Abstract. Sickle cell disease (SCD) is an autosomal recessive genetic blood disorder that occurs when both alleles of the HBB gene have mutations, leading to the production of abnormal haemoglobin (HbS). The presence of HbS causes red blood cells (RBCs) to take on the distinctive sickle-shaped form associated with the disease. This, in turn, leads to blockages in blood vessels, decreased blood circulation, and organs’ damage. Traditional treatments such as blood transfusions and hydroxyurea offer relief but come with their own limitations and associated risks. Gene therapy has emerged as a promising paradigm shift in the quest to cure SCD, offering personalised solutions by targeting the genetic root of the disease. This review article explores the principles and recent advancements in gene therapy for SCD. However, before gene therapy can become the main curative strategy for this disease, several challenges need to be overcome including the need for long-term safety and efficacy evaluations. Ongoing research and innovation hold the promise of enhanced treatments and the potential for a widely available gene therapy, ultimately improving the quality of life for individuals living with SCD.

Decoding the DNA of Scat and the Application of Genetic Methodologies to Understanding Carnivore Diet
Charlotte E. Hacker, PhD
Abstract. Carnivore species are vital to ecosystem function and maintenance. One key component to understanding carnivore ecology and the most effective means of management is knowledge of dietary resource use. Traditional methods used to study carnivore diet, such as microhistology, have several technical and logistical shortcomings. These have hindered the quality and quantity of data that shape understanding of how carnivores exploit prey. Advances in genetic methodologies and their application to wildlife biology has transformed the manner in which information about species can be gained. DNA metabarcoding is one such example. With this approach, genetic sequences present in scat can be determined via next-generation sequencing and matched to reference databases, revealing the carnivore that deposited the scat and the prey it consumed. DNA metabarcoding has the ability to overcome many of the previous challenges associated with dietary analysis and works to advance and inform current knowledge surrounding carnivore ecology, predator-prey relationships, conflicts between carnivores and humans, and potential adaptability to large-scale landscape shifts. Its use has provided novel insights on numerous carnivore species to help inform research priorities and wildlife policies, including those living in unique fragile environments such as the Qinghai-Tibetan Plateau of China. The continued development and increased capacity of molecular dietary analysis via DNA metabarcoding has the promise to grossly improve carnivore conservation management strategies on a global scale.

Using spore-forming bacteria to treat cancer: recent advancements in clostridial-based therapies 💰
Raquel Rodrigues, PhD
Abstract. The use of bacteria in cancer therapy has emerged as a promising approach, offering unique advantages for targeted treatment and immunotherapy. This review paper explores some recent advances in the application of bacteria, particularly Clostridium species, in cancer therapy. For instance, the Clostridial-Directed Enzyme Prodrug Therapy (CDEPT) utilises non-pathogenic strains of Clostridium as carriers for targeted delivery of anti-cancer drugs to solid tumour cells. This strategy aims to minimise systemic side effects associated with traditional chemotherapy. Additionally, Clostridium novyi and Clostridium sporogenes present oncolytic properties and have shown potential for tumour regression in preclinical models. The engineering of these bacteria to produce cytokines, such as interleukin-12 (IL-12) and interleukin-2 (IL-2), further enhances their therapeutic potential by activating the immune system to target cancer cells. Clinical trials in humans have demonstrated the feasibility and safety of C. novyi-based therapies, and early results indicate potential efficacy in tumour regression. Overall, this review provides valuable insights into the multifaceted roles of bacteria, particularly Clostridium species, in cancer therapy, emphasizing their potential as targeted therapeutics and immunomodulators for improved cancer treatment outcomes.

All-natural 5-MeO-DMT sigma receptor 1 agonist and its therapeutic impact in mental and neurodegener-ative diseases through mitochondrial activation
Milena Batalla, PhD
Abstract. The sigma-1 receptor S1R is a chaperone that resides mainly at the mitochondrion-associated endoplasmic reticulum ER membrane MAM, it is considered a “pluripotent modulator” in living systems, plays a critical role in maintaining neuronal homeostasis and acts as a dynamic pluripotent modulator in living systems. Given its specific localization at the MAM, S1R plays a major role regulating mitochondrial function, it is a therapeutic target in mental and neurodegenerative diseases including Alzheimer’s disease, Parkinson’s disease. N,N Dimethyl Tryptamine DMT is the S1R endogen agonists and we review the role of all-natural 5-methoxi-N,N-dimethyltryptamine 5-MeO-DMT S1R agonist that produces high levels of ego dissolution or oceanic boundlessness higher ratings of satisfaction with life and lower ratings of depression and stress. In vitro the 5-Meo-DMT shows strong modulation of synaptic and cellular plasticity in neurons. 5-MeO-DMT neuropharmacological S1R agonist is implicated in cellular bioenergetics activation, antiapoptotic and mitochondrial regulation of epigenetic landscape in neurons. S1R has been considered as a controller of cell survival and differentiation in neurons. The pharmacological benefits of all-natural 5-MeO-DMT are currently under research. This review compendia results, highlighting the key molecular mechanisms of S1Rs on mitochondrial functions and epigenetic modifications involved in the health and sickness phenotype development, and describe the possible pharmacological use of all-natural 5-MeO-DMT to “rescue” patients from sickness phenotype through mitochondrial activation. We focus on all-natural 5-MeO-DMT its clinical therapeutic implications benefit long-term effects on mental health and well-being of the patient possibly reprogramming and remodeling the epigenome, particularly in mental and neurodegenerative diseases.

Bridging the gap: understanding the significance of catecholamines in neurochemistry and recent advances in their detection
Arnab Bhattacharya, PhD
Abstract. The neurochemistry of catecholamines plays a crucial and complex role in human memory, behavior, and cognition, while affecting other organs such as the lungs, heart, liver, and skin. Dopamine, norepinephrine, and epinephrine are three closely-related catecholamines that have been widely studied over the last seven decades for development of medications for life-threatening diseases. Other studies have also suggested a link between drug abuse and catecholamine levels. The determination of catecholamine levels in different parts of the human body has also been a hot topic for research in these years. HPLC, spectrophotometry, fluorescence, electrochemistry and other techniques have been used to quantify catecholamines in mostly in biological samples like serum and urine, although in vivo studies are also possible. This article attempts to present the research on catecholamines from the perspectives of their bodily functions, development of medications for diseases related to these, and the techniques used for their detection and quantification.

Intratumoural heterogeneity as a major challenge for cancer modelling and successful treatment 💰
Johanna Pruller, PhD
Abstract. Cancer heterogeneity refers to the fact that cancer cells are characterised by different genomic/transcriptomic/proteomic compositions, which often confer behavioural properties, such as enhanced drug resistance, survival and propensity to form metastasis. Modern methodology, such as single-cell barcoding, now allows a deeper look into this mechanic, and therefore a possibility to derive more efficient, new treatments. However, cell culture approaches are commonly used to evaluate those novel approaches, and the ability to faithfully model cancer heterogeneity is still in its infancy. Read More.

Biomimetic nanoparticles for cancer targeting and drug delivery
Sahil Malhotra, PhD
Abstract. Cellular membrane engineered nanoparticles (NPs) have shown immense potential for anti-cancer drug delivery applications. In principle, cell membrane of any type of cells can be processed to obtain purified cellular membrane which can self-assemble to form stable and highly robust nanovesicles. These nanovesicles retain lipid-bilayer architecture of host’s cells and much of the surface biomarkers and proteins are conserved during top-down approach. Interestingly, nanovesicles have exhibited long plasma circulation and appreciable tumour specific binding, which is largely suggestive of their biomimetic properties. Many pioneer studies have demonstrated their ability to encapsulate different chemotherapeutic agents and photosensitizers of varied chemical complexities, and releasing them in a triggered fashion. Additionally, the novel NPs system has been developed for cancer immunotherapy. The review discusses some of the important research and applications of cellular membrane derived nanovesicles for different forms of cancer therapy and their potential to be developed as personalized nanomedicine.

Therapies for sensory organ disorders
Rebecca L Bricker, PhD
Abstract. Sensory organ disorders, such as visual impairment, hearing loss, and olfactory dysfunction, affect a significant percentage of the population. There are no effective therapies to restore cell damage and tissue function to these sensory organs. Human pluripotent cells (hPSCs) have the potential to expand out to an unlimited number of cells and differentiate into any cell type of the body, and therefore have high potential to restore tissue function in transplantation cell therapies for sensory organ disorders. This review elaborates on the specific sensory cells for the vision, auditory, and olfactory tissues that were generated from hPSCs. It then describes the effectiveness of using hPSC-derived sensory progenitors in animal models of disease and what needs to be done next in order to progress. Read More.

Recognition of exosomes and their role in new technologies
Olesya Gusachenko, PhD
Abstract. Exosomes or, more broadly, small extracellular vesicles are produced by all cells. They contain an array of biologically active molecules by which exosomes can influence the extracellular environment and affect the properties of other cells. Recognition of their biological role has come a long way from the mere function in the disposal of cellular waste to a concept of universal intercellular vehicle mediating near and long-distance communication in normal and pathological states. As a result, in recent years exosomes have gained much interest in their potential exploitation for therapeutic use. This short review is aimed at presenting a brief exploration of the history of exosome recognition coupled with a snapshot of newly developing exosome-based technologies, touching upon some recent achievements and examples of application.

Recent insights into the use of invertebrates as indicators of habitat quality
by Rae Osborn, PhD
Abstract. Invertebrates are an important part of aquatic and terrestrial systems, and are, thus, useful as indicators of environmental changes. Habitat quality can be assessed by noting changes in species composition, and relative abundances, using various indices, and by alterations in physiology and morphology of what are known as indicator species. Research shows that invertebrates can be used to indicate if habitat conditions have changed, either worsened or improved. This is why identifying indicator species is crucial. This article covers some recent findings of how invertebrate organisms can be helpful in aquatic and terrestrial ecosystems in indicating ecosystem and habitat deterioration. We also discuss what makes a good indicator species and the types of taxa that have been used in this way. Read More.

Recent developments in microbiology
by Claire Cummins, BSc
Abstract. Research in microbiology is a dynamic and exciting field, and this review article outlines some recent significant developments within microbiology including using shotgun metagenomics to uncover the connection between diet and lifestyle and superbug infections, the current state of Ebola virus diagnostic tests, and the potential of treating superbug infections via innovative phage virus therapy as an alternative to antibiotics. This review also explores two studies using the CRISPR gene editing technique, which has been a revolution within microbiology. The first study undergoes genetic engineering of potatoes to improve their nutritional and industrial applications, which has important implications in improving food stability as well as bolstering production. The second study utilizes CRISPR to engineer bacteria to kill themselves on command, which is important to prevent the excessive spread bacteria that are used for a variety of applications from eating plastic waste in the environment to treating the diseased human gut. Engineering these so-called ‘kill switch’ allows these bacteria to be utilized for their intended purpose without growing uncontrollably in the environment or in the gut. Read More.

All-natural 5-MeO-DMT sigma receptor 1 agonist and its therapeutic impact in mental and neurodegener-ative diseases through mitochondrial activation
Milena Batalla, PhD
Abstract. The sigma-1 receptor S1R is a chaperone that resides mainly at the mitochondrion-associated endoplasmic reticulum ER membrane MAM, it is considered a “pluripotent modulator” in living systems, plays a critical role in maintaining neuronal homeostasis and acts as a dynamic pluripotent modulator in living systems. Given its specific localization at the MAM, S1R plays a major role regulating mitochondrial function, it is a therapeutic target in mental and neurodegenerative diseases including Alzheimer’s disease, Parkinson’s disease. N,N Dimethyl Tryptamine DMT is the S1R endogen agonists and we review the role of all-natural 5-methoxi-N,N-dimethyltryptamine 5-MeO-DMT S1R agonist that produces high levels of ego dissolution or oceanic boundlessness higher ratings of satisfaction with life and lower ratings of depression and stress. In vitro the 5-Meo-DMT shows strong modulation of synaptic and cellular plasticity in neurons. 5-MeO-DMT neuropharmacological S1R agonist is implicated in cellular bioenergetics activation, antiapoptotic and mitochondrial regulation of epigenetic landscape in neurons. S1R has been considered as a controller of cell survival and differentiation in neurons. The pharmacological benefits of all-natural 5-MeO-DMT are currently under research. This review compendia results, highlighting the key molecular mechanisms of S1Rs on mitochondrial functions and epigenetic modifications involved in the health and sickness phenotype development, and describe the possible pharmacological use of all-natural 5-MeO-DMT to “rescue” patients from sickness phenotype through mitochondrial activation. We focus on all-natural 5-MeO-DMT its clinical therapeutic implications benefit long-term effects on mental health and well-being of the patient possibly reprogramming and remodeling the epigenome, particularly in mental and neurodegenerative diseases.

Bridging the gap: understanding the significance of catecholamines in neurochemistry and recent advances in their detection
Arnab Bhattacharya, PhD
Abstract. The neurochemistry of catecholamines plays a crucial and complex role in human memory, behavior, and cognition, while affecting other organs such as the lungs, heart, liver, and skin. Dopamine, norepinephrine, and epinephrine are three closely-related catecholamines that have been widely studied over the last seven decades for development of medications for life-threatening diseases. Other studies have also suggested a link between drug abuse and catecholamine levels. The determination of catecholamine levels in different parts of the human body has also been a hot topic for research in these years. HPLC, spectrophotometry, fluorescence, electrochemistry and other techniques have been used to quantify catecholamines in mostly in biological samples like serum and urine, although in vivo studies are also possible. This article attempts to present the research on catecholamines from the perspectives of their bodily functions, development of medications for diseases related to these, and the techniques used for their detection and quantification.

Intratumoural heterogeneity as a major challenge for cancer modelling and successful treatment 💰
Johanna Pruller, PhD
Abstract. Cancer heterogeneity refers to the fact that cancer cells are characterised by different genomic/transcriptomic/proteomic compositions, which often confer behavioural properties, such as enhanced drug resistance, survival and propensity to form metastasis. Modern methodology, such as single-cell barcoding, now allows a deeper look into this mechanic, and therefore a possibility to derive more efficient, new treatments. However, cell culture approaches are commonly used to evaluate those novel approaches, and the ability to faithfully model cancer heterogeneity is still in its infancy. Read More.

Biomimetic nanoparticles for cancer targeting and drug delivery
Sahil Malhotra, PhD
Abstract. Cellular membrane engineered nanoparticles (NPs) have shown immense potential for anti-cancer drug delivery applications. In principle, cell membrane of any type of cells can be processed to obtain purified cellular membrane which can self-assemble to form stable and highly robust nanovesicles. These nanovesicles retain lipid-bilayer architecture of host’s cells and much of the surface biomarkers and proteins are conserved during top-down approach. Interestingly, nanovesicles have exhibited long plasma circulation and appreciable tumour specific binding, which is largely suggestive of their biomimetic properties. Many pioneer studies have demonstrated their ability to encapsulate different chemotherapeutic agents and photosensitizers of varied chemical complexities, and releasing them in a triggered fashion. Additionally, the novel NPs system has been developed for cancer immunotherapy. The review discusses some of the important research and applications of cellular membrane derived nanovesicles for different forms of cancer therapy and their potential to be developed as personalized nanomedicine.

Re-evaluating the role of antibodies in tuberculosis 💰
Pia Steigler, PhD
Abstract. Tuberculosis (TB) is a disease found in every country on Earth. About a quarter of the global population is estimated to be infected with Mycobacterium tuberculosis, the causative agent of TB, with over 10 million new TB cases reported annually. Currently, TB ranks as the second leading infectious killer after COVID-19. Research to develop novel interventions against TB represents a global health priority. TB research over the last several years focused on cellular immune responses, while the humoral response was largely neglected. This mini-review discusses evidence supporting a protective role of antibodies in TB, and a potential role of antibodies in TB vaccines and diagnosis. Read More.

Therapies for sensory organ disorders
Rebecca L Bricker, PhD
Abstract. Sensory organ disorders, such as visual impairment, hearing loss, and olfactory dysfunction, affect a significant percentage of the population. There are no effective therapies to restore cell damage and tissue function to these sensory organs. Human pluripotent cells (hPSCs) have the potential to expand out to an unlimited number of cells and differentiate into any cell type of the body, and therefore have high potential to restore tissue function in transplantation cell therapies for sensory organ disorders. This review elaborates on the specific sensory cells for the vision, auditory, and olfactory tissues that were generated from hPSCs. It then describes the effectiveness of using hPSC-derived sensory progenitors in animal models of disease and what needs to be done next in order to progress. Read More.

Recognition of exosomes and their role in new technologies
Olesya Gusachenko, PhD
Abstract. Exosomes or, more broadly, small extracellular vesicles are produced by all cells. They contain an array of biologically active molecules by which exosomes can influence the extracellular environment and affect the properties of other cells. Recognition of their biological role has come a long way from the mere function in the disposal of cellular waste to a concept of universal intercellular vehicle mediating near and long-distance communication in normal and pathological states. As a result, in recent years exosomes have gained much interest in their potential exploitation for therapeutic use. This short review is aimed at presenting a brief exploration of the history of exosome recognition coupled with a snapshot of newly developing exosome-based technologies, touching upon some recent achievements and examples of application.

Recent insights into the use of invertebrates as indicators of habitat quality
by Rae Osborn, PhD
Abstract. Invertebrates are an important part of aquatic and terrestrial systems, and are, thus, useful as indicators of environmental changes. Habitat quality can be assessed by noting changes in species composition, and relative abundances, using various indices, and by alterations in physiology and morphology of what are known as indicator species. Research shows that invertebrates can be used to indicate if habitat conditions have changed, either worsened or improved. This is why identifying indicator species is crucial. This article covers some recent findings of how invertebrate organisms can be helpful in aquatic and terrestrial ecosystems in indicating ecosystem and habitat deterioration. We also discuss what makes a good indicator species and the types of taxa that have been used in this way. Read More.

Recent developments in microbiology
by Claire Cummins, BSc
Abstract. Research in microbiology is a dynamic and exciting field, and this review article outlines some recent significant developments within microbiology including using shotgun metagenomics to uncover the connection between diet and lifestyle and superbug infections, the current state of Ebola virus diagnostic tests, and the potential of treating superbug infections via innovative phage virus therapy as an alternative to antibiotics. This review also explores two studies using the CRISPR gene editing technique, which has been a revolution within microbiology. The first study undergoes genetic engineering of potatoes to improve their nutritional and industrial applications, which has important implications in improving food stability as well as bolstering production. The second study utilizes CRISPR to engineer bacteria to kill themselves on command, which is important to prevent the excessive spread bacteria that are used for a variety of applications from eating plastic waste in the environment to treating the diseased human gut. Engineering these so-called ‘kill switch’ allows these bacteria to be utilized for their intended purpose without growing uncontrollably in the environment or in the gut. Read More.
