurred in 41(58.6%) patients having haemoglobin ≤9.85g/dL and in 39(69.6%) patients having haemoglobin >9.85g/dL (p=0.2). Renal recovery occurred in 26(37.7%) patients with parenchymal thickness ≤16.5mm and in 54(94.7%) patients with renal cortical thickness >16.5mm (p<0.001). Conclusion: Symptom duration ≤25 days, and renal parenchymal thickness >16.5mm were found to be predictive factors of good recovery in renal failure cases secondary to obstructive uropathy.

Vision beyond the Field-of-View: A Collaborative Perception System to Improve Safety of Intelligent Cyber-Physical Systems.

Cyber-physical systems (CPSs) that interact with each other to achieve common goals are known as collaborative CPSs. Collaborative CPSs can achieve complex goals that individual CPSs cannot achieve on their own. One of the examples of collaborative CPSs is the vehicular cyber-physical systems (VCPSs), which integrate computing and physical resources to interact with each other to improve traffic safety, situational awareness, and efficiency. The perception system of individual VCPS has limitations on its coverage and detection accuracy. For example, the autonomous vehicle's sensor cannot detect occluded objects and obstacles beyond its field of view. The VCPS can combine its own data with other collaborative VCPSs to enhance perception, situational awareness, accuracy, and traffic safety. This paper proposes a collaborative perception system to detect occluded objects through the camera sensor's image fusion and stitching technique. The proposed collaborative perception system combines the perception of surrounding autonomous driving systems (ADSs) that extends the detection range beyond the field of view. We also applied logistic chaos map-based encryption in our collaborative perception system in order to avoid the phantom information shared by malicious vehicles and improve safety in collaboration. It can provide the real-time perception of occluded objects, enabling safer control of ADSs. The proposed collaborative perception can detect occluded objects and obstacles beyond the field of view that individual VCPS perception systems cannot detect, improving the safety of ADSs. We investigated the effectiveness of collaborative perception and its contribution toward extended situational awareness on the road in the simulation environment. Our simulation results showed that the average detection rate of proposed perception systems was 45.4% more than the perception system of an individual ADS. The safety analysis showed that the response time was increased up to 1 s, and the average safety distance was increased to 1.2 m when the ADSs were using collaborative perception compared to those scenarios in which the ADSs were not using collaborative perception.

Fabrication of a Double Core-Shell Particle-Based Magnetic Nanocomposite for Effective Adsorption-Controlled Release of Drugs.

There has been very limited work on the control loading and release of the drugs aprepitant and sofosbuvir. These drugs need a significant material for the control of their loading and release phenomenon that can supply the drug at its target site. Magnetic nanoparticles have characteristics that enable them to be applied in biomedical fields and, more specifically, as a drug delivery system when they are incorporated with a biocompatible polymer. The coating with magnetic nanoparticles is performed to increase efficiency and reduce side effects. In this regard, attempts are made to search for suitable materials retaining biocompatibility and magnetic behavior. In the present study, silica-coated iron oxide nanoparticles were incorporated with core-shell particles made of poly(2-acrylamido-2-methylpropane sulfonic acid)@butyl methacrylate to produce a magnetic composite material (MCM-PA@B) through the free radical polymerization method. The as-prepared composite materials were characterized through Fourier-transform infrared (FTIR)spectroscopy, scanning electron microscopy (SEM), X-ray diffraction analysis (XRD), energy-dispersive X-Ray Analysis (EDX), and thermogravimetric analysis (TGA), and were further investigated for the loading and release of the drugs aprepitant and sofosbuvir. The maximum loading capacity of 305.76 mg/g for aprepitant and 307 mg/g for sofosbuvir was obtained at pH 4. Various adsorption kinetic models and isotherms were applied on the loading of both drugs. From all of the results obtained, it was found that MCM-PA@B can retain the drug for more than 24 h and release it slowly, due to which it can be applied for the controlled loading and targeted release of the drugs.

Augmentation Cystoplasty in Adult Patients with Renal Impairment.

Bladder augmentation is beneficial in patients with neurogenic bladder due to spinal cord injury, multiple sclerosis, and tuberculous bladder. This retrospective study was done to determine the outcome of augmentation cystoplasty in adult patients with renal dysfunction. The study was done at the Sindh Institute of Urology and Transplantation (SIUT), Karachi from January 2010 till December 2019. A total of 153 patients underwent augmentation cystoplasty. Among these, 28 patients met the inclusion criteria of adult patients with age >18 years, and renal impairment at the time of the procedure. Exclusion criteria were patients with normal renal functions. Out of 28 patients, 17 (60%) showed improvement in renal functions post-augmentation cystoplasty, while 2 (7.14%) deteriorated and 9 (32.13%) patients showed static function in the same chronic kidney disease stages. Results from this study showed that augmentation cystoplasty is a safe operative procedure even in renal failure patients. It leads to improvement in renal functions in a significant number of patients. Key Words: Adults, Augmentation cystoplasty, Renal failure, Bladder compliance.

SafeSoCPS: A Composite Safety Analysis Approach for System of Cyber-Physical Systems.

The System of Cyber-Physical Systems (SoCPS) comprises several independent Cyber-Physical Systems (CPSs) that interact with each other to achieve a common mission that the individual systems cannot achieve on their own. SoCPS are rapidly gaining attention in various domains, e.g., manufacturing, automotive, avionics, healthcare, transportation, and more. SoCPS are extremely large, complex, and safety-critical. As these systems are safety-critical in nature, it is necessary to provide an adequate safety analysis mechanism for these collaborative SoCPS so that the whole network of these CPSs work safely. This safety mechanism must include composite safety analysis for a network of collaborative CPS as a whole. However, existing safety analysis techniques are not built for analyzing safety for dynamically forming networks of CPS. This paper introduces a composite safety analysis approach called SafeSoCPS to analyze hazards for a network of SoCPS. In SafeSoCPS, we analyze potential hazards for the whole network of CPS and trace the faults among participating systems through a fault propagation graph. We developed a tool called SoCPSTracer to support the SafeSoCPS approach. Human Rescue Robot System-a collaborative system-is taken as a case study to validate our proposed approach. The result shows that the SafeSoCPS approach enables us to identify 18 percent more general faults and 63 percent more interaction-related faults in a network of a SoCPS.

In-Plane Seismic Strengthening of Brick Masonry Using Steel and Plastic Meshes.

Unreinforced masonry structures are vulnerable to seismic loading due to their brittle behavior, and must therefore be strengthened. This paper presents the seismic performance of brick masonry strengthened with steel and plastic meshes. For this purpose, twenty masonry wallets of (600 × 600 × 113 mm) were constructed, keeping the same materials and workmanship. Fifteen of them were reinforced using steel and plastic meshes. These specimens were tested for in-plane static cyclic diagonal tension (shear) behavior. The critical parameters, such as shear stress, strain, failure modes, ductility, energy dissipation, and stiffness degradation were investigated. Compared to reference and plastic-reinforced specimens, the steel-reinforced samples were found to be highly effective. Furthermore, the recommended category of steel increased the shear capacity, energy dissipation, and ductility ratio by 1.3, 14, and 6.3 times, respectively.

Numerical Solutions of Variable Coefficient Higher-Order Partial Differential Equations Arising in Beam Models.

In this work, an efficient and robust numerical scheme is proposed to solve the variable coefficients' fourth-order partial differential equations (FOPDEs) that arise in Euler-Bernoulli beam models. When partial differential equations (PDEs) are of higher order and invoke variable coefficients, then the numerical solution is quite a tedious and challenging problem, which is our main concern in this paper. The current scheme is hybrid in nature in which the second-order finite difference is used for temporal discretization, while spatial derivatives and solutions are approximated via the Haar wavelet. Next, the integration and Haar matrices are used to convert partial differential equations (PDEs) to the system of linear equations, which can be handled easily. Besides this, we derive the theoretical result for stability via the Lax-Richtmyer criterion and verify it computationally. Moreover, we address the computational convergence rate, which is near order two. Several test problems are given to measure the accuracy of the suggested scheme. Computations validate that the present scheme works well for such problems. The calculated results are also compared with the earlier work and the exact solutions. The comparison shows that the outcomes are in good agreement with both the exact solutions and the available results in the literature.

Induction of Semi-Dwarf Trait to a Three Pistil Tall Mutant Through Breeding With Increased Grain Numbers in Wheat.

Multi-ovary wheat (three pistil) is a unique germplasm for the seed production of hybrid wheat. The purpose of the present study was to transfer the multi-ovary trait to semi-dwarf plants to increase the production of grains in wheat crops. Therefore, tall, semi-dwarf, and dwarf plants were crossed with plants with the three-pistil trait. A three-pistil tall plant was used as the female parent, while tall (Synthetic hexaploid), semi-dwarf, and dwarf plants were used as male parents. F1 and F2 progenies with parents were planted in 2015-16 using RCBD. The outcome of the crosses showed that multi-ovary tall plants gave significant difference for all five traits (days to maturity, plant height, number of seeds per spike, grain weight per spike, and grain yield per unit area) in both generations. The greatest number of grains per spike and grain yield per unit area were obtained from the cross of three-pistil tall and dwarf parent (P1/P6) in the F1 and F2 generations. The cross also resulted in a significant reduction in height (96 cm). Further heterosis studies conducted with crosses between three-pistil tall and dwarf parent (P1/P6) showed the greatest heterosis and heterobeltiosis for the number of grains per spike (60.0 and 26.19%, respectively) and grain yield per m2 (27.68 and 2.85%, respectively). In the case of grain weight per spike, the heterosis value was also positive and significant (17.7). Meanwhile, for other traits, their values were negative for heterosis and heterobeltiosis. High numbers of grains and grain weight were found to be associated with positive heterobeltiosis and in turn the grain yield per m2, but plant height and maturity had negative affirmation with heterobeltiosis. Heterosis studies also indicated the dominant gene action for the three-pistil trait. Thus, the study clearly signified that grain yield can be increased by using the multi-ovary genotype with the semi-dwarf height. This new germplasm will be helpful for breeders to increase the production of wheat crops in the southern climate of Pakistan.

Overview of Polyethylene Glycol-based Materials with a Special Focus on Core-Shell Particles for Drug Delivery Application.

Polyethylene glycols (PEG) are water-soluble non-ionic polymeric molecules. PEG and PEG-based materials are used for various important applications, such as solvents, adhesives, adsorbents, drug delivery agents, tissue engineering scaffolds, etc. The coating of nanoparticles with PEG forms core-shell nanoparticles. The PEG-based core-shell nanoparticles are synthesized for the development of high-quality drug delivery systems. In the present review, we first explained the basics and various applications of PEGs and PEG-based composites materials and then concentrated on the PEG-based core-shell nanoparticles for biomedical applications, specifically their use in drug delivery.

Impact of vehicular emissions on anatomical and morphological characteristics of vascular plants: A comparative study.

Abbottabad is a famous tourist destination due to its greenery and location. However, rapid increase in population and unplanned urbanization cause various environmental problems. Among different environmental stress, vehicular emission is the major issue for the survival and sustainability of plant species. This study aimed to investigate the effects of atmospheric pollution (caused by vehicular emission) on the anatomical, biochemical and morphological aspects of plant species present alongside the roads of Abbottabad, Pakistan. The plants were also collected from control sites (away from road-sites) for comparison. The results showed that various morphological characteristics of plant species including petiole length, vein-to-vein difference between leaves and length to breadth ratio of leaves were adversely affected by air pollution. The stomatal index varies in plant species because of variations in the numbers of epidermal cells. The air pollution tolerance index (APTI) of plant leaves from contaminated areas was reported to be higher as compared to control (non-contaminated) areas. Consequently, the findings from this study confirmed that plant species growing alongside of Abbottabad roads has greater tolerance than plant species growing in solitude areas away from road sites (control sites). Among different studied plants, Juglans regia, Morus nigra, Xanthium strumarium, Prunus armenica, Diospterus lotus and Populus ciliata have highest APTI and found to be more suitable for plantation in Abbottabad.

Morpho-palynological investigation of gymnospermal flora from subalpine and alpine zones of northern Pakistan using LM and SEM.

The pollen morphology, with special reference to exine sculpture, of some species of the gymnosperms was assessed for the first time from the subalpine and alpine zones of western Himalayas northern Pakistan. The pollen of all these species is airborne and allergenic, so pollen morphology helps for identification of this allergenic pollen at specific level. Different morpho-palynological characteristics were analyzed including size range of pollen, polar and equatorial diameter ratio, exine ornamentation, sculpturing, exine thickness, pollen type, and shape. For accurate and quick identification of species, taxonomic key was made based on different morpho-palynological characteristics. The quantitative data were processed using SPSS software. Gymnospermal pollen includes inaperturate, rarely 1-colpate observed in (Cupressaceae), hexazonocolpate in (Ephedraceae), vesiculate, bissacate in (Pinaceae), and inaperturate in (Taxaceae). Different pollen shapes observed were prolate (4 spp), sub-spheroidal (7 spp), and oblate (1 spp). Variation was observed in exine sculpturing granular (4 spp), reticulate (1 spp), areolate-punctate (3 spp), and psilate (2 spp). This is based on the analysis of 10 plants belonging to four families of gymnosperms. Distinct pollen shape has emerged as the most diagnostic feature to separate some genera such as spheroidal in (Cupressaceae, Taxaceae), prolate and radiosymmetrical in (Ephedraceae), and bilateral in (Pinaceae). Exine thickness and sculpturing proved to be helpful at generic and specific levels. The results reinforced the significance of gymnospermal pollen morphological features which were used as aid for valuable taxonomic tool in plant systematics.
