Anti-inflammatory activity of diterpene alkaloids from Aconitum baikalense. PUMID/DOI：DOI: 10.1007/s10517-014-2421-4 Bull Exp Biol Med. 2014 Mar;156(5):665-8. We compared anti-inflammatory activity of individual diterpene alkaloids isolated from Aconitum baikalense (napelline, songorine, hypaconitine, mesaconitine, 12-epinapelline N-oxide) under conditions of acute inflammation of different genesis. The tested substances showed high antiexudative activity comparable with that of sodium diclofenac. Unlike nonsteroidal anti-inflammatory drugs, diterpene alkaloids exerted no ulcerogenic effect.

Introduction. Dengue fever is an arboviral disease, which is transmitted by mosquito vector and presents as varied clinical spectrum of dengue fever (DF), dengue hemorrhagic fever (DHF), dengue shock syndrome (DSS), and expanded dengue syndrome (EDS) with atypical presentations, thus posing a diagnostic dilemma. Unless we are aware of these presentations, diagnosis as well as early initiation of treatment becomes difficult. We studied the various clinical presentations of dengue infection during an outbreak of disease in 2015. Materials and Methods. A total of 115 confirmed cases of dengue infection from Department of Medicine of Deen Dayal Upadhyay Hospital, New Delhi, were enrolled in this observational study. Results. The common signs and symptoms of dengue infection were fever, headache, body ache, backache, retro-orbital pain, bleeding manifestations, and rash in 100%, 87%, 86%, 58%, 41%, 21%, and 21%, respectively. Nonspecific or warning signs and symptoms included vomiting, weakness, abdominal pain, breathlessness, vertigo, sweating, and syncope. Other possible signs and symptoms of coinfections, comorbidities, or complications included diarrhea, sore throat, and neurological manifestations. There were seven patients with coinfections and four with comorbidities. The final diagnosis of these patients was DF (73%), DHF (16.5%), DSS (1.7%), and EDS (4.3%). Among EDS patients, the atypical presentations included encephalopathy, lateral rectus nerve palsy, acalculous cholecystitis, and myocarditis. Four patients required ICU care and there was no death in this study. Conclusion. Knowledge of atypical presentations is a must for early diagnosis and timely intervention to prevent life-threatening complications.

In a previous article  we have described the temporal evolution of the Sars-Cov-2 in Italy in the time window February 24-April 1. As we can see in  a generalized logistic equation captures both the peaks of the total infected and the deaths. In this article our goal is to study the missing peak, i.e. the currently infected one (or total currently positive). After the April 7, the large increase in the number of swabs meant that the logistical behavior of the infected curve no longer worked. So we decided to generalize the model, introducing new parameters. Moreover, we adopt a similar approach used in  (for the estimation of deaths) in order to evaluate the recoveries. In this way, introducing a simple conservation law, we define a model with 4 populations: total infected, currently positives, recoveries and deaths. Therefore, we propose an alternative method to a classical SIRD model for the evaluation of the Sars-Cov-2 epidemic. However, the method is general and thus applicable to other diseases. Finally we study the behavior of the ratio infected over swabs for Italy, Germany and USA, and we show as studying this parameter we recover the generalized Logistic model used in  for these three countries. We think that this trend could be useful for a future epidemic of this coronavirus.

A prerequisite for understanding the molecular function of the human cytomegalovirus (HCMV) gH (UL75)-gL (UL115) complex is a detailed knowledge of the structure of this complex in its functional form, as it is present in mature virions. The gH protein is known to be a component of a 240-kDa envelope complex designated as gCIII (D. R. Gretch, B. Kari, L. Rasmussen, R. C. Gehrz, and M. F. Stinski, J. Virol. 62:875-881, 1988). However, the exact composition of the gCIII complex remains unknown. In this report, we attempted reconstitution of the gCIII complex by coexpression of gH and gL in the baculovirus expression system. Formation of recombinant gH-gL complexes of approximately 115 kDa was demonstrated; however, no higher-molecular-mass (approximately 240-kDa) recombinant gH-gL complexes were detected, suggesting that the presence of gH and gL alone is not sufficient for reconstitution of the gCIII complex. To identify other mammalian and/or HCMV factors which may be necessary for gCIII formation, immunoprecipitates of gH and gL from HCMV-infected fibroblasts and purified HCMV virions were examined. This analysis did reveal a number of coprecipitating proteins which associate either transiently or integrally with gH and gL. One coprecipitating protein of 145 kDa was shown to be an integral component of gCIII, along with gH and gL. Characterization of the 145-kDa protein demonstrates that it is structurally and antigenically unrelated to gH and gL and that it appears to be virally encoded. Together, these data indicate that the 145-kDa protein is a third novel component of the mature HCMV gH-gL complex.
