Rhodamine B for Probing the Effects of Modifications in Cetrimonium Bromide Counter-anions by Transition Metals on CTAB/Butanol/n-hexane/water Microemulsion.

Dye solubilization in microemulsion based on Cetyltrimethylammonium bromide (CTAB) and its modified forms (counter-anions based upon Zn2+, Cu2+ and Fe3+) is comparatively innovative and not explored in existing literature. Here, surfactant with modified counterions (SMCs) were used to study the effects of metal chlorides (ZnCl2, CuCl2 and FeCl3) modifications on the comparative solubilization of Rhodamine-B (RB) by Cetyltrimethylammonium bromide (CTAB) and its modified forms. The solubility of RB in different microemulsions were studied using UV-Visible spectroscopy and phase diagrams of CTAB with modified counter ions CTA+[ZnCl2.Br]- named as CZN-1, CTA+[CuCl2.Br]- named as CCU-1 and CTA+[FeCl3.Br]- named as CFE-1 based upon surfactant with modified counter ions (SMCs). Four different points in microemulsion region of phase diagram were selected with different percentage composition of Smix (surfactant and co-surfactant), oil and RB (taken as water component). The interaction of RB, CCU-1, CFE-1 and CZN-1 within microemulsion environment were studied using Fluorescence spectroscopy. Emission spectra of RB in CCU-1 and CFE-1 based microemulsion confirmed that RB formed complexes with Cu and Fe ions. It was also found that RB was less soluble in CTAB based microemulsion as compared to microemulsions based on SMCs. This novel research study will expose new path for future research work related to microemulsion.

Nanocarrier-Mediated Drug Delivery via Inhalational Route for Lung Cancer Therapy: A Systematic and Updated Review.

Lung cancer is one of the most severe lethal malignancies, with approximately 1.6 million deaths every year. Lung cancer can be broadly categorised into small and non-small-cell lung cancer. The traditional chemotherapy is nonspecific, destroys healthy cells and produces systemic toxicity; targeted inhalation drug delivery in conjunction with nanoformulations has piqued interest as an approach for improving chemotherapeutic drug activity in the treatment of lung cancer. Our aim is to discuss the impact of polymer and lipid-based nanocarriers (polymeric nanoparticles, liposomes, niosomes, nanostructured lipid carriers, etc.) to treat lung cancer via the inhalational route of drug administration. This review also highlights the clinical studies, patent reports and latest investigations related to lung cancer treatment through the pulmonary route. In accordance with the PRISMA guideline, a systematic literature search was carried out for published works between 2005 and 2023. The keywords used were lung cancer, pulmonary delivery, inhalational drug delivery, liposomes in lung cancer, nanotechnology in lung cancer, etc. Several articles were searched, screened, reviewed and included. The analysis demonstrated the potential of polymer and lipid-based nanocarriers to improve the entrapment of drugs, sustained release, enhanced permeability, targeted drug delivery and retention impact in lung tissues. Patents and clinical observations further strengthen the translational potential of these carrier systems for human use in lung cancer. This systematic review demonstrated the potential of pulmonary (inhalational) drug delivery approaches based on nanocarriers for lung cancer therapy.

Unlocking Insights in IoT-Based Patient Monitoring: Methods for Encompassing Large-Data Challenges.

The remote monitoring of patients using the internet of things (IoT) is essential for ensuring continuous observation, improving healthcare, and decreasing the associated costs (i.e., reducing hospital admissions and emergency visits). There has been much emphasis on developing methods and approaches for remote patient monitoring using IoT. Most existing frameworks cover parts or sub-parts of the overall system but fail to provide a detailed and well-integrated model that covers different layers. The leverage of remote monitoring tools and their coupling with health services requires an architecture that handles data flow and enables significant interventions. This paper proposes a cloud-based patient monitoring model that enables IoT-generated data collection, storage, processing, and visualization. The system has three main parts: sensing (IoT-enabled data collection), network (processing functions and storage), and application (interface for health workers and caretakers). In order to handle the large IoT data, the sensing module employs filtering and variable sampling. This pre-processing helps reduce the data received from IoT devices and enables the observation of four times more patients compared to not using edge processing. We also discuss the flow of data and processing, thus enabling the deployment of data visualization services and intelligent applications.

Exploring the management approaches of cytokines including viral infection and neuroinflammation for neurological disorders.

Considerable evidence supports that cytokines are important mediators of pathophysiologic processes within the central nervous system (CNS). Numerous studies have documented the increased production of various cytokines in the human CNS in various neurological and neuropsychiatric disorders. Deciphering cytokine actions in the intact CNS has important implications for our understanding of the pathogenesis and treatment of these disorders. The purpose of this study is to discuss the recent research on treating cytokine storm and amyloids, including stroke, Parkinson's disease (PD), Alzheimer's disease (AD), Huntington's condition, Multi-sclerosis (MS), Amyotrophic Lateral Sclerosis (ALS). Neuroinflammation observed in neurological disorders has a pivotal role in exacerbating Aß burden and tau hyperphosphorylation, suggesting that stimulating cytokines in response to an undesirable external response could be a checkpoint for treating neurological disorders. Furthermore, the pro-inflammatory cytokines help our immune system through a neuroprotective mechanism in clearing viral infection by recruiting mononuclear cells. This study reveals that cytokine applications may play a vital role in providing novel regulation and methods for the therapeutic approach to neurological disorders and the causes of the deregulation, which is responsible for neuroinflammation and viral infection. However, it needs to be further investigated to clarify better the mechanisms of cytokine release in response to various stimuli, which could be the central point for treating neurological disorders.

Effect of dietary supplementation of wildCumin (Bunium persicum) seeds on performance, nutrient digestibility and circulating metabolites in broiler chicks during the finisher phase.

The objective of the present study was to evaluate the impact of inclusion of wild cumin seeds (WCS) on performance, nutrient digestibility and blood profile in broilers during the finisher phase. For this purpose, 360, 14 days old chicks were randomly divided into four groups designated as CONT (control), 0.5WCS, 1.0WCS and 1.5WCS with 5 replicates, which were supplemented with WCS at the rate of 0, 0.5, 1, and 1.5% respectively. On the overall, feed intake was significantly (p < 0.01) higher in the CONT compared to the 1.0WCS. At the end of the finisher phase, and overall basis, body weight and feed conversion ratio were significantly (p < 0.05) higher in 0.5WCS. Crude protein apparent digestibility in the ileum was significantly (p < 0.05) higher in 0.5WCS compared to the CONT, while crude fat digestibility was significantly (p < 0.01) higher in 0.5WCS and 1.5WCS compared to the control. Similarly, serum triglyceride was significantly (p < 0.05) lower in 0.5WC but high density lipoprotein was significantly (p < 0.05) higher in the same group. It was concluded that wild Cumin at the rate of 0.5% was superior compared to the other treatments in the diet to improve the performance, nutrient digestibility and blood metabolites in broiler during the finisher phase.

Identification of hub genes through co-expression network of major QTLs of fiber length and strength traits in multiple RIL populations of cotton.

The present study demonstrated a de novo correlation among fiber quality genes in multiple RIL populations including sGK9708 × 0-153, LMY22 × LY343 and Lumianyan28 × Xinluzao24. The current study was conducted to identify the major common QTLs including fiber length and strength, and to identify the co-expression networks of fiber length and strength QTLs harbored genes to target the hub genes. The RNA-seq data of sGK9708 × 0-153 population highlighted 50 and 48 candidate genes of fiber length and fiber strength QTLs. A total of 29 and 21 hub genes were identified in fiber length and strength co-expression network modules. The absolute values of correlation coefficient close to 1 resulted highly positive correlation among hub genes. Results also suggested that the gene correlation significantly influence the gene expression at different fiber development stages. These results might provide useful reference for further experiments in multiple RIL populations and suggest potential candidate genes for functional studies in cotton.

Correlation of histopathological patterns of OSCC patients with tumor site and habits.

INTRODUCTION: Oral cancer is considered a major global public health problem. The causes of OSCC are tobacco, alcohol, viral infections such as EBV, HPV, and herpes simplex virus, poor oral hygiene (including sharp teeth and decay), ill-fitting denture, ultraviolet (UV) exposure, nutrition, and genetic predisposition. The etiology of oral cancer varies in different populations due to area-specific etiological factors. OBJECTIVE: Finding a correlation of histopathological pattern to the tumor site and habits as an outcome of OSCC. METHODS: This cross-sectional study was conducted in Karachi, Pakistan. A total of 100 known cases of an oral squamous cell carcinoma were diagnosed with the help of biopsy reports and were examined for histopathologic features, site of the lesion, and risk habits. RESULTS: 48 years was the mean age at the time of diagnosis with a distribution of 61% men and 39% women. The frequently affected site was buccal mucosa and the prime risk habit was gutka followed by betel quid. Histologically, the degree of differentiation shows that moderately differentiated OSCC was most commonly present, while the most prevalent histopathological pattern was spindle cell carcinoma. The statistical relation between lesion site and tobacco habits was found to be significant with a p value (p = 0.01). CONCLUSION: Rates of oral squamous cell carcinoma are higher in males than females with a mean age at the time of diagnosis being less than 50 years. Frequently placing gutka in the buccal vestibule against buccal mucosa is responsible to make buccal mucosa the most common tumor site. This study provides baseline information regarding habits.

Multi-responses of O-methyltransferase genes to salt stress and fiber development of Gossypium species.

BACKGROUND: O-methyltransferases (OMTs) are an important group of enzymes that catalyze the transfer of a methyl group from S-adenosyl-L-methionine to their acceptor substrates. OMTs are divided into several groups according to their structural features. In Gossypium species, they are involved in phenolics and flavonoid pathways. Phenolics defend the cellulose fiber from dreadful external conditions of biotic and abiotic stresses, promoting strength and growth of plant cell wall. RESULTS: An OMT gene family, containing a total of 192 members, has been identified and characterized in three main Gossypium species, G. hirsutum, G. arboreum and G. raimondii. Cis-regulatory elements analysis suggested important roles of OMT genes in growth, development, and defense against stresses. Transcriptome data of different fiber developmental stages in Chromosome Substitution Segment Lines (CSSLs), Recombination Inbred Lines (RILs) with excellent fiber quality, and standard genetic cotton cultivar TM-1 demonstrate that up-regulation of OMT genes at different fiber developmental stages, and abiotic stress treatments have some significant correlations with fiber quality formation, and with salt stress response. Quantitative RT-PCR results revealed that GhOMT10_Dt and GhOMT70_At genes had a specific expression in response to salt stress while GhOMT49_At, GhOMT49_Dt, and GhOMT48_At in fiber elongation and secondary cell wall stages. CONCLUSIONS: Our results indicate that O-methyltransferase genes have multi-responses to salt stress and fiber development in Gossypium species and that they may contribute to salt tolerance or fiber quality formation in Gossypium.

A spotlight on underlying the mechanism of AMPK in diabetes complications.

OBJECTIVE: Type 2 diabetes (T2D) is one of the centenarian metabolic disorders and is considered as a stellar and leading health issue worldwide. According to the International Diabetes Federation (IDF) Diabetes Atlas and National Diabetes Statistics, the number of diabetic patients will increase at an exponential rate from 463 to 700 million by the year 2045. Thus, there is a great need for therapies targeting functions that can help in maintaining the homeostasis of glucose levels and improving insulin sensitivity. 5' adenosine monophosphate-activated protein kinase (AMPK) activation, by various direct and indirect factors, might help to overcome the hurdles (like insulin resistance) associated with the conventional approach. MATERIALS AND RESULTS: A thorough review and analysis was conducted using various database including MEDLINE and EMBASE databases, with Google scholar using various keywords. This extensive review concluded that various drugs (plant-based, synthetic indirect/direct activators) are available, showing tremendous potential in maintaining the homeostasis of glucose and lipid metabolism, without causing insulin resistance, and improving insulin sensitivity. Moreover, these drugs have an effect against diabetes and are therapeutically beneficial in the treatment of diabetes-associated complications (neuropathy and nephropathy) via mechanism involving inhibition of nuclear translocation of SMAD4 (SMAD family member) expression and association with peripheral nociceptive neurons mediated by AMPK. CONCLUSION: From the available information, it may be concluded that various indirect/direct activators show tremendous potential in maintaining the homeostasis of glucose and lipid metabolism, without resulting in insulin resistance, and may improve insulin sensitivity, as well. Therefore, in a nut shell, it may be concluded that the regulation of APMK functions by various direct/indirect activators may bring promising results. These activators may emerge as a novel therapy in diabetes and its associated complications.

Understanding the possible role of endocannabinoid system in obesity.

BACKGROUND: Maintenance of weight is essential for sustenance, well-being and to endorse prolonged life. The prevalence of obesity is increasing at an alarming rate globally, due to modern lifestyle and dietary habits. Endocannabinoids are fatty acid derivatives and numerous studies are carried out which focuses and targets their relationship with obesity, via multiple signals which have been recently known for exerting crucial role in regulating energy balance. PURPOSE: This article aims at examining the prospects of endocannabinoids in obesity via directing the role of ECs in stimulating hunger. RESULT: In last few years, irregular stimulation of endocannabinoid system has been suggested as a chief element in the progression of obesity-associated metabolic complications. Certainly, this cascade system comprises of cannabinoid type1 and 2 receptors (CB1R and CB2R) along with their endogenous lipid ligands which are responsible for enhanced feeding behavior as well as lipid metabolism. Significantly, inhibiting CB1R activity might reduce metabolic abnormality linked with obesity. CONCLUSION: Conclusion withdrawn on the basis of supporting scientific data and evidences report that the blockade of cannabinoids can serve as a therapeutic potential for treatment of obesity. Future prospective aims at assessing molecular pathways which contributes towards ECS, elicited weight control and to evaluate how these mechanisms are presently relocated into the production of novel cannabinoid drugs exhibiting enriched care.

Exploring the recent molecular targets for diabetes and associated complications.

Diabetes is likely one of the centenarian diseases which is apprehended with certainty to humans. According to established protocols of the World Health Organisation (WHO) and numerous investigated studies diabetes is analyzed as a stellar and leading health issue worldwide. Although, the implicit costs of this pathology are increasing every year, thus, there is a need to find a novel method which can provide promising results in the management of diabetes and can overcome the side effects associated with the conventional medication. Comprehensive review of this topic was undertaken through various research and review papers which were conducted using MEDLINE, BIOSIS and EMBASE database. Using various keywords, we retrieve the most relevant content for the thorough review on recent targets and novel molecular pathways for targeting diabetes and associated complications. From the detailed analysis, we have highlighted some molecular pathways and novel targets which had shown promising results in both in-vitro and in-vivo studies and may be considered as pipeline target for clinical trials. Furthermore, these targets not only abetted amelioration of diabetes but also helped in mitigation of diabetes associated complications as well. Thus, based on the available information and literature on these potential molecules, conclusive evidence can be drawn which confirms targeting these novel pathways may unleash an array of benefits that have the potential to overpower the benefits obtained from conventional therapy in the management of diabetes thereby decreasing morbidity and mortality associated with diabetic complications.

Investigating Master-Slave Architecture for Underwater Wireless Sensor Network.

A significant increase has been observed in the use of Underwater Wireless Sensor Networks (UWSNs) over the last few decades. However, there exist several associated challenges with UWSNs, mainly due to the nodes' mobility, increased propagation delay, limited bandwidth, packet duplication, void holes, and Doppler/multi-path effects. To address these challenges, we propose a protocol named "An Efficient Routing Protocol based on Master-Slave Architecture for Underwater Wireless Sensor Network (ERPMSA-UWSN)" that significantly contributes to optimizing energy consumption and data packet's long-term survival. We adopt an innovative approach based on the master-slave architecture, which results in limiting the forwarders of the data packet by restricting the transmission through master nodes only. In this protocol, we suppress nodes from data packet reception except the master nodes. We perform extensive simulation and demonstrate that our proposed protocol is delay-tolerant and energy-efficient. We achieve an improvement of 13% on energy tax and 4.8% on Packet Delivery Ratio (PDR), over the state-of-the-art protocol.

A Systematic Review of the Biological Effects of Cordycepin.

We conducted a systematic review of the literature on the effects of cordycepin on cell survival and proliferation, inflammation, signal transduction and animal models. A total of 1204 publications on cordycepin were found by the cut-off date of 1 February 2021. After application of the exclusion criteria, 791 papers remained. These were read and data on the chosen subjects were extracted. We found 192 papers on the effects of cordycepin on cell survival and proliferation and calculated a median inhibitory concentration (IC50) of 135 µM. Cordycepin consistently repressed cell migration (26 papers) and cellular inflammation (53 papers). Evaluation of 76 papers on signal transduction indicated consistently reduced PI3K/mTOR/AKT and ERK signalling and activation of AMPK. In contrast, the effects of cordycepin on the p38 and Jun kinases were variable, as were the effects on cell cycle arrest (53 papers), suggesting these are cell-specific responses. The examination of 150 animal studies indicated that purified cordycepin has many potential therapeutic effects, including the reduction of tumour growth (37 papers), repression of pain and inflammation (9 papers), protecting brain function (11 papers), improvement of respiratory and cardiac conditions (8 and 19 papers) and amelioration of metabolic disorders (8 papers). Nearly all these data are consistent with cordycepin mediating its therapeutic effects through activating AMPK, inhibiting PI3K/mTOR/AKT and repressing the inflammatory response. We conclude that cordycepin has excellent potential as a lead for drug development, especially for age-related diseases. In addition, we discuss the remaining issues around the mechanism of action, toxicity and biodistribution of cordycepin.

Effect of diet supplemented with coconut essential oil on performance and villus histomorphology in broiler exposed to avian coccidiosis.

The current research study was designed to determine the inclusion of 2% dietary essential coconut oil with and without coccidiosis challenge on performance, carcass characteristics, and intestinal histomorphology in broilers. A total of 560 broiler chicks were divided into 4 groups and then subdivided into 5 replicates. Coconut oil was used at 2% in feed, whereas coccidiosis challenged was introduced using 30,000 oocysts. The other four groups were designated as G1 (without coconut oil and without oocysts), G2 (without coconut oil with oocysts), G3 (with coconut oil without oocysts), and G4 (with coconut oil and with oocysts). The results revealed that the overall feed consumption was significantly (P < 0.01) increased in G1 and G2 than G3 and G4 groups. Overall weight gain was significantly (P < 0.01) higher in G3 compared with all other groups. Significantly (P < 0.01) better feed conversion ratio was recorded at the finisher phase in G3 and G4 groups in comparison with G1 and G2. The villus length, width, and surface area were higher (P < 0.01) in G3 compared with G2. Based on the findings of the present study, it was concluded that the use of 2% coconut oil in broiler feed improved growth performance and villus histology during coccidial challenge.

While among the 91 identified compounds 18 were found common therefore finally 73 compounds were identified in the present EI-GC-MS analysis of sample-A.

Formulation optimization, in vitro characterization and stability studies of sustain release tablets of Ketoprofen.

The aim of the current study was to formulate sustain release (SR) tablets of ketoprofen. Five batches (batch I -V) of matrix based ketoprofen tablet were prepared by dry granulation method using hydroxyl propyl methyl cellulose (15000cps). Compatibility of formulation excipients with drug was explored through FT-IR technique. Various physical and chemical parameters of all tablet batches were evaluated with multi-point dissolution profile (for 24hrs) for formulation optimization. Release kinetics of trials was estimated by model dependent and independent methods. Formulations having excellent quality attributes were then compared with marketed ketoprofen SR tablets. Accelerated stability study was also conducted to compute the shelf life of the optimized formulation. FT-IR scans illustrated the compatibility of ketoprofen with all tablet excipients. On the basis of testing results and controlled release pattern batch II was set to be an optimized trial having shelf life of 37 months. All trial batches (batch I-V) and the marketed brand exhibited highest linearity towards zero order and Korsmeyer-Peppas model with non-fickian anomalous transport (n=0.541-0.655).

Method for Handling Massive IoT Traffic in 5G Networks.

The ever-growing Internet of Things (IoT) data traffic is one of the primary research focuses of future mobile networks. 3rd Generation Partnership Project (3GPP) standards like Long Term Evolution-Advanced (LTE-A) have been designed for broadband services. However, IoT devices are mainly based on narrowband applications. Standards like LTE-A might not provide efficient spectrum utilization when serving IoT applications. The aggregation of IoT data at an intermediate node before transmission can answer the issues of spectral efficiency. The objective of this work is to utilize the low cost 3GPP fixed, inband, layer-3 Relay Node (RN) for integrating IoT traffic into 5G network by multiplexing data packets at the RN before transmission to the Base Station (BS) in the form of large multiplexed packets. Frequency resource blocks can be shared among several devices with this method. An analytical model for this scheme, developed as an r-stage Coxian process, determines the radio resource utilization and system gain achieved. The model is validated by comparing the obtained results with simulation results.

Liquid phase synthesis of aromatic poly(azomethine)s, their physicochemical properties, and measurement of ex situ electrical conductivity of pelletized powdered samples.

Aromatic bis-aldehydes have been used as building blocks in the synthesis of polyazomethines (a class of conjugated Schiff bases) and their physicochemical properties have been studied. Six dialdehydes have been synthesized, 3a-3f, via etherification reaction between aromatic diols (2a-2f) and 4-fluorobenzaldehyde (1) (see Scheme 1), and then polymerized with 1,4-phenylenediamine (4a) and 4,4'-oxydianiline (4b) (see Scheme 2). The chemical structures of the bis-aldehydes were elucidated by FTIR, 1H NMR and 13C NMR spectroscopic studies, elemental analysis and single crystal whereas the polymers were studied by FTIR and NMR spectroscopy. Their physicochemical properties were examined by their inherent viscosity, organosolubility, differential scanning calorimetry, X-ray powder diffraction, thermogravimetric analysis, solvatochromism, and photoluminescence. We report the electrical conductivity of each polymer measured by the four probe method. The results indicate that the electrical conductivity of polymers lies in range 0.019-0.051 mScm-1 which is reasonably higher than any reported value.

The effects of particle size, milling method, and thermal treatment of feed on performance, apparent ileal digestibility, and pH of the digesta in laying hens.

Various milling methods result in different particle size distributions and, in combination with mash and thermal treatment (expandate) of the feed, may have an impact on nutrient digestibility, pH of the digesta and subsequently the performance of an animal. Since this aspect has not been widely considered in laying hens, the objective of the present study was to investigate the effects of milling method, expansion, and particle size of feed on performance, apparent ileal nutrient digestibility, and pH of digesta in laying hens. Twelve variants of the same diet were produced. Four different milling techniques (hammer mill, roller mill, disc mill, and wedge-shaped disc mill) were used to grind the feed cereals. Coarse feed was obtained from all four mills. Additionally, fine feed was obtained from the hammer mill and the roller mill. Each of the six feed variants was offered as mash or expandate, resulting in a total of 12 treatments. The duration of the experimental period was 21 days. A total of 576 layers, each 19 weeks of age, were used in eight replicates. The statistical analysis for the four milling methods and two thermal treatments was performed using a 4×2 factorial arrangement. The effect of particle size was investigated using a 2×2×2 factorial arrangement including the coarse and fine particle sizes that were produced with the hammer mill and the roller mill as well as the mash and expandate. The animal performance and the pH of the digesta were not affected by the treatments. Ileal digestibility of starch was significantly improved by feeding mash compared to expandate (P=0.013) and by feeding coarse compared to fine feed (P=0.028). Based on this study, the tested milling methods can be used for the production of feed for laying hens without affecting performance and digestibility of nutrients.

Nanocarrier Mediated Intranasal Drug Delivery Systems for the Management of Parkinsonism: A Review.

The transport of drugs to the brain becomes a key concern when treating disorders of the central nervous system. Parkinsonism is one of the major concerns across the world populations, which causes difficulty in coordination and balance. However, the blood-brain barrier is a significant barrier to achieving optimal brain concentration through oral, transdermal, and intravenous routes of administration. The intranasal route with nanocarrier-based formulations has shown potential for managing Parkinsonism disorder (PD). Direct delivery to the brain through the intranasal route is possible via the olfactory and trigeminal pathways using drug-loaded nanotechnology-based drug delivery systems. The critical analysis of reported works demonstrates dose reduction, brain targeting, safety, effectiveness, and stability for drug-loaded nanocarriers. The important aspects of intranasal drug delivery, PD details, and nanocarrier-based intranasal formulations in PD management with a discussion of physicochemical characteristics, cell line studies, and animal studies are the major topics in this review. Patent reports and clinical investigations are summarized in the last sections.
