ABSTRACT

Seguindo a mesma dinâmica da homeopatia clássica, essa obra sistematiza uma proposta para empregar os fármacos modernos segundo o princípio da similitude terapêutica, estimulando o efeito rebote (reação vital) curativo do organismo através da administração de substâncias (em doses dinamizadas) que despertaram sintomas semelhantes no estado de saúde humano. Vale ressaltar que os efeitos patogenéticos (ações primárias) dos medicamentos homeopáticos clássicos correspondem aos efeitos terapêuticos, adversos e colaterais dos fármacos modernos, os quais devem apresentar uma totalidade sintomática semelhante ao do paciente para estimular a reação vital curativa (efeito rebote curativo), de acordo ao princípio da similitude terapêutica. Para viabilizar essa proposta, foi necessário elaborar uma Matéria Médica Homeopática dos Fármacos Modernos, agrupando os efeitos terapêuticos, adversos e colaterais das drogas conforme a disposição anátomo-funcional dos capítulos das matérias médicas homeopáticas tradicionais, valorizando a frequência de manifestação dos sintomas observadas nas fases de estudo da droga. Como segundo passo, para facilitar a seleção do medicamento individualizado (semelhança com a totalidade de sintomas do paciente) e a aplicação clínica da proposta, foi elaborado um Repertório Homeopático dos Fármacos Modernos, dispondo os sintomas e seus respectivos medicamentos de forma análoga aos repertórios homeopáticos tradicionais, descrito em outra obra desta coleção. (AU)


Following the pattern of traditional homeopathy, this work proposes to employ modern drugs according to the principle of therapeutic similitude, stimulating the healing rebound effect (vital reaction) of the organism through the administration of substances (in infinitesimal doses) that caused similar symptoms in healthy human. Is worth emphasizing that the pathogenetic effects (primary actions) of classical homeopathic medicines correspond to the therapeutic, adverse and side effects of conventional drugs, which should be similar to totality of the symptoms of the patient to stimulate the curative vital reaction (curative rebound effect) according to the principle of therapeutic similitude. To make this proposal operative, a Homeopathic Materia Medica of Modern Drugs was elaborated, where the therapeutic, adverse and side effects of drugs were grouped following the structure of the traditional homeopathic materia medica, while giving particular value to the frequency of the symptoms observed during the phases of study of the drugs. In order to facilitate the selection of the individualized remedy (i.e., similar to the totality of symptoms of the patient), and thus the clinical application of the present proposal, at a later stage it was also elaborated a Homeopathic Repertory of Modern Drugs, where symptoms and remedies are arranged as in the traditional homeopathic repertories, described in another work of this collection.

ABSTRACT

The accessory ß1 subunits, regulating the pharmacological and biophysical properties of BK channels, always undergo post-translational modifications, especially glycosylation. To date, it remains elusive whether the glycosylation contributes to the regulation of BK channels by ß1 subunits. Methods: Herein, we combined the electrophysiological approach with molecular mutations and biochemical manipulation to investigate the function roles of N-glycosylation in ß1 subunits. Results: The results show that deglycosylation of ß1 subunits through double-site mutations (ß1 N80A/N142A or ß1 N80Q/N142Q) could significantly increase the inhibitory potency of iberiotoxin, a specific BK channel blocker. The deglycosylated channels also have a different sensitivity to martentoxin, another BK channel modulator with some remarkable effects as reported before. On the contrary to enhancing effects of martentoxin on glycosylated BK channels under the presence of cytoplasmic Ca2+, deglycosylated channels were not affected by the toxin. However, the deglycosylated channels were surprisingly inhibited by martentoxin under the absence of cytoplasmic Ca2+, while the glycosylated channels were not inhibited under this same condition. In addition, wild type BK (α+ß1) channels treated with PNGase F also showed the same trend of pharmacological results to the mutants. Similar to this modulation of glycosylation on BK channel pharmacology, the deglycosylated forms of the channels were activated at a faster speed than the glycosylated ones. However, the V1/2 and slope were not changed by the glycosylation. Conclusion: The present study reveals that glycosylation is an indispensable determinant of the modulation of ß1-subunit on BK channel pharmacology and its activation. The loss of glycosylation of ß1 subunits could lead to the dysfunction of BK channel, resulting in a pathological state.(AU)

ABSTRACT

Abstract Introduction: improper use of medication is becoming more frequent and can cause physical or physiological damage. Objective: to determine the frequency of potentially inappropriate prescriptions of cardiovascular drugs according to Beers' criteria in a population of colombian patients. Method: cross-sectional study conducted during november 2016 using a population database of 326,192 adults over 65 years of age who were eligible to receive drugs included in the cardiovascular system category according to the Beers' criteria. The frequency of potentially inappropriate prescriptions was determined and investigated in relation to sociodemographic variables. Results: the mean subject age was 74.6±7.6 years (range:65-100 years). It was found that 11.3% (n=36894) of the elderly presented at least one potentially inappropriate prescription for cardiovascular conditions. The most frequent finding was the use of aspirin in patients older than 80 years of age followed by the use of prazosin for hypertension in patients over 65 years of age or in patients who consulted emergency services for syncope. The other criteria were present in less than 1% of patients, and in 16 out of 33 treatment drugs, no patients exposed to potentially inappropriate prescriptions were found. Within the criteria based on drug-drug interactions, the most frequent were loop diuretics along with prazosin (6.4%). Conclusions: the prevalence of potentially inappropriate prescriptions in an elderly population of patients in Colombia is lower than that reported worldwide. In addition, there is a need to re-evaluate the Beers' criteria in this population and adjust the guidelines according to results of pharmacovigilance of active pharmaceutical substances available in Colombia.


Resumen Introducción: el uso incorrecto de medicamentos es cada vez más frecuente y puede causar daños físicos o fisiológicos. Objetivo: determinar la frecuencia de las prescripciones de medicamentos de uso cardiovascular potencialmente inapropiadas según criterios de Beers en una población de pacientes colombianos. Métodos: estudio de corte transversal, a partir de una base de datos de una población de 326.192 adultos mayores de 65 años, durante el mes de noviembre de 2016, susceptibles de recibir medicamentos incluidos en los criterios de Beers en la categoría de sistema cardiovascular, determinando la frecuencia de prescripciones potencialmente inapropiadas, así como la identificación de variables sociodemográficas. Resultados: la edad promedio fue de 74,6±7,6 años (rango 65-100 años). Se halló que el 11,3% (n=36894) de los ancianos tuvo al menos una prescripción potencialmente inapropiada para condiciones cardiovasculares. El criterio más frecuente fue el uso de aspirina en mayores de 80 años, seguido del empleo de prazosín para la hipertensión arterial en mayores de 65 años, o en pacientes que consultaron por síncope a los servicios de urgencias. Los demás criterios se presentaban en menos del 1% de pacientes y en 16 de 33 fármacos de cuidado no se halló ningún paciente expuesto. Entre los criterios basados en interacciones fármaco-fármaco, el más frecuente fue diuréticos de asa junto con prazosín (6,4%). Conclusiones: la prevalencia de prescripciones potencialmente inapropiadas en una población de ancianos colombianos es menor a la reportada en el mundo. Además, se plantea la necesidad de reevaluar los criterios de Beers en dicha población y ajustarlos de acuerdo con los informes de farmacovigilancia y principios activos disponibles en Colombia.

ABSTRACT

The interventional cardiology is growing and evolving. Many complex procedures are now performed outside the operating room to manage cardiovascular pathologies which had been traditionally treated with cardiac surgery. Appropriate sedation strategy is crucial for improved patient comfort and successful procedure while ensuring safety. Sedation for cardiovascular intervention is frequently challenging, especially in critically-ill, high-risk patients. This review addresses pre-procedure evaluation and preparation of patients, proper monitoring, commonly used sedatives and analgesics, and considerations for specific procedures. Appropriate depth of sedation and analgesia should be balanced with patient, procedural and institutional factors. Understanding of the pharmacology of sedatives/analgesics, vigilant monitoring, ability and proper preparation for management of potential complications may improve outcomes in patients undergoing sedation for cardiovascular procedures.

ABSTRACT

OBJECTIVE@#To select potential molecules that can target viral spike proteins, which may potentially interrupt the interaction between the human angiotension-converting enzyme 2 (ACE2) receptor and viral spike protein by virtual screening.@*METHODS@#The three-dimensional (3D)-coordinate file of the receptor-binding domain (RBD)-ACE2 complex for searching a suitable docking pocket was firstly downloaded and prepared. Secondly, approximately 15,000 molecular candidates were prepared, including US Food and Drug Administration (FDA)-approved drugs from DrugBank and natural compounds from Traditional Chinese Medicine Systems Pharmacology (TCMSP), for the docking process. Then, virtual screening was performed and the binding energy in Autodock Vina was calculated. Finally, the top 20 molecules with high binding energy and their Chinese medicine (CM) herb sources were listed in this paper.@*RESULTS@#It was found that digitoxin, a cardiac glycoside in DrugBank and bisindigotin in TCMSP had the highest docking scores. Interestingly, two of the CM herbs containing the natural compounds that had relatively high binding scores, Forsythiae fructus and Isatidis radix, are components of Lianhua Qingwen (), a CM formula reportedly exerting activity against severe acute respiratory syndrome (SARS)-Cov-2. Moreover, raltegravir, an HIV integrase inhibitor, was found to have a relatively high binding score.@*CONCLUSIONS@#A class of compounds, which are from FDA-approved drugs and CM natural compounds, that had high binding energy with RBD of the viral spike protein. Our work provides potential candidates for other researchers to identify inhibitors to prevent SARS-CoV-2 infection, and highlights the importance of CM and integrative application of CM and Western medicine on treating COVID-19.

ABSTRACT

Lycopene is an antioxidant which has potential anti-diabetic activity, but the cellular mechanisms have not been clarified. In this study, different concentrations of lycopene were used to treat pancreatic alpha and beta cell lines, and the changes of cell growth, cell apoptosis, cell cycle, reactive oxygen species (ROS), ATP levels and expression of related cytokines were determined. The results exhibited that lycopene did not affect cell growth, cell apoptosis, cell cycle, ROS and ATP levels of alpha cells, while it promoted the growth of beta cells, increased the ratio of S phase, reduced the ROS levels and increased the ATP levels of beta cells. At the same time, lycopene treatment elevated the mRNA expression levels of tnfα, tgfβ and hif1α in beta cells. These findings suggest that lycopene plays cell-specific role and activates pancreatic beta cells, supporting its application in diabetes therapy.

ABSTRACT

The aim of this study was to investigate the effect of edaravone (Eda) on the balance of mitochondrial fusion and fission in Parkinson's disease (PD) cell model. A cell model of PD was established by treating PC12 cells with 500 μmol/L 1-methyl-4-phenylpyridinium (MPP). Thiazole blue colorimetry (MTT) was used to detect the effect of different concentrations of Eda on the survival rate of PC12 cells exposed to MPP. The mitochondrial morphology was determined by laser confocal microscope. Western blot was used to measure the protein expression levels of mitochondrial fusion- and fission-related proteins, including OPA1, MFN2, DRP1 and Fis1. The results showed that pretreatment with different concentrations of Eda antagonized MPP-induced PC12 cell damage in a dose-dependent manner. The PC12 cells treated with MPP showed mitochondrial fragmentation, up-regulated DRP1 and Fis1 protein expression levels, and down-regulated MFN2 and OPA1 protein expression levels. Eda could reverse the above changes in the MPP-treated PC12 cells, but did not affect Fis1 protein expression. These results suggest that Eda has a protective effect on the mitochondrial fusion disruption induced by MPP in PC12 cells. The mechanism may be related to the up-regulation of OPA1/MFN2 and down-regulation of DRP1.

ABSTRACT

The current study was aimed to investigate the potential effects of perinatal exposure to therapeutic dose of penicillin and cefixime on the cognitive behaviors, gastrointestinal (GI) motility and serum 5-hydroxytryptamine (5-HT) level in the offspring. Pregnant rats were continuously treated with cefixime or penicillin in the period between 1 week before and 1 week after labor. Behavior tests, including social preference, self-grooming and elevated plus maze tests, and intestinal motility tests were carried out on the offspring at age of 4 to 10 weeks. Serum 5-HT levels were detected with ELISA, and potassium/sodium hyperpolarization activated cyclic nucleotide-gated channel 2 (HCN2) and tryptophan hydroxylase 1 (TPH1) expression levels in colon epithelium of offspring were detected by Western blot and RT-qPCR. The results showed that, compared with the naive group, cefixime increased social behavior in the female offspring, but did not affect the male offspring. Compared with the naive group, cefixime significantly decreased colonic and intestinal transits, and increased cecum net weight and standardized cecum net weight in the male offspring, but did not affect the female offspring. The serum 5-HT levels in the male offspring, rather than the female offspring, in cefixime and penicillin groups were significantly increased compared with that in the naive group. The protein expression level of HCN2 in colon epithelium of the offspring in cefixime group was significantly down-regulated, and the TPH1 expression level was not significantly changed, compared with that in the naive group. These results suggest that perinatal antibiotics exposure may affect neural development and GI functions of the offspring, and the mechanism may involve peripheral 5-HT and gender-dependent factor.

ABSTRACT

The purpose of the present study is to investigate the effect of L-cysteine on colonic motility and the underlying mechanism. Immunohistochemical staining and Western blot were used to detect the localization of the HS-generating enzymes cystathionine-β-synthase (CBS) and cystathionine-γ-lyase (CSE). Organ bath system was used to observe the muscle contractile activities. Whole-cell patch-clamp technique was applied to record ionic channels currents in colonic smooth muscle cells. The results showed that both CBS and CSE were localized in mucosa, longitudinal and circular muscle and enteric neurons. L-cysteine had a dual effect on colonic contraction, and the excitatory effect was blocked by pretreatment with CBS inhibitor aminooxyacetate acid (AOAA) and CSE inhibitor propargylglycine (PAG); L-cysteine concentration-dependently inhibited L-type calcium channel current (I) without changing the characteristic of L-type calcium channel (P < 0.01); In contrast, the exogenous HS donor NaHS increased I at concentration of 100 μmol/L, but inhibited I and modified the channel characteristics at concentration of 300 μmol/L (P < 0.05); Furthermore, L-cysteine had no effect on large conductance calcium channel current (I), but NaHS significantly inhibited I (P < 0.05). These results suggest that L-cysteine has a potential dual effect on colonic smooth muscle and the inhibitory effect might be directly mediated by L-type calcium channel while the excitatory effect might be mediated by endogenous HS.

ABSTRACT

Emerging and re-emerging RNA viruses occasionally cause epidemics and pandemics worldwide, such as the on-going outbreak of the novel coronavirus SARS-CoV-2. Herein, we identified two potent inhibitors of human DHODH, S312 and S416, with favorable drug-likeness and pharmacokinetic profiles, which all showed broad-spectrum antiviral effects against various RNA viruses, including influenza A virus, Zika virus, Ebola virus, and particularly against SARS-CoV-2. Notably, S416 is reported to be the most potent inhibitor so far with an EC of 17 nmol/L and an SI value of 10,505.88 in infected cells. Our results are the first to validate that DHODH is an attractive host target through high antiviral efficacy in vivo and low virus replication in DHODH knock-out cells. This work demonstrates that both S312/S416 and old drugs (Leflunomide/Teriflunomide) with dual actions of antiviral and immuno-regulation may have clinical potentials to cure SARS-CoV-2 or other RNA viruses circulating worldwide, no matter such viruses are mutated or not.
