Review
INTRODUCTION
Menstrual bleeding cessation is one of the most frequent gynecologic disorders among women in reproductive age. The treatment is based on hormone therapy. Due to the increasing request for alternative medicine remedies in the field of women's diseases, in present study, it was tried to overview medicinal plants used to treat oligomenorrhea and amenorrhea according to the pharmaceutical textbooks of traditional Persian medicine (TPM) and review the evidence in the conventional medicine.
METHODS
This systematic review was designed and performed in 2017 in order to gather information regarding herbal medications of oligomenorrhea and amenorrhea in TPM and conventional medicine. This study had several steps as searching Iranian traditional medicine literature and extracting the emmenagogue plants, classifying the plants, searching the electronic databases, and finding evidences. To search traditional Persian medicine references, Noor digital library was used, which includes several ancient traditional medical references. The classification of plants was done based on the repetition and potency of the plants in the ancient literatures. The required data was gathered using databases such as PubMed, Scopus, Google Scholar, Cochrane Library, Science Direct, and web of knowledge.
RESULTS
In present study of all 198 emmenagogue medicinal plants found in TPM, 87 cases were specified to be more effective in treating oligomenorrhea and amenorrhea. In second part of present study, where a search of conventional medicine was performed, 12 studies were found, which had 8 plants investigated: and . Traditional Persian medicine has proposed many different medicinal plants for treatment of oligomenorrhea and amenorrhea. Although just few plants have been proven to be effective for treatment of menstrual irregularities, the results and the classification in present study can be used as an outline for future studies and treatment.

Review
BACKGROUND
The construction of high-voltage direct current (HVDC) lines for the long-distance transport of energy is becoming increasingly popular. This has raised public concern about potential environmental impacts of the static electric fields (EF) produced under and near HVDC power lines. As the second part of a comprehensive literature analysis, the aim of this systematic review was to assess the effects of static EF exposure on biological functions in invertebrates and plants and to provide the basis for an environmental impact assessment of such exposures.
METHODS
The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) was used to guide the methodological conduct and reporting.
RESULTS
Thirty-three studies - 14 invertebrate and 19 plant studies - met the eligibility criteria and were included in this review. The reported behavioral responses of insects and planarians upon exposure strongly suggest that invertebrates are able to perceive the presence of a static EF. Many other studies reported effects on physiological functions that were expressed as, for example, altered metabolic activity or delayed reproductive and developmental stages in invertebrates. In plants, leaf damage, alterations in germination rates, growth and yield, or variations in the concentration of essential elements, for example, have been reported. However, these physiological responses and changes in plant morphology appear to be secondary to surface stimulation by the static EF or caused by concomitant parameters of the electrostatic environment. Furthermore, all of the included studies suffered from methodological flaws, which lowered credibility in the results.
CONCLUSION
At field levels encountered from natural sources or HVDC lines (< 35kV/m), the available data provide reliable evidence that static EF can trigger behavioral responses in invertebrates, but they do not provide evidence for adverse effects of static EF on other biological functions in invertebrates and plants. At far higher field levels (> 35kV/m), adverse effects on physiology and morphology, presumably caused by corona-action, appear to be more likely. Higher quality studies are needed to unravel the role of air ions, ozone, nitric oxide and corona current on alterations in physiological functions and morphology.

Meta-Analysis Review
BACKGROUND
Lavender is considered as one of the medicinal plants to manage stress. Although many preliminary studies evaluated the effect of lavender on individuals' stress level, to the best of our knowledge, we did not find a study that summarizes the results. Therefore, the present study aimed to estimate the Pooled effect of lavender on the stress level of individuals using systematic review and meta-analysis.
METHOD
A systematic literature review based on PRISMA 2020 was performed on the SID, MagIran, Embase, PubMed, Scopus, Web of Science (WoS) databases, and Google Scholar motor engine using related MeSH/Emtree and Free Text words, including "Lavender*", "Lavandula*", "Stress*", "Stress Disorders, Traumatic", and "Stress, Psychological" with no time limitation until August 2021: We also searched two Iranain free local resourses including MagIran https://www.magiran.com and Scientific Information Database (SID) https://www.sid.ir. The quality assessment of studies was performed using JBI checklist. Heterogeneity among studies was quantified using I index and Random Effects model was used to combine the data and perform the meta-analysis.
RESULTS
In the initial search, 1520 articles were found. After excluding the irrelevant studies, finally, 21 articles with a sample size of 791 in the intervention group and 804 in the control group were included in the meta-analysis. As a result of combining the studies, stress score after using lavender in the intervention group showed a significant decrease of 0.63 ± 0.13 (95% CI) more than that in the control group (P < 0.001). The results of subgroup analysis demonstrated that the highest standardized mean difference (SMD) before and after the intervention in the intervention group compared to the control group was related to L. angustifolia species with 0.73 ± 0.22, student groups with 2.27 ± 1.34, and diagnostic tool of Perceived Stress Scale (PSS) with 0.82 ± 0.42, indicating that the difference between the groups was statistically significant (P < 0.001).
CONCLUSION
The pooled estimation of this systematic reiew and meta-analysis revealed that lavender significantly reduces individuals' stress. Therefore, it seems that the use of lavender can be considered as a part of a stress management programs, especially in student groups.

Exposure to Plant Protection Products, PPPs, (fungicides, herbicides and insecticides) is a significant stressor for bees and other pollinators, and has recently been the focus of intensive debate and research. Specifically, exposure through contaminated pollen and nectar is considered pivotal, as it presents the highest risk of PPP exposure across all bee species. However, the actual risk that multiple PPP residues might pose to non-target species is difficult to assess due to the lack of clear evidence of their actual concentrations. To consolidate the existing knowledge of field-realistic residues detected in pollen and nectar directly collected from plants, we performed a systematic literature review of studies over the past 50 years (1968-2018). We found that pollen was the matrix most frequently evaluated and, of the compounds investigated, the majority were detected in pollen samples. Although the overall most studied category of PPPs were the neonicotinoid insecticides, the compounds with the highest median concentrations of residues in pollen were: the broad spectrum carbamate carbofuran (1400 ng/g), the fungicide and nematicide iprodione (524 ng/g), and the organophosphate insecticide dimethoate (500 ng/g). In nectar, the highest median concentration of PPP residues detected were dimethoate (1595 ng/g), chlorothalonil (76 ng/g), and the insecticide phorate (53.5 ng/g). Strong positive correlation was observed between neonicotinoid residues in pollen and nectar of cultivated plant species. The maximum concentrations of several compounds detected in nectar and pollen were estimated to exceed the LD for honey bees, bumble bees and four solitary bee species, by several orders of magnitude. However, there is a paucity of information for the biggest part of the world and there is an urgent need to expand the range of compounds evaluated in PPP studies.

Review
Fungi are morphologically and ecologically diverse kingdom but less explored in the global perspective. This systematic review of mainly higher fungi (mushrooms) and lichenized fungi (lichens) was aimed to convey comprehensive knowledge on these understudied taxa, especially considering diversity, research trends, taxonomic/geographic knowledge gaps, and their contribution to ecosystem services. We investigated literature from the Far Eastern Himalayas and adjacent areas. We followed the PRISM (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) framework for the evidence synthesis and reporting. Search strings were used to explore literature both in English and Chinese databases. Publications were validated examining the title, locality, abstract and full text. We included 75 eligible studies after screening 12,872 publications. The result on species diversity extrapolated from literature was consolidated as a species checklist and published on the Global Biodiversity Information Facility (GBIF) portal. This review demonstrates a significant shortage of research work on fungi, and a lack of quantitative data on diversity, ecology, and ecosystem services. Mycological inventories with multidisciplinary perspectives are urgent in the Landscape to better understand the importance of fungi in conservation and sustainable development science. This review is especially useful when global environmental and climate concerns are focused on the use of nature-based solutions, and fungi as integral part of all ecological processes, could play important role in enhancing ecosystem services and therefore benefits coming to people as natural solutions.

Meta-Analysis Review
BACKGROUND
Vitiligo is a chronic skin disorder characterised by patchy loss of skin colour. Some people experience itching before the appearance of a new patch. It affects people of any age or ethnicity, more than half of whom develop it before the age of 20 years. There are two main types: generalised vitiligo, the common symmetrical form, and segmental, affecting only one side of the body. Around 1% of the world's population has vitiligo, a disease causing white patches on the skin. Several treatments are available. Some can restore pigment but none can cure the disease.
OBJECTIVES
To assess the effects of all therapeutic interventions used in the management of vitiligo.
SEARCH METHODS
We updated our searches of the following databases to October 2013: the Cochrane Skin Group Specialised Register, CENTRAL in The Cochrane Library (2013, Issue 10), MEDLINE, Embase, AMED, PsycINFO, CINAHL and LILACS. We also searched five trials databases, and checked the reference lists of included studies for further references to relevant randomised controlled trials (RCTs).
SELECTION CRITERIA
Randomised controlled trials (RCTs) assessing the effects of treatments for vitiligo.
DATA COLLECTION AND ANALYSIS
At least two review authors independently assessed study eligibility and methodological quality, and extracted data.
MAIN RESULTS
This update of the 2010 review includes 96 studies, 57 from the previous update and 39 new studies, totalling 4512 participants. Most of the studies, covering a wide range of interventions, had fewer than 50 participants. All of the studies assessed repigmentation, however only five reported on all of our three primary outcomes which were quality of life, > 75% repigmentation and adverse effects. Of our secondary outcomes, six studies measured cessation of spread but none assessed long-term permanence of repigmentation resulting from treatment at two years follow-up.Most of the studies assessed combination therapies which generally reported better results. New interventions include seven new surgical interventions.We analysed the data from 25 studies which assessed our primary outcomes. We used the effect measures risk ratio (RR), and odds ratio (OR) with their 95% confidence intervals (CI) and where N is the number of participants in the study.We were only able to analyse one of nine studies assessing quality of life and this showed no statistically significant improvement between the comparators.Nine analyses from eight studies reported >75% repigmentation. In the following studies the repigmentation was better in the combination therapy group: calcipotriol plus PUVA (psoralen with UVA light) versus PUVA (paired OR 4.25, 95% CI 1.43 to 12.64, one study, N = 27); hydrocortisone-17-butyrate plus excimer laser versus excimer laser alone (RR 2.57, 95% CI 1.20 to 5.50, one study, N = 84); oral minipulse of prednisolone (OMP) plus NB-UVB (narrowband UVB) versus OMP alone (RR 7.41, 95% CI 1.03 to 53.26, one study, N = 47); azathioprine with PUVA versus PUVA alone (RR 17.77, 95% CI 1.08 to 291.82, one study, N = 58) and 8-Methoxypsoralen (8-MOP ) plus sunlight versus psoralen (RR 2.50, 95% CI 1.06 to 5.91, one study, N = 168). In these three studies ginkgo biloba was better than placebo (RR 4.40, 95% CI 1.08 to 17.95, one study, N = 47); clobetasol propionate was better than PUVAsol (PUVA with sunlight) (RR 4.70, 95% CI 1.14 to 19.39, one study, N = 45); split skin grafts with PUVAsol was better than minipunch grafts with PUVAsol (RR 1.89, 95% CI 1.25 to 2.85, one study, N = 64).We performed one meta-analysis of three studies, in which we found a non-significant 60% increase in the proportion of participants achieving >75% repigmentation in favour of NB-UVB compared to PUVA (RR 1.60, 95% CI 0.74 to 3.45; I² = 0%).Studies assessing topical preparations, in particular topical corticosteroids, reported most adverse effects. However, in combination studies it was difficult to ascertain which treatment caused these effects. We performed two analyses from a pooled analysis of three studies on adverse effects. Where NB-UVB was compared to PUVA, the NB-UVB group reported less observations of nausea in three studies (RR 0.13, 95% CI 0.02 to 0.69; I² = 0% three studies, N = 156) and erythema in two studies (RR 0.73, 95% CI 0.55 to 0.98; I² = 0%, two studies, N = 106), but not itching in two studies (RR 0.57, 95% CI 0.20 to 1.60; I² = 0%, two studies, N = 106).Very few studies only assessed children or included segmental vitiligo. We found one study of psychological interventions but we could not include the outcomes in our statistical analyses. We found no studies evaluating micropigmentation, depigmentation, or cosmetic camouflage.
AUTHORS' CONCLUSIONS
This review has found some evidence from individual studies to support existing therapies for vitiligo, but the usefulness of the findings is limited by the different designs and outcome measurements and lack of quality of life measures. There is a need for follow-up studies to assess permanence of repigmentation as well as high- quality randomised trials using standardised measures and which also address quality of life.

Review
CONTEXT
Tanzania has rich medicinal plant (MP) resources, and most rural inhabitants rely on traditional healing practices for their primary healthcare needs. However, available research evidence on antimalarial MPs is highly fragmented in the country.
OBJECTIVE
This systematic review compiles ethnomedicinal research evidence on MPs used by Tanzanians as antimalarials.
MATERIALS AND METHODS
A systematic web search was conducted using various electronic databases and grey materials to gather relevant information on antimalarial MPs utilized by Tanzanians. The review was per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. The data were collected from 25 articles, and MS Excel software was used to analyse relevant ethnobotanical information using descriptive statistics.
RESULTS
A total of 227 MPs belonging to 67 botanical families and 180 genera were identified. Fabaceae (15.9%) is the most frequently utilized family. The ethnobotanical recipes analysis indicated leaves (40%) and trees (44%) are the preferred MPs part and life form, respectively. Decoctions (67%) are the dominant preparation method of remedies. Of the recorded MPs, 25.9% have been scientifically investigated for antimalarial activities with positive results. However, 74.1% of MPs have no scientific records on antimalarial activities, but they could be potential sources of remedies.
CONCLUSIONS
The study discloses a wealth of antimalarial MPs possessed by Tanzanians and suggests a need for research to authenticate the healing potential of antimalarial compounds from the unstudied MPs. Additionally, it indicates that some of the presented MPs are potential sources for developing safe, effective and affordable antimalarial drugs.

Review
BACKGROUND
Recent evidence indicates a widening gap in fruit and vegetable (F/V) consumption between high- and low-income Americans. This gap is related, in part, to decreased access to food retailers that sell fresh F/V in low-income communities. Farmers' markets are identified as a strategy for improving F/V consumption by increasing access to these foods.
OBJECTIVES
The aim of this systematic review was to examine literature published from 1994 to 2014 to identify facilitators and barriers of farmers' markets use, particularly among low-income consumers.
DESIGN
Peer-reviewed literature was identified in Ebsco Host (Academic Search Complete). Inclusion criteria for abstract review was primary research focused on farmers' market use identifying 87 studies for full-text review. Full-text review identified articles focused on facilitators and/or barriers of farmers' market use resulting in 49 articles. At least two reviewers completed review of all articles.
RESULTS
Of the 49 articles, 39% specified inclusion of low-income consumers and fewer than 15% focused on racial and ethnic minorities. Few studies were guided by theory and/or used standardized metrics. Results indicate farmers' market use is influenced by multiple economic, service delivery, spatial-temporal, social, and personal factors. Among studies that included low-income populations (n=19), key barriers to farmers' market use were perceptions that food assistance benefits were not accepted, belief that food variety at farmers' markets was limited, lack of access to transportation, lack of racial/ethnic diversity in the market space, and mismatch between markets and personal lifestyles. There is wide variation in study design and reporting standards and infrequent use of standardized measures limiting comparisons across studies.
CONCLUSIONS
There is a need to establish valid and reliable metrics and reporting standards for evaluating farmers' markets. Findings may inform interventions, programs, and policies to promote farmers' market use.

INTRODUCTION
Vitiligo is disfiguring and devastating condition that can humans feel stigmatic and devalued. Melasma is a general condition of hyperpigmentation particularly involving the face. The pigmentation disorders of vitiligo (hypopigmentation or de-pigmentation) and melasma (Hypermelanosis) are common among the world's population (around 1% for vitiligo).
OBJECTIVE
The identification of medicinal plants used in the treatment of vitiligo and hypermelanosis. A systematic literature review on harms associated with the medicinal plants used in the treatment of vitiligo and hypermelanosis. To review and summarize information on reported adverse drug reactions (ADRs) associated with these medicinal plants contained in (where access is available) national and global individual case safety report databases.
METHODS
A systematic review of the literature with special reference to all types of clinical trial and case reports using biomedical databases including Medline, EMBASE, Scopus, International Pharmaceutical Abstracts and so forth to identify medicinal plants alone or as an adjuvant with other treatments and their safety/tolerability in the treatment of vitiligo and Hypermelanosis. Other sources of this search were medicinal plants text books, pharmacopoeias and authentic websites discussing possible treatments for vitiligo/hypermelanosis. It also included databases such as VigiAccess containing data from spontaneous reporting schemes for ADRs.
RESULTS
A total of 55 articles (47 clinical trials and 8 case reports) met the inclusion criteria. Some trials did not reported safety information, some did report, but not very well. Reports of blistering, erythema, acute hepatitis and mutagenesis with . Adverse effects of erythema (mild to severe), phototoxic reactions, mild raise in liver transaminases, gastrointestinal disturbances, burns, itching, scaling, depigmented macules, pruritis, and giddiness with the use of psoralens. Khellin-related erythema, perilesional hyperpigmentation, gastrointestinal disturbances, mild raise in liver transaminases and orthostatic complaints. Infrequent side effects with Ginkgo biloba. Lower grade of erythema and edema reported with the use of
CONCLUSION
Primarily the retrieved clinical studies were efficacy oriented and safety parameters were secondary in priority whilst the general protocol of clinical trials requires the screening of drugs/medicinal plants on the basis of safety studies before testing the clinical aspects of efficacy. Thereby it is recommended that efficacy studies may be followed once the safety has been established for a particular medicinal plant in treating vitiligo and hypermelanosis.

Review
Consumers' dietary patterns have a significant impact on planetary and personal health. To address health and environmental challenges one of the many possible solutions is to substitute meat consumption with alternative protein sources. This systematic review identifies 91 articles with a focus on the drivers of consumer acceptance of five alternative proteins: pulses, algae, insects, plant-based alternative proteins, and cultured meat. This review demonstrates that acceptance of the alternative proteins included here is relatively low (compared to that of meat); acceptance of insects is lowest, followed by acceptance of cultured meat. Pulses and plant-based alternative proteins have the highest acceptance level. In general, the following drivers of acceptance consistently show to be relevant for the acceptance of various alternative proteins: motives of taste and health, familiarity, attitudes, food neophobia, disgust, and social norms. However, there are also differences in relevance between individuals and between alternative proteins. For example, for insects and other novel alternative proteins the drivers of familiarity and affective processes of food neophobia and disgust seem more relevant. As part of gaining full insight in relevant drivers of acceptance, the review also shows an overview of the intervention studies that were included in the 91 articles of the review, providing implications on how consumer acceptance can be increased. The focal areas of the intervention studies included here do not fully correspond with the current knowledge of drivers. To date, intervention studies have mainly focussed on conscious deliberations, whereas familiarity and affective factors have also been shown to be key drivers. The comprehensive overview of the most relevant factors for consumer acceptance of various categories of alternative proteins thus shows large consistencies across bodies of research. Variations can be found in the nuances showing different priorities of drivers for different proteins and different segments, showing the relevance of being context and person specific for future research.
