Boron neutron capture therapy for the treatment of lung cancer and assessment of dose received by organs at risk

Published on: 16th September, 2022

Recent studies on boron neutron capture therapy (BNCT) have focused on investigating the appropriate neutron sources based on accelerators for neutron production, such as 7Li(p,n)7 Be. The therapeutic abilities of BNCT have been studied for the possible treatment of lung cancer using thermal and epithermal neutron beams. For neutron transport, the Monte Carlo N-particle transport code was used, and doses in the organs of different Oak Ridge National Laboratory phantoms were evaluated. The right lung was meshed with voxels to obtain depth-dose distributions using 1 eV, 10 eV, 100 eV, 1 keV, 5 keV, 8 keV and 10 keV energy sources. These results suggest that BNCT with an epithermal neutron beam can be used to treat lung cancer. By evaluating the biological dose rate and dose-depth distribution curves in healthy tissues and tumors by simulating a lung phantom, the quantities in the phantom were also evaluated. Our calculations show that with increasing boron concentration applied to the tumor, the dose is increased and the 100 eV energy source has the greatest effect on the tumor dose.

A case of coexistent acute severe alcoholic and Q fever hepatitis: The useful contribution of repeated liver biopsies

Published on: 23rd September, 2022

Acute Q fever is a worldwide zoonotic infection due to C. burnetii that may be associated with hepatitis. Nonspecific clinical and biological manifestations may accompany liver involvement, including hepatomegaly and elevated liver biological tests. However, the presence of jaundice is rare. Therefore, making a diagnosis of Q fever hepatitis may be difficult in an afebrile patient with jaundice of recent onset, altered liver function tests, excessive alcohol intake and no reported contact with animals. We report here the diagnostic work-up and complex clinical management of a patient presenting with acute hepatitis resulting from both C. burnetii infection and severe alcoholic steatohepatitis. Positive serology together with a detailed examination of the liver biopsy was able to reveal the coexistence of both Q fever hepatitis with typical fibrin-ring granulomas as well as florid lesions of alcoholic steatohepatitis. A combination of antibiotics, hydroxychloroquine and steroids, guided by the helpful description of changes in histological alterations on repeated liver biopsies during the course of the disease contributed to the slow but favorable outcome.

Enhancing functional expression of L-glycerophosphate oxidase in Escherichia coli by controlling the expression rate

Published on: 4th July, 2022

OCLC Number/Unique Identifier: 9632289800

Heterologous expression of proteins often pursues high expression levels, but it can easily result in misfolding and loss of biological function. L-α-glycerophosphate oxidase (GlpO) is a flavin adenine dinucleotide (FAD)-dependent oxidase which is widely used in the clinical determination of triglycerides. We found that the total enzymatic activity of GlpO expressed in Escherichia coli (E. coli) was extremely low, probably due to the absence of FAD cofactors and the misfolding of GlpO at a high synthesis rate. Therefore, decreasing the expression rate was used to improve the activity of GlpO. The specific activity of GlpO expressed on the pUC19 vector with lac promotor was approximately 30 times higher than that expressed on the pET28a vector with T7 promotor, but the expression levels of GlpO on the two vectors were completely opposite. It indicated that the specific activity of GlpO was increased as the expression level decreased. However, too low expression greatly influences the total amount and activity of the functional enzyme. In order to resolve this problem, two new plasmids, GlpO-CG4 and GlpO-CG6, were constructed by inserting 4 or 6 nucleotides, respectively, between the ribosome binding site (RBS) and the start code (ATG) on pET28a. Compared with the expression on the GlpO-pET vector, the expression rates of GlpO on the GlpO-CG4 and GlpO-CG6 were dramatically decreased. The total activity of GlpO expressed on GlpO-CG6 was 11 times and 1.5 times higher than that expressed on the GlpO-pET and GlpO-pUC, respectively. Results suggest that the activity of GlpO can be improved by decreasing the expression rate.

Bioinformatics as a modern tool in forensic science for data understanding & investigation in research

Published on: 8th December, 2022

Modern-day biology is witnessing a data explosion with a vast amount of information generated from ongoing genome and sequencing projects. The abundance of data from genome sequences, functional genomics and another high throughput (HTP) technique with the potential of computing has led to rising of a new discipline namely ‘bioinformatics’. Bioinformatics is a young but fast-growing field for biological data collection, organization, interpretation, and modeling. Tools and techniques for bioinformatics are derived from multidisciplinary combinations of varied disciplines from natural and physical sciences. Previously various disciplines were carved out as and when sufficient specialization was achieved. However, now bioinformatics is borne out of an alliance between existing disciplines from life and non-life. Bioinformatics encompasses new foundations for the collection, organization, and mining of gene/ protein sequences, three-dimensional structures, and biochemical functions, for modeling biological processes of functioning cells. DNA sequencing performed on an industrial scale has produced a vast amount of data to analyze. Although the Human Genome Project is officially over, improvements in DNA sequencing continue to be made. The field of forensic science is increasingly based on biomolecular data and many European countries are establishing forensic databases to store DNA profiles of crime scenes of known offenders and apply DNA testing.

Meigs syndrome: About an uncommon case report

Published on: 6th January, 2023

Background: Ovarian fibroma is a very unusual epithelial tumor representing less than 1% of all ovarian tumors. It can be asymptomatic and discovered during surgery or be associated with a pleural effusion preferentially located on the right side and a more or less abundant free ascites in the framework of the so-called Meigs syndrome. The challenge of management then lies in distinguishing benign from malignant since clinically, radiologically, and biologically everything points towards malignant which requires radical surgical treatment. We report here the case of a 69-year-old postmenopausal patient with a clinical form of Meigs' syndrome that strongly suggested ovarian cancer.Case presentation: We hereby report here the case of a 69-year-old patient, menopausal, gravida 4 para 3 with 3 live children delivered vaginally and one miscarriage. She presented with ascites, hydrothorax, and a solid tumor of the ovary. Serum CA 125 and HE 4 levels were very high. ROMA score was highly suggestive of malignancy. A hysterectomy with adnexectomy was performed. It was only the histological evidence of ovarian fibroma and the rapid resolution of its effusions that confirmed Meigs syndrome.Conclusion: Meigs syndrome is an anatomical-clinical entity that associates a benign tumor of the ovary, ascites, and hydrothorax. Highly elevated CA 125 and HE-4 tumor markers often point clinicians toward a malignant tumor and compel radical surgical treatment. This case report reminds us once again that only histology confirms the diagnosis of cancer.

Feasibility study of magnetic sensing for detecting single-neuron action potentials

Published on: 31st December, 2022

Understanding the magnitude of the local magnetic fields generated by neurons is critical to assessing the feasibility of novel magnetic field sensors to record in vivo neuronal activities at cellular resolution. However, the strength of the magnetic fields induced by individual neurons and neuronal networks has not been systematically studied. This step is critical for evaluating and benchmarking the ability of different magnetic field sensors to record neuronal activities with far better spatial and temporal resolution. Herein, FEM exemplary models and open-source computational libraries are used to calculate the magnetic fields generated by individual neurons and neuronal networks at micrometer distances. Our theoretical results show that the magnetic field generated by a single-neuron action potential can be detected by ultra-high sensitivity sub-pT magnetic field sensors, which opens the door to future in vivo decoding of neuronal activities through custom neural networks. We anticipate that the identification of single-neuron signals with high-sensitivity magnetic devices will allow the interface of nanoscale devices to interpret biological signals supported by machine-learning techniques capable of monitoring and predicting the localized activities underlying brain computations.

Studies on some spices and herbs: Chemical composition, health benefits and functional properties

Published on: 6th February, 2023

A comprehensive study was carried out to assess the microbiological, nutritional, biochemical and essential oil characteristics of three Egyptian traditional cultivars seeds, namely, cumin (Cuminum cyminum) and coriander (Coriandum sativum) spices as well as basil whole herb (Ocimum basilicum) collected from different Egyptian export centers as being ready for export. The found values for humidity in dry seeds of cumin (7.4%) and coriander (6.4%), as well as total ash and ash insoluble in acid (in cumin 7.7% and 0.74%, but in coriander 5.3% and 0.55%, respectively), were lower than the maximum limits indicated by the Egyptian Specification Standards (ES) and by International Standards Organization (ISO) for cumin and coriander seeds. Analysis of essential minerals in seed spices and herbs indicated that they were rich in K, Ca, Na, Fe and Zn. The total bacterial count was low content in seeds of cumin and coriander as well as fresh whole basil herb. The microbiological load in all tested seed spices and herbs was found lower than those indicated by the ES and ISO for cumin and coriander seeds. Yields in hydro-distilled essential oils (EOs) were the highest in cumin seeds (3.762%), while both coriander and basil herbs had lower amounts (0.285% and 0.686%, respectively). EOs contents were found higher than the maximum limits for cumin (1.5% - 2.5% on a dry weight basis), but within the limits for coriander (0.1% - 0.5% on a dry weight basis) as indicated by the ES and ISO for cumin and coriander seed oils. Gas chromatography of extracted EOs from seeds of cumin and coriander as well as basil herbs indicated the presence of 41, 35 and 47 compounds, respectively, where cumin aldehyde was the major component in cumin volatiles but was linalool in volatiles of both coriander seeds and basil herbs. EOs of basil herbs grown in Egypt were of the high linalool chemotype which was characterized by high contents of linalool and relatively lower amounts of eugenol. However, the major compounds in the three tested EOs from seeds or herbs grown in Egypt are in accordance with literature reports from different parts of the world. Volatile oil components in EOs of the three tested Egyptian spices and herbs were classified into groups, based on the relative area (%). The proportion of the major and the other main components in EOs from seeds of cumin and coriander cultivars were within the ranges indicated by both the ES and ISO for cumin seed oils (cumin aldehyde between 15% - 46%) and for coriander seed oils (linalool between 65% - 78%). The aim of the present work was to Assessment study certain commonly used Egyptian spices and herbal products for characterizing their physical, biochemical and microbiological properties.

The effects of hemp seed consumption on depression, anxiety and cognitive improvement based on machine learning

Published on: 11th March, 2023

Background: Hemp seed (Cannabis sativa L.) is an annual herbaceous plant of the Cannabis genus that contains a large amount of protein, iron, and fatty acids, including linoleic, α-linolenic, and γ-linolenic acid. These compounds are involved in a number of biological activities, including immunity enhancement, hyperlipidemia, and inflammation reduction. Here, we investigated the antioxidant effects of hemp seed on human cognitive function.Methods: The test was administered to 34 healthy volunteers aged ≥ 20 years. Participants were selected according to age and sex and were administered 10 g of hemp seed three times daily (30 g/day) for 45 days. The outcome measurements were recorded using a survey, computerized neurocognitive tests, and artificial intelligence.Results: Survey analysis determined that both the Beck Anxiety Inventory and Beck Depression Inventory measurements decreased significantly after hemp seed consumption when compared to measurements taken before consumption (p < 0.05). Additionally, significant results were observed in the Stroop and Tower of London tasks (p < 0.05). The prediction performance for the antidepressant effect was 0.83 for the area under the curve in the random forest algorithm, which was superior to that of other machine learning methods. Conclusion: These results suggest that hemp seeds have a beneficial effect on cognitive impairment.

Comparative characterization between autologous serum and platelet lysate under different temperatures and storage times

Published on: 12th April, 2023

Therapies using autologous serum and platelet lysate have shown promise among blood and biological products in the treatment of various diseases. The autologous serum has been shown to be a superior alternative to traditional eye drops in treating eye diseases in ophthalmology. Platelet lysate (PL) has recently been considered a more interesting alternative for the treatment of multiple tissues, as it does not have the unfavorable reactions seen with traditional platelet-rich plasma (PRP), making it a valuable blood derivative for use in ocular therapy. There is no definitive comparison in veterinary medicine between PL and autologous serum in terms of the content of Transforming Growth Factor beta 1 (TGF-1), which is known to have chemotactic, mitogenic, matrix formation, and angiogenesis effects on tissues, and beneficial proteins in ocular tissue. This study aimed to estimate the concentrations of TGF-1, total protein, and albumin, as well as autologous serum and platelet lysate, in horses over an 8-day storage period at temperatures of 4 °C and 37 °C.To produce autologous serum, 63 ml of blood was collected from each animal in seven 9 ml tubes without anticoagulant. For platelet lysate, 180 ml of blood was collected in 50 tubes of 3.6 ml with 3.2% sodium citrate. The most significant findings were the positive relationship between the baseline platelet count in the blood and the final platelet concentration in PRP. Specifically, we found a correlation (R = 0.9) with a p - value of 0.005 between the average baseline platelet level of seven animals and their corresponding PRP results, both on an individual level and as a group. Additionally, there was a correlation between growth factor concentration and PRP platelets, with the highest growth factor concentration in PL. The temperature storage group exhibited higher concentrations of total protein and serum albumin, as well as the maximum amount of growth factor for both products at a temperature of 37 °C.

Nuclear science and magnetic carbon: a promising way from a chemical method to detect and fight cancer and tumors/neoplasms

Published on: 17th April, 2023

In 2005 we reported for the first time on a chemical route aiming to synthesize stable magnetic carbon/graphite. By using the Nuclear Magnetic Resonance (NMR) technique we have verified that its magnetism is an intrinsic property of this synthesized material and not originated from ferromagnetic impurities of any kind. Through direct measurement of the local magnetic field using Carbon-13, we have concluded that its magnetism originated from defects in the structure. From its biocompatibility, we have been working on the use of magnetic carbon/graphite to deliver many compounds aiming to fight different diseases. Despite all the scientific and technological advances of the present day, cancer is a multifactorial and difficult-to-treat disease, killing hundreds of thousands of people a year worldwide. Therefore, the development of a new and efficient drug delivery system to fight cancer – among other diseases - is as important as the discovery of a novel active molecule. In this review of our own work, we show the drug delivery system named MAGUS® (an acronym for Magnetic Graphite Universal System) we have built based on nanostructured magnetic carbon/graphite. This is an innovative and promising system composed of a biocompatible nanostructured particle of magnetic carbon/graphite functionalized with different molecules and materials. MAGUS®, depending on what we link to its structure, is so versatile and can be used to detect a wide range of specimens, from tumors and cancers to chemical and biological agents used as non-conventional weapons. That is why we call it universal. In the present work, MAGUS® will be acting as a biosensor, where the magnetic carbon/graphite is functionalized with radioactive particles of Iodine-131 and antibodies of different types of cancer. Then, by focusing on both the antigen-antibody interaction and the spatial guiding through an external magnetic field we are providing our drug delivery system a double way to detect and reach just the target. Based on these strategies, the functionalized magnetic carbon/graphite will reach only the neoplasm and not the surrounding healthy cells around. In a general view, it means that we are giving specificity to the MAGUS® drug delivery system as a pioneering and effective way to detect and treat cancers. We are also working on this unprecedented and efficient drug delivery system using the principles of Boron Neutron Capture Therapy (BNCT) with Boron-10 instead of Iodine-131. BNCT technique uses neutrons as the external source and is frequently employed to treat specific tumors that are radio resistant or very difficult to kill using conventional radiation therapy. In summary, we show here for the first time that our Magnetic Graphite Universal System associated with nuclear techniques can be successfully used as a biosensor to detect and fight cancers and tumors with powerful features that conventional delivery drug systems and other treatments do not have at all.

Identification and Infrared Spectroscopic Study of Lapachol, β-Lapachone and Hydroxy-hydrolapachol

Published on: 6th July, 2023

Metabolites of Brazilian Cerrado species are considered an immense font of biologically active compounds The diversity of organic compounds generated by the secondary metabolism of various Cerrado plants draws attention especially because many of these compounds have the capacity to be structurally modified and, consequently, produce other very interesting derivatives for pharmacological purposes. Despite this, little is described in the literature about fast, easy, and accessible identification methods for any laboratory, such as infrared spectroscopy. In this sense, this work demonstrates the synthesis and elucidation through spectroscopic techniques of lapachol and its synthetic derivatives. Through quick and simple extractions or reactions, lapachol, β-lapachone, and hydroxy-hydrolapachol were obtained with adequate yields. From this, the main FTIR absorptions of the mentioned naphthoquinones are described, which facilitates the identification of these metabolites with high biological potential. The present work contributes could become a simpler source of data for extraction, synthesis, and spectroscopic characterization by FTIR of the compounds.

Review of the Efficiency of Ten Different Commercial Kits for Extracting DNA from Soil Mixed Biological Samples

Published on: 19th July, 2023

Soil-mixed bodily fluids are the most common kind of evidence at outdoor crime scenes. This biological evidence contains DNA, which is a key component of forensic science’s ability to prove an accused person’s guilt because it connects the victim and suspect to the crime scene and aids in identifying the offender and victim. The yield of DNA is significantly influenced by factors including temperature, humidity, storage environment, time since deposition, etc. DNA degradation is caused by a variety of microbes, bacteria, humic acid, and other substances present in soil. Nowadays for DNA extraction, a variety of commercial DNA extraction kits was used now. This paper’s objective is to compare the efficiency of ten different commercial kits used to extract mixed DNA samples. It has been observed that samples stored at a low temperature (-20 °C) are the best for soil blood mixture samples. Compared to samples paired with other types of soil (silt, clay, and marshland), sand soil had the largest production of DNA using the QIAmp investigator kit (Qiagen). Blood Miniprep kit extractions were mostly inhibited, the control that amplified confirms that this kit was the worst in terms of DNA extraction potency. The samples with fewer dirt particles had a much greater yield of DNA.

Microbial Conversion and Utilization of CO2

Published on: 4th September, 2023

Rising greenhouse gas emissions have contributed to unprecedented levels of climate change, while microbial conversion and utilization of CO2 is a practical way to reduce emissions and promote green manufacturing. This article mainly summarizes several natural CO2 pathways that have been discovered, including the Calvin cycle, the reduced tricarboxylic acid (rTCA) cycle, the Wood–Ljungdahl (WL) pathway, the 3-hydroxypropionate/4-hydroxybutyrate (HP/HB) cycle, the dicarboxylate/4-hydroxybutyrate (DC/HB) cycle, the 3-hydroxypropionate (3HP) cycle, the reductive glycine (rGly) pathway, and artificially designed carbon fixation pathways includes the CETCH cycle, the MOG pathway, the acetyl-CoA bicycle, and the POAP cycle. We also discussed applications of different carbon fixation enzymes, notably ribulose-1, 5-diphosphate carboxylase/oxygenase, pyruvate carboxylase, carbonic anhydrase, as well as formate dehydrogenase. This paper further addressed the development of photosynthetic autotrophs, chemergic autotrophs and model bacteria Escherichia coli or yeast produced main products for CO2 fixation through metabolic engineering, such as alcohols, organic acids, fatty acids and lipids, bioplastics, terpenoids, hydrocarbons, and biomass.  Future studies on CO2 microbial conversion should focus on improving the efficiency of carbon fixation enzymes, metabolic modules of the carbon sequestration pathway, and intracellular energy utilization. Coupled microbial and electrochemical methods for CO2 fixation, in addition to biological fixation, show considerable promise.

Pattern of Clinical Presentation and Management of Inflammatory Bowel Disease

Published on: 12th September, 2023

Background: Inflammatory bowel disease (IBD) is characterized by non-specific chronic relapsing inflammation of the gastrointestinal tract and extra-intestinal manifestations. It includes Crohn’s disease (CD) ulcerative colitis (UC) and unclassified colitis.Objective: To assess the clinical presentations and management of inflammatory bowel disease in Sudanese patients.Methodology: Prospective, cross-section hospital-based study was conducted at Soba University Hospital (SUH) and Ibn Sina Hospital, in a period from December 2016 to March 2017. Data was entered and analyzed with SPSS, an interview questionnaire containing demographic, clinical, type of IBD, treatment, and complications.Results: A total of 64 IBD patients were included, 50% were diagnosed with UC, 28.1% with CD and 21.9% unclassified type. The most frequent age in UC patients was 41 – 50 years 34.4%, in CD was 31- 40 years 38.9% and for the unclassified type was 51 – 70 years 57.2%. The female was higher in CD while males were higher in Ulcerative colitis disease, symptoms were diarrhea, rectal bleeding, abdominal pain, rectal pain, tenesmus and fatigue. Study participants received 5 amino salicylic acid, and steroids, especially in the oral formulation. Minimal usage of topical forms, azathioprine, and biological agents. Conclusion: The study concluded UC is more common than CD. This should be taken into account as an important update for internal medicine professionals to adjust their expectations and lines of diagnosis, and management. The emergence of the unclassified type in Sudan requires good communication between the pathologists and the physicians and MDT meetings in every patient with suspicion of IBD.

Massive Adult Adenoviral Adenoiditis Mimicking Lymphoma

Published on: 2nd October, 2023

Hypertrophy of the adenoid is a rare condition in adults, often suspicious of malignancy. We present a case of a 31-year-old female with a clinical presentation of a giant nasopharyngeal mass, clinically suspicious for malignancy, given the size and greyish discoloration. She presented with left-side otalgia, hearing loss, and nasal obstruction. After broad investigations on adenoid tissue following adenectomy, a reassuring diagnosis of adenovirus-related adenoiditis could be made. This case demonstrates the importance of broad microbiological testing in ruling out malignancies. The patient recovered completely.

Production of L-Asparaginase by Yemeni Filamentous Fungi

Published on: 23rd October, 2023

Yemen with its diverse climatic regions represents a rich resource for bioactive compounds obtained from microorganisms. This study was designed to screen fungal isolates obtained from the Microbiology branch, Biological Sciences Department, Faculty of Science, Sana’a University for their ability to produce L-asparaginase enzyme. In preliminary screening for L-asparaginase, among 77 fungal isolates about 29 fungal isolates representing 37.66% were high producers of L-asparaginase. These fungal isolates belonged to the genera Aspergillus, Eupenicillium, Fusarium, Penicillium, and Stachyobotrys. These 29 fungal isolates were screened for their ability to produce L-asparaginase using the agar well diffusion method. 12 fungal isolates out of 29 showed the ability to produce extracellular L-asparaginase. These isolates belonged to 8 species which were: A. sulphurs, A. ustus, F. sacchari, P. chrysogenum, P. citrinum, P. corylophilum, P. melinii, and P. subturcoseum. Only 5 isolates were obtained for the determination of enzymatic activity, among them P. chrysogenum showed the highest activity (279.8696U ml-1) followed by A. ustus (170.9435U ml-1).

An Executive Information System: Inherent Information and Functional Information

Published on: 31st October, 2023

This review article deals with quantum biology, the new tool that helps traditional biology unravel some mysteries concerning life and living organisms on Earth. We use Einstein’s famous equation to explain how an unknown energy realm creates the material universe. We demonstrate how material existence precedes living existence and elucidate how non-living atoms transition to living molecules, Francis Crick’s faded dream that comes to reality. Finally, we expose the two types of Information available inside a cell to sustain life in living organisms and elaborate on a new formulation of the biogenesis theory.
