Introduction Hypertension (HTN) is considered one of the most frequent life-threatening noncommunicable illnesses. Because HTN has a significant public health impact on cardiovascular health status and healthcare systems in India, it is critical to study Indian clinicians' approaches to HTN management. Methodology This was a cross-sectional, multicentric, non-interventional, and single-visit study that aimed to gather data from across India and examine sociodemographic characteristics and clinician treatment choices in the management of HTN in Indian individuals. As a result, building an information platform about HTN is critical to preventing and controlling this growing burden. Results A total of 5298 patients were recruited in the study from 1061 study centers across India. Among the study patients, 66.67% were females with a mean age of 53.95 ± 14.4, and 66.28% of hypertensive patients presented comorbidities. Among the known risk factors for HTN, 2227 (44.5%) were smokers, while 2587 (51.7%) had sedentary lifestyles. A family history of HTN in either one or both parents was seen in 1076 (21.50%) patients. In management, 40.40% of patients were on anti-hypertensive monotherapy. Amlodipine (41.8%) in monotherapy and amlodipine + metoprolol (32.34%) in combination therapy were the most commonly prescribed antihypertensive. Conclusion Management of HTN can be improved by imparting patient education and awareness about the need for medication compliance, lifestyle modifications, and regular follow-up clinic visits.
With excellent mechanical properties and distinct solidification, the AZ31B series magnesium alloy has great potential for targeting engineering applications and synthesized via die casting process found a drawback on oxidation results porosity and reduced mechanical properties. Here, the magnesium alloy AZ31B series nanocomposite was synthesized with varied weight percentages of zirconium dioxide nanoparticles through a liquid metallurgy route with an applied stir speed of 200 rpm under an argon nature. With the help of a scanning electron microscope, the distribution of particles in the composite surface was found to be homogenous and void-free surface, which output results in less percentage of porosity (<1 %), and the composite contained 6 wt% ZrO2 offers superior yield strength (212 ± 3 MPa), tensile strength (278 ± 2 MPa), and impact strength of 16.4 ± 0.4 J/mm2. In addition, 8 wt% ZrO2 blended composite showed the maximum microhardness value (78.3 ± 1 HV). The best-enhanced result of NC3 (AZ31B/6 wt% ZrO2) is suggested for lightweight to high-strength structural applications.
Myoepithelioma is an uncommon benign tumor of the orofacial region arising from the salivary glands. These tumors are composed of specifically myoepithelial cells lacking ductal differentiation and were initially considered as a type of pleomorphic adenoma. Though they commonly arise from the parotid gland, there are a few cases that emerge from the minor salivary glands of the palate and oral cavity. Myoepitheliomas resemble many other tumors arising from the palate including pleomorphic adenoma. This report depicts a case of myoepithelioma of the minor salivary gland of the palate in a 23-year-old patient and the successful management of the lesion.
Introduction: The present inquiry seeks to investigate whether the current regimens of QSEs (Quadriceps-Strengthening Exercises) aggravate the disease while mitigating symptoms. Materials and methods: A comparative study was conducted on 32 patients with medial compartment osteoarthritis of knees. While the neutral group of 16 patients was constituted of those with an anatomical-lateral-femoro-tibial-angle (aFTA) 176-180º, varus group comprised an equal number of patients with an aFTA >180º. A home-based 12-week strength-training program involving weekly visits to hospital for supervised sessions was administered. The outcome measures were visual-analog-scale (VAS), medial patello-femoral joint tenderness (MPFJT), time-up-and-go-test (TUGT), stair-climb test, step test, WOMAC, IKDC scores, aFTA, hip-knee-ankle (HKA) angle, lateral-tibio-femoral-joint-separation (LTFJS), and horizontal-distance-from-centre-of-knee-to-Mikulicz-line. Results: There was a significant increase in quadriceps strength (p<0.01) in both groups. Values for neutral group with VAS score (p=0.01), MPFJT (p=0.01), TUGT (p=0.01), timing of the stair climb test (p=0.01), WOMAC (p<0.01), and IKDC (p=0.03) were better compared to varus group with VAS score (p=0.13), MPFJT (p=0.03), TUGT (p=0.90), timing of stair climb test (p=0.68), WOMAC (p<0.02), and IKDC (p=0.05). Varus group also showed an increase in aFTA and LTFJS in 12 patients, increase in HKA in 11, and increase in horizontal distance from the centre of knee to the Mikulicz line in 7 patients. Conclusion: The present study brings to the fore the paradoxical role played by QSEs in management of medial knee OA. While there is a radiological progression of the disease in both neutral and varus mal-aligned knees more so in the latter than the former.
The present study aimed to investigate the chemical profile, antioxidant, and enzyme inhibition properties of extracts from fruits and aerial parts (leaves and twigs) of Tamarix aphylla and T. senegalensis. Hexane, dichloromethane, ethyl acetate (EtOAc), and methanol extracts were prepared sequentially by maceration. Results revealed that EtOAc extracts of T. senegalensis and T. aphylla fruits contained the highest total phenolic content (113.74 and 111.21 mg GAE/g) while that of T. senegalensis (38.47 mg RE/g) recorded the highest total flavonoids content. Among the quantified compounds; ellagic, gallic, 3-hydroxybenzoic, caffeic, syringic, p-coumaric acids, isorhamnetin, procyanidin B2, and kaempferol were the most abundant compounds in the two species. EtOAc extracts of the two organs of T. senegalensis in addition to MeOH extract of T. aphylla aerial parts displayed the highest chelating power (21.00-21.30 mg EDTAE/g, p > 0.05). The highest anti-AChE (3.11 mg GALAE/g) and anti-BChE (3.62 mg GALAE/g) activities were recorded from the hexane and EtOAc extracts of T. senegalensis aerial parts and fruits, respectively. EtOAc extracts of the fruits of the two species exerted the highest anti-tyrosinase (anti-Tyr) activity (99.44 and 98.65 mg KAE/g, p > 0.05). Also, the EtOAc extracts of the both organs of the two species exhibited highest anti-glucosidase activity (0.88-0.90 mmol ACAE/g, p > 0.05) while the best anti-α-amylase activity was recorded from the dichloromethane extract of T. senegalensis fruits (0.74 mmol ACAE/g). In this study, network pharmacology was employed to examine the connection between compounds from Tamarix and their potential effectiveness against Alzheimer's disease. The compounds demonstrated potential interactions with pivotal genes including APP, GSK3B, and CDK5, indicating a therapeutic potential. Molecular docking was carried out to understand the binding mode and interaction of the compounds with the target enzymes. Key interactions observed, such as H-bonds, promoted the binding, and weaker ones, such as van der Waals attractions, reinforced it. These findings suggest that these two Tamarix species possess bioactive properties with health-promoting effects.
BACKGROUND AND PURPOSE: Chronic inflammation plays a pivotal role in the development of Type 2 diabetes mellitus (T2DM). Previous studies have shown that haem oxygenase-1 (HO-1) plays a proinflammatory role during metabolic stress, suggesting that HO-1 inhibition could be an effective strategy to treat T2DM. However, the application of HO-1 inhibitors is restricted due to solubility-limited bioavailability. In this study, we encapsulated the HO-1 inhibitor, zinc protoporphyrin IX (ZnPP), within nanoparticles and investigated their role in regulating glucose homeostasis and chronic inflammation during obesity. EXPERIMENTAL APPROACH: We delivered DMSO-dissolved ZnPP (DMSO-ZnPP) and ZnPP-laden nanoparticles (Nano-ZnPP) to diet-induced obese male mice for 6 weeks. Glucose and insulin tolerance tests were carried out, liver and adipose tissue gene expression profiles analysed, and systemic inflammation analysed using flow cytometry. KEY RESULTS: Nanoparticles significantly increased the delivery efficiency of ZnPP in both cells and mice. In mice with diet-induced obesity, inhibition of HO-1 by Nano-ZnPP significantly decreased adiposity, increased insulin sensitivity, and improved glucose tolerance. Moreover, Nano-ZnPP treatment attenuated both local and systemic inflammatory levels during obesity. Mechanistically, Nano-ZnPP significantly attenuated glucagon, TNF, and fatty acid synthesis signalling pathways in the liver. In white adipose tissue, the oxidative phosphorylation signalling pathway was enhanced and the inflammation signalling pathway diminished by Nano-ZnPP. Our results show that Nano-ZnPP has better effects on the improvement of glucose homeostasis and attenuation of chronic inflammation, than those of DMSO-dissolved ZnPP. CONCLUSIONS AND IMPLICATIONS: These findings indicate that ZnPP-laden nanoparticles are potential therapeutic agents for treating T2DM.
The correlation between viral infections and the onset of autoimmune conditions has long attracted the scientific community. With the COVID-19 pandemic impacting the world like never before, we have a unique chance to better understand this complex disease and uncover its origin. In light of this, we performed a systematic review of the incidence and prevalence of newly diagnosed autoimmune diseases following the COVID-19 pandemic. We undertook an extensive literature review from 2012 to 2023, by using electronic databases such as Medline, Web of Science, PubMed, Cochrane Library, and supplementary sources like scholarly articles. Our review encompassed various types of studies, including trials, commentaries, and editorials. To evaluate bias, we adopted a recommended approach, employing a two-part tool to scrutinize five distinct domains: selection bias, performance bias, attrition bias, selective reporting, and other biases. In this review, a total of 14 studies were incorporated. On the basis of the findings of the present investigation, the average age of included patients was approximately 56.13 years, and the maximum were male. After the, meticulous examination we stated that there was a significant increase in inflammatory biomarkers, including ferritin, C-reactive protein (CRP), lactate dehydrogenase (LDH), D-dimer and Interleukins IL-6. The majority of patients had an elevated level of CRP. We conclude that there is a strong association between COVID-19 and a higher risk of various types of autoimmune diseases. In order to develop effective plans for the current pandemic as well as the post-pandemic period that follows, healthcare providers must recognize these autoimmune manifestations.

Managing systemic lupus erythematosus (SLE) is challenging because of its diverse symptoms, relapses, and issues related to immunosuppressive therapy. Hence, the management of autoimmune disorder has become a hot topic in this era. Thus, the study aims to predict disease severity in SLE cases by assessing the value of neutrophil-lymphocyte ratio and platelet-lymphocyte ratio. In this study, we included a total of 80 patients, of which 40 were controls and 40 were experimental group. We gathered the demographic data and each patient provided informed consent. Furthermore, the clinical examinations were done, and results were noted. The study compared 40 SLE patients with 40 controls. SLE patients had lower complement levels, higher rates of LN and encephalopathy, and elevated Hs-CRP and ESR. They also showed lower WBC, neutrophil, lymphocyte, and platelet counts, along with higher NLR and PLR. Higher SLEDAI scores correlated with elevated Hs-CRP and ESR, and lower C3. Neutrophils positively correlated with NLR, while lymphocytes negatively correlated with SLEDAI scores, NLR, and PLR. Platelets did not significantly correlate with these markers. SLE patients showed higher rates of LNand encephalopathy, elevated inflammatory markers, and altered blood cell counts. Lower SLEDAI scores correlated with less inflammation and higher C3 levels, potentially indicating disease severity. Neutrophils were closely linked to disease activity, while lymphocytes showed a strong negative correlation. Platelet count was not a significant marker. Understanding these aspects could improve diagnosis and management.

Background: Propofol is the drug of choice for procedural sedation. The addition of α2 agonist dexmedetomidine may improve the safety profile of the procedure by providing stable hemodynamics, better sedation quality, and decreasing the side effects of each drug during elective endoscopic retrograde cholangio-pancreaticography (ERCP). Materials and Methods: Eighty patients aged between 18 and 60 years were distributed randomly into two groups. The dexmedetomidine + propofol group (group DP) received an injection of dexmedetomidine at the dose of 1 mcg/kg in 100 mLsaline, and the propofol group (group P) received plain 100 mL normal saline over 10 min. Subsequently, both groups received a bolus dose of injection propofol 1 mg/kg as sedation, and a modified observer's assessment of alertness/sedation score (MOASS) score was assessed, followed by infusion at the rate of 50 mcg/kg/min during the procedure. A rescue bolus dose (20 mg) of propofol was administered when the patient showed signs of inadequate sedation or analgesia in both groups. Cardiovascular and respiratory parameters were recorded every 10 min throughout the procedure. Post-procedure modified Aldrete score was evaluated for 30 min, and the endoscopist's score was noted at the end of the procedure. Results: There was a significant difference (P = 0.001) in the additional number of rescue doses of propofol administered in group DP (3.47 ± 0.77) as compared to group P (8.78 ± 1.11). The total dose of propofol was lower in group DP (316.59 ± 43.29 mg) than in group P (443 ± 41.1 mg) with P value = 0.001. Statistically significant differences in the hemodynamic values were observed in group DP during infusion (P value < 0.05) of dexmedetomidine and throughout the procedure (P < 0.05) when compared with group P. Endoscopists graded the satisfaction score as very high (3.477 ± 0.77) in group DP. Conclusion: The addition of dexmedetomidine to propofol during ERCP provided better and safer sedation.
Receptor-mediated polyester drug delivery systems have tremendous potential for improving the clinical performance of existing pharmaceutical drugs. Despite significant progress made in this area, it remains unclear how and to what extent the polyester nanoparticle surface topography would affect the in vitro, ex vivo and in vivo performance of a drug, and if there exists a correlation between in vitro and in vivo, as well as healthy versus pathophysiological states. Herein, we report a systematic investigation of the interactions between ligands and receptors as a function of the linker length, two-carbon (2C) versus four-carbon (4C). The in vitro, ex vivo and in vivo in healthy models validate the hypothesis that 4C has better reach and binding to the receptors. The results indicate that 4C offered better performance over 2C in vivo in improving the oral bioavailability of insulin (INS) by 1.1-fold (3.5-fold compared to unfunctionalized nanoparticles) in a healthy rat model. Similar observations were made in pathophysiological models; however, the effects were less prominent compared to those in healthy models. Throughout, ligand decorated nanoparticles outperformed unfunctionalized nanoparticles. Finally, a semimechanistic pharmacokinetic and pharmacodynamic (PKPD) model was developed using the experimental data sets to quantitatively evaluate the effect of P2Ns-GA on oral bioavailability and efficacy of insulin. The study presents a sophisticated oral delivery system for INS or hydrophilic therapeutic cargo, highlighting the significant impact on bioavailability that minor adjustments to the surface chemistry can have.

Bifunctional electrocatalysts are the attractive research in the hydrogen evolution reaction (HER) and the oxygen evolution reaction (OER) in the overall water-splitting reactions. The design and development of the cost-effective OER/HER bifunctional electrocatalysts with superior catalytic activity are still remaining as the big challenges. Herein, we have developed the CuO-ZnO nanocomposite as a bifunctional OER/HER electrocatalyst via simple chemical precipitation method. The nanocomposite was investigated for its crystalline structure, surface morphology and the functions of elements using XRD, FT-IR, SEM, TEM and XPS characterization techniques, respectively. The nanocomposite exhibited the excellent activity for the overall water-splitting in an alkaline medium. The CuO-ZnO nanocomposite showed the less onset potential of 1.4 and 0.15 V versus RHE in 1M KOH (Tafel slopes value of 0.180 and 0.400 V dec-1) for OER and HER, respectively. Hence, the as-prepared bifunctional electrocatalyst displayed the high stability for 10 h in the water electrolysis processes.
The study focused on the production of the tyrosinase enzyme from Streptomyces sp. MR28 and its potency in removal of phenol content from water using free and immobilized tyrosinase enzyme. The tyrosinase was produced by Streptomyces sp. MR28 in liquid tyrosine broth medium, and it was further purified to near its homogeneity by employing, precipitation, dialysis, and column chromatography. After the purification, 44.49% yield with a 4 fold purification was achieved. The characterization of the purified enzyme showed a single major peak on HPLC and a solitary band on SDS-PAGE. The purified tyrosinase enzyme was active at a pH of 7.0 and a temperature of 30 °C. Further immobilization of purified tyrosinase was performed using the sodium alginate entrapment method. The capacity of the purified tyrosinase to remove phenol in water was evaluated by spectrophotometric method. The free tyrosinase enzyme-treated solutions showed a gradual decrease in the concentration of phenol with increased incubation time at 30 °C and 40 °C, at 90 min of the incubation time, it showed maximum efficacy in removing phenol from the solution. At 50 °C and 60 °C, the free tyrosinase enzyme exhibited very less capacity to remove the phenol. The immobilized enzyme showed good capacity for the removal of phenol from the solutions; the concentration of phenol in the solution decreased with an increase in the incubation time. At temperatures of 40 °C and 50 °C, the immobilized tyrosinase enzyme beads showed significant removal of phenol from the solution, and at temperatures of 30 °C and 60 °C, they also exhibited good capacity for the removal of phenol. At the end of the 90 min incubation period, it exhibited good capability. The current study suggests using immobilized microbial tyrosinase enzyme can be used for the removal of phenol from the contaminated water in a greener manner.
BACKGROUND OBJECTIVES: Scrub typhus, caused by Orientia tsutsugamushi present in small mammals harbouring the ectoparasites. A study was undertaken to detect the pathogen present in small mammals and its ectoparasites in the scrub typhus-reported areas. METHODS: The small mammals (rodents/shrews) and its ectoparasites were screened for O. tsutsugamushi using nested PCR amplification of the groEL gene. Small mammals were collected by trapping and screened for ectoparasites (mites, ticks and fleas) by combing method. RESULTS: All the chigger mites collected were tested negative for O. tsutsugamushi . Interestingly, adult non-trombiculid mites ( Oribatida sp., Dermanyssus gallinae ), fleas ( Xenopsylla astia, X. cheopis, Ctenophalides felis and Ctenophalides sp.) and ticks ( Rhipicephalus sanguineus , R. haemaphysaloides ) screened were found to be positive for O. tsutsugamushi , which the authors believe is the first report on these species globally. Bandicota bengalensis with O. tsutsugamushi infection is reported for the first time in India. The O. tsutsugamushi groEL sequences from the positive samples were similar to the reference strains, Karp and Ikeda and phylogenetically clustered in clade IV with less evolutionary divergence. The blood samples of Rattus rattus , Suncus murinus and B. bengalensis collected from this area were tested positive for O. tsutsugamushi ; interestingly, the sequence similarity was much pronounced with their ectoparasites indicating the transmission of the pathogen to host or vice versa . INTERPRETATION CONCLUSIONS: The outcome of the present investigations widened our scope on the pathogens present in ectoparasites and rodents/shrews from this area. This will help to formulate the required vector control methods to combat zoonotic diseases.

BREVIS RADIX (BRX) is a small plant-specific and evolutionary conserved gene family with divergent yet partially redundant biological functions including root and shoot growth, stomatal development and tiller angle in plants. We characterized a BRX family gene from wheat (Triticum aestivum) by gain-of-function in Arabidopsis. Overexpression of TaBRXL2A resulted in longer primary roots with increased root meristem size and higher root growth under control and exogenous hormone treatments as compared to wild type (Col-0) plants. Overexpression lines also exhibited significant differences with the wild type such as increased rosette size, higher leaf number and leaf size. At reproductive stage, overexpression lines exhibited wider siliques and higher grain weight per plant. Under drought stress, overexpression lines exhibited enhanced drought tolerance in terms of higher chlorophyll retention and lower oxidative stress, thereby leading to significant recovery from drought stress. The analysis suggests that the inherent lower stomatal density in the leaves of overexpression lines and higher stomatal closure in response to ABA might contribute to lower water loss from the overexpression lines. Furthermore, TaBRXL2A protein showed membrane localization, presence of conserved residues at N-terminal for palmitoylation, and phosphosites in the linker region which are prescribed for its potential role in protophloem differentiation and stomatal lineage. Thus, we identified a TaBRX family gene which is involved in developmental pathways essential for plant growth, and also enhances drought tolerance in Arabidopsis.

Differentiated Thyroid carcinoma (DTC) with distant skeletal metastases is associated with a very poor prognosis and are unfortunately resistant to radioiodine therapy (RIT). Surgical removal of the metastases in such selected cases is a beneficial adjunct to RIT. We report two cases of DTC with sternal metastases whom we successfully managed with surgical resection of the sternal lesion with reconstruction of the chest wall defect using titanium mesh implant and myocutaneous flap.
An analytical quality by design-based high-performance liquid chromatography method for determining metformin (MET) and sitagliptin (SIT) in stress-degraded samples was developed and validated. The analytical target profile and risk assessment-driven critical method variables, for example, pH, % aqueous, and buffer concentration, were studied for their effect on method responses of retention time and resolution using a central composite design. The correlation regression coefficient was more than 0.8, and variables interaction was significant on method responses with curvature effect. The method operable design region afforded an aqueous range of 55%-70% and an ortho-phosphoric acid buffer of 0.1% with a pH of 3.0-4.0 as a robust region for the suitable method performance characteristics. The separation of MET and SIT from their degradants (m/z 85.0509; m/z 193.0694) on the C8 column was achieved using a mobile phase consisting of 0.1% ortho-phosphoric acid and methanol (60:40% v/v; pH 3.0). The optimized method eluted MET and SIT at 4.3 ± 0.2 and 7.1 ± 0.2 min, respectively, with acceptable specificity and resolution. The linearity ranges of 25-250 µg/mL (r2 : 0.9982) and 5-50 µg/mL (r2 : 0.9989) was established for MET and SIT, respectively. The % recovery (98.81%-102.17%), precision (0.55%-1.65%), and robustness study for method variables were acceptable.

There have been growing apprehensions and concerns regarding the increasing presence of plastic pollutants in the holiest river of India, the Ganga, and its major tributary, Yamuna. In response to this issue, the current study aimed to conduct a comprehensive investigation of the seasonal and spatial distribution of macro to microplastics (MPs) in the surface water, water column, and sediments from the River Ganga and Yamuna. MP samples were collected from various points of these Rivers, including upstream, downstream, and drainage points around the vicinity of Haridwar, Agra, Prayagraj, and Patna cities. With a significant seasonal variation, the estimated MPs and plastic flux were higher during the wet season than during the dry season. MPs sized 300 µm-1 mm and fibre-shaped blue and black colored MPs were pre-dominant in both rivers. Polyacrylamide, polyamide, and polyvinyl chloride were the most ascertained polymers. MPs including hazardous polymers (hazard score >1000) may pose a risk to the population of Indo-Gangetic Plain via direct and indirect exposure to MPs. The information provided in this study could serve as a starting point for the action plan required by municipal corporations to mitigate plastic pollution and target the possible sources at each location.
