Clinical predictive significance of biomarker molecules elevation during the transition period in in cattle suffering from different pathological states: A review
Authors: Tharwat Mohamed , Alkhedhairi Saleh , Asil El
Published: July 2024

The transition period (TP), which extends from 3 weeks prior to 3 weeks post parturition, is a critical period regarding the health, productivity, and profitability of dairy animals, during which most health disorders arise, include lameness, mastitis, rumen acidosis, ketosis, hypocalcemia (milk fever), left-displaced abomasum, fatty liver, hypophosphatemia and post-parturient hemoglobinuria, subacute ruminal acidosis, retained placenta, and metritis. Biomarkers are biological molecules distributed in blood, body fluids or tissues that represent physiological or pathophysiological indicators of events, processes, or conditions happening within the animal’s body. In the field of veterinary medicine, biomarkers are thought to have enormous valuable potentials in the field of clinical diagnosis, therapeutical research, surgery and obstetrical outcome. This review article aims to explore the significance of biomarkers used to predict pathological conditions and health status of cattle during the TP to facilitate the early clinical diagnosis and prompt treatment of TP-related diseases/or conditions and thus improve animal welfare, health and increase productivity.

Authors: Elgaffry Omnia , Darwish Wageh , Bayoumi Rasha , Hussein Mohamed , Megahed Ayman , Reda Lamiaa , Basiony Asmaa , Dawod Yomna
Published: July 2024

Background:
Meat products are widely recognized as substantial sources of protein derived from animals. Biogenic amines (BAs), naturally occurring toxins, are generated via the metabolism of specific amino acids by a vast array of microorganisms, including pathogenic and nonpathogenic strains.
Aim:
The aim of this study was to ascertain the quantity of BAs produced in five meat products that are commercially available in Egypt. Additionally, the estimated daily BA intakes of the Egyptian populace as a result of consuming these animal products were computed. Additionally, a study was undertaken to investigate the relationship between total biogenic amines (TBAs) and microbial counts, specifically total bacterial counts (TBC), total psychrophilic counts (TPsC), total Staphylococcus aureus (TSC), and total Enterobacteriaceae count (TEC) as they pertained to the meat products under investigation.
Methods:
One hundred samples of meat products (n = 20 for each) were selected at random from Egyptian markets. The collected samples included minced meat, luncheon, sausage, pasterma, and canned meat. The microbiological status and biogenic amine content of these samples were evaluated.
Results:
Total biogenic amines were calculated for the examined samples an beef mince had the highest TBA content at 918.22 ± 21.3 mg/Kg followed by sausage at 575.1 ± 12.8 mg/Kg, luncheon at 567.1 ± 17.8 mg/Kg, pasterma at 417.0 ± 31.8 mg/Kg, and canned meat at 242.8 ± 21.8 mg/Kg. The calculated EDI values for TBA ranged between 21.24 in canned meat to 80.34 in beef mince. It was determined that beef mince had the highest microbial contamination rates as indicated by the high TBC, TPsC, TSC, and TEC at 5.69 ± 0.4, 4.2 ± 0.5, 2.4 ± 0.2 and 4.69 ± 0.1 log 10 cfu/g. Such counts were 3.6 ± 0.2, 2.4 ± 0.2, 1.2 ± 0.1, and 4.3± 0.2 log 10 cfu/g in sausage, 3.4 ± 0.3, 2.2 ± 0.1, 1.1 ± 0.1, and 4.0 ± 0.1 log 10 cfu/g in luncheon, 2.5 ± 0.1, 1.0 ± 0.1, 1.4 ± 0.08 and 2.69 ± 0.2 log 10 cfu/g in pasterma; while none of the examined canned meat harbored microbial contamination
Conclusion:
This study indicated the presence of several BAs in meat products sold in Egypt. According to the EDI values of the examined BAs, the consumption of meat products by the Egyptian populace did not pose a risk. However, it is imperative that the handling, storage, distribution, and promotion of meat products conform to sanitary protocols.

Este artículo aborda la cuestión del abuso narcisista dentro de las relaciones de pareja en la que uno de los dos integrantes es psicópata integrado. Concretamente buscamos explicar en qué consiste y cuáles son las características de tal abuso, para después plasmar cuales son las consecuencias del mismo. En un primer momento explicamos qué es la psicopatía y en un segundo momento explicamos detalladamente que es el abuso narcisista y cuáles son sus fases (Bombardeo de amor, devaluación, descarte y hoovering) Para la consecución de nuestro objetivo, se expone el análisis de entrevistas a veinte mujeres que declaran haber estado en pareja con un psicópata integrado. Como instrumento metodológico para llevar a cabo el análisis de datos hemos empleado la Teoría Fundamentada, dado que partimos del análisis del discurso de las mujeres para generar teoría y no de hipótesis previas. Algunas de las conclusiones obtenidas tienen que ver con el establecimiento de un, hasta ahora desconocido, patrón de violencia y maltrato vinculado a la psicopatía y al narcisismo. Maltrato que deriva en un alto impacto emocional que tienen este tipo de relaciones de abuso en las parejas y ex parejas de psicópatas narcisistas.

Published: July 2024

The convergence of technology and digital communications has revolutionized most businesses, including education and training facilities. Advances in technology has completely transformed the world of work. Being well-educated is no longer sufficient. What matters is the possession of critical essential talents, skill sets, and capabilities. South Africa is characterised by high inequality, poverty and high unemployment. Thus, provision of quality education is one of strategies that could be employed to address such developmental challenges. Hence, the objective of this study was to assess teacher-lecturer competency in Science, Technology, Engineering, Arts, and Mathematics (STEAM) in KwaZulu-Natal. This study was conducted in different parts of KwaZulu-Natal province with participants from various schools and institutions of higher learning. The study was commissioned due to skills deficit that is perpetrated by, amongst other things, the poorly functioning basic education system, inadequate infrastructure, shortage of STEAM teacher supply, and skills mismatch. The study employed an exploratory research design, and the survey was used as the research strategy. Among other findings, the study found that while a significant portion of educators expressed a commitment to promoting reflective and critical thinking among learners and students, inadequate STEAM equipment and infrastructure continued to be the primary challenge in implementing STEAM. Furthermore, the study found that there is a majority support for the STEAM centres which suggests a positive inclination towards their establishment, underlining the perceived value they could bring to the educational landscape for both teachers and students. This study recommends a targeted professional development programs for educators at primary and secondary schools. In addition, this study advocates for interdisciplinary collaboration among educators in primary and secondary schools which must be pioneered by the department of education. It was further recommended that knowledge exchange and knowledge transfer be facilitated, and specialized training in the development and use of technology, software, and other teaching materials for educators in primary and secondary schools be provided

Published: July 2024

Tax regulations undergo dynamic changes in every period of time. This also occurs in tax regulations for income tax 21 (PPh 21), one of which is individual income such as TER (average effective rate). With the average effective rate, individual taxpayers can now find their non-taxable income (PTKP) value more easily. This study intends to examine the effect of changes in the average effective rate (TER) on taxpayers' perceptions of their satisfaction and loyalty at KPP Pratama Gresik. A quantitative approach is applied in this study, with primary data collected through questionnaires distributed to individual taxpayers at KPP Pratama Gresik. The population of this study is all individual taxpayers at KPP Pratama Gresik, with a sample of 100 respondents obtained through accidental sampling technique. Data analysis shows that changes in TER (average effective rate) have a positive influence on the level of taxpayer satisfaction at KPP Pratama Gresik, in accordance with the first hypothesis. The results also support the second hypothesis which states that changes in TER (average effective rate) have a positive influence on taxpayer loyalty at KPP Pratama Gresik. The research contribution for the Directorate General of Taxes (DGT) is that in terms of increasing the tax revenue target, it must be driven by a sense of satisfaction and loyalty of taxpayers in paying taxes.

Published: July 2024

Background: The COVID-19 pandemic has disrupted health systems globally, affecting various services, including immunization programs. This study evaluates the impact of COVID-19 on immunization program financing and service delivery in Zambia, a lower-middle-income country, to understand how such disruptions could reshape future healthcare priorities and funding.
Methods: The study employed a mixed-methods approach, integrating both qualitative and quantitative data collection. Data were gathered at national and sub-national levels, including in-depth interviews with 36 healthcare workers and an online survey completed by 44 staff members. The evaluation focused on the changes in government funding, the effect on static and outreach immunization activities, vaccine supply distribution, and the impact on human resources within the Expanded Programme on Immunisation (EPI).
Results: Findings indicated that while regular disbursements to districts improved in 2020, there was heightened competition for limited resources due to COVID-19, leading to a redirection of funds from routine immunization to pandemic-related activities. The study revealed a significant decline in immunization coverage, attributed to reduced health facility visits and outreach sessions. Additionally, financial constraints heightened by the pandemic made it challenging for districts to accommodate the extra costs associated with implementing COVID-19-compliant immunization services. Human resources for immunization were also impacted, with staff being reallocated to COVID-19 response activities, thus increasing workload and stress levels among remaining personnel.
Conclusion: COVID-19 has substantially affected the funding, delivery, and human resource components of Zambia's immunization program. Despite an increase in regular funding disbursements, the redirection of funds to COVID-19 activities has strained routine immunization services. The pandemic has highlighted the need for robust health systems that can withstand global health crises without compromising essential services like immunization. Recommendations include closer monitoring of immunization service delivery impacts, assessment of COVID-19's financial implications on immunization, development of clear protocols for service delivery under pandemic conditions, and a re-investment in community engagement and education post-pandemic.
BREAST TUBERCULOSIS: A RARE OCCURRENCE WITH DIAGNOSTIC CHALLENGE IN A 21st CENTURY NIGERIAN FEMALE
Authors: Agada Horace , VECHU GRIMAH , TANZE JOSEPH GODWIN
Published: July 2024

Tuberculosis of the breast, also referred to as tuberculous mastitis, represents an extremely rare presentation of tuberculosis. It constitutes < 0.1 % of all breast pathology and <2 % of all tuberculous cases.
It’s an infrequent manifestation of extra-pulmonary tuberculosis. It is characterized by diagnostic challenges with majority of preliminary clinical diagnosis being breast carcinoma or pyogenic breast abscess. The diagnosis is challenging due to the non-specific clinical and radiological findings, in addition to insufficient specimen with often negative microscopy and culture results.
We report the case of tuberculosis of the right breast in a young multiparous woman, a healthcare worker who presented with clinical features suspected to be breast tuberculosis in whom diagnosis was made based on clinical, hematological parameters and positive mantoux test only. She was commenced on empirical Anti-tuberculous medications with excellent clinical response after 6 months of therapy.
This report highlights the importance of considering tuberculosis as a differential diagnosis in women with breast lumps and sinuses. In addition, this report demonstrates the diagnostic challenges in patients with breast tuberculosis and how empirical therapy following few simple investigations  could yield the desired result.

Pediatric Autoimmune Encephalitis: A case report of three Zambian children.
Authors: Tembo Derby , Nkole Kafula Lisa , Kawatu Nfwama , Bergin Ann M
Published: July 2024

Autoimmune processes are a common cause of acute encephalitis in both children and adults. Autoimmune encephalitis (AE) is caused by a pathological immune response against neuronal autoantigens.  It is a treatable and under-reported condition in sub-Saharan Africa. Attributable factors include low index of suspicion among clinicians, few neurologists and limited access to diagnostic testing for autoimmune antibodies. The complexity of dynamic childhood behaviour and overlapping clinical syndromes associated with brain inflammation make the diagnosis even more challenging to identify in the pediatric population. Clinicians must have a high index of suspicion of AE when a previously healthy child present with new onset symptoms of acute encephalitis unresponsive to antimicrobials, with associated abnormal behaviours, seizures, movement disorders and sleep disturbance with symptoms involving over 3 months of duration. Increased awareness among healthcare personnel and accessibility to diagnostic tools are warranted in resource-limited regions to facilitate early diagnosis and intervention of probable cases.
Tunable Pulse Amplitude and Position Modulation Scheme
Authors: Ramlee Nur Hazwani Binti
Published: July 2024

In optical communication applications, there are always trade offs between system performance and costs. Therefore, there is need to design a modulation technique to prevent this problem in terms of their power and bandwidth requirements. Basic technique such as On Off Keying (OOK), Pulse Amplitude Modulation (PAM) and Pulse Position Modulation (PPM) have been validated as suitable for the optical wireless channel. The method employ amplitude and position modulation technique, a guaranteed system performance can be secured, without compromising power and bandwidth. The example model will stabilize the Bit Error Rate (BER). However, a latest modulation technique which is combining L-level pulse-position modulation (L-PPM) and L-level pulse-width modulation (L-PWM) which have a relatively low bit error rate and improved power and bandwidth efficiencies is the better hybrid modulation compared to the Pulse Amplitude and Position Modulation. Extensive simulations using a Matlab will be carried out to validate this two technique.

The growing concern over environmental sustainability and the need for innovative waste management solutions have spurred interest in the utilization of waste resources. This study investigates the potential of utilizing activated charcoal produced from Doum Palm (Hyphane thebaica L.) bark as a dopant to improve the electrical and thermal conductivity of polymeric waste materials. The doped materials were formed by incorporating varying proportions of activated charcoal into the polymer matrices through a melt-blending technique. The resulting samples were then subjected to certain characterization processes, including FTIR, SEM, Physico-Chemical analysis, and electrical and thermal conductivity testing. Physico-Chemical analysis is done to determine the activation efficiency of the activated charcoal produced. Electrical conductivity is evaluated to assess the potential of these doped materials for electronic applications and antistatic properties. Thermal conductivity measurements provide insights into their suitability for heat transfer applications. Polyethylene shows the highest electrical conductivity of 1.82 × 10-3 S/cm at 10wt% dopant concentration, with polypropylene performed best for thermal conductivity. The findings of this study contribute to the development of sustainable materials with improved properties from waste polymers. Hence, it is evident that on further modification they can be used for various applications, such as the development of conductive materials, used in electronics industries, contributing to the promotion of economy practices and reducing environmental impacts associated with polymer waste disposal.

Objetivou-se mensurar as alterações nutricionais em feno de aveia branca do corte até 56 dias de armazenamento em galpão coberto e com ventilação. Adotou-se o delineamento inteiramente casualizado com tempos de amostragem: -3 (corte); zero (enfardamento); sete; 14; 28 e 56 dias (períodos de armazenamento). As amostras foram analisadas bromatologicamente estimando-se os teores de matéria seca (MS), matéria mineral (MM), matéria orgânica (MO), proteína bruta (PB), fibra em detergente neutro (FDN), fibra em detergente ácido (FDA), hemicelulose, digestibilidade da matéria seca (DIGMS), nutrientes digestíveis totais (NDT), consumo de matéria seca em percentual do peso vivo (CMSPV) e valor relativo da forragem (VRF). Os dados foram submetidos à análise de regressão testando-se os modelos linear e quadrático. Constatou-se aumento nos teores de MS e PB, DIGMS, NDT e VRF até os 56 dias de armazenamento. A FDA reduziu-se durante o armazenamento enquanto o FDN e a hemicelulose elevaram-se até 30 dias com posterior redução. Os resultados confirmam que não ocorrem perdas de valor nutricional no feno de aveia armazenado até 56 dias e sugerem este período como adequado para armazenamento. Porém, são necessários estudos com duração mais longa para recomendações técnicas mais consistentes.

A utilização de cobertura vegetal vertical, em benefício estratégico ao conforto térmico e climatização passiva, é excelente alternativa arquitetônica. Na presente pesquisa, o efeito da parede verde com relação ao conforto térmico, foi avaliado por meio da reprodução em escala reduzida, com dois modelos construtivos de edificações: steel frame e bloco cerâmico, ambos sendo com e sem a utilização da parede verde. Foram monitorados parâmetros de temperatura e umidade relativa do ar interno, através da utilização de sensores do modelo SNOFF TH16, e os dados de temperatura externa foram coletados de fonte meteorológica, disponibilizada pela Fazenda Escola do Centro Universitário FAG. Como avaliação dos dados coletados, o dispositivo foi calibrado pelo método de comparação realizado no sensor, utilizado em experimentos anteriores, o qual foi mantido como base referencial. Para o experimento, foram utilizadas duas espécies de vegetações: Tradescantia zebrina – lambari roxo e Asparagus densiflorus – Aspargo, previamente cultivadas em floricultura, para promover o devido sombreamento. O sistema de execução da cobertura vegetal vertical, é      composto de suporte plástico que abriga as plantas enraizadas sob substrato, que contém terra com húmus, argila expandida e substrato, com sistema de rega manual. Desta forma, foi possível avaliar o comportamento de cada modelo de edificação perante a utilização da parede verde, monitorado por um período de onze meses, e avaliado as quatro estações do ano. Os dados foram registrados diariamente, pelo aplicativo eWeLink, a cada duas horas, entre 6h e 24h. A cobertura vegetal vertical pode ser utilizada como estratégia de climatização passiva nas edificações, pois obteve-se como resposta, a diferença de temperatura de 1ºC, mais baixa, no módulo com cobertura verde em relação ao módulo sem cobertura, sendo o material steel frame, mostrando resultado mais expressivo.
