Background: Three-dimensional (3-D) modelling can be a useful technical aid and we used it to reconstruct a homicide scene to corroborate the statement of an eyewitness. 3-D modelling of the bloodstain was conducted by Micro Smith Poser 11 and Autodesk 3-Ds Max software. The technique was found to be easily understandable by the police and judiciary in the interpretation of the sequence of the events of the crime. It refuted the eye-witness's account of the actions of the accused who was charged with murder and allowed collection, storage and retrieval of the patho-anatomic information about the deceased.
Conclusion: The checks on the accuracy of statements given by eye-witnesses that can be provided by 3-D modelling may change the outcome of criminal investigations in future.
We report a method to directly 3-D print complex heterogeneous optical phantoms with programmable tissue-mimicking absorption and scattering properties. The proposed approach utilizes commercially available multi-color mixing extruders and off-the-shelf polylactic acid (PLA) filaments, making this technique low-cost and broadly accessible. We systematically characterized optical properties, including both absorption and reduced scattering coefficients, at a wide range of mixing ratios of gray, white and translucent filaments and validated our hypothesis of a linear-mixing model between the filament mixing ratios and the resulting optical properties.
Grape pomace (GP) is a byproduct of the viticulture industry and shows promise for feeding dairy cattle as well as reducing enteric methane (CH) emissions. This study investigates the potential of using fresh GP in dairy cow feeding and its effects on CH emissions. Multiparous Holstein dairy cows (n = 24, 205 ± 39 DIM) were housed in free stall barns and provided rations consisting of alfalfa hay, wheat hay, almond hulls, cottonseed, and grain mix.
Background: This study aimed to compare the efficacy of clear aligners and removable inclined planes (RIP) in management of anterior crossbite in late mixed dentition patients using a 3D digital model.
Materials And Methods: Twenty-four patients with functional anterior crossbite, aged 8 to 12 years old, were randomly assigned to two parallel groups: the clear aligner (CA) group with a mean age of 10.74 ± 1.
Background: This study aimed to investigate the role of membrane vesicles (MVs) from the probiotic Lactobacillus acidophilus in reducing intestinal inflammation and increasing 5-hydroxytryptamine (5-HT) and tyrosine hydroxylase (TH) in the substantia nigra in the 6-hydroxydopamine (6-OHDA) rat model of Parkinson's disease (PD).
Methods: Twenty healthy male Wistar rats were randomly assigned to four groups (n = 5 per group), including a) control, b) 6-OHDA, c) 6-OHDA+MV, and d) sham groups. PD was induced by bilateral injection of 6-OHDA.
Introduction: Regional anesthetic approach and surgical volume have been shown to outcomes in patients undergoing Nuss procedure for pectus excavatum. However, their independent relationship is not described. We investigated how regional anesthesia and surgical volume are associated with length of stay (LOS), postoperative opioid use, operating room utilization, and complications.
