Assessing Tuberculosis and Risk Factors: Population Study in Rivers State, Nigeria's Niger Delta Region, Nigeria
Authors: Nwalozie Rhoda , Nnokam Brenda Anyakwe , Kareem Jubril Adeyinka , Obi-Thomas Jane Nkechi 
Published: April 2024

Mycobacterium tuberculosis (MTB), an infectious airborne bacterium primarily impacting the lungs and instigating a chronic inflammatory response, persists as an enduring menace. This study aims to evaluate the interplay between MTB infection and associated risk factors in Rivers State, Nigeria. The study involved 392 participants from three local government areas (LGAs): Eleme, Obio/Akpor, and PHALGA. Data collection involved a structured questionnaire covering socio-demographics variables and associated risk factors. A stratified random sampling method was employed. Statistical analysis, including descriptive statistics and Spearman's correlation coefficient, was performed using SPSS version 25. Correlation analysis of socio-demographic variables revealed no significant associations with MTB, as indicated by non-significant p-values of (p=0.27), (p=0.83), (p=0.42), (p=0.35), (p=0.49), (p=0.28) for age, sex, education, occupation, marital status and geographical area respectively. However, significant positive weak correlations emerged between MTB infection and cough (p=0.00), hepatitis (p=0.01), coughing blood (p=0.00), and fever (p=0.00). Conversely, family TB history (p=0.93), cough lasting 2 weeks (p=0.84), weight loss (p=0.19), contact with a person who has been coughing for 2 weeks (p=0.93), and alcohol consumption (p=0.55) did not show significant associations. While demographic characteristics alone may not be strong predictors of MTB infection, this study highlights the complex interplay between various risk factors Addressing these risk factors through targeted interventions and raising awareness can contribute to reducing the TB burden in Rivers State and the Niger Delta region.
Evaluation of the Effects of Different Sowing and Weed Control Methods on the Physiological Performance of NERICA 4 Rice Variety in Upland Ecology of Japan
Authors: Mumeen A.Y. , Sulemana A. , Urayama H. 
Published: April 2024

The experiment was established to determine the most yield enhancing combination of sowing method and weed control measure for the selected rice variety- NERICA 4. The experiment was conducted from March to November 2023, at the upland research field of JICA’s Tsukuba International Center (TBIC), Japan. The experiment forms part of the fulfilment for the completion of a rice research technique fellowship in the Knowledge Co-Creation Program (KCCP) organized and funded by the Japan International Cooperation Agency (JICA). It consists of two sowing methods; Drilling (S1) and Dibling (S2)) as well as three methods of weed control; Chemical Weeding only at Sowing (CW), Chemical Weeding at sowing with once Hand Weeding at 60 DAS (CWHW) and Chemical Weeding at Sowing with Twice Hand Weeding at 60 and 90 DAS (CW2HW) which were combined to form six treatments. Treatments were laid in Randomized Complete Block Design (RCBD) with three replications of eighteen (18) plots. 8.9 g/plot of pendimethalin 2% (G0-G0-SAN) was used. Amaranthaceae, Cyperaceae and Poaceae were the prevalence weeds family identified. The treatment assigned to drilling and twice hand weeding in addition to chemical weeding at sowing (S1CW2HW) had the highest yield (3.95 tons/ha) while the treatment assigned to dibbling with the weeding control plot of only chemical weeding at sowing (S2CW) gave the lowest yield (2.5 tons/ha). There was significant difference at (P<0.05) amongst the mean yield values of all treatment combinations. However, the treatment assigned to same drilling but with once hand weeding (S1CWHW) had the highest profitability rank. This study concludes that sowing with drilling and weed management by pendimethalin and once hand weeding may be productively viable for the variety. This outcome may serve as a benchmark for further research within same thematic framework for increased productivity of rice farmers in the west African sub-region from where the first two authors were sent for the experiment in Japan.

Published: June 2008

AbstractWe report on two new patients with straight‐chain acyl‐coenzyme A oxidase deficiency. Early onset hypotonia, seizures and psychomotor delay were observed in both cases. Plasma very‐long‐chain fatty acids were abnormal in both patients, whereas the plasma levels of phytanic acid, pristanic acid, the bile acid intermediates DHCA and THCA, and erythrocyte plasmalogen levels were normal. Studies in fibroblasts from the two patients revealed a deficiency of one of the two peroxisomal acyl‐CoA oxidases, that is, straight‐chain acyl‐CoA oxidase (ACOX1). Subsequent molecular analysis of ACOX1 showed a homozygous deletion, which removes a large part of intron 3 and exons 4–14 in the first patient. Mutation analysis in the second patient revealed compound heterozygosity for two mutations, including: (1) a c.692 G > T (p.G231V) mutation and (2) skipping of exon 13 (c.1729_1935del (p.G577_E645del). © 2008 Wiley‐Liss, Inc.
Vertebral Pathology in an Ornithopod Dinosaur: A Hemivertebra in Dysalotosaurus lettowvorbecki from the Jurassic of Tanzania
Authors: Witzmann Florian , Asbach Patrick , Remes Kristian , Hampe Oliver , Hilger André , Paulke Andreas 
Published: June 2008

AbstractA vertebral fragment of the Late Jurassic ornithopod dinosaur Dysalotosaurus lettowvorbecki from Tanzania is described. It consists of a hemivertebra that is co‐ossified with a complete vertebral centrum. The hemivertebra causes a hyperkyphotic posture of the vertebral column with an angle of approximately 35° between the end plates of the vertebra, that is, a dorsal bending of the vertebral column. Associated with this is a 15° lateral bending, which suggests a scoliosis. Micro‐CT scans reveal thickening of the cortical bone in the hemivertebra and the complete vertebral centrum as compared to a “normal” vertebra. This can be interpreted as a reaction of the bone to the abnormal direction of forces arising from the defective configuration of the vertebral column. No signs of vertebral fracture are present. The arrangement of the Foramina venosa and the trapezoidal outline of the complete centrum that is co‐ossified with the hemivertebra indicate that the hemivertebra in Dysalotosaurus developed early in embryogenesis probably by “hemimetameric segmental shift”, that is, a defect of the fusion of the paired vertebral anlagen. This finding illustrates that hemivertebrae represent a fundamental defect of the vertebrate ontogenetic program. Anat Rec, 291:1149‐1155, 2008. © 2008 Wiley‐Liss, Inc.
Genome‐scale model for Clostridium acetobutylicum: Part I. Metabolic network resolution and analysis
Authors: Senger Ryan S. , Papoutsakis Eleftherios T. 
Published: June 2008

AbstractA genome‐scale metabolic network reconstruction for Clostridium acetobutylicum (ATCC 824) was carried out using a new semi‐automated reverse engineering algorithm. The network consists of 422 intracellular metabolites involved in 552 reactions and includes 80 membrane transport reactions. The metabolic network illustrates the reliance of clostridia on the urea cycle, intracellular L‐glutamate solute pools, and the acetylornithine transaminase for amino acid biosynthesis from the 2‐oxoglutarate precursor. The semi‐automated reverse engineering algorithm identified discrepancies in reaction network databases that are major obstacles for fully automated network‐building algorithms. The proposed semi‐automated approach allowed for the conservation of unique clostridial metabolic pathways, such as an incomplete TCA cycle. A thermodynamic analysis was used to determine the physiological conditions under which proposed pathways (e.g., reverse partial TCA cycle and reverse arginine biosynthesis pathway) are feasible. The reconstructed metabolic network was used to create a genome‐scale model that correctly characterized the butyrate kinase knock‐out and the asolventogenic M5 pSOL1 megaplasmid degenerate strains. Systematic gene knock‐out simulations were performed to identify a set of genes encoding clostridial enzymes essential for growth in silico. Biotechnol. Bioeng. © 2008 Wiley Periodicals, Inc.
