Dietary supplementation with green tea extract promotes enhanced human leukocyte activity

Background: Leukocytes play a vital role in the host defence and inflammatory systems, the latter being responsible for the pathogenesis of a wide spectrum of acute and chronic diseases. Green tea is a popular beverage, which is consumed worldwide and its active ingredients are epicatechin derivatives, which possess distinct anti-inflammatory properties. The purpose of this study was to investigate if a green tea extract could enhance leukocyte function in humans. Methods: Volunteers were asked to take 300 mg of the green tea extract daily for 14 days and the capacity of circulating leukocytes to release both myeloperoxidase and lactoferrin was assessed. Whole blood from volunteers was stimulated with the bacterial peptide Formyl-Methionine-Leucine-Phenylalanine (fMet-Leu-Phe). Myeloperoxidase an enzyme that converts hydrogen peroxide to hypochlorous acid and is stored and secreted from the granules of neutrophils and monocytes and was measured as well as lactoferrin which is an iron-binding protein stored and secreted from the neutrophils. In conjunction the antioxidant capacity of the blood of the volunteers was also determined using a chemiluminescence method that measures the capacity of plasma to scavenge superoxide. Results: After 14 days of treatment there was a significant increase in the release of myeloperoxidase and lactoferrin when whole blood was stimulated with fMet-Leu-Phe (p<0.05), which activates a number of leukocytes including mature neutrophils and monocytes. This was mirrored by a significant increase in the total antioxidant status after 14 days of green tea ingestion (p0.05). After the “wash-out” period of 4 weeks, all parameters were consistent with those observed at the start of the trial (day 0). Treatment with the green tea extract also caused a slight but non-significant decrease in the number of circulating leukocytes, but the counts remained within published “normal” ranges for healthy human adults. Conclusions: This study indicates that a green tea extract when taken as a dietary supplement for 14 days can increase the leukocyte activity and the total plasma antioxidant status and may have role to play in the prevention of inflammatory disease

THE INFLUENCE OF VILLAGE POLICIES, COMMUNITY PARTICIPATION, CAPACITY OF BUMDES MANAGEMENT ON VILLAGE ECONOMIC DEVELOPMENT IN SOUTH AMFOANG DISTRICT

Village-owned enterprises (BUMDes) are village business institutions managed by the community and village government in an effort to strengthen the village economy and are formed based on the needs and potential of the village. In Kupang district, especially South Amfoang sub-district, which consists of 6 villages, there are several BUMDes programs implemented, namely savings and loans, village kiosks and cattle fattening. These villages are still lagging behind in terms of poor infrastructure, inadequate access to information, minimal human resources and population income that is still below average. This of course will affect the development of the village economy. This study aims to determine the description of village policy data. This study aims to determine the description of village policy data, community participation, and the capacity of BUMDes managers in the context of village economic development, to analyze the direct effect of village policies, community participation and the capacity of BUMDes managers on village economic development in South Amfoang sub-district. The method used in this research is quantitative research which is regressive in nature, namely research conducted to find the influence of policies, community participation and the capacity of BUMDes managers on economic development in 6 villages located in Amfoang Selatan sub-district, Kupang district.

Kyste neurentérique intra dural extra médullaire: à propos d’un cas

Le kyste neurentérique (KNE) est une malformation congénitale rare du système nerveux central (SNC) entrant dans le cadre des notochordodysraphies. Nous rapportons un nouveau cas de KNE de localisation intra durale extra médullaire chez un patient de 16 ans, admis dans un tableau de compression médullaire cervicale haut évoluant depuis 4 mois. L’imagerie a objectivé une lésion kystique pré médullaire en regardde C1-C2-C3. Le patient a bénéficié d’une évacuation kystique et l’histologie avait conclu à un kyste neurentérique. L’évolution était marquée par le décès du patient par des complications neurovégétatives graves. Malgré sa bénignité histologique, le kyste neurentérique de localisation cervicale haute peut se compliquer de troubles neurovégétatifs parfois imprévisibles pouvant aboutir à une évolution dramatique

Traitement peu invasif d’une breche osteo meningee associee a une hypertension intracranienne benigne

Description L’hypertension intracrânienne bénigne (HTICB) est une augmentation anormale de la pression intracrânienne non associée à un processus occupant de l’espace intracrânien, une thrombose des veinescérébrales ou une hydrocéphalie. Caractérisée par des céphalées invalidantes, des acouphènes pulsatiles, elle peut avoir une évolution péjorative et irréversible entraînant une cécité. La survenue d’une rhinorrhée spontanée dans un contexte d’HTICB a été décrite dans la littérature mais demeure peu fréquente. Objectif et cas cliniqueNous rapportons le cas d’une femme obèse âgée de 40 ans, qui a été admise pour rhinorrhée droite spontanée. Les explorations neuroradiologiques ont permis d’évoquer une hypertension intracrânienne bénigne sur une brèche ethmoïdale antérieure. Le monitoring de la pression a confirmé le diagnostic. Elle abénéficié d’une dérivation ventriculo péritonéale. L’évolution est favorable (disparition des symptômes) avec un delai de recul de 16 mois . Conclusion L’HTICB est une pathologie avec des conséquences irréversibles si le traitement n’est pas adéquat et rapide. En cas de rhinorrhée isolée dans le cadre de l’hypertension intracrânienne bénigne la dérivation ventriculo péritonéale est une attitude thérapeutique simple mais efficace

Climate Change and Potential Environmental Hazards with Perspective Adaptation Technologies in Nigeria, A review

Abstract. Climate change is a global phenomenon with multifarious unique regional consequences. Contemporary studies have established Climate change as a product of anthropogenic activities. Studies have linked extreme weather events, heat waves, increase pollution, crop failure as some of the many discernable effects of climate change. Hence, the spatial temporal effects of Climate change are of concern to policy makers, researchers, innovators and the entire public to develop veritable mitigation strategies. This paper examines climate change in Nigeria as a case study; the research adopted desk research method to collect secondary data from literature about hazards caused by climate change and potential adaptation strategies in Nigeria. The findings revealed that a potential environmental hazard caused by climate change in Nigeria includes that of biological, chemical, physical, mechanical and psycho-social. Moreover, this review further showed adaptation technologies that can be used in adapting and mitigating climate change in Nigeria

GLIOBLASTOME MULTIFORME INTRAVENTRICULAIRE : A PROPOS D’UN CAS ET REVUE DE LA LITTERATURE

Les glioblastomes (GBM) multiformes représentent 15-20% des tumeurs cérébrales. Ils sont plus fréquents chez les sujets âgés et sont le plus souvent localisés au niveau des lobes frontal et temporal. Leur localisation intraventriculaire est rare. Nous rapportons le cas d’une femme de 44 ans qui présente des signes d’hypertension intracrânienne et de trouble de la mémoire. L’imagerie cérébrale (TDM et IRM) retrouve deux lésions hétérogènes, à contours irréguliers et prenant le contraste de façon hétérogène associées à une hydrocéphalie. Elles se sont développées aux dépens de 2 cornes frontales et du corps des ventricules latéraux. Après une dérivation ventriculo-péritonéale et une biopsie stéréotaxique, l’histologie confirme le diagnostic de GBM multiforme. Nous rapportons cette observation avec une revue de la littérature tout en insistant sur l’aspect pathogénique

The crossroads of tradition and modern technology: integrative approaches to studying carnivores in low density ecosystems

The study of large carnivores in semi-arid ecosystems presents inherent challenges due to their low densities, extensive home ranges, and elusive nature. We explore the potential for the synthesis of traditional knowledge (i.e. art of tracking) and modern technology to address challenges in conservation and wildlife research in these challenging environments. Our research focuses on the African lion (Panthera leo) in the Central Kalahari region of Botswana as a model system to demonstrate the potential of this integrative approach. Combining GPS tracking and traditional San trackers’ expertise, we present two case studies: (1) the individual identification of lions via a combination of tracking and footprint analysis and (2) the monitoring of territorial behavior through a combination of GPS technology (i.e. GPS collars and handheld GPS devices) and non-invasive tracking. These approaches enhance our understanding of carnivore ecology as well as support conservation efforts by offering a non-invasive, cost-effective, and highly accurate means of monitoring populations. Our findings underscore the value of merging traditional tracking skills with contemporary analytical and technological developments to offer new insights into the ecology of carnivores in challenging environments. This approach not only improves data collection accuracy and efficiency but also fosters a deeper understanding of wildlife, ensuring the conservation and sustainable management of these species. Our work advocates for the inclusion of indigenous knowledge in conservation science, highlighting its relevance and applicability across various disciplines, thereby broadening the methodologies used to study wildlife, monitor populations, and inform conservation strategies

19q13.11 cryptic deletion : description of two new cases and indication for a role of WTIP haploinsufficiency in hypospadias

Developmental delay/intellectual disabilities, speech disturbance, pre- and postnatal growth retardation, microcephaly, signs of ectodermal dysplasia, and genital malformations in males (hypospadias) represent the phenotypic core of the recent emerging 19q13.11 deletion syndrome. Using array-CGH for genome-wide screening we detected an interstitial deletion of chromosome band 19q13.11 in two patients exhibiting the recognizable pattern of malformations as described in other instances of this submicroscopic genomic imbalance. The deletion detected in our patients has been compared with previously reported cases leading to the refinement of the minimal overlapping region (MOR) for this microdeletion syndrome to 324 kb. This region encompasses five genes: four zinc finger (ZNF) genes belonging to the KRAB-ZNF subfamily (ZNF302, ZNF181, ZNF599, and ZNF30) and LOC400685. On the basis of our male patient 1 and on further six male cases of the literature, we also highlighted that larger 19q13.11 deletions including the Wilms tumor interacting protein (WTIP) gene, proximal to the MOR, results in hypospadias making this gene a possible candidate for this genital abnormality due to its well-known interaction with WT1. Although the mechanism underlying the phenotypic effects of copy number alterations involving KRAB-ZNF genes at 19q13.11 has not clearly been established, we suggest their haploinsufficiency as the most likely candidate for the phenotypic core of the 19q13.11 deletion syndrome. In addition, we hypothesized WTIP gene haploinsufficiency as responsible for hypospadias
