As a new form of regulated cell death,ferroptosis has unraveled the unsolicited theory of intrinsic apoptosis resistance by cancer cells.The molecular mechanism of ferroptosis depends on the induction of oxidative stress through excessive reactive oxygen species accumulation and glutathione depletion to damage the structural integrity of cells.Due to their high loading and structural tunability,nanocarriers can escort the delivery of ferro-therapeutics to the desired site through enhanced permeation or retention effect or by active targeting.This review shed light on the necessity of iron in cancer cell growth and the fascinating features of ferroptosis in regulating the cell cycle and metastasis.Additionally,we discussed the effect of ferroptosis-mediated therapy using nanoplatforms and their chemical basis in overcoming the barriers to cancer therapy.

The study aimed at assessing the physiochemical characteristics of rainwater in Warri and it environ was investigated. Pb, Zn, Cd, Cu and Cr concentrations in rainwater from roof and non-roof sources were determined using Atomic Absorption Spectrophotometry. Three geospatial locations comprising Jakpa, Udu, and Ubeji were selected based on prevailing anthropogenic activities. The rainwater samples were systematically collected from (aluminum) roof and non-roof sources for the months of April, June, and August and October 2022, treated and analyzed in the laboratory for sixteen physicochemical parameters. Results were statistically analyzed using ANOVA, and T-test for the determination of the level of relationships and variations across geospatial locations. Significant correlations (r = 0.72) exist between Cr in rainwater from roof and non-roof sources. Implying point-source contaminations and may be emanating from the influence of roof materials. Furthermore, high concentrations of Cd and Pb in roof source above WHO standards were mostly in Jakpa and Ubeji. Calculated Health Risk Index (HRI) for children and adult is greater than 1. The results showed that most samples from the locations are considered not safe (HRI > 1) especially for Cd, which means that there are potential health risks consuming rainwater from Jakpa, Udu and Ubeji. Therefore, there is need for prompt sensitization program to dissuade people from directly drinking rainwater from these locations.

The widespread outbreak of SARS-CoV-2 was declared a public health emergency by the World Health Organization and various governments worldwide.This prompted the implementation of stringent infection control measures to curb the spread of the virus.Amidst this,the medical community faced the challenge of treating the virus without specific therapies or a vaccine,leading to reliance on empirical treatment approaches.In this context,hydroxychloroquine,an antimalarial and antirheumatic drug,gained attention as a potential treatment option.Despite its theoretical benefits,such as inhibiting viral entry,reducing inflammation,and modulating immune responses,empirical studies yielded inconsistent results.Some indicated a potential for symptom relief,while others showed no significant improvement in patient outcomes.The initial enthusiasm waned as the lack of substantial evidence led to revoking its Emergency Use Authorization,and several clinical trials were prematurely halted.The review in question critically examines the factors contributing to the ineffectiveness of hydroxychloroquine in treating SARS-CoV-2 infection,highlighting the complexities of drug repurposing during a rapidly evolving pandemic.

Identifying a potential dietary non-pharmacological treatment to prevent cerebrovascular damage in Alzheimer's disease is crucial for alleviating cognitive decline in older adults and enhancing quality of life. This study featured the combined supplementation of soy lecithin (SL) and soy isoflavones (SIF)， using in vivo animal models， in vitro vascular ring preparation， and cell studies to investigate the potential advantages and mechanisms of SL combined with SIF on cognitive function and cerebrovascular health from multiple perspectives. The results show that Aβ can significantly induce learning and memory impairment in rats， as well as pathological changes in brain blood vessels， exacerbating damage to cerebral vasodilation function and subsequently reducing cerebral blood flow (CBF) in the brain. The above-mentioned phenomena induced by Aβ can be significantly improved by the combined intervention of SL and SIF. Further research has revealed that the combined intervention of SL and SIF can reverse the downregulation of the PI3K/PIP3/PDK-1/Akt/eNOS signaling pathway and phosphorylated protein expression induced by Aβ in rat brain vascular tissues and bEND.3 cells. Silencing PDK-1 expression in bEND.3 cells showed that the upregulation effect of SL and SIF on Akt and eNOS disappeared. Here we find that prophylactically supplementation with SL in conjunction with SIF appears to effectively activate the PI3K/PIP3/PDK-1/Akt/eNOS pathway within cerebral vascular. This activation improves cerebrovascular vasodilation， offering potential protective effects for both cerebral vascular health and cognitive function.

引用

Journal of Forensic Science and Medicine 2024年第1期10卷 28-33页

作者： Chandan Bandyopadhyay Prabir Chandra Paul Prabhas Chandra Chakraborty department of Forensic and State Medicine Medical CollegeKolkataWest BengalIndia department of Pathology Jagannath Gupta Institute of Medical Science and HospitalKolkataWest BengalIndia department of Forensic Medicine and toxicology NRS Medical College and HospitalKolkataand M.G.M Medical College and L S.K HospitalKishanganjBiharIndia

Background and Objectives:The cases of apparent natural deaths are encountered in the hospital casualties who are noted dead at the time of the first medical attention and as such are labeled as“Brought Dead.”These include the cases of sudden death,unexplained death,and unattended death.The cause of such deaths is reported in the literature to emanate principally from the cardiovascular system,though there are some documented geographical,racial,and other variations.In the present study,we endeavored to detect the cause of such natural deaths in terms of the disease and the organ system involved,in the deceased individuals of the contemporary Bengali population,with cases due to obvious unnatural causes being excluded.Materials and Methods:An observational,cross-sectional study with 105(n=105,male:89,female:16)study subjects of age group of 20-80 years,selected by systemic random sampling,from the brought dead subjects coming to the mortuary of the NRS Medical College and Hospital for medicolegal autopsy from April 2011 to March 2012,excluding cases having a history of the obvious unnatural event.Organ system-wise gross examination was done,followed by tissue sampling for histopathological examination.The case-wise findings were tabulated and analyzed for descriptive statistics using SPSS software.Results:In the present study,89 cases were male(84.8%)and 16 cases were female(15.2%),which reflects a male:female ratio of 5.56:1.The dead bodies are mostly recovered from the footpaths(47 cases,44%).Sixty-four(61%)cases are of known identity.In 54 cases out of 105(51.4%),morbid pathology is detected in the respiratory system(RS),lobar pneumonia,and cavitary pulmonary tuberculosis being the most frequent disease entity,in both genders.Fifty-one years-sixty-five years is found to be the most commonly affected age group,in both genders.Interpretation and Conclusions:The present study shows that the most common organ system involved in brought dead cases is the RS,which is supported by a few Indian studies.

Worldwide,the incidence of major depressive disorder(MDD)is increasing annually,resulting in greater economic and social burdens.Moreover,the pathological mechanisms of MDD and the mechanisms underlying the effects of pharmacological treatments for MDD are complex and unclear,and additional diagnostic and therapeutic strategies for MDD still are needed.The currently widely accepted theories of MDD pathogenesis include the neurotransmitter and receptor hypothesis,hypothalamicpituitary-adrenal(HPA)axis hypothesis,cytokine hypothesis,neuroplasticity hypothesis and systemic influence hypothesis,but these hypothesis cannot completely explain the pathological mechanism of MDD.Even it is still hard to adopt only one hypothesis to completely reveal the pathogenesis of MDD,thus in recent years,great progress has been made in elucidating the roles of multiple organ interactions in the pathogenesis MDD and identifying novel therapeutic approaches and multitarget modulatory strategies,further revealing the disease features of MDD.Furthermore,some newly discovered potential pharmacological targets and newly studied antidepressants have attracted widespread attention,some reagents have even been approved for clinical treatment and some novel therapeutic methods such as phototherapy and acupuncture have been discovered to have effective improvement for the depressive symptoms.In this work,we comprehensively summarize the latest research on the pathogenesis and diagnosis of MDD,preventive approaches and therapeutic medicines,as well as the related clinical trials.

The microbiota-gut-brain axis(MGBA)has emerged as a key prospect in the bidirectional communication between two major organ systems:the brain and the gut.Homeostasis between the two organ systems allows the body to function without disease,whereas dysbiosis has long-standing evidence of etiopathological conditions.The most common communication paths are the microbial release of metabolites,soluble neurotransmitters,and immune cells.However,each pathway is intertwined with a complex one.With the emergence of in vitro models and the popularity of three-dimensional(3D)cultures and Transwells,engineering has become easier for the scientific understanding of neurodegenerative diseases.This paper briefly retraces the possible communication pathways between the gut microbiome and the brain.It further elaborates on three major diseases:autism spectrum disorder,Parkinson’s disease,and Alzheimer’s disease,which are prevalent in children and the elderly.These diseases also decrease patients’quality of life.Hence,understanding them more deeply with respect to current advances in in vitro modeling is crucial for understanding the diseases.Remodeling of MGBA in the laboratory uses many molecular technologies and biomaterial advances.Spheroids and organoids provide a more realistic picture of the cell and tissue structure than monolayers.Combining them with the Transwell system offers the advantage of compartmentalizing the two systems(apical and basal)while allowing physical and chemical cues between them.Cutting-edge technologies,such as bioprinting and microfluidic chips,might be the future of in vitro modeling,as they provide dynamicity.
