Abstract Species of the genus Echinococcus (Cestoda; Taeniidae) are minute tapeworms of carnivores. Their larvae are known as hydatids (metacestode), which proliferate asexually in various mammals. Like the majority of cestodes, Echinococcus spp. require two different host species to complete their life cycle. Definitive hosts harbouring the adult cestodes in the small intestine are exclusively carnivores of the Canidae and Felidae families. A wide range of mammal species including humans is susceptible to infection by the metacestode of Echinococcus spp., which develops in their viscera. The disease, caused by species of the genus Echinococcus, is called echinococcosis, and it is one of the most dangerous zoonoses in the world. The traditional species Echinococcus granulosus and Echinococcus multilocularis are agents of significant diseases due to the high number of cases and the wide geographical species range. The taxonomy of the genus is controversial; in the current state of ongoing complex revisions, the agent of cystic echinococcosis E. granulosus sensu lato is divided into five species (E. granulosus sensu stricto, E. felidis, E. equinus, E. ortleppi, E. canadensis), in addition to the agents of alveolar echinococcosis (E. multilocularis, E. shiquicus) and polycystic/unicystic echinococcosis (E. vogeli, E. oligarthrus). Here we provide an overview of the current situation, which continues to develop.

While ambitious carbon reduction policies are needed to avoid dangerous levels of climate change, the costs of these policies can be balanced by wide ranging health benefits for local communities. Cities, responsible for ~70% of the world's greenhouse gas (GHG) emissions and home to a growing majority of the world's population, offer enormous opportunities for both climate action and health improvement. We aim to review the current state of knowledge on key pathways leading from carbon mitigation to human health benefits, and to evaluate our current ability to quantify health benefits for cities around the world. For example, because GHGs and air pollutants are both released during fuel combustion, reducing fuel burning can reduce both GHGs and air pollutants, leading to direct health benefits. Air quality improvements may be particularly important for city-scale climate action planning because the benefits occur locally and relatively immediately, compared with the global and long-term (typically, decades to centuries) benefits for the climate system. In addition to improved air quality, actions that promote active transport in cities via improved cycling and pedestrian infrastructure can reap large cardiovascular health benefits via increased physical activity. Exposure to green space has been associated with beneficial health outcomes in a growing number of epidemiological studies and meta-analyses conducted around the world. Finally, noise is an underappreciated environmental risk factor in cities which can be addressed through actions to reduce motor vehicle traffic and other noise sources. All of these environmental health pathways are supported by well-conducted epidemiological studies in multiple locales, providing quantitative exposure–response data that can be used as inputs to health impact assessments (HIAs). However, most epidemiologic evidence derives from studies in high-income countries. It is unclear to what extent such evidence is directly transferable for policies in low- and middle-income countries (LMICs). This gap calls for a future focus on building the evidence based in LMIC cities. Finally, the literature suggests that policies are likely to be most effective when they are developed by multidisciplinary teams that include policy makers, researchers, and representatives from affected communities.

AbstractCancer is a global disease involving transformation of normal cells into tumor types via numerous mechanisms, with mortality among all generations, in spite of the breakthroughs in chemotherapy, radiotherapy and/or surgery for cancer treatment. Since one in six deaths is due to cancer, it is one of the overriding priorities of world health. Recently, bioactive natural compounds have been widely recognized due to their therapeutic effects for treatment of various chronic disorders, notably cancer. Thymoquinone (TQ), the most valuable constituent of black cumin seeds, has shown anti-cancer characteristics in a wide range of animal models. The revolutionary findings have revealed TQ’s ability to regulate microRNA (miRNA) expression, offering a promising approach for cancer therapy. MiRNAs are small noncoding RNAs that modulate gene expression by means of variation in features of mRNA. MiRNAs manage several biological processes including gene expression and cellular signaling pathways. Accordingly, miRNAs can be considered as hallmarks for cancer diagnosis, prognosis and therapy. The purpose of this study was to review the various molecular mechanisms by which TQ exerts its potential as an anti-cancer agent through modulating miRNAs.

SARS-CoV-2 is a new representative of the world of virology related to coronaviruses and can cause a wide range of diseases of the respiratory system: from colds to acute respiratory distress-syndrome with severe respiratory failure. The pathogenesis of a new coronavirus infection (COVID-19) is associated with the ability of SARS-CoV-2 to bind to ACE receptors and subsequently activate IL-6, the main stimulator of the “cytokine storm”. Due to such features of the viral pathogenesis, early and accurate detection of active forms, as well as virus carriage are needed. In review, the whole spectrum of the main diagnostic methods is represented, with a comparison of the effectiveness and con- ditional indication of COVID-19: from the currently used methods (RT-PCR, ELISA) to potentially possible (OT-LAMP, CRISPR), as well as those still under development (chemiluminescence).

Melissa officinalis (M. officinalis) is an herbal-based plant from the family of Lamiaceae and native to Europe and the Mediterranean region, widely used to cure various cancers. Phytochemical investigations proved different compounds such as polyphenolic compounds, flavonoids, and essential oil in the stem and leaves of M. officinalis as main ingredients contributing to different antitumor activity, including antiproliferation and antioxidant antiangiogenetic, antimigratory, antiapoptotic, and change in cell cycle profile of cancer cells. Herbal formulations with colorful ingredients use several types of these mentioned biological processes to display synergistic cancer treatment activities. M. officinalis extracts a wide range from water to ethanol using varied mechanisms to reduce the viability of cancer cells. Hence, scientists are currently interested in evaluating these extracts based on the medical plant to minimize the adverse effects of conventional anti-cancer drugs and discover these mechanisms to pave the way for future studies. This review aimed to discuss the recent studies that M. officinalis have used as an anti-cancer agent to investigate its potential effect on several types of cancer. Therefore, after a short introduction of M. officinalis, we will explain the several biological processes by which M. officinalis exert an anti-cancer effect.
