In addition to various biological effects of natriuretic peptides (NP) on cardiovascular systems, we recently reported that NP raises intracellular temperature in cultured adipocytes. We herein examined the possible thermogenic action of NP in consideration of hemodynamic parameters and inflammatory reaction by proposing structural equation models.
 
  The study population consisted of 1985 consecutive patients who underwent cardiac catheterization. Covariance structure analyses were performed to clarify the direct contribution of plasma B-type NP (BNP) to body temperature (BT) by excluding other confounding factors. A hierarchical path model showed increase in BNP, increase in C-reactive protein and decrease in left ventricular ejection fraction were mutually associated. As expected, C-reactive protein was positively correlated with BT. Importantly, despite a negative correlation between BNP and left ventricular ejection fraction, a decrease in the left ventricular ejection fraction was associated with BT decrease, whereas elevation in BNP level was associated with BT increase independently of C-reactive protein level (P = .007).
 
  Patients with LV dysfunction tend to manifest a decrease in BT, whereas BNP elevation is associated with an increase in BT independently of inflammatory response.  https://www.selleckchem.com/products/OSI-906.html  These findings suggest the adaptive heat-retaining property of NP (and/or NP-associated factors) when BT falls owing to unfavorable hemodynamic conditions in a state of impaired cardiac function.

  The vitamin D endocrine system may have a variety of actions on cells and tissues involved in COVID-19 progression especially by decreasing the Acute Respiratory Distress Syndrome. Calcifediol can rapidly increase serum 25OHD concentration. We therefore evaluated the effect of calcifediol treatment, on Intensive Care Unit Admission and Mortality rate among Spanish patients hospitalized for COVID-19.
 
  Parallel pilot randomized open label, double-masked clinical trial.
 
  University hospital setting (Reina Sofia University Hospital, Córdoba Spain.) PARTICIPANTS 76 consecutive patients hospitalized with COVID-19 infection, clinical picture of acute respiratory infection, confirmed by a radiographic pattern of viral pneumonia and by a positive SARS-CoV-2 PCR with CURB65 severity scale (recommending hospital admission in case of total score > 1).
 
  All hospitalized patients received as best available therapy the same standard care, (per hospital protocol), of a combination of hydroxychloroquine (400 mg every disease, but larger trials with groups properly matched will be required to show a definitive answer.Cordia verbenacea DC is a plant whose geographical distribution is all over Brazil, but mainly on the country's coastal areas. It is used by folk medicine to treat inflammations and chronic pain with application of the raw extract of macerated leaves in the region of pain. This paper aims to provide an integrative review of the role of chemical compounds present in the extract and the essential oil of Cordia verbenacea DC for their anti-inflammatory, antimicrobial and healing properties. The extract of Cordia verbenacea DC is widely found within popular culture as teas, decoctions, infusions, pomades/creams for anti-inflammatory, antimicrobial and healing uses. Its extract is mainly composed of α-humulene, α-pinene, trans-caryophyllene, artemetin, spathulenol and allo-aromadrendene. The described effects of the chemical compounds found in the extract are applied to muscle bruising and myofascial pain, edema reduction and chronic tendonitis, when used topically (with a comercial product being marketed); and tonservation, safe management of the species, use of the extract/essential oil and development of plant-based products.
  The genus Melastoma consists of approximately 100 species distributed widely in tropical and subtropical countries, and Melastoma species are often used for medicinal purposes, such as treatment for bleeding, diarrhea, diabetes, and gynecological tumors by local people, mostly in Southeast Asian countries.
 
  The present review summarizes the traditional uses, phytochemistry and pharmacology of species belonging to Melastoma to suggest further research strategies and to facilitate the exploitation of the therapeutic potential of Melastoma species for the treatment of human disorders.
 
  Information related to the traditional uses, phytochemistry and pharmacological activities was systematically collected by searching for the word "Melastoma" in electronic databases, including SciFinder, Web of Science, PubMed, and Google Scholar, from Apr. 1968 until Dec. 2019.
 
  A systematic literature survey revealed that Melastoma spp. are widely distributed in southern Asia to northern Oceania and the Pacific Islands and re rich in flavonoids, tannins and organic acids with valuable medicinal properties. However, additional studies of the chemical constituents and the mechanism-based pharmacological activities of many members of Melastoma are still needed for developing new plant-derived drugs. In addition, studies on the clinical safety and efficacy of Melastoma are also needed.
  The genus Hosta (Liliaceae family) represents an interesting source of natural bio-constituents, and the 50 species of this genus are widespread in the world. Five species have been used as traditional East Asian medicines for treating inflammation and pain-related diseases. However, the available data for this genus have not been comprehensively reviewed regarding their extracts and secondary metabolites.
 
  The present review aims to provide a deeper insight, better awareness and detailed knowledge of traditional uses, phytochemistry, pharmacology along with toxicological aspects of the genus Hosta in the past decades (February 1964 to August 2020). In addition, the relevance among traditional uses, pharmacology and phytochemistry in folk medicines were extensively discussed.
 
  The relevant information of Hosta species was obtained from several databases. Moreover, the medical books, PhD and MSc dissertations in Chinese were also used to perform this work.
 
  Comprehensive analysis of the afore-mentioned databases, medical books and dissertations confirmed that ethnomedical uses of Hosta genus plants had been recorded in China, Japan, Korea and other countries.
