Comparison of the antidepressant like activity of homeopathic remedies (Argentum nitricum, Staphysagria and Ignatia amara) and their effect on the behavior of rodents.

The majority of the world population suffers from mental and behavioral disorder. It is the need of the time to find an alternate of presently available medicines in order to decrease the medical expense. Homeopathic remedies are available and prescribed by homeopaths for treatment of anxiety and depression. Unfortunately, no data are available that proves its potential to relieve mental illness. The current study is designed to assess neuro behavioral and antidepressant like effects of homeopathic remedies Staphysagria, Argentum nitricum and Ignatia amara in comparison with standard drug (escitalopram). Different neuro behavioral activities were analyzed. The animals were administered the doses of all homeopathic remedied (60 µl to the rats) and escitalopram (0.042 mg to rats) through the oral route. The activities were observed on day 30th and day 60th. Our result suggests that the swimming time in Staphysagria treated group were significantly improved (p<0.001) after day 60th and significance rise was observed (p<0.01) in Ignatia amara treated animals, whereas significant decline (p<0.05) in struggling time was observed in Argentum nitricum administered animals after the 60th day as compared to 30th day. The central square crossings were improved highly significantly (p<0.001) after the 30th day dosing, by all three remedies and peripheral squares crossing were found highly significantly increased (p<0.001) after chronic dosing in Staphysagria and Ignatia amara treated groups. It is concluded from the results that all three homeopathic remedies produce comparable effects like standard drug while among all three remedies Staphysagria possess a potent antidepressant activity. To the best of our knowledge the current study reports first time the anti-depressant potential of homeopathic remedies in rodents.

Homeopathic treatment as an alternative prophylactic to minimize bacterial infection and prevent neonatal diarrhea in calves.

Bovine neonatal diarrhea is common due low immunity in newborn calves, poor management (or absence) of sanitary barriers, and other factors. Newborn calves with diarrhea in the first days of life suffer failure to thrive and may die if left untreated. The aim of this study was to evaluate whether prophylactic administration of a homeopathic product (Dia 100®) can control bovine neonatal diarrhea in calves born on a farm with substantial sanitary challenges. We counted total bacteria and protozoan parasites in fecal samples. We measured serum glucose, total protein, globulin, albumin, cholesterol and triglycerides on days 1, 7 and 14 of life. Twenty newborn calves were maintained in individual stalls, and were divided in two groups: ten untreated animals (control) and ten animals treated with Dia 100®. Fecal consistency was evaluated daily. We diagnosed diarrhea in five animals in the treated group, and in all animals from the control group. Infections with Escherichia coli and Giardia duodenalis were identified as the responsible organisms. The E. coli count was low in the treatment group on day 7 of life compared with the control group. Antibiotics were given to eight animals in the control group, and to two animals in the treatment group. On day of life 7, serum levels of total protein and globulins were higher in the control group, but were lower on day 14. Serum levels of glucose and triglycerides were greater in treated animals on days 7 and 14, suggesting that the homeopathic product contributes to improvement of intestinal health and absorption and nutrients. We conclude that Dia 100® controls diarrhea with 50% of efficacy, and reduces antibiotic utilization.

Homeopathy in the Age of Antimicrobial Resistance: Is It a Viable Treatment for Upper Respiratory Tract Infections?

BACKGROUND: Acute upper respiratory tract infections (URTIs) and their complications are the most frequent cause of antibiotic prescribing in primary care. With multi-resistant organisms proliferating, appropriate alternative treatments to these conditions are urgently required. Homeopathy presents one solution; however, there are many methods of homeopathic prescribing. This review of the literature considers firstly whether homeopathy offers a viable alternative therapeutic solution for acute URTIs and their complications, and secondly how such homeopathic intervention might take place. METHOD: Critical review of post 1994 clinical studies featuring homeopathic treatment of acute URTIs and their complications. Study design, treatment intervention, cohort group, measurement and outcome were considered. Discussion focused on the extent to which homeopathy is used to treat URTIs, rate of improvement and tolerability of the treatment, complications of URTIs, prophylactic and long-term effects, and the use of combination versus single homeopathic remedies. RESULTS: Multiple peer-reviewed studies were found in which homeopathy had been used to treat URTIs and associated symptoms (cough, pharyngitis, tonsillitis, otitis media, acute sinusitis, etc.). Nine randomised controlled trials (RCTs) and 8 observational/cohort studies were analysed, 7 of which were paediatric studies. Seven RCTs used combination remedies with multiple constituents. Results for homeopathy treatment were positive overall, with faster resolution, reduced use of antibiotics and possible prophylactic and longer-term benefits. CONCLUSIONS: Variations in size, location, cohort and outcome measures make comparisons and generalisations concerning homeopathic clinical trials for URTIs problematic. Nevertheless, study findings suggest at least equivalence between homeopathy and conventional treatment for uncomplicated URTI cases, with fewer adverse events and potentially broader therapeutic outcomes. The use of non-individualised homeopathic compounds tailored for the paediatric population merits further investigation, including through cohort studies. In the light of antimicrobial resistance, homeopathy offers alternative strategies for minor infections and possible prevention of recurring URTIs.

Determinants of patients preferring Complementary and Alternative medicine attending public hospitals in Lahore, Pakistan.

OBJECTIVE: To find the frequency and determinants of patients preferring complementary and alternative medicine over registered medical doctors.. METHODS: This cross-sectional study was conducted at Services Hospital, Mayo Hospital and Jinnah Hospital in Lahore, Pakistan, from June 8 to August 20, 2017.A pre-tested self-administered questionnaire was used to collect data. SPSS 20 was used for data analysis. . RESULTS: Of the 385 subjects, 200(51.9%) had visited at least one complementary and alternative medicine healer in their life. Besides, 166(83%) subjects confirmed positive outcome of such therapies. When asked about reasons behind their choice,227(59%)subjects mentioned cost effectiveness, 99(25.7%) better understanding, 131(34%) guidance about disease by such healers, 198(51.4%) harmless therapies, 198(51.4%) natural ingredients of medicines, 154(40%) accessibility, 161(41.8%) psychological satisfaction, 221(57.4%) said fewer appointments, 222(57.7%) said diagnosis without laboratory tests, 131(34%)family influence, 52(13.5%) had surgical fears, 101(26.2%) said faith in spiritual exercises, 63(16.4%) were addicted to complementary and alternative medicine products, 122(31.7%) said better communication) while183(47.5%) said sparing more time for consultation. CONCLUSIONS: There were a variety of beliefs and reasons behind patients preferring complementary and alternative medicine providers over medical doctors.

Buerger's disease in the northeast of Iran: Epidemiology and clinical features.

BACKGROUND: The aim of this study is to present our long-term clinical experience in describing a clinical picture of Buerger's disease in our region. MATERIALS AND METHODS: In a retrospective study, files of 225 patients who were admitted to the hospital with diagnosis of thromboangiitis obliterans in a 10 year period from 2000 to 2010 were reviewed. All data including demographic, signs and symptoms, history of previous illness, history of smoking, medications, laboratory tests, angiography, and details of surgical operation were obtained. RESULTS: A total of 222 (98.7%) and 3 (1.3%) of patients were male and female, respectively. Average age of hospitalized patients was 40.7 ± 8.5 (20-62) years. A total of 200 patients (88.9%) were active cigarette smokers while 168 (74.7%) of them were opium addicts. The most prevalent symptoms were chronic ulcers (80%) and claudication (63.6%). Minor and major amputation was required in 113 (50.2%) and 41 (18.4%) patients, respectively. Amputation was carried out on the lower limb (80%), upper limb (4.1%), or on both (15.1%). Also, four patients underwent revascularization through surgical bypass procedures. CONCLUSIONS: The diagnosis and treatment of Buerger's Disease is still a challenge in those communities where the disease is endemic. Therefore, identifying the natural course of the disease can play a pivotal role in the diagnosis and treatment of these patients.

Nasal Foreign Bodies: A Sweet Experiment.

INTRODUCTION: It is generally accepted that paediatric intranasal foreign bodies should be removed in the emergency setting. In the case of a difficult to access dissolvable foreign body in an uncooperative child, the question must be raised regarding whether or not a watch and wait strategy is more appropriate. We ask: How long does it take for popular sweets (candy) to dissolve in the human nose? METHODS: Five popular UK sweets were placed in the right nasal cavity of a 29-year-old male (the author) with no sino-nasal disease. Time taken to dissolve was recorded. RESULTS: All five sweets were completely dissolved in under one hour. DISCUSSION: A watch and wait strategy in favour of examination under anaesthetic may be a viable option in some cases. Limitations of the study include the age of the participant and size of the sweets. It is also important in practice that the clinician is able to elicit an accurate history regarding the exact nature of the foreign body. CONCLUSION: It remains prudent to perform an examination under anaesthetic of an uncooperative child with a solid or unknown nasal foreign body. However, if the clinician can be certain the foreign body is a small sugar or chocolate based sweet only, a watch and wait strategy may be a reasonable choice.

Self-awakening improves alertness in the morning and during the day after partial sleep deprivation.

The ability to awaken at a predetermined time without an alarm is known as self-awakening. Self-awakening improves morning alertness by eliminating sleep inertia; however, the effects of self-awakening on daytime alertness and alertness that has deteriorated as a result of sleep loss are unknown. The aim of this study was to determine the effects of self-awakening on both morning and daytime alertness after partial sleep deprivation. Fifteen healthy males without the habit of self-awakening participated in a cross-over trial including forced awakening and self-awakening conditions. In each condition, participants' sleep was restricted to 5 h per night in their homes for 4 consecutive days. They completed a psychomotor vigilance task and subjective ratings of sleepiness immediately upon awakening each morning. On the fourth day, participants completed subjective ratings of sleepiness, a psychomotor vigilance task and sleep latency tests in the laboratory seven times at 1-h intervals during the day. The response speed on the psychomotor vigilance task, in the morning and during the day, was higher in the self-awakening than the forced awakening condition. Our results showed that self-awakening improved alertness (assessed by response speeds) by reducing sleep inertia and alleviated daytime sleepiness heightened by partial sleep deprivation.

Homeopathic medicine for acute cough in upper respiratory tract infections and acute bronchitis: a randomized, double-blind, placebo-controlled trial.

Cough is a frequent symptom associated to upper respiratory tract infections (URTIs) and, although being self-limiting, it might deeply affect the quality of life. Homeopathic products are often employed by patients to treat cough, but the evidence on their efficacy is scarce. Thus, we tested the efficacy of a homeopathic syrup in treating cough arising from URTIs with a randomized, double blind, placebo controlled clinical trial. Patients were treated with either the homeopathic syrup or a placebo for a week, and recorded cough severity in a diary by means of a verbal category-descriptive score for two weeks. Sputum viscosity was assessed with a viscosimeter before and after 4 days of treatment; patients were also asked to provide a subjective evaluation of viscosity. Eighty patients were randomized to receive placebo (n = 40) or the homeopathic syrup (n = 40). All patients completed the study. In each group cough scores decreased over time, however, after 4 and 7 days of treatment, cough severity was significantly lower in the homeopathic group than in the placebo one (p < 0.001 and p = 0.023, respectively). Sputum was collected from 53 patients: in both groups its viscosity significantly decreased after 4 days of treatment (p < 0.001); however, viscosity was significantly lower in the homeopathic group (p = 0.018). Instead, the subjective evaluation did not significantly differ between the two groups (p = 0.059). No adverse events related to any treatment were reported. We concluded that the homeopathic syrup employed in the study was able to effectively reduce cough severity and sputum viscosity, thereby representing a valid remedy for the management of acute cough induced by URTIs.

Self-experimentations with psychedelics among mental health professionals: LSD in the former Czechoslovakia.

This article enquires into auto-experiments with psychedelics. It is focused on the experiences and current attitudes of mental health professionals who experimented with LSD in the era of legal research of this substance in the former Czechoslovakia. The objective of the follow-up study presented was to assess respondents' long-term views on their LSD experience(s). A secondary objective was to capture the attitude of the respondents toward the use of psychedelics within the mental health field. A total of 22 individuals participated in structured interviews. None of the respondents reported any long-term negative effect and all of them except two recorded enrichment in the sphere of self-awareness and/or understanding to those with mental disorder(s). Although there were controversies with regard to the ability of preventing possible negative consequences, respondents were supportive towards self-experiments with LSD in mental health sciences. This article is the first systematic examination of the self-experimentation with psychedelics that took place east of the Iron Curtain.

Long-Term Effects of Opium Consumption Following Percutaneous Coronary Intervention: A 10-year Follow-Up Study.

Background: Opium consumption has been an overlooked health issue in the Iranian population, and the prognostic role of opium consumption in patients undergoing coronary revascularization is unknown. Hypothesis: We aimed to assess the association between opium consumption and long-term cardiovascular outcomes after percutaneous coronary intervention (PCI). Methods: We screened 2203 consecutive patients who underwent elective PCI between April 2009 and April 2010 at Tehran Heart Center. Exclusion criteria were unsuccessful PCI, non-elective PCI, and missing opium use data. Opium consumption was defined as self-reported ever use of any traditional opium substances. Outcomes of interest were all-cause mortality and a composite of major adverse cardiac and cerebrovascular events (MACCE). The association between opium use and study outcomes was evaluated using the inverse probability of treatment weighting (IPTW) method. Cumulative hazard curves were demonstrated to further assess the association visually. Furthermore, the effect of opium consumption on individual components of MACCE was evaluated in a competing risk setting. Results: A total of 2025 elective PCI patients were included (age: 58.7 ± 10.67, 29.1% women), among whom 297 (14.6%) patients were opium users. After a median follow-up of 10.7 years, opium consumption was associated with a higher risk of all-cause mortality (IPTW-hazard ratio [HR] = 1.705, 95% CI: 1.125-2.585; P = 0.012) and MACCE (IPTW-HR = 1.578, 95% CI: 1.156-2.153; P = 0.004). The assessment of MACCE components suggested a non-significant borderline trend for higher non-fatal myocardial infarction (IPTW-sub-distribution HR [SHR] = 1.731, 95% CI: 0.928-3.231; P = 0.084) and mortality (IPTW-SHR = 1.441, 95% CI: 0.884-2.351; P = 0.143) among opium users. Conclusions: Opium consumption is associated with a more than 50% increase in long-term risk of mortality and MACCE in patients undergoing PCI. These findings accentuate the importance of preventive strategies to quit opium addiction in this population.

Poppy APETALA1/FRUITFULL orthologs control flowering time, branching, perianth identity, and fruit development.

Several MADS box gene lineages involved in flower development have undergone duplications that correlate with the diversification of large groups of flowering plants. In the APETALA1 gene lineage, a major duplication coincides with the origin of the core eudicots, resulting in the euFUL and the euAP1 clades. Arabidopsis FRUITFULL (FUL) and APETALA1 (AP1) function redundantly in specifying floral meristem identity but function independently in sepal and petal identity (AP1) and in proper fruit development and determinacy (FUL). Many of these functions are largely conserved in other core eudicot euAP1 and euFUL genes, but notably, the role of APETALA1 as an "A-function" (sepal and petal identity) gene is thought to be Brassicaceae specific. Understanding how functional divergence of the core eudicot duplicates occurred requires a careful examination of the function of preduplication (FUL-like) genes. Using virus-induced gene silencing, we show that FUL-like genes in opium poppy (Papaver somniferum) and California poppy (Eschscholzia californica) function in axillary meristem growth and in floral meristem and sepal identity and that they also play a key role in fruit development. Interestingly, in opium poppy, these genes also control flowering time and petal identity, suggesting that AP1/FUL homologs might have been independently recruited in petal identity. Because the FUL-like gene functional repertoire encompasses all roles previously described for the core eudicot euAP1 and euFUL genes, we postulate subfunctionalization as the functional outcome after the major AP1/FUL gene lineage duplication event.

Comparison of early versus late initiation of GnRH antagonist co-treatment for controlled ovarian stimulation in IVF: a randomized controlled trial.

STUDY QUESTION: What is the impact of initiating GnRH antagonist co-treatment for in vitro fertilization (IVF) on cycle day (CD) 2 compared with CD 6 on live birth rate (LBR) per started cycle and on the cumulative live birth rate (CLBR)? SUMMARY ANSWER: Early initiation of GnRH antagonist does not appear to improve clinical outcomes of IVF compared with midfollicular initiation. WHAT IS KNOWN ALREADY: During ovarian stimulation for IVF, GnRH antagonist co-treatment is usually administered from the midfollicular phase onwards. Earlier initiation may improve the follicular phase hormonal milieu and therefore overall clinical outcomes. STUDY DESIGN, SIZE, DURATION: This open-label, multicentre randomized controlled trial was conducted between September 2009 and July 2011. A web-based program was used for randomization and 617 IVF-intracytoplasmic sperm injection (ICSI) patients were included. PARTICIPANTS/MATERIALS, SETTING, METHODS: Recombinant FSH (150-225 IU) was administered daily from CD 2 onwards in both groups. The study group (CD2; n = 308) started GnRH antagonist co-treatment on CD 2, whereas the control group (CD6; n = 309) started on CD 6. MAIN RESULTS AND THE ROLE OF CHANCE: There were no significant differences in clinical outcomes between the two groups. A non-significant trend towards a higher LBR per started cycle and CLBR was observed in the CD6 group compared with the CD2 group (LBR: 24.0 versus 21.5%, P = 0.5; CLBR: 29.9 versus 26.7%, P = 0.6). LIMITATIONS, REASONS FOR CAUTION: The study was terminated prematurely because no significant difference was observed in clinical outcomes after 617 inclusions. A much larger study population would be needed to detect a small significant difference in favour of either study arm, which raises the question of whether this would be relevant for clinical practice. WIDER IMPLICATIONS OF THE FINDINGS: The present study shows that the additional treatment burden and costs of starting GnRH antagonist on CD 2 instead of on CD 6 are not justified, as early initiation of GnRH antagonist does not improve LBRs.

Pattern and predictors of complementary and alternative medicine (CAM) use among pediatric patients with epilepsy.

Parents of pediatric patients with chronic conditions such as epilepsy increasingly opt for complementary and alternative medicine (CAM). However, data on the pattern and reasons of CAM use in childhood epilepsy are scarce. The objectives of this study were as follows: first, to characterize CAM use among pediatric patients with epilepsy by assessing its spectrum, prevalence, costs, and frequency of use; second, to evaluate the influence of CAM use on compliance and satisfaction with conventional care as well as to explore parent-child neurologist communication concerning CAM; and third, to investigate predictors of CAM use. A postal survey was administered to all parents of pediatric outpatients with epilepsy aged 6 to 12, who have received treatment at the neuropediatric outpatient clinic of the University Children's Hospital Heidelberg between 2007 and 2009. One hundred thirty-two of the 297 distributed questionnaires were suitable for inclusion in statistical analysis (44.7%). Forty-nine participants indicated that their children used CAM during the previous year (37.1%). Thirty different types of CAM were used, with homeopathy (55.1%), osteopathy (24.5%), and kinesiology (16.3%) being the most commonly named. A mean of 86€ (0€-500€) and 3h (1 h-30 h) per month was committed to CAM treatment. Only 53% of the users informed their child neurologist of the additional CAM treatment, while 85.6% of all parents wished to discuss CAM options with their child neurologist. Seventy-five percent of users considered the CAM treatment effective. Among the participants most likely to seek CAM treatment are parents whose children show a long duration of epileptic symptoms, parents who make use of CAM treatment themselves, and parents who value a holistic and natural treatment approach. A substantial portion of pediatric patients with epilepsy receive CAM treatment. The high prevalence of use and significant level of financial and time resources spent on CAM indicate the high importance of these treatment options for parents. On the other hand, communication concerning CAM with the child neurologist is largely insufficient despite the wish to speak about CAM. Complementary and alternative medicine users' high compliance with conventional treatment and high perceived effectiveness of CAM support an integrative approach to CAM for pediatric patients with epilepsy. Our study implies that in addition to open parent-child neurologist communication, active inquiry on CAM treatments is necessary to enable informed decision making by parents and to establish the suitability of CAM treatment for the patient. Reliable predictors for CAM use, which allow for improved identification of patients with a high likelihood to receive CAM treatment, are the duration of the illness, use of CAM by the parents themselves, and the desire of the parents to receive a holistic and natural treatment for their child.

Opium could be considered an independent risk factor for lung cancer: a case-control study.

BACKGROUND: Lung cancer is the leading cause of cancer-related death worldwide, and half of all incident lung cancers are believed to occur in the developing countries, including Iran. OBJECTIVE: We investigated the association of opium with the risk of lung cancer in a case-control study. METHODS: We enrolled 242 cases and 484 matched controls in this study. A questionnaire was developed, containing questions on basic demographic characteristics, as well as lifelong history of smoking cigarettes, exposure to passive smoking, opium use and alcohol consumption. For smoking cigarettes and opium and also oral opium intake frequency, duration and cumulative use were categorized into three groups: no use, low use and high use. Conditional logistic regression was used to calculate the odds ratios (ORs) and 95% confidence intervals (CIs). RESULTS: Multivariate analysis in men showed that after adjusting for the effect of ethnicity, education and pack years of smoking cigarettes, smoking opium remained as a significant independent risk factor with an OR of 3.1 (95% CI 1.2-8.1). In addition, concomitant heavy smoking of cigarettes and opium dramatically increased the risk of lung cancer to an OR of 35.0 (95% CI 11.4-107.9). CONCLUSION: This study demonstrated that smoking opium is associated with a high risk of lung cancer as an independent risk factor.

Prophylactic belladonna suppositories on anesthetic recovery after robotic assisted laparoscopic prostatectomy.

INTRODUCTION: Two prospective trials have demonstrated prophylactic antimuscarinics following prostatectomy reduce pain from bladder spasms. Our practice adopted the routine administration of prophylactic belladonna and opium (B&O) suppositories to patients undergoing robotic assisted laparoscopic radical prostatectomy (RALP). The aim of this study is to determine if this change in clinical practice was associated with improvement of postoperative outcomes. MATERIALS AND METHODS: The medical records of 202 patients that underwent RALP surgery who were or were not administered prophylactic B&O suppositories in the immediate postoperative period were abstracted for duration of anesthesia recovery, pain and analgesic use. RESULTS: Patient and surgical characteristics between groups were similar except B&O group were slightly older (p = 0.04) and administered less opioid analgesics (p = 0.05). There was no difference between groups in the duration of phase I recovery from anesthesia (p = 0.96). Multivariable adjustments for age, body mass index, American Society of Anesthesiologists physical status, and surgical duration were made, and again it was found that suppository administration had no association with phase I recovery times (p = 0.94). The use of antimuscarinic medication for bladder spams in the B&O group was less during phase I recovery (p < 0.01), but was similar during the first 24 hours (p = 0.66). Postoperative sedation, opioid analgesic requirements and pain scales were similar during phase I recovery and the first 24 postoperative hours. Hospital length of stay was similar. DISCUSSION: The introduction of prophylactic B&O suppositories at the immediate conclusion of RALP surgery was not associated with improvements of the postoperative course.

OBJECTIVE: To optimize the extracting condition of fatty constituents from Tabanus bivittatus and analyse by GC-MS. METHODS: Taking fatty yield as index, the extraction technology parameters of fatty constituents of Tabanus bivittatus ere optimized by single factor test and orthogonal test. RESULTS: The optimum extraction parameters were as follows: the ratio of acetone to petroleum ether 1: 2, extraction time 2 h, solid-liquid ratio 1: 50. Twenty-one fatty acids were identified by GC-MS. CONCLUSION: The process is reasonable and with good reproducibility. The main components of fatty acids in Tabanus bivittatus are palmitoleic acid, palmitic acid, linoleic acid, oleic acid and stearic acid.

A model for homeopathic remedy effects: low dose nanoparticles, allostatic cross-adaptation, and time-dependent sensitization in a complex adaptive system.

BACKGROUND: This paper proposes a novel model for homeopathic remedy action on living systems. Research indicates that homeopathic remedies (a) contain measurable source and silica nanoparticles heterogeneously dispersed in colloidal solution; (b) act by modulating biological function of the allostatic stress response network (c) evoke biphasic actions on living systems via organism-dependent adaptive and endogenously amplified effects; (d) improve systemic resilience. DISCUSSION: The proposed active components of homeopathic remedies are nanoparticles of source substance in water-based colloidal solution, not bulk-form drugs. Nanoparticles have unique biological and physico-chemical properties, including increased catalytic reactivity, protein and DNA adsorption, bioavailability, dose-sparing, electromagnetic, and quantum effects different from bulk-form materials. Trituration and/or liquid succussions during classical remedy preparation create "top-down" nanostructures. Plants can biosynthesize remedy-templated silica nanostructures. Nanoparticles stimulate hormesis, a beneficial low-dose adaptive response. Homeopathic remedies prescribed in low doses spaced intermittently over time act as biological signals that stimulate the organism's allostatic biological stress response network, evoking nonlinear modulatory, self-organizing change. Potential mechanisms include time-dependent sensitization (TDS), a type of adaptive plasticity/metaplasticity involving progressive amplification of host responses, which reverse direction and oscillate at physiological limits. To mobilize hormesis and TDS, the remedy must be appraised as a salient, but low level, novel threat, stressor, or homeostatic disruption for the whole organism. Silica nanoparticles adsorb remedy source and amplify effects. Properly-timed remedy dosing elicits disease-primed compensatory reversal in direction of maladaptive dynamics of the allostatic network, thus promoting resilience and recovery from disease. SUMMARY: Homeopathic remedies are proposed as source nanoparticles that mobilize hormesis and time-dependent sensitization via non-pharmacological effects on specific biological adaptive and amplification mechanisms. The nanoparticle nature of remedies would distinguish them from conventional bulk drugs in structure, morphology, and functional properties. Outcomes would depend upon the ability of the organism to respond to the remedy as a novel stressor or heterotypic biological threat, initiating reversals of cumulative, cross-adapted biological maladaptations underlying disease in the allostatic stress response network. Systemic resilience would improve. This model provides a foundation for theory-driven research on the role of nanomaterials in living systems, mechanisms of homeopathic remedy actions and translational uses in nanomedicine.

[Apoptotic mechanism of gecko crude peptides on human liver carcinoma cell line HepG2].

OBJECTIVE: To investigate the effect of Gecko crude peptides (GCPS) on human liver carcinoma HepG2 cells and its mechanism. METHODS: MTT assay was used to analyze the effect of the GCPS on the proliferation of HepG2 Cell; Nucleus change of HepG2 treated with GCP was observed by Hoechst33258 fluorescence staining, and BAX and BCL-2 were detected with western-blot assay. RESULTS: GCPS could inhibit the proliferation of HepG2 Cell in a time and dosage dependent way, and its half-maximal inhibitory concentration (IC50) was 1.2 mg/mL; HepG2 pretreated with GCPS showed apoptotic morphological changes. GCPS (1.6 mg/mL, 0.8 mg/mL) could decrease the expression of BCL-2 protein, and increase the expression of BAX protein. CONCLUSION: GCPS can inhibit the proliferation of HepG2 cell. The mechanism may be related to the induction apoptosis of HepG2.

Classical homeopathy in the treatment of cancer patients--a prospective observational study of two independent cohorts.

BACKGROUND: Many cancer patients seek homeopathy as a complementary therapy. It has rarely been studied systematically, whether homeopathic care is of benefit for cancer patients. METHODS: We conducted a prospective observational study with cancer patients in two differently treated cohorts: one cohort with patients under complementary homeopathic treatment (HG; n = 259), and one cohort with conventionally treated cancer patients (CG; n = 380). For a direct comparison, matched pairs with patients of the same tumour entity and comparable prognosis were to be formed. Main outcome parameter: change of quality of life (FACT-G, FACIT-Sp) after 3 months. Secondary outcome parameters: change of quality of life (FACT-G, FACIT-Sp) after a year, as well as impairment by fatigue (MFI) and by anxiety and depression (HADS). RESULTS: HG: FACT-G, or FACIT-Sp, respectively improved statistically significantly in the first three months, from 75.6 (SD 14.6) to 81.1 (SD 16.9), or from 32.1 (SD 8.2) to 34.9 (SD 8.32), respectively. After 12 months, a further increase to 84.1 (SD 15.5) or 35.2 (SD 8.6) was found. Fatigue (MFI) decreased; anxiety and depression (HADS) did not change. CG: FACT-G remained constant in the first three months: 75.3 (SD 17.3) at t0, and 76.6 (SD 16.6) at t1. After 12 months, there was a slight increase to 78.9 (SD 18.1). FACIT-Sp scores improved significantly from t0 (31.0 - SD 8.9) to t1 (32.1 - SD 8.9) and declined again after a year (31.6 - SD 9.4). For fatigue, anxiety, and depression, no relevant changes were found. 120 patients of HG and 206 patients of CG met our criteria for matched-pairs selection. Due to large differences between the two patient populations, however, only 11 matched pairs could be formed. This is not sufficient for a comparative study. CONCLUSION: In our prospective study, we observed an improvement of quality of life as well as a tendency of fatigue symptoms to decrease in cancer patients under complementary homeopathic treatment. It would take considerably larger samples to find matched pairs suitable for comparison in order to establish a definite causal relation between these effects and homeopathic treatment.

Opium consumption and coronary atherosclerosis in diabetic patients: a propensity score-matched study.

There is a traditional belief among Eastern people that opium may have ameliorating effects on cardiovascular risk factors, especially diabetes; thus, it is widely used among diabetic patients. We attempted to investigate the association of opium consumption with coronary artery disease (CAD) in diabetic patients. A cross-sectional study was conducted on diabetic patients undergoing coronary angiography in our center. Out of 1925 diabetic patients included in the study, 228 were opium users, and the remaining 1697 non-opium users were used as a pool of potential comparators. Propensity scores were used to match the 228 opium consumers with 228 matched comparators for age, sex, and smoking status. The Gensini score and extent score were respectively used to assess the angiographic severity and extent of CAD. The mean Gensini score (86.9 ± 62.7 vs. 59.6 ± 43.4, p < 0.0001) and extent score (7.1 ± 2.9 vs. 5.9 ± 2.9, p < 0.0001) were significantly higher in opium user diabetic patients than in non-opium users. After adjustment for potential confounders, a dose-response relationship was observed between dose of opium and the Gensini score ( ß = 0.27, p = 0.04). There were no significant differences between the routes of opium administration (inhalation vs. oral) regarding the severity and extent of CAD. In conclusion, exposure to opium in diabetic patients may be positively associated with the risk of CAD, and with the angiographically determined severity and extent of the disease. Furthermore, dosage of opium consumption may correlate with severity of CAD.
