AIM To investigate the role of genetic variants of angiotensin converting enzyme(ACE) and angiotensinogen(AGT) genes in the antiproteinuric efficacy of ACE inhibitor therapy in diabetic nephropathy(DN) *** In the present study, 270 type 2 diabetes mellitus patients with nephropathy were enrolled and treated with ACE inhibitor(ramipril) and followed at 6 mo for renal function and albumin excretion by estimating serum creatinine, end stage renal disease, and albumin/creatinine ratio(ACR) in urine. Genotyping of ACE I/D and AGT M235 T polymorphisms were performed by using primer specific polymerase chain reaction(PCR) and PCR-RFLP techniques, respectively. RESULTS Forty-eight percent of DN patients(responders) benefited with respect to proteinuria from ACE inhibitor therapy at 6 mo follow-up. A significant reduction in ACR was observed after 6 mo treatment with ACE inhibitor irrespective of whether DN patients were micro-albuminuric(≥ 30 and < 300 mg/g creatinine) or macro-albuminuric(≥ 300 mg/g creatinine) at the time of enrollment. However, macro-albuminuric patients(55%) showed better response to therapy. A reduction in urinary ACR was found independent of genotypes of ACE I/D and AGT M235 T polymorphisms although macro-albuminuric patients having TT genotype showed statistically insignificant increased response(72%). CONCLUSION ACE inhibitor therapy reduced urinary ACR by ≥ 30% in 50% of DN patients and the response is independent of ACE I/D and AGT M235 T polymorphisms.

There is a dearth of literature regarding the pregnancy outcomes in antenatal women using smokeless tobacco products (STP). Objective: To compare maternal and neonatal pregnancy outcomes in antenatal women using smokeless tobacco products with those not using tobacco products. Method: Pregnant women attending antenatal clinic at Guru Teg Bahadur hospital, Delhi received brief information about smokeless tobacco products. Antenatal women using STP and matched controls, 92 in each group (total 184) were recruited for the study. After obtaining consent, the urinary cotinine level was measured in both groups at first contact. Antenatal, labour and postpartum events were recorded in both groups. Urinary cotinine levels were again measured at 6 months in the user group. Results: Average age of antenatal women under study was 24.8 yrs and 25.21 yrs in user and non-user groups respectively. More women in the user group were illiterate (P ? 20.39 μg/ml and 24.37 +/? 20.14 μg/ml respectively (p < 0.0001). Women using STPs for more than 5 yrs recorded higher urinary cotinine levels. There was no significant difference in urinary cotinine levels with the type of tobacco product consumed. Pregnancy outcomes of 39 women are known. There was no significant difference in antenatal, intra-natal and postpartum complications in the two groups. Neonatal weight difference was 20 ***: Smokeless tobacco products are the most common forms used by women in low and middle income countries. Larger studies are required to understand their effects on pregnancy outcomes.

作者： Pravin Suryakantrao Deshmukh Kanu Megha Namita Nasare basu dev banerjee Rafat Sultana Ahmed Mahesh Pandurang Abegaonkar Ashok Kumar Tripathi Pramod Kumari Mediratta Environmental Biochemistry and Molecular Biology Laboratory Department of Biochemistry.University College of Medical Sciences & G.T.B.Hospital(University of Delhi) Department of Pharmacology University College of Medical Sciences & G.T.B.Hospital(University of Delhi) Centre for Applied Research in Electronics(CARE) Indian Institute of Technology

Objective The present study was designed to investigate the effects of subchronic low level microwave radiation （MWR） on cognitive function, heat shock protein 70 （HSP70） level and DNA damage in brain of Fischer rats. Methods Experiments were performed on male Fischer rats exposed to microwave radiation for 90 days at three different frequencies： 900, 2800, and 2450 MHz. Animals were divided into 4 groups： Group I： Sham exposed, Group I1： animals exposed to microwave radiation at 900 MHz and specific absorption rate （SAR） 5.953 x 10-4 W/kg, Group II1： animals exposed to 1800 MHz at SAR 5.835 x 20-4 W/kg and Group IV： animals exposed to 2450 MHz at SAR 6.672 x 10-4 W/kg. All the animals were tested for cognitive function using elevated plus maze and Morris water maze at the end of the exposure period and subsequently sacrificed to collect brain tissues. HSP70 levels were estimated by ELISA and DNA damage was assessed using alkaline comet assay. Results Microwave exposure at 900-2450 MHz with SAR values as mentioned above lead to decline in cognitive function, increase in HSP70 level and DNA damage in brain. Conclusion The results of the present study suggest that low level microwave exposure at frequencies 900, 2800, and 2450 MHz may lead to hazardous effects on brain.

Purpose: Fat embolism syndrome (FES) is systemic manifestation of fat emboli in the circulation seen mostly after long bone fractures. FES is considered a lethal complication of trauma. There are various case reports and series describing FES. Here we describe the clinical characteristics, management in ICU and outcome of these patients in level I trauma center in a span of 6 months. Methods: In this prospective study, analysis of all the patients with FES admitted in our polytrauma intensive care unit (ICU) of level I trauma center over a period of 6 months (from August 2017 to January 2018) was done. Demographic data, clinical features, management in ICU and outcome were analyzed. Results: We admitted 10 cases of FES. The mean age of patients was 31.2 years. The mean duration from time of injury to onset of symptoms was 56 h. All patients presented with hypoxemia and petechiae but central nervous system symptoms were present in 70% of patients. The mean duration of mechanical ventilation was 11.7 days and the mean length of ICU stay was 14.7 days. There was excellent recovery among patients with no neurological deficit. Conclusion: FES is considered a lethal complication of trauma but timely management can result in favorable outcome. FES can occur even after fixation of the fracture. Hypoxia is the most common and earliest feature of FES followed by CNS manifestations. Any patient presenting with such symptoms should raise the suspicion of FES and mandate early ICU referral.

作者： Balaram Khadka Keshav Prasad Kandel Sudikshya Pant Karan Bhatta basu dev Ghimire St. Xavier’s College Kathmandu Nepal Nepalese Center for Research in Physical Sciences (NCRPS) Kathmandu Nepal

The US Navy VLF/LF Transmitter’s NSY signal (45.9 kHz) transmitted from Niscemi, Sicily, Italy, and received at the Kiel Long Wave Monitor, Germany, was analyzed for the period of two months, May and June (EQ-month) of 2013. There were 12 earthquakes of magnitude greater than 4 that hit Italy in these two months,?of which the earthquake of 21st June having magnitude of 5.2?and a shallow focal depth of 5 km was the major one. We studied the earthquake of 21st of June 2013, which struck Tuscany,?Central Italy, (44.1713°N and?10.2082°E) at 10:33 UT, and also analyzed the effects of this earthquake on the?sub-ionos-?pheric VLF/LF signals. In addition, we also studied another earthquake, of magnitude 4.9, which hit the same place at 14:40 UT on 30th of June and had shallow focal depth of 10 km. We assessed the data using terminator time (TT) method and night time fluctuation method and found unusual changes in VLF/LF amplitudes/phases. Analysis of trend, night time dispersion, and night time fluctuation was also carried and several anomalies were detected. Most ionospheric perturbations in these parameters were found in the month?of June, from few days to few weeks prior to the earthquakes. Moreover, we filtered the possible effects due to geomagnetic storms, auroras, and solar activities?using parameters like?Dst index, AE index, and Kp index for analyzing the geomagnetic effects,?and Bz (sigma) index, sunspot numbers, and solar index F10.7 for analyzing the solar activities for the confirmation of anomalies as precursors.
