Coronary artery dimensions as determined by intravascular ultrasound in an indian population

Background: Percutaneous coronary intervention (PCI) has remained one of the greatest treatment modalities of the spectrum of atherosclerotic coronary artery disease over the past few years due to its high efficacy and minimal invasiveness. The most common cause of stent failure is stenting under-expansion, which complicates PCI. Thus, it is tremendously important to perform PCI relying on the precise measurement of the size of the coronary artery obtained with the help of intracoronary imaging. There is limited data on the size of coronary arteries as measured by intravascular ultrasound (IVUS) in India and specifically in southern India. This study, conducted between January 2022 and March 2023, aimed to estimate the coronary artery dimensions, which can serve as a guide to PCI when intracoronary imaging is not available Methods: A sample size of 165 patients with proven coronary artery disease undergoing IVUSguided PCI during acute or chronic coronary syndrome were recruited, and coronary arterydimensions were measured in this research work. The mean arterial size and predictors of the arteries were reviewed. Results: A total of 165 patients with 590 coronary artery segments were recruited: the mean left main (LM), external elastic membrane (EEM) diameter, and cross-sectional area (CSA) were 4.92 ± 0.41 mm and 17.83 ± 2.88 mm2 proximal left anterior descending (LAD) artery, 3.75 ± 0.32 mm and 13.74 ± 2.45 mm2 the mid-LAD 3.42 + 0.28 mm and 10.65 + 2.08 mm2 the distal LAD 2.94 + 0.31 mm and 7.98 + 2.07 mm2 the proximal left circumflex artery (LCX) 3.62 ± 0.32 mm and 11.67 ± 2.36mm2, the distal LCX 2.91 ± 0. 33 mm and 8.98 ± 2.22mm2 the proximal right coronary artery (RCA) 4.17 ± 0.41 mm and 14.82 ± 2.78 mm2 the mid-RCA 3.85 ± 0.36 mm and 12.94 ± 2.44 mm2, the distal RCA 3.43 ± 0.30 mm and 11.08 ± 2.05 mm2, respectively. The predictor of most epicardial coronary arteries is body surface area (BSA) with positive linear correlation. Conclusions: Measurements of the coronary arteries obtained were comparable to the previous data on coronary artery size of Southeast Asia and Caucasian populations using IVUS. BSA is an independent predictor for the majority of epicardial coronary arteries with a positive linear relationship. Male gender and hypertension also positively correlate with larger coronary artery dimensions, while dyslipidemia leads to smaller coronary artery sizes. Neither diabetes nor smoking influences coronary artery size in the current study. Finally, the quantification of the size of the coronary artery will help the clinician to have a reference dimension in instances where there is no intravascular imaging available.

Post-merger profitability of selected banks in india

The present study aims to shed some light on the gains from consolidation exercise in terms of profitability of banks. Through the application of paired t-test, we arrived at the result that the consolidation of banks did improve the profitability of banks in India. The increase in profitability of banks under study is due to an increase in employee turnover and the subsequent reduction in operating expenses. Merger and acquisition programmes in Indian banks cannot be regarded as a false step if the benefits of it accrue to all stakeholders.

Comparative energy scheduling and efficiency analysis of 150kw hybrid micro-grids using ann-pso

This study investigated the formulation, implementation, and performance implications of an artificial neural network–particle swarm optimization (ANN–PSO) based energy scheduling framework for a 150kW hybrid micro-grid. The analysis focused on two hybrid configurations, namely micro gas turbine–fuel cell (MGT–FC) and solar photovoltaic–battery storage system (PV–BSS), with emphasis on optimal dispatch behaviour and system efficiency under dynamic load and generation conditions. MATLAB was used to simulate ANN-based forecasting of hourly load and distributed energy resource outputs, which were subsequently optimized using PSO over multiple iterations to achieve balanced supply–demand scheduling. 4-in-1 visualization techniques were employed to capture convergence behaviour, transient response, dispatch stability, and efficiency dynamics across operating scenarios. Results showed that both hybrid systems achieved convergence within 20–24 PSO iterations, with scheduled power maintained within 50–120kW despite injected disturbances of ±20–30kW. The MGT–FC configuration demonstrated smoother dispatch profiles and faster fitness convergence, while the PV–BSS system exhibited greater variability due to intermittency, compensated by storage dispatch. Efficiency analysis revealed that optimal ANN–PSO scheduling sustained MGT–FC efficiency within 83–89%, whereas PV–BSS efficiency ranged between 41–72%, peaking during high-irradiance periods. Overall, the findings established that ANN–PSO-based scheduling enhanced operational stability and efficiency in both configurations, while highlighting the superior resilience of the MGT–FC hybrid under identical dynamic conditions. The study concluded that intelligent optimization provides a viable pathway for improving micro-grid performance in developing communities and industrial off-grid applications, where reliable and efficient decentralized power supply remains critical. It was therefore recommended among others that power system engineers and industrial energy planners in developing economies adopt ANN–PSO frameworks for real-time micro-grid dispatch to improve efficiency, resilience, and adaptability of decentralized energy systems serving communities and industrial loads.

Evaluating the effects of insulin, metformin and glibenclamide on the pups’ prefrontal cortex and oxidative stress markers of streptozotocin-induced diabetic pregnant rats

There is an upsurge in gestational diabetes mellitus with many devastating consequences for the mother and developing fetus. Insulin therapy remains a mainstay. However, insulin is expensive and comes with the pain of multiple injections. Therefore, there is a need to explore commonly administered oral hypoglycemic agents to cater for the increasing gestational diabetes mellitus-associated neurological complications. This study assesses the effects of glibenclamide, metformin and insulin on the pups’ prefrontal cortex in diabetic pregnant rats. 35 sexually matured adult female rats weighing between 120 g and 160 g were used and assigned into five groups (A to E) of seven rats each group. Diabetes was induced by streptozotocin (45 mg/kg and 35 mg/kg; ip). Hyperglycemic rats were treated with insulin (1.0 UI daily), metformin (200 mg/kg/day) and glibenclamide (0.6 mg/kg/day). Body weight and blood glucose levels were evaluated. Rats were sacrificed at 18-day gestation, the pups were harvested, and their brains were processed for tissue oxidative stress markers and various histological examinations. Glibenclamide and metformin caused a significant blood glucose reduction at 37.9% and 40.7%, respectively, compared to the insulin group (33.09%). There was no significant difference in the body-organ ratio in rats treated with metformin when compared to rats treated with insulin. Metformin and glibenclamide had a significant increase in tissue glutathione reductase and a decrease in malondialdehyde compared with insulin and diabetic control groups. The pups’ prefrontal cortex showed degenerated neuronal cells in the diabetic control animals. The diabetic rats treated with metformin and glibenclamide showed improved pyramidal neurons compared with diabetic and insulin groups. This study suggests that metformin and glibenclamide glycemic control may prevent and improve antioxidant enzymes and reverse some neurotoxic effects caused by streptozotocin-induced diabetes in rats.

Physicochemical properties and permeation across mouse skin of non-steroidal anti-inflammatory drugs

The skin provides an effective barrier and only limited number of drugs can penetrate in adequate amounts. This study aims to identify the relationship between the physicochemical properties and permeation across mouse skin of non-steroidal anti-inflammatory drugs in view of their feasibility to transdermal delivery. Biphenylacetic acid, diclofenac base, diclofenac sodium, indomethacin and piroxicam are the drugs studied. Number of physicochemical properties studies were performed. Drug permeation studies across hairless mouse skin were carried out using an in-vitro finite dosing diffusion cell. The relationship between physicochemical properties of the drugs studied and their percutaneous penetration was studied. Purity for the compounds studied ranged from 99.09% to 100% in which 99.89% purity was obtained for diclofenac base. At 7.4, the % ionized of piroxicam was found to be 95.12%, while for other drugs were in the range of 98.01% and 99.96%. The true partition coefficient values in the n-octanol/water system are in the range of 1.85 and 2.85, while in the n-octanol/phosphate system ranged from 2.14 to 3.70. Observed solubility in water, phosphate buffer and n-octanol ranged from 0.033 to 0.322, 0.202 to 0.329 mg per ml, and 2.19 to 16.10 mg per ml, respectively. A linear relationship was found between water solubility and melting point between steady-state rates of permeation across intact and viable skin, between n-octanol solubility and maximum predicted flux and between molecular volume and the ratio of maximum predicted flux. Predicted flux calculated was compared with the experimental data which resulted in a high correlation. Physicochemical criteria which were determined the feasibility of non-steroidal anti-inflammatory drugs studied for transdermal delivery were identified. The relationships obtained in this study provide an essential physical and chemical properties that govern transport of non-steroidal anti-inflammatory drugs across hairless mouse skin.

Evaluation of quality attributes of noodles produced from blends of acha, adu, mungbean and moringa oleifera composite flours

This study aimed at the evaluation of the quality attributes and sensory properties of noodles produced from composite blends of acha, adu, mungbean and moringa oleifera seed. Composite flours of acha, adu, mungbean and moringa oleifera seed were formulated by total replacement of wheat with acha, adu, mungbean and moringa oleifera seed at different graded ratios (B= (55:35:5:5), C= (55:30:10:5, D= (50:30:15:5), E= (50:25:20:5), F= (45:25:25:5) while 100% wheat flour was used as the control (sample A)). The composite flours were used to produce noodles and the noodles subjected to proximate analysis and sensory properties evaluation. Proximate analysis revealed that the noodles contained moisture content of 10.22-13.90%, 2.32-4.48% ash, 10.13-17.90% protein, 1.50-5.71% lipid, 0.48-3.68% crude fibre, 54.33-75.35% carbohydrate and 340.31-355.42Kcal/100 g energy. There was an increase in the moisture, ash, protein, lipid and crude fibre contents with a decrease in carbohydrate and energy contents as the amount of mungbean flour increases. Sensory evaluation scores showed that noodles made with 0% wheat, 55% acha, 35% adu, 5% mungbean and 5% moringa oleifera seed can favourably compare with the control. It is recommended that the beany flavour of mung beans be removed before its addition in the composite blend in order to produce noodles that can be highly accepted.

First report of post-vomiting subcutaneous peri-lacrimal drainage system emphysema

Subcutaneous emphysema is defined as a trapped air in tissues under the skin. This entity most often occurs in the chest wall and neck but can infrequently happen in other parts of the body like the orbital area [1]. The main mechanism of subcutaneous emphysema is the traumatic damage of the anatomical air-filled cavities or canals. Most of the rare, reported cases of orbital and periorbital emphysema were described in adults as complications of several types of traumas, including direct trauma, recent or previous surgery [2,3], barotrauma secondary to non-invasive ventilation, such as continuous positive airway pressure therapy [4], and even post forceful noseblowing [5]. In this report, we described the first reported case of post-vomiting subcutaneous emphysema surrounding the medial canthus of the right eye in a 10-year-old boy.

Acoustical performance of a double-expansion chamber muffler: design and evaluation

Background: Exhaust noise is known to be a major pollutant in the environment and workplaces due to the development of industry and transportation. Exhaust noise can be reduced to normal levels by mufflers or silencers. A reactive muffler efficiently dampens noise at low frequencies by reflecting sound waves. Therefore, muffler design is of great importance in exhaust noise reduction. Transmission loss (TL) is an essential characteristic of mufflers, demonstrating their acoustical properties. Any acoustical appliance is selected based on its damping performance and reliability. Predicting TL through experimentation is different from theoretical calculations. Methods: In the present study, a double-expansion chamber muffler was designed as a reflective muffler on a laboratory scale by equations. Next, TL was evaluated by an impedance tube applying a 4-microphone technique to determine the acoustical performance of the designed muffler. Results: Findings revealed that the TL of the muffler at 312 Hz frequency obtained 27.5 dB agreement with the required TL of the muffler of 25 dB. In addition, the TL of the muffler against frequency attenuates noise in broadband frequencies. Conclusions: These results indicated that the built muffler provides desired TL for exhaust chambers. Therefore, equations can be used as a precise method for muffler design. Furthermore, multi-expansion chamber mufflers are useful for reducing noise at a wide range of frequencies.

Multidisciplinary residential treatment of type 1 diabetes mellitus and co-occurring eating disorders

Research on treatment for diabetes and co-occurring eating disorders is sparse. We examined outcomes from multidisciplinary residential treatment for women with type 1 diabetes and eating disorders and the impact of treatment duration on outcomes. Participants were 29 women with type 1 diabetes and eating disorders receiving residential treatment. Repeated measures analyses of variance examined changes in blood glucose and psychological symptoms over treatment. Analyses were repeated to include treatment by duration interactions. Treatment produced significant reductions in blood glucose, eating disorder symptoms, and psychological concerns. Longer treatment duration was associated with greater improvements in psychological symptoms. Disordered eating is alarmingly common among individuals with type 1 diabetes mellitus, with rates of co-occurring diabetes and eating disorders estimated as high as 40% (Young etal., 2012; Young-Hyman & Davis, 2012). The most commonly noted link between type 1 diabetes and eating disorders is in the form of purging through insulin omission for weight loss purposes (Darbar & Mokha, 2008), which has been noted for individuals with diabetes co- occurring with anorexia nervosa (AN), bulimia nervosa (BN), and eating disorder not otherwise specified (EDNOS; Nielsen, 2002; Peveler & Fairburn, 1989). However, even among individuals with diabetes who do not omit insulin, eating disorder symptoms are elevated (Jones, Lawson, Daneman, Olmsted, & Rodin, 2000).

Two decades of recurrent granuloma, due to foreign body in the scalp, mimicking bone tumor

Foreign bodies (FBs) in the scalp are a common incident following head trauma, especially in traffic accidents, and are detected in the early post-traumatic period. The persistence of these FBs may cause pain and paresthesia. We report a case of 41 years old man, whose victim it’s been 20 years of physical aggression, in which the victim was hit by a brick occasioning a frontal wound stitched at the time without sufficient exploration. Months later, the patient presented several episodes of a frontal scalp nodular lesion with pus leakage (Fig. 1). The lesions were only treated with local antibacterial agents. Four years before the patient consults at our level, he consulted a dermatologist who performed a removal of the skin lesion. Months later, the lesion reappeared. At our level the clinical examination suspected a bone lesion, so CT was performed. Brain imaging was strongly evoking bone tumors or osteitis (Fig. 2). The patient was operated on under general anesthesia. First, a carcinogenic removal of the scalp lesion was performed; then, when reaching the bone, hard red friable bodies well separated from proportionally healthy bone were found. Those findings raise suspicion of the presence of FBs nested in the bone from the first head trauma. Hence, a carcinologic removal of the affected bone was postponed, and simple curettage was performed (Fig. 3). The post-operative course was without complications. The histological study confirmed per-operative findings: Multiple stony FBs associated with inflammatory reaction especially lymphocytes around vessels and the FBs.

Forecasting industrial ph levels: comparative study of sarima, regression trees and control chart diagnostics

Implementation of Statistical Process Control (SPC) techniques in food and beverage industry are crucial to deliver consumable product that meets customer expectations. This study investigated industrial pH forecasting and process stability in a syrup manufacturing facility. We analyzed 1,247 pH observations with three objectives: (1) Quantify instability via control charts, (2) Model pH dynamics using Seasonal Autoregressive Integrated Moving Average (SARIMA) and Classification And Regression Trees (CART), and (3) Develop diagnostic frameworks for unstable processes. Methodologically, Exponentially Weighted Moving Average (EWMA) charts assessed stability; Box-Cox transformed SARIMA (λ=2) with seasonal differencing was used for forecasting; CART identified variable importance. Control charts revealed profound instability: 83.3% of points violated 3σ limits; run tests significant (p<0.001). For SARIMA, (1,0,1)(0,1,1)₁₂ achieved significant parameters (p<0.0001) with improved residual diagnostics versus non-seasonal ARIMA, though minor autocorrelation remained at lag 12 (p=0.003). CART explained training R²=18.86% and test R²=17.93% of pH variation, identifying filling weight and sodium benzoate as key predictors. Crucially, this study demonstrates that forecasting retains diagnostic utility even in unstable environments: SARIMA residuals provide seasonal fingerprints of assignable causes, while CART thresholds guide intervention priorities. SARIMA(1,0,1)(0,1,1)₁₂ demonstrated superior residual properties: eliminated back forecast warnings (present in ARIMA), reduced autocorrelation at lag 24 (p=0.017 vs 0.040), and explicitly modeled 12-period seasonality. While process instability persists, SARIMA provides diagnostic fingerprints of assignable causes through seasonal parameters (SMA₁₂=0.9846, T=513.12) and residual patterns. We conclude that SARIMA offers enhanced short-term forecasting capability, but process intervention remains essential for reliability. The study advocates for integrated instability-informed forecasting combining SARIMA diagnostics, real-time control charts, and expanded sensor deployment.

Comparative growth of jipe tilapia, oreochromis jipe and nile tilapia, oreochromis niloticus using regression modeling

Regression modeling analyses the relationship between two or more variables and can be used to predict the response variable from one or more independent variables. The present study uses linear regression analysis to evaluate the growth in the two fish species of genus Oreochromis, Nile tilapia and Jipe tilapia, under aquaculture conditions. The models were fitted using a collection of functions in the R-software library. The final models were selected using the goodness of fit criteria based on the coefficient of differentiation, the model p- values and Akaike information criteria. The significance of the linear relationship between predictor variables and the mean response was tested by comparing the computed standardized parameter estimates, whereas the confidence intervals were constructed to assess the uncertainty of predicting the response variable and determine outliers in the model. Generally, both species exhibited good condition during growth and all the measured water quality variables significantly afffected growth (p<0.05). However, only temperature and dissolved oxygen produced the most important linear relationship with fish weight. The study recommends that data from a controlled experiment should be used the determine the interactions between the two growth variables.
