Type 1 Diabetes (T1D) is a complex autoimmune disorder which occurs as a result of an intricate series of pathologic interactions between pancreatic β-cells and a wide range of components of both the innate and the adaptive immune systems. Stem-cell therapy, a recently-emerged potentially therapeutic option for curative treatment of diabetes, is demonstrated to cause significant alternations to both different immune cells such as macrophages, natural killer (NK) cells, dendritic cells, T cells, and B cells and non-cellular elements including serum cytokines and different components of the complement system. Although there exists overwhelming evidence indicating that the documented therapeutic effects of stem cells on patients with T1D is primarily due to their potential for immune regulation rather than pancreatic tissue regeneration, to date, the precise underlying mechanisms remain obscure. On the other hand, immune-mediated rejection of stem cells remains one of the main obstacles to regenerative medicine. Moreover, the consequences of efferocytosis of stem-cells by the recipients’ lung-resident macrophages have recently emerged as a responsible mechanism for some immune-mediated therapeutic effects of stem-cells. Tariquidar cost This review focuses on the nature of the interactions amongst different compartments of the immune systems which are involved in the pathogenesis of T1D and provides explanation as to how stem cell-based interventions can influence immune system and maintain the physiologic equilibrium.Immunocompromised patients, especially those hospitalized, are at higher risk for infection with opportunistic pathogens such as Stenotrophomonas maltophilia (S. maltophilia) which is a multidrug-resistant gram-negative bacillus and can cause a challenge in the management of patients with concomitant COVID-19 and S. maltophilia pneumonia. A 71-year-old man with Hodgkin’s lymphoma presented with severe respiratory symptoms of COVID-19 and was intubated upon admission and the initial standard treatment for COVID-19 was started for him. The patient subsequently developed superimposed bacterial pneumonia with S. maltophilia. According to that, the patient’s intubation tube was removed and a tracheostomy was performed for him. Also, antibiotic treatment was replaced with Colistin and Co-trimoxazole drugs. Finally, after 31 days of hospitalization in the ICU and the aappropriate drug treatment, he was discharged with reduced symptoms and partial recovery. It should be noted that the occurrence of co-infection with multidrug-resistant pathogens such as S. maltophilia requires proper management to select appropriate treatment methods and drugs so that in addition to proper effectiveness, it does not lead to side effects and complications associated with COVID-19 disease.In the beginning of 2020, a newly emerged virus, now named SARS-CoV-2, began to spread in China. After four months, it has reached all over the globe, infecting more than 2.5 million people. Currently, there are no proved treatments available. However, in social media, false information about alcohol consumption and its role against the virus is spreading. We described a victim of these false facts who presented with reduced eyesight due to alcohol drinking, a few days later showed symptoms of COVID-19 and, even though treated, lost his eyesight partially. Alcohol taking has no preventive or curing effect on COVID-19 and negatively impacts the body and immune system, which, therefore, should not be considered a treatment for COVID-19 disease.

Prunella vulgaris, family Lamiaceae also known as self-heal, has been traditionally used as an expectorant, anti-inflammatory, anti-pyretic, and anti-rheumatic. Due to widespread distribution of the plant, Vulgaris is also called ‘vulgar’ in Latin adjective meaning common.

The objective of this review was to describe the relevant aspects of phytochemistry and therapeutic uses of different fractions as well as isolated compounds from Prunella vulgaris. An attempt was also made to enumerate the possible leads e.g. betulinic acid, oleanolic acid, ursolic acid, umbelliferone, scopoletin, esculetin, luteolin, homoorientin, Rosmarinic acid and cinaroside for further development.

For peer-reviewed research literature, we undertook a structured search of bibliographic databases using a focused review question. Scientific databases such as PubMed, Scopus, Science Direct, and Google Scholar were used Results Phytochemistry of Prunella vulgaris (PV) after a thorough literature survey revealed varied and copious meologically active constituents responsible for its activity.Cancer is a global multifactorial disease consisting of over 200 types of cancers. It is well recognized that primary prevention is an effective way to fight cancers by using natural polyphenolic anticancer foods, vegetables and fruits, avoiding exposure to carcinogenic environment, smoking cessation, and through lifestyle modifications. The present review provides up to date information on the effects and functions of pomegranate juice and its bioactive components on the most widespread six cancer types. Pomegranate contains important polyphenolic compounds such as ellagitannins and punicalagin, with strong antioxidant ability for scavenging free radicals and producing metal-chelates in the biological tissues. The in vitro and in vivo studies suggests that antioxidant and anti-inflammation properties of pomegranate constitute have major antimutagenic and antiproliferative activities for regulating gene expression, modulating cellular mechanisms, and limiting the ability of cancers to metastasize. A limited number of clinical studies have suggested that pomegranate ingredients have the potential for the prevention and treatment of cancer, especially colorectal and prostate cancer. In cancer therapy, it remains a clinical dilemma to hit the right target without inducing side effects. The costly anticancer chemotherapies are often associated with drug resistance and serious side effects in vital organs, and noncancerous neighboring cells. It appears that the pomegranate based phytotherapies would be affordable and cost-effective for next generation non-pharmacologic anticancer remedies with lesser side effects. However, well-designed, randomized, double-blind, and multi-center studies are needed to establish the long-term safety, efficacy and dose schedules for orally deliverable pomegranate formulations.
