Heterotopic gastric mucosa (HGM) is an islet of gastric mucosa within the esophageal mucosa. These lesions can sit throughout the digestive tract and rarely in the upper third of the esophagus. The pathophysiology of HGM remains poorly understood. Our study aims to estimate the prevalence of HGM, clinical signs, endoscopic, microscopic aspects and different epidemiological factors associated. All patients from a single endoscopy center with HGM of the upper third of the esophagus were included over a 5-month evaluation period. All lesions seen in endoscopy were confirmed by histological analysis. The prevalence was 1.3% with a clear male predominance. 80% of patients were symptomatic and received medical treatment, clinical evolution was good. No case of dysplasia was identified and no complication was observed. Due to insufficient data in the evolutionary literature, the management of HGM remains debated and could resemble that of Barett’s esophagus for monitoring and therapeutic management, particularly in the event of symptoms or dysplasia.

Hemiscorpius lepturusis a dangerous scorpion and referred to health concern issue in Khuzestan, Iran. The venom of H.lepturus is cytotoxic and its effect is similar to spider Loxosceles reclusa. Metalloproteinases are the important class of enzymes in the venom that has hemorrhagic activity. The early finding suggests the existence of metalloproteases in the transcriptome of venom gland of H.lepturus. Phylogenetic analysis was accomplished to reveal the evolutionary relationship of identified metalloproteases. The phylogenetic tree was constructed by Molecular Evolutionary Genetics Analysis software and neighbor-joining method. Results showed among three sequences, two metalloproteinases named HLMP1 and HLMP3 of H.lepturus were most close to spider P. tepidariorum. The third sequence named HLMP2 was different and formed an independent clade in the phylogenetic tree. The results suggest that the sequence of metalloproteases in the venom component of H.lepturus is similar to the spider than the scorpion.

This review gives a brief introduction to the microarray technology and its experimental design and data analysis and a discussion of recent global progress in research using microarray technology in fish biology and aquaculture. DNA microarrays have been reported to have been used for the analysis of gene expression during various physiological, developmental or cellular processes in fish. During the recent past, investigators have begun to use microarrays on fish to address ecological, evolutionary and environmental questions including the variability of gene expression in natural populations, speciation, ecotype diversity, environmental remediation and host-pathogen interactions. The study suggests that a lot of gene expression studies have been conducted on salmon and zebrafish in Europe and USA. The same may be applied on Indian Major Carps and Catfishes to augment productivity from aquaculture sector. 

Genetic datasets have a large number of features that may significantly affect the disease classification process, especially datasets related to cancer diseases. Evolutionary algorithms (EA) are used to find the fastest and best way to perform these calculations, such as the bat algorithm (BA) by reducing the dimensions of the search area after changing it from continuous to discrete. In this paper, a method of gene selection was proposed two sequent stages: in the first stage, the fuzzy mutual information (FMI) method is used to choose the most important genes selected through a fuzzy model that was built based on the dataset size. In the second stage, the BBA is used to reduce and determine a fixed number of genes affecting the process of classification, which came from the first stage. The proposed algorithm, FMI_BBA, describes efficiency, by obtaining a higher classification accuracy and a few numbers of selected genes compared to other algorithms.

In the classification of cancer data sets, we note that they contain a number of additional features that influence the classification accuracy. There are many evolutionary algorithms that are used to define the feature and reduce dimensional patterns such as the gray wolf algorithm (GWO) after converting it from a continuous space to a discrete space. In this paper, a method of feature selection was proposed through two consecutive stages in the first stage, the fuzzy mutual information (FMI) technique is used to determine the most important feature selection of diseases dataset through a fuzzy model that was built based on the data size. In the second stage, the binary gray wolf optimization (BGWO) algorithm is used to determine a specific number of features affecting the process of classification, which came from the first stage. The proposed algorithm, FMI_BGWO, describes efficiency and effectiveness by obtaining a higher classification accuracy and a small number of selected genes compared to other competitor algorithms.

Introduction - evolution of SARS-CoV-2 variants: With the unrestrained pandemic for over last one-and-half year, SARS-CoV-2 seems to have adapted to its habitat, the human host, through mutations that facilitate its replication and transmission. The G variant incorporating D614G mutation, potently more transmissible than the ancestral virus arose during January 2020 and spread widely. Since then, various SARS-CoV-2 variants of concern (VOCs) and variants of interest (VOIs) with higher infectivity or virulence or both, have evolved on the background of G variant, and spread widely. SARS-CoV-2 infection and the immunodynamics: As the virus becomes more transmissible, its lethality may drop. Apart from the humoral immunity, T-cell recognition from a previous SARS-CoV-2 infection or vaccination may modify the disease transmission correlates and its clinical manifestations. On the other hand, the immunity generated may reduce probability of re-infection as well as limit evolution of adaptive mutations, and emergence of highly infectious and immune-escape variants. There are complex issues related to the SARS-CoV-2 evolutionary dynamics and host’s immunodynamics. Trending etiopathoimmunological correlates: The evolution potential of SARS-CoV-2 is limited because of proofreading function of nsp14. The S protein mutations affect transmissibility, virulence, and vaccine efficacy. The D614G mutation in G variant with higher infectivity has turned the Chinese epidemic into a pandemic. Other SARS-CoV-2 variants, such as Alpha, Beta, Gamma, and Delta seem to have evolved as result of adaptation to selective pressures during periods of prolonged infections and subsequent transmission. Further, there is issue of convergent association of mutations. Basics of immunity and immune system failure: The nature of the immune response after natural SARS-CoV-2 infection is variable and diverse. There are pre-existing neutralizing antibodies and sensitized T cells elicited during previous infection with seasonal CoVs influencing the disease susceptibility and course. The virus has evolved adaptive mechanisms to reduce its exposure to IFN-I and there are issues related to erratic and overactive immune response. The altered neutralizing epitopes in the S protein in SARS-CoV-2 variants modify the immune landscapes and clinical manifestations. Conclusion: current scenarios and prospects: Presently, the SARS-CoV-2 infection is widespread with multiple evolving infectious variants. There is probability of its transition from epidemic to endemic phase in due course manifesting as a mild disease especially in the younger population. Conversely, the pandemic may continue with enhanced disease severity due to evolving variants, expanded infection pool, and changing immunity landscape. There is need to plan for the transition and continued circulation of the virus during the endemic phase or continuing pandemic for indefinite period.

Depression is currently one of the main barriers to further civilizational development. Despite intensive efforts, it is a growing health, social and economic problem. We still lack clarity regarding the ethology of depression and treatment is still mainly symptomatic. The authors postulate that depression has similarities with anxiety and from an evolutionary perspective is an archaic defence mechanism. Formerly, through the agency of complex psychological, biological and social mechanisms, healing was facilitated in conditions of an intense, short-term nature. Adverse civilizational and environmental changes have caused pathological changes in both the mechanism of depression and corresponding defence mechanisms such as the induction of an anxiety state. Related to depression is the mechanism of thanatosis, concerning chronic biological and psychosocial dysfunctions. It is a mechanism for activating self-eliminating processes to free the community from the burden of a dysfunctional individual.

In order to better understand some neurologic degenerative process is fundamental to use also an evolutionary approach of vertebrates and especially in mammalians. Aim of this work is to verify if an objective measure of brain wasting system can help in this kind of disease. Imaging can help in measuring efficiency of brains wasting system in the various subject. The brain glymphatic systems is well studied today but an accurate measure of the real efficiency of the system is needed. It is relevant so to submit to researcher a working methods strategy to measure this parameter to verify if possible, to use the brain glymphatic system as new therapeutics pathway.

Synthetic biology is an interdisciplinary branch of biology and engineering. The subject combines various disciplines from within these domains, such as biotechnology, evolutionary biology, molecular biology, systems biology, biophysics, computer engineering, and genetic engineering. Synthetic biology aims to understand whole biological systems working as a unit, rather than investigating their individual components and design new genome. Significant advances have been made using systems biology and synthetic biology approaches, especially in the field of bacterial and eukaryotic cells. Similarly, progress is being made with ‘synthetic approaches’ in genetics and animal sciences, providing exciting opportunities to modulate, genome design and finally synthesis animal for favorite traits.

In the evolutionary journey of humanity, it is possible to verify an analysis of pandemics with high occurrences. This study aims to conduct a critical analysis of the role of Vitamin D as an endogenous vaccine in the main viruses present in humanity over the decades. To construct this text, we used the short review methodology through a critical analysis. This study demonstrated the importance of using Vitamin D as an endogenous vaccine when used frequently in both healthcare professionals and patients. Therefore, it is concluded that Vitamin acts protectively in the innate immune system.

Introduction: In Madagascar, plague is a highly contagious acute endemic infectious disease. The diagnosis of the most severe form of pneumonic plague remains difficult in children, hence the objectives of the present study; which is to identify the clinical signs of this clinical form in children and to describe its epidemiological and evolutionary profile. Methods: A retrospective case-control study was conducted in four pediatric wards in Antananarivo during the urban pneumonic plague outbreak from September 2017 to January 2018. Those cases were defined as children aged 0-15 years old suspected of having plague with positive RDT and PCR, and they were defined as children aged 0-15 years old with negative RDT and PCR. Results: Fifty-two cases of pneumonic plague were identified, half of which (50%) were under 24 months of age. A male predominance was noted with a sex ratio of 1.23 and 86.54% of the patients were from urban areas. Several clinical signs were found but none was specific for pneumonic plague: cough (59.62% p: 0.5), dyspnea (3.85% p: 0.16), chest pain (3.85% p: 0.26%), hemoptysis (7.69% p: 0.17), vomiting (9.62% p: 0.14), diarrhea (11.54% p: 0.45), altered general condition (38.46% p: 0.24%). Two deaths were noted (3.8%). Conclusion: No specific clinical warning signs have been identified in childhood pneumonic plague. In the event of an epidemic of urban pneumonic plague, any bacterial pneumonia should at least initially include active treatment against Yersinia pestis.

Introduction: Neurocysticercosis (NCC) is a common helminthic infection of the nervous system that occurs when humans become intermediate hosts in the life cycle of the pig tapeworm (Taenia solium) after ingesting its eggs. The objective of this study was to analyze socio-demographic, clinical and paraclinical features of patients with NCC in Lubumbashi, DRC. Methods: This is a cross-sectional study conducted over a period of 2 years within the Neuropsychiatric Center of Lubumbashi. Socio-demographic, clinical, paraclinical and therapeutic features were studied. Results: A total of 18 patients with NCC were listed. Epilepsy was found in 72.2% (13/18) of the cases. The mean age of the patients was 30.2 ± 13.5 years; males accounted for 61.2% of the cases. 84.6% were consumers of pork. Generalized epilepsy was found in 84.6% of the cases and hypereosinophilia in 38% of the cases. On the neuroimaging, the parietal location of lesions represented 92.3%; calcifications were the type of lesion in 53.8% of the cases and 69.2% of the cases presented lesions in the 4th evolutionary stage. Electroencephalogram was normal in 84.4% of the cases. Phenobarbital was the antiepileptic drug used in 69.3%; albendazole and prednisone were used in 53.9% of the cases. Conclusion: This study shows that NCC is one of the causes of epilepsy in Lubumbashi. Generalized tonic-clonic seizures are the most common form of presentation and calcified parenchymal lesions are the most common radiological feature of NCC. So, any patient with acute onset of afebrile seizure should be screened for NCC provided other common causes been ruled out.

Targeted screening for Cytomegalovirus (CMV) in Deaf and Hard of Hearing (DHH) children is now internationally recommended. With newborn genomic screening for DHH children a future possibility, the commercially-available human genomic DNA collection kit (ORACollect, Oragene OCR-100) could enable one single sample to screen for CMV and genetic causes of deafness at scale with minimal additional costs. Our pilot study validated ORACollect against Copan FLOQswabs® (gold standard clinical procedure) for detecting CMV using 15 sets of saliva samples from 14 infants/children, comparing CMV PCR results using different testing protocols. ORACollect stored at room temperature had high sensitivity (up to 89%), specificity (up to 80%) and percent agreement (up to 86%) in detecting CMV DNA compared to FLOQswabs®. This suggests that ORACollect is an appropriate alternative to FLOQswabs® for collecting viral CMV DNA for PCR testing, independent of the DNA extraction approach. This could be revolutionary in facilitating dual genomic and viral screening in newborns and would enable CMV screening in non-tertiary hospital settings where laboratory facilities are not available.

Known since antiquity, migraine is a complex primary disorder, an episodic painful Autonomic Nervous System (ANS) storm, generally following the stress/post-stress phase. Despite exhaustive study of neuropeptides, neurochemicals, molecules, neurogenetics, neuroimaging along with animal and human experiments over the last 50 years, the scientific basis of migraine remains unknown. Straddling eight decades from Cortical Spreading Depression (CSD) to Calcitonin-Gene Related Peptide (CGRP) and its antagonists, exponentially increasing data have failed to create a gestalt synthesis. This article lays cohesive and robust fundamental principles for the comprehension and management of migraine. The continuum between migraine and non-congestive Primary Open-Angle Glaucoma (POAG), Normal Tension Glaucoma (NTG), or Low-Tension Glaucoma (LTG) is advancing. The case of sustained remission of migraine attacks (> 75%) over 3 years - 5 years with ocular hypotensive topical Bimatoprost Ophthalmic Solution (BOS) 0.3% in an N-of-1 trial in 3 patients with refractory migraine is presented. A cause-effect-adaptive process underlies the ANS-stress/post-stress-linked biology of migraine. Vasopressin-serotonin-norepinephrine ‘homeostatic-adaptive system’ Lowers Intraocular Pressure (IOP), while enhancing anti-stress, antinociception, vasomotor, and behaviour control functions, thereby selectively decreasing algogenic neural traffic in the ophthalmic division of trigeminal nerve (V1), and, raising the threshold to develop migraine. Striking migraine headache-aborting feature of vomiting is also likely linked to a several hundred-fold increase in arginine-vasopressin secretion. Eye-cover tests and self-ocular digital displacement are essential to studying the visual aura. Real-time physical displacement of Scintillating Scotoma (SS) and floating ‘stars’ is reported. The basis of spontaneous onset and offset, self-limited duration of migraine attacks, as well as female preponderance, and age/menopause decline in prevalence, are elucidated. Intraocular implants with long-term ocular hypotensive effects, including bimatoprost, are the future of migraine management. Controlled trials are required to establish the migraine-preventive effect of topical bimatoprost, a revolutionary advance in neuroscience.

The radioactive isomer was initially used to characterize persistent excited atomic states, much like molecular isomers, more than a century ago. Otto Hahn made the first atomic isomer discovery in 1921.  Subsequently, it was gradually discovered that there are several kinds of nuclear isomers, such as spin isomer, K isomer, seniority isomer, and “shape and fission” isomer.  Isomers are essential to the nucleosynthesis of astrophysical materials. High-accuracy nuclear reaction rate inputs are anticipated while carrying out a celestial nucleosynthesis net computation, even though a single reaction rate can have a significant impact on the whole astronomical evolutionary network. The isotopes are often considered to be in their initial state or to have levels populated in accordance with the thermal-equilibrium distribution of chances when computing nuclear synthesis rates. After all, certain isomers may have lives that reach millions of years or perhaps beyond the age of the cosmos. Thus, in an astrophysics event, such isomers might not be thermally equilibrium. Some atomic isomers—that is, astrometry—should be considered special isotopes since they are crucial to nucleosynthesis. Nuclear batteries can also be produced using nuclear isomers. Similar to the weak force, in certain specific cases such as isomer decays, the electromagnetic force could be crucial for nuclear changes. It is important to note that radioactive isomer states and radioactive ground states are not the same thing.  Durable nuclear states of excitement provide insight into the nuclear framework and potential uses. Atomic and molecular changes become interconnected when the connection to the electrons in atoms is made possible by the existence of em decay routes from isomers. Notably renowned chemical decay process is inner conversion. Its inverted, nuclear excitement by free capture of electrons has been observed; however, it is debatable and needs more investigation. This study describes the connection connecting radioactive and molecular changes and discusses instances of manipulating nuclear moves related to isomers using external electromagnetic fields.

The incidence of obstetric acute renal failure remains significant in developing countries. The aim of our study is to define the risk factors involved in the occurrence of ARF during pregnancy or during the immediate postpartum period and to evaluate its evolutionary profile in terms of epidemiology, etiopathogenesis, and therapeutic management over the years in Morocco. This is a retrospective study conducted in the maternal-infant resuscitation service of the Ibn Rochd University Hospital of Casablanca, over the period from January 2020 to August 2023, including 95 patients. The current incidence in our series over this period was 22.2%. The mean age of our population was 33 ± 7.74 years [18-43 years], 67.3% of patients were in the gestational period, compared to 33.7% in the immediate postpartum period. Fourteen patients were primiparous (8.6%), 27.4% had a history of miscarriage, and 10.7% had a history of pre-eclampsia. Oligo-anuria was initially identified in 24 patients. The most frequent etiology was pre-eclampsia (56.7%), followed by hemorrhage (27%) and sepsis (19.3%). The evolution was marked by recourse to hemodialysis in 62% of cases, with a maternal mortality of 26%. The existence of heart disease, the context of pre-eclampsia, and the use of diuretics and vasoactive drugs were significantly correlated with maternal survival. No factor was correlated with secondary recovery from ARF. The development of health structures and the optimization of screening strategies are the keywords for prevention.

While efforts have been made to ensure accuracy and maintain the original meaning, some nuances or interpretations may differ from the source text. For any clarification, please refer to the original document or contact the author.This brief article addresses the concern arising from the accelerated whirlwind of changes of all kinds experienced by our social systems, some of which have a significant evolutionary impact, largely driven by advances in science and technology. Particular interest has emerged in connecting certain properties inherent to the behavior of complex systems far from equilibrium—such as social systems—under the framework of properties currently studied in Complexity Sciences. The article outlines this concern, which is, for now, merely the beginning of what could develop into a groundbreaking investigation. It references laboratory simulation work aimed at understanding the evolutionary horizons of Chile’s social system. The text includes an example of some graphs that illustrate a potential method for detecting and anticipating possible evolutionary horizons of the social system, based on the role played by certain “attractor variables” within the system. However, the research is still exploratory, and this article serves merely as a general description of the initial concern.
