Polimorfizam gena za adiponektin (ADIPOQ) i njegova povezanost s proizvodnim i rasplodnim svojstvima indijskog mliječnog goveda

The present investigation was performed to explore the SNP in the promoter of the adiponectin (ADIPOQ) gene and its association with production and reproduction traits in Indian Sahiwal cows. A portion of the promoter (ADIPOQ) region of the ADIPOQ gene was amplified which revealed a 977 bp amplicon, and its PCR-RFLP assay with the restriction enzyme TasI revealed three genotypes, in which the CT genotype was the most frequent (62.32%), followed by CC (24.64%) and TT (13.04%). The frequency of the C and T alleles was 0.558 and 0.442, respectively. The ADIPOQ/TasI genotypes revealed a significant association with calving interval (CI) in the first and fourth lactations, in which the CC genotype showed a significantly (P<0.05) longer CI compared to the TT genotype, while in the fourth lactation the TT genotype showed a longer CI compared to the CC genotype. In the fourth lactation, the TT genotype showed a significantly (P<0.05) longer lactation period (LP) and greater total milk yield (TMY) as compared to CC and CT genotypes. In conclusion, the SNP identified in the promoter of the ADIPOQ gene and its association with production and reproduction traits suggests that this gene might serve as a candidate genetic marker for selection of dairy cattle with better milk yield. However, further studies are needed to explore these SNPs in other regions of this gene, and in other breeds and populations.Cilj ovoga rada bio je istražiti polimorfizam pojedinačnog nukleotida (SNP) u promotoru gena za adiponektin (ADIPOQ) i njegovu povezanost s proizvodnim i rasplodnim svojstvima indijskog goveda Sahiwal pasmine. Dio promotora (ADIPOQ) regije gena ADIPOQ je umnožen i prikazan produktom 977 bp, a PCR-RFLP metodom s restrikcijom enzimom TasI dobivena su tri genotipa. Među njima najčešći je bio CT genotip (62,32 %), zatim CC (24,64 %) i TT (13,04 %). Učestalost C-alela bila je 0,558, a T-alela 0,442. ADIPOQ/TasI genotipovi su pokazali znakovitu povezanost s međutelidbenim intervalom (CI) u prvoj i četvrtoj laktaciji u kojima je CC genotip pokazao znakovito duži interval između teljenja (P<0,05) u usporedbi s TT genotipom, dok je u četvrtoj laktaciji TT genotip pokazao duži interval teljenja u usporedbi s CC genotipom. U četvrtoj laktaciji TT genotip pokazao je znakovito duže trajanje laktacije (LP) (P<0,05) i ukupan prinos mlijeka (TMY) u usporedbi s CC i CT genotipovima. Zaključno, SNP identificiran u promotoru gena ADIPOQ i njegova povezanost s proizvodnim i reproduktivnim svojstvima upućuju na to da ovaj gen može poslužiti kao kandidatni genski biljeg za selekciju mliječnih krava s većim prinosom mlijeka. Potrebna su daljnja istraživanja polimorfizama pojedinačnih nukleotida u drugim regijama ovoga gena kao i u drugih pasmina i populacija

A study on trypsin, Aspergillus flavus and Bacillus sp. protease inhibitory activity in Cassia tora (L.) syn Senna tora (L.) Roxb. seed extract

<p>Abstract</p> <p>Background</p> <p>Proteases play an important role in virulence of many human, plant and insect pathogens. The proteinaceous protease inhibitors of plant origin have been reported widely from many plant species. The inhibitors may potentially be used for multiple therapeutic applications in viral, bacterial, fungal diseases and physiological disorders. In traditional Indian medicine system, <it>Cassia tora </it>(<it>Senna tora</it>) is reportedly effective in treatment of skin and gastrointestinal disorders. The present study explores the protease inhibitory activity of the above plant seeds against trypsin, <it>Aspergillus flavus </it>and <it>Bacillus </it>sp. proteases.</p> <p>Methods</p> <p>The crushed seeds of <it>Cassia tora </it>were washed thoroughly with acetone and hexane for depigmentation and defatting. The proteins were fractionated by ammonium sulphate (0-30, 30-60, 60-90%) followed by dialysis and size exclusion chromatography (SEC). The inhibitory potential of crude seed extract and most active dialyzed fraction against trypsin and proteases was established by spot test using unprocessed x-ray film and casein digestion methods, respectively. Electrophoretic analysis of most active fraction (30-60%) and SEC elutes were carried employing Sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE) and Gelatin SDS-PAGE. Inhibition of fungal spore germination was studied in the presence of dialyzed active inhibitor fraction. Standard deviation (SD) and ANOVA were employed as statistical tools.</p> <p>Results</p> <p>The crude seeds' extract displayed strong antitryptic, bacterial and fungal protease inhibitory activity on x-ray film. The seed protein fraction 30-60% was found most active for trypsin inhibition in caseinolytic assay (P < 0.001). The inhibition of caseinolytic activity of the proteases increased with increasing ratio of seed extract. The residual activity of trypsin, <it>Aspergillus flavus </it>and <it>Bacillus </it>sp. proteases remained only 4, 7 and 3.1%, respectively when proteases were incubated with 3 mg ml^-1seed protein extract for 60 min. The inhibitory activity was evident in gelatin SDS-PAGE where a major band (~17-19 kD) of protease inhibitor (PI) was detected in dialyzed and SEC elute. The conidial germination of <it>Aspergillus flavus </it>was moderately inhibited (30%) by the dialyzed seed extract.</p> <p>Conclusions</p> <p><it>Cassia tora </it>seed extract has strong protease inhibitory activity against trypsin, <it>Aspergillus flavus </it>and <it>Bacillus </it>sp. proteases. The inhibitor in <it>Cassia tora </it>may attenuate microbial proteases and also might be used as phytoprotecting agent.</p

Occurrence of chromium resistant thermotolerant coliforms in tannery effluent

1112-1116Twenty six thermotolerant strains resistant to high levels of chromium (50-250 μg/ml) were isolated from treated tannery effluent. They were also found resistant to multiple heavy metals and antibiotics. Majority of them were resistant to copper and bacitracin. Nine strains representing different resistance patterns were selected for plasmid profile and conjugation studies. Agarose gel electrophoresis results revealed that 6 strains harboured a single plasmid, whereas 3 strains exhibited 2 plasmid bands. Among antimicrobials, co-trimazole and bacitracin and among metals, Cu2+, Cd2+, Zn2+ and Ni2+ resistance were transferred most frequently at variable rates. However, chromium resistance was transferred in 6 strains with a frequency ranging 19-49×10-2. Resistance to Co2+ and Hg2+ did not transfer under environmental conditions. Among the nine strains, three were found predominantly uropathogenic Escherichia coli (UPEC) serotype 04, whereas two strains were untypable. In addition, 4 transconjugants also showed a positive result after serotyping

Metabolic syndrome & Framingham Risk Score: Observations from a coronary angiographic study in Indian patients

Background & objectives: Metabolic syndrome (MS) is an important determinant of cardiovascular (CV) risk. Framingham Risk Scores (FRS) often underestimate the CV risk in Asians, younger patients and those with MS. Asians often develop coronary artery disease (CAD) at a younger age and also have a high prevalence of MS. Only limited data are available on the relationship between MS and FRS in such patients and the present study was undertaken to report on this aspect in an Indian patient population with angiographically documented CAD. Methods: Two hundred patients undergoing coronary angiography during a three months study period were included. Diagnosis of MS was based on modified south Asian guidelines. Results: Of the 200 patients (age 56.5 ± 8.6 yr) undergoing coronary angiography, MS was diagnosed in 77 per cent n=154; abdominal obesity, low HDL and hypertension were the commonest of the diagnostic criteria of MS, being present in >70 per cent cases. Patients with MS had significantly higher mean FRS than those without MS (15.1 vs 8.65, P10%) as estimated by FRS. The proportion of patients with MS progressively increased in those with low, intermediate and high FRS (61, 87 and 92%, respectively). Though the prevalence of MS was uniformly similar (74-84%) in all age groups ( 65 yr, respectively), amongst those <45 yr, none of the patients could be categorized as having high CV risk as estimated by FRS despite having angiographic CAD, highlighting the limitation of age dependence of FRS. Interpretation & conclusions: MS is common in Indian patients with angiographically documented CAD; most patients with MS have 10-year risk of >10 per cent as estimated by FRS. Though MS is uniformly prevalent across all age groups, using the FRS may underestimate the CV risk in Indian patients despite documented CAD. These findings have significant implications for Asian patients with CAD in whom onset of CAD is often at a younger age than their Western counterparts. There should be continued health care emphasis on detection of MS and intensification of targeted preventive strategies

Comparison of different cardiovascular risk score calculators for cardiovascular risk prediction and guideline recommended statin uses

Objective: The accuracy of various 10-year cardiovascular disease (CVD) risk calculators in Indians may not be the same as in other populations. Present study was conducted to compare the various calculators for CVD risk assessment and statin eligibility according to different guidelines. Methods: Consecutive 1110 patients who presented after their first myocardial infarction were included. Their CVD risk was calculated using Framingham Risk score- Coronary heart disease (FRS-CHD), Framingham Risk Score- Cardiovascular Disease (FRS-CVD), QRISK2, Joint British Society risk calculator 3 (JBS3), American College of Cardiology/American Heart Association (ACC/AHA), atherosclerotic cardiovascular disease (ASCVD) and WHO risk charts, assuming that they had presented one day before cardiac event for risk assessment. Eligibility for statin uses was also looked into using ACC/AHA, NICE and Canadian guidelines. Results: FRS-CVD risk assessment model has performed the best as it could identify the highest number of patients (51.9%) to be at high CVD risk while WHO and ASCVD calculators have performed the worst (only 16.2% and 28.3% patients respectively were stratified into high CVD risk) considering 20% as cut off for high risk definition. QRISK2, JBS3 and FRS-CHD have performed intermediately. Using NICE, ACC/AHA and Canadian guidelines; 76%, 69% and 44.6% patients respectively were found to be eligible for statin use. Conclusion: FRS-CVD appears to be the most useful for CVD risk assessment in Indians, but the difference may be because FRS-CVD estimates risk for several additional outcomes as compared with other risk scores. For statin eligibility, however, NICE guideline use is the most appropriate

Comparison of transradial and transfemoral artery approach for percutaneous coronary angiography and angioplasty: A retrospective seven-year experience from a north Indian center

Background: With the increasing prevalence of coronary artery disease, percutaneous coronary artery procedures have become even more important. Our study has compared transradial to transfemoral artery approach for coronary procedures in Indian population. Aims and objective: Comparison of transradial and transfemoral artery approach for percutaneous coronary procedures. Material & methods: 26,238 patients, who underwent percutaneous coronary artery procedures, were divided into two groups depending upon transradial and transfemoral artery approach and compared for the various demographic and clinical characteristics, risk factors profile, vascular access and procedural details. Results: 26,238 patients underwent percutaneous coronary procedures at our center. 81% were male and 19% were female. 55.65% and 44.35% procedures were done through transfemoral and transradial approach, respectively. 17,417 (66.38%) coronary angiographies were done, out of which 53.92% were transradial and 46.08% were transfemoral procedures. 8821 (33.62%) Percutaneous Transluminal Coronary Angioplasty (PTCA) were done, out of which 25.46% and 74.54% were done through transradial and transfemoral approach, respectively. Mean fluoroscopy time was 4.40 ± 3.55 min for transradial and 3.30 ± 3.66 min for transfemoral CAG (p < 0.001). For PTCA mean fluoroscopy time was 13.53 ± 2.53 min for transradial and 12.61 ± 9.524 min for transfemoral PTCA (p < 0.001). Minor and major procedure related complications and total duration of hospital stay were lower in transradial as compared to transfemoral group. Conclusion: The number of percutaneous transradial procedures have increased significantly with reduced complication rates and comparable success rate to transfemoral approach, along with the additional benefits to patient in terms of patient comfort, preference and reduced cost of health delivery

Predictors of co-morbidities in chronic obstructive pulmonary disease patients at a tertiary care centre in north India

Background: Chronic obstructive pulmonary disease (COPD) is a common preventable and treatable disease that is characterised by persistent respiratory symptoms and airflow limitation. COPD is characterised by an intense inflammatory process in the airways, parenchyma, and pulmonary vasculature. It is possible in some cases that the inflammatory process may overflow into the systemic circulation, promoting a generalised inflammatory reaction. Patient with COPD often have concomitant chronic illness (co-morbidities). The aim of this study is to know the pattern of co-morbidities in COPD patients.Methods: This study was a cross sectional observational study conducted on 172 COPD patients (IPD and OPD) diagnosed on the basis of GOLD guideline 2017. Co morbidities were diagnosed as per standard defined criteria laid down in the respective guidelines.Results: 55.3% of the patients with COPD had co morbidities. 18/88(20.5%) patients presented with multiple co-morbidities. 49/88, 55.7% COPD patients were affected with cardiac (either only cardiac or had multiple organs affected besides cardiac), the commonest co-morbidity. Amongst cardiac, hypertension and congestive heart failure (CHF) was the commonest (n=19/49, 38.8% each) followed by CAD/CSA/IWMI/IHD/AF. Others were metabolic (n=14/88, 15.9%), GERD (n=13/88, 14.8%), Depression (n=11/88, 12.5%). Less prevalent co-morbidities were Osteoporosis (n=8/88, 9.1%), Lung cancer (n=6/88, 6.8%), Bronchiectasis (n=5/88, 5.6%) and OSA (n=3/88, 3.4%).Conclusions: Urban indwelling, advancing age and duration of illness, presentation with low mood, loss of pleasure/ interest, appetite disturbances and heart burn with relief on taking proton pump inhibitor can be predictors of co-morbidities in COPD patients. Chance of finding co-morbidities may be multifactorial. Thus, it is important to look out for co morbidities in each and every COPD patients
