Background: Wistar rats are extensively used as the model for assessing toxicity and efficacy in preclinical research. Hematological and biochemical laboratory data are essential for evaluating specific variations in the physiological and functional profile of a laboratory animal. Establishing hematological and biochemical reference values for Wistar (han) rats at various age intervals was the goal of this work. Male and female Wistar rats (n = 660) of ages 6–8 weeks, 10–14 weeks and > 6 months were used in the experiment. Blood and serum were collected from these rats under fasting conditions. Results: We observed that the majority of hematological and biochemical parameters were significantly influenced by sex and age. Hematological changes were significantly correlated to aging were increased red blood cells, hemoglobin, hematocrit, neutrophils, monocytes and eosinophils in both sexes, as well as decreased platelet, mean corpuscular volume, mean corpuscular hemoglobin and lymphocytes in both sexes. White blood cells of male rats were considerably higher than those of female rats in all age ranges. For biochemistry, increase in glucose, total protein and creatinine were seen in both sexes, along with increases in urea in females and alanine aminotransferase in males. Age was significantly associated with decreased alkaline phosphatase in both sexes. Conclusions: When using Wistar rats as a model, these reference values may be useful in evaluating the results.

Background: Nonhuman primates are used for research purposes such as studying diseases and drug discovery and development programs. Various clinical pathology parameters are used as biomarkers of disease conditions in biomedical research. Detailed reports of these parameters are not available for Indian-origin rhesus macaques. To meet the increasing need for information, we conducted this study on 121 adult Indian rhesus macaques (57 wild-sourced and 64 inhouse animals, aged 3–7 years). A total of 18 hematology and 18 biochemistry parameters were evaluated and reported in this study. Data from these parameters were statistically evaluated for significance amongst inhouse and wild-born animals and for differences amongst sexes. The reference range was calculated according to C28-A3 guidelines for reporting reference intervals of clinical laboratory parameters. Results: Source of the animals and sex appeared to have statistically significant effects on reference values and range. Wild-born animals reported higher WBC, platelets, neutrophils, RBC, hemoglobin, HCT, MCV, and total protein values in comparison to inhouse monkeys. Sex-based differences were observed for parameters such as RBCs, hemoglobin, HCT, creatinine, calcium, phosphorus, albumin, and total protein amongst others. Conclusions: Through this study, we have established a comprehensive data set of reference values and intervals for certain hematological and biochemical parameters which will help researchers in planning, conducting, and interpreting various aspects of biomedical research employing Indian-origin rhesus monkeys.
Experimental Study of Thickness Gradient and Flow Simulation in VARTM Process
Tushar Gajjar,Dhaval B. Shah,S. J. Joshi,K. M. Patel 한국섬유공학회 2020 Fibers and polymers Vol.21 No.2
Vacuum assisted resin transfer moulding (VARTM) process is widely used for manufacturing composite products. It is very difficult to manufacture a composite component with small dimension tolerance using VARTM process. In this research paper, carbon fiber reinforced polymer (CFRP) flat plates have been manufactured using the VARTM process with a different combination of process parameters. The carbon fiber laminates with different thickness have been manufactured using the VARTM process. The thickness of manufactured components has been measured at different locations using noncontact type 3D scanning techniques. The warpage has been determined for each manufactured components. The compaction pressure has been measured using pressure gauge at a different location during manufacturing. The thickness variation, pressure variation and volume fraction have been determined across the length for each manufactured components for different thickness laminates. The mould filling time has been calculated using the numerical approach in ANSYS Fluent software and the same has been compared with experimental results. The percentage difference between the experimental and numerical approach has been found within 5 %.
Cascade of Complications Following Carotid Body Tumor Excision
Pawan K Garg,Sarbesh Tiwari,Tushar S Ghosh,Surendra Patel,Ankur Sharma,Pushpinder S Khera 대한신경중재치료의학회 2021 Neurointervention Vol.16 No.3
Carotid body tumor excision can lead to various complications including vascular injury and pseudoaneurysm formation. Here we describe a case of carotid body tumor excision followed by series of complications including pseudoaneurysm formation, failure of primary surgical repair, carotid stump syndrome following parent artery occlusion, and persistent hypotension.
