Objective:This study was undertaken to determine the likelihood of having serum total prostate specific antigen(PSA)levels ≥4.0 ng/mL and ≥10.0 ng/mL among a cohort of non-obese and obese Nigerian men with lower urinary tract symptoms(LUTS).Methods:This was a prospective cross-sectional survey among men who presented with benign prostatic hypertrophy to the urology clinic of the Ekiti State University Teaching Hospital,Ado-Ekiti with LUTS between January 1 and December 31,*** hundred and forty men who presented in the urologic clinic with LUTS were *** was analyzed using standard method while other clinical variables were collected using a clinical case *** logistic regression was used to estimate the odds of an abnormal PSA of ≥4.0 ng/mL or10.0 ng/mL in these ***:The mean ages of obese and non-obese men were 64.8 and 64.0 years *** mean total serum PSA were 14.8 and 13.2 ng/mL for obese and non-obese men *** analysis showed no difference(p>0.05)in the proportion of obese and non-obese men with LUTS who had a PSA threshold of at least 4.0 ng/*** logistic regression showed that,at a PSA threshold of 10.0 ng/mL,obese men had a statistically significant proportion(p<0.05).Although not significant,non-obese patients were less likely to have PSA level of ≥4.0 ng/mL(OR 0.701;95%CI 0.301e1.630)compared to obese *** same vein,non-obese men were less likely to have a PSA level of 10.0 ng/mL(OR,0.686;95%CI,0.318e1.478)in a simultaneous context of ***:Our study demonstrated that,in a sample population of predominantly native African men,there was a non-significantly higher likelihood of overweight/obese patients having a higher serum PSA level than the non-obese.A community based study is needed to further confirm this finding.

This paper examines automatic recognition and extraction of tables from a large collection of het-erogeneous documents. The heterogeneous documents are initially pre-processed and converted to HTML codes, after which an algorithm recognises the table portion of the documents. Hidden Markov Model (HMM) is then applied to the HTML code in order to extract the tables. The model was trained and tested with five hundred and twenty six self-generated tables (three hundred and twenty-one (321) tables for training and two hundred and five (205) tables for testing). Viterbi algorithm was implemented for the testing part. The system was evaluated in terms of accuracy, precision, recall and f-measure. The overall evaluation results show 88.8% accuracy, 96.8% precision, 91.7% recall and 88.8% F-measure revealing that the method is good at solving the problem of table extraction.

Cement-bonded particleboards of 6 mm in thickness were manufactured using maize stalk （Zea mays） particles of uniform sizes at three levels of board density and additive concentrations respectively. The bending strength and dimensional properties were assessed. Increase in board density and additive concentration caused increase in Modulus of rupture （MOR）, Modulus of elasticity （MOE）, and decrease in Thickness swelling （TS） and Water absorption （WA）. The MOR, MOE and TS of the boards were significantly affected by board density except for WA, but additive concentration affected all the boards＇ properties examined at p ≥ 0.05. Strong and dimensional stable cement-bonded boards could be manufactured from maize stalk particles with Portland cement as the binder after hot water treatment. Although the dimensional stability and mechanical strength properties of the boards were affected by the board density and additive concentration, the study revealed that cement-bonded particleboards could be manufactured from maize stalk （Zea mays） particles. However, the increase in board density and additive concentration could cause the increase in MOR and MOE, and cause the decrease in TS and WA of boards.

The Dirac equation is solved to obtain its approximate bound states for a spin-1/2 particle in the presence of trigonometric Poeschl-Teller （tPT） potential including a Coulomb-like tensor interaction with arbitrary spin-orbit quantum number κ using an approximation scheme to substitute the centrifugal terms κ（κ± i 1）r^-2. In view of spin and pseudo-spin （p-spin） symmetries, the relativistic energy eigenvalues and the corresponding two-component wave functions of a particle moving in the field of attractive and repulsive tPT potentials are obtained using the asymptotic iteration method （AIM）. We present numerical results in the absence and presence of tensor coupling A and for various values of spin and p-spin constants and quantum numbers n and κ. The non-relativistic limit is also obtained.

In the Peninsular Malaysia and Northern Borneo island of Malaysia, various rich indigenous leafy vegetables and fruits grow and contribute to the nutritional and dietary values of the population. They have high water contents, thus, naturally vulnerable to rapid food spoilage. Food preservation and processing play a vital role in the inhibition of food pathogens in fruits and vegetables that are prevalent in Malaysia. Lactic acid fermentation is generally a local-based bioprocess, among the oldest form and well-known for food-processing techniques among indigenous people there. The long shelf life of fermented vegetables and fruits improves their nutritional values and antioxidant potentials. Fermented leaves and vegetables can be utilized as a potential source of probiotics as they are host for several lactic acid bacteria such as Lactobacillus confusus, Weissella paramesenteroides, Enterococcus faecalis, Lactobacillus plantarum, Lactobacillus buchneri, Lactobacillus paracasei, Lactobacillus pentosus, Pediococcus acidilactici, Pediococcus pentosaceus and Leuconostoc mesenteroides. These strains may be more viable in metabolic systems whereby they can contribute to a substantial increase in essential biologically active element than industrial starter cultures. This review is aimed to address some essential fermented fruits and vegetables in Malaysia and their remarkable reputations as a potential sources of natural probiotics.
