Prostate cancer is a public health problem in Senegal. It is one of the most common cancers in men and can be detected early by PSA measurement and confirmed by the pathological study which specifies the histological type and evaluates the histoprognostic scores (Gleason and pTNM). We did not find any anatomopathological study highlighting a link between the PSA t rate and histoprognostic Gleason scores in Senegal. Objective: We carried out this work aimed at determining whether there is a correlation between the PSA t rate and the histoprognostic Gleason score, in our context. Methodology: This is a retrospective, descriptive and analytical study conducted from January 2013 to October 2021, based on histologically proven prostate cancer cases with a specified PSA level, diagnosed in the pathological anatomy and cytology laboratory of Aristide Le Dantec hospital. Results: We identified 654 cases of prostate cancer. The average age was 68.59 ± 5.8 years with extremes of 40 years to 92 years. More than half of our cohort presented a clinical stage T2c, i.e. 56.94%. The average prostate volume on ultrasound was 81.81 ± 66 cc. The median PSA t was 110.5 ng/ml, with extremes ranging from 2 ng/ml to 74,770 ng/ml. Prostatic adenocarcinoma was the only histological type found in our patients. There was a predominance of Gleason score 6 (PICU grade group 1) observed in 35.17% of patients. Well-differentiated cancers were predominant and represented 35.17%. There was a statistically significant positive correlation between PSA t level and Gleason score (Spearman’s Rho = 0.305, p = 0.000). Conclusion: This study shows that in the Senegalese population, in patients with prostate cancer, the higher the PSA t level rises above normal, the higher the Gleason score tends to be.

The hypothalamic–pituitary–adrenal(HPA) axis is a critical component of the neuroendocrine system,playing a central role in regulating the body's stress response and modulating various physiological processes. Dysregulation of HPA axis function disrupts the neuroendocrine equilibrium, resulting in impaired physiological functions. Acupuncture is recognized as a non-pharmacological type of therapy which has been confirmed to play an important role in modulating the HPA axis and thus favorably targets diseases with abnormal activation of the HPA axis. With numerous studies reporting the promising efficacy of acupuncture for neuroendocrine disorders, a comprehensive review in terms of the underlying molecular mechanism for acupuncture, especially in regulating the HPA axis, is currently in need. This review fills the need and summarizes recent breakthroughs, from the basic principles and the pathological changes of HPA axis dysfunction, to the molecular mechanisms by which acupuncture regulates the HPA axis. These mechanisms include the modulation of multiple neurotransmitters and their receptors, neuropeptides and their receptors, and microRNAs in the paraventricular nucleus,hippocampus, amygdala and pituitary gland, which alleviate the hyperfunctioning of the HPA *** review comprehensively summarizes the mechanism of acupuncture in regulating HPA axis dysfunction for the first time, providing new targets and prospects for further exploration of acupuncture.

Background: Prostate cancer, the most common male cancer, represents a real public health problem in terms of its frequency and severity in different countries around the world. It disproportionately affects people of African descent wherever they live in the world [1]. To the best of our knowledge, its extent and particularities in the African environment are not well known. Objective: To determine the epidemiological and histopathological profile of prostate cancer in the CUK anatomopathology department. Methodology: This is a retrospective study conducted at the University Clinics of Kinshasa Anapathology Department from January 1, 2015 to December 31, 2022, a period of 8 years. Word processing and tables were entered using the Hp brand computer, with Microsoft Office WORD 2016 software. Data analysis was performed with SPSS version 22.0 software. Results were presented in tables and figures. Results: Prostate was diagnosed in 132 cases, i.e. 1.58% of all CUK laboratory analyses and 8% of cancers diagnosed. The age group most affected was 66-75 years, i.e. 59% of all subjects. Adenocarcinoma was the most frequent histological type, and biopsy dominated in 111 cases (84.1%). Conclusion: Prostate cancer is a real public health problem. Worldwide, and in the Democratic Republic of Congo, it is the most frequently diagnosed cancer in men, and the leading cause of cancer-related death in men. In the DRC, because of the delay in consulting our patients and the weakness of systematic screening, patients are seen at an advanced stage of the disease. Treatment is multidisciplinary, involving surgery, radiotherapy and chemotherapy (including targeted therapies). Patient awareness and screening campaigns will help to considerably reduce the delay in diagnosis and the morbidity and mortality associated with prostate cancer.

With increasing age,humans become more susceptible to the onset of neurodegenerative diseases(NDs),and among these,Alzheimer's disease(AD)is the most frequent(Nicoletti et al.,2023).NDs are primarily characterized by neuronal loss and atrophy,but also by lesions involving the cerebral and/or cardiovascular system(Balistreri,2021).Lesions such as macroinfa rcts,microinfarcts,hemorrhages,white matter lesions,atherosclerosis,and arteriolosclerosis have also been significantly described in the preclinical stages of cognitive impairment characterizing NDs(Mariani et al.,2007).

Porcine enteric alphacoronavirus infection increases lipid droplet accumulation to facilitate the virus replication

Coronaviruses are widely transmissible between humans and animals, causing diseases of varying severity. Porcine enteric alphacoronavirus(PEAV) is a newly-discovered pathogenic porcine enteric coronavirus in recent years, which causes watery diarrhea in newborn piglets. The host inflammatory responses to PEAV and its metabolic regulation mechanisms remain unclear, and no antiviral studies have been reported. Therefore, we investigated the pathogenic mechanism and antiviral drugs of PEAV. The transcriptomic analysis of PEAV-infected host cells revealed that PEAV could upregulate lipid metabolism pathways. In lipid metabolism, steady-state energy processes, which can be mediated by lipid droplets(LDs), are the main functions of organelles. LDs are also important in viral infection and inflammation. In infected cells, PEAV increased LD accumulation, upregulated NF-κB signaling, promoted the production of the inflammatory cytokines IL-1β and IL-8, and induced cell death. Inhibiting LD accumulation with a DGAT-1 inhibitor significantly inhibited PEAV replication, downregulated the NF-κB signaling pathway, reduced the production of IL-1β and IL-8, and inhibited cell death. The NF-κB signaling pathway inhibitor BAY11-7082 significantly inhibited LD accumulation and PEAV replication. Metformin hydrochloride also exerted anti-PEAV effects and significantly inhibited LD accumulation, downregulated the NF-κB signaling pathway, reduced the production of IL-1β and IL-8, and inhibited cell death. LD accumulation in the lipid metabolism pathway therefore plays an important role in the replication and pathogenesis of PEAV, and metformin hydrochloride inhibits LD accumulation and the inflammatory response to exert anti-PEAV activity and reducing pathological injury. These findings contribute new targets for developing treatments for PEAV infections.

Substrate stiffness is a microenvironment with a certain stiffness constructed by the extracellular matrix and adjacent cells, which plays an important role in the growth and development of cells and tissue formation. Studies have indicated that the stiffness of the brain is about 0.1–1 kPa. The physiological and pathological processes of the nervous system are mediated by the substrate stiffness that the neurons suffer. However, how substrate stiffness regulates these processes remains to be studied. Culturing neurons on substrates with different stiffness in vitro is one of the best methods to study the role of stiffness in regulating neuronal development and activity. In this study, by changing the preparation time and the activation time of polyacrylamide gel, we provide an improved method that achieves a low toxic substrate environment for better primary neuron adhesion and development. Hope that this method is convenient for those studying the role of substrate stiffness in neurons.
