Self-reported psychological distress and its relationship with religiousness of Nigerian physicians: A multicenter study
Physicians are prone to psychological distress, and this has been poorly studied in association with religiousness. As a result, the prevalence of psychological distress among physicians and its relationship with religiousness was investigated. The study was conducted at two neuropsychiatric centers, and two teaching hospitals in the South-South and South-West regions of Nigeria. Demographics and practice-related characteristics of 231 physicians were collected in addition to report on psychological distress using the 12-item General Health Questionnaire, and a religiousness measuring scale, Ironson–Woods Spirituality/Religiosity Index. Chi-square and t-test analyses were done using SPSS version 19. The prevalence rate of significant psychological distress among physicians was 19.05%. The physicians’ specialty of practice fell short of statistically significant association with religiousness (X2=9.02, p=0.06). There was no significant association between physicians’ state of health and religiousness. Psychological distress is fairly common among physicians and shows no relationship with religiousness
Assessment of Ecological Status and Tree Diversity in Watershed Area of Dandi Local Government Area in Kebbi State, Nigeria
This study assessed the ecological and tree diversity status of watershed area of Dandi local government area in Kebbi state using systematic sampling technique. Three transects of 300 m long were laid at 100 m intervals. On each transect, six sample plots of size 50 m x 50 m (0.25ha) were alternately laid at 50 m intervals. A total of 18 sample plots will be used for the study. Diameters at breast height (Dbh) of all the trees found in the plot with Dbh ≥ 5cm will be measured. Fourteen tree species belonging to 10 genera and 8 families were identified. Borassus aethiopum of the family Arecaceae was the most abundant species in the area with a relative density (RD) and diversity index (DI) of 0.296 and 0.08728 respectively. This was followed by Cocos nucifera in the Arecaceae family also, with RD and DI of 0.192 and 0.03662 respectively. Daniella oliveri of the family Fabaceae was the least represented species with RD and DI of 0.0018 and 0.00002 respectively. The overall tree species richness in the area was 0.0052
African Polyherbal Formulation Possesses Chemopreventive and Chemotherapeutic Effects on Benzene - Induced Leu kemia in Wistar Rats
Chemotherapy and radiotherapy are effective cancer treatment options but they are
accompanied by serious side effects and complications such as systemic cytotoxicity, chemo
-
or
radio
-
resistance. Therefore, more effective therapies are sorely
needed. This study investigated the
chemopreventive and chemotherapeutic effects of a polyherbal formulation on benzene
induced eukemia in Wistar rats. The polyherbal formulation is composed of fruits such as Orange, Lime,
Lemon, Pineapple, Grape and Vege
tables like; Pumpkin leave, Garden egg suspended in honey
medium.
Method
s
:
Leukemia was induced by injecting 0.2 ml of benzene solution intravenously through the
tail of young rats at 48 h intervals for four times. Leukemia developed in 92% of rats some w
eeks
after the last benzene injection and following up weekly observation for leukemia development in
appropriate rat groups. Leukemia burden was assessed using indicator parameters such as total
leukocyte, red blood cell count, hematocrit, and hemoglobin
concentration. Exactly 0.48 ml of the
polyherbal formulation was administered orally by gavage using oral cannular once daily post
leukemia induction for four weeks.
Results:
Leukemia induction reflected in significant reduction in hematocrit, hemoglobin
concentration, red cell count and a marked and a significant increase in leukocyte count over the
control (p < 0.05). There is significant difference between the chemopreventive group and
chemotherapeutic (leukemia positive group treated with poly
-
herbal f
ormulation) and the leukemia
positive control group untreated.
Conclusion:
This study reveals profound activity of the poly
-
herbal formulation at preventing and
reversing experimentally developed leukemia in the rat groups, hence the ability of the polyhe

Unit root modeling for trending stock market series
In this paper, we examine how the unit root for stock market series should be modeled. We employ the Narayan and Liu (2015) trend GARCH-based unit root and its variants in order to more carefully capture the inherent statistical behavior of the series. We utilize daily, weekly and monthly data covering nineteen countries across the regions of America, Asia and Europe. We find that the nature of data frequency matters for unit root testing when dealing with stock market data. Our evidence also suggests that stock market data is better modeled in the presence of structural breaks, conditional heteroscedasticity and time trend

Determination of Water Consumption Rate for A Growing Urban City in Osun State, Nigeria
Water is the simplest important element of life that is basic to manrsquos existence. Most researchers are discouragedfrom working on determination of water consumption rate in Ikirun due to improper and inadequatewater demand data estimate in Ikirun the headquarters of Ifelodun local government in Osun State. Hence, this study determines the rate of water consumption in Ikirun.1213 questionnaires related to water uses and demand rate were randomly distributed to residential, and 250 were administered on institutional, commercial and industrial consumers from high density area (Eweta), medium density area (Oja-Oba, Thursday market, Oke-Afo area) and low density area (Laade/testing ground area) using End Use Analysis Technique.The results obtained show that most residential and commercial consumers source water from deep well, industrial consumers source their water from boreholes while institutional consumers mostly depend on tap water for their basic needs. The total volume of water used daily per house for residential consumers at low density area varied from 95-1255liters, the values at medium density area varied from 3465-11,570liters, while that of high density area varied from 3485-22,805liters. The daily values for total volume of water consumed for commercial, industrial and institutional facilities were4,824, 3299 and 3812 liters respectively. The average water demand for low, medium and high density areas were 25.31 l/c/day, 16.42 l/c/day, and 27.61 l/c/day which is not within the range specified by WHO standard. It is recommended that the water pipe network should be extended to all nook and cranes of Ikirun township to allow consumers access to portable water.nbs
Cooling potential of formulated bio-quenchant oils on cast Aluminium alloy material
The biodegradable vegetable oil based quenchants can serve as cooling media alternative to that of the toxic non-biodegradable petroleum based mineral oil in a heat treatment of aluminium and its alloy. 70 vol. % of edible vegetable oil are blended with 30 vol. % of Jatropha oil to form bio-quenchant oils for Aluminium (Al)-alloy probe treated at 500oC and soaked for 15 min in a mue furnace. The cooling potential properties such as the cooling rate, the heat transfer coecient, the Grossman quench severity and the biot number are investigated. The results obtained show that the blended bleached (BB) melon oil provides the highest cooling rate of 49.30oC s-1, while the blended raw (BR) palm oil ensures the lowest cooling rate of 18.45oCs-1. Heat transfer coecients of 704.6 Wm-2K-1, 432.3 Wm-2K-1, and 394.4 Wm-2K-1 are exhibited by the blended bleached melon oil, the blended raw melon oil and the blended bleached groundnut oil, respectively. They are found higher than that of a petroleum based mineral oil, which amounts to 68.7 Wm-2K-1. The lowest heat transfer coecient of 272.11 Wm-2K-1 is obtained in case of using a blended raw palm oil. The quench severity of the blended bleached melon oil, the blended raw melon oil and the blended raw groundnut oil refers to a Grossman H-factor of 1.01 m-1, 0.78 m-1, and 0.67 m-1, respectively. The lat-ter values are higher than that obtained in case of a blended raw palm oil, which is equal to 0.37 m-1. However, the heat ow parameters obtained reveal that the blended bleached and the blended raw melon and groundnut oil can be characterized as fast quenching oils, while the blended bleached and the blended raw palm oil can be characterized as medium quenching oils of results comparable to and even better than those of the industrial petroleum based mineral oil
Anevrisme mycotique tuberculeux de la carotide commune gauche au Benin
L’anévrisme mycotique tuberculeux est très rare et n’a jamais été décrit comme une atteinte extra pulmonaire de la tuberculose au Bénin. Nous rapportons ici le cas d’une jeune femme de 25 ans présentant des conglomérats d’adénopathies cervicales chez qui le diagnostic de tuberculose ganglionnaire été posée par l’anatomopathologie.L’apparition trois mois après le début de la symptomatologie d’une masse latéro cervicale gauche pulsatile et rapidement progressive a motivé la réalisation d’une échographie doppler cervicale puis celle d’un angioscanner des troncs supra aortiques qui ont conclu à un pseudo anévrisme mycotique de la carotide commune gauche.L’anévrisme mycotique tuberculeux carotidien est rare. L’échographie doppler des vaisseaux du cou et l’angioscanner des troncs supra aortiques constituent la pierre angulaire du diagnostic des anévrismes infectieux.Mots clés: Anévrisme mycotique, Tuberculose, Echo doppler, Angioscanner, BéninEnglish Title: Tuberculous mycotic aneurysm of the left common carotid artery, Benin, West AfricaEnglish AbstractMycotic tuberculous aneurysm is very rare and has never been described as extrapulmonary tuberculosis in Benin country. We report the case of a 25-year-old woman with conglomerates of cervical lymphadenopathy diagnosed with lymph node tuberculosis by anatomopathology. The appearance of a pulsatile and rapidly progressive left lateral cervical mass three months after the beginning of the symptomatology motivated a cervical doppler ultrasound and a CT angiography of supra aortic trunks help to diagnose a pseudo mycotic aneurysm of the left common carotid.Mycotic carotid tubercle aneurysm is a rare disease. Doppler ultrasound of the vessels of the neck and CT angiography of supra aortic trunks are the cornerstone of the diagnosis of infectious aneurysms.Keywords: Mycotic aneurysm, Tuberculosis, Doppler ultrasonography, CT angiography, Beni
