Mukherjee Soumya Patra Arindam Pande rana Rathor roy Debopriyo Mondal Ashesh Halder Sumit Shanker Medica Superspecialty Hospital 127 Eastern Metropolitan Bypass Nitai Nagar Mukundapur Kolkata West Bengal India North Eastern Indira Gandhi Regional Institute of Health & Medical Sciences (NEIGRIHMS) Mawdiangdiang Shillong Meghalaya India

Background: Bifurcation lesions pose a high risk for adverse events after percutaneous coronary intervention (PCI). Evidence supporting the benefits of the two-stent strategy (2SS) for treating coronary bifurcation lesions in India is limited. This study aimed to evaluate the clinical outcomes of various 2SSs for percutaneous transluminal coronary angioplasty for bifurcation lesions in India. Materials and Methods: This retrospective, observational, multicentric, real-world study included 64 patients over 8 years. Data on demographics, medical history, PCI procedures, and outcomes were recorded. Descriptive statistics were computed using the SPSS software. Results: Patients (n = 64) had an average age of 65.3 ± 11.1 years, with 78.1% males. Acute coronary syndrome was reported in 18.8%, chronic stable angina in 40.6%, and unstable angina in 34.4% of participants. Two-vessel disease was observed in 98.4% of patients, and 99.4% had true bifurcation lesions. The commonly involved vessels were the left anterior descending artery (50%), left circumflex coronary artery (34.4%), and first diagonal artery (43.8%). Mean percent diameter stenosis was 87.2% ± 10.1%. The mean number of stents used was 2.00 ± 0.34. The 2SS techniques included the T and small protrusion (TAP) (39.1%), double kissing (DK) crush (18.8%), and the culotte techniques (14.1%). Procedural and angiographic success rate was 92.18%. Major adverse cardiovascular events at 1-year follow-up occurred in 7.8% of cases. Conclusion: The 2SS for bifurcation lesions showed favorable in-hospital and follow-up outcomes. Findings can serve as a resource for bifurcation angioplasty in India. Larger real-world studies with robust methodology are needed to validate these results.

In Vitro Antioxidant and Radio Protective Activities of Lycopene from Tomato Extract against Radiation—Induced DNA Aberration

引用

Journal of Biosciences and Medicines 2024年第2期12卷 202-213页

作者： Safaiatul Islam Abu Hena Mostofa Kamal Md. Ziaur Rahman Protul Kumar roy A.Y.K. Md. Masud rana Molecular Radiobiology and Biodosimetry Division Institute of Food and Radiation Biology Bangladesh Atomic Energy Commission Savar Bangladesh

Background: The accumulation of free radicals is linked to a number of diseases. Free radicals can be scavenged by antioxidants and reduce their harmful effects. It is therefore essential to look for naturally occurring antioxidants that come from plants, as synthetic antioxidants are toxic, carcinogenic and problematic for the environment. Lycopene is one of the carotenoids, a pigment that dissolves in fat and has antioxidant properties. Materials and Methods: The antioxidant and free radical scavenging activity were assessed using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay. The impact of lycopene on bacteria (E. coli) susceptibility to γ-radiation was examined by radio sensitivity assay. The study also examined the induction of strand breaks in plasmid pUC19 DNA and how lycopene extract protected the DNA from γ-radiation in vitro. Results: At varying concentrations, lycopene demonstrated its ability to scavenge free radicals such as 2, 2-diphenyl-1-picrylhydrazyl (DPPH). IC50 for lycopene was determined at 112 μg/mL which was almost partial to IC50 of standard antioxidant L-ascorbic acid. The D10 value 180 Gy of E. coli was found to be >2-fold higher in the extract-containing lycopene sample than in the extract-free controls. The lycopene extracts inhibited the radiation-induced deterioration of the plasmid pUC19 DNA. At an IC50 concentration, lycopene provided the highest level of protection. Conclusion: Lycopene functions as an efficient free radical scavenger and possible natural antioxidant source. For cancer patients and others who frequently expose themselves to radiation, lycopene may be a useful plant-based pharmaceutical product for treating a variety of diseases caused by free radicals.

A middle aged, non-addict male presented with right upper abdominal pain and swelling with respiratory distress. Examination revealed central cyanosis, bipedal pitting edema with prominent epigastric and back veins. Liver was enlarged, tender, spanned 20 cm without any splenomegaly or ascites. Other systems were clinically normal. Laboratory investigations showed polymorphonuclear leucocytosis with slightly deranged liver function. Abdominal ultrasonography showed an abscess in the right lobe of the liver with compressed inferior vena cava （IVC）, middle and left hepatic veins. Arterial blood gas （ABG） documented hypoxia with orthodeoxia and air-contrast echocardiography was suggestive of an intrapulmonary shunt. A diagnosis of hepato-pulmonary syndrome （HPS） was made with near normal liver function secondary to amebic liver abscess. It reversed completely following successful treatment of the liver abscess.

This research was aimed to study the physicochemical properties and antioxidant activity of biscuits fortified with red kidney bean (Phaseolus vulgaris) powder. Proximate compositions, total phenol content, antioxidant activity, and functional properties of red kidney bean (RKB) powder were studied before and after the incorporation of red kidney bean in the biscuits. The bean powder was mixed with wheat flour at a level of 0% as control, 10%, 20%, and 30% during dough preparation. Results revealed that RKB powder is a rich source of protein (26.25%) together with carbohydrate (59.7%), fat (2.4%), and ash (3.27%). The total phenolic content of bean powder was 14.15 mg GAE/g. Kidney bean powder showed good functional properties including water absorption capacity (149.7%), oil holding capacity (99.54%), swelling capacity (4.6%), and bulk density of 0.74 g/ml. After increasing the percentage of RKB with control, there were significant increases (p < 0.05) in the levels of protein, moisture, ash, fat, while carbohydrate content and total gross energy decreased significantly. Investigation of total phenolic content showed the increasing trend with the higher RKB fortification, which amounted to 10.31 mg GAE/g for control and 12.50 mg GAE/g for 30% RKB. DPPH radical scavenging activity was investigated for all the samples at five different concentrations. As there was an increase in the percentage of RKB and concentration of the samples, the antioxidant activity also increased significantly (p < 0.05), where IC50 value decreased from 0.0228 mg/ml for control to 0.0289 mg/ml for 10% RKB, followed by 20% and 30% RKB, respectively. In sensory test, the control cake secured the highest score in color, f

Radiation Absorption and Variable Electrical Conductivity Effect on High Speed MHD Free Convective Flow past an Exponential Accelerated Inclined Plate

引用

World Journal of Mechanics 2017年第8期7卷 211-241页

作者： B. M. Jewel rana Raju roy Lasker Ershad Ali S. F. Ahmmed Mathematics Discipline Khulna University Khulna Bangladesh

The effects of variable electrical conductivity and radiation absorption on high-speed MHD (Magnetohydrodynamics) free convective flow past an exponential accelerated inclined plate with higher order chemical reaction have been investigated. The electrical conductivity has been considered as a function of temperature. The chemical reaction has also been considered as the higher order. The usual transformations have been used to obtain the coupled dimensionless momentum, energy and concentration equations. Then the obtained non-dimensional partial differential equations have been solved numerically by explicit finite difference method. For excellent accuracy, stability and convergence test have been carried out. A computer program Compaq Visual FORTRAN 6.6a has been used to calculate the numerical results. The obtained numerical results concerned with the fluid velocity, temperature, concentration, concerned with skin friction, Nusselt number, Sherwood number, streamlines and isotherms are imprinted graphically by Tecplot and discussed in details. It is noticed that increasing of magnetic parameter increases the temperature and decreases the velocity, skin friction and Nusselt number. It is also observed that the temperature profile is increasing with the increasing values of Dufour number. However, the order of the chemical reaction increases the concentration profile.

目前,在印度由核盘菌引起的芥菜腐烂变的很严重,其他地方也有很高的疾病突发率,产量下降直接导致种植者的积极性下降。据报道,病原菌感染大约400多种植物,且至今没有发现并证实在任何宿主中有抵抗这类疾病数据报告。本试验在农场的中心[77°27′E,27°12′N,海拔160m,具有很厚很肥沃的淤积层土壤,pH8.0]进行,一块5m×4.8m的土地被随机划分成30cm×10cm大小的小区,并设计4个重复,3个日期播种(07,28Oct,18Nov2006)用测试Rohini多样性来了解疾病发生时不同非生物因素的影响。每周通过重量分析方法对每块地进行湿度分析并记录数据。在花期每天08:00-10:00收集花瓣,并且把他们放在含有氯霉素的马铃薯葡萄糖琼脂培养基上培养,以记录印度芥菜花瓣上菌核病的孢子数量.气候因素有:最高和最低温度,上午和下午的相对湿度,以及在离试验地点200m远的气象台观察到的日照长度。数据分析显示:花瓣病原菌孢子的感染数量与光照时间成正相关(R2=0.97)。菌核病导致的腐烂范围与土壤的相对湿度成正相关(R2=0.84),特别是在开花季节和播种后的500天。在苗期500天的临界期,凉爽而干净的天气与高湿度的土壤似乎使试验地的印度芥菜上菌核病发生率更高。
