Potential Hepatoprotective Effect of Cheatomorpha gracilis extract against High Fat Diet (HFD)-Induced Liver Damage, and its characterization by HPLC / Efeito Hepatoprotetor Potencial do Extrato de Cheatomorpha gracilis contra Dano Hepático Induzido por Dieta Alta em Gordura (HFD), e sua caracterização por HPLC

The current investigation was carried out to estimate the protective effect of aqueous extract of Cheatomorpha gracilis (AEC) against High fat Diet (HFD) induced liver damage in mice. The results of the in vitro study showed that AEC have higher antioxidant capacities in the DPPH and hydroxyl radical-scavenging assays. Indeed, many phenolic compounds (gallic acid, quercetin, naringenin, apigenin, kaempferol and rutin) were identified in the AEC. In the animal studies, during 6 weeks, HFD promoted oxidative stress with a rise level of malonaldehyde (MDA), protein carbonyls (PCOs) levels and a significant decrease of the antioxidant enzyme activities such as superoxide dismutase, catalase and glutathione peroxidase. Interestingly, the treatment with AEC (250 mg/kg body weight) significantly reduced the effects of HFD disorders on some plasmatic liver biomarkers (AST, ALT and ALP) in addition to, plasmatic proteins inflammatory biomarkers (α2 and ß1 decreases / ß2 and γ globulins increases). It can be suggest that supplementation of MECG displays high potential to quench free radicals and attenuates high fat diet promoted liver oxidative stress and related disturbances.

De fato, muitos compostos fenólicos (ácido gálico, quercetina, naringenina, apigenina, kaempferol e rutina) foram identificados no AEC. Nos estudos em animais, durante 6 semanas, HFD promoveu estresse oxidativo com aumento do nível de malonaldeído (MDA), níveis de proteína carbonil (PCOs) e diminuição significativa das atividades de enzimas antioxidantes como superóxido dismutase, catalase e glutationa peroxidase. Curiosamente, o tratamento com AEC (250 mg / kg de peso corporal) reduziu significativamente os efeitos dos distúrbios de HFD em alguns biomarcadores hepáticos plasmáticos (AST, ALT e ALP), além de biomarcadores inflamatórios de proteínas plasmáticas (reduções α2 e ß1 / ß2 e γ aumenta as globulinas). Pode-se sugerir que a suplementação de MECG apresenta alto potencial para extinguir os radicais livres e atenua o estresse oxidativo do fígado promovido pela dieta rica em gordura e distúrbios relacionados.

Determination of occlusal vertical dimension for complete dentures patients: an updated review.

Determination of the occlusal vertical dimension (OVD) is an integral part of complete dentures fabrication. Due to the lack of teeth, the clinician faces the challenge of how to accurately establish the OVD of the new denture. Therefore, the purpose of this review article was to present, discuss and critique the available methods used in determining the OVD for complete dentures patients. This review identified two main streams to determine the OVD: (i) pre-extraction methods and (ii) post-extraction methods. For the pre-extraction methods, the OVD of the natural dentition is transferred to the new dentures mainly by intra-oral measurements, profile tracing and cephalometric analysis. The post-extraction methods rely on mandibular rest position, facial aesthetic appearance, swallowing pattern, craniofacial landmarks measurements, cephalometric analysis, phonetics and existing dentures. In general, all the available techniques have merits and are helpful for routine clinical use. However, they are empirical in nature, controversial and lack the scientific support. Further, there is no single accurate method for OVD determination. To overcome the limitations of the techniques, the clinician will benefit from applying combination of techniques to approximate the OVD.

DJ-1 upregulates breast cancer cell invasion by repressing KLF17 expression.

BACKGROUND: DJ-1 (PARK7) was reported as an oncogene in a Ras-dependent manner. Recent studies have shown that DJ-1 stimulates cell proliferation, cell invasion, and cancer metastasis. However, the molecular mehchanism by which DJ-1 induces cancer cell invasion and metastasis remains unclear. METHODS: Breast cancer cells were transfected with DJ-1 siRNA or DJ-1 overexpression to investigate the effect of DJ-1 on KLF17 expression. ID-1 luciferase promoter assay was performed to evaluate DJ-1-dependent KLF17 expression changes. In addition, Epistasis analysis of DJ-1 and KLF17 was performed to evaluate their regulatory interactions. Ras inhibitors were pretreated to determine whether DJ-1 regulates cell invasion in a Ras-dependent manner. RESULTS: I n the present study, we found increased DJ-1 expression in highly invasive breast cancer cells as compared with non-metastatic cells. Furthermore, DJ-1 promoted breast cancer cell invasion by downregulating E-cadherin and increasing Snail expression. Interestingly, exogenous DJ-1 overexpression markedly decreased mRNA and protein expression of KLF17, the EMT negative regulator. These data were confirmed by ID-1 promoter activity, which is directly regulated by DJ-1-dependent KLF17 transcription factor. Epistasis analysis showed that KLF17 overexpression overcomes increased cell invasion by DJ-1, suggesting that KLF17 might be one of the downstream signalling molecules of DJ-1. Acceleration of cell invasion by DJ-1 was alleviated by Ras inhibitors, suggesting that DJ-1 cooperates with Ras to increase cell invasion. CONCLUSION: Altogether, these data suggest for the first time that DJ-1 acts as an EMT-positive regulator in breast cancer cells via regulation of the KLF17/ID-1 pathway.

Measurement of thermal characteristics of spray-dried milk and juice blend.

Blended concentrated grape/peach (G/P) juice 60% total soluble solids (TSS) with condensed whole cow milk 40% TSS (1.5:8.5) was spray dried using a pilot-scale spray drier FT 80 at feeding pressure 7,000 Pa, at chamber temperature 180 degrees C and at chamber pressure -110 Pa. The glass transition state of blended G/P juice-milk powder, three pure sugars (glucose, sucrose and lactose) and casein were studied using differential scanning calorimetry. The calorimetry showed that G/P juice-milk powder is a glassy material. The glass transition temperature of blended G/P juice-milk powder at 0.248 water activity was 42 degrees C, compared with commercial full milk powder (control) of 29 degrees C at 0.334 at water activity (a(w)).

[The possibilities of early diagnosis of tumorous lesions of colon patency and their preoperative correction].

Experiments in white rats were used in order 1) to create a model of obturative colon obstruction (OCO) and to prove a staged character of its development depending on the tone of the Bauhin's valve (the normotonic phase, spasm of the Bauhin's valve, dilatation of the Bauhin's valve) and 2) to study specific features of healing primary anastomoses after emergency resections of the colon. An analysis of clinical and rentgenological findings has confirmed the staged character of tumor lesions of the colon patency (TLCP). A working classification of them is proposed: stages of compensation (conventionally chronic); subcompensation (subacute) with three degrees of stages according to the experimental scheme of pathogenesis; decompensated (acute obturative colon obstruction). Typical rentgenological symptoms are first described and systematized for the stages of sub- and decompensation. In combination with the classification they make the basis for early diagnosis of TLCP, establishment of absolute indications for urgent operations and decision for the early intraoperative strategy. An original three-lumen probe for preoperative decompression and monitory purgation of the intestine, the method of intra- and postoperative decompression, correction of the intraintestinal status allowed to form primary anastomoses after urgent resections of the colon in 170 (63.7%) out of 317 patients with OCO. A scheme of control with the help of thermo-transducer is proposed for prognosis of a possible failure of the anastomosis.

Knowledge and practice of complementary medicine amongst public primary care clinic doctors in Kinta district, Perak.

The knowledge and practice of doctors (n=40) towards complementary medicine (CM) in 16 health clinics in the Kinta District were assessed by questionnaire. Thirty-four (85%) responded. More than half felt that acupuncture (73.50), homeopathy (59%) and herbal medicine (59%) were occasionally harmful. Forty-four percent felt manipulative therapy was frequently harmful. Relaxation technique (79%) and nutritional therapy (44%) were considered most frequently useful. 59% used some form of CM. There were no significant differences found in usage rates by gender, age group and exposure to CM during undergraduate training. Sixty-seven percent had encouraged patients to seek CM. Seventy-three percent perceived an increasing demand for CM. Eighty-eight percent were in favour of a hospital based CM referral center. Only 6% were trained in CM.

A naturalistic study of the use of vigabatrin, lamotrigine and gabapentin in adults with learning disabilities.

Epilepsy is a common condition in people with learning disabilities with many patients continuing to suffer from seizures despite antiepileptic drug (AED) treatment. Although the advent of newer AEDs offers hope for better treatment, there is a need to compare the efficacy of each new AED in adults with both drug-resistant epilepsy and learning disabilities. This retrospective casenote study involves the analysis of the outcome for those adults with learning disabilities treated with either vigabatrin, lamotrigine or gabapentin. The information obtained from the casenote analysis was used to both compare the efficacies of the three drugs and also the side-effects and drop-out rates, including reasons for drop-out. The total number of patients involved was 51 who underwent 71 treatment episodes. All three AEDs had similar efficacies. Although vigabatrin was found to be associated with a higher incidence of behaviour problems, behaviour problems occurred with the other drugs as well. Lamotrigine caused increased seizures in 24% of patients, especially when prescribed at a higher dose. Gabapentin appeared to be associated with fewer serious side-effects.

A comparison of statistical techniques to evaluate the performance of the Glucometer Elite blood glucose meter.

OBJECTIVES: The objective of the study was to measure the performance of the Glucometer Elite, a technique-independent device for self-monitoring of capillary blood glucose. Several potential sources of error were incorporated into the study, including variability between lots, the age of a lot, variability between subjects, and variability between strips. DESIGN AND METHODS: The Glucometer Elite was tested using capillary samples from 86 individuals. Duplicate readings with each of 8 sensor lots were done for each participant. Glucometer Elite readings were compared to YSI capillary plasma equivalent values, and the data was evaluated using a variety of both technical and clinical analysis methods. RESULTS: All evaluation methods showed excellent agreement between the Glucometer Elite and the YSI plasma equivalent values. CONCLUSION: The Glucometer Elite system provides accurate and clinically valuable information to the diabetic home tester.

Psychiatric disorder in Asian adults with learning disabilities: patterns of service use.

Asian and white Caucasian adults with learning disabilities seen by the Department of the Psychiatry of Learning Disabilities, Frith Hospital, Leicester, England, in 1991 were studied. Asian adults with learning disabilities were under-represented with respect to the local population (as measured by learning disability register), but not the population of individuals with learning disabilities known to the psychiatric services. Asians were significantly more likely to receive a psychiatric diagnosis, in particular that of psychosis, but there were striking similarities in the routes of referral, the number of contacts with the service and the range of defined disabilities.

Multi-infarct dementia in Down's syndrome.

In spite of a burgeoning literature on the association of Down's syndrome with Alzheimer's disease, the occurrence of multi-infarct dementia has largely been overlooked. A 55-year-old woman with Down's syndrome in whom a dementing process was associated with evidence of significant cerebrovascular disease is reported here. It is considered that she sustained both multi-infarct dementia and probable Alzheimer's disease. It is suggested that such cases are under-reported.

Antiparietal cell antibodies in gastritis associated with chronic liver diseases.

Thirty patients with gastritis associated with chronic liver disease and ten normal controls were the subject of this study. Pathologically about 18 were diagnosed as chronic atrophic gastritis, 10 as chronic superficial gastritis, 1 as gastric atrophy and 1 as hypertrophic gastritis. Parietal cell antibodies (PCA) were detected (IFA) in 2 cases with no significant relation.

Lithium in the treatment of aggression in mentally handicapped patients. A double-blind trial.

In a double-blind trial lasting 4 months in 42 mentally handicapped patients, the effect of lithium on aggression was assessed in comparison with placebo. In the lithium-treated group, 73% of patients showed a reduction in aggression during treatment. There were significant differences in mean weekly aggression scores and in the frequency of aggressive episodes between the lithium and placebo groups. Side-effects were noted in 36% of the lithium group (and 20% of the placebo group), but were mainly transitory. There were no episodes of toxicity, and no patients had to be withdrawn from the trial. Lithium appears to be worth a 2-month trial in such patients, where repeated aggression has not been relieved by more appropriate placement, occupation or company.

Responses of Anopheles minimus to DDT residual spraying in a cleared forested foothill area in central Thailand.

Anopheles balabacensis balabacensis and Anopheles minimus are the main malaria vectors in Thailand. In a cleared forested foothill area in the central part of the country A. minimus was the most prevalent anopheline species found, only 6 specimens of A. b. balabacensis being collected over a 3-year period. Cattle were scarce in the area, tractors being largely used for working in the fields. This situation contributed to high man-vector contact. A minimus occurred throughout the year, with a major peak of density in the dry cool season and a smaller peak in the wet season. The contact of A. minimus with man was much higher outdoors than indoors, and studies showed the species to be an early biter, especially in the dry season, thus increasing the chance of man-vector contact. DDT spraying appeared to reduce considerably the estimated vectorial capacities, however, this effect was not maintained and malaria transmission was not interrupted. Trials with supplementary or alternative attack measures are therefore indicated in this particular ecological situation.
