Gene expression is inherently noisy, posing a challenge to understanding how precise and reproducible patterns of gene expression emerge in mammals. We investigate this phenomenon using gastruloids, an in vitro model for early mammalian development. Our study reveals intrinsic reproducibility in the self-organization of gastruloids, encompassing growth dynamics and gene expression patterns. We observe a remarkable degree of control over gene expression along the main body axis, with pattern boundaries positioned at single-cell precision. Furthermore, as gastruloids grow, both their physical proportions and gene expression patterns scale proportionally with system size. Notably, these properties emerge spontaneously in self-organizing cell aggregates, distinct from many in vivo systems constrained by fixed boundary conditions. Our findings shed light on the intricacies of developmental precision, reproducibility, and size scaling within a mammalian system, suggesting that these phenomena might constitute fundamental features of multicellularity.

Abstract Background previous studies have indicated on association between shift work and lipid profile disturbances. Lipid profile disturbances could be due to internal desynchronization. The aim of this study was to analyze whether there is relationship between shift work and serum lipids, fasting blood glucose and hypertension. Results A total of 424 rail road workers between the ages of 21 and 64 years in this study filled out a questionnaire, and total cholesterol, triglyceride and HDL-C concentration were measured after 12-hours fasting. Association between shift work and biochemical variables and blood pressure were measured. The X2 and fisher's exact test was used for comparing the qualitative variables and for quantitative variables with normal distribution we used the parametric tests. Odds ratio (OR) with the 95% confidence interval (95% CI) was used for comparing the proportions of risk variables. Sub-populations in this study were consisting of 158 (37.3%) shift workers and 266 (62.7%) day workers. High levels of total cholesterol (> 200 mg/dl) and LDL-cholesterol (> 130 mg/dl) were significantly more prevalent in nearly all groups of shift workers irrespective of age. But there is no differences in the serum levels of triglyceride, HDL-C, fasting blood glucose and blood pressure between shift workers and day workers. Adjusted Odd's ratio for the effect of shift working on high serum total cholesterol and LDL-C level were 2.11(95%CI: 1.33–3.36) and 1.76(95%CI: 1.09–2.83), respectively. Conclusion This study showed that high serum total cholesterol and LDL-C level were more common in shift workers than in day workers. This finding persisted after adjustment was made for age and food type. But there was no difference in the prevalence of HDL-C, triglyceride, fasting blood glucose and hypertension between shift working and day working. It was concluded that shift work is a risk factor for lipid profile disturbances.

Situs inversus totalis (SIT) is a rare developmental abnormality where the organs throughout both the thoracic cavity and abdomen are a mirror image of normal anatomy, often occurring concomitantly with other genetic and developmental defects. Acute spinal cord ischemia is diagnosed based on the clinical presentation along with consistent imaging, but since clinical manifestations of acute spinal cord ischemia— rapidly progressive motor, sensory, and autonomic dysfunction—overlap with a wide spectrum of myelopathies, a thorough diagnostic workup with consideration of inflammatory, infectious, compressive and nutritional etiologies is required to establish the diagnosis. In this report, we present the case of an 18-year-old female patient who was admitted with acute onset of severe lower back pain, progressive weakness, paralysis, loss of sensation in both lower limbs and voiding difficulties. The diagnosis of acute spinal cord ischemia in a patient with situs inversus totalis was made. Our case highlights the spectrum of the pathological entities that can be associated with situs inversus totalis. Due to the lack of the classic signs and symptoms of sinus inversus, a diagnosis of situs inversus totalis with concomitant pathological conditions may require a more in-depth evaluation by complex imaging modalities to ensure a comprehensive assessment of the condition and its associated complications.

Parsonage-Turner Syndrome (PTS), also known as brachial neuritis or neuralgic amyotrophy, is a rare disorder affecting 2 to 3 individuals per 100,000 each year. Abrupt onset shoulder pain, followed by motor weakness, paresthesia and hypoesthesia, is usually reported, lasting several months with variable recovery. The etiology of the disease may be idiopathic or triggered by an underlying autoimmune disease in genetically susceptible individuals. Our report addresses a unique case of Parsonage-Turner Syndrome in a patient suffering from concurrent Hashimoto Thyroiditis. A previously healthy A 22 year-old female was referred to the Department of Neurology after complaints of sudden-onset motor weakness in her left upper limb. On physical examination, the patient could not make an “Ok sign” with her thumb and distal phalanx or form a complete fist, revealing weakness within the anterior interosseous branch of the median nerve. Further testing with electromyography demonstrated muscular atrophy within the arm's anterior compartment, forearm, and triceps brachii of the posterior compartment. Additional imaging and physical examination were unremarkable, confirming our diagnosis of PTS. Furthermore, lab reports revealed elevated levels of anti-thyroglobulin and anti-thyroid peroxidase antibodies and our patient was concurrently diagnosed with Hashimoto's thyroiditis.This case aims to highlight the rare co-occurrence of Hashimoto's thyroiditis with Parsonage-Turner Syndrome in an otherwise healthy patient. A 2014 study published by Nugent et al. had also shed light on brachial neuritis in a patient suffering from autoimmune connective tissue disease, and through this case study, we hope to add to the growing literature regarding the correlation between PTS and autoimmune diseases. Symptoms of PTS can easily be misdiagnosed given its similarity to other peripheral neuropathies, and careful assessment and thorough understanding of the disease is required to successfully distinguish it from other neurological pathologies.

BackgroundMagnetic resonance imaging (MRI), cerebrospinal fluid (CSF) analysis, and the McDonald’s clinical criteria are currently utilized tools in diagnosing multiple sclerosis. However, a more conclusive, consistent, and efficient way of diagnosing multiple sclerosis (MS) is yet to be discovered. A potential biomarker, discovered using advances in high-throughput sequencing such as nuclear magnetic resonance (NMR) spectroscopy and other “Omics”-based techniques, may make diagnosis and prognosis more reliable resulting in a more personalized and targeted treatment regime and improved outcomes. The aim of this review was to systematically search the literature for potential biomarkers from any bodily fluid that could consistently and accurately diagnose MS and/or indicate disease progression.MethodsA systematic literature review of EMBASE, PubMed (MEDLINE), The Cochrane Library, and CINAHL databases produced over a thousand potential studies. Inclusion criteria stated studies with potential biomarker outcomes for people with MS were to be included in the review. Studies were limited to those with human participants who had a clinically defined diagnosis of MS and published in English, with no limit placed on date of publication or the type of bodily fluid sampled.ResultsA total of 1,805 studies were recorded from the literature search. A total of 1,760 studies were removed based on their abstract, with a further 18 removed after considering the full text. A total of 30 studies were considered relevant and had their data retrieved and analyzed. Due to the heterogeneity of focus and results from the refined studies, a narrative synthesis was favored.ConclusionSeveral promising candidate biomarkers suitable for clinical application in MS have been studied. It is recommended follow-up studies with larger sample sizes be completed on several potential biomarkers.

"nBackground: Bone turnover is reported to increase in favor of resorption in overt hyperthyroidism and the rate of resorption is associated with the levels of thyroid hormones. As persistent increase in bone turn over is responsible for accelerated bone loss, patients with Graves' disease may have increased risk for osteoporosis. The aim of this study was to determine relationship between Graves' disease and bone markers."nMethods: The subjects of our study were 31 consecutive untreated GD patients and 37 normal volunteers who were matched on sex proportion and age ranging was diagnosed by suppressed levels of TSH and elevated level of free T3 and free T4 and positive thyroid receptor antibody. Through a clinical trial study executed in endocrinology and metabolism research center, we investigated the relationship between serum osteocalcin & cross-laps with Graves' disease and then kinds of treatment with PTU and methimazole after 8 weeks follow up."nResults: No significant differences in age and sex between patients and controls were found. Significant differences in serum bone markers and thyroid hormones were detected between patients and controls before therapy (p< 0.001). After treatment we found a significant improvement and returning to normal range in all serum lab tests. There were not any differences in the effect of treatment on thyroid hormones and bone markers between two groups."nConclusion: We found close relationship between Graves' disease and bone markers. So that treatment of Graves' disease can improve bone turn over. These findings indicated that early diagnosis and management of Graves' disease can be effective for osteoporosis prevention in these patients.
