Patients with renal cell carcinoma have increased oxidative stress, which is effectively alleviated by curative resection. In patients with benign tumors antioxidant defense mechanisms maintain normal redox status.

CONTEXT:Spinal anaesthesia has been reported as an alternative to general anaesthesia for performing laparoscopic cholecystectomy (LC).AIMS:Study aimed to evaluate efficacy, safety and cost benefit of conducting laparoscopic cholecystectomy under spinal anaesthesia (SA) in comparison to general anaesthesia(GA)SETTINGS AND DESIGN:A prospective, randomised study conducted over a two year period at an urban, non teaching hospital.MATERIALS AND METHODS:Patients meeting inclusion criteria e randomised into two groups. Group A and Group B received general and spinal anaesthesia by standardised techniques. Both groups underwent standard four port laparoscopic cholecystectomy. Mean anaesthesia time, pneumoperitoneum time and surgery time defined primary outcome measures. Intraoperative events and post operative pain score were secondary outcome measure.STATISTICAL ANALYSIS USED:The Student t test, Pearson′s chi-square test and Fisher exact test.RESULTS:Out of 235 cases enrolled in the study, 114 cases in Group A and 110 in Group B analysed. Mean anaesthesia time appeared to be more in the GA group (49.45 vs. 40.64, P = 0.02) while pneumoperitoneum time and corresponding the total surgery time was slightly longer in the SA group. 27/117 cases who received SA experienced intraoperative events, four significant enough to convert to GA. No postoperative complications noted in either group. Pain relief significantly more in SA group in immediate post operative period (06 and 12 hours) but same as GA group at time of discharge (24 hours). No late postoperative complication or readmission noted in either group.CONCLUSION:Laparoscopic cholecystectomy done under spinal anaesthesia as a routine anaesthesia of choice is feasible and safe. Spinal anaesthesia can be recommended to be the anaesthesia technique of choice for conducting laparoscopic cholecystectomy in hospital setups in developing countries where cost factor is a major factor.

Profliferative activity in forebrain ependyma aand choroid plexus epithelium was studied in rats aged up to 42 days by means of autoradiography after injection of [3H]-thymidine. Labelling indices were higher in the lateral than in the third ventricle, while values for choroid plexus epithelium were lower than those for ependyma. In all areas examined, labelling indices showed a similar pattern of decline in the first two postnatal weeks reaching by day 12 a level about 20-30% of that on day 1. This low level, corresponding to a turnover time of 130 days for ependyma, was maintained tereafter up to day 42, indicating the persistence of proliferation in the young adult.

The purpose of this study was to compare early oncologic outcomes of oncoplastic breast surgery and conventional breast conservation surgery in patients of locally advanced breast cancer. A single-center, prospective, nonrandomized study enrolled select cases of locally advanced breast cancer (TNM T3/T4, N0/1/2) who after neoadjuvant chemotherapy, were considered for breast conservation surgery with oncoplasty techniques. The specimen volume resected, the mean margins and mean closest margin obtained were noted. The re-surgery rates, complication rates, and incidence of locoregional recurrence were also noted. Variables were compared with a retrospective cohort of similar patients who had undergone conventional breast conservation surgery. Fifty-seven patients underwent OBS (group 1) and were compared with 43 cases that had undergone conventional BCS (group 2). Majority of the patients in group 1 (73 %) had cT3 with N0 or N+ and a minority (17 %) were with limited skin involvement (cT4 and N0/N+). Relatively larger sized, post-NACT tumors could undergo OBS(4.4 vs 2.3 cm). Relatively greater proportion of tumors in central and lower quadrants were addressed by oncoplasty than traditional BCS (17/57, 29 % vs 4/43, 9 %, p = 0.04). The mean specimen volume excised in group 1 was more than that in group 2. (187.54 vs 125.19; p = 0.01). The mean of the margins were obtained more in group 1 (1.04 vs 0.69 cm); p < 0.01) as also the mean closest margin (0.86 vs 0.49 cm; p < 0.01). The incidence of close or involved margins was lesser in the OBS group (8 vs 24 %). Overall incidence of complications was similar in both groups (8/57, 14 % vs 4/43, 9 %; p = 0.34 NS). The median follow-up period of group 1 is 18 months (range 06-30 months) while group 2 is 34 months (14-44 months. There was no recurrence in group 1, but there were 5 cases (11 %) in group 2. Oncoplasty breast surgery offers more opportunity for breast conservation and oncologic safety than conventional breast conserving surgery.

The Convolutional Neural Network has amazed us with its usage on several applications. Age range estimation using CNN is emerging due to its application in myriad of areas which makes it a state-of-the-art area for research and improve the estimation accuracy. A deep CNN model is used for identification of people's age range in our proposed work. At first, we extracted only face images from image dataset using MTCNN to remove unnecessary features other than face from the image. Secondly, we used random crop technique for data augmentation to improve the model performance. We have used the concept of transfer learning in our research. A pretrained face recognition model i.e VGG-Face is used to build our model for identification of age range whose performance is evaluated on Adience Benchmark for confirming the efficacy of our work. The performance in test set outperformed existing state-of-the-art by substantial margins.

MSC occurred sporadically in donors with varied characteristics. Although we did not detect patterns to support specific changes in our acceptance criteria, certain subgroups of donors might benefit from close follow-up.
