Abstract
Introduction Hepatopancreatobiliary (HPB) cancers are a distinct group requiring specialized multidisciplinary care. The present study was an analysis of HPB cancers. Methods The institutional data for two years from 2017 to 2018 was retrieved from the hospital-based cancer registry (HBCR) database in Excel format (Microsoft® Corp., Redmond, WA). The demographic details, method of diagnosis, tumor characteristics, and disease extent of the patients with HPB primary sites were retrospectively analyzed. Results Out of the 1417 patients with HPB malignancies, 1193 were analyzed. Most of the patients at our center hailed from North India. The distribution of HPB cancers was as follows: hepatocellular carcinoma (HCC) (n=717, 60.1%), gallbladder (GB) (n=230, 19.3%), periampullary carcinoma (n=76, 6.37%), head of the pancreas (HOP) (n=55, 4.61%), extrahepatic bile duct (EBD) (n=53, 4.44%), intrahepatic bile duct (IBD) (n=32, 2.68%), and body of the pancreas (BOP) (n=30, 2.52%). The most common disease presentation of HPB cancers was in the seventh and sixth decades of life. Male predominance was seen in all HPB cancers except in GB with a higher incidence in females. The predominant cause of chronic liver disease (CLD) with HCC was viral-related (53.7%) with hepatitis B virus (HBV) (34.3%) higher than hepatitis C virus (HCV) (19.2%) followed by non-alcoholic fatty liver disease (NAFLD)/non-alcoholic steatohepatitis (NASH) (24.8%) and then alcohol. Adenocarcinoma was the most common morphology in pancreatobiliary malignancies. The disease presentation was locoregional in 63.4% of HCC, 69.7% of periampullary carcinoma, and 50.9% of HOP cases. The patients with EBD and IBD cancers presented commonly with locoregional disease extent in 60.4% and 62.5%, respectively. Perihilar subsite was more commonly detected (71.7%) as compared to the distal one in the patients with EBD cancers. The patients with GB cancers (GBC) presented with distant metastases in 53.5% and locoregional disease in 33%. Distant metastases were present in 76.7% of the patients with BOP cancers. The liver was a common site of distant metastases in GB, periampullary, and pancreatic cancers. Conclusions The present study highlights the characteristics and the variations in disease presentation in different primary tumor sites of HPB cancers. In view of the common locoregionally advanced disease presentation of HCC, the patients with CLD need surveillance for the early detection of lesions. As the patients with HPB cancers show advanced disease presentation, effective locoregional and systemic therapies are needed.

Abstract
Semen dilution and cryopreservation alter the homogeneity of seminal plasma, resulting in a non-physiological redox milieu and consequently poor sperm functionality. Considering the concentration-specific bimodal action of nitric oxide (NO) in the regulation of sperm functions, cryopreservation media supplemented with optimized concentrations can improve the semen attributes. The present study aimed to evaluate the effect of adding an optimized concentration of sodium nitroprusside (SNP) and N-nitro-L-arginine methyl ester (L-NAME) in an extender on in vitro semen quality. An aliquot of semen samples (n = 32) from Murrah buffalo bulls (n = 8) was divided into control (C) and treatment (T-I: SNP in extender at 1 µmol/L; T-II: L-NAME in extender at 10 µmol/L). Fresh semen quality parameters showed no significant difference at 0 h except for the structural integrity in the T-II group. Post-thaw semen quality parameters and sperm kinematics using computer-aided sperm analysis (CASA) revealed significantly higher (p < 0.05) cryoresistance in the treatment groups. Viability, acrosome integrity, and membrane integrity were significantly higher (p < 0.05) in both treatment groups; however, the results were pervasive in T-II. Lower abnormal spermatozoa were observed in both T-I and T-II. SNP supplementation led to a significant rise (p < 0.05) in NO, whereas L-NAME reduced the NO concentration in post-thawed samples, which was directly correlated with different sperm functionality and associated biomarkers viz. total antioxidant capacity (TAC) and thiobarbituric acid reactive substance (TBARS). It was concluded that the cryopreservation media supplemented with SNP and L-NAME at 1 µmol/L and 10 µmol/L, respectively, lower the cryo-damage and improve post-thaw seminal attributes.

Abstract
The present study was aimed to evaluate the effect of over dilution of semen with tris extender on motion and functional attributes of bull sperm post-thaw. Ejaculates (n = 24; mass motility ≥3+) were collected from bulls (n = 4) using artificial vagina, diluted to 20, 15, 10 and 5 million spermatozoa/0.25 ml, and cryopreserved. The results revealed that total motility (%), progressive motility (%) and rapid motility (%), straight linear velocity (μm/s), straightness (%) reduced significantly (p < 0.05) when semen was diluted to 5 million sperm concentration. Among the various sperm function attributes, proportions of live spermatozoa, acrosome intact spermatozoa, hypo-osmotic swelling responsive spermatozoa and non-capacitated spermatozoa reduced (p < 0.05) in 5 million spermatozoa, and the proportions of moribund spermatozoa, dead spermatozoa, live acrosome reacted spermatozoa, dead acrosome intact spermatozoa, capacitated spermatozoa and spermatozoa with lipid peroxidation increased significantly (p < 0.05) when semen was diluted from 20 to 5 million. However, the over-dilution of semen did not affect slow motility, dead acrosome reacted spermatozoa, sperm protamine deficiency and spermatozoa with lipid peroxidation. In conclusion, the over dilution of semen affected sperm motion and functional attributes of frozen-thawed bull semen.

Abstract
Introduction. This study aimed to analyze the degree of reduction in normal liver complication probability (NTCP) from free-breathing (FB) to breath-hold (BH) liver SBRT. The effect of the radiation dose-volume on the mean liver dose (MLD) was also analyzed due to dose prescription, normal liver volume (NLV), and PTV.Materials and Methods. Thirty-three stereotactic body radiation therapy (SBRT) cases of hepatocellular carcinoma were selected, retrospectively. For FB, the treatments were planned on average intensity projection scan (CTavg), and patient-specific internal target volume (ITV) margins were applied. To simulate the BH treatment, computed tomography (CT) scan correspond to the 40%-50% of the respiratory cycle (CT40%-50%) was chosen, and an appropriate intrafraction margin of 2 mm, 1.5 mm, and 1.5 mm were given in craniocaudal (CC), superior-inferior (SI), and lateral direction to generate the final iGTV. As per RTOG 1112, all organs at risk (OAR's) were considered during the optimization of treatment plans. NTCP was calculated using LKB fractionated model. Multivariate regression analysis was performed to see the effect of EQD2Gy, NLV, and PTV on MLD2Gy.Results.A significant dosimetric difference was observed in the normal liver (liver-ITV/iGTV). A reduction of 1.7% in NTCP was observed from FB to BH technique. The leverage of dose escalation is more in BH because MLD2Gycorresponds to 5%, 10%, 20%, and 50% NTCP was 0.099 Gy, 0.41 Gy, 1.21 Gy, and 3.432 Gy more in BH as compared to FB technique. In MVRA, the major factor which was attributed to a change in MLD2Gyis EQD2Gy. Conclusion. From FB to BH technique, a significant reduction in NTCP was observed. The dose prescription is a major factor attributed to the change in MLD2Gy. Advances in knowledge: If feasible, prefer BH treatment either for tumor dose escalation or for the reduction in NTCP.

Abstract
The present study compared the effect of mitochondria-targeted (Mitoquinone, MitoQ) and untargeted cytosolic antioxidant (Resveratrol, RESV) supplementation on lipid peroxidation (LPO) and in-vitro sperm functions of cryopreserved buffalo bull semen. To optimize additive's concentration, sperm pellet obtained from twenty-four ejaculates was supplemented with different concentrations of MitoQ (20 nM, 100 nM, 200 nM); and RESV (10 μM, 25 μM, 50 μM) against control in the extender. The post-thaw sperm motility, livability, and membrane integrity were higher (P < 0.05) in 200 nM MitoQ and 50 μM RESV than other concentrations used. In another experiment, sperm pellet from thirty-two ejaculates was supplemented with 200 nM MitoQ and 50 μM RESV in the extender. Pre-freeze and post-thaw progressive motility and livability were higher (P < 0.05) in MitoQ (200 nM) than RESV (50 μM) treatment. MitoQ supplementation improved post-thaw membrane integrity (CFDA-PI) higher (P < 0.05) than RESV, however, hypo-osmotic swelling response observed no improvement with RESV treatment. Post-thaw LPO rate was lower (P < 0.05) and Bovine cervical mucus penetration was higher (P < 0.05) in MitoQ than RESV treatment. In post-thaw semen, MitoQ showed higher (P < 0.05) proportion of acrosome intact (FITC-PNA), live non-apoptotic (P < 0.01) sperm with a higher reduction (P < 0.05) in membrane scrambling. MitoQ improved (P < 0.01) proportion of sperm with high Mitochondrial Membrane Potential and low LPO (P < 0.01) than RESV treatment. In conclusion, improvement in post-thaw in-vitro sperm functions and cryo-tolerance was more evident in MitoQ than RESV supplemented buffalo bull semen. Our study provides a better strategy to mitigate oxidative stress by enhancing mitochondrial antioxidant system with targeted antioxidants than cytosolic antioxidant supplementation.

Abstract
INTRODUCTION The impact of dose heterogeneity within the tumor on TCP and NTCP was studied using various radiobiological models. The effect of the degree of heterogeneity index (HI) on TCP was also analyzed. MATERIALS AND METHODS Thirty-seven pre-treated liver SBRT cases were included in this study. Two different kinds of treatment techniques were employed. In both arms, the prescribed dose was received by 95% of the PTV. Initially, the inhomogeneous treatment plans (IHTP) were made in which the spatial change of dose within the PTV was high and the maximum dose within the PTV can go up to 160%. Subsequently, in another arm, homogeneous treatment plans (HTP) were generated in which PTV was covered with the same prescription isodose and the maximum dose can go up to 120%. As per RTOG 1112, all organs at risk (OAR's) were considered while optimization of the treatment plans. TCP was calculated using the Niemierko and Poisson model. NTCP was calculated using the Niemierko and LKB fractionated model. RESULTS For the IHTP, TCP was decreasing as 'a' value decreased in the Niemierko model whereas, for HTP, TCP was found to be the same. NTCP of the normal liver was less in IHTP as compared to HTP, and the Niemierko model overestimates the NTCP as compared to LKB fractionated model. NTCP for all other OAR's was <1% in both kinds of treatment plans. CONCLUSION IHTP is found to be clinically better than HTP because NTCP of the normal liver was significantly less and TCP was more for certain 'a' values of the Niemierko model and the Poisson model. There is not any effect of HI on TCP was observed. Advances in knowledge: IHTP could be used clinically because of the dose-escalation and subsequently, leads to an increase in the TCP.

Abstract
BACKGROUND A purpose of the study was to investigate the dosimetric impact of contrast media on dose calculation using average 4D contrast-enhanced computed tomography (4D-CECT) and delayed 4D-CT (d4D-CT) images caused by CT simulation contrast agents for stereotactic body radiation therapy (SBRT) of liver cases. MATERIALS AND METHODS Fifteen patients of liver SBRT treated using the volumetric modulated arc therapy (VMAT) technique were selected retrospectively. 4D-CECT, and d4D-CT were acquired with the Anzai gating system and GE CT. For all patients, gross target volume (GTV) was contoured on the ten phases after rigid registration of both the contrast and delayed scans and merged to generate internal target volume (ITV) on average CT images. Region of interest (ROI) was drawn on contrast images and then copied to the delayed images after rigid registration of two average CT datasets. The treatment plans were generated for contrast enhanced average CT, delayed average CT and contrast enhanced average CT with electron density of the heart overridden. RESULTS No significant dosimetric difference was observed in plans parameters (mean HU value of the liver, total monitor units, total control points, degree of modulation and average segment area) except mean HU value of the aorta amongst the three arms. All the OARs were evaluated and resulted in statistically insignificant variation (p > 0.05) using one way ANOVA analysis. CONCLUSIONS Contrast enhanced 4D-CT is advantageous in accurate delineation of tumors and assessing accurate ITV. The treatment plans generated on average 4D-CECT and average d4D-CT have a clinically insignificant effect on dosimetric parameters.

Abstract
Objective:The development of a stringent derivative-based gamma (DBG) index for patient-specific QA in stereotactic radiotherapy treatment planning (SRTP) to account for the spatial change in dose.Methods:Twenty-five patients of liver SBRT were selected retrospectively for this study. Deliberately, two different kinds of treatment planning approaches were used for each patient. Firstly, the treatment plans were generated using a conventional treatment planning (CTP) approach in which the target was covered with a homogeneous dose along with the nominal dose fall-off around the treatment field. Subsequently, the other treatment plans were generated using an SRTP approach with the intent of heterogeneous dose within the target region along with a steeper dose gradient outside the treatment field as much as possible. For both kinds of treatment plans, two dimensional (2D) conventional gamma (CG) and DBG analysis were performed using the 2D ion chamber array and radiochromic film.Results:Difference in the DBG index was statistically significant whereas, for CG analysis, the difference in CG index was insignificant for both types of treatment plans (CTP and SRTP). A significant positive correlation was observed between the difference in the DBG index and the difference in HI for high gamma criteria.Conclusion:The DBG evaluation is found to be more rigorous, and sensitive to the only SRTP. The proposed method could be opted-in the routine clinical practice in addition to CG.Advances in knowledge:DBG is more sensitive to detect the spatial change of dose, especially in high dose gradient regions.

Abstract
The present study explored the effect of anandamide supplementation in the extender on quality of low sperm doses during cryopreservation in Sahiwal bulls. Each fresh semen sample was split into eight aliquots (I, II, III, IV, V, VI, VII and VIII). The aliquots I, II, III and IV were taken as control and diluted to 20, 15, 10 and 5 million spermatozoa/0.25 ml respectively. The aliquots V, VI, VII and VIII were diluted with extender (supplemented with anandamide at 1 µM/ml of extender) to 20, 15, 10 and 5 million spermatozoa/0.25 ml respectively. This was followed by filling of diluted semen into French mini straws, equilibrated at 4°C of 4 hr and cryopreserved. The results revealed that the proportions of motile spermatozoa, live spermatozoa and live acrosome intact spermatozoa were significantly (p < .05) higher in all anandamide-treated sperm doses compared to control. The proportions of moribund spermatozoa, dead acrosome intact spermatozoa and capacitated spermatozoa were significantly (p < .05) reduced in all anandamide-treated sperm doses compared to control, with no difference in proportion of dead acrosome-reacted spermatozoa. In conclusion, anandamide supplementation in the extender increases the post-thaw quality of low sperm doses during cryopreservation in bulls.

Abstract
Downy mildew (DM) caused by Sclerospora graminicola is the most calamitous disease of pearl millet. Therefore, for introgression of DM resistance (DMR) in HHB 197 (MH-1302), an elite pearl millet hybrid, a marker-assisted breeding was undertaken by targeting three DMR loci on linkage groups (LGs) 1, 2 and 4. Breeding programme was initiated by crossing HBL 11 (DM susceptible), male parent of HHB 197 hybrid with ICMP 451 (DM-resistant) to produce true F1 plants. By conducting three rounds of backcrossing and selection, BC3F1 lines were generated. Foreground selection was employed using six polymorphic simple sequence repeat (SSR) markers of the 18 total selected markers. Four of these markers were linked to LG 1, five to LG 2 and nine to LG 4. Background selection was performed in BC3F1 generation using 33 polymorphic SSR markers of a total of 56 evenly spread SSR markers in the pearl millet genome to check recovery of recurrent parent genome. On the basis of genotypic selection (foreground as well as background) using selected SSR markers, agronomic performance in field and DM screening in greenhouse; 10 improved HBL 11 lines were selected and crossed with ICMA 97111 to produce DM-resistant HHB 197 hybrid versions. Six putatively improved HHB 197 hybrids were successfully tested in first year trials at Hisar and Bawal locations of Haryana and two selected versions with higher yield and zero DM incidence will be further tested in multilocation trials.

Abstract
BACKGROUND The membrane and acrosomal integrity of sperm play a vital role in fertilization process; however they are compromised upon cryopreservation. OBJECTIVE To study the effect of cholesterol-loaded cyclodextrin (CLC) on membrane and acrosome status of Hariana bull sperm during cryopreservation. MATERIALS AND METHODS Semen samples collected from Hariana bulls with mass motility ≥ 3+ and individual progressive motility ≥ 70% were utilized in the study. Each ejaculate was split into two parts, one part being evaluated freshly for various seminal attributes and the other part being diluted in Tris diluent (without egg yolk and glycerol) to obtain a final concentration of 120×106 sperm/mL. The diluted semen was divided into four treatments: Group I, without CLC (control); Group II, with CLC at 0.5 mg per 120 million sperm; Group III, at 1.0 mg per 120 million sperm; Group IV, at 2.0 mg per 120 million sperm. All aliquots were incubated for 15 min at 37°C and each sample was diluted with Egg yolk-Tris-Glycerol (EYTG) extender up to 80×106 sperm/mL. The diluted semen samples were packed in French mini straws (0.25 mL), sealed and equilibrated at 4°C for 4 h followed by cryopreservation. The samples at pre-freeze and post-thaw stage were evaluated for membrane and acrosomal integrity, as well as primary, secondary and tertiary acrosomal damages. RESULTS The membrane and acrosomal integrity was significantly higher in group II as compared to groups I, III, and IV, at pre-freeze and post-thaw stage (P<0.05). The primary and secondary acrosomal damage were significantly reduced in group II compared to other groups (P<0.05). No significant difference in tertiary acrosomal damage was found among different groups. CONCLUSION CLC improves the membrane and acrosomal integrity, and reduces primary and secondary acrosomal damages during cryopreservation of Hariana bull sperm.
