Kukoamine A alleviates nephrolithiasis by inhibiting endogenous oxalate synthesis via the IL-6/JAK/STAT3/DAO signaling pathway

BackgroundThe recurrent nature and socioeconomic burden of nephrolithiasis demand effective treatments. Delineating the crosstalk between inflammatory processes and the endogenous oxalate metabolism pathway, which underpins nephrolithiasis pathogenesis, is essential for advancing treatment strategies. PurposeWe aim to screen therapeutic Chinese herbal remedies and their bioactive constituents for kidney stone treatment using a fruit fly model, followed by efficacy and mechanism validation in a rodent nephrolithiasis model as well as in vitro human cell culture model. Study design and methodsWe developed a fruit fly model to screen for efficient traditional Chinese medicine herbs and their active compounds for kidney stone treatment. Candidate active compounds from efficient herbs were separated and identified by solid-phase chromatography coupled with LC-MS analysis. Fruit fly genetic tools were employed to manipulate the expression of related genes to explore the therapeutic mechanisms of the Lycii Cortex and kukoamine A (KuA). To confirm the therapeutic effects and mechanisms of KuA for mammalian nephrolithiasis, mouse model of glyoxylate-induced kidney stone and human renal tubular cells were used. The therapeutic role of kukoamine A in nephrolithiasis was evaluated by assessing tubular injury, crystal deposition, and adhesion. The level of expression and phosphorylation in cells and mice was assessed using RT-qPCR and western blot. ResultsOur findings indicate that Lycii Cortex potently inhibits calcium oxalate stone formation via activation of the JNK/Upd3/JAK/STAT signaling cascade, resulting in diminished endogenous oxalate synthesis by downregulating D-amino acid oxidase (DAO) gene expression, predominantly in fruit fly Malpighian tube stellate cells. KuA was identified as the principal bioactive constituent mediating these effects. Both mouse models and human cell assays confirmed KuA's efficacy in preventing calcium oxalate nephrolithiasis in mammals, through hepatic JAK/STAT3 pathway activation and upregulation of IL-6, culminating in reduced urinary crystal deposition. ConclusionOur research underscores the potential of kukoamine A as a lead compound in treating nephrolithiasis and reveals the interplay between the IL-6/JAK/STAT3 inflammatory pathway and endogenous oxalate metabolism in nephrolithiasis pathogenesis. Additionally, it highlights the utility of the fruit fly model as a powerful tool for deciphering the therapeutic mechanisms of traditional Chinese herbs.

Food Supplement Based on L-Arginine and Grape Extract for the Control of Blood Pressure

The treatment of most patients with elevated blood pressure requires drug therapy, as well as lifestyle measures to achieve optimal blood pressure control. There are numerous side effects resulting from the use of these drugs: from the persistent dry cough of ACE inhibitors, to the headache, dizziness and tiredness of CCBs, to the slow heartbeat and sleep disturbances of betablockers. Scientific research in recent years is focusing attention on safer alternative therapeutic remedies, possibly of natural origin, also in support of classic pharmacological therapies, in order to reduce the doses of active ingredients and, consequently, their side effects. The present project aims to clinically test a nutraceutical product consisting of a formulation based on L-arginine and grape pomace extract of the Aglianico cultivar microencapsulated into maltodextrin. The formulation acts by: favoring the NO-soluble GC (sGC)-cGMP pathway; with an antioxidant effect on the heme group Fe+2, with a greater production of cGMP. The study involves the enrollment of 80 patients in 3 internal medicine units adhering to FADOI Campania. The treatment involves 1 tablet/ day. Project duration for each UOC: 80 days.

Epigenetic Cross-Talk Between Sirt1 and Dnmt1 Promotes Axonal Regeneration After Spinal Cord Injury in Zebrafish.

Though spinal cord injury (SCI) causes irreversible sensory and motor impairments in human, adult zebrafish retain the potent regenerative capacity by injury-induced proliferation of central nervous system (CNS)-resident progenitor cells to develop new functional neurons at the lesion site. The hallmark of SCI in zebrafish lies in a series of changes in the epigenetic landscape, specifically DNA methylation and histone modifications. Decoding the post-SCI epigenetic modifications is therefore critical for the development of therapeutic remedies that boost SCI recovery process. Here, we have studied on Sirtuin1 (Sirt1), a non-classical histone deacetylase that potentially plays a critical role in neural progenitor cells (NPC) proliferation and axonal regrowth following SCI in zebrafish. We investigated the role of Sirt1 in NPC proliferation and axonal regrowth in response to injury in the regenerating spinal cord and found that Sirt1 is involved in the induction of NPC proliferation along with glial bridging during spinal cord regeneration. We also demonstrate that Sirt1 plays a pivotal role in regulating the HIPPO pathway through deacetylation-mediated inactivation of Dnmt1 and subsequent hypomethylation of yap1 promoter, leading to the induction of ctgfa expression, which drives the NPC proliferation and axonal regrowth to complete the regenerative process. In conclusion, our study reveals a novel cross-talk between two important epigenetic effectors, Sirt1 and Dnmt1, in the context of spinal cord regeneration, establishing a previously undisclosed relation between Sirt1 and Yap1 which provides a deeper understanding of the underlying mechanisms governing injury-induced NPC proliferation and axonal regrowth. Therefore, we have identified Sirt1 as a novel, major epigenetic regulator of spinal cord regeneration by modulating the HIPPO pathway in zebrafish.

Anaemia prevention among pregnant women: Views and experiences of pregnant women and antenatal care providers in Accra, Ghana

Background and ObjectiveAnaemia among pregnant women is a public health challenge in Ghana. Although there isa national programme of routine iron-folic acid (IFA) supplementation, coverage issuboptimal. The current study explored experiences and perceptions of anaemiaprevention, and IFA use among pregnant women and antenatal care providers at twohospitals in Accra, Ghana, for enhancing the supplementation programme.MethodsUtilizing a qualitative approach, 6 focus group discussions with 48 purposively selectedpregnant women, and 10 in-depth interviews with care providers in two hospitals wereconducted. Interviews were transcribed verbatim. Using both deductive and inductiveapproaches, priori themes that informed the design of the interview guides, and emergingcodes from transcripts were used in data analysis.ResultsIn both hospitals, pregnant women reported awareness of anaemia and identified poorquality diets and failure to take IFA as the predominant causes. Regular IFAsupplementation, and consumption of fruits, vegetables, and animal-source foods wereindicated as the main anaemia remedies by the pregnant women. Turkey berry, beetroot,and hibiscus flower were also reported as therapeutic remedies for anaemia. IFA use waslinked with improved appetite, haemoglobin, and health status of mothers and their fetus.Both providers and pregnant women indicated that IFA is freely accessible throughgovernment facilities but may also be purchased. IFA supplements are recommended to betaken daily but three times for treatment; however, non-adherence to the recommendedfrequency was reported. This was attributed to adverse reactions including nausea andvomiting, unanticipated cost of increased appetite, forgetfulness to take IFA,misperceptions about adverse effects of IFA, transportation cost to access IFA, and longwaiting time at hospitals. Community-level focused antenatal care, follow-up visits, andphone calls were reported by providers as strategies to improve IFA uptake. Communitysensitization, enhanced access to IFA, and participatory approach to ANC services weresuggested by pregnant women as strategies for improving IFA uptake.ConclusionsFood insecurity and misperceptions about IFA should be addressed as part of efforts toaddress low IFA adherence and high maternal and child anaemia rates in Ghana.

Isolation and characterization of Chlamydia felis and its pathogenesis in cats

Feline upper respiratory tract disease (URTD) is a common but complicated disease that occurs in domestic cats, worldwide. 396 cats in Guangxi Province, China were screened for URTD-associated pathogens from March 2022 to August 2023. Mycoplasma felis was found to be the most prevalent infectious agent with a positivity rate of 24.75 %, followed by feline calicivirus (FCV), Chlamydia felis, feline herpesvirus 1 (FHV-1) and feline influenza A virus (FeIAV) with rates of 15.91, 11.62, 5.56 and 1.52 %, respectively. In particular, C. felis and M. felis were found in 13 of 55 co-infected cats. Of the 46 C. felis-positive samples, one strain, named as GXNN36, was successfully isolated using chicken embryos and it was characterized both in vivo and in vitro. For the cat studies, both high- and low-dose challenged groups showed severe conjunctivitis, accompanied by transient fever and respiratory symptoms. C. felis replicated well in turbinate, trachea and lung tissues with high copy numbers and the infection subsequently spread to the livers, spleens, pancreas, kidneys, hearts and intestines. These findings will help our understanding of the role of C. felis in feline URTD and provide a valuable model to evaluate the efficacy of vaccines and therapeutic remedies in the future.

Stem Cell Interventions in the Treatment of Alzheimer's Disease.

Alzheimer's disease (AD), an inexorable neurodegenerative ailment marked by cognitive impairment and neuropsychiatric manifestations, stands as the foremost prevailing form of dementia in the geriatric population. Its pathological signs include the aggregation of amyloid proteins, hyperphosphorylation of tau proteins, and the consequential loss of neural cells. The etiology of AD has prompted the formulation of numerous conjectures, each endeavoring to elucidate its pathogenesis. While a subset of therapeutic agents has displayed clinical efficacy in AD patients, a significant proportion has encountered disappointment. Notably, the extent of neural cell depletion bears a direct correlation with the disease's progressive severity. However, the absence of efficacious therapeutic remedies for neurodegenerative afflictions engenders a substantial societal burden and exerts a notable economic toll. In the past two decades, the realm of regenerative cell therapy, referred to as stem cell therapy, has unfolded as an avenue for the exploration of profoundly innovative approaches to treat neurodegenerative conditions. This promise is underpinned by the remarkable capacity of stem cells to remediate compromised neural tissue by means of cell replacement, to cultivate an environment conducive to regeneration, and to shield extant healthy neuronal and glial components from further degradation. Thus, this review aims to delve into the current knowledge of stem cell-based therapies and future possibilities in this domain.

Alpha-amylase and Alpha-glucosidase Inhibitory Activities of Philippine Indigenous Medicinal Plants

In the Philippines, medicinal plants still provide the first line of therapeutic remedies and their reported efficacy in traditional treatments provides an opportunity for drug discovery and development. The study aimed to evaluate in vitro commonly used Philippine medicinal plants for their alpha-amylase and alpha-glucosidase inhibitory activities as potential sources of antidiabetic agents. The study emphasised the inhibitory activities of 54 medicinal plants against α-amylase and α-glucosidase enzymes. The findings revealed 7 medicinal plants with the highest alpha-glucosidase inhibitory activity of ≥ 50% and 3 with alpha-amylase inhibitory activity of ≥ 20%. Ethyl acetate extract of Cycas sp. exhibited the highest α-glucosidase inhibitory activity with 83.87% ± 1.52 followed by the aqueous extract of cf. Calyptranthera sp. With 82.07% ± 0.14 with Acarbose as the reference standard (99.71% ± 0.63) at 10µg/mL (w/v) concentration. For the alpha-amylase inhibitory assay, the highest bioactivity was observed in ethyl acetate extract of Curcuma longa L. (39.44% ± 1.56) with Acarbose as the reference standard (51.59% ± 0.98) at 10µg/mL (w/v) concentration. These findings suggest the potential of the above-mentioned plants as sources of alpha-amylase and alpha-glucosidase inhibitors that may be used as antidiabetic agents.

Natural Aphrodisiacs: Traditional Use, Mechanism of Action, Clinical Efficacy, and Safety

Abstract: Since time immemorial, people have been trying to influence different aspects of their sexuality. They seek ways to increase sexual activity or sexual desire in themselves and their partners. In addition to resorting to all sorts of mystical rituals, people were looking for various effects from the use of natural raw materials. Some plant, animal, or fungal products have been shown to affect libido, sexual arousal, erectile function, orgasm or erogenous zone sensitivity. Such substances have been called "aphrodisiacs" in honor of the ancient Greek goddess of love - Aphrodite. Most often, aphrodisiacs were taken orally, but some were smoked while others applied to the genitals. In modern clinical practice, phosphodiesterase type 5 inhibitors are used. These are substances, which enhance erection and prevent detumescence in the presence of sexual arousal. Another group of drugs is selective serotonin reuptake inhibitors, which reduce sexual arousal and sexual afferent from the genitals, thus preventing the premature onset of orgasm in men and prolonging sexual intercourse. However, drugs from other pharmacological groups have not found widespread clinical application. Another issue now is a trend among people taking drugs of natural origin, therefore, all kinds of traditional aphrodisiacs are actively used to the present day. Very little is known about almost all of them. Clinical trials are in most cases limited to a few, often not randomized, studies. In this regard, it is very difficult to evaluate the adequate therapeutic and toxic doses of remedies. The situation is complicated by the fact that those few clinical studies were based on questionnaires, that is, the indicators taken into statistical calculations were extremely subjective. Moreover, it was uncertain whether all patients could adequately assess their dynamics in terms of parameters such as sexual satisfaction, or clearly distinguish between libido and sexual arousal. Since the majority of the studies were not blinded, a psychogenic influence on the results of the investigations could not be eliminated, which in the sexual area may be huge. It is worth emphasizing the toxicity of many traditional aphrodisiacs. Of course, there is a serious deficit in the spectrum of pharmacotherapy for sexual disorders. Perhaps further large, randomized, placebo-controlled trials would add some of the traditional aphrodisiacs or their modifications to the arsenal of the clinical specialist.

What makes SARS-CoV-2 unique? Focusing on the spike protein.

Severe acute respiratory syndrome-related coronavirus 2 (SARS-CoV-2) seriously threatens public health and safety. Genetic variants determine the expression of SARS-CoV-2 structural proteins, which are associated with enhanced transmissibility, enhanced virulence, and immune escape. Vaccination is encouraged as a public health intervention, and different types of vaccines are used worldwide. However, new variants continue to emerge, especially the Omicron complex, and the neutralizing antibody responses are diminished significantly. In this review, we outlined the uniqueness of SARS-CoV-2 from three perspectives. First, we described the detailed structure of the spike (S) protein, which is highly susceptible to mutations and contributes to the distinct infection cycle of the virus. Second, we systematically summarized the immunoglobulin G epitopes of SARS-CoV-2 and highlighted the central role of the nonconserved regions of the S protein in adaptive immune escape. Third, we provided an overview of the vaccines targeting the S protein and discussed the impact of the nonconserved regions on vaccine effectiveness. The characterization and identification of the structure and genomic organization of SARS-CoV-2 will help elucidate its mechanisms of viral mutation and infection and provide a basis for the selection of optimal treatments. The leaps in advancements regarding improved diagnosis, targeted vaccines and therapeutic remedies provide sound evidence showing that scientific understanding, research, and technology evolved at the pace of the pandemic.

Phytochemical screening, total phenolics, total flavonoids, total tannins, antioxidant activities, and α-glucosidase inhibition of ethanolic leaf extracts from 37 cultivars of Antidesma puncticulatum Miq.

Introduction: Antidesma puncticulatum Miq., commonly known as Mao-Luang in Thailand, is a medicinal plant widely renowned for its abundance of bioactive compounds with diverse pharmacological properties. This study investigated the phytochemical components, antioxidant potentials, and α-glucosidase inhibitory activity of ethanolic leaf extracts from 37 cultivars of A. puncticulatum. Methods: The leaves of 37 different varieties of A. puncticulatum were dried, finely ground, and then extracted using ethanol. The phytochemical screening, total amounts of phenolics, flavonoids, and tannins of the extracts were assessed. To evaluate their antioxidant potential, the extracts were subjected to the 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2’-azinobis (3-ethylbenzthiazoline-6-sulfonic acid) (ABTS), and the ferric reducing antioxidant power (FRAP) Assays. In addition, standard in vitro methods were used to determine the α-glucosidase-inhibitory activity of the extracts. Results: Five phytochemical classes were detected in high concentrations in all of the extracts. Total phenolics, flavonoids, and tannins contents were in the range of 9.86-26.75 mg gallic acid equivalent (GAE)/g dry extract, 8.10-16.18 mg catechin equivalent (CE)/g dry extract, and 14.83-33.67 mg CE/g dry extract, respectively. According to DPPH, ABTS, and FRAP assay results, the antioxidant activities of the extracts were 5.10-9.07, 0.73-2.12, and 2.06- 4.01 mg ascorbic acid equivalent antioxidative capacity (AEAC)/g crude extract, respectively. Interestingly, the crude extracts from A. puncticulatum were more effective as α-glucosidase inhibitors than acarbose, with IC50 values ranging from 1.26 to 25.07 µg/mL. Conclusion: The ethanolic leaf extracts of A. puncticulatum were potent sources of phytochemicals with antioxidant and antidiabetic properties. Therefore, more research is needed to substantiate their potential applications as therapeutic remedies for diabetes.

Evaluation of the cognitive enhancing properties of diosmin in lipopolysaccharide‐induced memory impairment in mice

AbstractBackgroundCognitive impairment is a major feature of many neurodegenerative disorders such as Alzheimer’s disease, dementia etc. The progressive cognitive decline in Alzheimer’s disease (AD) can be attributed to the fact that current anti‐Alzheimer’s drug only treat AD symptoms without completely reversing cognitive impairment in AD patients. Therefore, it is imperative to develop new therapeutic remedies that can improve memory and ameliorate cognitive impairment in AD patients. Disomin is a flavone with antioxidant, anti‐inflammatory and anti‐apoptotic properties. This study evaluated the neuroprotective effects of diosmin on LPS‐induced cognitive impairment in mice.MethodThirty‐six Swiss mice were randomly divided into six groups (n = 6). Group 1 received vehicle, group 2 received vehicle, groups 3 to 5 received diosmin (50, 100 and 200 mg/kg, p.o.) respectively group 6 received donepezil (50 mg/kg, p.o.). Sixty minutes after the treatment with the vehicle/Diosmin/Donepezil, lipopolysaccharide (LPS) (250ug/kg, i.p.) was administered daily to groups 2 to 6 for seven days. Twenty‐four hours after treatment on day 7, mice were subjected to Y‐maze test and the Novelty object recognition test (NORT) to assess their spatial and non‐spatial working memory. Subsequently, the mice were sacrificed and their brain samples were harvested for biochemical analysis (TNF‐alpha, Interferon gamma and interleukin‐12), immunohistochemical examinations (Amyloid beta, BDNF, IBA‐1, NLRP3 expression) and Golgi staining procedure for morphological alterations.ResultOur data shows that diosmin increased percentage alternation in Y‐maze test and discrimination ratio in NORT compared with the control group. Diosmin significantly (p<0.05) decreased TNF‐alpha, Interferon gamma and interleukin‐12 and reduced neurodegeneration in the CA1 region of the hippocampus & dendate gyrus when compared with the control group.ConclusionDiosmin reversed LPS‐induced cognitive impairment, which can be attributed to its neuroprotective and anti‐inflammatory properties.

Bioactivity of the Genus Turnera: A Review of the Last 10 Years.

Turnera is a genus of plants whose biological activity has been widely studied. The importance of this genus, particularly Turnera diffusa, as a source of treatment for various conditions is evidenced by the large number of new studies that have evaluated its biological activity. Accordingly, the objective of this review was to compile the information published in the last ten years concerning the biological activities reported for Turnera spp. The present work includes 92 publications that evaluate 29 bioactivities and toxicological and genotoxic information on five species of this genus. Among the pharmacological effects reported, the antioxidant, hepatoprotective, neuroprotective, hypoglycemic, and aphrodisiac activities seem more promising. Phytochemicals and standardized plant extracts could offer alternative therapeutic remedies for various diseases. Although several flavonoids, cyanogenic glycosides, monoterpenoids, triterpenoids, and fatty acids have been isolated for Turnera plants, future research should focus on the identification of the main active principles responsible for these pharmacological activities, as well as to perform clinical trials to support the laboratory results.

DAYTIME RESTING ACTIVITY OF AEDES AEGYPTI AND CULEX QUINQUEFASCIATUS POPULATIONS IN NORTHERN MEXICO.

Aedes aegypti and Culex quinquefasciatus are disease vectors distributed throughout much of the world and are responsible for a high burden of vector-borne disease, which has increased during the last 2 decades. Most pathogens vectored by these mosquitoes do not have therapeutic remedies; thus, combating these diseases is dependent upon vector control. Improvements in vector control strategies are urgently needed, but these hinge on understanding the biology and ecology of Ae. aegypti and Cx. quinquefasciatus. Both species have been extensively investigated, but further knowledge on diel resting activity of these vectors can improve vector surveillance and control tools for targeting resting vector populations. From April to December 2021, we determined outdoor daytime resting habits of Ae. aegypti and Cx. quinquefasciatus male, female, and blood-fed female populations in Reynosa, Mexico, using large red odor-baited wooden box traps. The daytime resting activity for Ae. aegypti males, females, and blood-fed females was restricted to a period between 0900 h and 1300 h, with a peak at 0900 h, while the resting activity of Cx. quinquefasciatus male, female, and blood-fed females was between 0700 h and 1100 h, with a peak at 0700 h. A generalized additive model was developed to relate relative humidity and temperature to resting Cx. quinquefasciatus and Ae. aegypti male, female, and blood-fed populations caught in traps. This study advances the understanding of outdoor resting behavior for 2 important vector mosquito species and discusses future studies to fill additional knowledge gaps.

ANTIOXIDANT AND INHIBITORY EFFECT OF SELECTED GHANAIAN VEGETABLES ON NITRIC OXIDE EXPRESSION IN LIPOPOLYSACCHARIDE-INDUCED MACROPHAGE CELLS

Objective: Nitric oxide (NO) is a signaling molecule that plays a key role in the pathogenesis of inflammation. Inhibitors of NO may be useful candidates for the treatment of inflammatory diseases. The study aimed to determine the antioxidant and inhibitory effect of commonly used Ghanaian vegetables, namely Corchorus olitorius (CO), Solanum melongena (SM), Solanum torvum (ST), Xanthosoma sagittifolia (XS) and Abelmoschus esculentus (AE) on NO expression in a Lipopolysaccharide (LPS)-induced RAW 264.7 macrophage cell line. Methods: The cytotoxic effects of the vegetables on the cell line were determined using a tetrazolium-based colorimetric assay. The inflammatory activity was determined by measuring the inhibition of NO production in LPS-induced RAW 264.7 macrophage cells. Total antioxidant activity, total phenolic, flavonoid, and reduced glutathione contents were evaluated using 2, 2-diphenyl-1-picrylhydrazyl (DPPH) assay, Folin-Ciocalteu, aluminium chloride, and O-Phthalaldehyde methods, respectively. Results: Our results showed that CO and ST significantly inhibited NO production in a concentration-dependent manner with good cell viability. Solanum torvum also exhibited strong antioxidant activity (IC50= 0.466±0.23 mg/ml) with total phenolic content of 230.73±1.84 mg/g GAE, while CO showed high flavonoid content (291.45±2.14 mg/g QUE). Abelmoschus esculentus recorded the highest glutathione content (58.6 µg/g GSH. Saponins, alkaloids, tannins, terpenoids, and cardiac glycosides were present in all the samples except SM and AE, which lacked terpenoids. Conclusion: These findings suggest that CO and ST possess anti-inflammatory and antioxidant activities that could be explored as potential therapeutic remedies for inflammatory disorders.
