Cor triatriatum sinistrium in a 10 year old Nigerian: A case report

We present a rare and first case of Cor triatriatum sinistrum (CT) in a patient who presents with dyspnoea, easy fatigability, chest pain, murmurs and typical ECG and 2D-echo findings. The purpose of presenting this casereport is to highlight the distinctive manifestation of Cor triatriatumsinistrum and to provide a concise report of this disease with the hopethat such information will help identify patients earlier in the course of their disease. Surgical correction offers good and long term results for both classicand atypical types. In a resource poor country like ours, high index of suspicion, early diagnosis and timely referral are warranted so as to avert death

Inter-Horizon Variability in Phosphorus-Sorption

Abstract: This study estimated the variability of phosphorus sorption capacity among horizons of highly weathered soils of Otammiri River floodplain in southeastern Nigeria. Four profile pits representing 4 depositional stages of the river were studied. The soils were deep, sandy, acidic and of low cation exchange capacity. Total carbon (organic matter) decreased with depth. Soils were classified as Isohyperthemic Arenic Paleadults. The values of phosphorus-sorption maximum (Smax) ranged from 48.0-83.0 mg kg -1 . Total carbon had highest influence on the P-sorption characteristics of epipedal horizons (Ap) while Fe M3 and Al M3 controlled P-sorption capacity in the sub-surface horizons (AB -Bt). Variability among horizons were distributed as follows: Ap (CV = 35%), AB (CV = 25%), Bt 1 (CV = 10%) and Bt 2 (CV = 8%)

Towards Improved Use of Vaccination in the Control of Infectious Bronchitis and Newcastle Disease in Poultry: Understanding the Immunological Mechanisms

Infectious bronchitis (IB) and Newcastle disease (ND) are two important diseases of poultry and have remained a threat to the development of the poultry industry in many parts of the world. The immunology of avian has been well studied and numerous vaccines have been developed against the two viruses. Most of these vaccines are either inactivated vaccines or live attenuated vaccines. Inactivated vaccines induce weak cellular immune responses and require priming with live or other types of vaccines. Advanced technology has been used to produce several types of vaccines that can initiate prime immune responses. However, as a result of rapid genetic variations, the control of these two viral infections through vaccination has remained a challenge. Using various strategies such as combination of live attenuated and inactivated vaccines, development of IB/ND vaccines, use of DNA vaccines and transgenic plant vaccines, the problem is being surmounted. It is hoped that with increasing understanding of the immunological mechanisms in birds that are used in fighting these viruses, a more successful control of the diseases will be achieved. This will go a long way in contributing to global food security and the economic development of many developing countries, given the role of poultry in the attainment of these goals
