It used a set of policy and non-policy macroeconomic variables based on monthly data spanning the period 2007 and 2020. The structural impulse response functions provided evidence to support the use of the MPR as a signaling rate for domestic interest rates but was, however, found to be ineffective in stabilizing prices or increasing output. Furthermore, results from the variance decomposition of the non-policy variables found the effect of exchange rate innovations to be more significant in explaining variations in the price level. The study, therefore, concludes that the effectiveness of the policy rate in stabilizing prices is dampened by shocks prevalent from the external sector. Given the importance of international trade, the study recommends aggressive exchange rate manage...

The study employed Autoregressive Distributed Lagged (ARDL) model to establish both the long-run and short-run relationship between deficit financing and consumption. The study found no strong evidence to reject the Ricardian Equivalence using data from Nigeria economy contrary to most literatures reviewing RET in Nigeria. Specifically, the study found that deficit financing variables like debt, tax revenue, and government expenditure have significant impact on consumption when the strict assumption of RET is not introduced in the model but became insignificant when ratio of tax revenue to changes in debt is introduced in the model. The study therefore concludes that Ricardian Equivalence is valid in the case of Nigeria when strict assumption of RET is maintained but insignificant when the major assumption of RET is relaxed or when deficit finance variables e...

The oxidative and psychological stress cause physiological changes in the body. Shift in the methylation pathway, elevated cortisol, lowered neurotransmitter levels and lowered immune system allow infection to penetrate the body and lead to anxiety and depression. Here, a case report of a 20 year old male patient is presented to show how infectious skin lesions, unresponsive to the usual treatment plan, were treated after using a multipronged approach of addressing systemic infection of Escherichia coli, elevated cortisol levels and nutritional imbalances.

They are in the center of an anatomical area of the face very important for rejuvenation procedures, the so‐called “periorbital region.” The appearance of the eyes therefore decisively influences the perception of the aesthetics and aging of the entire face. In juvenile age, the skin of the periocular area is elastic and tonic, without sun damage; the eyebrow is full, well defined, and not descending; there is a clear and visible fold of the upper eyelid, with minimal dermatochalasis; the lower eyelid is tense and well positioned. The aim of this preliminary study is to define a protocol for the use of plasma technology in the treatment of aging signs of the periorbital region. The protocol is aimed to provide predictable, constant, and safe results.

Cigarette smoking is an important confounder in the relationship between ventilatory function indices and basic anthropometric parameters. Aim: To determine the relationship between anthropometric parameters and ventilatory function among male adult cigarette smokers. Materials and Methods: This is a community-based cross-sectional study incorporating 200 male participants (150 cigarette smokers and 50 non-smokers) who met inclusion criteria using stratified random sampling technique. Participants were drawn from local governments that constituted Sokoto metropolis. Subsequently, participants had a questionnaire adapted from European Community Respiratory Health Survey administered to collect demographic, clinical and cigarette smoking data. Ventilatory function test was performed using Clement Clarke One Flow Spirometer, version 1.3 Revision 0 (Clement Clarke International, Edinburgh, UK). The highest value of each ventilatory function indices (FEV1, FVC, FEV1/FVC) was chosen for analysis. Data were summarized, and statistical tests were applied using the software Statistical Package for Social Sciences, version 19 (IBM SPSS Inc., Chicago, IL, USA). Result: The majority of study participants among cigarette smokers and control were young, single and had a form of formal education. There was no significant difference in the mean of anthropometric indices [weight, height, body mass index (BMI)] of participants (cigarette smokers) and control (non-cigarette smokers). Twenty-nine (58%) non-cigarette smokers were overweight/obese as against 35 (23.3%) participants among cigarette smokers observed to be equally overweight/obese. Mean values of the ventilatory function indices except FVC were low among study participants as compared with control. Furthermore, the mean FEV1/FVC between participants (75.60 ± 7.53) and control (82.48 ± 6.11) was statistically significant (P = 0.001). A significant correlation between anthropometric parameters (height and BMI) and ventilatory function indices (FEV1 and FVC) was observed among study participants and control. Conclusion: Ventilatory function indices are associated with anthropometric parameters among cigarette smokers. Although, BMI did not significantly affect decline in ventilatory function indices among cigarette smokers, an inverse relationship was observed between them.

Electrical resistivity imaging (ERI) is a technique that has proven effective in detecting and mapping hidden mine workings. It is based on conceptual resistivity model that explores resistivity contrast between the subsurface voids and surrounding host materials and also characterizes the voids with higher or lower resistivity as either empty or in-filled voids than the host. The survey was carried out with Terrameter SAS 4000 and ES 464 electrode selector equipment adopting dipole-dipole electrode configuration at electrode spacing of 5 m to acquire data along three parallel profiles laid at equal interval 40 m in the study area. The acquired datas were processed and inverted with RES2DINV algorithm software. From the results, it shows air-filled cavities are found in the top-layers of e...

Timely and accurate diagnosis is pivotal to the reduction in tuberculosis related morbidity and mortality. In addition, drug resistant form of tuberculosis is a serious threat to the efforts at tuberculosis control and eradication. Hence; there is the need for efficient methods of Mycobacterium tuberculosis infection diagnosis and treatment. There are major advances in the laboratory diagnostic methods for detection of Mycobacterium tuberculosis which seeks to complement or replace the existing conventional methods in a view to reduction in under-diagnosis and improved infectious disease management. Chest computer tomographies, Cephid GeneXpert, Line probe are some of the Mycobacterium tuberculosis diagnostic advances while chest x-ray, sputum microscopy/culture represent some of the conventional methods of evaluation of both Mycobacterium tuberculosis infection and its m...
