Background: Lumbar vacuum phenomenon (VP) within the intervertebral disc has been classified based on CT imaging. We compared same-patient sagittal CT images and dynamic flexion-extension x-rays to determine if there is a difference in the amount of vertebral instability present between three VP morphologies on CT.
Methods: Anterior subluxation measurements on x-ray were compared with same-segment VP on CT images from the same patient when both findings were present. VP were classified as spot, island, or linear. It was determined if there was a difference in the amount of anterior subluxation between the three morphologies. Secondary analysis looked at whether there was a difference in anterior subluxation between the three groups if patients had undergone a prior lumbar fusion surgery or not.
Results: There was no difference in anterior subluxation between the three groups on dynamic flexionextension x-rays. There was also no difference between the three groups on flexion-extension x-rays when patients were separated based on if they had received or not received a previous lumbar fusion surgery.
Conclusion: IVD VP morphology is not a useful indicator in determining vertebral instability preoperatively according to CT scan. Further fine-tuning of an IVD VP CT classification is needed to help radiologists and spine surgeons know when IVD VP presence is important.

Introduction: The current literature proves that the frequency of anatomical variants of circle of Willis (CoW) has not yet been sufficiently evaluated both in the Romanian population and internationally, and in the North East region of Romania there is no evidence of such research so far. The aim of this study is to identify the frequency and types of anatomical variants of the constituent arteries of the posterior part of the CoW in patients with cerebrovascular diseases diagnosed within the main Neurology hospital in the Northeastern region of Romania, based on macroscopic analysis of arterial specimens obtained at autopsy and to compare the results with data from updated literature.
Material and Methods: Our research represents a descriptive observational study, conducted retrospectively on 96 patients with cerebrovascular diseases who died over a period of 30 months and underwent an anatomo-clinical autopsy. We analysed the general macroscopic aspects of all anatomical variants of the constituent arteries of the posterior part of the CoW, comparing these to the opposite arteries.
Result: Out of the total of 96 available human brains, 28 cases (29.17%) presented anatomical variants of CoW, among which 11 cases (39.28%) presented at least one anatomical variant of the constitutive arteries of its posterior part. The average age of these patients was 59.18 years. 36.36% cases had a single anatomical variant, 54.54% cases had two anatomical variants, and 9.09% all of cases associated an anatomical variant of the posterior part of CoW and one of the vertebral arteries. Anatomical variations of the arteries of the posterior part of the CoW were observed in 14 arteries (31.81%) of all the 44 available, and consisted in unilateral or bilateral hypoplasia (20.45%) or absence (15.90%), located either on the right or on the left, and partial fetal posterior communicating artery (2.27%) located on the left side. We identified seven morphological patterns of the posterior part of CoW in the conditions in which its anterior part does not present any anatomical variants.
Conclusion: The data obtained in the present research allow us to affirm that circle of Willis represents an anatomical structure with a great morphological diversity of its posterior part. This study contributes to the knowledge of this topic in Romania and allows comparisons with data obtained both in the country and abroad.

The increasing morphology of interest in understanding the behaviour of biological neural networks, and the expanding utilization of artificial neural networks in different fields and scales, both require a thorough understanding of how technological computing works. However, von Neumann in his classic ”First Draft” warned that it would be unsound to use his suggested paradigm to model neural operation, furthermore that using ”too fast” processors vitiates his paradigm, which was intended only to describe (the timing relations of) vacuum tubes. Thus, it is worth scrutinizing how the present technology solutions of anatomy can be used to mimic biology. Some electronic components anatomy bears a surprising resemblance to some biological structures. However, combining them using different principles can result in systems with inferior efficacy. The paper discusses how the conventional computing principles, components, and thinking about computing limit mimicking biological systems of morphology and anatomy.

Introduction: Examining and analysing the characteristics features of the vertebral column of human is an important part of the study in anatomy. The vertebral column includes 33 vertebrae that are arranged one upon the other and joined to each other by means of the intervertebral joints and ligaments, of which includes anterior and posterior longitudinal ligaments. Diseases involving the ligaments end in numerous spectrums of ailments extending from backache to deformities and nerve entrapments.
Material and methods: The current study was conducted on 25 dry bone sets. The anterior longitudinal ligaments were studied to find out if there was any change in texture; they were inspected and palpated for any sign of ossification. The study was done randomly at Deccan College of Medical Sciences, Hyderabad
Result: Only 5 of the 25 dry sets of vertebrae examined had indications of ossified ligaments at varying levels.
Conclusion: Inflammation and ossification of the anterior ligament rarely cause symptoms or major functional issues in the patient. In exceedingly rare circumstances, these processes may be linked to the development of a degenerative back problem, however these instances are infrequent.

Labio-maxillo-palatine clefts are malformations of viscerocranium that require a multidisciplinary team for establishing a diagnosis and treatment, involving multiple specialties such as plastic surgery, maxillofacial surgery, ENT, paediatrics, speech therapy, orthodontics. For the accuracy of the diagnosis and treatment these patients require multiple explorations that will involve multiple doses of irradiation. The exploration of these patients starts at an early age and that’s why should have a limited indication. CBCT is a modern exploration that offers a low dose of irradiation. The principle that CBCT uses is similar to the principle of explorations real-time imaging in operating rooms when surgery takes place. Bone defects in the labio-maxillo-palatine clefts require a correct evaluation for the planning of the augmentation intervention of these defects, and the CBCT allows for an optimal 3D assessment to determine their dimensions and the bone required. The use of these explorations facilitates the operating steps. With the development of CBCT, visualization programs and analysis of these explorations were also developed, with necessary tools in linear and volumetric measurement of alveolar bone defect. We performed a retrospective study on patients with labio-maxillo-palatine clefts, diagnosed in the Paediatric Surgery Clinic, Saint Mary's Children's Hospital, Iasi in 2019 to demonstrate the need for an accurate diagnosis using this radiological technique, CBCT and digital planning, and on printed 3D models of surgical interventions to correct alveolar bone defects of the labio-maxillo-palatine clefts.

Embryonic development is a fascinating and intricate process that transforms a single fertilized egg into a complex multicellular organism. Central to this process is neurulation, the remarkable journey during which the nervous system takes shape. Neurulation is a critical stage in embryonic development, laying the foundation for the intricate network that governs all aspects of an organism's functioning. The journey of neurulation begins shortly after fertilization, as the fertilized egg undergoes a series of divisions and differentiations to form a blastula. The blastula, a hollow ball of cells, eventually undergoes gastrulation, a process that transforms it into a gastrula with three germ layers: ectoderm, mesoderm and endoderm. The ectoderm, the outermost layer, plays a pivotal role in neurulation. It is from this layer that the nervous system will emerge. As the gastrula undergoes further transformations, a region of the ectoderm known as the neural plate becomes distinguishable. The neural plate marks the beginning of the intricate process of neurulation.

Background:The basic cone unit in Pinaceaeis called Bract-Scale-Seed Complex (BSSC), in which the scale is supposed to be equivalent to an axillary shoot bearing ovules in Cordaitales. This correlation established by Florin provides a rational foundation on which an interpretation for the origin of cones in at least most Coniferalesis built, and may be called Florin model for convenience. Cupressaceaeis a family in Coniferales, in which the ovule-scale and its subtending bract are thought fully fused and hard to distinguish by external morphology.
Results: Different from Pinaceaeand other typical conifers, Juniperus(Cupressaceae)appears not following Florin’s model closely. For example, the cone of Juniperusoxycedrushas only three rather than more BSSCs in a whorl, and its fleshy fructification appears more like a berry rather than a typical coniferalean cone. In this paper morphology and anatomy of Juniperusoxycedrusfructifications are documented using Micro CT. New observation demonstrates clearly that three seeds alternate the three surrounding bracts in Juniperusoxycedrus.
Conclusion:Such spatial arrangement is quite different from that in typical BSSCs, in which the ovules should be aligned with their subtending bract. Together with other unexpected features in other cupressaceous cones, Juniperusmay help to expand the avenue through which we can interpret the origin and homology of cones in Cupressaceaeand other conifers or gymnosperms in general.

Background: Lumbar vacuum phenomenon (VP) within the intervertebral disc has been classified based on CT imaging. We compared same-patient sagittal CT images and dynamic flexion-extension x-rays to determine if there is a difference in the amount of vertebral instability present between three VP morphologies on CT.
Methods: Anterior subluxation measurements on x-ray were compared with same-segment VP on CT images from the same patient when both findings were present. VP were classified as spot, island, or linear. It was determined if there was a difference in the amount of anterior subluxation between the three morphologies. Secondary analysis looked at whether there was a difference in anterior subluxation between the three groups if patients had undergone a prior lumbar fusion surgery or not.
Results: There was no difference in anterior subluxation between the three groups on dynamic flexionextension x-rays. There was also no difference between the three groups on flexion-extension x-rays when patients were separated based on if they had received or not received a previous lumbar fusion surgery.
Conclusion: IVD VP morphology is not a useful indicator in determining vertebral instability preoperatively according to CT scan. Further fine-tuning of an IVD VP CT classification is needed to help radiologists and spine surgeons know when IVD VP presence is important.
