RESUMO
Objectives: To ascertain whether a link exists between vitamin D insufficiency and early childhood caries or not. Method: From the out patient department (OPD) of the Pedodontics Department at Vyas Dental College, a random sample of 40 kids between the ages of 8 months and 5 years old was chosen. Each kid had blood drawn to check their serum 25(OH) vitamin D levels. All of the data was collated and given the necessary statistical analysis. Result: The case group's mean serum 25(OH) vitamin D level was 10.19 ng/mL (with a standard deviation of 3.46), while the control group's was 20.84 ng/mL (2.54 SD). Conclusion: A significant modifiable risk factor for childhood dental caries is a vitamin D deficiency. Therefore, cavities in teeth can be avoided by giving youngsters vitamin D supplements and avoiding vitamin D insufficiency.
RESUMO
Birth related perineal trauma (BRPT) and obstetric anal sphincter injuries (OASIS) are leading causes of anal incontinence in women, which negatively impacts on their quality of life, resulting in low self-esteem and abandonment. In low resource countries (LRC), the true incidence is not known and since most births are unattended or occur in community-based health care systems, one can anticipate that it is a significant problem. Dissemination of information to women, education of traditional birth attendants, improvement of resources and transport, and training of health professionals on the detection and appropriate surgical management of these injuries will reduce morbidity and improve outcome. Intrapartum measures such as controlled head descent and perineal support, correct episiotomy techniques and selective use of instruments to assist vaginal births is pivotal in avoiding these injuries. Policy makers should prioritize maternity care in LRC, and research is urgently needed to address all aspects of BRPT.

OBJECTIVES: This study examined residents' attitudes and practices regarding the relevance of spirituality in psychiatry within Saudi residency training programs; their experiences and comfort levels in addressing patients' spiritual concerns; and their interest and past learning experiences in this area of training and practice. METHODS: This cross-sectional study targeted trainees and recent graduates of residency programs across Saudi Arabia. The study materials consisted of an electronic questionnaire that was adapted with permission. RESULTS: The total number of respondents was 71 out of 180 potential participants (39.44%). Most residents (64.8%) felt that it was appropriate to inquire about the spiritual aspects of patients' lives and that it was essential to address spiritual problems or needs that patients may have within the clinical setting (71.8%). Many participants (40.80%) described themselves as being both religious and spiritual. Most respondents (94.4%) did not receive any training on spirituality and psychiatry, and 80.3% said they would like to learn more about the subject. CONCLUSIONS: Our findings indicate that residents have an overall high level of personal spirituality and that they feel it is relevant in clinical practice. However, they have not had much training in this area and are interested in learning more. Educational initiatives would be beneficial for improving the effectiveness of residents and patient care in this untapped area of spirituality in psychiatry.
RESUMO
Background: Compassion satisfaction (CS) is a phenomenon that has been studied among the helping professions, such as nursing and social work and has been linked to stress, burnout, compassion fatigue, and vicarious trauma. Social work educators may also experience these same issues, yet more research is needed on how they might counter the negative impacts associated with this type of work by utilizing their experiences of CS. Objectives: A phenomenological study was carried out to explore and describe how social work educators in higher education experiences CS. Methods: Eleven in-depth interviews with social work educators were conducted, and constructivist grounded theory techniques were utilized to analyze the data. Results: Social work educators experienced CS within the education and personal realms, which encompassed four different elements: achievement, support, balance, and empathy. Discussion: The four elements of CS were utilized by social work educators in this study as coping strategies to enhance their experience of CS, thus encountering threats to CS, such as institutional barriers, interaction with administrators and colleagues, and work overload. Conclusion: Interventions fostering compassion satisfaction and reducing compassion fatigue, burnout, and stress should be considered, including interventions that increase the sense of accomplishment, promote holistic self-care, encourage administrative and collegial support, and improve work-life balance.
RESUMO
Heat stress (HS) is one of the most severe hurdles impacting rabbit growth, immunity, homeostasis, and productivity. Alginate oligosaccharides (AOS) have considerable beneficial effects due to their plausible antioxidant and immune-stimulatory properties. This work was planned to explore the preventive function of AOS as a new bio-feed additive against the harmful effects caused by environmental HS on growing rabbits. Rabbits were allotted in four experimental groups (25 animals in each group) and fed on a basal diet supplemented with 0.0 (AOS0), 50 (AOS50), 100 (AOS100), and 150 (AOS150) mg AOS/kg diet reared under summer conditions. Dietary AOS supplementation improved significantly (P ≤ 0.001) feed conversion rate, while both AOS100 and AOS150 significantly (P ≤ 0.001) enhanced the final body weight and body weight gain. All AOS addition significantly increased nitric oxide and lysosome activity and significantly reduced interferon-gamma (IFNγ) compared with those in the control group. Tumor necrosis factor α (TNFα), interleukin1ß (IL-1ß), myeloperoxidase and protein carbonyl levels were significantly reduced in rabbits fed diets containing AOS (100 and 150 mg/kg) compared with those in the control group under heat stress conditions. In addition, glutathione (GSH) and catalase (CAT) were significantly (P ≤ 0.001) improved with increasing AOS dietary levels compared with the control group. Still, total antioxidant capacity (TAC), malondialdehyde (MDA), hematocrit, mean corpuscular volume (MCV), eosinophils, and lymphocytes did not change. Erythrocyte's indices improved significantly (P ≤ 0.001), while neutrophils and white blood cell counts were decreased by dietary AOS inclusion. Immunological (IgM and IgG) were markedly reduced in AOS-treated groups compared with the control group. The current investigation exemplified that AOS as a novel bio-feed additive that could be an effective strategy to extenuate prejudicial effects in heat-stressed rabbits via enhancing immunity, and antioxidant defence system, further regulating the inflammation cytokines.

Diabetes mellitus is a metabolic disorder and is a global challenge to the current medicinal chemists and pharmacologists. This research has been designed to isolate and evaluate antidiabetic bioactives from Fragaria indica. The crude extracts, semi-purified and pure bioactives have been used in all in vitro assays. The in vitro α-glucosidase, α-amylase and DPPH free radical activities have been performed on all plant samples. The initial activities showed that ethyl acetate (Fi.EtAc) was the potent fraction in all the assays. This fraction was initially semi-purified to obtain Fi.EtAc 1-3. Among the semi-purified fractions, Fi.EtAc 2 was dominant, exhibiting potent IC50 values in all the in vitro assays. Based on the potency and availability of materials, Fi.EtAc 2 was subjected to further purification to obtain compounds 1 (2,4-dichloro-6-hydroxy-3,5-dimethoxytoluene) and 2 (2-methyl-6-(4-methylphenyl)-2-hepten-4-one). The two isolated compounds were characterized by mass and NMR analyses. The compounds 1 and 2 showed excellent inhibitions against α-glucosidase (21.45 for 1 and 15.03 for 2 µg/mL), α-amylase (17.65 and 16.56 µg/mL) and DPPH free radicals (7.62 and 14.30 µg/mL). Our study provides baseline research for the antidiabetic bioactives exploration from Fragaria indica. The bioactive compounds can be evaluated in animals-based antidiabetic activity in future.

OBJECTIVE: The present study was aimed at investigating the possible antiulcer activities of some natural phytochemicals Aloe perryi leaf extract (APLE) and flower extract (APFE) in addition to the date palm seed extract (DPSE) and the oily samples of DPSE in a pylorus ligation-induced ulcer model using ranitidine as a standard antiulcer drug. BACKGROUND: Peptic ulcer is a prevalent gastrointestinal disorder due to hypersecretion of gastric acid. It affects four million people worldwide, and 2-10% of these ulcers are perforated and cause bleeding. This increases the risk of morbidity and mortality. So we aimed to introduce a primary study alternatively safe method for treating peptic ulcer. MATERIALS AND METHODS: Forty-two Wistar Albino rats of either sex were randomly divided into seven groups (6/each). The pylorus ligation was done to induce ulcer in pretreated albino rats. The antiulcer activities of extracts were estimated at different dose levels (250 and 500 mg/kg) using ranitidine as a standard drug (50 mg/kg). Gastric volume, pH, and total and free acidity as well as ulcer index and percentage of ulcer inhibition were measured to elucidate the antiulcerogenic effects. Histological examination of gastric ulcer was also performed. Statistical analysis for the results was done where P < 0.05 was considered statistically significant. RESULTS: Pylorus ligation for 6 h in control rats resulted in gastric ulcer which was indicated by the accumulation of gastric secretion and increased total acidity and decreased pH. The pretreatment of rats with APLE, APFE, and DPSE in addition to the oily samples of DPSE significantly inhibited the ulcers induced by pylorus ligation. These effects were attributed to significant reductions in total and free acidity, ulcer index, and gastric volume while there is a marked decrease in gastric pH (the antisecretory) as well as mucosal strengthening properties of these phytochemicals. CONCLUSION: These findings give these extracts the potential to be a promising tool for the management of gastric ulcer after performing further clinical and experimental studies. Our study demonstrated the promising antiulcer activity of extracts and oils in pyloric ligation-induced gastric ulcer. To the best of our knowledge, this is the first study to explore the antiulcer activity of these extracts; however, further investigations may be recommended for full details about this antiulcerogenic capacity.

BACKGROUND: Natural phenolic compounds and Phenolics-rich medicinal plants are also of great interest in the management of diabetes. The current study was aimed to analyze phenolics in P. hydropiepr L extracts via HPLC-DAD analysis and assess their anti-diabetic potentials using in-vitro and in-silico approaches. METHODS: Plant crude methanolic extract (Ph.Cme) was evaluated for the presence of phenolic compounds using HPLC-DAD analysis. Subsequently, samples including crude (Ph.Cr), hexane (Ph.Hex), chloroform (Ph.Chf), ethyl acetate (Ph.EtAc), butanol (Ph.Bt), aqueous (Ph.Aq) and saponins (Ph.Sp) were tested for α-glucsidase and α-amylase inhibitory potentials and identified compounds were docked against these target enzymes using Molecular Operating Environment (MOE) software. Fractions were also analyzed for the nutritional contents and acute toxicity was performed in animals. RESULTS: In HPLC-DAD analysis of Ph.Cme, 24 compounds were indentfied and quantified. Among these, Kaemferol-3-(p-coumaroyl-diglucoside)-7-glucoside (275.4 mg g- 1), p-Coumaroylhexose-4-hexoside (96.5 mg g- 1), Quercetin-3-glucoronide (76.0 mg g- 1), 4-Caffeoylquinic acid (58.1 mg g- 1), Quercetin (57.9 mg g- 1), 5,7,3'-Trihydroxy-3,6,4',5'-tetramethoxyflavone (55.5 mg g- 1), 5-Feruloylquinic acid (45.8 mg g- 1), Cyanidin-3-glucoside (26.8 mg g- 1), Delphinidin-3-glucoside (24 mg g- 1), Quercetin-3-hexoside (20.7 mg g- 1) were highly abundant compounds. In α-glucosidase inhibition assay, Ph.Sp were most effective with IC50 value of 100 µg mL-1. Likewise in α-amylase inhibition assay, Ph.Chf, Ph.Sp and Ph.Cme were most potent fractions displayed IC50 values of 90, 100 and 200 µg mL-1 respectively. Docking with the α-glucosidase enzyme revealed top ranked conformations for majority of the compounds with Kaemferol-3-(p-coumaroyl-diglucoside)-7-glucoside as the most active compound with docking score of - 19.80899, forming 14 hydrogen bonds, two pi-H and two pi-pi linkages with the Tyr 71, Phe 158, Phe 177, Gln 181, Arg 212, Asp 214, Glu 276, Phe 300, Val 303, Tyr 344, Asp 349, Gln 350, Arg 439, and Asp 408 residues of the enzyme. Likewise, docking with α-amylase revealed that most of the compounds are well accommodated in the active site residues (Trp 59, Tyr 62, Thr 163, Leu 165, Arg 195, Asp 197, Glu 240, Asp 300, His 305, Asp 356) of the enzyme and Cyanidin-3-rutinoside displayed most active compound with docking score of - 15.03757. CONCLUSIONS: Phytochemical studies revealed the presence of highly valuable phenolic compounds, which might be responsible for the anti-diabetic potentials of the plant samples.

Colonic atresia (CA) is the rarest type of intestinal atresia and is defined as an obstruction in the large intestinal lumen. This is a rare case presentation of a four-day-old full-term female patient presented with signs and symptoms of intestinal obstruction. Investigation revealed that she had complicated CA located in the splenic flexure. Laparotomy and colostomy were done on the patient. About two months later, she was admitted for stoma closure, which was converted to modified Bishop-Koop stoma. Lastly, the patient underwent a successful stoma closure. Upon one month of follow-up, the patient's condition has markedly improved and the wound healed well without any complications.
RESUMO
As a crucial organ, the lung is exposed to various harmful agents that may induce inflammation and oxidative stress, which may cause chronic or acute lung injury. Nigella sativa, also known as black seed, has been widely used to treat various diseases and is one of the most extensively researched medicinal plants. Thymoquinone (TQ) is the main component of black seed volatile oil and has been proven to have antioxidant, anti-inflammatory, and antineoplastic properties. The potential therapeutic properties of TQ against various pulmonary disorders have been studied in both in vitro and in vivo studies. Furthermore, the application of nanotechnology may increase drug solubility, cellular absorption, drug release (sustained or control), and drug delivery to lung tissue target sites. As a result, fabricating TQ as nanoparticles (NPs) is a potential therapeutic approach against a variety of lung diseases. In this current review, we summarize recent findings on the efficacy of TQ and its nanotypes in lung disorders caused by immunocompromised conditions such as cancer, diabetes, gastric ulcers, and other neurodegenerative diseases. It is concluded that TQ nanoparticles with anti-inflammatory, antioxidant, antiasthma, and antitumor activity may be safely applied to treat lung disorders. However, more research is required before TQ nanoparticles can be used as pharmaceutical preparations in human studies.

OBJECTIVES: To assess the efficacy of triphala mouthwash (TRP-MW) in being equally effective to chlorhexidine mouthwash (CHX-MW) in the treatment of plaque-induced gingivitis. MATERIALS AND METHODS: Electronic searches in MEDLINE/PubMed, EMBASE and CENTRAL were conducted in databases up to April 2020. Randomized clinical trials (RCTs) comparing clinical efficacy of TRP-MW (test group) in comparison with CHX-MW in treating plaque-induced gingivitis were considered. The primary outcome was gingival index (GI), whereas the secondary outcome was plaque index (PI). RESULTS: Seven RCTs were included. All studies showed that TRP-MW administration was significantly effective as compared to CHX-MW in the treatment of plaque-induced gingivitis. Considering the effects of TRP-MW on clinical gingival inflammatory parameters, significant heterogeneity for both GI (χ2 = 72.77, P < .0001, I2 = 91.76%) and PI (χ2 = 153.67, P < .0001, I2 = 96.10%) was observed between both TRP-MW and CHX-MW groups. The overall mean difference for both GI (WMD = -0.29, 95% CI = -0.40 to -0.17, P < .001) and PI (WMD = -0.43, 95% CI = -0.54 to -0.31, P < .001) was statistically significant between TRP-MW and CHX-MW at follow-up, respectively. CONCLUSION: Triphala mouthwash seems to significantly improve the clinical gingival inflammatory parameters in plaque-induced gingivitis with equal clinical efficacy as CHX-MW. TRP is a cost-effective alternative and is easily available with limited side effects on periodontal tissues.

AIM: The aim of the present study was to evaluate the antibacterial efficacy of various concentrations of Eucalyptus globulus leaf extract on periodontal pathogens. MATERIALS AND METHODS: Matured, healthy and disease-free leaves of Eucalyptus globulus were collected. The leaves were washed under tap water and finally dried in an oven at a temperature of 45°C for 48 hours. The dried plants were ground in an electric blender to make them into a powder. The powder was mixed with 100% ethanol and kept it inside a shaker overnight at 35°C. The mixture was centrifuged for 10 minutes at 2,500 rpm. Three different concentrations (10%, 50%, and 100% v/v) were used as antibacterial agents. Chlorhexidine (0.2%) was considered as positive control and dimethyl formamide was considered as negative control against P. gingivalis and A. actinomycetemcomitans. The disc diffusion method was used to determine the extract's antibacterial activity against the test organisms. A digital Vernier caliper was used to measure the diameter of antibacterial activity showing the zone of inhibition in millimeters. RESULTS: Eucalyptus globulus with 100% concentration showed a maximum zone of inhibition against A. actinomycetemcomitans and P. gingivalis (5.38 ± 0.32 mm, 4.82 ± 0.11 mm) followed by 50% and 10% accordingly. The negative control of dimethyl formamide showed a zone of inhibition of 0.48 ± 0.96 mm and 0.63 ± 0.20 mm against A. actinomycetemcomitans and P. gingivalis. The positive control of 0.2% chlorhexidine showed a zone of inhibition of 8.46 ± 1.02 mm and 7.18 ± 0.54 mm against A. actinomycetemcomitans and P. gingivalis. The ANOVA test showed a highly significant antibacterial efficacy in 0.2% chlorhexidine and 100% concentration Eucalyptus globulus. CONCLUSION: A significant maximum zone of inhibition against A. actinomycetemcomitans and P. gingivalis was showed by 100% concentration of Eucalyptus globulus. CLINICAL SIGNIFICANCE: Other than the systemic diseases treatment, Eucalyptus globulus also serves as an effective promising alternative to antibiotics in the prevention of oral infections because of the natural phytochemicals existing in them.

Black women carry the burden of uterine fibroids, (AKA uterine leiomyomas), at a much higher rate than their racial counterparts. Thus, increasing awareness and discovering a solution to an endemic problem that plagues Sub-Saharan Africa is of critical importance, not only for the region itself, but also for the medical community globally. A collaborative, patient oriented, cost effective, and culturally sensitive approach must be at the forefront of this endeavor. While the exact pathogenesis of uterine fibroid development remains elusive, the racial disparity is well documented. Moreover, in the developed world, women are able to seek treatment through surgical and non-surgical means; however, sub-Saharan regions face their own challenges that, if not addressed, can ultimately extinguish the lives of many suffering women. Unfortunately, the literature is scarce on how to prevent fibroid development, which may be critical for women who do not have access to effective interventions. Recent research from our group and others has shown that vitamin D deficiency plays an important role in fibroid development and may be a preventable risk factor. Daily vitamin D supplementation is a low cost, effective intervention that could be implemented throughout the Sub-Saharan region. Similarly, education and increased awareness as to the nature and symptoms of uterine fibroids could improve the quality of life, remove negative social stigma, and reduce morbidity and mortality rates in women who seek medical care with advanced uterine fibroids.
RESUMO
INTRODUCTION: This study was conducted to find out the bacterial causes of early onset neonatal sepsis and their susceptibility pattern for different classes of antibiotics in neonates admitted to neonatal intensive care unit (NICU) of Mansoura-Egypt. METHODS: A descriptive cross-sectional study was conducted. All admitted newborns to our study were infants at <72 hours of age with clinical features of sepsis or product of an in-house delivery at Mansoura University Hospital with risk factors for neonatal sepsis. Identification of Gram-negative isolates was confirmed by API 20E kits (bioMerieux). Antibiotic susceptibility was performed by Kirby-Bauer disc diffusion method. Bacteria resistant to ≥3 antimicrobial classes were counted as multidrug resistant. RESULTS: One hundred eighty eight babies were admitted to our study. Positive blood culture was reported in 34.6% of newborn infants with prevalence of 4.02/1,000 live births. The most common isolated bacteria in early onset neonatal sepsis were coagulase negative staphylococci followed by Klebsiella pneumoniae and Serratia marcescens. The Gram-positive bacteria showed high resistance to ampicillin 93.9% while all the isolates were susceptible to vancomycin. The isolated Gram-negative bacteria were highly resistant to ampicillin [96.9%], amoxicillin-clavulanic acid [90.6%], cefotaxime [84.4%] and ceftazidime [84.4%]. Best sensitivity among all isolates was observed to imipenem. Multidrug resistance was observed among 45.5% of the Gram-positive and 68.8% of Gram-negative isolates. CONCLUSION: Appropriate identification of the source of infection and initiation of an effective management can reduce both mortality and morbidity associated with neonatal sepsis. The challenge is to initiate immediate empirical antibiotic therapy according to a strictly implemented updated antibiotic policy based on an individualized community established antimicrobial sensitivity pattern of microorganisms causing early onset neonatal sepsis.

CONTEXT: Postmenopausal osteoporosis is mostly caused by increased bone remodeling resulting from estrogen deficiency. Hormone replacement therapy (HRT) is used to prevent osteoporosis, but it increases the risk for breast cancer, thromboembolism, strokes, and heart attacks. Pomegranate seed oil extract (SOE) is rich in phytoestrogen and antioxidant compounds. OBJECTIVES: To evaluate the therapeutic role of SOE against bone turnover, resorption and osteoporosis induced in ovariectomized rats as a postmenopausal model and comparing the results with those from Generic CycloProgynova drug (D). DESIGN: The study used western albino rats undergo bilaterally ovariectomization as a model for postmenopausal. SETTING: The study took part in a laboratory setting. ANIMALS: Forty female western albino rats (age: 3-4 months) weighing 150-180 gm. MEASUREMENTS: Rats were divided into four groups, 10 rats each; SC-group: Sham control = untreated and unovariectomized rats; OVX-group = ovariectomized rats; (OVX-SOE) and (OVX-D) groups = OVX rats were treated with SOE and D, respectively. Bone markers (BMs) especially osteocalcin (BGP), alkaline phosphatase (ALP), tartarate resistance acid phosphatase (TRAcP), bone weight, bone calcium concentration, serum electrolytes (calcium, sodium and potassium) and serum estradiol (E2) level and histopathological examination of bones were determined. Also lipid profile, uric acid, prothrombin time (INR) and liver and kidney functions were measured to evaluate the adverse effects of SOE and D. RESULTS: In OVX group the activities of ALP and TRAcP and the levels of BGP, serum calcium, sodium and body weight were significantly higher (p≤0.05) than SC-group, while bone calcium concentration, bone mass, serum E2 and potassium level as well as uterus mass were significantly lower (p≤0.05). Also histopathological results revealed that the outer cortical bone became thinner, while the cancellous bone trabeculae lost their normal architecture. Moreover in OVX group lipid profile and uric acid levels were significantly higher (p≤0.05) than SC group, but there were no significant changes (p≤0.05) in INR level, liver and kidney functions. Treatment of OVX rats with SOE or D for 12 weeks improved both the architecture of bones as shown from the histopathological results and BMs, serum electrolytes and E2 levels (p≤0.05) which approached SC-group. Moreover after treatment of OVX rats with SOE the levels of lipid profile and uric acid were improved and approached SC-group, while liver function became significant lower (p≤0.05) than SC-group. Also there were no significant changes (p≤0.05) in kidney functions and INR of (OVX-SOE), OVX and SC groups. In contrast in (OVX-D) group the levels of lipid profile, liver and kidney functions, uric acid and INR were significantly higher (p≤0.05) than those of OVX and SC groups. CONCLUSION: The results of this study show that SOE has therapeutic effects on osteoporosis, while it has no adverse effects on lipid profile, uric acid, liver and kidney functions when compared to HRT. SOE offers a promising alternative in the design of new strategies in nutritional management of age-related bone complications.

BACKGROUND: Ethanolic extract of G. procumbens leaves has been previously shown to possess antihyperlipidemic effects. OBJECTIVE: This study was designed to prepare caffeoylquinic acids rich and poor fractions of the ethanolic extract using resin column technology and compare their antihyperlipidemic and antioxidant potentials. RESULTS: Among the treatment groups, caffeoylquinic acids rich fraction (F2) and chlorogenic acid (CA, one of the major caffeoylquinic acids) showed potent antihyperlipidemic effects, with significant reductions in total cholesterol (TC), triglycerides (TG), low-density lipoprotein-cholesterol (LDL-C), very low-density lipoprotein-cholesterol (VLDL-C), atherogenic index (AI) and coronary risk index (CRI) (p<0.01 or better) compared to the hyperlipidemic control at the 58 h. The effect was better than that of ethanolic extract. In addition, only F2 significantly increased the high-density lipoproteincholesterol (HDL-C) level (p<0.05). F2 showed better effect than CA alone (60 mg) despite the fact that it only contained 9.81 mg CA/1000 mg dose. The findings suggest that the di-caffeoylquinic acids (86.61 mg/g dose) may also in part be responsible for the potent antihyperlipidemic effect shown by the F2. Likewise, F2 showed the highest antioxidant activity. Thus, simple fractionation of ethanolic extract using the Amberlite XAD-2 resin technique had successfully enriched the caffeoylquinic acids into F2 with improved antihyperlipidemic and antioxidant capacities than that of the ethanolic extract. CONCLUSION: The resin separation technology may find application in caffeoylquinic acids enrichment of plant extracts for pre-clinical studies.

BACKGROUND: Star fruit (Averrhoa carambola) is a well-known plant in Malaysia which bears a great significance in traditional medicine. OBJECTIVES: This study aimed to evaluate the antihyperlipidemic effect, antioxidant potential and cytotoxicity of aqueous and methanolic extracts of ripe and unripe fruits, leaves and stem of A. carambola. METHODS: Antihyperlipidemic activity was assessed in poloxamer-407 (P-407) induced acute hyperlipidemic rat's model. The antioxidant activity was assessed in vitro using 2, 2'-azino-bis (3-ethylbenzthiazoline-6-sulphonic acid) (ABTS) radical scavenging, 1-diphenyl-2-dipicrylhydrazyl radical scavenging (DPPH) and ferric reducing antioxidant power (FRAP) assays. In addition, cytotoxicity of A. carambola extracts was assessed using MTS assay on four leukemic cell lines (human colon cancer, human promyeloid leukemia, erythroid leukemia, acute myeloid leukemia) and one normal cell (human umbilical vein endothelial cells). RESULTS: Methanolic extract of leaves had the most potent antihyperlipidemic activity in P-407 model, whereby it significantly reduced serum levels of total cholesterol (P<0.01), triglycerides (P<0.01), low-density lipoprotein (P<0.05), verylow- density lipoprotein (P<0.01) and atherogenic index (P<0.01). On the other hand, methanolic extracts of A. carambola stem and leaves showed the strongest antioxidant activity. Total phenolic and flavonoid contents of the extracts exhibited significant correlations with antioxidant but not with antihyperlipidemic activities. All plant parts showed no cytotoxic effect on the selected cancer or normal cell lines. CONCLUSION: Antihyperlipidemic activity of different parts of A. carambola is greatly affected by extraction solvents used. Methanolic extract of A. carambola leaves exhibited higher antihyperlipidemic and antioxidant potentials compared to other parts of the plant.

FIKK kinases are a novel family of kinases unique to the Apicomplexa. While most apicomplexans encode a single FIKK kinase, Plasmodium falciparum expresses 21 and piroplasms do not encode a FIKK kinase. FIKK kinases share a conserved C-terminal catalytic domain, but the N-terminal region is highly variable and contains no known functional domains. To date, FIKK kinases have been primarily studied in P. falciparum and Plasmodium berghei. Those that have been studied are exported from the parasite and associate with diverse locations in the infected erythrocyte cytosol or membrane. Deletion of individual P. falciparum FIKK kinases indicates that they may play a role in modification of the infected erythrocyte. The current study characterises the single FIKK gene in Toxoplasma gondii to evaluate the importance of the FIKK kinase in an apicomplexan that has a single FIKK kinase. The TgFIKK gene encoded a protein of approximately 280kDa. Endogenous tagging of the FIKK protein with Yellow Fluorescent Protein showed that the FIKK protein exclusively localised to the posterior end of tachyzoites. A Yellow Fluorescent Protein-tagged FIKK and a Ty-tagged FIKK both co-localised with T. gondii membrane occupation and recognition nexus protein to the basal complex and were localised apical to inner membrane complex protein-5 and Centrin2. Deletion of TgFIKK, surprisingly, had no detectable effect on the parasite's lytic cycle in vitro in human fibroblast cells or in acute virulence in vivo. Thus, our results clearly show that while the FIKK kinase is expressed in tachyzoites, it is not essential for the lytic cycle of T. gondii.

HISTORY AND ADMISSION FINDINGS: A 62-year-old woman presented with history of repeat syncope and palpitations. She experienced aggravation of symptoms within the last few months. At referring hospital a ventricular tachycardia was already inducible during electrophysiological study. The patient was transferred to our hospital for VT ablation vs. ICD implantation. INVESTIGATION: No evidence for structural heart disease was revealed during TTE nor was a coronary heart disease detectable during coronary angiography, only hypertension was verifiable. No ICD implantation so far. TREATMENT AND COURSE: The patient underwent repeat EP study at our facility with induction of VT. Pace-mapping and mapping for earliest ventricular activation was performed. The middle-cardiac vein was revealed as site of earliest ventricular activation (50â ms) and good pace-map. Therefore, radiofrequency ablation at this site terminated successfully VT into sinus rhythm. CONCLUSION: Ablation of epicardial VT foci is successfully feasible via coronary sinus. With regard to typical ECG parameters an epicardial foci may be assumed precociously. The great cardiac vein is one of the most common sites of origin for epicardial foci, however, VT partially may originate from the crux cordis which is accessible for ablation via the middle cardiac vein with good ablation results.
