Toxicity as prime selection criterion among SARS-active herbal medications

2021

We present here a new selection criterion for prioritizing research on efficacious drugs for the fight against COVID-19: the relative toxicity versus safety of herbal medications, which were effective against SARS in the 2002/2003 epidemic. We rank these medicines according to their toxicity versus safety as basis for preferential rapid research on their potential in the treatment of COVID-19. The data demonstrate that from toxicological information nothing speaks against immediate investigation on, followed by rapid implementation of Lonicera japonica, Morus alba, Forsythia suspensa, and Codonopsis spec. for treatment of COVID-19 patients. Glycyrrhiza spec. and Panax ginseng are ranked in …

Estudio de la función de los factores de transcripción PBX en la diferenciación a neurona dopaminérgica del bulbo olfatorio de ratón

2017

[EN] Dopamine signalling regulates a variety of complex behaviours and defects in dopaminergic neuron function or survival result in severe human pathologies such as Parkinson´s disease. All dopaminergic neurons are characterized by the expression of a battery of genes that code for a set of proteins required for the synthesis, release and re-uptake of dopamine and all together are called the DA pathway genes. Therefore, understanding how this set of genes are transcriptionally activated in a coordinated manner is the first step to discover the clues of dopaminergic terminal differentiation. The dopamine pathway genes are highly conserved throughout evolution. Studies in the nematode C.eleg…

The N-terminal domain of the light-harvesting chlorophyll a/b-binding protein complex (LHCII) is essential for its acclimative proteolysis.

2000

AbstractVariations in the amount of the light-harvesting chlorophyll a/b-binding protein complex (LHCII) is essential for regulation of the uptake of light into photosystem II. An endogenous proteolytic system was found to be involved in the degradation of LHCII in response to elevated light intensities and the proteolysis was shown to be under tight regulation [Yang, D.-H. et al. (1998) Plant Physiol. 118, 827–834]. In this study, the substrate specificity and recognition site towards the protease were examined using reconstituted wild-type and mutant recombinant LHCII. The results show that the LHCII apoprotein and the monomeric form of the holoprotein are targeted for proteolysis while t…

Evaluation of Antimicrobial Activity of Triphala Constituents and Nanoformulation

2020

The prevalence of nosocomial infections due to multidrug resistant (MDR) bacterial strains is associated with high morbidity and mortality. Folk medicine and ethnopharmacological data can provide a broad range of plants with promising antimicrobial activity. Triphala, an Ayurvedic formula composed of three different plants: Terminalia chebula Retz., Terminalia bellirica (Gaertn.) Roxb. (Combretaceae), and Phyllanthus emblica L. (Phyllanthaceae), is used widely for various microbial infections. Various extraction techniques were applied in the extraction of the biologically active constituents of Triphala in order to compare their efficiency. Microwave-assisted extraction (MAE) was shown to …

Acute Nonlymphocytic Leukemia in Adults: Pathophysiology, Status of Current Therapy, and New Approaches

1987

Recent information concerning the cell biology of leukemias has provided new insights into the pathophysiology and pathogenesis of acute leukemia, involving the detection of leukemia viruses, oncogenes and their products, and the discovery of factors supporting clonal leukemic growth. Murine, avian, and cat leukemia viruses are well characterized. To date, only HTLV I appears to be a likely candidate as a human leukemia virus. For both avian and murine viruses, there is a fundamental classification distinction between long-latency viruses (LLV) and acute transforming viruses (ATV). The ATV are replication defective and must be propagated with a helper virus. They have within their genome an…

Relationship between apoptosis and survival molecules in human cumulus cells as markers of oocyte competence

2017

SummaryTo select from a single patient the best oocytes able to reach the blastocyst stage, we searched for valuable markers for oocytes competence. We evaluated the DNA fragmentation index (DFI) and the level of some survival molecules, such as AKT, pAKT and pERK1/2, in individual cumulus cell–oocyte complexes (COC). The study included normo-responder women. The average age of the patients was 34.3. DFI in cumulus cells was evaluated using the terminal deoxynucleotidyl transferase (TdT) dUTP nick-end labelling (TUNEL) assayin situ. AKT, pAKT and pERK1/2 were measured by immunological assay and densitometric analysis of fluorescent signals using NIS-Elements BR 3.10 image software. Statisti…

Comparing counseling and dignity therapies in home care patients: A pilot study

2015

AbstractObjective:Several studies have successfully tested psychosocial interventions in palliative care patients. Counseling is the technique most often employed. Dignity therapy (DT) has recently emerged as a tool that can be utilized to address patients' needs at the end of life. The aims of our study were to examine the effects of DT and counseling and to offer useful information that could be put into practice to better meet patients' needs.Method:We developed a pilot randomized controlled trial at the Home Care Unit of the General University Hospital of Valencia (Spain). Some 70 patients were assigned to two therapy groups. The measurement instruments employed included the Patient Dig…

Incidence of lineage promiscuity in acute myeloblastic leukemia: Diagnostic implications of immunoglobulin and T-cell receptor gene rearrangement ana…

1988

Abstract Sixty-nine blood or bone marrow samples from both children and adults with acute myeloblastic leukemia (AML) were investigated to elucidate the frequency of immunoglobulin (IG) and T-cell receptor (TCR)-gene rearrangements. Non-germline configuration for the IG heavy chain (h) gene was detected in the specimens of nine patients of various subtypes according to the French-American-British classification (FAB), including FAB M1, M2, M4 and M5. Rearrangement of the IG kappa chain (k) gene was present in one of these cases which simultaneously revealed a rearranged TCR-beta (b) chain gene. In another two AML samples we found TCR-b gene rearrangements, in one case in combination with an…

Vitamin D supplementation, bone turnover, and inflammation in HIV-infected patients

2018

IF 1.307 (2017); International audience; ObjectiveTo assess whether vitamin D supplementation could be associated with a modification of inflammatory markers and bone turnover in HIV-1-infected patients.Patients and methodsPatients who participated in an initial survey in 2010 and who were followed in the same department were included in a new study in 2012. Between 2010 and 2012, vitamin D supplementation was offered to patients presenting with hypovitaminosis D as per appropriate guidelines. Clinical examinations were performed, and fasting blood samples were taken for inflammation and bone marker evaluations.ResultsOf the 263 patients who participated in the 2010 study, 198 were included…
