Abstract
Humans are constantly at high risk of emerging pandemics caused by viral and bacterial infections. The emergence of new pandemics is mainly caused by evolved viruses and bacteria that are highly resistant to existing medications. The rapid evolution of infectious agents demands the urgent investigation of new therapeutic strategies to prevent and treat these infections at an early stage. One of these therapeutic strategies includes the use of medicinal herbs for their antibacterial and antiviral properties. The use of herbal medicines as remedies is very ancient and has been employed for centuries. Many studies have confirmed the antimicrobial activities of herbs against various pathogens in vitro and in vivo. The therapeutic effect of medicinal herbs is mainly attributed to the natural bioactive molecules present in these plants such as alkaloids, flavonoids, and terpenoids. Different mechanisms have been proposed for how medicinal herbs enhance the immune system and combat pathogens. Such mechanisms include the disruption of bacterial cell membranes, suppression of protein synthesis, and limitation of pathogen replication through the inhibition of nucleic acid synthesis. Medicinal herbs have been shown to treat a number of infectious diseases by modulating the immune system's components. For instance, many medicinal herbs alleviate inflammation by reducing pro-inflammatory cytokines (e.g., tumor necrosis factor-alpha (TNF-α), interleukin-1, IL-6) while promoting the production of anti-inflammatory cytokines (e.g., IL-10). Medicinal herbs also play a role in defense against viral and intracellular infections by enhancing the proliferation and functions of natural killer cells, T-helper-1 cells, and macrophages. In this review, we will explore the use of the most common herbs in preventing and treating infectious and non-infectious diseases. Using current and recently published studies, we focus on the immunomodulatory and therapeutic effects induced by medicinal herbs to enhance immune responses during diseases.

Abstract
OBJECTIVE The objective of this sub-analysis of the PERSAT study was to evaluate the efficacy of hexanic extract of S. Repens (HESr) and alpha-blockers (AB), at 6 months in patients with moderate to severe LUTS/BPH. METHODS The PERSAT observational study was conducted in France by general practitioners on patients with BPH with an IPSS≥12 score. The primary endpoint was the percentage of responders (decrease in total IPSS score ≥ 3) at 6 months. Improvement in quality of life (IPSS-QoL) as well as patient satisfaction were also measured. RESULTS Of the 759 patients in the study, 324 treated with HESr and 309 with AB were reviewed at 6 months, with no change in treatment during follow-up. Characteristics at inclusion were globally similar with a mean IPSS of 18.2±4.9. The response rates at 6 months (IPSS-total decrease ≥ 3) were 93.7% and 94.8% for patients treated with HESr and AB, with a mean decrease in IPSS score of 10.1±5.6 points, which reached 13.6 and 14.8 points respectively, in severe patients (IPSS>19), without major difference between groups. More than 95% of HESr or AB patients reported a significant overall improvement in their LUTS/BPH. The most frequently reported adverse events with AB were ejaculation disorders (4.9%) and hypotension (4.2%) and with HESr digestive disorders (1.5%). CONCLUSION This sub-analysis of the PERSAT cohort reported the clinical efficacy of HESr and AB as a first-line treatment in the management of moderate or severe LUTS/BPH patients.

[PMID: 35358858 DOI: 10.1016/j.foodchem.2022.132704] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2021] [Revised: 03/07/2022] [Accepted: 03/12/2022] [Indexed: 11/24/2022]
Abstract
Many species of chili peppers have overlapping morphological characters and delimitation by visual descriptors in many cases fails to differentiate one species from another. In Peru, there are 413 accessions of native chili pepper and 296 accessions of rocotos conserved in the Germplasm Collections of the National Institute of Agrarian Innovation (INIA), of which five accessions (three species from three locations) were selected for the present metabolomic study. The Discrimination of the three species of native chili peppers and identification of biomarkers was performed using untargeted metabolomic approach based on profiling by UHPLC-HRMS and multivariate data analysis. The samples of fresh chili peppers (whole fruit) from Chincha area were used to construct an OPLS-DA model. To validate the biomarkers (identified 15 biomarkers, mainly flavonoids), an external validation set of the OPLS-DA model was constructed using Chiclayo and Huaral collection datasets. Consequently, the OPLS-DA based on Chincha samples model has a high predictive capacity demonstrating that the biomarkers have a high probability of continuity in any culture space, being successful in discriminating the species by untargeted metabolomics.

Comparison of the Phytochemical Variation of Non-Volatile Metabolites within Mother Tinctures of Arnica montana Prepared from Fresh and Dried Whole Plant Using UHPLC-HRMS Fingerprinting and Chemometric Analysis. Molecules 2022; 27:molecules27092737.

Abstract
Arnica montana L. has been recognized for centuries as an herbal remedy to treat wounds and promote healing. It also has a long tradition of use in homeopathy. Depending on its medicinal utilization, standardization regulations allow different manufacturing processes, implying different raw materials, such as the whole arnica plant in its fresh or dried state. In this study, an untargeted metabolomics approach with UHPLC-HRMS/MS was used to cross-compare the phytochemical composition of mother tinctures of A. montana that were prepared from either fresh whole plant (fMT) matter or from oven-dried whole plant (dMT) matter. The multivariate data analysis showed significant differences between fMT and dMT. The dereplication of the HRMS and MS/MS spectra of the more discriminant compounds led to annotated quinic acid, dicaffeoyl quinic acids, ethyl caffeate, thymol derivatives and dehydrophytosphingosine, which were increased in fMT, while Amadori rearrangement products (ARP) and methoxyoxaloyl-dicaffeoyl quinic acid esters were enhanced in dMT. Neither sesquiterpene lactones nor flavonoids were affected by the drying process. This is the first time that a sphingosine, ethyl caffeate and ARP are described in A. montana. Moreover, putative new natural products were detected as 10-hydroxy-8,9-epoxy-thymolisobutyrate and an oxidized proline fructose conjugate, for which isolation and full structure elucidation will be necessary to verify this finding.

Abstract
Phytochemicals are important bioactive components present in natural products. Although the health benefits of many food products are well-known and accepted as a common knowledge, the identity of the main bioactive molecules and the mechanism by which they interact in the body of human are often unknown. It was only in the last 30 years when the field of metabolomics had matured that the identification of such molecules with bioactivity has been made possible through the development of instruments to separate and computational techniques to characterize complex samples. This in turn has enabled in vitro studies to quantify the biological activity of the respective phytochemical either in mice models or in humans. In this review, the importance of key dietary phytochemicals such as phenolic acids, flavonoids, carotenoids, resveratrol, curcumin, and capsaicinoids are discussed together with their potential functions for human health. Untargeted metabolomics, in particular, liquid chromatography mass spectrometry, is the most used method to isolate, identify and profile bioactive compounds in the study of phytochemicals in foods. The application of metabolomics in drug discovery is a common practice nowadays and has boosted the drug and/or supplement manufacturing sector.HighlightsPhytochemicals are beneficial compounds for human healthPhytochemicals are plant-based bioactive and obtainable from natural productsUntargeted metabolomics has boosted the discovery of phytochemicals from foodTargeted metabolomics is key in the authentication and screening of phytochemicalsMetabolomics of phytochemicals is reshaping the road to drug and supplement manufacture.

Abstract
Liposomes represent, among the nanocarriers, the most useful ones for dermatological use, and their composition, charge, size strongly influence their performance in topical drug delivery systems, with possible accumulation of the loaded drugs in the hair follicles. Recently, a saw palmetto carbon dioxide (CO₂) extract has been reported useful for the treatment of hair loss because of the inhibition of 5α-reductase enzyme, responsible of the conversion of testosterone to the most potent androgen, the 5α-dihydrotestosterone. In this work, the formation of nano-sized liposomes and the encapsulation efficiency of saw palmetto CO₂ extract were investigated by light scattering techniques, microscopy and HPLC. The vesicles were loaded with 0.1% w/v saw palmetto CO₂ extract and were small in size (mean size of 145±5 nm). In addition, they were homogeneously dispersed (polydispersity index ≤0.27) and negatively charged (mean value -36.2±3.1 mV). The developed nanoliposomes could represent suitable drug delivery systems to treat the hair loss.

From oil to microparticulate by prilling technique: Production of polynucleate alginate beads loading Serenoa Repens oil as intestinal delivery systems. Int J Pharm 2021; 599:120412.

Abstract
Natural oils that are rich in biologically active polyunsaturated fatty acids have many health benefits but have insufficient bioavailability and may oxidize in the gastrointestinal tract. For these reasons and to improve the handling as well, the possibility of incorporating a natural oil, extracted from Serenoa Repens fruits (SR-oil), in alginate-based beads was investigated. SR-oil has been used from centuries in both traditional and modern medicine for various nutraceutical or therapeutic purposes such as, in both sexes, as a general tonic, for genitourinary problems, to increase sexual vigor, as a diuretic or to treat in male lower urinary tract symptoms and benign prostatic hyperplasia. In this study, alginate-based beads prepared by vibration technology, also known as prilling technique, were explored as SR-oil delivery systems. Twenty-seven different formulations (F1-F27) were produced starting from stable emulsions for the period of the production. The formulations having spheroid shape (sfericity factor <0.07), high formulation yield (>90%) and high encapsulation efficiency (EE% > 80) were selected for further characterizations. Gas chromatographic analysis revealed a high loading of lauric acid as principal component of SR-oil allowing to calculate the content of total fatty acids (>50%) into the beads. Swelling behavior and release features were also studied at different pH values. The swelling of the beads and their SR-oil release were negligible for the first 2 h in simulated gastric fluid (pH 1.2), and appreciable in simulated intestinal fluid (pH 6.8). The release data were fitted by various equations to define the release kinetic mechanism. In addition, the selected formulation (F16) was stable to the oxidation not only during the formulation process, but also after 3 months of storage at room temperature. In summary, these polynucleate alginate beads, produced by prilling technique, are promising systems for improving the intestinal specific delivery and bioavailability of health-promoting bioactive SR-oil.

Mosquito metabolomics reveal that dengue virus replication requires phospholipid reconfiguration via the remodeling cycle. Proc Natl Acad Sci U S A 2020; 117:27627-27636.

Abstract
Dengue virus (DENV) subdues cell membranes for its cellular cycle by reconfiguring phospholipids in humans and mosquitoes. Here, we determined how and why DENV reconfigures phospholipids in the mosquito vector. By inhibiting and activating the de novo phospholipid biosynthesis, we demonstrated the antiviral impact of de novo-produced phospholipids. In line with the virus hijacking lipids for its benefit, metabolomics analyses indicated that DENV actively inhibited the de novo phospholipid pathway and instead triggered phospholipid remodeling. We demonstrated the early induction of remodeling during infection by using isotope tracing in mosquito cells. We then confirmed in mosquitoes the antiviral impact of de novo phospholipids by supplementing infectious blood meals with a de novo phospholipid precursor. Eventually, we determined that phospholipid reconfiguration was required for viral genome replication but not for the other steps of the virus cellular cycle. Overall, we now propose that DENV reconfigures phospholipids through the remodeling cycle to modify the endomembrane and facilitate formation of the replication complex. Furthermore, our study identified de novo phospholipid precursor as a blood determinant of DENV human-to-mosquito transmission.

Abstract
PURPOSE The objective of the PERSAT study was to evaluate first-line treatment of BPH-associated LUTS in real-life conditions. METHODS This prospective observational study was conducted in France by general practitioners (GP) on patients with moderate to severe LUTS (IPSS ≥12). GPs freely decided to prescribe either an alpha-blocker (AB) or phytotherapeutic treatment (PT). The main criterion was the percentage of responding patients (decrease in total IPSS score ≥3) at 6 months. RESULTS Of the 849 patients included, 759 were analysed (381 treated with AB and 378 with PT); 718 were followed up at 6 months, 90% of which had no treatment modification. Their inclusion characteristics were similar between the AB and PT groups (mean IPSS: 18.6±4.5 and 17.8±4.1, respectively). Treatment response rates at 6 months were 94.2% [91.2%; 96.4%] in AB and 92.5% [89.2%; 95.1%] in PT. The IPSS decreased by 10.0±5.6 points, with no difference between groups. The proportion of patients bothered by their LUTS (IPSS-QoL ≥4) evolved from 88.5% to 6.5% at 6 months. The improvement of LUTS was perceived by more than 94% of patients (PGI-I) and doctors (CGI-I), 93% of patients were satisfied with the treatment at 6 months, regardless of the treatment initiated. The most reported adverse reactions were ejaculation disorder (3.9% for AB and 0.9% for PT). CONCLUSION PERSAT confirms in current practice the effectiveness of AB and PT treatments, recommended as first-line treatment in LUTS/BPH. LEVEL OF PROOF 3.

Inflammation is a target of medical treatment for lower urinary tract symptoms associated with benign prostatic hyperplasia. World J Urol 2020; 38:2771-2779. [PMID: 32060633 PMCID: PMC7644532 DOI: 10.1007/s00345-020-03106-1] [Citation(s) in RCA: 21] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2019] [Accepted: 01/23/2020] [Indexed: 12/17/2022] Open
Abstract
Purpose To review the role of a persistent prostatic inflammatory status (PIS) in the development and progression of benign prostatic hyperplasia (BPH) associated with lower urinary tract symptoms (LUTS) and which medical therapies approved for LUTS/BPH may reduce persistent PIS. Methods Literature search in PubMed up to July 2019. Results The cause of histologically defined persistent PIS or chronic prostatic inflammation is multifactorial. It is evident in many men with LUTS/BPH, particularly in older men and in men with a large prostate volume or more severe (storage) LUTS. Additionally, persistent PIS is associated with an increased risk of acute urinary retention and symptom worsening. Of medical therapies approved for LUTS/BPH, the current evidence for a reduction of persistent PIS is greatest for the hexanic extract of Serenoa repens (HESr). This treatment relieves LUTS to the same extent as α1-adrenoceptor antagonists and short-term 5α-reductase inhibitors. Limited evidence is available on the effect of other mainstream LUTS/BPH treatments on persistent PIS. Conclusions Persistent PIS plays a central role in both the development and progression of LUTS/BPH. In men with LUTS/BPH who have a high chance of harbouring persistent PIS, HESr will not only improve LUTS, but also reduce (underlying) inflammation. Well-designed clinical studies, with a good level of evidence, are required to better evaluate the impact of BPH/LUTS medical therapies on persistent PIS.
