The Effect of Added Mass on Pulmonary Function

A comparative study of the volume-velocity parameters of the human external respiration system was carried out under the influence of an additional weight load: a body armor weighing 11 kg and a backpack weighing 15 kg. The nature of changes in the main spirometric parameters under the influence of an added mass is typical for restrictive disorders of pulmonary function. A marked decrease in forced vital capacity (FVC) and forced expiratory volume in 1 second (FEV1) values was observed when performing the test with a protective vest. In the conditions of a combination of body armor and a backpack, these changes were more pronounced (p 0.01). At the same time, there were no significant changes in the Tiffno index values (FEV1/FVC). In addition, a significant decrease in the values of maximum voluntary ventilation (MVV) was revealed by 8.1% under the influence of body armor, and by 18.5% with a combination of a vest and a backpack relative to the control (p 0.01). A significant correlation was shown between the maximum force of contraction of the inspiratory muscles and the maximum voluntary ventilation of the lungs both in the control and with an additional weight load. It is possible that the inspiratory muscles training, aimed at increasing their strength and endurance, can be an effective strategy for minimizing the adverse effects of increased weight load when performing work with special protective equipment in various areas of human professional activity.

Analytical modelling of halide perovskite material based hybrid biosensor to detect formalin using surface plasmon resonance strategy

The recurring consumption of formalin, a notorious preservative, can lead to a variety of lethal diseases and cause significant morbidity, highlighting the pressing need for its precise detection in developing nations. Hence, in this article, a Kretschmann-configuration-based hybrid surface plasmon resonance (SPR) biosensor is proposed and analysed numerically for formalin detection. The sensor heterostructure consists of five monolayers, namely BAK1 prism, WS2, silver, FASnI3 halide perovskite (HP), and 2D black phosphorous (BP). The influence of an additional metal oxide layer (ZnO, TiO2, SiO2, Al2O3, and MoO3) over the metallic layer is also investigated w.r.t. major performance indicators such as sensitivity, detection accuracy, quality factor, and figure of merit. Here, BP and HP jointly act as biomolecular recognition elements. Chitosan serves as a probe to react with formalin, which acts as the target molecule. Using the attenuated total reflection (ATR) concept and Fresnel equations, we’ve employed angular interrogation and transfer matrix approaches to detect the concentration of formalin by monitoring the variations in the minimum reflectance and maximum transmittance attributors in relation to SPR angle and SPR frequency (SPRF), respectively. The simulation findings demonstrate a minimal variation in SPR angle and SPRF for improper formalin sensing, confirming its absence in liquid solution. In contrast, the aforesaid attributors show significantly measurable changes when formalin is properly sensed, confirming its presence. We demonstrate that adding MoO3 over the Ag layer can enhance the detection accuracy of our primary HP-based SPR biosensor to a maximum of 55.6 %. The finite difference time domain (FDTD) technique is utilized to examine the distribution of electric fields within this biosensor structure to showcase the distinct contributions of HP and metal oxide. In the end, our simulation work is validated by a comparative study of the performance parameters with a few of the previous works on formalin detection.

Unveiling Oxidative Stress Dynamics: A Comparative Study of Biochemical and Anti-Oxidative Parameters in Thyroid Dysfunction

Background: The prevalence of thyroid dysfunction is significant, and its association with oxidative stress and biochemical changes is well recognized. Thyroid hormones are crucial in maintaining oxidative balance and regulating the body's metabolic processes to protect against cellular damage.Objectives: The study aimed to compare biochemical and oxidative stress parameters in rat models of hypothyroidism and hyperthyroidism.Materials and Methods: This research, conducted from September 14 to October 21, 2023, involved 21 male Wistar divided into hypothyroid (n=7), hyperthyroid (n=7), and control (n=7), respectively. Hypothyroidism and hyperthyroidism were induced using propylthiouracil (PTU) and levothyroxine (LTX), respectively. The study assessed serum biochemical parameters, including uric acid (UA), lactate dehydrogenase (LDH), alkaline phosphatase (ALP), low-density lipoprotein (LDL), high-density lipoprotein (HDL), and total cholesterol (TC), as well as oxidative stress parameters, such as total antioxidant capacity (TAC) after 5-weeks.Results: The study found that the hypothyroid group exhibited decreased TAC (40±4) compared to the hyperthyroid (45±6) and control (50±5; p=0.012) groups. UA levels were higher in hypothyroid rats (4.2±1.0 mg/dL). Both hypothyroid (200±18 U/L) and hyperthyroid (210±20 U/L) rats showed increased LDH levels compared to the control group (180±15 U/L). Additionally, LDL cholesterol was elevated in hypothyroid (55±8 mg/dL) and reduced in hyperthyroid rats (30±5 mg/dL), while HDL decreased in both groups.Conclusion: Hypothyroidism is associated with significantly lower TAC and higher levels of UA and LDH, indicating oxidative stress and cellular damage. Conversely, hyperthyroidism leads to altered lipid metabolism, as evidenced by decreased LDL and HDL cholesterol levels. Keywords: Anti-oxidants, Lipid metabolism, Rats, Thyroid disorders.

Argentine Malbec market: comparative study of general chemical parameters and sensory properties within low, medium and high price segments

Malbec, Argentina's emblematic wine, is appreciated worldwide for its unique characteristics and distinctive organoleptic profile. As demand for Malbec wines increases locally in Argentina and international markets, there is a need to better understand the relationship between the price of these wines and their chemical and sensory characteristics. The aim of this study was to describe and quantify the sensory attributes and chemical parameters (in particular, phenolics) of Argentinean Malbec wines of different price segments. In order to observe the differences between each price range, the eight best-selling wines from the low, medium, and high price categories were analysed. Wine general analytical parameters and phenolics composition were determined and a descriptive analysis was performed with a trained panel. The results show that it was only possible to differentiate between the high- and low-price ranges. Both ranges exhibited variability, including different types of wines. Significant differences were identified in several parameters, such as O.D.280, titratable acidity, malic acid, volatile acidity, alcohol, glucose and total sugars. There were also significant differences in anthocyanins, LPP, SPP, TPP and tannins. The high-price range was characterised by higher alcohol content, greater polyphenol concentration and greater colour intensity. Sensorially, they were distinguished by the descriptors wood, astringency and colour. The low-price range was associated with low colour intensity and higher total sugar content. This is the first study to clearly establish the sensory differences among different price ranges of Argentine wines. Our study demonstrated that wine pricing is not determined in a subjective or arbitrary manner; rather, wines produced for a specific segment are intentionally designed to achieve the desired sensory and chemical characteristics.

Comparative Study of Red Blood Cell Parameters in Different Hemoglobinopathies Diagnosed by HPLC at a Tertiary Care Hospital, Rajkot, Gujarat

Background: Inherited disorders of hemoglobin (hemoglobinopathies) are the most common genetic disorders in the world with 7% prevalence. Thalassemia and sickle cell anemia are the most prevalent hemoglobinopathies in India. Screening and diagnosis of hemoglobinopathies require a comprehensive evaluation combining clinical and family history, blood counts, red blood cell indices, and molecular analysis. Aims and Objective: (1) To differentiate the type of hemoglobinopathies on the basis of red cell parameters, (2) to assess the spectrum of hemoglobinopathies, and (3) to study the age at diagnosis and genderwise distribution of various hemoglobinopathies. Material and Methods: A prospective observational study over a period of 1 year (August 2020 to July 2021) at a tertiary care hospital, Rajkot, Gujarat. All indoor patients’ samples were sent for complete blood count (CBC), peripheral smear examination, reticulocyte count, sickling test, and high-performance liquid chromatography (HPLC). Result: A total of 140 subjects were included in the final analysis. The mean age at diagnosis was 24.7 ± 10.5 years; 48 participants were male, and the remaining 92 were female with an M:F ratio of 0.5:1. The most common hemoglobinopathy in this study was sickle cell trait (40 cases, 28.6%). Conclusion: To reduce the burden of various hemoglobinopathies, screening is recommended as a part of antenatal checkup and in infants after 6 months of age in high-prevalence districts for particular hemoglobinopathies via CBC including RBC indices and HPLC.

Changes in echocardiographic parameters after hemodialysis session in a North African pediatric population with end-stage renal disease and without known heart disease.

Children undergoing long-term hemodialysis (HD) face a reduction in life expectancy mostly due to cardiovascular mortality. Effects of HD on cardiac function have not been fully elucidated in pediatric population. This study aimed to assess HD session impact on cardiac function in pediatric patients using conventional and strain echocardiography. We performed a prospective, comparative study of echocardiographic parameters before and after single HD session in a chronic HD pediatric population. We enrolled between the 1st and 30th September 2023, all consecutive patients with end-stage renal disease (ESRD) aged up to 18 years old on maintenance HD three times weekly for at least three months. All patients underwent conventional and left ventricular (LV) longitudinal strain echocardiography in a window of 30-60 minutes before and after HD. 23 patients, 14.8 ± 2.1 years old and 47.8% male, were enrolled. Reductions in body weight and blood pressure were observed after HD, whereas heart rate increased. Significant decrease in LV and left atrial diameters and volumes after HD session were observed. Mitral peak E velocity, as well as average E/e' were significantly lower after HD. Although LV ejection fraction was unchanged, global longitudinal strain for LV was significantly reduced after dialysis (-17.3 ± 3.0% vs. -14.9 ± 2.4%, p=4.10-8). Patent deterioration in LV systolic function following HD was identified by speckle tracking echocardiography (STE). STE has the potential to unmask early myocardial dysfunction even when there is no evident alteration in conventional systolic function parameters in children with ESRD.

Comparative Study of Coagulation Profile and Haematological Parameters in Pregnancy-Induced Hypertension (PIH).

Background Pregnancy-induced hypertension (PIH) is a major cause of maternal and fetal morbidity and mortality. PIH, including gestational hypertension, pre-eclampsia, and eclampsia, often leads to significant alterations in coagulation profiles and haematological parameters, posing risks for thromboembolic and haemorrhagic complications. This study aimed to compare the coagulation and haematological parameters between women with PIH and normotensive pregnant women. Methods A cross-sectional observational study was conducted on 110 pregnant women, divided into two groups: 55 with PIH and 55 with normotensives. Coagulation markers such as prothrombin time (PT), activated partial thromboplastin time (aPTT), international normalised ratio (INR), and platelet count were measured. Bleeding and clotting times were also evaluated. Data were statistically analysed using student's t-test and chi-square tests, with p ≤ 0.05 considered significant. Results Women with PIH exhibited significantly lower platelet counts, PT, aPTT, and INR values compared to the normotensive group (p < 0.0001). Thrombocytopenia and prolonged bleeding time were more common in the PIH group, suggesting an increased risk of both bleeding and clotting complications. Proteinuria was observed in 32 women (58.18%) in the PIH group, reflecting the severity of the disease. Additionally, the PIH group had markedly elevated blood pressure levels. Conclusion PIH is associated with significant coagulation and haematological abnormalities, including thrombocytopenia and a hypercoagulable state, which increase the risk of thromboembolic and hemorrhagic events. Routine monitoring of coagulation profiles and haematological parameters in PIH patients is essential for timely interventions and improving maternal and fetal outcomes.

Comparative study of hematological parameters among smokers and nonsmokers in Basra city, Iraq

BackgroundHematological parameters are significantly affected by both immediate and prolonged exposure to smoking. The objective of this investigation is to evaluate the influence of cigarette smoking on hematological parameters among male students enrolled at Basrah University in Iraq. MethodsThe study comprised a total of seventy male participants, divided into two groups: smokers (n = 35) and nonsmokers (n = 35). Each participant provided a 5 ml venous blood sample to analyze the complete blood count using a hematology analyzer (Spinreact, Spincell 3). ResultsCigarette smokers exhibit notably elevated levels of Red Blood Cells (RBC) counts, Hemoglobin (HGB), Red Cell Distribution Width-CV (RDW-CV), granulocytes%, and platelets%, whereas Mean Corpuscular Volume (MCV) and lymphocytes% are notably lower among smokers. On the other hand, Hematocrit percentage (HCT), Mean Corpuscular Hemoglobin (MCH), Mean Corpuscular Hemoglobin Concentration (MCHC), and White Blood Cells (WBC) counts show no significant difference between cigarette smokers and nonsmokers. In contrast, Red Cell Distribution Width-SD (RDW-SD), Mid-range cell percentage (MID%), Mean Platelet Volume (MPV), Distribution Width (PDW), Platelet Plateletcrit percentage (PCT), Platelet-Lymphocyte Cell Ratio (P_LCR) and Platelet-Lymphocyte Cell Count (P_LCC) demonstrate no substantial variance between the two groups at the statistical significance threshold. ConclusionThis investigation concludes that tobacco cigarette smoking leads to detrimental alterations in hematological parameters, posing health risks.

A comparative study of histotripsy parameters for the treatment of fibrotic ex-vivo human benign prostatic hyperplasia tissue

Histotripsy is a noninvasive focused ultrasound therapy that mechanically fractionates tissue to create well-defined lesions. In a previous clinical pilot trial to treat benign prostatic hyperplasia (BPH), histotripsy did not result in consistent objective improvements in symptoms, potentially because of the fibrotic and mechanically tough nature of this tissue. In this study, we aimed to identify the dosage required to homogenize BPH tissue by different histotripsy modalities, including boiling histotripsy (BH) and cavitation histotripsy (CH). A method for histotripsy lesion quantification via entropy (HLQE) analysis was developed and utilized to quantify lesion area of the respective treatments. These data were correlated to changes in mechanical stiffness measured by ultrasound shear-wave elastography before and after treatment with each parameter set and dose. Time points corresponding to histologically observed complete lesions were qualitatively evaluated and quantitatively measured. For the BH treatment, complete lesions occurred with > = 30 s treatment time, with a corresponding maximum reduction in stiffness of −90.9 ± 7.2(s.d.)%. High pulse repetition frequency (PRF) CH achieved a similar reduction to that of BH at 288 s (−91.6 ± 6.0(s.d.)%), and low-PRF CH achieved a (−82.1 ± 5.1(s.d.)%) reduction in stiffness at dose > = 144 s. Receiver operating characteristic curve analysis showed that a > ~ 75% reduction in stiffness positively correlated with complete lesions observed histologically, and can provide an alternative metric to track treatment progression.

Synergistic effects on dielectric and complex impedance properties in Ti3AlC2 MAX phase‐infused PVDF‐HFP/PMMA nanocomposites

AbstractA simple solution casting technique was used to formulate films of polyvinylidenefluoride‐co‐hexafluoropropylene, polymethylmethacrylate, and Ti3AlC2 MAX phase polymer nanocomposites (PPT) with different filler content. The functional groups present in the PPT films were studied using the Fourier transform infrared spectroscopy and the nature of crystallinity was observed using X‐ray diffraction technique. The morphology of the films was studied by scanning electron microscopy. The thermal analysis was done using the thermogravimetric analysis and differential thermogravimetry analysis. The tensile behavior of the prepared films was studied from the stress‐strain graphs. The ultraviolet–visible spectra revealed their optical characteristics. The dielectric parameters of the polymer blend and nanocomposite films like dielectric constant, loss tangent, AC conductivity, and complex impedance spectroscopy with corresponding equivalent circuits were studied. A comparative study of the above parameters was done for both the polymer blend and nanocomposites to find out the advancement in the properties of the prepared nanocomposite compared with the polymer blend. The nanocomposite film having 3 wt% of Ti3AlC2 MAX phase filler loading exhibited the best properties among all the nanocomposites. The enhanced dielectric properties of the nanocomposites with mechanical and thermal resistance can be used for real‐time efficient energy storage applications.

Comparative Study of Hydrobiological Parameters Between Earthen and High-Density Polyethylene (HDPE) Brackishwater Shrimp Ponds in Ratnagiri, Maharashtra

The current study was carried out to compare the hydrobiological characteristics of a selected shrimp farm in district Ratnagiri taking pond size, stocking density and culture practices into consideration. For sampling, four earthen and four high-density polyethylene (HDPE) ponds were chosen. Most of the water parameters showed significant difference with respect to different types of ponds (earthen and HDPE) viz. temperature, pH, salinity, dissolved oxygen, alkalinity and net primary productivity (NPP) of both crops (p&lt;0.05). First crop showed significant difference among all water parameters except biochemical oxygen demand (p&lt;0.05). Second crop (January-May) showed significant difference (p&lt;0.05) among all parameters except hardness, ammonia, nitrite, gross primary productivity (GPP) and community respiration (CR). Phytoplankton showed significant difference (p&lt;0.05) with respect to different types of ponds for both crops and zooplankton showed significant differences (p&lt;0.05) only during first crop. Results indicated that high-density polyethylene (HDPE) ponds have greater consistency in water quality characteristics than earthen ponds, which could contribute to enhanced shrimp growth and survival.

Improving the performance and economics of reversible solid oxide cell-based hydrogen energy storage systems through the utilization of renewable alternative fuels

Reversible solid oxide cells (RSOCs) represent a promising solution for addressing the future challenge of large-scale renewable energy storage. However, the performance and economic viability of current RSOC systems are hindered by the large overpotential losses in electrolysis and apparent fuel (H2) costs associated with power generation. This study employs a comprehensive numerical modeling approach to analyze the potential of renewable fuel (glycerol) in assisting hydrogen production performance and reducing operating costs within RSOC systems. The detailed comparative analyses and parametric studies are conducted on H2-based and glycerol-based RSOC systems at typical operating conditions. Notably, it is found that the economic viability of hydrogen-based RSOC systems is hindered by the remarkable fuel (H2) costs during nighttime despite of the favorable effects of larger stack capacity and higher temperature. While incorporating glycerol as an alternative fuel in RSOC systems offers significant advantages, including doubling the electrolytic H2 production (from 585.92 Nm3·h−1 to 1191.24 Nm3·h−1) at a relatively low cost and substantially reducing the fuel expenses (from 594.30 $·h−1 to 30.57 $·h−1) for nighttime power generation, thus leading to competitive electrolytic hydrogen production cost (2.982 $·kg−1) and noteworthy enhancement in economic viability (LCOE of 0.090 $·kWh−1 and 0.304 $·kWh−1 for electrolysis and power generation, respectively). The findings of this study provide valuable insights that contribute to the advancement of RSOC systems, thus facilitating the development of efficient, cost-effective, and sustainable energy storage and conversion technologies.

Comparative study of spirometry parameters in chronic smokers with and without Type 2 Diabetes Mellitus (T2DM).

The study aimed to know the changes in spirometry parameters in chronic smokers and evaluate how the presence of type 2 diabetes mellitus (T2DM) affects their lung function. A prospective, cross-sectional, observational study was done for 12 months at a tertiary care hospital in the western region of Maharashtra State in India. Two groups of patients and one group of healthy volunteers aged 18 years or more were studied (with 50 in each group, n = 150). Group A consisted of smokers with T2DM, Group B- smokers without T2DM and Group 3- healthy controls who were non-smokers and non-diabetic. Spirometry was done for the following parameters: forced vital capacity (FVC), forced expiratory volume in the first second (FEV1), FEV1/FVC ratio, and peak expiratory flow (PEF) and results compared between the three groups. The mean age of the participants was 51.13 ± 10.74 years. There were 137 (91.3%) males and 13 (8.6%) females. Among the enrolled subjects, 66% had smoked for more than ten years. All spirometry parameters were significantly different across all three groups. When the spirometry parameters were compared between smokers with and without T2DM, all the parameters were significantly decreased (P < 0.05). FEV1 and FEV1/FVC were significantly decreased in T2DM patients with HbA1c >7%. The presence of T2DM in smokers significantly affects their pulmonary function tests. Uncontrolled T2DM (HbA1c >7%) can result in increased abnormality in the spirometry parameters studied. Thus, adequate glycemic control and cessation of smoking can be beneficial for the improvement of lung functions in smokers.

Investigation of optical parameters in Ge source SELBOX tunnel FET under visible spectrum

In this work, we have implemented Ge source Selective buried oxide (SELBOX) Tunnel FET for photo sensing applications in the visible range of spectrum for wavelength (λ = 300–700) nm. The various electrical parameters are extracted under dark and illumination states considering the presence and absence of trap charges at the interface of gate oxide and semiconductor. It is seen that at illumination state, the drain current degrades at low gate voltage and presence of traps lead to reduced tunnelling rate. Further, the spectral sensitivity, responsivity, and signal to noise ratio (SNR) are extracted for this TFET based photosensor with variation in λ. Result reveals that spectral sensitivity, responsivity, and signal to noise ratio (SNR) are 20.8, 0.5, and 49.5 dB, respectively, at λ = 300 nm. Further, the presence of trap charges result in degradation of these parameters. Finally, a comparative study of optical parameters with the existing data is highlighted.

Vibration Isolation and Launch Performance Enhancement of the Spacecraft In-Orbit Launch Design Using the Nonlinear Dynamic Feature

This paper proposes a new spacecraft in-orbit launch design using a nonlinear configuration to utilize nonlinear dynamics for the enhancement of vibration isolation and launch performance. The in-orbit launch device has four springs, where the stroke directions of two springs are perpendicular to the launch direction so as to produce nonlinearity with negative stiffness for enhancing the launch velocity. The other two springs are designed to counterbalance the above negative stiffness when the launch outlet is shut down, leading to quasi-zero dynamic stiffness for vibration isolation enhancement. The dynamic equations of the in-orbit launch device for both the on- and off-launch are presented. Then the performance enhancement of both the vibration isolation and launch performance is thoroughly investigated via comparative study and parametric study. The resonance peak is reduced by 4.16 dB, the effective vibration isolation bandwidth is increased by 57%, and the launch speed is increased 1.64 times. This validates the performance improvement of the new launch device design and presents a useful guideline for application.
